Patented Nov. 24, 1931 "UNITED, STATES PATENT OFFICE CHARLES J. FANCHER OF WINDSOR, VERMONT, AND ROBERT A. OI-Ill'SOlT, OF LONG- MEADOW, MASSACHUSETTS, ASSIGNORS, BY MES'NE ASSIGNMENTS, TO VIOODWARD, HUBBARD COMPANY, OF HILL, NEW HAMPSHLRE, A CORPORATION OF NEW HAMP- BLANK FEEDING MECHANISM Original application filed January 12, 1927, Serial No. 160,839. Divided and this application filed December Our invention relates to improvements in mechanism for assembling into units or sticks of a predetermined number of objects, such as glaziers points, the same being a divisional part of our application for Letters Patent ofthe United States, filed January 12, 1927, Serial No. 160,639. i i

The primary object of our invention is to produce highly eiiicient mechanism for dividing into units or sticks of predetermined lengths or numbers, from trains of objects, such as glaZiers-points, whereby the sticks objects or points produced are in condition suitable for being packed into boxes, and for use when removed from said boxes.

it may be noted, in passing, that with this mechanism mechanical count of the points or other objects, after they have been cut and as they pass on their way to be boxed or otherwise disposed of, is made.

A further object is to provide mechanism of th s character with means which is comparatively simple to convey or transfer the SldCli'S, after being cut from the trains, from av fixed carrier to a fitted slide, in order to enable said sticks to move on toward the bOX- ing mechanism by gravity, and properly to control such movement.

Another object is to afford convenient means for applying powder to the sticks for the purpose of facilitating the movement thereof and preventing them from becoming stuck together after being packed in their boxes. I d

Other objects and advantages will appear in the course of the following description. A preferred embodiment of the invention,

whereby we attain the objects and secure the.

advantages of the same, is illustrated in the accompanying drawings, and we will pro ceed to describe the invention with reference to said drawings, although it is to be understood that the form, construction, arrange ment, etc, of the parts in various aspects are not, material and may be modified without departing from the spirit of the invention.

We have illustrated our assembling mechanism in connection with or as a part of a glazierspoint machine, and will describe so much of said machine as is shown or may be necessary fully to understand said mecha nism in both structure and function, although it is to be understood that said mechanism can be applied to or used in connection with a machine or machines other than a glazierspoint machine.

The glaziers-point machine is designed to cut ten metallic strips into diamond-shaped glaziers points, and to handle ten rows or trains of points after being cut, and the assembling mechanism is provided to separate said trains into ten sticks of 100 points each, at each cycle of operation of the machine and mechanism. It is to be understood, however, that the number ten as applied to theassembling mechanismmight be increased or decreasedwithout changing any essentlal feature of said mechanlsm or departmg from the invention. Even a single train of points or other objectsmight be fed to the assembling mechanism and by the same separated into sticks each of a predetermined length and which is transferred or passed on to be boxed or otherwise disposed of, or mechanism might be built to handle the single train and the single stick; and it naturally follows that mechanism might be constructed to handle more than tenst'icks. The ten-unit mechanism is the best formost practical purposes Inasmuch as the strips from .which the 'points 'are out are fed vertically to the cutters,

' :it is preferredt'hat eachpoint be equal, in

width between either pair of its oppositely disposed edges to the width of'the stripfrom which the point is cut, the cutter-head is set at an angle of 40 to'the vertical plane of said strip, that being the degree angle of said parallel edges of said point when the latter is placed vertically on one of said edges;

A table 1 may be used on which to support the machine, including parts and members of the assembling mechanism. A bed block 2 is mounted on and secured to the table 1 adjacent to the right-hand or. front end of saidtable, and aframe 1 is mounted on and secured to said table at the left-hand or rear end thereof. The side of the frame 1' that is toward the frentend of the table is the part ofsaid frame which is directly sup: ported on said table, and the other portions of theframe extend rearwardly and upwardly from the opposite end ofsaid table.

The'frame inclines a little toward the front end of the table. Extending from the frame at the bottom, beyond the rear end of the table, isan arm 5in front and .a brace 6 behind for said arm; and extending from said frame near the upper end, in front, is an arm terminals of thearms 5 and 7 i The slide 8 extends beyond so that itis inclined downwardlythroughout its length and at the same time inclines trans- Verselyof its'lengthatthe forward side of the machine.

A portion of the bedblock 2 inclines at an angle of 40 downwardly from theriear to V the front side of the machineto provide a bed c.9ffor. a cutter-head represented at 14. Bolted to two lugs 9 atthe right handend of the bed r Afslide S is securely attached to the outer p and away frombhetabl 1. As shownin Figs. 'T-and 11, the brackets 6 and 7 support and hold the slide 9 are two bearings 11 in which isjournaled a shaft 13, the same being the main drive shaft for the cutter-head 14-, and for the movable parts of the assembling mechanism.

Mounted on and secured to the bed block 2 is a bracket 15. 'Having their bases firmly seated in the bedblock 2 are posts 16, and these posts are rigidly connected by a platform 17 .on which is mounted a motor 18. The bracket 15 is in front of the posts 16. Secured to the post 16 that is nearer to the front end of the machine is a bracket 19 that extends towardthefront side of the machine.

Secured to the posts 16 which are adjacent chine, and has a bearing 23 for the forward terminal of a shaft 241. The bracket 22' ex tends upwardly at the outer terminal and the bearing 23 isformed at the top of this upwardly extending part,'but said bearing has an inclination to the top of the table lengthwise, with the higher end of saidbearing towards the front end of the table;

Secured to theback side of the frame at is a bracket 25 having a bearing 26, inclined like the bearing 23, for the rear terminal of the shaft 24, said first-named bearing therefore being on a lower level than the other. Thus it is seen that the shaft 24 inclines downwardly and rearwardly-from the front to the rear end thereof,and is located behind and above the vertical plane of the back side and the horizontal plane of the top of the table 1, respectively. The shaft 24: is provided with a ball-bearing 27 at the inner end of the bearing 26, thro ghthe medium ofwhich ball-bearing said shaft is prevented from moving in the direction of its length rearwardly in said bearing, but the means of prevention iso'f the anti-friction type so that it does not materially interfere with the rota- 7 tion of the shaft. 1

The motor 18 has a shaft 28 which extends outwardly on the back side of themachine,

and a pulley 29 is mounted on and secured to said shaft. The pulley 29 is connected by means of a belt 30 with a similar pulley 31 7 below. The pulley 31 is mounted on and securedtoa horizontal shaft32., The shaft 32'is journaled in two bearings 33 atlthetop of a movablecarrier 34 held against the'frontside ofthe upstanding part of the bracket 15 byrmeans of two bolts 35 which pass through the two vertical slots v36 insaidcarrier, said bolts being sufficiently loose to enable the carrier .to be raised'and lowered. The pulley 31 is at the outer end of the shaft 32,and

mounted on and secured to. said shaft at the inner endfisa small friction cone37. Mounted on and secured to the cutter-head shaft 13 is aworm 38, and intermeshing with said worm is a worm-wheel 39 mounted in and secured to a short shaft 40 atthe outer end thereof, the inner end of said short shaft being connectedby means of a universaljoint 41 with the forward terminal of the shaft 24. The bracket 19 has at the outer end a bearing 42 for the shaft 40. Mounted on and secured to the shaft 13, in front of the worm 38, is a large friction cone 43 which is driven by the friction cone 37' when in engagement with the large cone. Mounted on and secured to the shaft 24 at the rear terminal is a worm 44, and this inter-meshes with aworm-wheel 45mounted on and secured to atransverse shaft 46. The worm 44 is contiguous with the outer end of the bearing 26. The shaft 46 is journaled in bearings provided at the rear ends of a pair of brackets 47 that extend outwardly from the uprights of the frame 4. The shaft 46 extends beyond the frame 4 to position the worm wheel 45 over the worm 44.

The carrier 34 has a vertical bolt 48 tapped into and through the horizontal part of the same, which bolt is provided with a checknut over said horizontal part. The lower, protruding end of the bolt 48 bears on a cam 50 which has a depending stem 51 that is journaledin the base of the bracket 15. The cam 50 has a tail-piece which extends to the'left, and is provided with a depending rod 52. Pivotally connected with the lower end'of the rod 52 is a link 53, and pivotally connected with the forward end of said link is a horizontal operating rod 54 provided at its forward end with a handle 55. The rod 54 is supported and adapted to slide in aguide 56 secured below the forward, lower lug 9 to the side of the bed block2 from which said lug projects.

The form of the cam 50 and the construction and arrangement of the operating members therefore are such that, when the rod 54 is drawn forwardly, said cam, through the medium of the link 53 and the rod 52 is partially rotated in the bearing for the stem 51 in a manner to permit the bolt 48 and the parts supported thereby to descend, and thus move the friction cone 37 from engagement with the friction cone 43 and disconnect the cutter-head shaft 13 with all the parts and members driven and operated by said shaft; and, when said first-named rod is positioned rearwardly, said cam, through the same medium as before, is actuated in the opposite direction and raises said bolt and the aforesaid parts and'mem'bers far enough to cause said first-named cone to engage said secondnamed cone, whereby'said shaft and members driven and operated thereby are set in motion. The weight of the carrier 34 and the parts and members supported thereby is sufficient to cause the same to descend when the cam 50 is actuated by the rod 54 in being drawn forward. The slots 36 in the carrier 34 permit of the vertical movement of said carrier as just explained. This movement is comparatively slight, and the belt 30 is sufficiently loose to permit of said movement, but not so loose to fail to drive the pulley 31 and the shaft 32 when the carrier 34 is in elevated position.

It will now be seen that the motor shaft 28 drives the shaft 32 through the medium of the pulleys 29 and 31 and the belt 30; and that, when the cone 37 is in engagement with the cone 43, the shaft 13 is driven and with it the worm 38, that said worm drives the worm-wheel 39, the shaft 40, the universaljoint 41, and the shaft 24, and that said lastnamed shaft, through the medium of the worm 44 and the worm-wheel 45, drives the shaft 46. The shaft 46 is a cam shaft from which is operated the movable parts of the assembling mechanism. The universal-joint 41 is necessary because of the presence of the worm 38 and the worm-wheel 39 and the angular relationship existing between the shaft 40 and 13.

A suitable fixed carrier extends between the cutter-head 14 and the frame 4, and the rear-end portion of said carrier, which is the portion connected with and supported by said frame, is indicated by the numeral 57. In the carrier 57 are ten longitudinal channels 58 to receive ten trains of points out and moved into the same from the cutter-head. The channels open through opposite ends of the ca *rier 57.

t is customary to apply wax to the points, as they move through the intermediate por tion of the carrier 57, for the purpose of causing said points to adhere to each other. The points are cemented together temporarily for convenience in packing them in boxes, and in t referring them from the boxes to the drhers with which the points are applied to wi dow sashes. The channels 58 at and adjacent to their left-hand ends open through he bottom of the carrier 57 as represented at 59 in Figs. 3, 7, and 11. Surplus wax pushed along by the trains of points to the rear end of the carrier is received in the slots 59 and from time to time is picked therefrom. The carrier 57 longitudinally inclines upwardly to the frame 4, and said carrier inclines transversely downwardly and forwardly from back to front.

The upward inclination is for the purpose of preventing the trains of points from brealn ing apart or opening before they arrive at the rear end of saidfcarrier, as they might possibly do were said carrier horizontal, and the inclination in the other direction, that is, transversely, is necessary because of the peculiar setting of the cutting mechanism here required in order to produce diamond-shaped points.

fThe inner end of the-slide 8 is somewhat.

tween said ends. lit the lower, outer end the slide 8 is horizontal. The slide 8 has ten yond the head 63, and it is in this longitudinal channels 61 therein, and the carrier has the same number of channels 62 in the upper front side of the same. The channels 62 align with the rear ends of the channels '58 in the fixed carrier 57, when the movable carrier 60 is against the rear end of said fixed carrier, the movable carrier then having the same inclination, in the direction ofits channels, as that of the fixedcarrier,

andsaid first-named channels align with the inner, -uppcr ends of the channels 61 in the slide 8, when said movable carrier is against the inner, upper end of said slide, the movable carrierthen having the sameinclination,

' in the direction of its channels, as that of said slide. It isto be observed that the slide 8, as illust-rated in connection herewith, is somewhat convcntionalized, inasmuch as actually said slide with its channels is curved from the forty degrees at the inner end to the horizontal at the outer end. 7

The frame 4 has a head '63 at the top, which head is constructed to support the rear termii nal of the carrier 57, and support the same at the required angle. The extreme rear-end portion of'the carrier extends outwardly beportion that the slots 59 are located.

Bolted to the uprights of the frame 4 are two angular brackets 64having at their rear ends up-turned arms in which is a rock shaft 65. The supporting arm 7, forthe slide 8, is adjustably bolted to the front bracket 64. Mounted on and secured to the rock-shaft 65 is a bell-crank-lever 66 having at the top a cross arm 67 on and to which the movable carrier 60 is mounted and rigidly secured.

A peripheral cam 68, consisting largely of a dwell, is mounted on and secured to the cam V shaft 46, between the arms 4 Journaled in 'the' lower'portions of the brackets v64 is a rock-shaft 69. Mounted on and secured to the rock-shaft 69' is an arm 7 O providedwith a cam plate 71 arranged to bear on the periphery oft-he cam 68, and being held'in contact with said periphery by means of a spring 72 attached at the upper end to said arm and at the lower end to the supporting arm 5.

A link 73 has its upper end pivoted at 74 t0 the short, rearwardly extending arm of the bell-cranl'c-lever 66, and its lower end pivoted at 75 to the outer end of the arm 70. i I

At each revolutionfofthe cam 68 the cam plate-71 drops into the depression in said cam, and the arm 70 swingsldownwardly on slide v8, and said plate is forced out of said depression as the high partof said cam passes beneath said plate, said arm is swung ups wardly against the resiliency of the spring 72, and, through the medium of said link and said bell-cranklever, said movable carrier is moved to the right again against said end of said fixed carrier, thereto remain until said cam depression arrives a second time beneath said'plate. What maybe termed the normal position of the movablecarrier 60 against the iixed carrier 57 is as indicated in Fig. 11. The cam 68 causes the carrier 60 to contact some what forcibly with the slide 8 and thereby to produce ajar.

The trains of points move rear-wardly in the channels 58 in the carrier 57, pass under a separator blade 76 and into the channels 62 in the movable carrier 60, until there are one hundredpoints in each channel 62, and

The movable carrier 60 is provided with two rods 7 7 that pass transversely across the channels 62 in said carrier, and prevent the sticks from being thrown outof the open sides of said channels. Q

The separator blade 7 6, which is necessarily inclined at 40, is bolted to the under side of a support or holder 78 which extends up wardly from said plate, and has on the inner side thereof at the ends sleeves 79 and 80 mounted toslide up anddown on guide rods 81 and 82, respectively, said rods rising from the frame head 63adjacent to the side thereof that is adjacent to and parallel with the rear end of the carrier57. Encirclingthe rod 81,

between the head 63and thebase of the sleeve.

79, is a spring '83; The spring83 normally retains the'holder 7 8 with the blade 76 in its elevated position, and tends constantly to restore it to said position when depressed. The upper terminal of the rod 81 is screw threaded to receivea nut 84 above the sleeve 79, which nut serves as an adjustable stop to limit the upward movement of the holder 78.

The holder '7 8 is depressed, against the resiliency of the spring 83, and with the sleeves 719, and 80 sliding on the rods 81 and82,,.by means of an approximately vertical bar 85 provided onv the inside with a dog 86,;and a trip-arm 87 The bar '85 is arranged to slide up and downin slots in a boss88 onthe frontof the arm 5 and in the head 63 above, and behind straps 89-89 fastened to said boss and head over said slots. The bar is connected with the base of the sleeve 79 by means of a bolt passing through alongitudinal slot 91 into said bar. A Washer 92 is mounted on the bolt 90 between. the head of said bolt and the bar 85. The slot 91 permits the bar 85 to be adjusted relative to the holder 78, and the stroke of the blade 76 correspondingly varied. The nearer the bottom of the slot 91 is to the bolt 90 the lower the blade 7 6 is carried on its downward stroke, and vice-versa. The dog 86 is located on the bar 85 a little above the 9 boss 88. The trip-arm 87 is mounted on and secured to the cam-shaft 46 above the boss 88, and the dog 86 is in the path of the outer terminal of said arm.

' At each revolution of the cam shaft 46 and of the trip-arm 87 said trip-arm encounters the dog 86 and causesthe bar 85 to move downwardly momentarily, and said bar is carried with it.-against the resiliency of the spring 83,the members mounted to slide on the rods 81 and 82. with the result that the blade 76 is carried downwardly at the proper time to sever the points on the movable carrier 60 from the trains in the fixed carrier 57. At this time the movable carrier 6-0 located a ainst the rear end of the carrier 57. and the instant the one thousand points have passed into the movable-carrier channels 62 (100 from each channel 58 into each channel 62) the blade 76 descends. This action of the blade 76 produces ten sticks of points. The descent and return of the blade 76 is almost instantaneous. otherwise the points, which are continuously being fed out of the channels 58 in, the carrier 57 would jam against the blade. As soon as the blade 76 has severed the ten sticks of points. which sticks upon being severed drop into the channels 62 in the carrier 60, said carrier is actuated by the cam 68 and the-spring 72 over against the slide 8 and deposits said-sticks by shock and gravity in the, slide channels 61. The ten sticks of pointsfrom the carrier 57 are pushed or fed out into'space a short distance, but the carrier 60 is returned quick- 93 ly by the cam 68 into supporting and receiving position beneath the protruding portions of said sticks.

Although the blade 7 6 oscillates in an approximately vertical plane it is inclined lengthwise, as previously noted.

It is by means of the blade 7 6 that the mechanical count of the machine equipped with this mechanism is'obtained, since said blade is timed one hundred to one with the mechanism for cutting and feeding the points into the channels 58 in the carrier 57. At each downward movement of the blade, therefor, 100 points from each of the ten trains are cut off.

To facilitate the movement of sticks of is fastened to an arm 94 which in turn is secured to the part of the head 63 from which the rod 8:2 rises. The sides of the container 93 converge from above downwardly, and in the bottom of said container are perforations 95. A roller valve or agitator 96 is located on the bottom of the powder container, and said agitator has a rigidly attached finger 97 which extends downwardly therefrom through a slot 98 Fig. 7, in said bottom. The agitator 96 is provided with sets of radial perforations 99 arranged therein so that those in one set are in a plane which intersects the plane in which those in the other set are located, and those in one set are over the perforations 95 in the container 93, when the agitator is disposed in one extreme position, and those in the other set of said first-named perforations are over the second-named perforations, whensaid agitator is disposed in the other extreme position-see Fig. 6. Fastened to the upper or rear side of the slide 8 adjacent to the inner end thereof is a spring pressed latch 101 which carries a rod 102, and the agitator finger 97 is in the path of said rod. The container 93 is inclined like the blade 7 6 and certain of the other parts.

In the backward and forward movement of the carrier 60 the rod, 102 encounters the finger 97 and said finger causes the agitator to be oscillated, whereby the powder in the container 93 is agitated and a certain portion of the same is caused each time to escape, by Way of one or the other sets of openings 99 and through the openings 95, onto the points below.

By gravity the ten sticks that have been deposited in the channels 61 in the slide 8 move down said slide until the leading ends of said sticks arrive at a downwardly extending lip 103 at the lower or outer side edge of a movable stop 104;, said lip normally being against the rear ends of said channels. An arm 105 extends from the center of the top of the stop 104 toward the back side of the slide 8, and is rigidly secured at its outer end to the rear end of a plunger 106 mounted to slide and rock in two bearings 107 at the outer ends of two arms 108 bolted to the under side of said slide. The stop 104, when in normal position, extends across the top of the slide 8 adjacent to the lower, rear, or outer end thereof, with the lip 103 against the extreme outer end of said slide, and the ends of said cross rods 109, with which said stop is provided, then rest on a pair of tracks having their inner ends secured to the top of the slide 8 adjacent to said end. The tracks 110 extend downwardly and rearwardly beyond the slide. The rods 109 project beyond both ends of the stop 104 to bear and ice ride on the tracks 110. A sleeve 1:11is mounted on the plunger 106 between the bearings 10?, and is keyed to said plunger in order to enable the latter to slide in said slee ve,';and also, when partially rotated to rock said sleeve with itsee big-:11. It follows, therefore,

that, when the plunger106 moved longr tudinally,it carries with it the step 104, the rods .109 then ridingon the tracks 110; and, when said plunger 'isrocked in one direction, it swings said stop upwardly, through the medium' of the arm 105 and the sleeve 111, and. when said rod is rocked 1n tlIGOPPOSltG.

direction, said stop returned to its former position with said rods on said tracks.

A curved lever 112 has its rear endipivotally connectedat 113 with the upstanding parts of the frame4, and is provided on the back side intermediate of the ends with a 'n'al received in a notch 122m the free ter cam roll 114., A link 115 is pivotally connected at theinner'enchasat 116, with the upper terminal of the lever'112, and has its opposite end pivotally connected at 117 with the inner or rear terminal of the plunger 106. Secured to the back side of the cam 68 are two cam plates 118 and 119 which form between thema' cam groove 120 for theroll 114. i r

' Asthe lever 112 is oscillated by the roll 114'in the cam groove 120, at'each revolution of the cam 68, the link115 is caused to impartan oscillatory movement to the plungor" 106, and through said plunger and the arm 105 to the stop 104. The dwell in the vcam groove 120 is such that the stop 104 is retained in retracted position during about one-half of the revolution of said cam. V

A bent rod 121 extends radiallyfrom the underside of the sleeve 111, and then'upwardly andforwardly to have its free termiplate 125 encounters the roll 124 and rocks the arm 123'upwardlv on the pivot 113, and said arm carries with it thec'on'nected terminals of the armi 121 and thus rocks the sleeve 111 and the plunger 106, with the re sult that the arm 105 swung upwardly with said plungerv andraises said stop into the ,position'shown in Fig. 11. As soon as the cam plate 125 passes beyond the roll 124, the

lever 123 rocks downwardly, and, through the medium of the arm 121 imparts a partial revolution in the opposite direction to the sleeve 111 and the plunger 106, whereby the stop 104 is swung down until the rods 109 come to rest on the tracks110. The arm 105 has a pivotal connection at 126' with the stop 104; and the tracks 110 at their inner terminals are slightly elevated, as shown at 127-427, whereby said stop is raisedat the 129 is rigidly secured at its inner end to. the

outer end of the slide 8, and this trough receives the sticks as they slide down with the stop 104, and after said stop releases said sticks they continue to slide until they oncounter aigate 130; The end of thetrough 129 which is in contact with the slide 8 cor responds in width with the combined width of the'channels 61 at their rear ends, but said sides converge toward the opposite ends of said trough, so as to cause the sticks, as they slide down in said trough,- to come together and closethe spaces made by the channel partitions of the slide. v I

The gate 130 isa thin plate that extends across'the trough 129, and the upper'end of said gate is clamped to the rear end of an arm 131 whichextends rearwardly from the horizontal part of a U-shaped rocker 132 mounted on and extending above the slide 8. One downwardly extending arm of the rocker 132 is pivotally connected at 133 with the back side of the'slide 8 near the'lowerend thereof, and the other downwardly extending arm of said rockeris rigidly attached to the upper part of a curved arm 134'which is pivotally attached at 135 to said slidediametrically opposite "to the pivot 133. The arm 134 extends downwardly and forwardly,

and has at the'forward end a pin 136 which is received in a slot 137 in the free end of a lever 138. The, lever 138 is pivotally con nected "at 139 'with the frame 4, below the pivot'113, and said lever isprovided with a roll 140 which is in the path of the por tion of the outer edge of the cam 68 that assists informing the high part ofthe cam groove 120, such part being indicated at 141. Normally the gate 130 rests on the trough 129. and at such timethe roll'140 is out of contact with the cam plate 119, but, when the cam edge 141 of said plate'encounters said rolllthe lever 138 is rocked downwardly on the pivot 139, imparts afdownward movement to the arm 134, and thus rocks said arm and the rocker 132 on the pivots 133 and135 forwardly, and causes the arm 131 ands'aid gateto be raised into the position shown in Fig. 11. -As soon as the cam edge 141 passes clear of the roll 140, the lever 138 is rocked upwardly, and, acting through the arm 134 and the rocker 132, swings the arm 131 and the gate 130 downwardly until said gate rests on the trough 129. i

The lever 123 is yieldingly held in its downward position by means of a spring 128 having the upper end attached to said lever and the lower end attached to the brace 0, and the lever 138 is ieldin 'l retained in its elevated position by means of a spring 142 h swing the upper end attached to the frame l and the lower end attached to said last-named lever,

- In practice, when ten sticks of points in the channels 61 arrive against the lip 103 of the stop 104:, the latter with said stick moves downwardly, thesticks sliding, from said channels into the'trough 129, said stop is elevated and releases said sticks which continue to slidedown in said trough until they contact with the gate 130, said gate is raised, and the sticks, still in the trough, move on by gravity. i

During each cycle of the mechanism, the stop 104 is swung down with its supportin rods 109 on the tracks 110 and act ate-d until the lip 103 is against the rear end of the slide 8, and the gate 130 is lowered into the trough 129.

The operation of the mechanism as a whole is described as followsr The switch 21 is thrown to set the motor 18 in motion, and the rod 54 is forced 'rearwardly to elevate the friction cone 37 into engagement with the friction cone 43. The driving and driven parts of the mechanism are new in motion. As the points are cut they force those previ ously cut and already in the channels 58 in the fixed carrier 57 along in said channels in trains. These trains first pass through a hot wax, cementing compound and eventually pass at their rear ends beneath the separator blade 7 6 and into the channels 62 in the movable carrier 60'. As soon as the movable carrier 60 is loaded the blade 76 is caused to descend and cut or separate the parts of the trains or the pluralities of points in said carrier into ten sticks of 100 points each, it being understood that said blade operates while themovable carrier is in position against the rear end of the fixed carrier, and as soon as onefthousand points have passed into the movable carrier channels. Then the carrier 60, which is operated by the cam 08 ant the intervening mechanism, is moved against the upper, inner or forward end of the slide 8, striking the same with an impact sutiicicntly forceful to insure the transfer of the ten sticks from said carrier to said slide. I By ,e ravity these sticks slip down. in the channels 61 in the slide 8 into contact with the lip 103 of the stop 104. By means of the cam plates 118 and 119 and the mechanism operated. thereby. the stop 104 is carried down and with it the sticks retarded by the lip 103, until said step is elevated by means of the cam plate 125 and the mechanism operated thereby, when said sticks slide down against the gate 130, the sticks during this time being in the trough 129, having passed into the same as soon as they left the slide 8. From the trough 129 the sticks are delivered or passed to the boxing mechanism of the glaziers-point machine, hut may be delivered for disposal otherwise than by being packed in boxes. Before the ten sticks in the next leading set arrive at the lower ends of the channels 61, the stop 104 is returned to position to receive said sticks as before. The second cycle of the mechanism follows the first with similar results, and so on indefinitely.
