To all whom it may concern:

Be it known that I, CHARLES W. BOWEN,

bfLynn, in the county of Essex and State of trated embodiment of the invention is effect- Massachusetts, have invented certain new and useful Improvements in Heel-Building Machines, of Which-the following is a specification. This invention relates to heel-building machines, and consists of a machine by which a heel is built up of a series of lifts which are automatically assembled successively'. I

The assembling of the lifts in the illused by arranging in a series a plurality of lift hoppers or magazines, and moving a heel carrier so as to pass the magazines successively and take from eacha lift in such way that it builds up into a heel pile those taken from the previous magazines.

In addition to the mechanism for auto-' matically assembling the lifts tofornraheel,

the inventionalso consists'of means for securing together the lifts forming the heel by applying cement to the lifts individually, and, as a further. refinement,.means for finally securing together all the lifts of a built-up heelby drivin a fastener therethrough. I

Before proceeding to a description of the machine, I desire to have it understood that HEEL-BUILDING MAC I v I Specification of Letters Patent.

order to permit the r variety of other embodiments in addition to that illustrated. Inthis connection? particular attention is called to the use, throughout Patented July 2c, 1915.: Application filed August-.16, 1907. Serial No. 388,827. 3

the specification and claims, of the term".

lift to designate the layers or blanks of which the heel produced by the machine i. composed. The term lift is used herein in an inclusive sense as defining any blank or layer of material capable of being used. in

the formation of a heel pile, from which a heel' s ultimately produced, irrespectiveof the particular shape of the blank or the nature of the material of which it iscomposed. I

The same reference characters indicate the.

same parts'wherever. they occur.

In the embodiment of the invention illustrated in the-drawings l0 is a' bedplate,

above Which is aseries of magazines each open at the bottom and adapted toc'ontain a pile of heel lifts a. The bed plate 101's supported on longitudinally extending frame pieces 11 and 12, which are supported in parallel relation .upon upright frame pieces l3, 13. The frame pieces 11 and 12 are fOrmed Wit-h guides 1-1 1%, on which a carriage 15 is adapted to slide back and forth under thelift magazines and below the bed plate. 10. The carriage 15 is pro vidcd with a movable carrier .16 havinga finger 14' The series of magazines extends from which extends through a longitudinal slot 18 in the bed plate, and which is actuated so;

front to rear of the bed plate 10 sothat the carriage 15 passes under them successively,

and they are arranged at successively greater heights above the bed. This arrangement of the magazines is forthe'purpose of permittinglthe passage thereunder of the increasingpile of lifts of which the finger l7 removes one from. each magazine. Each magazine comprises a hopper 2-0 supported on av two-piece bottom plate :19 of Which the two pieces are separated by a.

' space s'ufiicientfor the passage therebetween' of the pusher finger 14. -Each hopper 20 is adapted to contain a Y il the. lower mostlift, the'rear portion or. the bottom edge pile cflifts, and,.in

of the hopper is cut away as indicated in Fig. 3, by the numeral 21. The outer edges of the bottom plate 19 are aflixed to vertical adjustable blocks 22 mounted on brackets 23 spondingly elevate the finger 17 step by step as it advances, so as to cause it to engage the edge of the bottom lift of each magazine.

For this purpose. the carrier 16 is provided with trundle rolls 25 which run upon tracks 26. The plane ofthe tracks immediately below the magazines is preferably parallel with the path of movement of the carriage, but-inclined between the magazines so as to cause the rolls 25 and carrier 16 to rise be-.

tween each two adjacent magazines. The drawings (Figs. 1 and 3) illustrate tracks made in sections, comprising. adjustable members 27 and hinged connecting members 28. The adjustable members are mounted on adjusting stu ds 128 withwhich they have screw-threaded connection, the studs being stepped in bearings on longitudinal rails 29, of which one is aflixed to each of the side frames 11 12 (see Fig. 2). The carrierl6 is so mounted in the carriage that it is moved longitudinally of the machine by the carriage and relatively to thecarriage by the tracks 26 which elevate it, while a spring 30,

interposed in the carrier and engaging a portion of the carriage, tends to move the carrier in the opposite. direction so as to hold the rolls 25 against the tracks.

In the operation of building up a heel of lifts a contained in the several magazines, the carrlage 15 starts from the position 1n which it appears in Figs. 1 and 3, and moves from left to right, or from front to rear of the inachine. Although there are ten magazines illustrated, it is not intended that the invention should be limited to that number. Assuming that it is desired to build up a heel havingten lifts, the magazines 20 and the ,carrier' tracks 26 are adjusted so as to cause the finger 17 to engage and remove the bottom lift from each of the piles in the magazines. Movement of the carriage causes the finger v17, which extends through the slot 18 in the bed, to pass betweenthe two halves of the supporting plate 19 of the firs; magazine and to abut against the edge of the bottom lift a'bf that pile. The finger continues to move' under the second lift of the pile meanwhile pushing the bottom lift through the opening 21 at the rear of the magazine. As soon as the first lift is pushed beyond its plate 19, it lies upon the bedplate 10, bridging the slot 18 on which it is guided from one magazine to the next by guide plates 31 which prevent the lateral displacement of the lift. The latter are provided with slots giving them a range of adjustment so that they may be clamped on .the bed by their screws 33 so as to accommodate lifts of anydesired width, see Fig. 7.

'As the finger 17 passes to the second magazine, the rolls 25 of the carrier pass over the first pair of hinged members 28 of the tracks 26 to the first pair of adjustable members 27, which are at a higher plane than that portion of the track under the first magazine. The inclined portions 28 cause the rolls, together with thecarrier 16 and finger 17, to rise relatively to the bed 10 and the first lift thereon. The elevation of the portions 27 is such as to cause the end of the finger 17 to rise above the top of the first lift almost if not quite as much as the thickness of another lift. Continued movement of the carriage then causes the finger 17 to push the first lift under the relatively elevated supporting plate 19 of the second magazine, whereupon the now elevated finger abuts against the edge of the bottom lift of the said hopper. The last named" lift is then pushed through its outlet 21, and, when free of its plate 19, it lies upon the lift which was removed from the first magazine. The carriage advances, passing successively under the magazines, the finger 17' meanwhile rising step by step, and removing the bottom lift from each magazine as described in connection with the first and second magazines.

zines and having removed a lift from each, thefinger 17 pushes the pile of ten lifts a short distance beyond the last magazine as shown at 0 Fig. 6, where it subsequently receives a nail to bind the lifts together. Thus the withdrawn lifts are transferred to a common point. As the heel 0,-shown in Fig. 6, is built up of lifts of different sizes,-it will be apparent to thosev skilled in the art that the ten magazines hereinbefore described are constructed'tohold stacks of order to permit the machine to build heels having all, or a portion of itslifts, of the same size, the magazines are removable and After having passed all of the maga-' heel lifts of different sizes respectively. In

interchangeable by simpl unscrewing the studs 24, see Figs. '2 and so that any desired combination of lifts may be assembled in a pile. Although the drawings illustrate s'omewhat'conventionally a convenient form ofnailing mechanism, the-latter is not essential as a.- part of a heel-buildin machine; for it will be understood that, .lnstead of that, the heel lifts might be fastened by a nail driven manually. The last pair of guide plates '31 are provided with spring clips 3i which hold the lifts intact in the form of a heel during the operationof the nailing mechanism hereinafter described. Meanwhile the carriage 15 returns to its initial position so. as to repeat the building ope?ation. During the return trip of the carriage, the finger '17 again engages the now bottom lifts in the magazines, but it is ineffectual by reason of being mounted so as to be displaced by them. The finger is shown in Figs. 2 and 3 as being mounted between two ears and upon a pivot 36 extending therethrough. Shoulders formed on the under side of the finger are adapted to engage the supporting carriage, and,

while they permit a certain amount of tilting movement of the finger, they limit the same so that the finger cannot tilt forward when setat its initial position as in Figs. 1 and 3. It can, however, tilt rearwardly from this position, but, with slight friction which is afi'orded by the ears 35, it remains in whatever position it is left. Inreturning to the front of the machine after leaving a heel between the clips 34, the finger 17 is caused by its'engagement with the bottom lift in the rear magazine to tilt rearwardly until its free end dips below the lift, and so to dip step by step as it engages each succeeding bot-tom lift. After passing the forward magazine, a nose 37 formed on the finger abuts against an adjustable stop 38.

by means oi which the finger is tilted forwardly and upwardly to its original upright positio a. The finger is then in operative position ready for the next trip of the carriage toward the rear of the machine.

Any form of mechanism may be employed to reciprocate the carriage 15 in its guides 24, that here n shown comprising cords 4:0 (or other flexible power transmitter) which pass around .dle pulleys ll 41. The outer ends of the Cords 4O 40 are attached to the carriage. and their inner ends are made fast to a driving pulley The latter is affixed upon a rotatable shaft 43which is driven alternately in opposite directions. F or this purpose the shaft is provided with a pinion 44 which intermeshes with a reciprocatory rack The rack is pivotally connected to one end of a pitman' 46 whose other end is 'OIII'IBCtQd to a crank 47 formed on a power shaft 4-8. 49 and 50 are the pulley and bolt by which the shaft 43 is rotated continuously in one direction, transmitted to the shaft 43 bythe roman .ions described in the form of osill rim '1 uweincnt.

is a detail of construction, each lift magazine 2O isprovided with. an adjustable gate 51 (see Figs. G and L for g'a-ging. the deptn of the opening through which the lifts L-arc removed. The gate is clamped actuated so as to drive a nail into the hefi deposited between the spring clips 34. It includes a reciprocatory driver 55 a nail hopper 56, a. delivery nozzle 57 and a race 58 for conducting the nails F) from the hopper to the nozzle. Although it is not shown in detail, it may be presumed that the hop per 56 is provided with a. feeder for placing the nails in the race.

mounted. on YuTQClPI'OCfitOl'V crosshead or yoke 59, and its free end is guided toward The driver 55 is i and from the work in the throat of the delivery nozzle 57. interposed between the throat of the nozzle and the race is an osci1- v latory picker 60 having a notch 61 which receives the foremost nail in the race and transfers it to an aperture 62 in the nozzle. 'A'nail placed in this aperture gravitates into the throat of the nozzle and finally descends to a divided nail holder comprising the two halves 63 63 (see Fig. 7). Each half is pivotally mounted on a fixed stud 6d and provided with a segment of teeth which intermesh, so that movement of one half communicates movement to the other half. A spring 66 holds .the halves normally so that the supportin ends abut against each other. Each of the latter ends has a tapered notch 67 on its cooperative face, the two notches forming a split pocket into which, the point of a nail may rest until driven. The nail holder is located directly above the built-uoheel, so that, when the driver 55 descends upon the nail therein, the point of the latter wedges apart the halves of the holder and enters the heel. For oscillating the picker 60 so as to place the nails one at v oncoming nail'in the aperture 62 is prevented by the driver from entering the throat until the driver again rises. When it does rise above the aperture 62, the nail contained therein gravitates to the holder 63 and is ready to be driven into the next heel.

The crosshead 59 is mounted upon and reciprocated by a pair of parallel rods 70 .70 which move in bearings 71 on the frame. The rods are provided with collars 72 and helical springs 73 which exert their tension against the collars to depress them and drive the nail. Automatic mechanism is employed to raise the rods 70 and driver against the tension of the springs 73, and to release the same when a heel is placed under the nailing mechanism. For this purpose, the rods are connected by another yoke or crosshead 74, whose ends move in guides 75, and which is connected midway between its end to one end of a pivoted link 76. The other end of the link is connected to one end of a rocking beam 77 fulcrumed at'78. The other end of the beam is pivotally connected by a link 7 9 to a crank 80 formed 011 a rotatable shaft 81. The shaft is provided with a loose sleeve 82 having a pulley 83 and a ratchet 84. The sleeve 82 is continuously rotated in one direction as indicated by arrows in Figs. 1 and 11, by reason of being v the latter so as to normally cooperate with connected to the prime shaft 48 by a belt 85 passing over the pulley 83 and over a pulley 86 mounted on the said shaft. The shaft 81 is also provided with a tight sleeve 87 on which is pivotally mounted a pawl 88 adapted to coiiperate with the ratchet 84. A spring 89, engaging a nose of thep'awl, tilts the ratchet and transmit rotation thereof to the shaft 81. An arm 90, pivoted on a stud 91, is adapted to engage the pawl and disengage it from the ratchet. The free end of the said arm is adapted to rest upon the periphery of the sleeve 87 and to move it into the path'of the pawl when the sleeve revolves. The pawl abuts against the end of the arm and is tilted thereby against the tension of the spring 89 so that it becomes disengaged from the ratchet. A shoulder 92 on the sleeve then abuts against the pawl 0pposite the arm 90, and rotation of the sleeve and shaft 81 is arrested. The pawl is preferably located with relation to the crank 80 so that it engages the arm 90 immediately after the crank has passed the dead point at the completion of the up stroke of the rods 70. The springs 73 are then exerting their tension to force the rods 70 downwardly and to rotate the shaft 81 in the same direction in which the ratchet 84 rotates. The pawl 88 is hereby held in engagement with the stop arm 90 and out of engagement with the ratchet until otherwise released."

For releasing, the pawl, the stop arm is provided with a boss 93 which coacts with the hooked end of a bell crank 94: pivotally mounted on the free end of an arm 95 The arm 95 is aflixed to one end of a rock shaft '96 on the other end of which is an arm 97 by p which the shaft is rocked. The free end of the arm 97 lies in the path of movement of a I 1,me,996.

nose 99 formed on a reciprocatory rod or actuator 100 extending longitudinally of the machine and mounted in brackets 101 on the frame. See Fig. 2. The ends 102, 103' of.

guides 14 engages first one and then the other of the ends 102 and 103 and thereby then in the opposite direction. \Vhen it moves to the rear of the machine and deposits a built-up .heel 0 under the nailing mechanism, it engages the end 102, moving the actuator a short distance with it. This causes the nose 99 on the actuator to. engage and movethe free end of the arm 97, thereby rocking the shaft 96 so as to elevate the arm with the bell crank 94. The hooked end of the latter, which underlies the boss 93, raises the free'end of the stop arm out of engagement with the pawl 88. mechanism is thereby released and the springs 73 then depress the rods 70 together with the driving head 59 and effect the driving of a nail into the heel just placed under the nailing mechanism. The bell crank 9% in its upward movement engages a fixed stop The nailing moves the actuator first in one direction and I 105 by whichit is tilted so as to release the boss onthe stop arm 90. The stop arm then drops back until its free end strikes the sleeve 87 upon which it rests once more. The ratchet 84: meanwhile continues to re- 'volve and picks up the pawl 88 by which it is again engaged. It turns the pawl to-' gether with the sleeve 87 until the former once again strikes the stop'ar'm by which it is arrested as hereinbefore described. The

nailing mechanism has then completed its cycle of movements and is returned to itsnormally operative position. The carriage 15, when it approaches its initial position,

engages the end 103 of the actuator 100 and moves the latter so that its nose 99 leaves the rock arm 97 The weight of the arm 95 then causes it, together with the rock shaft and the arm 97, to assume their initial po sitions as illustrated by Fig. 1. In so doing, the bell crank 94 assumes its tripping position relatively to the boss 93, and all is ready to be again released when the heel carri 1' shall have deposited another heel undert. e nailing mechanism. a

The invention involves, as hereinbefore stated, means for applying cement 'to the lifts, and this is done, exceptin in the case of the last magazine, as each 1i t is removed from its hopper. The reason for omitting is because the only surfaces requiring cement are those which lie-against other lifts, the

lift from the last magazine "being on the top of the heel and upon the cement-coated sur-.- 'face of the lift below it. a"

Each magazine is provided with a cement brush 106 so mounted that its bristles wipe the upper face of each lift a as the latter is moved through the outlet 21 of its hopper during the operative trip All of the brushes,

occupy positions adjacent of the heel carrier,

' the outlets of their respective hoppers, and,

trip of the carrier, they during the return are moved laterally into engagement with a cement roll 107 from which they receive cement. Figs. 2 and 7. The roll 10'? and the cement trough 108, in which it is journaled, are supported at one sideof the machine and extend longitudinally thereof. A belt 109 passes over one end of the roll and over a pulley 110 on the prime shaft 48 and imparts rotation to the roll whose under side is kept immersed in cement. y Inasmuch-as the cement-applying devices of each magazine are identical, a description of one will be sufficient. The stem of the brush is rigidly mounted in a laterally-extending reciprocatory rack 111 mounted in hearings in the brackets 23. The teeth of the rack intermesh with a pinion 112 mounted on the upper end ofa perpendicular shaft 113 which is journaled in the brackets 23 and 101, the latter, as hereinbefore stated, supporting the actuator 100. The lower end of the shaft has a pinion 114 which'intermeshes with rack teeth 115 formed on the actuator 100 by which it is rotated alter nately in opposite directions. All of the shafts 113, being arranged and actuated by the actuator 100 as shown by Fig. 5, causethe cement brushes 106 to move simultaneously to a position above and in engagement with the cement roll when the heel carrier deposits a heel under the nailing mechanism. In this position the brushes remain While the. heel carrier is returning to initial position. The cement roll meanwhile revolvesthereby filling the brushes with cement until the carriage 15, at the end of its return trip, moves the actuator in the opposite direction. The brushes 106 are then moved to their operative positions adjacent the openings 21 of the hoppers.

lVhile this specification and the appended claims refer to removin the lifts from the magazine singly or one at a time, I do not mean thereby to limit the invention to removing only one lift from each magazine, as two or more might be removed from each magazine for a dry or unpasted heel,

without materially changing the construc-' tion offthe machine,.and hence I desire to have those terms construed in the light of this explanation.

H a ring thus explained the nature of my said invention and described a way of constrimting and usin the same, although from said magazines successively Without attempting to set forth all of the" forms in which it may be made, or all of the modes of its use, I declare that What I claim is 1 1.
