CHANNEL-FLAP-LAYING MACHINE.

SIEGIFICATION forming part of Letters Patent No. 538,637, dated April 30, 1895. Application filed July 27, 1894. Serial No. 518,692. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM L. BARRELL, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Ohannel-Flap-Laying Machines, of which the following description, in connection with the accompanyingdrawings,isaspecification,like letters and numerals on the drawings representing like parts.

This invention has for its object theproduction of a machine to lay the channel flap in the sole of a shoe preparatory to the leveling or beating out of the sole, and the mechanism hereinafter described is particularly adapted for use in connection with the sole leveling machine shown in United States Patent No. 522,776, granted to me the 10th day of July, 1894, to which reference maybe had. In said patent a series of supports is successively brought into position to cooperate with a former, said supports being preferably arranged for rights and lofts alternately, the former for each being automatically brought into position to co-operate with its particular support, means being provided to act upon the interior of the shoe to raise it from the support when leveled, and to push it partially off, so that the operator can readily remove it with one hand.

The channel flap laying mechanism which forms the subject of this invention is so applied to the leveling machine shown in said,

patentthat the shoe to be leveled will, after having been placed upon a support by the operator, be moved into position to have the channel flap laid back into its original position in the channel with sufficient force to insure its retention by the cement with which the channel has been filled after the shoe has been sewed. After the channel flap has been laid, the shoe is moved into position to have the sole leveled or compressed.

My invention consists essentially in a rotary beater adapted to bear upon the sole and lay the flap, aswinging support for the beater, mechanism to actuate said support and controlling devices to govern the said actuating mechanism, whereby the beater follows and bears against the upper side of the flap and lays it in the channel, substantially as will be described.

Other featuresof my invention will be hereinafter described and particularly pointed out in the claims.

Figure 1 represents in elevation and partly broken out the rearside of a sole-leveling machine, as shown in the patent referred to, with my channel-flap-laying mechanism en1- bodied therein. Fig. 2 is a vertical sectional view thereof, taken on the line 0000, Fig. 1, and looking toward the left. Fig. 2 is a detailto be described, taken below the line y, Fig. 2. Fig. 3 is a plan view, partly in section, taken below the line or m, Fig. 2. Fig. 4t is a sectional detail of the controlling-cams, taken on the line y y, Fig. 2; and Fig. 5 is a detail to be referred to.

The frame A, braces A and A head A, bevel gear a small bevel gear a engaged thereby and fast on a shaft 0. supported in a bracket a secured to the brace A the main shaft D having loose thereon belt pulleys d, d, the pinion (1 fast to the pulley d, and engaging a large gear 01 fast on an auxiliary shaft D, see Fig. 2, and the pinion d fast thereon, the carrier, its shoe supports, ejectors and actuator therefor, the knock-off, the formers and so much of the actuating mechanism as is herein shown, are and maybe as in said United States Patent- No. 522,776, referred to, to which reference may be had, the same parts being lettered herein as shown in the said patent.

Referring to Fig. 1 of the drawings, the bevel gear a is made as a ring, having its arms or spokes 5 extended beyond the plane of its upper side, to accommodate a gear a fast on the short shaft a, to be engaged and rotated intermittingly by a segment gear 0 fast on the main or driving shaft D. See Figs. 1 and 3. This segment gear O is in construction and function the counterpart of the segment gear 0 in the patent referred to, and the teeth 1 c on one-quarter of its circumference are suf- In order to make room for the controlling cams of the channel flap laying mechanismJ have bodily moved, as it were, the said segment gear, toward the center of the machine, and have built it out at o Fig. 1, far enough to carry the periphery 0' beyond the gear a said periphery being cut away opposite the teeth 0 and slightly beyond the end ones, as at c the said periphery 0' being in the path of an escapement c secured to the shaft a and movable with the pinion a As in the patent referred to, the curved face of the escapement rests on the periphery c and holds the pinion a from rotating until the teeth a are brought into engagement therewith, at such time the escapement c turning with the shafta and entering the cut-away portion 0 of the periphery. A segmental gear 0 see Figs. 1, 2 and 3, is secured to the peripheral portion a of the segment gear O and is provided with just enough teeth to rotate a gear 0 through one-half of a revolution, said gear being fast; on a sleeve 0 to be described, loose on the shaft D, best shown in Fig. 3. The pinion (Z engages the large gear (1 on the auxiliary shaft D, and a pinion of fast thereon engages a gear (1 fast on the driving shaft D, as shown in Fig. 3, whereby the speed of the driving shaft is reduced without reducing the speed of the driving belt.

Referring now to Figs. 1, 2 and 5, I have secured to the under side of the brace A at the rear of the machine and at oneside a bracket 1), longitudinally slotted at b and provided with bearings 19 for'studs or shafts 12 having thereon idlers b for a purpose to be described. The bracket 1) is interiorly recessed to receive therein a casting b adapted to slide longitudinally in the bracket, and held in adjusted position by a suitable set screw extended through the slot 1), the outerend of the casting havingformed thereon ears 127 to receive between them a lug b of a fulcrum block b, held in place by and adapted to swing laterally on a vertical pivot pin Z2 passing through said lugs and car.

As best shown in Fig. 2, the fulcrum block L is vertically slotted at b to receive the shank of a fulcrum pin or pivot 19 extended through a longitudinal slot at in a swinging support, shown as a lever n, said lever being free to swing about said fulcrum pin in a vertical plane. Raising or lowering the fulcrum pin b raises or lowers the pivot about which the lever 11 swings and so varies the relative throw of its ends.

The swinging support orlevern is enlarged at its extremities, as at n and M, and recessed to respectively receive therein slide bars 11 and n, the outer ends of said bars being provided upon oneof their sides with rack teeth 02, and 01 in engagement with like gears 0 and 7 fast on a shaft 8 extended through bearings 2 and 3 on the extremities of the lever 71, and also through an intermediate bearing 5 on the fulcrum block b, whereby motion of one slide bar in one or the other direction in its support will be communicated to the other slide bar simultaneously. The inner end of the slide bar n is prolonged and downturned as at n", and is provided at its end with a suitable roll 01, to enter and be engaged by a cam groove o formed in the inner face of a traverse cam 0 secured to or forming a part of a hub O keyed to the main or driving shaft D and longitudinally movable thereon.

The cam 0, as best shown in Figs. 3 and 4, is so shaped that the cam groove 0 is not in a single plane, but a portion of the cam at o and also the groove therein, are at right angles to the longitudinal axis of the shaft D, so that no lateral movement will beimparted to the end a of the slide bar 01 while the roll 91" traverses that portion or dwell of the cam. A second cam 19 having a cam groove 1) thereon, is located on the hub Oadjacent the cam o, the side of the cam 12 nearest thereto being suitably shaped to retain the end it and its roll a in the cam groove 0 during the rotation of the cams.

It will be seen that the groovep is formed in the side of the cam 19 farthest from the cam 0, one of said grooves controlling the movement of the slide bar 01 and its co-operating parts for a right shoe, the other groove controlling the movement for the left shoe, the cam 19 having a break 0 therein, see dotted lines Fig. 2, whereby the roll 92 can pass from one to the other cam groove when the change is to be made from a right to a left shoe, or vice versa. A third cam ,q is shown adjacent the cam 19, its inner side forming a guard to retain the roll 91 in place when traversing the cam groove 1) The cams p and q are provided respectively with dwell portions 19 and (1 corresponding with the dwell 0 as best shown in Fig. 3, and the break 0 in the center cam is located in such dwell portion. Regarding the center of the shaft, the grooves 0 and p are so shaped that the beater roll, to be described, will always be exactlyover that portion of the channel flap of the shoe sole upon which it is acting, the shape of the groove 19" being shown in dotted lines Fig. 2, the parts being in pos'ition to move the beater roll along from the center of the toe down one sideand to the heel.

The dwell portions 0 J aud (1 of the cams take up one-quarter of the circumference of the respective cams, the beater roll being held from bodily movement at such time, while the shoe just completed is removed by the operation of the leveling mechanism, as described in the patent referred to, and a new shoe is presented to be treated, the throw of the lever a on its vertical pivot 0 back and forth taking place through the remaining three quarters of the circumferences of the traverse cams as they rotate. While the roll n" is stationary the cams are moved bodily on and in the direction of the length of the shaft D by means of a yoke lever 20, pivoted at 21, see Fig. 3, one end of which engages the hub O,

as shown, the other end of the said lever carrying a roll 22, shown in dotted lines Fig. 3, in engagement with a cam 23 fast on the sleeve 0 loose on the shaft D.

In the rotation of the shaft D the toothed segment 0 is brought into engagement with the gear a on the sleeve 0 and rotates the latter sufliciently to swing the yoke lever 20 to the right or left, as the case may be, just as the break 0 inthe cam 19, arrives opposite the roll a", which is in one or other of the cam grooves 0 or p, and the hub O is thereby moved to bring the said roll into the other cam groove, so that the mechanism is ready to operate on the next shoe.

Referring now to Figs. 1 and 2, the slidebar n is extended at its inner end to form an arm 0 having bearings r fora vertical sleeve 1" rotatably mounted therein, and maintained in position by an annular flange or plate r see also Fig. 2, fast thereon, and adapted to rest on the top of the upper bearing 0", a slight vertical movement of the sleeve being permitted. A shaft 1' has its bearing in and projects beyond the sleeve T and a bevel gear 4' is seen red to its lower end to engage a bevel gear 3' on the inner face of a beater s, herein shown as a roll mounted to rotate on a stud 0 projecting from the sleeve T In practice I preferably make the beater roll about three inches in diameter and about an inch face, the latter having a saw-like or ribbed surface.

The upper end of the shaft r above the flange or plate r has fast thereon a whirl r about which is passed an endless band or cord 8X, which is carried over idlers s on the arm 0 and thence around the idlers b to a driving pulley 3 supported on a shaft 3 having its bearings in a bracket or hanger s and rotated by a gear 5 in engagement with the gear d, as best shown in Fig. 2.

By means of the band s and intermediate connections the beater rolls is rotated at a high rate of speed and always in the same direction.

The particular shape of the cam grooves 0' and 19 control the lateral movement of the beater roll 8 in its movement from the heel to the toe and back on the other side of the shoe to the heel, swinging the lever n and all its parts asa whole about the fulcrum b, it being remembered that one cam groove is for a right and the other for a left shoe.

Inasmuch as shoes of different sizes vary in Width the lateral throw of the roll 8 must be greater in some instances than in others, and to provide for this variation the fulcrum 17 of the lever n is made vertically adjustable, lowering of said fulcrum increasing the throw of the beater roll, and vice versa.

The plane of the traverse or controlling cams govern the movement of the beater roll from heel to toe of a shoe, and to provide means for adjusting the length of such movement I have made the casting b adjustable in the bracket b, as described. When the said casting is moved to the'left, Fig. 2, it carries with it the fulcrum block b", lever n, and shaft 8, and such movement of the shaft causes the gear 7 to rotate as it travels over the rack teeth n of the slide-bar 72 This rotation of the shaft 8 in turn causes the gear 6 to travel over the rack n, so that the slidebar n remains stationary, and the greater the movement of the lever n to the left or outwardly, the greater will be the length of the lever arm of the slide-bar n or in other words the greater the distance between perpendiculars through the pivot pin b and the roll n It follows that the shorter the lever arm n the greater will be the swing of the lever n, and the longer the travel of the beater roll in the direction of the length of the shoe, and as the length of shoes vary the travel of the beater roll is adjusted to accord therewith, by increasing or decreasing the length of the lever arm n of the slide-bar. The throw of the beater roll is greater than the lateral movement of the roll a at all times, however, for the distance between the beater roll 3 and pivot 19 is always greater than the distance between said pin and the roll a", measured between perpendiculars.

As difierent sizes of shoes have a certain ratio between the length and width, I will provide suitable scales on the fulcrum block b and the bracket 6, so arranged that when a given size of shoe is being operated upon, the operator will only have to set the centers of the set screws or clamps b and Z9 opposite the proper graduations on their respective scales, and the mechanism will operate properly. The rotation of the beater roll sis in 'the direction of the arrow 50, Fig. 1, or from the center of the shoe sole outward toward its edge, so that the action of the roll upon the channel flap is from its base to its free edge, and in order to always maintain such rotation relative to the center of the shoe, to gradually lay the channel flap, it is necessary that the support for the beaterroll be turned on its axis at the heel and toe of the shoe.

The annular flange or plate W has four pins or projections r on its upper side, to be engaged by lugs w, 10 on the adjacent side of a rod to resting on said flange and pivotally connected to a bell-crank leverw on the arm 4", the rod being held in engagement with the pins 0" by a spring 8 Figs. 2 and 2. When the rod or actuator to is moved by the lever 10 in the direction of the arrow 40, the lug w, engaging one of the pins 1", will rotate the flange r and its attached sleeve r through one-quarter of a revolution, whereupon the lug to will come into engagement with the next pin r and move it to complete the turn, the pin engaged by lug to having been moved out of-engagement therewith by the described movement of the flange. At the end of the throwof the actuator to to the right the pin engaged by the lug 10 will have been moved through one hundred and eighty degrees from its original position,and the next succeeding IIO pin will be in position to be engaged by the lug '20 upon its. next forward movement, which takes place after its return to its original position by means to be described. Each movement of the actuator to the right will thus turn the sleeve 1' and consequently the beater roll 8' supported thereby, through an arc of one hundred and eighty degrees, a de tent, herein shown as a spring pin 8 bearing against the sleeve and preventing by its friction accidental rotation of the sleeve. The actuator is. drawn toward the path of the pins r in a yielding manner by suitable means, herein shown as a spring 3 secured at one end to the actuatorw, and at the other end to the arm 4, the backs of the lugs wand 10 being curved to easily ride over the pin in its movement opposite the arrow 40.

Beginning at the heel of the shoe, thechannel flap of which is to be laid, the axis of the beater roll is substantially parallel to themedian line of the sole, and such position is maintained until nearing the toe, when the turning begins, and when the center of the toe is reached the beater roll axis is at right angles to the median line. Continuing around the other side of the toe the roll is turned ninety degrees more and the flap on that side of the sole is laid. When the heel is reached the roll is turned through one hundred and eighty degrees until in its original position, to start a new shoe. These changes are accomplished by means of the peripheries of the cams p and q acting on a suitable roll to carried by a link 10 pivotally connected at 10 to one arm of an elbow lever to, the other arm of said lever being connected by a link 20 to the elbow lever 10 as clearly shown in Fig. 2, the cam peripheries being shaped according to the particular style of shoe to be treated. The elbow lever to is pivoted at 20 to the slide-bar 71 and to the more securely connect the link 10 to and to move bodily with said slide-bar, its outer end is connected at w by a short link to to an arm w erected on the outer extremity of the slide-bar, the length of said link between centers being equal to the distance between the pivotal points to and w As the controlling mechanism described moves laterally with the lever n and its attached parts, the roll to would leave the periphery of the traverse cams at the points of greatest throw, and to obviate this the raised portions 19 p and g (f, on said cams are bent out of the plane of the cams, as shown in Figs. 1 and 3, so that the roll to may travel thereon, and yetsuch raised portions of the cams will notinterfere with the lever n Referring to Fig. 2, it will be seen that the beater roll at the toe of the shoe, while the portions 19 g turn it at the heel, and the shape of the toe controlling portions will be It is unnecessary to further describethe op eration of the apparatus in View of the foregoing detailed description, the channel flap of one shoe after another being laid rapidly and accurately prior to the presentation of the shoe to the former tolevelthe sole thereof.
