SPECIFICATION forming part of Letters Patent No. 629,810, dated August 1 1899.

Application filed April 13, 1898.

ply the outer sole to the lasted shoe and then 1 while the sole is held-in place trim the same, giving to it the shape of the last, a suitable guide working usually in the space between the junction of the welt and the upper while the surplus material of the sole is being removed from a point back of the shank-about the ball and toe, thus shaping the sole exactly in conformity to the shape of the last. Frequently the sole while being so trimmed or shaped is channeled. lhe heel end of the sole, called the heel-seat, is not, however, trimmed to shape in this usualmachine for the reason that in the absenceof the welt, which does not extend about the heel-seat,

the guide used would not find a proper bearin g, and consequently the heel-seat would not betrimmed correctly and has to be done at a subsequent operation.

I have devised a novel machine for trimming the heel-seat end of the sole, thus fully preparing the sole for the subsequent steps of attaching the sole to the welt and applying the heel to the heel-seat end of the sole.

My novel machine has a pattern-plate, it in this instance of my invention being represented as stationary, said pattern-plate being of the shape which it is desired to give to the heel-seat end of the sole. The heel-seat end sustained on this pattern-plate is acted upon by a clamp interposed between the upper and inner sole and the inner side of the outer sole the edge of which is to betrimmed, said clamp being preferably operated automatically to efiect the firm clamping of the stock in one movement of the" bladecarrier, to be describedthat is, that part of its stroke when the heel-seat is being trimmed-the clamp preferably rising immediately after the trimming or rounding has been efiected and while the carrier and blade are being returned into Serial No. 677,'52. (No modem their'nornial orstarting position. This clamp will preferably be provided atits under side with aprojection which may approximate in shape the shape of the pattern, such projecwhich is free to slide in a guideway occupying a position substantially parallel with a line which would divide the sole from end to end, said block deriving its movement to and fro in said guideway by or through an arm pivotally mounted on or with relation to said block, said arm deriving its motion from a second arm which is moved to and fro in the arc of a circle, the two arms being shown as made movable about different centers and as being connected loosely one with the other by a pin-and-slot or. other'loose connection.

The lever upon which is mounted the carrier referred to is provided at one end with a suitable roller or other stud which enters an irregular cam-groove in a plate, preferably the same plate which is provided with the guideway referred to, in which moves the slide-block carrying the lever hereinbefore mentioned. This plate will also have, preferably, a suitable groove to receive a projection of the pattern-plate on which rests the end of the sole to be trimmed or rounded for the production of the heel-seat.

The carrier is so mounted on the lever referred to that it may slide back and forth under the control of a suitable spring or springs to thereby enable the carrier to adapt itself to difierent sizes of patterns according to the size of the shoe the heel-seat of which is to be rounded.

Figure 1, in vertical section, shows a machine embodying myinvention in one form, said machine being partially broken out to save space on the drawings. Fig. l is annuder side view of the clamp. Fig. 2 is a top view thereof on a smaller scale. Fig. 2 is a right-hand end view of some of the parts shown in Fig. 2. Fig. 3 is a detail in top view, the pattern, clamp, and counter-guide being omitted; and Fig. 4: shows the bed-plate as transparent, with the devices underneath, chiefly in dotted lines, for moving one of the arms referred to for imparting motion to the lever having the blade-carrier.

The framework of the machine consists, essentially, of suitable legs A, having mounted upon them a top plate A, above which is supported in suitable manner a-bed-plate B, a standard B being erected on the bed-plate. The bed-plate has connected to it at one end, as by a screw-b, a stand B on which rests a plate 0, said plate being held in position by a suitable screw 0. This plate Chas (see Fig. 2) an irregular cam-groove c and it also has a guideway 0 (Shown in Figs. 1 and 3 by full lines.) The opposite end of the plate C- is suitablysustained rigidly with relation to the stand B" and the bed-plate.

The stand B has a suitable guideway Z), preferably dovetailed in cross-section, in which fits to slide a dovetailed projection Z2 of a clamp B the under side of said clamp being cut away, preferably, to leave a projection I), (seeFigs. 1 and 1,) the outlines of said projection approximatingin shape the end of the pattern D and when in operative .position falling preferably with the'face of said projection inside the edge of the pattern. The upper side of the clamp is preferably tapered on the lines 0 so that the said clamp may be readily inserted between the upper of the shoe (designated by dotted lines e) and the heel-seat end 6 of the sole of the shoe, said sole, it being understood, being at such time secured in some way to the lasted shoe on the last in order that the heel-seat end may be trimmed to the desired shape-a shape determined by the pattern D. This pattern in this instance of my invention has a suitable dovetailed or other shaped projection, as d, which enters a dovetailed groove (see Fig. 2) in the plate 0, preferably the same screw 0 hereinbefore described, acting, when turned in fully, to clamp and retain the said patternplate in its working position.

The pattern-plates used will be of dilferent sizes, according to the particular size of the heel-seat end which is to be trimmed, and one pattern-plate may be readily substituted for another one of the proper size, as desired.

The bed-plate B has a suitable hole for a short shaft 6 having applied toits lower end a pinion a which is engaged in this instance of my invention by the teeth of a sector-lever e pivoted at 6 said sector-lever being shown as slotted, as at a, said slot being entered by a crank 6 carried by a disk a fast on the upper end of a shaft 6 provided, as represented, with a suitable beveled gear 6 which is engaged and rotated by a beveled gear 6 fast on a shaft 8 which derives its motion from any usual or suitable automatic clutch, so that said clutch controlled by a treadle in groove f, in which may enter a roller or other stud f, extended from a rod f attached to an arm f fixed to a rock-shaft f, mounted in the stand B, said rock-shaft having a sec- .ond arm f which is'suitably joined'to an ear of the clamp B The cam-groove f referred to is of such shape that when the machineis in its stopped position the said clamp will occupy its elevated position, the cam immediately after the machine is started acting to depress the clamp and holding it depressed substantially throughout the trimming or rounding operation, at which time the cam will act to again effect the raising of the clamp to release the heal-seat end of the sole.

The shaft 6 has suitably connected to its upper end (see Fig. 1) an arm g, herein represented as provided With a slot g, which is entered by a pin or stud g of a second arm h, connected with a rocking stud 7L, extended through a block 72?, mounted to slide to and fro in the guideway 0 of the plate G hereinbefore described. The upper end of this rocking stud It has suitably pinned to it a lever 72 provided at one end with a roller or other stud 7L3, which enters the cam-groove c of the plate 0. This lever at its opposite end is slotted, as at 2, to receive a carriage 3, on which is pivoted at 4 a suitable carrier 5, having at'its end next the pattern plate suitable rollers 7 to-contact with the edge of said pat.- tern-plate, said carrier having a groove in which is fixed in an adjustable manner by a suitable set-screw the shank of a blade 8 the blade used to round or trim the heel-seat end 6 of the sole. A suitable spring 10, located in the lever 7L2 and acting against a portion of the carriage 3, serves normally to keep the rolls of said carrier in contact with the edge of the pattern, the spring yielding more or less as the carrier mounted upon the lever is moved about the pattern in the trimming of the heel-seat end of the sole.

Figs. 2 and 3 show the carrier and its blade in their normal position, and while the carrier is being moved in the direction of the arrow Fig. 23 around tothe point 13 (see Fig. 3) of the pattern the clamp hereinbefore referred to will act to hold the heel-seat end of the sole firmly pressedagainst the pattern; but soon or immediately after the arrival of the blade in the position'l the said clamp may be raised while the carrier is being returned into its normal position ready to again act upon and trim and round another heel- ICC seat, and during this return movement of the carrier and blade the trimmed or rounded heel-seat is'withdrawn with the shoe from themachine.

When the shoe is being put into position to have the heel-seat end of the sole trimmed, the counter of said shoe or the upper at a point surrounding the usual counter is forced back into the counter-guide m, shown as composed of two bent spring-arms. Preferably the acting end of the clamp will be out out, leaving it of a forked or U shape, as in Fig. 1.

Believing myself to be the first to devise a machine having a clampto act upon the heelseat end of the sole after the sole is applied at its fore part to a lasted boot or shoe to thereby clamp the said heel-seat end transversely and firmly upon a pattern-plate while the heel-seat end is being trimmed or rounded to shape, this invention is not limited to the precise form or shape of clamp or to the exact means described for actuating said clamp, as it will be obvious to those skilled in the art that the construction and shape of the clamp and its actuating'means might be variously modified with only the skill of the mechanic and Without invention.

It will be noticed that the short shaft 6 and the short shaft h occupy different centers, and the provision of allowing the shaft h to move to and fro in the guideway While the lever upon which is mounted the carrier and its blade is being moved about the pattern enables the carrier and blade to follow correctly the pattern, which is not in the same curved line, but is in varyinglines or contour, according to the shape to be given to the heel-seat end of the sole.

In this invention the clamp made the subject of this claim does not act against the edge of the sole at its heel-seat end, but said clampis so shaped that it may be interposed between the upper side of the sole as yet unattached to the upper at its heel-seat end, said clamp acting upon the upper side of the sole next the lasted upper and clamping it transversely against the face of the patternplate, leaving the edge of the outer sole to be rounded projecting between said clamp and pattern-plate, so that the blade, actuated by the carrier, may traverse about and trim the heel-seat end while itis clamped transversely or in the direction of the thickness of the sole between said clamp and the pattern-plate.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, ise 1.
