LEATHER FORMING OR MOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 564,641, clated July 28, 1896.

Application filed October 16,1895.

To aZZ whom it may concern.-

Be it known that we, AUSTIN E. PERRY, of Wakefield, in the county of Middlesex, and XVILLIAIWI GORDON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Leather Forming or Molding Machines, of which the following is a specification.

This invention relates to machines for molding leather by pressure between two opposed surfaces, and it has particular'reference to machines for making outer soles of springheel boots and shoes, such soles being oifset to form an incline between the heel and shank portions of the sole in amanner well understood.

The invention has for its object to provide an improved machine adapted to quickly and effectively form the ofiset or inclined breast on a sole; and it consists in the improvements which we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of our improved machine. Fig. 2 represents a top plan View. Fig. 3 represents an end elevation. Fig. 4 represents a section on line 4 4 of Fig. 2. Fig. 5 represents a partial elevation and partial section of portions of the machine, showing the operation of molding the sole. Fig. 6 represents a View similar to Fig. 5, the scoring device being omitted. Fig. 7 represents a sectional view of a portion of a sole as formed by the improved machine. Fig. 8 represents a modification.

The same letters of reference indicate the same parts in all the figures.

In the drawings, ct represents a supportingframe having fixed bearings for a shaft b, to which is affixed a bed-roll c. Said bed-rollhas two beveled peripheral surfaces 2 3, formin g a groove, and a cylindrical peripheral surface at'at one side of said groove.

cl represents a yoke or frame which is mounted to oscillate upon pivots or centers (1 d and is movable toward and from the shaft 6 and bed-roll c. The yoke 01 is provided with bearings in which is journaled a shaft e, to which is'affixed an indenting-roll f, the periphery of Serial No. 565,838- (No model.)

which has a milled or corrugated angular edge coinciding with the bottom of the groove in the bed-roll, the said indenting-roll being placed directly over the bed-roll, so that the two are adapted to cooperate in bending a sole 3 in the manner shown in Figs. 5 and 6. The swinging movement of the yoke 61 enables the indenting-roll to be adjusted toward and .indicated by the'arrows in Fig. 3 by any suitable means, such as a driving-shaft h, apinion 71 thereon, a gear j on the shaft b, meshing with said pinion, and intermeshing gears k, affixed respectively to the shafts b and e. m represents a circular knife or scoringdisk which is located beside the indenting-- roll and occupies such position that it cuts into or scores the upper surface of the sole along a line over the cylindrical portion 4 of, the bed-roll, said portion supporting the leather under the pressure of the scoringblade. ,7 1

The object of the scoring-blade is to cuta transverse incision s in the upper surface of the sole at one edge of the incline or offset 5 formed by the conjoint action of therolls c and f, as shown in Fig. 5, said incision enabling the sole to be readily bent to form a reentrant angle at the upper edge of the breast or incline s on the under side of the sole. The scoring-disk m is attached to a holder m, which is mounted to rotate upon a stud m secured to a vertically-adj ustable slide or block m the stud m being horizontally adjustable in said block, so that the scoring-disk can be adjusted horizontally toward and from the indenting-roll to vary the distance between the incisions and the bottom of the groove formed in the sole by the indenting-roll, and also adjusted vertically to vary the depth of the incision s or to accommodate the scoring-disk to soles of different thickness. The horizontal adjustment of the scoring-disk is effected by means of a screw-thread connection between the stud 'm and the slide m a check-nut m being employed to hold said stud at any point to which it may be horizontally adjusted. The Vertical adjustment of the scoring-disk is effected by means of an adjusting-screw m, having a screw-thread connection with the yoke d and journaled in the slide m so that when the screw is raised or lowered by its rotation it will impart a similar movement to the slide.

In order to provide for adjustment of the scoring-disk independently of the indentingroll, we connect said disk and roll by means of a pin 71, affixed to the disk and entering a slot 0 in the indenting-roll, said pin and slot constituting a self-adjusting connection "which maintains an operative engagement between the roll and disk, so that the disk is positively rotated by the roll and permits independent adjustment of either the disk or the I roll.

'13 represents a horizontally-movable slide or sole-carrier, which is movable in guides at right angles with the shafts of the rolls 0 f, the carrier being arranged at such height that a sole '8, resting onits upper surface, will, by the movement of the carrier toward the left in Fig. 3, be presented to the rolls, which will grasp the sole and remove it from the carrier,

carrier, as indicatedin dotted lines in Fig. 3, when it has passed the meeting points of the V rolls 0 and f, the gage 19 being permitted to thus drop by a depression 12 on the supporting-frame. The gage p is used when the soles of right boots and shoes are being treated, the onter edge of the solebearing against the gage 10 as indicated in full lines in Fig. During the inward movement of the carrier by the operator the gage 19 remains in its operative position until the sole has been inserted between the rolls and then drops to the position shown in dotted lines just as the rolls commence to'grasp and move the sole forward, so that the gage does not oppose the forward movement of the sole by the rolls.

cated in dotted lines in Fig. 2, and is pushed onward by said gage until the sole is grasped and carried forward by the rolls, the gage p dropping to permit the sole to be moved off from the carrier by the rolls.

q represents a heel gage, which is adjust- T ably mounted upon the carrier and bears on the end of the heel of the sole 8. Said gage has a graduated plate g, which cooperates with a finger or pointer g on the supportingframe in indicating the position of the gage q for soles of difierent sizes.

The operation of the machine is as follows: In treating a right sole the operator places the sole upon the carrier, as indicated in full lines in Fig. 2, and pushes the carrier inwardly until the sole-is grasped by the rolls, the gage p at the same time dropping. The

rolls grasp the sole and move it onward, in-

denting the same, as shown in Fig. 5, the heel end of the sole tipping upwardly. The sole is delivered by the rolls at the back of the machine. When a left sole is being operated on, the operation is the same as above described, excepting' that the outer edge of the 'sole is placed against the fixed gage 19 It will be seen that by the described apparatus soles "can be quickly molded and-adapted foruse on spring-heel boots and shoes.

We do not limit ourselves to the use of the scoring-disk, as the rolls '0 and f, used without said disk, as indicated in Fig. 6, will mold or ofiset the sole, though not as perfectly as when the disk is used. I

It is obvious that the machine may be adapted to other uses without departing from the spirit of the invention.

We do not limit ourselves to the particular details of construction here shown, and the same may be modified in various particulars. For instance, instead of providing two gages for the sole-carrier, a single gage may be used for both right and left soles, as in the modification shown in Fig. 8, in which 1) repre sents a gage pivoted at p to the carrier and adapted to occupy a position parallel with the shafts of the rolls for left soles, as shown in dotted lines, and to be placed diagonally or oblique for action on right soles, as shown in full lines, said gage being secured in either position by means of a clamping-nut p We 'claim- 1. In a machine of the character specified, the combination of a groovedbed-roll having a peripheral 'surface'at one side of the groove, an indenting-roll arranged to enter the groove of the bed-roll, and a rotary scoring-disk located beside the indenting-roll in position to cooperate with the peripheral surface of "the latter. g

2. In a machine of the character specified, the combination of agrooved bed-roll having a peripheral surface at one-side o'f thegroo've,

, of the bed-roll, a rotary scoring-disk located When a left sole 1s being treated, its outer edge rests against the fixed gage 19 as indi- T beside the indenting-roll in position to 006p eratewith the peripheral-surface of the latter,

and a connection between the indenting-roll and disk, whereby one is caused to rotate with the other.

3. In a machine "of the character specified,

. the combination of a grooved bed-roll, an in denting-roll arranged to cooperate with the bed-roll, scoring-disk located beside themdenting-roll, a support for said disk adjustable independently of the indenting-roll, and means for adjusting and holding said support.
