FREDERICK H. PERRY, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

SOLE-FITTING MAGHINE.

To all whom it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Fitting Machines; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for use in the manufacture of boots and shoes and more particularly to such machines for op erating upon the marginal portions of soles provided with a marginal lip which may include a reinforcing layer of fabric.

There are several operations performed on the marginal portion of a channeled insole in preparing it for the subsequent welt sewing operation. These include forming or molding the lip to a proper shape to be acted upon by the welt sewing instrumentalities and, on the Economy type of reinforced insoles. trimming the canvas proiecting above the top edge of the lip. These operations are well known in the art of shoe making and various machines have been devised for performing them.

The object of the present invention is to improve and simplify the construction and mode of operation of machines of the character described. To the accomplishment of this object. and such others as may hereinafter appear, the invention comprises the features and combinations of parts which are hereinafter described and particularly pointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of the machine;

Fig. 2 is a longitudinal section of certain parts of the machine looking in the opposite direction from Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 1; I

Fig. 4 is a section on the line 4.4 of Fig. 2; and

Fig. 5 is a detail plan of the work engaging tools.

In the illustrated embodiment of the invention the sole to be operated upon is sunported by a work table 10 which coacts with Specification of Letters Patent.

Serial No. 215,157.

a feed wheel 12 to grip the feather and feed the work to the tools. The work table and feed wheel are connected for rotation by gears 14 and 16 mounted on separate vertically arranged shafts. The feed wheel is driven by a worm gear 18 which meshes with a worm 20 on a driving shaft 22 which may be driven by any suitable pulley connections (not shown). The shaft 22 also carries an eccentric 24 which acts through a block 26 to reciprocate a fork 28 pivotally mounted on a stud 30 in the machine frame. The fork is provided with an integral arm 32 which actuates the lip hammer 3 to impart a succession of blows to the outside of the lip as the insole is fed past the hammer. In so far as has been described, the construction of the machine may be and preftrably is identical with that shown in the United States patent to Hadaway No. 638,010., granted November 28, 1899.

In the present machine the inside lip supporting tool or anvil 36 (Fig. 2), against which the hammer compresses and molds the lip, is formed. on the lower end of a rod 38 which is rigidly secured, by a nut 40 in a bracket 42. The bracket is held in adjusted position on a casting 4:4- by a clamp screw 50 and. a. set screw 52 by which longitudinal and vertical adjustment of the anvil may be obtained. The casting 4411s, in effect a part of the machine frame d6, it being secured thereto by screws 48 (dotted lines in Fig. 2).

Provision is made for imparting a yielding blow to the hammer in order that the compression of the lip may not be so great as'to injure it, particularly when a thick portion of the lip is encountered. To this end the connection between the hammer operating arm 32 and the hammer 34 comprises a stud 54: (Figs. 2 andd) fixed in the arm and passing through a slot 56 in one end of a link 58. the other end of which is pivotally connected by a pin 62 with the hammer carrying slide 60. The ends of the links are slotted so as to embrace the ends of a spring 6 one end of which bears against the stud 54 and the other against the end of the slide 60. The hammer 34: is fastened to theslide by a screw 61. By this construction the hammer is normally held in advanced position with relation to thearm 32. but when the hammer has compressed the lip with sufiicient force to overcome the spring 64',

the slot 56' permits the arm to complete its normal movement without exerting undue, pressure on the work.

The canvas or other reinforcing material is trimmed to a uniform height above the sole by a reciprocating knife 66 which 1s located above the hammer 34 and cooperates with the anvil 36 to produce a shearing cut. The anvil 36 is preferably made in two parts, the upper part consisting of a hardened steel washer or shearing disk 68 which is clamped between the lower part 36 and the bracket 42 by the nut 40. When the portion of the disk in operative relation with the knife 66 has become dull, the nut 40 may be loosened and the disk may be partially rotated to present a new portion of the edge to the knife. hen the entire upper periphery has been used. the disk may be reversed so as to use the opposite side as a shearing surface. This construction avoids the necessity of sharpening the shearing edgeof the anvil, as dull disks may be discarded and new ones substituted without disturbing the adjusted position of the anvil.

If the leather lip has not been trimmed previously it also may be trimmed by the knife 66. The shank of the knife is offset (see Fig. 5) and is clamped in a dovetailed slot in the forward endof a slide 70 (Fig. 1) by a screw 72 which permits adjustment of the knife toward and from the anvil 36. The slide 76 is mounted in a way having the usual! gib 74 in an adjustable knife carrier 76- (Figs 1 and 3). The rear end of the slide 70' is slotted in one face to embrace a bloolt 78 loosely mounted on a pin 80 projecting from the arm 32. By this construc tion the hammer 34' and the knife 66 are actuated simultaneously by the eccentric 24, but whil'e the knife has a positive reciprocation, the hammer has a variable movement because of the yielding connection heretofore described.

lmife carrier 76 is pivotally mounted in the frame 48- by a stud 82, about which it may adjusted to raise or lower the knife by the manipulation of screws 84 1) threaded through a ledge 86 projecting from the casting 44-. To obtain a clean severance of the canvas, the vertical relation between the knife 66 and the upper surfaee' 68 of the anvil must be accurate. The anvil must also be cap'abie of adjustment and convenient to remove to substitute others' 'toaccommodate different classes of work. The construction described permits convenient adjustment of both these pbrtsso that a clean out will always be obtained'.

. While the various features of the prefer-red form of the invention have been described as applied toa machine for operatmg upon reinforced insoles of the Economy t pe, it will be apparent to those skilled in tie art that certain features of the invention may advantageously be employed for operating upon reinforced insoles of other types, or upon all leather insoles.
