MACHINE.

SPE CIPICATION forming part of Letters Patent No. 374,082, dated November 29, 1887.

w Application filed May 29, 1885. Serial No. 167,008. (No model.)

To (ZZZ whom it may concern;

Be it known that I, JoHnPHILLIPs, of St. Louis, in the State of Missouri, a citizen of the United States, have invented a new and use- 5 ful'Improvement in Boot and Shoe Crimping Machines, of which the following is a full,clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The principal object of the invention is to provide a crimping-machine with crimpingjaws which move both vertically and laterally, so that its action upon the upper as it is presented to them shall be as nearly at right angles to the workingedge of the crimping frame or support as desirable.

Another object of the invention is to provide the boot or shoe upper, while it is passing through the crimpingjaws, with a considerable extent of travel, so as .to stretch the leather in the right direction, and get as much corner, as it is termed, as possible without injury to the stock.

It also relates to various features of construction, all of which will be hereinafter'm ore fully described.

Referring to the drawings, Figure 1 repre sents a front elevation of a machine containing my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a plan view thereof. Fig. 4 represents a section upon the line as m of Fig. 1, and a side elevation of the portion of the frame to the left thereof. Fig. 5 is a section upon the line y 3 of Fig. 1. Fig. 6 is a section upon the line z z of Fig. 1. Figs. 7 and 8 are detail views.

A A are the side frames of the machine.

A is an upper cross-girth, and A a lower cross-girth, connecting the two frames.

Bis a cross-head, carrying or supporting the crimping block or form b,which is removable therefrom.

The crosshead is adapted to be vertically reciprocated, and I will hereinafter describe one means of so moving it. This vertical movement of the cross-head moves downward the crimping form or block between the crimping-jaws O between which is arranged a narrow space, into which the crimp- 5o ing form or block with the upper thereon is enable the crimping-form to present uppers of 100 piece, 0 secured to the upper end ofthe wedge.

The side pieces, 0 c, are arranged in relation to the wedge substantially as shown in Fig. 1that 'is, their inner edges, a, bear upon the inclined surfaces 0* of the wedge c.

In other words, the wedge is between these two parts 0 c, and so disposed in relation to them that its movement shall cause them to be separated or brought together, according as the wedge moves, and without breaking joints.

The working-faces of each jaw, comprising the face of the wedge 0 and the faces or side surfaces of the parts a c, are upon the same line, or substantially the same line.

In the drawings I have represented the parts do of the jaws as supported by thecross-piece D, which has the downward and outwardlyextending supports (1, in which are formed dovetail ways or recesses for the support of the parts a c, which have dovetail projections or tongues entering said dovetail recesses. This construction is shown in section in. Fig. 6. I have also shown the wedges vertically movable in relation to the jaws O C, so that their upward movement shall cause the parts 0 c to be moved laterally, or away from each other; So and upon the downward movement of the wedges these parts are returned or moved toward each other by the springs e e, the di-' verging movement of the parts a 0 upon the upward movement of the wedges causing the 4 springs to be compressed. In lieu of this construction, the back sides of the wedges may be provided with grooves parallel with their inclined surfaces for the reception of pins or rolls secured or fastened to the parts 0 c. The c grooves will then act as guides in opening or moving apartand closing or drawing together the parts 0 0, according as the wedge is moved up or down; and I would here remark that instead of moving the wedge vertically it may 5 be stationary and the parts 0' '0 made movable vertically in relation to it.

It is quite essential that the two jaws have a horizontally-yielding movement sufficient to u upper-leather of increased thickness.

varying thickness to the jaws without injury, and I have shown each of the supports'D and sections 0' c of the jaws as arranged to yield horizontally from each other. This construction is shown in Fig. I, whereFF represent the ends of the support D, and fthe holes or apertures in the frame which receives and holds the ends. f are bearing-plates moved by the springs f against the end portions of these pieces and act asa spindle to move them toward each other with a proper degree of pressure, but not sufficient however, to prevent the parts D from being moved away from each other or separated upon the presentation to the jaws of It is of course essential that the guides also have the same yielding movement; and this is pro vided in substantially the same way by means of the spring-held bearing-plates G G, (see Fig. 5,) the bearing resting against the outer surfaces of the wedges c 0, (see Fig. 5,) 9 representing the supports for the springsg",which press against the bearingplates. I may, how ever, use any other equivalent yielding supports for the jaws.

The wedges c are supported by the cross head H, and it and the cross-head B are movable to and from each other by the following means: The cross-head B has secured to each end the rack I), which extends downward to en gage with the teeth of the pinious b operated by the gears Z) upon the shaft 1). The crosshead H has attached at each end the racks h, the teeth of which are adapted to engage with the teeth of the gears I). It is necessary, however, that the cross-head Bcommence to move before the cross-head H and the wedges, in order that the upper may be well within or between the two jaws before the side pieces or sections, 0 c, of the jaws are caused to exert their special action; and in order that this may be accomplished, I have arranged each of the racks h to be held away from the gears If" until the piuions I) have moved the cross-head B sufliciently to bring the crimping-form b between the jaws O U. \Vhen this has been done, the rolls h, carried by the arms h", extending from the racks I), come in contact with the inclines h upon the upper outer surfaces of the racks h, and, riding thereon, draw the racks h inward or toward the racks b and cause the teeth of the racks h to engage the teeth of the gear b This starts the operation of the wedges, and they are moved upward while the crimping-form is yet moving downward, and the sections 0 0 of the jaws are thus caused to move outward and thereby exert upon the portions of the upper against which they are brought in contact a wiping and feeding action from the edge of the crimping-form inward. This movement continues until the entire upper has been subjected to the fitting or crimping manipulations, and the travel of the cross-head and jaws in relation to each other is such that the entire area of the upper is subjected to the crimping and stretching action of the jaws.

The relative movements of the upper crosshead, B, and lower cross-head, II, in relation to each other may be varied,as desired. Upon the end of the respective movements of the cross-heads the machine comes to rest, and is then reversed, and upon the rolls h leaving the inclines If the racks h are automatically drawn from their operating-gears I) by means of the springs and lug 7a, which fits the dove tail or other recess in the racks, which allows or permits the movement of the racks in relation to it. These lugs k are moved outward by the springs k.

I prefer that the surfaces of the jaws be provided with corrugations extending from the central line of the wedge-sections downward; but as this feature is common to other crimping'machines, I make no claim to it.

I would state that in lieu of making the wedges c movable they may be stationary, and the supports D and sections 0 c of the jaws made movable, and in the same time and in the same direction with the crimping block or frame. This construction is advisable when it is desirable to have a slow and long wiping and feeding action of the jaws O O. The frame and the jaws may be moved downward by contact with the cross-head A therewith, or by independent mechanism.

It is not necessary that each set ofjaws C C and each of the wedges 0 have lateral movements in relation to each other, as for certain kinds of work it will answer if only one set be provided with this adjustment.

Having thus fully described myinvention, I claim and desire to secure by Letters Patent of the United States 1. In a crimping-machine, the combination of the crimping form or frame with the crimping-jaws having the laterally-movable sections a c, all substantially as and for the purposes described.

2. In a crimpingmachine, the jaws G 0, having the movable sections a c and the operating-wedges c, all substantially as and for the purposes described.

3. The combination, with the cross-head D, having the supports (1, ofthe jaws having the laterally-movable sections 0, sliding in said supports, the wedges c, and the springs 0, substantially as set forth.

4. In a crimping-machine, the combination of the vertically-movable frame or form Z1, jaws having sections 0 c, and the operatingwedges 0, adapted to have movements in relation to each other, as specified, all substantially as and for the purposes described.

5. The combination of the crimping form or frame I), the jaws O 0, having the movable parts 0 c, and the wedges 0, adapted to be brought into operation after the frame or form I) has moved between the jaws, all substantially as and for the purposes described.

JOHN PHILLIPS.
