UNITED STATES PATENT OFFICE.
JOSEPH O. LOOKETT, OF BOSTON, ASSIGNOR TO CHARLES S. PIERCE, OF BROOKTON, MASSACHUSETTS.
CRlMPlNG-MACHINE.
SPECIFICATION forming part of Letters Patent No. 485,204, dated November 1, 1892.
Application filed September 18 1891. Serial No. 4 4 (N0 model-J To all whom it may concern:
Be it known that I, JOSEPH O. LOCKETT, of Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Crimping-Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation of my improved crimping-machine; Fig. 2, a front elevation of the same, partly in section, the standard of body being removed; Fig. 3, a horizontal section taken on line a; 00 in Fig. 1; Fig. 4, a face View of one of the jaws, and Fig. 5 a transverse section of the same.
Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.
My invention relates especially to machines for crimping the uppers of boots and shoes;
and it consists in certain novel features, hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the base or standard of the machine, on which an upright B is disposed. A shaft b, provided with fast and loose pulleys d d, is journaled in said upright. The opposite end of said shaft bears a pinion f. A vertical track or way 0 is formed on one side of the upright B, and a shaft 9 is journaled in the top of said upright and projects through said ways. On the shaft 9 a crank-gearD is mounted, said gear meshing with the driving-pinion f. A block E is fitted to slide in the ways 0, and a rod h, pivoted eccentrically on the gear d, connects it with said block, said gear driving the block in its ways C in the ordinary manner of crank mechanisms. At the rear of the way C and parallel therewith there is a vertically-arranged groove 72', formed in the upright B. The crimping-blade H is secured by screws 5 to the lower end of the sliding block E and projects outwardly at the front of the machine. A vertically-adj ustable arm j projects. rearwardly from the blade H, and is provided at itsouter end with a roll or wheel m, which works in the vertical groove 71. of the upright B. Said arm is adjustable on the blade by means of screws k, which pass through the slot in said arm into said blade. The table I is mounted horizontally on the top of the body J, and on a staudardp at one end of said table a horizontally-swinging lever q is pivoted. Said lever is provided at its outer end with a vertically-arranged block 1", which registers with the upright groove h, and which is normally disposed in the path of the wheel m. On the forward end of the standard p a hub t is formed, through which the rod 0 is fitted to slide longitudinally. Said hub is chambered at 20 (see Fig. 2) around said rod. The other end of the rodis secured thereto at y, and a nut .2 is turned thereon, said nut being of a size suitable to slide in said chamber. Between the nut and bottom of said chamber a push-spring 15 is disposed around said rod. To the inner end of the rod 1; a crimping-jawP is secured. end of the lever (1 plays loosely on the rod 12, as best shown in Fig. 3, and between said lever and the jaw P a push-spring 16 is interposed. Registering with the jaw P there is a coinpanion crimping-jaw P, which is mounted in in the same manneuin the hub 25, its sliding rod '1) being spring pushed and provided with a out 2. The jaws P P have their upper edges formed on a curve at- 17, conforming to the shape of the curve 18 of the crimping-blade H. On the inner or working faces of the jaws P P there is formed a series of corrugations 20, which follow the line of curve of the edge of said jaws. An angular rod 25 projects horizontally from the front of The forward the table I, and fitted to slide on said rod 5 r to prevent lateral movement thereof.
said stop its slot 26 will register with the opening between the jaws P P. The plate M is designed to feed the upper leather onto the jaws and avoid the danger of injury to the hands of the operator from the crimpingblade.
In use the leather to be crimped is disposed on the feed plate or carriage M, which is moved from right to left by the operator, as viewed in Fig. 3. Power being applied to the shaft 1), the sliding crank-actuated block E is set in motion, forcing the blade H through the cartriage-slot 26 and between the jaws P P. As the block E descends, the wheel m engages the block 0" on the lever q, throwing that end of the lever outward. The opposite end of said lever, encircling the rod '0, drives the spring 16 against the jaw P, jamming said jaw tightly against the blade-H. The tension of the companion jaw P may be regulated at will by the force of its spring 15. Guide-rods 30 on the hubs t t slide in the jaws and serve Corrugated inner faces of the jaws engaging the leather retard the downward motion thereof and cause it to be formed or crimped into a shape correspondingto the curve of the crimping-blade in a manner which will be understood by all conversant with such matters without a more explicit description.
Having thus explained my invention, what I claim is- 1. In a crimping machine, a body, two spring-tensioned crimping-jaws mounted on rods in alignment on said body, a springpushed horizontal lever playing loosely on one of said rods, a verticallymoving crimpingblade adapted to work between said jaws, and
a wheel on said blade in position to engage the free rear end of said lever and automatically increase the tension on the corresponding crimping-jaw, substantially as specified.
2. In a crimping-machine, the combination of a table, a vertically-arranged way, a crankactnated block mounted to slide therein, a vertically-arranged crimping-blade secured to said block, two spring-pushed rods mounted in alignment on said table and respectively bearin g crimping-jaws, a roll mounted on said blade, a horizontal lever pivoted on said table and having its forward end loose on one of the j aw-rods and its rear end normally disposed in the path of said roll, and a pushspring interposed between said jaw and the adjacent end of said lever, substantially as described.
3. In a crimping-machine, the body and table, in combination with a crank-actuated slide E, the crimping-blade H, and roller m, mounted thereon, the spring-tensioned crimpin g-j aws P P, fitted to slide on said table, and a spring-pushed lever q, pivoted on said table and adapted to actuate said jaw P, the free end of said lever being normally disposed in the path of said wheel m, substantially as described.
4. In acrimping-machine,the spring-pushed crimping-jaws P P, in combination with the' table, the rod 25, and the curve-slotted carriage fitted to slide on said rod and registering with said jaws, substantially as described.
