UNTTED i STATES PATENT 'Tirion CRIMPING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,515, dated February 8, 1881.

Application led May 19, 1880. (Model.)

To all whom 'it may concern:

Be it known that I, SAMUEL A. GOULD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Crimping-Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to construct and make use of the same, reference being had to the accom panying drawings, and to letters and figures of reference marked thereon, forming a part of this specification.

This invention relates to improvements in mechanism to be employed in crimping and preparing sheets of zinc to be used as faciugs in the manufacture of wash-boards; and it consists of certain novel features in the gen,

eral construction, arrangement, and operation of the parts, as will be hereinafter more fully explained in detail, and set forth in the claims.

Figure lis an end elevation of my improved crimping-machine Fig. 2, a side elevation of the same; Fig. 3, a vertical longitudinal eentral section in the plane x x, Fig. l; Fig. 4, a vertical transverse central section in the plane y y, Fig. 3; and Fig. 5 shows the `crimping bed-plate or former detached.

Referring to the drawings, A represents the inclosing and supporting frame-Work. B is a large roller carrying the series of cam-like projections C, which are rigidly attached to the periphery of said roller, and are arranged spirally upon the circumference of the same, as shown in Fig. 2 of the drawings.

The series of tumblcrs 6 are of a rectangular shape, move in a vertical plane, are loosely arranged in their proper working position, and are held in place by means ot the side bars, 7, as shownin the drawings. The lower ends ofthese tumblers rest upon the series of cams G, and the periphery of that portion of the roller B not covered by the cams alternately as the same is rotated, and the tumblers are caused to rise in regular succession relative to each other by the contact ofthe series of cams, and drop back again onto the roller B, by the force of gravity,when the cams pass beyond the point of engagement. These series of cams do not extend clear around the roller B in a spiral course, but a cylindrical roller B the tumblers are on a level.

bed-plate or former 1l, (shown in Fig. 5 of the surface is left on the periphery ofthe roller that will permit the series of tumblers to rest at the same level at a certain point of revolution-that is, when the last tumbler is re- 5 leased from contact' with the last cam, the first tumbler and first cani are about to engage, so at this point of revolution of the The upper ends of these tumblers engage with the inner ends of the series of bent levers 8, as shown in Fig. 4"of the drawings. These bent levers are loosely arranged in position, the outer ends resting in the recesses 9 in the frame-work A, and the under side of the inner ends resting upon the upper ends of the tnmblers 6. Resting upon the upper sides of the bent levers 8 are the series of followers 10, the under sides of which are of the proper shape to conform to the upper bearing-surface ofthe bent levers 8, as shown in Fig. 4 ofthe drawings. The top parts of these followers come in contact with the under side of the sheet of zinc and force the same into the recessed drawings,) which produces a pattern or design in accordance with the configurations carved thereon, the upper or impression side of the series of followers being always of proper shape to correspond to the configurations in the bed-plate or formery By way of illustration, one design is shown in Fig. 5 of the drawings. As many different designs or patterns may be produced as desired by simply removing the bed-plate and followers and substituting therefor others of a dierent pattern. Thefollowers are simply dropped loosely into place; but the bed-plate or former is rigidly attached to the top of the machine by mea-ns of the cross-bars 12, which are provided with the notches 13, thereby adapting these parts to securely engage with the ends A of lthe frame-work, and are further secured thereto by means of bolts or screws.

The movable frame 14 is placed at one end of the machine and arranged as shown in Fig. 1 of the drawings, and is adapted to move in a vertical plane, and is for the purpose of turning down one edge of the zinc facing ready to be inserted in the wooden back of the Washboard. The upper cross-piece of the frame 14 is partially cut away to form the shoulder 15,

IOO

(shown in Fig.L 2 of the drawings,) which nips and turns down. one edge of the zinc facing.

yThe cam 16 (shown in Fig. 1 of the drawings) is attached rigidly to the roller B, near the end, and is placed upon the periphery of the roller at a point directly opposite the irst ofthe series of cams C, counting from the right-hand end oi' the roller. When the roller B is rotated this cam 16 is brought in contact with the lower horizontal part of the frame 14 and forces the same downward, thus bringing the shoulder 15 of the upper cross-piece of the frame 14 in contact with the edge of the zinc, for the purpose above described. Attached to the upper cross-piece of the frame 14 is the lower end of the spiral spring 17, the upper end ot' this spring being connected to the cleat 18, as shown in Fig. 1 of the drawings, and is for the purpose of returning the frame 14 to its normal position when the lower end of the frame is released from contact with the cam 16.

The series otl tumblers, bent levers, and followers are all independent of each other, andr are simply dropped looselyinto their Workin g position in the machine, and when broken, or any of these parts are unevenly worn, duplicate pieces can be easily and conveniently in- 'serted Without causing any unnecessary delay.

The roller B is provided with the shaft 19 and the bearings 20.

The operation of the machine is as follows: When the roller B is caused to rotate, the series oi` cams C are brought in contact with the series of' tumblersin regular order of succession, and theseries of bent levers and followers are actuated in the same regular order, thereby gradually forming the design on the zinc or other material being operated upon. If the pattern were stamped out at one blow, the material would be broken and torn apart; but by this order of arrangement the sheet of zinc gradually receives the impression of the followers, and is thereby drawn inward from the loose side and readily adapts itself to the change of form.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a crimping-machine, the combination, with a former, of the roller B, provided with the series of cams C, the tumblers 6, the side bars, 7, the bent levers 8, and the followers 10, substantially as herein shown and described.

2. In a crimping-machine, the combination, with the roller B and the cam 16, of the vertical moving frame 14, provided with the shoulder 15, the spring 17, and the cleat 18, arranged and operatin g in the manner and for the purpose set forth.

3. In a crimping-machine, the combination of the roller B, the series of cams C, the series of tumblers 6, the side bars, 7, the series of crooked levers 8, the series of followers 10, and the bed-plate or former 11, all constructed, arranged, and operating in the manner and for the purposes herein set forth.

SAMUEL A. GOULD.
