IMPROVEMENT IN SWAGES FOR ZINC WASH-BOARDS.

Specification forming part of Letters Patent No. 38,4 l0, dated May 5, 1863.

To all whom t may concern.-

Be it known that we, JOHN POOLE and THoMAs J. PnTTIN, of the town of Harmar, in the county of Washington and State of Ohio, have invented a new and Improved Swage for the lI/Ianufacturing of Zinc Vaslr Boards; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a perspective view of the machine complete, with the drop raised. Fig. 2 is a vertical section through the center of the machine, showing sides of the frame, and the die-swages, bed-plate, snail-wheel or cam,and the position of the legs. Fig. 8 is a side of the die-swage. Fig. 4 is a top view of the bedplate. Fig. 5 is a side view ofthe snail-wheel. Fig. 6 is an end View of the die-swage.

Our swaging-machine consists'of a strong metal frame, A, Fig. 1, four feet six inches in length and fourteen inches in width. The widths of the sides and back end are equal, (seven inches in width.) About seven inches from the front end is a cross-tie, (not seen in drawings) over which, from the front end fourteen inches back and even with the upper surface, is a solid plate, B, Fig. 1, forniing a part of the frame. To this plate is fastened by screw-bolts from the under side of a corrugated bed-plate, C, Figs. 1, 2, and 8, of the size and shape of our wash-board plates. To the main body of this frame are four legs, D D D, Figs. 1 and 2, firmly fastened.` At or near the lengthwise center of the main frame are propel1 boxes or bearings E, Fig. 21 upon which a revolving shaft, F, Fig. 1, is placed. Upon this shaft is a snail-wheel or cam, G, Figs. 1, 2, and 5, firmly fastened. On the outer end ofsaid shaft a cog-wheel, H, about thirty inches in diameter, is fastened, into which gears a pinion (not shown) five or six inches in diameter, fastened to a shaft, (not shown,) which also rests upon bearings on the side of the main frame, in like manner and parallel with the first-mentioned shaft. On the'extreme outer end of this last-mentioned shaft, and against the pinion, is a pulley, I, Fig. 1, of any desired size. At the back end ofthe said main frame are boxes or bearings K, Figs. 1 and 2, on which rests and moves the end of a weighted lever or drop, L, Figs.

1 and 2, which is also'of width, length, and shape to correspond with the said main frame, except the front end. Across this drop-frame, right over and parallel with the first-mentioned shaft, is a strong bar, M, Figs. 1 and 2,-against which the snail-wheel Gworks. The forward end of this lever or drop Lis of an arched form-that is, it is made open in the front, so that the operator can put in his hand to adjust the zinc plate upon the bed-plate O, and hold it while the drop falls. In each side of the said opening or arch of the drop are dies N, Figs. 1 and 2, fastened in grooves by teniper-screws. These dies are of the same length of the corrugated bed-plate C, having `corresponding corrugations half across the width of face, the balance beinglevel or smooth on a line with the extreme edge ofthe corrugations,so as to exactly correspond with the shape of the bed-plate C, that when the weighted lever or drop falls on the already corrugated zinc plate lying on the bed-plate C the ends of the corrugations of zinc are all swaged to a straight line with the extreme line of corrugations, each end at the same time. rThis being the important feature of our machine, We will further explain the mode of operating the same. The operator takes the corrugated plates of zinc, places one at a time upony the corrugated bed-plate C, and properly adjusts it by his hand upon the top of it, the plates being held sidewise by proper guides. rlheweighted lever or drop L is then let fall with its whole weight upon the aforesaid zinc plate, instantly transforming the ends from a corrugated to a straight edge in line with one extreme side of the plate, thus fitting it to enter a groove cut in the sides of the wash-board frame, and being formed into such a shape that water will not enter freely said grooves, nor will it remain there should it enter.

Inthe upper part of the before-mentioned drop Lis an opening or cell, O, Fig. 1, to admit of the placing in of any additional weight that may be required. At the extreme forward end of the drop L are little lugs or catchesl? l?, Figs. 1 and 2. Corresponding lugs, R R, Figs. 1 and 2, are on the under or main frame, to which are attached arms or standards W W, Fig. 1, by screw-bolts, so as to play freely to and from the said uppercatches. These arms extend above the extreme elevation of said drop L, and are connected at the top by a rod, S, Fig. 1, reaching across from one to the other, and firmly fastened by secrewnuts at each end. These arms are held up against the catches by a strong spiral spring, U, Fig. 1, fastened to said rod S, and extending back over the drop to a similar rod, T, fastened to two stationary arms or standards, V V, Fig.

l, in like manner to the first mentioned.

The operation of our swaging-machine is as follows: A belt being put upon pulley I, motion is given to the main shaft F. The snailwheel G is brought in contact with the bar M of the drop L, and as the'snail-wheel is moved around the drop is raised to its extreme height, when the catches l? on the drop L are caught by the arms XV, having catches or shoulders for that purpose. The Zincplateis then placed to its proper position. The snail-wheel moving slowly gives time for the operator to adjust `the zinc. The arms W W may be held back, continuing the operation regularly, but

should the operator desire to stop the working of the drop L he only has to release his hold onthe arms WIW, and they will hold the drop from falling, thus stopping the machine. The snail is made to move as fast as the operator can conveniently adjust the zinc, thus giving great speed to the operation.

After having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The bed-plate C, the weighted lever-drop L, in combination with the cam or snail-wheel G and spring-catches W W, in the manner and for the purpose set forth.

lThis specilication signed and witnessed this 12th day of December', A. D. 1862.
