SPECIFICATION formingpart of Letters Patent No. 412,242, dated October 8, 1889.

Application filed June 16, 1888.

To aZZ whom it may concern:

Be it known that I, HELMIT N. DAWSON, a citizen of the United States, residing at Oak Hill, in the county of Clay and State of Kansas, have invented certain new and useful Improvements in Quadruple Tin Folders; 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, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in machines for folding tin and other material in sheet form. for roofing and other purposes; and the objects are to construct a folder that shall atone and the same movement turn all four of the edges at one and the same time in a perfect manner and ready for immediate use. I attain these objects by means of the mechanism hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 is a plan of my machine; Fig. 2, a front elevation, having a part of the frame, the crank, and foot-treadle removed. Fig. 3 is also a front elevation, with tin plate removed and upper platen raised.

Similarlettcrs refer to similar parts throughout the several views.

My machine consists of the frame A, table or bed B, lower platen O, with bevel-edge 0c and bendingdevers r r hinged to the sides thereof and actuated by the connecting-rods D D; upper platen G, having bevel-edges 7c is and bending-levers e e, hinged to the sides thereof and actuated by the connecting-rods E E, the several connecting-rods D D and E E being adjust-able by means of the slots f f and bolts if; the standard F, head H, with guide-piece p sliding in the housing I, which is supported by braces J J from the frame;

the standard-brace 0; plate K, having notched inclined slot n, lever L, bracket m, eccentrics c c, firmly secured to the shafts a and b, and having adjusting-holes y y and The shafts a and h are both in the same plane, and on them are mounted the bevel-gears g and 72. in contact with each other. The shaft co is U-shaped opposite Serial No. 277,800. (No model.)

the shaft 1). The crank d is secured to the shaft 19 and connected by the rod 6 with the foot-treadle raised by the spring .9.

l, 2, 3, and 4 are guide-pins passing through holes in the bending-levers, and 5 a sheet of tin or other material in position to be folded.

The lower platen O is immovably secured to the table or bed B. The upper platen G is attached to and raised and lowered by the standard F, which is secured to the lever L, the lever L being pivoted at one end to the bracket or and held in position by engaging the ratchet-teeth in the plate K. The platen G is raised or lowered by the lateral moving of the lever L, the incline to the slot at giving the vertical movement to the standard F. Vhen lowered, the standard F is steadied in its position by coming in contact with the braces 0 and J, substantially as shown.

When used as a double folder only, it may or may not be necessary to avoid the action of two of the bending-levers by detaching them from their respective rods. It will not be necessary if the sheet to be folded be no wider one way than the platen itself. For instance, if the machine be constructed to fold the four edges of a sheet twenty by twentyeight inches, two edges of a sheet eighteen by twenty-eight inches could be folded without detaching the bending-levers.

It will readilybe seen that the foot-treadle may be removed and the machine worked by hand by means of the crank d, if preferred.

Having thus describedmy invention, What I claim as new, and desire to secure by Letters Patent, is-- In a folder, the combination, with the stationary and movable platens having bendinglevers hinged to the sides thereof, of a standard secured to the upper platen, a lever connected with said standard, and a plate having an inclined toothed slot receiving one end of said lever, whereby the lateral movement of the lever in said plate imparts a vertical movement to the standard and movable platen, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
