` UNITED STATES PATENT OFFICE.

`BENJAMIN F. FIRMAN, OF JAMESTOWN, NEW YORK, ASSIGNOR OF ONE- HALF TO DANIEL A. MARSH, OF SAME PLAGE.

SPECIFICATION forming part of Letters Patent No. 267,990, dated November 21, 1882.

Application filed September 4, 1882. (No model.)

To all irltom it may concern:

Be it known that I, BENJAMIN F. FIRMAN, of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in SplintlPlaners and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had` to the accompanying drawings,which form a part of this specifica-tion.

The object of my invention is to make a simple and eiicient machine for planing splints for chairs, 85e.; and the improvement Will be fully understood by the following specifications and the accompanying drawings, in which- Figure 1 is a side elevation, and Fig. 2 isa front view.

In the drawings, A represents the main body of the frame, which I generally makeof Wood, on which rests the cast frame B, it being securely fastened to the main frame by bolts.

The sides of the cast frame are nearly alike, and are cast in shape to receive the ends of the steel bedplate H in a groove at their sides, as shown; and they have also grooves in which the movable head C isheld, the object of this head being to hold the planeiron F in position by the clamp E, and the whole head can be raised or lowered at will by the leversde. This head hasleyebolt-s secured toits under side, and is attached to lever L in such a manner that the head can be brought down to the bed by the weight C being hung on the end of the lever as shown.

a is a set-screw to regulate the cut.

D D are friction-rollers, and are made to revolve by the pulleys P P, the belt on one side being crossed, so as to have them turn in the right direction to draw the splints through.

These rollers are held down by levers and weights, in the usual way.

The practical operation is to raise the planer-head by stepping the foot on the lever and insert one end of the splint under the planerknife, and far enough back to be taken by the friction-rollers and drawn through the machine. The end is readily caught and returned, so as to plane theend `not cut before. As the splints are got out with the'grain of the Wood, the stationary head for holding the plane is much better than a revolving knife or head, and can be run at much greater speed and the -splints all got out of a uniform thickness without changing the machine, and each splint finished without laying it down.

Having described myinvention, what I claim as new, and desire to secure by Letters Patent, Is-

41. In splint-planing machines, an adjustable head for holding a stationary knife, provided with set-screw and screws for gagin g the depth of cut, havin gfoot-levers to raise the lheadforinserting the splints, in combination with levers and weights -for adjusting the pressure and friction-roll ers for dra wing the splints through made to operate substantially as shown, and for the purpose set forth.

2. In splint-planing machines, theknife-head C, adjusting-levers e d, and set-screw a, in cornbination with rollers DD, pulleysP P, weights O G and K, and levers J L, all combined and made to operate in the manner shown, and for the purpose set forth. Y

In testimony that I claim the foregoing as my own invention I have hereto affixed my signat-ure in presence of two witnesses.
