UNITED STATES PATENT OFFICE.

JAMES A. ADAMS, OF ATLANTA, `GEORGIA.

MACHINE FOR MAKING EXCELSIOR.

SPECIFICATION forming part of Letters Patent No. 359,657, dated March 22, 1887.

Application filed July 8, 1886. Serial No. 207,515. (No model) citizen of the United States of America, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Machines for Making Excelsior; 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 letters or gures of reference marked thereon, which form a part of this specication.

This invention is an improvement in machines for making the article known in commerce as excelsior5 and it consists in a combination of plain and notched knives and devices for holding the wood to be cnt, as will be hereinafter fully described.

In the accompanying drawings, Figure I is a perspective view of the machine. The machine being a double one, one part is shown with a block of wood in position and the other y part with the block removed. Fig. II is a side view, partly'in section, of the arm that carries the block to be cut. Fig. III is a cross-section through this arm and the clamping device on the line xy. Fig. IV is the face, Fig. V is a section, and Fig. VI is the back, of the cutting slide or plane. Fig. VII shows the back of the notched knife. Fig. VIII- shows the swivel-jointed connection of the pitman with the plane.

Similar letters refer to similar parts.

In the drawings is shown a machineframe that may be of any construction or material adapted to carry the parts hereinafter described. On this frame, as shown,are holsters, to which are attached the rear ends of the springs A. To the other ends of the springs A are att-ached the arms a and a', which are provided with dogs l and 2 to clamp and hold the wood to be cut by piercing the ends in the usual manner, the dog l being moved by the screw 3, which carries the dog with it by reason of passing through the lugs on it, and being provided with the collars 4. The dogsl have a bearing on their upper sides against the arms a and c', and are held in that position about equal length.

by the screw 3, which passes through the strap 5 on the end ofthe arms and has a second bearing in the other end of the mortise.

Clamped by the dogs on the arm a is shown a piece ofwood, w, which is being held in position for cutting and rests on the cuttingplane B. The cutting7plane B is shown with the wood removed from the machine. These cutting-planes are each provided with two knives, one knife, b, in each being plain or smooth on its edge. The other, b', is recessed, having alternate short edges and spaces of The knives b are set higher than those marked b, for the purpose of cutting into the Wood sufficiently deep to prevent the planeknife from cutting except on the portion which is left by the spaces on the knife b. These knives are held firmly on their seats by capscrews s. As the knives b cut only on such parts as come opposite the spaces on the knives b', the slots in both knives are made wider than would accommodate the screws for the purpose of allowing adjustment to bring, at any time, the unworn parts of the knives b into use. For the purpose of raising the knives while the screws s hold them with sufficient firmness, the plates l? abut at one end on the knives and at the other on the back of the plane, and through them pass adjusting-screws p. The planes run in ways consisting of the topedges of the box-shaped frame F and the top and edge guides f, and are reciprocated by the cranks (l and C on a shaft journaled to the rear end of the frame. The pitmen R and R have on their front ends, and forming a connection with the lugs on the planes, a swivel, S, for allowing the plane, after one of the guides has been taken off, to be turned over for the purpose of removing or adjusting the knives. f

The springs A keep any desired pressure on the arms aand a', which` pressure can be regulated by placing liners under the ends or middle of the springs as required.

The arms may be raised to remove or replace lthe wood to be cut, or for any other purpose,

by the levers L, which are pivoted on an upper cross-beam of the frame, and are connected at their rear ends by hails m, and when the arms are raised they are held up by placing the front ends under the hooks m.

It is obvious that it is not necessary to the successful operation of the machine to have a double set of holders and cutters; but it is preferable, as by setting thc cranks opposite there is less vibration from the reciprocating parts of the machine.

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

l. In an excelsior-nlachine, a reciprocating plane provided with the knives b and b', cutting in opposite directions, said plane connccted by a swivel to its operating-pitman and sliding in guides, one of which is removable to allow the plane to be turned upon its edge for the purpose of adjusting the knives, the parts being combined and arranged Sub stantially as specified.

2. In an excelsior -1nachinc, a clamp for holding the wood to be cut, consisting of the stationary dog 2, the movable dog l, provided with lugs through which passes the screw 3, which also passes through and has a thread 25 in the strap 5, and collars 4, and arrn a, connected with the machine-frame by the springs A, substantially as shown, and for the purpose specified.

3. In an eXcelsior-niachine, the crank C, 3o the crank-pitman, and plane B, connected by a swivel, S, to allow the plane to be turned upon its edge, in combination with the springarms carrying the dogs 1 2, for holding the blocks XV in contact with the plane, and the 3 5 lever L, arranged to raise said springarms,and block-holding devices to allow the removal or replacement of the blocks XV, all substantially as shown and described.

In testimony whereof I aflixlny signature in 4o presence of two witnesses.

JAMES A ADAMS.
