SPECIFICATION forming part of Letters Patent No. 765,313, dated July 19, 1904.

Application. led July 20, 1903.

ming the faces of spoke-tenons; and the object of the invention is to produce a simple, inexpensive, and effective machine of this class by which the spoke-tenons can be expeditiously and accurately cut to fit the mortises of the wheel-hub in which they are to be placed. I attain this result by the construction hereinafter described, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the machine. Fig. 2 is a plan thereof with the lever 7 broken away. Figs. 3 and 4. are perspective views, respectively, oftheV cutter-knife and one of the gage devices shown in the other views.

Referring to the said drawings by reference-numerals, 2 represents a frame which is rigidly secured by suitable bolts, such as 3, to a table tand is provided with oppositely-disposed vertical slots 5, forming guideways for a cutter-knife 6. .The knife (see Figs. 1 and 3) is provided with a diagonal or slanting cutting edge 6, which terminates at its lower corner in a transversely-arranged cutting-lip 6. 7 is a lever fulcrumed at-7 to a bracketarm 2 of the frame and extends across the frame, as clearly shown in Fig. 1, and its eX- tremity is formed into a handle 7 C The arm 8, integral with the lever, projects in the opposite directionfrom the fulcrum and is connected to the table by an extensible spring 8'.

Intermediate the handle and fulcrum the lever is connected by a link 9 with the aforesaid knife, whereby the latter is forced down coincidently with the handle or raised by the resiliency of the spring when the handle is released.

The slot in the portion of the frame forming the fulcrum for the lever operating the Serial No. 166,236. (No model.)

'knife extends to or nearly to the table, while the opposite slot is shorter and terminates suiciently above the tabley as to permit the spoke or other material to be cut to pass directly under the shorter slot and knife. Thus it will be seen with this construction when the knife with the inclined cutting edge isv directly over the material to be operated upon, and in starting the knife one has practically a point for a cutting edge to pierce the material and directly over the material and a gradual increase of resistance until the point has passed through the spoke in the downward movement of the knife.

10 represents gage devices against which the spoke 11 (shown in position to have its tenon trimmed) is held by a clamp-lever 12. The gage devices each comprise a block 13, which is advanced or withdrawn from the work by an adjustment screw 14, passing through a screw-threaded aperture 14/ of a standard 15, integral with a base-plate 16, fixedly secured to the table 4 by suitable fastenings, such as bolts 16. The block 13 is prevented from rotating with the adjustmentscrew by means of a guide-rod 17, fixedly secured to the said block and extending through standards 15 and 15. A thumb-screw 17 inserted in a corresponding aperture of standard 15, is provided to bear against the said guide-bar for locking the same and the block to which it is attached to any set position.

For convenience of manipulation I prefer-l ably provide a crank-handle 18 to each of the said adjustment-screws. The clamp-lever 12 is pivotally connected through any of a series of holes 19/ positioned adjacent to one end by a pin or bolt 19 to a frame-support 20, secured to the table. The work is clamped by swinging the free end 21 of the lever 12 so as two edge thereon and press the same against the aforementioned gage-blocks.

22 is a stop for predeterminately placing the work longitudinally of the table, so that the cut to be made upon the tenon and the shoulder thereof will coincide with the position of the knife. The said stop preferably comprises a shank 22', extending through the web 2 of the frame and provided with a rectangular bend 22, whereby a larger area IOO is presented to thc spoke end. rI`he stop is secured to its set position by a clamp-screw 23, fitted into a screw-tlireaded aperture 23 of the frame.

The operation of the device is extremely simply and will readily be understood from the foregoing description, taken in connection With the drawings; but it may be pointed out that theV gag'es capable of being' independently set provide means for cutting tenons having parallel or tapering facesfor instance, by advancing or retracting either of the gages.

I do not wish to be understood as confining myself to the precise construction hereinbefore described-as, for instance, to the manner of operating' the knife-actiiating lever by hand for a foot-pedal or other means may readily be substituted therefor.

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

1. In a spoke-tenon trimmer, the combination of a horizontal table, of a vertical guideframe having oppositelydisposed slots, one of which is shorter than the other, a bracket-arin made integral with said fraine-section having the longer slot, a lever fulcruined on said bracket-arm, a knife attached to said lever and reciprocating in said slots, transverselyarranged gage devices, means to clamp the work against said gage devices and a longitudinally-adjustable stop-gage passing through the lower end of the framework composing the longer slot, substantially as set forth.

2. In a spoke-tenon trimmer, the combination of a horizontal table, of avertical guide? frame, havingI oppositely disposed slots, a bracket-arn'i made integral with said frame, a lever fulcrumed on said bracket-arm one end of which is connected to the table by a spring' and the other end having a handle, a knife connected to said lever and reciprocating in said slots, of gage devices consisting of standards, adjusting-screws passing through said standards having blocks at their ends and an adjustable pivoted clamping-lever coperating with said adjustable block, substantially as set forth.

8. In a spoke-tenon trimmer, the combination of a table of a guide-frame at right angles thereto having oppositelydisposed slots, a bracket-arm made integral with said frame, a lever fulcrumed on said bracket-arm one end of which is connected to the table by a spring and the other end having a handle, a knife provided with an inclined edge terminating in a rectangular lip connected to said lever and reciprocating in said vertical slots, of gage devices consisting of standards, adjusting devices passing through said standards,

an adjustable pivoted clamping-lever coperating with said adjusting devices, and an adjustable stop, substantially as set forth.

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

GEORGE HANSEN.
