SPOKE- FACER.

SPECIFICATION forming part of Letters Patent No. 423,961, dated March 25, 1890.

Application filed January 8, 1890.

To all whom it may concern:

Be it known that 1, CHARLES SEYMOUR, of Defiance, in the county of Defiance and State of Ohio, have invented certain new and useful Improvements in Spoke-Facers; 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.

My invention relates to an improvement in spoke-machines, the object being to provide mechanism for facing or jointing the edges of spokes and reducing the widths of tenons to the dimensions to fit the mortises of the wheel-hubs.

To this end my invention consists in certain novel parts and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved machine. Fig. 2 is a plan view, and Fig. 3 is a detail.

Arepresents the frame of the machine, upon which the various working parts are arranged. The sliding carriage 1 is carried on the bed or guideway 2 as it is reciprocated. The slidswinging frame 2, which is pivotally supported at its lower end on the rotary driveshaft 3. This swinging arm is connected at its upper end by links at 4 with the reciprocating carriage 1, and it is connected by a pitman 5 to the gear-wheel 6, which latter is driven by a pinion 7 on the rotary shaft 8. A belt on wheel 9 on this shaft passes over a small pulley 10 on shaft 3, and motion is communicated from the former to the latter through this belt.

A pair of cutter-heads 11 11 are revolubly supported in the outer ends of the swinging frames 12 12, pivoted to the sliding carriage 1, and these frames are held normally inward by the tensile action of the spiral springs 13 13. These cutter-heads are driven by a pair of endless belts let 14, which pass over belt wheels 15 15 on the spindles of the cutterheads, over sheaves 16 16, supported in the upper ends of'the swinging frame 2, and also over the pulleys 17 17 on the drive-shaft 3, from which motion is imparted to the belt.

Belt-tighteners 18 18 are located on the Serial No. 336,258. (No model.)

swinging frame 2, and the belts 14 14 not only pass over them, but their tension is regulated by them.

The mechanism thus far described has been for reciprocating the sliding carriage and imparting motion to the outer heads. A description of the mechanism for regulating the position of the cutter-heads will ensue. A pair of guide-bars 19 19, made, preferably, of steel or other metal, are adj ustably held on the frame of the machine by means of the slides 20 20, and-the positions of the latter are varied in' order to change the positions of the guide-bars by the screws 21 21, which have their shanks 22 22 swiveled in the boxes 23 23, and their threaded ends are passed through correspondingly-threadedholes in the lugs 24 24 on the slides, so that as the screws are turned the slides are forced inward or outward, as the case may be. In this manner the guide-bars are shifted to regulate the positions of the cutter-heads. An arm 25 extends outward from each cutter-head over the guide-bars19 19, and at this point the arms are furnished with depending triangular lugs 26 26, which bear on the guide-bars, in contact with which they are normally held by the springs 13 13. A set-screw27 27 is located back of each triangular lug, and by turning the set-screw the lugs are moved to the desired positions and to throw the cutter-heads out of contact with the spoke being operated upon. After cutting the latter the required length the switches 28 28 are pivoted to slides 20, and their free ends are held in contact with the guide-bars by the plate-springs 29 29, the free ends of which rest in contact with the switches. As the carriage moves forward the triangular lugs travel outward on the switches, and in this manner the cutter-heads are thrown to one side, and consequently out of contact with the spoke. The spoke is passed between the adjustable guards 3O 30 and placed upon the table 31, and one end is held down by the clamp 32, while the other is held by the operator.

Motion is imparted to the machine through a pulley 33 on the drive shaft 3.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described, and pointed out in the claims, and hence I do not wish to limit myself to the exact construction herein set forth; but,

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

1. The combination, with a frame, a reciprocating carriage, and rotary cutter-heads connected therewith, of guide-tracks for the cutter-heads and means for changing the positions of the guide-tracks, substantially as set forth.

2. The combination, with a frame, a bed or guideway, a reciprocating carriage, and means for reciprocating the latter, of a pair of swinging frames carrying rotary cutter-heads and guide-tracks and switches for throwing the cutter-heads out of contact with the spoke being operated upon, substantially as set forth.

3. The combination, with a frame, a guideway, and reciprocating carriage, of a pair of pivoted frames, cutter-heads revolubly supported in the outer ends of the frames, and mechanism for rotating the cutter-heads and changing their positions, substantially as set forth.

4. The combination, with a frame, a guideway, a reciprocating carriage, and means for reciprocating the carriage, of swinging frames, rotary cutter-heads therein, adjustable guidetracks for regulating the travel of the cutterheads, and switches for throwing the cutterheads out of contact with the material being operated upon, substantially as set forth.

5. The combination, with the frame and reciprocating carriage, of swinging frames and rotary cutter-heads, substantially as set forth.

6. The combination, with the frame and reciprocating carriage, of a pair of pivoted frames, rotary cutters, and adjustable guides for the cutter-heads, substantiallyas set forth.

7. The combination, with a frame, a reciprocatin g carriage, swinging frames, rotary cutters, and means for reciprocating the carriage and imparting motion to the cutter-heads, of adjustable guide-bars, pivoted switches, and adjustable devices connected with the cutterheads and adapted to travel on the guides and switches to guide the cutters in their reciprocating movements, substantially as set forth.

8. The combination, with a frame, a reciprocatin g carriage, swinging frames, and rotary cutters, of guide-bars, screws or equivalent devices for changing the positions of the bars, pivoted switches, arms extending from the cutter-heads over the guide-bars, and adjustable blocks havingbeveled bearing-faces, said blocks adapted to bear against the guidetracks and switches, substantially as set forth.

9. The combination, with a frame, a guideway, a reciprocating carriage, a swinging arm, and gearing for swinging this arm, of swinging frames, rotary cutter-heads, belts for imparting motion to the cutter-heads, adjustable guide-tracks, switches, and means for regulating the positions of the cutter-heads and for insuring their travel upon the guide-tracks and switches, substantially as set forth.

10. The combination, with a frame, a reciprocating carriage, a swinging arm for comm unicating motion to the carriage, and means for swinging the arm, of swinging frames, rotary cutter-heads, guide-tracks, adjustable guards, and clamps for holding the spoke while being operated upon, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES SEYMOUR.
