WOODWORKING-MACHINE.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed November 12, 1907. Serial No. 401,798.

To all whom it may concern:

Cook and State of Illinois, have invented a new and Improved .Yoodworking-Machine, of which thefollowing is a full, clear, and exact description.

This invention contemplates an improved wood working machine for turning irregular or non-circular forms, the machine being more especially designed for shaping the eye ortion of ax and other handles, although it 1s not limited to this particular operation as it may be used with advantage in the shaping of other articles, as will be apparent when the construction of the machine is fully understood.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the machine complete, with an ax handle in position preparatory to the sha )ing of the eye portion thereof; Fig. 2 is a plan of the machine; Fig. 3 is a right end elevation; Fig. 4 is a fragmentary cross-sectional view showing one position of the former; Fig. 5 is a similar sec tion showing the former in a different posi-.

tion; Fig. 6 is a side elevation of the gripping-center, showing the bearing therefor n central vertical section; and Fig. 7 is a fragmentary sectional view through the sleeve and attached parts for controlling the move- I ment of the machine carriage.

The machine embodies in its construction a suitable frame comprising sup orts 10, 10, carrying a table 1 1, the latter being provided with bearings 12 on its upy :-r face, in which is journaled a. spindle 13, naving a. driving pulley 14, keyed 0r ctheruise secured thereto intermediate the bearings, and also having at the outside of one of said bearings near the forward end of the machine, a cutter-head 15, carrying a series of ad ustable cutting blades '16.

At the front side of the machine frame is a carriage 17, arranged substantially the same height as the table 11, and secured to standards 18, which are rigid with a sleeve 19,

slidabl and revolubly mounted in bearings i forme in the legs or supports 10 of the machine frame, and in an in ermediate bearing 20 carried by a bar 21 disposed longitudiopposite ends to the supports 10. The bear- Be it known that I, CLARENCE L. I'IART- 1 WELL, a citizen of the United States, and a resident of Chicago Heights,in the county of mg 20 carries a bracket or arm 2 which is provided with an overhanging forked end in which is fulcrumed a lever 23, the said lever shifted back and forth, to reciprocate the carriage and to move said carriage to and from the cutter-head when the lever is swung in a,

sidewise direction.

The standards 18 at the front end of the maare provided with a longitudinally and horizontally-arranged bearing 25, and the rear standard 18 is likewise extended and provided with two alining bearings 26, and also an arm these bearings are carried the spindles or shafts of the grippin center 27 and the tail center 28, the lattcr being in the nature ofa. cup for receiving the outer end of an ax hanaltcrnately against rests 30 and 31 which are secured to the machine table, the rest 30 being employed when shaping the ointed' edge and flat sides of the handle, as i lustrated ll].

ing the enlarged or rounded handle, as shown in Fig. 4.

For revolving the work and the former 29 during the shaping process, the work-holding port-ion of the the machine frame around one of the standards 18,.as best shown 1n Figs. 1 and 2. For

, moving the shaft of the tail center in gripping and releasing the work, the standard 18 vided with an arm or bracket 35, to which is I fulcrumed a foot-lever 36 of bell-crank form, the said lever being also pivotally connected 1 to a rod 37 passing througlrthe sleeve 19.

@The opposite end of this red is connected 110 i with a ever 37 fulcrumed intermediate its nally of the machine frame and secured at 1 length on an arm 38 rigid with the rear UNITED STATES, PATENT O FICE;

chine are extended above the carriage and 27 rigidly connected therewith. Within dle or other piece of work to be shaoed. The

tion of an ax handle, and is adapted to car Fig. 5, and the rest 31 being used when shap or gripping-center shaft is provided with a.

tudinal movement by a keeper 34, secured to i at the forward end of the machine is prostandard 18-. The upper end of the lever lent 37 a is swivelly connected with a collar 39 ad justably secured to the shaft of the tail center b the set-screw shown, or other equivaevice.

The tail center is normally forced to a retra cted position by a spring 40 secured to a fixed part of the machine and to the foot-lever 36. It is seen from this cons ruction that on depressing the foot-lever from its normal posit-ion, as shown in dotted outline in 'Fig. 1, to the position shown in full lines in said fi ure, the tail center will be advanced toward the work-holding center and will press the work into engagement with the latter, whereby it is enforced to revolve by the revolution of the crank 32.

hile I have shown and described the preferred manner of construction and arrangement of my improved machine, it will be a arent to those skilled in the art to which t 1e invention a pertains that various changes may be mat e, and I consider myself entitled to such modifications as fall within the scope of the annexed claims.

Having thus described my invention, I claim as new and desire to secure by Letters j Patent:

I ing one of the centers passing through the sleeve, and means for sliding and oscillating said sleeve.

2. The combination of a frame carrying a revoluble cutter, a sleeve journaled 1n the frame having work-holding means at opposite ends for supporting the work ad'acent to the cutter, means passing through the sleeve for varying the distance between the workholding means, and means for sliding and oscillating said sleeve.

3. The combination of a frame carrying a revoluble cutter, a sleeve journaled in the frame, having work-holding means for suporting the work adjacent to the cutter, a liand-lever for oscillating and sliding said sleeve, and means including a rod passing through said sleeve, for advancing and retracting one of said centers.

4. The combination of a frame provided with a rotary cutter, a sleeve slidably and oscillatively mounted in the frame, having standards rigid therewith, centers carried by saii standards, means for revolving one. of said centers, and means for advancing and retracting the other of said centers, including a rod passing through said sleeve.

5. The combination of a frame provided with a revoluble cutter. a carriage slidably and swingingly mounted at one side of said cutter, having centers for supporting the work, a hand-lever for swinging and sliding the carriage, and a foot-lever for advancing and retracting one of said centers.

6. The combination of a frame provided with cutting means, a sleeve journaled' in the frame, having standards rigid therewith, centers carried by said standards for supporting the work adjacent to said cutting means, a foot-lever fulcrumed to one of said standards, a rod connected with the foot-lever and passing through said sleeve, and a lever fulcrumed to the other of said standards and connected with said rod and to one of said centers.

7. The combination of a frame provided.

with a cutter, a carriage slidingl and swingingly mounted at one side of sait frame, having centers for supporting the work adjacent to said cutter, a hand lever for sliding and swinging the carriage, and a foot lever operable to advance and retract one of said centers.

S. The combination of a frame provided with a cutter, a device revolubly and slidingly mounted in the frame, having standards rigid therewith, centers carried by said standards, and a inanually operated lever connected at its end to said device and fulcrumed to a fixed part of the machine for E.
