MACHINE FOR SAWING FELLIES SPECIFICATION forming part of Letters Patent No. 617,005, dated January 3, 1899.

Application filed June 29, 189 8. Serial No. 684,730. (No model.)

To (tZZ whom it may concern:

Be it known that I, ALEXANDER C. Wool), a citizen of the United States, residing at Advance, in the county of Davie and State of North Carolina, have invented a new and useful Machine for Sawing Fellies, of which the following is a specification.

My invention relates to sawing-machines, and particularly to an apparatus for sawing follies; and the object in View is to provide a simple, compact, and efficient construction and arrangement of parts whereby the uniform sawing of fellies in sections may be accomplished with facility and accuracy.

Further objects and advantages of this invention will appear in the following descrip tion, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a felly-sawing machine constructed in accordance with my invention. Fig. 2 is central vertical section of the same, taken in the plane of the saw-arbor. Fig. 3 is a plan View of the holder or carriage.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

The supporting-frame 1 maybe of any suitable construction, that which is illustrated in the drawings consisting of corner-uprights 2, connected by transverse and longitudinal bars 3 and l and an intermediate cross-bar 5. Mounted in suitable bearings 6 upon one of the end bars and said intermediate cross bar is a saw-arbor 7, carrying a belt-wheel 8 or equivalent means for communicating r0- tary motion to the arbor. Fixed to the sawarbor are the twin concavo convex sawblades 9. Supported by said framework is an inclined table 10, suitably braced at its under side and disposed at an inclination to the horizontal plane of the saw-arbor to suit the desired angle between the edgeand side surfaces of the felly-sections to be cut and also to suit the dish of the wheels of which said folly-sections are to form parts. Mounted for oscillatory movement upon this table is a work holder or carriage 11, of which the pivot-bolt 12 is at a point in alinement with the saw-arbor and concentric with the concavo-convex saw-blades. The floor of the holder or carriage, which is arranged in a frame consisting of parallel side bars 13 and convergent end bars 14 (at the apex of which is arranged said pivot-bolt)is slotted,as shown at 15, concentric with the pivot-bolt 12, and one of the side walls 13 of the holder is kerfed, as at 16, in registration with the slots 15, to allow the saw-blades, which operate in said slots 15, to pass into and out of the same.

The parallel side walls 13 are spaced at an interval corresponding approximately with the length of the blocks from which the fellysections are to be sawed, and in one of the said walls, preferably opposite to that in which said kerfs 16 are formed, is mounted a clamp-screw 17, carryinga swiveled clampplate 18, to bear against the end of a block, such as 19, arranged in the holder and provided at its outer end with a crank or similar handle 20. When a block is to be sawed, the holder or carriage is swung upon its pivot to carry it beyond the saw-blades, whereby the latter are withdrawn from the slots 15, the block is arranged between the side walls of the holder, and the clamp-screw is tightened to secure the block in place. The holder is then swung upon its pivot in the opposite direction to cause the saw-blades to enter the kerf 16, and therefore the slots 15, and simul taneously sever a folly-section from the block.

From the above description it will be seen that the construction is simple and that the entire operation thereof is under the control of the attendant, the side walls 13 being preferably extended to form grips 13, by which the attendant may swing the holder in the desired direction to either remove the saws from the slots or feed the frame during the sawing operation.

A further advantage of the construction described resides in the fact that the sawarbor is arranged in a horizontal plane, and hence the pulley can be traversed by a belt extending from an ordinary driving-shaft, such as those arranged in shops of the class in which machines of this kind are ordinarily employed. It will be seen, furthermore, that by reason of the specific construction of the holder or the carriage, with its spaced walls 13, between which the block of material is arranged, no endwise displacement of the felly-section can occur during the sawing operation, and hence the accuracy of the work is insured.

Various changesin the form,proportion,and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. In a fellysawing machine, the combination with a supporting-frame, of a horizontally-disposed saw-arbor carrying concavoconvex saw-blades, a table arranged at an inclination to the saw-arbor, a holder or carriage pivotally mounted for oscillatory movem ent upon said table and provided in its floor with parallel slots for the reception of the saw-blades, said holder also having upstanding side walls, and the pivot of the holder being concentric with the saw-blade, and a clamping device arranged at one edge of the holder between the planes of the contiguous ends of the slots in the floor thereof for securing a block of material in the holder by forcing the opposite end thereof against the remote side wall, substantially as specified.

2. In a telly-sawing machine, the combination with a supporting-frame and a saw-arbor mounted thereon, of a table arranged at an inclination to the plane of the saw-arboiytwin concavo-convex saws carried by the sawarbor, and extending upwardly above the plane of the table, a work holder or carriage pivotally mounted upon the table and provided in its floor with parallel slots for the reception of said saws, said holder or carriage also havingspaced side walls, in one of which are formed kerfs in alinement, respectively, with said saw-slots, to allow the removal of the saws from the interior of the holder, and clamping devices for securing a block of material in the holder, one of said side walls being extended rearwardly to form a carriageoperating grip or handle, substantially as specified.

3. In a telly-sawing machine, the combina tion with a supporting-frame and a saw-arbor mounted thereon and carrying twin concavoconvex saw-blades, of a table arranged at an inclination to the plane of the saw-arbor, a work holder or carriage pivotally mounted upon the table concentric with said sawblade and provided in its floor with parallel saw-slots for the reception of the saws, said holder also having parallel side walls in one of which are formed kerfs respectively in registration with the saw-slots to allow the removal of the saws from the interior of the holder preparatory to the arrangement of a block of material in the latter, and a clamping device, consisting of a clamp-screw, threaded in the other wall of the holder between the planes of the adjacent ends of said saw-slots and carrying a swiveled clampplate for engagement with the extremity of a block introduced between the side walls of the holder and supported by the floor thereof, said clamp-screw being provided with an exterior operating-handle and being adapted to force the block against the kerfed wall of the holder, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

ALEXANDER C. XVOOD.
