SAW-MILL SET-WORKS.
SPECIFICATION forming part of Letters Patent No. 351,974, dated November 2, 1326.
' Appliltiltion med May 28, 1886. Serial No. 203,523. (No model To aZl whom, it may concern:
Be it known that I, FRANK J GLEASON, a citizen of the United States, residing at Van Wert, in the county of Van VVert and State of Ohio, have invented certain new and useful Improvements in Mechanism for Operating the Head-Blocks of Saw-Mill Carriages; 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 itappertains to make and use the same, reference-being had to the accompanying drawings and letters of reference marked thereon, which form a part of this specification.
Likeletters refer to similar parts throughout the several views.
Figure 1 of the drawings is an end view of a saw-mill carriage provided with my improved set-works. Fig. 2 is a plan view of the same. y
My invention relatesto saw-mills, and more especially to mechanism for operating the knees of saw-mill carriages, whereby the same may be automatically advanced or retracted by means of a reversibleshaft and connections, all under theimmediate control of the sawyer,
as more fully hereinafter described, shown in the drawings, and particularly pointed out in the claims.
Referring to the said drawings, which illustrate the preferable way of carrying out my invention, A represents the carriage, provided with rollers a, running upon ways a and reciprocated in any of the well-known ways; but as the mechanism for reciprocating the carriage forms no part of thisinvention I have not shown it in the drawings.
B B are the knees moving in ways b in the cross-bars B of the carriage. These knees are provided each with a screw-threaded rod, 0, one end of which engages an internallythreaded opening in theunder side of the knee, as is common in this class of devices. The opposite end of each of these rods is provided with a beveled pinion, c. Secured to the side of the carriage farthest remote from the saw are brackets D D. E is a rod or shaft having hearings in said brackets, and secured to said shaft are the beveled pinions e e, located at such points on said shaft as to engage the beveled pinions c c, as clearly shown in Fig. 2.
F is a bracket, secured to the same side of the carriage as the bracket D, and in this bracket is journaledthe stub-shaft G, carrying beneath the floorof the mill, and in these boxes is journaled the horizontal shaft K, carrying upon one end a friction wheel, K, and at the other end a beveled pinion, k. The bearing for the shaft K is elongated, as shown in dotted lines in Fig. 1, and its bearing in the box I is made tapering, as shown in dotted lines in the same figure, to provide for the raising and lowering of the outer end of said shalt without wrenching the same. L is a lever pivoted at any suitable point overhead, and L is a lever pivoted at Z beneath the floor of the mill.
M is a link sleeved upon the shaft K near its outer end and connected with the lever L at a point between its ends.
Z is a rod connecting the outer ends of the levers L and L, and m is a cord or rope attached to the opposite end of the lever L and extending down within convenient reach of the sawyer, and is preferably provided with a ring or handle, as shown in Fig. 1, although of course this handle is not necessary.
N is an inclined shaftjournaled in suitable bearings extending up through the floor, and upon its upper end carrying a worm-gear, n, meshing with the worm h on the saw-arbor. O is a sleeve on said shaft N and secured thereon by means of a feather and spline, so that said sleeve will rotate with the shaft, and yet allow of a longitudinal adjustment of said sleeve, for a purpose hereinafter described,and carrying at opposite ends beveled pinions 0 0, oppositely inclined, as shown in the drawings. Attached to this sleeve 0 is one end of the lever P, the opposite end of which projects up through the floor of the mill, where it is pivotally connected with the lever P, which is fulcrumed at p on the upright p, secured to the floor of the mill, as shown. The free end of this lever is arranged in proximity to the sawyer, and is preferably formed with a concave portion, Q, to receive the knee of the sawyer.
In operation the shaft N is continuously rotated by the engagement of its gear n with the worm on the saw-arbor. Vhen it is desired to advance the knees, the sleeve is moved longitudinally on its shaft by means of the le ver P and connections, so as to throw one of the beveled pinions on said sleeve into engagement with the pinion k on the shaft K. This gives a rotary motion to the said shaft K,when, by pulling upon the cord m, the outer end of said shaft K is raised suflieiently to throw its friction-wheel K into contact with the friction-wheel G on the shaft G. This, through the medium of the beveled pinions gg, im-
- parts a rotary motion to the shaft E, which,
through the medium of the beveled pinions 0 6 and the rods b, imparts a transverse motion to the knees B B simultaneously. \Vhen the head-blocks have been advanced the desired distance, the operator releases his hold upon the cord m,when the shaft K falls of its own weight, throwing the friction-wheel K out of engagement with the friction-wheel G. Vhen it is desired to move the knees in the opposite direction, the lever P is moved so as to throw the opposite pinion on the sleeve 0 into engagement with the pinion k on the shaft K. Said shaft is revolved in the opposite direction, when, by raising the outer end of the shaft K, the engagement of the friction-wheels G K imparts a motion to the shaft E, and consequently to theknees, in a direction contrary to that imparted thereto when the shaft K was revolved in the opposite direction.
The construction above described is what at present I consider the most preferable; but I do not wish to limit myself strictly thereto, as it is evident that changes may be made without departing from the spirit and scope of my invention. For instance,other meanssuch as a quarter-twist beltmay be used in place of the worm 71 and worm-gear n for rotating the shaft N, it being only necessary that said shaftbe given a continuous rotary motion from the saw-arbor.
Having thus described my invention and set forth its merits, what I claim to be new, and desire to secure by Letters Patent, is-
1. The combination,with the saw-arbor, the carriage carrying friction-wheel G, and ashaft parallel with the saw-arbor and deriving motion therefrom through intermediate connections, 2. friction-wheel on the outer end of said shaft,lever L,pivoted overhead,lever L, pivoted beneath the floor, link M, sleeved upon said shaft near its outer end, and connected with the lever L, the rod 1, and cord m, all substantially as described, and for the purpose set forth.
2. The combination, with the saw arbor provided with worm h, and the saw-carriage provided with knees, of the shaft N, arranged substantially at right angles to said saw-arbor, and provided with worm-gear n, the shaft K, parallel with the saw-arbor, means for revolving said shaft from the shaft N in either direction at the will of the operator, and connections, substantially as described, between the shaft K and knees, substantially as set forth.
3. The combination, with the saw arbor provided with worm h, the shaft N, arranged substantially at right angles thereto, and provided with worm-gear n, the shaft K, parallel with the saw arbor, and carrying frictionwheel K, of the sleeve 0 on said shaft N, levers P P, for operating said sleeve, frictionwheel G on the saw-carriage, and connections between said friction wheel and the headblocks, as set forth.
4. The combination, with a saw arbor, knees, the saw carriage carrying frictionwheel G, connections between said wheel and the knees, and the shaft K, parallel with the saw arbor, and deriving motion therefrom through intermediate connections, of the friction-wheel K on the outer end of said shaft, and the means, substantially as described, for raising said outer end of the shaft K, as and for the purposes specified.
5. The combination,with the saw-arbor, sawcarriage, and knees, of the shaft N, deriving motion from said saw-arbor, the shaft K, parallel with the saw-arbor, and carrying beveled pinion k, connections, substantially as described, between said shaft K and the knees, the sleeve 0 on the shaft N, and carrying reverselyinclined beveled pinions o 0, and the levers P P, for sliding said sleeve longitudinally on the shaft N, substantially as and for the purposes specified.
In testimony whereof I affix my signature in presence of two witnesses.
FRANK J. GLEASON.
