@stent @hijita THOMAS E. CHANDLER, 0F INDIANAPOLIS,v INDIANA.v
'Letters Patent No. 97,357, lated November 30, 1869.
IMPROVEMENT IN SAW-MILLS.
The Schedule referred to in these Lettere Patent and making part of the same.
To all whom 'it mcy concern.:
scription thereof', reference vbeing had to the accompanying drawing, and to the letters ot' reference marked thereon, making part oi' this specification.
My invention relates to mode of moving and ad justing the log to the saw'iu saw-mills, andr consists in arranging the devices, by which the knees are actuated to move the log, in such manner that the log may be mo'ed up to the saw in a parallel line with it, as innsawing boards, or that either end of the log may be set forward, as in sawing fence-posts or `other tapering timbers; the levers by which' the device is actuated being situated at the head end of the carriage, so Vas to be under the control of one attendant, who is not required to change his position to set the log.
' Figure l isa vertical longitudinal section of the I head-block, taken just inside of one of the side plates of the bed or frame.
Figure 2 is a side elevation of the head-block, the middle portion being cut out, in order lto shorten the ligure.
Figure 3 is aside view of the log-carriage, showing end views of the head-blocks and the arrangement of my device for moving and adjusting the log.
Similar letters of reference indicate corresponding lparts in'the several gures.
The Afollowing description will enable skilled artisans to make and use my invention.
K is the log-carriage, on which the head-blocks are placed. v i
The head-blocks are composed of the bed or frame A and the knees B, the latter being grooved in ythe sides, to receive and slide on the tongues or flanges,
formed in the topplate of' the bed A, as shown in.
grLhe log X rests on the beds A, and is moved up and held to the saw by means ofthe knees B.
The knees are'furnished with a cog-bar, C, lig. l, on the under side, which engages with a pinion, I), on a short shaft, J, having` its bearings in the two sides ofthefbed or frame A.
One end of shaft J projects through the side of the frame, far enough to receive the ratchet-wheel G, which is fixed on the projecting end of the shaft, as shown in fig.. 2.
The knees B are actuated to move the log up to the saw by means of pawls H H', hung in short levers O, fixed on the hollow rod I', and on the long rod I, that engage with the ratchet-wheel G, motion being imparted to the pawls by means of thelevers l? and S, which are fixed, by their lower ends, to the hollow rod I and rod I, respectively, by which the attendant gives a reciprocating rotary motion to these rod The long rod vI extends through both head-blocks, as shown in iig. 3, one end of which rests in the upright L, near the lixed head-block, the other end passing through the movable head-block, so that the latter may be moved back and forth, as may be required, for logs ofvarious lengths.
The rod I is grooved or key-seated, so that the lever O, iu which the pawls are'hung, may be moved to correspond with Vthe headblock.
The short levers are slotted, near the ends, in which the pawlsH H' are hung, so that the latter may be moved to or from the rods, in order to adjust the reach of the pawls to actnate the ratchets Gr alike.
A ratchet-bar, E, is attached to the inside of'ione of the side plates of the bed A, the notches in which are the same distance from-the saw-end of botlrfheadblocks, and a hooked lever, F, is hung in the knee B,
so as to engage vwith the notches in the ratchet-bar E,vfor the purpose of setting theknees at the same startingpoint, without requiring adjustment by the figured scale, usually made on the upper surface of the bed A.
It will be readily understood, that by moving both of the levers, P and S, simultaneously, both ends of the log will be moved up to the saw, in a parallel line with it, as in sawing-boards; and that by operating either of the levers I. S separately, either end of the log may be moved forward, as may berequired, as in sawing fence-posts or other tapering timber.
I am aware of the patent granted to Charles `Roberts, January 21,A1868, for improvement in saw-mills, and make-no clairntto the devices therein set forth.
Having thus fully described my invention,
What I claim as new, and desire to secure by Letters Patent, is-
The arrangement, herein described, of levers P S, shaft I, `and hollow shaft I', in connection with levers O, pawls H H', ratchet G, and pinion D, for actuating the knees B, as set forth.
