WILLIAM H. SANDERS AND HENRY H. TALLEY, OF PETERSBURG, TENN.
SAW-MILL DOG.
SPECIFICATION forming part of Letters Patent No. 261,387, dated July 18, 1882.
Application filed May 1, 1882. (No model.)
To all whom it may concern:
Be it known that we, WILLIAM H. SAN- DEBS and H. H. TALLEY, of Petersburg, in the county of Lincoln and State of Tennessee, have invented a new and useful Improvement in Saw-Mill Dogs; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this specification, in Which- Figure l is aperspectivcview of a saw-mill carriage with our improved dog applied thereto. Fig. 2 is a cross-section in the line mm, Fig. 1; and Fig. 3 is a detail view.
Our invention relates to improvements in saw-mill dogs; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth.
In the accompanying drawings, a represents a head-block of a saw-mill, transversely adjustable on the carriage which carries the log to be sawed. To one end of the head-block, and flush with its end, is secured the knee 1), provided with the step or ofl'set 0, having the threaded hole (1, adapted to receive the reduced threaded end 0 of a standard, h, carrying at its upper end the block 2', provided with a longitudinal slot, j, thus forming jaws k, in which are journaled the segmental head at of the curved dog a and the segmental head 0 of the leverp. One of the jaws k is provided with a vertical slot, 1, in which is journaled the segmental head (1 of a second lever, r, at right angles to the other levers, the segmen' tal head q being provided with beveled gears on each of its faces, adapted to engage with the beveled gear on the segmental heads at 0, which also engage with each other. The segmental heads of the levers p and q, or of the former if the latter is not used, are made smaller than that of the segmental head We of the dog a, whereby greater power is obtained to force the dog into the log in contact with the end of the knee, and a better bite of the dog on the log is obtained.
1" represents an arm hinged to the end of the lever 7, so as to form a folding lever and increase the power when desired. When not in use the arm can be. folded over the lever 11, so as to be out of the way.
volve on the rod 1;.
8 represents a pawl pivoted to the outer face of one of the jaws k, and adapted to engage with a ratchet-wheel, t, on the end of thejournal of the segmental head m to hold the dog in place. By'this construction, after the headblock has been adjusted so that its end and the knee are in contact with the log on the saw-mill carriage, the dog can be raised or lowered to suit the diameter of the log by adjusting the screw e on the standard h up or down in the threaded hole 01, and the dog can be turned out of the way of the logby the same meanswhen placing the log against the knee, and the blockmay be also partially revolved, so as to change the position, if desirable, of the dog and the levers, so that the latter will be in a more convenient position to be operated. Power is then applied to either lever and the dog is forced into the log. The log may then be sawed into boards of any desired thickness; or, after having been squared by removing t-he slabs and reducing its dimensions, if necessary, the log may be dogged by thefollowing devices:
u represents a recess in the rear outer cornet of the knee 1), and t represents a vertical rod passing from top to bottom of the outer ends of the recess u, and through a vertical hole, 20, in a standard, it, provided with parallel semicircular gear b, extending half-way around the standard a, and adjusted to engage with a segmental geared head, 0, on the end of a lever, d, pivoted to the knee.
To the upper end of the standard a is secured or made integral with the standard the vertical dog 6, projecting beyond the headblock andknee, and adapted to partially re By this construction the dog can be turned aside to adjust the log in place against the knee, and the gear b still remain in engagement with head 0', and the dog e can be raised or lowered as desired.
Having thus described our invention, what we claim, and desire to secure by Letters Pat-- ent,"is-
V 1. The combination, with the head-block a and knee 1), provided with the threaded hole d, of the standard h, threaded at its lower end and carrying at its upper end the jaws 7c, and curved dog a, pivoted between said jaws,
whereby the dog can be raised and lowered to I provided with bevel-gear, and lever 1", at right accommodate logs of difl'erent diameters, substantially as described.
2. The combination, with the head-block a, knee b, provided with the threaded hole d, and standard h, threaded at its lower end and carrying at its upper end the jaws 7c, of the dog 11, provided with the pivoted segmental head m, having beveled gear, and lever 12, having pivoted segmental head 0, with beveled gear, the diameter of the segmental head 0 being less than that of the segmental head m, substantially as described.
3. The combination, with the revolving jaws 7c, of the dog 01, provided with the pivoted segmental head 12:, having beveled gear, folding lever 12 1*, having pivoted segmental head 0,
angles to the other levers, and provided with beveled gear on each of its faces, adapted to 20 engage with the heads m o, the heads 0 and q being of less diameter than the head We of the dog, substantially as described.
4. The combination, with the knee I), provided with the recess a, and rod 11, of the stand- 25 ard a, sliding on said rod, and provided with the semicircular gearb and dog e, and lever d, provided with a pivoted segmental geared head, 0, substantially as described.
