.HANGING RECIPROCATING SAW-GANG- No.l184
Patented Nov. 21
r JM 1 w UNITED STATES PATENT OFFICE.,
QLIVER C. MEIGS, OF DUBUQUE, IOWA.
IMPROVEMENT IN HANGING REClPROCATING SAW-GANGS.
Specication forming part of Letters Patent No. 184,474, dated November 21, 1876; application filed May 2, 1876.
To all whom it may concern Be it known that I, OLIVER C. MEIGs, of Dubuque, in the county of Dubuque and State of Iowa, have invented a new and useful Improvement in Hanging Reciprocating Saw- Gangs, which is fully described in the following specification, reference being had to the vand Fig. d, a viewin detail, showing the construction of the gage and hooks.
My invention relates to the method of hanging the saws in the gate; and its object is to secure an adjustable device, which may be made to fit the saws perfectly, and at the same time hold them firmly in position.
The invention consists in connecting the gage-block hooks and straps, by -means of which the saws are held to the gate, by a pivoted joint 5 also, in making said blocks wedgeshaped upon their upper faces; and also in the employment of three set-screws, in combination with the gage-blocks and hooks, for clamping the saws between the blocks and holding them in position.
In the drawings, A represents a saw-gate, of any ordinary construction, which is provided at its lower end with a hook-bar, B, having a dovetailed flange, b, with which the hooks C engage. The hooks G are constructed with a small circular lug, c, projecting from one side, Aas clearly shown in Fig. 4 of the drawings. The gage-blocks D are slightly recessed at one side, asseen at d in Fig. 4 of the drawings, and provided with holes which receive the projections c on the hooks C when used in fixing the saws in position. The gage-blocks D are also made with their upper faces Wedgeshaped or pointed, as shown in Figs. 2 and 4 ot' the drawings. The saws E are provided with thin v anges e at their ends, as shown in the drawings, upon which the lower edges of the gageblocks D rest, one block being placed on each side of the saw. Brackets a are attached to the side pieces of the saw-gate A, in each of whichare mounted three set-screws, F, which are arranged in triangular form, corresponding somewhat to the gage-blocks D. The two lower screws of the series are intended to be brought against the outside of the gage-block.
lower ends, and are pivoted to the key-straps y G, which are used instead ot' hooks at the lower end of the gate. These straps G extend up through the upper cross-bar of the gate A, and are provided with keys g, in the usual manner.
The gage-blocks D are intended to be made of such thickness as to space the saws properly for sawing inch lumber. It' it is desired to saw stui' of a greater thickness, wooden blocks H are placed between the gage-blocks, as shown in Figs. 1 and 3 of the drawings. These blocks, when used, should have their upper faces .wedge-shaped or pointed, to correspond with the form ofthe gage-blocks. v
The operation ot'- my invention is as follows: The gage-blocks D are placed one on each side of a saw, the edges of the block resting upon' theledges e on the saw-blades, and the hooks C are inserted in the gage-blocks, as described, i
and' loosely hooked over the iiange b. The gage-blocks being tted to the saws, and attached to the key-straps at the upper end of the gate in a similar manner, the ke'ys are driven slightly, so as to straighten the saws and bring everything into position: The setscrews F are then turned up firmly against the blocks and hooks or straps. As the gagev Having' thus described my invention, what I claim as new, and desire to secure by Letters Paten t, is
1. The combination of the gage-blocks D,
hooks C, and key-straps G, the gageblocks being pivoted to the hooks or straps, substantially as and for the purpose set forth.
2. The three setscrews F, arranged as described, incombiuation wlth the gageblocks D, hooks C, and key-straps Gr, substantially as and for the purposes set forth.
