To ail whom, t may concern.-
Be it known that I, HANS AXDREAs HANsEN, a citizen of Norway, residing at Christiania, haveinvented certain new and useful Improvements in Saw-Sets; 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 it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Referring to the accompanying drawings, Figure l is a perspective view of my improved u saw-set. Fig. 2 is a side elevation thereof, the
handles being broken away; and Figs. 3 and l are isometric views of the gage-plates.
This inventionlrelates to that class of tools adapted for setting the teeth of saws, and has for its obj ect to provide an apparatus of simple construction, easily handled, and efficient in operation.
To these ends the invention consists in the combination, in a plier saw setting tool, of pivoted jaws, whereof one is providedy with a hammer and the other with an anvil for setting the teeth, with gage-plates vertically adjustable on the jaws to adapt the tool for operation on saw-blades of different widths or length of teeth, substantially as hereinafter iully described, and as set forth in the claims.
My improved saw-setting tool consists of two jaws,A B,having curved handles c b, said jaws being pivoted together atjp,`to operate like an ordinary pair of pliers, the handles being, as shown, curved in the same direction to afford a firm hold on the tool and to more conveniently operate the same.
S is a spreader-spring secured to one of the handles, its free end bearing upon the other,as usual.
C is a set-screw operatin g in a screw-threaded opening in the handle b, and serves to limit the movement of the jaws A B toward each other.
The j aw A is provided with an anvil, L, that projects from its inner face near the base of said jaw, said anvil having its outer face beveled upwardly and downwardly, as shown, to an inclined bearing-surface, Z, that gives the set or angle to the saw-teeth.
Thejaw B is provided with a hammer, L', projecting from a boss, b', and is so arranged relatively to the anvil L as to move in the plane ofthe inclined face Z of said anvil L, the face of the hammer L' being correspondingly beveled, as shown at Z', so that when both are brought together their inclined bearing-surfaces Z and Z' will face each other.
It is obvious that if the tooth of a saw is brought between the hammer L' and the anvil L andthe jaws brought together such tooth will be bent in one direction, and if the saw is reversed the next tooth will be bent in areverse direction 5 or the operation of setting may be perfor1ned,as usual, by setting each alternate tooth in the same direction and then reversing the saw and setting the intermediate teeth in a reverse direction.
In order to bring the teeth of the saw into proper position relatively to the anvil and hammer L L', and to adapt the tool for use on saws having teeth of different length, I employ a gage-plate, D, of angular forni, Fig. 4, having a slot, 7, ot' such width as to fit over the jaws A B, the length of the plate being such as to forma rest for the saw-teeth when inserted between the hammer and anvil. The vertical arm d' of the gage-plate D has an elongated slot, (Z2, and is secured to j aw A by means of a set-screw, E. According to the length of the teeth ofthe saw operated upon, this gageplate is adjusted closer to or farther from the hammer L and anvil L', as will be readily understood.
To afford the saw a firm bearing, and also to maintain the same in a position at right angles to the hammer and anvil, I employ a screw gage-plate, F, which, like gage-plate D, is adjustable vertically on jaw B, projects inwardly therefrom, and bears upon one side of the saw, the edge f of the plate lying in the plane of the hammer L', as shown.
rlhe plate F is suitably slotted, as shown in Fig. 3, and is secured to jaws B when adjusted to its proper position byineans of a set-screw,
E, so that saw-blades of different Widths may be operated upon, as will be readily understood.
To adapt the tool for use on very narrow sawblades the gage-plate F is made reversible to bring the plate proper close over the hammer L, as it is obvious that by applying the plate to the jaw B, so that the slotted shank f of said plate will project upwardly instead .of downwardly, the said plate .F may be brought close to the hammer L.
Having now particularly described and ascertained the nature of the said invention, I declare that what I claim is- 1. In a plier saw-set, the combination,with two pivoted jaws, A B,provided, respectively,
with an anvil and hammer L L of the ave l plate F, reversible and adjustable vertically on jaw B, substantially as and for the purpose specified.
2. In a plier saw-set, the eombination,with the jaws A B, having handles a b, and anvil and hammer L L', respectively, of the adjusting-screw C, the gage-plate D and the gageplate F, adjustable on jaws AB, respectively, said plates being arranged for operation, substantially as described, for the purpose specified.
In testimony whereof I affix my signature in presence of two witnesses.
