SAW-SET.
Specification of Letters Patent.
Application filed April 21, 1913.
Patented J an. 27, 1914.
Serial No. 762,575.
To all whom it may concern Be it known that we, JAMES I. SIMMONS and AUoUsT P. Tnnsr, citizens of the United States, residing at \Vilmer, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Saw-Sets, of which the following is a specilication.
My invention relates to saw sets, and more i particularly relates to that class of saw sets which are intended to be used upon cross cut saws.
The object of my invention is to provide a saw set that will be complete in itself and may be manually operated without requiiing the use of a hammer or any other too Another object of the invention is to provide a saw set that may be adjusted to fit saw blades of various thicknesses, and which furthermore may be adjusted to regulate the l extent to which the teeth are angularly bent l or set.
Still another object is to provide a saw set provided with means for preventing the jaws of the tool from passing down over the blade of a saw beyond the teeth thereof.
Finally the object of the invention is to provide a device of the character described that will be strong, durable, simple and eflicient and comparatively easy to construct, and also one that will not be likely to get out of working order.
With these and various other objects in view, my invention has relation to certain novel features of the construction and operation, an example of which is described in the following specification, and illustrated in the accompanying drawing, wherein:
Figure 1 is a top view of my saw set showing the same in its operative relation to a saw. Fig. 2 is a view of the same in side elevation. Fig. 3 is a longitudinal vertical sectional view taken upon the line L23 of Fig. 1. Fig. 4 is a transverse vertical sectional view taken upon the line y-y of Fig. 2.
Referring now more particularly to the drawings, wherein like reference characters designate similar parts in all the figures, the numeral 1 denotes the body of the tool, which body is provided at one end with a suitable handle 2. The body of the tool is provided with an elongated slot 3 having a pair of saw tooth clamping jaws 4 and 5 mounted in its end portion farthest removed from the handle.
The working portions of the two jaws project down some distance beneath the body 1, the opposing faces of the jaws being substantially rectangular in shape. The jaw 4c is held in a stationary or rigid relation with the body 1 by a rivet 6. The jaw 5 which is adjustable to or from the jaw 1 is provided at its upper extremity with a threaded shank 7 receiving a thumb nut 8 adapted to clamp upon a washer 9 resting upon the body 1. The nut 8 is screwed tight against the washer 9 when it is desired to hold the jaw 5 adjusted in a certain position. The tool is shown in the drawing with a portion of a saw blade 11 interposed between the jaws l and 5, the tool being in position to set one of the teeth of said blade. During the operation of setting any tooth of the saw, a considerable strain is exerted upon the movable jaw 5, tending to shift it from the jaw 1. Since the clamping effect of the thumb nut 8 might not be sufficient to prevent such displacement, we further j employ an adjusting screw 10 mounted parallel to the body of the tool at the end thereof, the threaded extremity of said screw being made to project into the slot 3, so that it may support the jaw 5 when the latter is adjusted in its proper place. The opposing faces of the jaws 4t and 5 are provided with corresponding recesses 12 receiving the extremities of a coiled spring 13. This spring tends to hold the two jaws constantly spaced as far as is permitted by the thumb screw 8 and the adjusting screw 10, so that it is not necessary to manually shift the jaws apart after the parts 8 and 10 have been loosened.
In order to limit the extent to which the jaws may be passed down over the toothed edge of a saw, a stop member let of rectangular cross section is rigidly mounted in the working face of the stationary jaw d and is made to project perpendicularly from said face into a recess 15 provided in the working face of the jaw 5. As the tool is brought into its working position, the member 14 will contact with the saw tooth which is to be set and will prevent the being slipped down any farther over said tooth than necessary to afford them a firm grip upon the tooth. The member 1-l fits slidably in the recess 15, so as not to interfere with any variation in the spaced relation of the two jaws. The member 14 will preferably be of brass since this ma terial is sufficiently soft to avoid marring or nicking the saw teeth by contact with same.
lVithin the slot 3 between the jaw 4; and the handle 2, a gage member 16 is adjust-ably mounted, said member having its lower por: tion projecting some distance beneath the body 1 and curved slightly in the direction of the jaw 4. The member 16 will prefer ably be gradually tapered from the upper to its lower end. The upper end of the member 16 is provided with a threaded shank 17 projecting above the member 1 and receiving a thumb nut 18 adapted to clamp upon a washer 19 resting upon the member 1. Thus it is apparent that the member 16 may be adjusted at various positions in the slot 3 by loosening the thumb nut 18.
In using the above described tool, the jaw 5 is first adjusted in a spaced relation to the jaw 4 such that the jaws may be slipped down at each side of a saw tooth without clamping upon the tooth. The thumb screw 8 is then tightened and the screw 10 will be adjusted until the threaded end bears upon the rear face of the jaw No further adj ustment of the movable jaw will be necessary until the teeth of the saw have all been set. After any saw tooth has been interposed between the jaws at and 5, the tooth is set by exerting a downward pressure upon thehandle 2, said handle together with the body of the tool forming a lever and the root port-ion of the tooth acting as a fulcrum. The amount of set imparted to any tooth is limited by contact of the lower end of the gage member 16 with the lateral face of the saw. Each of the members 4i, 5, and 16 will preferably be provided with shoulders 20 at each side bearing upon the under face of the body 1 to prevent upward displacement of said members relative to said body.
The invention is presented as including all such modifications and changes as properly come within the scope of the following claims:
hat we claim is:
1. A. saw set comprising an elongated body formed with a longitudinal slot in one end and having a handle at the other, a pair of jaws one of which is rigidly mounted in said slot and the other adjustable therein to or from the rigid aw, means for holding the adjustable jaw stationary in various spaced relations to the rigid jaw, means interposed between the jaws tending to increase their spaced relation, and a stop forming member interposed between the jaws limiting their downward movement over the toothed edge of a saw.
.2. A saw set comprising an elongated body formed with a longitudinalslot in one end and having a handle at. the other, a pair of jaws one of which is rigidly mounted in said slot and the other adjustable therein to or from the rigid jaw, means for holding the adjustable jaw stationary in various spaced relations to the rigid j aw, means interposed between the jaws tending to increase their spaced relation, and a stop forming mem ber having one extremity rigidly mounted in the stationary jaw and its other extremity recessed in the working face of the adjustable jaw.
