SAW SET.

Application filed May 8,

This invention relates to a sawset. The object of the invention is the construction of a simple and efiicient device for eiiiciently holding a' saw-blade and at the same time setting the teeth thereof.

l Vith the foregoing and other objects in view, my invention comprises certam novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in side elevation of a crosscut sawset constructed in accordance with the present invention, while Figure 2 is a top plan view of the same.

Figure 3 is a sectional view taken on line 33, Figure 1 and looking in the direction of the arrows.

Figure 4 is a sectional view taken d l, Figure 2.

Figure 5 is a perspective view of the guide device.

on line perspective view of the set- Referring to the drawings by numerals,

1 designates the primary handle upon the inner end of which is the integral head 2. In the head 2 is positioned the detachable anvil. 3. This anvil 3 is provided with bevelled edges l on all sides or edges, whereas in Figure 5, I have shown a modified anvil 3 which has a straight edge 8 for the purpose of expediting the removal of the set from 49 the saw when there is too much set in a saw. The anvil 3 is mounted upon the inner end of the anvil adjusting screw 6.

A guide device 7 is in the head 2, this guide device being provided with a threaded shank 8 upon the outer end of which shank is butterfly nut 9. The guide device 7 is provided with an overhanging flange 10 and with an integral depending bifurcated flange 11, in the bifurcation of which works the inner end of setting plunger .12. On shank 8 between head 2 and flange 10 is coil spring 8 When the nut 9 is loosened spring 8 helps to move guide device 7 inwardly, for engaging with the saw teeth.

The plunger 12 has a coil spring 13 mounted on the rod like inner end 14 and the outer 1926. Serial No. 107,622.

end of plunger 12 is provided with a head 15 that is positioned in the lower end of setting plunger tork-link 16; a pin 17 extends through fork-link 16 and head 15 of plunger 12, pivotally fastening the same together. A pin 18 pivotally mounts the straddling end of fork-link 16 upon handle 1.

A setting plunger lever 19 is provided with a downwardly curved inner end 20; this end 20 is pivotally mounted at 21 upon jack-link 22; jack-link 22' is .pivotally mounted at 23 upon lugs 24; lugs 24'are integral with handle 1. ,The lever 19 is provided with an integral curved rearwardlyY extending heel 25. This heel 25 is adapted to strike against setting plunger screw 26.

A connecting rod 27 is pivotally fastened at 28 to the upper end of fork-link 16, whereas its other end is pivotally connected at 29 tothe curved end 20 of the lever 19.

An integral depending yoke 30 is formed upon the handle 1, and pivotally mounted, at 31, upon yoke 30, is a vice plunger handle 32. This handle is provided on its inner end with a pair of upstandingand rearwardly extending cars 32. These ears 32 are adapt-* ed to strike against abutment pin 38 to limit the downward or outward swinging movement of handle 32. Between ears 32 is pivotally mount-ed the flatinner end 34 of the vice plunger 85. This vice plunger 35 is provided with a rodlike outer end 36 which extends through the inner side of head 2 and is adapted to press against the saw-blade 37 (Fig. 1) opposite to outer end 36 is the anvil 3, between which anvil 3 and end 36 is clamped the saw-blade during the setting operation.

A setting screw 38 is mounted upon hana die 1 to limit the inward pivotal movement of handle 32, as the clamping action takes place on the sawblade 37. It will be understood that abutment pin 33 will prevent the handle 32 from swinging outward too tar.

.Referring particularly to Figure 8:

In the structure of the anvil 3 (Fig. 1), the anvil in the head 2 has four equal sides, and is bevelled on each side, whereas in Figure 8, I make the (1) side or edge 5 straight I and the objectof this is to expedite the removal of the set from the saw-blade 37 when there is too much set in the saw.

In operation, I first adjust the setting plunger adjusting screw 26 to gauge wanted. 1 H Then I adjust adjusting guide device 7 by turning the butterfly nut 9. By tightening this nut 9, a long set can be obtained, and by loosening nut 9, a short set from point of tooth can be obtained; the latter is'better for hardwood cutting. By giving saw the long set it may be filed several times without resetting. Vice plunger handle 32 operates vice plunger whereby the blade 37 is gripped and kept from springing wh le setting plunger IZforces set. By adpist ng screw 38' until it clears vice plunger handle 32, the said handle will have a slightly freer movement inwardly to obtain a greater gripping action on the saw-blade.

"1o"reinove set from saws that have too much set, firstloosen shank 8 by turning nut 9, then adjust screw 88 to gauge wanted, then place the entire device over the teeth of the blade and grip handles 1 and 32 until vice plunger handle 32 rests against screw 38. To find gauge desired, use the common spiderfiavhich is a tool used by all saw filers. f i

lVhile I have described the preferred embodiments of my. invention and illustrated the same in the accompanying drawings, certain ininor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive inanufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fallwithin the scope of the appended claims. 7
