Patented Sept. 8, 1953 LUNI TED STATES PATENT OFFICE 2,651,220 f MEANS FOR THE sETTmG iiFsAwTEETiI Nils Rosenlund, Brooklyn, N. Y. Application May 31, 1952, Serial No. 291,033 1 Claim. (01. 76-64) This invention relates to a saw set for either cross-cut saws, circular saws or rip saws, and it has, among other objects, for its purpose to provide desirable and much needed adjusting means, and also to enable the user to set two ad'- joining teeth simultaneously.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings, forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a side elevational view of a saw set adapted for settingthe teeth of a cross-cut saw.

Figure 2 is a view similar to Figure 1, for setting the teeth of a circular saw.

Figure 3 is a side elevation of the invention shown in Figures 1 and 2.

Figure 4 is a top view of Figure 5 is a section on ure 3.

Figure 6 is a side elevational view of a saw set capable of setting two teeth simultaneously.

Figure 7 is a side elevation of the invention, as shown in Figure 6.

Figure 8 is a rear view in Figure 7.

Figure 9 is a top view of the invention, as shown in Figure 7.

Figure 10 is a central vertical section of Fig-- ure '7, looking in the direction of the arrows.

Figure 11 is a similar view as Figure 10, but in reverse position, looking in the direction 01' the arrows.

Referring more particularly to the drawings, the numeral l5 indicates a rest, or guide upon which the saws 6 and I6 are placed.

The set consists of handles I! and I1, kept in yielding relative position by a spring l8.

One of the arms H has an enlarged head I 9 provided with a bearing member 20, which rests against the saw, and a lug 2| pivoted at 22, said lug supports a set screw 23, whereby to determine the amount of set required by the user in regard to the saw.

The left hand handle I1 is at the top formed with an anvil 24, which also rests against the side of the saw in order to exert pressure against the setting teeth 25.

The amount of set is determined by the screw 23 acting on the saw blade |6 to the eflect that, when the screw 23 is substantially pulled the saw set; while the line 5-5 in Figof the invention shown 2 out in the lug 2|, the set will be small, whereas when screw 23 is screwed inwardly in the lug 2| the set will be greater.

Thus the distance the screw projects inside the end of the lug 2| against the saw blade decides the amount of setting. At the same time the screw 23 pressed against or gripping the saw blade prevents this from slipping.

Referring now to the Figures 6 to 11, the numeral 26 indicates a carpenter saw, in connection with which the this instance the handles 2'! and 21', which are pivoted at 28; the left hand handle 21 extends upwardly beyond the .pivot 28 and carries a guide 29 pivoted at 30 and upon which the saw 26 rests, when being set; the left hand handle carries also an extension 3| having an adjusting screw 32. The opposite handle 21 carries a head 33 upon which is pivoted at 34 a dog 35 provided with an adjusting screw 36.

Upon compressing the handles 21 and 21' pressure is exerted upon the teeth 31 and 38, which oppose each other, in order to create the necessary force, or pressure, against two adjoining teeth of a saw, whereby to give the latter the proper set, depending upon the setting of the screws 32 and 36, which restrict any excessive setting.

Thus, in the setting of more than a single tooth, as illustrated in Figure 7, the amount of is determined by the screws 32 and 36 acting on the saw blade 26 to the effect that, when the screws 32 and 36 are substantially pulled out in the extension 3| and dog 35, the "set will be small, whereas when the screws 32 and 36 are screwed inwardly in said extension and dog the set will be greater.

Thus, the distance the screws 32 and 36 project inside the ends of the extension 3| and dog 35 against the saw blade decides the amount 01' setting.

At the same time the screws 32 and 36 pressed against or gripping the saw blade prevent this from slipping.

shown and described herein.

What I claim as new, and desire to secure by Letters Patent of the United States, is:

A saw set comprising a pair of handles, a pivot securing the latter together, a guide pivoted to one of said handles and adapted to support a saw, an extension at the upper end of said handle, and a, set-adjusting screw mounted in said extension, a head formed at the upper end of the other handle, a dog pivotally secured to said head, and. a set-adjusting screw mounted in said dog.
