Specification of Letters Patent;

Application filed April 25, 1912.. Serial No. 693,064.

with which the hammer lacts directly upon the teeth of the saw, and to provide a simple, efficient and practical saw set of inexpensive construction, capable of: :being easily and quickly adjusted to suit the character of the teeth of a saw, andadapted to be conven: iently handled by the operator and to absorb the jar or shockfro-m the blows of a hammer and thereby relieve the hand of the operator- With these and other objects in view, the

invention consists in the construction and.

novel combination of parts hereinafter fully described, illustratedjin the accompanying drawing, and pointedout in the claims hereto appended; it beingunderstood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or zsacrificing any of the advantages ofthe invention.

In the drawing :-Figure 1 is a perspective view of a saw set, constructed in accordance with this invention, and shown applied to a saw blade, the latter being illustratedin dotted lines. Fig. 2 is a longitudinal. sectional viewof the same,the saw blade being shown in full lines and the grip of the saw set in elevation. Fig. 3 is a detail sectional View, illustratingthe manner of mounting the adjustable gage. Fig.4 is a detail perspective view of the relatively fixedgage. Fig. 5 is a detail View, illustrating the arrangement of the lugs for interlocking the gage supporting plateior member with the body.

Like numerals of reference designate corresponding parts in all; the figures of the drawing.

In the accompanyingidrawing in;which is illustrated the preferred embodiment of the,

invention, 1 designates the body of the saw set, constructed of suitable metal and provided at the back with a relatively large grip 2 approximately egg-shape, with the ma or axis of the ellipse in an upright position and presenting a rounded convexrear: face, adapted to fit the hand EtHdhfl/Vll'lgl rounded side edges and which may beeasily and securely grasped with the thumb: and fingers of one hand. The grip forms. an elongated knob, which fits the hand, andjit is adapted to absorbshocks and relieve the: hand of the effect of the blows ofa hammer.

The body 1 is relatively narrow in advance of the grip, and it extends forwardly therefrom and isprovided at thefront withian upper longitudinally projecting portion: or extension 3 and havinga lower depending arm 4L. The front face 5 of the upper forwardly projecting portion is inclined :upwardly and inwardly to form ananvil, as clearly illustrated in Fig. 2 of the drawing. The depending arm Lis provided in its lower portion with a threaded perforation f6 Patented A r. 22,1913.

for the reception of an adjusting screwml extendingthrough the threaded perforation 6 and havinga tapered outer endS, adapted jto fit against the blade 9 of a saw below the teeth thereof.

The adjusting screw is provided at itsinner or rear end with ahead,

tion of the adjusting screw and engaging the and it is secured in its adjustment by a lock nut 10, arranged onthe mner or rear porrear ed e of the de )endin arm ot the bod j e 1 Ihe ad usting screw 1s at apted to malntam the saw set with the face of the anvil in proper position with relation to the tooth to be set, and it regulates the amount of set and enablesa uniiormzset of the teeth of a saw to be obtained.

The forwardlyprojectingupper portion 3 i has a concavely curved lower edge or face 11, provided at opposite sides of a central perforation 12 with allined lugs 13, adapted to project into a longitudinal slot 14 of a gage supporting plate or member 15 to prevent the latter from turning on a bolt 16,

which passes through the slot 14 and 100,

erlt'oration 12 for securing the gage supporting plate or member to the body of the saw set. The gage supportingplate or member is curved transversely and prethrough the seuts an upper convex faceto the; concave=l0e face or edge of the upper projecting portion of the bodyiof the saw set, and it extends from opposite sides of the saw set and is capable of longitudinal adjustment to ar-" range a relatively fixed gage 17 in proper position with relation to the anvil to suit the teeth of a saw blade, and it is secured in its adjustment by the bolt 16. The bolt 16, which is arranged at a slight inclination, is provided at its lower end with a head and is equipped at its upper end with a nut'18.

.Therelatively fixed gagel? is located at one side of the saw set, and it is provided at the bottom with a shank or attaching portion 19, curved to fit the upper face of the" plate or member 15 and secured to the same by a rivet '20, or other suitable fasteningde-i vice. The fixed gage consists ofan inner, vertical portion, a horizontal top portion anda depending. outer-portion, which is provided with an'integral inwardly extending projection 21, adapted-to fit in the recess of the dragor vclearing teeth 22 toenable the saw set :to be, quickly'and accurately posi: 'tionedon the saw blade; By "this: construction the relatively fixed gage may be easily and cheaply constructed by being stamped or otherwise formed from a piece of sheet metal; r i

Thegage supporting plate or member is equipped at the opposite side of the'saw-set with an adjustable'gage 23, provided with a curved shank or attachingportion 24, fitting the '(upper, face of the plate ormember 15 and'adjustably secured to the same by a bolt 25,-piercing the shank or attaching portion 24 and operatingin the slot '14 and provided with'a nut'26, arranged at the upper face of t-hevsaid shank or attaching portion. The

gage 23, which is adapted to rest upon the teeth of the saw blade, is of the same con-,

' struction as the gage 17 with the exception that the outer dependingportion is provided with a. continuous flan e 27, adapted to fit against the side faces of the teeth of the. saw blade at the side opposite that at which the body of the sawyset is arranged. The ad- 7 ju'stment of the gage supporting plate or member 15 enables-the relatively fixed gage 17 1 to be properly positioned with'relation to the anvil, so that when the projection 21 is placed in the recess of the drag teeth, the

tooth to be set'will be arranged centrally of the anvil. The adjustment of the gage '23 along the gage supporting plate or member enables the former to be arranged inthe desiredposition with relation to the anvil.

"The saw set after beingvadjusted to fit the teeth of a saw blade and to secure the desired amount of set may be quickly and accurately applied to thesame, and one or more blows of a hammer will properly set the'teeth of a saw.

' What is claimed is;:
