SAW SET AND GAGE.

SPECIFICATION forming pat 0f Letters Patent N0. 505,925, dated October 3, 1893.

v Application iiled May 24,1893. Serial No. 475.327. (No model.)

To a/ZZ whom it may concern:

Be it known that I, ENoCH E. RITCHIE, a cltizen of the United States, residing at Howard Lake, in the couhtyof Wright and State of Minnesota, have invented a new and useful Saw Setand Gage, of which the following 1s a specification.

My invention relates to an 'improved sawset and gage, the object in view being to pro- Vide a simple portable tool which combines the functions of a gage and a setting device, and which is adapted for-effectingwhat is known as a spring-set, in which the teeth are glven the necessary deflection without the use of a hammer and anvil, or equivalent dev1ce.

A further object of my invention is to pro-- vide means by which the set is gaged simultaneously with the operation of setting, thus facilitating the operation.

A further object of myinvention is to provide an improved gage for use in cutting drag-teeth or clearers which are employed'in cross-cut saws.

Furtherobjects and advantagesof myinvent1on will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings-Figure 1 is a side view of a gage embodying my invention applied in the operative position to'a saw-tooth in position for setting the same. Fig. 2 is a sectional view of the device applied in position to gage the set of a tooth. Fig. 3 is a perspective view of the tool. Fig. 4 is a rear view of the same.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates the body portion or handle of the device which is provided with an off-set head 2 which is approximately parallel with the body portion or handle, and is provided adjacent to its extremity with a transverse tooth receiving slot 3, the sides of which are slightly beveled, as shown clearly in Fig. 2, to enable the slot to be tted over the saw tooth while in an inclined position.

4-4 represent lateral ears which are turned down at their extremities to form bearing points 5 which are adapted to bear upon the surface of the saw blade, adjacent to the tooth, during the operation of setting the latten 7 is a gage screw which is threaded in thel head near its inner end and projects beyond the rear surface of the same to regulate the interval between the rear end of the head tedplate 10 which fits in said notch with its slot in positionto receive-the tooth to be cut. This plate is provided with a slotted ear, 11, which is engaged by a stationary set screw l2 whereby the distance of the surface of the gage plate below the plane of the ears or anges 8 may be adjusted, as desired, to enable the drag-teeth to be cut the preferred length.

The operation of this portion of the device is similar to that employed in various other tools of this class and hence needs no detail description; the only point of improvement residing in the adjustability of the gage plate whereby the amount to be cut from the tooth may be regulated by the position of the plate.

It will be seen that the relative arrangement of the tooth-receiving slot 3, the lateral bearing points and the gage screw, is such as to enable a tooth to be bent or set and immediately gaged without changing the position of the hand upon the tool, and essentially by a continuous movement o f said tool. For instance, the slot is engaged with a tooth and the free rear end of the handle is depressed to a point which is considered sufficient to produce the desired deflection of the tooth, the head of the device is raised slightly to disengage the slot from the tooth and the handle is carried down until the bearing points and gage screw bear upon the surface of the saw blade. In this position it can be readily seen at a glance if the tooth, which has-been operated upon, is deflected suiirocl ciently from the plane of the bladeor not. If not, the operation may be repeated, and if the deflection is too great the tooth may be bent back to bring it to its proper place. Thus the setting and gaging of the teeth may be accomplished alternately in rapid succession without necessitating any change of position of the tool in the hand of the operator.I

Having described my invention, what I claim isl. A saw set and gage having a fiat handle or body portion, an o-set head arranged in a plane approximately parallel with the bodyr portion or handle and provided at; its front end with a transversely disposed tooth-re-l ceiving slot a gage screw threaded in a perforation at the rear end o'f the head and pro` jecting beyond the rear surface thereof, and lateral integral ears arranged midway betweensaid slot and gage screw and having downturned `bearing-points substantially as specified.

2. As an improved article ofimanufacture,

a saw schandgage comprising a flat handle orbodyportion, provided with `integralflanges 8 and an intermediate notch 9, an adjustable downturned bearingpoints arranged at the terminals of a'transverse line interposed between the slot and the gage-screw substantially as specified.

3. As an improved article of manufacture, a saw set and gage comprising a handle or body-portion provided with a flat head having a transverse sl't 3, a gage screw 7, and opposite lateral bearing-points 5, arranged upon a transverse line lying between the said slot and gage-screw, y substantially as specified.

In testimony 'that Iclaim the foregong'as p my own I haveheretoaxed 'my'signature in the presence `of two witnesses.
