RAKER- GA GE.

To all whom it warty concern. Be it known that I, Hnnemrr ELRoY Gonnox, a citizen of the United States, and a" resident of Seattle, in the county of King and State of lVashmgton, have lnvented an Improvement in Baker-Gages, of which the following is a specification. I

My present invention relates to combined saw tools and more particularly to devices for use in connection with the sharpening and swaging of saw teeth, and my object is V to provide a device of this character having ass a novel and highly efiective gage clip for use in connection with the sharpening op eration and a novel and highly useful gage for use in connection with the swaging operation, all of which parts are combined in a single device which may be readily manipulated and accurately adjusted and which permits of an unobstructed view at all times of the work being done.

In the accompanying drawing which illustrates my invention, Figure 1, is a side elevation of my improved eevice. Fig. 2, is a central vertical transverse section taken therethrough. Fig. 3, is another vertical transverse section, taken substantially on line 33 of Fig. 1. Fi 4, is a top plan view of the intermediate portion of the device, and, Fig. 5, is a side elevation of the lower central portion of the device looking from the opposite side as compared to Fig. 1, and illustrating the swaging means. 7

Referring now to these figures, A represents the frame body or block of my improved tool, which is provided with central cut out portions a and a at its upper and lower edges respectively and which is provided at'its upper and lower edges upon opposite sides of the cut out portions with laterally projecting lugs o to which lugs are secured longitudinal strips B and C, upon the upper and lower ed es of the body frame or block A respectively and upon opposite sides of the cut out portions or, and a.

It will be noted that the. strips B and C are secured in such manner that they may be readily removed either for repair or substitution, by means of a plurality of small screws or the like extending into the lugs a It is to be noted also that the strips B and C are laterally extended from relatively opposite side faces of the body, frame or block A and that the latter is provided with intermediate longitudinal ribs a upon opposite sides to form guides for the purpose of spac- Specification of Letters Patent.

ing the saw blade the selected distance from the frame or block A during either the trimming or swaging operations.

' Vertically slidably mounted upon one face of the body, frame or block A, with its upper lateral flange d having its ends beneath the inner portions of the upper edge strip B, is a gage clip D, the lower rounded portion of which is engaged by a flat spring E, the ends of which bear upon lugs c of the body, frame or block A, the spring tending to force the gage clip vertically and maintain its upper flange d tightlyagainst the lower ends of set screws 1) adjustably threaded through the inner portions of the strip B before mentioned, the said upper flange (Z of the gage clip having a longitudinal slot (Z to receive the raker teeth of a saw blade F therethrough, thus forming a gage for use in the operation of sharpening the saw teeth.

The gage clip D is guided in its vertical movement and adapted to be locked in adjusted position by means of a set screw G which works in a vertical slot (Z of the gage clip and is threaded through the body frame or block A for this purpose, its head bearing upon portions of thegage clip upon opposite sides of the slot (Z Above its slot (Z the gage clip is also provided with an outstanding lug (Z vertically through which is threaded a clamping screw H, adapted to engage and clamp a jointing file between the same and the lower surface of the flange (Z, such as shown in Fig. 2, the jointing file be ing shown in dotted lines and indicated at I. The other gage is disposed upon the opposite side of the body, frame or block A and consists of a flat tempered spring J secured for the major portion of its length along one part of the lower strip C, this spring having an inner free end projecting within the space between the inner ends of strips 0 and there being an adjusting screw 7 J threaded through the strip C to bear upthe gage spring J is secured, due to which the adjusting screw j may, by threading through the said overhanging portion of the strip, engage the gage spring J at a point much nearer the inner free end of this gage spring than would otherwise be p0ssible,0r is possible with devices of this character now in use. The effectiveness of the device used as a gage is by the aboveemeans, materially increased. Thus it will be seen that both the gaging clip and the gage spring are capable of quick and accurate adjustinent and permit of an unobstructed view at all timesof the Work being done, it being also 'apparentthat both devices may be readily removed from the body frame or block I either for repair or substitution.

I claim v In a device of the character described, the con'iblnatlon or" a body plate provided with a central cut out portion 1n one edge: and

having a laterally projecting bearing strip port-ions of which extend along its said edge uponopposite sides of its said cut-out portion, one of said portions of said strip having its inner extremity extending into the cut-outportion to form an overhang, agage consisting of a flat spring secured along said.

latter portion of the said bearing strip and I having a free inner flat end within the said cutout portion of thebody plate, extending beyond the over-hang of the bearing strip, and an adjusting screw threaded through the said overhanging portion of the bearing strip and bearing inwardly against the free R end of the spring, all for the purpose de- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Eatents;
