ELIVIER E. Il/IOHNEY, OF FRESNO, CALIFORNIA. l

SAW-GAGE.

Application led January 17, 1916.

T 0 all whom it may concern: i

Be it known that I, ELMER E: MOHNEY, a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, h-ave invented new and useitul Improvements in Saw-Gages, of which the following is a specification.

The present invention relates to improvements in saw filing gages.

An object of the invent-ion is to provide a gage which may be used in shaving as well as iling the raker teeth of a saw and in which a movable member may be adjusted at different heights to suit the character of the teeth to which it is applied.

A further object of the invention is to provide a device of this character with a sliding member in the nature of a gage whereby the proper height of the raker teeth may be determined without necessitating the operator using his eyes for such purpose.

Vith the above and other objects in view, the, improvement resides in the construction, combination and arrangement of parts set forth in the following specication and falling within the scope of the appended claims.

In the drawings: Figure 1 is a front elew vation of my invention, Fig. 2 is a rear eletation of the same with the saw in position, Fig. 3 is an end view of the device, Fig. 1 is a top plan view of the device, Fig. 5 is a sectional view' approximately on the line 5 5 of Fig. 1, Fig. 6 is a horizontal sectional view approximately on the line 6-.6 of Fig. 1, Fig. 7 is a sectional view approximately on the line 7 7 of Fig. 1, Fig. 8

a perspective view of the gage member,

Fig. 9 is a similar view of thetace plate for the frame, Figs. 10 and llare detail perspective views of the blocks attached to the face plate, and Fig. 12 is a perspective view of the sliding gage member.

In the drawings the numeral 1 designates the frame which may be in the nature of a flatplate and which has its upper edge formed with an annular flange 2 providing the top or cap of the plate and this top is channeled longitudinally, as at 3, to receive a substantially rectangular plate or strip L1 of hardened material, the same being retained in the chamber by screws 5. The strip l serves as the contact member for the teeth of the saw. The frame, upon its inner face is provided with a pair of longitudinally extending spaced ribs 6 and 7 Specicaton of Letters Patent.

-the in ner faces of which being straight and n a line and it is against these ribs that the face or side of the saw abut's.

The frame 1 is notched centrally from its top, the said notch for a suitable distance 'below the top or cap 2 being closed by a guide 9, and the plate 8 from the upper edge is provided with notches whose opposite walls are beveled or inclined, as at 10, inwardly from the top of the said plate, the

beveled walls communicating with a vertidisposed substantially rectangular opening 11 in the said plate S. Secured upon the outer face of the plate 8 below the -rectangular opening 11 therein is a ,block 12, and also secured upon the said outer tace of the plate to straddle the lower portion -of the substantially V-shaped notch and partially close the upper portion of the i opening 11 is a second block 13. This block 13 has its lower face provided with a substantially rectangular depression 14.

The gage is indicated by the numeral 15 and comprises a substantially rectangular member disposed to be snugly received in the substantially L-shaped guides 9 of the plate 10 and having its lower edge provided with an outwardly extending centrally disposed lug 16 which is adapted to be received in the opening 11 of vthe plate 10, and if necessary, to contact with the side walls provided by the said opening. The lug has a threaded orilice 17 to receive the upper end of agage screw 18 which passes through an opening in the block 12 and which is provided with collars 19 and 20 contacting with the opposite faces of the block to permit of the free rotation of the screw in the block.

' The collar 20 is provided with a similar indicating mark 21 upon the outer face of the block 12, and the threads of the screw are so cut as to indicate the elevation of the gagel 23 which is notched at its ends, as at 24C, to receive the inwardly extending portions of the L-shaped guides 9. The body of the plate, at its upper edge, is formed centrally with notches as is the central portion of the shelf 23 providing the body as well as the inner edges of the shelves with vertically extending parallel side walls 24: which have their outer edges beveled outwardly or toward the ends of the gage, as indicated by the numerals 25. Extending centrally throughthe notch formed integral with the body of the gage is a substantially rectangular block 26 which is centrally formed with a square lug 27 and which is beveled from its opposite corners inwardly to the said lug, as indicated by the numerals 28. The inclined surfaces 28 are arranged at an angle from the upper corners of the beveled portions 25 or in a direct line with the juncture of the said beveled corners and the top of the gage proper, so that a lile resting upon either of the surfaces 28 will contact with the gage at the mentioned corners.

The numerals 29 designate the slide members one of which resting upon each of the shelves 23. Each of the slides includes a substantially rectangular body portion 30 which is reduced on one of its sides for the major portion of its length, the said reduced portion having an elongated slot 31 through which passes a guide screw 32 that enters the inner face of each of the shelves 23. The forward and enlarged portions of the body of each of the slides 29 has its end beveled, as at 33, the bevel of the said ends equaling the beveled portions 25 of the cage proper, and each of the members 29 is provided with an upstanding thumb piece 311, whereby the same may be moved longitudinally over the shelves to permit of its beveled edge registering with the beveled corners 25 of the shelves 23, or whereby the members 29 may be spread over the notched portion of the gage.

As previously stated, the saw 35 is arranged to contact with the ribs G and 7 to have its teeth contact with the strips 4. By working the slide members 29 over either of the shelves 23 of the gage member the operator can determine the height of the raker teeth without bending to see the exact position of the raker teeth with relation to the gage, as it will be apparent that along raker tooth will be contacted by the slide and a tooth not long enough to be operated on will not be contacted by the slide. A raker tooth is arranged in the notched portion in the top of the catch 15 and its end is bent over the corners 25 of the shelves 23 by the impact of force such as the blow of a small hammer. rlhe file is then arranged upon the inclined surfaces 28 and operated until the said le rests upon the upper corners provided bv the said portions 25 and the surfaces of the portions 28. rThis, it will be noted, prevents the file from cutting too much over the tooth and also permits all of the said teeth being swaged and filed at the same angle and at the same length. llfhe lug il is arranged in a line with the shelves 23 so that should it be desired to cut the ralrer teeth straight 'off the vlile can be operated in a line with the upper edge of said lug and the upper surfaces of the shelves.

The screw member 18 is adapted to be locked in its adjusted position through the medium of an adjustable binding element 50. llfhe element 50 is preferably in the nature of a screw, and is engaged in a threaded opening in the block 12 which communi- Cates with the opening through which the screw passes.

From the above description, taken in cona nection with the accompanying drawings, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what 1 claim is:
