SAW FILING AND SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 615,280, dated December 6, 1898.

Application filed October 30, 1897- Serial No. 656,912. (No model.)

will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for sharpening and setting saws; and it consists of certain novel constructions, combinations, and arrangements of parts, al1 of which will be hereinafter more particularly set forth and claimed.Y

In the accompanying drawings, forming part of this specification, Figure 1 represents a side elevation of the machine embodying my invention. Fig. 2 represents a top plan view of the same. Fig. 3 represents a side elevation taken on the side opposite from that shown in Fig. l, and Fig. 4 represents a front elevation of my said improved machine. Fig. 5 is a top plan view of the table and the feeding mechanism, a portion of the table being removed to better illustrate the construction Fig. 6 is a detail rying antifriction-rollers. Fig. 7 is an edge elevation of the feeding-disk and segment.

1 in the drawings representsv the base of my improved saw Sharpener and setter; 2, the supporting-frame mounted thereon; 3 3, the setting-lever; 4, the saw-supporting table; 5, the iile-operating lever, and 6 the le-holder. Said frame 2 comprises two vertical-spaced parallel plates 7 7 and curved table-supporting plates 8 8, suitably bolted to the forward ends of the same. The said plates 7 7 form a support for the main power-shaft 9, upon the outer end of which is mounted a balancewheel l0, carrying an operating-handle 1l. Said shaftv 9 further carries two cams 12 and 13, respectively, secured side by side thereon. These cams are adapted to engage adjustable blocks 14, mounted in the rear ends of the respective setting-levers 3 3 and adapted to be adj usted in their relation to said levers by set-bolts 15, that pass th rough said levers and engage said blocks.

A coil-spring 16 has its respective opposite ends connected by screw-bolts 17, mounted in the yrespective ends of the levers 3 3, so as to normally draw the ends of said levers together.` Said levers 3 3are pivoted upon an auxiliary shaft 1S, mounted upon the frame 2, and are held normally together in contact with each other.

Setting-dies 2O 20 are mounted in the respective forward ends of the levers 3 3 by means of screw-bolts 21, which pass through said levers and engage said dies. These dies are so arranged that while one of the same strikes a tooth up the other forces the adjoining tooth down, and thus equalizes the shock to the blade and prevents the edge of `said blade being-bent either up or down by a constant pounding in one direction only. This peculiar arrangement of dies and the relative arrangement of the cams 12 and 13 cause the forward ends of the levers 3 3 to be brought together once upon each revolution of the main power-shaft, so that said dies are simultaneouslybrought into contact with the saw-teeth.

A transverse shaft 22 is journaled in the frame 2 and is provided between the respective plates of said frame with a gear-wheel 23, which latter meshes with a gear-wheel 24, fast on the main power-shaft 9. Said shaft 22 is provided at its outer end'with a crank portion 25, which projects through an elongated slot 26, formed in thev rearwardly-projecting portion of the lever 5. Said lever 5 is journaled,- as at 26', upon one of the plates of the frame 2, and has formed at its forward end an `elongated slot 27, through which passes a pin or bolt 28. This latter engages a slide 29, mounted in vertical guides 30, secured to the base l, so that as said lever 5 is oscillated by the movements of the crank 25 said slide will be moved up and down. Said slide 29 carries an adjustable horizontal arm 3l,forrned with a slot 32,through which passes a securing-bolt 33, whereby said arm may be moved in and out at will. The other end of said arm is bifurcated and formed into a split journaled portion 34, in which is mounted the journal 35 of the iile-support 3G. This latter is formed with a socket 37, into which the lower end of the iile is secured by means of a bolt 38 passing through the wall of said IOO support. This socket 37 is three-cornered,

also the stock of the file, so that the operator after one edge of the iile is dull can turn the iile around to the neXt edge and the file will stand in the same position as before. A spring 39 is suitably secured upon the arm 3l and is provided at its upper end with an aperture 40, adapted to receive the upper end of the iile 4l. By this means said file 4l is pressed forward under spring tension and may yield backward when necessary to relieve any excessive friction between it and the sawteeth. The said gear-wheel 24 is adapted tol mesh with a gear-wheel 42, mounted loosely upon the shaft 1S, which in turn meshes with a gear-wheel 43, mounted upon a shaft 44, to which is secured the feeding-segment 46, having threads on its end which are diagonally disposed, and also the guide or disk 45 with an offset. The circumference of said disk 45 has an offset which is disposed obliquely to the face of the disk, and this offset is designed to engage with a tooth of the saw at each revolution of the said disk for the purpose of advancing the saw the distance of one tooth. The oblique threads on the segment 46 are provided to also engage with the teeth of the saw to make the feeding sure in casev the oft'- set of the disk 45 happened to fail to feed the saw by reason of a broken tooth coming opposite the offset. After the saw has been advanced by the offset the periphery of the disk bears against the edge of the tooth and steadies the same until the saw is ready to be fedforward again, which will occur each time the disk makes a revolution. Said saw 47 is supported upon the table 4, which latter is mounted upon the supporting portion 8 of the frame. This table is mounted to slide horizontally on the support 49 and has a depending portion 57, thro ugh which the threaded bolt 58 passes, whereby as the hand-wheel 61, which is keyed to theend of said bolt 58, is turned in one direction or another the tension of the spring 49, interposed between the depending portion 57 and the outer portion of the frame, may be regulated and the table may be moved backward and forward to adjust it to the width of saw being set and iiled. Pivoted to the sliding table 4 at 4X, on the edge thereof, is the plate 75, which is adapted to swing back to allow the saw to be placed under the free edge of the plate. In order to hold the plate down, the thumbscrew 52 is provided, which has its lower end threaded and engages in a threaded aperture 7l in the table, and interposed between the plate and the head of the said screw is a spring 53, and by raising or lowering the screw the tension of the spring 53 is regulated. Mounted on the top of the table is a block 76, which is apertured at 77, and said block carries on its inner edge a series of antifrictionrollers 55, against which the rear edge of the saw being set and filed is designed to bear. At the rear of said block and loosely held on the table-top is the wedge 7 S, which is provided with a longitudinal aperture 7 9,through which the thumb screw 80 passes. This wedge is provided to adj ust the block by forcing it toward the rear edge of thek saw, and when adjusted the thumb-screw 8O may be tightened and the wedge held in a fixed position.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-
