SAW-FILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 728,893, dated MayA 26, 1903. Appleman flied rebmry 14.',1903. 'serial No. 143,344. (No modem T LZZ whom, it may concern:

Be it known that I, JOHN W. FOLEY, residing at Omaha, in the countyvof'Douglas and State of Nebraska, have invented certain useful Improvements in Saw-Filing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful improvement in saw-filing machines.

The aim of my invention is to provide a simple machine adapted to be secured to a suitable tripod, to the upper end of which is secured a panel supporting a table, which table supports a suitable'guide-shaft upon which is suitably held a carrier, which carrier in turn receives a vibrating file-holder, to which holder are adjustably secured a plurality of files. Y

In the accompanying drawings I have shown in Figure 1 an upper broken front view of a saw-filing machine embodying my invention. Fig. 2 discloses a top view thereof with portions removed. Fig. 3 discloses au enlarged detail disclosing 'the forward holder members. Fig. 4 shows a detail disclosing the rear file-holding members, while Fig. 5 shows an enlarged sectional view disclosing the vibrating holder as used in my invention. In carrying out the aim of my invention I use a rear foot 18, which by means of the hinges 17 is secured to a shelf C, and to this shelf is secured a panel B, to the top of whic is secured a table B. 1 Secured to the panel B and the shelf C ar the legs 19 19, secured by suitable cross-bars 20, so that by means of the legs 19. and foot 18 a tripod is provided which can be neatly folded up.

Secured to the shelf C by means of a holder K, provided lwith the ratchet-faced coupling 72, which coupling may be locked by means of the screw 7c, is an ordinary saw-vise A, this vise being used to secure the saw-blade which is to be filed, this vise being provided below with the usual set-screw 1b', securing the holder K and the front jaw member 14, secured by the usual lever a, Working within Y sharpened.

the ears '14, as shown. This vise forms no part of my invention, being an article sold upon the open market. The rear jaw A of this vise, as shown in Fig. 2, is held by means of the brackets e. Vertically and adjustably secured to the table B are the vertically-adj ustable threaded holders 2l, locked by means of the nuts 22, and these holders supporting the guide-shaft D, which shaft is shown in Fig. 1, and is approximately in line with the upper end of the vise.

. Extending from the table B are two supporting-arms b, provided with the notched lugs c, into which a saw may be inserted, these brackets b serving the'purpose of holding the saw or anumber of saws before the same are sharpened and after they have been In using this machine an operator, especially where meat-saws are being sharpened, oftenV has two or three saws to be sharpened, and the saws notv being operated upon are held upon the brackets b.

The guide-shaft D is slidably held within the holders 2l, so that this shaft may be moved sidewise, sliding within the holders 2l. Secured to this guide-shaft D by means of a screw 29, referring now to Fig. 5, is a bottom plate 28, slotted at suitable points, as 'shown'at 26. Secured to this bottom plate 28 are the roller-plates 12, suitably perforated to receive the trunnions of the rollersf, two such lower plates '12'being used, each plate supporting two sets of rollers. Secured above the lower plates 12 are the top plates lO, also perforated to receive the trunnions of the rollers f, and in order to hold these rollers suitable bolts are used, which pass through .collars 11 and through-the slots 26, so that these -bolts 25 un-ite the top and lower plates and collars and these"instrumentalities in be noticed that these roller-plates 10 and v12 and the rollers f are used in sets upon the `opposite sides, and the bolts 25 are securedvv IOO and M, in front secured to the block 9, (disclosed in detail in Fig. 3,) these arms L and M being secured by suitable pins and the screws t', as shown in Fig. 2.

The plate E, forming the vibrating holder, is provided with a slot, as shown in Fig. 2, adapted to receive the screw o', and a threaded opening adapted to receive the screw o, as shown in Fig. 4. The screw o is provided below with a revolubly-held collar 23, provided with an opening m'.

Striding the forward block 9 are the

adjustable straps

3 and 4. The strap 4 isheld upon the block by means of the tube 8', which extends from the strap 4 and enters a slot U within the block 9. In Fig. 3 the tube 8' is disclosed, as is also the vertically-positioned slot 'v This tube 8 formsa holder, which in front is adapted to receive the handle 8, as disclosed in Fig. 2. Positioned adjacent to the strap 4 is the strap 3, this strap also being provided with a tubular holder 7; but this holder 7 passes through a horizontal slot if, as shown in Fig. 3, and extending from the strap 3 is the loop 5, as shownin Figs. 2 and 3. These

straps

3 and 4 are made to tightly clamp the block 9. In orderto secure the strap 4, I provide the set-screw 9', (shown in Fig. 3,) which screws against the tube 8'. Extending through the strap 4 and into the tubeSisthele-holdingset-screw2. (Shown in Fig. 3.) Extending through the strap 3, block 9, and entering the tube is-the filleholding set-screw 1,. From this it Will be seen that the strap 4 is locked by means of the set-screw 9', while the strap 3, which cannot be vertically adjusted, may he laterally adjusted by means of the adjusting-screw 6. In order to secure the files necessary to sharpen the teeth to the vibrating holder, I insert the point of one saw-file, as V, into the opening of the set-screw o', while the remaining end of the file is inserted into the tube 8' and secured by the screw 2. The second le 2 has its forward end inserted into the opening 0c of the collar 23,While the handle end of the file 2 is secured within the tube 7 by means of the set-screw 1. A snitable handle Sis then secured to one of the holders 8' or 7. The les can then be nicely adjusted by means of the screws 0', while the forward end of the file maybe adjusted by means of the strap 4. The ile 2 is given proper adjustment by means ot' the screw o and the strap 3. In order that the screw o may be carried laterally from side to side, the same is made to pass through a block 5, as shown in Fig. 4, the block sliding within the slot j within the plate E, While the screw Works up and down in this block 5.

Now

screws o and o the iiles can be so adjusted vthat their cutting edges may be one-a little higher than the other, so that the second file will cut a little deeper than the rst le.

In the use of my saw-filing machine I secure the saw to be sharpened within the vise and then place the files upon the teeth and vibrate the plate E until I have filed down a suitable distance. Then by means of the handle 8 I advance the plateE, which is slidably held by means of the instru mentalities upon the shaft D,one tooth and again operate the plate E,so that each tooth that is operated upon by the first file is then engaged by the second file. From this it will be seen that I can more quickly and expeditiously' file a saw, for the reason that if it takes twelve strokes of a file to sharpen a tooth by means of my machine I need vibrate the files but six times, and so save half the labor required iu filing the saw under ordinary circumstances. The depth to which the files are carried and the number of strokes required are of course determined by the operator.

Now, having described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

A saw-tiling machine comprising the combination of the following instrumentalities, to wit.: a tripod, a table supported by said tripod, a vise secured to said tripod, vertically -adjustable holders secured to said table, a guide-shaft slidably held within said holders, a bottom plate secured to said shaft, roller-holding plate adjustably secured to said bottom-plate, upon opposite sides, rollers within said holding-plates, a plate forming a holder movably supported by said rollers, arms extending from said holder-plate, a block provided with a vertical and horizontal slot, secured to said arms, a screw provided with a {ile-holding opening laterallyladjnstable within said holder-plate, a screw provided with aloose collar secured to saidy holder-plate, said collar being provided with a file-holding opening, Va strap clamping said block and vertically adjustable thereon, a

Vfile-holder securedV to said strap, a second in presence of two witnesses.
