CROSSCUT-SAW TOOL.

Specification of Letters Patent.

Application filed 0ctober25, 1919. Serial No. 333,234.

To all whom it may concern Be it known that I, WILLARD A. SLOPER, a citizen of the United States, residing at Independence, in the county of Polk and State of Oregon, have invented new and useful Improvements in Crosscut Saw Tools, of which the following is a specification.

This invention relates to tools for working upon cross cut Saws for placing them in proper condition, and comprises a slngle tool which is a combination of all the tools required to properly dress a cross cut saw, including a jointer, raker tooth j ointer, raker tooth swaging gage, side file, set block, and set gage, arranged toafiord the greatest convenience to the saw filer.

An important object is the provision of a I device of this character which is provided with a clamping member so arrangedthat the file may be securely engaged with the device in a selected position whereby the points of the saw teeth may be filed or whereby the sides may be filed, the device having upon its sides ribs and the ribs on one side, the side upon which the file is disposable, serving as a guide whereby the file may be properly positioned for side filing, adjusting screws being provided for shifting the position of the file toward and away from the outermost edge of the guide rib.

Another object is the provision of a de vice of this character which will be simple and inexpensive in manufacture, which may be readily used by those understanding the art, and which will be very efficient and la bor saving in use, and -a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, andillustrated in the accompanying drawings in which Figure 1 is an edge elevation showing the device in use as a saw set, a

Fig. 8 is a cross sectional 88 of Fig. 7,

Fig. 9 is a cross sectional viewon the line 9-9 of Fig. 4, and

Fig. 10 is adetail sectional view, showing the means for adjusting the raker tooth jointer gage plate. Referring more particularly to the drawings, the numeral 15 designates the body of the device which is formed elongate in shape and which is provided at its center with longitudinally extending ribs 16 and which is provided upon one edge with flanges 17 having the same degree of extenview on the line sion beyond the body as the ribs 16. On

each side of the central ribs the body is cut away, as shown at18 and 19, to reduce the weight of the device and also to afford'fin 7 ger engaging means. One edge of the body has threaded therethrough a screw 20 which has its head extending withinthecut away portion 19 so that the head'may be grasped and turned for adjusting the and the latter of which passes through the plate 23 and into the body. By loosening the center screw 26 and then inserting a screw driver through the holes 27, the end screws 25 may be screwed out for moving the plate 23 away from the bottom of the recess, for. a purpose to be hereinafter'explained.

Extending from one end of the recess 22 to the adjacent end, the body is provided on both, sides with overhanging flanges 28. Formedupon or secured upon the edge of f the body and extending from the other end screw; Threaded transversely through the body heof the recess 22 to the other end of the body is a set bloclr 29 which has a hardened outer face and whlch has its edge adjacent the end of the recess beveled, as shown at 30. The

dened face of the set block 29 for gaging the pro or set to a saw tooth, as will be here'- ina ter explained.

Extending transversely through the guide portion of the set block 29 is a clamping memer 32 which has one end threaded and provided with an adjusting nut 33. The other end of this member 32 is refiexly bent, as shown, to provide a retaining lug 34 which is beveled upon both sides, as shown at 35 and 36.

In the operation of the device, referrin, to'Figs. 1 and 2, it will be seen that it is arranged for use in setting the teeth. \Vhen the device is to be used for this purpose it is positioned with they hardened face of the set block 29 against the saw, as clearly shown in'Figs. l and 2, with the point of the teeth disposed at the beveled surface 30. The operator then grasps a hammer and strikes a smart blow upon the tooth and bends it onto the beveled surface 30. After the tooth has been thus set and it is desired to ascertain whether or not the setting is uniform and proper, the device is moved into the position shown in Fig. 3, that is the hardened face of the set block 29 is disposed against the saw at a point farther away from the tooth to bring the gage pin 31 in such position that it will contact with the point of a tooth. When the tooth is properly set' the angularly bent point should just touch the en of the gage pin 31 while the saw is disposed perfectly fiat against the hardened outer face of the set block. If a tooth is found to have an insufficient set, the device is moved to the position shown in Figs. 1 and 2 and the tooth again struck with the hammer to bend it still more. If a tooth is found to have too much set the point instead of con-,

tacting with the point of the gage pin 31 will strike against the side thereof. In such an event the device is so moved that the tooth will be disposed against the plane hardened face of the set block 29, after which the operator strikes a blow upon the tooth with a hammer to flatten the tooth slightly. This operation is continued until the teeth are nated by the letter B and this file is arranged as shown in Figs. 4 and 9, that is the file is laid with one flat side engaging beneath the planed underside of the set block at one side of the body, this flat side of the file also engaging against the fiange 28 on the edge of the body at the same side thereof. It is understood that the clamping nut 33 is first loosened so that the clamping member 32 may be engaged upon the outer edge of the file, the lug 34 engaging against the other flat side of the file. The nut 33 is then tightened and owing to the beveled edge 35 of the lug 34, the file will be securely clamped upon the body. The operator then grasps the de- I vice in his hand and places it with the body against one side 'of the saw A and with the file disposed upon the points of the teeth, as clearly shown in Fig. 4. He then reciprocates the device and the file as one and in that way files down anyteeth which might be of excessive length, until eventually all the teeth are of the same length. d

-When the device is to be used for jointing V or dressing the raker teeth, the file is removed from in engagement with the body and the device is so positioned that a raker tooth extends through the slot 24 in the plate 23 with the body disposed against the side of the saw.

The operator then grasps the file in one hand the outer face of the plate 23 maybe regu-- lated, it being understood that when the de- Vice is used for jointing a raker tooth the adjacent teeth are disposed against the planed underside of the set block 29 and the underside of the flange 28 at the side of the body from which the plate 23 projects.

After a raker tooth has been thus jointed or dressed and it is desired to ascertain Whether or not the'rakertooth is of the proper length, which should be a trifle less than that of the cutting teeth, the device is disposed in the position shown in Fig. 6, that is it is placed with the edge opposite the setting block flat upon the points of the teeth at both sides of the raker tooth to be tested. The screw 20 is adjusted so that it will project beyond the edge of the body an extent equal to the proper distance between the length of a cutting tooth and a raker tooth. If the raker tooth has been properly dressed the point of the screw 20 will just contact with either point of the raker tooth. If the screw does not contact properly with the points of the raker tooth it is obvious that the raker tooth needs further dressing, in which event the previous'ly described operation is repeated.

After the teeth have been properly jointed or dressed and properly set, in order to 1n-- sure that the sides of the points of the teeth all lie in the same plane, the device is used as shown in Figs. 7 and 8. In order to accomplish this side dressing, use is again made of a file which is disposed against the side of the body opposite to that from which rib 16 and be consequently held firmly associated with the body. Thefile also engages upon a screw 40 which is adjustable to place the file in the right position. The operator then grasps the device and positions it as shown in Fig. with the under side of the set block 29 engaging upon the points of the teeth. When the device, together with the file, is then reciprocated, the sides'of the teeth will be filed so that they will all lie in the same plane. The provision of the screws 21 is an important feature as by their means it is possible to so adjust the file as to prevent excessive side filing of the teeth. It is obvious that when the screws 21 are screwed out partly, the active flat surface of the file will lie close to the plane of the rib 16 and flange 17 engaging against the side of the saw so that more extensive side filing will be accomplished than when the screws 21 are screwed in. It is believed that this feature will be clear without further explanation.

From the foregoing description and a' study of the drawings it will be apparent that I have thus provided a simple and compact device which combines in one implement all the functions of the various separate tools commonly used, and it will also be apparent that the device may be very quickly and easily adapted for use in its various capacities with the minimum expenditure of time and labor and with the maximum result in eificiency.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, 1 claim 1.
