SAW-FILER.

SPECIFICATIONforming part of Letters Patent No. 753,575, dated March 1, 1904.

Application filed July 2, 1903. Serial No. 164,094. (No model.)

Be it known that I, JOHN M. HOLLADAY, a citizen of the United States, and a resident of Holladay, in thecounty of Spottsylvania and State of Virginia, have invented a Saw-A Filer, of which the following is a specification.

This invention relates 'to improvements in saw-filers; and the main objects in view are to produce a simple and economically-constructed device adapted to be readily and securely clamped on circular saws in proper re- -lation with the teeth thereof, which will accurately and positively guide and regulate the le in its operation of vsharpening said teeth, which when once adjusted to the pitch of the teeth may be subsequently moved to and throughout the succession of teeth, and which is equally adapted for the ling of the chisel or both right and left hand briar teeth;

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out ,in the claims. A

Referring to the drawings, Figure 1 is al side elevation, and Fig. 2 an edge elevation, of the preferred form of saw-filer, the former ligure showing the saw to be operated upon in dotted lines. Fig. 3 is a side elevation of a modified form, and Fig. 4L a top plan view of the same. Fig. 5 is an elevation similar to Fig. 1, illustrating a modification; and Fig. 6 is a plan thereof. Figs. 7, 8, and 9 are de-0 tails hereinafter referred to in connection with Fig. 5. Fig. lO-is a plan view of- Fig. 11, and Fig. 11 is an elevation of a still fur- .ther modification hereinafter referred to.

Fig. 12 is an edge elevation of Fig. 1.1,. Fig. 13 is a detail hereinafter-referred to. y

Similar numerals of reference indicate similar parts in all the gures ofthedrawings.

My device, which I term a saw-filer, comprises in each instance illustrated a pair of clamping-plates 1 and 2, the two being perforated in transverse alinement. The two plates are designed to clamp upon a circular saw, and in order that the clamping may be readily accomplished as the device is moved from point to point of the saw to operate successively upon its teeth I preferably employ in each instance a connecting-bolt 3, which passes through the two plates 1 and 2 and which at one end may be provided with an ordinary thumb-nut, or, as shown, with a ratchet-nut 4:, the teeth of which are caused to engage and interlock with a toothed Washer '5. Upon the bolt 3 between the clampingplates 1 and 2 I may locate an expansive coiled spring 6 to normally spread or separate the two clamping-plates as far as the bolt and nut will permit.

i Referring more particularly to Figs. 1 and 2, it will be seen that I extend the upper rear corner of the clamping-plate 2 above its companion 1, thus forming a short ear 7, and upon a transverse pintle 8, passed therethrough, I loosely mount the rear end of an arm 9, of irregular shape, and which may have formed in its under side, near its front and free end, one or aplurality of notches-in this instance two-and designated as front and rear notches 10 and l1, respectively. In this instance, asin all other forms shown, the clamping-plate 2 has adjustably mounted thereon, by means of a bolt 12 and set-nut 13,V a .rear gage-arm 14.

Yieldingly mounted on a bolt or stud 15, extending from the face of the clamping-plate 2, is an upwardly-disposed vibratory arm 16, which may pass loosely through a keeper 22 and terminate at its upper end in anv arch 17, bridging over the upper ends of the two clamping-plates. Horizontal and parallel terminals 18 may extend forwardly from the arch, and rising from each may be any suitable design of file guide. I prefer, however, opposite pairsof pins 1-9, each carrying a loose sleeve or roller 20. These pins and rollers may be arranged as shown in Figs. 1 and 2 or as in Fig. i-that is, with two or four pins and rollersthe iirst instance adapting the device for guiding and gaging a file while operating on a saw having chisel teeth only and in the second instance adapting the device for guiding and gaging a iile while operating on a saw having either right and left briar teeth or both briar and chisel teeth, all as hereinafter apparent.

A flat or other form of spring 21 may be let into a post formed on the face of the clamp- IOO ing-plate 2 and at its free end bear against the arm 16, which for convenience I will term the carrier-arm in that it carries the {ile-guides. By this means the carrier-arm is yieldingly pressed forward, being limited and guided in its movement by the keeper 22, in one end of which may be located a set-screw or stop 23, the latter limiting the rearward movement of the arm.

From the front upper end of the clampingplate 2 rises a locking-standard 24, the same having an overhanging shoulder 25, above which the standard is rounded off or beveled. This shoulder 25 overhangs the path of the arm 9, whereby the arm when depressed is sprung into and engaged by the shoulder and temporarily locked in a depressed position.

This completes the description of my preferred form of saw-filer, and the operation of the same may be briefly outlined as follows: The nut 4 having been loosened, the clampingplates spring' apart and are set astraddle of the saw. (See dotted lines, Fig. 1.) When this is done, the notch 10, if it is a briar tooth, or the rear notch 11, if it is a chisel tooth, that is to be filed, will engage with said tooth. The device as a whole is then given the desired inclination, and when so adjusted the tail of the arm 14 is lowered until it rests on the end of the next succeeding rear tooth,

after which the nut 13 is tightened. The

arm 14 may be of other shape than that shown and may rest on any part of the saw and not necessarily the point of the tooth. Having thus adjusted the parts the clamping-jaws are now closed tightly and by means of the nut4 and bolt 3 are caused to tightly embrace the saw. The front gage-arm 9 is now thrown to the rear and out of engagement with the tooth to be filed. (See Fig. l.) If the tooth be of the chisel style, the lile is run back and forth across the front faces of the two rear rollers or sleeves 20, the latter being pressed backward, and thus yielding to the pressure of the file against the tendency of the spring 21. rIhis backward movement of the guides will of course be limited by the set-screw 23, against which the carrier-arm 16 abuts eventually. Having led this tooth, which it will be seen can be accomplished by unskilled labor, the arm 9 is again thrown into engagement with notch 25 of the standard 24, the

' nut 4 loosened, the plates l and 2 separated by the spring 6, and the device advanced to the next tooth. When thus advanced, the rear notch 11 of the arm 9 is engaged with the tooth to be filed, the device lowered until the rear gage 14 rests on the tooth last filed, and

' the nut 4 again tightened to clamp the device in position. The arm 9 is then released and swung back out of the way and the tooth filed as before. In case it is a briar tooth that is to be filed the operation is the same, except that the front notch 10 is engaged over the In Figs. 3 and 4 I have shown a slightly- 4 modified construction. In this instance the upper end of clamping-plate 2 is linished on? flat on its upper end and at its rear side provvided with a depending lug 26, having a transverse perforation 27. A horizontal plate 28 is mountedon the clamping-plate 2 and is adjustably swiveled thereon by means of a bolt 29, having a` clamping-nut on its lower end. The plate 28 at its rear end extends beyond the plate 2 and is formed with a depending flange 30, having a central hole 31 and at either side thereof a hole 32. (See Fig. 4.) A U-shaped spring-catch 33 has one terminal let into the rear edge of the clamping-plate 2 and its other terminal laterally disposed, as at 34,

passed through the perforation 27 and may be temporarily` engaged with either of the holes 31 or 32. By loosening the nut on the bolt 29 the plate 28 may be set at either angle or parallel to plate 2 and so held by spring-4 catch 33 and subsequently tightly secured by the nut on bolt 29. Rising from the plate 28 is a standard or ear 35, and pivoted therein `by the pintle 8 is the arm 9, which in this instance may be provided with a single notch 36. From the front end of the plate 28 there rises the heretofore-described notched locking-standard 24. The rear edge of the standard 35 and standard 24 are slotted, as at 37, and normally mounted within the same is a guide-frame-carrying plate 38, from the forward end of which there extends a slightlydepressed yoke-shaped guide 39, from which in this instance rises a pair of transverselyopposite pins 19, each having a loose sleeve 20. Acurved spring 40, interposed between the standard 35 and plate 38, serves to yieldingly force the latter forward. It will be observed that in this instance the main point of difference is that the carrier 38 is slidably mounted instead of pivotally mounted, as here'- inbefore described.

Referring more particularly to Figs. 5, 6, and 8, it will be noted that both the carrier 41 and front gage-lever 9 are mounted on the pintle 8 of the standard 7. The device herein illustrated is intended for that class of lighter circular saws employing the usual form of saw-teeth, and the carrier 41 is preferably mounted, as shown, and divided at its front to form the yoke 43, at the extremities of which are supported the downwardly-inclined IOO IIO

guides 20. This carrier is further'provided with an opening 42, upwardly through which' projects the locking-standard 24, having the"y the lug 7 1, the latter rising from a plate 47,

widened at its rear end and having a segmental slot 48, through which projects from a similar extension 49, formed on the clamping-plate 2, a bolt 50, carrying at its upper end a winged nut 51. (See Figs. 7 and 9.) The carrier in this instance is swiveled on the standard 24, which is made cylindrical, (see Figs. and 6,) and hence maybe given any necessary angle and secured by the nut 51 in the adjusted position, whereby bevels may be iled, if necessary.

Referring to Figs. 10 to 13, it will be seen that the main difference resides in the means of attaching the guides on the carrier and arranging for their adjustment. In this instance one of the guides 2O is fXedly mounted on one arm of the carrier-frame 17a, while the companion guide is adjustably mounted on the opposite arm thereof. This matter of adjustment may differ, and I have illustrated in the figures referred to two convenient ways. In Fig. 13 I show the carrier-arm slotted longitudinally, as at 52, the post 19 mounted in the slot and held by a nut 53. Another convenient way is illustrated in Figs 11 and 12, wherein one of the carrierarms is formed ,with a rib 54, engaged by an opposing rib or flange 55, formed at the inner edge of an inverted-L-shaped plate 56. The vertical liange of the latter is slotted, as at 57, and projecting outward through the slot from a block 58, inclosed by the plate 56, is threaded stem 59, upon which is mounted a milled nut 60.
