PATENT DAVID M. WILSON, OF KEMP, TEXAS.

SPECIFICATION forming part of Letters Patent NO. 601,191, dated March 22, 1898.

Application led'J une 25, 1897.

To all whom t may concern:

Be itk known thatI, DAVID M. WILSON, a citizen of the United States,residing at Kemp, in the county of Kaufman and State of Texas, have invented a new and useful Gin-Saw Filer, of which the following is a specification.

vMy invention relatesto gin-saw-filing machines, and has for its object to provide a compact and efficient mechanism'having direct means for communicating motion to the reciprocatory and rotary files and for removing the same from contact with the saw-teeth during the feeding of the saw, and, furthermore, to provide suitable means for adjusting the various parts of the mechanism to suit saws of different kinds and having teeth arranged at different intervals and beveled at different angles.

Further objects and advantages of this invention vwill appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of a saw-filing machine constructed in accordancey with my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a transverse section onthe line 3 3 of Fig. 1. Fig. 4 is detail view in perspective of the reciprocatory carrier detached. Fig. 5 is a similar view of the feed-lever-operating cam. Fig. 6 is a similar view of the iile-arm-displacing cam. Fig. 7 is a similar view of the gumming-le.

Similar numerals of reference indicate corresponding parts in all the igures of the drawings.

In reducing my invention to practice I have constructed a machine which is adapted to be applied to saws of a ginning or equivalent machine without removing said saws from under certain circumstances in order that the frame of the filer may rest' against the con- 'tiguousvertical portion of the frame of they seria-N0. 642,300.V (No model.)

ginning-machine. The construction of the machine embodying my invention, however, is such as to adapt it to -work with equal facility in all positions, and as it is desirable 'at times to dispose the filer in a horizontal position and support it at its rear end by means of trestles or the equivalents thereofvfor instance, as when theframe of the ginning-machine is not suited tosupport and guide the same-I have illustrated the machine in this position, a portion of a frame or trestle for supporting the rear end of the machine being indicated in dotted lines in Fig. 2.

The frame of the filer consists vof a plate 1, to which, contiguous to its rear end, are pivotally connected the rear ends of side arms 2, and said side arms terminate at their front ends in feet 3, which are adapted to be arranged upon opposite sides of a saw to be iled and to be seated upon'the contiguous spacing-blocks, whereby adjacent saws are held in their proper positions. The front and rear ends of these side arms are fitted in suitable guides 4:, formed in the contiguous portions of the supporting-plate 1, andthe front ends of the arms are secured at the desired adjustment, to vary the pitch of the supportingplate, by means of set-screws 5. By varying the pitch of the supporting-plate it is possible to adapt the machine for use in connec` tion with saws of which the teeth vary in pitch as well as saws of different diameters.

Mounted to slide upon the supporting-plate in suitable front and rear guides 6 and 7 is a carrier 8, provided at an intermediate point with a yoke 9, in which operates an eccentric 10, carried by an operating-shaft 11, which is mounted in bearings 12 and 13, formed, respectively, in the supporting-plate and in a fixed longitudinal bar 14, supported terminally by said guides 6 and 7. A crank 15, or other means for communicating motion to the mechanism, is fitted upon the operatingshaft 11.

Fixed to and adapted to be reciprocated by the carrier are file-carrying arms 16, preferably of spring metal and constructed to exert a constant inward pressure and resist outward deflection, the extremities of said arms being provided with iile-seats, which in the construction illustrated consist of keepers 17, adapted to receive the rear ends-of files 18 IOO and iitted with set-screws 19. lVedges 2O are adjustably iitted in the keepers when necessary to vary the angular positions of the files with relation to the file-carrying arms, said wedges being interposed between the files and the arms and being adapted to vary the inclination of the former by the amount of their insertion. I also preferably employ auxiliary spring-arms 2l, secured to the file-carrying arms and provided with adjustable pressurepins 22, consisting of setscrews or .their equivalents to impin ge against the outer sides of the file-carrying arms contiguous to their front ends and exert more or less pressure according to the adjustment. of the set-screws. It is obvious that the tension of the auxiliary spring-arms may be varied by the adjustment oi said set-screws.

In operation the rotation of the eccentric lO causes a reciprocatory movement of the carrier and a corresponding movement of the files 1S in contact with opposite sides of the saw-teeth; but in order to enable the reciprocatory files to be removed from contact with the saw-teeth at the limit of the rearward movement of the carrier and thus provide for feeding the saw to bring different teeth successively into operative position I provide the inner sides of the file-carrying arms with calnfaces 23 for cooperation with a iile-arm-displacing cam or block 2i, which is mounted for longitudinal adjustment upon the frame of the machine and is preferably secured at the-desired adjustment by means of a setscrew 25, extending through a longitudinal slot 26. It is obvious that by varying the adjustment of this cam-block 24 toward and from the front of the machine the point in the movement of the carrier at which the tiles are displaced laterally to release the sawteeth may be arranged to suit the conditions of operation and the diameter of the saw. The Iile carrying arms are preferably arranged in different planes, and hence in order to adapt the cam-block 24: to cooperate efficiently with both arms I have constructed it, as shown in Fig. G, with an ear 24, which projects toward the supporting-plate, and thus is arranged in the path of that file-carrying arm which is located contiguous to the plane of said plate.

In connection with the abovedescribed mechanism I also employ a gnmming-le 27, havinga spindle 2S disposed perpendicular to the plane of the supporting-plate l and having an attached pinion 29, with which meshes the teeth of a rack-bar 30, actuated by the carrier S. This rack-bar is formed on the front arm or slide 31 of the carrier, the latter being slotted, as shown at 32, to receive the pinion when the carrier is in its advanced position. The gummer, having a stationary spindle, whereby the le is incapable of reciprocatory movement to withdraw it from and advance it into engagement with the sawteeth I have provided it, in order to release the saw-teeth at intervals, with a flat or cutaway portion 33, which is of sufficient depth to allow the saw-teeth to pass when located in a forward position or contiguous to the saw.

The feeding devices which I prefer to employ in connection with the mechanism, as above described, embodies an intermediatelypivoted feed -lever 34, carrying a yielding tooth 35, pivotally mounted upon the lever and disposed at the opposite end in operative relation with a cam 3G, fixed to the operating-shaft ll, preferably upon the opposite side of the supporting-plate from the file-Carrying arms in order to be wholly independent thereof in operation. This cam is provided at one point with an enlargement 37, which when brought into operative relation with the contiguous end of they feed-lever moves the latter from the plane of the supporting-plate, and therebymoves the toothed end of the lever toward the plane of the plate to advance the saw the distance of one tooth in the direction indicated by the arrow thereon in Fig. 2.

It will be understood that the special construction of the iiles is immaterial to the essence of my invention; but the ordinary threecornered file is that which I have found to be particnlary eihcient in this connection, and hence I have shown the file-engaging keepers 17 of a construction adapted particularly for the reception of files of this class; but inasmuch as said keepers are detachablymonntcd upon the ends of the file-carrying arms it is obvious that they may be replaced by keepers adapted to the special form of file which it is desired to employ.

Furthermore, it will be seen that t-he operation of the carrier is directly dependent upon an eccentric carried by the driving-shaftlof the machine, thus dispensing with intermediate connections, and that the feeding-cam is likewise carried by and hence receives its motion directly from the operating-shaft.

It will be seen, furthermore, that as the reciprocatory files become worn after continued use the tension-screws 22 maybe adjusted to apply more or less pressure of the auxiliary spring-arms 2l and thus add to the pressure of the iile-carryin g arms toward the plane of the saw.

Various chances in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrilicin g any of the advantages of this invention.
