FILING-MACHINE.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed November 14, 1908. SerialNo. 462.557.

To all whom it may concern:

Be. it known that I. EUGENE C. BRULL. a citizen of the United States, and a resident of the city of Chicago, Cook county, Illinois, have invented certain new and useful Im- .provements in Filing-Machines; and I do hereby declare that the following is a full,

clear, and exact description of t-he same.` refvangle with reference to any other portion of the body operated upon. IVhere this has been done by hand. it frequently occurs that the slight rocking motion frequently occasioned in 'using the file or even slight differencesl in pressure unconsciously made by the operator result in varying the angle of the worki so vthat frequently a good fit is not secured although the utmost care is taken to secure the same.

rIhe object of this invention is to afford a filing machine adapted for use more particularly by model, tool and die makers,

though, of course, valuable for others and by the use of which any desired surface may be dressed to exactly the conformation and angle required.

It is also an object. of the invention to afford a machine of the class described in which a file may be set at any desired angle with reference to the work and table, or rather, the work table may be adjusted at any desired angle with reference to the cutting face of the file'.

It is alsjo an object of the invention tol afford a machine adapted to receive files of any desired shape or size, and provided with means wherein the throw or movement of the file may be accurately adjusted to afford a long or a short cut.

The invention embraces' many novel feaf tures and consists in the mattershereinafter described and more fully pointed out and defned'in the appended claims.

In the drawings: Figure 1 is a fragmentary vertical section of a machine embodyi ing my invention taken longitudinally of the driving shaft. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a section taken on lille 3 3 ofFig. l. Fig. 4 is an inner face view of the adjustable eccentric roller. Fig. 5 is a fragmentary face view of the file spindle with the head for the eccentric roller thereon. Fig. 6 is an enlarged fragmentary detail illustrating one of the adjusting means for the tilting table. Fig. 7 is an enlarged fragmentary detail of the bed illustrating the construction whereby tiles of any preferred shape may be used. though admitting small pieces of work to be approached as closely as may be desired thereto. Fig. 8 illustrates a modification for varying the angular adjustment of the table.

As shown in the drawings: said machine is constructed upon a frame, which though shown as a bench frame, lnay be of any desired' size and is indicated as a whole by A. and consists of a base n, and upper standard a., centrally apertured and affording a long apertured boss a2, in which isjonrnaled a main driven shaft B, provided with a belt pulley and as shown, secured if desired in a suitable anti-friction sleeve or bushing b. At its upper end -said standard is rahbeted at a right. angle with the shaft l. and also provided with a vertical groove. A vertically adjustable, section (1*, is engaged in the groove by means of a set screw b4, and slidably engaged therein by means of a set screw 712, is a segment 7:3, integral with the work table B, which may be constructed of cast metal.

J ournaled on the side of the section a4, is a pinion a3, which meshes with the mutilated gear or rack on thc seglnent b3, as shown in Figs. 2 and 6, and is provided with a slotted and angular head on its pintle or shaft adapted to be engaged by a wrench or screw driver, or other suitable tool to rotate the pinion, and thereby adjust the bed. As shown in Fig. 8, the segment b", (which corresponds to the segment b3) is provided with a worm and a worm gear bf, is provided for adjusting thesame. As shown, the section a4, and also the segmentV b3, are slotted to receive the set screw b2, therein, to facilitate the adjustment.

The bottom portion D, of the bed extends rearwardly from the standard a, as does also an arm d, above the same. Said bottom or base section and also said arm are each provided with an aperture therethrough in lwhich is secured an anti-friction bushing or sleeve cZ,-in which is slidably engaged the file actuating stem or shaft E. As shown also, the'work table B, in alinement with the apertures in said base and the arm d, is provided with an aperture therethrough, as shown in Figs. 1 and 7 of sufficient size to receive any tile that it may be desired to use, and set at whatsoever angle with reference to the angle Kthat may be required, and as shown, the metal about said aperture is trimmed away to afford a seat in which may be dropped a washer (Z2, having anaperture therein suitable for the tile employed. Thus by having different shaped bores therethrough a support for the work is afforded close to the file.

On the inner end of the shaft B, lis provided a face plate F, which is provided with a dove-tail seat extending diani'etrically across the same, 'and as shown, at'- each end of the groove thus afforded, is securedan upwardly and inwardly directed -metallic` plate f, which is apertured to receive a screw shaft f, thereon and slidable in said dovetailed groove is a carriage f3, through which said screw shaft has threaded connection and carried on said carriage or block f3, is a cam roller f4, which tits in a heade, which comprises, as shown, a horizontally grooved block rigidly `secured on a sleeve e4, extending centrally and transversely'thereof and through and iii which the file actuating stem E, extends -an-d is rigidly engaged by means 4of a, setscrew c.

The operation is Aas follows; The. suit-able file having' been selected, it is engaged in ythe seat or bore in the end lof the stem by means of thc set screw c5, and projects upwardly through the aperture in the tilting table B. A suitable washer is then dropped into place over the file carrying the bed up .close to the file. The table is now adjusted to the proper angle for the work required. This is vaccomplished by releasing the set screw b2, and actuating the pinion a3, or

` worm L6, by means of a wrench 0r other suitable tool', thus causing the table B', to swing thereon until the desired adjustment is attained, which may easily be accomplished with reference to the scaleon the segment, as shown in Fig. 2. The set screw is then adjusted to hold the table rigidly and the l operation may begin.

As the shaft B, rotates, the roller f4, moving in the traverse track e, therefor carried lon the file stem forcessaid stein to reciprocate with each rotation of the pulley and shaft B, thus enabling -very rapid motion to be attained. Should the extent or amplitude of the reciprocation desired vary, adjustment can very quickly be accomplished by means ofa threaded shaft f, one end of which is slotted to receive a screw drive, and

'the other end of which is shaped to receive a wrench. Adjustment in one direction obviously moves :the cam rollertoward thek center while rotation inl the'opposite direction obviously moves the same toward the periphery of the 'face plate F, affording a longer throw. An almost infinite variety of adjustments as to angle may be secured dependent upon the arrangement 'I of the le in the stem E, and it is possible to so adjust the file with reference to the table as to afford any angular cut desired.

Of course, I am aware that struction may be varied. I therefore do details of connot purpose limiting nyself otherwise than necessitated by the prior art.

I claim as my invention:

l. A filing machine, comprising a table, a toothed segment secured to said table, a support, means on said support for slidably receiving said segment and forming the sole support for the same, and a gear for oscillating said segment in'said support.

2. A filing machine', comprising la frame, a standard vertically adjustable in said. frame and having a curved groove in its top, a table,y a toothed segment secured to said table and fitting in'said groove the same forming the sole support for said table, and

a gear journaled in said standard and meshing with the teeth on said segment to oscillate said table to'vaiy the adjustment thereof.

3. A filing machine, comprising a frame, a vertically adjustable standard secured thereto, said standard having a curved groove in its top' and a slot opening into said groove,

a table, a toothed segment fixed to said tabley and engaged in said groove to form the sole support for said table, a set screw extending through said slot and engaging said segment to limit the vadjustment of. said segment, and a gear meshingwith the teeth of said segment `for adjusting'the table.

In testimony whereof lI have hereunto subscribed my namein the presence of two subscribing witnesses.

EUGENE c. BRUEL.
