FILE CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 298,'71l=, dated May 13, 1884:.

No model.)

To all whom it may concern:

Be it known that I, CHARLES VoGnL, of Fort Lee, in the county of Bergen and State of New Jersey, have invented an Improvement in File- Cutting Machines, of which the following is a specification.

This invention is made for rendering the file-cutting mechanism available for various kinds of work, and for producing the most perfect work and with great rapidity.

I place the file upon an anvil or bed and pro vide a chisel or cutter sustained in a sliding stock and raised by a cam. The parts are adjustable, so that only one cam is used for dilferent depths of out, there being an adjustable rest upon the file-blank that determines the position of the cutter-stock with relation to the cam, the blow and depth of out being in creased in proportion to the height that the cam is allowed to lift the cutter and stock. The cutter is moved laterally as the cutting progresses, so that the file'blank is acted upon by a different portion of the cutting-edge each blow, and the entire width of the out ting-edge, or nearly so, is made. use of, and the cutter requires less sharpening and is worn uniformly. The cutter is raised by atreadle, and the feed thrown off simultaneously, so that the cutter-stock and cutter-head can be moved back without touching the file-blank, and there is astop to limit the backward move ment, so that the cutting is commenced with accuracy at the proper distance from the point of the file-blank.

In the drawings, Figure 1 is an elevation of the machine. Fig. 2 shows the back end of the cam-shaft and the joint for the cutterhead arm. Fig. 3 is the lifter-slide detached. Fig. 4. is a section at a: x of Fig. 1, in larger size. Fig. 5 shows the cutter-stock in section. Fig. 6 is a sectional plan at 1 yof Fig. 5. Fig.

7 is an elevation of the cutter-stock and section of the cutter-head. Fig. 8 is a sectional plan at the line 2 z of Fig. 4. Fig. 9 is a sectional plan at the line 00 x of Fig. 1. Fig. 10

at the head of which is the file-bed 0, upon which the file-blank a is laid; and it is held by any suitably gage and fingers, as usual in fileoutting machines.

In the drawings I have represented the cutter as operating upon one edge of a prismatic file-blank. This is usually done in making files ior sharpening saws. Vhen cutting the side of the prismatic blank, a holder with a V shaped groove is employed, as usual to hold the file-blank with its upper side parallel with the top of the file-bed 0.

Upon the bed A there are the bearings b, within which are received the tubular journals (6 of a yoke, D, that is provided with aradiusbar, E, which with the yoke can be swung back and forth upon its tubular journals Within the bearings b,- and there is a set-screw, c, passing through the yoke D and forming a stop against the bed, to limit the backward movement of the bar E and the cutter carried by it. At the upper end of this bar E there is a compound joint, F, connecting the arm G to the bar E. This joint F is made with a pivot-stud, (1, running down into a hole in the upper end of the radius-bar E, (see dotted lines, Fig. 2,) and the arm G is provided with a circular arm, cl, extending laterally from its rear end, through which the j0int-bolt a passes. (See the detached plan view, Fig. 10.) This arm G carries at its front end the cutterhead H, with the cutter-stock and cutter here inafter described. It also has a weight, G, by which the parts are steadied, and the file is held down by a rest, (1, at the cutter-head that presses upon the file a. It will nowbe understood that the cutter-head H can be moved lengthwise of the file-blank, in consequence of the bar E and its yoke turning in the bearings b, and the arm G, turning at itsjoint with the joint-block F; and there can be more or less of horizontal swinging motion given to the arm Gr and the cutter head, because the pivot of the joint-block F can turn in its socket at the upper end of the radius-bar E.

The main shaft 70 is in the tubular journals of the yoke D, and it is provided with fast and loose pulleys for the driving-belt, and with the pulley k for the feeding apparatus, and with the pulley k for the belt h, that extends up to the pulley h at the end of 4 a shaft, 71?, that is within the arm G, said arm being tubular or having bearings for such shaft; and there is a cam, i, at the end of the shaft it next to .the cutter-stock. This cam is revolved at a uniform speed, or nearly so, and it acts upon the toe-piece Z of the cutter-stock to raise the same, and as it clears the toe the spring Z projects the cutter-stock and cutter down with the required. momentum to cut the file.

The cutter-stock P is made to slide within the cutter-head H. The lower part of the stock is ribbed at" each edge, to slide in the head-pieces h", that project downwardly from the cutter-head, and are held together by the screw a, so as to prevent any looseness, but allow freedom of end motion to the out ter-stoek. The cutter m itself is a blade with a straight sharp edge held in the jaw-shaped end of the cutter-stock by a clamp-screw, 3. (See Fig. 5.)

At the side of the cutter-head H there is a side bar, N, which has an L-shaped head, through which the screw m passes, to adjust the bearing for the spring Z, so as to regulate the force of said spring, and the consequent power with which it projects the cutter-stock and cutter against the file-blank a. This bar Nis in a groove at the side of the head H, and it is held rigidly in its place by a bolt, to, that is made as seen by dotted lines'in Fig. 4:. The smaller part of the bolt passes through a holein N, and screws into the head H. The larger part of the bolt acts to clamp N to place, and it also forms a bolt in a slotted slide-lifter, if. The nut on this bolt it holds the slide a in place, but allows it to be raised and lowered, as hereinafter set forth.

I remark that it is preferable to make the upper part of the cutter-stock P circular and with an annular shoulder, against which the lower end of the spring Z rests.

At the lower part of the side bar, N, the rest 6 is fastened. This rest is .adjustable by the slot and clamping-screw 4. This rest extends out over the file-blank, and by it the cutter-head H-and arm G are supported, and the weight of the cutter-head and arm upon such rest serves to hold the file-blank down upon its bed. 1

It is to be borne in mind that under ordinary circumstances the cutter-stock P and cutterm are unsupp orted, except by the file-blank and the arm G, and other parts carried by it can be raised and lowered sufficiently for adj ustment without lifting the cutter. If the screw 4 is loosened and the cutter-head raised and the rest c again clamped to the'bar N, the shaft h and cam 13 will be raised toward the toe Z,- henee the cam, as it revolves, will lift the cutter a greater distance, and it falls a corresponding distance, giving a heavier blow and making a deeper cut in the file-blank. If the cutter-head is lowered in its relation to the rest 6, the reverse action takes place, as the shaft and cam are moved downwardly from the toe Z,- hence the cam raises the cutter a less distance, and a slighter blow and cut is given by said cutter It is to be understood that the cam i continues to revolve, and that the cutter drops as the cam clears the toe Z, but that the distance the cutter is raised and dropped varies according to the adjustment of the rest 0, because the shaft and cam are changed, as aforesaid, in their relation to the toe. The cutter, in falling, strikes on the blank and there remains until again raised, and the extent of the lifting motion depends upon the position of the shaft and cam to the toe. By this means one cam is made to give more or less stroke to the cutter, and the depth of cut is regulated to the greatest accuracy, and the out can be very fine or very deep, as desired.

From the pulley k a belt leads to the pulley L upon a shaft, 0, that is supported by the column B, and provided at the other end with a pinion, 0, which gives rotation to the feed gear-wheel p; and upon the axis of 1) there is a grooved feed-pulley, q. The feed-bar 1" is jointed at the back end to the radius-barE, and it lies upon the feed-pulley q. I prefer to make this feed-bar triangular, or approximately so 5 but it may be round or polygonal, and the pulley q should have a groove with inclined sides. It might, however, be a rounding groove. There is a lever, It, and weight S, the lever'being pivoted at s, and carrying a roller, 25, above the feed-bar 1", so that the weight will press the feed-bar firmly into contact with the feed-pulley q. As the feed-pulley is rotated, it will move the feed-bar, radiusbar, and

in the column B, for the shaft 0, said bushing being clamped by a nut at the end, so that it may be partially rotated and then firmly secured. This eccentric bushing 0 allows for the shaft 0 being brought nearer to or farther from the wheel 12, so that the pinion 0 may be changed, and the relative sizes and speeds of the pinion and feed-wheel 1) may be varied to change the distance between the cuts on the file-blank.

In order to stop the feed, I make use of a treadle, T, and vertical bar U, having a pin, 6, below the lever B, so that when the treadle is depressed the lever R will be raised and the feed-bar relieved from pressure by the roller 16; hence the feed will be stopped and the radius-bar, cutter-head, and cutter can be moved back or forward by hand, as may be necessary. In order, however, to prevent injury to the cut file, and to stop the cutting, it is necessary simultaneously to lift the cutter-head and cutter and hold them above the file-blank, out of the way of the same, so that one blank canbe moved and another introduced, or the blank be turned over. To effect this the rod U is continued 011 through the bed 0 to the lifterbar a, that is provided at the bottom of the groove a in the file-bed O, and there is a lifter, a", in a groove in the side of the bar N, which lifter is held in place by a nut on a bolt, if, said bolt passing loosely through a slot in N and screwing into head H, so that said lifter is free to slide vertically the length of said slot 5 and there is a pivoted block, a, at the bottom end of this lifter, running in the groove u, and resting upon the bar a. This groove might be parallel to the file; but it is preferably at an inclination, as shown in Fig. 6. Upon this lifter a there is a finger, a, that passes out beneath the lower end of the cutter -stock. WVhen the treadle T is depressed, the rod U raises the lifter-bar u bodily in the groove a, (the two being firmly connected,) and in so doing the lifter a is raised, said lifter sliding in its groove in the bar N, and the finger a first lifts the cutter-stock and raises the cutter off the file-blank. The movement thus given is sufficient to raise the toe, so that the cam t does not act upon it; hence the cutter is not moved by the continued rotation of said cam. The finger it moves in a slot in the lower part of the bar N, and upon the finger reaching the upper end of the slot, said finger lifts the bar N, rest (2, and cutter-head, at the same time that it lifts and supports the cutter-stock and cutter. By this arrangement of mechanism the shafts and pulleys continue to revolve while the cutter is raised and the file-blank changed or turned; but neither the feed nor the cutter cam is in active operation; hence unnecessary Wear is prevented.

As before remarked, the groove a is at an inclination to the file; hence, the block a" remaining in that groove whether the bar a is raised or not, the parts are guided as moved back or forth, and when the machine is in action cutting the file-blank the whole cutter-head and cutter are moved laterally, so that the cutting-edge of the cutter is moved in its relative position to the blank, and when the cutting is commenced the blank is beneath the cutter, near one end of the cutting-edge, and when the cutting is finished thefile-blank is beneath the cuttingedge, near the other end'thereof, thus insuring uniformity of wear and causing the cutting-edge to last longer without sharpening.

In place of the groove a,a rib might be provided, or the bar u might form such rib, the block it, having side pieces like a fork, passing down at each side of the bar a,- but the form shown is preferred.
