To @ZZ whom it may concern:

Be it known that I, JOSEPH ANGUs, a sub' ject of the Queen of Great Britain, residing at South Lambeth, in the county of Surrey, England, have invented certain Improvements in Tool-Holders for Metal-Planing Machines and in Mechanism for Operating Same, of which ward and one on the back stroke-partly in the tool-holder, where the tool is arranged to cut both ways, and partly in the mechanism for shifting the tool and its holder.

In the drawings, which serve to illustrate my invention, Figure l is a fragmentary vertical section of the tool-bar of a planer on the line l 1 of Fig. 2. Fig. 2 is a horizontal section of the tool -bar on the line 2 2 in Fig. l. Fig. 3 is a detached view of the operating rod or shaft. Fig. 4 is a sectional elevation ofthe tool bar and holder ofa planing-machine detached, showing the mechanism for actuating the tool-holder. Fig. 5 is a detached plan view of an operating-rod and cam shown in Fig. 4:. Fig. 6 is a fragmentary front elevation of the tool-holder, and Fig. 7 is a plan of the same. Fig. 8 is a plan and transverse section showing the adaptation of my improvements toa planing-machine wherein the tool moves over the work. Figs. 9, 10, 11, l2 are detached views illustrating modified constructions of the mechanism for reversingthe toolholder.

Referring to Figs. l to 7, inclusive, Q is the tool-bar, xed to the frame of the machine in the usual way, and L is a socket-piece, mounted so as to be adjustable on its axis in a bore or recess at the lower end of the same, being provided with a cylindrical shank, a, iiange or shoulder b, tail-pin c,- and ordinary nut, lock-nut, and washer, as shown. socket-piece L is mounted, so as to rock on its axis, a tool-holder, N, the axis of which crosses vthe axis of the socket-piece at right angles.

In the saidF (No model.) Patented in England March 13,1880, No. 1,091.

The projecting ends of the tool l? move in slots n in the socket-piece L, the sides of which slots Vlimit the rocking of the tool to the extent required. Vhen the tool is cutting, it bears against the socket-piece L on both sides of the holder N, as shown by dotted lines in Fig. 4', and thus the strain produced by the cutting is removed from the holder, which greatly enhances its durability, the permanence of its adjustment, and the accuracy ofthe Work produced. Then the tool has cut across the work and reached the end of its forward stroke, the tool-holder N is rocked and the tool thereby reversed, ready to cut the metal on the 'return-V stroke, and then the tool-holder is again rocked and the tool reversed in the same manner as I before, whereby the cutting is effected in both directions instead of one direction only, as in ordinary machines, thus doing double the work of an ordinary machine.

The mechanism for automatically reversing the tool at the end of its stroke may be constructed in several ways, being varied slightly according to the style of planer; but the preferred form is best shown in Figs. 1 to 7, and that I will now describe.

On the shank a of the socket-piece L is mounted a sliding collar, K, which has a lim ited play endwise on said shank; and to this collar is fixed a hook-rod, O, the hooked end of which is arranged to engage a recess in a flange on the tool-holder N. By means of this rod O, the sliding of the collar K back and forth rocks the tool-holder and reverses the tool. The collar K is provided with a circumferential groo've,and in this groove rest arms J J, which branch laterally from a vertically-arranged operating-rod, I, (see Fig. 3,) mounted so that it may be rocked on its axis in a groove in the tool-bar Q, its upper end being retained in place by means of a. bearingblock, x. Oscillation of the rod I on its axis reciprocates the sliding collar K, and this movement is not in any way affected by the turning ofthe socket-piece L in its bearings, as the arms J engage the circumferential ICO groove in whatever position the collar may be ,placed by adjustment of the socket on its axis. The cylindrical plug or buffer in use in an ordinary planing-machine,which forms a part of the tool-relieving gear, and ordinary singie-acting cam and spindle for lifting the ordinary tool during the ordinary back-stroke, are removed, and their place in the center of the machine-slide is supplied by a speciallyro designed double-acting cam, B, Figs. l and 5, which is fitted with a feathered key, so as to slide vertically on the usual relief-spindle, A, and a. strap or wiper-box, C, the stem G/of which passes through the aperture in the machine-saddle previously occupied by the plug or buffer before mentioned, and enters a cylindrical box or cylinder, E, within which the said stem terminates in a screw, on which is fitted a collar, D, within the said cylinder E, 2o which plays in a hole in the cast-iron strapblock ofthe machine-slide head to which the ordinary tool is usually secured, and into the forward end ofthe said cylinder E is screwed a slide-piece, F.

To secure a yielding connection between the stem C and the sliding pieceF, and to provide means for adjusting the parts so that the cam B may properly roek the tool-holder, the space wit-hin the cylinder E behind and in front of 3e the collar D may be taken up with spiral springs, adjusting-screws, or by leather packing G, as shown in Fig. .L. By this means breakage of the hook-rod O is prevented, and the tool-bar Q is thus enabled to be adjusted 3 5 to any angle in a vertical plane. The slide F reciproeates in a slot, XV, in the tool-bar, and has a notch or recess in its upper edge to engage an arm, H, on the operating-rod I.

The operation of the parts described is as 4o follows: In the ordinary operation of the machine, when the planer-bed has reached the end ot' its stroke or movement, it strikes a tappet, which turns the relief-spindle A about a quarter of a revolution. By this movement of the existing spindle in such a machine, one point of the double cam B, turning with it, moves the slide F through the connectingparts C, C', D, and E. The movement of the slide F acts through the arm H, operating- 5o rod I, arms J J, collar K, and hook-rod O, to oscillate the tool-holder N and reverse the tool for the next cut. As the bed moves to the other end of its stroke, the tool is again reversed by the opposite point of the cam B, thus enabling thc double-cutting tool to cut on the return as well as on the forward stroke. The peculiar advantages of my construction above described are that the tool-bar Q and its appendages may be turned completely 6o around in a vertical plane onthe collar D as a center, and be placed to work at any angle desired lwith the bed of the machine, while the wiper-box C maintains its proper horizontal position, as shown. The socket for the tool-holder N may also be turned on its axis and secured at any desired angle in relation to the tool-bar Q, thus enabling the tool to cut vgage a keyway cut in the rod I.

in any position. I provide also for raising and lowering the tool-bar Q, independent of the machine-slide to which it is attached, by making the arm H adjustable on the rod I, as in Figs. l and 2, and providing it with a gib and set-screw, Z, the former arranged to en- In Fig. 3 it is shown as xed to the rod. The slots W NV,

which are cut in the bar at right angles to' each other, arc-also elongated vertically, to allow of the vertical movement ofthe toolbar Q'without disturbing the reciprocating slide F. The tool-bar Q is during its adjustment temporarily supported by means of a set-screw, U, which passes through one ofthe fixing-straps T T, which form parts of the machine-slide head, and to which the tool-bar is ordinarily affixed, the end of the said setscrew engaging a groove, V, in the bar. This groove is made a little shorter than the slots W, so as to prevent the slide F and arm II from being damaged by the weight of the toolbar while it is being adjusted and fixed by the main gripping adjusting-screws of the straps T T. The tool-bar Q may be raised or lowered by means of a sling-chain arranged to hook into a ring, Q', inthe top of said bar. In lieu of an adjustable arm, H, several arms may be ixed to the rod I at intervals, and each be arranged to engage the slide F, desired, so as to adjust the bar to different heights without the use of the long slots V W', hereinbefore described. By cutting the slot W (in which the arm H plays) quite through the bar from front to back, the whole attachment may be reversed, so that the tool may work either in front or behind the bar.

Fig. 8 shows an arrangement of my invention designed for planing-machines in which the work remains fixed and the tools move over it, the tools being carried on the saddle of such a machine, which saddle is actuated by the main driving-screw of the machine or other similar ordinary means. In this construction the tools are reversed by means of tappet-rods O O, the projecting gibs on which engage the rocking tool-holders, and at the termination of each stroke the ends of the tappet-rods strike one or the other of the adj ustable stops B', mounted on the machine-bed. It will be seen that in these figures I have shown the perfect feasibility of employing and operating several double-cutting tools arranged in the same cutting plane, and in different cutting planes.

Figs. 9 and l() illustrate, in elevation and plan, the adaptation of my improved doublecutting tool to machines which have not the usual tool-relieving mechanism, and in which it is not convenient to actuate the tool-reversing mechanism through the medium of the machine-saddle, as above described. In this case I transmit the motion from an existing machine feeding-spindle, A, (or other equivalent para) to the tool-holder either through bevelwheels shown as driven by the right-hand rotary rock-spindle marked A in Figs. 9 and IOO IIO

l0, or by means of a lever and tappets shown as operated by the lefthand vertically-reciprocating feed-spindle marked A in the same figures. By this means an endless cord, A', 5 like the ordinary feedingfcord on some planing-machines, is given areciprocating movement. pets A A, suitably attached to a rod connecting the ends of the said cord, and these 1o tappets actuate an adjustable lever, B, and two quadrants, B,. which impart motion, through the lever or diskC', to the operating-k rod I, and through it, as before described, to the tool-holder. Fig. l1 shows details of this I5 mechanism.

In Fig. 12, instead of the quadrants B and disk C above referred to, is employed an arm,

B, directly connecting the tappet-lever B" with the actuating-rod I. 2o llhe modilications illustrated in Figs. 8 to l2, inclusive, are not herein claimed, and may form subject-matter for a separate application.

I claim as my inventionl. The combination of a double-cutting tool, 2 5 a rocking too1-holder, and a tool-holder socket, the socket being adjustable in a vertical plane on a horizontal axis, and the tool-holder and tool rocking in the socket on an axis at right angles to the axis of the socket, whereby the tool may be set to cut the work at any angle.
