T0 all whom it may concern.-

Be it known that I, I-IoNEsTUs M. ALBEE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Vtoodworking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,referencebeinghad totheaccompanying drawings, and to letters and figures of reference marked thereon,which form a part of this specification.

r1"his invention relates to certain improvements in that class of machines for cutting or carving spiral grooves in the peripheral surfaces of wooden sticks, illustrated in my United States Patent No. 408,366.

For this present invention, subsequent to the filing of the application but before the issuing of this patent, l have received patents in foreign countries as follows: England, No. 13,864, dated August 17, 1891; Belgium, No. 96,103, dated August 31, 1891; France, No. 215,601, dated December 4, 1891; Germany, No, 62,889, dated June 14, 1892, and Canada, No. 41,789, dated February 2, 1893.

,i The objects of the present improvements are to facilitate the operation of cutting reverse spirals, to secure greater perfection in the work, to provide against vibration when turning spirals on sticksof comparatively large size and to secure other advantages and results, some of which will be set forth in connection with the description of the working parts. The invention consists in the improved wood working machine and in the combinations of parts thereof substantially as will be hereinafter set forth and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters and figures indicate corresponding parts in each of the several views, Figure 1 is a plan of the machine. Fig. 2 is an end view and Fig. 3 a rear view of certain reversing mechanisms, and Fig. 4, a detail showing more clearly the construction and arrangement of a certain carriage. Fig. 5 is a detail side view of a stick holder, rest or support.

In said drawings, a, Fig. 1, indicates a suitable fixture or support for a bracket, b, carrying pivotal bearings, c, for a vibrating arm d. Said arm consists of pivoted sections d', d2, d3, and, at the outer end of the section, d3, a vertically adjustable section, el, which last provides bearings for a rotary shaft, e. Said shaft carries a rotary carving or routing tool e. At the joints in the sectional arm, and on the rotary tool shaft, are pulleys f', f2, f3, and f4 and these are connected by belts, g', g2, g3, g4, with any suitable motor or source of power, so that rotary motion will be imparted to the shaft, c, and tool carried there, by, all as will be understood.

Below the plane of movement of the vibrating arm and its tool, on a suitable table or support, h, is arranged a lathe, between the centers, c' and j, of which, the wooden piece to be turned and ornamented with a spiral or other desirable ornamentation may be arranged, and back of said centers is a screw shaft, lc, which is geared to the shaft j', of the center j, by a train of gearing 7a2, k3, kt, clr, shown more clearlyin Fig. 2, by means of which the screw shaft and the center, j, and the wooden piece carried thereby, are caused to turn simultaneously at proportional rates of speed, the movement of the screw shaft governing the movement of the wooden piece worked upon, as will be understood.

On the screw shaft is arranged a carriage, lt', which slides longitudinally upon the plate, h', of the table, its movement being induced by the rotation of the screw shaft. To this carriage is attached the vibrating arm and rotary carving tool by means of a bar, la, the said tool being held thereby in a position to engage the turning stick or wooden piece. By turning the hand wheel, m, on the screw shaft, (power being applied to the rotary carving tool) the stick is caused to revolve slowly with the center, j, and the carriage, it', is forced to move longitudinally, carrying the carving tool on the jointed arm with it and, as a result, a-spiral groove` is cut in the stick. It frequently happens, however, in ornamunicatereverse movement 'to the `wheel 76.4

, extension7611.

mental wood work, that two sets of spirals are desired, pitched in opposite directions, the oppositely pitched grooves being in one and the same stick, giving a diaper effect to the ornamentation or the said oppositely pitched grooves being in separate pieces.

To secure a reversely pitched eut quickly and accurately, is one of the important features of the present improvement. To this end, I provide means for reversing the direction of pivotal' movement of the stick in its relation to the screw shaft. This is accomplished by means of a vibratory frame or plate 769, Figs. 2 and 3, pivoted or centered on the shaft, 76, and having, at suitable points thereon, gear wheels 763, 767, adapted to engage with the Wheel, 764,0f the train of gearing and be disengaged therefrom alternately, as will be understood. The wheel, 763, receives its powerdirectly from the gear wheels, 762, on theshaft, 76, while the wheel, 767, receivesl its power from thev said wheel, 762, mediately or through the intermediate gear wheel, 768, so that its movement will be in a reverse direc.- tion fronrthe .,wheel, 763, and will thus comand lthe wooden piece geared thereto. The adjustable frame or plate, 769, is held in either of thetwo positions of operation, by means of aset screw, 7610, which werks in a slotted ,t In connection with the lathe center'j, I have provided a gage disk, p, which .turns on the same pivotal shaft with said center and the gearorcog wheel 766 as shown onlyin Fig. l. The periphery of said disk is divided off by I equi-distant graduations, say six, eight or ten,

dividing the periphery into sixths, eighthsor tenths, or the said periphery, may be, and preferably is, divided cireumferentially as shown, one of the subdivisions having six graduations enabling the workman to readily make six cuts or grooves at proper distances apart on the stick, the second subdivision havingeight and the third ten graduations as willl be ,readily understood.

Adjacent to, the graduated or marked periphery of theV disk, @,is a fixed or stationary index, q. This is preferably secured upon the box or bearing r, for the shaft referred to` in Iconnectionwith the center j.

, By means of the gage arranged as described, the 'longitudinal' or spiral grooves-may be quickly and accurately spaced on the stick. In operating this device, the first groove may bestarted on the periphery, the index. coincidingrwith an initial graduation of eitherone ofthe series desired. As the stickrevolves and the spiral groove is being eut, the disk alsorevolves and when the next graduation lniark arrives at the` index, the tool may be lraised out of the first spiral groove and brought again to the end of the stick and a second groove started at a proper point regulatedby the index and this maybe continued until the stick has the requisite number of 'properly spacedgrooves.

lplate 3.

In the prior device, above referred to, it may be observed that a stick holder is provided, consisting of jaws adjustable in relation to one another by means of adjusting screws and movable with the carriage. Such a device is desirable more particularly and especiallyin connection with very small work of a certain class requiring bearing close to the routing tool. For larger work, I have provided a holder or rest s, shown more clearly in Fig. 5, consisting of a V-shaped head t, so that the round and either ,parallel sided or tapered stick will have two bearings in the holder at opposite sides of a longitudinal and vertical central plane through the stick. The said head has aleg, u., which is adj ustably secured to an adjustable stud, o, arranged on the bed or plate, 7a', ofthe table, being'V held thereon by vset screws, t" adapted to admit of a ready changeof position in accordance with the necessities of the work. Thus the V-shaped head maybe raised or lowered, adjusted longitudinallyv with respect` to the Q stick and changed in angle to correspond, for example,

with a taper inl a baluster. v z

To enable either large or small sticks to be l operated uponand to regulate .the depth of the groove` in the stick, without changing the gear wheels and centers of thelathe, yand to secure peculiar effects in carving in vaccordance with a desired pattern, I havemade the carving or routing toolvertically adjustable in `its bearings, the adjustment being controlled by a guide rod, w, and tracing tool,

w', adj ustably arranged on lsaid rod, and the latter being attached toa vertically sliding plate which controls the vertical movement o f the tool shaft, as described particularly, in

a cotemporaneous specification or in any other suitable manner. By raising or lower- `ing the pattern, 4, orby varying the upper bearing surface of said pattern, giving the same a waved surface for example, the-depth `of the spiral groove will be correspondingly varied. If the work to be operated upon be very large and beyond the limits of vertical adjustment of the tool shaft, then I may lower theytable, 71 in any suitableV manner, (the jmeans for doing so not being shown, the same being old,) to admit of the introduction of the said large work to theV centers. To do this and yet secure the proper connection and support of the vibrating arm with the carriage, 76, and bed plate 7L', I have made the connections vertically adj ustableas shown in the drawings, where h2, indicates an elevated track at the rear of the plate7t, on which the said carriage slides horizontally when forced by the screw shaft 76. y t

7612 indicates a vertically slotted arm of said carriage; 7620 a clam p adapted toreceive a bar or extension, 7613, of a plate, 7611, which controls the movement of the vibrating arm and `furnishes a bearing for the vertically sliding When vthe table, h, is to be lowered, the clamp, 762,0, is first loosened totadmit of the lowering of the table and lathe andl after- IIO ward the parts 7612 702 7513 are again brought into rigid connection by the nut 7050.
