To wZZ whom it may concern.

Be it known that I, JOHN A. LIDBACK, a citizen of the United States, residing at Portland, in the county of Cumberland and. State of Maine, have invented certain new and useful singlemachine which shall be capable of use in shaping,boring, drilling, planing, screw and gear cutting, and many other kinds of work.

As metal working machines are now made and used in a machine shop, many of them My machine being adapted for many diiferent kinds of work is designed to be always in use on one kind or another.

The principal features of the machine are a shaper bar or sliding headstock having a spindle mounted therein, a supporting bar I for the tool stock having an offset for supporting the outer end of the tool arbor and a revolving table which has several faces for holding different kinds of work, and which also has lateral and vertical feed.

I illustrate my invention in the accompanying drawings, in which- D Figure 1 is a plan of my machine. Fig. 2 is a part side View and part central vertlcal section with certain parts omitted. Fig. 3 is a front view. Fig. 4 isa section on X X of Fig. 1 and Y Y of Fig. 2. Fig. 5 is a section on X X of Fig. 2. Fig. 6 is a detail of one of the clutches.

B is the bed piece or base of the machine, it being secured to the top of the stand A.

On the bed piece B is the sliding headstock C which performs the same functions as the shaper bar in a shaping machine when my machine is being used as a shaping machine and as a headstock when my machine'is used as a milling machine. The headstock is held in guides in such a manner as to be capable of sliding on the bed piece. It is held down by side plates b bolted to the top of the bed piece, (Fig. On the sides of the sliding headstock I have formed brackets or shelves 1) for convenience in holding tools. Two uprightbearingsi 't' are formed on the headstock and in the lower portion of these bearings is journaled the spindle E which is preferably made hollow. e e are the bushings in which the spindle E turns.

The spindle E is rotated by means of a gear G which is secured to it as here shown immediately in the rear of the rear bearing 71. The gear G has a rearward extending collar or hub within which fits loosely the enlarged end of the feed screw D. The screw is held in place in the hub by a packing ring d.

The feed screw D is operated by a revolving nut H which is journaled in a bearing J secured to the rear of the bed piece and extending from one side to the other, over the rear extension of the headstock 0. On the rear end of thenut H is the gear H by which it is rotated,-these two parts being preferably formed in one piece. The inner end of the nut extends through the bearing J and the nut is held in place by collar h.

Power is conveyed to the gears G and H for rotating the spindle and screw by means -of the main driving pulleys M which are se- Z is shown as an ordinary forked clutch, a

particular description of'which is not necessary. The clutch j is the same except that it extends through the box J as shown in Fig. 6. The clutches Z and j are operated by forked ICO in rear of the pinion k by means of a train I of gears t t5 and pinion t such as are cornmonly used on engine lathes. The gear 6 and pinion t are made in one piece and are mounted on the end of an arm 25 which is pivoted to the fixed shaft 1' on which the gear t is mounted. The gear 15 engages the pinion I0 and the pinion t engages the gear 1 t which in turn engages the gear II. When the slow feed is not required the arm i is swung back and the gear 15 disengaged from On the front end of the headthe pinion stock- I place a tool block F such as is commonly used in shaping machines and which needs no particular description.

F represents the vertical feed screw and f is the tool.

The tool block is supported from the end of a supporting bar I which is journaled in the upper part of the bearings t' This bar is capable of being rotated in its bearings in such a manner as to swing the tool block entirely away from the spindle against the end of which it rests when in its working position. The bearings i may be clamped on the bar I by suitable bolts so that the bar is held rigidly or loosely as required. The tool block is fastened to the front end of the headstock by means of bolts f (Fig. 11) the heads of which enter a dove-tailed slotf, the outer edge being secured to the lugs f This groove is concentric with the center of rotation of the bar I so that if the bolts f are loosened and the bar turned the bolts will leave the groove and the tool stock will be released from the sliding headstock G.

On the same end of the bar I as the tool stock is the offset or arm 2" having a pin or pivot i used to support the outer end of the tool arbor 2', when turned down into the position shown in dotted lines in Fig. 2. 2 represents the milling tool.

In the front part of the machine I provide a revolving table 0 preferably made square and hollow, the different sides of which are adapted for holding dilferent kinds of work.

As herein shown I make two adjacent sides with the ordinary dove-tail grooves running at right angles to each other. On the third side which is the lower side shown in the drawings is a turret P mounted on guides 19 19 is a bracket for supporting the turret to give the latter sufficient travel away from the headstock. The table 0 is pivoted to the apron Q'which has a cylindrical projection or hub in front which enters the inner end of the table (see Fig.8) and on which itis adapted to rotate. The table Ois secured to the apron Q by means of bolts 0' the inner ends of which are turned at right angles and fit into an annular groove 0 formed around the outside of the hub. (See Fig. 12.)

The apron Q is supported in horizontal guide q in the cross slide R in such a manner that it has a horizontal motion with relation to said cross slide which is itself supported in vertical guides q on the front of the stand.

I provide a lateral feed for the apron and table by means of the feed screw r which extends through the apron and is journaled in the ends of the cross slide. On each end of the feed screw is a normally loose gear 1' which is capable of being connected or disconnected from the screw by means of clutches T The cross slide R is raised and lowered by means of a feed screw 0 stepped in the base of the machine. On the vertical feed screw 1' is a miter gear r which engages two miter gears a, one on each side, each being fixed to the inner end of ashaft r. The outer end of each of the shafts Wis journaled in the lower portion of the cross slide. On the outerends of the shaft 0" are normally loose gears T which are connected with the shaft by means of clutches 1'. Intermediate gears r r connect the gears r with the gears 4'. Hubs r are provided on the gears r, r by which the screws r and 7 may be turned by a wrench and the table fed by hand. The automatic feed of the two feed screws r and r is provided for by a connection with the drawing mechanism at the rear end of the machine. A horizontal shaft S isjournaled in bearings S S on the rear of the cross slide R. On its outer end is a gearS which engages with the intermediate gear 0' (Fig. On its inner end is a miter gear S which engages with a miter gear S connected with a vertical shaft S by means of a spline working in a groove S so that the gear has a vertical movement on the vertical shaft S, (Fig. 9.) A guide S extends from the bearings S over the gear S and holds the latter in contact with the gear S On the upperend of the vertical shaft S is a miter gear at which engages with a like gear on the end of a horizontal shaft-N journaled in bearings 01 and n on the side of the machine. On the rear end of the shaft N is a set of cone pulleys n which may be connected by a belt witlra set of cone pulleys m,on the independent shaft m. On this shaft in is a gear i which engages the pinion 7.; on the main driving shaft. It will thus be seen that the gear 11 aciingth rough the shafts and gears and pulleys last described drives the feed screw 7' by which the apron is fedon the cross slide and operates also the screw 0' which feeds the cross slides vertically. Either feedscrewor bothmay be discontinued disconnecting the clutches Hand r The feed of the sliding headstock C is reversed as in ordinary shaping machines.

On the top of the bed piece B is a guide 17* .arm are made adjustable as to position so that the headstock may have 'a long or a short motion.

The cross bar V furnishes a support for the rearends ofthe shafts m and Z.

Having thus described the construction of my machine, its mode of operation will be readily understood. When used as a shaper thetool stock F is in the position shown in Fig. 2, the. bar (Fig. 1) and its connecting gears are swung back and disconnected from the main shaft, the clutch Z is disconnected, the clutch j isconnected with pinion 7c, and the clutches r and r? are disconnected or connectedaccording to whether a side feed or a vertical feed is desired on the table. feeding nut H takes its motion from thepin ion being reversed by the shipper in the ordinary manner.

' the. bar I is turned over after loosening the bolts f (Fig. .11) bringing the offset t' down audit is then drawn out sufficiently far to allowthe tool arbor Z to be inserted. One end of the tool arbor is inserted in the conical end of the hollow spindle E and the other is supported by the pivot The tool arbor is rotated by the pinion Z which turns the gear G on the rear end of the spindle E. For drilling, a drill chuck is inserted in the tapering'hole in the end of the spindle, the tool arbor being removed.

Inusing the machine as a turret lathe, the tableis revolved so as tov bring the turret on top... A suitable chuck is secured to the end of thespindle and operated by the same feed as is usedfor the. shaper. For screw cutting a chuck isfitted in the end of the spindle, and the bar on which thescrewis to be cut is inserted into the hollowspindle projecting out over the .table. ,A suitable .cutting tool is secured to the table and the spindle and rod are turned by the turning of the spindle as described and fed by the slow motion imparted to the gear I-l through the train of gears 25 and t andtthearm i being thrown over to bring the gear 25 into engagement with the pinion is? (Fig. 1'). The outer end of the rod may be supported by. the pivot 71 if desired. The clutch j is thrown overand the pinion k is, disconnected. The screw being cut may be out off orone section may be cut and the bar being pulled outanother section cut and so on.

Thereare many other uses to which the machine can beepnt which will readily occur-to a For milling and boring mechanic. in operating it. It is obvious that the tool stock F may beset at any angle and fastened in position by the boltsf.

The revolving table may be set at any angle and-theshaping tool or the milling tool may be used. to cut inclined surfaces.
