Specification of Letters Patent.

Application filed June 16, 1913. Serial No. 773,972.

To (ZZZ 107mm it may concern:

Be it known that I, LEWIS R. VVr-rnnnnn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Machine-Tool, of which the following is a specification.

My invention relates to machine-tools wherein universal features are sought, and the objects of my improvement are to provide a mechanism of portable and convenient size upon which castings and bar stock can be turned, milled, drilled, threaded, knurled, faced, bored, etc., without recourse to the customary and various machine-tools known to the trade as lathes, milling machines, shapers, drill-presses, etc, at present requisite to mechanical operations. By rea son of the requirement of these various and expensive machines it is found inexpedient to equip the laboratory, garage, etc, for machine work, even when it would be most desirable that such work should not be performed elsewhere.

This invention primarily aims to provide the necessary elements of a tool for machine work in such novel form and correlation of parts as will readily adapt the tool to a great variety of work.

The invention aims to provide a lathe-bed of novel form having one section extended into an upright column, upon which is placed a headstock, which, while normally in alinement with a tailstock as in a lathe, may be adjusted vertically by a lead-screw or other means; and also to provide means whereby the spindle of said headstock may be swiveled in a vertical plane, and further, to make such adjustments without interference with the driving mechanism of said spindle, and in such manner and in such combination with the other component parts of the machine as to make the tool equally efficient upon the different classes of machine-work.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1. is a perspective of the entire machine, and Fig. 2. is a sectional view of the head or spindle section showing the swiveling member turned in a perpendicular direction, as well as the driving members of the spindle.

Like numbers refer to like parts through out the two views.

A bed casting (1) having planed ways on the upper surface serves as a support and guide for the carriage members (2 and 3) as well as for the tailstock (27). This carriage section is composed of the saddle casting (2) and the slotted table (8), the latter having a transverse motion in the saddle and the combined functions of holding either a tool-post and stationary tool or clamped work such as castings which may be bolted to its upper surface. A column section (4) is cast integrally with, or bolted rigidly to the bed (1) and serves as a support and guide to the headstock castings (5 and 6),

the latter carrying the live spindle (7). This spindle is driven from the rear by the cone pulley (8), the universal joint (9), the shaft (10) keyed to same by a feather key to allow a limited telescopic motion, the universal joint (11 Fig. 2) and the bevel gears (12 and 13 Fig. 2.) respectively.

Of the elements which make up the headstock, one, (5), is gibbed to the slide of the upright section of the bed, and may be raised or lowered upon said section 1) by the screw (14) the nut (15) and the handle (16) or by other suitable means. The other member (6) is machined to fit over the casting aforementioned in such a way as to allow itself to be adjusted to any angle in the vertical plane. Such angle is obtained accurately by the graduation marks inscribed upon the casting (5) as shown at 17, and such angle may be retained by the clamping screw 18. An out-board bearing arm 19, passed through a bearing in the casting 6 of the headstock may be clamped rigidly to same, and at a desired distance from same, by the clamping screw 20. A train of change-gears consisting of a pinion 21 on the spindle, an idler 22 on the stud 23 held in the slotted link 24, and a gear 25 on the horizontal lead-screw 26, have the function of driving the table or carriage in the required relation to the revolution of the spindle, when the head carrying said spindle is adjusted into alinement with the tailstock, all as customary in regular lathe practice. These parts are many of them of common and familiar construction, but their combination, arrangement and juxtaposition form a novel tool of wide scope in machine work, allowing operations, for which many different machines have formerly been necessary, to be done on one tool, acquiring thereby a machine of wide commercial value and great practical utility.

In the practical use of the machine for milling, work bolted to the T slots of the table 3 in the usual manner may be fed under a rotary cutter mounted upon an arbor (not shown) carried by the spindle. The outer end of this arbor may be supported if necessary by the arm 19. If such work be of a nature to require an end mill, the spindle maybe swiveled to a perpendicular posi tion as shown at Fig. 2 and the table and work fed underneath the end mill in the required directions. If the work should be a gear, it may be mountel on a circular table (not shown) and bolted to the regular table and indexed by: the usual worm gear mechanism, while theformed cutter mills the desired number of teeth in the periphery of the blank. In a similar manner, other forms of cutters such as slitting saws, emery wheels, etc, can be placed upon the arbor in any of its positions and the work fed to them."

In' the practical use of the machine for drilling, the head section is turned to a vertical position as shown at 2 and the work laid or clamped to the table underneath. The spindle is then fed'downward by means of the lever 28, thus giving the sensitive action necessary to light drilling. In this position a tool may be held in the stationary spindle to handily accomplish small key-seating jobs.

Copies of this patent may be obtained for In the practical use of the machine for lathe work, a chuck may be screwed upon the nose of the spindle and the work held therein, or the work may be held between centers, the head having been dropped to a level where it is in proper alinement with the tailstock. In either case. the work is then rotated by the spindle and acted upon by the stationary tool held on the table, thereby accomplishing any ofthe operations of turning, facing, threading etc.

lVhile the elements herein shown are well adapted to serve the purposes set forth, it is obvious that minor changes may be made in the proportions, shape, and arrangements of the several parts without departing from the spirit and scope of the invention as defined in the'appended claim.

Having fully described my invention, I claim,

In a machine-tool, the combination of a lathe-bed as described, a carriage, a tailstock, a vertically adjustable headstock composed of two main members, :the one swiveling upon the other, a graduated dial upon one of said headstockmembers, and a spindle driven from the rear by means of bevel gears, universal-joints and telescopic shaft, said driving members extending throughthe center of the upright section of the lathe-bed.

In testimony whereof I ailix my. signature in the presence of two witnesses.
