TO ALL WHOM IT MAY CONCERN: l y

Be itknown that I, GEORGE B. PHILLIPS, of Poughkeepsie, in the county of Dutchess', and State of New York, have invented a certain new' and useiul Combined Drilling, Mortising, and Tenoning-Machine, applicable also to other purposes, of' which the following is-a full, clear, and exact description, reference being had to the accompanying drawing formingpart of this specification, andin whicl1- Figure l represents a side elevation of the machine with its parte as arranged for drilling.

Figure 2, a front elevation of the same. l y

Figure 3, a side view of the machine with its parts as arranged for mortisng, punching, or tenoning; and

Figures 4, 5, 6, and 7, views of details applicable as adjuncts for doin'g different descriptions of Work.

Like letters indicate like parts throughout the several iigures.

My invention relates to a machine .which is so constructed as that it combines, in the one, theuses of sevA eral machines, by merely certain changes in-or substitution of its details, and the nature of my invention consists in a detachable or hinged table-holder, connected to the standard or frame of themachine in such manner that it may-be readily detached or be turned aside, and so constructed as to receive and held in a central aperture, the shank of the table or other support adapted to the character of work to he operated on, as hereinafter described.A

Referring to the accompanying drawing, A represents a bench or table, on which the frame, B, of the machine vis bolted orv otherwise secured. C is the drill-stock or tool-holder, constructed sc as to be capable either ot' vertical play through, or xed rotation in; guides or bearingsa b, formedin projections or arms ofJtli'e frame. When the machine is designed to be used for drilling, the stock C, not being required to have longitu-g dinal travel downwards, the work moving up to the drill, it, the stock, is then locked or secured against such movement, and restricted to a rotary motion by an adjustable collar, D, provided with a set-screw or locking pin, c, which, gearing the collar with the stock, restrains the latter, by the intervention of the bearing b, from any downward action. i

l'Ihe table or faceplate, E, on which the work to beV drilled is held or secured, is constructed with a shank, d, that tsthrough a guide or holder, F, and is caused to carry the work up to the drill, e, (as it is rotated,) by means of a cam-shaped lever, AGr, working on a shaft, f, that is connected with a lower frame or bracket, H, the cam formation of said lever working against the under side or end ci' the shank d. A guide, L, made adjustable further in or out from the centre of the table E, answers to direct the work under the centre of the drill, or, it may be, in some cases, the mortising orpunching-tool. n'

To rotate the drill in the required direction, the upper end of the stock is fitted with aremovuble bush, V, gearing with the stock by means of aieather or otherwise, and having attached to it a bevel-wheel, z', that gears with a bevel-wheel, j, attached to a horizontal shaft, 7c, carrying at its opposite end a spur-wheel, l, which works into'a driving-pinion, m, fitted so as to freely rotate on a stud or shaft, n, secured to a slide or otherwise made adjustable up or down the frame of the machine, to facilitate different sizes of wheel and Vpinion being used, according to the speed or power required, which is further provided for by making the bush of the pinion m, in its it on the shaft n, or ily or hand-wheel I, withwhich it may connected, to correspond with the bore of the wheel Z, so that `without introducing fresh wheels, or adjusting the slide carrying the shaft u, the speed or power may be varied by slipping the pinion m on the shaft 7c, and the wheel l on the stud orshaft n, or, it may be, by omitting the attachment of the latter and working the shaftfk direct.

For punchingor mortising, the gear just described may-be dispensed with, and the collar I) is unlocked from the stock C, so asy to admit of its descent, when a spring, J, taking the place of the removable bush V, and acting against an arm, K, itted on to the stock, does not restrain it, the descent of the stock withits tool being elifected by a trcadle, L, connected by a rod, o, with the arm K, and the spring Joserving to throw it up again.

To drill the holes in tires, for the passage of the bolts that secure them to the fellocs of wheels, the table 7&,eos 51 E is removed from the holder F, and a tire-guide or supporter, M, (seo gs. 4 and 5,) inserted vby its shank p.. This supporter Mis provided with flanges, q, on either side, so that whether the tire he of the width between said anges, or less Width, it will always cross the centre of the shank p, as represented in fig. 5, and consequently come truly under the drill. v

'For punching or for gumrning saws, a dierholder, N; (see figs. 6 and 7,) may be secured on tothe face-plate E, anda suitable-shaped die, 1', inserted therein, and appropriately-shapedpunch.or.jtool, s, in the stock C.

To adapt the machine to certain other kinds of Work, it may be"` necessary not only to remove the 'table E, but also the holder F, which accordingly has given it asocketed construction, as at t, to fit. a tonguel pro jectingfrom the frame, whereby itmay be attached or detached at pleasure. Thus, for drilling andmortising work, suhstnntiallyas shown and described.

the hubs of wheels, said holder may, necessary, be removed, and (the lever G being taken away) the huh slipped 'on to the shaftfof the bracket H, and centred and held to itsl place by adjustable cones P, which'will serve to lit andcentre various bores of hubs larger than the shaft f. The same arrangement will,` likewise answer, on removing the table and its holder- F, to secure the wheels for the shaping of the tenons' on the ends of the spokes. p f

The bracket 'H should have a vertically-adjustable character given it, or the shaft f be adjustable to project at different heights therefrom, as, for instance, by allowing it to fit any one of a series of holes, u, or otherwise adjustable to suit different diameters or altitudes of work.

A machine, being capableV of so many variations as the one here described, vwill befound of great advantage in small Workshops or other places, as only small -and comparatively inexpensive adjuncts are necessary to convert it from one `kind of machine to another, land thus the purchasing of separate machines for'di'eient work is avoided.

What I claim as my invention, and desire to secure by Letters Patent, is-

The hinged or detachable holder F, so connected to the standard or frame B, that it may be removed or turned aside at pleasure, und constructed to receive the shank of the table, or other support adapted to the G. B. PHILLIPS.
