`The present invention relates to new and useful-improvements in'machines formaking dowels, -forming tenons on stock and for performing similar mill work, Aand the invention l-has foriits yprimary object to provide afmachine of this character of relatively small and compact form .adapted for mounting on awork'bench andfcaypable .of easily and quickly performing `its function. v

.'An important object of the present invention .Lis to provide Lmeans for interchangeably :mounting a tool bit holder and a facing cutter'in `the machine to adapt the machine for either cutting dowels of a predetermined diameter or for cutting tenons or'roundng either `one or both ends f .of stock of either round or square shape.

A further object of this invention is to provide a novel construction for mounting guides of various diametersv in the-machine for the dowels While -the same are being cut. .An additional object is .to provide an adjust'- :able front guide for the stock andzadapted to :aceeommodate stock of various sizes.

A .still "further object is to provide a device of "this character of simple Vfand,ipracticaliconstrucftion, which is eicient and reliable in operation, relatively inexpensive to manufacture and in- .stall inoperative position on-a work bench and which otherwise is well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like reference numerals refer to like parts throughout, and in Which- Figure 1 is a longitudinal sectional view showing the tool bit mounting in position for cutting dowels,

Figure 2 is a fragmentary longitudinal sectional view showing a facing cutter mounted in position in the machine, l

Figure 3 is atop plan View,

Figure 4 is a transverse sectional view taken substantially on a line 4-4 of vFigure 1,

Figure 5 is a fragmentary front elevational view of the front guide for square-shaped stock,

Figure 6 is a transverse sectional view taken substantially on a line 6--6 of Figure 2,

Figure '7 is a fragmentary front elevational view of the front guide provided for round stock, and

Figure 8 is a side elevational view of the diameter gauge for setting the tool bit.

Referring now to the 'drawings in detail, wherein,rfor the purpose of illustration, I have ldisclosedfa preferred embodiment of the invention, the numeral 5 'designates a base plate ceiving the tubular shank I0 'having an enlarged tool-supporting head kI-.I at its frontend. `The head 'I'l is `provided with "a plurality of`ra`dially `extending openings l2 in which tool bits I3 :are

fa'djustably vmounted and secured in radially ad- 'justedpositionby means `of set screws 114.

'The tool head Il is formedwith'atsocket I5 defined by a shoulder .l5 at its inner "endiand ared, as at I1, at the outer or front :endio'f the toolhead.v 'The bore ofthe shank "lpat: its juncition 'with the socket 15'is also' .'ared, as. indiwcatedat t8..

`A tubular adapter `i9 isv positioned inthe bore :of vthe shank. l0 `and has its front iendflared, :as .indicated `at'2li, corresponding to the "fiaredportion I8 of the tool head Il. The rear'end ofthe :adapter I9 isf'formed with `a flange 2l which abuts `the rearend ofthe shank l0.

A` pulleyl 22 .is positioned on the rear end 'ofthe shank yIl) behindthe bearing body 'L'the pulley Ybeing formed .withaiflange 23 bymeans of which the pulleytis'secured to the shank .im as weil iasto the adapter i9 by means of a set-screw 24.

The adapter I8 forms a rear guide for the dowel 25 cut by the tool bits I3, said guide having an internal diameter corresponding to the diameter of the dowels.

Extending transversely at the front of the base plate 5 are a pair of spaced, parallel guide rails 26 between which is slidably positioned a rib 21 formed on the bottom of a front guide designated generally at 28. The guide 28 is preferably constructed of a metal angle iron member 29 forming the bottom and'rear of theguide and in the angle of which is secured a wooden block 30.

The block 3l), as well as the rear wall of the angle iron member 29, is formed with aligned openings 3| which may be of square shape as shown in Figure 5 in the drawings to conformably receive square-shaped stock 32, or the openings may be round, as indicated at 33 in Figure 7 of the drawings, for receiving round stock as indicated at 34 in Figure 2.

The openings 3l and 33 are of graduated size for accommodating stock of various sizes and the several openings of the front guide 28 are secured in aligned positions with the tool head I I by slidably adjusting the guide on the track 26 and securing the guide in adjusted position by means of a set-screw 35.

The bearing body 7 is formed with an annular oil chamber 36 which surrounds the bushing 9 and is supplied by means of an oil cup 31.

A guard 38 is mounted for sliding movement on the bearing body 'I to cover both the cutting head |`I and the pulley 22, suitable openings (not shown) being formed in the guard to accommodate a drive belt for the pulley and the oil cup 31.

In the operation of the device, a diameter guage 38" is provided which is inserted in the rear end of the shank ID to position one of the stepped portions 38 of the guage at the inner ends of the bits I3, and the bits adjusted in accordance With v the diameter of the dowel to be cut. The gauge 38 is then removed and the adapter I9 of an internal diameter corresponding to the diameter of the dovvel to be cutis then inserted in the shank I and secured in position by the set-screw 24.

The front guide 28 is then adjusted on the rails 26 to bring one of the openings 3| into alignment with the tool head I I according to the size of the stock being used and the end of the stock slidably moved through the guide 28 into cutting engagement with the tool bits I3, whereupon the dowel 25 ywill be cut at the end of the stock.

When it is'desired to cut a tenon 39 with a facing cutter on round stock 34, for instance, the front gauge 40 having the round opening 33 is then placed in position on the rails 25, and the tool bits I3 removed from the cutter head I'I and a facing cutter 4I placed in position in the socket I and secured therein by set-screws 42. Round stock may be held by hand against turning in the frontfgauge 49.

In View of the foregoing description taken in conjunction with the accompanying drawingsyit is believed that a clear understanding of the construction, operation and advantages ofthe device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein de- What I claim is:

1. A wood-working device comprising a base having a journal member, a tool support including a tubular shank journaled in said member, means for securing a cutter in one end of the tool support, a drive member attached to the other end of the tool support, and a tubular guide secured in the shank and adapted for holding one end of the work, transverse guide rails on the base and a second guide having aligned gauge openings therein of diierent sizes for receiving the other end of work of diierent sizes, said second guide being slidably adjustable on said rails transversely of the axis of said tubular guide to position work of different sizes in axial alignment with said tubular guide.

2. A woodworking tool for turning down work of rectangular and round shape in cross section, respectively, comprising a base having a journal member thereon, a tool support including a tubu- Vlar shank journaled in said member, means for securing a cutter on one end of the tool support, a drive member on the other end of the tool support, a tubular guide secured in said shank for slidably holding one end of the work for feeding tosaid cutter, a second guide having an opening therein for holding the other end of the work as it is fed to the cutter, said second guide comprising an apertured angle member and a similarly apertured block secured to said angle member with the aperture in the block aligned with the aperture in said angle member.
