COMBINED SELF-FEEDING BE NCH-DRILL AND LATHE.

SPECIFICATION forming part of Letters Patent No. 559,003, dated April 28, 1896.

Application filed May 17, 1895. Serial No. 549,626. (No model.)

T0 aZZ whom it may concern:

Be it known that I, JAMES B. TAYLOR, a citizen of the United States, residing at Fairview, in the county of Sierra and Territory of New Mexico, have invented a new and useful Combined Self-Feeding Bench-Drill and Lathe,of which the followingis a specification. The object of my invention is to produce a neat, cheap, portable, and efficient drill for use by gunsmiths, watchmakers, &c., one which can be readily and firmly attached to a bench or table, and which will automatically feed the work to a drill, and which can also be quickly adapted for use as a lathe.

A further object of my invention is to reduce the friction to a minimum and prevent any cramping of the traveling upright which carries the work up to the drill.

Another object of my invention is to provide means wherebythe cylindrical guides, which guide the traveling upright, will bear evenly and thereby prevent any variation or jumping of the work while being carried onto the drill by the upright traveler.

Another object of my invention isito provide a self-feeding drill with a clamping device which will advance upon the drill in the same plane, and at the same time so arrange the parts that the drill and advancing clamping device will be free from obstruction, will be easy of access, and will have sufficient clearance for ordinary work.

My invention also comprises the various features of construction and combinations of parts hereinafter fully set forth and claimed.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation of my improved device. Fig. 2 is a sectional view on line 2 2, Fig. 1, looking toward the right. Fig. 3 is an enlarged fragmental view showing my improved chuck-holding vise. Fig. 4 is a view of one of the jaw-blocks removed from the upright.

I11 the drawings, A represents abed-plate, which is provided with two clamps B B, mounted at right angles to each other, so that one clamp will clamp upon the edge and the other clamp will clamp upon the end of the table or bench. By this arrangement the clamps hold the drill more rigidly in place than is possible when the clamps are arranged parallel with each other.

C 0 represent two uprights of the drillframe. These uprights are arranged at one end of the bed-plate A and project upward therefrom and serve as a support, in which is journaled one end of each of the rotating guide-shaftsD D, and also one end of the screw feed-shaft E. The other ends of such shafts are journaled in a single upright F, which is arranged at the other end of the bed plate.

Upon the guide-shaft E is secured a driving-pinion d. This pinion meshes with an upon the guide-shaft D. A drill-shaft G is journaled in the frame above the gear-wheel cl and is provided with a pinion g, which is arranged to mesh with the gear-wheel d. This shaft is providedwith a chuck G and with a band-wheel g, arranged upon the outside of the frame of the drill-frame.

,of a vise-screw J to grip the material to be drilled and to hold it rigidly in position in front of the drill G. The upper part of this upright I, which supports the vise, is provided with a rectangular opening K, within which two blocks 7c of hardened steel are arranged. The ends of these blocks are grooved and slide along rods K, which are inserted through the upright after the blocks are placed in position in the opening. Two vise-screws L L are screwed through the upright and attached, respectively,to the blocks is and 7c,so that such blocks may be forced together to grip a chuck or any object to be drilled and may be shifted from one side of the rectangular opening to the other, if desired. This allows the article which is gripped by the jaws to be shifted so that that part of the article into which it is intermediate gear-Wheel cl, which is secured desired todrill the hole may be brought directly in front of the drill. This also enables me to use my machine for drilling holes in the ends of shafts or rods, and such holes may be bored either centrally or eccentric to the center of such shaft, as desired. D is a crank by which the mechanism is operated.

The pinion cl is detachably secured to the shaft D by means of a set-screw 2, so that when it is desired to use the device as a lathe such pinion may be detached from the shaft D and by rotating the shaftE and by means of the crank e the upright I may be carried backward and forward to suit the work to be turned.

A center-chuck (not shown); is fixed between the jaws 7a 7a and a suitable lathe-chuck is fixed in the chuck G. Then the pinion g is freed from its engagement with the shaft G and a band (not shown) is passed over the pulley-wheel g, whereby the work is ro-- tated. ranged to support the cutting-tool. However, these are minor matters in which any one versedin the art is familiar and therefore it is not necessary that I- should makea detailed description of such matters herein.

By means of the crank e the screw-shaft E maybe rotated tocarry the support I nearer to or farther from the chuck G tosuit the article to be turned upon the lathe.

By arranging thetravelingupright I upon the guide-shafts D D and by causing such guide-sl'iafts to rotate as the upright travels therealong to carry the work against the drill practically all friction is avoided, and the guides constantly present a new face to receive the pressure which must be borne th ereby and prevent the traveling upright from cramping upon the two guides D and D, and y this means the device is adapted to be used 1 they are therebycauscd to wear evenly.

Any suitable support may be a-rfor an indefinite period without becoming worn to-such an extent as to impair'its effectiveness.

Now,'having described my invention, what I claim as new, and desire to secure by Letters A Patent, is- 1. The combination set forth of the guideshafts; the feed-shaft the upright arranged to be operated by the feed-shaft and to travel along the guide-shafts, and provided at its upper end with the rectangular opening; the jaw-blocks groovedat eachend and arranged in the opening in the upright; the rods inserted through openings provided in the up.- right, seated in the grooves in such blocks vise-screws, one screwed through each side of jsaid upright and secured to one of the jaw- ;blocks; the drill-chuck; means for rotating the chuck and meansfor operating the feedishaft. I

2. In a drilling-machine, the combination f the frame; the driving-shaft journaled in the frame and provided with the driving-pin- ,ion; the drill-shaft journaled in the frame land provided with the driven pinion; the intermediate gear-wheel meshing with the driving-pinion and with the driven pinion; two parallel guiding-shafts secured tovthe frame; screw-threaded.feed-shaft provided with a gear-wheel, and journaled in the frame pari allel with the guiding-shafts; a traveling caririer arranged to be carried back and forth Eupon the guiding-shafts by the action of the ifeed-shaft; and a pinion connected with the iintermediatc gear-wheel and meshing with 1e gear-wheel upon the feed-shaft.
