Specification of Letters Patent.

Patented Oct. 10, 1905.

Application led July 26,1904. Serial No. 218,286.

To /L/ 'IN1/mn, it may con/cern,.-

Bc it known that I, ADoLPH BAUsnR, a citizen of the United States, residing at Brooklyn, in the county of .Kings and State of New York, have invented new and useful Improvements in Combined Drilling-Machines, of which the following is a specification.

My invention relates to a combined drill and speed-lathe; and its object is to provide a device of this character which can be readily converted into either a lathe or drill and which is compact and durable in construction.

Another object is to provide the machine with a drill-spindle which can be adjusted to any desired angle to the horizontal and which can also be adjusted for use as the center or chuck of a lathe.

Another object is to employ power-transmitting devices which do not require readjustment when the position of the spindle is changed.

iVith the above and other objects in view the invention consists of a base or standard having a laterally-extending arm at its upper end on which is adjustably mounted a tailstock. Revolubly mounted at the upper end of the standard is an adjustable arm having pulleys journaled thereon and provided with brackets in which is revolubly mounted a spindle having a pulleyT secured to it. Powertransmitting mechanism is arranged upon the standard and fixed arm, and means are employed whereby power is transmitted from this mechanism to the pulleys on the adjustable arm.

The invention also consists of means for locking the adjustable arm in any position to which it may be moved. The invention also consists in the further novel construction and combination of parts hereinafter more fully described, and pointed out in the claim.

ln the accompanying drawings l have shown the preferred form of my invention.

ln said drawings, Figure 1 is a front elevation of the machine, showing` the parts in position for use as a drill and also showing in dotted lines the position of the adjustable arm when the machine is to be used as a lathe. Fig. 2 is a side elevation of the machine. Fig. 3 is a horizontal section through the upper portion of the standard and the adjoining' parts of the machine. Fig'. 4 is a perspective view of the cone-pulley adapted to transmit power to the mechanism of the machine. Fig. 5 is a similar view of a sleeve used in connection with the machine. Fig. 6 is an elevation of the guide-pin of the adjustable arm. Fig. 7 is a side elevation of one of the pulleys on the adjustable arm, and Fig. e is a similar View of the drive-gear of the mechanism.

Referring to the figures by numerals of reference, l is a standard, the base 2 of which is adapted to be fastened to the floor by means of bolts 3 or in any other suitable manner. The upper end of this standard l is reduced in thickness to form a head L1, the periphery of which is concentric with a stud 5, which extends rearwardly from the center of the head and has an enlarged portion 6 intermediate its ends. An arm 7 extends laterally from the head A and is provided with guidebeads 8, on which is slidably mounted a tailstock 9, in which is adjust-ably located a spindle 10. A securing device in the form of a jam-nut 11 is connected to the stock i) and extends through a slot 19J in arm 7. By means of this device the stock can be secured in any position to which it may be adjusted.

A slot 13 is formed within the head e and is concentric with the center thereof. This slot extends between one vertical and one horizontal radius of the head and has a guidey pin 14 slidably mounted therein, both ends of said pin being screw-threaded, as shown at 15. Pin 14 engages a disk 16, which is located in rear of and contacts with the head 4, the inner face of said disk being' provided with an annular bearing-'flange 1T, which contacts with the head 4. A jam-nut 18 is arranged on one end of the pin l-.t for the purpose of clamping the disk 16 in any position to which it may be adjusted. An arm 19 extends from the disk 16 and overlaps head a. This arm hasa rearwardly-extending bracket 20, on opposite sides of which are journaled pulleys 21 and 522. An arm 213 extends forward from the bracket Q0 and forms a bearing for a spindle Q4, having a pulley 25 adjustably feathered thereon. A guide-stri p Q6 is secured to the front face of arm 19, and adjustably-mounted thereon is a bracket 2T, in which the spindle 2st is journaled. A set-screw 2S is arranged in this bracket and is adapted to lock the bracketQY in adjusted positions on the guide-strip 26. Arranged loosely on the spindle QT, within the bracket Q7, is a sleeve 18, fixed against longitudinal movement relative to the spindle bymeans of collars 19 and provided with vertically-arranged rack-teeth 20', engaged by a toothed gear 21', rotatively journaled in the bracket and adapted for operation by a handle 09' these parts being all of the usual TOO IIO

or any approved construction and designed for feeding the spindle 24 in the ordinary manner to its work.

The slot 13 is solocated that when the guidepin 14 is at the lower .end thereof arm 19 is in a vertical position and when said pin is at the upper end of the slot arm 19 is in a hori- Zontal position and in alinement with the center of the fixed arm 7. A guide-strip 30 is arranged longitudinally upon the front of standard 1, and adjustably mounted thereon is a bracket 31, having an arm 32 extending therefrom, on which is secured a table 33, which is adapted to assume a position directly under the spindle 24 when said spindle is in an upright position.

Journaled upon the stud 5 is a sleeve 34, having a flange 35 at one end and a longitudinally-extending key 36. The sleeve 34 extends through a gear 37 and a pulley 38, and key 36 engages both of them, so as to cause them to rotate in unison with sleeve 34. A stud 39 extends rearwardly from arm 7 at a point adjacent head 4, and revolubly mounted thereon is a cone-pulley 40, having its hub 41 provided with a key 42. Arranged on this hub is a large gear 43,- which is engaged by the key so as to cause it to rotate with the cone-pulley. Gear 43 meshes with gear 37, and the cone-pulley is adapted to be rotated by a belt (not shown) operated from any suitable source of power. A belt (not shown) is also adapted to transmit power from pulley 38 to pulley 21, and another belt (not shown) is employed ,for transmitting power from pulley 22 to pulley 25. It will of course be understood that the two pulleys 21 and 22 are secured to the same shaft, and therefore rotate in unison.

Then it is desired to use this machine for drilling purposes, a suitable-drill is secured to the lower end of spindle 24 and the table 33 is adjusted to a desired height. Arm 19 is Jam-nut 18 is then turned so as to clamp the parts in their adjusted positions. y Motion is transmitted from gear 43 to gear 37 and from pulley 38 to 21 and 22 to 24. It will be nunderstood that spindle 24 can be adjusted vertically while it rotates by loosening the set-screw 29 and moving the bracket 27 upon its guide 26. Vhen it is desired to use the machine as a chuck, jam-nut 18 is loosened and arm 19 swung into a horizontal position, as shown by dotted lines in Fig. 1. When in this position, the guide-pin rests within the upper end of slot 13 and can be secured by the jam-nut 18. Spindle 24 alines with spindle 10, and the article to be worked can be very readily secured therebetween and rotated thereby. This machine is of durable and compact construction and answers every requirement of the two machines ordinarily used for the two operations of drilling and milling.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described the invention, what is claimed as new is In a machine of the character described, the combination with a table and a support; of an arm extending from the support, a tailstock mounted upon said arm, and an adjustable arm pivoted to the support and adapted to be secured in alinement with either the table or the first-mentioned arm', and a revoluble element upon the adjustable arm.

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

ADLPH BAUSER.
