STEPHEN McoLELLAN, on NEW YORK, N. Y., A ssIe'NoR OF ONE-HALF To DENNIS NUNAN, oF SAME PLACE.

UNIVERSAL BRACE AND DRILL.

SiEdIFiGATION forming part of Letters Patent No. 661,418, dated November 6, 1966.

Application filed February 24, 1900. Aerial No. 6.385. (No modeld To all wit/mt it flea/y concern.-

Be it known that l, STEPHEN MOCLELLAN, a 1

citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Universal Braces and Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains toi make and use the same.

My invention relates to improvements in hand-drills and bit-braces combined; and it consists in an improved form of brace and drill constructed as will be hereinafter fully described and claimed.

Reference is had to the accom panying draw ings, in which the same part-s are designated by the same letters of reference throughout the several views.

Figure 1 represents a side elevation of my improved brace and drill, the gearing being arranged to cause the drill-spindle to rotate at a higher speed than the operating-handle. Fig. 2 represents a similar view looking at the other side of the device. Fig. 3 represents a plan view of the same. Fig. 4 represents a central horizontalsection of the device, takentaken along the line 6 6 in Fig. 4;. Fig. 7 is" a similar view taken along the line 7 7 in Fig. 4. Fig. 8 isaperspective view of the casting for holding and "allowing the proper adjustments of the drill stock and spindle. Fig. 9 represents a detail sectional view of a modified device for locking the said frame and drill stock and spindle at the proper angle. Fig. 10 represents a detail view, partly in section, of a modified form of feeding device; and Fig. 11 is a view ofanother modification.

The several operating parts of the device are mounted in a frame A, consisting of the tubular portion A, to which is attached the forward forked portion having a long prong A and a shorter prong A To the opposite end of the tubular portion A is secured a frame or yoke A having a rectangular slot 0, and terminating in a screw A which latter passes through a slotb in the breast-piece B and is secured therein by means of a fixed head a and a nut A, as shown in Fig. 4. The long prong A is perforated at its end to form a bearing for the journal C of the frame 0,

which journal is secured in the said hearing by the screw 0 or in any othersuitable manner which will allow the said journal to turn in the said bearing.

The body G of the casting O is perforated, as at C to receive the stock D, which carries the drill-spindle E. A keyway c is formed in the perforation C and a corresponding keyway d is formed in the stock D. A key D is secured in the keyway o, as by a lug cl, projecting into a recess in the body 0 and the said key enters the keyway d in the stock D to prevent the latter from turning in the body C while allowing it to slide freely'therethrough. From the side of the body 0 cpposite to the journal 0 projects a sleeve 0 in line with the axis of the said journal, and the said sleeve is interiorly screw-threaded to receive a pin F, which is adapted to pass through the said sleeve and impinge against the stock D, which is indented, as at d at the proper places to receive it.

The stock D has near its forward end a frame or yoke D, which extends around the bevelpinion E, secured to the drillspindle E. This drill-spindle E has hearings in the stock on each side of the said bevel-pinion E, as at d and d and carries at its forward end the chuck E*, which may be of any suitable construction.

H designates a bevel gear-wheel having two sets of teeth, the set H being of the same size as the pinion E and the set H being considerably larger. Each set is adapted to mesh with the said pinion E at dilferent times.

The hub of the gearwheel H is fitted to rotate upon a sleeve K, to the outer end of which is rigidly secured a head K, which extends a short distance within the hub of the gearwheel H, the opening in which is enlarged, as at 7t, to receive it. The inner end of the head K is provided with notches k to receive the pawl I, which is arranged to slide in a sleeve L, secured to the gear-wheel H, and is provided with a spring 2", arranged to press the said pawl into the said notches 70. One side of the pawl is beveled, as at t', (see Fig. 5,) and when in the position shown it will be seen that the head K may be rotated one way without turning the gear-wheel H; but if rotated in the opposite direction the gear-wheel will be turned With it. The outer end of the pawl I is provided with a milled head 1 having a pin i which projects into slots L cut in the outer end of the sleeve L. Bylifting the pawl (by means of the milled head 1 until the pin 2' is clear of the slots L the said pawl may be turned in the sleeve to allow the ratchet to operate in eitherdirection. This is accomplished by turning the pawl one-half way around. By turning it one-quarter way around from the position shown the head K and hub of the wheel H may be locked, so as to turn together in either direction.

.The sleeve K is retained in the hub of the wheel H by means of a nut upon its inner end, and this sleeve K is arranged to rotate upon the sleeve 0 forming a part of the frame 0.

The head K is provided with a transverse opening near its outer ends through which the handle-bar M is adapted to pass, and the said head has an enlarged threaded opening 70 at its outer end to receive a nut N, which may be screwed down firmly upon the handle-bar M to retain the latter in position.

The handle M is slotted, as at m, through which slot passes the portion f of the pin F, this pin having a collar f below the handle anda thumb-piece F, having a hubf, which extends into the nut N nearly to the handlebar M.

By inspection of Fig. at it will be seen that when the handle-bar M is in the head K the pin F, although free to rotate, cannot be moved either inor out of the head K. When the parts are assembled, the pin F enters the sleeve C of the frame 0, and the sleeve K slips on the outside of the sleeve C. As the pin is screwed into the latter sleeve the sleeve K, and with it the gear-wheel H, is pushed toward the body portion 0 of the frame C, through which the drill-stock D passes, until the point of the pin F rests in one of the notches d in the said drill-stock. The several parts are so proportioned that when the point of the pin F rests in one of the notches in the stock D one of the sets of teeth on the gear-wheel II will be in engagement with the pinion E on the drill-spindle, and rotation of the handle-bar M will, through the medium of the head K and the gear-wheel H, rotate the said drill-spindle.

When it is desired to change the speed of the drill-spindle with relation to the gearwheel H, the pin F is unscrewed for a short distance, releasing the drill-stock, and by reason of the collar f impinging against the handle-bar M, moving the gear-wheel H away' from the pinion E on the drill-spindle, when the teeth on the gear-wheel are clear of the teeth on the pinion the stock D may be moved either forward or backward to bring the pinion E in position to engage with either set of teeth on the gear-wheel, the movement of the said stock being limited in one direction by the shoulder d and in the other direction by the stop-screw 01 so that the pinion will be stopped in the proper position to mesh with one or the other of the sets of teeth on the gear-wheel H. When the desired adjust ment has been made, the pin F is screwed in, bringing the gear-wheel H in engagement with the pinion and finally entering one of the notches d on the drill-stock to lock the latter firmly in position.

The frame 0 is provided with a mutilated wheel 0 the rim of which is somewhat thicker than the arms 0 and which wheel passes through an opening in the end of the shorter prong A of the frame A. The rim O is also perforated, as at 0 to receive a pin 19, attached to a pivoted catch P and arranged to enter through a hole in the side of the prong A into the perforations in the rim C A spring 19 is arranged to hold said catch in position to keep the pin p in the said perforations. By pressing upon the end P of the catch P the pin 19 my be lifted clear of the perforations in the rim O and the casting 0, together with the drill stock and spindle, may be turned to set the said drill-spindle at any desired angle within the scope of the mutilated wheel C such as the position shown by dotted lines in Fig. 2.

Within the tubular portion A of the frame A is housed a screw Q, extending at its forward end through the base of the forked portion of the frame A and having rigidly secured to its forward end a worm-wheel Q or bevel gear Q situated between the two prongs A and A The rear end of this screw Q passes into the yoke A and has rigidly fixed thereto a milled wheel Q by means of which the screw Q may be turned by hand. This screw Q passes through a sleeve R, arranged to slide in the tubular portion A and having hooks r projecting from its surface in opposite directions and extending through slots (1' in opposite sides of the said tubular portion A. In boring into hard substances when desirable achain 00 may be placed around the object to be operated upon and hooked on the hooks r, as shown in Fig. l. The drill may be then fed forward by turning the screw Q by means of the milled wheel Q or the worm-wheel Q or beveled gear Q In order to turn the latter, I provide a handle S, journaled in journal-blocks T and T and having a worm S or beveled gear in position to engage the teeth on the worm-wheel Q or beveled gear Q The journal-block T is pivoted at the base of the shorter arm A as at i, and the journal-block T' is pivoted in a slot at in the longer arm A and held in position ICC by 2b thu mlrserew I. 3y loosening: this screw 15' the jonrnnl-hlock 'l" is allowed to slide in the slot (1, and the handle :3 may he moved to the position shown in dotted lines in Fig. 3, at, which time the worm S or beveled gear will be out. of engagement with the worm-wheel Q, or beveled gem Q, and the screw Q may he turned by lnnnl by means of the milled wheel 4 Q when it is desired to run the hooks inn-k to begin another hole, as the screw can be turned lnsierhy ilie milled wheel Q lhan by die worm or beveled gearing aforesaid. It will be ohvions that, should in be desirableto do so,

either il' niillod wheel or the worm or beveled gearing may be dispensed wilh, leaving only one means for turning the fee lserew. The lnindle serves ZLlHOdS a means for holding the tool when in use, and should the Worm or beveled gem-lug he dispensed Wli h the said handle may be fastened to the frame A in any suitalile mnnner. l also provide a flied-screw U, which extends some distance in to the steel; l) and only be used when the stock is at; an zingle with the (frame A and n'nuitnhle abutment for the head u to hear against is available. The drill SlIOCli and spindle being nmde hollow, the feed-screw U may he made considernhly hmgor than those now in genernl use.
