SPECIFICATION formingpart of Letters Patent No. 745,059, dated November 24, 1903.

Application filed March 27, 1903. Serial No. 149,814. (No model.)

To all whom it may concern.-

Be it known that I, JAMES HOLLEY, a citizen of the United States, and a resident of West Palmbeaoh, in the county of Dade and State of Florida, have invented a new and Improved Brace, of which the following is a full, clear, and exact description.

This invention relates to a brace provided with a plurality of tools permanently attached thereto,'said tools being mounted in a movable holder, so that any one of the tools may be moved into position for operation the same as a tool or bit applied to an ordinary brace.

The invention involves, in addition, various minor features of structure and arrangement, all of which will be fully described hereinafter.

This specification is an exact description of one example of myinv.ention,while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional View of the invention. Fig. 2 is an elevation looking in the direction of the arrow at in Fig. l and showing the head of the brace with the carrier and tools removed, and Fig. 3 is an elevation looking in the direction of the arrow 1) in Fig. 1 and showing the. inner end of the carrier.

indicates the shoulder or breast knob of the brace, 11 the crank, which is provided with a handle 12, as usual, and 14 indicates the head of the brace,which is carried rigidly at the side of the crank opposite the shoulder-knob 10. The head is formed with a flaring opening 15, from the outer or lower side of which extends a radial opening 16. In the opening 15 is mounted to rotate the carrier 17, which conforms to the shape of the opening and is provided with a number of grooves 18, disposed longitudinally of the carrier. These grooves are adapted to receive the shanks 19 of the various tools 20, said shanks having slots 19 therein, by which they are engaged with and thus mounted to swing on a pivot-ring 21. This ring is placed in a circular recess 22 in the inner end of the carrier, such recess being best shown in Fig. 3. The slots 19 enable the tools to be placed in and taken from the brace. The Walls of the cavity or opening 15 keep the tools 20 in folded position--that is to say, extending longitudinally of the axis of the turning movement of the carrier 17. When, however, one of the tools reaches a position opposite the radial slot 15, said tool may be swung outward into the position shown in the top of Fig. 1, and the tool lying in this slot will then be held rigidly. For preventing the tool from returning to its folded position I provide a catch 21, which is in the form of a lever fulcrumed at the point 22'" and having at one end a finger-piece 23. A spring 24 presses the upper end of the lever outward from the head 1d, thus throwing the bill 25 into a notch 26, formed in the shank of the tool. The inner walls of this notch are curved in the arc of the movement of the bill 25 of the catch 21, and said bill is correspondingly booked, and therefore when the catch is in active position the tool 20 cannot be moved down into folded position. By throwing the bill 25 out of said notch the tool is then free to move. The catch 21 is placed in a transversely-extending cavity 27, formed in the outer side of the head 14 of the tool.

The carrier 17 is mounted to turn around a shaft 28, one end of which is seated in the head 14:, said carrier bearing between this head and a collar 29 on the shaft 28. A guard 30 is arranged to cover the points of the tools 20, said guard turning on the shaft 28 and on an extension 31 of a brace-arm 32, said extension having a collar 33 thereon and the shaft 28 having a second collar 34L, between which collars the hub of the guard 30 bears. The guard is formed with a peripheral notch 35, which receives the arm 32 and prevents rotation of the guard. Said guard is, however, capable of being moved outward to permit the passage of the tools 20 past it, and a spring 36 is provided to hold the guard yieldingly in active position.

In the use of the invention the carrier 17 should be revolved around the spindle or shaft 28, so as to place the desired tool opposite the groove or slot 16. This tool should then be moved out into active position and too spirit and scope thereof.

Should it be desired to use a different sort of tool, the first-mentioned tool may be thrown down into folded position and the next desired tool moved outward. In order to thus adjust the device, it is necessary to shift theguard 30, and this is effected by manually moving said guard out from the tool. Tools of any sort may be fitted to the brace. It is especially adapted for boring instruments, although, of course, other tools may be employedsuch, for example, as the one indicated at the lower side of the carrier in Fig. 1.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A brace, comprising a cranked shank, a head rigidly mounted thereon and having a radial slot, a carrier arranged to turn with respect to the head, a plurality of tools mounted on the carrier and capable of being moved independently to lie outward of the head, a shaft engaged with the head and on which shaft the carrier is mounted to turn, means for holding the outer end of the shaft in place, said means comprising an arm at tached to the shaft, and a guard having a hub receiving the adjacent ends of the shaft and arm and movable axially thereon, for the purpose specified.

2.
