CARL F. ANDERSON, OF WEST NEW YORK, NEW JERSEY.

RATCHET WRENCH AND DRILL.

SPECIFICATION forming part of Letters Patent No. 659,564, dated 001701361 9, 1900.

Application filed January 17, 1900. Serial No. 1,817. \No model.)

To all whom it may concern.-

Be it known that I, CARL F. ANDERSON, a citizen of the United States, residing at West New York, in the county of Hudson and State of New Jersey, have invented a certain new and useful Ratchet Wrench and Drill, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to ratchet wrenches and drills; and the object in View is to provide a simple and effective device for imparting intermittent rotary motion to a drill or boring-bit, at the same time enabling the handle member of the device to engage bits or chucks of different sizes and shapes, the device being furtheradapted for use asaratchetwrench. The device also embodies ratchetcontrolled mechanism by means of which the boring-bit or drill-point may be actuated or turned in either direction.

Other objects and advantages of the invention will appear in the course of the ensuing description.

In the accompanying drawings, Figure 1 is a side elevation of a combined ratchet drill and wrench constructed in accordance with the present invention. Fig. 2 is a top plan view of the same. Fig. 3 is a bottom plan view thereof. Fig. 4 is a vertical longitudinal section through the same, showing a drillpoint and a drill-chuck applied to the rotatable head of the devicer Fig. 5 is a plan view of the stock of the implement with the rotatable head removed. Fig. 6 is a plan view of the thread-cutting die. perspective view of the chuck detached, omitting the sleeve. Fig. 8 is a detail perspective view of the chuck-sleeve. Fig. 9 is a detail cross-section through the rotatable, head of the implement, showing one of the jaws in elevation. Fig. 10 is abottom plan view of the rotatable head. Fig. 11 is a detail perspective view of one of the jaws carried by the rotatable head.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

In the drawings, .1 designates the stock of the implement, which is provided with a detachable handle 2, which is adjustable to different portions of the stock. For this pur- Fig. 7 is a detail pose the stock is provided with a longitudinally-extending reduced shank 3 and a laterally-extending shank 4. These shanks are preferably screw-threaded, and the handle 2 is provided with an interiorly-threaded socket by which it is adapted to fit over one or the other of the shanks 301* 4, as may be necessary, to adapt the device to different kinds of work and to enable the operator to hold the drill in difierent positions.

The stock 1 is recessed, as shown at 5, to allow the rotatable head 6 of the implement to be mounted therein. The head proper (indicated at 6) is seated in a circular rabbet 7 in the stock and is provided with a reduced portion 8, which fits and rotates within a cylindrical recess in the stock and is provided with peripheral ratchet-teeth 9, which are adapted to be engaged by a pair of sliding dogs 10, mounted in longitudinal recesses 11 in the stock and normally urged toward the ratchet-teeth 9 by means of expansion-springs 12, arranged behind the dogs. Each of the dogs is further provided with alaterally-extending operating and keeper pin 13, which works in a slot 14 in the stock, thus enabling the dog to be retracted or drawn out of engagement with the ratchet-teeth. Each slot is also provided at one end with an L-shaped extension 15, which provides a shoulder 16,

against which the pin 13 may rest for holding the dog out of engagement with the ratchet-teeth 9. The construction just described enables either one of the dogs to be held out of engagement, while the other dog engages the ratchet-teeth'Q and permits the rotatable head to be turned in one direction.

By reversing the positions of the dogs the rotatable head may be caused to turn in the.

opposite direction in a manner that will be readily understood.

The head 6 is provided with a shank 17,

which passes through the stock 1 and is provided with an annular groove 18, adapted to receive a pivoted locking-plate 19,-pivotedto an oblique shoulder 23 at the side of the stock, said shoulder being foi-uiedliiy a reinforcing-rib 24,formed on that side of the stock, as fully shown in Fig. 3. The locking-plate is further provided with an opening 25 to receive a fastening-screw 26, which fixes the locking-plate and maintains the enga ement between said plate and the shank of the rotatable head.

The extremity of the shank issquared, as shown at 27, to receive a thiinble 28, having a squared socket to fitnverthe part 27 and portion of the thimble 28.

longitudinally, with n which are oppositely 1ocated guideribs 33, having inwardly-di verging adjacent faces 34, thus forming a dovetailed recess or channel adapted to slid ing'ly receive and engage the dovetailed shanks 35 of a pair of sliding' and adjustable jaws 36, preferably provided with flat inner faces, whereby they are adapted to engage either the square shank of adrill-point or bor= ing-bit or a chuck, at the same time enabling said jaws to be used upon a nut in the capacity of a wrench. Passing longitudinally through the recess 32 and through the end walls of the head is a jaw-setting screw and chuckkey combined; This screw (indicated at 37) is provided at opposite sid es of its center with right and left hand threads, as shown, and passes through correspondinglythreaded openings 38 in the shanks of the jaws 36; so

" that by turning said screw the jaws may be moved toward or away from each other to clamp any object which is placed between them.

The guide-ribs 33 are centrally cut away, as shown at 39-, to receive between them the shank 40 of a chuck 41, and the shank 40 is provided in its inner end with a notch 42, adapted to receive the screw 37, which thus acts in the nature of a key and prevents the chuck from rotating independently of the ro-' tatable head, thus securing an interlocked engagement between the check and head, forcing said parts to rotate together; The chuck 41 may otherwise be of the ordinary construction, involving the jaws 4-3 and jawoper'ating sleeve 44. In order to prevent displacer'nent of the chuck, the retaining-snows 45 are provided, said screws passing through the rotatable head at opposite points and ohte'ring threaded holes in the shank of the chuck. From the foregoing description it ing the jaws 36 and a key for holding the chuck against rotary movement-with relation to the rotatable head. a

The outer portion of the stock 1 is provided with a longitudinal recess 46, in which is arranged a ihreadcuttiug die 47 in the form V of a disk having thread-cutting openings 48 of different sizes. This disk is centrally journaled by means of a removable pivot-screw 4!]; Which passes through a central opening 50 in the thread-cutter and through corresponding openings in the stock. The stock is also provided at itsend with oppositelyl ocated recesses 51, and any one of the openings 48 may be brought into line with the recesses 51 when it is desired to use the threadcutting part of the implement The thread"- cutter may be locked in any of its operative positions by means of a set-screw52, passing through the stock 1 and engaging against the adjacent surface ofthe thread cutting disk in a manner that will be readily understoodl From the foregoing description it will be seen that I have provided a combined ratchet drill and wrench which is adapted to have associated therewith drill points and chucks of discreet sizes and shapes and in which the chuck or drill-point engaging jaws may be utilized as wrench-jaws for grasping and op-- erating upon nuts, bolt-heads, one. It will also be seen that the rotatable head may be operated in either direction by manipulating the dogs which are carried by the stock an which operate in connection with said head.

I do not desire to be limited to the precise details of construction hereinabove set forth, as it will be apparent that many changes may be made in the form, proportion, and minor details of construction without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, iB
