C. H. MYERS.

RATGHET WRENCH AND DRILL.

No. 446,073. Patented Feb. 10,1891.

UNITED STATES PATENT OFFICE.

CHARLES H. MYERS, OF PHELPS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE KEYSTONE MANUFACTURING COMPANY, OF BUFFALO, NEW YORK.

R ATCHET WRENCH AND DRILL.

SPECIFICATION forming part of Letters Patent No..44=6,073, dated February 10, 1891.

Application filed June 23, 1890.

To all whom it may concern: A

Be it known that 1, CHARLES H. MYEEs, a citizen of the United States, residing at Phelps, in the county of Ontario and State of New York,haveinventedcertain new and usef ulImprovements in a Combined Ratchet rench and Drill; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

My invention relates to combination-tools, and has forits object certain improvements in construction, which will be hereinafter described, and particularly pointed out in the claims In the accompanying drawings, which form part of this specification, Figure 1 represents a side elevation of my invention; Fig. 2, a vertical transverse section through the head of the wrench; Fig. 3, a side view of the stock or drill-holder detached; Fig. 4, an edge view of the same, and Fig. 5 a vertical longitudinal section of the wrench in a plane at right angles to Fig. 2.

Reference being had to the drawings and the letters thereon, A indicates a wrench provided with a bar B, upon which the jaws C C are supported, and are moved laterally thereon by a screw D engaging wit-h both jaws. The bar B is provided with an upward extension (L, which extends through the front end or head of the handle b of the wrench, and has secured to its upper end a ratchetwvheel c, with which a spring-actuated and reversible dog D engages, all of which features of construction of the wrench are fully set forth in my patent, No. 288,098. bearing date of November 6, 1883, and need not therefore be herein further elucidated.

Throughthe extension a is an aperture 6, into which the shankf of the stock or drillholder is inserted.

The stock or drill-holder E is provided with a head g,in which is a socket h to receive the head of the drill i, and is flattened or formed rectangular from the head 9 to the cylindrical portion of the shank to provide surface for the jaws O C to engage. At the junction of the flattened portion Z and the cylindrical portion are shoulders m an, over which the Serial No. 356,489. (No model.)

upper ends of the jaws C C close when in the wrench and in conjunction with the shoulder n, which engages with the lower side of the bar B and the shoulders 0 o, with which the jaws engage and secure the drill-holder against longitudinal movement in the wrench. The flattened portion of the drill-holder is also provided with arecess p to accommodate the milled disk g on the screw D. The shank of the drill-holder is screw-threaded at r from the upper surface of the ratchet-wheel 0 (when in position in the wrench) to its end, and with said screw-threaded portion engages a nut G, which, with the screw-thread 1*, forms a feed for the drill by which it is gradually fed forward and withdrawn. The upper end of the nut G is provided with a centeringpoint 8, a

By the construction and arrangement shown a very cheap, simple, and effective improvement is produced, which is capable of being used as a ratchet-drill when combined, or asa wrench when the drill-holder is removed.

Having thus fully described my invention, what I claim is 1. A wrench provided with laterally movable jaws, an aperture in the head of the wrench, and a ratchet, in combination with a drill-holder engaged by the jaws of the wrench and having a feed mechanism on one end, substantially as described.

2. A wrench provided with laterally-movable jaws, an aperture in the head of the wrench, and a ratchet, in combination with a drill-holder in the head of the wrench and having a flattened portion with which the
