ROBERT F. Bownns, 13, is secured in said openin Be it known that I,

a citizen of the United States, residing at washer 17, and screw 18. Fordyce, in the county of Dallas and State of is provided, through its w Arkansas, have invented certain new and useful Improvements in Ratchetrenches, of

which the following is a My invention has relation to improvements in wrenches, and 1s a ratchet wrench,

so constructed that it operate nuts or bit-shanks, or the like, of any size or shape, and turn them either backward or forward. This is acc reversible plunger and housing secured to the ratchetwheel, adapted to be filled by plugs having various shaped openings.

In the accompanying drawings Figure l,

is a perspective view of 2, is a top plan view of one of the caps. Fig. 3, is a longitudinal sectional view of my invention. Fig. 1, is a perspective view of the plunger and awl. Fig. 5, is a view of my wrench, part y in perspective and partly in section, the free end of the handle and the cap being a modification of the handle and cap shown 1n Figs. 1 an spective view of the housing, the larger art of the neck, the square that fits in the ratchetwheel, and the small part of the neck. Fig. 7, is a vertical sectional view of one of the additional plugs, adapted to fit a square nut.

Fig. 8, is a bottom plan adapted to fit a hexagon shaped nut. Flg. 9, is a vertical sectional view of a plug adapted to fit the shank of a boring bit.

Similar numerals refer to similar parts throughout the several views.

My invention is descr Referring more particularly to the drawings, the numeral 1, represents the head of my invention; 2, represents the handle and 3, the cap. The head is bifurcated, leaving two arms 4 and 5. These arms are provided with perforations 7 and 8, respectively, the lower perforation 7, being considerably larger than the upper perforation 8. Adapted to vided with two wings 37, imme fit in the space 9, between the said upper and site each other. The outer en having in ger, which passes through a pe I k 39 so: that d to turn the pawl lower arms, is a ratchct-wheel 10,

Thus it will be seen alternating the plugs I may screw or unscrew any size or shaped nut, and tool that may be adapted to in any plug adapted to fit my housing.

The handle 2, is provi with a longitudinal perforatio said longitudinal perforation, a turn therein, is a plunger has secured to its lower en means of corresponding recess responding projections 35. Said plunger and pawl fit loosely, but yet so snugly in said handle, that the two parts are held together by said recesses an tions. The purpose of having the it wears on be replaced by a new some little distance oss-rod, or stop-plate its outer end, is prodiately oppoof said plunrforation 38,

one. Said plunger has, from its outer end, a or 36. Said plunger, near d the crook end The housing 16, is integral with the lower face said plunger is a coiled spring 11, its lower end resting against said cross-rod, or stop plate, and its upper end against the inner face of the cap 3. When I desire to turn the ratchet-wheel to the right, I pull said plunger outwardly until from the slots I then turn the crook to the right, and slip the said wings down through the slots 40. To keep thesaid threaded cap from turning on the threaded end of the handle, I provide it with a lockspring 42, the free end of which is looked over a pin 43, secured in the handle.

he drawing, Fig. 5, shows a modification in which the cap 3, instead of being provided with slots 40, is provided with perforations 44, one immediately opposite the other, and the crook 39,-is turned down so sharply that it may enter either one of the perforations 44, and also enter corresponding holes 45, in the outer end of the handle 2. The coiledspring is for the purpose of keeping the pawl down between the teeth of the ratchet-wheel. Now, it will be seen that I may operate the ratchet-wheel and housing and any plugs that said housing may contain, either to the right or to the left, and the change of direction may be made by simply changing the crook either to the right or left.

Although I have specifically described the combination, construction and arrangement of the several parts of my inventionI do not confine myself particularly to such specific combination, construction and arrangement, claim the right to make such changes and modification therein as may clearly fall within the scope of my invention, and which may be resorted to without departing from t e spirit, or sacrificing any of my patentable rights therein.

Having described my invention, What I claim as new and desire to secure by Letters Patent, is

In a ratchet wrench, shown, a perforated handle, having on its free end a cap 3, and in the center-of said cap a perforation 38,- a pawl 33, working in the perforation of said handle, and a plunger 32, secured to said pawl, and working in said perforation, its free end extending up through the perforation in said cap, and formed into a crook, said crook, plunger and pawl adapted'to be turned to theright or left andsecured in such position, substantially as shown and described and for the purposes set forth.

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