DANIEL E. NORRIS, OF ROBINSON, ILLINOIS, ASSIGNOR OF ONE-HALF TO FRANK H. NORRIS, OF ROBINSON, ILLINOIS.

WRENCH.

Application led March 31, 1919.

ATo all whom t may concern.'

Be it known that I, DANIEL E. NoRRIs, a citizen of the United States, residing at Robinson, in the county of Crawford and State of Illinois, have invented new and useful Improvements in Wrenches, of which the following is a specification.

More particularly the invention relates to what is ordinarily known asaratchet wrench and the object of the invention is to give to the parts, especially those parts which are subjected to severe strain, greater rigidity.

The invention is illustrated in the accompanying drawings as follows Figure l shows a plan view of the wrench partly in section on the line l-l in Fig. 2.

Fig. 2 a side elevation, partly in section, on the line 2-2 in Fig. l.

Fig. 3 a plan view from the opposite side of the wrench from that shown in Fig. 1.

Fig. 4 a view of the forked end of the handle before assembling showing the manner 0f assembling.

The wrench has a handle l. This is provided with the forked end, the forks 2 of which are formed integral with the han- Bearing openings 3 are formed in each fork 2. The wrench piece l has the ratchet teeth 5 on its periphery, these teeth being arranged intermediate the ends of the wrench piece and trunnions 7 extend toward the ends from the ratchet, these trunnions fitting the bearings 3. A wrench socket 6 is arranged in the wrench piece.

The wrench piece is placed between the forks as shown in Fig. 4 and the forks are then bent to the position shown in Figs. l,

2 and 3. They are secured together by a Specification of Letters Patent.

pin 9 which eXtends from one fork to the other, the distance piece 8 being also secured by the pin 9. A ratchet 10 is journaled on a distance collar 11 which is arranged on a Ipin 12 extending between the arms. This pin 12 supplements the pin 9 in securing the forks together. These pins are arranged as will be seen between the bearing openings 3 and the point 0f attachment with the handle. A spring 13 eXtends between the rear end of the pawl or ratchet 10 and the distance piece 8, the distance piece forming a base for the spring. V\7ith this structure there is great rigidity and in as much as the means of attaching each fork to the handle is similar there is no tendency-of one fork to give thus causbinding, on the trunnions.

What I claim as new is In a ratchet wrench, the combination of a handle having a forked end, the forks 0f which are integral with the handle and each fork having a bearing opening; a wrench piece having ratchet teeth formed on its periphery intermediate its ends and with. trunnions extending toward each end, said trunnions being journaled in the bearing openings in the forks, the trunnions being placed in the bearings by springing the forks distance pieces arranged between the forks;

pins extending through the distance pieces securing the forks together; a pawl pivotally mounted on one of the distance pieces; and a spring extending from the other distance piece to the pawl.

In testimony whereof I have hereunto set my hand.

DANIEL E. NORRIS.
