DWIGHT S. GOODWIN, 0F WATER/BURY. CONNECTICUT, ASSIGNOR T0 OSCAR- S. FITZSIMONS, OF WATERBUBY, CONNECTICUT.

SET-SCREVI OR THE LIKE.

Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, DWIGHT S. GoonwrN, a citizen of the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Set- Screws or. the like, of which the following is a specification.

The object of my invention is to produce a device of the character described having features of novelty and advantage which will be hereinafter set forth.

Referring to the drawings Figure 1 is a plan view of the set screw. Fig. 2 is a central vertical section thereof. Fig. 3 is an end view of the o erative art of the wrench. Fig. 4 is a s1de view t ereof. Fig. 5 is an end view of the set screw showing in section the operative part of the wrench in position therein.

The set screw formin the subject matter of this invention is of t e type socketed: in its outer end to receive a wrench, the socket and wrench being fitted to form a driving connection so that the set screw can be operated by the wrench. I am aware that set screws and wrenches of this general type have been made heretofore but no particular attention has been paid to the character of the engaging faces of the wrench and set screw, and no account has apparently been taken of the fact that the walls of the socket are so thin that the end of the set screw is liable to be spread under the action of the wrench tending to cause it to bind tightly in place. For instance in a case where the socket and wrench were of hexagonal cross section the tendency of the wrench is to spread the set screw causing it to bind and the harder the wrench is turned the greater this binding effect is. By my invention I have overcome this difficulty by so forming the engaging faces of the wrench and socket that when the wrench is turned there will be no tendency to expand the socket end of the set screw and the tendency will be to contract it.

Referring to the drawings wherein one embodiment of my invention is illustrated a end is solid. The side wall of the socket has several recesses 2, the outer walls-of which recesses are concentric and the end walls are oppositely inclined or converging as shown. The right hand end wall of each recess is acted upon by the operating means when the screw is driven toward the right, and the left hand end wall is acted upon when the screw is driven toward the left. In order to effectively overcome the tendency of the socketed outer end to expand, each of the said end walls must incline rearwardly inward with reference to the direc tion that it is pressed upon by the operating means, and furthermore, the said operating means must bear upon the inclined faces of certain end walls which thereby have a wedging effect tending to contract the socketed end of the screw. The planes of the end walls of each recess are such as to pass from each end wall inwardly to the oppo- Patented Get. 14, 19513.

site side of the axis from that on which the said end wall is located, whereby the said planes meet at a point within the radii which are centrally disposed with relation to the recesses.

The wrench c is fluted as at 10 to form. projecting ribs 11 of size and shape to fit the recesses in the wall of the socket. Preferably the wrench is slightly tapered to facilitate fitting it in place.

By my improvement, the coacting faces of the wrench and end walls of the recesses 2, are so inclined that the pressure of the wrench on the driven end walls has a tendency to contract the socket and thereby prevent any enlargement of the outer end of the screw. This enables me to make thinner socket walls than could otherwise be made and thus I can safely make larger sockets in proportion to the size of the screw. The screws, in use, may have their outer end completely sunk within threaded holes and may be repeatedly screwed in and out with all necessary force without impairing the outer end of the screws.

1 claim as my invention,

1. A. rotating member having asocketed outer end provided with several recesses each of which has a concentric outer wall and inwardly converging end walls, the latter being arranged in planes that cross each other-between each respective recess and the axis of the said member, whereby the said inwardly converging end walls have a a general cylindrical body and a socketed outer end provided with recesses in the Wall thereof, each of the said recesses having end walls inclined inwardly in planes passing between the said recess and the axis of the said screw, whereby the said inclined end walls have a tendency to contract the said socketed end when acted upon by suitable operating means.

DWIGHT S. GOODWIN.
