c. P. BYRNE WRENCH Filed June l5. 1922 Patented Nov. 13, 19,23.
l UNITED 'STATES PATENT OFFICE.
Application filed .Tune 15, 1922. Serial No. 568,481.
To all whom t may concern:
Be it known that I, CHESTER P. BYRNE, a citizen of the United States residirg at Marysville, in the county of Yuba and tate of California, have. invented certain new and useful Improvements in a Wrench, of which the followlng is a specification, reference being had therein to the accompanying drawhis invention relates broadly to an improved wrench, and has more specific reference to a tool of this class which is especially designed for removing and applying nuts, bolts, cap-screws, and the like, the same embodying a socket in which a plurality of the nuts are to be forced as they are removed,
toether with a unique means for automati-` ca Ty ejecting the nuts from the socket.
he principal object of the invention is to generally improve upon tools of this class by providing one of extreme simplicity and durability which embodies the aforesaid socket in ,which the ejector is slidable, together with separate rotar means mounted on the shank of the brace or retracting and holding the ejector temporarily inA such'a state so that it will not interfere with the sliding of the nuts into the socket as they are successively or simultaneously removed.
More specifically, it is another object of the invention t0 devise a Wrench of the construction enumerated wherein the aforesaid rotary means embodies a sleeve having an especlally desi ed cam for acting on the spring-actuate ejector for retractin the latter When the sleeve is rotated relatlve to the shank on' which it is mounted.
Other objects and advantages of the invention will be apparent durmg the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:
Figure 1 is a side elevation of a wrench constructed in accordance with this invention;
Fig. 2 is an enlarged view of the shank, with the details shown partly in section and elevation to disclose' the construction and arrangement more clearly; f
Fig. 3 is a view similar to Fig. 2 showing the spring-actuated ejector in its normal position;
. tion Fig. 4 is a horizontal section taken on the l1ne 4-4 of Fig. 2;
Fig. 5 is a detail elevation, partly in sect of the improved retractor for the ejec- Fig. 6 is a cro-section taken on'the line 6 6 of Fig. 2; and
Fig. is a similar section taken on the line 7 7 of Fig. 4. f
In carrying out the invention, I prefer to employ a conventional type of brace 1 including a comparatively long shank 2, on the outer end of which a socket member 3 is fixed. In practice, the socket may be attached to the shank by means of brazing, shrinking or otherwise whichever method proves the most practical. According to the particular use to which the tool is to be put, the interior of the socket may be properly designed. In the showing, the socket is provided with a plurality of flat-faced walls for cooperation with hexagonal nuts and bolt heads. Referring again to the shank 2, it will be seen that this is formed with a socket 4 which extends inward and terminates adj acent the juncture of the shank with the U- shaped portion of the brake. At the terminal of the socket 4, the shank is equipped in one sidewith an elongated slot 5 forming a keyway. Slidable in the socket 4 is a relatively small rod 6 which may be conveniently referred as an ejector. As clearly shown in the drawings a small hexagonal plate 7 is secured to'- the outer end of the ejector rod in any suitable fashion and this plate is slidable in the socket 3 and is designed to engage the nuts N for ejecting them from the socket. The opposite end of the rod 6 is threaded as at 8 and this has detachable connection with a small block or theflike 9 which constitutes a key and is slidable in the aforesaid keyway. It is to be noted that this key projects beyond the.surface of the shank for a purpose to be hereinafter described. It may be conveniently stated here that in order to permit the ejector to function automatically, a coil spring 10 is used and this spring surrounds the ejector rod between the outer end of the shank and the aforesaid plate 7.
As before intimated, unique means is employed for the purpose of retracting the ejector and temporarily holding it in such position so that the ejector and plate which this sleeve is cut to EEB..
it carries will be positioned as clearly illustrated in Figs. 2 and 4. In this position, these parts will not interfere with the entrance of the nuts into the socket. Although this means could'be of some other construe tion, it has broadly been termed rotary means and it is to be rotated with respect thereto. rlhe means preferably comprises a sleeve 11 which surrounds the intermediate portion of the shank adjacent the aforesaidkeyway. As seen more clearly in Fig. 5, the inner end o rovide a helical cam 12. lt is'to be noted t at one end of this' cam is flattened as indicated at 13 to provide a seat with which the key 9 is designed tocoact when the ejector is in retracted position. At its opposite end, the sleeve 11 is formed with 'diametrically opposite small screwthreaded sockets 14 which receive the small screws 15 passing through the hand-grip 16 which surrounds the retractor sleeve. n practice, the surface of thehand-gripiwill be knurled as shown to provide a convenient hand-grip. Furthermore, a stop collar 17 will be arranged on the shank and this serves to prevent sliding movement of the parts 11 and 16 in an outward direction on the latter.
The operation of the tool is as follows: Before engaging the socket member with a nut or bolt to be removed or applied as the case may be, the hand-grip 16 is grasped by the left-hand while the brace 1 is gripped with the other hand. The brace then rotated toward theright while the hand-grip is held stationary. ln so doing, the helical cam 12 acts on the key 9 to move it over the cam surface to engage it with the aforesaid flat portion or Sleeve 13. Hence, it is obvious that the ejector rod 6 is slid inwardly in the socket 4 against the action of the spring 10 and the plate 7 takes the position shown in Fig. 2. When the parts are in this position, the ejector will not interfere with the entrance of the nuts N in the socket. The socket 3 will then serve to accommodate a plurality of nuts. When it is desired to force the nuts out of the socket, the rotary retracting means and brace are,a rotated relative to one another until the key 9 is disengaged from the Hat portion V13 of the cam. The spring 10'then acts to simultaneously return the ejector to normal position and to force the nuts out of the socket. It is to be noted that the parts 1 and 16 may be rotated in directions opposite to that first described or the brace can be held while the hand-grip 16 is grasped and rotated to the right to disengage the key from the seat 13 of the cam, thus obviatingthe necessity of the key following the cam surface from one end to the other to permit ejection of the nut. i
By carefully consideringthe description in connection with the drawings, persons f that ing a keyway` remesa familiar with devices of this class will doubtless be able to obtain a clear understanding of the invention.-` Therefore, a more lengthy and detailed description is deemed unnecessary.
Since probably the best results may be obtained with the construction and arrangement herein. shown and described, this is taken as the preferred embodiment of the invention. However, it is to be understood minor changes coming within the scope of the invention as claimed may be resorted to if desired.
