INVENTOR. ROBERT L. GO0LE)1$ R.
A TTORNEKS United States Patent O 3,224,302 SOCKET WRENCH WITH A NUT EJECTOR Robert L. Cooley, Sr., 7660 Tori-em St., La Mesa, Calif. Filed Oct. 19, 1962, Ser. No. 231,745 2 Claims. (Cl. 81-1241) The present invention relates to a nut-ejector type socket wrench.
The wrench of the present invention includes an elongated sleeve having a socket at one end for receiving a nut which is to be turned. The sleeve is provided with an elongated, longitudinally disposed and constant diameter cylindrical bore, which is axially aligned with the socket and extends to the socket. The sleeve also includes a second elongated, constant diameter cylindrical bore, which is axially aligned with the first mentioned bore, and is of larger diameter than the first mentioned bore. The bores being so aligned and of different diameters, form a should-er at the junction of the bores. The end of the larger diameter bore, opposite the junction, terminates in a cylindrically shaped inwardly extending shoulder.
An elongated, cylindrically shaped, nut-ejector rod is disposed within the sleeve. This rod is of constant diameter throughout the major portion of both bores, and the diameter is substantially the same as the diameter of the smaller bore. This rod is provided with a shoulder within the larger diameter bore, which shoulder is arranged to abut the aforementioned inwardly extending shoulder of the sleeve. The rod is also provided with a section which extends outwardly of the larger diameter bore and beyond the sleeve. This rod is also provided with a longitudinal and cylindrical bore at that end thereof which is adjacent the socket for receiving the end of a screw of the bolt.
A coil spring is interposed between the shoulders within the second mentioned bore, and surrounds the nutejector rod. This spring is under compression and normally holds the rod in a position in which the end thereof is removed from the socket. The section of the rod which extends outwardly can be moved inwardly for engaging and ejecting a nut within the socket.
Other features and the advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of the invention is illustrated.
In the drawing:
FIG. 1 is a side view of the wrench;
FIG. 2 is a side view of the wrench, the sleeve and part of the rod being shown in section, the section being taken along line 22 of FIG. 1, said view being on a larger scale than that of FIG. 1, and
FIG. 3 is an end view looking in the direction of arrow 3 of FIG. 2.
Referring more in detail to the drawing, the wrench is shown at 20, and includes threemajor parts; namely, the sleeve 22, the ejector rod 24 and the coil spring 26.
The sleeve 22 is elongated and is recessed as at 28, to provide a socket 30 for receiving a nut (not shown). The sleeve is provided with two axially aligned, cylindrical bores 32 and 34, which extend longitudinally of the elongated sleeve. One end 36 of the bore 32 terminates at the socket 30. The bore 34 is of larger diameter than the bore 32, and a junction of these bores provides a cylindrical shoulder 38. The end 40 of the bore 34, opposite the shoulder or junction 38, is spun inwardly so as to provide a cylindrical shoulder 42.
The rod 24 is cylindrical in shape and complements the bore 32. The ejector end 44 thereof is longitudinally recessed as at 46, for receiving the screw on which the nut is threaded or is to be threaded. The opposite end of the rod 24 is provided with a fixed collar 48, which provides a shoulder 50. This shoulder 50 confronts the 3,224,302 Patented Dec. 21, 1965 shoulder 38. The end 52 of the rod extends outwardly beyond the end 40 of the sleeve 22. The coil spring 26 surrounds that portion of the rod 24 which is disposed Within the bore 34. One end of the spring 26 abuts the shoulder 38 on the sleeve, and the other end of the spring abuts the shoulder 50 on the collar 48. This spring is under compression and normally urges the rod 22 to the right, as viewed in the drawing. The collar 48 provides a second shoulder 54, which is adapted to abut the shoulder 42 on the sleeve, to limit the extent of movement of the rod to the right.
The rod 24, including the collar 48 and the extension 52, are formed of one piece of material and all parts thereof are circular in shape in lateral cross sections. Preferably, that portion of the sleeve 22, which surrounds the bore 34, is of larger outside diameter than that portion which surrounds the bore 32.
As previously stated, the spring 26 is under compression, whereby the end 44 of the rod is at the extreme right end of the socket 30, or may be to the right of the extreme end of the socket 30, so that the socket 30 can receive a nut. If the nut is on a screw or bolt and the bolt extends outwardly of the nut, such extended portion of the screw will be received by the recess 46 in the left end of the rod 24. Preferably, the portion 56 of the sleeve is knurled. As the nut is removed from the screw, the rod 24 is moved to the left by pressing inwardly on the extension 52, and in so doing, the nut is ejected from the socket 30.
From the foregoing, it is readily apparent that there has been provided a simple nut-ejector type socket wrench, which can be manufactured at a relatively low cost. Only three major parts are necessary: namely, the sleeve, the rod and the spring. The invention is particularly useful for small-scale nuts. The rod is formed of one piece, which can be readily manufactured by a screw machine. The sleeve is formed as an integral structure, and requires only two bores in addition to the socket 30. In assembling, it is necessary only to insert the rod in posi tion and then by a simple spinning operation, form the shoulder 42 for retaining the rod within the sleeve.
While the form of embodiment herein shown and described, constitutes preferred form, it is to be understood that other forms may be adopted falling within the scope of the claims that follow.
