Description

Aug. 1l, 1959 B. FEDESON DISC SOCKET WRENCH Filed Aug. 28, 1957 INV ENTOR.
27a/Wim Unite Staes Patent Thisrinvention relates to hand held tools, and moreV particularly to a disc socketl wrench.
The. discY socket wrench of the invention may be advantageously employed in certain situations where theI use of more conventional types of wrenches would be impractical, or impossible. A specific situation would relate to the application or removal of a nut from a stud, wherein the free end of the stud isrelatively long, therebyk making use of a conventional socketwrench impractical or impossible. A further feature of the. disc socket wrench of the invention allows use of the disc socket part of the wrench alone for easy turning-,of a nut, under4certain conditions. Anotherl feature relates to @holding arrangement of the disc socket whereby the disc socket may be easily maintained in engagement with anutduringthe turning thereof.
The main object of this invention is to provide a disc socket wrench which` may b e Vadvantageously employed in certain situations where the use.of more conventional types of wrenches would be impractical or impossible.
Another object of this invention is to provide a disc socket wrench wherein the disc socket alone may be used for easy turning of a nut under certain conditions.
Still another object of this invention is to provide a disc socket wrench having holding means whereby the disc socket may be easily maintained in engagement with a nut during the turning thereof.
These and further objects and features of the invention will become more apparent from the following description and accompanying drawing wherein:
Fig. 1 is a perspective view of a disc socket wrench embodying the principles of the invention;
Fig. 2 is a bottom plan view of the disc socket of the Wrench shown in Fig. l;
Fig. 3 is a sectional view as seen from line 3--3 in Fig. 2;
Fig. 4 is the same as Fig. 3 but illustrating the application of the disc socket to a nut threaded upon a stud;
Fig. 5 is a bottom plan view partially broken away in section and illustrating a modified form of the invention;
Fig. 6 is a sectional view as seen alo-ng line 6-6 of Fig. 5; and
Fig. 7 is a view showing a modified form of knurl used on the disc socket of Fig. 5.
Referring now to the drawing, the wrench of the invention includes a disc socket member 11 and Spanner wrench handle 12. 'Ihe socket member, which may be formed of metal, is disc-like in form and has a nut-engageable socket recess 13 entering from one face and terminating short of the opposite face so as to provide an inwardly directed ange 14 surrounding an axially arranged bore 16 which opens onto the face 17 of the socket member and which is of larger diameter than a threaded member receiving a nut engageable by the socket member. The ange 14 serves as a holding means whereby the socket member may be maintained against the top of a nut 18, or equivalent. The face of the socket member on the side of the socket recess 13, has a taper 19 to provide clearance when the socket member 11 engages a nut. A plurality of holes 21 are arranged about the bore 16 parallel with the axis of the tocket member, and extend from the tapered surface 19 through the opposite face of the socket member. The holes are arranged in pairs each of the holes of a pair being in diametrical opposition. The periphery of the socket member 11 has serrations 20 or knurls to afford iirm gripping of, the socket member when the latter is used for manually rotating a nut. the socket member is substantially greater than the diameter of the socket recess, thereby affording leverage for.y manually rotating the socket member when -it is [placed in engagement with a nut.
A'Ihespanner wrench handle 12 has a bifurcated end ligarranged to provide clearance about a stud when the handle is used upon theA socket membery 11. Extending from the bifurcated end of the handle412 are protrusions, orA pin members2l2. adapted for engaging` oppositely disposed holes 21 ofthe socket member 11.Y
As seen in Fig. 4, the socket member 11 may beV placed upon the nut18 mounted upon a stud 23 the free endy of which extends a substantial distance beyondthe top of the .nut 1 8. Such a use of thewrenchy of the invention would not,y be possiblewith conventional socket wrenchesv dueto theV length ofithe stud 23. Insuch position of the socketsmemberl 11, the nut 1 8 may be rotated by,
willhold the socketjmember in` positionrVupon the nuty so that operative engagement therewith will not be disrupted.
From the foregoing it will be seen that a disc socket wrench according to the invention may be used either for manually turning a nut upon a threaded member, or for using a wrench handle therewith if necessary to overcome rotational resistance of the nut. It will be further seen that the socket member may be used where the use of conventional-type socket wrenches would be impractical, such as when the nut is mounted upon a long stud, or equivalent. In addition, it will be seen that the holding means i.e., flange 14, will maintain the socket member in engagement with the nut during operation thereupon, a convenience which is not always afforded by wrenches of the prior art.
Referring to Figs. 5 to 7, a modified form of wrench is shown wherein a socket member 24, the body of which is preferably formed of a plastic material such as cellulose acetate butyrate, has a metallic socket insert 26 axially arranged as shown. The body of the socket member 24 has an axial bore 27 about which is arranged a llange 28 adapted to overlap the linner diameter of the socket insert 26, to act as a holding means in the manner of ange 14 in the previously described embodiment.
The socket insert has a straight knurl 26a arranged about its outer periphery, and has a circumferential rabbet 29 at one end thereof. A plurality of through holes 31 are `arranged in the socket member for engagement by the pin members 122 of the wrench handle 12 if the latter is to be used with the socket member 24. The outer periphery of the socket member 24 is knurled at '2.5 to afford a better gripping surface when the socket member is placed upon a nut for manual rotation.
The 'body of the socket member 24, being plastic, will be molded about the metallic socket insert 26, the latter being held in position between the flange 28 and the plastic material which enters the circumferential rabbet 29. The knurled surface of the metallic insert will lock It is to be noted, that the diameterof the insert within the socket member. Instead of straight knurls on the outer surface of the metallic socket insert 26, diamond shaped protrusions 32 may Ibe used for locking the insert within a socket member as illustrated in Fig. 7. In such an arrangement, it would not be necessary to provide a circumferential rabbet such as rabbet 29, since the diamond shaped protrusions will prevent axial or rotational movement of the insert relative to the socket member 24.
The use of the rnodilied socket member 24 for operation upon a nut, is identical to that of the socket member 11, the main difference `being in the manner of fabrication, and the material fused.
From the foregoing it will be seen that the disc socket wrench of the invention may be conveniently used where it would be impractical or impossible to use conventional type socket wrenches.
The foregoing description has been given in detail without thought of limitation since the inventive principles involved are capable of assuming other physical embodiments without departing from the spirit of the invention and the scope of the appended claims.
