ROBERT A. OSBURN, OF BIRMING .i
'i ALABAMA.
i CONVERTIBLE SOCKET WRENCH.
Application filed July 13, 1921. Serial No. 484,310.
To all whom t may concern.'
Be it known that I, ROBERT A. OSBURN, a citizen 'if the United States of America, residing at Birmingham, in the county of Jefferson and State of Alabama, have ,invented certain new and useful Improvements in Convertible Socket Wrenches, of which the following is a specification.
My invention relates to av socket wrench which is convertible into all of the different wrench sizes and shapes needed for tightening or removing the various nuts and bolts used on an automobile or chinery.
In its essence my invention comprises a plurality of sleeve wrench sockets each having different sized openings and all adapted to be inter-connected by cranks having -differentsized lugs or tenons adapted to fit in either end of the socket sleeves.
By the arrangement described, the Wrench can be adapted to form a brace or .a variety of cranks of different sizes, lengths and shape so that the end sleeve socketcan be applied to the Work in places most difficult of access.
My invention is also adapted to the formation of a crank for automobile engines by designing an interchangeable wrench sleeve having one end adapted to couple to the other piece of macrank shaft of the engine.
My invention also comprises the novel features of construction and arrangements of parts, which in their preferred embodimentsonly are illustrated in the accompanying drawings, which form a part of this specification, and in which Fig. l is a perspective view of my convertible socket wrench, the dotted lines indicating a change in position of the leverage of the wrench.
Figs. 2 and 3 are detail views illustrating the cranks with single socket wrenches reversely applied thereto.l
Fig. 4 is a detail view of the special crank sleeve` shown partly in section to illustrate its attachment to the double lug on the crank.
Fig. 5 is a detail view of the intermediate socket wrench sleeve showing a grip bushing or sleeve sprung thereon in quarter section. Similar reference numerals refer to similar parts throughout the drawings.
My invention as illustrated comprises three sleeve socket wrenches 1, 2 and 3 which are parts to increase ofthe same general character,l and each of which is provided with wrench sockets at reach end, the Wrench socket at one end of each sleeve being larger than that of the other at such sleeve. As shown the sockets in the sleeve 1 are both larger than either socket in the sleeve 2, and 1n like manner the sockets in the sleeve 2 are both larger than the sockets in the sleeve 3. As shown each sleeve is enlarged about half yof its length. The large and small sockets in the sleeve l are respectively designated A and B and the large and small sockets of sleeve 2 are designated C and D, and the large and small sockets of the sleeve 3 are designated E and F, respectively. The sleeves are adapted to be connected together by cranks 4 and 5, which are substantially similar and are provided at each end with double lugs adapted to lit the socket at either end o-a sleeve. The crank 1 has at one end 4two lu A and B to lit the socket B. At its other end the crank 4 vhas lugs C and D respectively, to t the sockets C and sleeve 2. The, crank 5 has at one end lugs which are similar to the lugs C and D on crank 4, and thus are adapted to lit either desired socket of the sleeve 2. At its other end the crank 5` has two lugs E and F adapted respectively tolit the sockets E and F of the sleeve 3. Y
In addition to the sleeves described 'I may, if desired, provide the Wrench withanadditional sleeve 6 provided at one end with a socket A adapted to t the lug A and having its other end 7 provided with notches 8 or other equivalent means for engaging the crank shaft of the type of engine to be worked. If desired the sleeve 6 may be provided with a set screw 9 to hold it rigid on the crank 4. It will be obvious that the tool, as
adapted,
shown in Fig. l, may be changed by applying the socket A to the 'lug A. thereby exposing the socket B to receive the nut, or in like manner the sleeve 3 can be reversed as indicated in Fig. 3. Both of these changes leave the apparatus assembled as a brace.
If it is desired to work nuts of intermediate sizes between those for which the sleeves l. and 3 are suited, the crank 4 or 5, as desired, is selected and the` sleeve2 is mounted thereon to present either end socket to the work. By changing the position of the crank 5 to'that shown in dotted lines, Fig. I, I convert the tool, as shown, from a D of the -mediate portion so that ai '.dling* work in dicultplaces.
'6 may be applied to i advantage of my double working .with the larger `work the brace to a crank which is adapted for han- Ubviously the crank 4 may be used alone with the sleeve 1 or the crank 5 with the sleeve 3, and in like manner any one of the sleeves can be worked as a crank wrench. Where desired, the sleeve the brace or to the crank 4 and used to crank the car, or, if desired, the sleeve 2 may crank that is'in service when working sleeve 1 or 3 to aord a better handle or grip.` @ne lug is that when lug in one of the sleeve. sockets in diiicult places l can, by partly withdrawing the crank to disengage only the larger lug and then turning the crank back and reinserting l wrench like a ratchet wrench', the smaller lug forming a guide for this purpose. 'lihis ratchet action is of peculiar advantage in many places diiicult of access.
The tool when not in use can all be taken apart and assembled in a very compact space and obviously thel cranks and sleeves can be designed to suit any class of work for which the toolA is intended.
ln order to provide the brace and cranky wrench forms with a handle which will turn freely in the hand, l show the intermediate sleeve 2 somewhat reduced at its interspringbushing of grip sleeve 10 is adapted to be sprung over thel sleeve and to form a .rotatable grip th'ere-` on which will function with either crank or with the' two cranks whenthe'wrench is wrench'. 'lllhis rotatable grip may be applied in any desired' manner.v
. This Iinvention is not intended to be rereduced to form a pair tenons on stricted in scope to the specic embodiments shown, but contemplates such 'modifications as come within the spirit and: scope of the claims.
Having thus described my invention, .what l claim as new and desire tosecure by Letters Patent, is
1. ln a convertible socket wrench comprlsing a crank lhaving at each end a lug socket tenons, and sleeves ferent sized wrench sockets at their ends adapted to fit corresponding sized socket their respective lugs.
2. A Wrench comprisin three sleeves having wrench sockets at their ends, and a pair of cranks having lugs swbstanti'ally at right angles to with the sleeve sockets to form an assembled tool.
A convertible socket wrenchcomprising be left applied to eitherI t with the sockets it inthe socket,
'of sleeves'having,
brace -grip member,
oi die-rent sized formed with d'ifple it .their ends and adapted to interit Lacasse two cranks, feach crank having at a corresponding end a pair of diferent sized socket tenons', and each' crank having at its other end a lug formed vto provide a socket tenons which are of .dierent size on each' crank, and reversible sleeves havingat theirendssockets to t either of their respective pair of socket tenons.
