VEHICLE-WRENCH.-

srEcIrrcA'rroN forming parz of Letters Patent No. 499,863, dated June 2o, 1893'.

Application illed January 23, 1393. Serial No. 459,413. (No model.)

To: all `whom, it may concern.-

Be it knowntliatwe, WILLIAM J. WALKER, of St. Louis, and ALEXANDER L. BEDFORD, of Savannah, Missouri, have invented certain new and useful Improvements in Vehicle- Wrenches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. Our invention has' relation to improvements 1n vehicle wrenches and consists in the novel arrangement and combination of parts more',

particularly described in the specification and set out in the claims;

In the drawings Figure 1 is a perspective ,view of our V complete invention. Fig. 2 isa.

plan view of they socket showing i-nv dotted lines the various sizes of nuts located therein;

and Fig. 3 is a vertical, crossfsectioiiv of the socket. .l In carrying out our invention the socket re ferred to is providedwith four lugs super posed thereon, the lugs being separated by spaces at the angles or corners of the socket. These spaces allow for the reception of a maximum sized nut, at the saine time reducing to a minimum the quantity of material compos-v ing the wrench, Ordinarily, in --case's where the band on the hub of ,a carriagecomes in close proximity to the nut secured to the axle,

- and which nut saidf'bandembraces, the rigid wrench as now used cannotbe inserted within the band to grasp the nut. Especially is this true inA cases where 'the nuts are small as in light buggies. In compact structures of-thisI sc rt our improved wrenchis particularly app'licable, as by our construction we' reduce .the circumferential size ofthe wrench .bydispensing with the metal which ordinarily-,enters intothe corners of such wrenches. The spaces at the corners ol.' thesocket allow the corners of the maximum size nuts to pass', andthus with a wrench composed Acf the minimum quantity of material the maximum numberof nuts can be operated one wrench doing' the work of two ordinary wrenches under old constructions.

Referring to the drawings, 1 lrepresents the handle of the wrench one end of 'which is providedwith three different sizedrigid vjaws 2 for receiving'nuts of various sizes, and formed cessity.

with said handle and adjacent to said flaws is 'a hammer 3to be employed in cases of ne- 4 represents the socket of thewrench the outer surface of which may be of any suit- 'PATENT OFFICE- sis able shape but preferablyl of the construction shown'in Fig. 1. fourlugs located or superposed upon the main portion 5 thereof.

6 represents the lugs referred-to which are separated at thecorners of the socket byspaces The socket is composed of 7 which' allow the corners of the largest sized nuts to pass as shown in dotted lines Fig. 2. .The main portion 5 of the socket has forfned on its inner walls four right angular grooves 8 midwaybetween the four corners 9, which groovesv are adapted to receive the four corners of the smallest nut v10 as shown in dotted lines Fig. 2. The four corners andthe walls at right anglesthereto are adapted to receive the next larger nut 11 as shown in dotted lilies in Fig. 2 ,Formedon the inner walls or s urfaces of each lug 6 are'right angular grooves 12 which receive the corners of the next larger nut 13 also shown Ain dottedlines in Fig-2; Said `lugs are provided with plane surfaces 14 which arel eight in numberA and which come .in contact with the sides of .the nut 15 shown indotted lines Fig. 2. A socket constructed as above .described is applied to nuts of various sizes from one side of the socket only, and

` when thus applied hexagonal as well'as square` nuts can be accommodated. r

0f course it will be understood that hexagonal nuts will not be accommodated snugly within the socket,gbut as.` the saine is constructed to receive nuts of various sizes the socket will grasp the nuts siivlciently for turn-- ing the same.l y

In constructing 'tlie socket a. continuous shoulder 16 is formed havingonjeach of the four sides thereof two surfaces 17 which ineline toward each other, and iiito'j-the right 'I angular shaped grooves 8, Aas shown in Figs. 1 and 3. These inclinations allow the nut 13 `to enter farther into the right angular shaped grooves 12 of the lugs 6 and thus enable said lugs to take betterhold of the nut.' Another object -of theinelined surfaces is to transfer a portion 'of .the strain taken by the, lugs to i the body portion of the socket.

'mainportion 5,V righty angular grooves 8 formed on thenner walls of lthe same, between the y 15 )corners 9, lugs 6 superposed on said portion 5 providing spaces 7, right angular grooves l2 formed on the said lugs, plane surfaces 14 also formed on said lugs, a continuous shoulder 16 having' inclined surfaces I7, and ahandle for zo i sa'id socket, substantially as'set forth.

In testi mon ynvhereof we ax oursiglmtures in the presenceof two witnesses.
