1 claim. 1
Y This invention relates to wrenches adapted to be used in close quarters where it is diiiicultto turn a nut or bolt with a'conventional wrench, and in particular a wrench having sockets journaled in opposite ends of a bar with an endless chain mounted on the bar and trained over the sockets at the ends whereby a socket at one end of the bar may be positioned over a nut or bolt and rotated by a crank on the socket at the opposite end of the bar.
- The purpose of this invention is to provide means for turning a nut or bolt where it is difficult to place a conventional wrench over the nut or head of the bolt. V
Various types of extensions have been provided for wrenches, however, in numerous instances it is necessary to provide a special tool for turning a nut or bolt in a comparatively inaccessible DO- sition on a motor vehicle engine or other machine. With this'thought in mind this invention contemplates a wrench wherein a socket in one end that may be positioned over a nut or bolt head and that may bel rotated from the opposite end of the wrench by an endless chain incorporated in the Wrench. l
The object of this invention is, therefore,A to provide means for forming a, wrench whereby a socket journaled in one end of a handle and positioned with the axis thereof perpendicular to the handle may be rotated by an endless chain from the opposite end of the handle.
Another object of the invention is to provide means for rotating,r a socket in one end'of the handle of a wrench from the opposite end of the handle in which the socket may be held by a latch so that the device may be used as a conventional wrench,
A further object of the invention is to provide a wrench for turning nuts and bolts in close quarters in which the wrench is of a simple and economical construction.
With these and other objects and advantages in view the invention embodies an elongated bar having sockets extended therethrough and journaled in the ends, with an endless chain trained over said sockets and positioned to travel on the sides of the bar, and a crank having sockets therein to correspond with the sockets extended through the bar whereby the wrench may be actuated by the crank.
Other features and advantages of the invention will appear from the following description in connection with the drawing, wherein:
Figure 1 is a side elevational view illustrating the improved chain socket Wrench showing a 2 crank extended from one end of the wrench and with part of the crank broken away.
Figure 2 is an elevational view looking toward one edge of the wrench.
Figure 3 is a longitudinal section through the wrench taken on line 3-3 of Figure 2, with part of the wrench broken away.
Figure 4 is a longitudinal section through the Wrench taken on line 4 4 of Figure 1 and also with part of the handle of the wrench broken away.
Figure 5 is a cross section through the bar or handle of the wrench taken on line 5 5 of Figure 4, showing a latch for holding a spring biased pawl of the wrench with the ratchet disengaged from a socket at one end of the Wrench.
Figure 6 is a cross section through the handle of the wrench taken on line 6--6 of Figure 4 with the socket removed and showing the end of one of the spring biased pawls of the wrench.
Figure 7 is an elevational view showing a crank for operating the wrench, 'and with part of the crank broken away.
Referring now to the drawing wherein like reference characters denote corresponding parts theimproved T-spot wrench ofr this invention includes a bar It providing a handle, sprockets Ii and I2 journaled in the ends of the bar, a chain I 3 trained over the sprockets and positioned to slide over the edges of the bar, a square socket I4 extended through the sprocket II at one end of the bar, a hexagonal socket I5 eX- tended through the sprocket I2 at the opposite end of the bar, a spring biased pawl I6 for holding the sprocket II at one end of the handle, a spring biased pawl I'I for holding the sprocket I 2 at the opposite end of the wrench and a lever providing a crank I8 having a square opening I9 at one end for receiving the socket I4 and a hexagonally shaped opening 20 in the opposite end for receiving the socket I5.
The bar I0 forming a handle is provided with bifurcated ends providing flanges 2l and 22 at the end in which the socket I4 is positioned and anges 23 and 24 at the end in which the socket I5 is postiioned and, as illustrated in Figure 4 the sprocket II is journaled in annular recesses 25 and 26 in the flanges 2I and 22, respectively, and the sprocket I2 is journaled in similar annular recesses 2'I and 28 in the flanges 23 and 24, respectively.
The socket i4 extends through, and is secured in the sprocket I I, preferably by welding and the socket I5, which extends through the sprocket I2 is secured in the sprocket by similar means.
AIn the design shown the chain I3 is formed with links and lugs and the sprockets are provided with spaced sockets or pockets 2S and 30, respectively, which receive the lugs, however, it will be understood that a chain of any suitable type may be used and the sprockets may be provided to correspond with the chain.
As illustrated in Figures 3 and 4 the spring biased pawl I6 is provided with a stem 3k that is slidably r'iouhtedin an opening 32k i the b'ar l'0 and the spring biased pawl is resiliently urged to ward the sprocket by a spring 33, one end of which bears against a shoulder 34 in the bar and the other against a collar 35 on the spring bia'ed pawl. The end of the stem 3| of the spring biased paWl is provided with an arm 36y that positioned to extend over a liig or finger 3T in a opening or cutout 38 for retaining the spring biased pawl with the end thereof withdrawn from the SQCliet By this means the spring biased pani It may be withdrawn to release the sprocket j I when it i's desired te turn the socket Il with the `chain and when` it is desired to use the wrench as a conventinai secret the are; 361s turned where,- by it passes over thewlug' 3l and the 'spring' 3,3 snaps the latch into tiievspcket of the spocke't, as Qshtvn in Figures 3 and e; l ,Y
spring bie'tsed p'ai'rl '1 1 'at the epp'csite en'd of the wrench is. formed in a similar nainr wherein a spring 39 urges the spring biased fia'virl l1 into one ef the' sockets of 'the sprocket when an arin 4U ori the vend of a stein 4l of the' spring ibiased ip'awl is turned so that it is' free to pass ever a iiig 42 in air opening '4'3 into the handit bai".

What is claimed is:
In a chain socket wrench, a bar having bifurcated ends providing flanges, there being registering annular recesses in said iianges, a sprocket positioned between said pair of anges and journaled in said recesses, a square socket member extending transversely through one of said sprockets and secured thereto, a hexagonal socket member extending transversely through the other sprocket and elred the'et, each 'of said sprockets being provided with a plurality of spaced radially extending pockets, a chain trained over said sprockets and having lugs engaging said pockets, paii'f pawls slidably mounted in said bar and mountedmfornmovement into and out of engagement with the pockets in said sprockets, said pawlyk fig'e in end to end relation with respect to each other and each including a stem, there being an opening in said bar for slidably receiving said stem, said opening including an enlarged portion and a ie'ded diafie'terl portion eeiii'fig a sheuiiier therebetween, a @on spring ir'epi ed stein and abutting said "fr said pav'vl into engagement t with a attest, a cenar mounted en each pawi adjacent a Spket, said coil spring being positind iri the: enlarged 'portion 'of said opening and abutting said eolla, there being a pair or cutouts said bar Afer receiving the inner ends of said pawls, a finger positioned in each cutout,- and an secu-red to the-inner end of said pawl for engagementvWithsaid ngerf.
