1 Claim. (Cl. F75- 376) This invention appertalns to a wire leader for drawing` iiexi-ble elements, such as electric conductors or wires, through conduits and has for its primary object to provide means for effecting a facile and convenient replacement of a `lead wire for a vehicle horn. f
lAnother object of this invention is to provide an elongated exible tool and to provide means for detachably connecting onel end of a wire or similar element thereto, so that the-wire or cable can Ibe easily drawn by the tool through a conduit or similar member.
These and ancillary objects are attained by this invention, the preferred embodiment and one environmental use of which is set forth in the following description and illustrated in the accompanying drawing wherein: v
Figure l is a fragmentary longitudinal sectional view of the tube and worm assembly of the steering mechanism of a conventional vehicle, illustrating a tool, constructed in accordance with the principles of this invention in use to dispose a horn wire therethrough;
Figure 2 is a viewv similar to Figure 1 with the horn wire shown in a position, after being drawn through the worm assembly;
Figure 3 is a detailed side elevational view of the means for connecting the tool to the wire;
Figure 4 is a top plan view of the ,connecting means;
Figures 5 and 6 are perspective views of the parts of the connecting means;
Figure 7 is a longitudinal sectional view taken -on line 1-1 of Figure 4, and
Figure 8 is a perspective view of the handle for the tool.
With continued reference to the accompanying drawing, the tool I0. which is especially designed and adapted for drawing cables, wires, or similarv flexible elements through conduits or similar housings, includes an elongated flexible cable I2, which constitutes the shank portion. An arcuate handle I4 is transversely iixed at the center of its irmer convex side to one end of cable f I2, the handle .being hollow and having an axial slot I6 formed in its outer side to provide means for receiving and retaining the cable, when it is coiled for storage.
Means is provided for detachably connecting the opposing end oi the cable I2 to a wire, such as the lead wire IB ior a horn. as illustrated in I ,the drawing. The connecting means 20 includes a socket member 22, which is permanentlyaffixed to the end of the cable. The 'socket member I2 consists of a collar 24 which is iixedly circable. An inof the sleeve. Biiurcated outwardly'curved resilient fingers '30 overlie the inner end of the guide and are formed at their outer ends with grooves 32, defining a socket with the inner portion of the guide.
Opposed lateral arms 36 and 38 extend integrally from the side edgesof the guide and inherently resilient confronting clamping bars 40 and 42 are carried by the outer ends of the arms, the bars paralleling the side edges of the guide. Inwardly extending inner ends 44 'and 46 are formed on the bars and the outer ends are curved outwardly.
A ball 48 forms the other part ofthe connecting means and is detachably fixed on an end ofthe wire I8 or similar element, the bali having a sleeve 50 formed integral therewith and axially split to receive the end of the wire. Thus, the sleeve is expandable to accommodate various sizes of wires or similar elements which have one of their ends clampingly engaged therein.
'Ihe ball 48 is adapted to be axially moved in the guide. through the opposing clamping bars and into engagement with the nger 3,0,the ends 44 and 46 of the bars engaging the ball. as seen in Figure 4, to prevent accidental dislodgement thereof from the socket.
In the use illustrated in the drawing, vthe horn wire I8 has one of its endsattachedto the ball 48 and the ball is attached in the socket; member, after the cable I2 is pushed through the tube 52 of the steering assembly. By moving the cable I2, effected by grasping and pulling the handle I4, the wire I8 is pulled through the tube and the diiiiculties normally encountered in trying to thread the' wire I8 through the tube are obviated.
Of course, the tool I0 can be dependably employed for use in other environments, where it in said socket, and said socket comprising a collar axed to said tape, an enlarged sleeve portion formed integrally with said collar, said sleeve portion having a longitudinally extending slot extending inwardly from its outer end, a Ipair of 5 outwardly curved resilient ngers formed integrally with said sleeve portion and extending from the inner end of said slot, a pair of lateral arms foiredgfiiitegrally' with sai'dgsleeve portion. at either-"Sidof said slot, and a clamping loar formed integrally with the outer end of each arm and having inturned inner ends, whereby said ball may be yieldably held by said fingers and said inner ends of said bars.
