drawings, I have, for convenience, shown my lmproved connecting rod in connection with a switch and switch throw of conventional design. In Fig. 1, main track rails are indicated at 10 and side track rails at 11.
At 12 are shown coacting switch points and connecting these switch points to move in unison is a tie bar 13. The switch is shown closed, the switch point at the right of the figure being moved away from the adjacent main track rail. In the open position of the switch, the switch points are, of course, shifted to a position reverse to that illustrated. The base plate of the switch throw is indicated at 14, this plate being spiked to one of the track ties and journaled upon the plate is a-customary switch throw lever 15. Coming now more particularly to the subj ect of the present invention, it will be seen that I employ coacting telescopic rod sections 16 and 17, the section 16 being solid and the section 17 being hollow. At its forward end the section 16 is provided with a yoke 18 bolted to the adjacentend of. the tie the section 17 areIprovided spacedalined bearings 19 and 20 slidabl'y receiving the bearing 20; the section 17 is, as'shown in detail in Fig. 6, formed with asquared porupon the section 16' within the portion 21* of with the bearing '20' for preventingrseparaand varying the effective length of the rod.
Formed in the cylindrical portion 22 0f the rod section 17 are registering ;slots 24; and 'slidable within said section is a hollow plunger 25 open atits forwardend to re ceive the rear end of the rod section 16and provided at its. rear end with a headg26.
The plunger is, as shown in Fig.f6, substantially rectangular in cross section to freely fit within the portion'21of the section 17 of the" rod but is.,-however, provided'with rounded corners to also freely fit, as shown in Fig. 7, Within the cylindrical portion 22 nearly approaches the wall of the portion 22 forcentering the inner "end of the plunger with respect to said wall. Formed in the plunger'at opposite sides thereofare registering slots 27 alining with the slots 24 of the "rod section 17 and extending freely through all of said slots is a pin 28 which, as shown in Fig. 7, is fixed to the switch throw lever 15. Preferably, a washer 29 is arranged between said lever and the rod section 17 while upon the outer end portion of --the pin; is mounted a second washer 30, a
cotterpin being arranged to coac't between I this washer and the pin for securing the rod uponthe pin. At its outer end, the'rod sec tion 17, is, as particularly'shown in Fig. 8,
formed with oppositely disposedlugs 31 d-irected inwardly toward the axis of said section-and arranged to coact with said lugs is a removable closure plug 32. This plug is provided with an annular radial base-flange 33 freely fitting within 'theouter end portion of the mod "section 17 and formed in said flange are diametric'notches 34 adapted to 'freely receive the lugs '31. Rising from the flange are pairsof reinforcing ribs 35, each :pair of ribs receiving one of the lugs therebetweenrespectively. 1 Accordingly, the ribs "will 'coact with the lugs for locking the plug againstrotation and bearing between said i plug a'ndthe head 26 of the plunger 25 is a "coil spring 36 housed withinsaid rod section; As will be perceived, the 'p'lugmay be depressed: into the-rod section against the tension 'ofsaid spring until'the ribs 35 clear the -lugs 31 when the plug may then be rotated to bring the notches 34: into register withsaid lugs. In this position of the plug, saidrplug may, of course, be removed to per- In'it removal of the spring 36 and plunger 25.
In 'thisconne'ction, it is to be observed that the' rodse'ction 17 is provided with an en-' larged rear terminal 37 to accommodate the 'clug, said terminal carrying the lugs- 31. The
lugs areaccordingly spaced away from the axis ofthe rod section so "as to lie substantially flush 'attheir inner ends with the inner'face of the wall of the'portion 22 of the -section whereby the head '26 of the plunger ,may clear said lugs, I accordingly provide a construction wherein the rod may be readiily assembled or disassembled.
of theprecedin'g description, the spring'36 qwi-ll normally maintainthe "partsin'the posi-z A's wi11 nowbe readily un'der'stoodin view tion shown in-Fi'g. 2, so that the switch throw lever-1 5 may be swung to Shiftfthe switch "points 12 for-opening -or closing "the switch. However, w hen'the switch is closed, as shown in Flg. -1,it will be seen that the I switch points may 'move "for drawing the rod section 17 forwardly over the pin 28, as shown in Fig- 3, and compressing the spring shown in Fig. 5, serve to telescope the rod.
