ROD FOR CONNECTING RAILWAY-SWITCH STANDS TO THE SWlTCH.

SPECIFICATION forming part of Letters Patent No. 317,617, dated May 12, 1885.

Application filed April 7, 1885.

To all whom it may concern:

Be it known that l, J AMES BRAHN, a citizen of the United States of America, and a resident of Jersey City, county of Hudson, State of New Jersey, have invented a certain new and useful Improvement in a Rod to be Used in Connecting a Switch-Stand to a Railway- Switch, of which the following is a specification.

Figure 1 is a plan, and Fig. 2 is a section of the same connected to a lever.

My invention consists of a railway-switch connecting-rod containing the devices and conbination of devices hereinafter described and claimed,whereby the proper adjustment of the switch-rails with the permanent rails of the track can be maintained.

is an elongated eye, one end of which is formed sufficientlylarge to have ahole formed in it at right angle with the eye ,and threaded to receive the threaded end of rod. F, asshown in Fig. 1.

D is a jaw, the closed end of which is sufficiently large to have a hole parallel with the 2 5 jaw and threaded to receive the opposite end of rod F. Rod F is usually one and one-quarter inches square, rounded at the threaded ends to one and one-quarter inches round.-

E is a bar secured to the movable end of the switch-rails, and'connected to jaw D by apin or bolt, as shown in Fig. 1, while eye 0 is secured to the crank at the bottom end of the shaft of a switch-stand. Eye 0 is elongated about one-half inch, so as to have about onehalf inch lateral motion on the crank-pin of the switch -stand. The crank of the stand should have about one-half inch more throw than the switch-rails are intended to movelaterally. Thus the movement of the connecting-rod and the switch-rails are equal. Should the track spread, or lost motion from wear of the switch -rails and connections require a greater movement of the connecting-rod to move the switch-rails sufficient to make a per- (No model.)

fect connection with the permanent rails of the track, the movement can be increased by screwing rod F into eye 0, so the end of the rod will protrude in the eye and take up a part or all of the lateral movement of the eye on the crankpin, and thusincrease the move ment of the rod equal to the protrusion of the end of the rod in the eye. Should the rod re quire to be longer, it can be made so by screwing jaw D partly off of rod F, and it can be shortened by screwing the jaw on the rod.

By the foregoing arrangement the switchrails can be quickly and perfectly adjusted to the permanent rails of the track in all kinds of weather, and thus lessen the liability of derailment of trainsin consequence of the switchrails being out of adjustment with the permanent rails of the track.

lVhile I have described a crank switch-stand to be used with this rod to operatethe switch, yet I do not wish to confine myself to a crankstand, as eye 0 can be used with a lever, as shown at G, Fig. 2.

Having th us described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a railway-switch and a switchstand, a connecting-rod having an elongated eye, 0, arranged to operate as and for the purpose described.

2. In combination with a railwayswitch and a switch-stand, a connecting-rod having an elongated eye, 0, and jaw D, all constructed and arranged to operate as and for the purpose described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 31st day of March, 1885.

JAMES BRAHN.
