SWITCH STAND.

T 0 all whom it may concern: 7

Be it known that I, ARTHUR M. CoRNELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Switch Stands, of which the following is a specification.

My invention relates to an improvement in the type of high or main-line switchstands, as distinguished from low or yard switch-stands; and it is fully described and explained in the specification and illustrated in the accompanying drawings, in which Figure 1 is a broken view in elevation of a main-line switch-stand embodying my improvements; Figures 2 and 3 are sections, respectively on line '2-2 and 3--3, Fig. 1, and Figure 4 is an enlarged broken sectional View on line H, Fig. 3. 7

My improvement relates primarily to the construction of the crank-mechanism at the connecting it with the switch is applied; and to the relation to the crank of the recessed table, with which the hand-operated throwlever engages to hold the switch in ltS thrown position.

The frame of my improved switch-stand need involve no features of novelty, that shown being of ordinary construction com prising a pair of

legs

5, 5, surmounted by a table 6 containing

recesses

7, 7 in its edge to receive, and retain at the opposite ends of its throw, the operating lever 8 pivotally connected with a head 9 above the table and secured to the rotatable targetshaft 10, which works through a central opening ll. in the table and carries a target 12, the shaft terminating at its upper end in an angular tip 12 for setting the semaphore-lamp (not shown).

The target-shaft has its lower end formed to be integral with the shaft, preferably by forging, into a double-crank having each of its arms 18, 13, which extend at 180 degrees apart, formed with an upright stud 14 on its outer end; and centrally between these arms, a socket 15 (Fig. 4) is formed in the enlarged end of the shaft to receive a pivotstud 16 projecting from the bed-plate 17 of the stand, to which its legs 8 are riveted through their feet, this pivot-stud, which may be lubricated through the duct represented at 15 forming the axis about which the shaft is turned for throwing a switch (not shown) through the medium of a connecting-rod 18 having one end attached, as usual, to the switch-rail and its opposite end journaled on one or the other of the studs 14. The usual guards, shown at 19,

afford stops against accidental rise of the head of the connecting rod ed a stud '14 of the target or lamp, by merely applying the connecting rod 10 to one of the studs with the stand at one side of the track and tothe other stud when placing the stand on the opposite side thereof, since thereby the throwing of the switch and the semaphore-showing by turning the target-shaft will be the same on either side of the track. Moreover, the double-crank, by enabling the aforesaid placings of the stand, brings in either position thereof the back 6 (see Fig. 2) of the table nearest the track thereby permitting the operator. to manipulate the throw-lever 8 without getting between the stand and the track for the purpose and guarding him from obvious danger of accident in that position.

By providing the pivotal connection shown and described between the target shaft and the bed-plate, with the socket 15 centrally in the enlarged lower end of the shaft and the pivot-stud 16 on the bed-plate, not only does the construction enable the stud-carrying double-crank to be readily formed on the shaft by the desirable forging operation in suitable dies, but the bearing is thoroughly housed and protected against the elements and against access to it of gritty substances which would induce wear and resultant impairment of the switch-throw.

I realize that considerable variation is possible in the details of construction herein shown and described, and I do not intend to limit my invention thereto except as pointed out in the appended claims, in which it is my intention to claim all the novelty inherent in my invention as broadly as permissible by the state of the art.

I claim:

1. A switch-stand of the character described, having a double-crank on the lower end of thetarget-shaft with integral crankarms extending at 180 apart and each proat 180 apart. and each having formed 10 theroii an upright connecting-rod stud, said shaft containing a socket in its lower end midway between said arms, a lubricant duct leading in the target-shaft to the socket, and

a bed-plate carrying the stand and having; 15

a pivot-stud projecting into the socket.
