SWITCH-STAND Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed January 8, 1908. Serial No. 409,836

T 0 all whom it may concern:

Be it known that we, JAMES FRANKLIN GURLEY and WILSON EDGAR LEWIS, citizens of the United States, residing at Raleigh, in the county of Wake and State of North Carolina, have invented a new and useful Switch-Stand, of which the following is a specification.

This invention relates generally to switch stands, and more particularly to that class wherein there is a cage provided into which a switchman has to enter and lock himself in in the act of opening a switch to allow a train to pass upon the siding.

The object of the present invention is to improve and simplify the construction of such appliances and to render them more certain of action and less liable to become deranged in use.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a switch stand as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification and in which like characters of reference indicate corresponding parts,Figure 1 is a view in side elevation, partly in section, of a switch stand constructed in accordance with the resent invention. Fig. 2 is a horizonta sectional view taken on the line 2-2 of Fig. 1, and

displaying the position of the parts when the switch is closed. Fig. 3 is a similar view showing the position of the parts when the switch is open. Fig. 4 is a detail view of a portion of the operating mechanism.

Referring to the drawings, 1 designates a base of any suitable material which is supported adjacent to the tracks T. Upon this base is mounted a cage which is preferably circular in plan, and is composed of properly spaced iron bars that are secured at their lower ends in a band 2 secured to the base, and at their upper ends in a roof or cover 3. On one side of the cage is left a s ace 4 forming a doorway, the sides of whic are formed by bars 5.

The doorway is adapted to be closed by a segmental door which consists of two castings 6 that are carried by a shaft 7 that extends through the base 1 at its lower end and above the roof 3 at its upper end, and carries a semaphore or signal 8 of the usual or any preferred construction. The two segments l of the door are connected by bars 9 which, when the arts are in the position shown in Fig. 3, WllFPOSitiTElY prevent egress through the doorway, this being the position that the door will occupy so long as the switch is The shaft 7 is stayed and braced by a stand ard 10 that is bolted to the base and carries a curved arm or support ll upon which is bolted two stops 12 that are undercut, as shown in Fig. 1, to receive the switch lever 13 and each stop is provided with an orifice 14 to receive a pin 15 by which the switch lever may be locked in either of its adjusted positions.

In order to render the door easy of o eration, the lower segment carries a sha t 16 upon which is mounted a wheel 17 adapted to traverse a track 18 secured to the base.

The means for effecting the adjustment of the switch tracks S consists of a trammel 18 that is secured to the lower end of the shaft and carries two slide blocks 19 that are bolted at 20 to a lever 21, the outer end of which is secured at 22 to a bar 23 that connects the switch tongues S.

So long as the main line M is open, the door 6 will occupy the position shown in Fig. 2, but should it be desired to open the switch for the purpose of allowing a train to enter a siding, the operator opens the door 4 grasps the lever 13 and throws it from the position. shown in Fig. 2 to that shown in Fig. 3, whereupon the switch tongues will be actuated through the tramniel and lever and be shifted to the position shown in Fig. 3, thereby opening the switch. In this act the door is moved opposite the doorway 4 so that egress therefrom is impossible without first throwing the switch lever to the position shown in Fig. 2, whereupon the doorway will be opened.

It will be noted by reference to Fig. 3 that the door is considerably greater in length than the width of the doorway and this arrangement is adopted in order to render it impossible for the switchman to partly close the switch and then leave the cage as the length of the door will prevent this, as by the time the door is fully 0 on the switch will have been entirely closcdi The advantages arising from the use of the traminel with the switch tongue operating means is that it dispenses with the employment of gears, which are objectionable owing to the fact that they become rusted and thus tit) diliieult to 0 )crate. By the employment of the trammel greater ease of action at all times will be secured as there will be no such close fitting between the slide blocks and the 'uides as will at any time cause the parts to become rust locked.

What is claimed is 1. I11 a switch stand, a cage having a doorway, a segmental door shiftable with relation to the doorway, a shaft upon which. the door is supported, a tramn'iel carried by the shaft, switch tongues, and a connection between the tranmiel and the switch tongues.

In a switch stand, a cage provided with a doorway, a shaft disposed within the cage and extending above and below the same, an

arm secured to the base of the cage through which the shaft rejects, a shifting lever secured t0 the she t and arranged to traverse the arm, a trammel carried by the shaft,

switch tongues, and a connection between the trammel and the switch tongues.

3. A switch stand comprising a cage provided with a doorway, a segmental cage-like door for opening and closing the doorway, a roller for supporting the door out of contact with the base of the cage, a shaft to which the door is secured, a switch lever secured to the shaft, a trannnel secured to the lower end of the shaft exteriorly of the cage, switch 30 tongues, and a connection between the trammel and switch tongues.

In tcstii'nony that we claim the foregoing as our own, we have hereto affixed our signa tures in the presence of two witnesses.
