SWITCH-STAND.

SPECIFICATION forming part of Letters ratent No. 669. 1 dated March Application filed December 6, 1900. Serial No. 38,873. (No model-) T0 61/ whom it may concern.-

Be it known that I, JOHN WRIGLEY, a citizen of the United States, residing in Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Switch-Stands; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to the reference characters marked thereon, which'form a part of this specification.

This invention relates to railroad-switchoperating mechanism, and it has reference particularly to that class of switch-operating mechanism which is used most commonly in controlling sidings, being operated by a weighted hand-lever adapted to be thrown over to either of two positions to open or close the switch, as the case may be.

The object of the invention is to provide a mechanism of this nature which shall be simple and compact in construction, positive and easy in operation, proof against becoming clogged in the connections between its moving parts by water freezing upon them, and capable, in having its parts arranged so as to be interchangeable and reversible, of ready adaptation to either side of the road-bed.

The invention consists in the improved railroad-switch-operating mechanism constructed substantially as will be hereinafter particularly described, and finally embodied in the clauses of the claim.

In the accompanying drawings, Figure 1 is a plan view of a railroad-switch andof my improved switch-operating mechanism. Fig. 2 is a view in end elevation of said switchoperating mechanism, a portion thereof being removed. Fig. 3 is a side view of the invention. Fig. dis a horizontal sectional view on the line m m in Fig. 2. Fig. 5 is a view in end elevation, partly in section, of a modified form of the invention; and Figs. 6, 7, 8, and 9 are plan views of several different forms of one of the parts of the mechanism.

In said drawings, a designates the main rails and b the switch-points, the latter being connected in the usual manner by rods 0.

f designates a detector-bar which is pivotally secured to the free ends of links g, that are in turn pivoted on clips 7t, secured to one of the rails. The detectorbar serves the usual purpose of preventing the throwing of the switch while the train is partly on and partly off the same.

i denotes my improved switch-operating mechanism, thesame being preferably secured upon the end of one of the ties adjacent the switch.

I prefer to inclose the working parts of the mechanism as much as possible, so as to protect them against disarrangement by accident or from being clogged by snow or ice produced by water freezing upon them, and for this purpose I provide a casing j, which affords a support for said working parts. Said casing is preferably rectangular in form and comprises two sections is Z, the section It being adapted to rest immediately on the tie or other suitable support, while the section Z rests on said section 76, being provided with a top or cover portion 'm. The two sections are secured together by means of bolts n, which engage corresponding integral projections 0 of said sections and which in their middle portions are formed in semicylindrical shape, as at 19, so as to produce a hearing between each two such corresponding cylindrical portions for a trunnion q. The section 76 is adapted to be secured to the tie by spikes in the usual manner, integral flanges r, having spike-openings 3, being formed at the base of said section on two opposite sides thereof for this purpose. There are two of the trunnions q, the same forming longitudinal extensions of a cylinder 25, said cylinder being inclosed within the casing and having a cam-slot u formed spirally therein..

1; denotes a lever, which comprisesa sleeve portion 20 and two arm portions 00, one of said arm portions projecting from one end and the other from the other end of said sleeve portion on opposite sides thereof. Said sleeve portion of the lever has trunnions y, which are journaled in integral inwardly-extending projections z of the two sections of the casing. One of the arms w of said lever is provided with a pin 1, which engages the slot u in the cylinder, while the other arm m projects through a horizontal opening 2 formed in the casing. .In order to thoroughly protect the mechanism Within the casing, I provide the upper section thereof with a downwardly-extending lip 3, which overlaps the joint-line between the two sections onthree sides of the casing. On the fourth side, since it would be impracticable to associate the parts if the opening 2 for the lever-arm were in the form of an orifice in one of the sections and in order at the same time to preserve the joint arm of the lever, so as to Work therewith.

The slide may be disposed either on the inside or the outside of the casing of course. The outer arm 00 of the lever 12 carries a pin 8, to which is pivotally secured the free end of the rod 9, which connects the switch-points with said lever.

10 is an integral arm, which projects from the upper casing-section land which is formed with a vertical sleeve portion 11, which provides bearings for a spindle 12, that is sustained against downward movement in the sleeve by a collar 13, which rests upon the top of the sleeve. This spindle may carry at its upper end a target, lamp, or other signaling device 13, while its lower end is provided with a crank 14;, having a slot 15, which receives the pin 8. Thus as the lever 01 is shifted the motion is transmitted to the signaling device as well as to the switch-points, both being set simultaneously. Each trunnion q protrudes from its bearings. One of these trunnions carries a crank 16, which is removably secu red thereto by a pin 17, which penetrates the crank and fits in a cross-cut 18 in the trunnion. This crank and the detector-bar are pivotally connected by a rod 19. The other trunnion carries an arm 20, which is removably secured thereto in the same manner as is the crank 16 to its trunnion, said arm being adapted for turning the cylinder to operate the mechanism and being provided, as usual, with a weight 21.

It will be of course understood that either or both of the extremities of the slot to in the cylinder 25 may be so formed that for a short distance the slot will extend at right angles relatively to the axis of the cylinder, so that when the pin of the lever is engaging this portion of the slot the mechanism will be positively locked against operation except by turning the cylinder. The drawings Figs. 4, 6, 7, 8, and 9 show cylinders having various forms of slots.

In the use of that form of the cylinder which is illustrated in Figs. 4 and 9, where both exthe wheels of a train can move the switchpoints some part of the mechanism must be broken, and before even a manual operation of the cylinder can be effected the entire train must clear the detector-bar.

In the modified form of my invention shown in Fig. 5 instead of providing a lever v of the shape of that already referred to I employ a straight lever 22, fulcruming the same upon a vertical stud 23 of an integral projection 24; extending inwardly from one of the walls of the casing-section 70. In other particulars this form of my invention is substantially like that already described.

It is preferable that the flanges r be provided on each side of the fulcrum of the arm 20 with a stop 25 upon which said arm may rest as it is thrown-over from oneposition to the other, for without this the cylinder would soon have such arange of movement that the pin would be engaging the end of the slot to theinjury of the mechanism, as when, for instance, the arm had nothing to take against afiording more substantial resistance-than the tie or the road-bed.

By arranging the several parts in the manner which I have above described they are made so that the mechanism can be'placed upon either side of the road-bed as desired. This can be done-either by removing theupper section of the casing and reversing the parts or by interchanging the arm n and the crank 16.

It is to be observed that the detector-bar is raised to its most elevated position at the middle point of movement of the rotary parts. Thus at each limit of its movement it is at its lowest position-i. 6., in such position that the switch cannot be'operated so long asa Wheel is over the-detector-bar.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with asuitable casing, of a lever fulcrumed in and projecting into said casing at one of its ends, a cylinder having a spiral slot and journaled within said casing, said lever having a projection at its inner end' engaging said slot, a signalcarrying spindle journaled in said casing, and a crank carried by said spindle, said crank and the outer end of said lever being contiguous to each other and the one having a slot and the other a pin engaging said slot, substantially as described.

2. The combination, with asuitable casing comprising separable sections, ofa lever fulcrumed in and projecting into said casing at one ofits ends, a cylinder having a spiral slot and journaledin said casing between theseceasi tions thereof, the inner end of said lever having a projection engaging said slot, a signalcarrying spindle jou rnaled in said casing, and a crank carried by said spindle, said crank and the outer end of said lever being contiguons to each other and the one having a slot and the other a pin engaging said slot, substantially as described.

3. In a switch-operating mechanism, the combination, with a lever adapted to be opera tively connected to the switch, of a casing comprising separable sections disposed the one above the other, said lever being fulcrumed in one of said sections and project ing into the casing at one end, a cylinder having trnnnions and inclosed in said casing, the trunnions of said cylinder being journaled in the casing between the sections thereof and said cylinder and the inner end of the lever having a slot-and-pin connection between them, a crank and operating-arm removably carried by the respective trunnions,said crank being adapted to be connected to a detectorbar or other similar part, a signal-carrying spindle journaled in a portion of said casing,

and another crank carried by said spindle, said crank and the outer end of the lever being contiguous to each other and the one having a slot and the other a pin engaging said slot and said outer end of the lever being adapted to be connected to the switch, substantially as described.

4. In a switch-operating mechanism, the combination of a casing comprising separable sections disposed the one above the other, a suitably-fulcrnmed lever projecting into said casing, one of the walls of said casing having a slot for said lever, a slide covering said slot and movable with the lever, and means for operating said lever inclosed in said casing,

the upper casing-section having a flange overlapping the joint between said sections, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of November, 1900.
