SPECIFICATION forming part of Letters Patent No. 640,586, dated January 2, 1900.

Application filed June 17,1899. Serial No. 720,912. (No model.)

To all whom it may concern.-

Be it known that I,WALT ER Scorr PHELPS, a citizen of the United States,residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Railway-S Witch-Operat ing Mechanism; and I do 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 the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to mechanism whereby the switch is operated by the moving motor when approaching the switch; and it consists in improved means wherewith the switch is connected and directly controlled and it also consists in improved means connected with the motor for operating the switch and connections and embracing mechanism whereby the rails are utilized as guides to insure proper contact with the ground-levers; and the in vention consists,further,in the parts and combination and arrangement of parts hereinafter particularly described and claimed.

The objects of my invention are, first, to provide reliable means whereby to operate a switch from an approaching motor or locomotive when at a sufficient distance therefrom to observe that the switch is properly adjusted as desired and which shall permit of the switch being operated independently when necessary; second,to provide operating mechanism which shall be positive in action, so as to not be afiected by either the vertical or lateral oscillations of the motor; third,to provide a switch-operating mechanism that may be constructed cheaply and be reliable in all sea sons of the year, and, fourth, to provide such devices as may be useful and durable in use in effecting a saving in time at turnouts, and whereby accidents at such places may be avoided by prompt action. These objects are fully attained in my invention shown and described herein.

Referring to the drawings, Figure 1 represents a plan view of a street-railway switch of familiar design, to which is connected that part of my invention which is the immediate adjunct of the switch; Fig. 2, a plan view of the switch-levers and connected inclosing cases; Fig. 3, a longitudinal central vertical sectional view of the levers and cases; Fig. 4,

a transverse vertical section taken betweenthe two cases and showing one casein elevation; Fig. 5, a top plan of the cover of one of the cases; Fig. 6, an inverted plan of the disk lever; Fig. 7, a transverse vertical sectional view taken on the line a; as in Fig. 3; Fig. 8, a transverse vertical sectional view of portions of a street motor-truck having a portion of my invention applied thereto; Figs. 9 and 10,front and side elevations,respectively,of the guidebar; Fig. 11, a longitudinal vertical sectional view of a portion of a motor and my devices attached thereto; Fig. 12, a fragmentary top plan of a motor-truck and portions of my devices; and Figs. 13 and 14, front and side elevations, respectively, of one of the trip-bars, by which contact with the ground-leversis made in operation.

Similar letters and numerals refer to similar parts throughout the several views.

The cases B and B, their bottoms 1 1, and the connecting-tubes b b constitute the framework of the ground-levers and connections for the switch, and the covers 2 3 afford protection thereto and participate as foundations or supports with the cases. The bodies or sides of the cases are preferably alike, as are also the bottoms, and the latter may be suitably perforated to permit the escape of water that may enter the case. I preferably cast the body and bottom separately and bolt or rivet the two together, and suitable lugs are provided for bolting the covers to the bodies. Suitable bearings, as 10 12 13 14, are provided, in which are journaled vertical shafts C D. lever G, pivoted at its center, and to it is socured or forged integrally a lever 0 extending ata right angle from the axis thereof. These two levers are preferably formed separately and both secured to a shaft C journaled in the bottom and cover of the case. In the case B is a transverse lever C, also pivoted at its center, but connected d'etachably with its axial shaft D, which has a portion 4, preferably rectangular in cross-section, and the lever has an aperture 0 corresponding In the case B is a transversev thereto, so that the shaft may rotate the lever, yet be freely inserted and withdrawn. The shaft D has a disk cap D secured thereto for the purpose of providing a frictional resistance to prevent the accidental movement of the switch-point and to retain the same in such position in which it may be placed in operation. This cap is also designed to prevent the admission of dust and water to the case around the shaft-bearing. The top of the cover 3 has a raised annular bearing 5, and the disk D has at its under side a raised annular bearing 6, conforming to that on the cover, and it also has an annular lip or flange 7, adapted to overhang the bearing 5 to prevent dust from coming in contact with the bearings. This disk is thus supported at the annular bearings at its edge, but is guided centrally by its shaft-bearing, and it performs also the function of a lever, being provided with a crank-pin E, preferably of the roller type, situated near its edge, and stops 8 8 are cast at the under side of the disk adapted to engage a stop 9, cast upon the top of the cover. At the top of the cover at the bearing 10 is a raised annular flange h, and at the under side of the disk is an annular groove 11, adapted to receive the flange h, but is slightly deeper than the flange, so that when the disk is in position upon the cover an air-space is provided abovethe flange h, so that air confined therein shall prevent water from flowing over the flange into the shaft bearing 10. The shaft D is provided with screw-threads at one portion above the square portion 4, and a threaded nut f is applied to retain the shaft within the bearing in the cover, a bearing-washer e being also preferably employed; but I may substitute a pin or set-screw for the nut. Thus the disk and shaft may be connected to the cover before the latter is bolted to the case-body. By this construction the pin E may be moved back and forth 'within the limit of the stops to swing the lever O in the operation of the switch. The cases are provided with a suitable number of apertures 15 in the sides to admit the switch-rod a, and those unused are filled by plugs c.

The cases B and B are connected,butspaced at a suitable distance apart, by means of a pair of tubes 1) I), having screw-threads at their ends entering suitable apertures and secured by means of nuts (2. In the tubes loosely are connecting-rods d d, each of which is connected at one end to opposite ends of the lever O and at the opposite ends to opposite ends of the lever C by means of jaws d,

' pivoted to the levers and preferably made adjustable by means of screw-threads and nuts. The connected cases,equipped with the levers and connections,are set in the roadwaybed, so that if in a paved street the top of the case top is even with the top of the pavement, or approximately so, and between the rails A A, so that the case B is near the switchpoint and the case B at a suitable distance therefrom in the direction from which a motor approaches the switch. The rod a is suitably connected to the switch-point A leading to the turnout A, and also to the lever 0 preferably by means of an adjustable jaw a. In a steam-railway where two switch-points are employed the rod (1 may obviously be extended through the case and connect the opposite switch-point,or independent connections may be made between the pair of points.

In Figs. 8, 11, and 12 only so much of a motor truck and frame are shown as to illustrate the relation of my appliances thereto, 7o representing carrying-wheels mounted on axles Z Z, between a pair of which I mount the main parts of my invention that are designed to be carried by the motor, so that the four wheels bearing upon the rails afford the most positive gage and support for the working of the various parts. In some cases, however, good results maybe had by mounting my devices at the opposite side of a pair of wheels. Where the trip-bar may be hung to framework which has no springs interposed between the same and the journal-boxes of the wheel-axles, the guide-bar may be dispensed with; but as such an arrangement is in most cases impracticable I provide a guide-bar to act upon the top of the rail or with slight modification from the form shown to act upon the periphery of acarrying-wheel or upon an axle, so that the trip-bar shall descend invariably a proper distance to form contact with the ground-lever when operating the switch. This function I prefer to perform and carry out by means of a pair of counterpart foundation-brackets G G, bolted to truck-frame bars F F. These brackets are provided with either fixed or detachable housings K K of identical form and H H, also of identical form, but having arms 0 0 preferably attached thereto, so as to be at opposite sides as a right-hand and a left-hand arm. Each housing K has mounted therein a vertically-movable guid e-bar J or J of identical form and provided at the lower end with a roller M. The upper portion of the guidebar has an opening at, in which is a spiral spring N, seated at its upper end against the top of the opening and at its lower end upon a bearing-platep,extending through the opening and supported at its ends by the housing K. Between the opening at and the roller M is a vertical slot m to receive the end of the compression-beam L. Thus by means of the spring N and plate p the bar is supported in the housing, which acts also as a guide in which the bar slides vertically.

Each housing H or H supports a pair of counterpart but reversed trip-bars, as I I or I I, each bar having at the upper portion an opening a, in which is a spiral spring T,

seated at its upper end at the top of the opening and at its lower end upon a bearing-plate '1), which extends through the opening and is supported at its ends in the housing,one plate extending through a pair of bars and support-' ing the springs of both bars. In the lower portion of the bar is a slot 75 of sufficient vertical length to permit the compression-beam L to have play therein when the companion bar is acting thereon, the beam L extending through all the guide-bars. Each guide-bar has a foot 1 having projecting points 16 with a beveled face 17 at one side,the beveled faces of a pair of bars being adj acently disposed, so that when one foot engages the crank-pin E the latter is drawn over toward and under the opposite foot of the pair, the amount of bearing upon the top of a trip-bar to force the same down to an operative position. The lever P may be of either the single-end type or of the double-end type, as shown, and is suitably connected at its free end, as by a ca- Jole s, to a bell-crank, as Q or Q, suitably supported and having a push-bar R or R, suitably mounted and supported at the end of the motor platform or floor S, so that the operator may press his foot upon a push-bar and operate a trip when approaching a switch and shift the same to the desired position.

It will be obvious that I may place the whole mechanism either centrally with the rails of the road or near one rail, the fixed or ground connections being in conformity to the movable or motor connections, as circumstances may require.

lhe mode of operation having been above described in detail, further allusion seems superfluous, the functions of the several parts being obvious. It may be pointed out, however, that an advantageous application of my invention provides that a push-bar is placed at the right-hand side of the motor and connected so as to shift the switch, so that the motor shall keep to theright,and the left-hand side bar will be pressed when it is desired to continue to or turn to the left-hand side of the two courses. It will be apparent that when a trip-bar I is forced down against its springpressure after moving a short distance it engages the pressure-bar L, forcing the same down and with it the guide-bar J until thelattercomes in contact with the railA,which limits the movement of the trip-bar, so that the latter strikes the pin E fairly without interfering with the disk or case or other obstruction, the case being essentially set at a proper depth relatively to the rails. Thus a positive vertical guideis provided,which compensates for all vertical movement of the motor upon provided with a horizontal disk working upon the top of the case, a vertical contact-pin secured to the disk, and a lever detachably secured to the vertical shaft within the case and operatively connected to the switch.
