To (1J/Z whom, it mxty concern:

Be it known that I, LLOYD C. BROWN, a citizen of the United States, residing at Vichita, in the county of Sedgwick and State of Kansas, have invented new and useful Improvements in Automatic Railway- Switch Adjusters; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to [o the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to apparatus whereby railway-switches may be automatically i 5 adjusted under control of an operator on a moving car when approaching the switches, the invention having reference particularly to devices that are designed to be operated by means of the car-wheels, to devices that 2O are carried by the cars, and to devices connected with the switch points or tongues that are designed to be operated by the devices that are carried by the cars.

Objects of the invention are, first, to pro- 2 5 vide improved switch-adjusting appliances that will not ordinarily be obstructive on the ground-surface and which may have actuating parts that maybe automatically elevated so as to be rendered accessible when required 3o for operation of the switches, and, second, to

improve switch-adjusting mechanism generally to the end that positive, expeditious, and economical operations of switches may be attained.

3 5 With the above-mentioned and other objects in view the invention consists of improved apparatus connected with a switchvpoint and provided with a vertically-movable device connected therewith and situated 4o adj acently to one of the track-rails, so as to be depressed by the Iianges of car-wheels, the apparatus including switch-levers adapted to be elevated to accessible positions by means of the vertically-movable device and the car-wheels, so as t'o be engaged by switchoperating apparatus carried by the cars.

The invention consists, further, in the novel parts and in the combinations and arrangements of parts, as hereinafter vparticularly described, and pointed out in the ap- 5o pended claims.

Referring to the drawings, Figure 1 is a plan view of a part of a railway-track and a switch connected therewith, illustrating the application of the invention thereto; Fig. 2, a 5 5 vertical transverse sectional view at the plane of the line A A in Fig. l; Fig. 3, a top plan of a modified form and arrangement of switchpoint and operating-arm therefor; Fig. 4, a perspective view of an inverted switch-point; 6o Fig. 5, a fragmentary plan of the modified form of operating-arm for the switch-point shownin Fig. 3; Fig. 6, a perspective view of a bracket for supporting an end of the switchlever crank; Fig. 7, Aan inverted plan of the modified form of switch-point; Fig. S, an inverted plan view of the apparatus 1n its housing, which is in horizontal section; Fig. 9, a longitudinal vertical sectional view as at the plane of the line B B in Fig. 1; Fig. 10, a 7o fragmentary diagrammatic sectional elevation showing portions of a car carrying parts of the apparatus and illustrating the manner of operating the switch-levers, the car being in central longitudinal section and the stationary and ground parts being viewed at the line B in Fig. l; Fig. 11, a vertical transverse sectional view as at the line A A in Fig. 1 and transversely of a car shown in the act of cooperating with the operative parts that are 8o located near the switch; Fig. 12, aV vertical transverse sectional view of a modified form of switch-lever crank; Fig. 13, an inverted plan view of the upper part of the switch-levers shown in Fig. 12; Fig. 14, a top plan of 8 5 part of the modified crank, and Fig. 15 is a perspective view thereof.

Similar reference characters in the several figures of the drawings designate like parts or j features. 9o

In the drawings the earth or foundations are omitted in Figs. 1, 8, 9, and 10 in order to avoid obscuring the important elements of the invention. The rail c (shown as being straight) may be curved, and the curved rail a maybe designed to form part of the straight track, the rails Z) and Z/ being modified to conform to the others, the arrangement in Fig. 1 being rather for illustrative purposes than to set up arbitrary plans. A guard-rail c is arranged opposite the rail a, as is usual, and the switch-point Z has a pivot e at its heel in the customary position with respect to the rails. In the preferred construction the point d is provided at the under side thereof with a stud j, having a pin-hole g, to serve in controlling the point.

The apparatus that is connected with the switch is mounted in a housing h, which may be made up of any suitable number of parts as may be found most expedient or desirable, and it is suitably supported in the ground between the track-rails. On the top of the housing is a ledge-like guard of semicircular form in plan, and the top of the guard is arranged in the plane of the top of the streetpaving, while the remaining parts of the housing outside of the guard are to be covered with the paving, suitable covered manholes being provided for gaining access to the interior of the housing, uncovered manholes being shown in Figs. 1, 8, and 9 at 15 and 16.

A vertical rocking shaft y' has secured thereto a crank-arm m, to which is attached a crank-pin n, having a crank-arm m attached thereto, the whole comprising the switch-lever crank, a pair of horizontally-disposed switch-levers 7c and Z, set nearly at right angles one to the other, being secured to the top of the shaft y' above the top of the housing and surrounded by the guard i, the tops of the levers normally being at rest in the plane of the top of the guard, so as to offer no obstruction above the pavement-surface. In order to prevent water or dust from accumulating in the guard Z, suitable drain-openings in the housing are provided, as at 14 in Fig. 1, and the dust or sand may be removed from the housing through the manholes. The shaft is so mounted that it may move vertically in its bearings, and consequently elevate the levers Zr and Z, secured thereto. A vertically-movable lever o is pivoted to a support p, that is secured to the housing, and one end of the lever is forked and engages the shaft j, so as to control its vertical movements while permitting rotation or rocking of the shaft, and the opposite end of the lever is connected to a presser-bar q, that is suitably mounted between the rail a and the guard-rail c somewhat in advance of the switch-point, the presser-bar normally standing with its top approximately in the plane of the top of the rail a and adapted to be depressed by the flanges of the car-wheels, and thereby elevate the levers Zr and Z. A spring r, acting on the lever o, normally holds the levers ZC and Z in their depressed positions, but may be dispensed with when the weights of the metal in the connections are properly distributed to accomplish the same results.

A suitable support s is attached to the housing and aids in supporting the switch-lever crank.

An arm 2f is horizontally disposed and is connected at one end thereof to a pivot u, supported by the housing near the pivot e of the switch-point, and a switch-rod o is pivoted to the arm and also to the stud f of the switch-point for the control of the latter by means of the arm, the free end of the arm being suitably supported, as by a guide 1, attached to the support s, and having a slot 3, in which the crank-pin n operates to move this end of the arm radially in a horizontal plane, so that the radial movements of the levers 7c and Z will cause the switch-point CZ to shift its position. A drain-pipe 2 is connected to the bottom of the housing to prevent water from accumulating and freezing therein. The crank-pin n, it will be observed, has sufficient length so as to move vertically in the slot 3 without elevating and depressing the end of the arm t.

In some cases in lieu of the stud f, the pivot u, and the rod v for connecting and operating the switch-point a point (Z may be employed, to which is secured a pivot e" for its support and control, the pivot having a squared end 5 inserted in a square hole 4 in the end of the arm t, thus providing a pivot both for the switch-point and its arm, the latter having the slot 3 in its free end and being operated in the same manner as the arm t. In some cases also the switch-lever crank may be composed of two parts formed separately, comprising a shaft j', having the levers Zr and Z secured to the top thereof and in the lower end thereof having a square socket jg, in which is slidingly connected the square upper portion of a shaft j, to which is secured `the crank-arm 6, carrying the crank-pin n', to which is attached the crankarm 7 supported in a bearing-box s. 'I'he lever 0/ is like the lever o and coperates in like manner with the shaft j to elevate and depress the levers Zr and Z, the shaft y" being supported by the housing Zt, so as to move rotatively and also vertically, while the shaft j may move only rotatively. The crankpin n is only long enough to extend through the slot 3 in the arm t.

In Figs. 10 and 11 the car-body is designated by 8, and the front platform by 9. A pair of vertical circular shafts w and w are supported by the body of the car, one at either side of the longitudinal center of the car, and obviously the shafts may be supported by a car-truck, if most convenient, in either case the shafts being near the front of the forward axle of the car. On one shaft is a long roller and on the other a similar roller the rollers being adapted to be depressed on their shafts. For controlling the rollers each one is provided with a lever y, that is pivoted at one end thereof to the car- IOO IIO

ISO

platform and connected at its opposite end to the roller, so that the roller may be free to rotate. A push-bar z is connected to the lever y and extends through the car-platform 9 and is provided with a foot-plate 10, a spring 11, connected to the lever y and supported bythe platform or otherwise normally holding the roller in elevated position.

lt will be understood that the various elements and also minor details not particularly described may be variously designed, as mechanical experience may dictate.

ln practical use when a car approaches the point of a switch that may require readjustment the proper roller or x should be depressed before it arrives at the switch-levers 7c and l, (or 7c and Z,) and when the flange 13 of the wheel 12 engages the presser-bar q the latter will be depressed and the switch-levers will be elevated, so that the proper one thereof may be engaged and operated by the depressed roller, the roller being the proper one to be depressed when the lever lc extends transversely of the track. After the lever may have been moved so as to extend longitudinally of the track, so as to shift the switchpoint, the wheel-flange will have passed over the bar g, permitting the lever to descend to its normal position, and then the roller should be permitted to ascend to its normal position. When cars pass in the opposite direction and move the switch-point by means of the wheel-'llanges, the mechanism connected with the point and also the presser-bar g will be moved idly, as will be obvious.

Having thus described the invention,what l claim as new isl.
