NITED TATES CHARLES S. HOENES, OF MILWVAUKEE, VISCONSIN.

AUTOMATIC RAI LWAY SWITCH.

SPECIFICATION forming part of Letters Patent No. 511,425, dated December 26, 1893. Application filed December 17, 1892 Serial No. 455.512- (No model) To all whom it may concern.-

Be it known that I, CHARLES S. HOENES, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and and is especially adaptedfor use on thosestreet railways on which cars are run by elec tricity by the overhead trolley line system.

In the drawings, Figure 1, is an elevation of my improved device, parts being broken away to show interior construction, in connec- 'tion with a fragment of a car necessary to show the relation of a car tothe device. Fig.- 2, is aplan view on ,line 2-2 of Fig. 1 of so much of my device as is, not carried on the car, parts being broken away for convenience of illustration. Fig. 3, is a detail in vertical section, of the switch point. Fig. 4, is a de tail of actuating and stop mechanism attached to and connected with the rock-shaft.

The carAof which only one corneris shown, is of such form and construction asis in common use. The single rail B of the railway track in connection with the branch or shunting track B and thepivoted and swinging switch point 0 are substantially such as are in common use, these constituting a sufficient portion of the track and the switch to illustrate my invention.

The switch point 0 is provided at its end that abuts against the branch track B with a rigid pintle or pivot pin D by and through which the switch point is pivoted in position, conveniently and usually by being inserted downwardly through the switch plate E integral with or rigid to therail B and branch rail 13', Below the switch point and extending to a distance outwardly therefromand preferably in an oblique direction, is a subway or chamber F.

stepped or footed revolublyin a block on the The pintle D, for steady-- ing and supporting its bearing, is preferably I bottom of the chamber. The pintle is provided with oppositely extending rigid radial arms G G, and suitable connecting devices J J (rods or chains) connect the extremities of these arms with the corresponding extremities of the oppositely extending radial arms H H secured rigidly to the vertically extending rock-shaft I. The rock-shaft I is stepped or footed in the bottom of the chamber F and projects upwardly preferably to a distance somewhat exceeding the height of a car, and is supported, having hearings, in a suitable post K therefor,w,hich post may be,-and as shown in the drawings is, such an open frame steel standard as is now used for supporting the trolley wires, on arms extending there-from over the track or line of travel of the car. At a suitable height above the ground and preferably about as high as the roof of the car, two 0ppositely extending radial arms L L are secured rigidly to the rook-shaft I, one a little above the other, and the extremities of these arms are respectively connected by links M M, to the swinging arms N N medially. The arms N N are pivoted and thereby supported at their inner ends on the post K, and are so arranged as to be always: at an oblique angle to the axis of the radial arms L L',the angle of obliquity being greater or less with respect to each swinging arm as the positions of the device are changed in use, by which obliquity of position provision is made for surely and easily transmitting the motion of the swinging arms N N to the radial armsL L and their rock-shaft. These swinging arms N and N are also preferably so arranged that when thrown outwardlytoward the railway track they still are somewhat inclined toward the track in the direction of the motion of the car by which they are to be actuated. The post K stands at the side of the track at a little distance therefrom and the arms NN extend therefrom toward the track andpreferably terminate in downwardly and upwardly turned extremities O 0 respectively. v

A laterally projecting arm Pvis secured to the car adjustable vertically conveniently by means of the rod R of which the arm P is the overturned integral extremity. The rod B is secured in guides or ways therefor on the car and is provided, as a desirable means of looking it in position vertically, with a swinging gravity latch S arranged to engage a rack 'l fixed on the car. This rod R and arm P may. be secured to the car at its front or rear end so as to be elevated or lowered to contact with the arm N or l as desired, either by the motor man at the front of the car or by the conductor at the rear of the car. By reference to Fig. 2, it will be readily understood that the switch point C will be shifted to guide the car on to the main track or to the branch as desired by throwing the arm P on the moving car temporarily into contact with the arm N or N as the car passes them. a

For obtaining a slight amount of positive movement of the rock-shaft, and resultingly of the switch point, independently of the ac? tion of the arm l, and for locking the rockshaft yieldingly in position, I provide an enlarged collar U on and secured rigidly to the rock-shaft I, which collar has two faces U U meeting each other at an angle, against which a spring V bears. The spring V is secured at one end rigidly to the post K its free end bearing against a face U. It will be seen by reference to Fig. 4, that this spring V bearing on a face U of the collar U, locks the rockshaft yieldingly in position revolubly, and when the rock-shaft is rotated to such extent as to shift the angle at the junction of the faces U to the other side of the right line projecting from the spring through the axis of the shaft, the power of the spring will act to continue movement of the shaft slightly and will then look it in its new position, the spring bearing against the other face U.

To obviate the entry of water from the surface of the street into the chamber F about the pintle D, an annular boss or flange \V is raised on the switch plate E about the head of the pintle D which enters a corresponding groove in the under surface of the switch point C. For a similar purpose a circular hood or collar Y, water tight on the rock-shaft I, projects over a boss or flange Y on a plate at the surface of the street through which the rock-shaft passes into the chamber F.

As the switch point C is only to be shifted for shunting a car when it approaches it coming toward its sharp pointed end, the car moving in the direction of the arrow on Fig. 2, it is desirable that the post K should be located at a distancein front of the switch point, substantially as indicated in Fig. 2, so that the switch point will be shifted by the contact of the arm P with one or the other of the arms N or N before the car arrives at the switch. The chamber F is provided with a discharge duct X for transmitting therefrom any water that may get into it.
