.20 (iv/.6 whom. it may concern.-

Be it known that 1, JOHN GEoRen ROBIN- sON,a subject of the King of Great Britain and Ireland,residing at Fairfieldmear Manchester, in the county of Lancaster, England, have invented Improvements in and in Connection with the Steps of Railway and Tramway Oarriages and other Like Vehicles, of which the following is a specification.

According to this invention a railway. or tramway motor car or carriage or other vehicle (hereinafter referred to as a car is furnished with steps which when in use extend from the car in a suitable position to enable passengers to conveniently enter and leave the car at level crossings and similar places that are without platforms and are adapted to be moved from said position into an out-of-theway position, means being provided whereby it is insured that so long as the steps are in their in-use position the brakes of the car are held on and cannot be taken off until the steps are moved into their out-of-the-way position. The steps may be locked in their out-of-theway position,so as to prevent them moving,and thereby possibly fouling, any obstacle when the car is in motion, and the locking device employed may be so arranged that the unlocking of the steps puts on the brakes and causes them to be maintained on until the steps are again locked in their out-of-the-way position, which operation releases the brakes so that they can be taken off.

The improved steps according to this invention comprise treads mounted at their ends to turn on suitable supports fixed to two sides or wings (hereinafter termed wings) that turn on vertical or approximately vertical pivots secured to the car underframe. The two wings are or may be connected together not only by the treads, but by a rod or rods, so as to insure uniform movement, the arrangement being such that when not in use the wings extend beneath the underframe in the direction of the length of the car, the treads being one above the other, while when in use the wings extend transversely away from the car,the treads being in proper position for use. There may be provided a hand-rail so pivotally connected to one of said wings and to the carbody that when the steps are in their out-ofthe-way position it lies close to the adjacent side of the car.

Figures 1, 2, and 3 of the accompanying illustrative drawings show in front elevation, vertical transverse section, and in plan, re-

spectively, a-portion of a steam-motor car furnished with steps according to this invention, the steps being in position for use. Figs. 4, 5, and 6 are similar views to Figs. 1, 2, and 3, respectively, showing the steps in their outof-the-way position. Figs. 7 8, and 9 are detail views, to a larger scale than that of the preceding figures, showing the right-hand end portion of the lowest step. Fig. 10 is a diagram showing a complete car with steps and brake mechanism. Fig. 11 is a detail view showing a modified construction.

In the construction illustrated in Figs. 1 to 9 the Wings (0- of the steps are formed with extend through corresponding holes g, formed in the adjacent ends of the treads /1., so that the treads are between the flanges 7' of the supports or bosses f and rest on the lower flanges and are prevented from rising by the upper flanges while free to rotate about the supports or bosses. The steps in the example shown have three treads it, and for the purpose of placing the treads in position between the flanges of the annular supportsfthelower flange 'of each such support is made separate from the shank and upper flange thereof, the two portions being connected by screws 713-. The upper portion of each of the two lower step-supports is made in one with the lower flange of the support of the adjacent higher step. The wings a are each constructed in three pieces of sheet metal connected together by the annular supports f to flanges or webs m, to which. the sheet-metal wing portions are riveted. The lower reaiwvardly-exending lug b has fixed to it a rearwardly-extending arm 0, and a rod 19, freely pivoted at each end to the outer end of said arms, connects the two wings, so insuring their uniform movement. A fixed hand-rail (1 extends vertically down each side of the door-frame to the footboard r, and pivoted to a knuckle-piece a, mounted to rotate and slide on the right-hand side fixed hand-rail g, is one end of a hand-rail 6', whose other end is pivoted to another knucklepiece a, that is itself pivoted to the upper end of a newel-post w, the lower end of which is carried by and can turn freely in a socket 517, secured to the right-hand wing a. An arm Each wing is provided with or bracket y, fixed to the end portion of the lowest step it, is also fixed, as by a cotter a, to the lower part of the newel-post w, so that the bent upper part of the post 21) is always caused to extend outwardly whatever the position of the steps. The upper part of the newel-post w is outwardly bent in order to clear the underframe of the vehicle or lower part of the car-body when the steps are in the out-of-the-way position. In order to steady the newel-post, it extends through and freely rotates in the end of a stay 1, fixed to the corresponding wing.

The wings a move through an angle of approximately ninety degrees when the steps are moved from the one extreme position to the other. In their in-use position (see Figs. 1, 2, and 3) the wings a extend transversely from the side of the car, with the treads it displaced laterally from beneath each other, so as to be convenient for a person to walk up or down them, while when the steps are in the out-o'f-the-way position the wings a extend in the direction of the length of the car below the underframe, (usually beneath the sole-bar 2, as in the example illustrated,) the wings a being in one common vertical plane and the treads it one above the other, but displaced longitudinally. (See Figs. 4, 5, and 6.)

An arm 5, fixed on a short rock-shaft 6, that is mounted in brackets 7, fixed to the under side of the upper tread 7b, is adapted to be moved by a downwardly-extending handlever 8, fixed on the rock-shaft 6, the arm 5 in one position extending upwardly through a slot 9 in the upper tread 72 and behind a bracket 10, that is fixed to the underframe 2, so as to lock the steps in their out-of-the-way position.

To prevent the hand-lever 8 from accidentally moving from the position to which it is moved when the steps are locked, Fig. 4, or unlocked, Fig. 1, the hand-lever is furnished with a spring-pressed ball 8, adapted to enter one or the other of two depressions 7, that are formed in the bracket 7.

To securely hold the steps in their in-use position, the notched inner end 11 of a springpressed catch-lever 12, pivoted at 13 to a bracket 14:, carried by one of the wings a, is adapted to engage a suitably-shaped part15, fixed to the adjacent downwardly-extending bracket d when the steps are in their in-use position. To release this catch, achain 17 is connected at one of its ends to the outer end of the catch-lever 12 and to an arm 18 on the before-mentioned hand-lever 8, so that by suitably moving the hand-lever 8 the catchlever 12 is pulled by the chain 17 against the action of its spring 19 out of engagement with the fixed part 15, so that the steps can then be moved into their out-of-the-way position by forcing them to the right, it may be by pressing the hand-lever 8 in the desired direction.

are vertically arranged, the steps are not liable to collapse while in use. i

For the purpose of putting on the brakes when the steps are unlocked and moved into their position for use and for holding on the the brakes until the steps are again locked in their out-of-the-way position a lever 20 21 is pivoted at 22 to the fixed bracket 10, behind which the locking-arm 5 extends when the steps are locked. The arm 20 of said lever is located in the path ofthe locking-arm 5, and the arm 21 is connected, as by a Wire 23, to a valve (indicated digrammatically at 24C, Fig. 10) in connection with the train-pipe 25 ot' the vacuum or air-brake apparatus 26 of the car, so that the locking-arm 5 cannot be moved clear of the fixed bracket 10 to release the steps without so moving the lever 20 21, connected to the valve, as to put the brakes on, while to hold the brakes on a retainingpawl 30 is freely pivoted at 31 to the brakeoperating lever 20 21 in suchwise as to drop into engagement with a stop 32, fixed on the bracket 10, when the lever is moved as bethe brake-operating lever 20 21 and enable,

the brakes to be taken ofi'.

The steps may in some cases be locked in their out of the way position and unlocked therefrom from the inside of the car. Fig. 11 shows such an arrangement, in which the locking-lever 5 is adapted when the steps are in their out-of-the-way position to be actuated through suitable connections, such as a chain 33, and a suitably-supported rotary chain-wheel 3 1, havingatapered square hole in its boss adapted to be engaged by the correspondinglyshaped inner end of the axle6when the steps are in their out-of-the-way position from a hand-lever 35, located within the car and to which the two ends of the chain 33 are connected, so that the steps may be thereby locked and unlocked, and may be then moved, as by pulling the pivoted hand-rail t of the steps in the desired direction.
