PAUL WINSOR, OF WESTON, MASSACHUSETTS.
PORTABLE AUTOIVIATIC STOP MECHANISM FOR CARS.
Specification of Letters Patent.
Patented Feb. 4, 1908.
Application filed August ZI. 1907. Serial 110.389.475.
To all whom it may concern.'
Be it known that I, PAUL IVINsoR, a citi- Zen of the United States, residing in "Weston, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Portable Automatic Stop Mechanism for Cars, of which the following. description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to a portable automatic stop mechanism for use on railway cars and locomotives, employed on railways operating with steam, electricity, or other motive power.
The invention has for its object to provide a portable device, which is capable of being applied to either end of a ear and operatively connected with the air brake system, so that said device when engaged by one of a series of actuating devices located along the tracks, will operate the air brake system to set the brakes and stop the car.
In accordance with this invention I eniploy a portable device having connected with it a standard brake or other coupling, whereby the device can be coupled to the train pipe of the air brake system by means of a coupling attached thereto, or to the regular coupling usually found at the ends of all locomotives, cars or trains.
Provision is made for supporting the device on the locomotive or car at either end in a position to be engaged by an actuating de vice located along the track.
These and other features of this invention will be pointed out in the claims at the end of this specification.
Figure 1 is a side elevation of a portion of a locomotive provided with an automatic stop mechanism embodying this invention. Fig. 2, a front elevation of the locomotive shown in Fig. 1. Fig. 3, an enlarged vertical section of the stop mechanism shown in Fig. 1. Figs. 4 and 5, modifications to be referred to, and Figs. 6, 7 and S, details to be referred to.
In Figs. 1 and 2 I have represented one form of portable automatic stop mechanism applied to a locomotive e. The portable stop mechanism shown in Figs. 1, 2 and 3, consists of a chambered body b, to which is secured as by cement c or otherwise, a glass tube d, which is closed at its upper end and open at its lower end to communicate with the chambered body l), which is provided as shown with a nipple e, to which is secured air-tight, one end of a flexible pipe or hose f, having attached to its opposite end a coupler g of any suitable construction, such as now employed on railway cars and which coperates with a coupling 7L attached to or connected witlrtlie flexible pipe or hose c' usually found at the ends of locomotives and cars equipped with the well-known air brake system.
The chambered body l) provided with the frangible portion or glass tube d and with the hose section f having the coupler g constitutes a portable automatic stop mechanism, which is detachably secured to the car orlocomotive so that it can be placed at either end thereof according to the direction in which the car or locomotive is running.
In Figs. 1, 2 and 3, I have illustrated one way of attaching the portable stop mechanism to the locomotive or car a, which consists of a hollow extension 10 projecting from the chambered body l) and adapted to lit over a holder, shown as a post or upright 12 attached to the pilot 13 of the locomotive. The extension 10 may be secured to the post 12 by a locking pin 14 carried by a boss 15 on the extension and adapted to be forced into a groove 1G in the post lor upright 12 by a spring 17 acting against a collar 1S on the said pin, which is provided with a suitable handle 19, by means of which, said pin may be disengaged from the post 12.
WVhen the stop mechanism is placed in its operative position on the locomotive or car and coupled to the air brake system, it forms part of the latter and the air in said system may be released to apply the brakes, by'
venting the air brake system through the portable stop mechanism, which is accomplished as herein represented by breaking the glass tube (l. The breaking of the tube d may be accomplished by an actuating device, which is projected into the path of movement of the portable stop mechanism. In the present instance, I have represented the actuating device as a horizontal arm 20 (see FiO. 2) attached to a vertical rod 21, which is Iocated alongside of the track and may be suitably connected to the usual signal mechanism (not shown), so as to be turned into may be an ordinary passenger car, such asv used on steam roads and the portable automatic stop mechanism is detachably secured to the platform 22 thereof. In this instance, the chambered body b is shown as a nipple (see Fig. 7 on the end of an arm or bracket 23, which is provided with a lug or finger 24 (see Fig. 6) to engage a socketed holder 25 (see Fig. 8) bolted or otherwise fastened to the platform of the car.
In Fig. 5, the holder 25 is shown as secured to the truck 26 of the car and the latter may be sup osed to be an electrically operated car. t will be understood, that the car may be an ordinary freight car and the portable stop mechanism may be attached to the car body, its truck, or other part, and arranged so as to be engaged by the actuating device.
I have herein represented the chambered body as provided with a frangible portion,
which is designed to be broken by contact attached to said chambered body, and a with the actuating device, but I do not desire to limit my invention in this respect, as the chambered body may be provided with a valve or stop cock, Whose stem is adapted to be struck by the actuating device so as to open the valve and,vent the chambered body.
It will be observed that the automatic stop mechanism is portable and capable of being readily attached to either end of the car according to the direction in which the latter is traveling, and is also capable of being connected with the air brake system at either end ofthe car, train, or locomotive. Furthermore, it will be observed that but a single stop device is required for each train or car, and that the transfer to either end of the car can be effected in a substantially short time. So also, it will be observed that the portable Stop mechanism is simple, ineX- pensive and can be adopted by any railway system at a minimum cost, as a single device for each car or train of cars, is 'sucient By the term car7 as used in the claim, I desire to be understood as including a single` car, either freight or passenger, a locomotive, or a train of cars.
If desired, the car coupler head may constitute the support or holder for the portable automatic stop, in which case the extension 10 may be inserted in the pin-hole in saidy cou ler head.
