Application filed July 6, 1917i SerialNo. 178,981.
To all 'whom imag conce/Mi;
Be it known that I, JAMES L. KEITH, a citizen of the United States, residing `at St. Louis, State of l\'lissouri, have invented cer` tain new an'd useful Improvements in Railroad-Train Stops; and I do hereby declare the following,1 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.
This invention relates to improvements in a railroad train stop and has for one of its objects the provision of a device of this character whereby trains entering upon the same block will be automatically stopped.
Another object of this invention is the provision of means whereby the train crew of one train can communicate with the other train crew. on the other train when in the same block.
A further object ,of this invention is the provision of an electric motor for automatically applying the air brakes of the train when entering` the block with another train.
A further object of this invention is the `provision of means for automatically stopping the motor after applying the air brakes.
A still further object of this invention is the provision of a railroad train stop of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.
llVith these and other objects in view as will become more apparent as the `description proceeds, the invention consists in certain novel features of construction, combination ,and arrangement `of parts as will be hereinafter more fully described and claimed.
For a complete understanding `of my invention, reference is to be had to the follow ing description and accompanying' drawings, in which Y d Figure 1 is a transverse sectional view of a `locomotive illustrating my invention applied thereto,
Fig. 2 is a diagrammaticalview of the wiring` diagram of my invention,
Fig. 3 is a vertical sectional view of one of the contact arms carried by the locomotive, i t g Fig. 4 is a fragmentary perspective view of the communieating` ends of two blocks,
Fig'. 5 is an end elevation of the hanger, and
Fig. 6 is a plan view of a railroad track havinga switch.
Fig. 7 is a fragmentar plan view drawn on an enlarged scale of the switch. i
Fig. `8 is a fragmentary side elevation illustrating the ends of theblocks.
Referring in detail to the drawings, the numeral l indicates as an entirety a locomotive which is provided with the usual air brake system 2 controlled by a valve 3. Branch pipes 4 arelconnected with the brake system 2 Awhich has a controlling valve 6 that is provided with a handle 7. han dle i' has pivotally connected thereto a bar 8 which meshes with a pinion 9` The pinion 9 is formed upon an enlarged gear 10. The enlarged gear-10 is journaled within the locomotive 1 in any desired manner and meshes with a pinion 11 formed upon a gear 12. The `gear 12 is journaled in the locomotive in any well known manner and meshes with a pinion 13 of an electric motor 14 located within the cab of the locomotive. t
Wires or rods .34
are located along sash aide et the rails of a track as illustrated in The rods 16 have connectedV Fig. 4. Supports 35 are secured to the ties of the track and support one of the ends of the wires or rods 34 of one block, while the supports 36 support the ends of the rods or wires 37 of another block. Auxiliary supports 35 support the rods between the supports 35 and 36. 'v
l/Vhen a block is occupied by a train, upon a second train entering the same block travelingv in the same direction, an electric circuit will be completed to the motors 14 upon each of the trains owing to the contact wheels 20 traveling upon the wires or rods 34. The motors are then started in motion which causes the rack bars 8 of both trains to move in the ldirection of the motors operating ther valves 6 to apply the air brakes thus stopping both of the trains. An arm y38 is carried by the rack bar 8 and as the same moves rearwardly during the operation of the motor, it engages the conk tact arm 28, disengaging the same from the contact 31, thus breaking the electric circuit tothe motor. f
K My invention is adapted for use on double track systems or where the trains travel over the tracks in the same direction. To prevent the battery ol one train trom working in opposition to the battery of another train when said trains are in the same block, the train despatcher when sending the various trains out on their runs gives orders to have the positive and negative poles of the batteries so connected t0 their circuits of the various trains that the battery of a following train will not work in opposition to the battery in the train in ahead or the first train.
When the trains have entered upon the same block the crews of the trains may communicate with each other by way of the telephone 25 and after the electric current has been broken to the motors, the telephone 25 of each train will still remain in opera- 'tion thus permitting the crews to decide upon their further'procedure.
Ratchet wheels 45 are journaled in the hangers 15 and have formed thereon a plurality or' projecting arms 46. Spring actuated dogs 47 are carried by thc hangers and normally engage the ratchet wheels 45. Resilient arms 48 are secured to the arms 16 and are adapted to move into engagement with the ratchet wheels when said arms are moved upwardly against the tension of the springs 17, as for instance, when the train is leaving one block as illustrated at A, the rods 16 are moved upwardly by the supports 35 and by so doing rotates the ratchet wheels to position one of the arms thereon to support the rods 16 in an elevated position by engaging the lugs 50 upon the rods 16. The rods 16 are supported in this position until the contact wheels 20 engage the supports 36 which causes the ratchet wheels 45 to be again moved upwardly owing to the supports 36 being higher than the supports 35 which disengaging the arms 46 from engagement with the lugs 50 which permit the arms 16 to move downwardly under the infiuence of the springs 17 permitting the contact wheels 2O to follow the rods or wires 37.
The heretofore described construction is employed for preventing the wheels Q0 ot the spring pressed rods 16 from being toreed to a plane below the rods or wires of said blocks at their ends when the train is passing from one block to another.
While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes m construction, combination and arrangement. of parts may be made without departing from the spirit and scope of the invention, as claimed.
What I claim is:
A railroad train stop including an' engine having an electrical brake operating means and an open electric circuit associated therewith, spring pressed members connected to the engine and to the circuit, block forming members engaged by said spring pressed members and having their ends elevated` and ratchet means affected by the elevated ends for holding the spring pressed members elevated when the engine passes from one block to another.
In testimony whereof l afllix my signature in presence of two witnesses.
