. AUTOMATIIZC AIR-HOSE COUPLING;

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed April 7, 1908. Serial No. 425,722,

To all whom it may concern:

Be it known that I, NELSON ToY, a citizen I of the United States, residing at Weir city, in the county of Cherokee and State of Kansas, have invented a new and useful Automatic Air-Hose Coupler, of which the following is a specification.

This invention relates to automatic train pipe couplers andhas for its object to provide astrong, durable and thoroughly efficient device of this character for automatically connecting the train pipes of adjacent cars when said cars are coupled.

A further object of the invention is to provide a couplinghead having means for attachment to the usual hose cou ling so that the device may be used, on freig t or passenger cars without the necessity of making any change in the construction of either the car or train pipe.

A further object is to provide improved means for guiding the coupling-heads as the cars come together and means for yieldably su porting said heads in operative position be ow the platform of the cars.

A further object is to provide means car ried by the coupling heads for connecting t he electric conductors of adjacent cars so that telegra hic or telephonic communication may be estalilished between the several carsof the tram.- t

A still further object of the invention is generally to improve this elass of devices so as to increase their utility, durability and efficiency. I

Further objects and advantages will appear in the following description, it being understood thatvarious ohanges in form, proportions and minor details of construction may be resorted to within the scope .of the ap ended claims. i

n the accompanying drawings forming a i part of this specification: Figure 1 is a slde .elevation'of an automatic train pipecoupler constructed 1n accordance with my lIlVeHtlOIl showing the same in operative or cou led po- 'sition. Fig. 2 is an enlarged side e evation showing the heads in position to be coupled. Fig. 3 is a plan view of one of the coupling heads. Fig. 4 is a vertical sectional view taken on the line 4 4 of Fig. 3. Fig. 5 isa transverse sectional view taken on the line 55 of Fig.3.

Similar numerals of reference Indicate cor responding parts in all of the figures of the drawings.

The improved train pipe coupling forming the subject matter of the present invention may be used on freight cars, passen er cars and other rail-way rolling stock and y way of illustration is shown attached to a freight car of the ordinary construction in which 5 designates the platform of the car and 6 the draft head or coupling, preferably of the J annoy t pr and adapted to engage the mating coup ing 7 on the adjacent car, as 'shown. As the couplings on both cars are similar in construction, a detailed description of one of said couplings will suffice. Depending from the draft coupling 6 at the reduced end thereof is an arm or bracket 8 to the free end of which is ri idly secured in any suitable manner one emf of a heav coiled springt), 'the opposite end of which is seated in a recessed extension 10 on the adjacent fluid pressure coupling head 11.

The

coupling head 11 is preferably rectangular in shape; as shown, and is provided with a centrally disposed opening 12 having a passage 13 communicating therewith and opening through the rear face of the coupling head. Threaded in the walls of the passage 13 is one of the members 14 of a hose coupling of the ordinary construction, said member being adapted to engage a mating member 15 secured to the free end of'the train pipe 16. I Extending laterally from the face of the coupling head 11 is a pyramidal shapedprojection 17 adapted to enter a correspondingly shaped recess 18 formed in the head of a mating coupling when said heads are united, there being a rubber gasket 19. surrounding the opening 12 so as to prevent leakage of fluid when the heads are coupled,

Attention is here called to the fact that the springs 9 support the coupling heads 11 in proper position beneath the

draft devices

6 and 7, saidsprings serving to receive the impact of the coupling heads and also serving to maintain the gaskets 19 in contact with each other and thus effectually prevent leakage of the operating fluid. It will also be noted that by making the couplings 14 and 15 of the ,usual type the train pipe of one car may be connected witli'the train pipe of a matin car when said mating car is not equippe with a coupling head constructed in accordance with. this invention.

As a means for establishing telegraphic and telephonic Communication between the several cars of a train, each head is provided with a socket having an insulating sleeve or bushing 20 threaded therein and pierced at one end by a metallic sleeve 21 to which is secured the adjacent terminal of the electric conductor 22, the latter being extended be' neath the car in the usual manner, as shown. Slidably mounted within the sleeve 20 is a contact pin 23 having a reduced extension 24 adapted to contact with the metallic sleeve 21 when the cars are coupled thereby to complete the circuit. Interposed between the rear end of the sleeve 20 and an annular collar on the contact pin 23 is a coiled spring 25 which serves to normally and yieldably support the free end of the contact pin in position to be engaged by the contact pin on the coupling head of a mating car. It will I thus be seen that when the cars are coupled the projection 17 on one of the coupling heads will enter the socket 18 in the coupling head of the adjacent car and in doing so will press the gaskets 19 in contact with each other so as to permit the flow of fiuid from the train pipe of one car to the train pipe of the next car.

As the cars are coupled the contact pin 23 on one coupling head will engage the contact pin on the mating head and automatically move the extensions 25 of both pins in engagement with the sleeves 21 so as to completethe circuit and permit telephonic com- -munciation between the several cars of the train. When the cars are uncoupled the spring 25 will automatically project the free ends of the contact pins 23 beyond the adj acent faces of the coupling heads and in position to a ain close the circuit when the cars are coup ed.

While it is preferred to form each coupling head with the passage 13 extending vertically from the opening 12 for connection with the coupling 14 it is obvious that the coupling may be connected directly with the opening 12 without departing from the spirit of the invention.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof isdeemed unnecessary.

Having thus described the invention what is claimed is:

1. The combination with a car including a train pipe, a bracket depending from the car, a spring having one end thereof secured to the bracket, a main coupling head secured to the opposite end of the spring and provided with an auxiliary coupling head for connection with the train pipe, and a pyramidal shaped projection carried by the main coupling head and adapted to enter a correspondingly shaped recess formed in an ad acent main coupling head when said heads are united.

2. The combination with a car including a train pipe, a bracket de endin from the car, a coupling head provi ed witi a fluid assage for connection with the train ipe, t iere bem a socket formed in the rear ace of the coup ing head, a coiled spring secured to the bracket and seated in said socket, and a projection extending laterally from the face of the cou lin head and adapted to enter a correspon ing y sha ed recess formed in a matiiigdcoupling hea -when said heads are coue p 3. The combination with a car including a train pipe, a bracket depending from the car, a coiled spring carried by the bracket, a main coupling head secured to the coiled spring and provided with a fluid passage opening through the rear of the coupling head, an auxiliary coupling head secured to the'rear face of the main coupling head at the mouth of said passage for engagement with the train i e, a gasket countersunk in the front face 0 t e main cou ling head and surrounding the walls of said passage, there being a recess piercing the main coupling head on one side of the gasket and having its walls converging towards the rear face of said head, and a pyramidal shaped projection disposed in spaced relation to the recess in said ead and adapted to enter the recess in a mating main coupling head when said couplin heads are brought together.

n testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

NELSON TOY.
