This invention relates to car couplers and its general object is to provide a coupler for the air and steam lines of cars, that couples automatically and simultaneously with the operation of the usual coupling now genera ly employed for coupling the cars themselves together, and the steam and air 'couplings are uncoupled accordingly with the uncoupling of the-car couplings, therefore an attendant does not have to endanger himself by stepping between the cars for this purpose. 7

A further object of the invention is to provide a coupling for the steam and air pipes of cars, that is capable of forming a leak proof connection between the point of juncture of-the air lines. a 1 v Another object of the invention isto pro 7 vide a coupling device of the character set forth,that is simple'in construction, inexpensive to manufacture and install and :efficient in operation and service.

This invention also consists in certain other features of construction and in the 2 combination and arrangement ofjthe several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the 'several views, and in which:

Figure 5 is a vertical sectional view taken Figure 4 is a similar View in coupled posi through the coupling in operative position. Figure 6 is a face view of one of my coupling devices. I

Figure 7 is a sectional view taken approximatelyon line 77 of Figure 1.

Referring to the drawings in detail, the letters A and indicate the confronting ends of a pair of cars which are provided with the usual coupling members C'for' coupling the cars themselves together. These coupling members are retained in position through the instrumentality of a pin as shown, and this pin'is operated by a hand operating member D havingoneend connected with the pin, while its opposite end terminates in a handle E extending laterally of the cars as shown. The hand operated member is formed with a horizontal portion F j ournaled at its ends'to the car. This horizontal portion F has fixed thereto a weighted lever G so as to normally'retain the pin in v operative position. v

Mounted for slida'ble'movement in suitable cross members secured to the car are draw bars 1' having collars 2 secured thereto for the purpose ofacting as a stop for one of the ends of coil springs 3 while the opposite ends of said springs are disposed in contacting engagement with one of the cross members as best shown in Figure 2. By this construction, it will be apparent that the draw bars are normally retained in their outermost position through the medium of the coil springs so that the draw barsare under constant tension. g

Theouter ends of the draw bars terminate in forks4 which pivotally receive the shanks 5 of heads 6. The heads are mounted for movement in a horizontal plane and to limit this movementthere is provided leaf springs 8 having'one of theirv ends fixed upon opposite sides of the forks while the opposite or free ends are disposed in'cont-acting engagement with the opposite sides of the heads. The heads 6-are formed with reas clearly shown in Figure 5.

Formed with the outer ends of the arms are the self coupling shoes of my. device and these shoes are formed in a manner to cooperate with each other as shown in Figure 5.

The shoes each include spaced parallel members 12 and 13 which terminate't in rounded outer ends having secured thereln a pin 14 traversing the members for a purpose which will be, presently apparent. Formed with the member 12 whichis' rela tively narrower than the member 13 is a jaw 15 disposed in spaced relation with respect to the member 13 and has formed therein a bore 16 having its upper end extending at right angles so as to discharge on the inner side of the j aw 15. The discharge end of the bore has arranged therein a rubber gasket 17 having annular flanges providing a channel for. the purpose of receiving the annular edges or the bore which is flanged for that purpose which is clearly shown in Figure 7 of the drawings. The'lower end of the bore 16 extends through the bottom of the jaw which is provided with a collar 18 havin fixedly secured thereto the adjacent end 0? the pipe line '19. r r V V The jaw 15 of one shoe is disposed on one side thereof, while the jaw of the other shoe is disposed on the other, and the shoes of each jaw are similar in construction and have formed on their outer ends hooks 20 to be received by the pins 14 when the shoes are arranged in cooperative associationas shown in Figure 5. c

When in such cooperation, the inner sides of the jaws are disposed in contacting engagement with the rubber gaskets of the bores thereof disposed accordingly jsofas to provide a leak proof connection between the pipe lines 19 and 21. v V

The pipe lines 19 and 21 are provided for conveying steam and the pipe lines 22 and 23 convey air. are likewise disposed in communication through the medium of my'coupling and for this purpose the shoes are provided with substantially L-shaped members 24 having bores 25 formed therein with the pipes 22 and 23 in communication therewith. The inner ends of the bores are disposed laterally to the inner side of the 'L-shape members 24:

which are provided with recesses 26 to recelve the rounded heads of said members 24 as shown when theshoes are 1n cooperative 1 position. The confronting ends of the bores The pipe lines 22 and 23.

are flanged to accommodate rubber gaskets 27 of the same character as clearly shown in Figure 7 so as to provide a leak proof connection when the gaskets 27 are disposed in contacting engagement as shown in Figure 5.

In order to secure the shoes in cooperative position asshown in Figure 5, I provide means for coupling the heads together and securing them accordingly and this means includes the housing member 28 on each head and these housing members are formed with horizontal walls having pivotally secured therebetween jaws 29 arranged for move- The jaws 29 are enlarged as at 30 at one end to provide a counter-balancing mean's therefor, while the I opposite ends terminate in hook members 31 ment in a horizontal plane.

having formed therein hook shaped recesses 32.91? .a sizento accommodate the large port1ons'of the'hook member as shown, Figure 4, as the recesses receive the large portions when the coupling is disposed inoperative position in the manner as shown inFigure 4.

The ,pivot pins of the jaws 29 pass throughthe large portions ofthe hook members and spaced parallel ears 33 arranged in cooperating pairs as best shown in Figure 3. By this construction, it will be apparent that when the jaws 29 come together that the large portions of the hook members will clude a lever 34 terminating at one end .105

in an eye 35 secured to the head by-a pin for pivotal movement thereon as will be apparent. The opposite end of the lever 34 is directed upwardlyat an inclination as at 36 and terminates in an end bent at right 1-10 angles to the upwardly disposed portion as best shown in Figure 2. The latching means also includes a substantially right angle shaped lever 37 having one of its ends se-' cured to the eye 35 while its opposite end terminates in an eye 36 for the purpose of accommodating one of the end links of a chain 39 which is secured thereto and the other end of the chain is fixed in an eye 40 of a link 41 which is secured to the weight of the weighted lever G. The latching means of each of the heads is provided with a coil spring 42 for urging the right angle bent ends 43 of the levers 3a in a downward direction so that these ends of the levers 3 may retain the jaws 29 in either an operative or inoperative position. as

shown in Figures 2 and 1 respectively. I

In other words, when the jaws 29 are disposed in inoperative position, the right angle small hook portions of the 1 bent ends of the levers 34 normally rest upon the top of the enlarged portion 30 of the gether in a leak-proof'manner, and the cou pling members accomplishing this purpose are operated to coupling position when the cars come together and are uncoupled simultaneously with the uncoupling of the car coupling means. i

The outer edges of the confronting sides of the jaws 15 are slightly beveled as at 44 as shown in Figure 3 so as to insure proper cooperation between the jaws when the latter come together. The shoes are provided with recesses 45 disposed between the jaws 15 and the members 13, and these recesses 45 have rounded inner walls which cooperate with the rounded upper sides of the jaws 15 to cause the jaws to be moved downwardly when the shoes come together so as to fix the hooks 20 of the jaws 15 about the pins 14. The jaws 15 are not movable by themselves but the shoes in their entire ties move on the pivots of the arms 10 as will be apparent upon inspection of Figure 5.

It is thought from the foregoing description-that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the sev-' eral parts, provided that such changes fall within the scope of the appended claim.

What I claim is:

In combination with a coupling for rail-' vay cars, a combined steam and air coupling comprising spring pressed draw bars, spring pressed heads pivotally secured to said draw bars and having recesses formed therein, means for retarding the pivotal movement of said heads, arms pivotally secured in said recesses, ears formed with said shoes, spaced members included in each shoe with the jaws between the same, pins carried by said shoes and traversing one member and its jaw, hooks formed with said jaw and being adapted to be received by said pins for securing the shoes together, L- shaped members formed with said shoes and together with said jaws being provided with bores, said L-shapedmembersand jaws cooperating for disposing the bores thereof in communication to provide a leak proof connection therebetween, air and steam pipe lines in communication with said bores, rounded heads formed with said L-shaped members which are recessed to accommodate the heads of each other, means for coupling the first mentioned heads together, latching means for said coupling means and being operable upon operation of the car coupling.

In testimony whereof I afiix my signature.

JOSEPH G. TURRIN.
