T 0 all whom it may concern:.

Be it known that I, Bonner M. Dixox. residing at Orange, in the county of Rssex and State of New Jersey, have invented certain new and useful Improvements in Couplings for Trnin-Pipes,of which the. f llowing is i: full, clear, and exact. thscrzption. such as will. enable others illcd' in the art to irhichit. appcrtnins to make and use the same.

This invention relates to car heating s tems and has for one o f its objet is to provide coupling means for the train pipes of separate curs characterized by increased siniplicity and etiiciency.

Another objectis to provide coupling means for train pipes for heating ystems of cars of such construction that the coupler may be readily removed from the hose scction {or renewal or replacement without in terfcring with the connection hetweon the hose section and the train pipe.

Another object is to provide 21 hose coupling for train pipes of car heating systems such that the some may he readily reversed and connected at either end to the trnin pipe or to the coupler.

Another object is to provide itltXllirarf; con net-ring :ncnns extending between the hose section of :1 coupling for train pipes and the fittings in either end thereof.

Other objects will be in part obvious and in par ointed out hereinafter.

'lln i (-ntion :t cordingl um features of construction, comli elements and arrangement or" mils n; w ll be exemplified in the de ice hero is shown one of the various possible enzhodi- 1 ments of my invention, Figure '1 is n 1-1)!"- showing the coupling means mmncctctl di rectly to the train pipe. Fig. 2 is an elevation partly in section of my improi'c'i train pipe coupling.

Similar reference characters ieivr to similar parts throughout the several views of the I airings.

Before entering into :2 description of the specific features of my invention and in order that the objects thereof may he more readily understood, it nun here he noted miter tit-scribed anal the scope of the ili ililthll-llli of which (till be indicated 1!). the following that in railway service the couplers of train pipes are subjected to exceedingly hard usage. As is often the case, owing to the pending means becomin detached, the

couplers are caused to drag thong the ground so Ti s-1i to Siriltc upon the ties. thereby renderin: them unfit for further use. I have, therefore, found it desirable to provide a cznzplin; for train pipes such that when the coupler becomes battered or otherwise dam- 6 aged. the some may be replaced without disturbing or removing in on way the connections between the coupling means and the train pipes or train pipe valves, to whichever of the said members the coupling may be attached. I have also found it desirable to provide a hose section having fittings'in ei her end thereof secured by clamps, said tugs being similar in all respects so that 93:. of being attached to either the train pipe :ncchotnsm or to the coupler. The above and 0 nor ob ects are achieved in constructions of to. nature of that hereiruitter described.

ott r-ring now to the drawings. A repre :fiiS n )flllWl}}' cur carrying the train pipe. 1. which forrns the feeding conduit for the several JE'illlLlltn oi the heating system. To either end of the train pipe 1 amonpling' B is adapted to be attached, as shown in Fig- 1. The coupling B forming one of a. pair of co-ncting members extending botivwn the train pipes of adjacent curs coma hose section =2, in either end of inserted a nipple raz' ed'with reportion t.- joininy 'iiers 7 and at their extremity are provided nrcznicd port ions 9. f hose section 4 are clamped securely irthc reduced pot-tin -s 3 of nipples :3 lv means of band chim s 10, the free ends of which one joined, in the present instance;

in, bolt-L it. 100

Nippics 5 are similar in all respects, and citht-r of said nipples capable of being threaded into the train pipe I or train valve 3. us the case may b the other of said nipnles being threaded into the coupler 12. as 10? -lcarly shown in Fig. 2. It will be understood. of course. that coupler 12 is one of a pair of co-ncting members joining the neighboring couplings of adjacent cars.

Each of nipples 5 is provided with lugs 1.10

eon )lin is readil reversible and co a- 75 s Nipples 9.0 e. at their intorn'wdnue portions, in this The respective 13. between which are secured, by means of bolts 14. auxiliary co-acting members designated by 16 and 17. which are also secured by bolts 11. between the free ends of band clamps 10. Auxiliary clamping memher 17 is provided with an opening 19 to receive the book 20 of the suspension chain 21 designated to be attached to the car body, as at 2:2. Chain 21 is adapted to suspend the coupling B from the car body and prevent the coupler from dragging along the ground and strikin r against the ties.

The method 0? use of my invention should be largely apparent from the drawlpingrtaken in connection with the above deseri ption. The coupling B is threaded into the train pipe or train pipe a-lve, as shown, and the coupler is threaded upon the nipple at the outer end of the coupler so that it may be readily detached. The clamps, to-

ether with the auxiliary connecting memhers, serve firmly to maintain the nipples in the ends of the hose section.

In order to provide against ambiguity in 25 certain of the termsemployed in this specification and claims, it may be here noted that by the term nipples is meant a fitting threaded or otherwise connected to two conduits to form a means of connection t'berebetween. By the term coupling is meant a hose section, fittings and coupler, --the whole forming one of a pair of connecting devices extending between the train pipes of adjacent -ars. By the term couplerj is" meant atnember secured in the outer end of the hose section; which is coupled to a similar member upon the coup ling of an adjacent car.

It will accordingly be seen that. I have 40 provided a coupling for train pipes of car connectors forms a convenient means for attachin the suspension chain to the coupling. t is. of course, obvious that. I am not limited to this precise employment of my invention, as the same is equally well adapted for use in other piping systems, such as. for

instance, airubralting systems and the like.

As many changes could be made in the above construction and many apparently widely difi'crent embodiments of my invention could be made without departing from the scope thereot'. I intend that all matter contained in the above description or shown in the accompanying drawings shall be. interpreted as illustrative and not in a limiting sense. I desire it al;-o to be under d that the language used in the fillowing claims is intended to cover all of the genera and spccitic features of the invention her! i'ndescribed and all statements of the .\=.'()2.H' of the invention. which. as a maiter of language, might be said to fall tliei'elii-twecn.

Having described my invention. what l claim as new and desire to secure by l.ct ters Patent. isz- 1. A coupling member for train plplS of railway cars comprising, in combination. a hose section having a nipple of a two-part coupler clamped in each end thereof. a complen'ientary part of a coupler threaded to one of said nipples. the other of said nip les being adapted to have a threaded ('()llli((f tion with the train pipe.

2. A coupling member for the train pipes of railway cars comprising a hose section having a nipple of a two-part coupler clamped in each end thereof. a compleim-ntar-y part of a coupler threaded to one of NIlLl nipples. said complementary part being adapted to reciprocally engage with a corresponding part carried by the opposite hose section, theother of said nipples having a threaded connection with the train pipe.

A coupling member for the train pipes of railway ears comprising. in combination. a hose section having located in either end thereof a nipple of a two-part coupler, a clamping member at either end of said hose, section adapted to clamp said nipple in po.-:ition therein. a connecting member srcurcd to each of said clamps and to said nipple, a complementary part of a coupler threaded to one of said nipples. said complementary part being adapted reciproally to engage. with a corresponding coupler part carried by the opposite hose sectiom'the other of said nipples having a threaded connection with the train pipe.

4:. A coupling member for train pipes of railway cars coinprisingfin combination. a hosesection having a nipple clamped in each end thereof. a coupler threadcdlv connected. to one of said nipples. the other of said nipples being thrcadedly connected with the train pipe. said nipples being similar and interchangeable.

In testimony whereof I allix my signature. in the presence of two witnesses.
