To. a lhvizo m it may m Be it known that I, Josue Bonmsoiv, a citizen of the United'States, and a resident of the city ot'New York, State of New Jl-ork, have iinvented certain new and useful 1m; pi'oveinents in Automatic Tlalhelfipe Con,-

' necters, of which the following isaspecifir i y the air and steam pipes between railway.v

tion. 7,

p .f h'Iyinvention relates toxautoniatic[train pipe connectors, for autoniatlcallycoupling cars, though it maybe used for. effecting such coupling between electrically hauled cars; 'An object of rny invention is to improve the coupling head ofgsu ch con necters,

and'niore especially to simplify the conof c'onstructionandinterchangeability; 1T0- struction of such heads whereby the. cost of manufacture may bematerially reduced, and

uniformity of" construction in; largejquan tities readily attained. "In an equipn ento f this character efficient interchan e between mating heads, made at sundry andyari us 1 tin1es, mustlbe certain and dependable. 1* or that reason it is essential that theldesign of the head be such as to readily assure uniform construction. ,To' attain this object is the purpose of my invention, and to'that end I provide' what is known as a butt faceflcou pling. head having: separately constructed guiding prongs; Heretotore, suchuprongs have been constructed integrally vwitlrtl e base of the coupling head. Such design pro; duces a construction diflicult to successful cast, and requiring,a'fllargelamountof \j; pensive machine work to attainuniformlty remove these obstacles 1 construct Lngyv proved coupl ng head ofthree-p,1eces,,con sisting of a palrof independent w ngs and a base. This construction greatly facilitates the economic and, unrt'orrn manufacture of the coupling head and produces a rugged,

. and durable construction-offering the maxi;

ments, combinations, and constructions her muni service'efiiciency and dependableirr terchangeability. v y 7 v My improvement consists of the arrange-.
