ADJUSTMENT FOR TEBMINALS WITHIN HEADS To all whom t may 10W/06m;

it known`v that I, EDWAnnA. ROBINSON, a citizen of the United States, re-sidinget "lontreal, Province of Quebec, Can-ada, have 4'iiventedac ertain new and useful Adjustfient for Terminals Within Connecter leads, of which the following is a specificanon. My invention relates to train connecters intended for automatic operation to join air or steam,pipes. of adjacent cars.

The4 purpose of my inventionis to provide quick,l ready and reliable means Jfor determining thecxtent of normal projectionof train pipe yterminals beyond the connecter head by which they are carried.

A further purpose is toadjust the total extent. of projection of a train pipe terminal byrboltsor lstuds extending parallel to the axesof Athe train pipe terminals and surrounded individually, or collectively, for each terminal by springs with springs about the terminals inside the bolts in the latter case.

.Furtlienpurposes will appearin the specification an in the claims.

I T.prefer to illustrate my invention by two slightly variantforms only, selectin forms which arepractical, efficient and re atively inexpensi\-"e, and which at the same time Well illustrate the principles of my invention.

Figure 1 is a side elevation of a connecter headand its supporting mechanism to which my v,invention is applied.

' Figure 2 is a. verticahlongitudinal section throufrhhe head-considered as detached from` its supportsshowing one of the forms of my invention.

Figure 3 is asection of,Fignre 2 taken upon line 3 3.

Eigure 4 is a fragmentary longitudinal section lshowing the other form.

No. 412,647, in which the head iis carried by a yoke 6 Whose feet 7, 7

A'yariety of forms or springs is permissiblehconsistent with the placing of the bolts or studs and fallin generally into `the classes of a) individual to the. bolts 0r. Studs,` afnd @5). Surrounding *2he4 terminals- 'fThe terminals pass through bores 21 Within 'internaily extending anges 22 and are enlarged at their outer ends :11223 to fit counter-bores 24:. The enlargements afford seats for the gaskets 25, 25', Yanchorages for the bolts or studs 2G and ab-utments for the outer `ends of. spiral springs-2, surrounding the individual'l bolts in Figures 2 and B or 27, 28 surrounding the terminals outside and ins'de the1bol`t's, respectively iniigure 4.

he springs press at their rear Aends against the `anges 22 andthe bolts or studs pass `throng thesel annular inwardly directP edjanges 22 and reoeivei lock nuts 29 which bear a. ainst the rear faces of the flanges.

'The eads yare .annular-ly recessedI at 30 to protect the nuts andbolts from accidental interference.

The annular recesses 30 Iaffi'ord access for arsocket `Wrench by which the nuts may be adjusted. f' The askets'25 and 25 are the usual air pipe an steam gaskets, respectively and the steam terminal 'gaskets are retained by the spring 3l as usual. Within the terminals I place ribs 32 for engagement by a plug wrench so as to conveniently screw the terminals into the fittings 33, -l for connections which may be l/Vestinghouse and Gold couplers 35 and 36.

My invention is equally applicable to heads intended to carry but a single terminal, as would more usually be the case in freight service and to heads intended to carry two or three terminals as ordinarily required in passenger service.

In assemblage I will consider separately the conditions if the fittings 33, 3ft be free to be rotated for application after the rest of the structure has been assembled and while the terminal is being steadied in its position by a socket wrench.

In that event the studs are first screwed into the enlargements 23 and the springs are put in position within the spaces 1S. The terminals, with the studs attached, but without the look nuts, and with the springs eitherabout the individual studs or about the terminals are put in position so as to pass the studs through the openings in flanges 22. The lock nuts 28 are then set and the fittings are subsequently attached. This is the preferred form of assemblage since the capability of placing the fittings 33, 3st after the head is otherwise assembled, carries with it the capability of disconnection ofthe fittings from the terminals without disasseniblage of the rest of the head structure.

Vdiere the fittings are not free to rotate, the springs are inserted within the head openings and the terminals are placed and screwed into the fittings before the studs are placed within the enlargements 23. The studs are first passed through the flanges 22 and through or between the springs and are afterward screwed into the enlargements, after which the nuts 29 are seated by socket or Spanner wrench.

In either event the extent of normal projection of the terminal beyond the head may be accurately determined and may subsequently be adjusted with great nicety by seating the lock nuts at appropriate positions upon the studs.

It will be evident that the main reason for placing the flange 22 within the head instead of at the outer edge of the head is to give room for the nuts within the head and to avoid interference with the adjustment and breakage of the threaded stems at the rear of the head protecting also from accidental displacement of these nuts. Where these advantages of protection do not appeal, there is an obvious advantage in placingthe flange 22 far enough back for the nuts to be accessible by the use of an ordin'ary wrench.

" lVhere theisprings encircle the studs or bolts more springs are required butthere is some advantage from the increased number of springs, in that any one of them is effective to give partial support and pressure in case of breakage of the others.

It will be obvious that Vthe disclosure of my invention will suggest to those skilled in the art other forms by which all or a part of the benefits or" my `invention may Vbe secured, and it is my purpose to include herein all such as come within the reasonable spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. In an automatic train pipe connecter, a connecter head having an opening therethrough counterbored at the forward end and providing an inwardly extending flange in the rear thereof, a train pipe terminal passing through thev opening and enlarged at the forward end to slide within the countei-bore, studs secured and extending through the studs affording adjustment of maximum terminal extension and springs about the terminal within the counterbore bearing against the enlargement and flange. l
