. CONNECTER-HEAD SUPPRT.

Application iled December 17, i921. Serial No. 522,983.

The purpose of my invention is to provide.

separate spring support for thev upper and lower'portions of the head.

A further purpose is to give each separate spring support independent rockingconnec'- tion with the head. A

A further purpose is to .provide adjustment of theplane at the head by separate 20 projection or retraction of the top and of the bottom of the head.

A further purpose is to provide universal joints. at top and bottom of lthe head that the rocking of the head during service may 25. not vbreak contact between parts of the head and the adjoining head.

A further purpose is to reduce shock and strain on the head by dividing these shocks I and strains at each spring support between two springs and by partially relieving strains at each of these supports by a rocking-and slidable joint. I

Further purposes will` appear in the specification and in the claims.

I'have preferred to illustrate my invention by one form only, vselecting the `form "with a view to its value in illustrationof the. principles of my invention.

Figure 1 is side elevation of a connecter embodying my invention.

Figure 2 1s a broken rear end elevation of the structure seen in Figure 1, showing the connection of the springs with the bracket.

Figur isa broken top plan view-ofthe structureseen in` Figure 1.

providing a rocking or rolling and sliding joint between each spring support and the head.

Describing the structure shown in Figur'es 1 to 4, by -way of illustration and not in limitation The bracket 10, in rigid connection with .the car, carries

spring supporting clamps

11 and 12. These clamps are duplicates and are split at 13 to permit insertion of the

springs

14 and 15. They `are threaded to correspond approximately with the spirals of the springs and clamp by reason of vthe fricy tion against the exteriors of the springs. I'

recognize that .the character of the clamp here is not material provided it be some device whereby the spring may be rigidly held at one or other end. The clamp is-tightened to X the spring in position. Adjustment of the spring is permitted by changing l the length by the distance between adjoining turns, threading it longitudinall through the clamp with the clamp loosene The two springs 14:` and 15 extend forwardlv and support two head carriers 16 'and As shown in Figure 3 these head carriers have similar reversely directed

arms

18 and 19 which branch at 20 into forwardly projectedy substantially parallel yokes having

opposite sides

21, 22 respectivelyconnected by

terminals

23, 24. l'lhese terminals mate and cooperate with reversely

shaped surfaces

25, 26 upon the rear of the head 27 to form sliding, rocking or universal joints between the carriers and the heads. These cooperating joint members may be of such wedge-shaped, conical or curved section upon their meeting faces as best suits the particular purpose in mind.v Thus in Figure 1 a V-shaped wedge is shown, whic i., however, may be conical where sliding and retraction from tilting in any direction is contemplated. Vertical or horizontal sliding or tilting movements alone would be useful where, as permissible under my invention, the

arms

18 and 19 connect with a single clamp'such as 16 or 17 united with a bracket by a single spring, or with any other construction in which the

arms

18 and 19 are rigid with each other.

Where various tilting and rocking move. ments are to be accommodated to give as great iiexibility as possible with some sliding of the parts, spherical or cylindrical contours also can be used, as in Figure 5, for the two connections from

arms

18 and 19 to the head. The forms shown in Figures 1 and 5 are both better suited to and V'giveniuch better results withrelative movement of the

arms

19 and 20, and particularly with independent spring support of these arms than where vthe arms are rigid with each other, as would'be the case if united to a single clamp limiting the advantage to sliding movement or to sliding and tilting with respect to the plane unitinthe joints.

ither, of the parts of the pair may carry the projection and the other the recess, and the space for the joint'may be secured b different formations of the head or by si e extension of the head at 28', 29 (Figure 6), if desired, instead of by the end extensions of 28 and 29 shown.

In Figures 1 and 5 the head 30 is 'intended to be shown generically. It carries any suitable ears 31 and tube and gasket construction forjuniting the several Huid conduits of one car with those of another. These tubes have shown generically at 32 as suitable for passenger traic. If used for `freight. traic there will probably be, but one or two yot these fluid conduits.

The wedge I.'iorm of universal joint is best illustrated in Figures 3 and 4 where the

head extension

28 or 29 and

carrier terminals

23 and 24 are resiliently held together by the bolt 33 and spring 34. The bolt lits loosely through the terminal .and passes through the preferably conical spring 34 to a combined nut and washer 36 thus pressing together the two parts of the joint. The spring34 fits in a recess 37 in the ter-V minal to maintain this end in place. Relative tilting or sliding between the parts of the 'oint `1s provided for by a temporary yiel in in the spring and by the loose tit of the elt withinthe terminal.

Where one direction only of yield is de- Sired-vertical in Figure 1, the V-shaped Y wedges will serve Ias they will slide for actual vertical movement between them' and will rock about the edges of the terminal in response to tilting strains in either vertical or horizontal planes. However the retrective operation of the wed acts across the wedge only. appreciatet at with very much less advantage these members may be fiat, and not wedge shped, spherical or con-` position ywhen de- Y brought about by above. Continuous jars of service will aid inovercomin friction between the 'flat surfaces and wil automatically center the parts to normal position.

With tapered, conical, or spherical forms alike, the surfaces defining the side walls of the recess become wedges, such asy 38 and 39 (Figure 4), on which the matin side walls of the projection will slide tofrelieve any serious lateral strain upon the head. This will cause the wedge surfaces of the projection, such as 40 or 41 with the construction seen in Figure 4, or any art of the conical or spherical surface, un er like circumstances, to climb the wedge face of the recess permitting shifting of the head as well as separating the parts longitudinally of the bolt.

lfVhen the parts are in normal position, tilting can take place between the

individual terminals

23, 24 and the head about the limit-- ing edges of the terminals. Where these limiting edges' are rectangular, as represented by the edges 42 and 43 in Figure 4 and by the edges parallel to them,`ie tendency will be to tilt .about one or other of these edges.

Though circular edges within the plane of the edges 42 and 43\ wouldgive ready tilting without regard to the directionof strain, I prefer the rectangular shape for these terminals because Athe strains chieiiy to be accommodated are in vertical and horizontal planes.

It will be evident that tilting of the -te'rminals in the direction of any given vertical or side movement of the head, such as tilting about the upper edges of the terminals after upward sliding vertical mo-vement of the head, takes place about a shorter radius than when the parts are in the position shown in Figure 1. This is true because .that wedgeelement, parallel to the apex of the wedge, passing through some such point as 41 would then be restinr against the upper limiting the edge 44 o thewedge seat and the lines ofengagement both in the head and in the terminal would lie closer to the bolt than with the position ofthe parts as shown in Figure 1.

The split clamps 12 of the

carriers

16 and 17 are like the clamps at 11 and 12. In Figure 1 the/bolt lugs of 11 and 12 are shown horizontal while those of 16 and 17 are shown vertical. Other means than threaded split clamps might be used, and other forms of resilient support for the carriers can be Aused to provide for independence of movement.

In operation, the ears of the head interit with corresponding ears on the head o f a connecter upon an adjoining car, making gasketed union between the Huid conduits,

lliU

ment with its fellow- Strains due to ver-` tical andlateral lack of alignment are relieved partially by the joints between the heads and the -carriers where both rocking and sliding movements can take place.

In the form shown in Figures 5 and 6 the two

carriers

16 and 17 are rigid with

arms

18 and 19 respectively but these arms are not divided as in the precedingv form. At their ends the arms support laterally 'eX- tending

terminals

23 and 24 which coact with

extensions

28 and 29 respectively at the sides of the heads.

It will be noted from the illustration in Figures 5 that the engaging surfaces of the being seen in curved line 45, as distingulshed4 members are spherical, an arc of the s here from the triangular engagement shown in Figure l. Evidently various forms of construction could be made to carry out the purpose here as in other parts of the invention. Where but one carrier is to be used to support both arms of this figure the surfaces would be wedges or cylinders.

From my description various forms of the invention will be obvious to those skilled in the art, to suit particular installations or the preference of the designer and; it is my purpose to includel herein all such come within the reasonable spirit and scope of my invention.
