.ApplicationOctoberZB, 1945, Serial N05625J1'24 The present invention relates to diaphragm curtains for closing the spaces between the ends 'o'f'coupled or articulated railway cars.
The principal object-of the invention is to provi'de'a construction in which-the flexible curtains 'c'a'nbe made of inelastic material, "such ascoated 'or*uncoatedwoven textile material, thereby e1iminating the use of rubber, which is presently scarce "and is unsatisfactory because of its short ilife.
Another object ofthe invention is topr'ovide resilient mountings forthe curtains, which expand and contract under relative movement between the cars, "as when proceeding on curved track, without "placing 'undue strain 'on the curtains themselves.
Another object is to provide spring rollers on which the curtains are wound, and "to provide mountings for said rollers which permit them to turn with a minimum of friction and which te'xclu'de dust, rain and'snow.
.;Still further objects and advantages of the inyention will become apparent from "the "following description; which should be read with the understanding that the form, construction and arrangement of the several parts maybe changed Without departing "from the spirit of the invention as defined'in' the claims.
In the accompanying drawings:
Fig. 1 is a partly broken side elevation of the ends of adjacent articulated car's. Fig. 2 is a section on thefline .2-2 of Fig. .1.
.Fig. 3 is. a horizontal section, enlarged, of the roller and'its housing shown in Figs; 1 and 2.
Fig, 4 is a vertical section'of the roller showing its-bearingsand internal spring eonstruction Referring for the moment 'toTFigs. .1 and '2, the complete diaphragm comprises three separate curtains made of flexible inelastic material such as duck or canvas, which maybe (:OBJ' Bd .orsuite ably waterproofed if desired. There .a roof curtain 21 and two side curtains 22, one at each 'sideoi the \cars 23. Theside curtains 'ar-e identifoal, only one being shown .and described herein.
In the construction s'hownin 'Figs. -1 and 2, bot-h ends of the side curtain 122 :are attached to and wound upon spring operated rollers .24 mounted in bearings secured to the ends of cars-at their corners. The centeriof the'curtain :is at ta ehed. to-aa vertical; bar :25 whiohihas angle thewentralipm'tiun ottiiiee-eiirtazinaneathd's cs ifilaims. (01. arse-23 held in vertical po'sition'm'idway between tha'ends o'f the-ears. For additional strength and to preventsagging, the upper pivoted links 28 are made double, as shown in Fig. "1, there being one pair of horizontal 'links :28 and a pair of inclined bracing links 2 8a, the pivots of both pairs of links "being vertically aligned.
As the side *corners or the cars move toward :or away from ea'chtother'on curved track, the ends of the -cur'ta'in '2-2 are taken up or paid out by the spring rollers '24. There will be a small amount of in and out movement at the center of the ourtain, caused by the anguiairity of the links '21 and 2B, but this is-o'f no con-seq-uence-and'is also taken "care ofby the rollers 24.
Y Each Teller is constructed and mounted as shown in Fig. 4. It comprises a cylindrical tubular body '31 having heads 32 secured to its ends and mounted in ball bearings 33, Whose outer races are seated in *cups 3' 3 carried by angle brackets 35 secured to t-he end plate 39 and-corner post 3"6-oithe-car. "The upper head 32 has a'cen- 'tral aperture through which extends a spindle 31 whose upper end 38 is squaredor fia'ttenedand seats within 'a similarly "shaped aperture in the bracket 35. The spindle is thereby held stationar-y. intermediate head 39 is secured within the roller and has 'a step bearing "4'0 in which the lowerendof the spindle is rotatabl -mounted. A helical spring 41 surrounds the spindle within the roller, the upper end of said spring being fastened to "the spindle and the lower end being fastened "to the intermediate head 39. A few coils of the spring 41 at its upper end are wound tight around the spindle '31, as shown at 42, to distribute the s'tress, set up at the point of rigid attachment 43 between spring and spindle, and thus minimize breakage and promote long life. The "aperture through the upper head $2 "is considerably larger than the spindle 3'1, so that there is no friction at that point. 'The roller is therefore exceptionally free running, there being only "the two end ball bearings 33 and the intermediate bearing ill of the spindle 31. I'h'e'curtain (not shown inFig. i) is aftta'clhed to the roller in any conventional manner. 7
Each roller 24 is enclosed "in a housing to exthe curtain 22. The outer side of the housing is formed by a flat strip or flap 49 having a slightly out-turned forward edge 50, which is secured by a hinge 5| to the side plate 52 and corner post 36 of the car. The hinge 5| is provided with a spring of conventional type indicated at 53 which presses the flap 49 lightly against the curtain 22 wound upon the roller. The housing is thus sealed by contact with both inner and outer surfaces of the curtain, but can be easily opened to permit cleaning or removal and replacement of the roller. secured to the brackets 35 in any suitable manner, not shown.
