v BERTH LADDER FOR SLEEPING CARS Application led March 25, 1931. Serial No. 525,237.

This invention relates to new and useful` berth thereof. The primary object-of the in# vention resides in the provision of a ladder Structure that is permanently associated with an upper berth of a sleeping car and that may be readily folded and swungv into the upper berth when the same is drawn up against the roof of the car so as not to be in the wav when the berths are not being used.

further and important object resides 1n the provision of a ladder of this construction that may be moved a predetermined extent throughout the length of the upper berth and that includes means forlocking the ladder against collapsed condition when the same 1s 1n use.

A further and important obj ect is to pro'- vide a ladder construction of this character that is relatively simple in construction, 1nexpensive of manufacture and one that may be readily associatedy with upper berths of sleeping cars in a simple and easy manner, and this without altering the "construction of said berths to any extent whatever.

With the foregoing and other objects inv view as the nature of the invention will'be better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed. In the drawings wherein like reference characters indicate corresponding parts throughout the several views: p

Figure l isa front Velevation of my 1mproved ladder as actually associated with an upper berth of a sleeping car, the outer wall of said upper-berth being partially broken away for more clearly disclosingthe longitudinal Supportingbar with which the upper end of the improved ladder is pivotally associated. A y* Figure 2 is a fragmentary transverse section throughv theupper berth structure for disclosing my improved ladder in side elevation. Y Y

Figure 3 is a front elevation ofthe ladder incollapsed andraised position just prior to being sw-ungover into the. upper berth unit.

Figure is a side elevation of the upperl berth ,disclosing the ladder in dotted'lines having been swungover into position therein so as to facilitate the swinging Vof the upper berth against the carceiling.

`Figuren is a fragmentary transverse Section through the outer side of the upper berth disclosing the ladder as having-been'swung into position therein. 1 f 1 j Y Figure 6 is anrenlarged fragmentary rear side elevation of theladder structure for more clearly disclosing the means for securing the ladder yagainst collapsing, there'being com,- plemental to saidmeans a swinging latch -to facilitate vthe locking ofthe means so asto prevent the accidental collapsingof the ladder when in use. f

`Figure 8is a fragmentary elevation of One side of theladder for disclosing more clearly 7 the swinging latch unit or securing thev ladder locking .element in operative position.k Y

Figure v9 is a perspective Y of a modified means of attachmentlof the ladder to the upper berth. 'f l Now having vparticular reference to the drawings, A designates generally a single uppergberthl frame of the conventional design of sleeping car with which the presentV lad-y der structure'fis associated. Arranged upon the inner face of the inner side wall of this upper berth fram-e is a pair of longitudinally spaced bracket plates 5 5, the upper edges of which are formed with inwardly extending longitudinal sleeves 6, withinl which are sevycurely arranged the oppositev ends of ahorizontal ladder attac'hingbar'. The ladder construction, per se consists of a pair of legs 8 8 of predeterminedplength and preferably of Lp-bar configuration as disclosed in the main view. These legs 8 8 are joined by metallic L-bars for providing spaced rungs 9, the oppositeends-thereof being pivoted to the legs 8 8 so as to-permit the said legs to be swung toward each other when-itis desired to col# lapse the same, the outer ends of the back wall of these rungs being rounded as clearly disclosed in Figure 1 so as to facilitate their pivotal action with respect to the legs when said legs are folded.

Pivotally secured to the lowerends of these legs 8`8 are inwardly extending Vbracing straps 10-10 the extreme inner endsof which are bent downwardlyfor providing'feet 10a K forfrest uponV thercar licor adjacent the lower feet units B-B of the lower berth construction. v n

The invention further consists of a double goose neck 11, the inner'wsingle endfbei-ng.,

formed with a sleeve 12 for sliding engagement upon the horizontal berth framey carrying Vbar 7, the necks of this unit divergingy outwardly and being pivoted to theinnerside ofthe angle bar' legs 8--8, as 'clearly disclosed in both Figures '1 andV 2. The upper endY of the outer side of one of the legs is formed with a slot'13 so as to permit-this end of theleg to swing lbeyond its associated goose y neck when the legs 8*-8 are swung upwardlyinto the position disclosed Figure 3. Gbviously this particular attachment between the ladder andthe'frame A'of the upper berth will permit/the ladder'tov be readily moved longitudinally tothe desired point with re- Y spect to the berth.l

oted to the respective-leg 8'alatch dogr17` notchedatits lower endfas at18 for receivingA the finger 415`V of the arml 14 whenthe same is swungrdownwardly as indicated by the curvedline in Figure 6.v Obviously this dog will prevent 'the upward swinging ofthey armlet and the consequentdisengagement of the' finger l5 from the slot 16 in the leg 8 so that while.V in engagement therein itwill be impossible to collapse the leg to the position Vdisclosed in Figure 3.

After the ladder has been collapsedand extendedinto the raised horizontal position `shown in Figure S'byreason ofthe goose neck connection between the ladder and the horizontal supporting bar, the entire ladder together with the gooseA neck-may be swung over into the frame A as indicated bythe arrow in Figure 2. n

In FigureV 9 the berth attaching bar is designated 7"and the endsxthereof are formed with inwardly offset attaching brackets 54-5 forfacilitating the attachment' of the barl to theupper berthA' in yan obvious man'- ner. Loosely slidable on this bar is a sleeve 10 formed with an upwardly extending plate 11 to which is rigidly secured a horizontal flat-like bar 12. Rigidly secured to the opposite ends of this bar 12 are the inner short ends of a pair'of goose necks 1313 which extend outwardly of theupper berth'A and to the opposite ends of which are pivoted the upper ends of the ladder legs 8.-8,.

It will thus be seenthat Ihave provided `a highly novel, simple, and efiicientlladder t for thel upper berths of sleeping cars'that is well adapted'forall the purposes heretofore designated;v Evenwthough I have herein shown and described the invention asconsistin'g of certain detailstructural elements it is nevertheless tobe understood Y'that 'some changes'may be made therein without aect ing the spirit and scope of the` appended claims. K i

Having thusdescribed the invention, whatV I claim is:
