' SPECIFICATION forming part of Letters Patent No. 511,533, dated December 26, 1893.

Application filed March 28, 1893.

To all whom it may concern:

Be it known that I, ALAN E. LARD, of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Irnprovements in sleeping-Car Berths; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in sleeping car berths of that class in which two oppositely facing adjacent seats, are adapted to be converted into a bed or couch, forming what is commonly known as a lower berth.

The object of the invention is to provide an improved construction in improved car berths of the character referred to, and it consists in the matters hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a sectional elevation of a group of car seats embodying my invention, the two middle seats being arranged to form a bed. Fig. 2 is a side elevation of the two middle seats folded up to make room for dressing, the side panels of said middle seats being removed to afford a better view of the structure. Fig. 3 is a plan view of Fig. 1, the mattress being removed. Figs. 4 and 5 are details of the spring catch for supporting the seat proper, and the mechanism for releasing said catch.

In the drawings, A A dosignate several car seats constructed in accordance with my invention,' each two oppositely facing adjacent seats being designed to be converted at will into a bed or couch. Said seats each comprise a pivotally supported back A' adapted to fold down and co-operate with the back of the opposite seat to form the bed bottom, and a seat bottom A2, also pivotally supported and adapted to swing down out of the way when the back A' is dropped. As herein shown said back A' consists of a rectangular frame work provided near its lower end with laterally projecting pivots a engaging suitable bearing apertures in the side panels B of the seat. Said bearing apertures are located a considerable distance in front of the rear wall B' of the seat, leaving a space be- Serial No. 467,970. (No model.)

tween the pivots and the rear wall B' is in this instance bridged over by extending the frame of the back A' an equal distance below said pivots, such lower portion swinging up to fill the space when the upper portion of the back is dropped, and in such case it will be obvious that the length of the back A' will be approximately equal tocne half the distance between the rear walls B' of the two seats.

As hereinbefore stated the seatl bottoms A2 are adaptedto swing down outfof the way when the backs A' are dropped and to this end each of said seat bottoms is herein shown as provided With the rearwardly and downwardly projecting brackets a' pivotally secured by pivots a2 to the side panels B of the seat, said pivots a2 being herein shown as 1ocated adjacent to andA below the pivots a, of the back A'; Each of said 'seat bottoms is supported in front by spring detents O adapted to be retracted to permit the bottom to swing down. In this instance the retraction of said detents is accomplished automatically by the movement of the back A' each of said detents being to this end made integral With, or otherwise connected with, one end of a bell crank lever C' which ispivoted to swing in a horizontal plane within a convenient recess b in the adjacent side panel B. The other end of said bell crank lever is connected by a link Czto a tripping lever G3 pivoted to the panel B at a point adjacent to the pivots a' and extending downwardly in the path of an inwardly projecting pin or Iug a3 provided on the lower portion of the back A'. The extreme end of the lever 03 stands nominally just behind the said pin a3 so that when the back A' is dropped said pin will force said lever G3 rearward and thereby retractthe deis pivotedfto the body of the lever in such Atoo manner that it will yield freely when struck by the pin ot on its return movement andpermit said pin to pass, but will not yield in the opposite direction. A suitable spring c placed behind the lever C' serves to nominally maintain the detent in its protracted position. As herein shown all parts of the detent mechanism thus described are located within said recess b which is made of suitable shape to receive said parts, and has an arc shaped extension b' within which the pin ai' travels, the ends 62 and 113 of the extension b' serving as steps to limit the movement of the back A'.

As herein shown the rectangular frame of the back A' is formed of side bars A3 A8 and upper and lower cross-bars, A4 and A5, respectively, forming a frame of considerable width, within or upon which any suitable form of bed spring may be used. That shown in this instance consists of a sheet of woven wire A6 stretched across the rear face of the frame and attached at its edges to the side bars A3 and lower cross bar A5.

To avoid an unyielding bar across the middle of the bed the upper cross-bar A4 is made of less width than the other bars of the frame and is attached to the front face thereof, leaving the woven wire A6 unsupported and free to yield at its upper edge. As a further improvement, said upper edge of the woven wire A6 is provided with a short flap A7 made either integral therewith or in a separate piece suitably jointed thereto, said flap being adapted to lap over the woven wire fabric of the opposite seat back and form a more continuous surface. A horizontal ledge 132,V attached to the rear wall B' of the seat, bends down and conceals the fiap A7 when the back A' is raised. The front face of the frame is also herein shown provided with a sheet A8 of woven wire which serves to support the usual upholste'red cushion A9 of the seat back.

In order to facilitate the moving or lifting of the seat back or frame, I preferably provide a counter balance weight A10 which is Secured to the lower part of said seat back below the pivots thereof, in the manner shown.

Any suitable mattress capable of being readily folded may be used upon the bed bottom formed by the dropping of the seat backs A'. That shown in this instance consists of two flexibly connected sections D adapted to be removed and stored in the upper berth in the usual manner, the connection between the mattress sections being 1ocated in the same plane with the upper surface thereof, so that the parts of the mattress may be folded together flat or without being bent, in the manner shown. As a further improvement `said mattress is herein shown as made of less length than the bed bottom leaving Spaces at each end of which are occuped by separate mattress sections D' permanentlyattached to the lower ends of the rear faces of the seat backs A'.

The construction of my improved car seats being as described their operation when used as seats will be obvious. VVhen itis designed to convert them into a bed the backs A' A', first of one and then the other, are swung down, each by its movement releasing the detents C and permtting the sea-t bottom to drop out of the way. The mattress sections D are then placed in position and the bed made up in the usual manner, ready for occupancy. One section D of the mattress together with that portion ot' the bed clothing above the same is then turned down upon the other section, and the seat backs A' raised bringing the parts into the position shown in Fig. 2, leaving a conveniently large space for undressing in; the bedding being prevented from slipping down by the permanently secured mattress section D'. VVhen ready the occupant steps into the aisle (protected by the berth curtains) swngs down the seat backs A', turns back the mattress and bed clothing and gets in. In arising the operation is simply reversed. The occupant steps into the aisle, turns back the mattress and bed clothing raises the seat backs again to the position shown in Fig. 2, and dresses in the space thus provided.

To facilitate the manipulation of the bed clothing the mattress sections D may be provided near their outer ends with two or more buttons (Z and the lower sheet may have at one or both ends button holes for engaging said buttons. In this case the sheet will be buttoned to the mattress section which is at the head of the bed, and that mattress section to which said sheet is buttoned, will be the one Which is turned back. As a consequence when the seat backs A' are again dropped and the said section D returned to place it will bring with it the lower sheet, leaving the other bed clothing turned back, as shown in Fig. 1, ready for occupancy.

From the foregoing description it will be noted that the central idea of my invention consists in so constructing the seat backs of a lower berth, that after being dropped to form the bed bottom, and after having the bedding placed thereon, they may be conveniently folded up without materially disarranging the bedding, to provide space for the occupant to undress or dress in.

While I consider the specific form illustrated as the best mode I have yet contemplated of applying my invention, it is obvious that numerous minor changes might be made without departing from the spirit of my in- Vention. Thus it is obvious that the seat bottom A2 might be rigidly attached to the back A' and if too long to swing clear of the floor, the latter might-be recessed to receive it. Obviously also the seat back A' might be terminated at the pivots a and that portion now extending below said pivots formed in a separate piece and attached to the rear wall B', or otherwise. So also the separate mattress sections D' might be dispensed with, and the sections D made long enough to extend from VI oo IIO and to the end of the berth. All such and similar modifications, however, I consider within the scope of my invention.
