SPECIFICATION forming part f Letters Patent N O. 517,462, dated April 3, 1894. Application led February 9, l 893. Serial No. 461,558. (No model.)

.To all whom it may concern:

Be it known that I, EDWARD LAWSON, of Birmingham, England,have invented certain -new and useful'lmprovements in or Relating tached respectively to the beams of the deck overhead and to the deck on which the berths are erected. These berths areusually grouped together in blocks so that each pillar may have to support one corner of each of eight berths, viz-four in an upper tier and four in a lower tier. Between the pillars are fixed the head and foot rails and the side or lee rails, and the berth bottoms are provided with hooks which engage with the lower bars of the said side or lee rails or oty the said head and foot rails, as may be preferred. Heretofore the pillars have been constructed with collars having bulbous shaped sockets cut away opposite the berth bars, and the bars have carried rigid bulb shaped ends of less size than, and entering and loosely fitting these sockets, and when therein projecting through the cut away portions thereot'. This arrangement has permitted some slight disv placement, both horizontally and vertically of the bars relatively to the posts, but the necessarily loose lit between the sockets and the ends of the bars has permitted much rattling and chattering between these parts. Berths of this class are generally used for the accommodation of steerage passengers.

The objects of my invention are to make better provision for horizontal displacement the berths necessitated by sheer of the sides of of the ship and-for vertical displacement of the berths necessitated bysheer or convexity of the decks; to insure a close it between attached parts and thereby obviate the objectionable clatter or chatter which has hitherto been produced in berths of this class because of imperfectly iitting parts; and to simplify the construction of the berths.

My invention consists in the combination of vertical conical plugs on the ends of the upper and lower'bars of the head, foot and vlee rails, and of collars fixed to the supporting pillars, said collars having vertical conical sockets to receive the conical plugs on the ends of those bars of the head, foot and lee rails that are to be fitted thereto, and each of said sockets being partly cut away at the side in the direction of `the corresponding bar to allow of horizontal displacement of said bar.

My invention further consists in the combinationr with a plug adapted to tit into a cor,- responding socket in a collar fixed to the supporting pillar, of a piece at one side of said plug formed integrally therewith and attached by means of a horizontal pin or pivot to the end of the berth bar that has to carry said plug, whereby said bar can be displaced vertically.

My invention further consists in the construction of the head, foot and lee rails withv upper and lower bars in the form of hollow tubes'of flattened section,'the fiat portions constituting the sides of the bars, and with vertical bars of solid tlat section connecting' said upper and lower bars, the ends of said vertical bars entering slots in the edges of said upper and lower bars and being attached.

thereto by horizontal pins onwhich they can move or pivot, so that the berth can' be inclined if required.

My invention comprises other minor or subsidiary improvements the nature of which will be understood from the description hereinafter given. v

In the accompanyingdrawings Figure l is a plan of two berths in-the construction and mounting of which my improvements are embodied. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation, the collar and a portion of the horizontal bars being in vertical section, showing in position and on a larger scale than Figs. 1 and 2 a part of a supporting pillar, a collar Iixed thereon and a part of two horizontal bars with the corresponding plugs and connecting pieces. Fig. 4: is a plan on the same scale as Fig. 3 showing in position a supporting pillar, a collar fixed thereon and parts of four horizontal bars with the corresponding plugs and connecting pieces, the pillar and a portion of one of the bars and of the corresponding connecting piece being in horizontal section. Fig. 5 is a side elevation on the same scale as Figs. 3

IOO

and 4 of a portion of the upper and lower bars of a head, foot or lee rail and of one of the vertical bars connecting said bars, the said upper and lower bars being in section at and near the points of connection. Fig. 6 is a section on the line G-G of Fig. 5,part of the vertical bar and the connecting pins being in elevation.

In the drawings a, a represent the pillars which support the berths; they fit at their lower ends into sockets b h attached to the deck c, and their upper ends which are not shown fit into sockets attached to the beams of the deck overhead.

d d are collars fixed to the pillars a a in the same horizontal lines or approximately so as the upper and lowerbars of the head, foot and lee rails. These collars are formed with conical sockets e c, the larger end of the cones being uppermost; the number of sockets c e in each collar (Z will be determined by the number of berths that are to meet at such collar; in the case of a collarat the middle of a block of berths the number will be four, and in the case of a collar at the side of a block only three are required, and in the case of a collar at the corner of a block only two. Each socket is cut away or formed with a gap fin the direction ot' the corresponding berth bar, the said gap extending from the top to about half its depth, and being of sufcient width to not only receive the neck connecting the piece g hereinafter described with the corresponding conical plug, but also to allow space for horizontal displacement of this piece to either side.

h h are conical plugs which fit the conical sockets e e. Each of them is formed integrally with the neck of a piece g which is attached by means of a horizontal pin or pivot i to the end of the corresponding bar of the berth. The said bar can therefore be displaced vertically as may be required.

jj are the upper bars and k k the lower bars of the side or lee rails and l Z the upper bars of the head and foot rails, the lower bars of which are not seen in the figures. The said upper and lower bars of the lee, head and foot rails are constructed of hollow tubes of flattened section, the fiat portions constituting the sides as clearly seen in the figures. In the under side of the upper bars, and in the upper side of the lower bars are formed slots m m to give passage respectively to the upper and lower ends of the vertical bars o o which connect said upper and lower bars. The said vertical bars are of solid flat section, and their ends are attached to the upper and lower bars by horizontal pins n n on which they can move or pivot to allow the berth to be inclined if required, for which purpose the slots m m are made suiciently long to permit of the pivotal movement.

The berth bottoms, which are best seen in Fig. l, are shown as composed of two longi tudinal angleiron bars p p, two end cross bars p p', and an intermediate cross bar p2,

all three being rounded at the ends and riveted under the horizontal portion of the bars p p so as to allow the berth bottoms to sheer with the lee rails.

pijas are longitudinal laths jointed at their ends to the end bars p', and p4 p4 are cross laths similarly jointed to the longitudinal bars p 1J. The longitudinal bars p p have hooks q q to enable the berth bottoms to be att-ached to the lower bars of the side or lee rails, or alternatively the hooks maybe on the end bars p p of the berth bottom so as to hook on to lower bars of the head and foot rails.

In cases where, as shown in Fig. 1,the head and foot rails have to support the ends of an intermediate lee rail instead of this rail being supported by pillars, blocks 7 (Fig. l) formed with vertical conical sockets like the sockets e e in the collars d are fixed to the head and foot rails at the center of their length to receive the conical plugs of the lee rail which is to be supported therefrom.

Then vertical displacement of the upper and lower bars of the head, foot and lee rails has not to be provided for the piecesg which connect the plugs 72, h to the ends of said bars may be rigidlyixed to said bars, the pins or pivots i i being dispensed with. On the other hand the mode of connecting the plugs 7L 7L with the ends of said bars by means of the pivoted connecting pieces g gcan be applied to plugs or terminals of other than the vertical conical form shown, and in combination with sockets not of the conical form shown, but the vertical conical form` of the plugs or terminals h h and the correspondingly shaped sockets e e as shown are greatly preferred, because this construction obviates, and is specially designed to obviate, the objectionable clatter or chatter which is more or less inevitable with other forms of terminals and sockets.

The flat tubular horizontal bars of the berth rails and the flat solid connecting vertical rails make a strong berth and occupy the minimum space horizontally, while the fact that the horizontal bars are tubular and the vertical bars are solid enables the articulated connections between them to be readily made by means of the pins n n.

What I claim, and desire to secure by Letters Patent, is

1. In a berth supported by pillars, the combination with the supporting pillars, of collars fixed thereon and having sockets, the horizontal bars of the berth frame, plugs carried on the ends of said bars and entering and fitting said sockets of said collars, and a pivotal connection z' between said bars and plugs having a horizontal axis, whereby when said plugs are :[itted home in said sockets said bars can be tilted vertically relatively to said plugs on said pivotal connections, substan tially as set forth.

2. In a berth supported by pillars, the con1 bination with the supporting pillars, of collars ICO ich
