GEORGE \V. BENT, OF HYDE PARK, MASSACHUSETTS.

BED.

SPECIFICATION forming part of Letters Patent No. 589,239, dated August 31, 1897. Application filed October 17, 1896- Serial No. 609,174. (No model.)

T 60% whom it may concern.-

Be it known that I, GEORGE W. BENT,"residing in Hyde Park, in the county of Norfolk and State of Massachusetts, have invented Improvements in Beds,'of which the followingdescription, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates to extensible bedbottoms of that class in which the bed-bottom is composed of a series or plurality of bars connected together at their ends to form pairs, which are also connected at their center, so as to expand and contract, each of the said pairs having hangers attached to their ends, which hangers are adapted to engage and be supported bythe side rails of a metallic bedstead.

In order to secure lightness in the frame of the metallic bedstead, the side rails are made as light as possible consistent with safety, and these side rails are commonly made of angleiron, and when the bed-bottom referred to is attached to the side and end rails of the bedframe by hangers secured to each pair of bars comprising the bed-bottom the side rails of the bed-frame are liable in use to buckle or bend at their center, and more especially if the bed is used to support a substantially heavy weight, for by reason of the bed-bottom being attached to the side rails near their longitudinal center each of the said side railsis practically converted into two substantially long levers with the points of attachment of the said rails to the head and foot frames as pivots, so that when the weight of a person .or persons is placed upon the bed-bottom it is transmitted by the center hangers to the center of the side rails, which increases the leverage and with light side rails causes the same to bend or buckle.

My present invention has for its object to improve the class of bed-bottoms referred to, so as to avoid the buckling or bending of the side rails and permit them to be made substantially light when used with this class of bed-bottoms and at the same time render the bed-bottom strong enough to support the weight placed upon it, and I accomplish my object by disconnecting the center pairs of bars from the side rails and providing supporting-bars, which extend under the center connected with h an gers,which engage the siderails' near their attachment to the head and foot frames, so that the weight placed upon thebed-bottom is transmitted to the side rails near their ends, which avoids bending and I buckling of said rails and permits the latter to be made substantially light.

Figure 1 .is a perspective view of a bedframe provided with a bed-bottom embodyingthis invention, one of the side rails being broken out; Fig. 2, a side elevation of the bed frame and bottom shown in Fig. 1; Fig. 3, a detail of one of the supporting and connect- .ing bars shown in Fig. 1.

Referring to the drawings, a a represent the side rails of a metallic bed-frame having a head and foot frame to which the side rails are detachably connected, the said headframe herein shown com prising the posts a a and cross or end bar a and the foot-frame comprising the posts a a and cross or end bard". The side rails a a are detachably connected to the head and foot frames, and in the present instance this connection is made by means of lugs a on the ends of the side rails entering sockets in castings a on the posts of the head and foot frames.

The metallic bed-frame is provided with a detachable and extensible bed-bottom composed of a series or plurality of pairs of'bars b bof substantially the widthof the bedframe and preferably firmly united at their opposite ends, as by rivets b the said pairs being alsofunited near their center, as by rivets b If, the bar I) of onepairheing fastened to the bar I) of an adjacent pair. The pairs of bars I) h are suspended from'th'e siderails a a, preferably as shown in Fig. 1, by means of hangers b riveted or otherwise fastened to the ends of the pairs of bars adjacent to the endmost pairs of bars I) b, and which hangers engage or fit over the side rails, and the said bars may also be suspended'from the end rails a a by hangers b riveted to the endmost bars of the bed-bottom. In acposite ends hooks or hangers 3, the center portion 2 of the bar 72 being adapted to extend under the ends of the center pairs of bars I) b, and the hooks or hangers 3 being adapted to engage and rest upon one of the bars I) 'b of the pairs to which theside hangers b are secured, as shown in Figs. 1 and '2.

It will be seen that the pairs of bars constituting the center portion of the bed-bottom are firmly supported "by the bars 19 and that the sides of the bed-bottom are supported by the side rails, butit will also be noticed that the hangers 11 which support the'sides of the bed-'bottolmengage the side rails near their oppositeends, and asa result the side rails are not subjected to a strain or leverage, as will be liable in ordinary usage, to bend or buckle the same. The supportingbars 19 for the sides of the bed-bottom may be readily detached or unhooked from the bars I) -b of the bed-bottom to permit the spring-bars b b to contract or fold after the hangers b b are detached from the side and end rails of the bed-frame.

I prefer to rivet the ends of each pair of bars 1) I), but such rive'tsmay'be orn itted and the said bars fastened at their center only.

I'claim-- l. A'bedsteadbottom consisting of a plurality of pairs of bars connected together intermediate of their ends, suppor'tin g-bars extended longitudinally under the ends of the center pairs of bars and engaging bars of pairs located on opposite sides of the center pairs of bars, and hangers attached to the pairs of bars with which the supporting-bars are connected, substantially as described.

2. Thecoinbin'a tionwith a bed-frame having side and end rails, of an extensible bedbottom composed of a plurality of centrallyconnected bars b b, hangers attached to the end bars to engage the end Tails of "the bedframe, hangers "attached to the ends of the pairs of bars "on :opposite rsides of the central pairs of bars for "engagement with the side rails of the bed-frame near the opp'osiit'e ends of the same, and bars *b einten'ded under the ends of the centrally-disposed pairs "of bars "Z1 Z2 and provided with books iorhangersffor engagement with the ends of the bars I) 'b of pairs to which the side hangersiaresecured,

substantially as described.

in testimony whereof :I have signed Inry nar'ne to this specification in the presence of two subscribing witnesses.

GEORGE BENT. WVituesses JAs. H. CHURCHILL, J. MURPHY.
