DEVICE FOR WORKING UPRIGHT FOLDING BEDS.

SPECIFICATION forming part of Letters Patent No. 375,183, dated December 20, 1887.

.Application filed January 12, 1887. Serial No. 224,151. (No model.) 4

T0 aZZ whom it may concern.-

Be it known that 1, JOHN MURRAY, of Fort \Vayne, in the county of Allen, State of Indiana, have invented a new and useful Device for the Working of Upright Folding Beds; and I do herebydeclare that the followingisa full, c1ear,and exact description of the construction and operation of the same, reference being had to the accompanying drawings as making a party of this specification, in which Figure 1 is a rear perspective view of one corner of a folding bedstead at the head end embodying my improvements. Fig. 2 is a side elevation of the same with lowered side rail shown in dotted lines. Fig. 3 is a front elevation with side rail raised. Fig. 4 is a perspective view of my improved guiding and balancing devices for the side rail. Fig. 5 is a modification of the same.

The object of my invention is to provide a simple, cheap, and improved means of balancing and guiding the side rails of upright folding bedsteads; and to this end the invention consists in the construction and combination of devices hereinafter described and claimed.

Referring to the drawings, the letter I) designates one of the stationary uprights forming part of the sides'of the bed-casing, and a and c are cross-pieces for connecting the two uprights.

To the inner side of each upright bis firmly secured a bearing-block", 6, having a rearwardly-inclined upper surface, as shown in Figs. 1 and 2.

In the inner side of the bearing-block e, between it and the upright b, is formed a diagonal groove or guidcway, d, which receives a slide or guide bar, A, pivotally connected to a rocker, D, that is secured to the rear end of the side rail, 0. as shown.

, The rocker D rests on the upper inclined surface of the beariug-block e, and is adapted to turn or rock thereon in such a manner as to change the pivotal point of the side rail nearer its center when the bed is in a horizontal position or approaching the same,while the slide or guide-bar Amoves upward in the groove d, thus guiding and holding the bed and enabling it to be balanced with greater case than usual.

The guidebar A and rocker D may be connected by a pivot-bolt,f, if desired, in which case it is preferable to cut away one side of the rocker to receive the upper end of the guidebar, as shown in Figs. 1, 3, and 4; or, instead of the pivotf, the bar A and rocker D may have a hinge connection, G H, as shown in Fig. 5.

The guide-bar or slide A, rocker D, and bearing-block 6 can be made of wood or metal, as desired; but if made of wood it is preferable to face the wearing-surfaces with metal.

What I claim is v e In a folding bedstead, the combiuatiomwith the upright b and movable side rail,'0, of the bearing-block e, secured to said upright and provided with a diagonal groove, (1, and an inclined upper surface, the rocker D, secured to the rear end of the side rail and resting on the inclined upper surface of the said bearingblock, and the slide or guide-bar A, pivotally connected to the rocker and adapted to move in the groove (1, substantially as described.

JOHN MURRAY.
