MOSQUITO-CANOPY FOR FOLDING BEDS.

Application tiled March 3,1892. Serial No. 423,611. (No model.)

T0 all whom it may concern,.-

Be it known that I, ADDISON H. EVA, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas,

haveinven ted a new and useful Mosquito-Oan-- opy for Folding Beds, of which the following is a specification.

My invention relatesvto folding beds.

The object of my improvements is to provide a folding lbed of any variety with a canopy-frame for suspending a netting which will both fold up when the bed is closed and open when the bed is opened automatically.

The further object of my invention isto provide a canopy-frame with operating mechanism connecting the frame and the bed,where by no obstructions or guides of any sort are placed upon the walls of the bed-casing.

With these objects in viewmy invention consists of the following construction and combination of parts, wh ich will first be fully described in detail, and the features of novelty then pointed out and claimed.

Figure 1 is a perspective view of a folding bed, to which I have appliedmy improvements. Fig. 2 is a perspective view, hereinafter referred to, partly broken away. Fig. 3 is a detail view ot the hinged connection between the folding bed and the canopy-raisin g frame.

The folding beds shown by the drawings, to which in this instance I have applied my improvements, consist of a stationary upright bed-casing A, to which the folding bed B is pivoted at its lower end.

The bed-casing is preferably provided with standards O, between which is hung a rod E. To this rod is pivotally swung, by means of screw-eyes D, two rods F. The outer ends of the rods F are connected, by means of elbowjoints G, by a cross-bar H. The frame thus formed by the bars E, F F, and I-I constitute the canopy-frame, across which and suspended from the inosquito-netting hangs. The canopy-frame is opened and shut upon the corresponding movements of the folding bed by means of a raising and lowering frame consisting of two vertical bars I, which are pivoted at their upper ends to the canopybars F at J and at their lower ends to the folding bed -B by means of pivotal joints K therewith. These joints comprise brackets L, rigidly secured to the bed B, which are suitably journaled to receive a friction socket or tube M, which receives the lower ends of the vertical bars I.

Iii-many instances it is not desirable and in some cases impracticable to put guideways or attachments of any sort upon the. inner vertical walls of the bed-casing. In constructions of this kind all tendency of the netting to catch in the guides and guideways of the bed-casing and between the latter and the raising frame is entirely obviated. By attaching the vertical rods, which are pivotally connected to the bed directly to the canopyframe by means of pivots a very simple construction is obtained,which is at the same time remarkably well adapted for the purposes designed. f

Itl should be clearly understood that the vertical rods I have, in addition to their pivotal connection with the folding bed by the joint K, a sliding motion within the socket or tube M in the opening and closing of the canopy. This sliding or lost motion of the bars I and the tube M or its equivalent is.

necessary to the proper operative relation of the partsw when the bars I are pivoted directly to the canopy-frame. Otherwise the parts would lock the bed so that it would not opcrate.

I wish it further understood that I may provide for asliding connection at any other point along the vertical bars I. These sliding connections may be made in any manner suitable for the purpose.

The bottom of the tubular socket, which is hinged to the folding bed, is closed, as shown in Fig. 3, thereby forming a stop; This construction permits an initial lost motion of the tubular sockets upon the vertical rods I during the upward movement of the inner end or head of the bed, after which the stop en `gages thelower ends of the vertical rods and raises them and the canopy-frame. This special construction is necessary, because the travel of the hinged connection on the bed is greater than the pivotal connection of the vertical rod on the canopy-frame.

In a folding bed, the combination ot' a canopy-frame hinged to the top of the bed-casing, a raising-frame consisting of vertical rods 'pivoted directly to the canopy-frame at the ITI IOO

top, a slidable connection on said rods which In testimony whereof I hereunto set my permits an initial 10st motion upon the openhand this 25th day of February, 1892. ing of the bed, a stop which comes into oon'- Y tact with said Vertical rods at the limit of the ADDISON H' EVA' 5 lost motion and elevates them, a bed-easing, Witnesses:

and a folding bed hinged thereto, to which P. R. DE LASHMIN, the raising-frame is pivoted. JOHN C. BOAK.
