The ends of the side bar II are provided with caps` 31 and 38, as shown in detail in Figures 12,

13 and 1.4. and the ends of the side bar I2 are provided With similar caps 39 and lit. The caps are provided with plugs 4 I as. shown in Figure l2 and-end tubesv 42 and i3 are mounted on the plugs.

The ends of the straps Ill at one side of the platform are wrapped. around. the side bar Il and secured to the bar by stitches Ml and the ends of.- the straps at the opposite side of the platform are provided with buckles 45 that receive short straps 46 positioned on the cross bar I2, asv shown in FiguresA 1 and 2. With the straps arranged in this manner the ends of the straps Ill are'released from the straps i8- so that the straps Ill may be extended under a patient on the bedand then secured to the straps 46 by the buckles d whereby the patient carrying .platform is assembled under the patient without disturbing the patient and without overexertion onthe part of the nurse.

The telescoping posts. i3 and. l are formed as illustrated in Figure 4 with the upper outer sections I3 and Ill slidable over the lower sections I5 and I. The pistons and packing glands in both posts are similar and the same reference numerals are` used for both. As illustrated in Figures the tube Iii is provided with a bushing di in which a piston rod 68 of a piston B9 is carried and the piston is-slidably mounted in the inner or lower tube IG, which forms the cylinder. Toplace. the patient-carrying platform in position on theibed, the telescopic posts I3 and I6 are raised and then the" platform of the present invention is moved longitudinally along the bed. The end of the bed can be manuallylifted in order to clear the crossbar I9.

The piston 49 which isV secured on the lower end of the rod 48 is provided with annuiai'fgroov '4 59 for a piston ring 5I and, as illustrated in Figure 4 the upper end of the tube i6 is provided with a packing gland 52 and the upper end of the packing gland is provided with an opening 53 for a Spanner wrench or the like. The outer surface of the tube I6 is provided with a keyway or groove 54 and a key 55, positioned in a socket 5E in the outer tube Iii travels in the groove 54.

The lower ends of the inner tubes of cylinders l5 and It are positioned in Ts. 51* and 58 in which the end sections of the base'arms' Il and I8 are secured and, as illustrated in Figure 1 extend upwardly and over in the form of goose necks and casters 59 are provided on the outer ends. The cross tube I9 connects the ttings 5l and' 58, as shown in Figure 3 providing' communicating means between the lower ends of the cylinders ofthe posts,

The.V platform is elevated by hydraulic cylinders SG and GI mounted on a platform B2 and actuated by a foot lever 63 which is pivotally. mounted on the platform by hinges E4 and connected: to

piston rods 65 and te of the cylinders bylinks:

6l and. 53, respectively, as illustrated in. Figures.. l and 2. A spring 5s is providedv betrveenthel lower end 'i9 of the foot lever andv aolip 'l-.Lfor returning the lever to the upper position, as shown in Figure l.
