HOSPITAL BED.

Application filed July 25, 1924. Serial No. 728,213.

This invention relates to a bed mainly designed for hospital use, the general object of the invention being to provide means whereby the bed can be rotated about a vertical axis and to hold it in adjusted position.

Another object of the invention is to provide means for changing the inclination of the bed as desired.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the invention.

Figure 2 is a plan'view.

Figure 3 is a sectional of Figure 2.

Figure 4 is a section on line 4+4: of Figure 3. j

Figure 5 is a detail view of one of the locking parts.

In these views, 1 indicates a supporting plate or disc to which the four curved legs 2 are connected so that this plate is supported in horizontal position above the floor. A second plate or disc 3 is rotatably mounted on the first plate by means of the ball bearings at and the stud 5 depending from the center of the plate?) through a hole in the plate 1, a nut 6 on the screw threaded end of the stud holding the parts in assembled position. ward from the top of the plate 3 and carries a pivot bolt 8 for the bed A, the bolt extending through the'angle irons 9 which are arranged at the center of the bed frame and are connected withthe end pieces thereof. The projection 7 extends between the two view on line 3-3 angle irons 9 as shown in Figure 4. Thusthe bed frame can be rocked about the pivot 8, as shown in dotted lines in Figure 1, and it is held in adjusted position by means of a rod 10 passing between the bars 9 and having a wedge latch member 11 fastened to itsinner end for engaging any one of a plural ity of notches 12 formed in the projection7. The other end of the rod passes throughla hole in'the end piece of the bed and is bent tion without disturbing him.

A flat'projection 7 extends upto form a handle 13 so that the rod can be pulled outwardly against the action of the spring 14 which tends to hold the membe 11 in engagement with the notch 12. a I also provide means for holding the plate 3 and the bed against rotary movement, such means comprising a bent rod 15 which passes through a hole formed in a side bar, of the bed and through a hole formedin a bracket 16 placed on the plate 3 and which has its inner end adapted to engage any one of a number of holes 17 formed in the edge of the plate 1. The other end of the rod is also bent to provide a handle 18 and a spring 19 tends to hold the rod in engagement with one of the holes 17.

From the foregoing it will be seen that I have provided a bed Which may be tilted to various positions or held in a horizontal position and rotated about a vertical axis. The bed is of simple but substantial construction and may be manufactured to sell at lowcost. It is very easy to keep clean so that it is sanitary and especially fitted for hospital use.

By having the bed rotatable about a vertical axis and tiltable about a horizontal axis the bed can be adjusted to place the patient in the most comfortable position and situa- It is thought from the foregoing description thatthe advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the. combination and arrangement of the several o parts, provided that such changes fall within thescope of the appended claim.

VVhat- I claim is A bed comprising a supporting plate,'-legs connected with the same, a second plate mounted on the first plate, anti-friction means between the two plates, a centrally arranged stud on the second plate passing through the ccnter of the first plate, a nut threaded on the bottom of the stud, an upwardly extending projection on the second plate having fiat sides with notches formed in one edge thereof, a bed frame pivotally connected with the projection so that it can be moved about a horizontal axis, said frame including a pair of parallel strips at the center thereof between which "the projection passes, with the pivot pin passing through the strips and the projection, a spring pressed locking bar carried by the bed frame and having a part adapted to engage any one of the notches in the projection for holding the bed frame in adjusted position, a sec-- ond spring pressed locking bar on the frame, the first plate having holes therein adapted to receive the inner end. of said last men engaging one of the holes in the first plat-e.

In testimony whereof I my signature,

JOSEPH oPoW. I
