JOSEPH E. EAZAKEELEY, 0E PITTSEIELD, MASSACHUSETTS. I

HOSPITAL-BED.

To all whom it may concern.'

'Be it known that I, JOSEPH E. FAZAKER- LEY, a citizen of the United States, residing at Pittsfield, in the'county of Berkshire and State of/Massachusetts; have invented certain new and useful Improvements in Hospital-Beds; and I do declare the following to be. a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. y

My invention relates to that class of beds having` commodes and means-for bringing ythem into operative position when required,

the present invention being an improvement over the' construction shown by my U. S.

7,1916. The principal object of the invention is yto support the commode solely from the spring so that `it may move bodily with said spring as the latter yields under the weight of the patient.` i .A r

Another object is to provide improved and simplified means for operating the transversely separable sections of the spring and forv synchronously raising thelreceptaclef Yet another object is to provide a head and back rest so that if desired the occupant of the bed may be raised 'more or less to a sitting position.

With the foregoing general objects in view,-the invention resides in certain novel *features of construction and unique combinations of parts to be hereinafter .fully described and claimed, the descriptive matter being supplemented bythe accompanying A drawings which constitute a part' of this application and in which: I

Figure 1 is a top plan view of a bed spring embodying the present improvements;

ln the drawings above briefly described,

the invention is-applied to a bed .spring 1 s capable of vuse on practically any of the well known types of iron beds such as those commonly used in hospitals, sanitariums and the like. The ends of the spring 1 are anchored to transverse angle iron bars 2 having legs 3 atv their ends provided with outstanding feet 4 to rest'on the side rails w 5 of the bed, said spring 1 being preferably though not necessarily of the link and spring l construction shown. The spring 1` includes.

a pair of transversely separable sections 6 carried 'within' rectangular angle metal frames 9 which slide upon a main supporting frame 10 which is of rectangular shape and'is secured at its front and rear sides to the head and foot portionsI of the spring'l so yas to be supported thereby and movable bodily with said spring as the .latter yields under the weight of the patient.

The frame 10 is by preference though not Jslot connections at 14 with said outer flanges of the bars 12. By this arrangement the entire frame 10 and all parts carried thereby may be removed when required for cleaning and sterilizing.

Guide bars or tracks 15. depend rigidly from the centers of the bars 12 and receive thereon bearings 1'6 on the ends of a suitv able receptacle carriage 17 upon whichy an ',ppropriate receptacle 18 rests removably. Arched hinge supports 19 are carried by the tracks 15 as shown clearly in Figs. 3, 5 and 6 and the two. sections 20 of a receptacle cover are hinged to said supports so that when the receptacle 18 is raised by upward .movement of the carriage, said sections of the cover will be moved from the position of Fig. 5 to that of Fig. 6 so as to leave the upper side of the receptacle open for use.

Extending transversely beneath the spring 1 immediately in rear of the frame 10, is

an Aoperating shaft 21 having at one end a suitable handle 22 in convenient reach of the patient. The shaft 21 has-r` thereon a pair of bevel gearjsl 23 meshing'wth similar gears 24 on short longitudinally' dis- 26 meshing with rack bars 27 on the lower side of the frames 9. The shaft 21 is mounted in bearings 28 preferably formed integap formed between said frames and when the4 latter are again brought together, the carriage is returned to its initial position and the cover sections 29 close the upper side of the receptacle 18, which latter may bev removed whenever convenient, and replaced by another.

For operating the carriage 17 in the manner set forth, cables 30 are secured to the bearings 1G at one end and to the frames 9 at their other ends, the intermediate portions of said cables being trained over pulleys 31 carried by the. side bars of the frame 10. It will thus be obvious that as the frames 9 move outwardly they will pull upon the cables 30 and will thus raise the carriage 17 to raise the'receptacle 18 to operative position, at the same time causing the cover sections 20 to pivot around their hinges to permit unobstructed upwardA movement of said receptacle as will be clear from Figs. 5 and 6. Similarly, the return of the frames 9 to their initial positions will permit the cover sections 20 to again lower.

Particular emphasis is laid upon the fact that all parts of the commode and itsoper-` freely under his weight, there being noy fixed supports to prevent downward movement of the spring at all points between its ends.

Preferably employedl in connection with' the parts so far described, is a head and back rest in the form of an arched angle metal frame 35 which overlies the head portion of the spring 1, the two arms 37 of said l frame being pivotally mounted upon a posed shafts 25 which carry gear segments transverse rod 38 while the crown 39 thereof is equipped with arcuate rack bars 40 sliding through suitable guides a1 carried by the bar 2 at the head of the bed so that when said frame isA raised, said rack bars will hold the same in adjusted position. A handle 42 is preferably secured to bar 3 9 -forraising and lowering the same and by preference a transverse bar 43 will extend between the arms 37 to assist in raising the head section of the mattress.

The ends of the rods 38 are supported by vertically disposed plates ll which are secured to the spring in any suitable man.

ner although certain of the links of said spring are preferably passed through openings el in said plates as shown.

The provision of the head and back rest 35 permits the patient to move more or less to a vertical posture either when using the receptacle 18 or when expedient for other reasons, and it willbe observed that thev resiliency of the bed is by no means imthe scope of the invention as claimed, nu-

merous changes may be made without sacricing the principal advantages.

I claim:

l. `The combination with a mattress support including an open frame between the head and foot portions of said support and a pair of separable sections slidably mounted on said frame, of a shaft extending transversely of said mattress support adjacent the frame, bevel gears vsecured on said shaft, a pair of shafts at right angles to the afore- Saidshaft and having bevel gears meshing with the first named gears, gear segments carried by said pair of shafts, racks carried by the aforesaid separable sections and meshing with said segments whereby turning of the first named shaft. will separate said sections, a receptacle carriage below the aforesaid frame, and means for automatically raising said receptacle carriage when said sections are separated.l

2.
