WALTER H. SAWYER, OF JACKSONVILLE, FLORIDA. .y

INVALID BED.

To all whom 'it may concern.'

Be it known that I, WAUrER I-I. SAWYEB, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented a new and is a specication. Y

'Ilhis invention relates to invalid beds for use inhospitals and the like, one of its objects being to provide the bed with a sectional mattress including an intermediate stationary section, a movable head section, and separately movable leg sections, there being yielding means under the control of the operator for raising and lowering the movable sections at will.

A further object is to provide operating means which will hold the sections in any position to which they may be moved without necessitating the use of special locking means.

A further object is to pnovide a single voperating element whereby either or both of the leg sections of the mattress can be raised or lowered.

A still further object is to provide a bed of this character the oppositely projecting head and foot portions of which can be removed when it is desired to use the bed as an operating table.

A further object is to provide a bed of this character having an attachment by means of which a tray or other article can be held in position over the bed -for use by the patient.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, withinthe scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

vIn said drawings- Figure 1 is a side elevation of the bed.

Figure 2 is a plan view thereof.

Figure 3 is a longitudinal section, the movable sections being shown shifted out of their normal positions.

legv sections.

Figure 7 is a faceview of the worm gear of the mechanism shown in Figure 6.

Figure 8 is a face view of the clutch member shown in Figure 6.

Figure 9 is a section on line 99, Figure 6.

Figure 10 is aview taken on the same line as Figure 9 but looking in the opposite direction to show va portionof the shifting lever and the end of the shiftings'leeve v Figure 11 Vlis a plan view of the' head portiony of the mattress supportingframe.

Referring-to 4the figures by characters of reference 1 designates the side rails of the bed supported by legs 2 mounted on casters 3 so that the bedcan be readily moved from place to place. Corner brackets 4 connect the legs 2 to the side rails 1 and have sockets 5 in their upper ends for the reception 'of vthe lower ends of the side portions ofthe head and foot members '6 of the bed and which members can be readily lifted out of place when the bed is to be used as an operating table.

Cross strips 7 connect the side railsv adjacent the center thereofand support an intermediate frame 8 on which the central section 9 of the mattress is adapted to be mounted. Depending from these cross strips vare hangers 10 having cleats `11 Afor 'holding a shelf 12 on which a bed pan indicated at 13 may be mounted. It is of course to be understood that an opening ,14 may be provided within `the section 9, this opening being normally closed by a plug y15 .or'the like. Secured to the side rails 1 are brackets 16 extending downwardly and constituting bear'- dle portion vof this shaft is ysecured 4a segmental gear 18 constantly in mesh with a worm 19. This worm is carried by a short longitudinal shaft 20 one end of which is journaled in a bearing 21 carried by one of the .hangers 10 while the other end portion lof the shaft 20 is journaled in a bearing 22 carried by a cross strip 23 which connects the legs 2 at one end of the bed. A crank 24 or the like may be connected to the projecting end of the shaft 20 so as to permit it to be rotated readily. Secured to the shaft 17 are brackets 25 and from each of these brackets extends a resilient linger 26. A frame 27 is hingedly ings for a transverse shaft 17.

rails l.

connected to one end portion of the frame 8 and carries a movable mattress section 28. This frame 27 bears upon the resilient fingers 26 and it will be obvious that by rotating the shaft 20 motion will be transmitted through the Worm 19 to the mutilated gear 18 so that the fingers'26 will thus be raised or lowered so as to cause the frame 27 and the mattress 28 to be raised or lowered relative to the side Obviously when the mattress section 28 is in any position the resilient fingers 26 are' yieldingly supported, thus addingmaterially to the comfort of the occupant of the bed. As the worm 19 and gear 18 are utilized for transmitting motion from the shaft 2() to the movable mattress section, said mattress section will obviously be held in any position to which it may be moved Without requiring the use of special fastening means.

-Another setof brackets 29 extend downwardly from the side rails 1 and have a shaft 30 journaled in them. This shaft has a mutilated gear 31 loose thereon and constantly in mesh with the worm 32 carried by a longitudinal shaft 33. One end of the shaft 33 is journaled in a bearing 34 carried by one ofthe hangers 10 while the other .end of the shaft 1s journaled in a bearing 35 carried by a cross strip 36 connecting the legs 2 at one end of the bed. Ancrank 37 or the like is connected to the projecting end of the shaft 33 and by means thereof motion may be transmitted from the Worm 32 to the gear 31 and shaft 30.

The gear 31 is mounted upon the middle portion of the shaft 30, as shown particularly in Figure 6 and hasa circular series of openings 38 extending transversely therethrough. v Mounted to slide and rotate upon the shaft 30 at opposite sides of the gear 31 are elongated sleeves 39 each of' which is provided, at'V that end nearest the gear 31,

- with a clutch head or disk 40 provided with 4,8. 1 l, Frames 49":

4ou'twardl extendin'L coupling pins 41. The outer en of each s eeve 39 has a-collar 42 secured to it and engaged by the forked end of a lever 43 which is journaled on a bracket 44 carried by the bracket or hanger 29. Each of the hangers or brackets 29 has a lug 45 projecting inwardly therefrom and another lug 46 extends outwardly from thelend of each sleeve 39. It will be obvious that by means of either lever 43, the sleeve 39 to which it is connected can be shifted so ,as to withdraw the pins 41 connected to said sleeve, out'` ofl engagement with the gear 31 and at the same time shift the lug 46 laterally so that, during the rotation of the sleeve 39, said lug will come againstand be -stopped by the lug 45.

Spaced brackets 47 are-connected to each of theJ sleeves 39,'-ffand from .each of v these 4bracketsfextendsfz'afresilientffinger 'or strip vsired to adjust the leg sections of the mattress relative to each' other both sections can be lowered by means of the worm 32 and the gear 31 While the pins 41 of both disks 4() are seated in the openings 38. After both leg sections have been lowered to the level at which it is desired to support one of the legs, they will be held by the worm 32 which, as before stated, is constantly in mesh with the gear 31. When it is desired to 'raise one of the leg sections, the sleeve 39 controlling the movement of the section that is to remain lowered, is shifted so as to be uncoupled from the gear 31. Said gear is then rotated and will rotate the other sleeve 39 so that the leg section controlled thereby will be elevated.

It will be seen that all of the movable sections are yieldingly supported by the operating strips or fingers, thereby adding greatly to the comfort of the user.

A bracket 51 can be fastened to one of the side rails 1 by means o-f a screw 52 extendingA through said side rail and,also through a clamping plate 53, the side rail being interposed between the bracket 51 and the plate 53 as shown particularly in figures 3 and 4. An arm 54 isV hingedly connected to the bracket 51 and has a socket 55 for the reception of -a ypin 56 on which may be mounted a socket member 57 provided at one end of an arm 58. This arm may be provided with a tray 59 or other suitable form of .attachment to be used by the patient and which can be easily brought to position over the mattress. When the tray is not in use the pin 56 and the parts carried thereby can be removed and the socket 554 can be swung laterally against the side rail 1.

What is claimed is:

l..
