Specification of Letters Patent.

Patented oct. s, 1907.

Application led March 25. 1907. Serial No. 364,325.

To all whom it 'may concem:

Be it nown that I, ANDREW G. Eno, a subject ofthe Emperor of Russia, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Hospital-Beds, of which the following is a specification. i

The main objects of this invention are to provide a hospital bed of generally improved construction; Avto provide a hospital bed having anladjustable head and back rest, and means whereby said head and back rest may be easily adjusted either by the patient himself or by an attendant; to provide animproved form of adjustable foot-board; and to provideimproved mechanism for lowering and raising a removable section of the mattress and simultaneously moving a receptacle into andout of position thereunder without disturbing the patient occupying the bed. These objects are accomplished by the construction shown in the accompanying drawings, in which: p

Figure'l is a longitudinal vertical section of a bed constructed according to this invention. Fig'. 2 isA a sectionalplan view on broken line 2-2 of Fig. 1. Fig. 3 is a broken-away side view, looking from the side which is at the top of Fig. 2. Fig. 4 is a broken-away end view of the drawer and adjacent-parts- Fig. 5 is a detail of'one oi the operating levers. Fig. 6 is a detail showing the method of detachably securing thef j foot-board. Fig. 7 is a detail, ona reduced scale, .of v v the link which connects the receptacle carrier with have more easy access tothe patient.

the pad support, showing also its detachable connec' end b'ars 7 and 6 at the top of the bedV posts provide supports from which curtains of net or other fabric may be hung to hide the patient from view or to protect him from flies and mosquitoes, or drafts of air.

The mattress is made preferably in three sections, 10, 11 and '12, supported by suitable springs 13. The main mattress section 1() is mounted in a box-like structure comprising a bottom 14, sides 16, and a lower end 17. The head mattress sectionis mounted in a similar box-like structure 18 having sides 19 separate from the side rails 3. These boxes are supported by `shoulders held bythe inner'sides of the rails 3. As -sh'own in Figs. 2 and 3, the'upper edges oi the rails 3,

land the sides 16 and 19,4 are covered by strips 22, jointed at the hinges 24 between the boxes.

Space is provided between the dread-boards 4 andr 20 to permit the box 18 to` be tilted up, for example, to the position shown by dotted lines. Means are provided by which either the patient or an attendant may raise or lower this box with its mattress 12. The first named means compriseka longitudinal bar 25, connecting the'middle points of the cross-bars 6, pulleys 26 supported by the bar 25, and a cord 27, connected to the box 18 at 28 and extending along said bar, 25. The end of the cord 27 is provided with a handle 29 whichmay lie on the bed within easy reach of the 25 is a handle 30, provided with a loop or eye 31. A row 'of projecting pins 32 on bar 25 maybe engaged by-the eye 31for securing the back rest in different positions of adjustment. If the patient is strong enough inI his arms he can, by pulling upon the cord, lift himself to a reclining or sitting position. The eye 31 may then be placed in engagement with whichever peg 32 will hold the parts in the desired position.

The attendant may conveniently adjust the tilting back-rest 18 by means of a lever 33 located at one side y patient. Secured to the cord at a point along the bar Y,

33 it will spring from onenotch to the next. To lower i the back-rest, the handle of the lever is pulled away from the face of the quadrant 37 and allowed to descend under the weight of the patient and back-rest.

38 is a foot-board, provided with two side pieces 39,

the bottoms of which rest upon metal plates 40 secured upon'the strips 22. Eachplate 40 is provided with a series of slots 41, and beneath each slot, arecess 42 is i cut into the wood, the recesses being made longer than the slots in one direction toward the foot o f the bed. Each of .the foot-board side pieces 39is provided with a ,hook-shaped engaging device 43. When these hooks areengaged with the complementary slots in the plates 40, the foot-board will `resist any outward pressure ex'- erted upo'n it by the feet and legs of the patient. The footboard isadjustable toward and from the foot o the bed, as the hooks will engage any opposite pair of the slots 41. This device willfbe highly appreciated by patients who are confined to the bed for any length of time, as it enables them to relieve cramps and restlessness of the legs and back by pushing the feet against the foot-board. i v J The removable mattress section 11, is made fast to its supporting springs, which are in turn secured to the hinged support l5. The support is secured to the section 1l is supported in its normal position by the engagement of the operating lever 47 with a stop 48 on the bed rail 3.

Mounted to slide longitudinally of the bed, beneath the bottom board 14, is a drawer or receptacle carrier 49, having rearward projections 50l at each side. Said drawer is U shaped in cross section, having out-turned flanges 52 slidably mounted in guides 53 which are se cured to the frame of the bed. Fitted within the drawer is a suitable receptacle 55, provided with a handle 56 by which it may be withdrawn, and with a spring catch 51 for securing it. The drawer is connected to the end of the support l5 by a link 57, preferably of resilient metal oi the form shown in Fig. 7i The middle part 58 of the link is hinged to the support l5 and the ends'59 are sprung into openings in the parts 50 of the drawer.

To remove the mattress section 11, the crank 47 is disengaged from its stop` 48 and turned in the direction of the arrow. The support l5 and mattress section 11 swing with the shaft 45 and thev link 57 pulls the drawer 49 toward a position under the opening 46. When the lever 47 is turned as far as it will go, the parts will be in the position shownl by dotted lines in Fig. -1. The

cushion l1 Will now be out of the way and the receptaele 55 will be directly under the opening in the inattress and its support. The operator turns the lever 47 in reverse direction to return the parts to this normal positions. The receptacle is preferably of such formy as to fit closely against the bottom 14 of the mattress support.

` The link 57 may be readily sprung out of engagement with the drawer so that the mattress section 11 may be withdrawn without shifting the drawer; This is particularly useful in cases wher-oa patient is too weak to move as it provides ventilation for his back and prevents bed sores.

What l claim as new and desire to secure by Letters Patent is:

In a hospital hed, the combination of a mnttress-suplml't jointed on :l transverse line intermediate of its ends, iheseetion at the head end being adapted to lie-tilted to sup port a patient in a reclining position, the foot section hnv- ANDREW (i. ELO. Witnesses Trium; LITZEN, E. A. RUMMLsn.
