OUT FOR INVALIDS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed April 17,1905. Serial No. 256,048.

Wabash avenue, in the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cote for Invalids, of which the following is a specification.

My invention relates to that class of cots specially designed for the use of sick persons.

The object of my invention is to provide a cot that is adjustable to the several positions adapted to meet the wants, ease, and convenience of the invalid; that can be adjusted so that the invalid is raised from the horizontal to the sitting position and back to the horizontal; that can be raised in a straight incline with the head or foot high or low, as desired; that can be raised at the head and the foot above the center; that can be raised at either end independent of the others that can be raised and lowered in the horizontal position, all changes being made without disturbing the occupant; that enables the occupant to' respond to natures requirements without inconvenience, and that can be taken apart and folded together for storage and transportatlon.

The manner in which I accomplish these objects is described in the following specification and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation showing the general construction and changes in position of the several parts of the cot. Fig. 2 is a cross-sectional view on the line 2 2, Fig. 1, showing the removable part of the mattress and its supporting-frame. Fig. 8 is a top view showing the construction of the frame and position of the brackets when raised and folded. Fig. 4 is a detail side view of the mechanism for raising and lowering the head of the bed. Fig. 5 is a detail view of the top of Fig. 4. Fig. 6 is a plan view of part of the cot looking upward underneath the cot. Fig. 7 is a cross-sectional view on the line 7 7, Fig. 1, showing the shaft and mechanism for raising and lowering the bed. Figs. 8 and 9 are detail views showing part of the bracket, barholder, and bar.

In the drawings, A-is the main part of the cot, supported on the legs A and having suitable cross-bars A to support a mattress. At the head of this frame and affixed thereto are two brackets A which arehinged at A and are thereby adaptedltolbe folded over upon the cot when not in use, as shown by the dotted lines in Figs. 3 and 7. The tops of these brackets extend forward over the cot when raised and have a series of bar-holders A and bars A, the bars being adjustably secured in said holders, as shown in Figs. 3, 7, S, and 9. These bars are arranged so the occupant of the cot can reach and grasp one or the other, and thereby change the posit ons of the body while in the recumbent positlon. Aflixed at the foot of the frame A are two vertical arms A having vertical slots A Above the frame A is a second frame B,

formed of two main parts B and B These parts are joined by hinged joints B and are provided with suitable cross-bars B The end of the part B is supported by a pair of racks B, which are pivotally attached to the frame B. These racks extend down outslde the frame A and are engaged and supported. by rollers B and by the gear-wheels The rollers are supported on suitable S DUCLb GELD- ings in the frame A, and the gears are affixed 011 the shaft B which extends through and is supported in the frame A, as shown 1n 1! 1g. 7. Between one of these gear-wheels and the frame A on the shaft B is a ratchet-wheel B engaged by a pawl B which is plvotally attached to the frame A. On the end of the shaft B is a crank B, by which the gears and racks are operated and the frame B raised and lowered. The ends O of the part B of the frame B are curved down, as shown 1n Fig. 1, and are provided with loose plvotal studs which extend through and slide freely in the slots A in the arms A These studs are adjustably secured to the arms A by suitable thumb-screws O.

Affixed to the part B of the frame B are two locking-plates O one on each side. Each of these plates is adapted to be engaged by a lock-pin G which is adapted to be inserted into suitable holes in the part B of the frame B. When these pins are inserted, the parts B and B are locked together as a solid frame and can then be raised horizontally or raised at either end to form a straight incline from head to foot or foot to head, the ends of the frame B when raised at the foot pivoting on the racks B and when raised at the head prvoting on the studs in the ends C.

On each side of the frame B are two hooks O, one on each side of the hinge-joint B. These hooks are adapted to beheld by staples O affixed to the frame A, and are adapted. to hold the part B or the part B when either 'Ioo part is raised at the head or foot above the hinged joint B When all hooks are released and the lock-pin C is removed, then both ends of the frame B can be raised abov the hinged joint B Attached to the under side of the frame A is a small drop-frame D, one end of which is secured by the hinges D to the frame A and is thereby adapted to be lowered at the free end down to the floor. This free end is provided with a hinged clasp D which is pierced with several holes D and is thus adapted to be engaged by a suitable staple D By this means the frame D can be slightly lowered, as shown in Fig. 2, or dropped to the floor. Supported on this frame in the mattress E is a removable part E, as shown in Figs. 2 and 3. By releasing the clasp D and lowering the frame D this part of the mattress can be removed and a suitable vessel inserted in its place for the convenience of the occupant of the cot. Around this aperture the mattress is protected by suitable waterproof material.

The frame B supports a suitable canvas E, which is secured to the sides and ends of said frame by suitable means. This canvas also has an aperture E corresponding with the aperture in the mattress. On this canvas the invalid lies With such bedding as may be required. When the body of the occupant is lying horizontally and the frame B is not raised, the weight is on the mattress.

Attached to the part B of the frame B are a series of holders F, adapted to support a series of hoops F, arranged to carry the weight of the bedcloth ng and prevent the bedclothes from touching the invalid.

When my improved cot is constructed as described, and illustrated in the several drawings, the frame B may be removed from the frame A and the parts B and B folded together, the racks B being withdrawn from engagement with the rollers B and gears B and placed along the sides of the part B. The brackets A may by the removalof the bars A be folded one over the other on the frame A and the legs A be closed up under the frame. With the parts so arranged the cot is adapted for storage and transportation. When in use, the several parts are adjusted as described, and shown in the several drawings. The brackets A are raised and fixed in position by the bars A". The mattress E is laid on the frame A with the movable part E adjusted over the frame D. The frame B is then laid on the mattress, the racks B inserted between the rollers B and gears B The ends C are then adjusted in the arms A and secured by the thumb screw C. The pins 0 are inserted in the part B of the frame B and into engagement with the locking-plates C The hooks C are fastened to the staples C in the frame A. Suitable bedding is placed on the canvas E on the frame wheels, a frame, B, formed of tWo B, and the cot is then ready 6f occupancy. The occupant, lying with the head between the brackets A can reach the bars A and use them for slightly changing the position of the body. The pins C and hooks C can be adjusted at pleasure and the positions of the frame B be changed by operating the crank B. To raise the foot, that part is lifted and the thumb-screws C adjusted. To adjust or remove the part E of the mattress E and to insert suitable vessels in its place, the clasp D is released and the frame D is lowered and raised and made secure. By the insertion of the pins C in part B of the frame B and releasing the hooks C the frame B can be raised horizontally or on an incline above the mattress and the mattress be then removed or supplemented with such padding or additional supports as the condition of the occupant may require.
