Serial No. 565,899. (IfTo-model.)

To collwhom it may concern: Be it known that we, EDWARD CHARLES zens of-the United-States, residing atSacra: mento, county of 'Sacran1ento,State of Cali-1 fornia,-have invented an improvement inInvalids Beds; and .we hereby declare the (fol-i tion of the same. Our invention relates totthe class of beds for, themattress or mattresses, andthe novel; detachable and adjustable connections jbewhich we shall hereinafter fully describe.

The object of our inventionis toprovidea ver'sa, andthe mattress on whichhehad been lying .removed upon the substitution of *anposition, thus not only relieving theinvalid by achange of position but affording oppor- Referring .to 11 the accompanying drawings,

A are circular ends of the bed-fra1ne. These, restand are turnableupon rollers Z; in brackets Bonthefloor.

O are the side rails or "bars, two on each side, one above and one'below. They are connected withthe circular ends insnitable manner; but thebest connection is an adjustable one, in. order to vary their. separation to suit different patients. The adjustable 00111160 otedor swinging ratchet-bars a, whichen- 5o gagethem.

Inordertohold the turnable frame steady upon its supporting-rollers,there is attached to each. side'of one end Aa leg 'D,iwhich is a peculiarly adjustable one, inorder toadapt it tomove out of the way topermit the bed to rotate and to fallagaintoposition for use. The upper end d of the leg is bent inwardly and an elongated slot (1 is made in the upper portion of said leg and extends also intothe .60 bent end d. A pin or stud a on the end of a cross-piece a on the circular end A normally fitsin the extremity of the slot d in the ibent end, and thusjthe leg is .held and serves 1 asva support; but uponmoving the leg in wardly so that \itslipsits slot along the pin or stud (L2 to itsbend the circular end can; then .rotate,-as.its pin or studwill travel downthe lengthiof the slot d nearly to its bottom, and then, upon reaching .thenprising-side ofits 7o rotation, .the pin or stud will travel up again in the slot and will reachjits upper extremity and carry the legrup with itto a stable position onthe other side, in Whichit will again serveasia support. During this movement (the opposite leghas been simply bodily carriednp andoverby the turning end A,as it only requires thattheileg on the side toward which the turn ismade shall (be disposed of to permit the turntobe made.

E is -a mattress, and F is the frame to which it is attached. At one end the frame has small wheels G, upon which it can be rolled in order to transfer it easily from place to place.

Let. into orformed with the side bars of the mattress-frame. is a vertically-disposed socket or. sleeve 'H, there being-four of these, one at p or near each end of each sidebar. The lower end of eachsocket or sleeve is formed orproo vided with a ratchet-clutch h, and around it j ustabove the clutch isa series of radiall }proj ecting pins 1h. In each socketror sleeve is fitted the shank "i of aisuspending or hanger screw I. This screwis, formed of two spirally-directed bars, the course. of which is similartothat ofa duplex thread. The separation between them i is sufficient to permit the. passage of a bar having the diameter of the side rails C of the bed-frame, and one of said spiral bars is made longer than the other, for a purpose we shall presently describe.

Supported upon a nut i on the lower end of the screw-shank I; is a ratchet-clutch i adapted to engage the clutch 7L, and when so engaged to prevent the hanger-screw I from turning. The clutch i is recessed on its upper surface, and in the cavity thus formed lies the head j of the lever J, which extends outwardly through a groove i in the side of the clutch. Lying in this same cavity is the head of a second lever K, which is so bent as to be able to fulcrum on lever J, and thereby to lift its head when said lever is pressed down upon. Both lever-heads slide freely upon shank i, and normally lie well within the cavity or recess of clutch '6 so that they do not interfere with the engagement of said clutch with clutch h; but when said levers are pressed together, the heads separating and bearing in opposite directions against the clutches separate them and break their engagement.

L is a second mattress having a frame with wheels and sockets or sleeves and hangerscrews and attached parts precisely like those of mattress E. This mattress L, being intended to support the patient upon his face, is shaped, as shown, to give him the comfort of disposing of his arms about the neck Z, supporting his shoulders on the wide portion Z and his face on the head-piece Z M is a board, which by means of a bracket m, to which it is secured, and an adjustable clamp m is secured to the side rails O in a position to act as a stop for the patient when being turned with the bed.

The operation of the bed is as follows: Let it be supposed that it is yet without an occupant. One of the mattresses, say E, is then rolled along on the wheeled end of its frame until it is alongside of the bed-frame, whereupon it is set on its side edge. Then one end is raised until the hanger-screw at the side of said end is in position to hook the longer end of one of its screw-bars over the side rail G. Then the other end is lifted and its hanger-screw is hooked over the same side rail. Then the mattress is laid over flatwise on top of the bed-frame and its hanger-screws on the other edge engage the opposite side rail G. The hanger-screws being thus fitted and started rotate under the weight of the mattress and screw themselves down to their bases over the side rails. Now that leg D, which is on the side to which the bed is to be turned, is manipulated, as heretofore described, in order to get it out of the way, and thereupon the whole bed is invertibly rotated through a half-turn 011 its rollers b. As soon as the mattress reaches its new and reversed position, its weight causes the engagement of the clutches h and i and these prevent the hanger-screw from turning, and consequently they suspend the mattress from the lower side rails O. The patient is now placed in the bed. To change him the mattress L is rolled into position and is adjusted to the top side rails Gin the manner described in regard to mattress E and directly over the patient. The board M is now placed in position and the device rotatedas before, the patient remaining between the two mattresses.

\Vhen mattress L is down and mattress E is up, the patient is lying on the former face down. Mattress E is now removed by a process the reverse of that by which it is applied. When called into use again it is replaced and the patient turned with it and then mattress L is removed. To remove the patient readily the levers J and Ken one side are pressed together and the clutches 7t and t disengaged, whereupon the hanger-screws rotate and allow that side of the mattress to come down to the floor. Then by relieving the bed-frame of its leg D said frame will turn by reason of the weight and thus allow the other side of the mattress to come down to the floor. The object of the pins it around clutch his to provide by successive engagement with lever K, at the will of the operator, a check upon the turning of the hanger-screw and the descent of the mattress.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is
