ARTHUR SKEFFINGTON, OF LONDON, ENGLAND.

INVALID-BED.

Specification of Letters Patent.

Patented Oct. 8,1912.

Application iiled August 24, 1911. Serial No. 645,837.

To all whom it may concern:

Be it known that I, ARTHUR SirnrriNo- TON, a subject of the King of-England, residing at Blackheath, London, England, have invented certain new and useful Improvements in Invalid-Beds, of which the following is a specification..

My invention relates to an improved invalid bed, in which a mattress composed of transverse "sections, certain of which sections comprise a series of longitudinal units, is supported by a main frame to permit. ready interchange of' said several mattress sections and independent lowering of said longitudinal units.

My invention relates further to an improved invalid bed, in which the transverse mattress sections can be lowered from the main frame, and said frame shifted and locked in different positions.

In theaccompanying drawings :#Figure l is a perspective View of a frame with a sectional mattress constructed according to this invention; Fig. 2 is a fragmentary sectional view on the line 2--2 of Fig. l; Fig. 3 is a plan of a detail of Fig. l, and Fig. 4 is a perspective view showing a modified form of the apparatus.

Like letters indicate like parts throughout the drawings.

The main frame A may be of an le iron of L shaped cross-section, the foot o the L being turned inward to form a horizontal ledge A1 as shown at the left-hand end of Fig. l where part is broken away to illustrate it and in plan in Fig. 3. The frame may lie on a bedstead or b e otherwise su ported as found convenient. Free to sli e on the ledge A1 is an auxiliary frame B which may be similarly constructed of angle iron. rllhe frame B in the drawing is shown in the middle position on the frame A and on each side of itl are transverse mattress sections C. These may be supported by boards C1 bridged across the open space between the longitudinal members of the frame A and resting on the ledge A1. The auxiliary transverse frame B carries a trans- 'verse mattress section comprising a series of ndent longitudinal units B1 supported ongitudinaly-extending boards B1*.

inde by ,One of said boards is shown hinged to the transverse frame B at B2' for downward swing; a suitable latch Ba bein provided on said fra-me for locking sai board in position.

` fastenings F1.

Vith the frame a lifting apparatus (Fig. 4) is illustrated as applied to a bedstead and comprises a roller D mounted in bearings on each end of the bed and operated by worin gearing E. The roller is normally employed for operating a long sheet and the frame fast on the roller spindle. The cables travei'se the length of the frame and pass over 'loose'pulleys Ds at the other end of the `bedstead being guided by intermediate pulleys D1 and secured to the mattress suplporting frame at D. Instead of this, liowever, the roller itself may be employed for lifting by attaching a short portion of sheeting F to the roller D", its free end being connected to the frame by chain or other A second roller would then be employed at the opposite end of the bedstead and a short sheet portion similar to the portion F used to connect the roller at that end of the bedstead with the corresponding end of thc mattress frame; thus by operating the two rollers the whole frame withv the sectional mattress and the patient thereon can be lifted. IStuds Fzare shown at the left-hand end of the frame, Fig. l, to receive the chain connections to the sheet. In the known form of apparatus the rollers are for operating a long sheet and thus by using sheet portions F to lift the frame, only one kind of connection need be employed for the roller so that any person can' readily connect these two sheet portions for lifting the frame.

The operation of this apparatus is as follows The mattress sections are so arranged that a atient who perhaps has some spinal complaint necessitating constant dressing of the back, can be so placed that one of the independent longitudinal mattress units will be positioned opposite the part requiring dressing. The requisite adjustment of the portion can be effected by putting a greater or smaller number of undivided sections at one end of the frame than the other and without inconvenience. A cor B* may :is lifted by cables D1 secured to pulleys D2` The swinging longitudinal mattress unit is preferably secured to its su porting board so that it does not .come -a ift when the board is moved. The board may be hinged at one side instead of one end.

In a modified form of this invention shown in Fig. 4, the transverse mattress sec- 5 tion G'4 is supported in a well known manner by 'bands or straps G1 which are fixed by buckle fastenings to the longitudinal members of a frame II. Thus by unfastenin the buckled ends fromv one lon 'tudin'a member the section can be droppe swing' ikrlig about the other member, or by -unbuc- 1n In t is gure the auxiliary frame J for the longitudinal mattress units J1 is carried by hangers J2 that rest on the longitudinal members ofthe frame H and can be slid along the same or lifted therefrom.

1What I claim as my invention and desire to secure by Letters Patent is 1. In an invalid bed, the. combination oit' i a sectional mattress, a main vframe supportboth ends the section can be removed. f

it norma y up in Loeof/ee ing the sections of the mattress, a frame slidable on th'e main frame and carrying sections o the mattress whose divisions are parallel with the longitudinal axis of the bed, and means for lowering one of these sections without disturbing any other section.

2. In an invalid bed the combination of a sectional mattress, a main frame supporting the sections of the mattress, a frame carrying sections of the mattress whose divisions are parallel with the lon itudinal axis of the bed, and slidable on t e main frame to be interchangeable in position with other sections of the mattress.

8. In an invalid bed the combination of 1a sectional mattress, a main frame supportf ing the sections ofthe mattress, a frame slldable on the main frame and carrying sections l of the mattress whose divisions are parallel rwith. the longitudinal axis ofv the bed, a

4hinged support on said slidable'frame for one of said sections whereby the latter can be swun downward, and means for holding osition. In testimony w ereof I have signed my name to this specification in thepresence of two subscribing wltnesses.
