To all whom-tt may concern: f

Be it known that I, AIKEN C. TAYLOR, a citlzen of the United States, residing at Richmond in the county of Henrico and Vlrginia, have invented certainAImvprovements 1n Invalid-Beds, of whichl the State of following is a complete specification. 4

This invention is an improvement in beds, and relates more especially to that particular class which are commonly known as invalid beds, and in which the 'mattress support is so constructed as. to be adjustable for the purpose of moving the patient so that his body maybe disposed in different positions.

The present lnvention contemplates a peculiar constructionof invalid bed apparatus embodying a mattress support composed of three hingedly connected sections, in combination with a particular form of bed frame supportingthey sections and means for adjusting sald sections relatively to each other,

' the mattress will be inclined upward. Fig. 3

whereby they may be easily and conveniently adjusted by one person so that the body of lthe patient may assume a number of different positions from a reclining to a sitting position, and when' adjusted forthe latter purpose'the sections are arranged after the manner 'of an ordinary easy-chair, in which the lowered foot-section is unobstructed so as to permit the patient to lget in. and out of the ap aratus. l

The invention is especially serviceable for hospital purposes, but as will be readily obvious may be used in a private home and in the capacity of a conventional bed when desired. A, j

The invention consists in the novel con-4 struction and arrangement of parts constituting the invalid bed apparatus, all as hereinafter fully described land specifically set forth in the appended claims. Y

ln the accompanying drawings, which form a part of this s ecication': Figure 1 is a perspective view o an invalid bed appa-` ratus constructed inv accordance with my 1nvention, the parts being arranged to supportV the mattress in a horizontal position similar to an ordinary bed, Fi 2 is a side elevation, with the foot section of the mattress support elevated so that the lower end of is a side elevation, with the sections of the mattress support arranged in the form of a chair. Figgfl is a vertical sectlonal View on the line 4-4 of Fig. 3, looking in the direction of the arrow.

Like numerals of reference indicate like parts in all the figures of the drawings,"

- In carrying out niy invention the principal parts of the apparatus, are constructed of 'metal bars so shaped and connected as to provide an invalid bed that it is notonly light in weight but is alsostrong and durable and therefore serviceable in use.

Referring to the drawings it will be seen Vthat the bed frame consists of a metal head section 1, of conventional design, to lthe end posts of Which-are secured'by metal brackets 2,"the side rails 3,v the latter being bent downwardly at their outer ends to -form posts 4 which constitute the support for f the foot portion of the bed. The side rails are .connected near the head section 1 by means of a cross-bar '5, and near the supporting-legs or posts 4 by cross-bars 6 6, the latter serving as braces for the bed-frame and also to support a horizontal cross-piece or board 7 ,the purpose of which will be hereinafter explained. l v

Secured tothe bedv frame by means of the cross-bars 6, and extending parallel with'the side rails 3, are bars 8 8, which in connection with the plate or board 7 forms thev which the head and foot sections of said support are hingedly connect-ed. The head section of the mattress support is composed ot' side bars 9 9, hinged lat one end to the-bars S bya connecting-rod 10, and attheir other or freeend 'curved slightly upward, as shown, andv connected together by .cross-bars or connecting-rods 11. The foot section of the 'mattress support is similar to the head section thereof, with-the exception that the side-bars 12 12 are extended upwardly so that in connection with the j cross-bars 13 there is formed a suitable foot portion when the parts are arranged as a bed (Fig. 1), and a support for a foot rest when the parts are arranged as a chair (Fig. .3). Connected to the head and foot sections of the mattress support is an ordinary form of wire mattress 14, of woven-wire construction and oonnected at its ends to said sections by means ofvcoiled sprin s 15, the springs at one end being connecte to the cross-bar or connecting-rod 11 ofthe head section, while the` springs 'atthe other end are connected to one ofthe crossbars or connecting-rods 13 of the foot section, vand at anintermediate point, preferably at the. inner end of the late or board 7 said wire-mattress-is reinorced by meansv of spiral springs 16. The hair mattress, or pad, as 17, is placed dirljectly upon this Awire mattress, as shown in A will be seen the head and foot sections ofthe mattress supporting frame are hinged vao to the stationary center section so that the former may 'swing vertically and assume different pos1tion s, andfor the purpose of ad- .justing these:I hinged sect-ions I provide cer-v tain mechanism which I shall now proceed to describe. I

Hinged to the free end ofthe head-section of the mattress supporting frame, by means of one of-the connecting-rods llthereof, are links' 1818, and connected to these links and to the foot-section are connecting bars 19 19, whereby said head and foot sections may be moved simultaneously. The connection between the bars19 and links 18 is by means of a rod 20 theends of which ass throu h j holes in the bar-sand, through s ots 21 in t e links, the projecting" ends of said rod being threaded to receive clamping-nuts 20a. By

this arrangement the head section of the mattress supporting frame may be adjusted independently when desired, as `hereinafter explained.

` 22,22 designate levers which are pivotally `connected at their upper ends to the side rails of the bed frame, respectively, and at their lower ends tothe connecting-bars 19 19 at an intermediate portion thereof, the connection with the bars 19 being by means of a cross-rod 23. In this manner the operatin devlces for the adjustment of the hing head and foot sections of the mattress supporting frame are connected so that" they may be operated by moving one of the levers 2 2. These levers are pre 'erabl pivoted at their up er ends between the si e rails 3 and the side ars 8.

Located at one si-de of the bed frame, and securedat its ends between the'side rail 3 and'side'bar 8 is ,a semi-annular plate 24,

l, having rack-teeth 25 at its inner edge, and a 'series of holes. 26 extending transversely v in an adjusted position. rlhis lever .carries a pinion or spur-wheel 29, in mesh with the rack-teeth 25, and the gudgeon 30 of said p1 n1on -1s extended beyond the lever and is squared to receive a removable crank-handle 31. As will be seen the lever 22 is moved in either direetionbysimply turning the crankclination.

essaies will operate the head and foot sections of the 'mattress supporting frame.

The head section of the mattress supporting frame when lowered rests upon the crossbar 5 of the bed-frame, and when in this position the foot section may be raised independently by first releasing the clamping nuts 20a so that the rod 20 may slide in the slots of the links 18, and then operating the lever 22 so as to move the connecting-bars 19 to the right, the parts then assuming the position shown in Iig. 2. Conversely, the head section can be raised independent of the foot section by simply loosening the clamping-nuts and raising said head section to the desired extent, after which it can be held in elevated position by simply tightening the nuts; or said head section may be raised by means of the lever by first moving the foot section to the position shown in Fig. 2, and after tightening the clamping-nuts to secure the bars 19 to the links 18, move the lever to the left, which operation will lower the foot section to lhorizontal position andraise the head section to,- an upward inranged in theform of a chair (see Fig. 3), 'and in this operation the lever 22 is swung to the limit of its movement to the left, and held by the pin 28, the foot section being lowered substantially on a line with thelegs 4 of the bed-frame and just beyond the same, while the head-section extends in an upward inclination from the rear end of the stationary center-section; and in this posi- `with two of the cross-bars 13 of the footsection. I also provide the bed-frame with a removable or. sliding drawer 33, and with a small table or support 34 in connection with a larger table or board 35. These tables or supports are separable, so that the smaller one may be used alone asa holder for a glass of water, or other small article, and so that said smaller table or support may be swung out ofthe wa when not in use the standard 34 1s roun at its lower end and larger table or board may be securely held 1n its position transversely across the apparatus thestandard 35 is squared at its lower The sections may also be arn D n lits ma corresponding socket 36 1n the bedframe. 0n the other hand, in order that the end and fits in ay corresponding socket 37 at the other side of the bed-frame from lthe socket 36; and when in position the largerv table or board rests upon the smaller table for support, as shown in Fig. 4.

It Will be noted that `when the parts of the apparatus are arranged in the form of a bed the foot section of the mattress support extends vbeyond the posts or ylegs 4at the foot of theloed-fralueA 'and'forms theffoot portion of the bedtso vthat WhensaidV footsection of the mattresssupporting 4frame is llowered in arranging the.. apparatus. in the form of a chair, thusforming the foot-rest of the chair, there willf'be a-n unobstructed passage or Way around said foot-portion so that the patient may easily and conveniently get into andeutet the chair.. i
