ASAHEL J. GOODVIN, OF BROOKLINE, MASSACHUSETTS.

COMBINATION INVALID BED AND CHAIR.

SPECIFICATION forming part of Letters Patent No. 453,236, dated June 2,1891.

Application filed Fehruary2'7, 1888. Serial No. 265,365. (No model.)

To all whom it may concern:

Be it known that I, AsAHEL J. GOODWIN, of Brookline, countyof Norfolk, and State of Massachusetts, have invented an Improvement in Combined Invalid Beds and Chairs, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts..

This invention relates to beds especially adapted for hospital and invalid purposes, and has for one of its objects to construct the bed, as will be described, whereby the ends of the said bed may be raised and lowered independently of each other, to thus enable the position of'the head and body of a patient or invalid supported by the bed to be changed without altering the position of the seat and legs of the patient, and vice versa.

Another feature of my invention consists in a stretcher to be used with the bed, so that the patient or invalid may be raised bodily up away from the bed.

My invention further consists in an independent seat portion having an adjustable foot-support connected thereto, the said seat portion being connected tothe mattress and normally resting thereon to form part thereof, but adapted to be raised up away from the mattress to raise the seat and legs of the patient orinvalid to obtain a different or easier position for the patient.

My invention still further consists in details of construction to be pointed out in the claims at the end of this specification.

Figure l is a top or plan View of an invalid-bed embodying my invention,the main or body portion of the stretcher being omitted to avoid confusion in the drawings; Fig. 2, a longitudinal vertical section of the bed shown in Fig. l, looking in the direction indicated by the arrow; Fig. 3, a longitudinal sectional detail of the front portion of the bed, showing the foot-rest in a lowered position; Fig. 3, a detail to be referred to; Fig. 4, a transverse section of Fig. 2 on linea oc to more clearly show the construction of the rack-bars; Figs. 5 and 5, details of one of the rack-bars; Fig. 6, a detail of the stretcher foot-rest; Fig. 7, a detail in elevation of the friction mechanism; Fig. 8, a section of Fig.

Referring to Figs. l and 2, the head-board A of the bed, having secured to it the sides A A2, provided with legs A3 at their opposite ends, is herein shown as made in two parts, as 2 3, united by hinges, as 4 the said parts being normally locked in their upright position by a rod a, (see Fig. 2,) secured at one end to a cross-bar am, and threaded at its other end, and inserted through a forked lug CL2 on a cross-bar @24, after which the rod receives a nut a.

The side boards A A2 have secured to them brackets or castings d3, (see Figs. .orL and 2,) each having a flange a* and gib (LX, made adj ustable, as shown, by set-screws d20, the said iian ge and gib constituting guides for a rackbar or brace- Each racI-bar, as herein shown, is slotted at its lower end (see Figs. et and 5) to form ears a7, which embrace a crossbar a9, as show-n in Fig. 4, each rack-bar being kept seated on the bar 0.9 by a pin as, the said pin forming, as it were, a pivotal connection between the said cross-bar and rackbar. Each rack-bar ctis provided with a web or iiange ctw, having a foot am, which is also slotted to lit over and engage the edge of the said cross-bar a, the said foot being also tapped and threaded to receive an adjustingscrew als, by which the rack-bar may be turned on the stud as as a pivot, to thereby move the upper end of the rack-bar outward, the said IOO rack-bars forming adjustable braces to support a stretcher-frame, to be described. The rack bars or braces a5 have their upper ends fitted into and firmly secured to brackets or castings Z), fastened to the side bars or rails b of What is denominated a stretcher-frame, the said brackets or castings being located, substantially as shown, upon the said bars or rails, so that when the rack-bars are moved vertically, as will be described, the stretcherframe will also be moved bodily up or down.

The side bars or rails b of the stretcherframe are provided at their ends, near the head-boards, with castings b2 b3, (see Figs. l, 13, and 14,) each casting preferably having secured to its inner face a layer b4 of felt or other material to prevent marring or injury to the Wood- Work outside of it when the stretcher-frame is moved up and down by the rack-bars.

The side bars of the stretcher-frame, near the head of the bed, are united, preferably, by a cross-bar b5, having at its opposite ends castings provided with lugs b, preferably elongated, as shown in Figs. 14 and 15. The casting b2 (shown separately in Fig. 15 and having an elongated slot, as bx) is entered by one of the lugs, and thereafter the barl is given a quarter-turn, so that the lug h6 stands with its longest portion across the said slot bx, and then the lug h6 at the opposite end of the said bar b5 is made to enter the opening in the casting b3 and pass therein beyond the end of a locking device bl, (shown in Figs. 13 and 14: as a spring,) the latter holding the bar in place.

Each side rail b has secured to it, preferably near the longitudinal center of the bed, a boss Z210, (sce Fig. 2,) forming a bearing for astud on the ends of a substantially 1-shaped bar bla, of a length substantially equal to the distance between the said bosses and the head-board. The |shaped bar Z213 in practice \vill be covered With canvas or oth er snitable or textile material b2", the said bar and covering forming part of the stretcher and constituting a movable support for the body and head of the patient.

The body-supporting frame has its free end sustained, as shown, by the cross-bar b5, so that when the stretcher is raised bodily through the rack-bars the head of the patient is raised at the same time as the body-that is, the entire body of the patient is raised at one time.

The side rails b have secured to them the foot-supporting portion of the stretcher, (see Figs.2 and 6,) it consisting of a substantially U-shaped frame b1, covered with canvas or other suitable material, as 1725, the said frame being secured to the side rails, as shown, by castings 1115, fastened to the ends of the frame and having arms 616,(see Figs. 2 and 6,) shaped substantially, as best shown in Fig. 6, to enable the said arms to be slid under and so as to engage the upper and lower sides or edges of the side bars b of the stretcher-frame, the

main casting 7W resting upon the top of the side bar or a rail thereon. This construction enables the foot portion of the stretcher to be readily removed and put on, as desired.

The casting bis is preferably lined with felt or other material to prevent marring of or injury to the side bars. I do not desire to limit my invention to the exact form of casting Z115 shown in Fig. G, but may use any wellknown equivalcntshaped clasping device rigid yet readily detachable from the side bars.

The portion of the stretcher between the foot and back supporting sections will preferably be composed of a number' of strips c of canvas or other material, (see Fig. 12,) the said strips being extended through slots c in the side rails and lirmly secured in place, as shown, by buckles c2, herein shown as a plate of metal secured to the side bars preferably by staples c3, (see Figs. 1l and 12,) the said plate having teeth c4 to engage the strips of canvas or other material. The inner side of the top rail of the stretcher-frame is grooved or channeled at CX, as shown in Fig. 12, so that as the buckle c2 is moved into its upright position substantially parallel to the side rail t-he teeth c4 are made to enter farther into the material, thus obtaining a sure and reliable fastener for the said strip.

The rack bars or braces are engaged by pinions 25, only one being shown in Fig. 2, on a shaft 26, having mounted thereon a gear 27 in mesh with a pinion 28 on a hub or hollow shaft having mounted thereon a disk 29, comprising part of a friction mechanism to be hereinafter more fully described in connection with the head-section of the bed, Where like devices, but designated by different letters, are employed to adjust and hold the toothed sector cl2.

The sides A A2 have pivotally secured to them a mattress-supporting frame composed of a head and a foot section.

The head section is herein shown as a substantially 1-shaped frame c5, having at its ends a sleeve or hub to engage a stud c on the casting a3, (see Fig. 2), and secured thereto, as shown, by a washer c7,riveted thereon. Each arm of the L ]-shaped frame c5 comprising the head-section is provided, as shown,.

with a stud or roller es, extended into the slot 09 of an arm C10, forming part of a toothed sector om, mounted on a stud or arbor c13 of a casting c, secured to the sides A A2. sector c12 meshes with and is driven by a pinion d on a shaft d', having mounted thereon a gear d2 in mesh with a pinion d3 on a hollow shaft d" having secured thereto or forming part thereof, as shown, a friction-disk d5, (see Figs. 2, 7, and 8,) the said hollow shaft being supported in bearings d, forming part of a casting dx, secured to one side board, as A2. The friction-disk d5 has co-operating With it spring-arms d? d8, provided with suitable friction-surfaces dg, to bear against the disk (Z5, the said disk and spring-arm consti- IOO IIO

The

into a threaded socket d11 in the casting CZX.

The spring-arm d8 bears against the casting (ZX and the spring-arm d1 against the head of the bolt 13, so that by turning the said bolt the amount of friction between the springarms and disk may be varied, as desired.

The foot-section of the bed is composed as herein shownv of a substantially I I-Shaped frame e, preferably of sheetsteel of angle form, the bent corners of the I l-shaped frame being provided with braces e to unite the sides or arms e2 to the main or cross piece of the frame. (See Fig. 18.) Each arm e2 has secured to it, byrivets or otherwise, a sectorgear e5, (see Figs. 2 and 3,) havinga cam-surface, as et, Withwhich co-operates a roller e5, fastened to abending-bar e6, to be described. Each sector-gear e3 is driven by a pinion e7 on a shaft e8, having mounted thereon at one end, as shown, a gear e9 in mesh with a pinion @10 on a hollow shaft or hub 612, provided with a friction-disk @13, the said friction-disk being` engaged by spring-arms 611 in a similar manner to that described with the frictiondisk d5 of the head-section. The arms e2 of the frame composing part of the foot-section at their ends opposite to the sector-gears are engaged by channel-bars f, (see Fig. 16,)

which are adapted to slide over the said arms to extend or lengthen the foot-section, as will be described. Each channel-bar f, as shown in Fig. 17 on an venlarged scale, has a stud f', which is engaged by one of a series of holes fx (see Fig. 16) in a lever f2, pivoted at f2() (see Fig. 3) to the sides A A2, the said lever being secured to the channel-bar, as shown,

by a spring-catch f3, shown as a flat spring pivotally secured to the channel-bar by screw f4, and having a stud or projection f5 to enter a socket or recess inA the stud f. The channel-bars f sustain the foot-rest, consisting of arms f6 and foot-board f1, supported thereby, (see Figs. 2 and 16,) the said arms being pivoted to the said channel-bars, as at f8, and provided with notches ff fw, (see dotted lines, Fig. 16,) to co-operate with studs f12 f13 on the channel-bar to form stops by which the backward or outward movement of the foot-rest is limited. The foot-rest is retained in its normal position, as shown by full lines, Fig. 16, by a catch or locking device, shown as a spring f14, pivoted toone of the arms f6,

and having a pin or stud f15 to enter holes in the said arm and channel-bar. The foot-rest is turned into its dotted-line position, Fig..l6, when not in use, and it is locked in its dotted-line position by the stud f15 on the spring f14 entering a second hole in the channel-bar.

As shown in Figs. 3 and 16, the last hole f in,

f on the channel-bar, thus bringing the footrest in its farthest position from the bed. To shorten or bring the foot-rest nearer the bed, the stud f5 is disengaged from the socket in the end of the stud f', and the channel-bars f moved up on the arms e2 and another hole fx engaged with the stud f.

The head and foot rest sections sustain the suspension-mattress, composed, preferably, of end springs g and links g', secured to plates or disks g2. Near the longitudinal center of the mattress and ou opposite sides thereof two links, as t, (see Fig. 1,) are made, as herein shown, of considerable thickness to obtain strength, each link being provided, as shown, with a stud t to which the hair or other mattress (not shown) is secured. The plates or disks g2, substantially in line with the pivots c7 of the head-section, are joined by stays or chains g3 (see Fig. 2) to a cross-bar g1, secured, as shown, to the casting 011. Two links t2 t2, also in line across the mattress and adjacent tothe bars t t, are made stronger, and are provided outside the mattress With studs 7 8, upon which are fitted the slotted ends of side bars g5, extended toward the foot of the bed and joined at their ends by a shaft or rod g, having bearings in the said side bars. The shaft or rod gG and side bars g5 form a supportingframe for an auxiliary seat, composed, as shown, of strips or slats Q7, preferably of sheet metal, having one endbent around the shaft or rod g6 `and the other end engaging the bars IOO t2 and links in line therewith; but, if desired,

-bar g8 are detachably connected tothe side bar g5 by levers Q13, pivoted to said arms and adapted to engage the studs 9. The shaft Q12 is preferably provided at one end with a pinion or ratchet 7o, normally engaged by a Weighted orgravitating pawl 7c', (see Figs. 2, 3, 9, and 10,) having a spring arm or extension k2, preferably of sheet-steel, the said spring-arm being engaged by a stud k3 on a friction-lever IIO 761, pivoted to one of the side boards, as A2.

Normally the pawl k" is in engagement with the ratchet c, as shown'in Figs. 2 and 3, and the friction-lever k1 will be in the dotted-line position shown in Fig. 3; but if it is desired to disengage the pawl from the ratchet the friction-lever k1 will be turned into the position shown by full lines in Figs. 2 and 3, the said lever then exerting a pressure on the spring arm or extension k2, so that when the shaft Q12 is turned but very little, or a sufficient distance to disengage the pawl, the said spring-arm will act to throw the paw'lout of ISO engagement with the ratchet, thus permitting the shaft to be rotated in either direction.

' In most cases I prefer to employ a friction mechanism comprising a disk and springarms, as described; but in every ease where I have herein shown and described such a friction device I may employ therewith, if desired, the pawl and spring-extension actuated by the friction-lever, it being especially applicable to the center and seat portion when the invalid is a heavy person and the attendant of but medium or little strength, the said parts being readily applied to and detached from the bed. The shaft or rod g6 has mounted on it a foot-supporting frame or leg rest composed of sides r and a cross-bar r', the said sides having secured to them, as shown, hubs r2, (see Fig. 22,) through which the shaft or rod gG is extended. The shaft or rod g* has secured to it at one end beyond. the side bar g5 a ratchet-wheel Ir3, engaged by a pawl r1, pivoted to the side bar g, the said pawl being normally held in engagement with the said ratchet by a friction-lever T5, pivotcd to the side bar g5, the said pawl and frictionlever normally occupying the full-line position shown in Fig. 20. The friction-lever is shown as provided with a V-shaped end, which forms two ears or flanges r6 r?, extended with relation to the length of the said lever, one ear, as fr?, acting on one side of a beveled arm rs of the pawl to keep the said pawl in engagement with the ratchet, as shown by full lines, Fig. 20. )Vhen it is desired to release the pawl r4 from the ratchet the friction-lever is turned on its pivot to bring the ear r6 in engagement with the arm rs of the pawl, so that when the leg-rest is lifted a very little the ear r6 will slip down the beveled or V- shaped arm of the pawl and turn the said pawl into its dotted-line position, out of engagement with the ratchet, thus permitting the leg-rest to be moved readily in either direction.

The ratchet and pawl and friction-lever fri constitute a locking device for the foot-supporting frame.

In practice the foot-supporting frame or leg-rest will preferably be equal to substantially one-half the width of the seat, so that in case of injury to one leg of a patient, the said injured leg may be supported in any desired or comfortable position upon the legrest, while the well leg of the patient may hang over the shaft gi'. This is especially true when the seat and leg-rest are raised into substantially the position shown in Fig. 2, and the head-section has been raised substantially into the dotted-line position Fig. 2, the said seat and head sections, when in the positions described, forming a chair.

As shown in Fig. l, the foot-supporting frame or leg-rest is in position to receive the right leg; but, if desired, the said frame may be moved to receive the left leg, the shaft g6 being first unelamped from one of the side bars g5 and the slats Q7 disengaged from the said shafts, and then engaged again when the supporting-frame has been moved into position. The bending-bar e5 (see Fig. 2) is provided at its ends with arms s, supporting rollers c5, which rest upon and ride over cam-surfaces e"l of the segments c3, before described, the said cam-surfaces being so shaped that the bending-bar, is in its lowest position (shown in Fig. 2,) when the foot-supporting frame is in its highest position, and vice versa, as shown in Fig. 3. The longitudinal links forming that portion of the Wire mattress immediately above the bending-bar are replaced by short chains s', which enable the mattress to be bent over the bending-bar when the foot portion is lowered into the position shown in Fig. 3.

In practice the head-section may be raised from its full to its dotted line position, and vice versa, from the side of the bed by means of a crank not shown, but which is applied to the hollow shaft or hub d", and the foot-section may be turned in a like manner from the position shown in Fig. 2 to that shown in Fig. l, and vice versa, and the seat portion may be raised and lowered by turning the shaft 912. When the foot-section is raised from the position shown in Fig. 3 to that shown in Fig. 2, the channel-bars f will be moved outwardly by the levers f2 to lengthen the said footsect-ion, and the foot-rest will be brought toward or nearer to the bed when the said footsection is moved into the position shown in Fig. 3.

My improved invalid-bed may be transformed into a chair by moving the head-section into it-s dotted-line position, Fig. 2, and the foot-rest and section into substantially the position shown in Fig. 3, the auxiliary seat being in its lowest position-that is, resting on the mattress-or the said bed may be transformed into a reclining-chair by raising the auxiliary seat into the position shown in Fig. 2, the head-section being in its dottedline position.

\Vhen it is desired to employ the stretcher to raise the patient up from the bed to enable the latter to be made or for other purpose, the strips c, comprising the seat portion of the said stretcher, may be first passed under the patient and secured to the side rails. The patient may then be raised into a sitting posture to enable the back-supporting frame to be secured in place, its end resting, as shown, on the cross-bar b5. The stretcherframe is now raised through the rack-bars a5 by rotating the pinion 28 by the crank referred to. It will be noticed that as the stretcher-frame is raised the patient is lifted bodily at one time. The body-supporting section of the stretcher may be inclined by raising the head-section of the bed until it forms a bearing against the under side of the said body-supporting section, (indicated by dotted lines, Fig. 2.)

To facilitate shipping, the part 2 of the headboard may be folded down over the beck-that IIO IIS

is, substantially at right angles to the part 3-- and the foot-rest turned into its dotted-line position shown in Fig. 16. By means of the adj Listing-screws L13 the rack-bars may be turned on the stud as as a pivot, and their upper ends moved outward to take up any spring in the bar a and maintain the side rails of the stretcher-frame rigid and the material comprising the stretcher taut when the s aid stretcher is used to sustain a substantiallyheavy person, thus obviating any conJ slderable sagging of the stretcher.

I do not herein claim, broadly, a pivoted leg-support and sliding foot-rest connected to aframe, as the same forms the subject-matter of another application, Serial No. 311,305, tiled by me May 1S, 1889. It is obvious that when the head-section is elevated and the foot-section lowered the bed constitutes an invalidchair.

The sliding foot-rest herein shown and described is not herein claimed broadly, as it forms a subject-matter of another applicatlon, Serial No. 311,305, filed May 18, 1889.
