SPECIFICATION forming part of Letters Patent No. 360,764, dated April 5, 1887.

Application filed January 26, 1886. SerialNo. 189,813. (No model.) A

To @ZZ whom it may concern.-

Be it known that I, AMANDA DE VoE,a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvementsin Invalid-Chairs; and I do hereby declare the following to beafull,clear, and exact description ofthe invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

This invention relates to invalid-chairs.

The object of the invention is to produce a chair which shall be simple in construction, easily operated, and capable of being converted by few adjustments to serve as a chair, cominode, lounge, or bed,and presentin the truest sense an invalids rest or friend and nurses assistant.

` With these objects in view, myl invention consists in a chair made up of a seat portion, a back pivotally attached thereto and capable of being adjusted to any desired angle relative to ir, and an adjustable frame connected to the seat portion and capable of being arranged to support the back at any desired angle.

Furthermore, the invention consists in a chair made up of a seat portion and back pivoted thereto, an adjustable frame connected to the seat portion and capable of being arranged to hold the chair at any desired angle, and a foot and leg rest provided with folding legs and capable of being adjusted to anydesired angle relative to the seat of the chair, or to form a continuation thereof to make abcd or lounge. Furthermore, the invention consists in chair made up of aseat portion provided with legs capable of vertical adjustment to raise or lower any desired part ot' the seat, and provided with vertical adjustable arms capable of being moved out of the way when a patient is to be placed upon or taken from the chair, a back pivot-ally attached to the seat portion and capable of being adjusted to and held at any desired angle in relation to the seat portion, an adjustable frame attached to the seat portion capable of being arranged to support the back at any desired angle, and a foot and leg rest provided with folding legs and capable of adjustment to any desired-angle relative to the seat portion,'or to form a continuation of the seat portion when the chair is to be used as a bed or lounge; and,finally,the invention consists in various novel details of construction,

whereby the various adjustments of the parts are facilitated and stability and strength are given the structure.

In the accompanying drawings, in which likeletters ot' reference indicate corresponding parts, Figure 1 is a side elevation, the parts being in the position assumed by them when the chair is not in use, showing a movable arm-cushion and one of the movable arms, the headed bolts attached toa fixed portion of the chair passing through slots in the arm which have an upper vertical portion and a lower horizontal portion enabling the adjustment; also showing the side of the commode-box, which box is slid under .the seat from behind, and one of the stops against movement of the box too far forward; also showing a downwardprojecting side of the bottom plate of theseatframe;also showing the adjustable legs;also showing the back of the chair and one of the racks, which are at the lower ends of the sides thereof,engaged by one of its notches with one of the ends of the spring-bar to hold the back in a desired position for rest while sitting; also showing one of the racks which are at the rear of the sides of the back to engage the upper cross-bar of the upward-extensible portion of the adjustable supporting-frame to hold the back in a desired position for rest while reclining,and one ofthe hinged side pieces or wings, which are slotted to engage and hold the ends of lthe upper cross-bar in notches of this rack and serve as side rests for the head of a patient while sitting; also showing the upward-extensible portion of the adjustable supporting-frame unextended, the inner swinging frame (not shown) not being swung up to support the upper cross-bar; also showing the trundle portion of the adjustable supporting-frame with legs to support its outer end, this portion being pushed under the chair and so pulling the upward-extend- Y ing portion against the rear of the chair; also showing one of the rods that project upward from the side bars of the trundle portion of theadj ustable su pportin g-frame laterally along the downward-projecting sides of the bottom plate, and then bend inward at a right angle over the sides upon the bottom plate, forming catches or hooks to hold up the inner end of the trundle portion of the adjustable supporting-frame; also showing, close to ac'atch, one end of a rod that extends through the side bars of the trundle portion of the supporting- IOO frame, as well as through the downward-projecting sides of the bottom plate, and supports a swinging hasp (not shown) that catches over staples at the front (shown) and rear (not shown) underneath the bottom plate to fasten the supporting-frame in a closed or in an extended position; also showing the adjustable and removable foot and leg rest, hung by a rod between the sides of its upper portion on projections from the front of the seat portion of the chair, an upward-curved tongue which projects outward from the central part of the rod passing through a slit in the front plate of the seat portion of the chair. and the hinge so formed being covered by a guard; also showing one ofthe spring-rods with springstop at the middle joint of the leg-rest; also showing one ofthe spring-rods which extend from the middle section of the leg-rest to its outer end and are provided with loops that catch over the foot-board when this is up and likewise serve to support a hook-rod which holds the foot-board in position when this is up; also showing the foot-board down and how it may serve as a support for the removable cover when the foot and leg rest is detached and the cover is rolled up or folded.

Fig. 5 is a side elevation of the foot portion of one of the chair-legs, showing in detail the means of adjusting the length of the legs, the lower end of the leg proper with a stop, the slotted sleeve upon this lower end with the stop in its slot, and the obliquelynotched pivoted plate. Fig. 6 is a vertical cross-section through the seat portion of the chair, showing the commode with the cover having flexible material around it, so that it may easily be slid under or out from the bars which keep it in place and be taken out and put in from the under side, also the side bars of the trundle portion ofthe extensible frame slitted longitudinally from above downward, taking upon the downwardprojecting sides ol' the bottom plate of the seat portion, and the hooks from the side bars catching over the bottom plate. Fig. 7 is a front view of the footrest, showing in full lines the legs extended and in dotted lines thc legs folded` also showing a hookrod, the loop-ended spring-rods, and pins on the front of the footboard for an elastic cord to hold the removable cover.

This chair may be divided into four principal parts-into a seat portion, aback portion, asupporting-frame portion, and a foot and leg rest portion.

In the drawings, A designates the seat pon tion, consisting of a suitable frame and having arms a, composed of plates of metal or pieces of wood provided with slots which have an upper Vertical portion and a lower horizontal portion,thron gh which slots pass headed bolts orl pins a', attached to a cross-piece of the frame of the chair, whereby the arms are made movable. Loosely attached to the side of the seat portion, as by cords, are cushions a2, and these cushions will rest upon the upper margins of the movable arms when these TIO are pushed up, and will lie loosely at the side of the seat when the arms are down.

Anarm is fixed in its extended position by pushing it upward until the headed bolts are at the bottom of the vertical slots, and then pushing it. horizontally until the bolts enter the horizontal slots, the corresponding cushion being raised upward to rest-upon its mar- 0in. b An arm is lowered by pushing-it horizontally until the headedbolts become disengaged from the horizontal slots andenter the vertical slots, and then pushing it downward until its upper margin is below or dush with the surface of the chair'seat, or allowing'it to fall by gravity, the corresponding cushion being bent or laid over until it is iiush with or below the surface of the chair-seat. It is obvious thatinstead of having cushions loosely at `tached to the seat they may be attached to the movable arms.

The purpose of having the arms and cushions movable is that when a patient is to be moved from a bed to the chair or from the chair to a bed an arm and cushion may be got out of the way and present no obstruction, while when seated in the chair one arm and cushion or both arms and cushions may be elevated to present a rest for the patient, and the construction by which this purpose is to be attained is strongly to be distinguished fromiany one in which the arms of a chair are fixed at different heights bymeans ot' a clamping device, since, in the rst place, by the construction shown in this application the arms are more ready of adjustment than by a clamping device, and, secondly, by having two or more horizontal and vertical slots and pinsin the nature of bayonet-fastenings the arm will always be held in proper horizontal position.

The seat portion of the chair is supported by legs a3, which have foot portions of peculiar construction. These foot Vportions consist of the lower end of the leg having a pin or projection, and a sleeve, at, upon the lower end of the leg and having a slot entered by the pin or projection and provided with a notched plate, a5, pivoted at its upper end, the notches being oblique and opening upward. The chair-roller is on the lower end of the sleeve. The purpose of this construction of the foot portion is to enable the chair readily to be raised and lowered.

The chair is raised by simply placing the hand under the seat and lifting it, when the lower portion of the leg will be raised in the sleeve, and the pin or projection will slip over the teeth of the pivoted plate until ,the desired height is attained, when, upon ceasing to lift, the pin will fall intoan appropriate notch of the plate, which plate takes the necessary position by gravity, and the pin will be held in place by the weight of the chair.

The seat of the chair should be suitably npholstered and have springs, and is provided with arsuitable opening for a commode-seat. This opening is closed by a removable cover, a, consistingof a plug of requisite size to iit the opening, and having flexible material projecting from it laterally. This cover is inserted from below, and is held in place by rods underneath the seat, the flexible material being slipped in over the rods. The purpose of this construction of cover is to be able to insert it and remove it from below, thus avoiding distnrbing the patient, and the construction is to be distinguished from that of other covers which have been inserted from below for the same purpose in that the cover of this application is held by the iiexible material and the rods, the exible material being slipped in over the rods, and is not held by the plug nor hinged.

At a suitable distance below the seat of the chair is a bottom plate, ai, which serves to support a removable commode-box, fr, provided with a door, i, at the rear, and having a handle, z, and has depending from its sides flanges a, which are provided with suitable slots, for a purpose hereinafter to be explained. Also depending from this bottom plate, near the front and back thereof, and preferably near the median line from front to rear, are two staples, a and al, the purpose of which will be explained farther on.

B represents the back of the chair, which is pivoted at a convenient point to the rear side of the seat portion, and in such manner as to be capable of movement to any desired angle relative thereto. This back has thelisual side pieces, and these side pieces have at their lowerl extremities racks b, which are engaged by the ends of a spring-bar, b, which is mounted and capable of sliding vertically in the frame of the chair, and engages any suitable notch of the rack to hold the back at the angle desired by a person sitting in the`chair. The springbar is provided with a handle, b2, both the spring-bar and the handle being at the rear of the chair, and by this handle the bar is drawn down to disengage the rack and allow the back to be adjusted outward. This handle of the spring-bar may also serve, by being caught over the handle a of the com mode-box, to keep thebox in place from movement outward, while stops w', striking against the legs of the chair, will prevent the box from being moved too far inward.

The rear faces of the notches of the rack I) slant or are curved forward, and the front faces thereof are straight, so that the back can be moved to a forward position relative to the seat by simply pushing it with the hand,while it is retained against backward movement, except upon disengagement of the spring-bar.

Besides serving asv a rest for a person while sitting the back may serve as a rest for a person while reclining, and. in this case it is released from engagement with the spring-bar and turned back; but when it is so released it IIO is necessary that it should be supported by other means than those previously described and be supported at different angles of inclination. To this end, therefore, the side pieces, in addition to being provided with racks at their lower extremities, have racks b upon their rear edges, and these racks are constructed to engage with a top bar of asuitable frame extended under the back, and in order that when such top bar has become engaged with notches in these racks it may be held there. The sides ct' the back are provided with hinged wings b", the hinges being at their front edges, thus enabling them to be swung forward, and having longitudinal slots which correspond to, or nearly to, the situation of the teeth when the wings are closed, so that when the wings are closed the slots in them will be over the ends of the top bar holding it in place. The hinged wings also serve as protection and as side rests for the head when a person is sitting in the chair, and perhaps not able to hold the head up.

C designates au extensible frame,which consists of a trundle portion, C', and an upwardextending portion, C2. The trundle portion consists of side bars, c, held together by a cross-bar, c'. The side bars are grooved above to receive the lower edge of the depending flange a.s of the bottom plate, and are provided with small rods, ci, which extend upward from their sides and are bent at a right angle to take over the upper surface of the bottom plate, forming hooks or catches to support the inner ends of the bars, the outer ends being supported by feet ci.

Extending from one bar to the other, near the hooks and through the downward proj ections of the bottom plate, is a rod, 0*, carrying a swinging hasp, c, having lateral projections c and ci, which catch over one end or the other of the bottom plate when the trundle portion of the extensible frame is pushed in or pulled out, and a perforation, c", which is pushed upon the staple a or the staple al, according as the frame has been pushed in or pulled out, and it is desired to fasten it in the one situation orthe other. As the rod c4 passes through the downward projection as of the bottom plate, in order to be able to move the trundle portion out or in the downward projection is slotted, as before described.

The upward-extending portion of the frame C2 consists of three distinct frames-a lower frame, a longitudinally-extensible frame, and an inner frame. The lower fratrie consists of the bars c, pivoted upon the rod c, which then constitutes t-he lower bar of the upwardextending portion of the entire supportingframe, and a tie-rod, c, between them, which then constitutes the middle bar of the upwardextending portion of the entire supportingframe. The middle frame consists of slotted arms, loops, or links om, curved upward and inclosing the outer ends of the bars c and ci, upon which they are free to move longitudinally, and a rod, c, iixed at the upper end o1i the links, which. rod then constitutes the top bar of the upwardextending portion. This top bar extends laterallyr beyond the frame, and has its ends suitably formed to engage with the racks b of the back ofthe chair. The inner frame consists of bars c, pivoted upon the middle bar of the upward-extending portion and joined at their upper ends by a pillow-bar, c, which, when the links are pulled out, is swung underneath the top bar, and so holds them extended. As the lower frame is pivoted on thc bar c', and the other frames are about and upon this lower frame, it follows that the entire upward-extending portion c2 is free to swing with the lower-most frame.

vl/hen the back of the chair is released from engagement with the bottom racks b and is tilted backward, and the middle frame is pulled out and the inner frame swung up, so that its upper cross-bar is under the top bar, forming a pillow or rest therefor, and the ends of the top bar are engaged with the racks b3, the back may thereby be supported at any angle with the seat, from its last engagement with the bottom racks, b, to a perfectly horizontal position of the back.

As before said, the ends of the upper bar, c, may be in any notch of the racks b", and may be retained there by turning the slotted wings down over the ends of the bar.

It' it is not desired that the back should be at a greater inclination than can be afforded by the racks b and spring-bar b', the support- `:ing-frame may be moved out of the way by swinging down theinner frame, which will allow the middle frame to sink by gravity, and then pushing in the trundle portion, which will bring the upward-extending portion close behind the seat of the chair. The outer end of the trundle portion will then be supported by a projection, c, on the lower bar, c', taking into the staple am.

When not needed, the commode-box may be removed, whereby it is more easily cleansed, and whereby, also, the general appearance of the chair may be improved.

D designates the foot and leg rest portion of the chair, and consists of three distinct portions-an inner portion, a middle portion, and an outer portion. The inner portion consists of side pieces, d, joined above by a rod, d', having at its middle part and extending outward a curved tongue, d2. rlhis portion is hinged to the seat portion of the chair by its rod d', hanging upon suitably-shaped projections at the front and sides of the chair, the tongue dA passing through an opening in a front plate of the chair-seat to forni an additional hinge and holding device. This tonguehinge is protected bya guard, d.

The middle portion of the foot and leg rest consists of the side bars, d, which are hinged at their upper ends to the side bars, d, and are fixed at any desirable angle thereto by springrods d5 upon the bars d taking into notches upon the upper ends of the middle portion, forming a spring-stop. To release the middle IOO IIO

section from the inner one and allow it to be turned up or-down, the spring-rods are compressed against the sides d, when their ends,

which may be of any suitable shape, will be pushed inward beyond engagement with the notches on the inner ends of the middle portion. The outer ends of the side bars, d, are connected by a rod, d6.

The outer portion of the foot and legl rest consists of a foot-board, dl, having depending from and pivoted to it legs de. rIhe foot-board 1s pivoted upon the rod d, and is held in place partly by Springrods d,having loops on their ends which catch over the edges of the footboard,l and partly by a hook-rod, d10, which is linked at one end in one loop and hooks at the other end into the other across the outer face ofthe foot-board. A removable cover `may be spread overY the foot and leg rest, and be fastened at the upper end thereof upon hooks d upon the legs of the chair, and extend over the arms where it is buttoned or otherwise fastened, and so, if desired, over the back.

The entire chair has a permanent cover of canvas or other suitably strong material, double if required, and the removable cover may be of any suitable material. The removable cover may be removed and replaced in a very short time, and it turns over the footboard and can be folded there when desired. To this end the foot-board is capable of being turned down, as shown in Fig. 1, forming, when detached, a support for the removable cover.

To turn the foot-board down, the rod is unhooked and the spring-rods are pulled outward, when pressure outward upon the board will bring it down to the desired position. Before the board is'thus turned down the pivoted legs may be folded. After the board has been turned down the hook of the rod may again be placed in its loop of the springrod. Upon the front of the foot-board there are also pins, buttons, or the like to attach the removable cover by an elastic cord or by elastic cords, and the cover may then be passed up over the foot and leg rest. and extend over the arms, where it is buttoned or otherwisesecured, and thence pass up on the back and there likewise be secured.

For transportation, the back should be folded over the seat and the foot and leg rest portion be held iiat upon it.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the seat portion of a chair having headed bolts projecting laterally therefrom, of a piece or slab of metal or wood provided with slots having a longitudinal and a horizontal portion which take upon the headed bolts and constitute movable arms, substantially as described.
