SURGICAL CHAIR.
SPECIFICATION forming part of Letters Patent No. 289,743, dated December 4, 1883. Application filed May 7, 1883. (No model.)
.To all whom it ntay concern.-
Be it known that I, FRANKLIN E. YOUNG, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Surgical Chairs, of which the following is a specification,reference being bad therein to the accompanying drawings.
This invention relates to certain new and useful improvements in that class of chairs used for surgical purposes that will admit of easy adjustment to the various positions necessary for examinations or special operations upon the patient, all of which will be hereinafter more particularly described, and pointed out in the claims.
In the accompanying drawings; forming part of this specification, there are four sheets, in which Figure 1 is a perspective view of the chair in one position as in ordinary use for sitting. Fig. 2 represents the chair extended and in a horizontal position, the seat elevated to a level with the arms. Figs. 3 and 4 are details of the clamp for securing the stirrup in any position. Fig. 5 represents details of the device for clamping and holding the back at any angle. Figs. 6 and 7 are detail views of the devices for locking and unlocking the seat. Fig. 8 is a perspective view of the chair in another position, with the back horizontal, the seat lowered, and the leg-rest dropped from the position shown in Fig. 2. Fig. 9 is an un derneath View of the back and seat detached from the frame, showing the apparatus for coupling and uncoupling the back and seat. Fig. 10 is a transverse section of Fig. 9 on line .2 z.
Arepresents the frame of a chair, which can be made of any suitable material and substantial and weighty enough to stand firmly upon the floor. The feet may be so constructed as to admit of being secured to the floor. The arms A are permanently fastened to theupper ends of the standards or legs of the chair, and are covered with upholstery,to form comfortable cushions on top.
B is the back of the chair, which is properly framed and upholstered. It is attached to the hind legs, aa, by pivots 0, about six inches from the lower end, which fit into angular sockets c, forming part of the back legs or standards, on, asseen in Fig. 1, Sheet 1. The
back is also connected to the seat D at the lower end by straps or narrow plates of metal I) b, which serve as hinges. The strap 12 on one side seen in Fig. 1) is straight. Strap b (seen in Figs. 2, 7, and 8) is continued and curved, so that it not only acts as a strap by means of its connections with the back and seat, but is also a lever, 0, having a handle, 0, as will be hereinafter explained. The seat D is supported at the front upon the metallic straps d d on the sides of the leg-rest E by a pivot-joint, (Z. i The straps d d are also pivoted to the chair-frame A at their upper ends, inside of each arm-rest A, and they are provided with two slots, (1 and d. The lower slot, d., is made open to let the bolt of the leg-rest drop out when the operator desires the leg-rest to drop from the horizontal to a perpendicular position, as seen in the broken lines Fig. 2. The leg-rest E has attached to it a footboard, F, which ispivoted or hinged at 6, so that it may be turned, as shown in Fig.- 8. At the rear end of the seat D the straps b and b are also pivoted to it, as they are to the lower end of the back B. These straps b b are united by a cross-bar, G, as seen in Figs. 6 and 7, which bar Ghas on ita sliding hook, that engages with a catch-plate, H, secured to the bottom of seat D.
The sliding hook g is operated by the spiral spring g and the knob g on the end of crossbar G, and which is held on the bar by the pins h h in the slots h h when it is desired. The sliding hook g fastens the side straps or plates 1) 11, allowing motion only at the pivot 11 at the lower end of the back B until the hook is pushed in to free it from the catch H, when the seat D and the leg-rest E will resume their position, as seen in Fig. 8, while the back B will remain in a horizontal position or at any inclination which may be required. The headrest I is shown in detail in Fig. 2.
I is a socket-iron fastened to the rear of back B, having on it a ball, '5, and thumbscrew j, to adjust and support the head-rest I at any elevation.
z" t" are curved clamps, provided at their ends with cushioned pads i '11, and which can be secured by clamp-screws jj, provided with corrugated or serrated surfaces, as illustrated cases, in the back position it is necessary to i ments.
and these difficulties are entirely overcome by in Fig. 4.. These clamps are used to hold the 1 head firmly in: operations of a delicate nature upon the eyes or throat, serving thereby the purpose of an assistant and in a better manner.
The head-rest and its clamps, for securing it and holding the head, will form the subjectmatter of afuture application.
The stirrups K are made hook shape 011 the ends of iron rods, pivoted under the arms A to the front legs or standards in the heads of bolts 7c, passing through the clamp K, which has on the interior faces serrated or corrugated surfaces, as shown in Fig. 4, and which are secured together by clamp-screws K, and the stirrup-rod is fastened by a clamp-screw, K, Fig. 3. \Vhen the stirrups are not in use they are turned under the arm-rests, as seen in Fig. 1.
In Fig. 5 is shown the'device for clamping andholding thebar N, which sustains the back B at any angle with the seat D and the legrest E.
L is a block secured to the hind leg of the chair-frame A, in which block is a horizontal dovetail mortise, Z, and a vertical rectangular mortise, Z, having dentations or corrugations upon one side of the mortise. A dovetailed plug, M, having a stem, m, and knob m, is fitted to mortise Z, and a dentated rod, N, of rectangular cross-section is fitted to the mortise Z, having one side dentated or corrugated to correspond with the side of mortise Z. By pulling out the knob m the rod N can be secured to the block at any elevation required. By pushing in the knob m the rod N will be released, and it can be moved up or down, as may be desired.
In the treatment of rectal and uterine dishave the patient s hips atthe edge of the bed, table, or chair-seat, and as it is inconvenient and embarrassing to lift the patient into proper position, it becomes desirable to avoid that,
this device. 7
When a patient is placed in a horizontal position inthe chair, as it is represented in Fig. 2, the feet are to be pla lced in the stirrups K K. The-knob m is then to be shoved in with the left hand, and with the right hand. on the handle O', attached to the crank part 0 of the lever-strap I), let down the seatD and leg-rest E, as seen in Fig. 8. This leaves the patient in the proper position, with the hips resting on the lower end of the back B without being lifted forward. The seat D is then convenient to place on it a basin or instru- The foot-board Fis then turned back out of the way," as in Fig. 6,
and the operator sits down in front of his work, and in this way the chair is adapted to the patient, instead of adapting the patient to the chair, and it also gives the most favorable position, with the greatest facility and the least embarrassment and exposure.
To get the patient out of the last-described position, bring up the seat D and leg-rest E by means of the handle 0 and lever O of strap 1) until the released hook g catches the plate H, place the feet upon the leg-rest E. Then the patent can easily come to the sitting posture, and the back B will follow, and the chair be again as in Fig. 1.
To attain either the rightor left lateral positions, place the patient in the horizontal position, as heretofore described, and as illustrated in Fig. 2, turn the patient on the side,
with the hip on the arm of the chair. Then drop the leg-rest E out of the way. This is done by pushing it until the sustainingrbolts drop out of the slots: ,when by its ownweight it will assume the vertical position, as in broken lines in Fig. 2 and solid lines in the other figures.
WVhen the chair is to be folded for transportation, the back B is lifted out of the bearings c c and turned down, as shown in dotted lines in Fig. 8. The seat D is let down, and leg-rest E, with foot-board F, are all as represented in that figure, and the stirrups turned under the arm-rests. The chair is then prepared to be placed in a box or case, as may be desired;
Having described my invention, what I desire to claim as new, and secure by Letters Patent, is Y 1. The combination, with the supportingframe, of the back pivoted thereto, a seat pivoted at its front end to the frame, substanstantially as described, links pivoted to the seat and back, and means, substantially asset forth, for connecting the links rigidly with the back and disconnecting them, as and for the purposes set forth.
2. The combination of the supportingframe, the back B, pivoted to the frame, the seat D, pivoted at its front to the frame, substantially as described, having the lock-plate H, the side straps, b I), pivoted tothe back and seat, as set forth, the bar G, secured to the straps I) b, and locking-catch g, and the handle 0 0, attached to the side strap, 71, substantially as and for the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
FRANKLIN E. YOUNG.
