JOHN F. SELL, OF BUFFALO, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 562,428, dated June 23, 1896.

Application filed December 23, 1895. Serial No. 572,977. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. SELL, a citizen of the United States, residing at Buffalo, in the county of Erie and 'State of New York, have invented certain new and useful 1m provements in a Combined Operating Chair and Table for Physicians and Surgeons, of which the following is a specification.

My invention relates to certain improvements in a combined table and chair for physicians and surgeons, and it will be fully and clearly hereinafter shown and described, reference being had to the accompanying drawings, in which- Figure 1 represents a perspective View of the table, showing the cover closed, with the foot-rest raised to the limit of its upward position. Fig. 2 is also a perspective view of the table, showing the cover raised upward and the foot-rest lowered. Fig. 3 represents a vertical longitudinal section on or about line a a, Fig. 5, showing the cover closed and the position of the several parts connected with it. Fig. 4 is also a vertical longitudinal section on or about line a a, Fig. 5, showing the position of the several parts when the cover is raised upward. Fig. 5 represents an inverted plan view of the table, showing a horizontal section through the table on or about line b b, Fig. 3, the several parts in view being in the same position as in said Fig. 3. Fig. 6 represents a plan piew of a portion of the table, one of the side arm portions and foot-holder being removed, so as to expose the mechanism below it. Fig. 7 is a vertical section on or about line 0 c, Fig. 6. Fig. Sis ahorizontal section on or about line at d, Fig. 3, showing an inverted View of the foot-rest and the means for connecting or disconnecting the foot-step. Fig. 9 represents a horizontal section on or about line 6 c, Fig. 1, showing the means for adjusting the leg-rest. Fig. 10 represents an inverted plan View of one of the side arm-strips and foot-holder, showing its construction. Fig. 11 represents a horizontal section on or about line 9 g, Fig. 4, showing an inverted view of the mechanism for holding the inclining portion of the top of the table in position when adjusted. Fig. 12 is a vertical section on or about line f f, Fig.

11, showing the mechanism for locking the segment-gear.

My improved device combines the advantages of an operating-chair and an operatingtable, as will appear farther on.

Referring to the construction in detail, 1 represents the legs of the table, or of the chair when used as a chair.

2 and 2 are the. side frame-pieces, and 3 the end frame-piece, all secured together in the usual way.

The numerals 4 and 4 represent two side portions which extend the whole length of the table, one on each side. (See Figs. 1, v 2, and 5.) They are firmly attached to the table and form permanent side pieces thereof when the hinged movable top 5 is shut down, as in Figs. 1 and 3, and the arms of a chair when the top 5 is turned up, as in Fig. 2, in which case it forms the back of the chair.

Rigidly secured to the side and end framepieces of the table is a stationary top 6, which extends forward from the rear end of the table and is provided with hinges 7, (see Figs. 3, 4, and 5,) to which the cover 5 is secured so as to be capable of turning thereon. The table is also provided with a bottom portion 8, permanently secured to the rear end piece 3 and the two side pieces 2 and 2. Through this bottom portion is a narrow opening 9, near the center, and a narrow slot 10. (See Figs. 3 and 4.) At the front end of the bottom portion 8 is a depending portion 11, supported by one or more brackets 12, and a strengthening portion 13, through which the slot 10 passes.

On the top of the front end portion of the bottom 8 is mounted a seat portion 14. This seat portion 14 is secured'by a screw 15, which passes through the slot 10, thereby permitting the seat portion 14 to be moved out or longitudinally back and forth as far as the slot 10 will allow.

To the under side of the hinged top portion 5 is rigidly secured at the points 15 and 15 by screws 16, or in any well-known way, a semicircular bar 17, (see Figs. 3, 4, and 5,) having on its inner curved side a series of gearteeth 18. This curved bar 17 passes through an opening 19 in the stationary table-top 6 (shown in Figs. 3 and 4) and moves through said opening 19. as the top 5 is turned up or down on its hinges 7, the hinges 7 being exactly in the center of a circle of which the curved bar 17 forms a part.

20 represents a longitudinally-sliding bar, having a slot or opening 20, through which the curved bar 17 passes. The bar 20 is secured to the under side of the table-top 6 by a cross-bar 21, having a depression in which the bar 20 fits and slides easily between it and the under side of the table-top, to which it is secured by screws 22. (See Fig. 5.) To the rear end of the sliding bar 20 is pivoted a lever 28, which is pivoted to the under side of the table-top 6, at or about the point 24, and is provided at its free end with a handle 25, that extends out through the side of the table. (See Fig. 5.)

From the above-described construction it will be seen that the inclination of the hinged table-top 5 may be adjusted to any suitable point, and then by moving the handle in the direction of the arrow V the movable bar 20 will move in the direction of the arrow V, Fig. 5, and thereby move the portion 26 (shown in said Fig. 5; see also Figs. 11 and 12) in between two of the teeth 18, that the inclination of the table or chair-back 5 may bring into position and thereby rigidly secure it at that point.

To the front end of the pivoted table-top 5 is hinged, by hinges 27, (see Figs. 3 and 4,) a movable seatportion 28, having an angular arm 29, rigidly secured to the lower side by screws 30. (See Fig. 4.) To the opposite end of this arm 29 is a hinge-piece 31. An arm 32 is pivoted to the hinge-piece 31, and its other end is pivoted, by a pin 33, to the under side of the stationary table 0. (See Figs. 3 and 4.) There may be two arms 20 and 32, as shown in Fig. 5, if desired.

It is obvious that if the hinged table-top 5 be made to swing in either direct-ion on its hinges the pivoted arms, connected as above described, will keep the seat portion 28 in a substantially horizontal position. (See the two positions of the top 5 in Figs. 3 and 4, one being indicated by dotted lines in Fig. 4.) The seat portion 28, as shown, is provided with a semicircular portion 28, adapted to it the portion 14", on the seat portion 14, when the table-top 5 is inclined upward substantially as shown in Figs. 2 and 4.

34 represents a removable foot-step. It is mounted 011 two brackets 35, each secured to a verticallymovable bar 36, one in each front leg of the table, one of which is shown in Fig. 8.

The brackets 35 extend forward from the vertical bars 36, and, as shown in Fig. 8, widen out into something like a spoon shape; but the shape is immaterial as any suitable form can be used. Neareach end of the under side of the foot-step is rigidly secured, by screws 37,a correspondin gly-shaped outward-extending portion 38, leaving a depression within which the brackets 35 fit nicely and are secured by means of a pivoted latch 39, which shuts under the latch-catch 40. (See Fig. 8, where this is shown.)

To the upper end of each of the vertical bars 36' is secured a fine-wire cable 36, or rope or its well-known equivalent, a flexible cord of any well-known kind. These cables or ropes pass up and over a grooved frictionroller 41, (see Fig. 7,) at each side of the table. From thence they pass horizontally through an opening in the top of the inner side por tions 42 at one side of the table and 42 at the opposite side, and below the side pieces 4 and 4. (See Figs. 6 and 7.) From thence they pass down over a friction-roller 43. (See Fig. 6, also Figs. 3 and 4.) They then pass down under and around friction-rollers 44, and from thence they pass up to and are secured to links 45, which are rigidly secured to the hinged seat portion 28.

From the above description it is evident that if the top 5 be turned upward, as in Figs. 2 and 4, as it is moving upward (turning on its hinges 7) the seat portion 28 is descending, and in doing so slackens the cords 36, so that foot-step 34 (being heavy enough) moves downward by gravity, and an opposite movement of the tabletop 5 will cause the said foot-step to rise upward as the top 5 is being moved toward a horizontal position. This is an important feature, as will appear farther on.

At the front of the table are two verticallyadjustable leg-rests 46 46. (See Figs. 1, 2, and 3.) They are mounted on vertical rods 47, which pass down through each front leg and are secured at any point of their vertical adjustment by means of thumb-scrcws 49. (See Figs. 1, 2, 6, and 9.)

Secured to and under each of the two side portions 4 and 4 is a heel-rest 49. These heel-rests are adapted to slide out or back in slideways 50, (see Fig. 10, which is an inverted view,) the sliding portion of the rest 49 being kept in the slideways 50 by the cross bars or plates 51.

When it is desired to use the device as a chair, it is adjusted in the position substan tially as shown in Fig. 2, the back being inclined more or less as may be required.

\Vhen it is necessary that an operation should be performed on a table instead. of a chair, the patient is not required to climb up onto the top of the table, neither is he required to be lifted up thereon, (an operation which under some conditions would be very painful.) All the patient has to do is to sit down when the chair is in substantially the position shown in Fig. 2. The top 5 is then carefully turned downward, and as the pa tient is being brought to a horizontal position the seat 28 rises upward until the table comes into a horizontal plane with it. At the same time the table 5 is moving the patient to a horizontal position the foot-step 34: is rising upward, thereby supporting the feet and limbs and lifting them up in an easy natural manner. The patient is therefore easily placed in a horizontal position on the table with as little inconvenience and trouble as possible.

The usual upholstered cushions are used on this chair or table as may be required, but as cushions are well known for such purposes they are not described here.

I claim as my invention- 1. In a surgeons operating table or chair, the combination of an inclinable table-top with the stationary top of the table to which the inclinable table-top is hinged, a seat portion hinged to the front end of the inclinable table-top, an arm pivoted to the under side of the stationary table-top having its opposite end pivoted to an arm rigidly secured to and extending back from the hinged seat portion, whereby the hinged seat portion is kept in substantially a horizontal position while the hinged table-top is at any desired inclination, substantially as described.

2. In an operating table or chair, the combination with an inclinable table-top of a hinged seat portion at the front end thereof, a foot-rest, vertically-movable bars to which the foot-rest is secured, and flexible cords connecting the same with the hinged seat portion, whereby a movement upward of the rear end of the inclinable table will allow the foot-rest to move downward, or vice versa, substantially as described.

3. In an operating table or chair, the combination with the inclinable table, of a toothed semicircular bar rigidly secured to the under side thereof, a longitudinally-movable slotted bar through which the toothed curved bar passes as the table is inclined on its hinges, said slotted bar being. mounted in a slideway secured to the under side of the fixed tabletop, an arm pivoted to the under side of the fixed table-top having its handle end extend out through the side of the table and its opposite end pivoted to the movable slotted bar for bringing the engaging portion of said bar or out of engagement with the teeth in the curved bar or into engagement therewith and thereby disengaging or securing the inclinable table at any point desired, substantially as described. I

4:. In an operating-table, a stationary tabletop, an inclinable table-top hinged thereto, a seat portion hinged to the front end of the inclinable table-top, means substantially as above described for keeping the seat portion in a substantially horizontal position while the inclinable top is at any required inclination, a vertically-movable horizontal footstep, and means connecting with the inclinable table-top by which both the hinged seat portion and the vertically-movable foot-step are operated thereby, substantially as described.

5. In an operating-table, the combination with the table-supporting frame of a hinged table-top, a seat portion hinged to its descending end, and means substantially as above described for keeping the seat portion in a horizontal position or nearly so while the table-top is being turned upward to form a chair-back and the seat portion is being lowered to its proper position.

6. In an operating table and chair combined, a removable foot-rest provided with socketed portions on its under side, adapted to fit over brackets extending forward from the front of the chair, in combination with a latch mechanism pivoted to the under side of the foot-rest for securing said foot-rest when in place thereon, substantially as described.
