REVERSIBLE SEAT FOR CHAIRS.

To all whom it may concern:

Be it known that I, honour LIBENSGI'JK, a. subject of Austria, residing at Elizabeth, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Reversible Seats for Chairs, of which ilnproven'ient the followin is a specification.

My invention relates in particular to the class of chairs known as barber chairs.

It is well known that the seat of barber chairs become heated from the temperature of the body of the occupants, owing to almost constant use, making, it more or less uncomfortable to each succeeding occupant.

Tlherefore, the object of my invention is to provide such a chair with a seat adapted to overcome the above stated condition of discomfort, by applying to such chair a reversible seatand foot-power actuated means for reversing the same after use by each individual.

With the above object in view, the invention consists in certain features of construd tion, in certain parts, and combination of parts, as hereinafter described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, said drawings representing thefollow ing views:

F igure 1 is a side elevation of a chair having niy improvement applied thereto. Fig. 2, is a plan thereof, in section on the l ne XX of Fig. 1. Fig. 3, is an enlarged side elevation of the seat, in section. Fig. 4, is a partial side elevation of the seat, with a portion sectioned, as it would appear after elevation and preparatory to its reverse seat ing on the chair. F ig. 5, is a transverse section of. one of the automatic adjustable weight containers of the seat. Fig. 6, IS a fragmentary sect-ion of the seat frame.

In the several views given, like detail parts of the structure, where appearing, are designated by like numerals and referred to by such in the following description.

The invention is adapted to be applied to any suitable form of chair, the one here shown being provided with a seat support in the form of a ledge 1 upon the mner opposite sides of the seat surrounding portion 1 of the chair frame, a support of some form being necessary.

The seat comprises av suitably constructed seatQ. cushioned upon opposite sides, se-

cured within a frame and adapted to normally engage upon the said supporting ledges .l of the chair, the two opposite sides of the frame 3 being each provided with a suitable catch 1- actuated by a spring 5. Within and at two opposite sides of the seat is arranged an automatic adjustable weight in the form of a metal ball 6, each disposed within a container casing 7 secured to the frame of the scat, said casings each including two connected parallel paths, one end of each path being curved where it enters the straight end. of the other, as shown, said casing being preferably lined with a sound deadening material 8.

To Ullt'll of the two opposite sides of the seat. frame portion 1' of the chair is attached a downwardly extended bracket formed of the two parts 9 and 9',respectively,' and to the. lower end of the bracket proper 9 of each is pivotally connected a lever 10, the rear ends of each of said levers being conneeted by a cross bar 11. To the forward end of each of the levers 10 is pivotally connected a vertically disposed link' 12, each of said links engaging at its slotted portion with a pin 13 projecting inwardly from the side of the seat. supporting frame of the chair, the extreme upper ends of said links being: connected to the seat by the pivots 14.

In practice, either the chair or the weight containers in the seat should be positioned sligthly out of a horizontal, so that the ball weights shall always be positioned at the forward end of the seat, as shown in Fig. 3, when said seat is at rest upon the chair.

To reverse the'seat, the operator places one foot upon and presses downwardly upon the cross bar 11, causing the seat to be elevated, during which elevation the weights 6 overbalanccs the same and causes its forward end to rapidly descend, forcing the said seat to swing past a vertical osition and as it swings past the vertical position the spring actuated catches 4 thereof are depressed by and during their passage of the then elevated links 12, which catches immediately after passingthc links spring outwardly and prevent the seat swinging forward, said seat being held in momentary suspense as shown in Fig. 4. By releasing the pressure of the foot upon the bar 11, the seat descends, the then lower seat frame 3 engaging with t e supporting ledges 1 of the chair and slides therealong.

until fully seated in the chair, the Weights "tion of rest in the chair.

6 rolling forivard to their normal position assoon the seat is returned to its posi- Having thus shown and described my invention, What I claimend desire to secure by Letters Patent, i's:

1. The combination of a chair frame, a reversible sea-t arranged thereon and pro. vided with: an automatically adjustable weight normally located at its forward end and foot-power actuated mechanism extend ing up to and pivotally connected at opposite sides of the seat for elevating the'same, said weight adapted to swing the seat past a vertical position when elevated to reverse the same. i v

2. The combination of a chair frame, a reversible seat arranged thereon and provided with an automatically adjustable Weight normally located at the forward end, a foot-power actuatedmechanism extending up to and pivotally connected at opposite sides of the seat for elevating the same, and spring catches on the frame of the adjust able seat, said Weight adapted to swing the seat past a vertical position when elevated to reverse the same, and said spring catches adapted to engage the actuating mechanism to prevent a return swing of the seat.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing Witnesses.
