CHAIR.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed December 30, 1919. Serial No. 348,257.

To all whom it may concern Be it known that I, GAYLE L. SQUIRE, a citizen of the United States, residing at Hastings, in the county of St. John and State of Florida, have invented a new and useful Chair, of which the following is a specification.

This invention relates to new and useful improvements in chairs and more particularly to chairs especially constructed for use in public halls, theaters or the like, wherein it is necessary to employ chairs wherein the seat portions thereof may be moved to a position in substantially parallel relation with the back thereof.

The primary object of the invention is to provide a chair of this character wherein the back will have pivotal connection with the seat portion thereof, whereby movement of the back will produce a relative movement of the seat portion to move the seat portion out of the path of travel of persons entering between lines of chairs.

A further object of the invention is to provide a means carried by the lower extremity of the back-rest of each of the chairs for contacting with the seat portion thereof for setting up a wedging action between the seat and back, when the seat is moved to its open position, to cause a substantially rigid connection between the seat and backrest to prevent movement of the seat portion with relation to the back-rest.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a side elevational view of a seat constructed in accordance with the present invention, one of the supporting legs thereof being removed,

Fig. 2 illustrates a rear elevational view of a portion of a seat.

Fig. 3 illustrates a fragmental detail view of a seat disclosing a connection between the backrest and the supporting legs thereof, and

Fig. 4 illustrates a fragmental sectional view in elevation, of this connection.

eferring to the drawing in detail, the reference character 5 designates the base or supporting legs of the seat which are provided with angularly disposed flanges 6, formed at the lower inner edges thereof, which flanges are apertured as at 7 to receive suitable securing means, not shown.

The supporting logs are provided with right angled supporting flanges 7' formed on the inner surfaces thereof, which pro vide stops or rests for the seat portion 8 of the chair, to support the seat portion in a horizontal position, when the same is in use.

As shown, an upwardly extending arm 9 forms a part of each of the supporting legs 5, and provides a support for the pivot pin 10, which passes through a suitable opening formed in the back-rest 11, the opening being disposed at a point in spaced relation with the lower end 12 of the back-rest, so that the upper portion of the back-rest acts as a lever to cause the operation of the seat portion 8, in a manner to be hereinafter more fully described.

A segmental gear 13 is formed at the base of each of the side arms of the back-rest, the teeth thereof cooperating with the teeth 14 of the gear wheel 15 formed integral with each side member of the seat portion 8. which seat portion 8 is pivotally connected to the supporting legs 5 by means of the pins 16.

Disposed at the rear of the segmental gear 13, is a stop 17 formed integral with each of the side arms of the back-rest, the

same being shown as having a forward curved portion contacting with a similar curved portion of the gear wheel 15.

It will be seen that when the seat is in a position as indicated by Fig. l of the drawing, the stop 17 engages the gear 15 for restricting movement of the back with relation to the seat 8, and at the same time prevents movement of the seat portion 8 with relation to the back-rest.

In operation, the upper portion of the back-rest is grasped by the person to occupy the seat, the backrest is then mo ed to the rear with the result that the teeth of the segmental gear revolve the gear wheel forming a part of the seat portion 8 to cause the seat portion 8 to move to a position in horizontal relation with the back-rest.

In order to move the seat to its inoperative position, it is necessary to move the back-rest 1n the opposite direction, which movement causes the seat portion to move upwardly, to a position in parallel relation with the back-rest. V

Having thus described the invention, what is claimed is: r

In a chair,- supporting legs, each of said supporting legs having an upwardly extending arm, a back rest comprising spaced arms pivotally supported by the upwardly extending arm, each of said spaced arms having a segmental gear formed at the stop formed integral with each of the spaced 7 arms, and adapted to engage a portion of the segmental gearsof the seat portion for restricting movement of the back rest.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the-presence of two Witnesses.
