To all whom it may concern:

Be it known that 1, JAMES VVALLAOE, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Theater and like Chairs, of which the following-is a specification.

This invention relates to folding chairs, and more particularly to that class of chairs which is used in theaters and other public assembly rooms.

It is one of the objects of the present invention to provide a simple, substantial, cheaply manufactured chair of the character described, which is especially adapted for installation and use in places where the seats are liable to vbe crowded and where the audience is ever and continuously changing; 2'. e., a seat which can be quickly and easily raised by the occupant to make aisle space when a person desires to pass.

Another object of the invention is to provide a seat which is so constructed that any number of same may be arranged inthe form of a semicircle, or the like, without cramping the pivotal connections of the seat or interfering with the free working of 7 showing the seat in lowered position. Fig.

2 is a similar view showing the seat in the raised posltlon. Fig. 3 1s a plan view, partly in section, showing a number of seats connected 111 the form of a semicircle. Fig. 4'

is a detail perspective view of plate 4. Fig. 5 is a cross section of the seat frame showing the plate 4 in plan view.

Referring to the drawings, A indicates the standards or side frames of the seat, between which the back sections are secured, as at 2. The side frames are substantially T-shape in cross sectionfand the front edge of each frame is provided with laterally extending lugs 3, one, pair of lugs being formed on each side of the frame. Pivotally mounted in each pair of lugs is a plate 4: and mounted at one side of each plate is a pivot member 5, a stop 6, and a set-screw 7.

The seat proper, indicated at 8, is secured I to a pair of bracket plates 9 in turn are carried by the plates land pivots; 5

Each bracket plate is extended toiz-forma pair of stops 10 and 11, one to limit the'upward movement of the seat and the otherto support the seat in the loweredv position.

Pro ectingfrom one side ofea'ch" bracket plate is a pivot pin 10, and connecting. said pin with the arm of the chair, indicated at l3, is a link 14: which projects through and is guided in a slot 14: formed in the frame A. Thearms are in this'instancepivotally connected, as at 15, to the back ofitheseat frame. The link connection between the arms and the seat provides a means" by which the seat may be raisedor lowered I through means of the arms 13. The pivotal mounting of the arms, together with link connections between same and the seat, is of great importance as it greatlywincreases the utility of the chair, especially in theaters and like places where the seats are liable;

to be crowded and where 'the audience is ever and continuously'changing. The occupant of 'a' chair has a natural tendency to place the'hands on the eX- tremities of the arms of the chair and they are thus in a naturalpositionv to grasp and raise same, when standing up to make aisle space for passing persons. The occupant is thus entirely. relieved of stooping down and grasping the front: edge of the seat.

Another important feature of the present invention is the provision ofthe pivotally mounted plates 4: in which the seat proper is supported. These permit the seats to be' arranged in a semi circle, or the like, without crowding the pivotal connections or interfering with the free working of the seats. When arranging the seats in a semicircle, as

indicated in Fig.3, itis only necessary to adjust the set-screws 7 in such a manner that they will-hold the plates 4: at a slight angle, as indicated at 16, with relation. to the seat frame. A number of chairsmay thus be arranged in practically any shape without interfering with the. free workingv of the seat.

The bracket plates9 are proper and the bracket plate. This, together with the pivotal mounting. of the slotted, as'at 17 to permit adjustment between the seat" plates 4:, permits the seats to be removed at i i any time without interfering with the main frames A or the back portions of the seats.

Secured to the front frame, by a screw 18, or similar means, on each side of the frame between the lugs 3, is a pair of angle plates 19. These are provided for the purpose'of preventing the seat, with connected plates 4:, from being lifted out of engagement with the lugs 3.

The materials and finish of the several parts of the chair are such as the experience and judgment of the manufacturer may dictate.

Various changes in form, proportions and minor details of construction may be resorted to Within the scope of the appended claims and I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by' Letters Patent is 1. In combination with a chair frame having a back, and a seat pivoted to the frame, arms pivoted to the frame, and links pivoted to the arms and pivoted to the seat at points at a distance below the pivotal points of the seat but closely adjacent the seat pivotal points whereby the seat may be raised up by but slight up movement of the arms and which movement of the arms causes-same to extend at but slightly less than a right angle to the back.

2. In combination, a chair frame, a plate pivotally connected thereto for movement about a vertical axis, a seat, a bracket secured to the seat and formed with an opening, a fixed pin projecting laterally from the pivotal plate and freely engaging in the opening of the bracket whereby relative separable movement between the latter and plate will dislodge the bracket from the pin, and adjustable means for holding the plate positively in an adjusted position against movement tending to separate the latter from the bracket.

3. In combination, a chair including spaced frames, a plate pivoted to each frame for movement about a vertical axis and ar ranged to oppose the plate of the other frame, a pin projecting from each plate toward the other plate, a seat including means freely receiving the opposing pins whereby on separable movement between the pins the seat will be dislodged, and screw means carried by the plates and adapted to engage with the frames for holding the plates against swinging movement from the seat.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
