SPECIFICATION forming part of Letters Fatent No. 606,112, dated June 21, 1898.

Application filed October 12, 1897. $erial1l'o- 654,9187- (No model.)

To ctZZ whom it may concern:

Be it known that we, JAMEs GLENCAIRN AR- MOUR and CHARLES SoUTHoRN, subjects of the Queen of Great Britain, residing at Liverpool,'in the county of Lancaster, England, have invented certain new and useful Improvements in Chairs with Turn-Up Seats, of which the following is a specification.

This invention has reference to chairs with turn-up seats, such as are used in theaters and other places where space is limited.

In such chairs as ordinarily constructed great inconvenience and delay are experie'nced'when any of the chairs have to be removed or any'of the parts require to'be repaired or reupholstered; and our object is to' obviate these difficulties;

In carrying out our invention we provide a series of frames or standards, usually of castiron, each of which, except the two at theex treme ends ofthe row, serves for two seats, and we arrange the seats, arms, and backs so that any one can be instantly removed or replaced for repairs, (to, without disturbing any of the others.

In the accompanying drawings, Figure I shows in front elevation a row of chairs constructed according to our invention. In two cases the seats are turned up, and in the case of the chair-at'the extreme right end the seat, back, and one arm are removed. Figs. II and III are side elevations showing, respectively, the seat turned down and turned up. Fig. IV is a side elevation of one of the standards. Fig. V is a front elevation, and Fig. VI is a plan view, of the same. Fig. VII is a fragmentary section on line A A of Fig. IV, and Fig. VIII is a fragmentary section on line B B of Fig. IV. a Fig. IX is a detail side view of a modification of the lower part of the standards. Fig. X is a plan view of the same. Fig. XI is'a sectional view on line C Gof Fig. X. Fig. XII is a plan view of one of the seats. Fig. XIII is a side elevation of one of the seats. Fig. XIV is a front elevation thereof; Fig. XV is a plan view of oneof the backs. Fig. XVI is a side elevation, and Fig. XVII a front elevation, thereof. Fig. XVIII is an invertedplan view of one of the arms. Fig. XIX is a side elevation, and Fig. XX a front elevation, thereof.

I Throughout the drawings the same parts are arrows adjacent to the letters denoting the plane of section.

As shown in Fig. I, a row of chairs coinprises a series of independent standards 1, with seats 2, backs 3, and arms 4, supported bythe standards, the number of the latter being one more than the number of seats.

The standard, Figs. IV, V, VI, VII, and VIII, is preferably of cast-iron, as already stated, and all in one piece, with the exception of stud 5 and nut (3, and it stands upon the base 16. The thin central'port-ion or web 7 is stiffened at its edges by the rib S, which strengthens and improves the appearance of the standard. I 9 are sockets or notches 011 the sides of the standards adapted to receive the gudgeonsor pivots 10 of the seats. The web 7 is continuous between the sockets, (see Fig. VIII,) so as to preserve the strength of the standard and locate the seat-gudgeons 1O endwise, and it will be seen that as the sockets are open at the top, there being no rib at the mouths of the sockets, the seats can be simply dropped into place or removed without disturbing the standards.

11 are brackets projecting from the sides of the standards and adapted-to support the seats, which rest upon the tops of the brackets when turned down, as in Fig. II, and against the rear parts 11 of the brackets when turned up, as in Fig. III. The position of these brackets is so arranged in conjunction with the curved form of the sockets 9 that the seats rest quite securely in either position without any tendency to tilt.

12 is a bracket for carrying the arm, and 13 is a palm forcarrying the back. Each of these is pierced with the holes 14:, of keyhole form to suit the studs 1-5 of the arms and backs, by which the attachment is made.

The seats, backs, and arms each consist of a framework, usually of wood, covered with upholstery after the ordinary manner.

10, Figs. XII, XIII, and XIV, are the gudgeons already referred to and adapted to drop into the sockets 9. These gudgeons are firmly fixed in the framework of the seat, the width of which is such that it can swing freely between the standards 1.

15,Figs. XVIII, XIX, and XX, are the studs or button-head screws, already referred to, firmly fixed to the lower side of the arm and adapted to be dropped through the enlarged parts of the holes II in the arm-bracket 12 and then slid forward into the slotted parts of the holes, so as to attach the arm to the arm-bracket.

The back, Figs. XV, XVI, and XVII, is pro vided with a pair of studs 15, similar to those of the arm and adapted to similarly attach the back to the palms 13 by the holes 14: therein. A shoulder 17 is formed at each side of the back, which is intended to abut against the shoulder 18 on the standard 1 when the back is in its proper position. The lower edge of the back then lies behind the arm, as shown in Figs. II and III, and thus prevents the latter from being slid back, so that it cannot be displaced unless the back he first raised.

The correct distance between the standards 1 is determined at the top by the backs 3 and at the bottom by the light tie-bars 19, having holes fitting over the studs 5 and secured by the nuts 6. The tie-bar may be continuous for several chairs, as shown toward the left in Fig. I, or it may be in short lengths, as shown toward the right in the same figure.

As will be seen from Fig. I, all the intermediate standards 1 are alike, and the end standards only differ from the others inasmuch as the palm 13, socket 9, and bracket 11 are provided on one side onlyright or left, as the case may be.

In setting up a row of chairs it is only necessary to place the standards in position, attach the ties 10, affix first the arms and then the backs, and finally drop the seats into the sockets.

In place of the base 16, already described, a shallow bracket or socket 20, Figs. IX, X, and XI, is fixed to the floor by the lugs 21, and the foot 22 of the standard is adapted to be slid into and held by the bracket. In this construction the tie-bars 19 are of course dispensed with.

It will be noticed that by the construction described any individual seat, back, arm, or standard may be removed or replaced with the utmost facility without the necessity, which is experienced in the ordinary construction, of disturbing the remaining chairs of the row; also, that the standardsnot being fixed, as is usual, to the floor the chairs can be set up or their positions rearranged with very little trouble or delay.

With regard to the attachment of the arms and backs the main feature is that the attachment is made by simply placing the arm or back against the corresponding part and then sliding it into position instead of having to insert screws. The device shown is considered best adapted for the purpose; but obvious mechanical equivalents might be substituted. For instance, the arm brackets and back-palms might be of dovetail crosssection for a portion of their length, corresponding short pieces being attached to the arms and backs, so as to allow the attachment to be made with a small amount of sliding.

Ilavin g now fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In combination, a row of standards, each of which with the exception of those at the extreme ends of the row serves for two seats; seats provided with pivots and supported by the said standards; open-mouthed sockets on the standards to receive the seat-pivots; and brackets on the standards against which the seats abut when turned down or turned up; substantially as'described.

2. In combination, a pair of standards, seats provided with pivots and supported by the said standards, open-mouthed soekets on the standards to receive the seat-pivots, and brackets on the standards against which the seats abut when turned down or turned up; substantially as described.

3. In combination the standards and seat, arm-brackets on the standards and arms with means for fixing the same to the brackets by sliding the arms forwardly into position and means for preventing the retraction of the arms on the brackets, substantially as described.

t. In combination, standards and pivoted seats supported thereby, arm-brackets on the standards with holes ot keyhole form, and arms provided with studs 15 to engage said holes and afiix the arms to the arm-brackets; substantially as described.
