JOHN CARRING'ION BROOKE,` OF CINCINNATI OHIO.

ASSEMBLY-CHAIR.

Specification of Letters Patent.

Patented June 2, 19078.

Application led March 1, 1907. Serial No. 360,014.

To all whom it may concern:

Be it known that I, JOHN CARRINGTON BROOKE, a citizen of the United States of America, and a resident of Cincinnati, in the v county of Hamilton and State of Ohio, have invented certain new and useful Im rovements in Assembly-Chairs'l of which t e following is a specification.

My invention relates to improvements on those'assembly chairs in which the seat is adapted to fold and the back is adapted to be tilted forward to facilitate the seating of an audience by providing additional room between the chairs for persons to pass in and out and at the same time enabling the chairs to be placed nearer together and thus increase the capacity for seating in a room in which they are set up.

One object of my invention is to provide an assembly chair with standards of sheet steel construction and which may be simple or elaborate according to the idea of the user While comprising but few parts.

Another obj ect of my invention is to provide a light inexpensive plain and durable two part sheet steel standard including the supporting base.

Another object of my invention is toprovide a vertically adjustable seat arm support.

Another object of my invention is to proj vide an improved arm rest bracket.

Another object of my invention is to provide an adjustable pivot support for the back.

Another object of my invention is to provide an improved and durable link connection between the seat and the back.

Another object of my invention is to provide an improved construction of side frame for a tilting back.

Another object of my invention is to provide a vertically adjustable hat guard suport.

p Another object of my invention is to provide a vertically adjustable foot rest or rail support.

ith these and other objects in view to perfect such chair my invention consists in the novel features of construction hereinafter described and claimed.

In order that my invention may be fully understood I will proceed to describe it with reference to the accompanying drawing, in which y Figure 1 is aside elevation of my implroved assembly chair having a straight cus ioned back and a cushioned seat arranged in normal seating position. Fig. 2 is a vertical section thereof in folded condition taken on the line 2-2 Of Fig. 3, a portion ofthe seat cushion being broken away. Fig. 3 is a front view showing similar chairs of twin construction in folded condition.

which a plain standard, transversely curved plain back and a curved plain -seat are employed, the adjustability of the seat arm support, and the hat guard support being shown in dotted lines. showing similar chairs of twin construction in folded condition. Fig. 6 is an inside view of the plain standard, the adjustability of the foot rest socket being shown in dotted lines. Fig. 7 is a horizontal section of the arm rests between the twin chair backs taken on the line 7 7 of Figs. 5 and 6. Fig. Sis a detail side elevation of the lower part of the standard and its base plateshowing the lower end as shaped for an inclined Hoor.

In carrying out my invention I provide a pair of plain skeleton thin metal standards 11 which are preferably made of. sheet steel, Wrought or malleable iron or cast steel, each having a substantial supporting base 12 pro# vided with broad feet 13 secured by fastenings 14. These standards 11 are reinforced by marginal flanges 15, and are further provided with foot rest rail sockets 16 and hat guard supports 17;

18 are seat arm supports or bracket arms formed on the standards 11 to which the seat arms 19, carrying a seat 20 having a plain cushion 21 are connected by hinge joints 22 similar to that shown in Patent Number 707 ,547 'issued to Finley S. Brooke, August lframes 29 each of I-shape in cross section and formed with lower and upper lateral proj ections 30 at right angles thereto, andhaving bolt holes 31 through which fastenings 32 are inserted for securing the back or panel to the side frames 29. The upper ends of the side frames 29 are curved rearwardly to provide pockets 33 in which the u per curved edge 34 of the back panel 26 is tted to pro- Fig. 4 is a side elevag `tion showing a modified construction in Fig. 5 is a back view vide a partial support to the latter. Each.

side frame 29 is also formed withy an outwardly and forwardly projecting lug 35 having' a bolt hole 36, receiving a pivot or hinge pin 37 mounted in a bolt hole 38 formed nl the offset outer end 39 of an. adjustable curved plate 40 fitted and slidable in the curved slide recess 24 between the horizontalY curved flanges 23, having a horizontal bolt slot 4:15 withy which the bolt hole 25 ofthe slide recess 24 registers.

42l is a clamping bolt extending through.

of the side frame and having'a pivot-hole 45.. Formed upon the-outer side of the seatiarm 19: isan' outwardly tapering.` horizontal tubular stud. 46.

47 is ay connecting link. hinged: at its forward.` end: to a pivot-bolt 48eXtending through theV tubular. stud, 46 and securedby a. nut 49. rI-he rear end ofthe connectinglink. is hinged to the back. arm 44 by a pivot pin.. 50..eXtend; ing through pivot-hole45.. By this connection when either the back is thrown; forward.

or the seat lifted thesemembers will assume a: vertical position within. the bounds of the standards.

rllhe upper ends 51 of the standards 11. are soformed as to provide armrests which may be provided' with supplemental rests 52.I suitably connected: therewith by fastenings 53'.

54 is a foot rest railsupportedin the socket 16 and secured by' fastenings 55 tothe end. standards 1 1..

56 is a hat guard strip or rail mounted in its'supports 17 and secured: by fastenings 57 to the end standards 11. 4

In Figs. 4, 5, and 6I show my preferred form of standard. 11a is athin plairr rec.- tangular vertical plate ofy malleable east sheet steel and 12a is a supporting base plate formed with arecessed marginal flange receivingitheplate and riveted: thereto and having broad. feet 13a secured by fastenings 14a. 18a isa seat arm located in the same place as thestandardz and having an offsetinner part adjustably secured to the standard 111a by riveting it thereto. 26a is a transversely curved back to which the side frame 44EL is suitably secured by fastenings 44?. This sidey frame 44a carries the outwardly forwardly projecting lug 35a whichisconnected to the curved plate '40. 51;a are offset arm rests inthe form of brackets located in the same plane as-the standard and carrying the curved fianges 23 and are riveted tothe standard 11a. 16a are the socketsA for supporting the foot rest rail 54 adjustably riveted to thestandardf 11, and 17a are offset hat guard supports located in the same fplane asthe standards and adjustably rivjustable the seatscan be placedi at any height from` the fioor thus providing seats ranging from 12 to,I 18inches high.. Where the foot rest sockets are made adjustable it has advantage of locating the rest rail: at the proper height.. vThe hat guard' supports when ad:- justable upv anddownican be arranged to suit different kinds of seats.

thus described. my invention the following is what I claim asnew therein and: desireV to secure. by Letters. Patent:
