UNITED STATES PATENT OFFICE.

METALLIC CHAIR, STOOL, SEAT, ANI) THE LIKE.

Application led January 19, 1924, S.eria1 No. 687,184, and in Great Britain September 18, 1923.

This invention relates to improvements in chairs and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The primary object of the invention, is to l provide a strong and rigid chair especially adapted for use in factories and similar places and which is so constructed as to ably withstand the rough usage! to which it is naturally subjected.

A further object of the invention is to a work bench or. similar factory equipment so as to be out ofthe-way when not cfccupied.

These objects of the invention as well as the many advantages thereof will more fully appear as I proceed with my specification.

Fig. 1 is a view in perspective ofa chair embodying my invention.

Fig. 2' 1s a view in side elevation ofthe same.

Fig. taken on the line 3-3 of Fig. 2.

Fig. 4 is Ia detail vertical sectional view thru Fig. 3, as taken on the line 4- 4 thereof.

Fig. 5 is a detail sectional view taken'on the line 5-5 of Fig. 2.

Referring now in' detail to that embodiment of the invention illustrated in the accompanying drawings ;10 indicates as a as will later appear.

vThe base or pedestal includes two vertically spaced, metallic collars or spiders 14-14 having arcuately spaced vertically extending rounded recesses 15, in the periphery thereof. In said recesses are seated, the top ends of tubular metallic leg members 16, screws passilgsthrough said leg members and extending into said collars to securely attach said leg members thereto. The bottom parts 17 of said leg members are bent outwardly 3 is a horizontal sectional view as.

to provide a large spread for the legs so that the chair Cannot. easily tip over and on the extreme bottom ends are suitable antifriction members or casters 18 so that the chair as a whole, may be easily moved about upon the floor.

'19 indicates a tubular lpost or standard which has a rotative bearing as well as a vertical adjustment in centrally disposed aligned openings 20 in theI collars 14. As show'n herein, the post or standard 19 has a plurality of vertically spaced setsof holes 21 therethrough and a pin 22 is employed which may be'inserted through any one Setof holes and to rest or bear at its ends upon the top collar 14' to provide the desired height for the seat 11. As is apparent this adjustment may be quickly and easily made,

and to prevent loss ofthe pin I connect it to 'a part of the seat 12 by means of a chain or other flexible .member 23, as Will later appear.

To the .top end of the standard is secured laterally extending arms 24 (see Fig. 2) which are attached to the seat 11 in any con- .venient manner, so as to support the same side ofthe horizontal flanges of the angle bars 25 midway 'between their ends and on the top side of said langes is secured the lateral margins of a iiexible seat member 28- by means of metallic straps 29. Said seat may be of thecushioned type if so desired or it may be madeof a strong textile material such as canvas. The, front end frame member or bar 26 is bowed downwardly between its ends so as not to be engagedby thev legs of the occupant which would render the chair uncomfortable to sit upon. To the rear end ramemember 27 is attachedthe pin chain 23 and depending from said frame member isa rod 29 which terminates in an co may be secured at their ends to the underupturned hook end30 :toria purpose to ap- 36 to receive the back of the occupant.

metallic straps. Said arms are offset inwardly midway between these ends so that the top ends 32 thereof are closer together than are the bottom ends 33 which are spaced apart a distance slightly greater than the width of the seat frame. The arms 31 are connected together just above their olf-r set portions by a brace strap or band 34 and to the top ends 32 of both of said arms is connected an outwardly bowed bar 35 which carries a similarly shaped back rest member This rest member may be padded or cushioned if so desired.

rlhe bottom ends 33 of said arms are operatively connected to one end of a pair of links 37 by bolts 38, the other ends of said links being pivotally connected to the front ends of the seat frame side members 25 by means of similar bolts 39, the said last mentioned bolts also extending through the bent over ends 26A of the front frame member 26. The bottom ends 37 of the arms 31 and the associated ends of the links 37 are provided with spaced openings 4() and 41 respectively,

any two of which may be brought into regy istry with each other to receive the bolts 38.

In the upright flanges of the side member 25 of the seat frameare provided spaced holes 42 into anyone of which the bolts 39 may be threaded. By reason of the provision of the holes 40--41 and 42 as before described, 1t is apparent that any desired angular position or adjustment of the arms 31 and back rest member 36 may be obtained.

On the inner surface of each of the arms 3l just below the offset therein, is riveted a plate 43 (see Figs. 2 and 5) which includes .an odset portion adapted to engage upon the top edge of the bent over ends 27A-27A of the rear frame member 27. The offset portion terminates' in a hook-like portion 44 and the purpose of which will shortly appear. These plates 43 support the arms 31 upon the seat frame under the pressure applied to' said arms by the occupant of the chair when leaning back against the rest member 36. When it is desired to lift the chair by the back, an upward pull causes the hooked end 44a to engage the rear cross member of the seat frame 27, thus lifting the whole chair.

Whenv it is desired to lower the back rest member 36 until the arms 31 are in the po cross member of the seat frame and then lifted upwardly to release the offset portions 44 from engagement with the seat. frame. This movement of course, is accommodated for by the links 37. Further backward and downward movement is next imparted to the back rest .member whe-n the hooks 44 will clear the seat frame after which a forward movement isy imparted to said` member until the brace bar 34 engages the rod 29 before mentioned. Upon release of the back rest, the same will move downwardly under its own weight until said brace bar engages the hook 30 to retain the back in this lowered or folded position.

By reason of the arm and link Iconstruction before described, it will be noted that there are no obstructions at the sides of the seat member l1 which will interfere with the free bodily movement of the occupant of the chair.

The chair being made yof substantially all metal, is strong and rigid and therefore, withstands such rough usage to which it may be subjected. It is especially adapted for a work room chair and the back rest may not only be quickly and readily adjusted as to angular position, but said back rest may be folded down so that the chair maybe stowed away, as before mentioned.

lVliile in describing my invention, ll have referred to certain details of mechanical construction and arrangement of the various parts, l do not limit myself thereto except as may be pointed out in the appended claims. 1 I
