Kivoorrnown CHAIR.

Specification of Letters Patent.

Patented .rune 2s, 190e.l

Application filed July 29, 1907. serial no. 385,953.

'To all 'whom it may opneemt: l y Be it known that I, JAMES R. KOEN, a citiin the county of Erie and State of New York, have invented a new and useful Improvenient in Knockdown Chairs, of which the following is a specification. l

rlhis invention relates to a knock down ,chair or stool designed more especially for use-on launches and as an extra seat for automobiles but the same is also desirable in' stores and other places.

The object of my inventionxisl the production of' a comfortable and inexpensive chair 'of this-kind in which the seat. pedestal and 'base can be readily disconnected lto permit the parts to be stored, packed or shipped' in a small compass.

In the accompanying drawings: Figure l is a vertical section of a chair embodying the invention. Fig. 2 is a similar section at right angles to Fig. 1. Figs. 3 and 4 are cle- -vations ot the upperportion of the pedestal viewed from opposite sides.

Similar letters of reference indicate corre j sponding parts throughout the several views.

-. g A indicates a base late screwed or other? wise secured to the Oor and having a depending socket A- arranged in an opening in the floor. This socket receives the lower endo' the seat-supporting post or pedestal "BA which is hollowv and preferably constructed ol' tubing. The post is removably seated in this socket and locked therein by a spring catchfpreferably bentv up of a single piece of Wire and composed of a coil c 'supported on a transverse pin or rivet d passing through the postB and having arms orbranches c1, c2. One ofthese arms is provided with a head or shoulder` c3 which extends beyond the lower end of the post and interlocks'with the lower v end of the socket A1, as shown in Eig. l. The

two arms -of this spring-catch are seated in notches e formed in the lower end ofthe post on opposite sides thereof, whereby they are held against twisting or lateral displacement.

The cross-pin d projects beyondthe sidel of tiepost at one or both ends and is located -i A niediately above the base plate, so that itforms a stop which limits the-.downward ni vement Oi' the post in the socket A1 in a dition to serving as a support or means of u attachment for the spring catch. f F indicates a suitable seat detachably buntedon the upper end ofthe postand preferably provided' with, a folding back a sprir'rgv-catc The may however bezrigidly secured to the seat, or omitted, if` desired.,v To the underside of the-seat is secured. a; socket H which receives the upper end of the post and which is removably locked thereon by a" spring catch which may be offthe'same construction as the-lower catch/except 'that it reversed, i indicating the coil o`f said u per catch, t, i2 the arms of the spring, i3A the cad orshoulder which interlocks with the upper or inner end of the'socket Hand j the tran'sverse pin by which the catch is attached to ost 'areV ta ered to facilitate their entrance into the soc ets of the base plate and the seat. f

lAlthough the catches formedv by the headed arms cv and t" do not positivelylockthe seat upon the .post and the latter' in the base plate A, yet vthey keep these parts inter locked frictionally` with sufficient security to prevent their accidental separationv or detachment. At the saine time, the' parts can be readily dismembered by a sufficient pull to deflect the spring-catches out "Of en sgae i ment with the sockets ol the-seat an -t base-plate. Upon thus detaching the post from theiioor and the seat from the post, the

parts can be compactly stowed away or con-` veniently transported. 'f'

In its normal erected position, the chair is free to Vfotate, as the post is capable of turning iu its socket and the seat is capable of turning on the post.

I clainas my invention:

1. A -chair,comprising a seat its underside with a socket, an apost or pedestal arranged inA said socket'and provided nearits upper end with a pin arranged toforrn esto o1'. support for s ai socket, and
