This invention relates to tip-up and like chairs and has for its object to provideimproved "means which, while complying with municipal requirements, automatically acts to tip the seat into the tip-position when the seat is not in use.

According to the present invention the op erating part of the tip-up mechanism is asso*' ciated witha side standard or upright or with an adjacent part of the seat. The seat is adapted to be supported by and between standards or uprights, one upright or standard being provided with meanswhich' is is placed under compression'when'theseat Y is lowered and which, 'when the seat is freed from the load automatically acts to tip the seatiinto the up position. An upright or standard is-provided with a hollow drum or casing as an integral or detachable portion thereof- The hollow drum orcasing is pro- I vided with an interrupted circular recess to contain afhelical springone end of which abuts against the end of the said recess,- the other end of the springbeingarranged to abut against a stop or projection provided on a disc which may besuitably attached to or form an integral part of the seat. The said disc may be provided with a further projection which may be arranged'to co operate with a suitable projection in the interior of the hollow drum or casing so as.

to retain. the seat in the down position. The outer projection on the aforesaid disc when the seat is lowered acts on the resilient member and-compresses the latter. When the 7 seat is relieved of pressure or load the spring automatically acts on the: said projection on the disc and tips the seat into If so desired the outer the up position. face of the hollow drum or casing may be provided with a stop on which the adjacent seatbears or rests when in the down position. Further, the opposite standard may .be provided with a stop or projection to cooperate with the stop or projection on the outer face of the hollow drum or casing so that the seatlmay be supported when in the down position by both stops.

In order that the invention may be clearly understood reference is made to the acc0m' panying drawing which shews by way of example a construction of tip-up or like chair in accordance with the present invention. I

Figure l is a side view of part of a tip-up the inner face of the'disoi g It is of and like chair in' accordanceWlt-h thePres ent'invention.

Figure 2 is awfront view. Figure 3 isan interior .view'of-the hollow drum or casing hereinafter fully described; and Figure .4 is an elevation of the'di'scwhich is attachable .to and detachable from the seat itself, the said elevation showing In the general arrangement of the parts s-hewn in Figuresl and 2 the standards or 7 uprights are indicated at 1, 2. The hollow drum .or-casing is shewn attend the seat. is shewn .at 4. The hollow drum or casing is provided witha circular recess :5 to con= tain'a helical-springfi one end .7.-of-lwhich abuts-against the wall 8 of the circular -re-.

cess, the other end 9 of the spring abutting"- against a projection 10 on adisc 11 which 7 is attachable to and detachable from the-seat 4. f desired the disc 11 may be formedas; an integral portion of'the frame of theflseat.

ing is provided with a stop-=12, which (30-; operates with a projection 13' to support the seat when in the lowered.p'osition. The. seat may be supported. on a spindle or plate 14 passing: through the disc andfalso through thehollow drumior casing, the otherend 'lfi ofthe spindlebeing supported bythe hollow druiinor casing and if so desired, in a .bear- '45. The interior of the hollow drum or cas- .ing-secnre'd to the adjacent seat; The outer face of the hollow drum or casing may be provided with a projection 16 which in coni. junction with a projeeti0n-17 on the Opposite standard acts to support the seat 4 when inv I the down position. jec-tions 12 and 13 in the hollow drum or casing and the disc 11 respectively may be" omitted and the projections 16, 17 used instead or, if so desired, bothv sets of projecvtionsniay be used.

, The action of the device is as follows, it i being assumed that the disc 11 is rigidly secured to or forms an integral part of the seat 4. When the seat is tipped down the pro- If so desired the projection 10 which abuts against theend9 of v the spring'compresses the spring 6 against the bottom '8 of the circular recess 5. On. releasing'the seat the spring 6 acts'on the projection 10 on the disc 11 and rotates the disc and consequently the seat i which is] thus tipped or rotated on its spindle orgwith' its spindle into the up position. f course to -be understoodthat while 1. A tip-up chair including aspaced standards, a seat supported by and between the standards, a casing mounted on the casing is shown on the standard and the disc on the seat, the reverse arrangement without change in the detailed structure is within the spirit of the invention.

That I claim is Z',

pair of I one of the "standards and disposed approximately midway of the frontand back of the standard with which the casing is associated,

a helical spring arranged in the said casing.

a projection carried by the seat and adapted between the'said standards, a casing integral the seat as it is being lowered.

. to move therewith so as to engage and etiect shortening of the length 01. the spring as a whole and as the seat is lowered, a second.

portion thereof, an arcuate recess provided in said casing and a helical spring inserted into thesaidrecess, a projection carried'by thesea't and adapted to engage and reduce thelength of the helical spring as the seat islowered, said recess having an abutment to be engaged by said projection to limit movement of the seat as the latter israised by the-spring, and cooperating means onthe casing and seat to limit the movement of 3. A tip-up chair comprising a. pair of spaced standards, a seat-supported by and with one of the said standards andprovided in its interior :with a? projection, a helical spring mserted in an arcuate recess in thesaid casing and having one of its ends abutting against a portion extending radially acrossthe saidrecess, a disc carried by the seat, a pro ection on thesaid disc adapted to engage the free end of the helical spring and to reduce the length thereof as a whole on the seat being lowered, a second projection on the said disc adapted to cooperate with the inte "ior stop in the said casing so as to limit the downward inovementof the seat.

4. A. tip-up chair comprising relatively movable elements as a'sta'ndard and a seat, a casing mounted on one oi the elementsand formed with an annular channel and with astop inwardly of the channel, a helical spring seated in the channel, a disc carried by the other of said elements and having a projection to bear against one end of the'spring and longitudinally compress the same in the relative movements of the elements, said disc having an additional projection to cooperate llth the stop on the casing to limit relative movement otthe elements.

5. A tip-up chair comprising relatively movable elements as a standard and a seat, a casing mounted in one of the elements and formed'with an interrupted annular channel having a fixed terminal abutment, a helical spring housed inthe. channel with one end bearing against the abutment, a disc carried the other of said. elements, said elements cooperating itor' relative rotary movement.

means carried by the disc to seat in said channel and bear'agalnst one end of the spring to longitudinally compress the same in the relative'rotary movements'ot the elements, and cooperatingmeans on the disc and casing to limit the relative rotary'n'io'vements of these elements in one direction.

In testimony whereof I have hereunto signed 'my name.
