i Application filed December 13, 1920. Serial No. -9...;0,1 $196.` 'Y i i To all whom it muy concern:

Be it known that I, FRED' Gr.- PARKER, a citizen of the United States` residing at Patersom in thev county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Seating Appliances, of which-the following is a, specifica,- tion.

anccs and as herein shown has been designed as a seatingappliance 'for vehicles, whereji't I is desirable that-the seatshould haveup 'and down movement and be cushioned4 against downward movement and wherev its-supporting means should'take up aslittle-floor space l as possible, so as toallow lamplefootvroom, and yet should afford ample-basal dimension in the directions in which tilting forces areVV usually applied, and especially forward'and i back and laterally. v-

My inventionconsists incertain eombinaf tions of parts in a seatingap'pli'ance of the y class' in which a seat-including` means is movable vertically with respect toa supporting means, being cushioned in its downward movement, the object being to provide a Astructure of this class which shall be strong and durable in construction, inexpensive to manufacture, and efficient in operation especially in that its up andy down movements will be without friction or. binding.

My invent-ion further consists in a novel back and seat structureto behereinafter set forth. y

In the drawings, v Figure l visla front elevation ofthe nnproved seating appliance;

is a'plan,i the back beingv'reso that'its yextremities extend forward, givingl the angle iron an L-shape in side elevation. The angle of the angleiron is made to receive the rearward edges of the top and sides of the back and the under lateral edges ofthe seat, andissecured to the back and This invention relates to seating f'appli-Y l is a vertical sectionalfview of the seat by means 'of screwsclor. otherwise; y] In this way an inexpensive and'yet strong and,

f durable back-and-seat structure is produced.

Upright-e also contains a plunger lo which ,is substantiallysquarey in cross section and y is secured tothe `seat bottom]l (suchas boardsth'e seat' shownl being of the upholi stered type),1restingfon' the springv The plungerfc is vnearly l of the same crosssec.-

tionalarea'as the uprighte and in order to keepjits ,vertical movements therein true it has projections which travelvin ythe angles of said upright e, the said projections in the presentinstanc'e being parts formed indepenl' dently of the plunger `andthe uprightlin the i 'v present instance yhaving ways on which said projections travel which are also formed findependently ofthe upright. a That is ,to Say,

bearingplate's m are yattached to .thecorners of the plungerfc Ka'ndr'inthein are journaled peripherally'grooved rollers n; the ways're-- ferred to, ldesignated 0, .are'suitablelengths i of heavy wire each arranged ,at-an, angle` and within the upright,v extending vertically, and having its ,ends p rebent and clinchingthe upper and lower edges ofthe upright., The

lIh'er'e maybe an apronv of metal,

` construction is suchthat'theplungerinoves `up'a'nd'downwith'couipletefreedoml andyetl 1 undue lost motion laterally in4 ,any direction f is prevented.

' square in horizontal section, depending from y the seat bottom Z and housing -the, upper end .c of the upright @,thusgiving Ia finish to thel supporting means.r Als afurtherfineans to p guidethe structure including theseat, plunger 7c andapron g I may flatten out the. rebent upper end p of each track or way 0 and by an opening 7 formed inthe thusf flattened portion provide a bearing lfor a ball s which is kept in place by being backed by the upright e and by the outerend of the opening 1 being so restricted as to prevent` ythe escape of the ball outwardly, the ball being arranged to bear inthe adjoining ani gle of the apron g.

In the case of a seating appliance adapted for two or more occupants there will be a' lurality of the seat supporting means which have. above described in detail, these being arranged side by side.

The polygonal "form in horizontal section or the members c and 7c of the'supporting structure involves several important advantages: the angles of member e not only stiften this member but aiiord guideways `(themselves stiitened by their angular form) for the projecting portions kwhich are developed by ythe angular form 'of the plunger 7c; the angles of member e also form pockets or grooves'in which the ways 'or tracks o repose, when as herein illustrated the guideways are finished `with ways or tracks. Again, the polygonal form or the supporting structure for the seat'nialres it require the least amount ot floor area and yet be adapted to afford a stable support to the seat against tilting when placed, as in accordancer with my invention, so that the anglesthereof project toward sides of the seat;

,in the present case,y the seat vbeing four-sided and vthe supporting means square in horizontal section, the' latter is arranged with tw'o'opposite angles vthereof projecting toward the front and back of the seat and the other'two angles projectingtoward lateral i sides of the seat. This arrangement, more- Letter Patents 'isz-jover, aifords'aniple oot'room, which is especially desirable where thefseating appliances are used in a bus or other vehicle and front ofthe other. f y

If the member g isformedas herein set forth fot stiff material (although it need not necessarily beformed or such material) it will. serve Ato assist in guiding the seatincluding structure, as .for instance as illustrated in Figures 5 and '6.

To the under' side of the block forming the plunger 79 a:l gasket or equivalent 7c is securedl by screws Ic so vas to sc'al ott from above VKthe'space therebelow. and make the plunger in efect a piston, so that the seat will rest in part on a pneumatic cushion.

Having thus fully described my invention,

are placed more or less close together, one in vwhat I claim as new and desire to secure by if. A seating appliance ycomprisi'n opposed means including receiving and received' telcscoped membersone kof said means including a seat and being movable up and down and the other supporting the first means, and the receiving member being inwardly angular in horizontal section and the received member having guiding projections extending outward of the general cross-sectional contour thereot' and received in the angles formed by the receiving member.

2. A seating appliance comprising opposed means including receiving and received telescoped members, one of said means including a seat and being movable up and down and the other' supporting the iirst' means, and the receiving member being inwardly angular in horizontal section, and ways reposing in and eX- tending longitudinally of the angles and engaged by the receiving member.

3. A seating appliance comprising opposed means including receiving and received tele-- scoped members, one of said means including a seat and being movable up and down andthe other supporting the rst means, -and vertical attenuated pieces having their upper and lower ends rebent over and thus secured to the upper and lower endsV ott the receiving member and 'forming guiding means for the received member.

4j ln combination, a seat-including structurehaving a downwardly projecting plunger, a hollow upright formed substantially polygonal inhorizontal section and receiving the plunger and adapted to rest on a suitable base, the plunger having projecting portions guided in the angles ot said upright and said uprights being arranged with the angles thereof projecting toward sides of the seat, and a cushion device within the upright against which the plunger bears downwardly.

flrn combination, a seat-including structure having a downwardly projecting plunger, and a st id"y apron surrounding and spaced from the plunger, a hollow upright structure receiving the plunger and received at its upper end by the Aapron and adapted to lrest on a y*suitable base, and a cushion device within the upright against which the plunger bears downwardly, said upright structure affording inwardly a guide to the plunger and outwardly a guide to the apron.
