This inventionrelate's to impro'vementsin bases l for stools and other articles of furniture. J
In certain '5 improvement on thatdisclosed in my U. S.

Letters Patent, 1,453,650, granted May '1,
1923. That is the presentinvention contemplates, and has for an object to provide,
. a base for any article of'furniture which E p p v form and easily assembled. The stoolcom: any
by screws 11, to a I suitably fixed to the upper end of a post 13 7 base canbe shipped in-knocked downt form and assembledwithout the: use of I too-ls; The parts otthe'baseja-reheldftoQ gether -without theuse of pins,screw's, bolts, lorthelikefandare so interengaged as to be self sustaining. l l r In another aspect, the invention contemplates, and has as object to provide, an im-; proved base which will fh'averesilient qualities andthis feature of the invention isespecially applicable to stools and like'articles which are, used to sit upon. 'In connection-with the resilient base conthe resilient movement andsuch means may .be in the nature offixed stopsor the result may be obtained by applying a braking action tothe downward movement of the v fl standard, or both these forms may be' used U :colnjointly, the braking action serving-to gradually arrest the downward movement to Fig. 2- and illustrating modifications'in 2"- andwitha'downward slope. These open-x ings ireelyreceive the free ends of the up-, 5
and cause lessabrupt engagement withthe stops. r

disposed in the same vertical,planefl The Wer 4 upturned,substantially. vertically, as indicatedf at 26., The member :20, which is slid'ablyf engaged .in standard' ly is provided with a ser'ies of radiatingfhubs 27,-inj which are formedopenings 28 lead:
ingmfrom' the bore 21 radially outwardly per arms 2%; Below the openings 28, an]
equal number of vertical slots 29 are provided in the member 20, which slots are large enough to permit the upturned ends preferably '26 of the lower arms to be'passed there.-
through into the bore 21, as illustrated in Fig. .4. Pre'ferably,the ends 26, when thus brought into grouped relation, have their upper extremities slightly outt-urned, as illustrated in somewhat exaggerated form in rig. 4. The lower end ofstandard 14 is interiorly" ta aered, as at 30.
" -Th e' parts, when positioned as in Fig. 4, are
finally 7 V the standard 14, the bevelled end camthese ends 26 into the open connected-together by forcing down upwardly, firmly grip the interior wall of standard, it depresses arms standard 14, whereby the parts cannot readily loosen and fall apart when pressure on the standard is relaxed. I
The normal positions of the parts, urvsembledas described, is shown in Fig. 2 and it will be. noted that the slots 29 ex tend below arms 25 to an appreciable extent. With this condition in mind and bearingin mind that standard 14 is capable of freely sliding in member 20, it will be seen that when weight is applied to the 25, which flex about the floor engaging parts 28, as fulcrums and the weight is balanced against the resiliency of these arms,giving a spring support for the standard. The upper arms 24 act as struts to support the member 20 from the floor during the action described. It is desirable to limit the degree of ore of the lower arms. 'Ot'herwise, an, abnormally heavy loadon seat 10 might cause the arms 25 to flex beyond their elastic limits and break. For this purposel provide closed lower walls for slots 29, forming stops 32 against which arms 25' may abut to limit the downward movement of standard 14. As another means of arresting the downward travel of standard. 14, the end faces of the free ends of arms 24 may be allowed. to have access to the outer peripheryof standard 14. With this arrangement, the downward fiexure of arms 25 tends to'force the end faces of arms 24 against the standard 14, and the frictional engagement acts like a brake to retard the downward movement of standard14. The end faces of arms 24 preferably have portions 33, which are parallel to the axis of standard 14, so that these faces rub against, rather-than dig into the standard. Desirablythe stops and braking. means are used in conjunction, the latter serving to retard the downward movement of the standard as arms25 approach stops tions.
32. In this manner an undesirable abrupt termination of the downward movement of tumers, taborets, stands and the like articles of furniture, the same construction may be used except that the slots 29 are decreased in length so as not to extend materially below arms 25 in their normal unflexed posie This condition is illustrated in Fig. 5 andthe constructionthere shown haspall the. desirable features relating to simplicity of constructionand ease of assembly of parts, as the construction already described; \Vith the construction shown in Fig. 5, the end faces of'the free ends of the upper arms 25 may be bevelled, as at 34, so as to dig into thestandard 14 when weight is imposed thereon, asdescribed in my priorpatent, above identified, whereby an extremely rigid base vconstructionis provided. a
in Fig. 6, I have illustrated another consupport may be had without the use of the stops or the braking effect. struction the member 20" is formed in much the same manner as disclosed in the above identified patentbut is freely slidable on the standard 14. The openings 28, which receive the free ends of the upper arms 24 do not extend entirely through the'member 20 and they consequent y do not exercise any brakin ment of the standard 14. The member 20" terminates 'short of the lower ,end of the standard and arms-25 pass below, but not through, the member 20. The free endsof arms 25 are, however, upturned and wedged, into the lower open end of standardrl4, in the above mentioned prior patentl In.
In this. coneffect on the downward moveoperation, the weight on, standard 14 depresses it and causes arms 25 to flex in the same manner, as already described.
It is not necessarily essential that the upper arms 24 be connected to a separate menn ber, such as the casting 20. The. essential thing is that some means be provide'd atthe ends of such arms which will permitthe standard 14 to move downwardly relatively.
ment shown in Fig. 7, the lower end of st d 5 ard 14 would be provided with notches 87 in which the lower arms 25 are engaged to locate and space them angularly relatively to the standard.
The base construction describeddis such that'the several'partsmay be "readily;v
conveniently assembled without the jnse of tools. :Indeed, the entire stool construction is designed with this end in View andtno more thama screw driver'wou'ld'he -required to fasten the seat 10 to braciketlfl, The Stool may be shipped in compact knocked down form and easily andquickly assem' bled when required, The constructioniof' stool is also such as to lend itselfto quantity production at low unit cost. r t
The spring base constructionnis a most desirable feature in stools and thelike,v as distinguished from arigid base; "Whenone sits down on the seat 10, it yields gradually until the weight imposed on the seat is balancedby the force of the springarms 25. The practical elfect is the same as when one sits down on a soft yielding cushion and the yielding feature addsconsiderably to the" merits of the stool without adding'to its manufacturing cost.
