` My invention relates particularly togliders adapted tobe applied to furniture tosupport thesame. f y f. .fg

` The object of my invention` is toprovide gliders of an improved type, adapted to be applied to portions of furniture forthe support vof thev same, and ywhich are adapted to support the furniture while eliminating noise to a maximum extent when moving the furniture from place to lace. Glidersmade in accordance with myyinvention 1 are capabley of being applied to'anyportion ofanyfkindof furniture to supportthesame, but are applicable especially to kthe legs orfeet of chairs,

tablessettee's, etc. v vj f Hitherto gliders provided forjsupporting furniture have had many disadvantages-' As originally made,such gliders `were comprised merely ofa large metal head havinga stem adapted to be driven into thefurniture at the point of supportand with no means Whatever forabsorbing (shocks between the furniture and the glider. yAs a result, in such construcf tion, the movement of `the, krfurniture over 25 floors, andparticularly inthe ycase of Avery hard floors, such as ythosewinade ofgmarble, stone, concrete, etc., caused .a r` eat deallof noise. v,This is averyundesira 'le effect, es# pecially in thecase of large rooms or halls Where a large number of'chairs are being ymovedfat a given time, as-will be readily understood. 1 Attempts Vhave beenA made at the time to absorb all shocks between the gliders andthe furniture but in those constructions a number of .disadvantages have developed.

Such f previous constructions have had such a tight union between the? glider .and the article of furniture as to transmita" considerable amount of .noiseunder [certainc'irf40 cumstances when! moving `the-furniture.

Furthermore, in vsome instances the-construektion .was suchy as not l to effectively hold fthe glidergcap, which4 contacts 'with thev floor seb curely in position so thatsuch caps :ofttimes became dislodged and destroyedtheeffectivestances, in previous constructions, in ,the-en- 1; -While my invention is capable dtvof secuie'th cap'tighuy in' piacea f has been found necessary .to makethe cap of nitureto be moved. Also,vsuch soft metal` cOIlStructions have been foundfto make decided marksjon' some Hoor-coverings, such, for example, asflrinoleum.. Furthermore, in the yeffortfto hold such caps in place it has been found thatthe material contained ytherein has y become ypacked k-so tightly-as to prevent a resiliency such as is necessary-tojprevent kthe making of unnecessaryA noises-when ymoving they furniture. i 1

`The object 0f my invention iS, therefore, rto,y i,

avoid these difficulties. Especially, it is one of myobjects to hold the stem` in permanent union kwith the ,cap but with a loose connection thereto so as topprovide an amountk of free playbetween the` stem attached to the furniture and the capv secured thereto,'soas to enable a maximum resiliency to beobtained by ,reason of the interposed body of `resilient material located. between the furni-y ture and the-cap supporting the same. l A furtherobjectis to permit in this manner, not

only a resiliencyin a vertical directionbe-y tween the-furniturefand the cap,-but1in a lateral direction as well. lA 'resiliency in the lateral direction .is important as rit has been yf(, 1.lndtha`t shocksffwhich might be 'transmitted jlat'erallybetween the glider and the furniturein sliding the; lattery over the floor, v y

, In the opera-tiori of my invention, referring first', 'to'the' termoli; my inventions shownr in Figures l to 3, it will be understood glider is attached to the furniture, as, for example, the leg of the chair 8, by driving the stem 4 into the same,fthe spring 2 being formed to press at its center against the inside of the cap so as to hold the head 5 against the cap l. This can be done eithervvith the parts.' assembled or withcthe cap removed followed b vthe final applicationy of the cap l-totheremainder of the construction. Howerera.it1SrPfe1sreb1y t0 apply the slider to the furniture in Y Completely assembled onrn, especially as it is desired to have the rubber Washer 'rnore or less tightly clamped betweeirthefeap land the leg 8 of the chair. This is for thepurpose, as pointed out above, of causing the furniture to become supported irrnly from theleap' 1', wh-i'uh.y i'sin turn' supported from the Hoor, and, also, so aste-'provide aafirm position for the furniture which is cushioned, not' only in a vertical direction from the cap v l?, but,`aljso, in a lateral direction Y dueV both to the loose connection between the stein 4 and the cap 1, and between the inn'e'rcoilsof' the spring 2 withregard to theeap'l. i

` When' the 'article of `furniture', as', for eX-v ample, acliair'-, is being'slide overaiioor, it

Wiljl be: seen that there is-an edective cushioning between? the furniturefand the capY l, due to the rubber Washer 7, thus eliminatingnoise which would otherwise result. Alsofor the reasonszjust explained', anyr tendency of the ItoE resistmovement' `laterally and' thus produce noise, Will be compensated for by reason of' the cushioning e'ectvbetween the capI l' andthe legi V81 "of the chair. This is veryy importantes ithas'beenl foundthat such later-all' resistance on the part of movement of the capproduces verticaly component, ref sultingin afgreat deal of noise unless thel construction is such as to eliminate the saine.
