ANDREW T-` PETEBSEN; lOF COLORADO SPRINGS.. GOLQRADO, ASSIGNOR or ONE-.HALF To TrioMAs a. rain, or' cononnnosenmes COLORADO.
T0 all fije/mm it may concern Be it knownthat I, ANDREW T. PETERSEN, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented new and useful Improvements in Glide-Casters, of which the following is a specification.`
The invention relates to furniture casters, and more particularly to the class of glide casters for use in furniture.
The primary object of the invention is the provision of a ycaster wherein the tread thereof is constructed to prevent the scratching of the flooring or foundation when supporting an article of furniture, and which will enable the latter to glide thereover so that the article of furniture can be conveniently moved from one point to another irrespective of the unevenness in the flooring or foundation, and also which will obviate the wrinkling of a floor covering should the article of furniture be moved thereon.
Another object of the invention is the provision of a caster which can be readily fastened in an article-of furniture so as to prevent the dropping of the castor therefrom when the article of furniture is lifted,
yet the castor proper can be readily detached from the article of furniture without necessitating the removal of its holder there- A further object of the invention is the provision of a caster Which will readily glide over a floor or foundation whether having a polished or roughened surface, and which Will obviate the marring'or scratching of the iioor or foundation when the article of, furniture supported by the casters is being moved, the castersbeing of novel `construction to permit the automatic adjustment thereof in event of unevenness in the flooring or foundation, and the ready mounting thereof in position 1n an article of furniture or removed therefrom, the holder for the4 V caster being constructed to permit the convenient fastening of the same in the `article of furniture so as to avoid the possibility of the dropping of the caster or its holder Whenthe'article of furniture is lifted. Y
` A still further object of the invention is the provision of a caster of this character i A which is extremely simple in construction,
reliable and eilicient in operation, strong,
durable, and inexpensive inmanufacturel With these and other objects in view, the
Specification olf Letters Patent. Patented Sept, 28, Application filed June 3, 1914. Serial No. 842,213.
invention consists in the const'ructiom combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.
In the drawings :t-Figure 1 is a fragmentary vertical sectional Viewl through the support of an article of furniture, showing the caster constructed in accordance with the .in vention mounted therein. Fig. 2 is a vertical sectional view through the caster.` Fig. 3 is a perspective view of the holder, Fig, 4 is a sectional View on the line 1 -lof Fig. 2. Fig. 5 is a View similar to Fig. l, showing a modified form of caster. Fig. 6 is a vertical sectional view thereof. Fig. 7 is a perspecview on the line 8-8 of Fig. 6.
Similar reference characters-indicate cor-v respondingparts throughout the several views in the drawings.
Referring to the drawings in detail, A designatesa portion of the support for an article of furniture, for example, the leg thereof, in which is fitted the caster hereinafter fully described.
The caster comprises a glide knob 10 formed in its tread face With a socket 11 in which is fitted a tread body 12 preferably vmade from leather, although the same may be made from any other flexibleI or resilient inturned circular yflange 17 provided with diametrically opposed notches 18, the shank or stem 13 beingv of greater length than the sleeve 14 and formed at itsffree end with dialnetrically opposed nibs 0r lugs 19 which are of a size corresponding to the notches 18 so as to pass therethrough for detachably .locking the shank or stem 13 in the sleeve 14, and in this manner the caster is fastened in the holder. Integral with the upper end of the sleeve 14 is a split resilient bonnet Itive view of the holder. F ig.` 8 is a ySectional 20 forming a plurality of spaced dovvn-i adapted for insertion in the socket C With' inthe support A so that the arms 21 will frictionally engage the Wall of the socket C for the firm fastening oi the holder in the support, the ring B being designed to abut the support A to limit the insertion of the holder therein and prevent its Working in- Wardlysunderthe weight of the article of furniture, I.
ln Figs., 6 to 8 of the drawings there is shown a modified form of caster which comprises a substantially seinispherical shaped glide cup 23 in which is iitted a tread piece 24, the same being formed preferably from leather, yet it may be made from any other suitable flexible or resilient material or composition of materials and is heldfiiast in the cup 23 in lany suitable manner. Rising centrally from the cup is a stem or shank which. is detachably engaged vfor rotation` in a holder hereinafter fully described.
The holder comprises a sleeve 26 for re-v ceiving the stem or shank 25 and is formed with an annular flange 2'?" at one end to engage an annular shoulder 28 formed on the stem' or shank 25 concentrically about the same, the opposite end of the sleeve 26 being formed with an inturned circular-flange 29 provided with diametrically opposed notches 30? through which pass diametrically opposed nibs or lugs 3l formed on the free end of the stein or shank 25 to engage the flange 29, and inl this manner the stem .or
shank 25 yis detachably fastened in. the sleeve 26. l.integral with or secured to the sleeve 26 at its uppermost end is a plurality of diametrically opposed resilient limbs or arms 82, the same being disposed in downftvardly divergent relation to the sleeve 26 and are formed with free hook ends 33 which are adapted 'to :be driven into the support of the article of furniture when the holder is inserted'in the socket therein, and in this manner the said holder is irrnly fastened in the support so as to prevent it from dropping out should the article of furniture be lifted.
Inthe use voli the caster it lWill be clearly apparent that the flooring -or foundation, Whether it be polished or roughened, Will article' of furnitureis moved from 'one point -not become scratched or marred when' the f to another thereover. rlfhe resiliency.. of the n arms or' limbs vof the holders hereinbefore described enable the proper tting of the same within the socket in the support for the article of furniture and also frictionally hold it fast therein. lflhen the article of furniture is moved the caster glides over the ooring or foundation as the stem or shank of the caster freely rotates within the holder when the article of furniture is being 'moved It will be apparent that the stem or shank by reason of the variance yof the length thereof with regard to the sleeve of the holdercan' automatically adjust itself longitudinally in the latter when encountering anyY unevenness in the floor or foundation.
From the foregoing itis thought that the construction and manner ofuse of the device will be clearly understood, and there- Y fore a more extended explanation has been omitted.
The combination with a caster shank, of a holder comprising a tubiform member for receiving the shank and having a contracted inner end to forma bearing shoulder for the shank at one point thereof, an out-turned annular liange formed at the outer end of the said member and forming a bear-lng for the shank at another 'pointJ thereof, a resilient bonnet integral with the member and forming a plurality of spaced outwardly divergent resilient limbs for irictionally securing the holder in an article of furniture, and means at the free end of the limbs to engage with the Flange on the member and also With the article oi furniture for reinforcing the a-nge and also for limiting the inward movement of the holder in the said furniture.. i
ln testimony whereof l affix my signature in presence ,of two witnesses.
