Diss, a A in the supporting plate and the parts connected thereto.
The invention provides an improved and simple construction which affords means for properl'y supporting the furniture and permitting or facilitating its being slid about when the caster wheel, jaws and pintle are removed or withdrawn, as well as serving to cooperate with the jaws and pintle to sup? port the furniture thereupon when the jaws and pintle are in place.
l'n its most complete and preferred form, the invention provides an improved structure having a leg supporting plate, av pint-le holdingjsocket secured to the plate, spring means for frictionally acting on the interior of a tubular leg to hold these parts thereto, and a leg mount member for surrounding the leg and secured to the leg supporting plate so as to substantially cover and extend beneath the edges o f the plate, the leg supporting plate having a plurality of downwardly curved or bulged portions constituting slide members, upon which the furniture may easil slide when the caster wheel, jaws and pint e are not in place.
Certain other features of the invention will be understood from the following descripti'on.
The preferred embodiment of my invention is exemplified and shown in the attached drawings, in which,
Figure 1 is a erspective view showing the caster in positionl in relation with a furniture leg of tubular construction, Fig. 2 is a side view of Fig. 1, partly in vertical section. Fig. 3 is a bottom view with caster wheel and jaws removed. Fig. 4 is a sectional plan view of one of the details.
ln the drawings A represents the caster wheel, B the jaws and C the pintle attached thereto in any appropriate manner. The pintie is retained and directed to its proper position within the leg and guided thereto j by apint1e socket composed of an inner spring member D and an outer tube E. The pmtle C has at its upper extremity a head or projection F, immediately below which` it is contracted to a smaller circumference.
Spring member D resiliently actin beneath the headF retains the pintle C within its socket, and the pintle is further maintained in such osition by the action of the outer tube E irectly bearing against the pintle head F. The pintle socket tube E is made to 'directly bear on and against the pintle by reason of the tube being at its u 'per extremity contracted to a smaller circumference.
The furniture leg G shown in square form is directly supported by the le supporting plateH and rests thereon. '.l ie leg supporting plate H is rigidly attached to the outer tube E by any desired means, here shown in the drawings by crimping 'the outer tube E above and below where it meets and joins the leg supporting plate H.
The pintle socket is retained within the leg by means o f a resilient or spring member J which is perforated at K, and through which erforation the pintle C and the outer tube extend, and above which perforation the tube is upset or enlarged.
The spring member J extends transversely around the intle and the outer tube E, and its free en s extend downward and act frictionally outward against the interior of the leg G.
The leg supporting plate H shown as square is at its corners provided with ears K which underlie portions of the leg mount L and support same. The leg mount L, which is also shown square, is inturned so as to cover and hide thc edges of the leg supporting plate, except where the ears K underlie the leg mount. It will be evident that these ears K are almost invisible when the leg mount is viewed from above. The inturned ange portions M of the leg mount and the ears K coperate to hold the leg mount very securely and rigidly to the leg support-in plate. The leg supporting plate is prefere ly lished upward by means of a circular shoulder or corragation as seen' at I in Fig. 2 and indicated by the two circular lines at .N in Fig. 3. This serves to stiii'en the plate, as will be well understood, and also, by coming against the inner edge of the foot of the leg, it may assist the leg flange portions M of mount and the spring member J 'in centering i the parts relatively to the leg. -The leg supporting plate is also provided with a vplurality of slide members O formed bylbulging the plate downward a suliicient distance to insure the bulges or slide members pro'- 4 jecting to a lower level than the inturned j the leg mount, in order to allow their being used` as slide supports when the wheel, jaws and pintle are withdrawn. They are made very smooth, so` as to reduce friction in sliding, -and they should extend down sufficiently to protect' the flange portions M from contact with the floor or surface on which they rest. With the rectangular form of plate, they are preferably located at the four corners, as shown.
At P, Fig. 2, is shown a common form of ball bearings for the caster jaws, surrounding the pintle beneath the plate H.
From the foregoing description, the operation of the entire structure will be apparent.- 4Then the pintle is withdrawn, the furniture maybe slid about on the slide members O, and this is particularl useful in the factory and salesroom 'be ore the furniture is sold and pintles inserted.A
Without meaning to limit myself to the particular details of the-form of the invena leg supporty carried,y thereby for acting frictionally on the interior of a tubular leg, a leg supporting plate securedto the said socket, a leg mount member adapted to surround vthe leg and having portions inturned .beneath the leg supporting plate, and said plate Vhaving projections which underlie and support the eg mount member;
3. The combination of a caster socket adapted to receive a pintle, spring means carried thereby for acting-frictionally on the lnterior of a ytubular leg, a legsupporting plate secured to the said socket, aleg mount member adapted to surround the leg and the said plate having' a plurality of slide members bulgingvdown-` ward near its periphery. 1
carried by said plate,
4. The combination of av leg supporting plate provided with a plurality of .downwardly projecting rounded slide members and a central perforation adapted to receive the caster pintle, of resilient means forsecuring the plate to the vleg and means for det-achably holding the caster pintle when in place.
5. A caster structure having avleg supporting plate which is dished or recessed upward and provided with a central perforationv for receiving the caster pintle and a plurality of downwardly bulging slide members adapted to slide over a fioor.
6. A caster structure having an angulary leg supporting plate provided .with ears and a leg mount having inturned portions whichI extend beneath the said plate and portions resting upon the said ears in intervals between the inturned portions.V
In testimony whereof I have signed this specification in the presence of two subscribing witnesses June 17, 1911.
