l @ZZ whom t may concern.'
lie it known that I, lVnNznL PornLmi, a subject of the Emperor of Austria, residing at Cincinnati, in the county of Hamilton and State of Ohio` have invented certain new and useful improvements in Spoolltlolders; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
'.ihis invention relates to new and useful improvements in spool holders, and the principal object of the invention is to provide a spool holder for holding spools from which thread is being unwound.
Another object of the invention is to pro vide a device having a bearing mounted thereon which is arranged to space the bottom end of a spool upwardly from the base, so as to present a minimum bearing surface for the spool and thereby reduce the friction to a minimum.
A still further object of the invention is to provide a device which may be easily and cheaply constructed having a relatively heavy base which serves to hold the same against accidental movement.
llith these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure l is a perspective view of a spool holder constructed in accordance with this invention, and showing the spool removed; and
F ig. 2 is a vertical sectional view through the spool holder showing a spool in place so as to illustrate the means of reducing the friction on the spool.
Referring to the drawings, l designates the base of the device, comprising a rectangular block having formed in its upper face a socket 2 into which the spindle or stem designated by the numeral 3, is litted. This spindle tapers toward its upper end as clearly illustrated in the drawings and the upper end of the spindle together with the upper edges of the blocks are chamfered or beveled as at l in order to avoid the production of sharp edges on which the clothing of the user is apt to be torn. The standard or stem 3 is held in the socket 2 by the frictional engagement of the wall of the socket with the stem, thereby avoiding vthe necessity of providing any other form of fastening and reducing the cost of production to a minimum.
The bearing element is designated generically by the numeral et and comprises a ring which fits tightly around the base of the stem 3 and flares upwardly and outwardly as clearly shown in Fig. Q. Formed at the upper edge. of the ring 5 is a downwardly and outwardly extending flange 6 and the point where the fiange G joins the ring 5 forms the bearing designated by the numeral 7. The extreme outer' edge of the flange 6 is downturned as at S so as to engage the upper surface of the block l and avoid any possibility of the flange G turning up so as to form a space between the block l and said fiange. The downturned portion S also serres to stiffen the whole and prevent the bearing member a from being distorted.
it will be apparent from the foregoing, that in use, the spool is set on the spindle 3 so that its lower end or base rests on the bearing 7 and it will be seen that when pull is exerted on the thread wound on the spool, the spool. will freely turn and the base will remain stationary owing to the reduction of friction between the spool and base, and the weight of the base.
ll'lhile in the foregoing there has been shown and described the preferred embodi ment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims.
Vhat is claimed is l. A spool holder comprising a relatively heavy base, a spindle secured centrally of the base and extending upwardly therefrom, a ring surrounding the spindle adjacent its lower end and extending upwardly and outwardly therefrom, and a flange on the ring bent downwardly and outwardly so that its free edge engages the upper side of the base, the point of uncture of the flange with the ring forming a reduced annular bearing member', as and for the purpose specified.
2. A spool holder comprising a relatively heavy base, having a socket in its upper face. a tapered spindle fitted in said socket and tapering toward its upper end, said spindle extending upwardly at right angles from the base, a'ring adapted to frictionally engage the spindle adjacent its lower end, said ring extending upwardly and outwardly In testimony whereof I aPX my signature 1n presence of two wltnesses.
