( Cl. 1 This invention relates to ‘cone holders for use on knitting or other textile machines. In knitting or other textile machines, where the yarn or thread is wound on cones, the latter will vary in length, degree of taper and diameter, with the result that the machines have to be adapted to the particular cone. It is, therefore, an object of this invention to provide a cone bears at its lower end against the supporting por tion of the creel frame with which the bolt I I is engaged. The upper end of the spring It bears against the lower side of the sliding or ?oating washer I4. Preferably the spring I6 is a rela tively weak spring so that when a cone I ‘I, as shown in Figure 1, is disposed in telescoping posi tion over the washers I2 and I4, the lower or slid ing washer I4 will move downwardly and auto10 matically adapt itself to the taper of the cone various kinds and types of cones. I‘! so that the lower washer I4 will engage the Another object of this invention is to provide inside surface of the cone I1 at a point below the a cone holder of this type which can be mounted upper washer I2. The upper washer I2 is secured on the present structure of creel frames. to the upper end of the bolt I I by means of a nut A further object of this invention is to provide a cone holder which is of simple construction and 15 I8 which is threaded on a reduced stud I9 carried by the upper end of the bolt I I. will ?rmly hold a cone in operative position so As shown in Figure 2, the \cone holder can easily that the cone can be easily and quickly applied and quickly adapt itself to different types of cones or removed from the holder. or cones having different tapers. The cone 20 To the foregoing objects, and others which may hereinafter more fully appear, the invention con 20 shown in Figure 2, has a more shallow taper than the cone I‘I shown in Figure 1, and in adapting sists of the novel construction, combination and itself to the cone 2n the ?oating or sliding washer arrangement of parts, as will be more speci?cally I4 will be moved downwardly a greater distance referred to and illustrated in the accompanying until this washer I4 ?rmly contacts the inside drawings, but it is to be understood that changes, variations, and modi?cations may be resorted to 25 surface of the cone 20 and coacts with the down wardly ?ared ?ngers of the washer I2 in provid which fall within the scope of the invention as ing spaced supporting surfaces for the cone. The claimed. washer I4 is substantially larger in diameter than In the drawing, the diameter of the washer I2 including the ?n Figure 1 is a detailed side elevation of a cone holder constructed according to an embodiment 30 gers I3 and is of such diameter with respect to the washer l2 that substantially all types of cones of this invention, for mounting on the creel frame conventionally used with textile warping opera of a textile ‘warping machine, showing a cone in tions will be engaged by and supported in opera vertical section mounted thereon, v tive position by this holder. Figure 2 is a view similar to Figure 1, showing In mounting the cone IT on the holder, the a different form of cone mounted on this holder, 35 holder which will automatically adapt itself to Figure 3 is a sectional view taken on the line 3—3 of Figure 2, Figure 4 is a plan view of the sliding or ?oat ing washer used with this device. Referring to the drawing, the numeral Ill des ignates generally a portion of a creel frame for a knitting machine which has secured thereto a bolt II. The bolt I I, which may be either ver tically or horizontally disposed, has mounted on cone is extended over the washer I2 and the ?n gers I3 until the ?ngers I3 contact the inside sur face of the cone. At this time the lower washer I4 is moved downwardly against the tension of 40 spring I6. The cone I1 is then given a partial clockwise turn so that the ?ngers It will bite into the cone in a threading action and thereby lock the cone on the device. The cone is removed by counterclockwise turning thereof, followed by the upper end thereof a washer I2 which is 45 endwise movement. I do not mean to con?ne myself to the exact formed with downwardly ?ared inclined cone en gaging ?ngers I3, which produce a threading details of construction herein disclosed, but claim all variations falling within the purview of the means so that the cone will be locked by such ?n appended claim. gers upon partial clockwise turning of the cone.
