Description
Patented Sept. 4, 1934 BOBBIN George H. Magrath, Whitinsville, Mass. Application January 17, 1933, Serial No. 652,151
6 Claims.
The principal object of the invention is to provide a bobbin having a clutching device for hold' ing the bobbin firmly in fixed position during the winding and/or spinning operation, which device may also provide a reinforcement for the bobbin and be readily assembled therewith, and which is of a simple construction, economical to manufacture, and efiicient and reliable in operation.
Further objects relate to my improved bobbin and will be apparent from a consideration of the following description and accompanying drawing which shows different embodiments of the invention chosen for the purpose of illustration.
1n the drawing:
Fig. 1 is a longitudinal sectional view of a bobbin constructed in accordance with the present invention and shown in operative position on a spindle of the type generally used in spinning operations;
Fig. 2 is in section, of a bobbin struction; 1 r
Fig. 3 is an elevation of the spindle-engaging bushing shown in Fig. 2; and
Fig. 4 is a top plan view thereof.
In the embodiments herein shown for the purpose of illustration the bobbin comprises an elongate cylindrical member having the usual blade portion 1 terminating at one end in an enlarged butt portion 2 and having an axial bore 3 which extends the entire length of the bobbin. In accordance with the present invention the butt portion is provided with an enlarged axial bore .4 which receives a spindle-clutching bushing or insert constructed and arranged yieldingly to engage the periphery of a spindle to hold the bobbin in place. Preferably, one end of the bushing is provided with a flange or rim member shaped to embrace the end of the butt portion of the loobin to provide a reinforcement therefor and to hold the body portion of the bushing firmly in position within the bore.
In the embodiment shown in Fig. 1, the bobbin comprises a cylindrical bushing having a body portion which is received within the bore 4, and an annular flange 6 integral with the body portion, the flange terminating in an upwardly dithe construction or a fragmentary side elevation, partly embodying a modified con- .rected rim '7 which has a pressed or driven fit U. S. Patent No. 1,952,764,
about the end of the butt 2. The flange and rim member not only provide a reinforcement to the end of the bobbin but also firmly securethe body portion of the bushing in, position within the bore 4. The body portion is provided with a plurality of spaced longitudinallyextendingslits 8 defining radially flexible fingers or segments 9 which may be bent inwardly, as shown inj Fig. 1, to insure a firm ments are spaced from the inner periphery ,or walls of the bobbin so as to permit an unrestrained flexing movement thereof. f The bushing may be of any suitable material, such as sheet metal, capable of providing spindle engaging segments which possess more or less resiliency and sufficient stiffness yieldingly .to oppose outward flexing movement. *If desired, resilient means such, for example, as an annular spring member 10 circumpose'd about the segments 9 may be employed yieldingly to restrain the flexing movement of the segments and in crease their gripping action.
When the bobbin is placed shown'in Fig. 1, the segments?) spindle S, as I are flexed outwardly and yieldingly'engage the neck 13 of the spindle, andthe butt portion seats upon the outer end of the whirl 11 which is provided with a fiat shoulder portion, here shown as an annular collar 12 having a pressed'flt about grip on the spindle. The seg- Ii over the blade of 'a the whirl and conical neck 13. If desired the spin- 585 dle may be made with the fiat shoulder portion integral with the whirl, thus dispensing with the use of the collar 12. The diameter of the open-. ing in the flange 6 preferably corresponds exactly with the diameter of thejneck 13 at i'tsbase so 901).
the whirl and range oitravel of the yarn-guiding devices, thus overcoming the necessity of making readjustments of such devices before winding each bobbin as is usually required with the prior constructions wherein the bobbin is forced over the spindle so that the butt portion wedges about the neck and does not assume any definite or fixed position relative to the whirl or yarn-guiding devices. Moreover, with the present construction there is no danger of spindle.
stood that for those herein I i made without departing from the spirit and scope therewith an annular wardly yieldingly to engage 60- the bobbin losing its grip on the spindle during the winding operation, or vibrating out of proper position, and consequently the winding operation may be carried out more accurately and at a greater speed than heretofore possible.
The embodiment shown in Figs. 2, 3 and 4, is quite similar to that shown in Fig. 1 except that the body portion of the bushing is provided with slots 17 intermediate its ends and the segments 19 defined thereby are bent inwardly at their central portions, as shown in Fig. '3, to provide suflicient resiliency firmly to grip the neck of the previously described embodiment. It will, be noted that in each of these embodiments, the bushing not only provides a reinforcement which strengthens and protects the butt portion of the bobbin, but furthermore holds the spindle clutching segments in spaced concentric relation within the bore of the bobbin. 1 1
While I have shown and described different embodiments of the invention, it is to be underin shape, proportion and arrangement of parts, as well as the substitution of equivalent elements shown and described, may be oi -the inventio claims.
