Bom'assa, Greene, Maine, assignor, by meme assignments. o himself and Alphonsine our s a as en n s b he en re y Application March 24, 1950, Serial No. 151,739 1 Claim. (Cl. 242 120) s inv t o re t s 8. p ved bobbin Fig. 5 is an enlarged vertical cross-sectional f use especially in the roving process whereview showing the base element secured in 1n it is customary to employ a bobbin having threaded relation toa wooden barrel section a wooden barrel section supported in a position of the bobbin. to be contacted by a metal dog on a spindle gear I have found that one solution to the above in driving relation therewith. indicated problem resides in utilizing a relatively In a roving frame the sliver body builtup. on hard plastic body, such as a vulcanized fiber, to the bobbins is very large. A great deal of dif-. constitute the base section of a bobbin. More ficulty is experienced with the wrecking, or parspecifically, I find that certain forms of vultial break down, of the base section of the bobbin 1Q canized fiber which are characterized by unalso common to hate the base so wattage a provide a reinforced bobbin structure which will vent this wear, including reinforcing rings se- 29 frames and preferably constructed of wood. At
bottom edge of the base, none of which are enin Figs. 2 and The rim ii at 1ts outer petirely satisfactory from a service standpoint riphery is constructed with a cylindrical surface he present invention 1s concerned with the i4 and extending between this cylindrical surproblem indicated and seeks to devise a reinface I4 and the normal peripheral surface l0 for metal reinforcing members. It is also an 0 20 is a reduced neck 22 which is provided with factory operation from a safety standpoint. an annular base element 28 which is formed embodiment of the invention selected for purconverted to a new structure by means of ti eatposes of illustration and shown in the accomment with agents, such as zinc chloride, sulpanying drawings, in which phuric acid, and the like.
Fig. 1 is a view in side elevation illustrating I find that while several types of fiber are not the improved bobbin of the invention, including satisfactory, there is at least one type of vulengagement with the metal dog of a spindle 4.5 the invention. This suitable form of material Fig. 2 is a fragmentary enlarged elevational referred to as bone fiber, characterized by a annular base element removed; of at least 8500 lbs. per square inch measured Fig. 3 is another elevational view of the anin one dimension in thicknesses up to an eighth nular base element with a part of the base eleof an inch; and also characterized by a compresment being shown in cross-section; sive strength of 3000 lbs. per square inch in .all

ment showninFig. 3; and It is intended that a type of vulcaniz firm having properties adhering pretty closely to the above described properties, are to be employed in forming the base portion of the bobbin of the invention.
The base element is designed to fit around each of the specially formed barrel surfaces described above and thus provides for a novel jointed construction. The base element 28 is provided with internal threads 32 and these threads secure the annular base element around the neck portion 22 in such threaded relation that a leverage applied to a strand of yarn which is being wound on the bobbin tends to tighten the threaded engagement of the base element on the bobbin. In addition, an adhesive material 38 is preferably employed to hold the barrel and base in fixed relation to one another. 7
The base element is also constructed with means for forming jointed sections above and below the threaded neck. It includes an annular shoulder 30 which bears against the bottom edge 28 of the neck in a fully threaded position of the base element. A second annular shoulder 34, offset in the base element in a position to abut against the surface 20 of the rim 1!. At its uppermost portions the annular base element 28 includes a lip 48 which is adapted to encircle the cylindrical surface 14 The external periphery of the li 40 is of a generally convex shape and is so chosen that it meets with the concave surface 18 and the two surfaces cooperate to form a reversely curved shoulder of relatively smooth contour for proper handling of yarn wound thereagainst.
The combined threaded and jointed construction of the annular base element and barrel extremity provides a very rugged bobbin construction which it is found, is quite capable of undergoing the shock and wear attendant upon operation in a roving frame. The construction described is well suited to resisting the wear resulting from contact with a metal dog M driven by a spindle gear 42 and engaged in slots 48 in the bottom of the annular base element 28. It will be observed that two distinct bearing surfaces offset from one another are provided in a position to resist impact forces directed axially of the bobbin and base element construction. With this double bearing construction is combined the intermediate threaded relationship for resisting separation of the two members from when subjected to rotative movement, the adhe sive material serving to aid in securing the two parts together.
It W ill 5 With the arrangement 25 shoulder 30 a third radially extending also be observed that with the upper 55 shoulder bearing and rim construction there is achieved a smooth reversely curved thread handling surface composed partly by the wooden barrel and partly by the annular base element. described it has been found that no metal crimping or reinforcing is necessary and that splitting or splintering of the wooden barrel sections is completely eliminated and an exceptionally long bobbin life may be realized.
Having thus described my invention, what I desire to claim as new is:
An improved shock resistant bobbin construcprocess and similar textile operations, said bobbin construction including a cylindrical barrel section of wood and an annular reinforced vulcanized fiber base secured at the lower end of the barrel section and having a downwardly facing slotted portion at its bottom face adapted to be located in driving relationship with the metal dog of a spindle gear, said barrel section being formed with a reduced lower end portion presenting a bottom radially extending shoulder, a second radially extending having its face parallel to the face of the first shoulder located above and in spaced relation to the bottom radially extending shoulder both vertically and laterally, a threaded portion occurring between the upper and lower shoulders,
shoulder spaced vertically and laterally of the second shoulder, said annular reinforcing base being constructed with complementary threads and radially extending shoulder portions, the radially extending shoulder portions of the annular base in a fully threaded position solidly bearing against corresponding shoulder portions of the barrel section at points above and below the threads to provide a shock resistant barrel joint, and all abutting pairs of shoulders being spaced inwardly from the outer wall of the annular base and below the top thereof.
