UNIT BOBBIN CONSTRUCTION Filed May 10, 1949 2 Sheets-Sheet 2 {up INlfENJiOR.
A TTOENEYS Patented Feb. 28, 1950 UNI T BOBBIN CONSTRUCTION am e. Crooks, shaman, N. Y., assignor to Lestershire Spool and Manufacturing Company, Johnson City, N. Y., a corporation of New ork Application May, ill, 19,- S'erial No. 92,335 4' Chins. (or 242-424) This invention relates to bobbins or the like. and the principal object thereof is to provide a umt barrel assembly in which the parts are truly concentric for high-speed operations, the bobbin having removable or interchangeable interiltting heads so that in event a head should breali same can be quickly and readily removed byyremoving the screws which secure the head toithe bobbin body and a new preformed concentric head inserted by replacing the screws without destroying the truly concentric relation of the parts,
thus providing an inexpensive, novel and; eflicient bobbin particularly adapted for high-speed purposes, the same being particularly adapted for winder twister bobbins. 'j
I will explain the invention with reference to V the accompanying drawings, which illustrate several practical embodiments thereof, to enable others familiar with the art to adopt and use the same; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.
In said drawings: Figure 1 is a side elevation, partly in'section, through one modification of my novel bobbin.
Fig. 2 is a similar view, showing a modification. Fig. 3 is a plan view of one face of a head. Fig. 4 is an enlarged detail section on theline fl-t. Fig. 5.
Fig. 5 is an end view of the bobbin shown in Fig. 1.
Fig. 6 is a vertical section through the head shown in Fig. 3. 1
As shown, my novel bobbin comprises a barrel 2, a center tube 3, heads i, a base washer d, and a top washer 5; the head being secu'i gd to the base and top washers 4 and 5 by screws I, and the bobbin may include bushings 6 at one or both ends of the bobbin, also a iiyer ferrule 8 at the end adjacent top washer 5.
The barrel 2 and heads I are preferably made of aluminum, magnesium, fibre, Bakelite, stainless steel, or other suitable material; while the spindle bushings 6 may be made of any suitable material, such as Bakelite or nylon, the same being inserted to provide journals in either or both ends of the bobbin, where desired, to fit special spindles.
In making the bobbin, a tube of the above barrel material is first roll ground so as to render same truly cylindrical on its outer surface, the barrel being mounted for this purpose in the centering chucks of a suitable grinding machine. The ends of the barrel 2 are then counterbored as at 2:4, utilizing the exterior of the barrel as as 2 a true dimension to render the counterbored portions 2a truly concentric withthe exterior oi the barrel.
. Base washer 4 is then seated in the counterbore 2aof the barrel 2, the washer having been provided in its outer face with a recess 4a havin an annular shoulder- 4b, and with tapped bores 4d for the screws I. In preparing the washer 4, same is turned, bored; recessed as at 4a, and shouldered as at D, all in one machine setting so that all parts thereof, including the inner diameter and outer diameter, are truly concentric. The holes 4d for the screws 1 are then accurately drilled and tapped.
The top washer 5 is then similarly seated in the counterbore 2a at the other end of the barrel 2, the washer 5 being provided with a recess 5a in its outer face and an annular shoulder 5b, the top washer 5 being turned, bored, recessed as at 5a and shouldered as at 5b in one machine set ting so that all parts thereof including the inner diameter and outer diameter, are truly concentric. The holes 5d for the screws 1 are then accurately drilled and tapped.
The exterior of the center tube 3 is then roll ground, using the inside diameter of the bore as a center, and the parts 2, 3, 4 and 5 are then assembled as shown in Figs. 1 and 2, the ends of the center tube 3 swaged as at 3a and 3b over the shoulders 4b and 5b of the washers 4 and 5, preferably by a rolling operation, thus providing a unit barrel assembly.
The heads l are bored as at la, and counterbored as at lb to fit the outside diameter of the barrel 2, the heads being turned truly concentric to fit concentrically on the end of the barrel assembly 2. The heads are then drilled as at Id for the screws 1 and their peripheries turned as at lc, using the internal diameter of the heads as a center. The heads being then assembled on the unit barrel assembly by means of the screws i In event a head i should break, the head may be readily and easily removed by removing the related screws 7 and inserting in its place a preformed head which is secured by reinsertion of the screws 71, such replacement in no manner destroying the truly concentric relationship of the parts, and thus not destroying the usefulness of the bobbin for high speed operations.
If desired, bushings B. of any suitable material, such as Bakelite or nylon, may be inserted in either or both ends of the bobbin to fit special spindles; but in the majority of instances the bushings may be omitted. Also a flyer ferrule 8 may be retained in the bore l a of thehead i adjacent the top washer 5, the same being retained in the bore by means of a shoulder la: formed at the outer end of the bore in of said washer. Where not desired, the ferrule 8 may be omitted.
bores f the washers with its ends rolled over the outer faces of the washers, thereby locking the parts together.
2. In a bobbin or the like, a unit assembly consisting of a barrel having annular recesses in the ends of the bore thereof, washers seated within the annular recesses and having central bores with concentric enlargements at their outer ends, annular shoulders within the enlargements, and a center tube extending through the bores of the washers with its ends rolled over the annular shoulders, thereby locking the parts together.
3. A bobbin or the like, comprising a unit assembly consisting of a barrel having annular recesses in the ends of the bore thereof, washers seated within the annular recesses and having central bores, and a center tube extending through the bores of the washers with its ends rolled over the outer faces of the washers, thereby locking the parts together; and replaceable heads removably secured to the outer faces of the washers and having bores registering with that of the center tube and having counterbores receiving the ends of the barrel.
4. A bobbin or the like, comprising a unit assembly consisting. of a barrel having annular recesses in the ends of the bore thereof, washers seated within the annular recesses and having central bores with concentric enlargements at their outer ends, annular shoulders within the enlargements, and a center tube extending through the bores of the washers with its ends rolled over the annular shoulders, thereby looking the parts together; and replaceable heads removably secured by screws to the outer faces of the washers and having bores registering with that of the center tube and having counterbores receiving the ends of the barrel.
