STEAM BOBBIE.

Application filed April- 5, 192?. Serial No. 181,1d5.

I are usually made for this purpose comprise a wooden core and metal flanges at the opposite ends. A plurality of steel or iron rodsare driven. through the length of the bobbin and overturned upon the ends of the flanges to hold the flanges in place. In addition, a plurality of holes are driven through the Wooden core'the entire length of the bobbin and a plurality of longitudinal series of holes are bored radially into the bobbin to inter-' sect the longitudinal'holes. The bearing for the bobbin passes through the center .bore of the bobbin core and steam isconducted through the outwardly disposed longitudinal bores, this steam being discharged radially outward through the holes in the bobbin on to the yarn. This style of bobbin'is very shortv lived. After-being in use a short time they become distorted due to the warping'of the woodas a result of its severe treatment bythe steam. Even, when this distortion is relatively slight and when the bobbin is relatively new the distortion may be noted by the irregularity in the winding of the thread,

, and the only remedy possible is to'discard the distorted bobbin and substitutea new bobbin therefor. This causes considerable expense and'loss of time, and furthermore is likely to cause an improper winding of the thread upon the'bobbin even when the bobbin is relatively new.

The general object of this invention is to do away with these objectionable features and to provide a steam bobbin which will not became distorted due to warping, but which will maintain its shape and which will therefore, last indefinitely. L I

A further object is to provide a'bobbin having a wooden core, metal flanges at the ends of the core, and metal sleeves extending entirely through the bobbin and through the flanges from which sleeves the steam passes so that the steam will not effector distort constructed i accordance with my invention.

Figure 2 is a longitudinal section of the same.

Figure 3 is an end elevation of the device.

accom- Figure 4 is a transverse section on the line 4 4ofFigure2.

Referring to these drawings, it will be seen that the core of my improved bobbin designated 10 is made of wood as usual... On. each end of this pore is dispose a circular disk or flange 11 as it is called, which is of any suitable material as for instance; steel or bronze. Between the ends of the core 10 and the metallic flanges or disks, there is provided a thin gasket of rubber 12 or other suitable packing material. The center of the core3is bored as at 13 to admit the spindle or 7 other axis upon which the bobbin rotates. The core is longitudinally bored at three or more points as at 14 for the admission of the steam, and bronze tubes or sleeves 15 are driven through theseDbores, these tubes being of sufiicient length so that they may be riveted or overturned into the countersunk holes in the flanges. Coacting with each of the bores 14 are a plurality of radially directed passages 16, these passages being drilled through the bronze tubes so as to provide an outlet for steam upon the face of the core. These bobbins are of the'same size and character as the ordinary steam bobbins and are interchangeable therewith. This bobbin has a relatively long life and in this construction, the t ee bronze tubes not only act to line the pa sages 15, but also act to take the place of the wire rods ordinarily used, the tubes being overturned into the. countersunk margins, and holes of the flanges being as strong 'as the rods Utilizing the three tubes as steam ducts'and eliminating the use of unlined bores, will prolong the life of the bobbin 'and prevent distortion. In use, these bobbins run on spindlesin a spinning frame. The flanges rest on friction pulleys which" rotate the bobbins to wind the thread. While T have illustrated the core as being made of wood, lldo not wish to be limited to this as other fibrous materials might be used. Neither do ll wish tov be limited ,to the use of this bobbin as a steam bobbin as it is appli cable "for use inv many 'difierent circumstances. L

Tn use, the bobbin after being wound is placed with a number of others in a conta ner and the container is placed in a steam The passages and apertures in the bobbin permit thesteam to circulate through the. bobbin and thoroughly steamithe thread. It can also be used for dyeing thread. The

gaskets between the ends of the wooden core and the flanges 11 are used to prevent the thread from catching in any small aperture or cracks that might be left after fittingthe flanges, and these gaskets assure that no aperture exists after the bobbin is finished. It is not ne'ccessary to bush the radial passages 16 because these are short and cut across the grain of the woodi. The wood will, of course, absorb some moisture during the steaming process but it cannot absorb it from these short radial passages to any such extent that it can ever the longitudinal passages. The absorption of the steam as a consequent distortion of the Wood core in the old style bobbin not only distqrts the Wood;

but also distorts the wire rods .which are used to hold the flanges in place. :In my improved bobbin, the tubular rods as they may be called which bush the longitudinal passages and which are overturned upon the ends of the flanges are much stiffer than the wire rods and will not bend or yield, nor otherwise become. distorted.

1. A bobbin of the character-described including a non-metallic core, metallic flanges disposed oh the ends of the core, passages extending longitudinally through the core and flanges, interior perforated sleeves disposed in said passages and extending through the. flanges, and radial passages opening upon the face of the core and communicating with the interior of said sleeves through said perforations.

2. A bobbin of the character described ineluding a non-metalliccore, metallic flanges on the ends of the core, passages extending longitudinally through the core and flanges,

and opening upon the face of the core and 1 into said sleeves.

, 3. A bobbin of the character described 1nclu ding a non-metallic core, metallic flanges greater in diameter than the diameter of the core, gaskets disposed between the ends of' the core and the inner faces of the flanges, the core being formed With longitudinally extending passages and tubular SlGGVGS'CllS- posed in' sai passages and extending through the core, the gaskets, and the flanges overturned upon the ends of the flanges, the core being formed with a plurality of radial passages extending through-the face of the core and into each of said .tubular sleeves.

4. A bobbin of the character described including a non-metallic core having a central longitudinally extending spindle passage, flanges on the ends of the core larger in diameter than the. core and having a central spindle aperture, the core being formed with longitudinally extending passages and the flanges having a lining, countersunk openings and tubular sleeves extending through the passages and through the openings of the flanges and overturned under said countersunk openings, the core being formed with a plurality of radial passages for each of the longitudinalpassages and extending from the face of the core into said metallic sleeves.
