BOBBIN-THREAD-SL P?LY HOLDER AND GUIDE.

Application filed May 1,

To all whom it may concern:

Be it known that we, lhlAX GI BERT, a citizen of the United States, residing at Bronx, county of Bronx, and State of New York,

5 THOIvi-AS GUIDE, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, and Sono- MON .Kir'rz, a citizen of ltussia, but having taken out his first papers in the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Bobbin- Thread-S-upply Holder and Guide,of which the following is a specification.

This invention is a thread holder so constituted as to render it highly efficient in supporting a large roll of thread in a position convenient to the bobbin of a machine and embodying means for guiding said thread during the winding thereof on a bobbin;

large manufacturing establishments, it is the practice to buy thread in relatively large rolls or tubes which thread is taken from the rolls or tubes and wound on the bobbin as Occasion may require. The thread is delivered to the factories in the form of large rolls or tubes which when not in use are set on shelves or on the tables of machines until such time as the threading of a bobbin is necessary whereupon the rolls or tubes manually manipulated into position to thread the bobbin and after the threading is completed the rolls or tubes are once more placed on sh yes or on a table of a machine. The handling of these rolls or tubes loosely, as is the universal practice, causes the thread to become soiled and in most larg factories one or more of these rolls or tubes of thread may he found on the iloer at time. Long before the roll or tube completely used, the thread becomes loosened thereon and slips from the end of the roll or tube and becomes tangled in such condition that it is unfit for use and it is not uncommon for wl'iicle rolls or tubes cit-such thread to be inadvertently gathered up with sweepings and ,tEhnown This practice is very wasteful in thread and no means is provided in the large manufacturing establishments for either conserving the thread by eliminating waste or maintaining the thread wound prior to its winding on the bobbin,

\Vith the foregoing considerations in 1924. Serial No. 710,238.

mind, the object of the present invention is to provide a neat, compact and efficient 13eceptacle or hold-er, one of which is adapted to be associated with each machine and in a position convenient to the bobbin, though so conveniently positioned that it will not become an obstruction to the operator of the machine. A roll or tube of thread is adapted to be housed within the casing which'is provided with outlet reaching into pro-X- iinity with the bobbin o f the machine and the thread is threaded through this outlet and only ashortend thereof normally protrudes therefrom. When it is desired to thread a bobbin, this short end is carried to the bobbin, secured theretoand the winding convenient position for winding the next bobbin. 7

At all times, however, the roll or tube of the thread is housed within the casingand maintained in clean condi on and in such form as to preclude tangiingor wasting of the thread.

The casing is so formed as to enable a roll or tube of thread to be readily introduced thereintowhen the roll or tube previously therein has been exhausted.

In the pneferred practical form of the vention, the casing of cylindrical ,form and is mounted on the under side of the table of a machine by means of a suitable bracket. Extending upwardly from the casing is an outlet channel or passage which while being pulled from the roll and wound upon the bobbin.

The device is simple in construction, economical to manufacture and fulfills a long felt want in ,manufactories where large quantities-of thread are used. The thread is kept cleanandwasting is precluded.

Features of the invention, other than those specified, will be apparent from the hereinaiter detailed description and claims, when read in conjunction with the accompanying drawings.

The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a perspective View 01" the device of the present invention showing the casing in opened condition, and,

Figure 2 is an end elevation of the device showing the casing in closed position and mounted on a table of a machine.

Referring to the drawings, 1 designates a cylindrical casing parted diametrically in a vertical plane to divide the-section into two parts 2 3, which are hinged together as shown at a. @ne end or" the casing is closed by a circular disc 5, one half of which is r' ly secured to the section 2 and the remaining half of which is loose with respect to the section 3, The opposite end of the casing maybe closed by a fiat plate or disc adapted to bear against the end of the sections 2 and 3 but unattached to either.

The casing is adapted to be mounted on the table 6 of the machine by means of a of any suitable form. This bracket 4 bracket is secured to the section 2 of the casing and is adapted to be permanently fixed to the table of the machine by means of screws or bolts 8.

Extending coaxially of the casing and rigidly fixed in the end plate 5 thereof is a bolt or axle 9. This bolt is somewhat longer than the casing and is adapted to extend through the perforation in the opposite end plate of the casing and for an appreciable distance beyond this end plate. The bolt 9 provides a support for roll or tube of thread 10, the thread being wound upon a suitable carrier or bushing 11 adapted to lit over the bolt 9 as shown in Figure 1. The desired tension may be ap olied to the roll by means of a helical. spring 12 coiled about the end of the bolt 9 exteriorly of the nd plate of the casing and this spring is placed under the desired tension by means of an adjustable collar 13 adapted to be locked on the bolt in any desired position by means of a set screw 1 1. In lieu of the collar 13 however the end of the bolt may be threaded and a nut screwed upon the bolt for the purpose of placing the spring 12 under the desired tension.

Extending upwardly from the top of the 1g is an outlet duct 15 which at its base, where it joins the casing, is substantially equal in width to the length of the casing, but from this point the duct tapers upwardly to substantially circular section and bent preferably on the arc of a circle in the direction of the bobbin 16 of the associated machine. This bobbin is shown in dotted lines at 16. The outlet duct is divided centrally into two sections 17 and 18, the former of which is rigid with the section 2 of the casing while the latter of which is rigid with the section 3 of the casing. Moreover, the outlet duct terminates in an outlet or guide tube 19, the free end of which extends into proximity with the bobbin 16. This guide tube is mounted rigidly on the section 15 of the outlet duct and once the casing is closed and the sections oi the outlet duct in assembled relation, the free end of the outlet duct section 18 will abut the rear end of the guide tube 19, so as to form a closed passage from the interior of the casing to the outlet end of the guide duct 19.

When it is desired to position aroll of thread in the casing, the collar 13 and spring 12 are removed and a roll thereupon passed over the bolt 9. During this operation, the section 3 of the casing and the section 18 of the outlet duct are swung back on the pivot 1 to permit this operation to be conveniently carried out. roll 10 is in position on the bolt 9, the free end or" the thread, designated in the drawings by the reference character 10, is led upwardly through the open side of the section 17 and threaded through the guide tube 19, after which the casing is closed. is to say, the section 3'is swung upwardly on the pivot 4 until the section 18 of the out let duct comes into face abutting relation with the section 17 of the duct.

During this operation, the section 18 will 7 be gripped by spring fingers 20 mounted on the section 17 and these spring fingers Will tightly maintainthe duct and casing in closed position. The under plate,not shown, is next applied to the openend of the casing and thereafter the spring 12 is placed over the end of the bolt and the collar 13 brought into position and locked in placeby the set screw let to place the spring under the desired tension. The casing is made of such length that the under plate will bear against the end of the roll and so that the tension of the spring may cause the under plate to vary the friction between the roll and said plate and thus place the thread as it is drawn through the guide tube 19 under the desired tension.

The parts are preferably made of sheet metal so that the end tube is more or less resilient and properly permits of its operation.

At the conclusion of the operations described, a short length of thread is left hanging from the outer end or" the guide tube 19, so that when a bobbin requires threading, this end may be lead to the bobbin, secured thereto and the threading op- After the thread That 7 eration carried out. When this threading operation is concluded, the thread is cut adjacent the bobbin and a free end is left hanging from the end of the tube 19 ready for subsequent winding operation.

it will be apparent from the foregoing detailed description of the invention that it is of marked utility for the purpose stated and that it not only keeps the thread perfectly clean but also provides a housing and holder for the thread so that it is protected against unraveling or tangling with the resuit that there is no loss or waste.

The drawings show the invention in itsv preferred practical form, but the invention is to be understood as fully commensurate with the appended claims.
