BOBBIN AND THREAD HOLDER FOR SPINDLES OF S'PiNNlNG-MACHINES.

SPEGIFIOATION forming part of Letters Patent No. 621,218, dated March 14, 1899.

Application filed September 21, 1898. Serial No; 691,497. (No model.)

Yb al'ZZ whom it may concern:

Be it known that I, OLIVER O. BURR, a citizen of the United States, residing at North Adams, in the county of Berkshire and State of Massachusetts, have invented new and useful Improvements in Bobbin and Thread Holders for Spindles of Spinning-Machines, of which the following is a specification.

This invention relates to improvements in bobbin and thread holders for spindles of spinning-machines, the object thereof being to provide a simple, cheap, and effective means for holding the bobbin in engagement with the spindle and means for holdingand releasing the thread or yarn, the construction of the device being such as to embody in a single article of manufactureabobbin-holder and a thread holding and releasing device which comprises in the make-up of the structure a bobbin-holder having a plurality of spring-arms carried by the spindle and positioned thereon so as to contact with the periphery of the head of the bobbin to hold and centerthe same on the spindle, the device also including a thread-holder'of the type shown in Letters Patent No. 578,810 issued to me on the 16th day of May, 1897.

In the practical embodiment of my invention I employ a thread-holder which is of less diameter than the head of the bobbin and a bobbin-holder which does not extend materially beyond the bobbin-head, the same comprising resilient arms which engage with the periphery of the bobbin-head without projecting above the same.

In the prior state of the art it has been common to provide the spindle of a spinning machine with a bobbin-holder consisting of oppositely-disposed spring-arms which are carried by the spindle and adapted to be forced apart by a downward pressure of the bobbin, so that the bobbin-head would be engaged by the upwardly-projecting ends of the spring-arms, which held the bobbin on the spindle by frictional contact with the bobbinhead, or with a recess formed in the under side of the head, means also being provided whereby the thread could be held while doffing the bobbin.

The present invention consists in the special construction and combination of the parts as an improvement upon my patent hereinbefore mentioned as well as an improvement upon the type of bobbin and thread holder shown in Patent No. 83,354, dated October 20, 1868, as will be hereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view, partly in section, the section being taken through the bobbin and through the bobbin-holder and thread-catcher. Fig. 2 is a side elevation, the bobbin-holder and thread-catcher being shown in section. Fig. 3 is a perspective view showing the parts separated.

A refers to the spindle to which the bobbin-holder and thread-holder is attached, the bobbin B being of the ordinary type.

a refers to a collar or sleeve, of malleable metal, as brass, copper, or soft iron, the internal diameter of which is approximately the same or slightly less than the diameter of the spindle where it is desired that the parts shall be attached to each other. 7

Z) refers to a disk having at its peripherya downwardly-extending V- shaped flange b,

and between this flange and the central opening in the disk are apertures b Immediately above the disk I) is positioned the bobbinholder 0, which consists of a central portion 0 of approximately the same diameter as the disk 19, the same having outwardly or radially projecting arms c'with upturned ends which are adapted to grasp the head of the bobbin. This bobbin-holder has on a line with the apertures 19 apertures 0 The parts Z) and C are held in rigid engagement with each other and are fixedly attached to the collar'or sleeve (1, and, if desirable, these parts may be integral with each other.

D refers to the movable member of the thread-holder, which is reciprocally mounted on the sleeve or collar a, the same having an aperture d of slightly-larger diameter than collar or sleeve, upwardly-projecting pins d, which are rigidly afflxed to the upper portion of the movable member D, and a beveled upper edge or periphery d which is adapted to engage with the beveled or inner portion of the depending V-shaped flange b of the disk.

The movable member D, with the exception of the pins, may be spun or struck up from a piece of sheet metal and the side flares outward, this member being bell-shaped and of suflicient depth to extendbelow the collar or sleeve (1, so as to form a cover or protector for the helical spring E, which is placed over the collar, so as to engage with the movable member I) and a washer F, which is placed over the lower end of the collar or sleeve. lVhen the parts are assembled upon the collar or sleeve a,the ends of said collar or sleeve are expanded and upset, so as to hold the parts C b and the washer F in rigid engagement with the sleeve a, the spring and bellshaped member D being movable upon the collar or sleeve. The pins (1, carried by the member D, project through the apertures in the parts I) and O and are engaged by the bobbin-head when it is held by the bobbinliolding arms of the part 0.

By the construction shown the parts are all connected and the movable member of the thread-holder covers the spring, so that there is no liability of the yarn being caught between the coils thereof. The reciprocal member D is adapted to enter the fixed member, so that the thread when placed between said members will be securely held, and the parts are so shaped as to provide for the automatic taking up of wear. It will be further noted that the parts are so constructed that they are all held together by the collar or sleeve, and said collar or sleeve is adapted to be placed over the spindle and driven to the desired position thereon, which driving on and expansion of the sleeve will only tend to make more secure the parts which are in fixed engagement with the same. This improvement is susceptible of application to spindles already manufactured, and when applied it not only serves as a bobbin-holder and a thread-catcher, but also centers the bobbin on the spindle.

The bobbin-holder has preferably three 1'a dially-projecting arms with upturned ends to engage the side of the bobbin-head, though a greater number may be used, if desired, and as said arms are attached to a common center it is obvious that they will center the bobbin on the spindle, which is not the case shouldthe holders which engage the bobbinhead be susceptible of independent movement. It will also be noted that the threadholder is positioned below the bobbin and its head.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a bobbin and thread holder for spindles, the combination of a bobbin-holder connected to a spindle so as to externally engage the bobbin, a part of the bobbin-holder coaeting with a thread holding and releasing device, the parts consisting of a fixed member and a movable member, a collar to which they are attached which collar embraces the spindle, and a spring mounted on the collar so as to move one of the members toward the other and means carried by the movable member for separating it from the fixed member when the bobbin is placed on the spindle so as to engage the bobbin-holder.

2. A bobbin-holder and thread-catcher for use with spindles and bobbins, comprising a member having a plurality of outwardly-projecting resilient arms which are adapted to engage with the head of the bobbin, a sleeve which connects the parts and frietionally engages the spindle, a disk fast upon the sleeve and to the bobbin-holder, a movable member spring-actuated in one direction and movable away from the bobbin-holder when the bobbin is placed on the spindle and caused to engage with the retaining-arms of the bobbin-holder, substantially as shown.

3. In a thread-holder for spindles, the combination with a revoluble spindle, a sleeve through which the spindle is passed so as to be held thereon, a disk immovably connected to the sleeve, a member reciprocally mounted on the sleeve, a spring for actuating the movable member toward the fixed member, a bobbin-holder fixedly mounted on the sleeve and means carried by the movable member which project upwardly there from so as to be engaged by the bobbin when it is engaged by the bobbin-holder, substantially as shown.

4. In a thread-holder for spindles, the com bination with the connecting means as a collar or sleeve, a disk having a depending peripheral flange fixedly attached to the collar or sleeve, a bell-shaped member, a spring which encircles the collar or sleeve and engages with the bell-shaped member to move the same toward the fixed member, the bellshaped member having its upper edge beveled, substantially as shown.

5. As an improved article of manufacture a combined bobbin and thread holder, comprising a bobbin-holder having a plurality of radially-projecting arms which are adapted to engage with and center the bobbin on the spindle, a movable member constituting a part of the thread-holder the same being spring-actuated in one direction to clasp the thread, pins extending therefrom through the bobbin-holder so that the movable member of the thread-holder will be moved away from the bobbin-holder when the bobbin is placed on the spindle so that the head thereof will be engaged by the spring-arms of the bobbinholder, and a collar or sleeve which frictionally engages with the spindle and carries the hereinbefore-mentioned parts, substantially as shown.

6. The combination with a collar or sleeve, a disk having apertures therethrough and a beveled periphery attached to one end of the collar or sleeve, a washer carried by the opposite end of the collar or sleeve, a bellshaped member movably mounted on the collar or sleeve, a spring inelosed by the bellshaped member, the spring engaging with the ICC washer and said bell-shaped member, and pins which extend from the bell-shaped member and pass through the apertures in the disk, substantially as shown and for the purpose set forth.

7. In a thread-holder for spindles, the combination with a sleeve which frictionally engages the spindle, a bobbin-holder having three or more resilient arms for engagement with the head of a bobbin when mounted on the spindle, a movable bell-shaped member located below the bobbin-holder, for the purpose set forth, and provided with upwardlyprojecting pins which pass through apertures in the bobbin-holder, and a spring for moving the bell-shaped member toward the bob= bin-holder the spring and bell-shaped member being mounted on the sleeve, substantially as shown. i

8. The combination with a spindle, of a bobbin-holder having apluralityof arms with upturned ends, said bobbin-holder having apertures therethrough, a disk attached to the bobbin-holder, a collar or sleeve in rigid engagement with the bobbin-holder the disk and with a Washer located at the opposite end of the collar or sleeve, a member loosely mounted on the collar and provided with upwardly-proj ectin g pins, and a horizontal portion which engages with the member which is loosely mounted on the collar having a disk, at depending side which overlies the spring which encircles the collar and engages with the washer,the parts being connected together by the collar, substantially as shown and for the purpose set forth.
