BOBBlN-CATCH FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 373,261, dated November 15, 1887.

Application filed July 8, 1887.

To all whom it may concern.-

Beitknown that I, ISAAC L. ALLEN,of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Bobbin Catches for Spinning- Machinesof which thefollowing-isa full, clear, and exact description.

In machines for spinning yarn or rope the bobbins on which the yarn is wound are ordinarily arranged axially within the fliers of the machine,and have both an independent rotary motion and longitudinal travel on and along the spindle'of the fliers. These two independent motions are communicated to the bobbins by means of a revolving head or button-carrier attached to a longitudinally-sliding and axially-revolving sleeve, and fitted with a button which engages with a catch upon one head of the bobbin.

Heretofore the bobbin-catches in use have usually consisted of a simple plate nailed upon the outer face of the one head of the bobbin over a recess or cut-out portion in said head, at a suitable distance from the axial center of the bobbin, said plate having a square or oblong opening in it, which faces the recess in the bobbin-head, but is narrower than it, whereby the plate forms opposite straight overlapping flanges for engagement with the head of the button which drives the bobbin. Said button has two separate functions-that is to say, by its rotation with the button head or carrier it rotates the bobbin by lateral pressure upon one of the overlapping flanges of the bobbin catch or plate, and moves the bobbin longitudinally in the one direction by the pull of the button-head on the overlapping flanges of the plate or catch as the button-carrier is slid in a given direction,said revolving and sliding button-carrier, as it is slid in the opposite direction, pressing on the outside surface of the plate or head of the bobbin to reverse the traverse of the latter. These bobbincatches are a great source of annoyance and expense in a mill. They are constantly coming off the bobbin by the pulling or working of the button upon them, and have to'be renailed to their places with the nails in the same holes as before, thus making their retention very insecure. Furthermore, said catches and the buttons, always presenting Serial No. 243,765. (No model.)

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents alongitudinal section of a yarn-winding bobbin hung to rotate and slide upon the dead or center spindle of the flier, and having my improved catch applied, also showing the rotating and sliding buttoncarrier with attached button which drives the bobbin. Fig. 2 .is a transverse section upon the line or a: in Fig. l; and Fig. 3 is a sectional View of the bobbin-catch having a smooth instead of a screw-threaded exterior, as in Fig. 1.

A is the bobbin, fitted, as usual, to rotate and longitudinally slide upon the spindle B of the flier and within the flier, which latter is not shown here,as it forms no part oftheinvention;

O is the button-carrier, and bits sleeve,with attached pulley c, fitted to rotate upon and slide along, as usual, the spindle B, outside of the one head 01 of the bobbin, for the purpose of rotating and reciprocating the bobbin longitudinally, the ordinary or any suitable means being used to rotate and reciprocate the button-carrier through its pulley c.

D is the button or driver secured to the carrier O at any suitable distance from its center.

E is the bobbin-catch applied to the head d of the bobbin, and arranged to engage with the button D. This bobbin-catch isin the form of a circular thilnble, and may either be plain, as shown in Fig. 3, on its exterior, and be driven to its place within a circular hole made through the head of the bobbin, and maybe cylindrical or tapering on its exterior, or have a screw-thread on its exterior and be screwed into the head of the bobbin, as shown in Fig. 1; or it may be otherwise fixedly secured in the head of the bobbin. Said thimble-like bobbincatch is constructed with an interior flange, s,

on its outer end, for the head of the button D to engage with to draw or slide the bobbin in the one direction, while the shank of the button, pressing upon the inner peripheral surface of the flange 8, serves to rotate the bobbin.

This construction of the bobbin-catch will very greatly reduce cutting and wear of the button and its catch, and the catch or thimble may be turned in its seat from time to time to change the wearing-surfaces, and so further prolong the durability of the catch, while its firm and secure attachment Within the head of the bobbin does away with all liability of its working loose or falling out.

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

1. The within-described bobbin-catch for yarn-spinning machines, the same consisting of acircular thimblc having an iuteriorflange on its outer end, substantially as specified.

2. The combination,with the bobbin A, having a circular aperture in one of its heads outside of the axial center of the bobbin, of the circular thimble-likebuttoncatoh E, fitted within said aperture and provided with an interior flange, 3, on its outer end, essentially as described.

3. The combination of the button-carrier G and its attached button D, the spindle B, the bobbin A, and the circular thimble-like bobbin-catch E, having an interior flange, s,upon its outer end, substantially as and for the purposes herein set forth.

ISAAC L. ALLEN.
