BOBBlN- CARRlER.

SPECIFICATION forming part of Letters Patent No. 618,542, dated January 31, 1893i.

Application filed July 7,1898. Serial No. 685,818. (N0 model-l To all whom it may concern.-

Be it known that I, HENRY J ANSSEN, a citizen of the United States of America, and a resident of Reading, county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Bobbin-Carriers, of which the following is a specification.

This invention relates to a special form of racer or bobbin-carrier designed more particularly for use with flat threads, the main object being to avoid twisting or edgewise bending of the latter,-while providing in a simple and inexpensive mechanism for the usual automatic feeding of the thread under uniform tension.

Figure 1 is a front elevation of a carrier embodying my invention. Fig. 2 is a side elevation of the same.

A represents an ordinary carrier-base designed to ride in the curved ways of a braiding-machine. B and B are two parallel standards rising from said base. Between these standards is mounted horiz'ontallya bobbin 0 upon a pin D, which is preferably held in place by means of a spring E, adapted to engage a circular groove (1, formed near the projecting end of the pin, thus permitting the bobbin to be easily placed in position or removed.

Directly beneath the'bobbin Oand between the standards is the tension-weight G, which is provided, as shown, with a thread-pulley g, the center of which is located at the intersection of the vertical planes on m and y y, which respectively cut the bobbin midway of its length and on the center line. The thread h from the bobbin passes under the pulley g and is carried upward through the threadguide 1), formed at the junction of the standards, said guides being located, as shown, on the center plane w a; and sufficiently forward of the bobbin-center to allow the thread It to pass freely to it from the pulley 9, no matter to what position the latter may be moved between the standards B B, which serve to guide it. It will be seen that the tensionweight is thus carried centrally below the bobbin by the thread it and that the latter is at all times carried from the bobbin around the pulley g, through the guide 1), without any objectionable bending or twisting.

The automatic feed mechanism is similarin operation to that commonly employed. The head a of the bobbin forms a ratchet which is engaged by a pawl F, pivoted at f to one of the standards. This pawl is operated by a projection g on the tension-weight, which depresses it against the tension of a spring f, to release the bobbin when the weight rises to the position indicated by dotted lines.

The spread of the upper portion of the standards B B is greater than the lower portion, the object of this being not only to permit the use of a somewhat larger bobbin, but also to provide room for the easy introduction and removal of the tension-weight, which latter may be readilyraised out of engagement with the guide=standards when the bobbin is removed.

It is obvious that the specific construction described and shown may be modified in matters of detail Without departing from my in- Vention.

What I claim is A bobbin-carrier comprising a base, parallel standards thereon having an increased spread at the top, a horizontal bobbin mounted between said spread portions of the standard, and provided with a ratchet-wheel, a pawl pivoted to one of said standards, and a tensionweight overlapping the lower portion of said standards and adapted to operate said pawl; said bobbin and pawl being movable to permit the raising of the weight to said spread portion of the standards whereby it may be removed from the latter substantially as set forth.

Signed by me, at Reading, Pennsylvania,

this 1st day of July, 1898.

HENRY JANSSEN.
