ANDREW TAYLOR, OF GOLTDVILLE, SOUTH CAROLINA, ASSIGNOR TO CLINTON CAM COMPANY, OF CLINTON, SOUTH CAROLINA, A CORPORATION OF SOUTH CAROLINfl.

BOBBIN-SKEWER.

Application filed February 2, 1916.

T 0 all whom it may concern:

Be it known that I, Anni-112w TAYLOR, a citizen of the United States of America, and a resident of Goldville, county of Laurens, State of South Carolina, have invented certain new and useful Improvements in Bob bin-Skewers, of which the following is a full and clear specification.

This invention relates to that class of skewers employed for holding bobbins in roving machines. In this type of skewer, as is well known, the skewers arc journaled vertically in a creel, the upper end of the skewer being held loosely in a top bar and the lower pointed end of the skewer being provided with a top or point, bearing in a cup or socket formed in or mounted on the bearing rail of the creel. The bobbin is slipped down over the skewer and rests upon an annular shoulder positioned at the lower end of the skewer. An objection to this common form of skewer as now made is that when the skewer carrying the bobbin is accidentally dropped on the floor, as frequently happens in handling the bobbin, the bearing point is broken and the wooden shaft of the skewer is sometimes shattered.

It is the object of my invention to provide the lower or bearing end of the skewer with a device which will prevent such injury to the skewer when a loaded skewer is accidentally dropped.

In the drawings Figure 1 is a side elevation of a skewer provided with my improved point;

Fig. 2 is a vertical sectional view of the lower end of the skewer; and

Fig. 8 is a plan view of the skewer point detached.

Referring to the drawings annexed, a is the usual wooden stafi of the skewer. At its lower end, this stall is reduced in diameter to form a tenon b and a downwardly-facing, beveled, annular shoulder 0. A metal socket d incloses the ten-on b snugly and is fastened thereto by a screw e passed through a hole in Specification of Letters Patent.

the socket and screwed transversely into the tenon. Formed integral with the lower end of this socket is a disk 7' which is sufliciently large in diameter to form a support for the bobbin spool. Depending centrally from the disk f is an integral bearing point 9, and formed integral with the socket d is a plurality of radial vertical ribs 7b which bear against the inner face of the bobbin spool and serve to center the same 011 the disk lly thus fastening the staff in a metal socket carrying an integral supporting disk and an integral bearing point, it will be seen that likelihood of injury when a loaded skewer is dropped point-downwardly on the floor is practically eliminated. The socket and its integral parts are formed of metal so that fracture thereof is practically out of the question. The clasping of the lower end of the staff in a metal socket prevents splitting and shattering of the staff, as is obvious, and the use of radial ribs as a means of centering the bobbin is advantageous as compared with a continuous annular shoulder, in that the danger of foreign substances lodging between the bobbin spool and the centering device is reduced to a minimum. By employing a metal socket for the staff, I am enabled to employ a fastening screw to connect the socket with the staff instead of an adhesive, which latter is unreliable.

Having thus described my invention, what I claim is:

In a skewer, the combination of a wooden staff, a metal socket fitted on the lower end thereof and provided with a hole, a screw passed through said hole into the part of the staff inclosed in the socket, said socket being provided with an integral supporting flange and a depending bearing point and also with vertical radial ribs for centering the bobbin spool.

In testimony whereof I hereunto affix my signature.

ANDREW TAYLOR.
