ALBERT H. CARROLL, OF BALTIMORE, MARYLAND.

BOBBIN.

SPECIFICATION forming` part of Letters Patent No. 245,446, dated August 9, 1881.

Application filed February 24, 1881.

To all whom it may concern Be it known that I, ALBERCL` H. CARROLL, of Baltimore city, State of Maryland, have invented a new and Improved Bobbin; and I do hereby declare that the following is a full, clear, and exact description of the same, refence being had to the accompanying drawings, forming part of this speeitication, in which- Figure l is a side view of a shuttle with a io portion broken away, showing also a portion of the bobbin broken away and in section. Fig. 2 is an end View ofthe bobbin, and Figs. 5 and 4 side views of a inodication of' the same. l

My invention relates to an improvement in that class of iilling-bobbins for the shuttles of looms in which the head or cone is provided at its end with a transverse slot to receive the lug of the winding-spiinlle when the bobbin is zo being filled, and in which a notch or cutis made in the sides oi this head or cone to receive the spring` of the shuttle, which holds the bobbin in place in said shuttle.

My invention consists in two pieces of metal inserted in the butt ofthe cone end in parallel position on opposite sides ot' the center, and whose edges are made to conform to the regular notches in the sides and end of the bobbin, as hereinafter described, whereby these parts 3o are enabled to better withstand the wea-ring strain of the whirling-spindle and shuttlespring.

In the drawings, A represents the barrel or hollow stein ofthe bobbin, having at one end a cone, B. The usual mode of constructing this bobbin is to make it with a transverse slot7 (No model.)

(t, in its cone end, which forms a seat for the lug of the winding-spindle, and with notches or cuts b b on each side of its cone end, which receive the spring of the shuttle., the relation of these notches to the spring,` ofthe shuttle being shown in Fig. l. To enable the faces or walls of these notches to better resist the wear ofthe lug ofthe winding-spindle or the spring of the shuttle, I arrange upon opposite sides of the center ot' the butt-end of the cone inserted parallel pieces d el, which are made of wire, bent to coliform to the contour of the notches, so as to form a bearingin the walls ot' notch a, and also in the walls of notches b I). Instead of bending the pieces d cl to conform to the faces of the notches, l may, as a modification, saw parallel slits in the butt-end ofthe bobbin and stamp ont from plate metal small plates fj', whose edges shall conform to the seats or notches in the cone, and then set these plates in the slits in the said cone, as shown in Figs. 3 and 4.

Having thus described my invention, what I claim as new, is`- A bobbin having its cone end provided with inserted meta-l pieces arranged parallel to each other on opposite sides ot' the center, which pieces serve the double purpose of a seat for the lng of the winding-spindle and a seat or bearing for the shuttle-spring, substantially as described.

ALBERT H. CARROLL.
