ELLA S. HALL AND ALEXANDER N. KAZNAKOFIE, OF NEW YORK, N. Y.
THREAD-GUIDE GBIPPER.
Application filed June 6,
To all whom it may concern:
Be it known that we, ELLA S. HALL and AL -morn N. Knamurorr, citizens, respectively, of the United States and Russia, and residents of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and improved Thread-Guide Gripper, of which the following is a full, clear. and exact description.
I'his invention relates to a thread guide and support, and has for an object the provision of a simple, efficient, durable and economically manufactured device which can be attached to any type of thread spool whereby thread may be easily held to prevent unravelling of the thread from the spool.
The invention is illustrated in the drawings, of which Figure 1 is a perspective view of the spool with our device attached thereto;
Figure 2 is a side elevation partly in section of a spool with the device attached; and
Figure 3 is a perspective view of the attachment itself.
The preferred form of our invention, as shown in the drawings, is applicable to any type of thread spool, such as 1, on which thread 2 is wound. These spools are generally provided with an interior bore 3.
We provide a cap at, made of any suitable sheet metal, in the form of a flat circular disk which has around its edges a downwardly projecting, crimped-over flange portion 5 (see Fig. 2). In order to hold this cap or disk against one end of the spool 1, we provide a pair of spring fingers, such as 6, which are formed of one continuous piece of sheet metal and are adapted to extend downward into the bore 8 of the spool and grip the interior wall thereof. The upper ends of the spring fingers are bent in the form of a head portion 7 at right angles to the finger 6, and the ends of this head portion 7 are adapted to be gripped by the turned-over flange portion 5 of the disk 4. In forming the device, the cap 4 is formed without having the flanges 5 turned over. The head 7 of the spring fingers 6 is then placed within the cap, whereupon the flange is crimped and turned over, and in being turned over the head portion 7 is gripped therebetween.
The fact that the cap 4; and the resilient spool-engaging member are made of a con- 1921. Serial No. 475,258.
tinuous integral piece of sheet metal and can be formed by machinery and assembled in the same manner makes this device which is composed of two simple parts, a very economical one to manufacture and which at the same time is strong and eflicient I fingers 6 are bent and curved at a plurality of points, such as 9 and 10, to engage the walls of the bore 3 throughout the length of the fingers to give a more uniform gripping action. The ends 11 of the spring fingers 6, as shown in Figure 2 particularly, it will be observed, converge toward each other so that they touch only at their tips. The curvature at a plurality of points of the fingers, together with the tapered relation of their ends, insures at all times for the fingers the desired amount of resiliency whereby a sure and uniform gripping action will take place between the spring fingers and the walls of the spools. The tapered eifect of the end 11 will also facilitate the entry of the device in the bore 3.
What we claim is:
1. An attachment for thread-carrying spools, which comprises a sheet metal cap adapted to be disposed adjacent one end face of the spool and having its edges curved over to form a flange portion, and a resilient single-piece spring extending from the cap into engagement with the bore of the spool, a portion of said spring being engaged. by the edge of the cap.
2. An attachment for thread-carrying spools having an inner bore, which corn: prises a cap formed of a single piece of sheet metal having its outer edges curved over, a spring finger extending from said cap and adapted to engage the walls of the bore, and a head portion connected to said spring finger, the ends of the head portion gripped between the crimped-over edges of the cap, and a plurality of bore-engaging portions or projections on said finger.
3. An attaeinnenttor thread-carrying spools having a bore, which comprises a sheet metal cap formed of a single piece of material having its edges curved ov r, and a pair of curved spring fingers extending from said cap into the bore to engage the Walls thereot, said spring fingers having heads thereon adapted to lie along the inner face of the cap, the ends of said heads being gripped between the curved-over edges of the cap.
*1. An attachment iOl' spools to hold the ends of the threads, which comprises a sheet metal cap adapted to be disposel adja(:. ii
tl'iread-carrying i an end of the soool, said spool having bore therein, and a pair of resilient spring lingers adapted to extend into the here to engage the in is thereot, said fingers each having a plurality of flared curved portions thronghont its length adapted to bear against and contact with the Walls of the bore, the ends of the fingers tapering or converging toward each other at a slight angle.
5. An attachment for thread-carrying spools which comprises a sheet metal cap having its edges bent over in a smooth curve and adapted to bear against the end of the spool, a pair of spring fingers extending into the bore of the spool, said fingers having a plurality of curved engaging portions throughout their length, the outer ends of the fingers converging toward each other whereby the ready entry of the device into the spool is effected, the end of the spool being engaged by the turned-over edges of the cap.
