TEXTILE SPOOL OR BOBBIN.

Application filed March 24,. 1921. Serial No. 454,979.

To all wlwm it may concern:

- Be it known that I, HARRY D. CLINTON, a citizen of the United States, residing at Whitney Point, in the county of Broome and State of New York, have invented cer-' tain new and useful Improvements in Textile Spools or Bobbins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

his invention relates to textile spools or bobbins, and the primary object of the invention is to provide simple, eflicient and inexpensive means for securely fastening a hard fiber or metal head or heads to a wooden body so that the head will not be loosened as a result of constant daily use, as in the case of bobbins as heretofore ordinarily constructed.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as a part of this specification, and then pointed out in the claims at the end of the description.

In said drawings,

Figure 1 is a sectional view illustrating the several parts of a spool or assembling;

Fig. 2 is a longitudinal sectional view of the same illustrating said parts assembled and secured together;

Fig. 3 is an end view of the spool; and Fig. 4 is a detail view of the split ring used to secure the body and head together.

Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the letter A denotes a wooden body or center-piece which is preferably cylindrical or tubular in form and provided with reduced end portions or tenons a in each of which is formed an annular groove a adjacent the shoulder a at the base of the tenon. The letter B denotes a head, which may be constructed of hard fiber or metal and is provided with a tapered hole or central opening I) having an annular groove 6 in the outer wall of said hole arranged opposite the groove a when the parts are assembled as hereinafter described. The letter C denotes a wooden plug or bushing, which is preferably constructed of dog-wood and has a tapered head portion 0 to adapt it to expand the tenon a Specification of Letters Patent.

- thus uniting said bobbin embodymg my invention arranged in position for Patented Oct. 25, 1921.

'when driven into the end of the tubular body as shown in Fig. 2 of the drawings. The letter D denotes a split ring, which is preferably constructed of spring steel wire and is adapted to more firmly secure the head upon the tenon by being seated partly in the groove of the head and partly in the groove of the tenon when the tenon is expanded. J

, The several parts are assembled by placing the split ring over the end of the tenon, springing it into the groove a, and insertmg the tenon in the hole through the head from that side which has the smallest diameter, then inserting the tapered bushing through said hole, after dipping it in glue, and driving it firmly into the tubular body, thus expanding the outer end of the tenon and forcing the split ring into the groove 6 of the head, so that the tenon will closely fit the tapered hole in the head and force the wire rin'ginto the groove in the head Where 1t will be firmly seated partly in the groove in the tenon and partly in the groove in the head, while the glue on the bushing secures the latter firmly to the wooden body,

parts and immovably attaching the head center. When the glue is firmly set, the projecting parts of the bushing and tenon are sawed off flush with the outer side of the head and the spool otherwise machined to size. I

Having thus described my invention, whatI claim as new and desire to secure by Letters Patent is:

to the wooden body or l. A spool or bobbin comprising a tubular wooden body having reduced end portions or tenons each formed with an annular lgroove near the base of the tenon, a head aving a tapered hole therethrough and an annular groove therein opposite the groove in the tenon when the two parts are secured together, a spring wire fitting partly in the groove of the tenon and partly in the groove of the head, and a wooden plug or bushing driven into the end of said tubular body and,

having a tapered head portion, whereby said tenon is ex anded and said par-ts firmly secured toget er. V

2. A spool or bobbin having a cylindrical body formed with reduced end portions or tenons having annulargrooves therein, a head having a tapered hole therethrough adapted to receive said tenon and having an annular groove therein pposed to the groove in the tenon when the two parts are secured together, a spring Wire seated in the groove of the tenon and a plug or bushing driven into the end of the cylinder through the smaller end of the tapered opening in the head and having a tapered head portion, whereby the tenon is expanded and said spring wire forced partly into the groove of the head so as to lock and firmly secure, the assembled parts together.

3. The herein described mode of constructing spools or bobbins, which consists in forming a cylindrical wooden body with reduced end portions or tenons having annular exterior grooves, placing resilient split rings in said grooves, inserting said tenons in tapered holes through heads of hard fiber .or metal having annular groovesin the walls surroundin said. holes, and expanding said tenons by riving therein and into the ends of said body wooden plugs having tapered ends and previously dipped in glue thus forcing said rings 1nto the grooves of the heads and immovably securing the parts together. i

4. In a spool or bobbin, a tubular wooden body having a reduced end portion or tenon with an annular exterior groove therein, a resilient split ring seated in said groove, a

head of hard fiber or metal having a tapered hole therethrough in which. said tenon is inserted and having an annular groove in the wall surrounding said hole adapted to register with the groove in said tenon, a wooden plug dipped in glue having a tapered end and driven into the end of said tenon and into the end of said tube, whereby said rin is forced into the grooves of both the head and tenon and the several parts immovably secured together.

In testimony whereof I aifix my signature in the presence of two witnesses.
