SPOOL.

SPECIFICATION forming part of Letters Patent No. 358,705, dated March 1, 1887.

Serial No. 169,170. (No model.)

To aZZ whom it may concern:

Be it known that I, LEONARD 0. SMITH, a citizen of the United States, residing in the city and county of Philadelphia, State of Penn sylvania, have invented a new and useful Improvement in Spools, which improvement is iully set forth in the following specification and accompanying drawings, in which- Figure 1 represents a side elevation of 21.

IO spool embodying my invention. Fig. 2 represents end views of the parts thereof. Fig. 3 represents a longitudinal section thereof.

' Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a compound spool formed of two or more flanged spools which are connected as one, as hereinafter set forth, and readily separated as desired, the operation and advantages being hereinafter fully set forth.

Referring to the drawings, A represents a compound spool formed of two or more spools of wood. On the end of one of the spools is a circular or annular projection, 13, of less diameter than the body of the spool, and in the end of the other spool is a socket, G, of greater diameter than the bore or central opening of the said part, thereby forming a shoulder on the end thereof. The said socket is adapted 3c to receive said projection B and hug the same, and the depth of the socket being the same as the length of the said projections the ends of the flanges are brought into contact, whereby the two spools are connected as one.

It will be readily seen that, owing to the form of the projection and the nature of the material, the spools are firmly held together for the purpose required, but may be easily and quickly separated when so desired.

In place of a cylindrical projection, as shown in the drawings, a conical or spherical one may be employed without departing from the principle of myinvention. The spools may readily be formed with the projection by means of a lathe, and the socket is easily bored, thus form- 5 ing an inexpensive as well as desirable article.

The advantages of my invention are as follows: In dress-making and family sewing it is desirable to have an exact match in the silk and twist to be used. By dyeing both sizes of silk at the same time and securing the twistspool to the one containing silk the silk and twist are kept together until ready for use. Under the method heretofore practiced the silk and twist are separated and placed in different boxes, the sizes being separated and possibly sent to different places, so that the merchant or dealer may receive silk and twist dyed at different times and not exactly alike in tint, all of which is obviated by my invention.

The spools may be separated, so that each spool may be used by itself, either for handsewing, buttonhole making, maehinesewing, 00., or other purposes. It is also evident that the spools, when united as one, are serviceable 6 5 for holding together thread of different materials or colors, preserving each by itself.

I am aware that it is not new to form a. spool with spaces thereon separated by flanges, and such I do not broadly claim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A compound spool formed of wood, and of two parts, both of which have end flanges and central openings, one of the parts having an end projection of smaller diameter than the body of the said part, and the other part hav ing a socket larger in diameter than the cerr tral opening and adapted to receive the said projection of the other part,wl1ieh fits therein, the said projection and flanges being integral with said parts, all combined substantially as and for the purpose set forth.

LEONARD O. SMITH.
