IMPROVEMENT IN SPOOLSUOR BOBBINS.

Nwe-

To all whom it may concern Be it known that I, ALEXANDER GARMICHEL, of Westerly, in the county of Washington and State of Rhode Island, have invented certain new and useful Improvements in the Construction of Spools and Bobbins; and I do hereby declare that the following is a full and exact description thereof.

My invention is intended to give increased strength and durability to the articles with the same weight,

or 'about the saine, as when entirely of wood, and with but a slight increase in theA cost. It is of especial advantage in avoiding the roughness experienced with the ordinary wood spools and bobbins, when they are partially worx1.out,and which frequently results in catchiugffineryarns or ratings. and causing them to break.

I cover the peripheries and inner faces of the rims orilanges with a casing of thin metal, or analogous material, which wears smoothly.

I will proceedito describe what I'consiiler the best means ot' carrying out my invention.

The accompanying drawings forni a part of this specication.

Ifigure 1 is a side view, partly in section, ofthe entire spool.

Figure 2 is a'section of the woodportion only of head. This is an ordinary form and construction adapted to be covered, but to which the cover has no yet been applied.

Figure 3 is a view of the metal vwithl a portion broken away.v It shows the material of the cover when first cut out, and while in a plane condition.

Figure 4 shows the same after one operation of the dies, not represented.

Figure 5 shows the same after the wood portion and the covering material has been applied together, but before being finally compressed together so as to fold the covering upon the wood.

Figure 6 shows the same after the covering is partly folded down upon the wood. 5

By turning now again to iig. l, it will appear that the covering is there vclosely foldeddown upon the wood. i

Similar letters of reference indicate like parts in all the figures.

A is 4the body or barrel, and A B1 B2 are two thicknesses of wood glued with their grain crossing eachother, which together form the head. lhey are secured vto -the barrel preferably by both screw-threads and glue. The outer edge of the flange or head is rounded. The two heads may be alike, or one may be thicker, or in any wayvaried from the other, as may be desired. What are termed bobbins are usually analogous in structure, but with onlyone head. The heads may be of various kinds of wood, but I esteem it important that they are made primarily of wood, in two thicknesses glued'to- Y getlier, the grain of the wood in one thickness crossing the grain of the wood in the other thickness, as

above described.

So far as is yet described the structure is identical with those long known, and in common use.

Toenoase the inner faces and periphery of a head,

I take a sheet of tinned iron, cut in a circular form,

and haring a hole in the center a little less in diameter than the exterior of the barrel or body A of the spool.A I strike this dat disk of iron between convois and concave dies, so as to turn up the periphery. I lit into this the wood head of the bobbin, and then, by means of one or more other dies, bend the' turnedup edge firmly over, and-compress it into the wood of the head, in the position represented by d 1n iig. 1.

This cased head is now ready to be ijrinly united to the barrel'A by the ordinary, or any suitable means, andfuldls admirably the functions, notonly of strengthening the union of the'two thicknesses B1 B together,

aiding to defend the entire head against splitting or other breakage in case of falling upon the floor, or other'violence, but also of insuring a smooth inner face to rub against the yarn in the act of being drawn on".

In the use of spools or bobbiiis for some purposes, the yarn is drawn directly over the end. -In suoli case it is highly important, not only that the inner face of the heads, vbut also the entire periphery of the head shall be smoothly cased'. My casings, by extending not only over the entire inner faces, but also oyer the entire periphery, fulfil this end Very perfectly in addition to the others before enumerated.

It will be observed that my casing, by extendinginward to and alittle within the barrel,fc'0vers` the whole inner surface of the head, and avoids the risk of thread or rovings being caught on the inner edge, which, in-use, is liable to get rough and to proJect. Also, that by the embracing fof both thicknesses ct my crossed wood at the periphery of the head, they are aided in holding firmly and inseparably together.

And also, that being struck up and compressed on the wood, as explained, the damage diie to the heat of casting on a metal casing is avoided.

I claim* A spool or bobbin, haring a'head of wood in two thicknesses with the grain crossed, and a hard casing oi' metal extending over the entire inner `surface and orer the periphery, so as to coat and strengthen the surfaces and bind the wood together, when the casing is formed and applied without injury to the wood,'and in the'manner and for tl1e` purposes herein set forth.

'In testimony whereof I have hereunto set my name in presence of two subscribing witnesses.

ALEXANDER OARMIOHEL.
