sroon Application tiled August 18, 1923. Serial- Ho. 657,256

My invention relates to spools in which a tubular member is provided at its opposite ends with relatively short sleeve-like portions located interiorly thereof, which portions constitute bearings for supporting the spool upon a spindle or the like, and in which also the opposite sheet-like end portions thereof are separately constructed and secured to the opposite ends of the tubular member in planes extending substantially at right angles to the axis of the spool.

It is desirable that these end sheets be secured to the opposite ends of the tubular structure in such?l manner that they may not be accidentally disconnected and also in such manner that theyy Will not work `or become It is, therefore, the principal object of the invention to provide novel means whereby such end' sheets. may be permanently and rigidly secured to the opposite ends of the tu ular structure.

It is a further object of the invention to provide novel means whereby the attachment of the said end sheets to the oppositeends of the tube structure of the spool shall be stronger than heretofore has been the case inso farasI am aware.

To these and other ends my invention comso prehends a. construction and ar ement of parts as hereinafter fully describe particuarly pointed out in the claims and as illustrated in the dra in which I have shown `a convenient form o embodiment thereof.

In the drawing: I 1 is a view partly in side elevation and partl in central longitudinal section of a spoo constructed in accordance with my invention;

Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. 1; Fig. 3 is atransverse sectional view taken onthe line 3 3 of Fig. 1;

lar to that shown in Fig. 3 'but showing a slight modification of the structure.; and

Y 5 is a, rspective view of one of the fastemng devices employed for securing the end lates to theopposite ends of a tubular oo member of the slool structure.

Referring to e drawing: 1 designates a tubular member constituting a spool structure upon which string, cord, wire and the like are a'da ted to bewound. Situated the interior of the tubular member 1 at its oppote ends are short part.- of asleeve-like portions 2 which yare secured in place in any suitable manner. In order that -the said sleeve-like portions 2 may be secured in place so as topositively prevent the loosening and the removal thereof, I have not only cemented the exterior surfaces of the said portions 2 to the interior surface of the tubular member 1, vas indicated at 3, but I have also inserted tacks or nails 4 through the tubular member 1, which tacks or nails extend into the members 2. The outer ends of the sleeve-like members 2 should be ilush with the outer ends of the tubular member 1, as is clearly shown in Fig. 1 of the drawing.

The sleeve-like members 2 constitute bear- -ings for the spool in case the same is placed upon a spindle or the xlike.

The tubular member l is provided at its" opposite ends with flat end sheets 7 of diskshape and in order to secure these sheets firmly, securely and permanently in place I have provided wire staples -10 the opposite legs of which extend inwardly intermediate the sleeves 2 and the adjacent portions of the tubular member 1.

In the construction as shown I have provided or employed two of these staples, but it will be understood that an additional number may be employed if desired. The intermediate cross portions of these staples are located upon the outer sides of the sheets or plates 7, as indicated. It will be noted that the inner. ends of the sleeves 2 are beveled, asxindicated at 11. The inner ends of the opposite legs ofthe staples 10 are bent over the inner edges of the said sleeves and terminate against the beveled surfaces 11, as is clearly shown in the drawing. These bent over ends 17 extend inwardly in substantial- 1y radial direction with respect to the tube and terminate outwardly or outside of the interior surface of the sleeves 2. Fig. 1 is a transverse sectional view simi- In the construction as shown in Fig. 1 the opposite legs of the staples are shown as oc- ;iulp'ing grooves or notches 15 in the outer aces bers 2. l,

In` 4 a modification using a reverse arrangement isshown. The tubular member 1 is rovided with longitudinal grooves 16 upon lts inner surface. The legs of the and the inner ends of the opposite. legs of these sta les 10 are bent over the mner beveled of the sleeves 2'.

of the sleeve-like bearing memlstaples 10 occupy positions in these grooves also desirable that the inner ends of the drical member,

legs of the staple shall be bent as indicated at 17 so as to interlock with the inner ends of the sleeves 2.

n, It will be seen that by the employment of staples in which the cross portion thereof which connects the opposite side legs are situated exteriorly of and in contact with the end sheets of the spool structure, and in which the inner ends of the opposite legs are -bent inwardly and over the inner ends of the bearing sleeves and are interlocked therewith, an extremely strong, neat and durable structure is produced.

It will be understood that in the 'construction of spools embodying my invention I am not limited to the particular means showh for securing the sleeve-like parts 2 in position in the interiors of the opposite ends of the tubular member 1, but the securing ot the said sleeves within the opposite end portions of the tubular member may be eiiected in any desired or preferred manner which will insure against accidental disconnection of the same from thelsaid tubular member.

Spools embodying my invention may be constructed of any suitable material, but I prefer to construct the same of paste-board. In case paste-board is employedr the outer end sheets 7 should be subjected to a-suitable treatment, such as subjecting the same toa bath of sulphur, Montan wax, or the like, which increases the density and also renders the same more rigid and resistant to external forces which may` be applied thereto. It

` will be understood,*however, that any suitable material may be employed in the manufacture of spools embodying the invention.

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

1. A spool, comprising a cylindrical portion upon which string, cord, wire and the like are adapted to be wound, end sheets secured to the `opposite ends of the said cylinalld staples extending through said end sheets and interlocked with the opposite end portions of the said cylindrical member, thesaid staples being. arranged in planes parallel to each other.

2. A spool, comprising a tubular member,- sleeve-like members situated in the opposite -m'y invention, I have hereunto signed end portions of the said tubular member, end sheets situated at the opposite ends of said tubular member, and staples arranged, in parallel relation to each other, the oppo-` site legs of each of which lextend through: said end sheets and interlock with the said` portions, end sheets at the opposite ends of the said tubular member, and staples the said staples being arranged in planes parallel to each other, the opposite legs of each of which extend through said end sheets and intermediate the said sleeves and the adja` cent portions of the opposite ends of the Said tubular member, the inner ends of the opposite legs of said staple being bent around and interlocked'with the inner ends of the said sleeve-like members.

4. A spool, comprising a`tubula`r member, sleeve-like members located in the interior of the opposite end portions of said tubular member, the inner ends of said sleeves being beveledou'twardly, means for securing the said sleeves in position within the said tubular member, end sheets located at -the opposite ends of said tubular member, and staples having their opposite legs extending through said sheets and inwardly of the said tubular member intermediate the opposite end portions thereof and the said sleeve-like members, the inner ends of the said legs being extended inwardly and terminating upon the outwardly beveled inner end portions of said sleeves.

5. A spool, comprising a tubular member, relatively short tubular members located in the opposite ends of said tubular member, said short tubular members being provided with exterior longitudinally extending grooves, means for securing the said relatively short tubular members in position,y

sheets of disk-shape secured in contact with the outer ends of the said tubular members,

Aand staples in parallel relation to each other and having their opposite legs extended through the said sheets, the said legs extend;V

the inner ends of the said" iplatively short' tubularl members.

In testimony that I claim the foregoing as my name this. 1st day of August, A. D. 1923.

JAMES MORRIS BROWN.
