` SPOOL.

Appligation filed AprilH 9, 1925, Serial' No. 21,946.' Renewed November 8, 1928.

This invention relates to an improved construction of spool, reel or the like on which wire or other materia-l may be wOund; and

v the object of thisinvention is to provide such a-spool having a tubular body with a head at each end thereof, the inner faces of the heads being recessed to receive the ends of the body portlon to preventV relative rotation between them, independent means being 4also provided for locking or securing the heads to the boy ith 'thesefand other objects in view, the

invention consists of certainnovel features of yconstructioxn-as will be more 4fully described,and-particularly pointed out in the ap ended claims. .u

n the accompanying drawings Figure l is a sectional elevation of. my improved spool showing one form of head which `is attached to the body thereof.

Figure 4 is a perspective view showing the collar p late which is attached to the outer face of the non-metallic filling in the head 5 member. f

Figure 5 is a modification illustrating the body member as provided with short extending end lugs.

Figure 6 is a view showing a portion of the 4@ inner face of one of the heads having recesses for the reception f the lug members on the.

body member as illustrated yin Figure 5.

It is 'found in the practical'enstruction of spools of this character, of advantage to provide a body member with heads at opposite ends thereof and to provide the inner faces of the heads with recesses for the reception of the ends of the body member and to so forni these recesses as to provide one or more keys or means for lpreventing relative rotation be- Atween' the body and the heads; also in some cases, it is foundof advantage' to provide a. filling of Wood or other suitable non-metallic material s et into'the outer faces of the head plates and to also provide a collar-plate secured to the outer fane of the filling member to which a tubular ,eqre'or other member may be secured forvthe purpose of tying the head members onto the body. ln some cases one of the flanged heads may be grooved to recelve a driving beltyand the following is a detailed description of the present embodiyment of my invent-ion showing one means by which these advantageous results may be accomplished With reference to the drawings, 10 designates the b ody of my improved spool which ispreferably formed of sheet metal rolled into tubular form with the ends of the tube forming a lap joint v11 at the seam, and on the ends of this body membenl preferably mount head members 12each formed from sheet stock comprisin an inner 'disc' plate 13 having an out-turne peripheral flange 19 with an inturned 'edge 20. The inner faces .of the disc plates are preferably provided i with an annular groove 14 for the reception of the-ends of the tub lar body 10. This an- Anular groove is also provided with an en-4 largement 1 5, see Figure 3, for the reception of the lap joint portion 11 of the body. The 'shouldersl of this enlarged recess 15 are for engagement with the shoulders 17 on the lap joint of the seam 11, whereby when this lap joint portion is inserted into this enlargement 15 in the annular recess of the v head, it serves as a key to prevent relative rotation .between the head and the body.v

In some cases it is found of advantage to p rovide a filling 18 of non-metallic material in the outer faceof the head member such as wood, vulcanized fibre or other similar material over which the outer edge 20 of the flange is turned. A` lt is also found of ad- 9 vantag to secure a collar-plate 21 to the 95 .outer face of the lling by forming spurs 22 bers and the edges 20 of the flange 19v rolled Over onto the before the head members are positioned onrto the body and after the ends of the tubular core are riveted or rolled to bind' the Whole together.

I do not wish to be restricted tothe use of over onto the outer facesofthe head members non-metallic material as a filler for the heads as this maybe omitted, if desired, and any other suitable cdnstruction may-be employed, neither do I Wish to be restricted to the emplyment of a central or tubular core 23 as any other. suitable means may be employed for securing `the heads ontothe body of this spool. A f

Instead of forming a continuousc annular I having recesses for receiving the ,ends of saidv body and provided With an outwardly-turned groove in the side faces of the head plates for the reception of the ends of the tubular body, I may form slight projections 23 on the ends of the tube as shown in Figure 5,

and provide corresponding recesses 24 in the head plates, as illustrated in Figure 6.

In some instances I may provide an annular groove 25 in the'periphery of one of the spool 'heads for the reception of the driving belt,

if desired.

i My improved lsp-ool is very simple, practical j The foregoing towards the' construction illustrated but I and inexpensive in constructio-n, is very easy to .assemble and 1s very strong and durable in its operat1on.-

description is directed solely desire vit to be understood that I reserve the privilege of resort-ing'tol all 'the mechanical changes to which the device is susceptible, the invention being ldefined and limited only by the terms of the appended claims.

I claim: l 1. A spool having a rolled sheet metal tubular `body with 'a seam longitudinally thereof and a projecting portion adjacent the seam at the end of said body, a head 'at 'sich end of thebqdy, the inn-e1 faces of said heads having imperforate recesses to receive i relative rotation of the body andA heads and I' joint seam, the inner faces of said heads be.

said projecting portion adjacent the seam and lock the seam closed and' also prevent means for lockingfsaid heads onto the ends of said body.. v l

2.- A spool having@ bdy' with@ heid ai.: eachend, said body being formed of sheet metal rolled into tubular form With a lap ing each provided with an annular recess into which the ends ofthe tube extend and 1 with an enlargement for the joint portion,

' ingand the part-s 4are prevented from relawhereby the joint is prevented from spreadtive rotation, and means for securing the heads to the ends of the body.

3. A spool having a body with a head at each end, said body being formed of sheet metal rolled into tubular form With a lap joint seam Withv lan `invvardly-extending shoulder, the inner faces of said heads being each pro-vided with an annular recess into which the ends of the'tube extend, andan peripheral flange, anonmetallic lling secured in each of saidheads byy its flange, a

core for securing said members .in assembled. relation, and means for preventing the relative rotation-of said members.

5. A spool comprising a tubular body member, head members at each end thereof having outwardly extending ianges, a nonmetallic filling` secured n in each'head by its fiange and having a central openingtherethrough, a collar-plate' on the outer surface of said lling.andllocated about said opening, and a core extending through `said body having its ends engaging said collar plates to hold the members in assembled relation.

. 6. A spool comprising a tubular body member, head members at each end thereof, each having an outwardly-turned peripheral Harige, anon-metallic filling in each head 'and the edge of said flange turned' inwardlyv therein, said heads having af central opening therethrough, a collar-plate on the; outer surface of said filling and located about said opening, and a tubular core extending Ythrough said body havingits ends engaging said collar-plate to lock the heads onto the ends of the body.

,7. A spool haying a tubular body With liead members at each end, means for preventing relative rotation of'the heads and body', non-metallic outer face on said heads,

a'collar plate on the outer surface of each of said faces having inturned spurs eX- tending thereinto vand a tubular core exi tending through the body and headmembers and engaging said plates to lock said head members on to the body.

In testimony whereof I aiiix my, signature.
