This invention relates to mechanical toys such as a toy hoist or thelike, havingin its structure an elementwhich is adapted to re! ceive a cord to be wound thereon, the inv n- 5 tion being more especially directed to a novel structure of thetoy element or drum for re ceiving the solder the like. The principal object of thisjinvention is to 7 provide an improved toy drum structure,; owhich will be economical to manufacture and suitable for use in mechanical toys or the like." r

In a more specific aspect the invention re lates to atoy drum or thelike having a hol- 5 low cylindrical body and end plates to which the body is secured. A further object ofthe invention 'is to provide a structure of this type in which sheet metalpartsmay be used.

and in which means is providedfor securing form a substantially rigid structure. r r i The cylindrical body ofthe drum of the 1 invention is preferably bent out of sheet material and a still further feature of the in 25F'ventionresides in a novel means for securing the abutting ends of the cylindrical body:

whereby they will not open up or bulge alongthe joint formed between them. 1

An additional object of the invention is 5 auto provide a drum having an efficient but simple means thereon which may beengaged.

by a brake to retard or prevent rotationbit' the drum. An additional object of the JIIVGIItlOILlG- 35 sides in a novel method of making drums or similar elements for a toy construction.

To these and other ends the inventionconsists in the novel features and combination of parts to be hereinafter" described and 1 45 of this invention is included; l

The toy shown inFigs l and2 illustrates i one use for a toy element or drumembodying the features of this invention- 1 This toy 'is provided witha hoistingmechanism com prising side plates 10.111101 ll,a -bas e plate12, and drums 13, I4and'15Q-nponwhichcords simulating ropes are .adapted to "be wound andunwound toi operate pther-partsof the 5 toy (not shown) j detailed description of the {structure and operationjof a toy of this type may be found in a co-pending application" of fEdwardf- N..JAnketell, Serial No; Each of the-drums l3; l4 and1'5 are, in thistoy,.se cur edto ashaft lneansrof a set screw" 16 which threaded hrough a bush-j ingjl 'f securedto each druml The druinf shafts are journaled atthefends thereof in the-7 v sideplates 10 and .11. 1 It is obvious thatby omitting the; screw 16,: each drum wouldbe I adapted tocrotateupon itsrespective, shaft. The drums 13 and 15'farefofsifnilar cons structio whiledrum 121 is of somewhat iii'odified for bein royided atone endwith an additional? flangepart to adapt it fforuse as a brake d'rum. In the manufacture of drums-like 13' and- 15, a strip of sheetmaterial, 1 preferably metal, is formed by first stamping out a blank, l8,*as"illustrated in Fig. 8, andthen bending itiihtoa cylindricalf shape togforln a body part 2100f the drum.f To ues 21 and 22;"fornied fup on bojtliijof the end edges or the blanlr li; are then passed through suitable perre uonsy 23, provided in adisk 24.of:sheetmaterialy preferably me'tal, and-immed ovenupon' the outersurface} thereof, preferably being? directed The perforations 23 "are the "form of arcuate slots and are s'paced'apart about the i i diskan amount equal'tothe spacing between l the tongues 21 and 22.

modifiejclformf 1 The. tongues 22; 10d

are disposed at the side edges and 26 thereof, and are of a width which is substantially one-half the width of the tongues 21. When the body part 20 of the drum is assembled to the disk 24;, the tongues 22 at each end thereof are passed through the same perforation 23. This arrangement insures that the side edges 25 and 26 of the blank 18 will be in abutting relation and that the drum will not open up or bulge along this joint. 7 V

The disks 24 are provided with a cord receiving perforation 27, through which an end of the cord may be passed and tied to secure it to the drum. The disks 24 are larger in diameter than the drum body part 20 and form end flanges for the drum to retain the wound up cord thereon. The bushing 17 having a shaft receiving opening 28 therein, is secured to each disk 2 f by having a reduced end portion 29 thereof passed through a cen' tral perforation 30 in the disk, and riveted over upon the surface thereof, as at 31.

In the modified form of drum as shown in 7 provision is made for its use as a brake drum as at 14c, Figsi'l and 2. The tongues 21 and 22 at one end of the drum body 20, are passed through perforations in a disk 24, and in a flanged disk 34, both of which are secured upon a bushing 17,.as above described.

The disk 34 is formed with an outwardly directed flange part 35, from which the material eXtends radially outward to the periphery of the disks and parallel with the disk 3d as at 36. This structure provides, in combination with one of the disks 24, a brake receiving groove 37 about the periphery of the parts. The groove 37 is formed by the flange part 35 as a bottom, and the spaced apart portions, 36 of the disk 34. and the rim of the disk 24: as the sides. In use, as illustrated in Figs. 1 and, 2, a part of a resilient brake member 38 isdisposed in the groove 37.

F rom the above description of my invention and its mode of use, it will be readily understood that I have provided a relatively,

simple form of a drum or like element which, while being relatively light and therefore suitable for use in toy constructions of the type illustrated, is nevertheless rigid and strong enough to stand the use and abuse to which it may be subjected by a user of such a construction. The arrangement is such that when the cylindrical body of the drum is made of sheet material bent into shape, the abutting edges of the cylinder are effectively secured against relative displacement.

While I have shown and described a pre-. ferred embodiment of my invention, it is understood that it is not to be limited to all of the details shown, but is capable of modification and variation which will lie within the spirit of the invention and the scope of the appended claims,

'What I claim is: 1

1. In a toy drum structure, a cylindrical body part, a flange part at each end of said body part, a disk abutting one of said flange parts upon the outer surface thereof, and having its peripheral edge spaced outwardly from said flanged part to form a brake groove therebetween, and integral portions of said body part extending through each of said flange parts and said disk to secure said parts together. a

2. In a toy drum structure, a cylindrical body part, a flange part at each end of said body'part, one of said flange parts having a shaft receiving. bushing secured in an opening at the center thereof, a disk abutting one of said flange parts upon the outer surface thereof, and having its peripheral edge spaced outwardly from said flange part to form a brake groove therebetween, a shaft receiving bushing secured'in an opening in the other of said flange parts and in said disk to secure these parts together, and integral portions at each end of said body part extending through the adjacent flange part and at one end through said disk to secure said parts together. V

In witness whereof, I have hereunto set my hand this 17th day of April, 1928. V
