HENRY G. THOMPSON, OF CLEVELAND, OHIO.

PRESSED METAL WHEEL.

Application filed may 2, 1921.

To all whom it may concern:

Be it known that I, HENRY G. THOMPSON, a citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Pressed Metal Wheels, of which the following is a full, clear, and-exact description.

This invention relates to pressed metal wheels and more rticularly toa construction which is particularly adapted where the load to be carried by the wheels is a light load, as for instance, toys, although the use piffiihe Wheel is not limited to this particular One of the objects of the invention is to produce a pressed metal wheel from sheet metal by a stamping process, which may be easily formed and easily assembled, but at the same time making quite a rigid structure which gives the wheel suflicient strength for use with light loads.

Reference should be had to the accompanying drawings forming a part of this specification in which Fig. 1 is a side elevation of a wheelj Fig. 2 is a section upon the line 2-2 of Fig. 1; Fig. 3 is an elevation of one of the stampings which is used in producing the wheel; Fig. 4 is a section upon the line 4 4 showing portions of the two stampings used; Fig. 5 is an elevation of a modified construction and Fig. 6 is a section upon the line 6-6 of Fig. 5'.

Referring to the drawings, which-show the herein described invention, 1 indicates a' stamped' metal disc which is adapted to cooperate with a second stamped metal disc which is indicated at 2. The disc 1 is formed from a blank piece of metal and provides a rim portion 1 and a central hub portion 1 and radiating spokes 1. Thisblank forms in effect half of a wheel and the spokes are formed half round with intermediate spaces formed by severing the metal. The hub is provided by forming an outwardly flaring" portion as indicated in Fig. 2 and is providedwith an inwardly extending flange 1 The rim portion of the wheel is formed with a rounding portion and also with a straight flange 1 which extends outwardly from the rounded portion 1.

a The member 2 of the wheel is formed with central spoke portions 2 which are formed precisely the same as the spoke portions 1 and having intermediate portions-between the spokes cut away. The hub portion 2 Serial No. 466,131.

is pressed outwardly the same as the portion 1 and the hub portion has an outwardly extending flange 2 which is similar to the inwardly extending flange 1, except in the present instance the flange 1 is cupeshaped as clearly indicated in Fig. 2. The rim portion of the wheel is indicated at 2 and it is formed as a half round ortion bein of substantially the same ra ius as the alf round portion 1. v

The two halves of the wheel land 2 are assembled by bringing the spokes so that they superimpose and the edge of the half round portion extends within the flange 1 as indicated in Fig. 4.

When the two halves are thus assembled, the flange 1 is by a pressing operation bent into contact with the outer surface of the half round portion 2 as indicated in Fig. 2 and additionally an eyelet 3 is inserted through the central openings of the hubs so that the flange 3* comes against the flange 1 and when in this position the eyelet is expanded at the other end so that the expanded portion 3 fits against the flange 2.

The member has been described as an eyelet, because in small sized wheels, such for instance as those having a diameter of approximately 2 inches or thereabouts, an ordinary copper eyelet, such as is well known on the market, may be used.v However, it will be understood that no *limitation is intended to this precise eyelet as any cylindrical shaped member which may be pressed into contact with the hubs 1" and 2 may be used with good results. The member- 3 should of course be hollow so as to permit the wheel to be mounted upon the axle of the toy or vehicle in connection with which it is to be used. I 0 v The construction which has just been de- ICE.

scribed is exceedingly simple and one which are in contact enables the structure to becompleted by folding the straight flange 1 around the half round portion '25, thus'not only completing the rim portion of the wheel, but effectively joining the tWo halves of the Wheel at the rim portion,

In Figs. and 6 there is shown a modified form of construction, which, however, is only modified to the extent that the spokes 5 and the intermediate portions 6 of the wheel are maintained in unitary form, the spokes being merely formed by throwing a bead into the sheet metal which of course stiflens the sheet metal perceptibly and gives the impression of spokes.

The formation of the rim portion and the formation of the hub portion of the wheel as Well as the manner of assemblying the two half portions of the wheel and securing them together are the same as that which has previously been described.

Having described my invention, 1 claim:

1. A. sheet metal wheel formed off-two cooperating annular parts each of said parts being formed with a central opening and a hub portion surrounding the-same, each of said parts at the periphery being formed with a substantial half round portion which are oppositely disposed when the parts are assembled, the edges. of one of the half round portions extending over and beyond the edge of the other of saidportions and the half round portion which conforming to of said parts having interit overlies, each mediate portions between the hub and the half round portions "which lie in contact with each other, and a sleeve member'which wheel formed. of two co-' portions extending over and beyond the other of said porti s and conedge of the the half round portion which it forming to overlies, each of said parts being formed' with half round spokes which extend between the hub po'rtion andthe half round portion'the edges of said spokes on the opposite wheel parts engaging, and a sleeve member extending between the hub portions of the wheel parts and connecting and holding them together.

In testimony whereof, I hereunto afiix my HENRY e. THOMPSON.
