ROBERT R. WARE, OF CHICAGO, ILLINOIS.
ROLLER.
Application led March 13, 1926. Serial No. 94,474.
My invention relates to rollers, particu` larly for roller skates, and is an improvement over the form shown in Patent No. 1,469,344 granted October 2nd, 1923 to 5 l/Valter Ware of Chicago. In the earlier type, in addition, to the hub and tire, four principal members were employed, viz two side plates or bushings and two rings located on either side of the bushings and the bushings and the tire between them. ne object of my invention is to simplify the prior construction and to produce a roller consisting of four principal parts in contrast to the six principal parts which were required in the previous type. Another object is to provide a construction such as to simplify assembly of the parts andto produce a more accurate roller by avoiding the possibilities for inaccurate adjustments present in the previous construction. Another object isto eliminate the er' rors apt to arise in mass production due to variations in configuration of the parts which my invention makes superiiuous.
Still another object is to improve the rigidity of the structure by forming side plates which lend themselves to a crimping or indenting operation after the parts are assembled, to thereby tighten the tire to a t greater extent than 1s possible by ordinary rivets alone.
I accomplish my objects by the mechanism illustrated in the accompanying drawing, in whichc Figure 1 is a side view of a complete roller.
Figure 2 is an axial section thereof; and
Figure 3 is an axial section of the different component parts separated suiciently 40 to show their individual construction and at the same time indicate their relationship when assembled.
Like numerals denote llike parts throughout the several views. According to my invention the hub 1 has an annular race 2 for the 'anti-friction balls 4 in the known manner. The tire 6, which may be of vulcanized rubber or other suitable substance, has an internal dovetail A ange 8. These arts are the same as in th type previously own.
According to my invention, but two additional parts are principally required for completing the structure. T ese two parts are identlcal in form and consist of side plates of pressed metal having peripheral danges 10 and central openings 12 of suiiicient diameter to loosely accommodate the hub 1. Viewed from the inner side these plates have annular ribs 14 which bear against each other and result in the formation of arches 16 which together constitute raceways for the balls. as spacers to hold the arches at the proper distance apart, and as spacers to hold the iianges 10 at the proper distance apart. Thus itis a two-piece structure which forms the body ot the roller, that is, the entire connection between the hub and the tire.
When assembled, the side plates are held together by rivets 18 which pass through the peripheral flanges 10.
Ordinarilyafter assembling, the roller is placed in a press which makes annular depressions 20 in the iianges between rivets. This not only causes the metal to sink into the tire flange but also presses the plate flanges tightly against the sides of the tire flange, and makes a very tight, rigid structure. v
From the foregoing it will be seen that my roller consists :of but four principal piecekthe hub, the tire and the two side plates. This results in several advantages over the type shown in the above mentioned patent. In the lirst place only two pieces need be handled instead of four, and these two pieces are identically alike. In the second place the assemblage is greatly simplified for in the revious construction it was necessary to bring all four of theparts together 1n a particular way so that they would interlock, and this not only consumed time but there was always a possibility that some of the parts would not be of true form Thus the ribs act "or would,when riveted together, be drawn out of proper position, thus making a roller for it makes possible production of a lighter,
truer wheel at a reduced cost for both labor and material. I
Having thus described my invention what I claim as new and desire to secure by Ietters Patent is: y 1. A ball bearing roller having a hub proviei with n receway for the bells, a tire having im internei circular Harige, :md two annular pressed metal side Plates of idenii cal form erich having marginal flanges for engaging the sides of the tire ange and cir cular ribs on J@he inner side forming internal arches which together constitute a, raceway for the balls, the rihs being adapted to hear against each other to thereby space the arches and the peripheral flanges which en gage the tire ange.
9:. A ball hearing roller having a hub proi. vided with n. racewsiy for the halls, a tire having an internal circular Harige, and ai two-piece structure i'orrning the connection mienne between the huh and the tire, the two pieces consisting of pressed metal annuler plates of identical form each having e central opening for loosely aeeommodatin the hub, a margnai Hange for engaging tie tire ange and an internal rib, the ribs forming internal arches constituting meeweys and contacting each other to thereby space the arches and the marginal iinnges, .and means assng Athrough the marginal fianges for hol ing the entire structure assembled.
In Witness whereof, I have hereunto subscribed my naine.
ROBERT R. WARE.
