Description

H. C. ROTH Nov. 28, 1933.
Filed March 31, 1932 INVENTbR. HARRIS C. ROTH ATTORNEY Patented Nov. 28, 1933 UNITED STATES Bendix Aviation Corporation,
South Bend,
Ind., a corporation of Delaware Application March 31, 1932. Serial No. @2301 3 Claims.
This invention relates to brakes and more particularly to drums therefor.
Broadly, the invention comprehends a brake drum, and means for supporting the drum, so that drum deflections, temperature, and expansion due' to temperature, will be substantially uniform. The structure also provides for means for eifectively cooling the drum and means for supporting the drum atthe points of greatest shoe pressure. The structure further affords reduced rim temperature with a small drum clearance due to the radiation shields between the drum and supporting means.
An object of the invention'is to provide a drum and means for supporting the drum including air cooling means.
Another object of the invention is to provide a drum and means for supporting the drum at the points of greatest shoe pressure.
Another object of the invention is to provide a drum and means for supporting same so that drum deflection, temperature, and expansion due to temperature, may be uniformly distributed.
A feature of the invention is a drum and a shell supporting the drum having lugs or rivets pro= truding from its inner periphery to engage the outer periphery of the drum.
Other objects and features of the invention will appear from the following description taken in connection with the drawing, which forms a part of this speciflcatioin, and in which:
Figure .1 is a side elevation of a drum and a supporting member therefor, parts being broken away to illustrate the relation of the drum to the support member;
Figure 2 is a side elevation partlybroken away, also showing the relation of the drum to the support member; and
Figure 3 is a modification.
Referring to the drawing for more specific details of the invention, 10 represents a cylindrical member having one end closed as at 12, and its other end provided with a circumferential flange 14. The member 10 has thereona plurality of studs or rivets 16 arranged in spaced relation and centrally between the ends of the cylindrical member, the purpose of which will hereinafter appear.
Positioned concentrically within the member 10 is a drum 18. The outer periphery of the drum is supported on the studs or rivets 16 with the inner end of the drum in spaced relation to the closed end 12 of the cylindrical member 10. The outer end of the drum 18 has formed thereon. a circumferential flange 20, the over-all diameter of which is equal to the over-all diameter of the flange 14. The flange on the cylindrical member 10 is secured to the flange of the drum 18 as by bolts 22 with suitable spacers 24 interposed bem tween the flanges 14 and 20.
' A modification'of the invention is illustrated in Figure 3 wherein the cylindrical member 10 is provided with two rows of studs or rivets 16 suitably spaced to support the drum within the cylincylindrical member or shell and the drum to effectively cool the drum.
Although this invention has been described in connection with certain specific embodiments, the
principles involved are susceptible of numerous other applications that will readily occur to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims.
Having thus described the various features of the invention, what I claim as new and desire to secure by Letters Patent, is:
1. A drum comprising concentrically arranged members having circumferential flanges of the same over-all diameter, means for securing the flanges together and in spaced relation, and means for supporting the members in spaced relation. v
2. A drum comprising concentric members, spacers between the members, circumferential flanges on the members, and means for securing the flanges together including means for spacing the flanges apart.
3. A drum comprising a cylindrical member having one end partly closed and a circumferential flange on its other end, spaced support members secured to the cylindrical members protruding inwardly, a drum supported thereby, a flange on the drum having an over-all diameter equal to the'over-all diameter of the flange on the cylindrical member, and means for securin the flanges together including means for spacing the flanges apart.
