United States Patent 3,015,915 CLINCHING HUBS FOR BUFFING RINGS Isidore Heeht, 2690 Saw Mill Road, North Beliniore, N.Y., assignor of one-half to Milton Hecht, Dumont,

Claims. c1. s1 193 The present invention relates to improvements in buffing wheel construction and more particularly to a hub for securely holding a fabric buffing ring; said hub being mountable on an arbor.
The principal object of this invention is to provide a one-piece buffing wheel hub of novel and improved construction which is mountable on an arbor and offers a clinching ring to support and secure a fabric bufiing ring thereon.
Another object thereof is to provide a novel and improved one-piece buffing wheel support and mount of the character mentioned, which can be easily stamped of sheet metal.
Although attempts have been made heretofore to mak a one-piece bufling wheel hub of sheet metal by having a disc with central hole so that it could be mounted on an arbor, and by having radial teeth formed of its perimetral lane and bent in staggered relation to receive a buffing ring between them, the number of clinching teeth at each face of the bufling ring could only be those formed of one half the said lane.
t is therefore another object of this invention to provide a novel and improved one-piece bufling wheel hub of the kind set forth, which afi'ords that all the teeth formed of its outer peripheral lane shall be available for one face of the bufiing ring and that a set of companion teeth be available for the other face of said butiing rlng.
A further object hereof is to provide a novel and improved onepiece bufiing wheel hub having two full sets of companion clinching teeth of maximum number, and offering a continuous ring seat for the support of the inner edge of a bufling ring. Heretofore in one-piece constructions, the seat ofiered the butting ring, was segmental.
Still a further object of this invention is to provide a novel and improved one-piece clinching and mounting hub for a buifing annulus, having the attributes mentioned, which is reasonably cheap and easy to manufacture, light in weight because heretofore in items of this class, two secured-together plates had to be used to get two sets of clinching teeth of maximum number, and further, my new construction is easy to use and eflicient in carrying out the purposes for which it is designed.
Other objects and advantages will become apparent as this disclosure proceeds.
For the practice of this invention, the clinching hub taught herein may be made of a steel, round dish-shaped member having an outward flange around its rim. One set of clinching teeth or prongs are formed of said flange and a companion set is formed of the material of the outer perimetral lane of the dishs bottom. A central hole in said member is provided with a flange therearound extending within the dish, to support the hub on an arbor. A fabric butting ring is supported on the round wall of the dish member and the teeth are bent in to penetrate said bufiing ring and thus secure it to the hub.
In the accompanying drawing forming part of this See specification, similar characters of reference indicate corresponding parts in all the views.
FIG. 1 is a bottom view of a circular dish-form from which I make the clinching hub taught herein.
FIG. 2 is a section taken at line 2-2 in FIG. 1.
FIG. 3 is a fragmentary enlarged perspective view showing the manner in which the clinching ring part of said hub-is constructed; only some of the clinching teeth being shown.
FIG. 4 is a section taken at line 44 in FIG. 3, drawn to a reduced scale.
FIG. 5 is a face of a completed bufling wheel comprising the clinching hub of FIG. 4 with a bufling annulus mounted thereon and secured thereto by the sets of teeth.
FIG. 6 is a section taken at line 66 in FIG. 5, drawn to an enlarged scale.
It may be noted that FIGS. 1, 2, 4 and 6 are drawn to the same scale.
In the drawing, the numeral 15 designates generally a one-piece, round dish-shaped member having an outward flange 16 around its rim, so that the circular wall 17 is perpendicular to both the bottom 18 of said dish and said flange 16. The bottom of this dish is formed with a short inward nipple w around a central hole 20, so that said member may be mounted on an arbor as the hub of the buifing wheel denoted generally by the numeral 21. Spaced pieces are punched out of said flange 16, whereby pointed, radially extending teeth 22 are formed of said flange and then bent, and a set of companion teeth 23 are struck of the material of the outer perimetral lane A of the disks bottom 18, whereby their roots are on the perimeter of such bottom; such companion teeth 22 being bent from the bottom of the dish to lie radially outward opposite the set of teeth 22 formed of said flange 16. It is preferred that the teeth of said sets, be in staggered relation. The holes 24 formed in the bottom of the dish, serve for ventilation. The inner edge of a fabric bufiing annulus 25 can then be supported on the circular wall 17 of the hub member 15, which with said sets of teeth 22, 23 constitute a clinching ring to secure the bufiing annulus 25. In usual fashion, the teeth are entered into the bufling member 25 by being bent towards each other respectively as is shown in FIG. 6, to secured the assembly.
This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiment shown herein be deemed merely illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; referfence being had to the following claims rather than to the specific description herein to indicate the scope of this invention.
I claim:
1. A one-piece clinching hub for a bufling ring, comprising a round dish-shaped member consisting of a ring wall adapted to support the inner edge of a buffing ring and a bottom closing one end of said ring wall; said member having an outward flange around the other end of said ring wall; said bottom having a central hole whereby said member is mountable on an arbor; a multiplicity of radially outwardly extending teeth being formed of said flange and a multiplicity of radially outwardly extending teeth being formed by being struck up from the 4. An article as defined in claim 1, wherein the ring 10 2,291,524
4 wall is everywhere equidistant from the axis of the dishshaped member.
5. An article as defined in claim 1, including a nipple within the dish-shaped member; said nipple being a flange around the hole in the bottom of said member, for supporting the latter on an arbor.
