BELT-FASTENER PLATE HAVING BEADED OR ROLLED EDGESf Specification of Letters Patent.
Patented Aug. 11,1908.
Application filed October 2t, 1906. Serial No. 340,758.
To all whom z't may concern:
Be it known that I, Gnonon FREDERICK BULL, a resident of Birmingham, in the county of \l'arwick, England, and Isaac JACKSON, a resident of'Glossop, in the county of Derby, England, both subjects of the King of Great Britain and Ireland, have invented new and useful Improvementsin Belt-Fastener Plates Having Beaded or Rolled Edges, of which the following is a specification.
These improvements relate to beaded or rolled edge belt fastener plates and the object of the invention is to provide such aplate which shall have the surrounding edge or edges completely or more than completely rolled or turned over on itself or themselves.
A complete or more than complete convm lution of the surrounding edge of a metal plate has not, before this, been attainable by the use of ordinary dies or stamping tools, but we are enabled by our invention to produce a plate with a perfect and beautiful beaded edge and in a very simple manner. "0 ,ell'c ct this by thinning or tapering the edge of the plate at some suitable stage in the process of manufacture, the thus thinned or tapered edge, ouing to its being less still than the remainder of the )late, readily adapting itself to the varying diameters or lengths of periphery through which it passes in the process of curling over, without in any way distorting or crumpling itself or any other part of the plate. According to the previous methods of beading such plates the edge has remained at its original thickness and inferior results have been attained.
The accompanying drawings illustrate a plate for use in a machine driving belt fastener produced according to this invention. The tools or dies by which the different forms of the plate at different stages of manufacture are produced are of the customary construction to effect their purpose, as is well understood in the art of metal stamping and pressing, and they are, therefore, not here Illustrated.
In the accompanying drawings, Figures 1 and 2 show in plan and edge elevation the flat blank of the fastening plate; Figs. 3 and 4 show in plan and longitudinal section the late in the second stage of its manufacture; ligs. 5 and 6 similarly illustrate the plate in a further stage of manufacture; Figs. 7 and S similarly illustrate the completed plate; and
Fig. 9 illustrates to a larger scale a sectional view of part of the completed improved edge.
As shown in Figs. 1 and 2, A is the metallic blank stamped out in the flat and formed with holes B for the passage of screws or or uivalents for use when the plate is used in a oelt fastener.
As illustrated in Figs. 3 and 4, the plate in the second stage of its manufacture has its edge turned up as at C 'approximatelv at an angle of about 90 to the original plane of the blank. 1X10 amount turned up depends on the extent 0 which the edge is to be subsequently curled or turned over. In the )articular plate described theparts surrounding the boltholes are also in this stage pressed to form concavities surrouinling the bolt holes in the It wcr face of the plate, and a corrugation or rid e is also formed between and connecting the con'itavities.
In the next stage ol tl ieproccss the turned wall C of the )late is'remlered thinner or tapered towards its edge a s illustrated in Figs. 5 and 6.
In the next and final stage of the process the result of which is shown in Figs. 7 and S the turned up tapered ed e is rolled over between suitable dies to Form a complete bead, the die against which the reduced edge of the flange comes being suitably carried to turn over and guide the edge.
In Fig. 9 is illustrated the path followed.
by the edge in the production 0 the roll.
The different stages in the production of a. plate may be varied from those described and illustrated, and the tapering of the edge may be accomplished at a stage before the complete turning up of the wall shown in l igs. 3 and 4, or during such turning up, but it is preferably accom lished subsequently thereto as herein descri )ed.
Although this invention is particularly plicable to plates or stanipings in whic 1 tie whole of the edge is to be CUIVC-Il over in a complete or more than complete convolution, it is also applicable for the more perfect production of plates in which the edge is not curved as far as a complete convolution and also to a curved or beaded edge which .11. a. wan...
within the np-tnrned w all forcin the blank forward in a female die, the walls of which are proportioned and tapered relatively to the male die to produce the required efleet.
No claim isherein made to the novel )rocess or method hereinbefore described as that will form the sul')jeetmatter of a divisional rounding each such bolt hole or bolt holes, and an inwardly rolled bead which consists of a part of theplate which has been tapered or thinned towards the edge, substantially as herembefore described and as illustrated by the drawmgs.
3. A metal belt fastener plate having a.

In testimony whereof we have signed our names to this specification in the presence of 3 two subscribing witnesses.
