Description
May 9, 9 3- c. c. HALL METHOD OF MAKING PACKING RINGS Filed March 31, 1930 INVENTOR Char/w 0. Hal! BY 6% AH TERNEYS atented May 9, 19 33 UNITED STATE.
PATENT OFFICE CORPORATION, OF KALAMAZOO, MICHIGAN mn'rnon or MAKING PACKING RINGS Application filed March 31, 1930. Serial 110,440,355.
' The main objects of this invention are:
First, to provide an improved packing ring which may be formed of several kinds of metal, these being quite uniformly distributed throughout the'ring. v
Second, to provide an endless packing ring made up of metal foil which is of uniform dimension and of substantially uniform den sity throughout.
Third, to provide a method of making packing rings of metal foil which enables the very rapid production of packing rings havi-ng the advantages above indicated.
Ob ectsrelating to details and economies v of my invention will appear from the deone of the steps of making my improved packing ring, namely, the twisting of metal foil into a strand.
Fig. 3 is a fragmentary perspective view.
illustrating another step of my method, namely, the compressing of the strand of spirally twisted metal foil intoa flat strip.
Fig. 4 is a fragmentary plan view illustrating the manner of cutting or punching the rings from the strip shown in Fig. 3.
, Fig. 5 is a perspective view of my improved I packing ring.
In the practice of my method, I twist a plurality of strands of thin metal or metal foil as 1, 2 and 3 into a strand 4,-the metal being spirally twisted as indicated. The thin metal strips maybe of different kinds of metalas, for example, lead, copper and treated aluminum.
4 Prior to twisting into the strand, the strips pockets so that it does not escape when subjected to pressure.
The strand 4 is rolled or pressed into a flat strip 5 as indicated in Figs, 8 and 4 and the rings 6 punched from this flat strip as indicated by dotted lines in Fig. 4. These rings- I are of practically uniform density throughout, have very substantial strength, maybe rapidly produced and in use present very uni .form surface to the parts packed. 0
In Fig. 1 I illustrate a punch which I have found very satisfactory for the purpose,this consisting of a'bed member 7 having a pair of female die members 8 and Qdisposed one within the other, the member 8 being sup- 6 ported on a shoulder 10 within the bed n1en1- her while the member 9 is yieldingly supported by the spring 11. The punch head 12 carries the male member 13 having a collar 14 secured thereto providing in effect a sec- 0nd .die member, the member 12 coacting with the female member 9 while the member 14 coacts with the female member 8 so that the rings 6 are formed on a single actuation of the plunger.
My improved packing rings are very economically'produced, the rings being endless and of uniform density and of substantial Strength. Where a plurality of metals are used these are quite uniformly distributed 3 throughout the ring.
Having thus described my invention, What I claim as new and desire tosecure by Letters Patent, is: I The method of making packing rings consisting of spirally twisting a plurality of strips of metal foil into a strand, compressing the strand into a flat.strip of uniform thickness, and punching the rings from the strip.
Inwitness whereof I have hereuntoset myhand.
CHARLES C. HALL.
