METHOD OF MAKING CYLINDER RINGS.
'APPLICATION FILED JULY 13. 1916.
12155775 Patented Feb. 13, 1917.
rm we MTENTIWFIQE JAMES eAn'PnELL; or s'r; LOUIS, MISSOURI, ASSIGNOR ros'r. Louis FELL NG MACHINE COMPANY, or s'nrouis, MISSOURI, A CORPORATION or MISSOURI.
To all who m it may"concern,
Be. it known. that/I, JAMES CAMPBELma citizen of the United'States, residing at St.
1 Louis, in'the State. of Missouri,' have invented certain new n 'and useful Improvements in Methods of Making Cylinder tion.
. Thisinventionrelates to improvements in the method ot-manufacturing split rings, and more particularly to a method of forming the inside member of a two-piece cylinings, of whichthe followingis a specificader packing ring, thep riphery of which grinding a plurality of'split rings to proper size. I
A still further object-of the invention is to provide a method of forming from a long 'strip of metal a plurality of accurately ground split: rings, all being ground simultaneously. p j 1 Still other and further-objects will become apparent to those skilledin the art fromaconsideration of the. following description and drawing, wherein-3:
- Figure .1 is a side elevation :of a mandrelsuch as maybeemployed for carrying outmylinvention-wi'thfa strip of metal spirally wound thereom one end being broken away to illustrate the cap attachment for the end of the mandrel used when aneccentric'ring is desired' ;Fig. 2 is an end e'levationof-the device shown in Fig. 1, the end cap being removed. "Fig. 3 is a similar view. from the 'end.
Fig. 4 is, anendview with-the eccentric proved method of forming split rings I shown in; the drawings a simpleco grinding ea in place, and; e I I Fig. 5 is perspective view of a finished ring.
For the purpose of illustrating "my imhave tionvwhich may be utilized wage of a cylindrical accurately formed mandrel 10 havlng reduced end portions 11,
12, provided with lathe respectively;
centers 13:; and 14,
fThe end of the mandrellO: adjacent the reduced portion 11 is provided with'a slo which takes through from the any ground split ring from a'strip of- METHOD or MAKINQCYLlNDER-RINGSn Patented Feb. is, 191 7..
Application filed July 13, 1916. Serial No; 109,156.
' 15 adaptedto'receive one end 16 of the strip from which the rings are to be formed. 4 In order to rigidly 'secure this endl6 of'the strip in position 'within'the slot 15, I have provided a radially extending setscrew 17 periphery. of the mandrel'into the slot;
A long metal strip Of a width equal to the desired width of the completed ring is secured atoneend 16'within the slot 15, as above described and is then wound spirally about the mandrel 10 as indicated in Fig. 1.
The spiral is wound tight so that the sur-.
1 faces of the convolutions are in close contact with each other, thus forminga continuous tube or shell surroundingthe mandrel 10.
The opposite end'of'the strip is then secured under a clamping. stud 18,'taking into the opposite end of the mandrel.
The spirally formed shell is now ready for grinding to the desired size, and if the exterior of the ring is'to be concentric with the interior surface, the mandrel may be set in a lathe or grinding machine, using the centersl3 and 14 upon which the mandrel .Was mounted when it was initially j formed with its cylindrical surface. Onthe other hand, if the periphery of the rings, when completed, are to be ec'centric-to-the inner surface I have found that a convenient way to provide offset centers upon which to grind the shell, is to secure on each endof the"re duced portions 11 and l2 of the mandrel a pair ofcaps, as 19, the inner diameter of which is formed to make tight fit with the reduced ends 11 and 12 of the mandrel and the outer ends of which are provided with lathe centers 20, slightly offset from the axis of the cap. To prevent rotation of the mandrel with respect'to "the cap I have formed an'opening 21 in the end of each endof the mandrel for registry with the holes 22 of the cap and into which projectsa stud 23. Different sets ofcaps may be provided Withtheirlathe centers'having different degrees of eccentricity depending upon the degree of eccentricity on which the peripheries of the rings are to-be formed.
' The next operation, after having mounted the. mandrel in the centers of the lathe or grinding machine, is to grind the periphery .91 the tubular shell to therequired diameter.
I then secure or clamp the shell by suitable means ZIHd-SiLW-Cllt through each convolution of the coil on a line parallel with a metalstrip to a round mandrel, winding the convolutions in close contact, one with another, securing the opposite end to the;
the axis of the drum as indicated the dotted line 25in Fig. 1. This separates the spiral into.a'plurality of 'rings, such as indicated at-26, in Fig. 5.
g 7 ;By means of this'method I am able to form a large number of perfectly shaped expanding rings by one set of operations, the rings being accurately formed'a's to size and uniform as to expansibilityand other qualities.
Whereas I have illustrated simple appara- I tus by means ofwhich my'method maybe 1 carried out, it is obvious that various changes may be made therein withoutvdeparting from the spirit and scope of thefo'L lowing claims.
