To all iuhom it may concern:
Be it known that we, CHARLES ALGERNON B., a subject of the King of- Heaton \Vorks, Ne\vcastle-upon-Tyne, in the and- Eowni Uni-nines CARN'P, a subject of the King of Great Britain and Ireland, and residing at last Cowcs, Isle of Wight, England, have invented certain new and useful'lmprovements in Methods of Securing Metal Strips in Grooves, of which the following is a' specification.
. This invention relates to the securing of packing or blade strips in turbines and 1:0- tary compressors. The ordinary. method of securing such strips in their grooves, is to calk the strip itself or a sepa'ate packing piece in the groove or to calkthe edges of the metal of the groove in which they are placed.
The object. oi the present invention is to secure the strips in the groove by rolling in such a manner that creeping of the strip in relation to the holding member even during the rolling process is prevented. v
The invention consists in securing blade or packing strips in grooves, especially grooves around a cylindrical surface, material of the strip or of a separate packcalking tool in-such a manner that the edges 'ofthe strip. shall rovide a serrated grip against the walls of t e groove in th carrying member.
A convenient form of apparatus is illustrated in the 'accompanymgdrawings for carrying this invention into practical efiect.
' method. of applying Figure 1 representsone form of the apparatu's 6.9; att e endv ofia'radius'arm' carried on a boring bar; Fig. 2 illustrates another the apparatus, 6. g. when the tool is supported in the rest ofthe strip aftit has-been nurlin fixed in position by Acco rcling-to Figs l and2,'we use a roller,

by rolling the or of the groove instead of using be done on the strip oron Patented Au .10, 1909.
a, milled or grooved as shown which, in the case of rolling a' strip or the like in the grooves onthe rotating member of the turbine, is carried on a slide rest of a lathe or similar support as shown in Fig. 2. \Vhen however, the rolling is to be effected on the cylinder orcasing of the turbine or the like, the nurling tool is carried on an arm such b, (Fig. 1) attached to the boring bar and in both cases the nurling tool is pressed against, the packin or other'strilps'or part it is desired to call; in'any convenient way, as for instance, in the last. mentioned case by a screw operating a wedge with an inclined slot.
In the, enlarged views Figs. 3 and 4, the strips, 1', v, are shown as heldin by nurling the casing-or other part in which the strips are fixed'but if desired the strip itself may be knurled. I
By this invention an exceedingly chea and quick method of securing blade an packing strips is obtained. Further by nurling the strips in accordaiu'e with this invention, we avoid straining or bending of the turbine spindle or casing. Some further advantages of this method are that packing or blade st 1'] p is pressed transversely 1n the groove so as to cause it to fill the groove without materially stretching the strip longitudinally, and that when the milled roller'. is used it makes a serrated locking joint between the strip and groove which effectually. )revents end movement or creep, which may l)8 caused by varyingtemperatures.
Although we have only illustrated ourinvention applied to packing strips, it will be readily understood tha't it may be used for etfe'eting the fixing of all kinds of strips used in turbines, such as the (talking strips or the blade carrying strips, and-the nurling may the casing as shown or on both. a Q 7 Having now described our invention, what we claim as new and-desire to secure by Letters Patent is 1 1.
