'v3 other as the cloth in travelling in frictional Contact with the slat-formed surfaceV of the device causes rotation of the Structure formed by the cylinder and slats. My object is .to improve devices of this class by increasing 55 the eciency and durability thereof, renden ing the construction simpler and the parts more easily assembled and disassembled, and insuring smoother and quieter a :tion and less resistance to rotation.
In the drawing,
Fig. 1 is a plan of the device;
Fig. 2 is a longitudinal section thereof;
Fig. 3 an end elevation;
Fig. 4 a Section on line 4 4, Fig. 2;
' f5 Fig. 5 a plan of a fragment ofthe main shaft and a cam thereon; and
Figs. 6 and 7 transverse sections of one of the movable slats in planes cutting its two guide members.
ff) An axial support is formed by ashaft 1 assumed to be held against rotation in any support and certain cam sleeves thereon to be described. v n
A cage revoluble around this support is constructed as follows: 2 designates a Pai11 of collar-like carriersv penetrated by the shaft and 3 denotes rods parallel with the shaft and arranged in different radii from the axis of the cage and each penetrating the-two carf riers. The Ycarriers and rods are secured together, against relative movement longitudinally of the rods, by split-rings 4 into which are tapped screws 5 which yare screwed in against end llanges 2m on the carriers vuntil the consequent expansion of the split-rings causes them to eXert clamping or binding pressure against the rods. In the ypreferred construction there are two other carriers 2a, split-rings 4a and screws 5a between the first 59 two vand united with the rods in the same way.
The shell is constructed as follows: Enf compassing each end portion of this cage is a cylindrical set of slats 6. Each slat has afv{iXedto it and extending inwardly a pair of guiding members 7 reaching between two of the rodsand grooved in its opposite faces, as at 7 a, the grooves being rounded and receiving both such rods so that thereby the Slat is slidable ylengthwise of and onthe rods; for securing each memberr 7 to the-slat saidmember has a stem 7b penetrating a hole-in the slat and having its outer end upsetvin the countersunk or enlarged part :of the' hole as lshown in Figs. 6.and7. The outer lmember 7 of each pair is equipped with a roller8 at the inner side thereof.l The rounded form ofthel grooves 7b insures movementv of lthe slats with the minimum of binding andv frictional rei sistance. Y yThebearings for the cageare affordedby outer races 9 secured with a` driven litin the several collars, inner races l() arranged with a sliding'fit on the shaft, andvballs 1.1 which run in the grooves of theraces. l Secured on the shaft by the set screws 12 .are the sleeves 13 which, being outward of the carriers 2 and abutting the races 9 and 10, confine the cage against endwise displacement'` and ywhich Lalso have the circumferential cams 18m-,here sinuous grooves. TheseA grooves receivethe rollers 8 kof theslats and are so formed and arranged as to cause each .two alined slats, as in thelrotation they passkr anygiven radius, to move toward or from each other-see Fig, 1, for example, in which, dueto the shape ofthe groove shown-in Fig; 5, the slats appearin different stages, the pair at the top of the figurel closest together and those at the bottom furthest apart'. g
Whatever thek distance between the abutments formed bythe sleeves 13 may be,since the carriersv are adjustablelengthwise of the i rods they may be set'apart the required disr tance, for instance soV that the abutmen'ts will, i
by abutting themoppose any endwise. Inovement of thecage, as shown in Fig. 2.
If the intermediatecollars 2a are present there will usually be vprovided the intermeditersunk screws 15. v-
While, in accordance 'With usual practice', the shell in the example vhas both ends sectional or in the form of the movable slats, it is to be understood that the invention in its essence is concerned With at least one end of such shell being composed of the movable sections or slats.
An advantageous feature of myv construction that when any rod becomes Worn by Contact Aof the rollers 8- therewith it may be released and turned around its own' longitudinal axisto present a fresh surface to the r'oller.l l y Y Having thusfully describedv my invention what I claim is: l
l. In a device ofthe class described, a revolving cage comprising a carrier adapted to be journaled on an axial support penetra-ting the same and having a sinuous circumferential cam, round rodsl extending lengthwise of and arranged in different radii from the axis of the cage and bearing against the cartier, and means, acting transversely of the rods, to, clamp them to the carrier, each rod being shiftable around its own lengthwise axis upon releasing said means, in combina tion With a shell encompassing said cage' and having one end thereof composed of a cir cum'ferentialv series of sections individually movable Von the rodsV toward and from the other end of the shell and each having means to engage the cam. y
2. In a device of the class described, a revolving cage comprising a' carrier adapted to be ournaled on an axial support penetrating the same and having a sinuous circumferentialcam,rods extending lengthwise of and arranged in diferent radii from' the axis of the cage and bearing against the carrier, a split-ring and screvv means engaging the carrier and split-ring and holding the latter in clamping engagement with the rods, in combination with a shell encompassing said cage and having one end thereof composed of a circumferential series of sections individually movable on the rods toward and from the other end of the shell and each having means to engage the cani.
3, In adevice of the class described, a re volving cage adapted to be journaled on'an axial support having a sinuous circumferential sup'port and penetrating the carrier, said cage .including cross-sectionally round rods arranged in a circumferential series, in com binat-ion WithaA shell encompassing the cage and having one-'end thereof composed of a series of sections individually movable toward and from the other end of the shell and each having guiding means projecting between tWo adjoining rods and formed with opposed rounded grooves receiving said adjoining rods, each section having means to engage the cam.
l. In a device of the class described, a revolving cage comprising a pair' of carriers adjustable one toward and from the other and adapted to be journaled on an aXia-l supporti having a sinuous circumferential cam and penetrating both carriers, rods extend inglengt-hvvise of and secured to one and having sliding contact lengthwise of themselves' With the other carrier, and means, common to the rods to clamp the rods to the latter carrier, in combination With a shell encompassing said cage and having one end thereof composed of a circumferential series of sections individually movable on the rods tovvard and from the other end of the shell and each having means to engage the cam.
In testimony whereof I aflix my signature.
JOHN E. PETERSON.
