I1,6 July 12 1927 G. B. 'HANDLEY ET AL 35 363 ENDLESS GONE BELT Filed May 6, 1926 wf/Woes,
vnarran sr GEORGE BERNARD HANDLRYv ANDl ENDLESS GONE BELT.
Appneation filed May e, 1926, serial Nn'. 107,188, ana in Great :Britain 'Januarya1e2a The present invention relates to improvements inendless cone belts designed for use on the cone drums of the drawing and speed frames of textile spinning machinery. These belts are now formed of two plies of leather, the outer ply of greater width than the inside ply. This belt construction reduces the actual frictional contact of the belt on the drum to a minimum while the frictional ply is supported by a Wider ply which takes up most of the pull of the load and at the same time compresses the 'narrow frictional ply on to the surface of the cone drum. The inside ply is made up of soft and resilient leather which in use either compresses or extends while passing over the drums or between them, thus actingl as a cushion and minimizingl various torsional strains to which the belt is subjected owing to the opposing planes of the cone drums. The ,outside ply is made of firm stretched leather adapted to resist tension and fork action. Y
Owing to the vertical drive and the consequent extremel tension to which the belts are subjected and the high temperature of the textile spinning rooms, these belts become exceedingly hot in use and this heat quickly destroys the efhciency of the insideply by cracking the grain of the leather and ultimately breaking said ply; In the same period of use the leather of the outside ply remains in comparatively good condition except that the great tensionkon the belt and the narrow width of the inside vply causes extreme frictional contact between the b elt and the drums in a concentrated space whichlnecessitates strong pressure from the belt fork (which is constantly in operation in` this type of spinning machinery) on one.
edge of the outside ply thus causing a quick reduction in the width of said outsideply on one side with the result that the belt is diflicult to reline and repair in a satisfactory manner.
The present invention is designed to provide means whereby the running temperature and fork pressure necessary forl such a belt is greatly reduced by the provision of a `closely pitched series of elongated longitudinal slots cut about the axis of the insldeply,l
` which slots form an air escape between the ls ATENr. carica.' `EDGAR GEOEEREY HNDLEYQOE 'RRADEoR-D., v ENGLAND.
surface of the drum and the belt, andthus reduce the heat generated bythe frictional contact of the belt with the drums and also reduce Vthe rigidity of the inside ply in use and consequently increase the eliiciency and' durability of the belt.
Our invention is shown by way of example in the accompanying drawings, in which- Figure lrshowsa perspective view of they endless cone belt kin position on a pair o'f cone drums,
Figure 2 shows a plan View on an enlarged scale of a portion of the cone belt, and
Figure 3f shows a transverse section through Figure 2.'
In Vthe drawings, A indicates the inside ply made up of soft resilient leather. which in use compresses while passing over the surfaces'of the drums `B and extendsV when` Vpassing Abetween said drums. C indicates the outside ply which is fastened to 'the inside ply A by the rivets vD and is adapted to resist the tension and fork action to which the belt is subjected.
The invention is carried intoeffect by pro- Y viding a kclosely pitched series of elongated longitudinal slots E cut about the central axis of the inside ply, as shown in the drawings. llhese slots extend right through the inside ply, but are not carried into' the outl side ply, with the result that thel air reliefs formedV by the slotsbetween the surface of `the drum andthe belt do not increase the' j liability of the belt to buckle in the centre `owing to the edge pressure resulting from the fork action on "the belt caused by the cone ,v
form of the drum.
These longitudinal slots also reduce .the
rigidity of the inside ply and permit an easier adjustment `of the belt to the varying i il torsional strains to which the belt is subjected in passing from one cone drum to the other and consequently reduce the resistance of the fork action and thuslessen the wear on the edge of the outside ply. j'
