SPLIT BELT-PULLEY.
To all whom 'it may concern:
Be it known that I, CARL Siarmn N YBERG,
a subject ofthe King of Sweden, and resident of Hasselb'acken, Mellsa, in the lKingdoin of Sweden, have inyented certain new and useful Improvements in Split Belt-Pulleys, of which the following is a specificabeing made to the accompanying drawing.
The present invention'refers to a split belt pulley which'is chiefly characterized by there being arranged around the parts' a band servin as a. ring,lthe ends of which band are united at the inner side of the ring by means'of bolts or some other suitable device, by the tighten-ing of which not only the' parts of the pulley are kept together, and the pulley is fastened on its shaft but by means of which, also, said band or ring may be curved or made convex in cross section. In the accompanying drawing there is shown a form of construction of a. pulley in accordance with this invention.
Figure 1 shows the pulley seen from the side, and Fig. 2 the same seen in plan. Figs. 3 and 4 show in section two forms of the rim of the pulley. j The pulley, which can consist of two or several parts is, in the drawing, shown as Over the rim of the two parts there is arranged a band l, the 'ends 2 and '3 of which are bent inward toward the center of the pulley. and enter into-one of the two openings between the parts of the pulley. The knees 4f of the ends 2 and 3 are so arranged on the band, that the said knees are at a little distance from each halves are in the position relative to each other that they ought to have after being placed on their shaft.
2 and 3 pass one or sevbolts 5, the number being dependent, partly on the breadth of t-he ring and partly on the shape of the rim of the 0n tightening the bolts, the and 3 ought to rest against each other at 6, for which reason the ends at this place are preferably bent over, or a suitable plate or other member is interposed between these ends. Instead of the ends of the band there' can be fastened at the endsof the band suitable angle iron pieces, through which the bolts 5 are drawn.
Speeication of I .etters Patent. Application x'led February 9, 191i.
Serial No. $07,623.
size of ring can be varied by tightening the outermost bolts more or less, and by this action, also, the cross sectional curvature of the ring may be suitably varied.
ln order, on the one hand, to easily center the band on the rim, and, on the other hand, to prevent the band from being pushed` to the side or sliding off the rim, there are arranged on the inner side of the band stamped or pressed elevations 7. which in the form of the rim shown in Figs. and are situated at the sides of said rim, and, in the form shown in Fig. 4, enter into a groove or the like, arranged in the rim. These elevations can, if so desired, be in the form of ridges along the length of the band, or can be replaced by projecting pieces or rods fas# tened to the inner side of the band, which pieces or rods can also be employed to Stillen the band if this be necessary.
It can easily be seen that the section o-f the rim of the pulley parts can have other forms than the V-forni shown in Fig. 3, or the T- form shown in Fig. l.
It is clear that the arrangement described above can be employed with pulleys of metal as well as of wood, and that it is independent of the device at the nave, and this, whether there be used at the nave special bolts for the fastening to the sha-ft or not.
Haring now described my what. l claim as new and desire to Letters Patent is:
pulley comprising sections. each section consisting of a hub ortion, spokes and a rim segment, aflexi- )le band placed loosely around said rim segments and constituting a continuous rim by means of which said sections are held together and secured to a pulley shaft, and means at one point of said band for adjustably connecting the ends of said band together, saidl last namedmcans including extensions of said band turn .d toward the pulley center, the ends of s. id extensions bearing .against each other and having a bolt connection therethrough.
invention, secure by a plurality of pulley ln witness whereof I have hereunto set lVitnesses CARL Tn'. SUNDHOLM, HANS B. OuLssoN.
