UNITED STATES PATENT OFFICE.'
ISAAC LINDSLEY AND BRADFORD BORDEN, OF PAWT UGKET, R. I.
IMPROVEMENT IN TOP-ROLL COVERINGS FOR DRAWING-FRAMES.
Specification forming part of Letters Patent No. [52,133, dated June 16, 1874; application filed J une 5, 1874.
.To all whom it may concern:
Be it known that we, ISAAC LrNDsLEY and BRADFORD BORDEN, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain Improvements in Covering Top Rolls, of which the following is a specification:
Our said improvements relate to covering top rolls of drawing-frames, Speeders, spinning and other similar machinery, with alternate and intermingled layers of elastic and non-elastic gelatinous substances suitably prepared.
The accompanying drawing is hereby made a part of this specification.
Figure 1 is a view of a top roll covered with the materials, and in the manner substantially as hereinafter set forth. Fig.2 is a transverse sectional view of thecovered boss of said roll on the line X X of Fig. l.
The diagonal lines in the center of Fig. 2 show a transverse section ot' the boss of said roll, and the concentric superficial lines indicate the successive layers of the elastic and non-elastic gelatinous substances aforesaid.
The great defect in leather-covered rolls, or rolls covered with the various materials and substances hitherto used for this purpose, is the inevitable tendency of the covering vto stretch in the line of the circumference of the roll, and then to become loosened from or on the boss of the rolls, or to gradually work or` gather into a crease or fold, either one or all of which occurrences is, or are, equally ruinous to the sliver of cotton. Vith the exception of leather, all the substances and materials hitherto'used for covering top rolls have possessed these defects in a marked degree. Yet, although leather possesses these defects in a lesser degree, it still retains them to such an extent as to be an objectionable feature in its use, and also to be the chief cause of its wearing out. To remedy these defects, and still to retain a certain diametrical elasticity to the covering of the roll, is the object of this invention. To accomplish this We cover said rolls with alternate layers of elastic and nonelastic gelatinous substances suitably prepared and applied. The elastic layers are of glue, rendered elastic by the internlixture therewith of any of the common and welltic layers is essential to the confining and binding of the soft and elastic layers.
The use and application of these elastic and non-elastic layers, for the purposes mentioned, are or may be substantially as follows: The iirst layer may be ofthe elastic substance, and is applied directly to the boss of the roll, or to a cloth or similar article previously fastened to said boss, by any of the known means.
This rst layer, like all the succeeding ones, is
to be applied thin, and partially or nearly dried, the next succeeding layer being added while the first is sufciently moist to secure a perfect union of both. rlhis second layer is to be of the nominally pure glue, applied in a liquid state after the first layer has nearly or partially dried, as aforesaid. This second layer having partially or nearly dried, a third layer of the elastic glue is similarly applied; and so on, alternately, until the requisite number of layers or thickness of covering is obtained. We have applied these several layers with an ordinary brush, as it were painting the successive layers on to the boss of the roll. But it is intended that the order of building up these layers, or the Way of applying them to the boss of the roll, may be varied as circumstances may require.
The office of the elastic layers is to give the roll the necessary diametric elasticity, while the office of the non-elastic layers is to give the covering strength, tenacity, and iirmness. These layers of nominally pure glue will yield diametrically just enough to secure the benefit of the elastic layers, but from their nature it will be impossible to stretch them circumferentially. By this combination of the diverse characteristics of the different layers7 we secure, in a simple and effective Way, the requisite diametric elasticity, and the circumferential tenacity and firmness. Any wear or abrasion of this covering, or of any part thereof, may be easily and quickly repaired Within the inill or factory, and at tritling eX- pense. The method of repair would be, mutatis amata-mm, substantially the saine as the original building up of the stratiform eoverin 0'.
NVe are aware that top rolls or roller coverin gs have heretofore been produced that have, to a certain extent, been elastic in the interior and non-elastic on the surface, and that characteristic, viewed simply as a result, We do not claim as a new feature in top rolls or roller coverings; but We are not aware that gelatinous substances, prepared and applied substantially as aforesaid, have ever been used for the purpose, and in the manner described.
Vhat, therefore, We do claim as new, and desire to secure by Letters Patent, is-
A top-roller covering, built up or composed of thin, intermingled, and alternate layers of elastic and non-elastic gelatinous substances, substantially as described. v
ISAAC LINDSLEY.
