ERNEST POULLAIN AND CHARLES POULIJAIN, OF PARIS, FRANCE.
DRIVING-BELT.
SPECIFICATION forming part of Letters Patent No. 235,018, dated November 30, 1880.
' Application filed June 5, 1879. Patented in France February 3, 1879.
lo all whom it may concern Be it known that we, ERNEST PoULLAIN and CHARLES POULLAIN, of Paris, France, have invented certain new and useful Improvements in Driving-Belts for Machinery, of which the following is a full, clear, and ex, act description, reference being had to the annexed drawings.
Our invention consists, first, in a drivingbelt for machineryformed with a series of continuous longitudinal grooves in one or both of its sides; second, in a driving-belt for machinery composed of two leather bands having their opposing faces formed with a series of continuons longitudinal grooves, and fittedtogether, all as hereinafter more fully described.
In the accompanying drawings, Figures 1, 2, 3, and 4, Sheet 1, represent sections ot' grooved belts or bands. The section Fig. 1 has one face smooth and the other with grooves very rounded at the top, the section Fig. 2 smooth on one side and the other with angular grooves or channels. Fig. 3 has double grooves, producing an undulated section, and Fig. 4 is a section of a double belt having its two'outside edges smooth. In Sheet 2, Figs. 5 and6 are an elevation and plan of as1nooth` faced pulley with a belt or band with externalA channeling or grooving. Figs. 7 and 8 represent, in elevation and horizontal section,"
theapplication ot' an internally-grooved belt to a pulley with cast grooves.
As will be seen by` Figs. 1, 2, 3, 4, what is meant by grooved belts or bands of leather, india-rubber` or gatta-percha, india-rubber tissues, and s0` forth, is belts of these mate-k rials on .which are formed, as hereinafter .de-
. scribed, ribs extending from end to end of the of whielnp, is grooved. We placev the leather on this plate on the side where the grooves are required, and press thereon with the smooth movable plate p', leaving theleather r 1",- one=` of which, y, is grooved. 'lheleather vis passed between these two rollers. ,The surface ofthe leather" to be grooved turns toward the grooved roller r. Pressure is then exercised on the axis of the smooth roller 1" by means of a screw or otherwise, and by putting the machine in motion, either mechanically or by hand, the lea-ther is gently passed and repassed between the rollers, if so required, and is withdrawn with the groovesim pressed there- Third. The third machine, Figs. 11 and 12, Sheet 1, comprises as the essential organs a grooved plate, p, and above it the smooth roller r, producing by any suitable means a more or less active pressure. The roller?` and the platep (on which the leather is applied on the side to be grooved) work together slowly, the leather under pressure of the roller takes the impression of the grooves of the plate by passing it through once or twice, as required.
The speed ot' the two rollers r r', Figs. 10 and 11, and plate pandroller r, Figs. 12 and 13, may be identical or vary more or less, according as it may be desired to avoid lengthening the leather or to stretch it within prescribed limits.
In making double or triple bands or belts the faces are grooved which should meet, and the leathers a b are united at the grooved sides or faces. (See Fig. 4.) The grooves are disposed soas to gear one with the other, the grooves being coated with size or glue, guttapercha, or some equivalent adhesive matter .when itis desired to unite them closely by means of such substance, and aided by axed pressure.' The bands or belts may also be united by thread, screws, rivets, eyelets,- and so on.
A belt orrband constructed according to our invention possesses many advantages, among IOC are not liable to stretch farther. by the grooving process has its pores closed, and is thickened and strengthened at. the ribbedparts, and the belt, being grooved longitudinally, will not twist-ou the pulleys. If desired, the pulleys or wheels which these belts pass over may be corrugated, so that the ribs of the pulley t into the grooves of abelt when the grooved face of a belt is applied to such pulley.
Having thus described our invention, we claim- 1. A driving-belt formaehinery, formed with The leather i a, series of continuous longitudinal grooves in one obotlx of its sides, as described.
2. A driving=belt for machinery, composed ot two leather bands having their opposing faces formed with n series of continuous longitudinalgrooves, and tted together, its herein described.
