' J. D. STORE... DRIVING BELT.
No. 508,153. Patented Nov. 7, 1893.
UNITED STATES PATENT OFFICE.
JAMES D. STORIE, OF OSHAIVA, CANADA.
DRIVING-BELT.
SPECIFICATION forming part of Letters Patent No. 508,153, dated November '7, 1893.
Application filed August 25, 1893- Serial No. (N0 modem To all whom it may concern.-
Be it known that I, JAMES DOUGLAS SToRIE, of the town of Oshawa, in the county of Ontario,-and Province of Ontario, Dominion of Canada, have invented a certain new and useful Improvement in Driving-Belts; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to belts designed for use on smooth faced wheels, or ordinary pulleys; and it has for its main object to increase the efficiency and durability of such belts.
To this main end and object my invention consists in the combination with the usual flat belt of leather, or other analogous belting material, of a metallic chain, or link-belt, which is made somewhat longer than the said fiat belt of leather, or other analogous belting material, and which is arranged'exteriorly of the said belt, but is left free to travel independently thereof; all as will be found hereinafter more fully described, and as will be more particularly pointed out in the claim of this specification. l
Heretofore, a leather belt has been combined with-a drive-chain, the chain having been arranged exteriorly of the said belt; but insuch case, the chain and leather belts were of equal lengths and were fastened together, so that they had to travel, or run, in company at every point through their-length; and the result has been that in the use of such a device the softer and distensible leather band would stretch andbecomebu-ckled, or crimped, and the action of the combined parts has been found to be inefficient and unsatisfactory. I have found that, by combining with a leather, or other analogous belt, a somewhat longer link-belt, or metallic chain, arranged exteriorly of the leather belt; and leaving the two bands free to travel independently of each other, so that the outer metallic belt can travel faster than the inner leather band, the draft-strain will be divided between the two bands; the metallic belt, however, taking all excessive strain that would tend, or operate, to injuriously affect the inner leather band, while the latter, without being subjected to extensive tensile strain, will afford all the adhesive quality necessary to insure the action of the duplex drive-belt under excessive draft- And I propose to provide for use a drive-belt, constructed upon this novel principle of action, which will be more efiicient and cheaper than any heretofore known, or used, to my knowledge.
To enable those skilled in the art to which any improvement relates, to make and use driving-belts, embodying my invention, either in the precise form' herein shown, and described, or in some other I will now proceed to more fully describe my novel construction of endless band, for the transmission of power and motion, referring by letters to the acoompanying drawings which form part of this specification, and in which I have shown my said invention carried out in precisely that form of driving-belt in which I have, so far, successfully practiced it.
In the drawings, Figure l is a side view of a pair of smooth faced Wheels, or ordinary pulleys, banded together, with one of my improved, combined leather-band and endlesschain,dri-ving-belts.- Fig. 2, is a partial view, on an enlarged scale, of the compound, leather and metallic driving-beltseen at Fig. 1'. Fig. 3 is a side view of the drive pulley-seen at the left hand side of Fig. l, and a portion only of the driving belt, but showing the pulley of larger size. 4
In the several figures the same parts will be found always designated by the same letter of reference.
E and E are two ordinary smooth faced pulleys (mounted on suitable shafts) that one marked E being represented as the-driver and the one marked E as the driven; while A is an endless band, or belt, of leather, arranged in connection with the pulleys in about the usual manner, and B is a metallic chain, or endless, link-belt, that is somewhat longer than the belt A, and encompasses the leatherband A, and, as shown, is arranged centrally thereof, in the direction of the width of the latter; all as clearly shown in the drawings.
The faces of the pulleys E and E are, of course (as usual), of slightly greater circumference at the middle portion than at the edges of the wheels peripheries'(for the wellknown purpose of preventing the leather drive-beltAfrom running off either of the -strain, without any slip on the pulley faces wheels) and, therefore, it is necessary to provide some means of preventing the narrower link-beltfor" chain B, from runningoff' the leather band; which latter, of course, assumes (wholly, or partially) the convex form, in cross section, peculiar to the pulley-faces.
In the case shown, the series of leather cross-bars O, which are riveted near their ends (as shown at D) to the belt A, and which loosely confine the chain B laterally; servers hold the chain in place, and compel it to travel in a path about coincident with the middle (widthwise) of "the hand A, 'biit some this? device or expedient may, of 'course',b'e use'd to serve the purposes of these retaining devices.
t w e en e th hs le s ha n B. s mat t ylhh er tha he, eathe e t which,as usual,;is banded tauton l fi pl lyr nd i wi 'bet t etoqs ha Said hai B is perfectly free to move (longitndinally) independently of the beltA, througheutjts direction, that th link-belt isrendere d cqp t ble of taking the draft strain, while, at the same time, all stretch, or elongatiomof the leather belt, fro n one, or another,cause, is al;
lowed to form slack at the vicinity of that; min of e ce hh td e t Wh r t ech h Slack; nd us vo l crimping, uck i sand' p ht ihs o he l a rhe tt heret e hain, exerts a draft strain on it.
"Although the chain Bis made materially longer than the leather band A, the discrepancy between the two will be reduced some during continued use, by the stretching of the 7 band A; but never to such an extent that the chain will not be longerthan theleather band; 1
.d sl s e s hle for to the diiference in length between the two belts is due the above described action that' is'peculiar to my improved compound driving belt.
In the operation of a driving belt made according to my invention, the narrower and chapeiybut "inextensible and more durable chain B, sustains the greater part of, orall the excessive draft-strain, to which the said driving-belt "is subjected; while the wider and more expensive; but easily stretched and less durab e a her b nd. erforms h y the fttiict'ion of'the adhesive" "device of the compound drive-belt; "without, however, being stretched and soon worn out, or rendered unserviceable- Hence Where. h surtouhtl ci cumst nces I'QFLQ QUQ eeesserytor, for the ak o qqn mal SfihPtllliQ'lli tense attemre atively narrewl e her .belt, such. 242 elt lfiQQbllltllilQHWlhh heme; "0, 311 at: e sed. t e r tenth me .e. 9. 9.mor.w9rk f -r ransmit mor ,pqyretrwhilel at, e same tim i l las L eh ehtet s that o e iginal. with?) tht h leather elto er width t CQIUTSQ, the .PhQRQlIiiQHM?fi h hfi t hee f ,sttee thef th eethenandllhhhsl shown; heir elative, en ths; hs Qthert e: i s the n M19?
