SPECIPICATIONiOrming part of Letters Patent No. 366,472, dated J uly 12, 1887.
A l n-canon filed March a, res-r.
To all whom it may concern.-
Be it known that I, MICHAEL GARLAND, of Bay City, in the. county of' Bay and State of Michigan, have invented a new and useful Sprocket Wheel and Cable;. and I do hereby and exact description thereof, reference being bad to the accompanying drawings, making part of thisapplication. 1
Previous to my invention a great variety of contrivances for thetransmission of power and motion and involving the use of some sort of wheels or pulleys having combined with them some sort of drive-belt have been used,divisibleinto two general types-viz.,that
' class in which the engagement betweentlie or belt peripheries of the wheels and the endless band has been by frictional contact only, and
that kind in which a positive interlocking device has served to engage the wheels with the endless band or chain belt.
My invention relates to th at typcofiirausenit.
ters in which the endlessw-tra'veling band or I belt efl'ects .aepesitive engagement with the wheels over or partially around which it' passes; and it consists, essentially, in the corn biuation,with wheelshaving their peripheries circuinferentially grooved, and having the re.-
.dial fiangesmt either side of the circumferential groove formed with teeth or sprockets, of a wire orother rope or' cable adapted to run in saidgroove,-- and provided with devices (made i'astthercon) adapted to engage positively with the depressions or-spaces between the teeth or sprockets of ,the wheels flanges,
- all as will be hereinafter more fully explained,
and as will be more particularly pointed out d explicitly defined in the claim 9f this specification. I 1
. my invention To enable those skilled inthe art to which relates to understand and practice the. same, I will now proceed to more fully describe it, referring by letters to the acco'nre 4 which forrnlpart of this" which I have shown rny invention carried out-in those forms in which specification, and in 'I have so far successfully practiced it, and
which arclabout the best formsnow'known to In the drawings l igure l-is a side v ew or elevation of a pair of wheels and a l-endless Serial No. 229,513. (No model.)
-ble-run drive-belt with attachments adapted to the purposes of a conveyor-machine. Fig. 5 is a cross-sectional view of the same taken at the line (not Fig. 4.. :Fig. 6 is a detail cross-section at the line 3/ y of Fig. 1. Fig. 7 is a detailcross-section at the line 2 z of Fig. 3. Fig. 8 shows a form of cable device adapted to carry an elevator-bucket.
ence.
In Fig. 1, A and A represent two wheels or pnlleys mounted upon suitable being" banded together or belted by a wire rope or cable,.A, upon which are arranged and secured at equal distances apart of transversely-arranged bars or devices, A, of a peculiar construction, and for a purpose to be presently explained. v
A'and A are duplicates, so that a description of the structure of one, which I will now giv'e, will answer forvboth.
- The wheel A, as will be clearly seen by reference to Figsl and 2, is nade in the form of a simple rope wheel or sheave, riphery circumferentially grooved for the accommodation of the wire cable or rope A but having the radially-arranged flauges,bctween cut out, so as to form two series of teeth or sprockets, M, the said teeth of each flange being' arranged exactly in line (axially of the wheel) with those of the other flange. .other words, what would otherwise be thetwo radial ,fia'nges of an ordinary peripherallytoothed disks or sprocket-wheels,
illustrated.
drive rope or'band' belted on them, all according l assthaving its pewhich lies the peripheral groove, notched or grooved rope-wheel are made to constitute two as clearly view (on a smaller scale) of a duplex or dou= In the several figures the same part will found designated by the sm le lcttcrof refershafts, A and ICO The transverselyarranged bars A",bcfore mentioned, are made, "preferably, each in two that in passing around or over the wheels the said teeth.
they will match or correspond with the pitch of the sprockets or teeth of said wheels, so as to run in perfect gear or'engagement with the spaces between the roots of said sprockets,all as clearly illustrated at Fig. 1.
By preference the duplicate clamp-like devices A have their semi-cylindrical recesses provided with semi-cylindrical bushings, of some suitably soft metal or other material, for the purpose of efiecting a perfectly-reliable union (by the enforcement together of its parts by the action of the screw-bolts B) between said devices A and the wire or other rope or cable A Those surfaces or portions of the device Al which are arranged to run in mesh or in engagement with the sprocket-wheels formed by cutting the peripheral flanges of the sheaves into teeth A, as shown, are shaped so as to match" with the contour of the spaces between This conformation of the device A with the toothed flanges of the wheels is clearly shown at Fig. 1.
Now, it will be understood, of course, that in a power and motion transmitting contrivance composed, as shown in Fig. 1, of a pair of wheels having their peripheries grooved to seat a row or cable A and also havin the radial flanges formed into sprocket-wheels with teeth A with which the devices A (secured to the rope) engage, as shown, a positive interlock or engagement is effected between the said wheels and the said drive rope or band,'while at the same time the band proper is composed of a simple cable or rope, cylindrical in cross;section, and the peripheries of the wheels provide'simplc grooved bearing-faces for the reception and retention laterally of the driverope, and it will be seen that in such a contrivance a greater or less number of the engaging devices A may be employed to run in mesh with the -aprocketed flanges of the rope-wheel.
Of course the distance between the engaging devices A of the cable may be varied by loosening, slightly shifting, and retightening the parts of said devices whenever, by reason of a'iry stretching of the cable or rope,thepredetermined or original spaces between said engaging devices may be found to vary to any extent from the true pitch of the sprocketcd flanges of the rope-wheels.
The conformation or contour of the teeth A, and consequently of the spaces between means of which they might beeitherpermanently or adjustably secured to the rope A", may be adopted in place of those I have shown in the drawings without departing from the nafare of .my invention. When desirable, the
rope-grooves of the wheels may be lined with vulcanized rubber."
In case it may be desirable or expedient, the tranversely-arranged engaging devices of the rope or cable may be either so differently constructed from those seen at A, or may be so supplemented with other devices, as. to render the traveling cable and its attachments capable of performing not only the transmission of motion and power from one wheel and shaft to another, but also performing any of the usual functions or or belts.
At Fig. 2 I have shown the rope or cable A provided with several forms of transverselyarranged and securely-clamped devices that are adapted not only to engage with the toothed flanges-"of the rope-wheel's there shown, but also perform, respectively, the usual functions or oifices necessary to conveyermachines of different species. For instance, at-A I have shown a'rope attachment or device designed to perform the function'of grabbing and hauling a log, after the usual fashion in log-haulup machines, while at A I have shown a device similar to the usual scraper or flight used in conveyingmachines for moving sawdust, coal, clay, &c. The device shown atA is another form of a more engaging device for engagement with the sprocket-teeth of the wheels, while at Af is another form of device -for the same purpose.
Of course in the application of my invention to the various forms of conveyer or carrier machines -such as coal and sawdust conveying contrivanccs, log haulers, &c.the necessary and peculiarly-constructed flights or devices for such purposes, securely'attached in the proper manner to the wire cable or rope A, may be interspersed with devices-such as seen at Afor engagementonly with the teeth of the wheels which either drive the cable or are driven by it.
At Fig. 8, P is a bucket for carrying flour, grain, &c.
It will be readily understood that the various applications of flights and log-hauling and other attachments for different kinds of conveying-machines, or for cable drive-chain purposes, may be almost endless within the scope of my invention.
purposes of conveyer chains 7 In lieu of a single drive rope or cable, A
adapted to run in engagement with a single pair of wheels, and provided with some sort of-transversely-arra nged deviceswhichengage V .with the teeth A thereof,a duplex ordoublerun driving and carrier contrivance may be made, afterthe fashion illustrated at Figs. 4
and 5, by the use,as there shown, of two separate ropes .or cables, each running over a separate set of sheaves or wheels, and transversely-arranged devices-such as seen at A or A"-'-securel y clamped at each of their ends to one of the cables and adapted to engage with the toothed radial flanges of wheels'somewhat similar to those seen at Figs. 1 and 2. If it be thought desirable or expedient in'the construction of e such a double-run or, duplex drive mechanism and carrier mechanism, the wheels in such eontrivance may be made with only one peripheral flange to each wheel, suit-1 ably toothed to engage with all of. the devices A or A" near one end only of each.
Of course it will be understood, without further description here, that in either the use of a single run or double run of cables, such as shown and described, provided with suitable attachments for positive engagement with the toothed flanges of the peripherally grooved wheels, almost any and every sort of known flight or carrier attachment may be employed of power and mot-ion, or for both transmitting power and motion and performing any of the 3 5 known ofiieesof com eying-machines or carrier-ehains, is
, The combination, with a rope or cable provided with a series of transversely-arranged sprocketdike or engaging devices which proo ject laterally of said rope, of wheels each of which has a peripheral groove for. the accommodationof said rope, and theflanges of which are toothed or notched to effect a positive ongagement with the laterally-projecting pol- .5
tions of said'cngaging devices, all in substantially the manner hereinhcfore set forth.
In witness whereof I have hereunto set my hand this 24th day of February, 1887.
