In the drawings, A represents the cable, which may be constructed of any suitable ma terial and in any preferred way, and can be mounted on proper supports between the terminalsas, for instance, in the manner shown in my previous patent, No. 269,525, September 26, 1882. I

The terminal wheel is represented, generally, by the letter B, itbeing secured to a shaft, D, mounted in a suitable framing.

, The wheel B may be provided with any preferred means for gripping the cable; or, so far as the other features of this case are concerned, this wheel may be a plain one-that is, may be used without supplemental gripping devices.

I have shown devices which are adapted to grip the plain portions of the cable, and also adapted to yield when the clips which carry the buckets come in contact with them,whereby I insure that said clips and the cable shall not be thrown out of proper place.

' The gripping devices shown consist of a series of levers and leversupport of the character of that shown detached in Fig. 5. In said figure, B represents the shank of a lever, and b the toe or upwardly-projecting part. The lever is supported in a frame, 13 b by means of a pivot or cushion, as at b". To permit the adjustment of the toe of the lever, I combine with it a set-screw, V, which passes through. a threaded sleeve, b, and bears against the stationary part b it being locked in place by a nut, 12*. Preferably each of these levers projects through an aperture in the up wardly-rising flange A on the terminal wheel, as will be seen by examining Figs. 1 and 2. The toes project outwardly just above theline of the cable, and there is a tapering space be low the outer end of each into which the cable crowds, and therefore the friction upon the cable is increased.

In Figs. 1 and 2 all of the details of these Fig. 19 is a section gripping devices are not shown, there being merely sufficient in said figures to illustrate the general relations of the parts. The shaft carries a wheel, D, below the cable-wheel B, this wheel D being toothed or recessed in such manner as to be adapted to be engaged with the bail of the bucket when the latter is passing around the terminal wheel, the bucket being carried by a pendant, G, joined to a clip, C, which is fastened to the cable, the bucket bail or pendant being held properly relatively to the wheel D by a guideor camtrack, D", which partially surrounds the shaft D, and the tipping of the bucket for emptying it being effected by a second guide or camtrack, D adapted to engage withthe side of the bucket or an arm projecting downwardly therefrom. However, these parts last above described may be of the character shown in my aforesaid Patent No. 269,525, and therefore need not be dwelt upon here.

In the aforesaid Patent No. 269,525 devices were shown in combination with the terminal wheel whereby the bucket could be emptied when the cable was situated in a substantially horizontal plane, the axis of the terminal wheel being in a corresponding positionthat is to say, on a vertical line; but a cable tramway of this character may be available under another set of conditions prevalent in regions wherethese tramways are often necessary-that is to say, upon the sides of hills" or mountains.

A construction and arrangement of parts will be described whereby the cable may be allowed to lie in a plane more or less inclined .to the horizon while it passes around the terminal wheel, the said wheel lying in a parallel plane.

The wheel, together with its shaft, and the parts combined therewith are supported upon any suitable frame-work adapted to hold the said parts at an inclination corresponding to the plane in which it is desired that the cable shall move.

In the drawings I have shown a frame-work, but wish it to be understood that I do not limit myself to the details of its construction therein shown, having selected one which at present I prefer, but which may be more or less varied as circumstances require.

The parts of the frame shown consist of one or more girts similar to that above referred to at E, one or more longitudinal sills, E E, uprights E E, (see Fig. 1 and dotted lines, Fig.

2,) near the terminal wheel, the position of.

the upright E being indicated by dotted lines in Fig. 2, uprights E 'E at a suitable distance therefrom, and top beams, E E joining, re spectively, the uprights E E on one side and E E on the other. The main frame-work thus constructed has attached to it a guide-rail, e, (see Figs. 1, 2, and 3,) extending from a short upright, E near the terminal wheel to another short. upright, E near the upright E this guide-rail 6 being so related to the track or guide D that together they shall form a continuous guide. Another guide-rail, e, (seeFig. 3,) is secured to the main frame, it being fastened to the uprights E E and having, preferably, a metal face-plate, e, and above this a third guide or track is provided, it consisting of a metal bar or plate, 6, secured to the outer face of a bar, 6 fastened to the frame. 1

e 6 represent guiding sheaves or pulleys, upon which the cable can rest as it moves to' ward and from the terminal wheel, and of these any suitable number may be employed.

WVhen the means above described are to be employed for supporting the terminal wheel at an inclination to the horizon, and for guiding properly the cable and the buckets to and fro, it (said frame-work) can be supported by a supplemental one below, consisting of any suitable number of sills, as at e, and uprights 6 6 (see Figs. 1 and 3,) together with whatever braces and girts are required.

.Upon the main frame, still referring to Figs. 1 and 2, there is mounted a traveling carriage, which, also, in its details, may be of various forms, the one shown having two downwardlyextending bars, F F, joined by cross-bars F F the latter being at or nearly at the top, and a third cross-bar at or nearly at the bottom, concealed behind, 6, Fig. 1. This carriage is held in place upon the guide or track e by means of anti-friction wheels or rollers F.

there being two or more engaging with the 7 upper edge or face of the track a, and two or more with the lower, whereby the whole carriage is held properlyin position. The carriage is also provided with two or more grooved sheaves or rollers, F upon which the cable can rest, so that there shall be no friction exerted upon the carriage by said cable.

f represents a rocking bar, mounted suitably, for instance, in hearings in the upper crossbar, F and in the lower cross-bar. This rocking bar'f has a laterally-projecting arm, f, which, when the parts are in the position shown in Figs. 1 and 2, lies somewhat above the cable and across the same in the path of the clips 0 It has also an arm, f in the same plane (transversely of the barf) as is the bar 6', or its metal facing-piece e the end of this arm f when the parts are in the position shown in Fig. 1, bearing against the said facing-piece 0, so as to prevent the bar f from rocking; but when the parts have moved tothe other end of their throw the bar 0 or its. facing-piece e" no longer engages with the arm f and therefore the latter does not prevent the bar f from rocking or yielding to a force exerted upon the arm f at the top.

f is a-finger attached to the rocking barf, (see Figs. 1 and 15,) and which, when the parts are in the position shown in Fig. 1, lies ioo in the path of the pendants or of the carriers sition shownin Fig. 1, and after the carriage has been drawn'down to the terminal wheel in the manner to be described this weight returns it to the position shown in the saidFig. 1. The weight may be arranged in the simplest way-that is to say,' the end of the rope may be tied to the carriage, the rope passing over the pulley G down to the weight; or, to make it more effective in a well-known manner, the end of the rope may be secured to the frame, as shown at g, and may be attached to the weight by means of a block and pulley.

The operation of the devices above described is as follows: Then a bucket approaches, the pendant which carries it is in a vertical position, although the cable is inclined, (see' Fig. 1, dotted lines.) the pendant being preferably united to the clip,which is secured to the cable by ahinge-joint. The clip first passes over the sheave or pulley e when the latter is employed, then moves forwardover the supportlug-sheaves F until the pendant O strikes the army and the clip 0 strikes the upper arm, f, the latter action taking place shortly after the pendant strikes the arm f When these two contacts have been effected, the pendant will be thrust out of the vertical position into one substantially perpendicular to the plane of the cable, (shown in dotted lines, Fig. 1,) in

order that the bucket and the pendant may be properly received upon the terminal wheel and upon the rag or toothed wheel D. The onward movement of the cable after the contacts have been effected causes the carriage to move forward toward the terminal wheel, the escape of the clip from the armf and of the pendant from the arm f 3 being prevented by reason of the bar f bearing against the part 6 which, as said above, holds the rocking barf and the arms atff rigidly relatively to the cable; but when the parts have been advanced sufficiently far the arm f escapes from the part c at the end c Fig. 1, and therefore the rocking barf is allowed to turn to yield to the pressure exerted by the clip and the pendant. The parts are so relatedin size and position that this escape shall be effected at the instant the clip (1 reaches the point 0 (see Fig. 2,) where the rectilineal part of the cable is tangential to the wheel. As the pendant O has been up to this time held substantially perpendicular to the plane of the cable A, it or the bail which it carries engages with the rag or sprocket wheel D at a point corresponding to the point C of contact of the clip with the terminal wheel. After the clip and pendant have been released from the carriage the weight G operates to draw thelatter back into the position shown in Fig. 1, readyto act in a similar manner relative to the next bucket or carrier. A stop, as at G may be used, or any other suitable for the purpose of arresting the carriage.

In order to prevent any back movement or rebounding of the pendant after it has come in contact with the arm f, a stop, H, (see ward motion.

Figs. 1 and 16,) is employed, which is arranged to yield to the pendant as the latter moves inward; but after-it has passed the stop H moves outward across its path to prevent its back- As shown, the stop H is formed upon or carried by the end of a flat spring, H, against which the pendant presses as it moves in, (see dotted lines, Fig. 16,) and which effects the outward movement of the stop after the pendant passes.

I have also shown in the drawings the means which I have devised whereby a bucket may be emptied or not at certain points, so that a separation between the loads dumped by the various buckets may be permanently preserved. I

. It is well known that it is desirable to keep the ore produced by one miner separate from that produced by another. I accomplish this separation, and preserve 'it by employing different bins or receptacles and combining therewith devices by means of which certain of the buckets shall be dumped into one bin or receptacle, and another or others shall be dumped into another receptacle.

Referring to Fig. 7, I represents a camguide secured to the frame, and which is adapted to engage with the side of the bucket, or with an arm projecting therefrom to a greater or less distance, so as to effect a dumping of the bucket and its contents into a bin or receptacle. Of these dumping cams or tracks as many may be employed as are the separate masses which it is desired to obtain. The dumpers on the one hand, and the buckets or carriers or the pins or projections carried by the latter on the other hand, are so related to each other that some of the carriers shall engage with one cam or dumper and pass all others, while another set of carriers shall engage with another dumper and pass all others, and so on to any extent desired.

The necessary variations of the dumpers relative to each other or of the buckets or pins carried thereby can be readily effected, and to those acquainted with the art various methods will suggest themselves for varying the parts relative to each other to accomplish these ends.

In Figs. 17 and 18 a cam is shown as being movable, the cam being supported in standards I 1 having bolts 2' in slots 2', though Ido not wish to be limited to the devices shown.

In Fig. 18 the dotted line indicates the normal vertical plane of the pin (1* on bucket O that is to say, the line on which said pin would move were it not throwh out by the du n per.

The dumpingcam may be supported in any suitable way to accomplish the various ends aimed at. It is shown as mounted upon a frame-piece, but in this respect there is wide range for variation.

In the construction shown each cam engages with certain of the buckets or with the pins carried thereby, the latter being of sufficient ICU length to engage therewith, and each of the other cams engages with another set of buckets, the engaging portions being related to each other differently from those of the other sets by means of a difference in position or length, &c.

The frame and carriage in Fig. 7 may be the same as in Figs. 1 and 2 and need not be described.

I will now describe the means which I employ to effect the loading of the continuallytraveling buckets.

Referring to Figs. 8, 9, 10, 11, and 12, J J represent the longitudinal sills of a frame provided with suitable cross-girts, J J it having also uprights J J at one end and J J at the other, and having at the top a longitudinal beam, J on one side and a platform, J Upon the general framework thus described there are mounted two or more sheaves or pulleys, K K, upon which the cable rests as it moves over the frame.

j represents a track-bar,preferably of metal, secured to the sill or beam J corresponding to that at 6 already set forth.

9' is a track or cam secured to the top of the platform J it consisting of a metal bar supported in any suitable way upon standards j, it having at one end an inclined part, 9'

Upon the track-bar j there is mounted a traveling carriage having the following parts:

L L are downwardly-projecting bars, joined by cross-bars L L L, the last two being the one at the top and the one at the bottom.

L L are rollers fitting upon the top of the track j, and L L rollers fitting upon the under side.

M M are sheaves or rollers, carried by the carriage-frame, and adapted to have the cable pass over them, they preventing frictional engagement between the cable and the carriage.

m is a rocking bar mounted in a plate, in, at the top and in a corresponding plate at the bottom. This rocking bar m has an arm, m lying in the path of the cable-clips, an arm,

of, lying in the path of the pendants, which support the buckets or carriers, and an arm, m, which, when the parts are in the position shown in Fig. 10, bears against the platej.

The parts last above described-to wit, those indicated by L L L L L L L m m m are analogous in structure and operation to the corresponding parts above described in the construction shown in Figs. 1 and 2.

There is a loop-like frame, Figs. 10 and 12, which surrounds the path of the buckets carried by the cable, and shown as having the parts N N N N N; but I do not wish to be limited to the exact construction shown, as it may be varied more or less. I prefer to have the part N extend somewhat backward from the bar on, and the part N project downwardly to a point below the path of the buckets. The part N lies below and across said path, and is united to the part N which rises up on the outside of said path. At N there is an ble. O. which carriesa roller, 0, adapted to ride upon offset, or the frame is projected inwardly to or somewhat over the upper or outer edge of the bucket.

N represents a plate rising from the part N. It carries a bin or hopper, O, of the form be delivered into the bucket carried by the ca- The bin or hopper is closed by a slide, To this slide there is attached a bar, 0

the track j j is a bar or rod rising from the plate N it being fastened to a cross-piece, M carried by an upwardly-rising support, M", secured to the carriage-frame L L L. The bar 0 1oose ly engages with the bar P, so that it can slide up and down relatively to the latter. (See Fig. 10.) An upward movement of the bar 0 and of the slide 0 is caused by the cam or guide 3' j" when the carriage moves forward.

In order to assist in holding the loop-like frame N N N N N 4 steady, I mount a roller or friction-wheel, T, upon the under face of the part N By preference this wheel or roller T lies horizontally, as shown in Figs. 10 and 12, and travels between guide-rails t t, mounted upon the frame-work, these guiderails being provided with metallic facingstrips 11, when desired.

Q, is a guide-piece having an outwardlycurved end, as shown at 9 It can be adjusted toward and from the bin or hopper by means of screws or other regulating devices, as shown at q q, Figs. 10 and 12.

Qis an opposite guide-piece,having a curved end, q", this curved end, together with the curved end of the other guide, being so arranged as to insure that the pendant of the buckets shall move in the proper path.

R is a stop analogous to the stop above described, it, in this case, however, consisting of a pivoted bar bent to have an angular portion, 1', in combination with a spring, T. It can yield to an incoming pendant, but after the latter has passed the part r said part swings across the path of the pendant and prevents the latter from moving backward.

The operation'of the devices constructed and arranged as above described is as follows, it being supposed that the bin or hopper O is loaded with material and situated in the position shown in Fig. '10: Then as the empty bucket approaches, its clip first passes over the sheave K and then over one or more of the sheaves M until it strikes the arm m, the pendant of the bucket at the same time striking the arm in". As soon as these contacts are effected the carriage is drawn forward by the cable, together with the loop like frame N N N N N t N 5 and the bin or hopper carried by the latter. As the carriage and hopper move forward the slide 0 is forced upward bymeans of the cam j j*, and after that the material is permitted to drop into the bucket, the latter being held so that it cannot move away from S, which preferably passes over a the bin or hopper, as will be readily seen by examining the drawings. After the transfer of the material has been effected the carriage reaches the end of the bar j, whereupon the arm m* can swing outwardly, and, as a result, the arms m m are thrust out of the paths of the cable and of the pendant, and the latter pass on disengaged from the carriage. Then the weight S operates to draw the carriage back to its initial position, the weight being connected with the carriage by means of the cord pulley, s, and is connected to an arm, 8*.

Having thus fully described the specific devices shown, in order that a clear understanding may be had of one form of mechanism embodying my invention, I will say that I do not limit myself to all the details shown and described, for it will be apparent to any one skilled in the art to which the invention appertains that many of the parts may be more or less varied without departing from the spirit of the several parts of the invention. Thus it is not necessary that the devices for unloading the carrier shall be of exactly the form shown, and, in fact, the reciprocating carriage may be used to steady the carriers and hold them in proper place under modified circumstances.

I in the claims appearing below describe the bucket and its support asacarrier, and itwill be seen that the particular features in detail of this do not necessarily enter into the invention, as carriers of various sorts may be used, if adapted to intermittingly engage with a carriage which can support them or hold them in a given position relatively to the cable.

Again, it may be remarked that as regards the holding of the carrier properly in a given position the essential feature consists in providing a stop which shall be impinged upon by some portion of the carrier or its support, and which will be adapted to hold the carrier in the desired position, and adapted, under some circumstances, to throw it into a position out of the normal. Thus, the partf acts as a stop temporarily; not that it stops the motion of the cable or the onward movement of the carrier, but it insures that the carrier shall be in the desired position, and in this respect this portion of the device operates similarly in the construction shown in Figs. 1 and 2 for unloading, and in the construction for loading shown in Figs. 8, 9, 10, 11, and 12.

\Vhen it is desired to unloadacarrier where the cable is inclined, the part acting as a stop may be used to throw the carrier or carriersupport out of the normal position occupied when freely suspended; but, under other circumstances, it need not vary the position of the carrier-as, for instance, in Figs. 7, 8, 9, 10, &c.

In the claims below I refer to the means for unloading the carrier. I have shown several forms of devices for effecting this object, one form having the toothed wheel on the terminal wheel-shaft, the circular track D, and the cam-track D another form (shown in Fig. 7) having a stationary canrtrack, I, and another form, Figs. 17 and 18, having an adjustable cam-track; and prior to the date of my patent other means have been known for unloading cable-carriers; and therefore I wish it to be understood that in the combina tions set forth in the following claims I mean to include not only the specific devices that I have shown, but also those which are the equivalents thereof.

Again, it will be noticed thatI have shown and described (in order to have the apparatus clearly understood) but one form of carrier or receptacle 0, it being simple in construction, and I have alluded to this in the claims below as a carrier or receptacle, 0; but it will be understood that any equivalent carrying device may be substituted therefor so long as the other features incident to this part of the invention are preserved. for it is well-known at this day that not only may cable-carriers be provided with one pendant, but also that they may be suspended by two, three, four, &c.,and with carriers of such species, loading and unloading devices having the characteristics of mine may be readily combined. So, too, it is well known atthis day that in many respects tramways in which the cable is stationary and the carrier is movable relatively thereto are similar to tramways of the specific character which I have shown; and therefore I shall also apply to such a stationary cable and movable carrier my devices for loading and unloading and my means for holding the carrier properly relatively to the loading and unloading devices.

I do not in this application claim any of the features relating to the gripping devices which I have shown, or those relating to the clip or clamp for securing the carriers to the cable, as I have made these the subject-matter of other applications for patent; nor do I claim any of the combinations claimed in my application No. 138,584, filed July 23, 1884, or 104,917, filed August 27, 1883.
