WlRE-lROPE TRAMWAY.

SPECIFICATION forming part of Letters Patent No. 505,397, dated September 19, 1893.

Application filed March 20, 1893.

To all whom it may concern.-

Be it known that I, CHRISTOPHER T. FIN- LAYSON, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Wire-Rope Tramways; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in wire rope tramway systems of the class having two ropes, one stationary rope forming the supporting track along which the buckets move, and the other the traction or hauling rope, to which the buckets are made fast.

My present invention embraces several salient features, namely, a clip made fast to the traction rope, mechanism for automatically gripping the bucket upon and releasing it from this clip, a carriage located at each terminal, or at any intermediate point for automatically and gradually starting each bucket which has been stopped for loading or unloading purposes, and means for automatically dumping the buckets. These are the main or central features which, taken in connection with'those details of lesser importance, constitute a new, complete and thoroughly practicable tramway system.

Hence myinvention consists of the features, arrangements and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is a top or plan view of the loading terminal, showing one bucket in position. Fig. 2 is a side elevation of the same, showing two buckets in place. Fig. 3 is an end view, the frame-work being partly broken away, while parts of the gripping mechanism are shown in section. Fig.

the frame-work being shown partly in section.

Fig. 6 is a fragmentary top view of the construction shown at the right in Fig. 5. is a fragmentary perspective view of the car- Fig. 7

riage, and mechanism for automatically and gradually starting the bucket. Fig. 8 is an enlarged fragmentary view in perspective of the automatic gripping mechanism carried by the bucket. Fig. 9 is an end view of the clip carried by the traction rope, a fragment of the gripping mechanism being shown in verticalsection. Fig. 10 is a side view of the crescent shaped oscillating arm, shown in two positions and in connection with the traction rope, clip and carriage frame. Figs. 11 and'12 illustrate two of the positions which the clip may assume.

Similar reference characters indicating corresponding parts or elements of the mechanism in the several views, let the numeral 5 designate the stationary rope anchored in a frame-work of suitable construction located at the terminals of the line. The traction rope 6 is endless and supported at the line terminals on wheels 7 mounted on and made fast to shafts 8 journaled in the frame-work. The necessary power for imparting motion to the hauling rope may be applied to these shafts in any suitable manner and from any desired source.

Each bucket 9 is pivoted between a pair of arms 10 which are united at the top, and intermediately connected and braced by two

cross-bars

12 and 13. These arms 10 constitute the bucket pendant, to the top of which is centrally pivoted a bar 1i carrying two pivoted sheaves 15, forming a trolley which engages the stationary rope, except at the terminals, where said rope is substituted by curved metal tracks 16 to which the trolley passes as it leaves the supporting rope. The two

cross-bars

12 and 13 of the bucket pendant, are connected by an upright bar 17 which carries a guide sheave 18 at its lower extremity. This guide sheave engages the lower edge of another metal track 19 at the terminals and maintains the trolley securely in place upon the upper track in rounding the curves at these points. Upon the upright bar 17 is supported the vertically movable slide 20, the points of attachment being above and below the bar 18, the slide being provided with apertured projections or sleeves 2O at those points, through which the bar 17 passes. The cross-bar 13 is slotted to receive two dogs 21 and 22 which are pivoted to the bar at their outer extremities as shown at 23 and 24, while their inner extremities carry pins 25 and 26 which enter

slots

27 and 28 respectively formed in the sides of slide 20. The upper portion of slot 27 is narrow, while it is enlarged below. WVhen the pin 25 is in the narrow part of this slot, the dog is locked from movement since this part of the slot is only large enough to receive the pin; while the pin is in the lower or enlarged part of the slot, the dog maybe moved outward or in the direction of the slots engagement, by pressure upon its edge 21, the opposite edge being engaged by a leaf spring 21 supported upon the bar 13. Slot 28 is of uniform width but its lower'part is deflected outwardly as shown at 28 When pin 26 is in the upper portion of slot 28, the dog 22 is locked from movement since the slot is only large enough to receive the pin. When, however, the pin passes into the lower or outwardly deflected part of the slot, the dog has a positive outward movement. Bar 13 is provided with

stationary jaws

29 and 30 located respectively above and below the dogs 21 and 22. As shown in the drawings, these jaws are formed integral with the bar and are slightly recessed as shown at 31 and 32. These recesses indicate the position of the neck of the clip when the bucket is locked on the traction rope. This clip is composed of two clasps 33 which grasp the traction rope 6 and are riveted in slots formed in the arms or shouldered projections 3et of the forked body 35 of the clip. The clasps are loosely pivoted to the body part to allow the traction rope a certain upward and downward movement required in passing over the supports located between the terminals. These intermediate supports are not shown in the drawings as nothing is claimed thereon. The outer or free extremity of the clip is enlarged, forming a head 36 which is connected with the body part by a neck or reduced part 37. This head 36 is fashioned to enter the socket 38 formed by the upper and lower

stationary jaws

29 and 30 and the movable dogs 21 and 22 which control the openings at the ends of the jaws. The head of the clipis ofcircularshapeand fitslooselyin the socketto allow perfect freedom of movement. This is necessary sincethe bucket will always hang plumb,or in a line approximately perpendicular to the plane of the horizon whatever may be the inclination of the traction rope; and asthis inclination is continually changing, the necessity for this movement of the head of the clip in the socket of the gripping mechanism, will be readily understood. The recesses 31 and 32 in the

jaws

29 and 30 allow the neck of the clip to enter as the height of the traction rope varies with reference to the position of the stationary rope. These movements of the clip are illus trated in Figs. 11 and 12.

From the description heretofore given of the construction of the slide 20 and its action on the movable dogs, it will be understood that when the pins 25 and 26 of the dogs 21 and 22, are both in the upper part of their

respective slots

27 and 28, the dogs will both be locked and the clip of the traction rope cannot escape from the socket 38 in either direction. Hence if the tramway is in operation the bucket is carried along by the rope 6.

It will be readily understood that tramway systems of this character must be constructed with reference to stopping for loading and unloading, while the traction rope is in motion. Provision must also be made for starting these buckets after each act of loading or unloading, and while the hauling rope is in motion. The buckets are usually loaded at one terminal and unloaded at the other terminalof the line. The drawings illustrate these stopping points or stations as located at the line terminals, though it is evident that it is practicable to have these stations at intermediate points. The loading station or terminal is illustrated in Fig. 2. At each of these stations, provision is made for raising and lowering the slide 20 automatically for the purpose of allowing the clip of the traction rope to enter the socket 38 for the purpose of picking up a bucket, or to escape fromsaid socket when it is desired to release or drop a bucket. This automatic slide-controlling mechanism consists of a stationary pair of

guide rods

39 and 40 which are supported upon the depending extremities of two arch-bars 41, which bars are made fast to the terminal framework at their opposite extremities. These arch-bars pass upward and over the track 16,

leaving ample space above said track to allow the buckets to pass, while they extend downward a suiiicient distance to support the

rods

39 and 40 in the path of a pin 42 made fast to slide 20 and projecting outwardly therefrom. Assuming that the traction rope is traveling in the direction indicated by the arrows in Fig. 2, as a bucket is carried around, the pin 42 passes between the

guide rods

39 and 40 which are farthest apart at this point of entrance. As soon as the pin enters the mouth of the Way formed by these rods, it begins to move upwardly, being guided by the upward inclination of rod 40. This upward movement continues until the pin 26 of the dog 22 passes into the lower part 28 of slot 28. This movement of the pin 26 carries the dog outward until its inner edge 22 lies in the same plane with the inner surface of the cross-bar 13 in which the dog is pivoted. This action of the dog opens the door, so to speak, of socket 38. As there is now nothing to retain the clip in place within the socket, it will pass out leaving the bucket at rest, and about in the position of the. one shown farther to the right in Fig.2. The bucket at the left, which I will term the first bucket,is loaded and ready to start on its route. As it is not desirable, for obvious reasons thatthe bucket should start or begin its movement with the same speed as the traction rope, provision is made whereby'the starting of the bucket is accomplished by a movement gradually accelerated, until the speed of the traction rope is attained.

The mechanism employed for gradually starting the bucket will now be described,

special reference being made to Figs. 2, 7, and

10. Between the metal tracks 16 and 19 of the terminals,l place a carriage, the frame of which is composed of the upper and lower longitudinal bars 43 and 44, and vertical

end connecting bars

45 and 46. This rectangular frame-work is provided at each of its four corners with a small sheave wheel or pulley 47. The peripheries of the pulleys are grooved to engage the metal tracks. The two upper pulleys engage the lower edge of the track 16, while the lower ones engage the upper edge of the lower track 19, the edges of the pulleys being grooved to a sufficient depth to retain the carriage securelyin place. To the central portion of the carriage frame, are attached two angle plates 48 and 49 forming a longitudinal guideway for the traction rope, and through which the body of the clip passes. Projecting into this way through a slot 49 formed in the lower angle plate, is a curved or crescent shaped arm 50 having its lower extremity pivoted on the track 19. The curved edge of the arm is adapted to engage a lug or projection 51 made fast to the carriage frame, while the upper extremity of the arm is normally supported in the guide way composed of the angle plates, by a projection 50 which rests upon the lower plate. This upper ex tremity of the crescent-shaped arm lies in the path of the clip as the latter is passing through the angle-plate guideway. When the bucket is in the position of rest at either terminal,it is locked on the carriage by a spring catch 52, which engages a pin or projection 17 made fast to the vertical bar 17 of the bucket frame. Hence as the clip is passing through the guideway of the carriage after it leaves the second bucket or that shown at the right in Fig. 2, it will engage the upper extremity of the arm 50 and move the carriage forward. This initial movement, however, is very slow, since the lug 51 engages the arm 50 near the pivoted point of the latter, where the arc of oscillation is small as compared with the are described by its outer extremity where it moves, of course, at the same rate of speed as the traction rope, since it is engaged by the clip. As the movement of the carriage continues, the point on arm 50 which engages the lug 51, recedes from the pivoted point of the arm; hence the speed of the carriage increases from the moment ofstarting until the outer extremity'of arm 50 engages the carriageas shown in Fig. 10. The speed of the carriage and consequently of the bucket, is now the same as that of the traction rope. The arm 50 has therefore performed its function and is now in such a position that the clip passes overit and enline.

ters socket 38 of the bucket. It must be ob served that at the time the clip leaves the arm 50, the pin 42 of the first bucket, shown 7 in. Fig. 2, occupies part A of the guideway formed by

rods

39 and 40, having left partB of the highest part of the way. The slide 20 has then moved downward sufliciently to lock the dog 22. The dog 21, however, is still free to move outwardly, which is necessary in order that the clip may enter the socket. This position of the sliding frame with reference to the pins 25 and 26 of the dogs is illustrated in Fig. 8. It will be observed from a careful inspection of thisfigure that pin 26 has entered the upper part of slot 28, thus moving the dog 22 to the locking position, whereby the clip is retained in the slot, while pin 25 of dog 21 is still in the enlarged part of slot 27. Hence as dog 21 is engaged by the clip, it moves outward, allowing the head of the clip to enter socket 38. After leaving arm 50 and entering the socket 38 as before stated, the carriage continues to move with the first bucket since the bucket is still fast thereon, while the second bucket is also moved by the carriage which is provided with a spring catch 53, which engages the pin 17. This movement of the carriage, and both buckets, continues until the second bucket or that at the right in Fig. 2 has reached the position of the first bucket or that shown at the left of the same figure, when an arm 52 of the spring catch engages a depending pin 54 forming a stop, and draws the arm inward sufiiciently to release the carriage from the first bucket, when the carriage is withdrawn to its original position by a weight55 suspended from a rope 56 which is connected with the carriage and passes over pulleys 57 and 58 on the frame. When stop 54 is reached, the pin 42 of the slide 20 has passed out of the guideway formed by

rods

39 and 40, and the slide has dropped to its normal position, locking both the dogs 21 and 22 and maintaining the head of the clip securely in place within the socket 38, when the bucket is ready to leave one terminal and pass out upon the main It will be observed that when the car riage returns under the influence of the weight, the second bucket remains stationary and the spring catch of the carriage engages the pin 17 of this bucket just as the carriage reaches its backward limit of moveinent, thus locking the same upon the'carriage in the same manner as the first bucket.

I will now assume that the loaded bucket has sition in close proximity to a longitudinal bar 59 of the dumping mechanism. This bar is made fast to the upper extremities of two arms 60 whose lower extremities are pivoted to two other arms 61. These last named arms are pivoted to the lower extremities of the depending stationary bars 62 made fast to one of the stationary bars 63 of the terminal frame. Arms 60 are supported in suitable operative relation by two arms 64 normally inclined and respectively pivoted to the arms 60 at points about midway between their extremities. The connection between the two pairs of

arms

64 and 60 is formed by a horizontal rod 65 carrying a clasp 66 centrally located thereon. Arms 64 are made fast at their upper extremities to a rod 67, whose extremities are pivoted in the upright stationary arms 68 supported upon a bar 69 of the frame-work. To an eye formed on the clasp 66 is attached one extremity of a rope 70 which passes over a vertical pulley 71 and en-- gages a horizontal pulley 72, both attached to the side of the terminal frame opposite from the dumping mechanism just described, the

opposite extremity of the rope being secured to a sliding plate 73, supported upon two stationary rods 74 attached to the frame, one above the other, as shown at the right in Fig. 5. The plate 73 is provided with an arm 73 which projects into the path of the pin 17 secured to the pendant frame supporting the bucket proper, and hereinbefore described. Now, assuming that the bucket is at rest and in the position shown at the left in Fig. 5, as soon as the moving bucket next in front reaches the plate 73 on the opposite side of the frame, the pin 17 a engages said plate and moves it along on its supporting rods. As the sliding plate is thus actuated, the rope 7 O is of course carried along therewith and the dumping mechanism actuated as indicated by dotted lines at the left in Fig. 5. As bar 59 moves upward it engages the pin 9 of the bucket and tips the latter sufficiently to dump its contents. As soon as this occurs the plate 73 is guided inward by its supporting rods, which are deflected sufficiently to carry the plate out of the path of the pin 17*. This deflection of the rods is shown at 74 in Fig. 6. The plate being thus released from its engaging pin, it moves backward to its normal position under the influence of the gravity of the parts with which the rope 70 is connected. It will thus be seen that each bucket in its turn is automatically dumped by the one immediately preceding it, while each bucketis automatically started from its position of rest as soon as the one next in the rear reaches the carriage, the mechanism being so arranged at the dumping station, that each bucket is dumped before it is started, and at the loading station that each bucket is filled before it is started on its course toward the one or the other terminal as the case may be.

The loading of the buckets may be accomplished in any suitable manner most convenient. The material may be shoveled directly thereinto or it may be discharged from a hopper, or any other source, according to the circumstances or necessities of the case. 0
