CONVEYING APPARATUS'.

SPECIFICATION forming part of Letters `Patent No. 545,807, dated September 3, 1895. Application letl May 2'?, 1895. Serial No.5501799. (No model.)

To all whom, t rita/y concern.-

Be it known that l, THOMAS SPENCER MIL- LER, a citizen ofthe United States, and a resident of South Orange, in the county ot' Essex and State of New Jersey, have invented eenl tain new and useful Improvements in Conveying Apparatus, of which the following is a specification.

My present invention relates to conveying apparatus, in which hoisting or hauling ropecarriers are fixed upon or \vithrespect to a cable or track. In Letters Pate/nt No. 496,203, granted to me April 25, 1893, a form of such,7 apparatus was shown on Sheet 2 of the drawings of said patent and claimed. In said patent a modification was also shown on Sheet l of the drawings of the patent, but the differences in said modication from said tiret form were not claimed and constitute a distinct invention, which consists in so constructing the carrier that it is as it passes the carriage split in two parts, one part being deflected to ontl side and the other to the other side, and ital'so consists in other features hereinafter pointed out.

In the accompanying drawings, Figure l is a general side view of 'an apparatus containf ing my present invention. Fig. 2 is a sectional plan of a portion of the carriage and the rope carrier,showing the position of the parts as the carriage is approaching the ropecarrier. Fig. 3 is an end View 0f the same. from the left of Fig. 2, bntshowing the carriageand rope-carrier complete. Fig. 4 is a side View of the rope-carrier. Fig. 5 is a cross-section of the same ou the line y 'y of Fig. 4, but in its split position as when passing the carriage and with its construction modified to the extent of having the clamps extending over the cable made in one piece with the hangers instead of in separate pieces, as'iuFig. 4.

A and l5 are the towers,.O is the carriage, D is the fallblock, E is the fall-rope, F is the inward hauling-rope, G is the outward hauling-rope, H is the cable or trackway, I is the drum for the inward and outward haulingropes, J is the drum for the fall-rope, and K are the rope-carriers, all of which are fixed upon the cable H or a stationary rope supplemental thereto with proper spaces between them.

The carrier consists of two hanges adapted in normal position to support. the roller Z centrally `below the main cable H. They are Shown in the drawings as spring-arms, so that each arm acts both as a hanger and spring vmechanism interposed between the hangers to pull them together; but any arrangement which will admit of their separating at the bottom and -will give them a tendency to 'return together,wili answer. Each hanger may consist of the two members yr r', Fig.4, incliuing foro and att from the piece r1, carryin:r the bearing of the roller Z, and clamped to 'the supporting-rope by loops r2 r3, each ot' which is held in clamping position by a crossbol." V5. Upon the bottom of one of these hangers as 71:,is permanently mounted one journal of .the roller Z and the opposite journal m is provided with a bearing at m' on thelower end ot' the hanger 7c', so arranged that when the lower ends ofthe hangers approach each other the tournal m will rest in the bearingm, but` thatY when. the hangers are thrown apart there shalt be no attachment to prevent the-journal separating from its bearing, as shown in Fig. 5. the hanger 7c opposite the roller-bearing, and a guard-piece o is similarly connectcd'with the hanger 7.3. These guard-pieces extend horizontally fore and att, but are bent, as

shown in Fig. 2, so as to deiiectthe lower ends of the hangers 7o andk on either side as the carriage passes. Detlectingsurfaces are placed `upon the carriage to cooperate with the guard-pieces o and o in producing this result. Forvthis purpose l prefer to use the edges oli `the fall-rope sheaves pp', which may be beveied, as shown at p2 293, so that when the guaid-pieoes o o strike these beveled surfaces tne guardpieces'will be deflected, as indicattr'i in dotted lines ot' Fig. 2, so as to carry tree roller Z and its journals on one side of the vertical parts of4 the fall-rope andthe bearineg'm' on the other side thereof. The beveled edges of the sheave pform substatitially deflector-pieces p2 p?, which, in the pre ferred form, as shown7 are a part of the wheel itself, but their being a part of the wheei itself is not necessary. In fact, they may in some cases be omitted entirely, dependence being then placed upon the, deflecting action of the guard-pieces attached to the rope-car A guard-piece o is connected with- IOO rier in conjunction with `some part moving with the carriage, or vice versa. It is possible to omit the guard-pieces from the ropecarrier and depend upon dellecting mechanism on the carriage alone for entering between the hangers 7c 71: and splitting them apart.

In operation when the carriage is at a distance from any particular rope-carrier the rope-carrier will be in the position shown in Iiig. 3, wherein then fall-rope is held in the space bounded by the roller Z below and the hangers 7c and Za on each side, .Vhen, how ever, the carriage comes up to the rope-can rier, so that it becomes necessary for the rope- .carrier to avoid collision with the vertical strands of the falbrope suspending' the fallblock and also with any parts moving with the load-ca rr-iage, the rope-carrier will split apart and a 'av parts inoving'with the carriage and th vertical portions of the fallrope to pass tnA `V`ugh without collision. 'The two parts of the falla'ope carrier, however, are

Iurged to'return to their normal position by mechanism, such as the spring ot' the hangers 7971: in the'form shown, so that as soon as thecarriage has passed the two parts will immediately close together. The hangers 7c llo extendt'ar enough down, so as to bring the roller [substantially below the top of the carriage ,tall-rope she-ave or sheaves p p', so that when the fall-r pe carrier closes up the roller-Z will always be below the fall-rope and the haugers 7a k on each side thereof, preventing its escape from control, the rope 7L, whereby the fall-rope carrier is supported, being, as the carriage passes, above the level of the fallrope and fall-rope sheavc. The rope Il, by whiclhthe allfropecarrlms are supported, enf. gages with the sheaves or wheels a a', which, being mounted upon the carriage above the top level of the fall-rope sheaves p p', insures that the support of the fall-rope carrier as'it passes the carriage will be steadied relatively to the carriage above the fall-rope.

I claiml. In a conveying apparatuain' combination, a loa-d carriage, a fall-rope-carrier, a snpport for said tall-rope.-carrier, and deliecting mechanism whereby the hangers of said fallrope-carrier are split apart as the carriage passes; said fall-ropc-carriez" consisting of hangers extending downward from said support on each side of the fall-rope and a fallrope-rest connected with one of said hangers and normally held near the other hanger, substantially as described.

2. In a conveying apparatus, in combination, a carriage, 'a fall-rope-carrier, a support for said fall-rope-carrier, a fall-rope*sheave Maser mounted upon said carriage, means mounted upon said carriage above said fall-rope-sheave whereby said. carriage engages with said fall rope-carriersLippert, and dellccting mechan ism whereby the hangers of said all-rope-carrier are split apart as the carriage passes; said fall-ropecarrier consisting of hangers extending downward from said support on each sido ofthe fallu-ope below the top le'vel ,ot' said fall-rope-sheave and a fall-i'ope-iest connected to one of said hangers and normally held -near the other,'substantially as described.

3. A fall-rope-carrier consisting of the hangers 7i; 7.3', a loop whereby Ithe saine are adapted to be clamped to a SuppOr'tingrOpe, a roller l connected with one ot' said hangers and deflecting pieces o and o connected with both of said hangers, substantially as described.

e. In a conveying apparatus, in combinan tion, a load-carriage, a all-rope-carrier, a support for said fall-ropecarrier, hangers for said. .falbropeoarrier normally held toward each other by a spring tension, and dellecting mechanism whereby said hangers 'are split apart in antagonism to said spring tension as the carriage passes; said tall-rope-carrier bcing constructed of'hangers extending down ward from said support on each side of the fall-rope and a fall-rope-rest connected with one of said hangers, substantially as de scribed.

5. In a conveying apparatus, the combina.- tion of a cable or t ack, a carriage depending therefrom, a `fall-iope-sli.eave mounted thereon, two hangerssuspended from a pointabore the level ol the tall-rope-sheave extending `downward on each side of the fall-rope, a fallroperest mounted upon one ot' saidhangers below the level of the fall-rope and means whereby said hangers are split apart while the carriage passes, substantially as described.

G. In a conveying apparatus, in combination, the cable or track, a carriage depending therefrom, a fall-rope-sheave mounted thereon, two hangers suspended from a point above the level ol the fall-rope sheave and normally tending to approach each other, a fall-ropeA` rest mounted upon one of said hanger-r, and means whereby said hangers are deiected apart while the carriage passes, substantially as described.
