THOMAS SPENCER MILLER, OF SOUTH ORANGE, NEW JERSEY...

HOIS'IING AND CONVEYING APPARATUS.

To all whom it may concern:

Be it known that I, THOMAS SPENCER MILLER, a citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Hoisting and Conveying Apparatus, of which the following is a specification.

My invention relates to hoisting and conveying apparatus and especially to a mechanism particularly adapted for use in conjunction with cableways.

In the accompanying drawings I have shown my invention embodied in the form which is at present preferred by me, but it will beunderstood that various modifications and changes may be made in the structure without departing from the spirit of my invention and without exceeding the scope of my several claims.

In my co-pending application Serial No. 434,068 I have shown a form of cableway in which the hoisting motor is mounted on the load carriage, and the conveying motor is located on the base of a tower supporting the cableway. In the present instance I have devised a novel arrangement wherein one motor is used, preferably mounted upon the load carriage, not only for hoisting, but also for conveying. Such a construction is particularly well adapted for the transportation of light loads and I obtain a simple, compact and economical arrangement for the purpose for which it is devised. It will be further noted that I suspend an electric motor from a single wheel running on the main cable, the motor being preferably located close to such cable. The armature shaft of the motor is also preferably extended from both ends of such motor and at each end of the shaft I mount a friction pinion, one friction pinion being geared to drive a single gear reduction to operate the conveying drum, the latter being provided with a curved face adapted to drive a rope Specification of Letters Patent.

rapidly thereabout, the ends of such rope being fixed at the terminals of the trackway. The pinion at the opposite end of the shaft drives, through the medium of a double set of gears, a drum for the purpose of hoisting the load. This latter, or hoist drum, is supported by means of a truck formed in the present instance, of a pair of wheels rolling upon the cableway, this construction insuring that the weight of the load will be supported directly by the cable.

My invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the several claims.

In the accompanying drawings, Figure 1 is a side view of the carriage and its connected parts, such View also illustrating a portion of the main cable, and a portion of the conveying and the hoisting ropes; Fig. 2 is a top plan view, a portion of the truck or carriage being broken away to more clearly show the hoisting drum; Fig. 3 is an end view showing the hoist drum; Fig. 4 is a'face or end view showing the conveying drum, the preferred location of the operators station, and the lever mechanism for controlling the conveying andhoisting mechanism. Fig. 5 is a detailed sectional view through one of the clutches for connecting the power shaft to the winding and hoisting drums.

Referring now to the accompanying drawings in detail, 5' designates the main .cable which may be stretched between any two terminals or supports and secured or mounted in any preferred and well known manner. Traversing this cable is the truck or wheel 6 from which'is suspended the motor M. Connected to the motor is the frame 7 having the sides 8 thereof extending above the cableway and pivoted to the truck 9 provided with the traction wheels 10, 10, said truck being especially adapted to support thehoisting drum 11 and the load carried by the hoisting rope 12. It will be noted that I have provided the truck with a plurality of Wheels, as the main load to be carried by the cableway is supported directly at this point.

13 designates the operators station or seat, located upon the carriage above the cable 5, and preferably directly over the conveying drum 14, the latter being carried by brackets 15 secured to the frame of the motor M.

16 and 17 designate braces or struts for suitably supporting the operators station or seat.

The conveying rope is indicated at 18, said rope having its ends Orterminals suitably secured at the points of support of the main cable, and it will be noted that said conveying rope is wrapped several times about the conveying drum, so that when power is applied through the motor M, the carriage with its connected devices, may be propelled along the main cable.

It will of course be understood that power is imparted to the hoisting drum for the purpose of hoisting the load and to the conveying drum for the purpose of propelling the load through the agency of the motor M, and this is accomplished as follows: The numeral 19 indicates the armature shaft of the motor, the ends of'said shaft projecting out and beyond the sides of the motor frame, as clearly shown in Fig. 2. Upon one end of the shaft is loosely mounted the pinion 2O meshing with the gear 21 secured to the shaft 22, the opposite end of said shaft carrying a small pinion 23, which latter is in mesh with the gear 24E at the end of the hoisting drum shaft 25. jThe opposite end of the armature shaft is also provided with a loose pinion 26 meshing directly with the gear 27, keyed to the end of the conveying drum shaft 28. Both the hoisting drum and the conveying drum are keyed directly to their respective shafts. It is my purpose to drive both the hoisting .drum and the conveying drum from the armature shaft and to place the power transmitting mechanism interposed between said drums and shaft into and out of driving engagement with the motor, at desired times. In the present instance to accomplish this, I preferably proceed as follows; For instance, to drive the hoisting drum I provide, at the end of the armature shaft carrying the pinion 20 the friction plates 29 and 30, keyed or splined to the shaft and adapted to be shifted longitudinally of such shaftto place the pinion 20 into and out of operative engagement with the shaft. This shifting of the friction "plates is accomplished by the thrust mechanism 31 ac tuated by the hand lever 32 conveniently located relative to the operators station. Similarly, to place the conveying drum into and out of driving engagement with the arm erator.

of the shaft, I provide such shaft with the friction plates 33, 34:, keyed or splined to the end of the shaft carrying the loose pinion 26, said plates being shifted into and out of engagement with such pinion through the medium of the thrust mechanism 35 actuated by the lever 36, under the control of the op- It will of course be observed that as one or the other of the levers is moved to thrust the plates in toward the side of the motor, the inside friction plates 30 and 34, respectively, are fast upon the armature shaft, that is, are free to turn therewith, but have no movement longitudinally thereof, while the outer plates 29 and 33 are capable of longitudinal movement upon the shaft when actuated by their respective levers, so that when these plates 29 and 33 are shifted inward toward the motor frame by the thrust mechanism, the pinions 20 and 26 will be frictionally held by the pressure of the two plates, and, therefore, power may be readily transmitted.

The specific arrangement of the gears 20 and 26 and their clutching means is immaterial, as other means (not shown) may be employed for accomplishing the same result. I have shown, however, in Fig. 5 the specific arrangement of these parts in order that their arrangement and operation may be clearly understood. Inthis figure, which illustrates the gear for operating the propelling rope drum, the disk is shown arranged to abut a shoulder 19 on the shaft 19, the shoulder serving to limit the move ment of said disk along the shaft, the disk being keyed to the shaft by'a key 3 1*. The outer disk 33 is feathered to the shaft, as at 33 to slide longitudinally thereof in both directions, being moved against the gear, as above described, by means of the thrust mechanism 3536. The gear 26 is slidably mounted upon the shaft and has interposed between its hub and said shaft a bushing 26 The same description applies to the gear 20 and the parts associated therewith.

While I have herein described my preferred form of clutch mechanism for the armature shaft, I wish it to be understood that I do not confine myself to the specific construction herein set forth, as other forms of clutch mechanism, either friction or otherwise, may be employed.

For holding the load in suspension when conveying such load, I provide the brake wheel 37, keyed to the hoisting drum shaft 25, such brake wheel being provided with a suitable and well known form of band brake, and similarly for holding the carriage in any position along the cableway I provide the brake wheel 38 secured to the conveying drum shaft 28, said wheel being also provided with any suitable and well known form of hand brake. V

It will be noted that with the construction herein shown the weight of the load is not placed directly upon the motor, but is properly and suitably supported from the cableway, and, further, that with the motor located between the hoisting drum and the conveying drum and adapted to operate both drums, either independently or simultaneously, I provide an exceedingly simple, compact and durable construction of apparatus and one especially adapted for rope operation in the transportation of comparatively light loads.

I believe myself to be the first to devise a construction wherein is embraced a double friction pinion upon the motor shaft to drive in turn independently or simultaneously a hoisting drum and a conveying drum. It will further be noted that the operator is preferably located above the carriage where he is enabled to observe at all times the load and the machinery hoisting and conveying the same.

Having thus described my invention, what I claim is 1. The combination of a hoisting mechanism, a conveying mechanism, a motor shaft for operating both of said mechanisms, and independent means on said shaft for placing said motor shaft into and outv of driving engagement with the hoisting mechanism and the conveying mechanism.
