RECORDING DEVICE FOR HOISTS.

SPECIFICATION forming partof Letters Patent No. 677,286, dated June 25, 1901.

Application filed February 18, 1901. Serial No. 47,792. (No model.)

To ctZZ Lu/"@0111, it may concern:

Be it known that T, FRANK MOM. STAN- TON, of Houghton, in the county of Houghton and State of Michigan, have invented a new, useful, and Improved Recording Device for Hoists, of which the foll'owingis a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding reference-numerals in the different figures indicate like parts.

My invention relates to recording devices for hoists and lifts of various kinds, but is more especially designed for those used in mines, in which hoisting is done from one or more levels. It is especially valuable in such cases to know the number of trips made by the car, cage, skip, or bucket, together with the respective levels from which hoisting has been done, as well as the speed of the car, the number and duration of stops, and when and where the same have occurred. The indication of the number of trips made by the hoist has heretofore been accomplished by means of some crude and primitive device-such, for example, as placing pegs in holes formed in a board under the control of the engineer or I sents a hoisting-engine of any approved patin other equally uncertain and objectionable ways.

The object of my invention is to overcome the objections incident to such methods by providing a simple and accurate recording mechanism so constructed that it will not only record the number of trips made by the car, cage, skip, or bucket and'that automatically, but also the time consumed in making said trips, respectively, the levels from which the same were made, the speed of the moving element to be timed, and the time of rest at the beginning or end of the respective trips, as well as at any intermediate level or levels, so that a complete and accurate history of each days work may be preserved for reference by those interested.

To this end my invention consists in the combination of elements hereinafter more particularly described, and definitely pointed out inthe claims.

'In the drawings, Figure 1 is a plan view of an engine and a portion of a hoisting-drum, showing the manner in which my improved recording device isconnected therewith. Fig.

Fig. 12 is an enlarged sectional view in detail of the scaleprinting mechanism, said view being taken upon the line 12 12, Fig. 3, viewed in the direction of the arrow there shown. Fig. 13 is a like viewtaken upon the line 13 13, Fig. 2, viewed in the direction of the arrow there shown; and Figs. 14, 15, and 16 are diagram matic views showing different records made by said recording mechanism.

Referring to the drawings, 1, Fig. 1, repretern, on the shaft 2 of which is mounted a cone-shaped drum 3, over whichis trained the usual hoisting-rope. Arranged parallel to the engine-shaft 2 is a small shaft 4:, (also shown in Figs. 2, 3, and 5,) which shaft is mounted in suitable bearings and is provided with a sprocket-wheel 5, connected, by means of a sprocket-chain 6, with a similar sprocketwheel upon the shaft 2. The shaft 4 constitutes the prime motor element of my improved recording device, and while it is shown in the drawings as being connected directly with the shaft of the winding-drum it is obvious -that it may be connected with whatever primary element of which it is desired to record the speed, the application being varied to conform to the varying construction of different kinds of hoists or lifts. The shaft 4: is

projected through a suitable casing 7, within 65 attachedthereto, said cord being trained beneath a pulley 66 and, having its opposite end attached at 67, Fig. 4, to the case 7. From the pulley 66 is suspended, by means of a suitable hanger, a weight 68. A gear 69 upon the shaft 63 meshes into a pinion 70 upon a shaft 71, Figs. 3 and 4, which is supported in bearings in the uprights 9 and 10. The shaft 71 is extended through the upright 9 and has keyed upon the projecting end thereof a gear 72, which meshes into a pinion 73 upon a shaft 7 4.

Keyed to the shaft 74 is a friction-drum 75, which is in engagement with a shoe 76, jointedly attached to the short end of a lever-arm 77, pivoted at 78 to a bracket79, which is rigidly attached to the upright 9. A screwthreaded bolt 7 9 ispassed through a vertical bore in said bracket and is provided with a spring 80, interposed betweenthe long arm of said lever and a washer upon said bolt, to cause the shoe to press against said frictiondrum. The tension of said spring may be adjusted by means of a suitable nut 81. The purpose of the friction-drum and tensionbrake described is to enable the speed of the shaft 74: to be controlled against the action of the weight 68, by which said shaft is actuated, it being desirable to render the speed of said shaft constant in order to properly feed the paper web, as hereinafter specified. Secured to the shaft 74, so as to revolve therewith, is a feed-roll 82, Figs. 3 and 5. v Parallel to the axis of the shaft 74. is a similar shaft 83, having a friction-roll 84tmounted thereon, said shaft being provided with suitable bearings, in which allowance is made for slight lateral play. Springs 85 85 (shown in Fig. 3 and indicated in dotted lines in Fig. 5) serve to draw one shaft toward the other and to cause the feed-rolls82 84: to press against each other with a spring-pressure.

A paper-roll 86 is secured to a shaft 87, one end of which has a bearing in the upright 8, while the other end has its bearing in a sleeve on the end of the shaft 13 upon which the drum 14: is supported, as shown in Fig. 2.

In a vertical plane between the shafts 7 1 and 87 and above said shafts is located a shaft 88, having a roller 89 thereon, the periphery of which is slightly below and in oper ative proximity to the stylus 58, said roller forming a platen for the paper-web upon which the registration is intended to be made.

A roll 90 is mounted upon a shaft 91, attached to which is a cone or friction gear 92, adapted to engage with a counterpart gear 93 upon a shaft 94:, which is journaled in the uprights 9 and 10. Pulleys 95 96, Fig. 3, are keyed to the shafts 74 94:, respectively, and connected by means of a belt 97, whereby the shaft 94 may be driven from the shaft 74, while the shaft 91 may in turn be driven through the action of the friction-gears 92 93. A coiled spring 98 serves to maintain said gears in frictional contact.

The paper-web 99 is unwound from the roll 86, trained over the platen-roller 89, thence downwardly between the feeding-rolls 84 82, beneath the latter, and thence upwardly over the roller 90, as shown.

Although not absolutely essential, it is highly important to provide a suitable scale upon the margin of the paper-web in order that comparisons may be readily made, not only as an aid in the reading of the record, but to enable said record to be made more compact. This may be accomplished as follows: A bracket or hanger 100, Figs. 2, 3, 5, 12, and 13, is rigidly attached to the upright 8 and is provided with depending arms 101 101, in the lower ends of which is journaled the shaft mantle of a printing wheel or disk 102, having figures upon its periphery for marking the hours, between which figures are divisions. preferably representing fiveminute spaces. The arms 101 are provided with vertical slots 103, Figs. 12 and 13, for the reception of the axle of said wheel, which provides for a limited vertical movement of the latter. A lever 104., pivoted to a stud 105,

attached to the frame, is provided with bi-' furcated arms 106 106, between which said printing-wheel is interposed, and are provided with bores to receive the axle of said wheel. A coiled spring 107 connects the free arms of said lever with a threaded bolt 108, extending through a bore in an arm 109, rigidly attached to said hanger. An adjusting-nut 110 enables the tension of the spring to be regulated. An electromagnet 111 is located beneath the lever, as shown, and is electrically connected with a battery 112 and a suitable circuit maker and breaker controlled by the clock 62, which circuit-maker is adapted to makeand break the circuit at intervals of five minutes. A ratchet-wheel 113 is attached to the shaft of the printing-wheel and is adaptedto be engaged by a pawl 114. when the circuit is broken with the magnet 111, and the wheel is lifted by the lever-arms 106 through the recoil of the spring 107, this action serving to shift the numbers consecutively. -An ink-1 011115 is provided for distributing ink upon the printing-wheel.

I have suggested the closing of the batterycircuit for the control of the printing-wheel at intervals of five minutes; but it is obvious that it should be done whenever an impression is desired, which is a matter of predetermination.

Having thus described in detail the con struction of my improved device, I will now explain its operation.

Assuming the paper-web to be adjusted upon the rolls in the manner described and the weights 27 and 68 raised, the starting of the engine causes the rotation of the windingdrum 3, the motion of the shaft of which is transmitted through the chain 6 and shaft 4, together with the gears 11 and 12, to the shaft 13, thereby actuating the miniature windingdrum 14, the motion of which is transmitted to the cylindrical drum 16 through the cord for accomplishing these results. The stylus employed may consist of a pencil or pen, and the paper may be of any well-known quality suitable therefor; but ,I prefer to use a metallic stylus and to employ what is known as metallic paper, which is a paper having a prepared surface adapted to receive and retain a mark from such an instrument.

At the close of each day the paper-web marked during that day may be removed and dated and filed for future reference, thereby preserving a complete history of the number of trips made by a given car, the number, place, and duration of the several stops, and the speed of the car. The advantages of such a record are obvious to all concerned.

My improved registering device may be applied to all hoists, lifts,or elevators, whether the usual winding-drum be employed or not. For example, in the form of hoist'known as the hydraulic lift it would only be necessary to cause the stylus-carrier to move in some predetermined ratio to the speed of the ram.

When the main winding-drum is cylindrical instead of conical, as shown in the drawings, it is obvious that the stylus-carriage may be actuated directly therefrom and that the drum 16 may be dispensed with. I
