WILLIAM W. GROW, F TREECE, KANSAS REGISTER MECHANISM.
Application filed August 26,
The present invention relates to registers, and aims to provide a novel and improved mechanism for registering the operations of a mine. hoist or the like.
A further object of theinventionis the provision of a registering mechanism of the kind indicated which has novel provisions for preventing false operation thereof, so astoassure of accurate registrations of the opera,- tions of the hoist.
A still further object is the provision of a novel device or circuit controller for operating or controlling a register and adapted to be operated automatically by-the hoist bucket when. same is dumped.
With the fore oing and other objects in view, which will e apparent as thedescription proceeds, the invention resides in the construction and arrangement of parts, as herein after described and claimed, it being understood that changes can be made within the scope of whatis claimed, without departing from the spirit of the invention.
The invent'on is illustrated in the accompanying drawing, wherein.
Figure lis a diagrammatical view ofthe hoist and registering apparatus.
Fig. 2 is an elevation of the register. i A hoist is illustrated diagrammatically,
' consistin of. a hoist bucket 7 suspended by a cable 8 W ich passes over a pulley 9, for liftingmaterial from a mine, or the like, and the bottom of the bucket 7 has an eye 10 or other element for the engagement of a hook llon' when the bucket 7 is elevated out of themine the hook 11 may be engaged with the eyelO, and when the cable'8 is slackened the bucket will be suspended upside down, as seen in dot and dash lines in Fig.1, for dumping the bucket'at one side of the mine shaft.
Incarrying out the invention there is provided a registerp13, which maybelocated in the oflioe 'or at any other suitable distant point, in'order thatthe' operations of the hoist may beconveniently noted," and said register 13 is controlled by a switch device or circuit controller 14, with an electrical circuit 15 connecting said-device and register;
The switch device 14 includes a substantially horizontal lever .16 fulcrumed to a post 17 secured on a beam'18 supported by or form ing part of the framework of the hoist, and
the upward movement of the lever16 is limited by a stop 19 in which the lever works,
said stop being secured to the beam 18. A
the end of a dumping cable or rope 12,'so that x 1927; Serial No. 215,665.
spring'2O isconfined between the lever 16' and, .beam 18 for raising the lever. A bridle or suspension bar 21 is pivotally connected with the lever 16, and the dump cable 12 is connected to said bar 21. The lever 16 has a longitudinal series of staples or eyes 22]":01'
the connection of the bar 21, for purpose of adjustment to regulate the weight thatis required to depress, the lever16 against the pressure of the spring 20. The bar. 21 may thus be adjusted on the lever 16 according to theweight of the bucket 7 and its contents, so that a predetermined weight is required before the lever 16 is depressed.
The depression of the lever 16 closes the circuit 15 to operate the register 13, and for this I arm 26 to swing same downwardly, the downward movement of said arm being limited by an adjusting screw 30 carried thereby which seats on a stop 31. The arm 26 is thus per 24 is raised, the arms 25 and 26 both being capable of yielding.
'In order to prevent the circuit 15 from be ing closed by the depression of the lever 16, excepting when the bar. 2 1 is swung downmitted to swing upwardly when the contact wardly to vertical position by the suspension 3' therefrom of the bucket-7, an insulator or barrier 32 is normally disposed between said contacts, and is carried bya bracket 33 which is mounted on a rod 34 disposed slidably above the beam 18, said bracketbeing clamped be tween a pair of adjusting nuts 35 threaded on said rod. The rod 34 is connected to a slide 36 which moves on the beam 18 and which has a roller 37 or other means for the contact of the bar or bridle. 21, so that therod 34 is pushed rearwardly when the bar 21 is swung from the full lineto the broken line position as seen in Fig. 1. A coiled compression spring 38 is confined between the post 17 and an adjusting nut39 onthe rod 34, to move said'rod forwardly, thereby moving the insulator 32 between the contacts 23 and 24, and also swinging the bar 21 to the inclined position shown in full lines in Fig. 1. A stop nut 40 is threaded on the rod to contact withthe post 17 and thereby limit the forward movement of said rod.
lVith the parts in positionas shown in Fig. 1, the lever 16 may be depressed, but the insulator 32 will prevent the contact 24 from touching the contact 23, so that the circuit 15 remains open. This will prevent the operation of the register, should the operator or attendant make effort .to operate the register falsely. It is also necessary that the lever 16 be depressed with sutllc'ient force to overcome the spring 20, which is a further check against false operation of the register.
lVhen the bucket 7 is suspended trom the bar 21, said bar will be swung to vertical position, thereby pushing the rod 3-1 rearwardly, and the insulator 32 will be withdrawn from between the contacts 23 and 24, so that the depression of the lever 16 will move the contact Q l against the contact 23, thereby closing the circuit 15. When the weight ot the bucket 7 is released from the bar 21,, the spring 88 restores the insulator 52' and bar 21 to normal position. 4
The register 13 includes the dial wheelsel, 4:2 and 43 for units, tens, and hundreds, and additional wheels may be employed, said wheels being mounted for rotation in a case 4-1 which has openings or windows 45 through which the numerals on said wheels are exposed to indicate the number of operations of the register. As well known in registers, the wheel 42 is rotated one step for each complete revolution of the wheel 41, and the wheel 43 is rotated one step for each complete revolution of the wheel e2. As shown, this is accomplished by lingers 46 on the wheels 4.1 and 42 which contact with annular series of pins l? on the respective wheels 42 and 43.. The wheels have ratchet teeth engaged by spring pawls 48 to preventreverse rotation of said wheels.
A lever 49 istulcrumed, at 50, within the case 454 and its movement is liinited'by adjustable stop screws 51, and said lever carries a pawl 52 to engage the ratchet teeth of the wheel 41, to move said wheel 41 one step for each oscillation of said lever. The lever 49 is connected with armature 53 within the influence of an electromagnet 54: connected in the circuit 15, so that when the circuit is closed and the electromagnet energized, the armature 58 is swung to depress the lever 49, to thereby advance the wheel 41 one step, and when the electromagnet is deenergized, the lever 19 is restored by a spring 55.
In order to prevent the register from being ope ated two or three times in rapid succession,such as migl t be attempted by the opera tor or attendant, means is provided whereby a time interval is necessary between the successive operations of the register. As shown, such means comprises a dash pot including the cylinder 56 in the case M and a piston the air through the valve 58., the inlet 59 havins, a check valve to prevent outflow through said inlet. The valve 58 may be adjusted so as to regulate the time required tor the upward movement of the lever The time in terval may therefore be such to prevent the repeated operation the register excepting when suiticient time has elapsed tor the repeated operation ot the hoist. The dash pot will therefore not interterc with the normal operation of the register by illG successive operations ol' the hoist, but will prevent the register from bein operated more often than the normal operations of the hoist.
Havi-ngthus described the invention, is claim-ed as new is 1. The combination with a hoist bucket and hoisting means therefor, of means attachable to the lower portion of the bucket for suspending it in inverted position, a register, and controlling means for said register operated by said suspending means.
