MINE AND LIKE SIGNALING APPARATUS Filed Sept. 30; 1951 INVENTOR.
V 4 Jz/mzazm iii-firm the bell or bells to be-sounded seven: times and provided with a spring controlled pawl f arranged to engage the ratchet wheel 6 anchored to the plate d when moved in one "direction but overruns the teeth of said ratchet Wheel 6 when the handle or lever is released and is returned to its zero position by means of its springf A bellcrank lever g is'pivoted at g to theframe a in such position that one of its ends-preferably provided with a. roller g is in the path of theteeth d on the'plate d so that as the latter revolves, eacho'f said teeth causes an angular movement QL E -l' he lever g. The other end of said lever g is provided.withanumber of holes'gi-anyone of which may be connected to the transmitting wire or cable w. A stop orbufi'er a is'provided on the frame ato limit the downward movement-of'the roller end of the lever; g, whichstop or buffer may be faced with a re silient material. As the most common signal in use is one stroke of the bell, a movablestop h is preferably provided to limit the move ment of the rocking lever or handle f neces-' sary to make such a signal. stop 72. may take the form of a pin carriedby a chain or flexible connection and engaging a hole in the frame a so as to project in the path of the-lever r 5 1 In operation, on movingtheyhandle or lever until its head orpointer f agrees with the number or signal to be transmitted, say No; 7 on the dial b, the bell crank lever :gzwill have been moved seven times, thus'causing the indicatorwhic h forms no part ofthis 1nvent1on-near the winding engine to' visibly indicate the signal No. 7. The indicator,
which is preferably used comprisesa'single stroke bell which is. sounded each time the transmitting wire or cable is operated in com bination with a pointer moving over a dial. lettered and numbered to correspond with the dial 6. The hammer ofthe bell is. pro vided with a spring controlled trip leverwhich "engages a pawl to-ioperate a ratchet wheel. The-pointer of thedial is carriedby the ratchet wheel so that the signal is given visibly andaudibly. The pointer-remains to indicate the last signal given until a fresh signal is transmitted, whereupon the pointer flies back to zero before the bell is sounded.
' The compensatingdevice to takeup' the slack oft-hetransmit-ting wire or cable is such that the movement at the operative end of the wire or cable as is greater than that requiredatfits other end to sound the bell,'for instance if the movement required to sound the bell is a stroke of six inches, then the movement of the operative lever is a stroke of nine inches, the difference being taken up by an adjustable spring. One such arrangement of compensating device,".see more particularly the right handside of Fig. 1, comprises a yoked frame 1', the upper end z' bf which is attached to the wire or cable to passing to the bell and/or in The movable.
the rod 2' and act between the sliding plate a? and the fixed plate 2", and the strength of the springs i yandthe movement of-the rod 2' with respect to the frame 6 is adjusted by means of a nut 2' threaded on-the rod i and contacting with the upper surface of the sliding plate 5 of the frame.
I declare-that what I claim and desire to secure by Letters Patent is 'A mine and like signaling apparatus comprising a fixed dial, a series of radial divi-- sions, onefor each signal, on said dial, a rev- .oluble plate carried behlnd sald dial, a handle rotatable on the axis of the dial and plate, a pointer carried by the handle and movable over the division on said dial, a one way clutch forclutching the handle to the plate,
a spring arranged to return the handle to its normal position of rest after operation, movablestops' to limit the movement of the handle, a plurality of teeth or projections onthe plate corresponding tothe pitch ofthedivisions' on the dial, a bell crank lever, the one end of which is successively engaged by said teeth or projections as the plate is rotated, so.
that the lever is moved or oscillated a number oftimes corresponding to the number of divisions over which the pointer on the handle has been moved, a transmitting wire or cable connected to the other end of the bell crank lever for operatinga signaling bell or indicating means and a spring controlled compensating device interposed within the length of the transmitting wire or cable, as set forth.
