ALARM-COUNTER FOR PRlNTlNG-PRESSES, 8a3.

SPECIFICATION forming part of Letters Patent No. 354,024, dated December '7, 1886.

Application tiled Muy Q1, 1884.

To all whom t mar/y concern:

Be it known that l, JACOB BUEsCI-I, of Milwaukee, in the county of Milwaukee,and inthe State of Viseonsin, have invented certain new and useful Improvements in Alarm-Counters for Printing-Presses, Smc.; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to improvements in alarm-counters, and will be fully described hereinafter.

ln the drawings, Figure l is a top view of my improved counter after its dial andvhands have been taken on". Fig. 2 is a like view of my device with the dial and hands in place. Fig. 3 is a partial detail view of the actuatinglever and a portion of the pawl connected thereto.

The object of my invention is to provide a simple mechanism which can be connected with any oi' the moving parts of a machinen such as a printing-press-so as to register every stroke or revolution of the same, and to sound an alarm after a predetermined number of strokes or revolutions have been accomplished.

A A is the box inclosing the counting mechanism and alarm.

B is the dial, which may be divided or graduated in any manner desired.

C is the actuating-lever, which is adapted to oscillate with every revolution of a press, or ofany other machine,by connecting its outer end projecting through the slotted side ofthe box with any ofthe moving parts of said press or machine. This actuating-lever is pivoted at a suitable point in the bottom of the box A, and in the bracket-plate c on the ful- Crum-pin c', journaled therein, a spring, c2, suitably attached to the lever, andthe free end ofwhieh spring presses against the bracketfastening screw o, serves to keep said lever in its normal position. The short arm of the lever C is provided with an extension, c4, that is suitably hollowed on one side to receive the pawl C', supported therein on the pivotingpin of. The free end oi this pawl is suitably notched on its inner face, so as to fit in either one of the notches formed by the teeth d cl d of the ratchet-wheel D, a spring, c, suitably fastened to the pawl C', and the free end of Serial No. 139,237, (No model.)

d', is made to project slightly above the upper f face of the dial B, and carries the unit-hand DZfastened thereon by means of the screw d2. Below the rateheted rim of the wheel D a tooth, d3, is provided in said wheel, and this tooth at every revolution of the wheel D will come in Contact with the tooth e, formed on the inner end of the lever E. pivoted on the fulcrum-pin e, projecting from the box-bottom, is kept in its normal position by means of the spring e2, and carries, hinged on the end of its long arm, the spring-pawl e3. The free end of this pawl e" is kept by its spring e against the ratcheted rim ofthe wheel F, suitably journaled in the bottom ofthe box: and in the inner end ofthe bracket D.

The upper end of the stem f is made to project sufficiently above the dial B to enable the hand F', which is fastened on its end by the This latter, which is' screwf, to clear the unit-hand D2 as said hand f F revolves around the dial. A detent-lever, di", provided with the spring d6 and .pivoted ,in the bracket D, serves to secure the wheel D against backward motion.

WAnother detent, G, pivoted in the bracket g, is provided withA a spring, g. that holds its detent in engagement with thel toothed periphery of the wheel F. This detent G is provided with a hand-lever, g2, which serves to raise said detent when it is necessary to adjust the hand FC This detent being lifted, the wheel F, to which said hand F is fastened, can be turned with ease to any 'ligure of the dial B. The wheel F, which is provided with one hundred teeth, has also a pin, f2, that projects upward from one of its arms, and when the device is -put together the pin is made to coincide with the starting-point or gure 10() of the dial B.

The adjustment of the hand F is effected by loosening the screw f', by means of which the said hand is fastened onto the outwardprojecting stem f of the wheel F, and `by turning the said hand so that. it points to the figure of roo the dial corresponding to the number of quires of paper it is desired to pass through the press, the screw j" being then turned to secure thehand in position, the detent G is disengaged from the wheel F, and the said wheel and its hand F are turned around so as to bring the hand F to the starting-point of the dial.

In the path of the pin f" lies the outer end of the lever H, which is pivoted on the fuleruin-screw 71 and is kept in its normal position, as shown, by means of the spring h. A stud, h2, formed on the upper face of the lever H, close to its pivoted end, is horizontally perforated to receive the inner end of thelever if, fastened therein, and carrying on its outer end the striking-hammer h.

H is the bell or gong against which this latter strikes. It is suitably mounted on the bracket h5, fastened in the bottom of box A` and the dial B isperforated, as shown at h It, opposite the bell or gong to allow the sound of thc strikinghammer to be distinctly heard.

The operation of the alarm-counter, as applied to indicate the number of sheets of paper printed on a press, is as follows: The box A having` been set in a suitable place, and the actuating lever C being suitably connected to any ot' the moving parts of the press, the hand Di is turned so as to point to the igu re 24C, or the starting-point of the unitdial. The hand F is then loosened and turned to the ure of the dial B which corresponds to the number of quires ot' paper to be printed. The screw f is turned and the hand made fast with its wheel. The handlever g2 is drawn out to disengage the detent G from the ratcheted rim ot' the wheel F, which is then moved around with its hand F till the point of this hand is opposite the figure 100,011 the startingpoint ot' the counter. At every revolution of the press the lever G will push the pawl'G against the toothed periphery of the unitwheel I), which will thus be moved one step, the same to be secured against backward motion by the pawl or detent da. W'hen the unitwheel D, which is provided with twenty-four teeth, will in this mannerhave moved twentythree steps, the tooth d3 will have been brought in contact with the tooth c of the lever E, and f at the next stroke or revolution of the press and of the pawl C the said tooth @will be pressed out, and the pawl e, carried by said leor strokes of the press.

ver E, will be moved with it against the ratcheted rim of the wheel F, moving this wheel one step for every complete revolution of the wheel D, or for every twenty-four revolutions When a sufficient number of the revolutions of the unit-wheel has been reached to bring` the hand F 0pposite the ligure ofthe dial B at which the said hand has been at first adj usted. as above mentioned, the vertical pin f2, carried on the upper face of one of said wheel-arms, will have been brought in contact with the level' I-I, which, when released from the same, is pushed back by its spring, causing the hammer 7L* to strike against the bell or gong H.

Although I have herein particularly de- ,scribed my device as connected with counting sheets of paper as printed on a press, it will be understood that I do not limit myself to such use, as the device is adapted for use in connection with any machine in registering the number ot' its revolutions or strokes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In an alarm counter, the lever C, having the hollowed-out extension et, and the pawl G, pivotally connected to said extension, in combination with the wheel D, having the tooth d, the lever E, pawl et, detent dt", wheel F, and a suitable actuating mechanism, sustantially as and for the purpose set forth.

2. In an alarnrcounter, the combination of the inclosingbox A, provided with an alarm, and a striker for the latter, the wheel F, hav ing the pin f2 on one of its arms, the detent G, the lever G, having the hollowed-out eX- tension et, pawl C', pivotally connected to said extension, the wheel I), having the tooth di, the lever E. springpawl e, detent d5, and a suitable actuatingmechanism, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county ot' Milwaukee and State of Vis cousin, in the presence of two witnesses.

JACOB RUESCH.
