ELECTRlCALLY-OPERATED REGISTER.

SPECIFICATION forming part of Letters Patent No. 522,113, dated June 26, 1894.

Application filed October 23, 1891. Serial No. 409,610- (No model.)

To aZZ whom it may concern.-

1 3e it known that I, SHELDON J. GLASS, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee, and in the State of WVisconsin, have invented certain new and usefulImprovements in Electrically-Operated Registers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates particularly to that class of registers employed for counting the movements of a reciprocating, oscillating, or rotary device, such for instance as a pumppist-on, rock-shaft or fly-wheel, and registers of thls class are also employed to automatically count certain manufactured articles as they are successively produced. Such registers ordinarily comprise a series of numbered dials representing units, tens, hundreds, (be, geared in train; and a lever-mechanism controlled by an armature, the latter being moved 1n one direction by an electro-magnet, energlzed at certain intervals, and recovered by a spring, on the de-energization of the magnet. In practice, the employment of a spring, to recover the lever-mechanism, has been found unsatisfactory because of the liability of the electro-magnet to be energized at other than predetermined intervals and thereby overcome said spring, thus producing a wrong count. To do away with the spring and insure a correct count by the register is the obect of my invention, and the latter primarily consists in combining the lever-mechanism and its controlling armature with two electro-magnets alternately energized to attract said armature in opposite directions. In other words, I substitute an electro-magnet for the spring in common use, the result being that When the armature has been attracted by one of the eleotro-magnets, it will require a cutting out of the latter and an energization of the other electro-magnet before said armature can move in the opposite direction, and consequently a false count is impossible, no matter how often either magnet may be energized before the other.

In the drawings forming part of this specification: Figure 1 represents an elevation illustrating certain parts of an automatic register embodying my invention, a one tooth gear-wheel and a units dial (the latter in dotted lines) constituting parts of an ordinary counting-mechanism being detached because of a section taken transversely through a relative stud and ratchet wheel sleeve; Fig. 2, a plan view of the same, and Fig. 3, a dia gram illustrating the armature and electromagnets of my improved register in connection with a rotary device for making and breaking circuits in which said magnets are located.

Referring by letter to the drawings, A repplates B, C, of the register-frame are rigidly secured by any suitable means. Arranged to turn on a stud Z) on the front-plate O is a sleeve 0 carrying a ratchet-Wheel d, a one tooth gearwheel 6 and a units dialf, the gear-wheel being part of a train, not shown, that controls the movement of other dials representing tens, hundreds, &c., locked against withdrawal from their bearings by the usual pivoted latch X shown in Fig. 1, each of the latter dials being moved one-tenth of a revolution on the completion of a full revolution by the dial of next lower denomination. The ratchetwheel d is alternately engaged by pallets g, g, on a lever D that rocks on an arbor E extended laterally from the front plate above described, and this lever is connected bya link F, with another lever G, the latter being trunnioned intermediate of its ends in bearings h that extend laterally from the back-plate B specified in the foregoing. Carried by the lever G is an armature II arranged intermediate of two electro-magnets I, J, these magnets being wired to a suitable source of electric generation in independent circuits.

In registers having a single electro-magnet, the energization of the latter causes an attraction of the armature and consequent movement of the lever mechanism to actuate the counting mechanism, and upon the breaking of the circuit controlling the magnet, said lever mechanism is retracted to its normal position by a suitably arranged spring, consequently this spring is overcome every time the circuit is closed, whether predetermined or otherwise, and a Wrong count is the result. By the employment of two electro-magnets, arranged as above described, and each having its own circuit, the energization of one will cause an attraction of the armature there resents standards to which the back and front to and this armature will remain in the position to which it has been drawn after the circuit has been broken',vit requiring that the other magnet be energized before said armature can be retracted. It therefore follows that no matter how often the first magnet maybe energized after the armature has been attracted thereto, there will be no movement of the counting-mechanism after the first contact of said armature and magnet, and that this magnet must be de-energized and the other energized before it is possible for the aforesaid armature to retract and bring the lever mechanism to its original position.

As herein shown an attraction of the armature H by the magnet I will cause the pallet g of lever D to engage and push against the ratchet-wheel d, and the retraction of said armature by the magnet J will cause the pallet g of said lever to engage and lift against said ratchet-wheel. By this alternate action of the pallets against the ratchet wheel, the units dial is moved .twice to one count, but this is a matter of arbitrary determination that may be varied to suit the employment of the register.

Referring more particularly to Fig. 3, it will be seen that a pivoted circuit-closer K has been in contact with the terminal dot the circuit controlling the electro-magnet I, and

that the armature H has been attracted by said magnet to thereby actuate the lever D. Now, if the circuit closer touch the terminal j of the circuit controlling the magnet J the latter will be energized to retract the armature and bring the said lever to its normal position.

The circuit-closer may be an attachment to any device having motion, or the device itself may constitute a circuit closer, and it will be readily apparent, from the aforesaid diagram View, that said circuit-closer may come on and off either of the terminals 6, 7', any number of times, after the first contact and before touching the other terminal, without in any way, affecting the counting mechanism. The circuit-closer may be also actuated by a su table mechanism placed in the path of certain articles of manufacturesuccessively produced this being common in the art to which my invention relates.

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

A register of that class employed for counting the movement of a reciprocating, oscillating, or rotary device or the successive production of various articles, the same comprising a series of counters geared in train to indicate arithmetical progression in the order of units, tens, and multiples of ten, a ratchet connected to the units-counter, an actuating lever for the ratchet, another lever linked to the one aforesaid, an armature carried by the second lever, an eleotro-magnet for the attraction of the armature, and a supplemental electro-magnet for the retraction of said armature, each of these electro-magnets being in independent circuit and automatically cut out prior to the energization of the other, substantially as set forth.

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