WATCH MANS ELECTRIC REGISTER.

SPECIFICATION forming part of Letters Patent No. 253,962, dated February 21, 1882.

(No model.)

To all whom it may concern:

Be it known that I, GEORGE G. WEirrz, a

. citizen of the United States, residing at Boston,in the county of Suflfolk and State of Massachusetts, have invented certain new and useful Improvements in Watchmens Electric Registers; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawlugs.

This invention relates to improvements in watchmens electric registers; and it consists, in such a register, of an electro-magnet and its movable armature and connecting mechanism to a spring-driver, by means of which the latter is wound up by the'attractive power of the electro-magnet to move the stylus-bar across the face of the paper, as will be herein more fully shown and described.

Formerly the stylus-bar in watchmens electric registers was actuated by a weight and separate clock mechanism to move it across the paper, which required the attention and manipulation of winding up, and if the said weight was not wound up at the proper time the stylus-bar would not travel across the paper, and would consequently not register until the weight was again wound up.

My invention is automatic in relation to actuating the stylus-bar, and in this invention the usual weight and superfluous clock-work are dispensed with for moving the stylus-bar, and the latter is actuated by a spring-driver automaticallywound up by the initial blow of the armature-lever when the initial or first tooth of the contact-wheel in the box or transmitter strikes its contact-spring, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, in which--- Figure 1 represents a front elevation of the invention. Fig. 2 represents a side elevation. Fig. 3 represents a bottom view; and Fig. at represents a cross section in the line A B, seen from a: in Fig. 2.

dd are the soft-iron cores of the electro-magnet and c is the movable armature secured to the hammer-lever f, the latter being hinged or loosely suspended in bearings atf, as shown.

In the box or transmitter (J, c is the contactwheel, with its first or initial tooth, c, and additional teeth 0 0, according to the number of the box or transmitter, as usual.

0reprcsents the usual contact-spring in the box or transmitter O.

0 represents the armature-lever, secured to the armature 0 in a suitable manner. 0 is the extreme projecting end of said armaturelever c g is a ratchet-lever hung loosely at g, and provided with pawls g g, which actuate the 'I'atehetwheel h when the armature -lever 0 comes in contact with said ratchet-lever g during the initial blowof the armature 0 toward the electro-magnet. The ratchet-wheel his attached to a pin or sl1al't-,h,that passes through the springcase i, and within the latter is located the spring-driver it, one end of which is secured to the pin or shaft h and the other end to the interior of the spring-case i, in the usual manner of connecting spring-drivers to their case and ratchet-wheel.

To the spring-case i is attached the escapement-wheel I, having teeth Z l engaging with the pallet on on the upper end of the oscillating pendulumbar at, having secured to it the adjustable pendulum m, as shown.

On the circumference of the spring-case i are located projections i 'i',WhlGl],1l1 combination with the locking and releasing lever a a serve to keep the springcase i from turning after the spring therein is wound up until the projection c on the armature-lever 0 comes in contact with the part a of said locking and releasing lever, when it is turned 011 its fulcrum n and its other part, a, disengaged from one of the projections t" on the spring-case A light spring, a, serves to keep the lever end a in contact with the circumference of the spring-case 45 when the end a is not acted on by the projection c on the armature-lever c.

On the circumference of the escapementwheel 1 are located projections l l, which serve two pu1*poses--nan1ely, first to act on the pin 0 on the stylus-bar 0, and thereby cause the latter to move on its guide-bar 1) toward the right against the influence of the coiled spring q, during which motion of the stylus bar 0 the impressions on the sheet of paper r are produced, as usual, by the action of the hammer f on the stylus or marker 0 in the upper end of the stylus-bar 0. WVhen the stylusbar 0 has been moved toits extreme right-hand position itis released by one of the projections Z on the escapement-wheel l passing by the tooth or pin 0 on the stylus-bar 0, when the latter is automatically forced back toward the left to its original position by the influence of the spring q. The projections I also serve to act on the bent lever 8, moving on the fulcrum s and causing its upper end, .9, to depress the wind-up lever 9 after the stylus-bar 0 is released, so as to be in position for the next initial blow of the armature-lever 0 when the next box or transmitter is operated. t t represent the feed-rolls for the paper, as usual.

The operation of the invention is as follows: In winding up a transmitter, 0, its first or initial tooth, c, in closing the current by contact with the spring 0', causes an initial blow of the armature 0 onto the electro-magnet, and in so doing the armature lever 0 strikes the ratchet or wind-uplever g and winds the spring is sufficiently to carry the stylus-bar 0 across the paper 1' by the action of the escapementwheel projection l acting on the stylus-bar projection 0, and when the armature-lever c is near the end of its stroke its outer projection, 0, comes in contact with the releasinglever n, causing its end a to be released from the projection t on the spring-case t, by which the spring-case 'i and its escapement-wheel Z are set in motion by the spring-driver 7t, and thereby causing the stylusbar 0 to be carried against the influence of the spring q by the action of the projection I on the stylus-bar projection 0, during which time the armaturehammer f" strikes the stylus or marker 0 and punctures the paper 0" as many times as there are teeth on the transmitter contact-wheel c, excepting the first tooth, c, which is the initial opening-tooth. During this operation the wind-up lever g is kept in a raised position by its pawls until the projection l on the escapement-wheelpasses by the projection 0 on the stylus-bar 0, when the latter is actuated bythc coiled spring q and carried back across the paper to its original position at the same time as one of said escapement-wheel teeth 1 comes in contact with the depressing-lever s s, and actuates the latter to depress the wind-up or ratchet lever g to a position ready for the action of the armature-lever at its initial blow by winding any desired transmitter at any required station.

What I wish to secure by Letters Patent, and claim, is

' 1. Ina watchmans electric register, the electro-magnet a a (Z d and movable armature c, and mechanism connecting it to the springdriver k, by means of which the latter is wound up automatically by the attractive power of the electro-magnet, as described.

2. In a watchmans electric register, the combination of the movable armature e, armaturelever c, winding-up lever g, ratchet-wheel h, pawls g, spring-driver 7t, escapement Z Z l m m m, lockin g and let-oft lever an, projections '27 t" on spring-case 'i, projections l I on escapement-wheel Z, the depressing-lever s s, laterally-movable stylusbar 0, its tooth 0, and spring q, as and for the purpose set forth.

In testimony whereofI have afiixed my sig nature in presence of two witnesses.

GEORGE Gr. VVEITZ.
