DANIEL E. S GRAFFOR-D. F PEORIA, ILLINOIS, ASSIGNOR, BY MESNE TO WILLIS ELECTRIC OF ILLINOIS.

Be it known that I, DANIEL E. Scnarronn, a citizen of the United States,residing at.- Pe'oria, in the county of Peoria and State ofdllinois, have invented cer ainnew and "-iiseful ln'iprovements in Registers; and I do hereby declare that the following is afull, clear, and exact. description of the invention,

' which will enable othezs skilled in the art to which it appertains to make and use the same.

This invention relates to registers for meters,' and refers more particularly to that class of registering devices in which the counting and indicating mechanism operates by an instantaneous 0r snap movementto record the measurement of the meter.

The object of my invention is to provide a simple and substantial register of the above class in which the power required to operate the same is uniform at all times and which requires no increase in power at the time the change in the recording mechanism is ctlected,'--and my invention has other "features of improvement which will be fully "set out in the following description and particularly pointed out in the claims fol lowing cation. Y

ln the accompanying drawings. which illustrate my invention, and in which similar reference characters indicate similar parts in the several views. Figure 1 is a front view oil the top portion of a con'inion and forming a part of this specifigas meter showing a face view of a regis ter containing my improvements; Fig. a

The front and rear plates 1 and 2 re- .spe'ctively are. spaced a suitable distance apart and held together by means of the posts 3, and form bearings for the'operative parts of the register.

METER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION REGISTER.

operating diaphragms of the meter in the usual manner has a hand 5 fixedly held on the front end thereof which turns around a dial 6 on the "face plate 7 which is suitably secured to the front plate of the register, and each revolution of the said hand represents the passage of a comparatively small volume of through the meter, which in the register herein shown and described is two cubic feet. Y

Upon the shaft or spindle 41-, intermediate of the plates 1 and 2 is a worm 8 which meshes with an elongated worm gear-9 fixed on the shaft 10 which extends parallel with the-plate Qand is journaled in the bracket hearings '11 secured onto the rear plate 2. This shaft 10 is adapted for a limited longilP'atented Feb. 22, 1910.

tudinal movement in the bearings 11 and in every position of the longitudinal movej ment of the shaft 10.

The counter mechanism of this register is of the common type comprising toothed wheels 12. 13 and 141 on the shafts 15, 16 and 17 which said wheels are arranged to operate the Geneva gears 18, 19 and 20 re-- spectively which are carried respectively on the shafts 16, 17 and 21. This counter mechanism is arranged in the usual manner, and each Geneva gear is constantly locked against movement by means of its operating one toothed wheel and it requires ten'rcvolutions of each one toothed wheel to effect one revolution of the Geneva wheel which it engages. The register herein shown is what is known as direct reading and'the count thereof is indicated by the usual numbered dials 2'2, 23 and 24. on the shafts 16. 17 and 21 respectively, the numerals of which said dials appear, one at a time, through their respective sight openings 25, 26 and 27 in the face plate 8, the front plate 1 being cut away as shown back of said openings. The dials 22, 23 and 24' indicate hundreds; thousands, and ten. thousands respectively and one step of each dial represents the passage of one hundred, one thousand and ten thou-. sand cubic feet, respectively through the meter. Additional dials may be used if desired to register higher amounts.

On the shaft 1.5 is a spur gear 28 which.

meshes with the worm 29 on the shaft 10 so that when the shaft 10 is rotated the worm 29 tends to rotate the spur gear 28.

For the purpose of delaying the operation of the counter mechanism until the unit of volume indicated by the next change in the recording mechanism has just passed through the meter. and for the purpose of rendering the operation of the indicating mechanism instantaneous, the shaft 16 is arranged to gradually shift, longitudinally during the rotation thereof so that the worm 29 imparts no movement to the spur gear 28 until the end of the revolution of said shaft 10 when the shaft is returned to the initial position with a snap movement which jttllIlS the spur wheel 28 and operates the counter on longitudinally in the direction indicated by the arrow in Fig. 3 so that the thread of the Worm merely moves through the teeth of the spur gear 28 and holds said gear stationary until the offset 31 of the cam passes the corresponding offset of the cam 32 when the shaft 10 is free to return to the initial position and turn the spur gear 28.

Numerous means may be employed for returning the shaft 10 to the initial position. In Figs. 2 and 3, I have shown a bracket 38, pivoted on the spindle 39 and provided with a depending portion #10 which bears against the rounded projecting left end of the shaft 10. The bracket 38 supports a weight 37, and as the shaft-1O is moved longitudinally toward the left. by the cam members, the bracket with the weight is swung. and when the cam 31 reaches the offset of the corresponding cam 32, the weight bracket is released and'swings to its normal position to quickly return the shaft 10 to its initial position. In place of the weight, its mechanical equivalent, such as a spring may be used.

In Fig. 5, I have shown a somewhat moditied arrangen'ient of the cam mechanism and returning mechanism. Instead of having the cam member 30 engage a similar stationary cani member 82, I provide a roller 43 pivoted to the frame 2 and in position to be engaged by the cam surface of the cam nicm ber 80. As this cam member rotates over the roller, the shaft 10 is moved to the left and suddenly released, when the offset 31 the shaft to ipitial position, a cam member 33 is securedto the shaft. which has a cam surface substantially similar to that of the member 30. A roller 41 engages the cam surface of member 33 and is pivoted to the frame 2. roller 43, the ridge 33' of the cam member engages with roller 4A and quickly forces the shaft 10 back to its initial position. As shown in Fig. 3, the shaft 10 is inclined, and the angle of inclination may be sutlicicnt so that the force of gravity will tend to return the shaft 10 to its initial position after an upward longitudinal movement thereof and the form of return mechanism shown in Fig. 5 is preferable where an in clincd shaft is used. If the shaft does not return immediately by the force of gravity and sticks, the cam ridge 33 striking the roller 41 starts the shaft 10 so'thal it will return to its normal position.

ill [any other modified arrangements are also possible Which will still come within the scope of my invention, and I desire to secure the followin claims by Letters Patent.
