ELECTRIC METER.

SPECIFICATION forming part of Letters Patent No. 440,431, dated November 11, 1890.

Application tiled February 26, 1890. Serial No. 341,794. (No model.)

To all whom, t may concern:

Beit known that I, ETIENNE iWIAREscf Paris, France, have invented a new and Improved Meter, of which the following is a full,clear, and exact description.

The object of the invention is to provide a new and improved meter, whichis simple and durable in construction, very eiective in operation, and adapted for all purposes for which meters are generally employed, especially, however, for measuring electricity and other iuids and substances.

`The invention consists ot a balanced lever on which is mounted to travel a carriage adapted to engage a registering wheel or cylinder.

The invention also consists of certain parts and details and combinations of the same, as

will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is asectional side elevation of the improvement as arranged vfor measuring electricity, on the line fr of Fig. 2. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation of the improvement. Fig. I.tis a side elevation of the same in a different position. Fig. 5 is a side elevation of the improvement in a modified form. Fig. 6 is a similar view of the same in another position. Fig. 7 is an enlarged end view of the locking mechanism for thebalancedlever,which latter is shown in section. Fig. 8 is a front viewof the same in an unlocked position. Fig. 9 is a similar view of the same in alocked position. Fig. l0 is an enlarged transverse section of the balancinglever and the carriage. Fig. 1l represents detail side and end views of the locking-arm for the'locking mechanism, and Fig. 12 is an enlarged side elevation of part of the carriage.

The improved meter is provided with a balancing-lever A, fulcrumed at a knife-edge B, and on which is mounted to travel acarriage C, adapted to engage and disengage a wheel D, connected with the registering apparatus E, as shown in Figs. 1 and 2. The carriage C is provided with a platform C', mounted on wheels C2, traveling in a groove A',formed in the top of the balancing-lever A, (see Fig. 10,) and from the said platform extend obliquely downward, the rods C3, supporting a weight C4, preferably a casing filled with shot.

The weight C4 is arranged below the knifeedge B of the lever A, so as to bring the center of gravity in a vertical line which passes thrmlgh the kuifeedg@ of the lever. Nhen the lever A is in its normal horizontal position, as shown in Fig. 3, and the carriage travels on the saine, then the wheel D is turned by contact with the platform C of the rolling carriage; but when the lever A oscillates in one direction, as shown in Fig. 4, the carriage disconnects from the wheel and the latter stops turning. Thus the essential point of the invention is a carriage mounted to travel on an oscillating lever and adapted to engage or disengage the controlling-wheel of a registering apparatus, which may be of any approved construction.

In Figs. 5 and G, for instance, is illustrated a carriage C, which is provided on its platform C with a stylus or marker F, adapted to mark on the periphery of the cylinder D', which is mounted to turn. The lines traced along the cylinder are parallel to the axis of the same, and vary in length according to the length of time the stylus F is in contact with the said cylinder D,which latter in this case is substituted for the wheel D, previously mentioned As illustrated in Figs. l and 2, the above-mentioned main feature of the invention is applied to an electric meter', presently to be more fully described.

The improved electric meter is mounted on a suitable base G, supporting the posts G', in which are mounted the knife-edges B of the lever A. On top of the lever A travels the carriage C, in a manner previously described, and adapted to be moved with its plat-form C in contact with the wheel D of the recording apparatus E. Directly below the front end of the lever A is arranged a Vatt meter H, comprising the coarse-wire bobbins lil and H3, between which is arranged the fine-wire bobb'in Hi in the usual manner, as plainly shown in Finn l. The iine-wire or center bobbin H2 is engaged by a Wooden block I, held on a wooden rod I', extending upward through IOO the central opening of the bobbins H2 and H to be hooked onto a collar l2, held adj ustably on the front end of the balancing-lever A, and adapted to be secured in place by a setscrew 13. On the base G are arranged the binding-screws J J', J2, and J3, of which the binding-screws J and J connect the apparatus with the source of electricity, which may be a dynamo, accumulator, dac. The binding-screws J2 and J3 connect the apparatus with the lamps or other means for using the electricity. The sh unt-wire H4 leads from the fine-Wire bobbin H2 to the binding-post J, and another wire H5leads from the said fine- Wire bobbin H2 to the binding-screw J', as is plainly shown in Fig. 1.

On the base G'is held in a suitable casing K a clock-work or other means for-imparting a rotary motion to a crank-disk K', connected by a pitman K2 with a lever L, fulcrumed at its lower end on a shaft L', mounted to turn in suitable bearings erected on the base G. The upper end of the lever L is provided with a slot L2, engaged by a pin N', held on the outer end of a rod N, supported on grooved rollers N2, mounted on suitable posts erected on the base G. On the under side of the rod Nis held a downwardly-extending projection N3, from which extends sidewise a pin N4, adapted to engage alternately the pins C5 and C3, secured on the under side of the platform C' of the carriage C. On the shaft L is also fulcrumed a lever O,V adapted to engage with its upper end a pin P', held on a lever P, fulcrum'ed on the balancing-lever A. On the lower end of the said lever P is arranged a pin P2, adapted to be engaged by a hook Q, held vertically adjustable on a bracket R, secured on the base G. The oscillating movement of the balancing-lever A is limited by the stop-screws S and S', arranged on the sides `of the knife-edge B, asis plainly shown in Fig. l.

The operation is as follows: The current of electricity passes from its source to the binding-screw J, then to the binding-screw J2, passing at the same time through the coarsewire bobbins H' and H3 of the Watt meter H, then re-enters the apparatus by the binding-screw J3 after having passed through the lamps or other means of using the electric current. The current then returns to the dynamo or other source of electricity by the binding-screw J The wires H4 and H5 are used-one before the entrance of the current into the apparatus and the other when the current has passed through the apparatus. N ow, supposing that at first no current passes through the apparatus, then the carriage C is moved so that the center of gravity of the balancing-lever A is displaced and the lever is oscillated immediately upon its knife-edge B, so that the platform C' of the carriage disconnects from the wheel D, which consequently does not lturn and the meter is not operated. N ow,if the current passes through the apparatus the bobbin H2 is attracted by the bobbin H3 and repulsed by the bobbin H. The fine-wire bobbin H2 thus presses on the block I, thereby swinging the balancing-lever A downward at its front end in the direction of the arrow a', so that the front end of the, balancing-lever rests on the set-screw S. The carriage C now travels on the balancing-lever A until it reaches such a position that its weight G4 will be sufficiently distant from the knife-edge B to balance the force applied to the end of the balancing-lever A through the bobbin H2. As the leverA oscillates, the pin P2 of the lever P hooks onto the hook Q, thus locking the lever A in position and preventing its rising on the return-stroke of the carriage. The pin P2 is disconnected from the hook Q when the lever P is operated on by the lever O, which engages the pin P' and swings with the lever L, imparting motion to the carriage C by means of the rod N, supporting the pin N4, acting alternately on the pins C5 and C6 on the platform C' of the carriage.

lt is understood that the distance traveled by a point on the circumference ofthe wheel D is equal to the distance traveled by the platform of the carriage C at the moment of the balancing-lever A is upset. Thus it will be seen that the wheel D is actuated at regular intervals, and the result can be read on the dial of the registering apparatus E to quickly calculate the electric power for a given time.

It is understood that the electro-dynamometer develops a force expressed by E. I. and integrated periodically at equal intervals of time. The length of the platform of the device is proportional to that force E.- I., so that the time during which the platform operates the counting-wheel is indicated and can be read on the dial; but this reading also gives the expression E. I. T.-that is, the electric power for a given time.

It is understood that the mechanism in the box K for imparting motion to the levers L and O and to the carriage Cmay be of any approved construction-an electric-clock movement, spring movement, or other device.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In an electric meter, the combination, with the balancing-lever mounted to oscillate and an electro-magnetic device for actuating said lever, of g a carriage on the lever, mechanism for reciprocating the carriage, and a registering device in the path of the carriage and separate and independent of the carriage and lever, substantially as set forth.
