' Specification of Letters Patent.

Patented Feb. 18, 1906.

Application filed lay 10.1907. Serial No. 372.901.

To all wiwin it may concern: Be it known that I, SWINFEN BRAMLEY- 'MOORE, a subject of the King of Great Britters, of which the following is a full and complete specification.

This invention relates to an'im'proved construction of liquid meter. 1

In the accompanying drawings which illustrate this invention:-Figures 1, 2 & 3 are views in sectional elevation showing one from of the apparatus; Fig. 1 showing the parts in the positions they oceufpy when the iquid has just commenced to ow into the measuring vessel; Fig. 2 showing the parts in the positions they occu y when the measuring vessel is nearly fu l, the inlet valve having shut off the supply; and Fig. 3 showing the parts. in the positions they occupy when the measuring vessel has descended and the bulk of the fluid passed out of the measuringvessel into the case. Fig. 4 is a view in side elevation, partly in section, showings. modification, the respective parts being in the same positions as they are shown in Fig. 1.

Throughout the views similar parts aremarked with like letters of reference.

Referring to Figs. 1, 2 & 3. In a suitable case a is a rising and falling vessel b-hereinafter called the measuring vessel. This vessel is carried by two arms It (only one of which is seen in the drawing) pivoted at h to the case a. On or in the top of the case a is a chamber 0 provided with an inlet passage a leading into said chamber, the opening into said chamber being .closed by a spring-controlled valve d. The chamber 0 is provided with a siphon outlet pipe on leading into the case a above the vessel b. Mounted in suitable guides in both the chamber 0 and the vessel b is a vertically arranged rod e adapted to operate the valve d through the rockmg lever e pivoted on the exterior of the chamber c, and at a suitable position on this rod is a shoulder or collar. On the bottom of the vessel 1) are ivoted two rocking levers e e the inner en' s of. which contact the shoulder or collar on therod e and the outer ends are ada ted to engage the bottom of the vessel b. in the measuring vessel b is a float e which, when the said vessel is empty, rests on the outer ends of the levers e e and so operates to keep the valve (1 open. In the bottom of the measuring vessel is an opening leading into the lower part of the case a, the said opening being closed by a valve f adapted to e opened by the descent of the mensuring vessel which causes the stem f of the valve to contact the bottom of the case a. The lower part of the case a is provided with an outlet siphon pi e l. Pivoted at g to the case a are a air 0 counterweights g and g each carried y an arm 9 Thesecountetweights are connected to the measuring vessel by the arm g and the link 7c connected to the arms h.

The weight of thecounterweight g is equal to a predetermined portion, say fiveeighths, of the weight of the liquid admitted to the measuring vessel at each operation of the apparatus. and. the weight of the counterweight g is slightly in excess of the weight of the measuring vessel and its appurtenances. In the case a is a float which is connected by a link j with an arm 1 pivoted to the case 41, preferably at the same point It as the levers It. The free end of the arm 7' is shaped to engage a stud g on the counterweight 9 so as to lock it in its raised position until the vessel 1) has discharged the bulk of its contents. In

' order to prevent a vacuum being, formed in the chamber a it is provided with a small air hole such as a The action of the apparatus is as follows 1* Assuming the apparatus to be empty and that liquid is permitted to flow into the pi e a, itpasses through the valve (1 into t e chamber 0 and from thence through the siphon pipe a into the measuring vessel 1) which is at its highest position. As the liquid accumulates in the vessel b it causes the float e to rise, which thereby releases the rod e and allows the valve (1 to be closed by its spring, thereby shutting off the supply of liquid when the predetermined quantity has passed into the chamber 6. When a prede 'termined quantity of fluid in the chamber a has passed into the vessel 1) its weight overbalances the counterweights g and g and the vessel begins to sink, and when it reaches its lowest. position the counterweights have been raised to such a position that the center of gravity of the counterweight g is approximately in a vertical plane with the pivot on which it swings so that its influence is negative. As the Vessel b sinks and reaches its lowest position the stem f of the valve fcontacts the bottom of the case a and thus opens After this locking the said valve and allows the liquid to flow out of the measuri vessel b into the lower part of the case a. the -li uid rises in said case the float j operates to 100 the counterweights and so prevent them raising the said vessel and restoring it to its h' best position.

is efiecte the outlet siphon pipe comes mto action and empties the case WhlOh causes the float 1' to sink and unlock the counterwe' hts, thereby allowing the vessel to be raise As the liquid asses out of the vessel 6 the float c sinks an coining in contact with the rockers e o crates them so as to lift the rod e so that w en the vessel rises the said rod e contacts the lever e and thus opens the valve d. In due course the measuring vessel is again filled 1 with liquid, when the sequence of operations is automatically repeated until either the suppl of liquid is cut off or the flow of liquid out o the case ais stopped automaticall by the level of the liquid in a receiver reaching such a level as to stop the action of the siphon outlet'pipe Z. V V

In the modification shown by Fig. 4 the float e operates the valve (1 through an arm n which is pivoted E) the case a and connected to the float e by a link n. The arm n is connected with one or both of the levers h by a lever n pivoted at n to one or both of the levers h, the one end of said lever n engaging the free end of the arm n and the other end engaging a finger n sliding in the to of the case a and adapted to contact the va ve d so as to o erate to open it. To prevent any ossibility of the measuring vessel partially descending from its highest position and then forming a erfect balance with the counterweight an so remaining in a midway posi- 'valve f is opened by a projectionf on its head engaging a stop a on the side of the case a as the measurin vessel descends. is connected t rough the link j? with an arm m pivoted on the pivotal shaft g carrying the arms of the counterweights, and to w ich the arm 9 is fixed, so that it o erates directly to control the time at which t e measuring vessel will rise.

The apparatus is provided with any suitable recorder', but this forms no part of the present invention.
