REGISTER FOR WATER=METERS.

SPECIFICATION forming part of Letters Patent No. 393,102, dated November 20.1888.

Application filed March G, 1886. Renewed September 2-1. 1888.

To all whom it may concern:

Be it known that I, FRANKLIN T. GILBERT, of Walla Walla, in the county of lValla Walla, W'ashington Territory, have invented a new and useful Improvement in Registers for W'ater-Meters, &c., of which the following is adescription.

Figure 1 is a plan view of the register. Fig. 2 is a perspective view with the cover and dial-plate removed and parts broken away. Fig. 3 is a plan of the dial-plate; and Fig. 4is a cross'section, on a smaller scale, of the registor-case.

My invention relates to registers for measuring the number of revolutions of a fluid-meter; and it has for its object the construction of a register of most compact form, and which is not liable to be accidentally moved to indicate an incorrect registration or be easily doranged.

In the drawings, A representsa shallow chamber, whose vertical wall or flange is screwthreaded on the outside and engages with a detachable screw-collar, B, that fastens a glass plate, 0, over the top of the chamber, with a jointmade tight by a gasket, t. Into the center of this shallow chamber there extends the shaft D of the rotating wheel of the meter, to which shaft is rigidly attached the small gearwheel a, which meshes with a larger gearwheel, I), and which latter is adapted in number of teeth to indicatea certain definite quantity of fluid passed by the mete'ras one gallon, for instance. This wheel I) then becomes the units-wheel, and following it around within the chamberin regular sequence is the tenswheel 0, the hundreds-wheel d, the thousands-wheel e, the ten-thousands-wheel f, and the hundredthousands-wheel g.

These wheels are turned by the engagement of lug b of the units-whcel with the wheel 0, and all turn loosely upon center pins, 1) c e c f g, which latter are eitheraffixed to the bottom of the chamber A or to a thin detachable plate arranged in the bottom of said chamber. All the wheels from c to g rest fiat upon a bed, E, of soft rubber, which is held in place against rotation bytheprotrnsion of the center pins, 0 to g, through the same, and furnishes a sufficient friction to hold the wheels to the position to which they may be turned without allowing Serial No. 286,236. (Model) them to be accidentallyjolted orjarred out of position. All these wheels rest in the same plane, and this constitutes one of the peculiarities and advantages of my invention, for it enables me to arrange the registering mechanism in the shallowcst possible chamber, (in contradistinction to having a progressive series of wheels extending always away from the plane of the first, as is usual.) In order to render it possible to have these wheels all in the same plane, I provide a peculiar construction and interrelation for these wheels, as follows: 1

Each wheelhas a circle of teeth, and just beside it a single tooth, c d 6 8.10., and the circle of teeth of one wheel is in the same plane as the single tooth of the next wheel and in range of engagement therewith; but in order to render such a train operative in correct registration it is necessary to make all the wheels after the tens-wheel with eleven teeth instead of ten. The cause of this is that once in the revolution of each wheel (above the tens) each said wheel is necessarily moved two teeth by the double action of the single tooth of one wheel upon its neighbor and its neighbors single tooth upon itself. Thus as long as the single tooth c" of the tens-wheel 0 simply engages the circular series of teeth of the hundreds-wheel it moves the latter but one tooth each revolution; but when the single tooth d of the hundreds-wheel comes round opposite the tenswheel, then when the single tooth of the tens-wheel acts upon the hundredswheel said single tooth of the tens-wheel moves the hundredswheel one space, and immediately the single tooth of the huinlredswheel, engaging the circle of teeth of the tens-wheel, is moved another space, thus causing at this c0- incidence or conjunction of single teeth a double movement of the higher wheel. It is obvious, therefore, that to preserve the proper relation of the wheels in increasing by tens it is necessary to add to the wheels (above the tens) the extra eleventh tooth in the circular series, and this enables me to have a perfectly flat train of wheels, in which all are in the same plane. The indexhands of these wheels are in the nature of pointed lugs c (Z c f which point each to a circular row of figures around the margin of a set of holes in a dial- ICO plate, F, which rests loosely within the chamber A and bears upon the outer periphery of the wheels, so as to increase by its weight the friction of the wheels upon the rubber bedbelow. At the point where the dial-opening of each wheel approaches the dialopening of the next lower denomination it will be seen that twice thedistance exists between the two figures of the higher series at this point than exists between the other figures, which simply adapts the dial to the increased throw of the wheel which occurs at this point. This increased space between the figures also secures an advantage, in that it allows me to put the eircu-' lar series of figures close together without in terference.

Having thus described my invention, what I claim as new is- 1. A register arranged to count decinially and having its gears constructed and arranged with a single tooth meshing with eleven teeth, substantially as and for the purpose set forth.

2. A register arranged to count deeimally and having its train of gear-wheels constructed with eleven teeth on one side and one tooth on the other, and with said wheels alternately reversed,with the single tooth of one wheel meshing with the circle of teeth of its neighbor, in combination with a dial having twice the space between its figures at one point in its graduated face that it has between the other figures, substantially as and for the purposes described.

3. The combination, with the outer ease and the denornination-wheels arranged in the same plane, and provided with index-lugs, of the dial-plate F, made as a loose disk resting with its full weight upon the tops of the wheels and furnishing a friction thereto, the said dialplate being perforated with openings for the denomination-wheels, and provided about the margin of said openings with series of figures, substantially as shown and described.
