VILLIAM DH. WASHINGTON AND FREDERICK C. GOODWIN, OF NEW YORK, N. Y., ASSIGNORS TO THE WASI-IINGTON-GOODVIN METER COMPANY, OF
LIQUID- METER.
SPECIFICATION forming part of LettersPatent N o. 643,432, dated February 13, 1900.
Application filed May 29, 1899. Serial No. 718,766. (No model.)
To all whom it may concern:
Be it known that we, WILLIAM DH. WASH- INGTON and FREDERICK C. GOODWIN, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Liquid-Meters, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates generally to meters and has particular reference to an improved water-meter adapted for use in measuring the quantity of water drawn from the mains for use in houses or factories.
The principal object of our invention i`s to produce a meter of the kind referred to comprising in its formation but few and simple parts, the latter being so arranged and constructed as to be readily removed when worn to allow of new parts to be substituted in their places or adjusted relatively to each other to compensate for their wear.
With this object in view our invention consists in a novel type of water-meter and in the peculiar construction, arrangement, and combination of the various parts thereof, as more fully hereinafter described, and shown in the drawings, in which- Figure l is a horizontal sectional View on line 'y @j of Fig. 2. Fig. 2 is a sectional view taken on the line of Fig. l. Fig. 3 is a sectional perspective view, the section being on line z z, Fig. 2. Fig. 4. is a perspective View of the lower section of the meter-casing. Fig. 5 is a sectional View similar to Fig. 2, illustrating a modified form of backing.
The reference-letter A designates a cylindrical meter-casing comprising a lower section or bodyB and an upper section or top C. The lower section is provided with a central recess D, formed in the lower side or wall thereof, and the upper section has formed therein a corresponding recess E. Fixedly secured by means of suitable bolts a to the meter-casing is a housing F, in which is arranged the usual reducing-gearing for the meter.
Within the cylindrical meter-casing is arranged a rotaryT piston G of less diameter than the casing and arranged concentrically within the latter, forming an annular passage H, surrounding the piston. Within this passage and preferably diametrically arranged are inclines I and J, the incline I having formed therein a port b, which leads into the supplypipe K of the meter, and within the incline .T is formed a similar port, which communicates with a discharge-pipe L. Arranged within one-half of the annular passage and detachably secured to the casing is a backing M, said backing being provided'with laterallyextending lugs d, which abut against the shoulders e on the inclines. The lower wall of the section B is centrally apertured, as at f, and a similar aperture is formed Within the upper section O of the meter-casing. lVithin the aperture f is adjustably secured a post comprising an enlarged threaded portion g, arranged within the aperture, and a reduced portion or pin h, which extends within the meter-casing.
The reference-letter i designates a threaded bushing adjustably arranged within the aperture formed in the upper section, and N designates the piston-shaft, comprising an enlarged portion j, having a socket formed therein, and a stein 7c. The socket is adapted to be arranged over the pin h, and the stem 7c extends through the bushing up into the housing F.
The reference-letter Z designates a gearpinion arranged upon the end of the stem lo, which is adapted to mesh with one of the gearwheels of the usual reducing-gearing, which, being of ordinary construction and not constituting a part of this invention, is not shown.
The piston G is iixedly secured to the enlarged portion of the shaft N in any suitable manner and comprises in its construction an upper section O in the form of a plate or disk, and a lower section P of similar form, each being centrally recessed to permit of their being sleeved over the shaft.
The lower section of the piston is provided with a depending annular ring ct and an inwardly-extending annular iiange b', and between the Iiange and under face of the lower disk are arranged a series of spaced bosses c', as plainly shown in Fig. 1. Each boss is slotted, as shown, the slot extending entirely IOO through the boss and annular ring and into a portion of the lower disk, whereby a series ot' radial recesses d are formed within the piston, in which are arranged a series of rectangular gates or wings Q. To prevent the liquid which enters the annular passage from entering the piston-chamber above the piston, we provide an annular flange c2 upon the upper section of the piston, which extends within the recessed portion of the upper section of the casing and bears constantly against the casing. A similar ilangeftis provided for the lower section of the piston, which acts as a guide to steady the movement of said piston. The liquid entering the casing below the piston is prevented from ascending by means of the peculiar construction of shaft that has heretofore been described.
The reference-letter R designates a cam, against which the inner ends of the rectangular wings are adapted to bear for the purpose of being projected outwardly across the annular passage in the path of the Huid. This cam comprises a cam portion S, mounted upon standards T, the standards in turn being adjustably secured by means of bolts h' to the bottom of the meter-casing.
The meter having been thus described, the operation of the same is as follows: The parts being arranged as in Fig. 2, the liquid entering through the supply-pipe K passes through the annular passage and striking against the wings extending in said passage causes the` piston to rotate. The incline I acts as a guide for the wings as they are forced out by the cam, while the incline J constitutes the means for returning the extended wings to their initial position, the portion of the cam adjacent to said latter incline acting as a guide for the wings.
It will be observed from the construction of the mechanism as thus set forth that the backing or wear-plate that we employ may be readily detached from the meter-casing and a new one substituted in its place when desired; likewise, that the cam may be adjusted as desired to compensate for wear or may be readily removed and a new cam inserted. It is also to be noticed that the parts of the mechanism as set forth are simple in construction and few in number, producing a meter capable of being manufactured at a minimum cost.
In Fig. 5 we have shown another type of backing, which is in the form of a ring W, adapted to tit tightly within the annular passage. This ring is provided with inclines 9^ and s, corresponding to inclines I and J, (shown in Fig. 4, and with a reduced portion if, the inclines and the reduced portion upon the ring forming a passage leading from one inletport to the other. The part of the ring opposite the reduced portion is adapted to entirely fill the annular passage and constitutes the wear-plate or backing for the piston.
What we claim as our invention is- 1.
