T0 aZZ whom it may concern.-

Be it known that I, JAMES A. TILDEN, a citizen of the United States, residingat Hyde Park, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Meters, of which the following is a s ecification.

My invention re ates to meters, and more particularly to those of the current type.

ts principal objects are to provide an effective apparatus of this character.

It consists in the various features and combinations hereinafter described and more particularly claimed.

In the accompanying drawings, Figure 1 is a central vertical longitudinal section through one embodiment of my invention. Fig. 2 is a top plan view with the cover removed. Fig. 3 is a broken horizontal section on the line 3 3 of Fig. 1. Figs. 4 and 5 are perspective views of the deflector and wheel, respectively. Fig. 6 is a top plan view of said wheel, and Fig. 7 is an enlarged sectional detail of the step or thrust-bearing taken in a plaie between the arms of the supporting- SP1 er.

Similar characters indicate like throughout the several figures of the mgs.

10 designates an outer casing having an upward extension 11, which is open at the arts top and which may be closed by a cover 12.

This cover carries the usual register mechanism 13. In the casing is formed an inletpassage 14, in-which is shown a strainer 15, while in the cover and casing is an outletpassa e 16. Between 'the passages and separate from'the outlet by a transverse wall 17 is a chamber 18.

About the top of the chamber in the inner edge of the extension and the wall is a recess adapted to'receive a flange 19, rojecting from the upper extremit of a sleeve or inner casing 20, which as ill ilstrated is cylindrical in form and extends downwardly through the chamber toward the inlet-passage. The cover- 12 rojects over the flange 19,where it rests in the extension recess and, being held in place by bolts 21, serves to normally maintaln the-sleeve in osition in the chamber. The upper edge of the sleeve extends inwardly at 22 and may have a portion cored out at 23 to effect reduction in weight.

device.

From the opposite end of the sleeve lugs 24- these openings are preferably inserted bushings 32, which may be of hard rubber and which have upon their adjacent ends flanges 33 extending over the bosses. At the lower portion of the recess 31 is a threaded opening 34, which receives a screw 35, having its inner end lying within the recess and which is preferably held against accidental rotation y a lock-nut 36. Supported upon the upp end of the screw within the recess is a be freely-movable member 37, furnishing a ste or thrust-bearing for a spindle 33, whic bears laterall upon the bushings. Between the arms of tlic spider 27 are shown 0 enings 39 into the recess adjacent to the en of the screw, these permitting a free flow of fluid through thebearin thus keeping it washed clean of particles w 'ch might produce wear. The u per end of the spindle is connected with t eregister-gearing by an arm 40, extending through a lateral opening in the spindle and held in place therein by a setscrew 41.

The spindle carries a wheel or measuring This as illustrated comprises a sleeve 42, fixed to the spindle and provided with a flan e 43, which may contact with the upper bushing and at its opposite extremity with a flange 44 of greater diameter than its companion and to which is attached a head 45. Projecting upwardly from the head near its periphery 1s a circumferential series of vanes 46, lying substantially parallel to the spindle and inclined with respect to radii from the axis of the wheel. Connecting the vanes at their upper ends is shown a ring 47, and this, to ether with the vanes and head, are referab y ofhard rubber. The diameter oft e wheel is such that a considerable space -;is left at 48 between it and the inclosing sleeve, this being substantially closed near its upper end by the ortion 22, which extends 1nto proximity wlth the rin 47.

(The boss of the spider 26 may e threaded inlet-passage and rises between the arms of' the spider 27 into the space 48, surrounding the wheel. The current now passes through the spaces between the vanes in directions substantially radial to the axis, it being directed by the portion 22 of the casing, exerting a force against their inclined faces which causes the wheel to rotate in its bearings. This movement is communicated to the register by the spindle and arm to indicate the quantity of fluid flowing. After its passage between the vanes the fluid continues its radial travel until it strikes the deflector, which causes it to move substantially parallel to the axis between the arms of the spider 26 into the outlet-passage. Upon a cessation of the fluidflow the rotation of the wheel is promptly stopped to prevent racing or over-registration through the resistance exerted by the vanes and the wings 53 against the'fluid. The efliciency of thewings is increased by their position at the inlet side of the wheel. Here the fluid enters the chamber in a direction parallel to the axis and is ractically unefiected by the movement 0 the wheel, which causes the fluid at the outlet side to rotate with it and to tend to continue in motion after flow has stopped. Consequently these wings act in a substantially immobile body, furnishing a maximum resistance. It should be noted, however, that by dispensing with the customary fixed and inclined directing or reaction vanes and allowing the fluid upon both sides of the wheel-vanes to move in right lines such swirling or rotary currents are largely eliminated, they arising only from the travel of the wheel itself. Moreover, the omission of these elements and the providing instead of ample spaces at both sides of the vanes renders it impossible for entering solids to clog or break the wheel.

As the fluid rises a ainst the under side of the head it tends to ift the wheel, and thus relieve the ball from the weight of the rotating parts. The fluid which exerts this lifting force transmits its pressure throu h the openings 52 to the upper side of the ead, practically balancing it, and this allows the upward pressure to be reduced to the desired extent, preventing a transference of the thrust to the upper bearing.

It will be seen that my improved arrangement of separable sleevesupporting the measuring device and being held in place in the casing by the cover renders it possible upon the removal of the latter element to withdraw the sleeve and measuring device together. This having been done all parts may be readily seen and maybe disassembled without the danger of injury which exists when unskilled persons attempt to take out elements independently secured within the casi and to a greater or less extent concealii Having thus described my invention, I claim 4 1.
