I/MPROVEMENT IN `MOULDS FOR CASTING THE CYLINDERS AND DIAL-BOXES OF l WATER-METERS.

The Schedule referred to iu these Letters Patent: and making part f the same.

To all whom. 'it may concern Be it known that I, HENRY F. READ, ot' the cityV of Brooklyn, in the county of Kings, and State of New York, have invented Improved Moulds for Casting the Cylinders and Dial-Boxes of Tater-Meters; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference heilig had to the accompanying drawings, and to the letters of reference marked thereon.

The. nature of my invention consists in so constructing -the moulds that the'cylinder and the body of a dialhox niayhe cast in them in one piece, with-'all the necessary parts, such as slots,'screwthreads, internal as wellas external, except thecap, which, with all-its parts, is also cast in another single piece, s o that when the castingis done, the work is done, with the'exception of the making of the screw-bolts by which the cap is fastened upon the dial-boit.

To enabie others skilled iu the art to Inake and use my invention, I will proceedto describe the saine.

In the drawings- Figure 1 represents an inner-side vview oI' one-half the inould, with the core, or mandrel lying in position, and p 1 `iguref2,'au upper-end yiew ofthe same.

Figure 3 represents an inner view of the other half ot' the mould, and l Figure 4, an upper-end view thereof.

Figure represents a side view ofthe cylinder and dial-box, after heilig cast, andv Figure 6, an end view thereof.

'Figure 7 represents an inside view of one-halt' the mould for the cap, and

Figure 8, an edge or cndwiew of the same. FigurcJ reprcsentsan inside viednrotxthe other half,- and y Figure 10,1111 edge view of the same, with the cappiece Q in position.

Figure 1l represents-a top viewof the cap I (when cast) ot' the dialfhox, and 1 Figure 12, an edgefviewof the same. A

I will first giro a general'description-of the parts to he cast, and their uses, before describing the moulds into which-they are to hecast.

In iig. 5, A is the cylinder through which the water to be measured passes iom the supply-pipe, and a' a. are the convex screw-threads formed on the ends thereof, by' which theI ends are connected with the supply-pipe.

p -is a longitudinal slot through the neck of the dialbox into the cylinder; and in this slot the driving-wheelrevolves, and communicates the motion which it re ceives from the Water-wheel to the indicating-apparatus, to be contained in the interior b of the dial-box B.

g' is another slot, ruiming at right angles to the slot h' in the neck of the dial-box; and through it a shaft is to pass from the driving-wheel, to communicate mo- `tion therefrom to the apparatus in the interior.

'The dial-box B is formed with a wide, strong flange,

corresponding with the neck of the box, and with a wheel-house, R,whicli, when the cap is in position, furnishes the necessaryadditional space for the driving-wheel before mentioned. f

These flanges lon -the dial-box and iu the cap, and the holes through both, and the threads in the holes iu the ange of the dial-borgate simply for the purf v vpose of securely fastening the twoparts together, by

' means ot' screw-bolts.

As shown in fig.'11, the cap has a large circular opening in its top, which is dared, to admit the rays of light upon lthe dial-plate, and this opening is iutended to receive a glass through which the indicators may beseen. l 4

The inside of the top ot' the cap is furnished with a bead, or projecting rim, against which the glass from the interior may abut.

These two' parts-the dial-box and cap-may be cast of white metal, o r any other suitable metal, as I. claimno noveltyv in the material to be used.

I will now describe the moulds for casting the part-s above described. The moulds for the cylinder and dial-box are composed ofthe two parts, C and F, in figs. 1 and 3, and the mandrel D. The part C gives form to the exterior of the dialhox, and, with the aid of lthe mandrel, to one-half of the cylinder, while the part F gives fornito the iutelior of the dial-box, and, with the aid of the mandrel, to the other half ofthe cylinderthe cores h and g forming the slots hf and g in the dialbox and cylinder.

no, iig., 1, are .piu-holes through the flange, and e' c are pins onv the iauge of part F, to fit into these holes, and act as guides, and hold the two parts in their true position when casts are'made. In each part is one-half of the gate E, by which the molten metal is conducted into thc mould.

` The mandrel, at the lower end, is provided with a 6, and this flange, as well as the neck of the circular collar, c, which lls that end of the mould, and stops the flow of the metal, and thus forms the lower end of thecylinder; and just above this collar' the movable collar d, serves to hold the mandrel in its proper central position, -so that the metal will ilow around it, and form the cylinder. l

'lhe elevation d performs a similar office' to that performed by c'.

The female-screw threads a a out in the mould form the male threads a' a upon the cylinder, as shown in tig. 5.

The collar d is made -to slip over tue end of the mandrel, and is removable, so that the mandrel may be withdrawn from the cylinder A after the cast is made. -i

The letters f indicate the ends of the set-screws, which, when a cast is made, extend through the holes, which are provided with `feInale-screw threads in the flange of the part F, as shown in iig. 4, to impinge upon the other half of the ,mould O, and the molten metal flows around their male threads,and forms the female threads in the holes marked f' in the dial-box, as shown in fig.j 5. When the cast is made, the setsbrews f are merely turned backward, and thus withdrawn, leaving the female-screw threads completely formed. Y

I will next describe tlie'nlould for the cap P, shown iu figs. 11 and 12.

The form of the part L is shown in figs. 7 and 8.

E indicates one-half of the gate by which the melted metal is admitted; t', the core upon which is formed the interior of the wheel-house It, in the cap P, figs. 11 and 12; and theletter j indicates the corepins upon which are formed the plain holes marked s, in fig..l1, in the cap; and G is the core upon which is formed the opening in the cap, to lafford space for the glass before mentioned; and :v isa guide-pin, and ts into hole x when the parts are together.

The other and counterpart K, in figs. 9 and 10, has a corresponding form. 'A disk, the outline of' which is indicated in part by the dotted line lw, is detachaf ble, and co-operates in giving thedesired flare and bead in the interior upperpart of the cap before described.

The core i forms the outline of the wheel-house R. shown in figs. 11 and 12.l

It will appear from the foregoing description, that dial-boxes and cylinders will come tiom moulds constructed according to my invention perfect and ready for immediate use, withthe single exception of the screw-bolts.

As the whole is cast,there must be perfect uniformity in the size and proportion of parts, so that vlittle time or labor need be expended in ttingthe in terior works into them.

It is obvious, too, that the use of my invention will greatly conduce to the cheap and rapid manufacture of water-meters.

What I claim as new, and desire to secureby Let ters Patent, isi- 1. The mould for ythe cylinder and dial-box, composed of parts G and F, and the mandrel D, with its -removable collar d, when constructed substantially as' y and for the purpose described.

2. The mould for the cap of the dial-box, composed of the parts L, Q, and K ,`constructed substantially as and for the purpose described.

3. The cylinder A and dial-box B and cap P, when cast in metallic moulds, constructed substantially as described and substantially in the manner described, as a new article of manufacture.
