IMPROVEMENT IN METERS.

Sperjicatioit forming part of Letters Patent No. 68,746, dated September 10,1867 reissue No. 4,206; dated December 20, 1870.

To all whom 'it may concern Be it known that we, J Aeon G. HoRToN, of the city', county, and State of New York, and SAMUEL K. HAwKINs, of Lansingburg, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Liquid and Fluid Meters, and in the method of operating valves; and we do hereby declare that the following is a lull, clear, and exact description thcreof, snfti cient to enable those skilled in the art to which our invention appertains to make and use the same, reference being had to the accompany-- ing drawings making part of this specification, and to the letters and figures marked thereon.

Oui' invention relates to certain improve ments on that for which Letters Patent of the United States were granted to us bearing' date April 2, 1.867; and it consists in the peculiar construction and operation of parts as hereinafter particularly referred to.

In the drawings, Figure 1, Sheet l, is a plan view of our improved meter, the cylinder-heads being removed and the mechanism below the cylinder shown in dotted lines. Fig. 2, Sheet 2, is a vertical section through the center of the measuring-cylinder, one of the heads being removed. Fig. 3, Sheet 3, is an elevation ot' the front end of the meter. Fig. 4, Sheet 4, is a sectional view, showing one of the valves, with-the valve-seat, induction and eduction and cylinder-head,Y Fig. 5, Sheet 4, is a :s view of the bracket which connects V .piston-rod with the reciprocating frame and plate underneath the cylinder.

The meter stands upon legs A A, which may be cast solid with thel cylinder. The measuring-cylinder B B is made of cast-iron, and lined with brass. C is the piston, and G' the piston-rod. B' is the front head of the D is a dialcase for containing a dial-face and registering-index. (Not'shown in the drawings.) E is a reciprocating frame, located underneath the cylinder, and carried to and fro by the piston-rod, by means of the connecting-bracket E attached ,to the front end of the piston-rod. F is a skeleton plate connecting the two side bars of the frame E, and having in its upper side two grooves, g

and g'. (Shown by dotted lines in Fig. l, but

more distinctly in cross-section in Fig. 3.)

The induction-pipe G Gr (the internal diameter of which is shown by dotted lilies a. b, Fig.

A1) branches at the induction port G', and runs to each end ofthe cylinder, where it connects with continuation cross-pipes, one of which is shown at G, Fig. 4.

The eduction pipe H H (shown by dotted lines a. b, Fig. 1) branches at the eduction-port H,and connects with continuation crosspipes in the cylinder-heads, like the induction-pipe, one of which said continuation cross-pipes is shown at H in Fig. 4.

Theside induction and eduction pipes are cast on and with the cylinder, and the cross pipes are cast on and with the cylinder-heads, so that when the cylinder-heads are in place the side and cross pipes unite and become continuous.

At each end of the cylinder there is a conical oscillating valve, V, which is hollow, and has an opening or slot, V', to admit water or other liquid or fluid into. the cylinders through the induction-pipe G, or out through ednctionpipe H, as said slot coincides with one or the other of said pipes. S, Fig. 4, is the valvestem, and p p the packing. A precisely similar valve, with the same arrangement ol' pipes, stem, 'and packing, is connected with the opposite cylinder-head.

The piston-rod moves in a stuing-box, I, Fig. 3, inthe front cylinder-head, but does not pass through the rear cylinder-head.'

To the outer end of each valve-stem an arm, J, is rigidly aixed, extending downward at right angles with. the valve-stems. These arms J are connected together at their lower ends by a bar, K, Fig. 2; but neither the valve nor the arm J is shown at the rear end of the cylinder in the drawing.

A stud, K', is fixed in the center of the bar K, and projects down into groove g or g', according as said stud may be thrown to the right or left by .the means hereinafter described.

Two levers, l and l', are pivoted to the side bars of the reciprocating frame E, (on the np-` per side thereof,) at i and i. The pivots pass through said side bars, under which are two transverse levers, yn and n', attached to the lower ends of said pivots 'i and i', both the upper and lower levers being rigidly attached to the pivots, which turn in said side bars, thus forming bent levers turning ou their fulcra 'i and 'i'. The ends of said transverse levers n and n' are connected by a spiral spring, m, (shown clearly in Fig. 2,) which tends to strain the ends of said levers toward each other.

The slots V' in the valves V are on opposite sides of said valves, so that (the valves oscillating together) when the slot at the front end coincides with the induction-pipe G that at the rear end coincides with the eduction-pipe H, and vice versa.

The operation is as follows: When the pistou is movin-g from the rear end to the front end of the cylinder, the stud K' is in thc groove g of the reciprocating plate F, holding the valves in such position that the slot in the rear-end valve coincides with induction-pipe G, while eduction-pipe H, at the same end, is closed; but at the same time induction-pipe G at the front end is closed, and eductionpipe H at the same end is open. The liquid (under suicient pressure) is therefore forced into the rear end of the cylinder through the inductionpipe and valve, moving the piston toward the front end of the cylinder, and forcing the liquid'out of said front end through the valve and eductiou-pipe. When the piston has reached the extreme front end of the cylinder, the rear end of reciprocating plate F'has passed the stud K', which, 'being disengaged from the groove g, is suddenly thrown by the lever l, actuated h v the spiral spring m, across the end' of plate F, until arrested by a ledge in linewith the outer edge of groove g. This causes both valve-stems so far to oseillate as to reverse the valve-ports, bringing the slot in the front-end valve to coincide with the induction-pipe, and closing the eduction-pipe at that end. while at the rear end the induction-pipe is closed and the eduction-pipe is opened at the same instant. As soon as said valves are reversed the pressure ou the front side of the piston causes it to reverse its motion automatically and travel back toward the rear end of the cylinder, the stud K' taking the groove and when it reaches that point, as shown in Fig. 2,' the lever l', pressing upon the stud K', throws it back to groove g, and so the reciprocatng motion of the piston is automatically kept up, and at each stroke of the piston the contents of the measurin g-cylinder are discharged in uniform quantities. Thev reciproeating frame E slides in V-shaped grooves in the legs of the machine, as shown at r r, Fig. 2.

An index, to be operated by familiar mechanism, which will suggest itself to any competent mechanic, should be attached, to indicate on a dial-plate the strokes ot' the piston. The meter is intended to operate under a pressure of about two pounds to the square inch, more or less.

What we claim as new, and desire to secure by Letters Patent, is-

1. A valve or valves for liquid meters and other purposes, moved instantaneously at the extremity of the travel of the piston by mean-s of power accumulated during the travel of saidpiston, substantially as shown and described.

2. The reciprocating grooved plate F, in combination with the oscillating valves, the arms J, bar K, stud K', and the spring and levers by which said stud is thrown from one groove to the other, substantially as shown and described.

3. The reciprocating grooved plate F, in combination with the stud K' and the levers and spring by which said stud is thrown from one groove to the other, as a means of operating oscillating valves, substantially as shown and described.
