PATENT XATHAN C. BUTLER, LEIPSIC, OHIO.

AUTQMATIC WATER ALARM AND REGULATOR.

SPECIFICATION forming part of Letters Patent No. 278,872, dated June 5, 1883.

Application filed March 30, 18 83.

(No model.)

T0 66- u-hom, it may concern:

Be it known that I, NATHAN C. BUTLER, of Leipsic, in the county of Putnam and State of Ohio, have invented certain new and useful Improvements in. Automatic Water Alarms and Regulators for Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the invent-ion, which will enable others skilled in the art to which it appertai'ns to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an automatic water indicator and regulator for steam-boilers; and it consists in the parts which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a portion of the boiler with my device, partly in section, attached thereto. Fig. 2 is a horizontal sectional view of the device, showing the water-regulating parts, (section through line 00 w in Fig. 1.) Fig. 3 is a plan view of the. float. Fig. 4 is an end view thereof with a fragment of the float-lever attached. Fig. 5 is an inside end view of the water-regulating-valve stem, and Fig. 6 is a side view of the water-regulating valve.

Like letters indicate like parts throughout the several views.

A is a cap provided with threads which cngage the threads in the casing A. B is a recessed projection on casing r and formed integral therewith. O is also a projection on easing A, similar in construction to B. D is the inside of the casing, in which the steam and water valves are located. E is a plug having inside threads, by means of which the outside threads on casing A are engaged thereto. The lower end of plug E screws into boiler F. G is a block bolted to the inside of the boiler. H is a rod fixed at its upper end to block G, and pivoted at its lower end to lever Iii I is a rod connected at its lower end to the adjustable block J. L is the float, into which one end of the lever K is fixed. The rod I is adjustable on lever K by means of the sliding block J and set-screw 02, whereby the vertical play of rod I and valve 0 maybe regulated.

In the small letters, a is a locklever. b is an adjustable set-screw in the top of rod I. c is the pivoted end of lever a. Said lever is let in from the top, (in a dovetail, c,) and held in position by cap A. d is the watera'egulating valve. 0 is the alarm or whistle valve, and ff are the slides for the same. g g are nuts on rod 1, to secure valve 6 adjustably. h is a reeesson theinside of casing A, in which the point of lock-lever a rests. c is the alarm or steam-whistle port. j is the injector steamport. A: l are bolts for securing the block G to boiler F. I is the water-regulating-valve stein. m is a recess 01' mortise in the water-regulating valve (7. (See Fig. 6.) '11- is a set-screw in block J, for adjustably securing the same on lever K. 0, Fig. 2, is the flattened surface of valve-stem I. p is a bearing for valve-stem Z. (1 represents the parts upon which a wrench may be used. r is a bearing for valve (1. s is a movable stuning box, which secures the valve-stem Z, and t is the packing-nut. a rep resents the stuffingspacc. "u is a set-screw for securing lever 20 to rod 1. no is the opening, Fig. 3, in float L, into which the'lever K is fastened. 1 is a pin uniting rod H and lever K. 2 is also a pin, connecting block .I and rod I.

The operation of the device is as follows: hen the water in the boiler .gets low, the float L carries the float-lever K down, which draws down on the rod I and valve 6 and opens the alarm-port e, which permits the steam to enter the opening B, and thence into awhistle attached thereto, but not shown in the drawings. The whistle will notify the attendants of the condition of the water. Then by turning the lever 20 in Fig. 2, which is secured to stem 1, the valve (1 will be raised and secured by the lock-lever a, as shown by dotted lines, Fig. l. The injector is then set to work, and the water forced into the boiler through the openings 0, j, D, and 13.. As the wateriills in,

the float L is lifted, thereby raising the'lever K, rod I, and valve 6, and said valve, in rising, closes the port 6 and causes the whistle to stop blowing. The same upward movement forces the set-screw b on top of rod I intocontact with lever (1, whereby said lever is raised and the valve cl disengaged therefrom, which action permits the valve (1 to fall and close the injector-port j.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In an automatic water indicator and regulator for steam-boilers, the float L, lever K, rod I, valve 0, and setscrew b, in combination with the pivoted lever a and water-valve (Z, substantially as deseribed, and for the purposes set forth.

In an automatic \va-ter indicator and regulator for steam-boilers, the float L, lev'er K, block G, and rods H I, in combination with the valves 0 (Z and pivoted catch-lever a, substantially as deseribed, and for the purposes set forth.

3. 111 an autol'natie water indicator and regulator for steam-boilers, the float L, lever K, bloek G, and rods II I, in combination with the valves 0 (l, lever a, and easing A, prot'ided with ports ej, substantially as described, and for the purposes set forth.

4. 111 an automatic water indicator and regulator for steam-boilers, the float L, lever K, adjustable block J, boiler-block G, and rods H and I, in combination with the valves 0 (1, le

ver a, and easing A, substantially as des'eribed,
