IMPROVEMENT-1N Low-WATER INDICATORS.

TO ALL WHOM IT` MAY CONCERN:
Be it known that I, L. FRANKLIN SMITH, oi' the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Low-Water Indicators; and I do hereby declare that thc following is afull and exact description thereof, reference being had to the accompanying drawings,and. to-the letters of reference mnrkedthereon. l p I v The nature of my invention mainly'consistsinthe arrangement of a water-gauge and three-way cocks in relation to the boiler, and with reference to an expanding tube, which operates an alarm, as represent'edin the following description. In the accompanying drawings- I Figure 1 represents a front elevation of the improved apparatus.
Figure 2 is a vertical section of the same at the red line 1 2 of iig. 1.
Like letters in both the figures indicate the same parts. i
A. is a short pipe, which communicateswith the water in lthe boiler, below the water-line at one end, and at the other end with ythe T-tting B, which is connected with the brass expanding-tube Gby means of the short pipe D and fitting E. The said tube, by means of'its connection with the boiler?, as described, is illed with water when the same is above the water-line; but when the surface has descended below the waterline, the
water in the'tube descends into the boiler, and steam takes its place, and the heat thereof` expands the tube and throws the short end of the lever F upwards, the lever having its fulcrum-pin a through theA cheeks b b of the connecting-head c ofthe vertical steel rod G, whose-lower end passes through'the plate d ofthe tting E, and is provided with nuts e e for adjusting the fulcrum-'pin 11. In the ascent ofthe short arm of thelevcr, the long end bearing on thc front end of the weighted lever H, whose fulcrum-pin f is supported in the cheeks g of the arm t, on the upper end of the stem I of the whistle J, the vertical rod z of the valve K is borne-down far enough to open the valve for the escape of the ste Ain to. blow the whistle, the steam from the boiler passing up from the base-bowl L, which communicates with the upper part of the boiler by means of the three-way cock M. On the back end of the lever there is a weight,.N, which closes the valve. O is a glass tube, which con stitutes the water-gauge. -`I ts upper end is confined in the chamber P, and its lower end in the chamber P', which has communication with the water in the boiler by means of its connection with the T-iitting B, through the three-way cock Q, and the passage R, in the series of connecting pipes between said cock and the fitting.
The cock Q answers the double purpose of opening and closing the communication between the boiler and the water-gauge. The three-way cock M answers the double purpose of opening and closing the communication between the whistle and the boiler and the water-gauge, separately and conjointly. The whistle may be used for the common purpose of a call-whistle byattaching a rod or cord to the front end ci' the lever H. The steell or iron rod G may be placed on either side of the expanding-tube C.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The arrangement of the water-gauge O, chambers P and P', and three-way cocks M and Q, in relation to the boiler, and with reference to tho expanding-tube C and lfixed rod G, substantially as described, and for the purposes specified.
f 2. The arrangement of the weight N, with the lever H and arm t for closing the valve K, substantially as described. 4 In testimony that the above ismy invention, I have hereunto set my hand and ailixed my seal this 25th day of February, 1867.
