VALKER G. BROVNE, OF ATLANTA, GEORGIA, ASSIGNOR TO THE UNITED STATES AUTOMATIC VATER OUT-OFF COMPANY.
AUTOMATIC CUT-OFF VALVE.
SPECIFICATION forming part of Letters Patent No. 360,140I dated March 29, 1887.
(No model.)
To @ZZ whom it may concern:
Be it known that I, TALKER G. BnowNE, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of 5 Georgia, have invented a new and useful Automatic Gut- Off Valve; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper- Io tains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures oi' reference marked thereon, which form a part of this specification.
This invention relates to the class of thermal i5 valves that are closed automatically by the torsional motion of a compound coil that is composed of two metals having different expansive properties, the compound coil being actuated by a change of temperature, the b- 2o ject being to prevent the freezing of waterpipes by shutting off the supply on the approach of the freezing degree of temperature; and it consists of a valve having a weighted lever in suspense, which is released and al- 25 lowed to fall at the desired temperature by the action of a compound coil, as will be hereinafter fully described.
In the accompanying drawings, Figure I is a side view showing the valve, its weighted 3o lever, and the suspending device. Fig. II is an end view showing the same. Fig. III is an end view somewhat enlarged of the weighted lever and suspendingcatch. Fig. IV is a side view ofthe same, being all in longitudinal 3 5 vertical section except the catch. Fig. V is a side view of the casing that contains the co1npound coil and forms the weight and the end of the sustaining'catch, showing the catch reversed. Fig. VI is a section oi' the compound 4o coil.
In these gures like reference-marks referto like parts.
1 is a valve, which is provided with an actuating-lever, 2, on the outer end of and at- 45 tached to which is a hollow weight, 3. This hollow weight is firmly attached to the larger part of the valve-lever 2, and runs freely on thejournal 4 at its end; also firmly attached to the valve-lever is the compound coil (3 7.
The other end of the compound coil has a lng, 5o 8, attached by the plate 9, which extends outwardly a sufficient distance to engage the catch 10. The plate 9 is journaled on the lever and keeps the free end ot the coil in a definite position. The relative positions ofthe catch 10 55 and the weight that incioses the compound coil are governed by the guiding-hooks 12. The catch 10 is pivoted to and suspended from the ring 14. The ring 14 slides on the rod 15, and is adjusted thereon by the nuts 16 and 17. 6o The rod projects from the bracket 19, which is preferably attached to the pipe by the sleeve 20.
The compound coil is composed of a metal having a high expansive quality, preferably brass, and a metal having a low expansive quality, preferably steel, one of which is wound over and bran/ed or otherwise fastened to the other, asshown in Figs. IV and VI.
Figs. I, II, and IV show theoperative parts 7o in the position in which they are when the valve is open. It will be observed that when in this position the lng on the end of the conipound coil rests on the top of the catch 10, and sustains the lever in a horizontal position, and that to release this lever would allow it to close the valve by falling to a Vertical position, which will occur whenever a change in the temperature shall, by its effect on the two different metals, have produced a sufficient tor- 8o sional movement of the free end of the coil to carry the lug oft' of the catch, which will release the lever.
It is my intention to have the upper face of the catch, on which the lug 8 rests, of sufficient 85 width to prevent the lug` being slipped off of the catch by any natural heat when set to release the weight at any desirable degree of cold. The catch is made with a curved head, the radius of curvature of which being from 9o the center of revolution of the valve-lever and slide within, and is controlled laterally by the guiding-hooks 12, in order that it maybe held with certainty in its position and allow the guiding-hooks to pass over nearly its whole length, when it shall be necessary to lock the valve open by raising the weight until the top end of the catch will enter between the guiding-hooks 12, which will pass over it nearly its -entire length. The face of the catch, against which the lng 8 bears, is curved to the circle described by the lug, and both ends of the catch are made alike in order that the catch may be reversed, as shown in Fig. V, to accommodate the device to the positions in which it is desirable to have the bracket 19 project downwardly.
rIhe bracket may be attached to a vertical pipe or other object so long, and it suspends, as described, the weighted valvelever in a horizontal position.
It is obviously necessary to adjust the releasing mechanism to allow the lever to drop at the desired temperature, which I- do by changing the position of the ring to which the hook is pivoted by the nuts 16 and 17, thereby changing the relative position of the catch to the lug 8.
As more power is needed to start the lever than to carry it after being started, I make the hole through the lever larger than that part of the valvestem to which it is attached, as shown in Fig. I, for the purpose of allowing thc weight to drop slightly and engage with the .valvestem after having acquired eXtra force by its momentum'.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. In an automatic cut-oft' valve, the combination of the valve, its actuating-lever, a compound thermostatic coil having a lug on its iree end, a weight encircling said coil to actuate the lever, and a restraining-catch operated by said coil, substantially as set forth.
2. In an automatic cutoff valve, the combination of avalve having a weighted actuatinglever carrying a compound coil having a lug on its free end and a restraining-catch, and means of adjustment consisting of the ring 14 and nuts 16 and 17, substantially as described.
In testimony' whereof I afx iny signatureiu presence of two witnesses.
XVALKER G. BROWNE.
