IMPROVEMENT IN'eAs-REGULAToRs.

Specilication forming part of Letters Patent No. 178, [34, dated May 30, 1876; application filed i May 26, 1876.

To all whom lit may concern:

Be it known that I, GEORGE W.` HAM- BRIGHT, ot' Washington, District of Columbia, have invented a new and useful Improvement in Gas-Regulators; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a perspective View of the improved device, detached from the pipe 5 and Fig. 2 is a longitudinal section of the apparatus placed within the pipe, as it would he Similar letters of reference in the accompanying drawings denote the same parts.

My invention relates to an apparatus for regulating the flow of illuminatinggas in house-pipes; and has for its purpose particularly the prevention of what is called blowing, whereby the gas is wasted, and the meter is made to 'misrepresent the amount of gas consumed. It consists more particularly of a diaphragm tted to be placed at any 'desirable point in the pipe.

The device in which I have embodied the invention is of very simple construction. It consists of an outer ring or section of tube of a diameter calculated to iit closely within the gas-pipe to which it is to be applied, and of length sufficient to hold the material used for the diaphragm. This diaphragm may consist of a simple piece ot woolen cloth, or any equivalent material, laid over the end of the short section of pipe, such as is shown in the drawing, and marked c. p A smaller and shorter piece of pipe, marked in the drawing I), is then placed over the cloth and driven in, carrying the cloth with it.

The inner pipe, it is obvious, should be of a diameter just sufficient to allow it tobe driven into place. It will hold the cloth across its inner end, tightly stretched like the headl the ordinary illuminating-gas can apply in their own pipe, before its connection with the meter of the company furnishing the gas, an effectual guard against the undue forcing of the gas before referred to. Obviously, the same device may be applied to any part of the pipe with beneficial effects either in the house or street pipes.

The action of the diaphragm is equally obvious. The texture is such as to permit a free percolation of the gas, but at the same time itV prevents any sudden gusts or blasts or excessive pressure calculated to set the meters in too rapid motion, or to force the gas too rapidly, and to waste it at the burners. I am aware that packing has been suggested for this general purpose, and that regulators, to be attached to the pipe, at the burner, or between sections of the pipe, have been before known. Snell, broadly, I do not claim.

The device which I have described is adapted to be placed within the ordinary gaspipe, leading from the meter, and has these advantages, that it can be made at a triiling cost, and sold as an article of manufacture, and can .be readily and easily applied by an ordinary workman, and, as there are no moving parts, and the whole is very simple, there is no liability to get ont of repair.

This regulator may be easily inserted and removed, since it is not necessary that it lit within the pipe `gas-tight. y

Any slight escape ofthe gaspast the short tube would not b e detrimental, or defeat the object of my invention.

If desired, a packing may be placed on the outside of the tube, torender more easy the insertion of the regulator in its place.

I claim as my invention- 1. A gas-regulator consisting of a suitable diaphragm, held in a rim` or ring, which is adapted to be placed within the ordinary gaspipe.

2. A gas-regulator consisting of a suitable diaphragm, held in a short section ot' tube, and adapted to be placed within the ordinary gas- Pllev 3. The gas-regulator composed ot' an inner and outer tube, with cloth or other suitable material held between them, as set forth.
