IMPROVED SAFETY APPARATUS FOR GAS-MACHINES AND CARBURETERS.

Specification forming part of Letters Patent No. 58,055, dated September 18, 1866.

To all whom it. may concern:

Be it known that I, JOHN F. BOYNTON, of

with atmospheric air and explosive gases, of

which the following is a specification.

It is well known that when hydrocarbon vapors are mixed with certain proportions of atmospheric air an explosive mixture isformed, from which serious damages may result. In cases where hydrocarbon liquids are used for carburetin g gas or air explosive mixtures are liable to be formed, and the flame may pass. back through the gas pipe into the reservoir and produce an explosion. It has long been known that the flame of burning gas may be extinguished by close contact with metal or other good conductor of heat. It is on this principle that the miners or Davys safetylamp is constructed. Safety oil-cans are also made on this principle.

Now, my invention consists in interposing, in a gas-pipe, between the burner and the carbureter or oil-reservoir a safety device, or enlargement of the pipes, which will arrest the flame in passing up the pipe from the point of ignition. This device consists in dividing up the channel in any'convenient manner, so as to extinguish the flame by bringing it in contact with alarge surface of 'cold metal or other good conductor or absorbent of heat.

The following drawing will explain the device: A,the entering-pipe; B,the exit; O,tl1e lower convex surface; D, the upper convex surface; E, the one or more perforated plates of metal F, a section of circular disk separating the plates; G G, the upper and lower diaphragms; H, the space occupied by the fragments of metal, or their equivalents; I I, thc space between plates.

' Instead of the arrangement above shown, an enlarged, cavity in the pipe filled with shot, metal filings, nails, scraps ofmetal, sand, 800., will extinguish flame by suddenly absorbing heat from it.

cut is stated in the following claim, to wit:

A safety device composed of a body of cooling material, as metal or other good conductor of heat, interposed between the burner and carbnreter, and so arranged as to present an extensive surface or series of surfaces to the carbureted air on its passage to the burner, thereby keeping it at a temperature below the point of ignition.
