AUGUST F. BAATZ, OF BELLINGHAM, WASHINGTON TERRITORY.

AUTOMATIC FOG -HORN.

SPECIFICATION forming part of Letters Patent No. 398,367, dated February 26, 1889.

Application filed April 11, 1887. Serial No. 234-439. (Nu modeh) To aZZ whom, it may concern:

Be it known that I, AUGUST F. BAATZ, of Bellingham, in the county of \VhatconnVVashington Territory, have invented a new and useful Improvement in Automatic Fog-Horns, of which the following is a full, clear, and exact description.

This invention relates to fog-horns for use in light-houses and elsewhere, in which the air to blow the horn is supplied under pressure from a reservoir charged by a pump operated by any suitable motive power, and in which means are provided for automatically keeping up an intermittent sounding of the horn.

The invention, which may be used wherever an audible signal in foggy weather is re quired, consists in a compressed-air apparatus of novel construction, in combination with the horn, and whereby the horn may be intermittently sounded without being controlled by clock-work, substantially as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 represents a longitudinal vertical section of my improved apparatus with foghorn attached, and Fig. 2 a plan of the same.

A is the compressed-air reservoir, which is supplied with air as required. If air of thirty pounds (30 lbs.) pressure is used to sound the horn every two, three, or five minutes, different-sized reservoirs will be needed.

B is a double-acting pump that may be operated when required by any suitable motive power, but preferably by a wind-mill where the location admits of such a driver being used, or said pump may be manually operated by a weighted working beam or lever.

C is a gage, which determines the pressure of air in the reservoir A, and which is only necessary when experimenting.

D is an automatic blow-off piston-like valve; E, its case, having spaces or chamber a b above and below the valve, and F is a weighted lever operating to close said valve, except when exposed to a superior pressure of air from the reservoir A, with which the space b of the case E is in open communication.

G is an air-chamber connecting by an aperture, c, with. the space a of the valve-box E. The object or purpose of this air-chamber G is to produce a longer sounding of the horn and to prevent the piston from closing too fast.

(l is a leakage aperture around the stem of the valve D, said stein being connected with the lever F in front of its fulcrum e.

H is the fog-horn, which may be fitted with any number of reeds, f, if desired, and which is connected at or near its lower or inner end by a pipe, 6, with the compressed-air reservoir A, for the purpose of discharging the air to and through the horn in order to produce the necessary signal or sound.

I a way-cock in the pipe 9 for opening and closing communication between the airreservoir A and the fog-horn H, and h is a rod or connection between the way-cock or lever thereon and the weighted lever F, which controls the way-cock.

J is a check-valvein the pipe i, which connects the air-pump B with the reservoir A.

The operation is as follows: When air has been forced by the pump into the reservoir-A till it acquires a given pressure, the blow-off valve D and weighted lever F will be raised and the way-cock I opened to blow the horn H. At the same time a certain quantity of compressed air will pass from the reservoir through'the space I) in the boX of the blow-off valve D and aperture 0 into the air-chamber G, and the valve will close the space a and leakageaperture (l, and air will be collected in said chamber G, the leakage-spaces being closed. This outward movement of the valve D will raise the lever F and open the way-cock I, and so sound the horn. This sounding of the horn will continue as long as there is a given pressure of air in the reservoir to produce the effect. If there is not sufficient pressure, the blow-off valve D, the weighted lever F, and the lever of the way-cock I will drop back to their places, and the air which isleft in the air-chamber G will escape into the outside air by the apertures or spaces (7', a, and d. The intermittent sounding of the horn .will take place according to the construction of the apparatus. If required to make achange,

the weight on the lever F maybe adjusted to give any desired working-pressure.

reservoir A and fog-horn H, connected there with, the valve-controlling piston D,with its box or casing and air-chamber G, said airchamber being provided with a connectingaperture, 0, above the piston-head, leakageaperture cl about the piston-rod, the weighted Va1ve-1ever F, attached to the piston-rod, the connection It between said lever and the waycoek I, and the way-cock I, essentially as and for the purpose herein sctforth.

'lhecombination of the compressed-air reservoir A, the pump B, connected therewith, the check-valve .I, located between the pump and reservoir, the valve-controllin piston D, with its easing E and air-chamber G, said airchamber being provided with a connectingaperture, (3, above the piston-head, leakage-aperture (I about the piston-rod, the weighted lever F, attached to and operated by the piston D, the fog-horn H, communicating with the air-reservoir through the pipe g, the waycoek I in said pipe, and the connection h between said way-cock and'lever, substantially as shown and described.
