No. 193,474, Patentd July 24,1877.
WITNESSES.-
INVENTOR 6 7 M ww 7d UNITED STATES PATE 1 1* OFFICE.
FRANK BOYD, OF OSHKOSH, WISCONSIN.
IMPROVEMENT IN PNEUMATIC SIGNALS.
Specification forming part of Letters Patent No. 193,474, dated July 24, 1877; application filed July 3, 1877.
To all whom it may concern.-
Be it known that I, FRANK BOYD, of Oshkosh, Winnebago county, Wisconsin, have invented certain new and useful Improvements in Pneumatic Alarms or Signals, of which the following is a clear, full, and exact description, reference being bad to the accompanying drawings, making a part of this specification, in which Figure 1 is a side view. tudinal section.
This invention relates to improvements in pneumatic alarms or signals, the object being to make a simple apparatus or alarm for hand use on sailing vessels, for farm use, 850. and the invention consists in the general construc tion and arrangement of an air-pump, with a whistle or vibrator attached thereto, as will be hereinafter fully described.
In the drawings, A represents a metal tube or pump cylinder, supported horizon tally upon legs a, which are provided with holes a, whereby the cylinder can be secured upon the deck of a vessel or other convenient place. B represents a piston fitting and playing within said tube or cylinder A, and 0 represents the piston-rod fitting and passing through the perforated head D of the tube or cylinder, and E the handle of the piston-rod. F is a valve placed in the lower end of said tube or cylinder, and in front of the perforated head D. This valve admits the air to the cylinder, and is opened by pushing the piston-rod and piston forward, and is closed by the pressure of the air when the piston is drawn backward.
Fig. 2 is a longi- G is a pipe or tube communicating with the tube or cylinder near its lower and air-inlet end, and to this pipe or tube G is fastened the screw-threaded end of a hollow spindle,
of whistles given) the apparatus may be madeuseful for different purposes.
I am aware that various forms of pneumatic signals or alarms, consisting of an air-pump and a whistle or vibrator, are old, and such I do not claim, broadly, as my invention; but
What I claim as new, and desire to secure by Letters Patent, is-
The herein-described pneumatic signal, consisting of the tube or cylinder A, having the perforated head D and valve F arranged in one end thereof, the piston B, piston-rod O, and whistle or vibrator K I b, the several parts constructed and relatively arranged as specified.
FRANK BOYD.
