Description

@anni (time n rJOHN F. HASKINS, 0F FITCHBURG, MASSACHUSETTS.
Leners Patent No. 110,o36,'tea December 13,1870.
IMPROVEMENT IN NAUTlCAL A'LARMS.
The Schedule referred to in these Letters I Patent and making part of the lame.
To allwhom it 'may concern..-
ing a fog, for police use, for alarms by private watch'-A lueu-aml families, for signals and alarms by track-repairels and othels connected with railroads, 85e.
1t consists in the combination `of an air-condensing pump withinan air-reservoir, and a whistle or. other device capable of emitting loud sounds, produced by vibrations caused by escape of a currentot'compressed air, the elements-of the combination being arranged so as to make aportable whole, in which by relative movement between the compressing piston and airrcceiverfair is compressed and stowed in the receiver in readiness to sound an alarm or signal whenever, by operating a cock or valve, the whole or a portion of the compressed and stored air is allowed to escape,
`and is directed upon any suitable attached vibrator.
An embodiment of this invention is illustrated in -the drawing, which is a central longitudinal section of my improved apparatus, showing theA parts beyond the sectional plane in elevation.
a is a receiver, made air-tight, of strong thin metal, and containing an air-pump, like one described in detail in the specificationand drawing of an application for United States Letters Patent, executed by me September 24, 1870, said pump having its longitudinal axis in'the longitudinal axis of the receiver a.
The receiver is provided at itstop with a handle, b, by which it may be conveniently carried.
The piston of theairpump is provided with a pistonrod, to the end of which a loop or stirrup c is tixed,so that when a person places one foot in the stirrup the operation of working thepump to compress air into the receiver ,may be performed by moving the receiver up and down, by means of the handle b, until air shall be condensed in the receiver to any required degree.
While I have shown at the right of the drawing a common whistle, such as is used for producing sounds by currents of steam ordinarily, and a common cock for controlling communication between the whistle and the reservoir a, it will be obvious that other forms of vibrators and valves or cocks might be employed.
' The form of the receiver is not materia-l, so hing-as it contains the air-pump, and is portable; for example, the ilagstai' of a signal-man may be the receiver-,
means for controlling the passage between it and the reservoir, arranged as shown, and for the purposeset forth.
