'and ALBERT G: CHRIsTOPIiERsON, citizens of the United States of America, residing, re-
-s ectively, at Whiting, in the county of onona and State of Iowa, and at Scribner, in the county of Dodge and- State of Ne braska, `have invented new and usefiil Improvements in Telegraph-Sounders, of which the following is a specification.
This invention relates to telegraphic sounding instruments, and it has for its objects to simplify and improve the construcvtion and O eration of this class 'of devices.
A s )ecia object of the invention is to enable tie telegraphic sounding apparatus to be efficiently o erated with the least possible expenditure ci) electrical energy, and'especially without the use of locaI batteries; a permanent #ma vthe latter, as will be hereinafter described.
With these and other ends in view which vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinaftenfully described, and particularly pointedI out lin' the claims.
In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being, however, Aunderstood that no limitation isl necessarily made to theprecise structural details therein exhibited, ut that changes, alterations and modifications within thescope of the invention may be resorted to, when desired.
In the vdrawings:----1.`igure I-'is a top plan view of a telegra h -sounder constructedin accordance with t ie principles of the inven-y tion. 'Fig. Buis asideelevation of the same.
A suitable base, 1 'is .provided with uprights, 2, 2, supporting a permanentmagnet Pivotally'mounted upon the base, in iront of the permanent magnet, is a lever, 4, carrying an electro-magnet, -5`,' the winding of' which is includedin the line circuit. id
