UNITED STATES PATENT OFFICE.
PEDER OLUF PEDERSEN, OF COPENHAGEN, DENMARK, ASSIGNOR TO AMERICAN TELEGRAPHONE COMPANY, A CORPORATION OF THE DISTRICT OF COLUMBIA.
MAGNETIZABLE BODY FOR THE MAGNETIC RECORD OF SPEECH, &c.
Specification of Lettersv Patent.
Patented Nov. 20, 1900.
Application filed June 21,1901. Serial No. 65,421.
which surface is of material capable of being magnetized and of retaining its magnetism.
The invention is s eciall useful as the recording body in'a te egrap one, because the electrolytically-pmcipitated material is uniform in thickness, and for other reasons also it is especially adapted for said purpose.
In carrying out the invention I may use a core or base of brass, cop er, iron, or any other suitable material, and upon this I elec- 5 troplate a surface of steel, nickel,- or other magnetizable material capable of retaining it s magnetism. When a body thus plated is I used in a telegra hone, the recordin -magnet is presented to t e electrodeposited layer and the magnetic variations of the magnet are imparted to said layer and retained by it for repgoduction whenever desired.
. he accompanying drawings show in Figure 1 a sectional perspective of the record-receiving body of the telegraphone in the form of a disk; Flg. 2, a similar view of such body View of such a body in the form of a cylinder.
a indicates the body or core of the device, and b the electroplating of magnetic mate- 'rial thereon.
Havingdescribed my invention, I claim- A recording-body for telegraphones consisting of a suitable core or base having an electrodeposited even surface of magnetic material adapted to record magnetic impressions representing sounds or signals.
' In testimony whereof I have hereunto set my hand in the presence of two witnesses.
