Definitions
- My invention consists in an improvement in receiving-magnets for telegraphic and other purposes, set forth as follows:
- a A A2 is the electro-magnet; B B', the helices.
- the leg A2 of the magnet fills only a part of the bore of the helix, the remaining space being left for the vibrations of the permanent magnet a.
- This magnet is pivoted at its lower end, so that it may vibrate back and forth within the helix. Its polarity is such that when the electro-magnet is charged repulsion shall take place between it and the leg A2.
- In contact with the leg A is an adjustable piece of soft iron, C, the end of which is made to approach the magnet a and attract it, thus combining the repulsive and attractive forces in moving this magnet whenever the electrol magnet is charged.
- the position of the magnet a is regulated by the set-screwD, and the battery-connections are made in any of the modes commonly practiced with relay or receiving magnets.
- lVhat l claim as my improvement in receiving-magnets for telegraphs is- Opening and closing the circuit by means of a vibrating permanent magnet inclosed within one of the helices, together with an electromagnet, and operated upon by both poles of the electro-magnetin the manner herein set forth.

UNITED STATES PATENT OFFICE.
NATHANIEL PARKS, OF ROME, NEW YORK.
IMPROVED RECEIVING-MAGNET.
Specication forming part of Letters Patent No. 19,379, dated February 16, 1858.
To all whom t may concer-a:
Be it known that I, NATHANIEL PARKS, of Rome, in the county of Oneida and State of New York, have invented an Improvement in Receiving-Magnets 5 and .I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known, and of the usual manner of making, modifying, and using the same, reference being had to the annexed drawings, of which- Figure 2 represents a perspective view of the helices and electro-magnet 5 Fig. l, a lon gitudinal vertical section ofthe magnets, helices, &c.
My invention consists in an improvement in receiving-magnets for telegraphic and other purposes, set forth as follows:
A A A2 is the electro-magnet; B B', the helices. The leg A2 of the magnet fills only a part of the bore of the helix, the remaining space being left for the vibrations of the permanent magnet a. This magnet is pivoted at its lower end, so that it may vibrate back and forth within the helix. Its polarity is such that when the electro-magnet is charged repulsion shall take place between it and the leg A2. In contact with the leg A is an adjustable piece of soft iron, C, the end of which is made to approach the magnet a and attract it, thus combining the repulsive and attractive forces in moving this magnet whenever the electrol magnet is charged. The position of the magnet a is regulated by the set-screwD, and the battery-connections are made in any of the modes commonly practiced with relay or receiving magnets.
lVhat l claim as my improvement in receiving-magnets for telegraphs is- Opening and closing the circuit by means of a vibrating permanent magnet inclosed within one of the helices, together with an electromagnet, and operated upon by both poles of the electro-magnetin the manner herein set forth.
NATHANIEL PARKS.
