TELEGRAPH RELAY AND SOUNDER.
SPECIFICATION forming part of Letters Patent No. 245,500, dated August 9, 1881,
Application filed June 20, 1881. (No model.)
To all whom it may concern:
Be it known that I, HENRY HOWSON, Jr., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Telegraph Relays and Sounders, of which the following is a specification.
My invention relates to certain improvements in the construction of the telegraphic instruments known as Morse sounders and relays,
the object of my invention being to provide a simple means of adjustment ofthe electro-magnet in relation to the armature.
In the accon'ipanying drawings, Figure l is a perspective view of my improved telegraphic instrument; Fig.2, a side view with the franc in section Fig. 3, a rear view; and Fig. 4, a view of a modification of the instrument when adapted to be used as a relay.
Referring to Figs. 1, 2, and 3, which show the instrument when adapted to be used as a sounder, A represents the armature, and M M the electro magnet. The electro-magnet in this instance is shown as composed of two coils or spools connected together at their bases by the cross-piecem. This cross-piece is provided with extensions m, which form pivots adapted to corresponding recesses or notches in lugs don the frame D of the instrument. The outer ends of these extension-pieces are threaded for the reception of screw-nuts d, by screwing which against washers in contact with the lugs 41 the magnet may be firmly secured in any position to which it may be adjusted, Fig. 2. The terminal wires of the coils of the electro'magnet are connected in the usual manner to suitable binding-stops, b b, on the base B.
The armature-lever has its conical pivotpoints supported in screws 6 e mounted in the yoke E on the upper part of the frame, and the extent of the vibrating movement of the armature is limited by the fixed stops to a on the base. The armature is moved in one direction by the attraction of the electro-magnet and in the other by a push-spring, (N, or in some cases the return movement of the armature, when released by the electro-magnet, may be accomplished simply by the gravity of the armature-lever, the positions of the stops to a in relation to a vertical line through the pivoting-point of the armature being properly arranged for that purpose.
The armature proper, instead of being a narrow strip of metal, as usual, is in the form of a plate of considerable width, and is curved to correspond with the are described by the extremities of the poles of the electro-magnet in moving the latter from one extreme point of adjustment to theother, as indicated by dotted lines in Fig.2. But the curve or are of the inner face of the armature, while preferably of nearly the same radius as the are described by the extremities of the poles of the electromagnet, is not drawn from the same center, but from a point eccentric to the pivoting point of the electro-magnet when the end of the armature bears against the stop a, so that when the electro-magnetis adjusted to the highestposition indicated by dotted lines in Fig. 2, with its poles neat est the fulcrum of the armature-lever, the said poles will be nearest the face of the armature; but as the poles of the magnet are adjusted farther away from the fulcrum, the distance between the said poles and that portion of the face of the armature directly opposite will be proportionately greater. By this means the distance between the poles of the electroanagnet and the face of the arma ture can be readily regulated to free the arm ature from the effects of the residual magnetism in the magnet, and by the same adjustment the distance of the point of attraction from the fulcrum of the lever is proportionately regu lated. Thus an increase in the distance between the poles and the face of the armature is compensated for by an increase in the distance of the point of attraction from the fulcrum, the adjustment being made, of course, without affecting the circuit-connections in any way. In the modification shown in Fig. 4 this double adjustment is obtainedin a similar manner by causing the electro-magnet to move over an inclined plane.
The under side of a bar or plate, 111, on the base of the spools M is beveled and adapted to guides on block it, having a correspondinglyinclined face. An adjusting screw rod, m turning in hearings on the block n, passes through a threaded opening in the bar or a projection on the bar at. By turning this regulating-screw the electro-magnet is adjusted so as to bring its poles nearer to or farther from the face of the armature A, and at the same time bring the point of attraction nearer to or farther from the fulcrum of the arm attire lever, the armature in this case, as in the instrument shown in Fig. 1, being elongated in respect to the poles in the direction of the line of adjustment.
In order to obtain the adjustment of the magnets in respect to the fulcrum of the armaturelever without reference to and independently of the adjustment toward and from the face of the armature proper, the block it maybe adapted to longitudinal guides on the base B, and be provided with a regulating screw, it, by which the block and electro-magnet may be adj usted in a longitudinal line with the armaturelever without changing the distance between the poles and the armature when the latter is under the attractive influence ofthe magnet.
The armature-lever in this case is shown as acted on by a push spring, (1?, and as the instrument is illustrated in this View to act as a relay the extent of vibration is more limited than in the case of the sounder, and the inner striking-face of the armature-leveris insulated, and has a projecting platinum tip to strike against a corresponding; tip on the stop at. These points are electrically connected with the binding-posts b for the local circuit.
It will be understood that the instrument shown in Figs. '1, 2, and 3 may be constructed so that the magnet may be adjusted, as in Fig. 4, in respect to the fulcrum of the armaturelever, without changing the distance between the poles of the magnet and the face of the armature by mounting the hearings for the exte'nsion-pivotsm on guides and providing them with adjusting-screws, as in the case of the block a, Fig. 4:.
I claim as my invention- 1. A relay or sounder in which a vibrating armature, elongated in respect to the poles of the electro-magnet, is combined with an electro-magnet having its poles adjustable from and toward the fulcrum of the armature-lever without breaking the circuit, all substantially as described.
2. A relay or sounder in which a vibrating armature is combined with an electro-magnet adjustable from and toward the fulcrum of the armature-lever, and from and toward the face of the armature, whereby, when the magnetis adjusted to increase the distance between the poles and the armature, the same movement will increase the distance between the point of attraction and the fulcrum of the lever.
3. In a relay or sounder, the combination of a vibrating armature having a widened curved face with an electro magnet adjustable on a pivot, and devices, substantially as described, for retaining the magnet in any position to which it may be adj ustedin relation to the fulcrum of the armature.
' 4. In a relay or sounder, the combination of an electro-magnet adjustable on a pivot with an armature having a curved face eccentric to the are described by the poles of the electromagnet when the latterisadjusted on its pivot, all substantially as and for thepnrpose setforth.
In testimony whereof I have signed my name to this specification in the presence ot'two subscribing witnesses.
