OHIO, ASSIGNOR OF ONE-HALF TO EDIVIN GOODER, OF SAME PLACE.
TELEGRAPH INSTRUMENT.
SPECIFICATION forming part of Letters Patent No. 606,449, dated June 28, 1898.
Application filed October 18, 1897.
T0 at whom it may concern.-
Be it known that I, JAMES L. CUTLER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and usef ul Improvements in Telegraph Instruments; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to certain improvements in magnetic telegraph instruments and the like, and has for its object to provide an instrument of a simpleand inexpensive character which shall be strong and durable and wherein the electromagnetic devices are so constructed and arranged as to permit of operating the instrument with a minimum expenditure of electromotive force, so that an economy in the employment of batteriesis permitted.
The invention consists in certain novel fea-' tures of the construction, combination, and arrangement of the various parts of the im proved instrument whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted for use, all as will be hereinafter fully set forth.
The novel features of the invention will be carefully defined in the claims.
In order that my invention may be the better understood, I have shown in the accompanying drawings a telegraph sounder or receiver embodying my improvements, in which drawingsc Figure 1 is a side view showing the improved instrument. Fig. 2 is a plan View of the same, and Fig. 3 is a fragmentary sectional view taken. in the plane indicated by the line a a in Fig. 1 and showing the arrangement of the trunnion-screws whereon the armature-lever is pivotally mounted.
In the drawings, 1 indicates a base, usually made of wood and serving to intensify the sound of the instrument mounted thereon, said base carrying binding-screws 2 2, from which lead wires (not shown) to the ends of Serial No. 655,538. (No model.)
the magnet-coil, so that the instrument may be connected in the telegraph or other circuit in the ordinary manner.
3 indicates a metal bed-plate or bridge secured to the upper face of the base 1 by means of screws or the like and carrying the electro* magnet, which comprises a magnetcoil 4, wound on a core 5, to the lower end of which is secured a transverse bar or yoke 6, of soft iron, held by screws or otherwise to the flat top surface of the bridge 3 and having its extremities 7 and '8 bent up at right angles and 011 opposite sides of the magnet-coil, with their upper ends substantially in line with the upper end of the core 5.
' To the upper end of the arm or standard 7 of the bar or yoke 6 is secured, by means of screws or the like, a plate 9, the opposite side portions 10 of which are bent at right angles, as shown in Fig. 2, so as to extend over the side surfaces of the said arm 7, and the up per ends of said side portions 10 are bent in opposite directions and extended above the upper end of said arm 7, so as to permit the armature-lever 11 to be pivoted between them in position directly over and in line with the upper ends of arms 7 and 8 and of the core 5 of the electromagnet. As shown in the drawings, the armature-lever 11 is pivotally mounted between trunnion-screws 12, having jam-nuts, in the usual way.
j Upon the upper end of the arm 8 of the bar or yoke 6 is also held, by means of screws or the like, a plate 13, having its upper end bent, as shown at 14, to form a stop to limit the movement of the armature-lever 11, the free end of which vibrates'between the upper ex 'tremity of said arm 8 and the said stop. The said bent end 14 of plate 13 carries an adjusting-screw 15, having a jam-nut, and the free end of armature-lever 11 is also provided with an adj usting-screw 16, having a jam-nut and adapted for engagement with the upper extremity of the arm 8. By this arrangement it will be seen that the vibratory movement of the armature-lever may be conveniently and nicely adjusted.
The opposite end of the armature-lever 11 is made to project beyond the arm 7, at which it is pivoted, and is provided with an adjusting-screw 18, having jam-nuts and connected at its lower end with a spiral spring 17, the
too I lower end of which is connected to an arm 10, projecting from one side of the bridge ii. The spring 17 serves to hold the armature-lever 11. with its free end in raised position, as shown in Fig. 1, but permits it to be moved toward the magnet when the same is energized, the extent of movement being regulated, as will be readily understood, by means of the screws 15 and 16, while the adjusting-screw 18 permits of adjusting the tension of the spring to the required degree.
In operation, when the instrument is connected in the telegraph or other circuit and said circuit is closed, the [low of the current through the magnet-coil at will serve to energize the magnet and cause the core 5 of the same to attract the armature-lever 11 and move the same in the ordinary way. At the same time the bar 6, which, together with said core 5, is made of soft iron and is connected with the lower end of said core, will act as the opposite pole of the magnet, and the arms or standards 7 and S of said bar, being arranged on opposite sides of the core 5 and in proximity to the armature-lever 11, will also attract the said lever, so as to move the same downward. \Vhen the circuit is opened or broken, the spring 17 will serve to raise the armature-lever, as will be readily understood, the sounds produced by the movement of the lever correspon ding with the dots and dashes of the telegraphic code and being intensified by the metal bridge 3 in a well-known way. By this arrangement it will be seen that the upper end of the core 5 will assume an oppo' site polarity to that of the upper ends of the arms 7 and 8 of the bar 0, and said arms and core, being arranged in line with each other and with the pivotal point of the armature lever 11, will serve to attract said lever much more strongly than is the case where the armature is arranged in the ordinary manner, so that a considerable economy in battery power is permitted, it being possible to cmploy a weaker current in the local circuit.
From the above description it will be seen that the instrument constructed aceordin g to my invention is of an extremely simple and inexpensive nature and is especially well adapted for the purposes for which it is designed, and it will also be obvious that the device is capable of considerable change without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts herein set forth.
Having thus described my invention, I elaim- 1. In a telegraph instrument or the like, a
magnet comprisin a core, a coil wonn d thereon and a soft-iron bar connected at its central part to one end of the core and having its ends bent to form arms extending along opposite sides of the coil with their extremities adjacent to the free end of the core, in con1- bination with an armaturedevcr located in the field of the magnet pivoted on one of the arms and extending in line with the tree ends of the arms and core, substantially as set forth.
2. In a telegraph instrun'leut or the like, the combination of a core, a coil wound there on and a soft-iron bar connected at its central part to one end of the core and having its ends bent to form arms extending along opposite sides of the coil and having their extremities adjacent to the free end of the core, in combination with an armature-lever located in the field of the magnet and pivotally connected with one of said arms in position to move in line with the other arm and the core, and stops on the last-mentioned arm to limit the movement of the arm atnrc-lerer sn 1 stantially as set forth.
3. In a telegraph instrument or the like, the combination of a magnet comprising a core, a coil thereon and a bar connected at its central part to one end of the core and having its ends bent to form arms extending along opposite sides of the coil with theirextrcmities adjacent to the free end of the core, a plate carried by one arm, an armature-lever pivotally connected to said plate, a plate carried by the other arm and forming a stop to limit the movement of the armattire-lever, and a spring to hold said lever in its normal position, substantially as set forth.
4-. In a telegraph-sounder, the combination of a magnet comprising a core, a coil wound thereon and a soi'tdron bar connected at its central part to one end of the core and having its ends bent to form arms extending along opposite sides of the coil with their extremities adjacent to the free end of the core, a plate secured to one side of one arm and having upwardly-proj ectin g side portions, an armature-lever pivoted between said side portions and arranged to move in line with the upper ends of the arms and core, stops carried by the other arm to limit the movement of tho armature-lever, and a retracting-spring [or the armature-lever, substantially as set forth.
In testimony whereof I ailix my signature in presence of two witnesses.
