COMBINED TELEGRAPH KEY AND SOUNDER.
SPECIFICATION forming part of Letters Patent No. 38%,350, dated June 12, 1888.
Serial No. 256.531. (No modeLl To all whom, it 77mg con-earn.-
Be it known that 1, JOHN DOGGETT, a citi- Zen of the United States, residing at Plain City, in the county of Madison and State of Ohio, have invented anew and useful Improvement in Combined Telegraph Keys and Sounders, of which the following is a specification.
My invention relates to an improvement in combined telegraph keys and son nders; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is a side View of a combined key and sounder cmbodying my improvements. Fig. 2 is a similar View of the same, showing a different; arrangement of the instrument. 3 is a de tail View showing the manner of securing the detachable standard to the frame.
A represents the base or platfornnon which is supported a frame, I3. The said frame coniprises a vertical standard,(l, that has itslower end secured to the center of the base, and an arm, D, that extends horizontally from the upper end of the standard; also,formed integrally with the frame is a resonant tongue or arm, E, which is arranged over the standard and tends for a suitable distance over the arm I). The said arm D has near its outer end, on opposite sides, vertical ears F, and near the lower end of the standard is a vertical opening, G,whieh extends through the standard in a direction parallel with the axis of the frame.
I-Ircpresents thesoundiug arm,which has its trunnions pointed in the usual manner and en gaging recesses in the opposing ends of setscrews 1', thatare secured in the ears F. This sounding-arm is provided near one end with a percussion-screw, K, that is adapted to strike the resonant tongue orarm E and throw itinto .ibration, and at the outer end of arm D is an upwardlyextending percussion-screw, L, which is adapted to strike the under side of the short outer end of the soundingarm.
M represents a pair of cars or standards, which may be either formed integrally with the base of the standard O or separately there from. The said cars or standards are arranged on the base or platform immediately on one side of the standard 0.
N represents a key-lever having along'arm,
O, and a shorter arm, P,whieh arms extend in opposite directions. The trunnions of this key-lever are pointed and have their hearings in the opposing ends of set screw R, that are socured in the ears of standards M. The long arm of thekey-lcverextcndsthrough the opening in the standard C, as shown. To the outer end of the long arm 0 is secured a press-button, U. The said arm P is provided near its outer end,'on its lower side, with a contact point, V, adapted to make and break connection with the usual contact poi n t, XV, on the base or platform. X represents the usual switchlever to open the circuit when using the instrument for sending messages and to close the circuit when using the instrument for receiving messages.
Y and Z reprcsenta pair of rods which have their upper ends pivotally connected to the sounding-arm 011 opposite sides of the pivot thereof. These rods ex tend downward through suitable points in the long arm of the key-1e ver. Transverse openings A and B are made in the long arm of the key-lever and intersect the vertical openings therein, and are adapted to register with openings which are made through the rods Y and Z, respectively. On the rod Yis a coiled cxtensile sprin E,which has its lowerend secured firmly to the said rod and its upper end bearing under the arm D.
D represents a pin which is adapted to be passed through either of the transverse openings in the long arm of the key-lever and through the opening of either of the rods Y and Z, so as to secure the lower end of one of the said rods to the key-lever.
When the instrument is provided with helices (t and an arinaturej), secured to the sound ing arm, and is adapted to be operated by electricity, as shown in Fig. 1, both of the rods Y and Z are disconnected from Hickey-lever; but; when the said helices and armature are discarded and the instrument designed tobe used mechauicallyas for the use of learners-one of the rods will be connected to thekey'lever, as before described, and as shown in Fig. 2. \Vhen the key-lever is operated by the long arm, the rod Z is connected thereto; but when the key-lever is operated by its short arm the the instrument to give forth sounds varying inpitch.
It will be understood that when either of the screws H and I are used the screw L is adjusted so as not to strike the outer end of the sounding-arm.
A combined key and sounder thus constructed is adapted to be secured on a table between two persons and operated from either side, may be operated either mechanically or by means of electricity, and is adapted to give forth sounds of great volume.
Having thus described my invention, I claim- 1. The combination, in a telegraph-instrir ment, of the sounding-arm, the key-lever having a long arm and a short arm, extending in opposite directions and each provided at its outer end with a press-button, and the rod connecting the sounding-arm and the'key-lever, substantially as described.
2. The combination, in a telegraph-instrument, of the soundingarm, the key-lever adapted to be operated from either end, the
rods Y and Z, attached at their upper ends to the sounding-arm on opposite sides ofits pivot, and the device to attach thelower end of either of the said rods to the key-lever, substantially as described.
3. The combination, in a telegraph-instrument, of the sounding arm, the key lever adapted to be operated from either end, the rods Y and Z, attached at their upper e'ndsto the sounding-arm on oppositesides of the pivot, the device to attach the lower end of either of the said rods to the key-lever, and the spring bearing downward on the rod Y, substantially as described.
4. In a telegraph-sounder, the frame having the arm D and the resonant tongue or arm, the percussion screw Lat the outer end of arm D, the sounding-arm pivoted above arm D and having the percussion -screw K, adapted to strike the resonant arm, and the standard F, detachably secured to the frame and having the arm G, provided with the percussionscrews H and I, to engage the sounding'arm on its upstroke, all in combination, substantially as described.
In testimony thatI claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
JOHN DOGGETT.
