To all whom it may concern.-
Be it known that 1, DAVID H. (JOKER, a citizen of the United States, residing at Piedmont, in the county of Calhoun and State of Alabama, have invented new and useful Improvements in Electrical Signaling Mechanism, of which the following is a specification.
This invention relates to an electrical signaling mechanismwhe'reby a signal may be transmitted from an ofiice or other portion of a shop or establishment to notify an ofiicial or employee that his attendance at some certain point in a business or other establishment is Wanted.
The object of the invention is to provide a signaling system of this character which is simple, reliable, and efficient and by which that the calling-signal has been seen or heard.
With this and other objects in view the invention consists of the novel construction,
combination, and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in
which- Figure 1 is a perspective view of the box or casing containing the signaling devices at the receiving-station at or near the point of duty of the person to be called. Fig. 2 is a top plan View thereof, the top of the box or casing being removed to show the signal mechanism on the interior thereof. Fig. 3 isa vertical longitudinal section through the box or casing, and Fig. 4: isa diagrammatic view showing the signaling devices at the calling and receiving stations and the circuit connections.
Referring to Figs. 1, 2, and 3 of the drawings, the numeral 1 represents the main portion of a box or casing designed to contain the signaling mechanism at the receiving or called station, which box or casing is shown in the present instance as of rectangular form and having an extension 2 from one side thereof terminating in a depending portion 3, forming a chamber for the reception and operation of the signaling device, the said portion 3 be- 1 ing provided in its front side with a transparout pane or panel 4, through which the said The box or casing as a' whole is closed at the top by a cover 5,
Patented Nov. 28, 1905.
having a rectangular main portion 6 to close I the portion 1 and an elongated portion 7 to close the portions 2 and 3. This cover may be secured in any preferred way to render it readily removable for the purpose of applying, remov mounted to turn in adjustable bearings 12,
carried by a bracket 13, suitably secured to the casing adjacent the magnet 8. This disposition of the trunnions 11 provides lever 10 with long and short arms 14 and 15, the armature 9 being secured tothe inner end of thelong arm 14:, adjacent to the bracket 13, while the short arm 15 of said lever carries a weight 16 or analogous means for normally holding the armature out of contact with the cores of the magnet and projecting the arm 14 upward, as clearly shown in Fig. 3. To the outer end of the long arm-1 L is attached a link 17 from which issuspended a strip or bar 18, carrying a signaling device 19, (here shown in the form of a flag,) adapted to be raised and lowered by the movement of the lever to move it intoand out of register with the panel 4:, but which may be of any other form and construction to give the intended signal at the called or receiving station. It will be understood that when the magnet 8 is energized the arm 9 will be drawn down,
thereby pulling the arm 14 of the lever downward against the resistance of the weight 16, whereby the signal 19 will be forced downward or depressed in the portion 3 of the casing and brought into view through the panel 4. When the magnet 8 is deenergized, the
which binding-posts are respectively in connection with the two sides or positive and current to flow from the battery 26 to theelectromagnets 8 and energize said magnets to set the signal 19 at the station E and to break said circuit to elfe'ct the restoration of said signal to its normal position. In the conductor 24 at the receiving-station B is a bell 30 or other like signal, which is sounded when the signal 19 is. projected to call the attention of the employee or party signaled to the fact that said signal has been projected.
In the operation of the device it will be seen that a'person or official at the calling or signaling station B may transmit a signal to the receiving-station B to notify a' person at the latter station that he is wanted by simply closing the switch 27, which will project the signal 19 in the manner previously described. It is desirable to provide means whereby the person called may transmit a return-signal back to the calling-station to indicate that he has perceived the projected signal 19, and to this end a return-conductor 31 is provided, which is connected at one end, as indicated at 32, to the side 24 of the circuit A at the station B and is connected at its opposite endto a push-button or switch device 33, adapted to engage a contact 34:, connected at the station B to the other side 25 of the circuit A, so that when the said push-button 33 is engaged with the contact 34 the outside conductor 31 will be connected with the circuit A, and a current will pass through the said conductor. In the conductor 31 is a bell or other suitable signal 35, located at the station B, and which will be sounded or operated by the passage of an electric current through its actuating-magnet when the push-button 33 is engaged with the contact 3 1. By this means the called party at the receiving-station B may transmit a signal back to the signaling-station B, indicating that the signal previously transmitted from station B to station B has been seen or heard, after which the operator at the signaling-station B may restore normal condi tion by simply opening switch 27, as will-be readily understood.
It will of course be understood that in place of the flag-signal 19 an annunciator or other similar signaling device may be employed at the receivingstation B and a switchboard containing a series of push-buttons or switch devices used at the signalingstation B- in place of the signal hand-switch 27 whereby the operator at the signaling-station may call up any one of a number of employees or persons at or near the receiving-station. In this case of course each employee or person to be called will be distinguished by a number or other arbitrary signal exposed by the actuation of one of the drops of the annunciator. This arrangement, however, will require no change in the return-signaling means, as the one push-button may be used for transmitting the return-circuit to the signaling-station.
From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be understood without a further extended description.
Changes in the form, proportions,and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.
Having thus described the invention, what is claimed as new is 1. A signaling system of the character described embodying signaling and receiving stations, a circuit-controller at the signalingstation, acircuit governed by said controller, a casing at the receiving-station provided with end compartments arranged at different elevations, and a connecting portion joining said compartments, an electromagnet arranged within the upper compartment of said casing and connected with said circuit, an armature therefor, an eccentrically-pivoted signal-lever having its long arm connected with the armature and projecting through said connecting portion of the casing into the lower compartment thereof, and having its short arm disposed within the upper compartment, a signal connected to the long arm of the lever in the lower compartment, the latter having an observation-panel to expose said signal when the long signal-arm is lowered, means connected with the short arm of the lever within the upper compartment for normally holding the long arm thereof elevated, a return-conductor connected to the circuit at one side of the battery at the signal-station, and a switch device for connecting said conductor to the circuit on the opposite side of the battery at the receiving-station.
2. In a signaling mechanism of the character described, a casing provided with a main compartment, a signaling compartment extending below the plane thereof and provided in its lower portion with an observation-panel, and an elongated extension connecting said compartments, an electromagnet arranged within the main compartment, an operatinglever eccentrically pivoted within the main compartment and carrying upon the-long arm thereof adjacent to the pivotal connection an armature, the long arm of the lever extending through the connecting portion of the casing into the upper portion of the signalingcompartment,aretracting-weightconnect- In'testimony whereof I aflix my signature in I presence of two witnesses.
