SPECIFICATION forming part of Letters Patent No. 452,026, dated May 12, 1891.
Application filed July 15, 1890. Serial No. 358,860. (No model.)
To all whom it may concern:
Be it known that I, CHARLES J. KINTNER, a citizen of the United States, residing at New York, in the county and State of New York, have made a new and useful Invention in Electrical Signaling Devices, of which the following specification, taken in connection with the drawings, is a full, complete, and exact description.
My invention relates particularly to electrical signal-transmitters; and its objects are, first, to devise a transmitter adapted for central-station use and to automatically transmit any one of a series of prearranged signals;
second, to prevent the interruption of a signal during the time it is being transmitted; third, to allow one signal, and one signal only, to be transmitted at a time and to restore the signal mechanism to its normal condition after this transmission has been completed; fourth, to accomplish the several features hereinafter indicated. I accomplish these several objects by the use of the mechanism hereinafter described, but particularly pointed out in the claims which follow this'specification.
My invention is especially. designed and adapted for use in connection with the automatic individual signaling apparatus invented by Adin A. Hatch and disclosed in his patent, No. $5,983, granted by the United States Patent Office on the 2d day of September, 1890, and with analogous signal-receiving apparatus. In the invention disclosed in said patent to Adin A. Hatch individual signal-receiving apparatus is. actuated at outlying stations and caused each to respond to its own particular transmitter, in which characters of the Morse codeare utilized and combinations of varying orders of intermittent current impulses are transmitted for the purpose of operating such individual re-' ceivers to the exclusion of those not wanted.
My invention is particularly designed for use on a main-line circuit wherein there is located a signaling-battery and a series of such individual automatic receivers, and it will be clearly understood by referring to the acco1n panying drawings, in which- I Figure 1 is a plan view showing the circuitnaling apparatus indicated connections in diagram. Fig. 2 is a sectional view of Fig. 1, taken on line 2 2, as seen looking from left to right in the direction of the arrows. Fig. 3 is a detail sectional view of one of the signal-disks.
Referring now to the drawingsin detail, to is the main line running from the earth E through a series of outlying individual sigby signal-boxes 1, 2, 3, 4, and 5.
'B A is the signaling-battery located at a central or signaling station from which it is desired to call any of the outlying operators through the agency of my improved apparatus, which I will now describe in detail.
0 is a clock mechanism impelled by spring or weight power, or any preferred type of energy, the last gear-wheel thereof meshing with a pinion P on a shaft B, journaled at J J.
S S S S S are signal-transmitting disks, each of which has upon its surface a prearranged signal in the nature of conductingteeth adapted to contact, respectively, with theconductingsignaling-armsEtoE These signaling-disks are arranged, as shown, at the desired distances apart on the axles B B, and
are electrically in contact therewith. On the right-hand end of the shaft B is a cam-wheel B having an irregular cam on its surface, which is adapted to give lateral motion to a bar or connecting-link K, having sliding bearings in the frame of the apparatus, this motion being imparted by a lever L pivoted at d, and having a pin which plays in the camgroove at one end and a corresponding pin P on the bar or connecting-link K, as clearly shown.
P P are pins arranged on the upper and lower sides of the sliding bar or connectinglink K, said pins lyingin the paths of the signal-arms E to E and E", &c. These signal-arms are connected at their pivot-points with the main-line 10 by wires to 112 10 to w &c., respectively, and the contacting ends of said armsrest normally on or near the exterior ends of beveled contacting segments N, the interior or horizontal portions of which constitute part of the signal-disks proper.
F F F, &c., are non-conducting disks or guards, each having a notch in that portion of its periphery which rests normally near the free ends of the arms E to s is a conducting-spring which bears on the shaft B, and connects the battery B A electrically with said shaft, and s is a similar conducting-spring connected at one end to the main line to, with its other end resting normally on a conducting-lug L, so that the current from the battery B A passes directly to line by wire 20, spring 5, shaft B, lug L, spring 5, and through the signal-boxes 1, 2, 3, 4, and 5. In Fig. 2 I have shown two sets of these transmitters arranged upon parallel shafts B B, the shafts being geared together through the agency of a common driving- Wheel and pinions P, and adapted, therefore, to rotate both in the same direction and at the same speed. Of course any number of such shafts may be geared to the mechanism 0. The axles B B are both in metallic contact with the frame of the machine, While the signaling-arms E to E are insulated therefrom. The lower arms E are journaled around the bearings of the upper set of signalingarms by long journal-bearings R, and are adapted to bear against pins on the lower side of the bar or connecting-link K. (See Fig. 2.)
The operation of the apparatus is as follows: Under normal conditions the battery-current from B A passes directly to line through the wire to, as already indicated, or if the ends of the arms E to E rest normally against the beveled bearings N it will pass to line to through the branch wires to w to 1.0 Suppose now it is desired to transmit a signal from some one of these transmitting-disks, as S The signal-arm E is pushed to the left through the agency of its handle, and the free end thereof is brought into alignment with the signal-teeth on the disk S while the other end of the arm E is forced against one of the pins P, thereby causing the bar or connecting-link K to be thrust to the left, and with it the lever L so hat the pin on the free end of said lever is released from its bearingn on the shoulder in the cam of the wheel B and the clock mechanism is allowed to impart an advance motion to the shaft B. As this shaft rotates, therefore, the circuit is broken, first through the branch 20, its spring 3, and lug L, and the current is transmitted from the battery through the shaft to the disk S and through the teeth thereof in succession as it revolves to the arm E branch wire 20 linewire to, through the several outlying signalboxes 1, 2, 3, at, and 5, actuating the apparatus in box 2 to the completion of its phase and warning the operator at that station that he has been called. Then the shaft B has made one comple e revolution, the cam-wheel B causes the pin in the end of the lever L to be forced to the left, and hence imparts to the bar or connecting-link K a motion to the right, thereby causing the pin P on the left-hand side of the lever L to restore said lever to its original position parallel with levers L, L L or L At the same time the shaft is again checked in its rotation, and the apparatus is ready for the transmission of the same or any one of the signals, as before. It will be seen that after the apparatushas once been started the signal-lever cannot be removed from the signal-disk, nor can any other signal-lever be placed in operative relation with its signaldisk until the shaft B has made a complete revolution and is restored to its normal condition, so that the contacting ends of all the levers are in the paths of the notches of the disks F. WVhen it isdesired to transmit any signal from one Of the signal-disks on the shaft B, the operator actuates one of the lower set of signal-levers E", as seen in Fig. 2, said signal-levers being the duplicates of those shown in Fig. 1 and being operatively connected with the bar or connecting-link K by pins on the lower side of said bar, in the same manner as the arms E, &c., were connected to that bar by pins P.
It is of course obvious that when the free ends of the signal-arms E to E restnormally on the shoulders N, when said shoulders are of conducting material and connected with the signal-disks, the spring 5, shunt-wire w, and lug L may be done away with. I prefer, however, the arrangement shown, and that the free ends of the arms E to E be absolutely out of contact with the shoulders N, 7
thereby diminishing the friction as much as possible at starting.
I do not limit myself to the use of this apparatus with the special form of signalingreceiver above referred to, as it is obvious it may be utilized in any place where any one of a series of signals is to be sent to one or more outlying stations, as in telephonic, telegraphic, fire-signaling and analogous apparatus. Nor do I limit myself tov the specific mechanism herein shown and described for causing any one of a series of signals to be transmitted from a single multiplex'signaltransmitter to the exclusion of any other in dividual signal from the same transmitter during the time that the first signal is being turned in, as I believe it is broadly new with me to so devise a multiple signal-transmitter that during the time any one signal is being transmitted no other signal can be turned in from the same transmitter.
I am aware that it is old in the art of firetelegraphy to cause a given signal-transmitter to so act upon the other transmitters located at outlying signal-boxes as to lock them out during the time that a signal is being sent in from the first-named box, and my claims hereinafter made are limited to a multiplex transmitter, in which all of the signals are sent from a common instrument located at a single signaling-station.
