LEONARD VALDO, OF NEW HAVEN, CONNECTICUT.
SYNCHRONIZING CLOCKS.
SPECIFICATION forming part of Letters Patent No. 268,322, dated November 28, 1882.
Application filed July 5, 1852. (Yo model.)
T 0 all whom it may concern:
Be it known that I, LEONARD WALDO, of New Haven, in the county of New Haven and State of Connecticut, have invented new lmprovements in Synchronizing Clocks; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference narked thereon, to be a full, clear, and eXact description of the same,and which said drawings constitute part of this specilication, and represent, in-
Figure 1, a plan view, illustrating the system; Figs. 2, 3, and 4, detached views, enlarged.
this invention relates to a means for regulating numerous clocks from a single clock or regulator. Communication between a regulating-clock and other clocks, or between some point of regulation and the clocks, has been made by means of wires and electric currents, the circuit being made and broken at certain predetermined times to bring the pointers of' the clock to the exact position at such predetermined time, and such communication has also been made through pneumatic tubes arranged between the point ot' regulation and the clocks to be regulated, by giving to the air in the tubes that impulse at said predetermined time or times. The irst is expensive and liable to derangement. The second is eX- pensive and inconvenient, because it requires the laying of pipes specially for the purpose.
The object of my invention is to make this communication at a tritling expense and without the possibility of derangement; and it consists in combining with the gas-holder and gas-mains of a common gas-lighting system a second gas-holder, which may be ot' small capacity,and in which common gas or its equivalentshall be held undera pressure greater than the natural or regular pressure in the gasmains, communication being made between the said high-pressure holder and the mains by mechanism to be operated at a predetermined time to open communication from said highpressure gas-holder to the mains, at the same time cutting .oi' the said mains from the principal gas-holder, whereby the high pressure which is let into the mains will communicate to the gas in the mains an impulse which will be felt throughout the entire extent of the system and communicated to the synchronizing` mechanism of clocks which may be put into connection with the gas in the mains, and, so soon as the impulse has been given, operates to cut off the high pressure and reopen communication with the principal holder, and as more fully hereinafter described.
A represents the principal gas holder, and in which the pressure is the regular working pressure of the system, and from whichI the main B receives its gas in the usual manner.
C is a small gas-holder, in which the pressure of gas is considerably greater than thatin the principal holder, but is in communication with the main by means of a threeway cockone, u, opening toward the principal holder,
the second, b, toward the high-pressure holder, the other, d, into the main. Through the plug of the cock is au opening, e, which in one direction, as in Fig. 2, makes communication between the principal holder and the main and cuts ofi" the high-pressure holder. In the Asecond position, as seen in Fig. 3, communication is opened between the' high-pressure holder and the main and cut ott from the principal holder. Now, it' at any time the plug of the cock be turned from the position seen in Fig. 2 to that in Fig. 3, pressure in the mains will be instantly increased `to the extent of the pressure of the high-pressure holder C. Then, it' returned to the position seen in Fig. 2, the high pressure is cut oft'. communication opened with the principal holder, and the pressure in the pipes reduced to the pressure oi' the principal holder. There istherefore by the turning of the plug ot' the cock animpulse given to the gas in the main which will be felt throughout the entire extent ot' the system. This impulse may be imparted to the regulating or synchronizing mechanism by various appliances.
The receiver E may be made in bellows-like form, as seen in Fig. 4, into which gas is led,
and which will expand according to the impulsegiven to the gas in the main. To one of' the'heads-otl the receiver one arm, a, of a lever bears, the other arm in connection with any'device for communicating the impulse. When the impulse is imparted to the gas, as before IOO described, it will cause an instant expansion ot' the bellows, which expansion will turn the lever, as seen in broken lines.
It is unnecessary in this specification to describe the various regulating mechanisms for clocks to which the impulse may be imparted. These are too well known to require description, the essential feature of my invention beingtheimparting to the regulating mechanism an impulse through the gas in the pipes of a gas system.
The cock D may be in connection, say, with an observatory or other point from which the predetermined impulseis to be given by means of wires or otherwise, so that the impulse may be instantly given and so quickly cut off that theincreased pressure will not materially ai'ect any burners which may be in operation at that instant. Thus l utilize the gas already in the mainsthercby avoiding all expense of communication between different points. No gas is consumed by the operation, that which is ein ployed to give the impulse being returned to `the principal holder,which avoids the expense of the necessary plant for pneumatic or electrical connection and without the same liability of derangement of communication.
What I claim is- 1. The combination of the principal gasholder, its mains and branches, an auxiliary holder charged with a higher pressure than that of the principal holder, mechanism, substantially such as described, to open communication between said hi gh-pressure holder and the gas-mains and to cut oft' the same, with mechanism, substantially such as described, in communication with the gas from the mains, whereby the impulse imparted to the gas in the mains from said high-pressure holder will be imparted through the gas in the mains to the said receiving mechanism, substantially as described. v
2. Ihe combination ot' the principal gasl1older,its mains and branches, a second holder, the pressure of' which is greater than that of the principal holder, and in connection. with the mains, and mechanism, substantially such as described, for applying` the pressure ot' the said second holder to the mains, at the same time cutting off the principal holder from the mains, and then to cut ot't' the said second holder and restore the connection between the principal holder and the mains, whereby an impulse will be imparted to the gas in the mains and then the normal pressure restored, substantiallyyas described.
