Beit known that'L'F-RANZ RITTMEYEIt, acitizen of the SWiss'Confederacy, ,and a'resident of Appenzell, Switzerland, have lnvented *certain new and useful Improvements in De.- vices for 'Indicating at a'Dist'ance the Height of a Water-Level, of which the following s ja specification. v
- This invention relates to a device. for indicating at-a. distance the height ofhalwatenlevel, and'especially to a devlce' intended for water-supply plants.
The device may also be used for indicating at a-distance' the variations of any other level, such as the levelof thermometer.
The device comprises at the water-resen voir a transmitting-station and a registering station, which maybe mounted at any place,
as well as the connecting-ducts.
the mercury in a Theannexed drawings, given by way of exam 1e, show a special form of the invention.
igure 1 shows a perspective of the trans- I mltting-station. Fig. 2 shows the registerv n -station'.
. 0th stations are connected-by a double e. When the'water-level a rises, the .fioat bis also raised, the chain-wheel c is rotated, and with it the axis (1. The rotation of the latter produces the shifting of the slide-piece e owin to the fact that'the rod (1 is sc'rew-threade as atd, and. works in a'threaded bracket (1, carried by the piece e.
. side the electrical-resistance g, com osed'of equal unities. Allthe unities of t e latter may come in contact with the slide e, according to the position of the latter. The slide a is always connected with the contact-bar f.
An electric current may becondu'cted by the slide e to any one of the unities ofithe resist position of the slide e, will ordinari ance g'. y e
en an electnc current ,1s conducted the weakercurrent.is'conducted to the line;
wire it; the stronger current to the wire '5. current thus split up by the transmlttlng-station, Fig. 1, arrives b the two wires't and-h to the indicating-station, Fig. 2. In the latter two resistances 7c and 1, corresponding exactlyto the resistance g, are arranged m such Specification of Letters Batent. i Application filed liarch 8,1905 Serial No. 249,072.
When i the slide The piece a touches on one side the contact-bar f and on the other scribed, the combination cated at a transmitting-station comprising a through the contact-bar f, it is split u by thei iPatentedJuiy 31, 190 6.
a mannerthat they are always connected by a slide m, carrying the two contacts 'n ando, which are not connected one to the other and through which the current is conducted from the wires h and 'i throughv the resistances]; andl to the bars 1) and Asshown by Fig. 2, rent in the resistance takes place in anopposite direction to that in the resistance Z. Owing to this arrangement Fig. 2, only a resistance is put into the circuit which is equal to the resistance is or lin Fig. 2 or also to-the resistance g in'Fig. 1
By moving the slide m. it will be eas to (1 out a position in which the sum 0 the resistances in the circuit f 9 ile is e ual to the sum of resistances in the circuit f 9 Z. This is the position in which the resistances'k and l .are divided -;by the contacts'n and 0 proportionally in such a ,manner as the resistance 9',
Fig. 1, is divided by the slide e into two parts.
.in' the station.
A measuring apgmratps 1', connected'to the I:
contact-bars 1) an two currentsflowin'g from the bars 11 and are of the same force. All that is then to do is to move the slidem bymeans of the drivin wheel 8 until an equal intensity of current is indicated. The position'of the slide m of the 1 station 2, Fig. 2, indicates av corresponding position of the slide e of thestation 1, so that m is provided with a needle and a, scale the'hei ht of the water-level is indicated at the stat1on'2. The above-described device may also be used for measuring at adistance anyother' oscillations of the level of a liquid.
Having now fully described my, said invention, what I "claim, and desireto secure by Letters Patent, is' T 1. In anapparatus of the character depredetermined series sistances located at-a each com rising a series of umties equal to those in t e resistance at the transmittingstation, an electrical connecting-linebetween of unities, similar restationand one end ofa resistance at the receiving-station, an electrical connecting-line betweenthe o posite end of the first-named resistance an receiving-station and- .g, Wlll permit to see if the of a resistance 10- 'onefend of theresistance at the transmittingone end of the other resistance at the receiving-station, means at the transmitting station adapted to ,intercalate a variable number of the .unities of'the resistance at that station into thetwo'connectv ing-lines leading to the receiving-station, indicating means at the receiving-station comprising a bar adapted to var the number of unities of the resistance at t e receiving-station included in the two connecting-lines, the various elements being so arranged that the sums of the resistances intercalated in both lines are always equal in all reading positions of the indicating means, means for supplying electrical current to the intercalatin means at the transmitting-station, and an e ectrical measuring device in electrical connection with the intercalating means at the receiving-station and adapted to indicate when the intensities of the currents flowing through the two connecting-lines are equal.
2. In an apparatus of the character described the combination with a rotatable shaft located at a transmitting-station, an indicating arm adjustably mounted on and movable by said shaft, a contact-bar with which said arm is in contact, an electrical retrical measuring device electrically connected with the contact-bars at the indicatingstation.
In testimony whereof I have hereunto set my hand in presence of two witnesses.
