ELECTRO-MAGNETIC TRANSMITTING AND DISTRIBUTING THERMOSCOPE- SPECIFICATION forming part of Letters Patent No. 359,210, dated March 8, 1887.

Application filed J ulv 22, 1886.

the general form and construction the same as that for which an application for Letters Patent No. 200,458 has been filed by me, April 18, 1886, someof the features of construction and organization which I have set forth in my application N0.'206,154, Med J uue 24, 1886, for anelectromagneticreceiving,transmitting, and distributing thermoscope. Such applied features in their new relation to atransmitting thermoscope and other devices added thereto I now describe in this specification.

Serial No. 20am. N0 model).

Like letters designate corresponding parts in ail of the figures.

In the drawings, A represents the lower vertical cylindrical part, and B the upper horizontal cylindrical part of the case; 0, the thermostatic coil in the lower cylindrical part; D, the index in the upper cylindrical part; E, the vertical thermostatic shaft or spindle, and F the horizontal index-shaft, as in my said application for a transmitting-thermoscope.

In the present organization I do not have a divided index-shaft, as in the said application, but connect the two shafts by a suitable positive gearing, by which the desired relative speed of the two shafts may be obtained.

In Figs. 3 and 4 I Show a worm-gear, a, on the thermostatic-coil shaft E, gearingdirectly into a worm-wheel, I), on the index-shaft.

In the modified construction shown in Figs. 5 and 6 I show the worm-gear a, gearing into an intermediate worm-wheel, b, which in turn gears into a pinion, c, on tlieindex-shaft. One or more thermostatic coils and worm-screws may be used.

In combining the organizations of the two inventions set forth in the two applications above referred to, I employ two electro-magnets, G H,Figs. 1 and 2, located in the upper cylindrical part of the instrument and mounted on the plate 01 back of the dial of the index D, the former magnet, G, being in the increasing-temperature circuit and the latter magnet, II, being in the decreasing-tempera ture circuit in the main line reaching to an observatory or station. These electro-magnets, through their armatures e f and their armature-levers I J, actuate, respectively, pawls g h and detents M, which take into ratchet-wheels K L on shafts Z, all precisely in the same way and by similar adjustments as set forth in my aforesaid application No. 206,154. From this point of action the or-- ganization is different from that of the said application. Thus, the pinions m a on the shafts k l in the present invention gear into an interior set of gear-teeth, 0, of an annular or ring circuit-closer, M, which is held in position by the said pinions, being at opposite sides thereof, and by two grooved frictionbearing against the outer edges of the ring in positions a quarter of a circle distant from the said pinion, or thereabout. The organization of this annular circuit-closer and its operation in connection with associated parts are as follows: The ring is made with two metallic parts, r s, separated by an insulating-strip, t, inserted between them, as shown. The outer .part, 7*, of the ring has metallic connection with one or both of the fixed pivots q g by one or both of the friction-pulleys p p and by one or two elastic metallic strips, u, attached to the said pivots and bearing against the periphery of the ring, and one or both of the said pivots are put in .circuit by the wire 2 of the increasing-temperature electro-magnet G. The inner part, 8, of the ring M has also metallic connection with the wire 3 of the decreasingtemperature electro-magnet H. through one or both of the pinions m n, shafts kl, and a metallic supporting bridge or bracket, 12, which is mounted on but insulated from the back plate, d, of the instrument, and in which the said shafts have their bearings, one end of the magnet-wire 3 being attached to the said bridge. j

The arrangement of the parts thus far described is such that at each breaking and 010s ing of the increasing-temperature circuit the annular circuit-closer M will be moved the distance of one degree of the \temperature' scale in the proper direction by the action of the electro-magnet G inthat circuit,'and at each breaking and closing of the decreasingtemperature circuit the said annular circuitcloser will similarly be moved one degree of the temperature-scale in the opposite direction.

Thus far, however, no provision for closing and breaking the circuits has been described. Here a construction partly belonging to my electro magnetic transmitting thermoscope described in my application No. 200,458, above referred to, is employed. Thus the thermostatic coil 0, its shaft E, and the indexshaft F, geared to the said shaft E, are used, whereby each change of one degree of temperature of the air in which the instrument is situated turns the said index-shaft F one degree of the temperature-scale in one or the other direction, according to whether the temperature is increasing or decreasing, these movements of the shaft corresponding and harmonizing with those of the annular circuitcloser M, above specified. Then upon the rear end of the index-shaft F is secured an arm, N, having an elastic tip or extension, w, which is arranged to touch either one of two pins or projections, y, one projecting from the outer part, 1*, of the ring circuit-closer and the other projecting from the inner part, 8, of the said ring, as shown in Figs. 1 and 2. The tip of the arm, as shown, extends between the said pins, and it is so arranged between them that it can have one degree of movement and a slight additional movement, as little as practicable, in moving from one to the other. The

BEST AVAILABLE co index-shaft F, on which this arm is mounted, is in metallic connection with the battery-wire or return-wire of both circuits, so that when the tip of the arm touches the pin at it closes the increasingteniperature circuit and when the tip touches the pin 3 it closes the decreasing-temperature circuit.

The movement resulting from the combined mechanisms above described is as follows: Sup pose the temperature of the atmosphere where the instrument is located is increasing and that the pin 1- on the circuit-closer is one degree in advance of or away from the circuitclosing arm N, as soon as another degree of increasing temperature is reached, and consequently the arm has moved forward one degree, it touches the pin 1' and closes the increasing-temperature circuit. The armaturelever of the magnet G is thereby moved and the annular circuit-closer M is moved onedegree, thus moving its pin 9" one degree away from the arm N again, and consequently again breaking the circuit. The next increasing degree of temperature again'brings the arm into contact with the said pin 1' and again closes the circuit, with a repetition of the resultant action. Thus the movements are repeated as 'long as the temperature increases.

The movement is precisely the same in the opposite direction when thetemperature is decreasing, the arm N then coming successively into contact with the pin 3 on the annular circuit-closer and being separated therefrom by the retreating movement of the said circuit-closer.

In Figs. 2, 3, 4, and 7 I show an additional device whereby a local battery is used for actuating the electro-magnets G H and by them the circuit-closer M, so that the main line battery-wire may be relieved of this work, and thus be better adapted to transmit thermometric indications to long distances.

All the parts above described are here retained, and in addition the following device is employed: Two vibratory, generally obtuseangled, levers, O P, are mounted, as shown, upon a tubular pivot, a, Fig. 3, around the index-shaft F, and they are connected to the armature-levers I J of the electro-magnets in precisely the same way as the ring or circular multiple circuit-closers set forth in my aforesaid application No. 206,154, namely, by means of arms I) c, projecting laterally from respective levers near their upper ends, and wires orrods d 6, connecting the said arms respectively with the armature-levers, as represented in Fig. 2. Here the

wires

2 and 3 of the respective electro-magnets and returnwire 4 for the two are connected with thelocal battery Q, so that when the circuits are closed by the circuit-closing arm N this battery operates the annular circuit-eloser M and also said arms 0 P, which are circuit closers and breakers for themain-line circuits in the following manner: The increasing-temperature wire 5 of the main line is parted at the instrument, and its two ends at the parting are respectively IKO ITO

connected with two post or stud plates, f 9, attached to but insulated from the plate (1 of the instrument, and therefore from each other. Similar post or stud plates, h i, for parting the decreasing-temperature line-wire 6 are attached in a similar way to the plate (I, the two sets of post or stud plates being suitably placed in different positions, as shown, to suit the positions of the lower ends of the levers O P. On the respective plates f h are secured projecting posts BB, upon the outer end of which, respectively, are pivoted at j bell-crank levers S S, as shown in Fig. 7, and on the other plates, i, respectively, are secured studs T T. The relative positions of the post R and the stud T of each set are shown in the said Fig. 7, and the associated lever S is arranged to have one arm, I, bearupon the outer end of the stud, as shown, being pressed thereon by a light spring, or its equivalent. Thus the circuit through the wire is completed and held closed 'by this device. Platinum or silver contact-points m m areplaced on thestud and lever, as shown in the same figure. Now the lower arms of the respective levers O P have their lower ends, a n, (insulated so as not to interfere with the main circtiits,) brought into such relation to the bell-crank levers S S as to bear against .the other arm, 0, of each, and that when the levers are moved by the respective magnet-levers I J they will lift the respective arms Z Z" of the bell-crank levers from the stud T T and break the main-line circuits, .one or the other, as the case may be. The breaking of the local circuit, which immediate] ydollows this action of either lever O or I, causes the lever to be retracted, and thus the main circuit is immediately closed, again producing the requisite transmission of the temperatureindications to the distant observatory or station. The two circuit-wires 5 and (i are connected with the single return or battery wire 7 of the main circuits.

It is obvious that it makes no difference whether the levers O P are caused to lift the levers S S by the direct positive action of the armature-levers I J of the electro-magnets or by the counter-springs z z of the armaturelevers. In the arrangement shown in the drawings the latter way is shown, the springs z z moving the levers O P positively, and these springs are strong enough to overcome the lever-sp rings 7; 7.:'.

For local distribution this device may bein separate transmitting-circuits, the battery Q being a separate-line battery, and since these levers O I may be multiplied or have differentbran ches. as with the circuit-closing wheels set forth in the said application No. 206,154, the present instrument is assimilated to that instrument in this particular, and thus may fulfill, as a transmitting-instrument, the same additional functions as the receiving-instrument therein set forth.
