APPARATUS FOR WEATHER-SIGNAL STATI ONS.

SPECIFICATION forming part of Letters Patent No. 326,558, dated September 22, 1885.

Application filed March 21, 1885.

To all whom it may concern:

Be it known that I, RALPH HIRsH, of Syracuse, Onondaga county, State of New York, have invented a certain new and useful Oombination of Instruments OomposingaWeather- Signal Station for Forecasting the Weather, of which the following is a description.

My improvement consists in an anemometer and anemoscope combined, and located on or above the roof of the station, and communicating with dials placed in a case or cabinet below, where I also place a barometer and thermometer, which together comprise the instruments necessary for forecasting the weather, and so arranged as to be at once available for the purpose. The mechanism by which this is effected is shown in the accompanying drawings, in which Figure 1 is an elevation of a sectional portion of the station with all the instruments in place. Fig. 2 represents a vertical front and side elevation of the gearing connecting the anemometer with the dial on in the case; Fig. 3, a like view of the anemoscope.

The same or like parts are indicated by the same letters in all the figures.

The anemometer consists of four hollow half-spheres set at right angles on horizontal arms projecting from the upper end of a vertical shaft, so as to measure, by the following proportions, a half-mile on the dial by one revolution of the needle thereon: The arms a a hold the half-spheres at a distance of 11% inches at their periphery, being constructed on a basis of thirty-seven inches displacement in one revolution. The shaft 12, projected above the roof, extends down to an adjustable step in the supporting-frame below. On the lower end of this shaft there is a worm, c, gearing into a worm-wheel, d, of forty-four teeth on a horizontal shaft, 01, that carries a six-leaved pinion, e, which gears into a wheel, f, of sixty teeth on a parallel shaft, f, on the other end of which there is a pinion, g, of thirteen teeth outside the frame. This pinion 9 gears into a wheel, h, of twenty-six teeth, turning on a stud projecting from the frame. A ratchet-wheel, i, is affixed to and turns with wheel h on the same stud. This ratchet has eleven inclined teeth, partly surrounding its periphery, (as clearly seen in Fig. 2, side cle Vation,) leaving a space on one side. These (No model.)

teeth, as wheel 6 revolves, come in contact with a sliding rack, is, and raise it two inches,

when the teeth turn out of gear with the rack h and free it, and it drops to its first position. By this action a half-mile movement of the cups is registered, turning on arms a. By connecting the rack k by means of a wire, cord, or chain, It, with a cylinder below, placed at the center of a dial-plate, m, (see Fig. 1,) a hand on the axis of said cylinder will indicate the action. These parts are clearly explained in the drawings in Fig. 3, front and side elevation, by cylinder Z, which is an exact counterpart of that above described, but not shown in Fig. 2, the size of this cylinder being such as to make one revolution for each elevation of the rack k.

The wire, cord, or chain, instead of being endless, as seen in Fig. 3, passes once around the cylinder Z, and has a weight affixed to its end to keep it in contact with the cylindera device so obvious as to need no illustration.

The action of this instrument is as follows:-

VVhen the shaft 1) makesforty-four revolutions, the pinion e revolves one turn, and the wheel f is revolved six teeth. Ten revolutions of the pinion 0 cause a single revolution of the wheel f, making four hundred and forty revolutions of shaft 12, or half a mile of travel of the cups at the ends of the arms a, which is indicated by a single revolution of the needle on the dial m, the rack 10 being at the same time raised to its extreme elevation, where it is released from the ratchet-wheeli and drops down to the first position, to be again raised by the ratchet-wheel i.

The anemoscope consists of the usual vane and pointer. The shaft 0, like the one, b, above described, has an endless screw below, gearing into a twenty-four-toothed worm-wheel, p, on a horizontal shaft, 10, carrying-a forty-eight toothed wheel, q, that gears into a pinion, r, of twelve teeth on a parallel shaft, 1", bearing a wheel, u, that gears into a pinion, v, on the shaft 8 of a horizontal drum, 8, around which a cord or chain, 0 is wound, that connects with a cylinder, 8', the shaft Z of which is at the center of the vertical dial B, located in the cabinet A, with a needle-pointer, p, to indicate its movements. By this arrangementthe horizontal revolutions of the vane are indicated on the vertical dial B by the needle.

IOO

In conjunction with the anemometer and anemoscope I place in the annunciator case or cabinet a barometer and thermometer, at m and 3 These four instruments combined in the annunciator-cabinet constitute a signalstation apparatus necessary to forecast the weather.

In combining these four instruments so as to render them conveniently available, I employ a case or cabinet, A, Fig. 1, in which are conspicuously posted the directions for the use and application of the combined indications for foretelling the weather.

I also contemplate a further use of the cabi net as an advertising-poster, advantageous for its conspicuous position.

Havingthus fully described my improved apparatus for Weathenstation signals, I claim-- RALPH HIRSH.
