WIND-DIRECTION AND WIND-VELOCITY INDICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 764,759, dated July 12, 1904.

Application filed August 21, 1903.

To all whom it may concern.-

Be it known that I, GEORGE ALFRED OWEN, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in ind-Direction and Wind-Velocity Indi eating Apparatus, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for indicating the direction and velocity of the wind and also to non-automatic means combined therein for making an indication or record of the direction of the wind to be re- .ferred to at a time subsequent to the making of such indication.

The object of the invention is to provide means at the top of a building subject to the wind-currents and afiected thereby both in respect of direction and velocity operatively controlling index-pointers movable over the face of a dial understood as located in any convenient and conspicuous place within thebuilding, said dial having wind-direction and windvclocity characters with which the pointers variably register and with regard to simplicity in organization and reliability in action.

The invention consists in the construction and arrangements of parts, all substantially as hereinafter fully described, and set forth in the claims.

In the drawings, Figures 1 and 2 together show in vertical section the exteriorly and interiorly located parts of the apparatus and the operating connections between the former and the latter. Fig. 3 is a face view of the interiorly-located indicator. Fig. 4 is a perspective view in detail of parts shown in the sectional view, Fig. 2. Fig. 5 is a perspective representation of equivalent driving connections to those shown in Fig. l. I

Similar characters of reference denote corresponding parts in all of the views.

In the drawings, A represents the weathervane and in suitable and approved form, the same being secured at the upper end of a shaft B, fitting a rotatable within a tubular post O, mounted on the top of the building. Pivotally mounted on and between the divergent Serial No. 170,292. (No model.)

members a a of the weather-vane is a cupshaped wind-baffle member D.

A sheave Z) is affixed at the lower end of the weather-vane shaft B within the building, said. sheave being rotatably in unison with the shaft in ahorizontal plane and mounted on a bracket d within the building, and adjacent the sheave b is another sheave, g, rotatable ina vertical plane and having its rim about tangential with the axis of the shaft B, and a guide-sheave it is also supported by the weather-vane for r0- tation in a vertical plane above the open end of the tubular shaft-and with its rim located about tangential to the axis of the shaft.

E represents the indicator, the same being understood as located at any suitable and conspicuous place within the building, having a wall 3' therein, thefront of which constitutes a dial, as seen in Fig. 3, having thereon the wind-direction characters N, E, S, and W., and intermediate wind-directionindicating characters and marks, as desired, and also on the face of the dial in circular arrangement are wind-velocity figures, as seen,

forward end the long index or pointer m to register with the wind-direction characters and having at its rear end the sheave n.

A cord or other form of light endless driving-band 0 has a running engagement around the sheave Z) on the weather-vane and around the said sheave a in the indicator casing, the same being intermediately guided for changing the direction of the courses of the drivingband from the horizontal to the vertical around the guiding-sheave-p, located within an angular hollow fitting q, understood as being provided at or near the roof of the building and downwardly open therethrough.

The aforementioned shaft or arbor /r; for

v the pointer m and the shaft a form as one therewith are axially bored to give bearing therethrough for the short shaft r, which has at its rear end the double sheaves s s and by its forward end the wind-velocity pointer t, which is arranged to register with the circularly-arranged wind-velocity characters.

Attached to the wind-baffle member D is a cord 24, having a running engagement around sheave h, centrally down through the tubular Weather-vane shaft, thence around the guidingshaft 9, thence horizontally under the roof of the building to and around a guidingsheave p p adjacent to the aforementioned sheave p, and thence toan operating engagement with the sheave s, all whereby the amount of movement which the more or less rapidly-blowing and correspondingly-strong wind imparts to the member D will cause a registration thereof by the pointer 26 on the wind-velocity figures on the front of the dial. In order that the wind-bafiie member may be restored to its normal position upon the decrease in the wind force and the pointer 6, also a spring a has an engagement for reaction on the sheave a 8 which is understood as afiixed the same as sheave s on the shaft 1''.

The indicator-casing is provided with a glass front G, and the casing has the surrender-flange w, on which movably engaged is a clip or yoke as, having an inwardly-extending index-pointer a: 0

Time-indicating characters are provided at the front of the indicator either on the dial behind the glass or directly on the glass front.

Hands y y, like the minute and hour hands of a clock, are arranged on a sleeve or shaft, one fitting through the other and both centrally arranged through a bushing in the center of the glass front, the hands being disposed on the inner ends of their respective shaft, the outer ends of which have handleknobs y whereby the hands may be turned from the outside to indicate any given time.

It is therefore possible for a person. upon noting the direction of the wind at a given time to slide the index-yoke :1: so that the pointer registers with the wind-direction character corresponding thereto and setting the time-indication hands in relation to the Roman characters to designate the time of such wind condition. This may be habitually done, for instance, at twelve oclock of each day, so that at any subsequent time on an inspection of the indicator it may be known what was the direction of the wind at such given time.

The operating-cords 0 and a may have the courses thereof between the different sets and sheaves with which they coact inclosed within tubular casings, as partially indicated at z in Fig. 2.

The cup-shaped member D, which receives the wind impact by being mounted on and bodily movable with the weather-vane, be-

- sides having its individual independent movebearing wind direction and windvelocity characters, separate pointers cooperating re:

spective] y with said characters, and independent flexible connections between said vane and battle member and their respective pointers.
