CIRCUIT-CLOSER FOR RECORDING-ANEMOMETERE.

Specification of Letters Patent.

Patented June 1, 1909.

application filed March 9, 1998. Serial No. 420,051.

To all whom it may concern:

Be it known that I, Jess (J. JUneENsnN, citizen of the United States, residing at Tappan, in the county of Rockland and State of New York, have invented certain new and useful Improvementsi'n'Ciicuitddakers for Recording-Anemometers, of which the following is a specification.

This invention relates to circuit makers for recording anemometers, and has for its object the production of mechanism of particular construction and special arrangement and operation by which an electric circuit is completed and then broken, in accordance with the movement of a revolving device acted upon by; the wind.

The object is accomplished by fashioning and associating parts as set forth in the accompanying drawings, of which- Figure 1 1s a side view of all the parts as sembled. Fig. 2 is a vertical section diametrically through the commutator box and adjacent parts belonging to a circuit-making device associated with this invention as ordinarily constructed and relating to a wind vane and means for showing the direction of the wind. Figs. 3 and .4 are horizontal sections through the commutator box on the Fig. 5 is. a front view of the large dished gear, showing different attitudes of the ball-catcher and chute. Fig. 6 'is a vertical cross-section of the gearing and a side view of the ballcatcher and chute. Fig. 7 is a horizontal section of the throat of the catcher, somewhat enlarged, showing the contact rails with which the ball makes connection.

Like letters are employed to designate the same parts throughout the specification and claims. I v

The vertical central tube or column is marked A, and it passes upwardly through a circular base or platform B which is supported uponthe tube. The base B and tube are stationary. The base has a raised center or hub provided with. a conical surface I) that forms a center bearing for the turntable C. The'weight of the turntable is supported by the base, balls c being'introduced to lessen the friction. The wind vane D is arran ed diametrically upon the top of the turnta le. The baseB has a circular series of contacts 1;, and these. are swept by the brush E, borne by the turntable and in metallic contact I with the revoluble pulley e, which is constantly in contact with the stationary disk the contacts I).

F, the disk being supported by base B. Conducting post's f pass downwardly through the base, and binding posts are provided for the connection with suitable conductors in the customary manner.

The brush E is constructed of such breadth as to be always in touch with at least one of That is to say, the brush touches the contact next in advance of it before it actually leaves the contact with which it has connection. Thus, the direc* tionof the wind may be read at any time upon any common devices introduced for the purpose, as, for example, the lamp G and letter g shownin 1.

The circuit inaker constituting this invention com rises the revolving cups H attached adjustab to arms in that are secured to the vertical shaft J that 'extends downwardly within the tube A. and has a bevel pinion at its lower end. The relatively large dished gear K meshes with the pinion and revolves upon the suitably supported stub shaft Zr. At the inner ends of its, teeth the gear K has the annulargroove or ball race L, opening inwardly toward the center of the gear. Within the groove is fixed a projecting lug or book M, which when the gear revolves serves to engage and raise a metal ball m that mov'ably occupies the groove as shown in Fig. 6; As the gear K turns the ball rises until it reaches such a position that it would fall fromthe hook and from the groove were it not for the special construction and arrangement of the ball-catcher N, which is provided with a rearwardly-extending curved apron n so situated as to cover the move L for a portion of its length. The ball 1s, therefore, constrained to remain in the groove until the mouth a of the ball-catcher is encountered. Therenpon the ball falls into the catcher and is downwardly directed by we of the throat 0 into the lower-chute P. t will be noted that the throat of the catcher is provided with the contact rails Q and R arranged lengthwise within the throat and binding posts and r are fixed upon the outside to receive any desired conductors. It is thought to borrow clear that when the metal ball passes over the rails a circuit will be completed, assuming that the interval between the rails is the only point of interru tion.

he large gear turns rapidl or slowly in correspondence with the revo ving cups H, and it is proportioned to turn once in such period of time during which the wind has caused the cups to make a redetermined number of revolutions. In ot er words, one revolution of the wheel corresponds with a certain distance moved by the wind during the same time, and the circuit is made once during each revolution.

Let it be assumed that the wind is'very high and the large gear is turning with consequently unusual speed. It is conceivable that the hook M might reach the point at which it takes u the ball, before the arrival of the ball at t e place of. meeting. This condition of things would result, clearly, in the omission of one making of the circuit. To avoid such inaccuracy, the throat and chute are ivotally mounted. It will be noted in 1g. 6 that the throat O has a lateral extension S which is centrally engaged by the end of the stationary gear shaft k.

, It will likewise be observed that the chute P has an extension 3 alined with the shaft k and rotatably supported in the bearing T. The connection between the throat and the chute is made by the two disks U and V, the latter being recessed circularly'to receive the former, and provided with a set screw 22 to hold the disks in place after ad'ustment. Now, let it be considered that the t roat and chute have been turned toward each other and into the positions indicated in Fig. 1. Under those circumstances it will be seen that while the ball has the same distance to travel as before, the hook M must move quite a distance farther in order to arrive at the oint where the chute deposits the ball, and the likelihood of an omission of the contact desired is thus avoided.

Havin now described this invention and explaine the mode of its operation, what I claim is 1. n a circuit maker, the combination with a wheel having a circular groove opening toward the center of the wheel and a hook projecting into the groove, a metallic ball adapted to travel in the groove, an adjustable ball catcher having a throat rovided with contacts arranged in the pat of the ball, and a chute disposed to continue the. throat and deposit the ball in the said groove at a lower point, substantially as described.

2. In a circuit maker, the combination with wheel having a groove opening toward the center of the wheel, a metallic ball adapted to travel in the groove, a ball catcher havlng a throat provided with contacts arranged in the path of the ball, a chute disposed to continue the throat and deposit the all in the said groove at a lower point, and means whereby the said catcher and chute may be adjusted with res ect to each other and to the said groove in t e wheel, substantially as described.

3. In a circuit maker, the combination with a wheel having a groove openin toward the center of the wheel, a metallic ball adapted to travel in the groove, a ball catcher having a throat provided with contacts ar ranged in the path of the ball, a chute disposed to continue the throat and deposit the all in the said groove at a lower point, and means whereby the catcher and chute are pivotally sup orted at the center of the wheel with t eir openin s registering one with the other, substantialIy as described.

4. In a circuit maker, the combination with a wheel having a circular groove opening toward the center of the wheel and a hook projecting into the groove, a metallic ball adapted to travel in the groove, an adjustable ball catcher having a rearwardly-ex tending apron and a throat provided with contacts arranged in the path of the ball, and a chute disposed to continue the throat and de osit the ball in the said groove at a lower point, substantially as described.

5. In a circuit maker, the combination with a wheel, of a movable body, means adapted to encounter the body and raise it as the wheel turns, devices constructed and arranged to prevent the body from leaving the wheel laterally, an adjustable catcher rovided with contacts disposed in the pat of the body, and a chute arranged 'to receive the body falling from. a higher point on the wheel and to deposit the body on the wheel at a lbwer point, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
