Figure 1 is' a side elevation of one em! bodiment of the invention;

Fig. 2 is an end elevation of the same;

Fig. 3 is an end view of the car appearing in Fig. 1; I

Fig. 4 is a sidey elevation of another embodiment of the invention.

In carrying. out my invention, I employ a substantial supporting frame 1 which may be of any desired construction and is erected or built at the side of or adjacent the flowing stream of material to be sampled. Upon this supporting frame-is journaled a longitudinal drive shaft 2 equipped at one end with a band pulleyB. which may be driven from any -convenient or preferred prime motor and in Fig. 2 is illustrated as cone nected by a belt 4 with a driving pulley 5. Upon the shaft 2 between the center and the ends thereof, I secure or form worm 6 which have their threads oppositely dis'- posed, as clearly. shown in Fig. 1. These worms mesh with worm gears 7 and 8 which are mounted loosely upon shafts 9 suitably journaled upon the supporting frame and each worm gear is provided on one face with a lateral lug 10 adapted to impinge against a similar lug 11 on the opposed face of a wheel or disk 12 which is fixed upon the shaft adjacent the worm gear. The Wheel 12 is provided on its periphery with a cam or projection 13 and also carries a weight 14 upon one of its spokes and on one end of each shaft 9 is secured an arm 15 having a Weight 16 adjustably fitted thereon. The weights 14 and 16 act in unison but are disposed upon different radii of the shaft so thatI they,v will overcome all dead centers and the operation of the machine will bev certain at all times. Fulcrumed upon the supporting frame, midway Specification of Letters Patent.

between the two shafts 9 and above the hori- '/.ontal plane of the same, is a shaftv or rod 17 upon which is mounted a lever 18, the

lower end of the lever being equipped with a roller 19 which is adapted to be engaged by the projections or cams 13l of the'two lwheels alternately and the upper end of the lever being connected by a pitman20 with a sampling car 21. It will be noted upon reference to Fig. 1 that the upper arm of the lever is very much longer than the lower arnr thereof so that the throw of the lever will be amplified andthe car 21 moved a sufficient distance to pass across the stream from which the sample is taken.l In Fig. 1 the car is illustrated as arranged to pass across the stream and is mounted upon an arched track 22 so that when the car has moved over the crown or apeX of `the track, which should preferably 'be at the center of the stream, the incline of the track will aid in holding the car in the position to which it has moved until the -driving mechanismg again posltively acts` on the car to return of a storage receptacle into which the material will flow automatically but, in any event, it should have an open top of such length that the chute will be; over the same il in all its positions.

The operation of the machine will, 1t 1s thought, ibe readily understood. The vibrating lever is mounted in the vertical plane of the wheels 12 which are secured on the respective shafts 9 while the worm gears 7 and 8, as stated, are loosely litt-edupon the shafts and rotated in opposite directions. The lugs 10 upon the respective worm gears 'are arranged upon different radiiof the respective shafts 9 and the projections 13' upon the wheels 12 are so arranged that the projection on onewheel cannot engage the roller 19 upon the lever at the same time that the roller isengaged by the projection or cam upon the other wheel. Assuming that the shaft 2 is rotating, the worm gears 7 and 8 will be turned in opposite directions about the respective shafts 9 but the wheels 12 will normally be at rest. Asthe lug 10 upon the gear 7, for instance, comes into contact with the lug 11 upon the adjacent wheel 12 it will transmit motion to the said wheel and the shaft 9 so that the weights 14 and 16 will be raised. As soon as the weights pass beyond the vertical plane of the shaft 9 they -will immediately begin to drop. and will accelerate the motion of the wheel 12, the lug 11 leaving the lug 10 and the cam or projection'13 being carried quickly into engagement with the roller 19 upon the lever 18 and riding on and past the same so that the lever will be quickly swung' froml the position shown in full lines to the position shown in dotted lines in Fig. 1. The car 21- will, of course, be moved across thestream and will remain in the position to which it is thus moved until the cam or projection 13 upon the wheel 12 c'ooperating with the worm gear 8 vis brought into engagement with the roller 19, whereupon the lever will be given a reverse oscillation and the car returned to its initial position. The speed of the worm gears is steady and uniform but it will be readily noted that the lever-actuating wheels or disks move rapidly when acting upon the lever but move more slowly between the actuating periods, the movement during the actuating period being due to the gravitating force of the weights 14 and 16 while the intervening movement is due to the engagement of the lug 10 of the worm wheel with the lug 11 on the lever-actuating wheel.

I thus move the car across the stream rapidly so that there will be no choking of the same and then provide an interval of rest for the-car so that the samples will be taken at regular periods and an average value ascertained. By properly regulating the speed of the driving shaft 2, the periods intervening between the taking of samples may be lengthened or shortened as desired.

The arm 15 with its weight 16 constitutes a pendulum having a tendency to oscillate 1n both directions when once set in motion.

To arrest the pendulum and prevent backward movement thereof which would result 1n damaging contact between the lugs 10 and 11, I provide the. racks 27 below and concentric With the pendulums having teeth 28 on their upper. sides and on the ends of the arms 15 are dogs 29 which will ride over the teeth 28 in the forward movement ofthe pendulum but will engage against one of the teeth when the pendulum attempts to pendulum will consequently be held at the upper limit of its forward movement until the lugs 10 and 11 are again properly engaged.

In Fig2 4 have illustrated any arrangement whlch l1s especially adapted for use under conditions which require that the car move endwise into the stream or bank from which asample is to be taken, it being evident that it is necessary in such event for the car to be immediately withdrawn. In this arrangement, the lever 30 corresponds in all respects with the lever 18 and is connected by a pitman 31 with the car 32. That section of the machine which is shown at the right in Fig. 1, however, will be omitted and only one section employed, the operation ofthe section being to drive the car into the bank. To withdraw the ca'r from the bank, I erect a post or anchor 33 adjacent the bank and extend a cable 34 between the upper end of the post and the end hangers 37 from the car body but is arranged longitudinallythereof instead of transversely as in Fig. 3, the upper end of the chute projecting beyond the adjacent end ofthe car, and the lower end of the chute discharging into a hopper 38.

My improved machine is simple in the construction and arrangment of its parts and can be installed and operated at a low cost. When in operation it will be positive in its action and certainvin its results.

Having thus described the invention, what is claimed as new is:
