UNITED STATES JACOBSCHRAG, OF ROCHESTER, NEW YORK.
MACHINE FO'R PICKING UP AND COLLECTING STONES.
Application filed January 8, 1925. Serial No. 1,165.
To all whom it may concern:
Be it known that I, JAooB SGHRAG, a 0151' zen of the Republic of Switzerland, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Machines forIicking up and Collecting Stones, of which the following is a specification.
The object ofthis invention is to'provide a new and improved machine for picking up stones from a plowed field, so that the stones can be removed from the ground. Another object is to separate stones from dirt and return the dirt to the ground.
These and other objects of the invention will'be illustrated in the drawings, described in the Specification and pointed out in the claims at the end thereof.
:In the drawings Figure 1 is a side elevation of my improved machine.
Figure 2 is a section on the line 2?, 2 of Fig. 1.
Figure 3 is a section on the line 3*, 3 of Fig. 2.
Figure 4 is a rear elevation of the machine. I
Figure 5 is a top plan of the front portion of themachine.
Figure 6 is a front elevationof the front of the machine.
In the drawings like reference numerals indicate like parts.
In tliedrawings reference numeral 1 indicates the frame of the machine made up of beams 2 and 3 whichv are connected together by the yoke 4. at the front and are fastened to the box 5 at the rear. At the front of the machine is provided the axle 5 on which are swiveled the spindles 6 and 7 which in.
turn are supported by the wheels 8 and 9. n the axle 5 is provided the. four guide rods 10, 10 and 11, 11 each of which have a reduced endv at the bottom whichpass through suitable openings in the axle 5. These guides 10 and 11 are arranged in pairs as shown in Figure 5. Each guide has a shoulder which rests upon a plate 12 which in turn rests upon the axle 5. A similar plate or washer13 is shown below the axle. The lower ends of the guide rods are riveted up as indicated at 14 by which they are firmly held in place.
The beams 2 and 3 are provided with guide sleeves at the forward end which engage with two of the guide rods 10 and 11 so that they can move up and down thereon.
Itwill be understood that while a pair of rods 10 and 11, llare provided on'each side, the beams engage with only one rod of each pair. make the structure more rigid. On top of the rods 10 and 11 is provided a bridge 15. On the forward end of the yoke: 4 is provided a hanger 16 with which engages the screw 17, which extends up to the bridge 15. A
hand wheel 18 engages with this screw and is threaded thereon and rests on the bridge 15. As the hand wheel isturned the forward ends of the beams are raised or lowered so as to hold them at. a suitable distance At the rear end the above the ground. beams are attached to the box'5 which box is provided to receive the stones thatare picked up off of the ground and carry them ofi the field. .The beams are supported by The two extra rods are used to an axle 20 which in turn is supported by the wheels 21 and 22, which rest on the ground.
The axle 20 passes through the box 5 from one vwheel to the other. On each of the wheels 21 and 22 are carried sprocket wheels 23 and 24. The sprocket wheel 23 drives the chain 25, which in turn drives the sprocket wheel 26 carried on the shaft27. The shaft 27 rotates in a bearing which is supported on the cleat 28 which cleat in turn is supported by the angular bracket'29' and 30. The sprocket wheel 26 and shaft 27 drives a pinion 31 that in turn drives a pinion 32 carried on a shaft 33. This shaft. carries sprocket wheels 3% and 35 which in turn drives the chains 36 of an endless conveyor which at its lower end passes over a similar sprocket wheel supported on a shaft 37. which shaft rotates in bearings supported by the triangular bracket 38. The endless conveyor of which the chains. 36 form a part travels between guides 39. At suitable intervals these chains are connected by cross bars 40, which bars travel over slats ll which form the bottom of the runway of which the guides 39 form a part. The chains and cross bars comprise an endless conveyor.
The sprocket wheel 2% drives a chain 12 which in turn drives the sprocket wheel 43 carried on the shaft i l mounted to rotate in suitable bearings 15 carried on the triangular bracket 29 and 30. This shaft is provided with sprocket wheels 16 and 47 shaft 50. is supported between the bearings 51 which are attached to the under side of the beams 2-and 8. The chains 48 have attached thereto at suitable intervals triangular plates 52 which plates form a part of the chain. On the point of these plates is pivoted the swinging arms which arms support blades 5% on the bottom thereof that are substantially as wide as the conveyor 40. To these arms are attached links which pass up through the double links of the-chains 48. The upper ends of these links are upset so as to positively engage over the links of the chains and by them the downward movement of the links 55 is limited so that the arm 53 can swing do to the position shown in Figure 3 and on the lower side of the conveyor as shown in Fig. 1, but cannot swing below that position and is, always free to swing above this position as is shown in the upper run of the conveyor 4:8 in Figure 1. This swinging, arrangement permits the blades to yield iffthey should dropv on top. of a rock so that jamming is avoided, but enables the blade to take hold of the rocks whenever they drop down behind the rocks. There will be some tendency of rocks-to roll down the conveyor 36, 0 and such movement of the rocks will be arrested by the blades 54. It will also be understood that the gearing that drivesthe conveyor 36, lO will drive it at a velocity considerably higher than the velocity at which the blades 54 are carried up. This is apparent from an inspection of Figures 1 and 4. Figure 45 shows that the sprocket wheel 23 is of large diameter and the sprocket wheel 26 is of small diameter and this in turn drives a large pinion 31 which drives a small pinion 32 which in turn drives the lower conveyor. This gives the lower conveyor a high velocity. Figure at shows that sprocket wheel 2-l is of small diameter and this in turn drives sprocket Wheel at?) which is of larger diameter than sprocket wheel 26 and this sprocket wheel 43 directly drives the shaft 414: that drives the upper conveyor. This gives the upper conveyor a low velocity.
As shown in Figure 1 a bracket is provided on the under side of each of the beams 2 and A bracket 61 is also provided and from these brackets is supported a rake 62 two of which rakes are provided as is shown in Figure 5. These rakes liare out forwardly so that they cover a width several times aswide as the conveyor and by these rakesstones are deflected inwardly into line with the conveyor so that all stones caught thereby will be landed on a shoe 6?) as shown in Figure 5. Whatever stones land on the shoe will be caught by the blade and will be carried up thereby and thrown on the lower conveyor, which carries them forward at a high rate of speed and will separate the dirt from the stones, the dirt falling through between the cross bars oi the conveyor and between the slats ll, *ll while the stones are carried upward and are dumped into the box 5.
I claim:
1. In a machine for picking up stones, the combination of a frame, a pair of endless inclined conveyors mounted 011 said frame, the upper conveyor being longer at the lower end than the lower conveyor, a stationary shoe at the lower end of the lower conveyor adapted to pick up stones and place them on the upper side of the lower conveyor, the upper conveyor running in the reverse direction at a lower speed than the lower conveyor and having blades thereon that cooperate with the lower conveyor and move in the same direction with the upper sideof the lower conveyor to raise stones and separate them from dirt and discharge stones into a receptacle, said blades being mounted to swing on said upper conveyor and means carried by said blades to hold said blades at a predetermined angular position with relation to said conveyors to allow the stones to pass under said blades and scrape the surface of them.
2. In a machine. for picking up stones, the combination of a shoe for picking up stones, an endless conveyor on which said shoe is adapted to discharge stones, said conveyor running rearwardly and upwardly, an upper conveyor mounted parallel with the lower. conveyor, the under side of the upper conveyor running in the same direction as the lower conveyor, and at a much lower speed than the lower conveyor, blades mounted to swing on the upper conveyor and cooperate with they lower conveyor to carry stones up thereon an arm carried by each of said blades said arm extending from the blades to said upper conveyor and means provided on said arm to hold said blades against movement in one direction but allow the blades to swing in the opposite direction against the under side or said upper conveyor.
In testimony whereof I atlix my signature.
