MACHINE FOR GATHERING STONES.
EPECIPICATION forming part of Letters Patent No. 300,173, dated June 10, 1884. Application filed May 17, 1883. (No model.)
To all whom it may concern.-
Be it known that I, BRAYTON ERBEE, a citizen of the United States, residing at Warren, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Machines for Gathering Stones, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to machines for gathering stones, and it consists in certain improvements in the construction of the same, as hereinafter shown, described, and claimed.
My invention has chiefly for its object to construct a machine for gathering stones which shallcontain, first, an efficient picking device for loosening stones in the surface of the ground, and thus facilitate the operation of the gathering devices; second, a revolving propelling device by which the stones are propelled or driven from the ground into abox or receptacle suitably located to receive them, guides being provided to direct the course of the stones to the receptacle; third, mechanism for supporting, adjusting, and regulating the propelling device in position, said mechanism being automatic in operation, thus ren dering the revolving propeller self-adjusting Stone gathering machines as heretofore constructed and used have been provided with elevating devices for taking up the stones; but a machine constructed with my improvements accomplishes the object in a different manner, the stones being propelled or driven from the ground by a revolving propeller into a receptacle provided for them, and the oper' ation being rapid and effectual.
In the accompanying drawings, Figure 1 is a side view of a stone-gathering machine having my improvements. Fig. 2 is a plan of the same. Fig. 3 illustrates in perspective the picking device. Fig. 4. represents a transverse section of the revolvingpropeller. Fig. 5 represents the inner side of one of the propellerheads. Fig. 6 illustrates the propelling-teeth. Fig. 7 shows the manner of attaching the propelling-teeth. Fig. 8 illustrates the arms and pivotal bearings of the propeller-shaft. Fig. 9 shows different positions of propelling-teeth.
Fig. 10 is a partial side and sectional eleva- A. WEATH- ing the inclined hinged apron.
tion illustrating the stone-gathering apparatus.
Fig. 11 illustrates the teeth or sections form- Fig. 12 is a transverse section showing a form of propeller used for large stones. Fig. 13 represents one of the swinging guides used in connection with the sectional apron. Fig. 14 is a rear perspective view. Fig. 15 illustrates the sectional apron in perspective. Fig.- 16 illustrates the toothed gearwheel through which power is transmitted.
A designates the frame of the machine, and
B the main driving-wheels.
0 indicates the front wheels of the truck, the axle G of which hasalink-conncction with the bolster 0 above it by means of two eyebolts connected at the eyes and one passing through each part, as shown, and the wheels 0 being small enough to turn under the pieces 0*, connecting the bolster with the main frame, the truck may be readily and quickly turned.
D indicates a number of pickers, which are hinged to the machine at its forward part by means of a fixed rod, to, passing through them at their upper ends, the lower ends being provided with teeth I) and resting on the ground. These pickers D are placed forward of the stone-gathering apparatus, and serve to loosen the stones in the surface of the ground, so that they are more readily caught by the apparatus in the rear. The pickers may be raised from the ground, as desired, by any suitable means, those shown being a bar, a, placed transversely under the pickers and connected by cords or rods with short arms on a shaft, a", passing across the machine at the front end, and operated by means of a lever, a
E represents a sectional drag-apron formed of straight teeth 0, each tooth having a loose connection at its front end with a rod, d, fastened at each end to the frame of the machine at the bottom, the rear end of the tooth trailing on the ground. The apron is in an oblique position,with the free ends of the teeth resting on the ground, and serves to guide the stones and fragments thrown forward by the stone-propelling device-into the box or receptacle F, and prevents the stones going under the same during the operation herein described. Each tooth 0 having an independent movement as the apron passes over the stones, each tooth may be lifted singly by a stone over which it passes, so that the inclined plane formed by the apron generally keeps its j endwise,
position. The teeth forming the apron may be raised simultaneously by means of a rod or bar, a, passing under the apron, said bar having an elbow at each end,and being connected at one end with a pivoted lever,
The swinging guides E, one being placed at each side of the apron E and extending rearward, are used in connection with the apron in directing the course of the stones as they are driven forward by the stone-propeller. The said guides are loosely suspended to the frame-work on the inner sides by the straps (1, so that their lower edges nearly touch the ground. They have a swinging movement so that in case of contact with any obstacle the swinging guide rises, and thus avoids damage, and a guard,-d fixed to the frame, serves to keep the guide in place, and prevents it swinging too far forward.
The gathering of stones is effected by means of a propelling device provided with teeth or beaters the strokes of which send the stones from the ground. into the receptacle F.
G indicates the disks which form the heads of the revolving propeller, which is on a shaft, 6, said disks having formed on their inner sides the seats or recessesf, to receive the square ends of the bars 9.
To the bars 9 are removably secured the propolling-teeth h in the following manner: A groove, 2', is formed in each bar lengthwise, and the inner end of each strip forming a tooth is bent at a right angle and is inserted in the groove. (See Figs. 6 and 7 The strip is then secured to the bar by a strap, h, fastened to the bar by bolts and nuts, the bolts entering between the strips forming the teeth,
' so that the latter may be readily removed as desired. \Vhen the barg is made of wood, the groove i is usually provided with an iron lining. The bars 9 are also removable, the seats f in one of the disks G having each a re movable flange, k, which is secured in place by bolts and nuts. Either of the bars 9 may be taken out by detaching the flange 70 at the end of it. (See Fig. 5.) The propelling device on shaft 0 is so adjusted in position that when it is rotated the points of the teeth pass near enough to the ground to strike the stones, the strokes of the teeth being forward, so as to drive the stones in the direction in which the machine is drawn. The propeller being rap-- idly rotated, the stones are struck suddenly and forcibly by the teeth, and are effectually driven forward to the stone-receptacle without any other conveying or elevating devices. As shown in the drawings, (see Fig. 7,) each strip forming a tooth it passes from the point of its attachment once around bar g, hugging the bar and then straight outward, with any desired form of point at its outer end, (see Fig. 6,) a spring-tooth being thus formed which is very efficient in propellingthe stones into the box or receptacle. The spring-teeth may be set in either of two positions, as illustrated in Fig. 9. When adjusted in position readily effected by simply reversing the position of bars 1, having the teeth attached.
The shaft 6 of the revolving propeller-has its bearings in the arms H, one of which is on eachside of the machine, and has a pivotal connection at one endj with the axle of a driving-wheel B. A short arm, Z, projects downward from each arm H, the curved arms at being pivoted thereto at n, and being also adj ustably secured to arm H by bolt. at n.
A shaft, 0, of ground-wheels I has its bearings in the curved arms m, the arms H being thus supported and regulated in position. The rear extremities of said arms H are connected by arod, K, which is provided with knucklejoints :0. J is an opening in each of the arms H, within which is placed a box, 12, in which the shaft 0 of the revolving propeller is jour naled. Two short arms or trunnions, 1), extending laterally from the box 1), enter sockets formed in arm H, the parts being so construct ed as to allow the box 1) a lateral movement,
and also a rocking movementlengthwise. The
lateral movement is to allow shaft 6 to be moved in and out of gear, and the rocking movement is to prevent any binding of the shaft in passing over uneven ground. The opening J is made larger on one side of arm H, to allow the insertion of journal box p, which, when placed, is. secured by pieces p bolted to the arm H, as shown. As will be seen from this construction,the arms H, carrying the propeller, have their center of movement in the axles of driving-wheels B, and said arms, being supported by arms m and ground-wheels I, are raised or depressed as said wheels pass over surfaces where the ground is not level, the revolving propeller making the same movement, and thus keeping a uniform proximity to the ground, so that the propelling-teeth strike the stones, which are effectually driven forward, whether the surface of the ground is level or uneven.
On each end of a shaft, L, having bearings at the top of the frame, is an arm. M, the same being attached at or near its center, and such attachment being either rigid or in such a manner that a rocking movement of one arm M imparts a like movement to the arm M on' A rod, N, connecting with the opposite side. each arm H at g, has its upper end connected in an elongated aperture or short slot, 0'', with the rear end of an arm the arms M and their connections is to provide for the automatic adjustment of the re volving propeller as the machine moves forward. hen one ground-wheel I is elevated by rising ground which does not affect the other wheel, one arm H, and consequently one is also raised, and the end of the propeller,
connecting-rod N raises the rear end of an arm M. A like movement is immediately impart M. The purpose of I" ed through shaft L to the opposite arm M, and
this arm being also connected with the oppowith arms M allow a slight irregular movement of the propeller, as a slight rising or falling of either end of it.
For the purpose of moving the revolving propeller in or out of gear, an eccentric, P, is placed on each end of a transverse rod, 0, having bearings s, held by arms H, near their outer ends, said rod being usually provided with knuckle-joints s. A removable rod, 8 connects each eccentric with the end of the shaft e of the revolving propeller, and by a movement of a lever, Q, at one end of rod the shaft 0 may be moved sufficiently to move the gear-wheel R on said shaft either in or out of gear with the large gear S, fixed to the axle of the driving-wheels B, the movement being allowed by the construction of the journal-boxes 2 p and arms H, as above stated.
Motion is imparted from driving-wheels B .to the revolving propeller by means of ratchets and spring-pawls V on axle and drivingwheels, and gear-wheels S and R. A set of gears R and S may be employed at each end of driving-shaft, if deemed advisable. The teeth of these gear-wheels are of peculiar construction, being made somewhat rounded and bulging horizontally at the middle, as shown in Fig. 16. The object of this form of teeth is to allow somewhat for a little variation between the movements of the revolving propeller and the driving-wheels, and prevent any interruption of the connection between gearwheels R and S.
A pole, T, forming a lever, with its fulcrum t at the top of the frame, has its rear end connected with the rear end of one of the arms M, the forward end of said arm being also connected at t with the pole which is intended for the driver, who may by a movement of the pole move both arms M, and thus raise the propeller as desired.
U indicates a small V-shaped scraper having an arm, a, pivoted to the frame of the machine. One of these scrapers is placed forward of and on a line with each driving-wheel, to keep a clear track for said wheel, a fixed guard, 10, serving to retain it in place, and allowing it a limited vertical movement in case of contact with any obstacle. The scrapers U may be raised from the ground as desired by means of a foot'lever, W, on a shaft or rod, u, across the front part of the machine. At each end of said rod is an elbow or crank-arm connected by a rod, a with one arm of a bellcrank, 12', pivoted to each side of the machine, the other arm being connected, as shown,with the arm a of the scraper, and by pressing the lever downward the driver raises the scrapers.
As the machine is drawn forward, the pickers D loosen any stones sticking in the surface of the ground, so that they may be readily reached by theteeth of the propeller. The inclined apron following passes over the stones, and from its sectional construction, as above stated, mainly keeps its parts in position. The propelling device in the rear,receiving motion from the driving-wheels through the gearing, as set forth, is rapidly revolved, and its elevation being properly adjusted by means of the curved arms m the points of the teeth h pass very near the ground, striking the stones and propelling or driving them to the receptacle F, carried by the frame, and any stones that may be driven or'thrown in an indirect or diagonal course will strike either the inclined apron or the guides E, and are directed to the stone-receptacle.
For the purpose of gathering large stones a set of bars, 9, having firm, straight teeth fixed thereto, as shown in Fig.12, is provided, the
teeth h being passed through the bar g and held. The bars 9 and g are used interchangea bly as occasion requires, the changebeing effected by simply removing one set of bars from the revolving propeller in the manner described, and substituting other bars with the other form of teeth. As the teeth h are made shorter than the teeth h, it may be necessary to set the bars 9 farther from the center of the propeller, and to answer the purposes of both bars 9 and g the heads G may be constructed with two sets of recesses or seats for the ends of bars, as shown in Fig. 12, in which four seats f are intended to receive bars g, and four f to receive bars as may be desired. A curved apron (indicated at X) forming a guard and extending rearward is usually secured to a cross-bar, Y, of the .main frame, and another guard, Z, is also secured to the frame-work, so that it is held in position under the gear-wheel for the protection of said wheel.
Having described my invention, I claim- 1. In a stone-gathering machine, the pickers D, placed forward of the stonepropelling apparatus, for loosening the stones, and having independent hinge-connection at their forward ends with the frame, in combination with the revolving propeller arranged in rear thereof, substantially as set forth.
