SEEDING-MACHINE.

SPEGIFIATIION forming part of Letters Patent No. 676,92 5, dated lune 25, 1901.

Application filed May 29, 1899. Serial No. 718,666. (No model.)

To LZZ whom, t may concern:

Be it known that we, IRVING D. STEVENS and CHRISTIAN GRAY, citizens of the United States, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Seeding-Machines; and We hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it apper tains to ymake and use the same.

This invention relates to seeding-machines, and especially to that class denominated end-gate seeders, which are adapted to be mounted upon the end-gates of wagons. In machines of this character power is transmittedto the driving-shaft of the seeder by a chain running from a sprocket attached by clips to the wagon -wheel over a smaller sprocket mounted on a drivngshaft and thence by beveled gears to the operating mechanism of the seeder, a clutch mechanism being employed to connect'and disconneet the seeder mechanism and the drivingshaft. In machines as heretofore constructed it is customary to mount the movable mem-v ber of the clutch mechanism fast upon the driving-shaft or to have this member consti` tute the small sprocket, so thatin either case the sprocket is shifted laterally as the clutch is thrust for engagement and disengagement. These arrangements are objectionable, as the shifting of the parts causes the sprocket-` wheels to move out of alinement, thereby causing unnecessary Wear upon the chain.

One of the objects of our invention is to obviate this objection, which we do by providing a construction in which the alinement of the sprockets is maintained in either position of the clutch mechanism.

Another object of our invention is to provide a seeder having an automatic feed cutoif, so that when the machine is out of gear no cast `can be made, thereby insuring that no seed shall be wasted.

A further object of our invention is to provide a machine of this general character in which the size of the seed holes or ports may be reduced from the outside toward the ceuter, so that the area of the openings shall approximate more nearly to the center of the distributer as they are reduced in order to make a more uniform and even cast of smaller seeds.

Another object of our invention is to provide a device of this kind in which the hopper may be readily attached and detached.

Other and further objects of our invention will appear from the disclosure hereinafter made.

In order to accomplish the objects for which the machine is designed, our invention con sists in the constructions, arrangements, and combinations of parts hereinafter fully set forth in the specification and specifically pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a perspective View of the seeder mounted on the end-gate of a wagon with the clutch mechanism engaged to operate the seeder mechanism. Fig. 2 is a top plan of the same with the hopper removed. Fig. 3 is a vertical cross-sectional view with the clutch engaged. Fig. 4: is a side elevation with the hopper in section. Fig. 5 is a detail view of the clutch mechan-A ism disengaged. Fig. 6 is a detail sectional view ou the line 6 (i of Fig. 5. Fig. '7 isa de tail plan view of one of the valves. Fig. 8 is a plan view with the hopper removed, showing the arrangement of parts when the clutch is disengaged. Fig. 9 is a central transverse sectional view on the line 9 9 of Fig. S.. Fig. 10 is a longitudinal plan view on the line 10 l0 of Fig. 8, and Fig. ll is a plan of the feedhopper.

The same referencefletters indicate the same parts throughout the specification.

In the drawings the letter A indicates the large sprocket, which is attached to the wheel of the wagon on which the seeder is mounted by means of clips Cc. As shown, three of these clips are used, and they secure the sprocket by passing around three of the spokes of the wheel. Passing over this sprocket is the gearchain b, by which power is transmitted to the small sprocket t', which is keyed on the driving-shaft B. This shaft is supported in suitable brackets b2 b3, which are attached to the end-gate of the wagon by bolts. The end bracket b2 has an arm that projects laterally and rearwardly, terminating in the bearing IOO b4, in which one end of the shaft B is journaled, the other end being journaled in the bracket b3. This bracket projects rearwardly from the end-gate a distance sufficient to bring its horizontal bearing b5 in line with the bearing h4 of the bracket b2, so that the shaft B is held in such relation to the endgate as to give room for the rotation of the gear-wheel C, which is sleeved on the shaft, as will be hereinafter fully pointed out. The bracket b3 is provided with a vertical bearing b, in which the vertical shaft d of the distributing wheel or fan D is stepped, as will be more fully described. The shaft B is held against lateral movement by the small sprocket b', which is keyed to it at one side of the bearing b4, and by the ring b?, which is keyed to it at the opposite side of this bearing,

as clearly shown in Fig. 2.

The gear-wheel C is cast with an integral hollow sleeve c, which surrounds the shaftB` and is journaled in the bearing b5, as clearly shown in Fig. 3. This sleeve is held in place and prevented from moving laterally byv means of the ring c', which is keyed to the sleeve c in such manner as to bring the bearing b5 between the ring and the hub of the gear-wheel.

When the shaft B is rotated through the agency of the sprockets and chain, the gearwheel C may or may not revolve with it, according as the clutch, by which it may be locked to the shaft, is shifted into or out of engagement. The mechanism for this purpose is clearly shown in Figs. 3, 5, and 6. The gear-wheel is provided on its front face opposite the sleeve c with a laterally-projecting lug c2. A spring c3 is coiled loosely about the shaft, being held in position between the face of the gear-wheel and the pin c, which passes through the shaft B. The ends of the spring are carried out tangentiallyto the shaft and formed into oppositely-disposed hooks c4 o5, as shown in Fig. 6. The hook cL1 is in the path of the lug c2, and the hook c5 is in the path of the travel of the flange c2 of the clutch E when the latter is thrust into engaged pcsition for purposes hereinafter pointed out. The arrangement of parts is clearly shown'in Figs. 5 and 6.

The clutch F. is sleeved loosely onthe shaft B and is shifted lengthwise of the same by means of the lever F, which straddles the clutch in a well-known manner, whereby the latter may freely rotate with the shaft, but be controlled in its movements along the shaft by the lever. This lever is pivoted upon the bracket h2 by means of the rearwardly-projecting pin f', which is cast integral with the bracket and receives the sleeve f2 of the lever. The lever is carried forwardly near its upper end and terminates in an upwardlyprojecting handle f3, arranged in proximity to the hopper for a purpose hereinafter xset forth. The clutch is provided on its face with two oppositely-arranged projecting studs c e', which extend across the face of the clutch,

so as tocoine close to the shaft. The periphery of the clutch is somewhat enlarged at the point of attachment of the stud e, so that the latter projects a distance beyond the path of the travel of the stud e. The stud e is provided with a tiange e2, projecting from the face of the clutch at the point of its greatest diameter. By this construction and arrangement of parts when the lever F is operated to thrust the clutch into engagement the studs e c are carried into the path of the travel of the pin c, which revolves with the shaft, to which power is applied by the sprocket-andchain connection. As the shaft revolves from rear to front, as indicated by the arrow in Fig. 2, the pin c6 engages the studs e c' of the clutch E and causes this member to revolve with the shaft. The flange e2 of the stud e' projects beyond the pin cG by reason of the enlarged peripheryof the clutch at this point and extends into the path of the hook c5 of the spring c3, as shown in Fig. 5, so that the latter is caused to revolve with the clutch and shaft, and by reason of the engagement of the hook c4 and the lug c2 of the gearwheel the latter is in turn rotated to transmit motion to the operating mechanism of the seeder with which it is geared. When the Vclutch is in turn thrown out of engagement, the parts become disconnected by the disengagement of the pin c6 from the studs ec and the flange e2 from the hook c5, so that the rotation of the shaft does not affect the seeder mechanism.y

The gear-wheel C transmits motion to the operating mechanism of the seeder by means of a beveled gear d, which is xed on a shaft d', stepped into vertical bearing 116 of the bracket b3 and projecting upwardly through the base G of the seeder. This shaft d supports the distributing 'fan or wheel D and the stirrer or force-feed d2, located within the hopper.

The seed wheel or distributer D is cast with a hub and has a bevel-wheel d. Surrounding the hub is a central platform d3, which revolves immediately beneath the feed-ports of the seederA Extending outwardly from this platform are the tangential wings d4, each Wing being provided with a division-plate d5 on. its rear edge. The division-plates do not extend to the center of the wheel, but are cut away or terminate at the outer part of the center platform. It is apparent that anysuitable forin of distributers may be used in connection with the other parts.

The base G of the seeder, which forms the support for the hopper, is preferably in skeleton form and is supported upon the end-gate by two angular brackets g, which are secured by bolts. Near the center of the base it provides a bearing g for the shaft d', and upon either side of this bearing, but a little to the rear thereof, are the tubular feed spouts or ports g2. At this point the base is provided with a suitable transverse guideway or run g3, in which a cut-off g4 is mounted for sliding movement, as shown in Figs. 3 and 10. This IOO IIO

IIS

Greece cut-olf is provided with feed-openings g5, which are adapted to register with the feedports g2 when the cut-oft is drawn outwardly. The cut-off projects laterally beyond the edge of the base and is provided with an opening gf), through which the handle f3 of the clutchoperating lever F passes, the relation of the parts being such that the feed-openings g5 of the cnt-off register with the feed-ports of the base when ,the handle is thrown away from the device and into position to throw the clutch into engagement. The feed-passages are thereby opened when the clutch is thrust to revolve the distributer and are closed when the distributer is disconnected from the drivingshaft. This arrangement for automatic* ally operating the cut-off to open or close the feed-passages, according as the clutch is in or out of gear, is of a special advantage, as it prevents all wasteof seed. The moment the seeder is out of gear the feed of material is automatically checked.

The base-plate 7i 'of the hopper is secured to the base G, preferably by the same bolts that secure this base to its brackets g. The base-plate is provided with an opening registering with the bearing g in the base and with feed-openings h', registering with the feed-ports in the base. The base-plate is substantially circular in form, but is provided at its front edge with two segmental portions, each of which is provided with a slot h2 and a dial 71,3.

Feed-regulatin g valves g7 are pivoted at 7a4 to the upper face ot the base-plate and are arranged to work between the cut-off and the base-plate. As shown in Fig. 7, these valves are in the form of substantially triangular plates, and each is provided with a circular feed-opening h5 in its apex and with a guidepointer h6, running in one of the slots h2, which is struck on the circumference of a circle having its pivot h4 as a center. These valves move independently toward and away from each other and as they are brought toward the center of the base or hopper reduce the size of the feed-openings. The valves are set to regulate the size of the openings by the set-screws g8 according to the character of the seed to be cast, the several positions at .which they are to be set for this purpose being indicated by the dials. When adjusted for smaller seeds, to reduce the size of the openings the arrangement is such, by reason of the inward movement of the valves toward each other, that the area of the openings is brought toward the center of the fan or distributer, therebyinsuring an even cast. This is a matter of importance, as it is found in practical use that the adjustment produces an even and uniform cast of all sizes of seeds.

The hopper H is attached to the base-plate bymeans that admit of its ready removal when the seederis not in use. The baseplate is provided with overhanging lugs hw, which bear upon the flange of the hopper to hold it in place. The hopper is centered upon the base-plate by adjusting the ears or shoulders 71,8 of its flange beneath the overhanging lugs, this positioning of parts bringing the bolt hu in place to pass through the opening k12 in the base-plate, whereby the hopper is securely attached. By using these lugs and shoulders thehopper may be secured in place by the use of but a single bolt, thereby greatly facilitating its application to and removal from the base-plate. Within the hopper the stirrer or force-feed wheel cl2 is attached to the shaft d and rotates with it. This stirrer is in the form of a wing or vane and is set at a slight angle to the shaft, so that the seed is carried down into the openings by the inclination of its face, it being understood, of course, that the wing inclines toward the base-plate at its rear. A latchf4 is pivoted in the bracket on the side of the base in proximity to the handle f3 and may be thrown down upon either side of the handle to lock same in its two positions.. Thus when the handle is thrust outwardly from the base to open the ports and throw the clutch to operate the distribnter the latch may be dropped behind it to hold the parts in operative position, as in Figs. 3 and et, or when the handle is thrust inwardly to close the ports and disconnect the clutch thelatch may be dropped in front of it to hold the parts in inoperative position, as in Figs. S and 9.

It will be observed that the clutch E is cast in a single piece and is capable of movement lengthwise of the driving-shaft, thereby permitting the clutch to be operated to throw the machine into and out of gear without in any way disturbing thedriving-shaft. This provides for the maintenance of the aline ment of the sprockets A and b, whereby the wear and stretching of the chain b and its frequent running o of the sprockets, which occurs when the small sprocket is shifted by the throwing in and out of the gear, are avoided. The capacity of the machine to always keep the sprockets in line is of very great advantage.

The coil-spring c3 is loosely mounted on the drive-shaft and is not permanently fastened to any part of the machine, being engaged by the lug c2 and the ange e2 only when the machine is in gear. By this arrangement the spring when released from engagement with these parts by the disconnection ofthe clutch has nothing to carry back with it in resuming its normal position.

Seeders constructed in accordance with our invention are simple in construction, being composed of comparatively few parts, and are adapted to make uniform and even casts of all kinds of seeds.

Various modifications may be made without in any manner departing from the spirit of our invention. For example, the special form of clutch mechanism may be varied within the limits of such devices as will permit the connection and disconnection of the IOO IIO

shaft and gear-wheel without altering the alinement of the sprockets. Other suitable forms of distributers or of dampers or of vvalves may be used. Other arrangements for the automatic operation of the damper when the clutch is operated may also be employed, and in general such changes may be made as will suggest themselves to any one skilled in the art to which this invention appertains.
