GRAIN-SHOCK SCOOP.

Application filed August 30,

T 0 all whom it may concern Be it known that I, FREDERICK GEssNER, a citizen of the United States, residing at Deep, in the county of Bottineau and State of North Dakota, have invented certain new and useful Improvements in Grain-Shock Scoops, of which the following is a specification, reference being had to the accompany-, ing drawings.

This invention relates to new and useful improvements in grain scooping devices and more particularly to a grain shock scoop and the primary object of the invention is to proscoop shocks from the ground and convey the same to a member from which the same are dumped to a predetermined point.

A further object of the invention resides in providing a device which is simple and durable in construction, inexpensive tomanufacture and one which will be very efiicient and useful in operation.

lVith these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a side elevation of the device. Fig. 2 is a plan view thereof. Fig. 3 is a vertical longitudinal section through the samea Fig. 4 is a transverse section therethrough as seen on line ei4, Fig. 1. Fig. 5 is a similar view as seen on line 5-5, Fig. 2. Fig. 6 is a detail plan view of the rear structure with the dumping member removed. Fig. 7 is a detail side elevation partly in section. Fig. 8 is a detail section through the forward end of the dumping member showing in detail the operating means for the hinge section of the floor thereof; and Fig. 9 is a detail side elevation partly in section showing a portion of the means for actuating the endless elevator in connection with the forward end of the device.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a main frame, upon the rear end of which is suitably mounted the drive wheels 2 and upon the forward end of which Specification of Letters Patent.

are suitably mounted the steering wheels 3. arranged in connection with each of the rear wheels 2, is a sprocket 4:, over which extends an endless chain 5, said chain also extending over a similar sprocket 6 carried on a rotating shaft 7, which is mounted transversely of the frame 1. This shaft 7 also has a sprocket 8 thereon, over which extends a chain 9, said latter chain extending over a sprocket 10, carried on a drive shaft of an engine 11, the latter being suitably mounted on the frame 1. From this construction, it will be seen that as the engine is operated, the rear wheels 2 will be caused to rotate and drive to propel the device forwardly. A clutch mechanism, however, is arranged in connection with this shaft which will permit the engine to be operated or the device to be propelled, without affecting one another.

Suitably mounted to oscillate on the rear end of the frame 1, is substantially a wagon body or what may be termed a receiving and dumping member 12. on the rear end of the member 12, is an end gate 13, of improved construction which, in the normal position of said member 12, is in its closed position and held locked by keepers 1 1, which receive therethrough the free ends of rods 15 on the end gate. At one end of said end gate is an arm 16, which admits of the raising of the end gate by hand, while at the opposite end of said end gate, is a tongue or lug 17 which has a rod 18 pivotally connected therewith. The lower end of this rod 18 is engaged with a shoe or contacting member 19 carried on the rear end of the member 12. From this construction, it will be seen that as said member 12 is tilted, so that the rear end is disposed downwardly, the shoe 19 will contact with the surface of the ground to raise the arm 18 and correspondingly raise the end gate 18. Thus, it will be seen that as the member 12 is tilted, the end gate thereof will be automatically raised so that the contents of said member may be dumped therefrom.

I have provided a means for automatically raising the dumping member 12 and to this end, a shaft 20 is provided to extend transversely of the frame 1, forward of the engine 11. This shaft has connection with the drive shaft by means of a chain 21,

-which extends over a sprocket on said en- Hingedly mounted gine and last mentioned shafts and a pinion 22 on said shaft 20 meshes with a rack 23 which is carried on the forward end of the dumping member 12 to depend from the latter. A clutch mechanism 24 is arranged in connection with the shaft 20 and the pinion 22, so that at a predetermined time, said dumping member may be tilted with the operation of the engine.

The flooring of the dumping member 1, at the forward end thereof, has a hinged section 25 formed therein, which forms a substantial gate or door therefor. In the normal position of said member 12, this hinged section alines with the remaining portion of the flooring and I have provided a means for raising this hinged section as the member 12 is tilted or dumped. To this end, an additional pinion 27 is carried on the shaft 20, which meshes with a ratchet 28 carried on and depending from said hinged section 25. A clutch member is also arranged in connection with the shaft 20 and pinion 27, so as to dispose said pinion into operative position when desired and when so positioned and the engine is operated, said hinged section 25 will be raised to form a gate member for the device. This operation occurs upon the emptying of a load of shock or grain into said member 12.

Mounted on the frame 1, forward of the dumping member 12, is a rectangular frame 29 having a flooring 30 extending for a portion of the length thereof and hingedly projecting from the flooring which is arranged on an inclined plane and arranged in series, are the tines or elongated teeth 31. The free ends of these teeth are disposed to points immediately above the surface of the ground and are adapted to scoop up grain and shock as the device is propelled. Operatively arranged on each side of the frame 29, is an endless chain belt 32 which operates over sprockets 33 carried on the shafts 34 and connecting these chain belts at certain points in the length thereof, are the cross members or slats 35. One of the shafts 34 connects with a shaft 36 arranged on the frame 29, through the medium of a chain belt 37 and when this shaft 36 is rotated, the chain belts 32 which, together with the cross pieces or slats 35 thereon form a carrier, are operated. This shaft 36 is connected with the drive shaft of the engine by means of a chain 38 passing over sprockets on said shafts, so that the operating parts of the device receive their source of power from the engine and a clutch mechanism is arranged in connection with the sprocket on the shaft 36 so as to throw the operating parts into and out of operative position, when desired.

The front wheels 3 are mounted on substantially an arch member 40 and the side arms-of this arch are loosely guided through bearings 41 on the side bars of the frame 29. Pivotally connected to the forward portion of the frame 29, at the sides there of, are the arms 42 and 43, the former be ing designed in the form of a bell crank lever and the free ends of said arms are connected to coil springs 44, the latter be ing suspended from the upper portions of said arch member 40. These arms 42 and 43 are connected together by means of a transverse shaft and the arm 42 which is substantially a bell crank lever has one end thereof connected to an operating rod 46. The operating rod has pivotal connection with a lever 47 which is fulcrumed on the rear of the frame 29. Through the operation of this lever 47, it is obvious that the forward portion of the device may be raised and lowered, as desired, and a ratchet and detent arranged in connection with the le ver 47 permits the same to be retained in any adjusted position.

The member which has been described as substantially an arch member 40, has the crown thereof pivotally engaged with the arms of the same to permit pivotal engagement of the arms with respect to said crown. A suitable steering mechanism, such as is used in connection with motor vehicles and the like, is provided and arranged in connection with the arms of this arch member, whereby to steer the machine as the same is propelled.

I have provided a means for cooperation with the endless elevator 32, whereby to permit the latter to run only at predeter' mined times, such times being when a bundle or bundles are deposited on the teeth of the tines 31. To this end, a shaft 48 is mounted transversely of the frame 29, to oscillate thereon below the upper reach of the carrier 32, and the ends of said shaft are provided with crank arms 49 and 50. Connected with the crank arm 49, is a rod 51, which extends rearwardly and downwardly along one side of the frame 29 and has pivotal connection with a bell crank lever 52, the latter being pivotally mounted on a bracket or the like at the rear end of the frame 29. This bell crank lever in turn, has connection with a clutch mechanism 53 arranged in connection with the sprocket 36. Carried on the shaft 48 are a plurality of rods or arms 54 which, in the normal position of the shaft 48, depend from the latter to project over the tines or teeth 31. Thus as a bundle is deposited on the teeth of the tines 31, and the vehicle is traveling forwardly, said bundle or bundles will contact with the arms or rods 54 to force the same rearwardly and up wardly and by so operating said rods or arms, it is obvious that the clutch mechanism 53 will be turned to its effective position. As the clutch is effectively disposed, the sprocket 36.will be caused to rotate and correspondingly operate the carrier 32. I have provided a means, however, for the retention of the arms 54 in their raised or effective positions, after the bundles have been drawn therebeyond, or through the rearward portion of the frame 29. To this end, an additional rearwardly and downwardly extending rod or shaft 55 is provided, the same having pivotal connection at its forward end to the aforesaid crank arm 50 on the one end of the shaft 48. The rear-most end of this last mentioned rod or shaft 05 rests on a guide or keeper 56 mounted on the side of the frame 29, adjacent the rear end of the latter, as clearly shown in Fig. 9 of the drawings. Mounted for oscillation in the side of the frame 29, immediately below the guide member 56, is a shaft 57, one end of which is bent angularly as shown at 58, to form an extension thereon, the same depending to a point between the endless chains of the elevator 32 and immediately adjacent and below the lower rear sprocket 33, as clearly shown in Fig. 3 of,

the drawings. The opposite end of the shaft 57 projects outside of the side bars of the frame 29, and is designed to form a rightangular extension 59.

The extension 58 is weighted heavier than the extension 59, so as to normally force the extension 59 upwardly and said extension 58, when in its normal position, is disposed in the path of the transverse bars 35 of the carrier 32. As stated, the extension 58 is weighted heavier than the extension 59, so as to dispose the latter upwardly by a rocking of the shaft 57 in its bearings and an opening 60 is provided in the bottom of the guide member 56 to receive the one angular arm of the extension 59 therethrough as clearly shown in Fig. 9 of the drawings. In the normal position of the device, the rod 55 is adapted to rest upon the upper end of the upstanding angular arm of the extension 59, in a position as shown in dotted lines in Fig. 9 of the drawings. WVhen the shaft 48 is rocked by the swinging rearwardly of the depending rods 54, the rod 55 will be drawn forwardly and dropped into a position as shown in full lines in Fig. 9 and thus raised behind the upstanding angular arm of the extension 59. The rod 55, with all parts connected thereby will be held in this position until such time as a bar 35 of the carrier 32 strikes the extension 58 and upon striking the latter, the shaft 57 will be rocked to swing the extension 59 downwardly, whereby to permit the rod 55 to slide to its initial position and permit the shaft 48, with the bars or rods 54 thereon to also return to their initial positions.

In practice, it will be seen that as the device is propelled, the tines or elongated teeth 31 will receive thereon loads of shock and grain met in the path of the device. As a bundle is received on the tines or teeth 31, and-the device is propelled, said bundles will contact with the depending arms orrods 54 to force the latter rearwardly and upwardly and with such operation of the rods, said shaft 48 will be rocked to correspondingly draw forwardly on the rods 51 and 55. The rod 51 will, obviously, throw the clutch mechanism 53 into its effective position and cause the elevator 32 to be operated. The drawing forwardly of the rod 55 will dispose the same to a position as shown in full lines in Fig. 9 and thus hold the bars 54 in their raised positions and also retain the clutch mechanism in its effective position. The shock and grain will be conveyed upon an inclined bottom of the frame 29 and passed to the dumping member 12. After a load of shock has been emptied into the member 12, the transverse bar 35 of the carrier 32 will contact with the extension 58 which projects in the path thereof and cause the shaft 57 to be rocked in its bearings. With such rocking of the shaft 57, the extension 59 thereof will be disposed downwardly to permit the rod 55 to return to its initial position. With such a return of the rod 55, the shaft 48 will be again rocked to permit the rods 54 to return to their depending positions and the rod 51 will, of course, also be operated to return the clutch to its ineffective position. The carrier 32 will, therefore, be inoperative at such time. After such occurrence, the weighted end 58 of the shaft 57 will return to its initial position and cause the extension 59 to be forced upwardly so that the one arm thereof may be disposed through the opening in the guide 56 and hold the rod 55 in a position as shown in dotted lines in Fig. 9 of the drawings. The device is then ready for another operation, such as above described.

When a sufficient amount of grain or shock has been emptied into the member 12, the hinged section 21 may be caused to swing upwardly through the operation of clutch member on the shaft 26, and at a predetermined time and place, the member 12 may be tilted so that the shock and grain therein are directed downwardly toward the rear end of the same. As the dumping member 12 is tilted, the end gate 13 will be automatically raised to permit the contents of the dumping member to be discharged therefrom.

From the foregoing it will be seen that I have provided a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation and while I have particularly described; the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention, what is claimed is 1-- 1. A device of the character described comprising a wheeled frame, a scooping device arranged at one end of the frame, conveying means leading from the scooping device, and means under control of the material collected by the scooping device for controlling the operation of the conveying means.
