Application filed March 28, 1914. Serial No. 828,010.

To all whom it may concern Be it known that we, Asa L. DUDLEY and Joan J. Scininrr, citizens ofthe United States, residing at Glenville, in the county This invention relates to an attachment for manure spreaders and similar machines and broadly stated, embodies certain improved mechanical features whereby such machines may be employed for the distribution or spreading of straw over the ground.

The invention has for its primary object to provide an attachment of the above character embodying a follower, and means for intermittently moving the follower to forcibly feed the straw to the cylinder of the spreader.

The invention has for another object to provide an attachment for manure spreaders which may be easily and quickly mounted in place upon the body of the spreader, said attachment including. a follower for forcibly feeding the straw to the spreader cylinder, mechanism for imparting a slow intermittent feeding travel to the follower and a comparatively rapid reverse or forward movement thereof, and means automatically actuated at the end of the forward and rear travel of the follower to render said mechanism inoperative.

The invention has for a furtherobject to.

produce an attachment which may heap- .plied to various forms of manure spreaders now n common use without necessitating material alterations therein, and which will satisfactorily and efficiently perform the functions for which the same is devised,-

without injury to the parts of the spreader mechanism or in any way impairing its con tinued usefulness.

Vith the above and other objects in view. .as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that we shall hereinafter fully describe and claim.

For a full understanding of the invention,

reference is to be had to the following descr1pt1on..and accompanying drawings, in which :Figure 1 is aside elevation showing our improved straw spreading attachment arranged upon a manure spreader; Fig. 2 is a longitudinal section thereof; Fig. 3 is a.

section taken on the line 3-3 of Fig. 1; Fig. 1 is an enlarged elevation illustrating the reverse arrangement of the drive gearing for the follower with respect to the arrangement shown in Fig. 1; Fig. 5 is a transverse section taken on the line 5-5 of Fig. 1; Fig. 6 is a section taken on the line 66 of Fig. 1. Fig. 7 is a detail section illustrating the trip device.

Referring in detail to the drawings, 5 designates the body of a manure spreader, which is mounted in any suitable man nerat its front and rear ends upon the supporting wheels 6 and 7 respectively.

8 designates the spreading or distributing roller which is mounted in the rearwardly and upwardly inclined arms 9 fixed to the body of the spreader and is driven through the medium of a chain 10 from the rear wheel axle.

Our improved straw spreading attachment includes a suitable hopper or rack for the straw consisting of side walls 11 which have lower inwardly inclined portions 12 secured to opposite edges of a bottom or floor 13. To the side walls 11 a vertically disposed series of strap bars 14 are secured which are adapted to be received in spaced sleeves or cuffs 15 secured to the side walls of the spreader body 5. To the rear ends of the side walls 11 of the straw receiving rack or hopper, longitudinally extending rearwardly projectin bars 16 are secured. The comparatively short longitudinal bars 17 are a so secured to the side walls 11 above the bars 16. Upon the inner sides of the walls 11, longitudinally extending rails or cleats 18 are provided for the support of a follower 19. This follower is longitudinally movable between the side walls of the hopper or straw rack to forcibly feed the straw to the distributing or spreading roller 8 in a manner which will be fully pointed out in the following description.

In suitable bearings mounted upon the upper edges of the rearwardly extending bars 16, the ends ofa beater shaft 20 am journaled. This shaft is provided with a plurality of longitudinally extending blades 21 which are adapted to engage upon the straw and beat or force the same downwardly upon the teeth of the rotating spreader cylinder 8. The rotating blades 21 are covered by means of the shield plate 21'. said plate preventing the material being thrown upwardly and rearwardly by the blades in their rotation. Upon one end. of the shaft. 20, a sprocket wheel 22 is loosely mounted and is connected by an endless drive chain :23 with a similar sprocket wheel 2-! carried by one of the rear supporting wheels 7. A clutch member 25 is l eyed upon the beater shaft 90 for engagement with clutch teeth prodded upon the sprocket wheel whereby said wheel may be locked to the beater shaft. This sliding clutch member is actuated through. the medium of a lever 26 fulcrumed upon the bar 17 and connected by the rod 27 to a lever which is mounted upon one of the side walls 11 of the straw rack or hopper at its forward end. This lever is provided with the usual spring pressed dog for engagement with the teeth of a rack segment 29. An additional smaller sprocket wheel 30 is also fixed upon the end of the beater shaft 20 and is connected by means of a sprocket chain 31 to a sprocket wheel 32 which is journaled upon a stul.v

shaft 33 fixed in a vertically movable plate 34-. One face of this sprocket wheel is provided with a gear 35 for engagement with'a gear wheel. 36 journaled upon the end of a stub shaft 37 which is suitably mounted upon one of the side walls 11. The plate '34 is provided with an elongated longitudinal slot 38 for the accommodation of this latter shaft. The upper and lower ends of this plate are also provided with slots 39 through which stud bolts 40, fixed in' the side wall 11 of the hoppcnpro iect. The gear wheel 36 meshes with the teeth of a pinion 41 which is secured to or integrally formed with a sprocket wheel 42, said sprocket wheel being journaled upon a stub shaft i3 secured .in the wall 11. This sprocket wheel is tra.v-- ersedby the chain 4 1 which extends around a similar sprocket wheel 45 fixed. upon one end ofa transverse shaft 4-6 journaled at its ends in supporting members 47 secured to the rearwa-rdly extending bars 16.

48 indicates a tensioning pinion for the chain which is engaged with one stretch thereof.

Upon the shaft 46 adjacent its opposite ends, sprocket pinions 49 are fixed. These pinions are connected by means of the end less chains 50 to similar sprocket pinions 51 which are rotatably mounted upon the bracket arms 52 secured to the rear ends of the longitudinal rails or cleats 18f The, follower 19 above referred to is preferably in the form of a plurality of parallel bars 53 extending transversely betweenithe side walls 11 and connected by a series of bars'54. The upper bar 53 at its ends is suitably secured to the upper stretches of the respective chains'50, so that the same is moved by said chains between the side walls 11. The front ends of these side walls are connected by means of a transverse rod To the rear edge of the vertically movable plate 3-], a rod 56 is rigidly secured, the

ends of said rod being horizontally disposed and the intermediate portion thereof extend ing in parallel relation to the plate 34. i lever 57 is pivctally mounted intermediate of its ends as at 58 upon the vertical portion of the rod 56. lever, one end of a dog or pawl 59 is fulcrunied, the other end thereof being disposed below the gear 36 and adapted for engagementwith the teeth thereof. This dog is adapted to move vertically in a guide loop 60 which is secured upon the rod 56. The upper end of the lever 57 is pivotally connected to a pitman 61, the other end of said pitman being eccentrically connected to the sprocket wheel 32.

6:. indicates a substantially U shaped bar, one arm of which is pivotally connected at its upper end as at 63 to the upper portion of the horizontal rod 56. The opposed arm of this U shaped lever is fulcrumed at its lower end as indicated at 64: upon the side wall 11 of the straw rack or hopper. The rear end of a longitudinally extending rod 65 is pivotally connected to the upper end of this latter arm of the lever 62 and is pivotally connected adjacent its forward end to a. lever 66. The lower end of this lever is fulcrumed as at 67 upon the side wall 11 of the hopper and carries a spring pressed friction block for engagementwith the upper edge of a curved bar 68. At the opposite ends of the rod 65, the same 1s provided with the .trip fingers 69, which project through slots 69 in the side wall 11 and are disposed in the path of movement of the upper bar of the follower 19. To the upper horizontal portion of the bar 56, one end of a chain 70 is attached. To the lower end of this chain, a. coil spring 71 is connected, said spring being secured to the pawl 59 intermediate. of its ends, and serving to normally hold said pawl against the gear wheel 36 in the movement of the lever 57. The spreader is of course provided at its rear end with the usual rake 7 2 through the tines of which the straw is drawn by the teeth upon the rotating cylinder 8.

In the lower end of this Having now fully described the co'nstrncsprocket wheel43 rot-ates the rear transverse shaft. 46, as indicated by the arrows'in Fig.

v1. In this manner, it will be seen that a step by step or intermittent longitudinal movement is imparted to the chains 50, the follower 19 of course being correspondingly moved from the front to the rear end of the rack or hopper containing the straw. The

straw is thus forcibly fed to the beater blades 21 and by said blades directed to the rotating toothed cylinder 8, said cylinder drawing the straw between the tines of the rake 72 and spreading the same upon the ground as will be readily understood. \Vhen the follower 19 reaches the end of its rearward movement, the upper bar 53 thereof will engage th t ip finger G9 on the rear end of the rod 65, and move said rod rearwardly to a sufiicient extent to lower the plate and dispose the pawl 59 out of engagement with the teeth of the gear 36, the lever. 66 being moved to a substantially central vertical position upon the curved bar 68. When it is desired to move the follower to the forward end of the straw hopper, the operator simply shifts the lever 66 rearwardly, thus forcing the plate 34. downwardly to a further extent and engaging the teeth of the gear 33 with the teeth of the gear 36. The gear 33 being ro tated by the chain 31, it will be obvious that the direction of rotation of the gear 36 is reversed, and a continuous movement from the rearto the front end of the rack or hopper imparted to the follower by means of the mechanism above described. When the follower again reaches the forward end of its travel, it engages the tripfingeronthe forward end of the rod 65 and shifts saidrod so as to return the lever 66 to its vertical position and render the operating mechanism inoperative- -When the lever 66' .15 again shifted forwardly, it will be understood that the intermittent rearward movement of the-follower is repeated to forcibly feed'the straw to the distributing mecha msm.

From the foregoing description taken in connection with the accompanying drawings, the construction, manner of operation and several advantages of our invention will be clearly and fully understood. As the de vice consists of but comparatively few parts,

it will be appreciated that the same is light in weight and may be readily lifted into positon upon the body of the spreader.

The adoption of our improved straw spreading mechanism will require no material alterations in the construction of the spreader or prevent its subsequent use for spreading of manure or fertilizer. By the comparatively rapid continuous forward movement of the follower after the straw has been completely discharged from the rack or hopper, it will be apparent that it is i only necessary for the machine to move forwardly a few feet. Thus but a comparatively restricted portion of the ground surface will be uncovered by straw, in the movement of the machine across a field. It will further be manifest that by means of our invention we have materially increased the utility of the ordinary manure spreaderso that the same will satisfactorily perform two important purposes.

Our improved straw feeding and distributing mechanism being comparatively simple in its construction, may be produced at small manufacturing cost and is also highly durable aswell as efiicient in practical op eration.

\Vhile we have shown and described the preferred construction and arrangement of the several elements, it is to be understood that the invention is susceptible of considerable modification therein and we therefore reserve the privilege of resorting to all such legitimate changes as may be fairly em; bodied within the spirit-and scope of the invention as claimed.
