The objects of my present invention are to facilitate the loading of the bod of a manu-re spreader, livering the loadvv in a plane nearer the ground, to simplify and strengthen the construction of the spreader, and to provide an irnproved driving mechanism for the beatsr.

Y arrangement of parts to similar as hereinafter descr being pointed .out i the annered claims,

The manure spreader to which my invention relates, like those now in common use,`

comprises a body for holding the load. 'of manure, a rotating toothed' beater at the rear end of the body for distributing the loadya movable bottom for vmoving the load' rearwardly toward the beater as the opera-v tion of spreading continues,

and means capable of being controlled by the driver at the to provide means or deseat for operating the movable parts. My improved beater, however, differs in many essential particulars from those hitherto in use, as will appear from the following description of the accompanyin drawings, in which 1 denotes the body o the spreader supported at the forward end upon wheels 2, 2, and at the rear end upon'wheels 3, 3. The forward end lof the body is provided with a reach 4 which extends from the top of the body forward over the'axle of the Wheels 2, 2, space being'thus provided -in turning' corners for the wheels 2, 2, to pass under the reach 4, and.' also allowing the bottom-of the body to be supported in a plane lower than the axle of the wheels 2, 2. The rear end ofthe body is suspended from the rear axle 5 by means of brackets, one of which is shown at 6, Fig. 3, thereby bringing the bottoni of the body in a plane below the rear axle upon which the wheels 3, 3, are carried. By this means of supporting the forward and rear ends of the body its bottoni isq brought comparatively close to the ground, so that the manure in loading requires but a slight elevation. In order to securely support the body of the spreader at its forward end by the forward axle, and with its rear end suspended from the rear axle, -I mount the body upon two steel sills 7, 7, consisting of channel bars running lengthwise the body beneath its sides, at the rear ends of which the brackets 6 are riveted. The forward ends of the sills 7 are bent npwardly and inwardly, as shown at 8, 8, Figs. 6 and 7, and are attached to their forward ends to the reach 4. The steel channel bars forming the sills of the body are united at their forward ends by a cross bar 9, bolted at its ends to brackets 10, 10, which are securedto the sills. The middle and rear ends of the sills are attached by joint bolts 11 to woden spacing bars'12, 12. Bearings at# tached to the sills 7 are provided for the front and rear sprocket wheels 13 and 14 around which'the movable bottom 15 passes.

The movable bottom is constructed in the usual manner by transverse strips attached at their ends to chain links 16 which engage shaft 19 having at its` thesprocket wheels 13 and 14, and, in their passage between the tops of the sprocket wheels, rest upon a series of supporting rolls 17, each of which is j ournaledupon a bracket 18 riveted to the inner sides of the sill 7. The sprocket wheels 13 are carriedupon a ends polygonal tips 2 0, 20, adapted to receive a wrench by which the shaft 19 may movable bottomnnoved backward or forward. v

The sprocket wheels 14, 14, are attached to a shaft 21 which carries upon one end a worm gear 22 engaged by a worm 23, havlng a geared connection, not shown, with a sprocket wheel 24, which is driven by a chain 25 from a sprocket wheel 26 carried upon and attached to the rear axle 5. The

driving mechanism for the bottom, whichy comprises the worm gear 22 and worm 23 is of the usual form of construction now used 1n manure spreaders, and is substantially like that shown in United States Patent N o.

268,410, dated December 5, 1882, and vforms no part of my present invention.

The beater, which. consists of the revolv- 1ng cyl1nder 27 provided with radial teeth 28, 1s mounted concentrically upon the rear axle 5 and is attached by screws 29 to a sleeve 30, which is capable of turning loosely upon the rear axle 5, and carries upon its opposite end a pinion 31 which engages pinlons 32 turning loosely upon studs 33, which are held in a rotatable plate 34, having a hub 35 which is journaled in one of the brackets 6 concentrically with the sleeve30. The pinions 32 engage an internal gear 36 which is attached by a spline to the rear axle 5. Turning loosely upon the ends of the rear axle 5 are the supporting wheels 3, 3, each carrying a pawl 3l which engages a4 ratchet wheel 3b attached to the ends of the rear axle 5, so that during the forward movement of the manure spreader the rotation of the'supporting wheels 3 is imparted to the rear axle 5,*and the rotation of the rear axle 5 rotates the sprocket wheel 26 and the internal gear 36` The plate 34, as the internal gear 36 rotates, is free to rotate with the internal gear, so that a rotary motion of the internal gear36 is not imparted to the beater through the pinion 31. The

y plate 34 is, however, provided with a series of external teeth 37 by which the rotation of the plate 34 may be checked by means of a swinging pawl 38 pivoted at 39 to one of the body sills, and connected by a link 40 with one arm of a rocking three arm'ed lever '41 on a rocking shaft 48, which is connected by a link 42, bellcrank 43, link 44, bell crank 45, and link 46 to a hand lever 47 near the drivel-s seat, which enables the operator at will to swing the upper end of the pawl 38 yinto the path of the revolving teeth 37,

thereby checking the rotation of the plate 34 be turned by hand and the and holding the .pinions 32 stationary, so y that rotary motion will be imparted to the pinion 31 by the rotation of the internal gear 36 and thereby revolving the beater.`

The third arm 49 of the three armed lever 41 is connected by a link 50vwith a bell crank 51 journaled upon the top of one of the sides of the body, and connected with one end of a tailboard 52, Fig. 1, by which the load of manure is held from working back and impeding the starting of the beater as the spreader is driven to the eld.` Upon the opposite end of the rocking shaft 48 is attached a two armed lever as shown in Fig. 3, one of the arms 53 being connected by a link 54 with a bell crank 55, similar tothe bell crank 51,A journaled uponl the upper edge of one of the sides of the Vbody and connected with the opposite end of the tailboard 52. The other arm 56 of the two armed lever carried upon the rocking shaft 48 is connected by a link 57 with operative mechanism for throwing the worm 23 into and out of engagement with the worm gear 22, in a` similar manner to that described in United States Patent No. 268,410, dated December' 5, 1882.

The rocking of the shaft 48 in one direction, by means of a lever handle 47 serves to raise t-he tailboard, to connect the movable bottom with the driving power by means of the worm 23, and to put the beater in operation by swinging the pawl 38 into the path of the teeth 37, and the reverse movement of the lever handle 47 will lower the tailboard, disconnect the movable bottom and check the operation of the`beater.'

As the axis about which the wheels 3, 3, revolve is placed at the extreme rear end-of the body coincident with the axis of the beater, the wheels 3 are caused to cover but a small. portion of the sides of the body, leaving the entire sides between the extreme forward end of the body and the line 58 exposed, and thereby removing from the greater portion of the body the impediment to loading presented by the large supporting wheels 3, 3.

The rockin shaft 48 is journaled in the framework o the body to the rear of the line 58, and the link connections between the rocking shaft 48 and thel lever handle 47 which traverse the length of the body, are located in a plane below the sides of the body, thereby enabling all that portion of the sides in front of the line 58 to be either attached to stakes held in stake irons or, as in the present instance, to be hinged to the sills at 59, so that the sides 60, 61, may be removed. from their upright position to obviate the necessity of loading the body over the top of the sides. In the present instance I provide the sides 60, 61, with stake 1r ons 62 to receive stakes attached to an extension, shown at 63, Fig. 1, where one, of these eX 4resented in Fig. 1,' the pended from a chain 6 stretched across the upright stakes 68, 68, supported at their lower ends by the framewor plying a cran of the body.

In the' operation of loading, the `manure may be deposited upon the movable bottom through the open side of the Abody and oppo-l site the sides 60, 61. The load may then be moved back a ainst the tailboard 52 by apto the polygonal tips 20 of the sprocket-shaft 19, and the lgading continued at the vacant space at the forward .end of the body.

Yby the attendant by a lever han Means for changing the speed of the movable bottomodurin the operation of spreading is provided su stantially like that shown inUnited States Patent No. 268,410 of December 5, 1882, said means bein operated e 69V and `intermediate connections which however form no part of my present invention. The tailboard 52 is attached to the hori- `zontal arms 70 of the bell cranks 51 and 55,

and is raised and lowered by swinging the bell cranks as already described, by means of the intermediate connections between the bell cranks and the lever handle 47 located near the drivers seat.

The construction and operation of the tailboard is substantially like that of the tailboard described inv United States Patent issued to me May 29, 1906, No. 821,779, said patented tailboard comprising a hinged sectionl corresponding to the transverse' bar 71 in the present tailboard, which is hinged to the tailboard 52 and pivotally connected by bent arms 72 with the sides of the body at 78. Depending from the bar 71 are a series of teeth 74 which, when the tailboard is raised into the position shown in Fig. 9, are caused to stand at an oblique angle and contiguous to the revolving beater, for vthe purpose of pulverizing any large lumps of'ma'nurethat may be thrown by the beater against the teeth 74. When the tailboard is in its lowest position, as shown in Fig. 1, the teeth 74 are supported by the bar 71 so as to clear the movable bottom 15, and the teeth 74 are then brought into substantially the plane of the tailboard 52. As the tailboard 1s raised, however, by the rocking of the bell cranks 51 and 55 into the position shown in Eig. 9,` the hin ed bar 71, and teeth 74 are swung upon t e tailmeans. of their -pivotal connecbody of the spreader through board 52 by tion with the yenable it to teeth of the the bent arms 72 in order to bring the teeth 74 at the proper angle, and in proper relation to the beater to serve as a pulverizer.

By my improved construction I lower the center of gravity of the load, render the body easy to be loaded by hand, enable vpowerto be employed in loading as represented in Fig. 1, and provide means for depositing the load upon any portion of the movable bottom most convenient, and moving the same backward against the beater.

I also provide means for driving the beater l without the use of a sprocket chain and am enabled to entirely inclose the beater driving mechanism. The distribution of manure is accomplished upon a lower plane than in the ordinary type of manure spreaders now in use, and I so construct the tailboard as to do double duty of protecting the beater and also pulverizing the manure when the latter is in operation. Thisl tailboard, however, when elevated, leaves a passageway for the material at the rear end of the body structure which is normally unobstrugted except for the beater or cylinder device itself, the latter when at rest consti tuting the on'ly means to prevent the escape of the material backward, shredding oil' the material at the rear end of the slowly moving mass, lifting it up in front of the axis of the ground wheels and throwing it over the. top of the beater and backward to the ground.

Another important advantage incident to this mechanism arisesfrom this: that it is formed in two parts, namely, a body structure, and a rear-wheel-and-beater structure which, although united together, pendent of each other as concerns their mounting upon the rear wheels. The beater pr distributer, astwell known, is subjected to very severe stresses and strains,I in its work of tearing to pieces the ,tanglety and matted load and throwing it backwar and in my case this severe work is taken directly7 upon the ground and when at work, t

are inde- 11o i wheels as an abutment, this being in contradistilnction from the heretofore able bottom, antaxle journaled at the rear of the body and above the plane of the bottom, supporting whe'elsl carried by saidA axle, with the sides of the body in front of the periphery of said wheels removable, and means for Vmoving said'bottom to carry the load rearwardly duringthe process of loading.
