MANUBE-SPREADER.

spcification of Letters Patent.

Application led. March 23, 1907. Serial No. 364,051.

To all whom it may concern:

Be it known that we, DALroN K. WILSON and EUGENE BUswELL, citizens of the United States of America, and residents of Waterloo,'Blackhawk county, Iowa, have in-i vented certain new and useful Im rovements in Manure-Spreaders, of whic the following is a specification.

Our invention relates to improvements in manure spreaders, and the objects of our im rovements are, first, to provide anew and efficient device for var Ying the speed of the apron relative to the 'af vance of the machine, second, to furnish improved bolsterbrackets for supporting the detachable box on the running-gear of any ordinary wa on, andthird to otherwise sim lify and ac apt the mechanism and render lts arts adjustable as will be hereinafter fuly indicated. These objects we have accomplished b the meansv which are hereinafter describe and claimed, and which are illustrated in the drawings hereto annexed, in which,

Figure 1 is a plan view of our improved manure-spreader, provided with an endless apron, Fig. 2 is a right side elevation of the same, Fig. 3 is a detail view of the adjustable connection between one of the side-rods and its forward pivot-block, Fig. V4 is a detail view of-.one of the rear bracket-guides, and

, Fi 5 is a front elevation of one of the front bo ster-connections with its brackets and guides. Fie. 6 is a left hand side elevation of said mac ine. Fig. 7 is a vertical longitudinal section of the right hand end of the beater shaft. Fig. 8 is a rear elevation of one of the .rear chain guides. Fig. 9 is an enlarged detail side elevationl of one of the front chain guides. Fig. 10 is an enlarged detail view of the intermediate mechanism between and connected to the beater-drum shaft and the apron-shaft, indicating' the positions of its moving, parts when set for discontinuing the movement of the apron independently of the rotation of said beaterdrum shaft. V

Similar reference numerals refer to similar parts throughout the several views.

Our improved manure s reader mechanism is arranged and suitab y adapted to be placed upon and adjusted to the runninggear of any ordinary four-wheeled wagon.

lt consists of a body formed principally of the bottom 24 having sides 30, the latter capped with rails 31. A shaftm 8 is placed transversely to.the rear end of the box thus formed, the rear end of such box being Open,

so that its contents may be carried to an imi pact with the beater-wheel 26, when the endess apron, com osed of endless chains 25 carrying upwar y flanged slats 40,V is moving to the rear. i

The spreader has two hand-o erated levers, 4 and 46, for use as follows. he lever 4 has its lower end pivoted on a stud 35 on the outside of the side 30 on the right, and works back and forward within a rack-bar 36, and engages one or the other of its notches as desired to control the speed of the apron. Pivotally co'nnected'to the lever 4 on a stud 3 is a sleeve 1, whose rear end is irovided with an inteiorly threaded bore w erein is adj ustably received the threaded front end of the side or connecting rod 2. This adjustment is furnished for the purpose of taking up any slacknss` or lost motion accruing through wear on the regulating )arts of the speed-controlling mechanism. of the rod 2 is bent inwardly and iivoted in an opening in the member 5 .of the bell-crank lever 5 6. Said bell-crank lever is fulcrumedon a'stud 39 on an upright which is supported about the shaft 8, and the member he rear endl 6 is slotted as shown to receive the inturned front end of the lever 7. The rear end of the lever 7 is connected to an eccentric strap movable over an eccentric 55 fixed on the* end is pivoted to a short stub shaft 11 on i which is also centrally pivoted a double crank 9, the parts 9 and 10 being integrally connected. In the rear end of the crank 9 is pivoted the upper end of a link 12 and in the front end of 9 is pivoted the upper end of a link 16, thel lower end of each link being pivoted in a lug on each pawl 13, the latter being ivotally secured to the forward ends of the evers 15, whose rear ends are fulcrunied on the end of the shaft 47.

The shaft 47 carries the sprocket-wheels 33 which engage the sprocket-chains 25 at the rear, the ront ends of said chains being-carried over idler sprocket-wheels 34 at the lfront. The ends of the shafts on' which the wheels 34 are pivotally mounted, are secured screw 51.

. tension spring? ratchet-wheel 14 which is secured to the shaft 47 carrying the apron-sprocket wheel 33 has its teeth engaged by the pawls 13. The rear end of a connecting rod 37 is pivoted on the stub shaft 11, the front end of said rod being seated in a sleeve 42, the latter having a transverse perforation or bearing for a short shaft 29, said shaft being adjustably secured to said sleeve by means of a set- The outer end of the shaft 20 carries a rotatably mounted sprocket-wheel 28, a sprocket-chain 27 connecting the wheels 28 and 52 on each side of the spreader, as shown in Fig. \1 On each end a sleeve 53 is secured to the-shaft 8 by means of a set-screw 63, the outer' ends of said sleeves having teeth to engave similar teeth on the inner ends of the hu s of the transversely slidable sprocketwheels 52. The extreme ends of the shaft 8 have lterminal caps 61 having set-screws 62 between which and the wheels 53 are placed 41, which serve to retain said wheels with t e teeth of their hubs in normal engagement with the teeth of the sleeves 53. 1f it is desired to so place the sprocket-chains 27 that they will contact with the driving sprockets xed to the inner faces of the driving-wheels of a running gear of a certain amount of separation apart, the adjustment is made by sliding the shafts 29 in their bearings and the sleeves 53 on the shaft 8 a pro er distance, and then securing them with thelr respective set-screws.

The lever 46 adapted to engage a dentated rack-bar 5 4 on the left side of the spreader has its lower end ivoted on a stud 60 to the left outer side of the box, and to it is pivoted the front inturned end of a connecting-rod 45, whose rear end is' turned outwardly and pivoted in a crank 38 secured to a shaft 43 transverse of and under the bottom 24. Secured to the right end of the shaft 43 is a like crank 38, and each crank 38 carries a perforated lug 44 which incloses the levers 37. When it is desired to rotate the beater-wheel 26, the lever 46 is thrown forward to the front notch in the rack-bar 54, and the crank 38 thus lowered with the lug 44, the connecting rod 37, and the shaft 29, which lowers the sprocket-chain 27 on each side u on the driving sprocket-wheels 57 attache to the wagon drive-wheels, the shaft 43 as it turns, lowering the right-side crank 38 and through its medium the right side s rocket-chain 27. To stop the rotation of said eater-wheel, the lever 46 is thrown to the rearward notch in rack-bar 54, which reverses the above described movements of said parts and elevates the s rocket-chains 27 from off the driving sproc et-wheels.

- Our improved spreader is adapted to be fitted to wagon running-gear of different dimensions mounted on carrying wheels 58 and59, and has for an intermediate support for its front end a cross-beam 22, the latter, which is shown in perspective in Fig. 5, being arranged so as to be set upon the forward bolster of such running-gear. The beam 22 carries at each end a bracket support 21 having a top plate 20. The front end of the box of the spreader rests upon the plates 20. ln the proper positions, guides 23 are attached to the top of the cross-beam 22, and have depending ends, and are adapted to be used as supports for the apron 64, the ends of the slats of said apron being slidable over said guides.

Fastened to the bottom of the rear part of the spreader box 24 on each side are hangers 17, provided with recesses 19 to receive and engage the top part of the rear bolster of the running gear. Each hanger 17 has a guide 18 attached to its inner side, as shown in Fig. 4, as a guide for the chains 25 in the rear. The shaft 8 is rotated when the lever 46 is thrown forwardly to lower the chain 27 into engagement with the driving sprocket-wheel 57. When the shaft 8 is rotated the eccentric 55 causes the pitman 7 to oscillate the lever 10 and through it the lever 9 which draws on the pawls 13 alternately, one pawl clicking back while the other rotates the ratchet-wheel 14. The rate of speed of the apron 25 is adjusted by throwing the lever 4 so as to move the forward end of the pitman 7 up or down to rock the lever 10 through a larger or a smaller angle, so that at each impulse the pawls 13 may rotate the ratchet-wheel 14 over the space of a larger, or smaller, number of teeth. When the inturned end of the pitman 7 moves to the bottom of the slot in the lever 10 the throw of the pawls is at its maximum and several teeth are passed over onthe ratchet-wheel at each stroke. When the inturned end of said pitman is moved to the top of said slot the effect of each stroke is reduced to a minimum, in fact the stroke of the pawls is less in amplitude than the length of a tooth on the ratchet-wheel, and as indicated by the dotted lines in Fig. 10, the pawls do not move away from the teeth on which they rest but simply move thereover with a short stroke less than the length of the teeth, and do not become disengaged therefrom, which results in stopping the rotation of the ratchet-wheel and the movement of the apron. By this means the movement of the apron may be stopped independently of the rotation of the beater-drum, which is desirable at 'times of certain emergencies. The aplron may be started in motion again by s `fting the lever 4 a notch or more forward, to lengthen the throw of the pawls enough so that they ma disengage with thegteeth of the ratcheteel.

. upper member of said bell-crank lever, a

seams Having described our invention what we E claim es new, and desire to secure by Letters Patent, is

In e manure spreader, in combination, a box mounted on carrying-wheels, a movable apron in said box, a ratchet-Wheel adapted to move said apron, a beater-drum secured to a rotatable shaft et one end of said apron, en eccentric secured on one end of said shaft, a strap 0n said eccentric having a projecting pitman, a bell-crank lever Whose lower member is slotted pivoted to said box, e hand-lever pivoted to said box, a. connecting-rod between said hand-lever and the second bell-crank lever whose upper member is slotted pivoted to seid box and provided with oppositely directed lowe` arms, arms pivote( on the end of the ratchet-wheel shaft, ewls pivoted to seid arms and ede tedp to operatively engage the teeth of sai( ratchet-Wheel, connecting-rods between said pawls and the oppositely directed arms .of the second bell-crank lever, the outer end of the said pitman being adapted to enter and slidably engage the slots in both said bell-crank levers.
