To all whom [It may I'SOYZOCJJKFL:

Be it known that I, Luv; ll. lismmu, a citizen of the United States of June-rice, and a resident ()Tl Sandwich, in the county of Dekalb and State of Illinois, have invented cor-. tain new and useful Improvements in Manure-Spreaders, of which the following is a specification. 5

This invention relates to thatclass of manure-Spreaders in which the manure is carried rearward by a traveling apron and evenly and gradually distributed on the round by a rotating beater-cylinder arranged at the rear of the machine; and the resent invention e a simple, durable, and eflicient structural arrangement and combination of parts afi'ording a perfect control of the various operating mechanisms of the machine by the operator from the usual drivers seat and with which the'various operating mechanisms are controlled, sothat any one mechanism while in active operation locks an opposing operatin mechanism in a dormant condition until sue first-mentioned mechanism completes its movement and be comes automaticall dormant, or rendered dormant in a manua manner by the operator,

I all as will hereinafter more fully appear and be more articularly pointed out in the claims. In t e accompanying drawings, Figure 1 is a side elevation of a manure-spreader illustrating the general arrangement of the pres em; invention. Fig. 2 is a skeleton perspective view of the various operating mechanisms of the manure-spreader. Fig. 3 is a detail plan View illustratin the mechanisms 'for imparting motion to the traveling apron and the beater-cylinder. Fig. 4 is a fragmentary longitudinal sectional elevation of the front portion of the main body, illustrating a portion of the mechanism for stopping the forward movement of the traveling Fig. 5 is a detail transverse section illustrating the central support for the trav cling apron. Fig. 6 is a detail longitudinal section of the. rear portion of the manurespreader. Fig. 7 is a detail )lfl'll view of the beater-cvlinden Fig. Sis a detail rear elevation of the pressure-comb.

Similar numerals of reference indicate like parts in the several views.

As represented in the drawings, the present mallure-spreader in its general arrangcment comprises the usual box-shaped body 1, having a skeleton frame at its under side and mounted in any usual and suitable manund 3, with actual longitudinallyunoving Patented may 15, 154106.

rout and rear groundovheels bottom formed by apron 4, adapted to carry the load of manure in a rradualmanner toward a rotary spreader or heater-cylinder 5, mounted at the. rear of the main body in a transverse direction, as usual in the present type of manurc-sproaders The traveling apron aforesaid comprises a series of slats extendin the interior width of the main body and terribly connected to gether by cha1n-links 6 at their mid-length and respective ends. Said chaindinks just referred to have bearing in the usual manner upon rollers secured to the under irame of the main body to support the a non in proper position as the bottom of said body, and the middle links constitute the driving means for the apron and to this end areprovided with a series or additional links 7 to 'form an endless chain which passes around operating sprocket-wheels 8 and 9, journaled', respec tlvely, at the front and rear ends of the main body aforesaid.

10 is the usual transverse shaft arranged underneath and at the mid'length of the main body and provided with supporting-rollers 11, upon which the tailportion of the manure-oarrying aprons rides and is supported agains sagqin r during the last part of its movement of discharge and the corresponding first part of its movement of return. In the present improvement the initial riding of the apron into position upon the rollers 11 is insured by means of a link 12, arranged at the point of connection of the aforesaid additional chainlinks 7 to the tail end ofthe apron and provided with an inclined rib 13 on its under side adapted to ride upon the central one of the rollers H and lift the tail'ol" said apron above said rollers a distance sui'licient to prevent a catching of the tail of the apron against the rollers and avoid the consequent breakage of parts which might ensue.

The mechanism for imparting a rearward travel to the Insnore-carrying apron and for varying the speed of the apron in such rearward travel consists of the following means:

14 is a gear-wl1eel revolving in unison with a ground-wheel 3 of the machine and imparting motion in turn to a secondary gear-wheel 15, journnled upon a supporting-arbor us, scoured to the main. body 1 of the machine.

17 represents a series of annular gears ar ranged concentrically on the inner Face of the gear-wheel l5 aforesaid.

charge travel of the 18 is a pinion slidingly mounted upon a shaft hereinafter described and'adapted to be moved into engagement with either of the 1 series of annular gears 17 to receive there- 1 pivotally attached to one side of the main from different speeds of rotation in accordance with the speed at which it is desired to have the apron travel in its discharge movement.

19 is a sleeve connected to the hub of the pinion 18 in a manner which permits of an independent rotation of said pinion, and 20 is a connecting-link extending from said sleeve to a hand-lever 21 at the front of a slidingadjustment of said pinion in a convenient and effective manner in the operation of changing the speed of the rearward and disapron.

22 is an intermediate longitudinal shaft, at one end of which is the longitudinally-adjustable pinion 18 aforesaid and at the other'end a worm 23, adapted for operative engagement with a worm-wheel 24 at one end of the shaft of the rear apron sprocket-wheel 9.

25 is a bearing sleeve mounted'in slidable manner upon the supporting-arbor 16 aforesaid and forming a bearing for the forward end of the longitudinal pinion-shaft 22 aforesaid and adapted in one of its adjustments to maintain the pinion 18 in mesh with one or the other of the annular gears 17 and-in its other adjustment to move such-pinion clear of the path of such annular gears, so that the longitudinal adjustment of said pinion upon the pinion-shaft, as abovedescribed, can be effected to bring the pinion into proper relative position for engagement wit a particular annular gear 17, afiording the speed of revolution required Said bearing-sleeve is provided with a spiral rib 26 at one side of its periphery and with a complementary spiral recess 27 at one end, as shown in Fig. 3, for engagement with the operating-arm now to be described.

28 is an oscillating operating-arm journaled on'the arbor 16 aforesaid and provided with an inclined projection 29, adapted to have bearing enga ement against the inclined face of the spira recess 27 of the sleeve 25, so that when said-arm is oscillated in one direction the said bearing-sleeve will be forced outward to engage the pinion 18 with one of the annular gears 17 before described. Such arm is also provided with a hook-sh aped toe 30, adapted for engagement with the outer inclined surface of the spiral web 26 on the sleeve aforesaid, so that when said arm is oscillated in the other direction the bearing sleeve will be drawn. inward to move the pinion 18 out of its engagement with the annular gear 17 aforesaid.

31 is an operating hand-lever at the front of the machine; an 32 is a connecting-link extending'from said lever to the free end of the oscillating arm 28 to afford means for the j i l j 1 convenient operation of the parts by the oper ator at the front of the machine.

33 is a movable bearing carrying the rear end of the shaft 22, and 34; is a cam member body and provided with a cam-groove 35, engaging said bearing, as usual in the present type of manure-Spreaders. The arrangement of parts is such that an oscillation of said cam member in one direction will lift the worm 23 out of engagement with the wormwheel 24, while a reverse oscillation will place the machine 1 said worm and worm-wheel in operative enand by which the operator is enabled to effect gagement.

36 is a connecting-link attached to the cam member aforesaid and extended to the forward end of the machine for attachment to an automatic actuating means hereinafter more fully described.

The mechanism for imparting a return or forward travel to the manure-carrying apron consists of the following means:

37 is a pinion meshing with and receiving motion from the gear-wheel 15, before described. Such pinion is revolubly mounted on a supporting-arbor 38 on the side of the main body and is provided with a clutch member 39 on one of its faces.

40 is a chain-wheel arranged on the arbor 38 in adjacent relation to the pinion 37 and provided with a clutch nember il on its face, adapted for engagement with the clutch member 39, before described. Such chain-wheel is adapted to have endwise movement on said arbor in order that it may be moved into and out of operative engagement with the pinion 37 aforesaid.

42 is an endless chain connecting the chainwheel 40 with a companion chain-wheel 43 on one end of the shaft of the forward apron sprocket-wheel 8.

4.4 is a bell-crank lever pivoted-to the main body with one arm in operative engagement with the chain-wheel 40 and with the other arm connected to the rear end of a link 45, which in turn is connected to one end of a secondary lever 46, pivoted at the forward end of the main. body, as illustrated in Fig. 2.

47 is a hand-lever pivoted at its lower end on a stud 47 to the front end of the main body and operatively connected by a link 48 with the secondary lever 46 aforesaid.

49 is a spring connected to the lever 47 and adapted to draw said lever and the intermediate connections between said lever and the chain-wheel 40 in a direction which will release said chain-wheel from its engagement with the pinion 37 aforesaid, so that the normal tendency of said spring is to. maintain the mechanism for imparting a return movement to the manure-carrying apron in a dormant condition.

50 is a catch-piece secured to the mam body and behind which the lever 47 1s adapted to engage and be held when said lever 1s sewer end to the main body and provided with an intermediate angular bend or projection 52, arranged in line with the lever 47 aforesaid. and adapted in a forward swing to push said lever out of engagement with the catch-piece 50. The lower end of said arm is arranged in the path ,of the forward end of the manurecarrying apron in order that as the apron reaches the end of its return or forward move ment the said arm will be moved forward to release the lever 47 from the catch 50 to allow the spring 49 to automatically release the chain-wheel 40 from engagement with the pinion 3'7 and prevent further active move ment of the mechanism by which the return travel of the apron is attainedand as heretofore more fully set forth. i

is a ratchet-wheel secured to the shaft of the forward sprocket-wheel of the apron, and 54 is a pivoted pawl engaging said ratchet wheel to prevent a rearward movement of the apron except when the said pawl is .positively held out of engagement with said ratchetnvheel by mechanism hereinafter de scribed.

The mechanism for in'iparting rotary motion to the beater-cylinder in a readily-controllable manner consists of the following means:

55 is a gear-wheel revolving in unison with a rear ground-wheel 3 of the machine and imparting rotation in turn to apinion 56, mounted on a supporting-arbor 57 on the main body ina manner to permit of a limited endwise adjustment of said pinion for purpose hereinafter set forth.

58 is a chain-wheel arranged upon the or bor57 in adjacent relation to thepinion 56 and provided with a clutch member 59, adapt ed for engagement with a complementary clutch member (30 on the side of said pinion, as shown in Fig. 3. y

61 is an endless chain connecting the chain- Wheel 58 with a similar chain-wheel. 62 on one end of the shaft of the beatencylinder.

63 a lever pivoted to the main body with one arm engaging the hub of the pinion 56 aforesaid and with the other arm in operative engagement between a pair of spirally-arranged ribs of an operating member now to be described. i

64 is an oporating-arm journaled on a supporting-arbor of the main body with its hub portion provided with a pair of spirally-arranged ribs 65, between which one arm of the lever GS'has operative engagement, as above set forth.

66 is a forwardly-cxtending link which con nects the free end of the arm 64 with an actuating crank-arm which constitutes a member of the hereinafter-described mechanism, by which the operations of the different mechanisms of the machine are regulated and controlled.

67 is a pressure-comb consisting of the usual spring teeth or fingers projectin a carrying-shaft or back bar which is supported transversely of the main body in brackets or uprights on the sides of said body and in adjacent relation to the bcater-cylin der 5 of the machine. In the mamu'e-spreading operation of the machine the comb teeth or fingers aforesaid have a rearwardlydm clined position to form inconnection with the crown of the beater-cylinder a narrow discharge-throat for the manure to insure an ef fective separation of such manure in its passa e and previous to its discharge upon the field. The other position of said. comb teeth or fingers is a vertically de pending one in front of the beater-cylinder to form a shield for the same in the operation of loading the machine With manure. Such two positions of the comb teethor fingers are attained by an arm 68 on the comb-shaft, a connecting-link 69, and an operating-lever 7 O at the front end of the main body, and having a latch or ratchetlock 70", as usual in, the present type of ma nure spreaders.

The mechanism for effecting an interiocle ing control of the various mechanisms heretofore described and so that one mechanism is held dormant while an opposing mechan' ism is in operation consists of the followin means:

71 is a transverse rocleshaft journaled in front of the main body and provided with a hand-levcr 7 2, by means of which a rocking movement in either direction can be imparted to the rock-shaft by the o erator.

73 is a spring operative y connected to the rock-shaft 71, with a constant tendency to impart a turning movement to said roclc shaft and lever in a forward and downward direction.

74 is a spring-latch lever pivoted to the main body and adapted for holding engagement with the lever 72 against the stress of the spring 73 when said lever and its rockshaft are moved by hand in an upward and backward direction, as illustrated in Fig. 2.

75 is a crank-arm at one end of the rocksl'iaft 7] in operative engagement with the forward end of the link 66 of the heretoforedescribed mechanism for imparting rotary motion to the beator-cylinder.

76 is a crank-arm at the other end of said roclr-shaft in operative engagement with the forward end of the link 36 of the heretofore- .described mechanism for imparting a discharge or rearward travel tothe manure-carrving apron. The said crank arms 75 and 7 6 are so positioned with relation to each other from I that with a turning movement of the rock'- shaft in one direction both of the mechanisms just referred to will be brought into active operation, and with a turning movement of the rock-shaft in the other direction both of said operating mechanisms will be brought into a dormant or inactive condition.

77 is a link connecting the crank-arm 76 with the pivoted pawl 54 and adapted to lift said pawl out of engagement with the ratchetwheel 53 before the heretofore-described. mechanism for imparting a discharge or rearward movement of the manure-carrying apron is brought into active operation by a movement of the aforesaid rock-shaft.

' 7 8 is anarm pivoted to the main body and connected by a link 7 9 with a crank-arm 80 on the aforesaid roclcshaft. Such arm 78 is so arranged with relation to the intermediate lever 46 of the heretofore-described mechanism for imparting a forward movement to the manure-carrying apron that with the rock-- shaft 71 turned into a position to cause a rearward movement of said apron the said arm 7 8 will be lifted up into the path of the intermediate lever 46 to prevent a movement of said lever, and thereby lock the mechanism for imparting a forward movement to the apron in a dormant or inactive condition. In like manner and with the rockuirm 71 turned into a position which imposes a dormant condition on the mechanism for effecting a rearward movement of the apron and with the mechanism for imparting a forward movement to said apron in active operation the lever 46 will lay above and in the path of said arm 78 to lock the same against upward movement while such lastmentioned conditions prevail, and accordingly a dormant condition of the mechanism for imparting a rearward movement to the apron will be insured until the forward movement of the apron has taken place fully and such prevailing conditions changed by the impingement to the arm 5]. 52 againstthe lever 47, as heretofore set forth.

tion of the apron and adapted 81 is a rock-shaft arranged in a transverse direction near the front of the main body and provided with a depending arm 82, arranged in the path of the rear end or tail porto'be operated thereby as said apron reaches the end of its rearward or discharge travel.

83 is a rock-arm on'the shaft 81, having operative connection'by a link 84 with the free arm of the springdatch lever 72 of the here tofore-described mechnism for effecting an interlocking control of the various mechanisms of the manure-spreader.

85 is a projecting pin or stud carried by the link 66 of the beater-operating mechanism and located in front of the operating-lever of the pressure-comb aforesaid, and the arrangement is such that the lever 70 must be moved rearwardiy to place said comb in "quincuncial arrangement proper operative relation to the rotary beater efore the link 66 can have rearward movement to bring said beater into active operation. Y

The rotary heater 5 comprises in detail a pair of end spiders 86 and a central spider 87, to the circular outer rims of which are secured the circular series of rails or bars-88, which carry the teeth or picks 89 of the beater. In the present improvement said rails have an angular form in a direction lengthwise of the beater-cylinder, as shown in Fig. 7 of the drawings, and preferably consists of half-- rails arranged end to end at the central spider 87 and extending outwardly in an oblique manner to the respective end spiders 86 to constitute rails of the flattened V shape shown.

The teeth or picks 89 of each rail are stag gored with relation to the teeth or picks of the next adjacent rails, so as to present a ture in connection with their spiral or diagonal arrangement from the central to the portion of the beater as afforded. by the abovedescribed rails, provides a simple and effective beater construction in which the stress in actual operation is uniform and continuous, the liability to clogging and crowding greatly reduced, and the manure spread broadcast over an area greater than thetrack of the machine.

In the present improvement the pressurecomb heretofore referred to consists of a plurality of independent sections 90, preferably two in number and attached by hangerstraps 91 to a common supporting-shaft 92, carried by the brackets 93 of the main body, to which shaft the operating-arm 68, before described, is attached.

94 represents arms fixed to the shaft 92 by means of attaching-hubs and fasteningscrews or other usual means.

95 represents yielding connections ar ranged between the fixed arms 94 and the back of the comb-sections, each connection comprising a projecting bolt 96 on an arm 94, a spring 97 surrounding said bolt, and an adjustable nut 98 for regulating the tension of said spring. ith the described construction any one comb-section can yield under a local stress without requiring a movement of the entire comb, and in consequence the strain and drag upon the beater is correspondingly reduced and a more even and uniform manure distribution obtained.

The operation of the present manurespreader is as follows With the manure-carrying apron at the end of the forward travel and its dormant condition maintained by a forward and downward position of the lever 72, which insures a disen aged condition of the worm 23 and worm-w eel 24 and an enaged condition of the ratchet-wheel 53 and pawl 54: to prevent an accidental rearward of teeth, which feaeaojrei its raised and backward position to be engaged and held by the springdatch-M. Such movement of said lever causes a disengaged condition of the aforesaid ratchet-wheel ,53

and pawl 54 to permit a rearward travel of the said apron, an engaged condition of the worm 23 and worm-wheel 24 to effect such rearward motion of said apron, and, through the instrumentality of the arm 75, link 66, operating armfi i, and lever 63, a movement of the clutchmembers 59 and 60 into en: gagement to impart'a rotary motion to the beater-cylinder, after which a distribution of the manure over the field takes lace in an even and continuous 'manner. .efore the aforesaid movement of the lever 72 and the resulting movements of the other parts above described can be attained the arrangement of the lever 7 O in the path of the rearward movement of the lateral in 85 on the link66 requires that the said ever 70 shall be moved out of the'way, and in conse uence the adjustment of the pressure-comb cm a loading to a distributing position is positively insured before the operation of dis tributing the manure can commence. With the lever 72in the position above described the arm 78'is held up in the pathof the intermediate lcver 46 of the mechanism for imparting a forward travel to the manure-carrying apron by arm 80 and link 79 to lock said 'mechanism in a dormant condition while the rearward or discharge travel of said apronis taking place. With agradual rearward travel of the apron therear or tail end of said apron moves forward beneath the main body of the machine until it contacts and moves the depending arm 82', which in turn rocks the shaft 81 and arm 83 to release the spring-latch lever 74 from its holding en- ."gagement with the lever 7 2.

Said lever 72 then moves forward and downward in an automatic manner under the influence of the spring73. With such movement of the lever 72 a rocking motion is imparted to the rock-shaft 71, and in unison therewith the rock arm 75, through the intermediate mechanism before described, causes the clutch members 59 and 60 to separate, with a consequent stoppage of the positive rotation of thebeater-cylinder. At the same time the rock-arm 7 6, through the link 77, lowers the pawl 54 into'engagement with the ratchetwheel 53 to prevent accidental retrograde movement of i the manure-earrying apron, and said rock-arm 761; throu h'the'intermediate mechanism heretofore escribed, causes the worm and worm-wheel to separate with a s'to page of the rearward or discharge travel of t e apron. Concurrently with said operations above describedthe arm 80 and link 79, moving in unison with the lever 72, push the arm 78 down out of the path of the intermediate lever 46, before referred to. The operator now draws thelever 47 in an opposite direction to the stress of the spring 49 and causes an engagement of said lever with the catch-piece 50. In such operation the lever, through the link 48, intermediate lever 46., link 45, and bell-crank 44, moves the clutch members 39 and 41 into engagement to impart a return or forward travel to the apron through the chain 42 and chain-wheels 40 and 43 and forward apron sprocket-wheel 8. During such forward travel of the apron the intermediate lever 46 lies in the path above the free end of the arm 78 to lock the same in its downward osition and insures a'dor mant condition of the mechanism for attaining a rearward movement of the apron while the above-described forward travel of said apron is taking place. As the forward end of the apron reaches th limit of its forward travel it impinges against and moves the pendent arm 51, which in turn effects a dis engagement of the lever 47 from the catchpieoe S'tland enables the spring '49 to draw said lever transversely a vay from said catchpiece. Such movemen of the lever 47 causes a separation of the clutclrmembers 39 and 41 through the intermediate mechanism above described, and a stoppage of 'the further forward movement of the a ron, leaving the parts in-a position fora fres 1 cycle of the operations ust described. In effecting a change in the s eed of the rearward or dis char e travel 0 themanure-carrying apron the mud --lever 31 is moved forward and through the link 32 and operating-arm 28 effects a movement of the bearing-sleeve 25, and with it the' pinion 18, away from the annular gears 17, so that said pinion will be entirely clear of said an'n'ular gears. The lever 21 is manipulated by hand to draw the pinion 18 into alinem'ent with the particular an- 'nular gears 17 with which'it is desired to have en agement, after which the lever 31 is operate vin a reverse direction to that above described to move said pinion into operative engagement with the particular annular gear.
