GRAIN-SHOCKING MACHlNE.

.This-inyentlon relates to grain-shocking machines, p g The objects ofthe in'ventiofi areto improve and simplify, the .bonstruction -of such machines; furthermore, to increase their efficiency in operation and'to decrease the ex- ,pense attending theirmanufacture.

With the foregoing, and other objects in -.-view, which will appear'as thejdescription proceeds, the invention resides in the c0mbi- "nation and arrangemnet of parts aud in,

the details 0L construction hereinaftef de scribed and claimed, it being understood that changes in' the precise embodiment of inven' -tion herein disclosed can be made within the I scope of the following claims without departing fromthe spiritof the invention or sacriand 10 are detail views.

Like reference-numerals indicate I corresponding parts inthe different figures of the drawings.

The shocking-machine of the present invention is constructed with any suitable form of framework or platformA, which is i supported by means of alarge ground wheel 1 and a small carrying-wheel 2. The platform. A of the machine along one side thereof is secured to a binding-machine in an suitable manner, such as by means of the rackets (Shownin Fig.2. The ground-wheel 1 is journaled in a rectangular frame 4, which is mounted for vertical sliding movement in a slightly larger rectangular frame '5, the lower ends of which are provided with flanges 6, bolted or otherwise suitably securedv v Specification or Letters Patent.

to the platform A. The stationary frame 5 has formed in its sides vertical slots'7, as

:shown in Fig. 1, to receive bolts 8,; which-are secured to the slidable frame4 i'reany suitable manner. For the purpose of permitting iyieldingupward movement of the frame 4 jand ground-wheel 1 with respect to the frame [53 oil-spring 9 is interposed between the upper end of .the framed and the frame 5. Rigidly secured -to the upper end of the slid- Manama-4 and extending loosely upward through the frame 5 is a bolt 10, which passes through the center-of the coil-spring 9 and is provided at its upper end with an adj ustingnut 11.. By tightening the nut 11 the frame 4 will be drawn positively upward in the frame 5', and said bolt lO'will limit thedownward movement of the frame 4 without .pre-

{venting the coil-spring 9 .from permitting an upward yielding movement thereof whenever the wheel '1. strikes an obstruction. It will be obvious, therefore, that by tightening the nut 11' the platform A can be drawn downward closer to the ground whenever desired.

Thernnveying meansfor receiving a sheaf of grain'fioirr the binder and carrying the same into the shocking-chamber, to be here inafter described, preferably consists of a pair of endless aprons o; belts 12 13, which are slightly inclined from the vertical, as

shown in Fig. 1, andareadapted to form between them a channel 14, along which'the sheaf of grain is carried, it being understood that the sheaf is fed from the binder in such manner that'it will enter the channel '14:

in an approximately vertical position with the heads of the grain upward. The means 7 for-operating the endless aprons 12'and 13 so that their inner portions will travel inthe same direction preferably consists of'a sprocketchain 15, which is suitably connected with the vertical shafts of the belts 12 and. 13.

The s rocket-chain 15' is operated by means of a s aft 16, journaled in a bracket 17 upon the platform A. (See Fig. 1.) The shaft 16 is provided with a bevel-gear 18, which is operated by means of a bevelgear 19, said bevehgear 19 in turn being rotated by a sprocket-chain 20. The sprocket-chain 20.

"ground-wheel 1.

' a rotary member B, comprising a,vertic ali shaft 29, to the lower end of which is secured a plurality of radial"blades ,30, said blades being preferably 'connected'with'the shaft 29 by means 'of spring brackets or arms '31. In the embodiment of invention illustrated four radial blades 30, areemployed; so as to divide the shocking-chamber 28 into four each compartment formed by the blades sections or compartments, although. it is to be understood that a; greater or, lesser number of blades 30 can be employed Each of the compartments formed by the radial blades 30 in the shocking-chamber 28in the present instance is intended'to hold three sheaves of grain,--so that a shock when formed will; containtwelve sheaves of. grain. As

willhold' only three sheaves of grain, it will be apparent that the rotary member, con sisting of said radial blades, must be rotated one step each time three sheaves of grain have been fed to the shocking-chamberpso,

A T that an empty compartment will be disposed s5 pp osite the door 27. A v ,he means for-operating the rotary mem- 'ber in the shocking-1 chamber 28 each time three sheaves of grain have been fed to said chamber preferably comprises the following.

o mechanism: Journaled iii bearin -plz ites 32 u on stationary supporting mem ers at t e upper-ends of the endless belts 12 and 13; v

I as shown in Figs. 1 and-,2, is arock-shaft'34,

which is provi de'd with a rigid depending arm 35,-the-lower end of which is broadened, as shown at 3,6, and is located in the channel 14 between the endless belts 12 and 13',so that each time a sheaf passes along the channel 14 its u per end will engagethelower end of the rigid arm 35"and rocktheQshaft 34. Extending upward from the shaft 34 is arigid arm 37, with the upper end 'ofwhich is connected a flexible element 38, that extends upward and is connected with a lever 39, loosely fulcrumed upon a stud shaft 40, which i%suitably journaled in' a supporting:- frame 41-. The lever 39-at its free end is normally drawn npward into raised, osition by means of recoil-spring 42. It wil be understood that each timea sheaf of grain moves theahgh the channel 14 arid operates the arm 35 the iever 39 will be drawn downward-"against the tension of the s ring 42,

and after the sheaf has passed out 0 contact with the arm 35 the spring 42 serves to restore said arm to roper position to be engaged by the next sheaf.

Rigidly mounted upon-the, stud-shaft 40 is a disk 43, having three ratchet-teeth or cam members 44, which are so arranged that each time the-lever'39 is moved downward by a sheaf of grain it will engage one of the cam members 44 and vwill rotate the disk 43, and

consequently the-shaft 40,"one step, after.

which the spring. 42 will draw the lever 39 upward into position 'to engageflthe next cam member, it beingunderstood 'that'the loose mounting of said lever upon; the stud-i shaft 40permits it to ride upward over the.

inclined faces of the cam members 44 and that the.spring 42 draws it in behind each cam member,"so as to engage the same on its downward movement. Rigidl. with the stud-shaft40onthe si e of the supporting-frame 41 op.posite' the disk 43 is a connected. c

ratchet-wheel 45, with which cooperates a 'pawl. 46, mounted upon thesupportingframe 41. The ratchetrwheel ifi is provided with an; eccentrically-mounted pin-47., which duringeach rotation-of the ratchetrwheel45 is adapted to engage and rock eleven 48, fulcrumed at its upper end 49-loosely$upon a shaft 50, which is journale'd in the supporting frame 41, as shown. The lever. 48'is drawn normally to the right in Fig. 1 by means of a coil-spring 51, so thatit. will be held yieldingly in con'tactwithth'e eccentric-pin 47 on the ratchetwheel '45. Atits lower end the lever 48 is connected witha'link 52, which is suitably secured'to a-bell-crank lever 53, .ful crumed upon a bracket. 54, Thebell-c'rank lever 53 is bifurcated, as indicated at' fgi Fig. 2, and is engagedyby a; clutch mem.- ber 56,- splined upon' themain shaft 21 Loosely mounted :uponthe mainshaft 21, a d+ jacent the, slidable clutch156, isa clutch 57;

When the lever 48 is operatedby the-eccentric+pin 47 on the ratchet '45, the bell-crank lever 53is rocked,.so as to throw the splined clutch member, 56 into engagementv with the ,l'oose lutch member 57, andthus-cause said v member "57 to rotate withvthe Inainshaft- 21;.

Secured/upon the looseq clutch memberr57 is, an. eccentric disk, 58 which when the clutchmember ,57 is rotated by the shaft "21 is ad a'pted to contact with and rock to theleft in F 1 a lever; 59 which is journaled'at itsg lower end 60 'upona fulcruml-plate 61 upon the platform-A. p The lever 59 at its upper endis connected with a link-"rod 62, having on the rear, end

thereof a hookportion 63, whicl1 is adapted to engage one of the-teeth of a ratchet-wheel 64, mounted rigidly upon the shaft 2901? the It will be obviouszthat when the splined clutch member 56 is thrown rotary member B.

into engagement with the loose clutch memher 57 andhhe eccentric 58-is rotated to rock, the lever 591the linli'62 wilt bedrawn to thethus move the rotary member B, as described. I

F or the purpose of moving the link-rod 62 to the right in Fig. 1 after it has operated the rotary member B, so that the portion 63 of said. linlerod will be in position to engage the next tooth of the ratchet-wheel. 64, the lower end of the lever 59 is formed with an upwardly-extending crank portion 65, which fits over a fiat spring 66, as shown in Figs. 1 and 2. The u ward pressure of the spring 66 on the cran; portion 65 of. the lever 59 throws said lever 59, and consequently the link-rod 62, to the right in Fig. 1 as soon asa sheaf of grain by rocking the arm in the channel 14 has stopped the further rotation of the member B by moving the eccentricpin 47 away from the lever 48, and thus permitting the spring 51 to pull said lever 48 to the-right in i ig. 1, whereby the'bell-c'rank lever 53 is caused to disengage the clutch member 56 from the clutch member 57.

As previously intimated, each time twelve sheaves of grain have passed through the channel 14 between the conveyors 12 and 13 the rotarymember B will have been given four movements and will have made one complete revolution, so that the shocking chamber 28 will be filled with twelve sheaves of grain. At this time it is desired that the rotary member B shall be moved bodily upward within the shocking-chamber and that simultaneously a rearwardly and upwardly swinging door connected with the shocking chamber and a pair of sliding doors forming the bottom of said shocking-chamber shall be opened, so that the shock, consisting of the twelve sheaves of grain, shall be permitted to drop downward out of the shock ing-chamber 28 and to be left in proper position upon the ground.

The means for movingthe rotary member B upward when the shocking-chamber 28 is filled-will now be described. Splined upon the shaft 29 of the rotary member B is a gearwheel 67, which is in mesh with a similar gear-wheel 68, journaled upon a bracket 69, which is supported upon a crosspioce 70, held in proper position upon. the supporting frame 41 by means of adjustable collars 71. It will be understood that each time the rotary member B has made one complete revolution each of the gear- wheels 67 and 68 will also have made one complete revolution. The gear-wheel 68 on its upper surface is provided at one point with a projection 72,

which is adapted once in every revolution of saidrgear-wheel 68 to wipe under and rock a lever 73, fulcrumed at 74 apon a supportingarm 75, connected with the frame 41. At its upper end the lever 73 is pivotally connected with a smaller lever 76, fulcrumed at-7 7 upon.

the supporting-frame 41 and connected at its upper end with a clutch member 78, which is splined upon the shaft 50. Loosely mounted upon the shaft 50 is a clutch member 79, which is rotated in a continuous manner by means of a sprocket-chain in gear with the 8 main shaft 21, which, as before explained, is continuously rotated-from the ground-wheel '1. Each time the rotary member B and consequently the gear- wheels 67 and 68 make one complete revolution, so as to rock the lever. 73, the splined clutch member 78 is thrown into engagement with the loose clutch member79, so that the shaft 50 is caused to be rotated by the clutch member 79. Mounted rigidly upon the'shaft 50 is a large cam 81, which, as shown in Fig. 4, is disposed between a pair of idle wheels 82, journaled on stud-shafts 83 within a vertically-movable yoke 84, which is slotted at 85 for the passage of the shaft 50. Theyoke 84 29 of the rotary member B. It will be apparent that at the end of each complete revolution of the rotary member B when" the has a swivel connection at 86 with the shaft clutch member 78'isthrown into engagement with the clutch member 79, as described, and

the shaft 50 is rotated the cam 81 will raise the yoke 84, which in turn will raise the rotary member B, so as to draw the blades 30 upward out of engagement with the shock in the shocking-chamber 28 At the moment that the rotary member B is raised in the manner described it is proposed to open the sliding doors, which formthe bottom of the shocking-chamber 28, and also to open the swinging door, which forms the rear end of said shocking-chamber, so that the shock can drop to the ground and the machine can move forward, so as to leave the shock in proper position.

The construction and arrangement of the rear and bottom doors of the shocking-chamber 28 and the means for opening said doors when the rotary member B israised will now be described. The reference-numeral 87 indicates a swinging door, which is p'ivotally mounted at 88 upon the rear end of the shocking-chamber 28. The door 87 is provided at its lower end with a heavy counter;

weight 89 and at its upper end with a rigid upwardly-extending arm 90. Secured to the arm 90' is a flexible element 91, which is wrapped arounda drum 92 fastened uponan auxiliary shaft 93, which is journaled in uprights194 upon the platform A. The auxiliary shaft 93, as shown in Fig. 2, at the end thereof opposite the drum 92 is provided with a second rigid drum 95, around which issame from the drum 92.

wrapped a flexible element 96, which, as

shown in Fig. 3, extends downward through- 'The doors 101 and 103 are adapted to slide back and forth inguideways 104, so as to open and close the lower end of the shocking chamber 28. Connected with each of the sliding doors '101 and 103 and with each of the arms 100 and 102 is a pair of coil-springs 105, the tendency of which is .to draw the doors 101 and 103 into opened positionand away from each other. The wei ht 89 upon the swinging-door 87 of the shoc ing-chamber 28 is sufficiently heavy to swing said door 87 into closed position, thus drawing upon the flexible element 91 and unwinding the As the flexible element 91 is unwoundfrom the drum 92 by the weight 89 the flexible element .96 is'wound upon the drum 95, thus drawing the sliding Wlll be understood, there doors 101 and 103 into closed position against the tension of the springs 105. It ore, that the -weight 89 serves not only automatically to hold the swinging door 87 in closed position, but also the sliding doors 101 and .103.

For the pu ose of opening the swinging door 87 and t e sliding. doors 101 and 103 when the rotary member B is. raised the following mechanism is employed: Rigidly secured at 106 to the yoke 84, as shopvn in Figs. 1 and 2, is a depending arm 107, which, as shown in- Fig. 5, is provided at its lower end with a latch 108, fulcrumed at 109 and having a rearwardly-extending arm 11.0 and 4, pin 11.12, mounted on the arm 107.- As the a slot 111, through which extends a limiting,-

arm 107 moves upward with the yoke 84 the face '1 13 of the latch'108 engages and rocks a lever 114,{,WhlOh lS fulcrumed at 115 upon a supportingmrm 116, secured at 117 to the cross-piece of the frame. As the lever 114 is rocked upward at its rear end by the latch i 108 the forward end of said lever pushes downward upon a link-rod 118, which is piv v ."otally connected with the lever 1 14, as shown at 1 19. Secured to the lower end ofthe link rod 118, as shown in Fig. 2, is a bifurcated wedge member 120, which straddles the shaft 93 betweena fixed collar 121 and a clutch member 122, which. is splined on said shaft '93. As the wedge member 120 is forced d'ownward by the rod- 1 18 it pushes the clutch member 122 intoeng'agement with a clutch member 123-, which is loosely mounted on the shaft 93 and is continuously rotated by means Ora. sprocket ehain 1 24 fromthe con tinuousl-ywotated main shaft 21. It will be obvious, therefore, that as the yoke-84 is raised, in themanner described to elevate the rotary memb r the wedge 120 is movedengagement with the ,clutch: 123, whereby the shaft. 93 is rotated in such manner as to wind the flexible element 91 upon-the drum 92, so as to open the rear door 87 and at the same time to pay-off the flexible elementv 96 from thedrum 95, so as to permit the springs 105 to exert their influence to open the slidingdoo rs 101 and 103. As the operations of raising the rotary member B and opening the swinging door 87 and the sliding doors 101 and 103 take place simultaneously, it will be downward, so as to throw the clutch 122 into obvious that theshock, consisting of the twelve sheaves in the shocking-chamber 28, will be dropped, to the ground when the sliding ddors at the bottom of said chamber are entirely opened and that the swinging door 87 b'yreas'on of the fact that it has been raised into opened position will clear the upper end of the shock. ,When the yoke 84 has reached its highest position, the arm 110 of the latch 108 comes into contact with a 'rigid sto member 125-, which is secured to the mac inc-frame in any suitable manner and is formed with'a bent end 126. The engagement of the" arm 110 with the bent =por-' tion 126 of the stop member 125 serves-to trip the latch 108 out of engagement with the lever 114. Said lever 114 is then immediately drawn downward into its lowermost position by a weight 127, which'is secured to said lever, asshown in Fig. 1. The downward .movement of the lever 11.4 draws-the wedge upward, so as to release the clutch member 12 2 from the clutch member 123,

thus stopping the rotation of the shaft 93 8 while the door 87 is in raised position and the doors 101 and -103 arein openedposition.v

The weight 89 on the door 87 then causes said door to move downward to closed position, thus rotating the shaft 93 through the flexible element .91 andeausing th e flexible element 96 to draw thesliding doors 101 and 103 into. closed position againsttlie action of the springs 105.

As previously explained, it is proposed thatthe lever 73 in Fig. 2 shall be employed for throwing the shaft 50 into operation to raise and lower the rotary member 13 when the shocking-chamber 28 contains twelve sheaves of grain. It may be here explained lution each time. three sheaves of grain have been fed to the shocking-chamber.- After the last three sheaves have beenfed to the that the gear-wheel-68 makes a quarter-revo shocking-chamber the gear-wheel .68 makes the last quarter of its revolution and during this last movement the projection 72 first rocks the lever 73, so. as to throw the clutches, 7 8 and 79. into engagement with eachother' and hold the same in said engagement un 11 the shaft 50 has made one complete revolutiongthereby raising and lowering therotary member 3. The projection 72 then slips fr'emi under the lever 73 and av spring 128 rocks said lever, so as to move" the clutches 78 and 7 9 out of engagement, with. each other. It will be understood, therefore, that the rotation of the clutch member 79 mustbe sufficiently rapid to give the shaft 50 one complete revolution during the limited time that the projection 72 holds the clutches 7 8 and 79 in engagement with each other before slipping from under the lower end of the lever 7 3 at the end of the last quarter-revolution of the gear-wheel 68. v

The reference-numeral 129 in Fig. 3 indicates a portion of a binder to-which the brackets 3 are secured, and the referencenumeral 130 indicates a brace-rod which is secured to the outer forward corner of the shocking-machine and extends inward, so as to be connected with some suitable portion of the binder. I

The improved shocking-maclfine of the present invention is strong, simple, durable, and inexpensive in construction as well as thoroughly efficient in operation. The ro-' tary member Biserves to hold the different sheaves in proper position in the shocking chamber 28 to form a shock, and the frustoconical sha e of the shocking-chamber28 serves to ho d the upper end of the shock in contracted position. Furthermore, I as the doors 101 and 103 are drawn apart to permit the shock to fall outof the shocking-cham- I her they serve to draw apart the lower ends of the shock, so as to give the same a' broad base, and thus hold it in proper position upon the ground.
