T 0 all whom it may concern.'

Be it known that I, GEORGE HANsLIoK, a citizen of the United` States, residing at Lafayette, in the county of Nicollet and State of Minnesota, have invented certain new and useful Improvements in Loading- Machines; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the class of loading and unloading, and more especially to those devices having a raised or inclined track o`r platform and dumping means at the upper end thereof; and the object of the invention, broadly speaking, may be said to be to provide improved means actuatedautomatically or manually whereby the windlass is reversed when the scoop is dumped and the latter is `retracted to the point of starting. In the following specification and claims I have described this invention as adapted more particularly for loading manure onto wagons, although it will be clear that dirt, gravel, or other material could be brought from a distant point by and in the scoop, carried up the platform, and dropped into a car or any other suitable receptacle which was disposed beneath thc rear end of the framework and platform.

The invention is typically illustrated in the accompanying drawings wherein-L Figure 1 is a side elevation of this machine complete, showing the scoop in the act of being dumped; Fig. 2 is an elevation from the opposite side, showing the scoop as drawn off the platform; Fig. 3 is a plan view with the upper end of the platform omitted; Fig. 4 is an end elevation; Fig. 5 is a perspective detail showing most of the working partsof this machine; Fig. 6 is a perspective detail of the upper end of the framework and platform, illustrating the automatic dumping mechanism and its connectio-n with the automatic reversing .mechanism; Fig. 7 is an enlarged sectionaldetail of the driving pulley and clutch, and Fig. 8 is an end elevation thereof.

In the drawings a pair of sills 1 support an upright framework 2 which carries obliquely disposed converging side strips 8 between which is an inclined plat-form 4 lead ing from the level of the earth upward but terminating short of the upper ends of the strips 3 so as to leave between them an opening 5 for dumping purposes. Coacting with this platform is a scoop 6 which does not differ essentially from those now in common use excepting that it has a cross bar 7 adapted to ride onto the upper edges of the strips 3 when'i the scoop nears their upper ends, and at a proper point just in advance (below) said opening the strips carry plates 8 on their inner faces whose upper edges 9 are inclined more steeply than the upper edges o f the strips so that in effect they act as cams to lift the extremities of the cross bar on the scoop and to tip the latter and cause it to dump through the opening 5 while also preventing the scoop itself from falling through that opening.

The scoop-actuating mechanism includes a windlass 10 (preferably made double as shown) journaled in the framework, and from one drum of which leads a rope 11 passing over guide pulleys 12 and 13 and finally over a main pulley 14 at the upper `end of the side bars and branched and connect'ed as at 15 with the scoo-p; and this may be said to be the drawing rope. rope 16 leads from the other drum of the windlass over a guide pulley 17, along over the platform and to a distant point where it passes around? a pulley 18 attached to a. stump or other fixed object, whence it returns to and is attached at 19 to the vback of the scoop; and this may be said to be the retracting rope. Obviously when the windlass is t-urned in one direction the scoop will be drawn up the incline because of the direction in which the drawing rope is wound around the windlass, and when the latter is turned in the opposite direction the retracting rope will draw the scoopV back down the incline and over the earths surface to a point remote from the machine asA far as the pulley 18 may be disposed. Here the scoop may be lled by hand, or it may be guided on its return movement toward the platform so that it will automatically scrape up t-he manure or other substance being treated, all as will be clearly understood Without further description.

The driving mechanism for the windlass comprises a source of power (a gasolene engine G will answer, as indicated in the drawings) belted to a pulley 20 which is loose on the main shaft 21 journaled as at 22 in the framework and having a clutch 23 adapted Another to be engaged said pulley-by means of a lever 24 from which a link 25 leads to a hand lever 26 operating over and in conjunction with a toothed segment 27 4secured to one of the sills adjacent the front end of.

the platform, `and it is obvious that an operator standing there ,can manipulate ,the

lever so as to throw the clutch into or out of engagement and therefore connect the main shaft with the source of power at will.

rlhe other end of thevmain shaft is ljour-1 naled as at 30 in a movable bearing conout of meshtherewith ywhen theplateisswung in the Aopposite direction.-

Journaled ona sub-shaft 35at-thelow'er end ofthe plate 3l (or movable bearing) is a long gearpinion v36 which is in. constant mesh with the gear pinion-33 androt-ated thereby, and the long pinion is moved away.

from the gear wheel34 when the pinion 33 is in mesh therein, andviceversa-,`so that the swinging of the movable bearing 31lalternately engages the pinions 33 and 36'with the gear34 on the windlass and consequently rotates the latter in. opposite direct-ions'. This detail might well be called the shifting or reversing mechanism.v The manualcontrol for said reversing mechanism consists of a rod 40 connected with the upper end of the movable bearing 31 and leading thence to .an arm 42 at the upper extremity of an upright rock shaft 43 mounted in bearings 44 on the frame and having a second arm 45 at its lower end, and this arm is connected by a rod 4G with a hand lever 47 which is by preference mounten in the framework adjacent to the segment 27 so as to be within reach of the same operator. By moving this hand lever in one direction he swings the .movable bearing in one direction, and vice versa; and hence he has control of the reversing mechanism above described.

yThe automatic control for the reversing mechanism is constructed as follows: The drawingvrope, near its point of attachment tol the windlass, has a knot 50 too large to pass through .an eye or loop 5l through which the rope passes between the windlass and the pulley l2, this loop being formed at the inner end of a lever 52 pivoted at 53 on the framework, and to said lever is linked as zit-54 a rod 55 whose other end is either directly attached to the upper extremity of the movable bearing 3l or connected therewith .through the instrumentality of the mechanism described below. Therefore when the drawing rope is nearly unwound the knot 50 moves the loop lever 52 which, through the connection described, causes the movable bearing 3l to on itspivot 32 ano reverses the direction .of rotation of the wmdlass automatically. Near its point of "attachment to the'scoop the drawing rope Vhas xanother knot too large to movel through an eye or loop 61 throughwhich v this:ropempasses between the scoop and the pull'ev14', the loop being carriedl by'aj lever.

' 62 pivoted atlfincne of the side bars 3, and this lever is connected by a rod (i4-to the outturned upper end Glof a rock shaft 66 journaled. in bearings 67. o'n anwupright'of the framework-and having a second arm 68 at' its lower extremity Iconnectetil ,by-ailink 69 with Ethe movablebearings Blf either di-v rectly-.or through .the instrumentality of mechanism described zbelow, Therefore whenv -the=scoop reaches ,a dumping position the knot: 60l moves the loop lever 62 which, thro-ugh theconne'ctions described, causes the movable bearing 31 teswing on its pivot 32 with= the resultvthat thedirection ,0f-.rotation of the. windlass isvautomatically lreversed;,;i- .i

l-T-he oper-ationof so much-of thy/machine as has been describediisras follows: The parts being set upas shown inthe drawings and lthe driving pullev-20 connected witha source o-fpower such as the gasolene .engine,-for vinstance, when*v the 4operator closes the clutch the power shaft begins to revolve in the direction ofv the arrow. /Thefhand lever 47 -will at first-stand upright tohold the reversing mechanismat a neutral point with bothpinions 33: and 36 ,out of en gagement with the gear -wheel 34, so that the power shaft does'y not at first rotate the windlass at all.r vAssuming now that the scoop lies upon the platform.. When the yico operatordraws this hand lever 'forward the I pinion 36 is engaged with the `gear 34-on the windlass and the latter isrotatedina direction to draw upon the ret-racting rope so that the scoop moves down the platform and out Iover the ground toward the pulley 1-8. Having reached that point, unless the operator again throws the reversing mechanism to a neutral position the knot 50 will automatically reverse. the mechanism and the scoop will return tothe platform; and this occurs where the scoop is used to gather up material such as sand or gravel. If however, the material being handled is in a distant pile and it is desired that the scoop remain stationary while it is filled, the operatcr will throw the reversing mechanism to a neutral position at this time until the scoop is filled, and then move his hand lever in the opposite direction to engage the pinion 33 with the windlass gear 34, when the windlass will rotate in the other direction and the drawing rope will cause the scoop to be moved over the ground and up the platform. As it reaches its highest point its cross bar moves over the cams 8 and the scoop is automatically dumped through the the windlass will commence rotatin opening 5 at the upper end of the platform and into a wagon or whatever vehicle stands beneath.' Here-agaim if the operator does not interfere, the other knot 60 will automatically throw the reversing mechanism s0 that as soon as the scoop has been dumped 4 in the wi l again pulley 18 for opposite direction and the scoop be drawn outward toward the a renewal of the operation.

In connection with the primary or essential features of my invention described above, I preferably make use of the following amplications'or 'refinements in order that the machine may befp'ositive in its action and that the delays incident to accident may as far as possible be avoided: It sometimes occurs that the nature of the material bein handled or the manner in which it is loaded into the scoop prevents the latf ter from dump-ing accurately even 'though' its cross bar travels up the 'cams under the impulse of the drawing rope. The scoop will dump, but what I mean to say-i's that if the reversing mechanism be actuated automatically the scoop must dump quickly or else its direction of movement will be reversed before all of the material has been dropped through the opening 5. Therefore I preferably employ a bail whose center is pivoted in eyes 71 beneath the upper ends of the side bars 3 and whose arms rise alongside the same, have eyes 74, and at their upper extremities hooks 7 5 so shaped that the ends of the cross bar 6 will move onto them as the scoop passes up the platform, and after engagement therewith the rear end of the scoop will be raised by the swinging'of the arms of the bail. Itis even possible to connect said arms orv one of them by means of a link 76 leading from one or both the eyes 74 to the loop-lever 62, and when the knot 60 swings the latter this link will cause the movement of said bail around its pivotso that the scoop will be dumped in any event. A lock is by preference also employed for holding the movable bearing 3l in either of its extreme positions, for itl will be remembered that at times this machine is subjected to great strain and there is considerable possibility thatI the teeth of the gear wheel 34 will disengage those of one or the other of the pinions 33 or 36 automatically or accidentally. This lock consists of a bar 80 having one ,end pivoted at 81 to the movable bearing 31 above its journal 30 and the other end pivoted at 82 toa rocking link 83 as best seen in Fig. 5.A The lower end of this link 83 is in turn pivoted at 84 to a sliding bar 85 movable in guides 86 on the framework and having its inner end turned downward as at 87 and linked as at 88 to a rock lever 89 whose through upper extremity is in turn pivotally con, nected as at 90 with the rods 55 and 19 r'lo i plast the link and attached as at 96 to some point in the framework, so that the link may have the motions yet to be described -as the spring will exert a constant pressure tend-` ing to hold the rocking link in either of its two inclined extreme positions. With this construction of parts, the movement -of either loop lever as automatically caused by the knot in the rope` is-ilmfediately communicated to the rock lever 89 and by the latter vthe link 88 to the sliding bar 85 which forthwith commences to move; but the movement 'of the rock lever is, by reason of the loop 92 in the link 93'between it and the movable bearing 31, more tardily communicated tothe latter, -and by it to the bar 80 which is moved in the oppo-site direction to the bar 85, butv at a later time. The `result is that the two extremities 82 and 84 o-f the rocking link are moved in opposite' directions. but at different times, although finally the uppermost will move over the lowermost and will carry with it the upper end of the spring 95, so that once the lever does position it quicklymoves to its opposite inclined position and the 'reversing action is effected rather suddenly'.- By the use of this lock it is practically impossible for the reversing mechanism to stop on a dead center 105 or neutral point, and when it is desired that the main shaft shall not drive the windlass in either direct-io-n the operator will be compelled to hold (or to set) the hand lever 47 pass an upright or vertical to such position that both the movable bear- I ing 31 and the rocking link 83 will stand strictly vertical. I consider the employment of this amplification or reinement of advantage to a machine of this character, not

only because the spring-actuated rocking 1,15

link when in either of its extreme inclined positions holds one of the driving pinions in reliable mesh with the driven gear, but because the reversing-mechanism when set in motion by one of the knots engaging the proper loop-lever is moved by this mechanical detail in such a way that the change of direction of rotation is effected quickly. Furthermore, I consider it of advantage to make it diicult for the operator to setA the reversing mechanism at a neutral pointrather would I prefer that he manipulate the other hand lever 26 to open the clutch and disconnect the driving shaft from the motor, when he desires thatthe operation of this machine shall cease, for when it is in operation I prefer that the scoop be mov- 'ing in either' one direction or the other.

All partsl of this machine are of the desired sizes, shapes, proportions and materials, and modifications and changes may made in the details without departing` trtiin the principle of the invention. In .some instances, as where a cheaper machine is desired. the auxiliary scoop-dumping mechanism or the lock for the reversing mechanism may he omitted', orp iaps both might be dispensed with if pre .ii-ed. As suggested above, this machine is capable of use in a number of ways, and where I speak of a scoop throughout the specification it will be understood that any device for conveying the material to be handled might be employed, as the term scoop is used to' conform with the typical illustration in the drawings.
