HOISTING-BUCKET.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed September 9, 1915. Serial No. 49,683.

To all whom it may concern Be it known that I, VVILLIAM THOMAS, a subject of the Emperor of Germany, and a resident of Beatrice, in the county of Gage and State of Nebraska, have invented a new and Improved Hoisting-Bucket, of which the following is a full, clear, and. exact description.

My invention relates to a hoisting device designed particularly for the purpose of receiving grain or similar loose material from a wagon from which it is unloaded, and conveying the material into a crib, granary, bin or similar storage receptacle, and the object thereof is to provide a particular construction of hoisting bucket into which the grain or other material is permitted to run, after which the bucket is hoisted by means of a suitable hoisting rope and is caused to travel along a track provided in the granary or building into which the material is to be transported and wherein it is stored.

The particular features of construction wherein my invention consists will be hereinafter referred to in detail as the same is described.

With the above and other objects in view, my invention consists in the improved grain hoisting bucket and hoisting means therefor illustrated in the accompanying drawings described in the following specification and particularly claimed.

Referring now to the drawings wherein the preferred embodiment of my invention is illustrated, Figure 1 is a view showing my improved hoisting bucket in side elevation and showing also the hoisting and controlling ropes associated therewith; Fig. 2 is a view illustrating the hoisting bucket and the ropes for hoisting and controlling the same, and a track arranged within a building into which the material is to be carried; Fig. 3 is a view showing a section of my improved hoisting bucket upon a horizontal plane indicated by the line 33, Fig. 1, looking down; Fig. 4: is a view of my improved hoisting bucket taken upon a vertical central plane indicated by the line 4 4L, Fig. 3; and Fig. 5 is a view showing a section taken upon a plane at right angles to the plane of Fig. 4, and upon a vertical plane indicated by the line 5-5, Fig. 4, looking toward the left.

Referring now to the drawings, the reference numeral 7 designates two parallel support ng s sp ed part from one other and which bars support the bucket and through which the same and its contents are to and holding the vertical members 8 and horizontal members 7 at a proper angle with reference to one another, as will be understood.

The reference numerals 11 designate angle iron bars, four of such bars being provided, the same being secured by rivets or otherwise to the sides of the iron ends 9 of the bucket, as will be understood from Fig. 3, and to which angle iron corners the ends of the sides 12 of the bucket are secured, as will also be understood from Fig. 3, these sides being preferably made up of a plurality of boards, as shown in Figs. 4 and 5. One or more of the upper boards are preferably easily removable in order to vary the height of the side of the bucket so that it may be readily adapted for use with wagons having their bottoms different heights from the ground.

The side of the bucket body can be placed under the rear end of the wagon body from which the grain or other material is to be unloaded into the bucket. I preferably provide two pieces of angle iron 38 at thetops of the sides for protecting the edges of the top side boards, as best shown in Fig. 1.

The sides and ends above referred to constitute an open-bottom structure or, body portion, rectangular in form, and supported through the vertical bars 8 and transverse bars 7 andcapable of being lifted thereby, and the open bottom of this bucket body is closed by two swinging bottom sections or doors 13, the inner edges of which overlap when the bottom of the bucket is closed, as shown in Figs. land 3, and which doors are so supported from the body of the bucket that in opening they move for the most part in a lateral direction, see Fig. 4:, the vertical movement of the meetingedges of the doors being comparatively slight.

The doors or bottoms 13 are preferably formed of sheet metal and are provided with upwardly extending flanges 14 at their sides and back which inclose the lower edge of the bucket body when the doors are in their closed position, as shown in Fig. 1. The doors 13 are pivotally supported by means of bars 15, 16, a pair of bars being provided at each end of each of the swinging doors 13. The upper ends of these bars are pivotally supported on the body of the bucket adjacent the ends thereof, as shown at 1'7, suitable brackets 18 being provided for the upper ends of the pivotal supports, while the lower ends of said bars are bolted or riveted to the doors 13 at points 19 adjacent the opposite ends thereof. It, therefore, follows, because of the fact that the pivots 17 about which the doors swing are located some distance up from the lower edge of the bucket body and adjacent the ends thereof, that a movement of the doors in opening is for the most part lateral with reference to the body of the bucket and that the vertical movement of the doors is comparatively slight even at the free meeting edges thereof, at which point the vertical movement is the greatest. i

The reference numeral, 20 designates two gates located one at each side of the bucket, said gates being secured to one of the swinging doors or bottoms 13 so as to be carried thereby, by means ofrivets 21. The gates 20 partake of the swinging movement of the door to which they are secured, as will be understood from Figs. 1 and f, and as the doors swing into their open position, drop below the lower edge of the bucket, and serve to guide the'material as it passes from the bucket and to prevent the material from escaping sidewise, as will be understood.

The reference numeral 22 designates a retarding bar shown as angular in form and extending from side to side of the bucket, the ends of which are supported in an adjustable manner from the sides of the bucket, as will be understood from Fig. 4, wherein a plurality of holes 23 are shown as provided in one of the sides through various of which holes the bolts 24: may be passed, which bolts support the retarding bar through right angle brackets, 25. The purpose of this retarding bar is to retard the fiow'of material from the bucket when the doors are in their open position, and, in order to retard the flow of material to a still greater extent, which is sometimes desirable in dealing with fine material such as grain,

shelled corn, etc, I contemplate using retarding wings 26, four of such wings being shown. The wings 26 are pivotally supported from the retarding bar 22 so that when the doors 1?) are in their closed position, the wings may swing up into the position illustrated in dotted lines, Fig. 4, in

which case their free edges rest upon the doors 13. When the doors are open, theretarding wings swing into the lowermost position in which they are illustrated in full lines, in which case their lower edges occupy positions close to the upper surface of the doors 13. The retarding wings are supported from the retarding bar by means of angular extensions 27 provided at the upper ends of bars 28 secured to the retarding wings, and which extensions extend through openings 29 provided in the retarding bar 22, as'shown in Fig. 1. This construction, it will be appreciated, permits the retarding wings to fold when the doors are closed and provides a stop for limiting the downward movement of the wings as the free end of the bent portion 27 contacts with the inner surface of the angular retarding bar 22. It will be seen that these wings may be removed entirely from the bar by swinging them upward and withdrawing the angular extensions 27 through the openings 29. The purpose of the retarding bar and wings, as explained, is to retard the flow of material from the bucket, the degree of retardation being variable by adjusting the retarding bar and by using therewith retarding wings, as many as may be found desirable. In cases where it is not deemed necessary to retard the flow of material from the bucket, the entire retardingmechanism may be removed as it is secured in place, as above explained, in such a way as to be easily detachable and removable from the bucket body.

The inner or meeting edges of the doors 13 are supported and the'doors held in their closed position by means of centrally located bars 30, the lower ends of which are pivotally connected with the doors through brackets 31 and the upper ends of which bars are pivotally connected with a vertically movable cross head 32, which cross head is adjustably secured to a trip bolt 33 having a head 34, which head is engaged by a trip lever 35 when the doors are closed,

The cross head 32 has been referred to as adjustable, it being obvious that by loosening the screws 36 carried by the cross head, the cross head may be moved up and down upon the trip bolt 33 in order to so adjust the parts that the doors will be closed properly against the lower edge of the bucket when the head 34 is engaged by the latch 35. The opening in the cross head through which the trip bolt 33 passes is enlarged 'at its ends and contracted. to contact with the trip bolt intermediate its ends at 37, see

Fig. 4, from which it will be obvious that the screws 36 may be manipulated in such a way as to tip the cross head with reference to the trip bolt. The purpose of this feature is to permit the doors to be so adjusted that they will close close against the lower edge of the bucket body, this being accomplished by adjusting the cross head vertically, and furthermore to permit of adjustment so that the overlapping edges of the doors will properly contact with one another, this being accomplished by tipping the cross head, if necessary, upon the bolt by means of the screws 36 after its vertical position is properly determined, such tipping motion serving to move the overlapping edges of the doors toward or from one another, as will be appreciated.

The reference numeral 39 designates a guide and stop member through which the lower end of the trip bolt 33 extends, the ends of which stop member are supported by means of bars 40, the upper ends of which are supported from the cross bars 7, the connection between the ends of the stop member 39 and the bars 40 being adjustable in order that the vertical position of the stop member may be varied, this adjustment being secured by means of a plurality of holes 41 provided in the supports 40 through any of which holes the bolts which secure the guide 39 to the supports may pass.

A spring 42 surrounds the trip bolt 33 and is interposed between the cross head 32 and the guide 39 so that as said cross head moves downward after the trip bolt has been released by the latch 35, its movement is cushioned through the spring referred to. The purpose of making the guide 39 adjustable is to provide for varying the opening movement of the doors 13, as it is obvious that the lower the position of said guide, the

greater will be the opening movement of the doors in question.

The reference numeral 43 designates a swivel sleeve made in two parts and held in position between the transverse bars 7 by means of bolts 44, and 45 designatesa swivel through which the bucket is lifted and which swivel is rotatable within the swivel sleeve 43 above referred to, the said swivel having a longitudinal opening 46 into which the upper end of the trip bolt 33 hereinbefore referred to extends and by which the head of said bolt is guided. The swivel in question is provided with a collar 47 which contacts with the under side of the swivel sleeve 43, and which collar is provided with one or more projections 48, which obviously provided in the swivel sleeve for the purpose of receiving the same. It follows, therefore, from this construction that when the latch 35 is in the disengaging position shown in Fig. 4, the swivel may be moved down within its sleeve to bringthe projection or lug 48 out of engagement with the recess in which it rests, after which the swivel can be rotated and the projection in question brought into position to engage another recess, the purpose of which is to per mit the bucket to be hoisted and advanced in four different angular positions with reference to the swivel, the angular position of which remains constant, so that either side or either end of the bucket may be made the advancing portion as the bucket moves along the track provided for it in the building in which the materialbeing transported is to be stored.

The swivel 45 and bucket are lifted through a pulley 50 by means of a lifting rope 51. The pulley is supported from the swivel through straps 52 and in such a way that the axis of the pulley is located slightly to the right (referring to Fig. 4) of a ver 1;.

tical line passing through the axis of the opening 46.

53 designates a balance rope, the lower end of which is secured in an opening provided in a lug 54, and which opening is to the left of the axis of the opening 46 in the swivel. This balance rope is provided with a counterbalance 55, see Fig. 2, and the fact that the axis of the pulley is to one side of the axis of the opening 46, and that the v5 1- strain due to the counterbalance acting through the balance rope 53 acts upon the opposite side of said axis, tends to keep the swivel in a single plane, that is. to prevent the swivel from rotating about a vertical 1 axis and insures that the trip lever 35 will move in a straight line during the horizontal travel of the bucket, as distinguished from perhaps movlng from side to side,

which is a feature ofimportance, as in de vices of the kind to which my invention relates the trip lever is often operated by a fixed stop which the lever might miss if the swivel should rotate as the bucket travels horizontally. Referring still to Fig. 2, my 1 stored, although the track and carrier form no part of my present invention. lVhile, as stated above, the trip lever 35 may be operated by a fixed stop, it may also, and in the drawings in fact is shown as being operated by 'means of a rope 58, and upon being operated, the doors 13 open and the contents of the bucket are discharged as above explained.

The doors 13 are preferably provided with stiffening bars 59 located adjacent their i.

meeting edges so as to keep the bottoms of the doors from sagging, they being commcnly made from comparatively thin sheet metal.

While I.illustrate and describe herein a mechanism carrying out the inventive idea in what I believe to be the most suitable form, it is to be understood that the several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereafter claimed.
