LOADING MACHINE.

This invention relates to loading devices lIld pertains particularly to a device for loading grain or like material, from a bin to awagon or from a wagon to a bin.

The primary object of this invention is the provision, in a manner as hereinafter set forth, of an easily transported and easily handled and shifted loading device which may be employed for removing grain. or other small material from a wagon and conveying it to a storage bin, or if desired for removing material from a storage bin. to a wagon. Another object of the invention is the provision, in a manner as hereinafter set forth, of a loading device of the character above described, which can be easily and quickly raised or lowered or swung from one osition to another for the positioning ofthe loader in a desired location.

A further and final object of the inven tion is the provision, in a manner as hereinafter set forth, of a loading device whichshallbe' of simple but strong and durable construction, easy .to operate, and comparat vely inexpenslve to manufacture and set up. r The invention will be best understood from a consideration of the following detailed description taken in connectionwith the accompanying drawing formlng a part .of thisspecification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawings but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the a portion of the structure, the same being.

partly in section.

Referring now to the drawings in detail wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates a platform which comprises the side and the rails 2 and the floor or bottom 3. This platform is here showman supported upon legs 4 but, it in to Application filed August 5, 1926. Serial No. 127,339.

be understood that the same maybe sup ported in any desired manner such as upon a truck body. to enable its easy transportation from point to point.

To one end of the platform 1 there is fixed in upright position a pair of beams or standards 5, arranged one upon each side of the platform.

Secured across each standard 5 adjacent the upperend thereof, is a beam member indicated generally by the numeral 6. As shown this beam is secured intermediate its end to the adjacent standard and the inner portion of the beam extends downwardly and is secured to a side rail2 of the platform 1, as indicated at 7, This portion constitutes a brace for the standard 5. The forward end of each beam, extends forwardly and upwardly from the adjacent standard 5 setting up the extended supporting arm 8, the free end of which projects a substantial distance above and forwardly .ofthe attached standard 5. A connecting member 9 extends across and connects the free ends of the supporting arm 8, thus setting up a crane-like structure at the forward end of the platform.

. Extending through one of the standards 5 and through the beam 6 which is secured H thereto, is an elongated sleeve 10.11pon the outer end of which a collar 11 is formed which collar bears against the outer face of the beam 6. A similar relatively short sleeve .12extends through the other oneof the standards 5 and through the attached beam 6, and this sleeve 12 also has a collar 13 upon the outer end which bears against the outer face of the standard 6, as shown in Figure 3.

Extending through the sleeves 10 and 12 and extending across the frame 1, is a shaft 14 which turns freely in both of the sleeves 10 and 12. j i

Adjacent the outer end of the sleeve 10 and mounted upon the shaft 14, is a pulley 15. This pulley revolves freely upon the shaft 14: but is fixed to the sleeve 10 to cause the sleeve to revolve therewith.

Mounted upon the sleeve .10 adjacent the inner end thereof, is a pulley 16. The operation of this pulley will be described further. Secured aboutthe central portion of the shaft 14 is a relatively short tubular shaft 17 and mounted upon and secured to this tubularshaft 17 is a reel 18. U 7 Upon the other endof the shaft 14: against" ill the outer side of the flange in the sleeve 12, is mounted a ratchet wheel 19which ratchet wheel is controlled by a pawl 20 pivotally secured to the adjacent upright 5. crank 21 is mounted upon this end of the shaft 14 and by means of this the shaft 14* and reel 18 can be revolved.

Carried upon the tubular shaft 17 adjacent each end thereof is a forwardly and downwardly extending two-part arm indicated generally by the numeral 22. Each of these two part arms comprises an inner portion 23 and an outer portion 24, having their adjacent ends in overlapping relation and secured by the bolts 25 in the manner shown. The tubular shaft 17 which extends through the inner end of each of the inner portions 23 of the arm is adapted to freely revolve so that the sections of the arm will not turn with the shaft.

Mounted between the extended ends'of the arms 22, is an endless conveyor casing indicated' generally by the numeral 26, this casing having a relatively long portion 27 and a short portion 28. The portions 27 and 28 are in obtuse angled relation and the casing is open upon the upper side as clearly shown in Figure 1. The forward ends of the arms 22 are pivotally secured as at 29', one to each side wall of the conveyor casing, with ,the long portion 27 normally in upwardly extending position and the short portion 28 in substantially vertical position as shown.

At the forward end of the long portion27 and at the lower end of the short portion 28, there is fitted between the side walls of the casing a shaft 3'0'upon which shaft, within the casing, is mounted a' pair of sprocket wheels 31. At the point of joinder between the sections 27 and 28, adjacent the top of the casing there extends between the si'de walls a shaft 32, one end of which extends through and a substantial distance beyond one side wall of the casing and has mounted upon the outer end thereof the pulley 33. Within the casing this shaft also carries a pair of sprocket wheels indicated in Figure 1 by the numeral 34. The floor of the casing 26 is rounded at the point 35, for the purose hereinafter set forth.

Extending over and connecting the sprocket wheels 31 and 34 upon each side of the endless conveyor casing, is an endless chain 36 and secured to this chain is a plurality of spaced cups or buckets 37 which, as will be readily understood, move with the endless chain through the casing, those buckets which pass over the bottom of the casing have close contact with the bottom and therefore any material contained therein will be prevented from spilling, as the bottom of the casing covers the opened top of each bucket passing thereover. The rounded portion of the casing body allows the buckets to turn smoothly without support.

The pulleys 16 and 33 are connected by the belt- 38 while the pulley 15 is connected by he belt 39 with the pulley 40 carried upon the shaft 41 of a power engine indicated conventionally by the numeral 42, and the endless conveyor is thus operated within the casing 30 through this power means.

overlying the shaft 14 and journalled at each end in one of the standards 5, is a second shaft 43, which shaft carries at its central portion the reel 44, secured thereto. One end of the shaft 43 extends beyond the standard 5 and carries thereon a ratchet wheel 45 and adjacent the ratchet wheel a crank 46 by means of which the shaft is turned. A'dog 47 is pivoted to the standard 5 and acts to control the ratchet wheel 45 in the usual manner.

Each of the reels 18 and 44 has wound thereabout a cable 48 and each of these cables runs forwardly to and over a pulley 49 carried upon the underside and at the central portion of the cross member 9 at the outer ends of the arms 8. The cable 48 from the reel 18 has connection with each side of the conveyor housing 26 adjacent the inner end thereof as indicated at 50 while the cable which is wound about and fed from the reel 48, has connection at 51 with each side wall of the conveyor housing 26 adjacent the free outer end thereof, as shown in Figure 1.

From the foregoing description it will be readily seen that when it is desired to shift the conveyor the manipulation of the crank handles 21 and 46 will raise or lower, as desired, the inner or outer end of the long portion 27 of the conveyor, the inner end of the conveyor swinging in an arc controlled by the arms 22.

As is shown in Figure 1, a wagon indicated in dotted lines by the numeral 52 may be run beneath the open end of the short portion 28 of the conveyor and by the operation of the cables 48 the end may be lowered into the wagon while the other end of the conveyor discharges the grain taken from the wagon, into an adjacent bin. By reversing the power mechanism 42 the travel of the conveyor will also bereversed and the same may be employed for removing material from a bin and discharging the same into a wagon.

hen it is desired to shift the platform and other structure carried thereby, the conveyor can be so swung as to bring the portion 28 inwardly upon the platform so that any strains thrown upon the supporting' means for the conveyor, incidental to the moving of the same, will not result in the damage of the conveyor supporting means. By reason of making the arms 22 in two parts, each including the'part 23 and the part 24, it can readily be seen that the conveyor frame can be properly adjusted and on such adjustment the pivotal connection between these parts 23 and 24 is made rigid by the bolt and nut carried by the latter. By making the bolt and nut fast to secure the parts of the arms 22 the same cannot buckle or have toggle action.

Having thus described my invention what I claim is In combination, an elevated platform, uprights secured to one end thereof, upper and lower shafts jouI'naled in said uprights, an inclined suspension frame having its lower end connected to said platform, connected intermediate its ends to said uprights and projecting outwardly from these latter, adjustable, hinged members extended from said lowermost shaft, means for latching the hinged members in adjusted position, a conveyor mechanism pivotally connected intermediate its ends to the outer ends of said members, adjustable suspension cables connected with the conveyor mechanism at two points beyond its pivotal connection with said members, said cables winding on and off said shafts, a pawl and ratchet mechanism associated with each shaft, and conveyor mechanism operating means supported by the platform and operatively connected with such mechanism.

In testimony whereof, I affix my signature hereto.

WESLEY A. HULA.
