MANURE-LOADER.

Specification of Letters Patent.

Patented June 2, 1908.

To all whom it may concern:

Be it known that we, JOHN D. RIETVELD, CORNELIUS DIELEMAN, and WIEGERT D. tIETvELD, citizens of the United States, residing at Pella, in the-county of Marion and State of Iowa, have invented a certain new and useful Manure-Loader, of which the following is a specification.

The object of our invention is to provide a manure loader of simple, durable and inexpensive construction in which the receiving and dumping platform may be placed in one position and a number of scraper loads of manure easily and conveniently deposited thereon and then the receiving anddumping platform may be elevated and the load automatically discharged into a Wagon adjacent thereto.

Our invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in Which Figure 1 shows a side elevation of the complete manure loader embodying our invention, the dotted lines show the receiving and dumping platform in position for discharging into a wagon, and ldig. 2 shows a rear elevation of the completemachine embodying our invention.

Referring to the accompanying drawings, the base of the machine is composed of four runners indicated by the numeral 10. Secured to the rear ends of these runners are the uprights 11 connected at their upper and lower ends by the braces 12. Secured to the forward ends of the runners are the short uprights 13, said forward ends of the runners being connected by a cross brace 14. The rear uprights 11 are supported in their upright position by the braces 15 and the short uprights 13 are supported by the braces 16, thus forming a light yet strong frame for the device. Mounted in the forward uprights 13 is a shaft 17 on which a number of rollers 18 are mounted. At the top of the rear uprights 11 is a cross piece 18 having at each end two pulleys 19 and 20. At the bottom of two of the uprights 11 are the direction pulleys 21.

The manure receiving and dumping platform is supported upon arms 22 having their rear ends pivoted at 23 to the outeruprights 11, said arms projecting to a position beyond the front of the frame where they are connected by a cross piece 241. Mounted on this cross piece are two pulleys 25 near each end. On the outer end portions of the arms 22, we have fixed the manure receiving plat form 26. Pivoted to the arms 22 adjacent to the cross piece 24 are the bars 27, to which a dumping platform 28 is fixed having the sides 29. The dumping platform is normally held at an angle slightly greater than a right angle relative to the receiving platform 26 by means of two jointedarms at the ends thereof. Each of said arms comprises a part 30 pivoted to the dumping platform and a part 31 pivoted to the arm 22. These arms are pivotally connected at their central portions by the bolt 32 and the part 31 is provided with an extension 31 to overlap the part 30 and prevent the joint that connects said parts from bending in a direction away from the extension 31, said extension, however, does not prevent said arms from bending at their pivot in a direction toward the receiving platform. Fixed to the ends of the cross piece 12 are two stops 33 in position to be en-. gaged by the parts 31 as the platforms approach their dumping position.

We have also attached to one of the arms 22 a contractible coil spring 33 the other end of which is attached to the central portion of one of the runners 10, said spring being so arranged that it will be under tension 'when the arms 22- are in dumping position and said spring is of such resiliency that when the load has been discharged, the spring will move the arm 22 to which it is attached to a position past a vertical line drawn through the pivotal point of the arm 22, so that the receiving and dumping platform' may then automatically return by gravity to position for receiving a load.

e have provided for elevating the platforms as follows Two ropes or cables are provided, one for each end of the device, said ropes having their ends connected to a swingle-tree 34 to which a draft animal may be attached. One of these ropes 35 is extended first under the pulley 21 at one end of the frame, then over the pulley 19 that is directly above it, then under one of the pulleys 25, then over the pulley 20, then under the other pulley 25 and its end is attached to the part 18. The other rope 36 is arrangedin a similar manner at the other end of the frame. For moving the loader from place to place, -We have provided chains 37 attached to thecentral runners 10 and connected by a ring 38 to which draft animals may be connected. In practical use and assuming the device to be in the position shown in solid lines in Fig. 1, a load may be readily and easily placed upon the receiving of a scraper or in any other way. sufficient load has been placed thereon, a wagon is positioned adjacent to the rear of the frame and the draft animal connected with the ropes 35 and 36 is advanced. By having the ropes passed over the guide rollers l8 and then almost straight downwardly, it is obvious that the outer ends of the arms 22 are given almost a direct upward pull so that less power is required for starting the load, than though the ropes passed direct from the ulleys at the upper rear end of the frame to t e outer ends of the arms 22. Furthermore by the pulley arrangement shown and described, the power applied to the ends of the ropes 35 and 36 is greatly increased as applied to the arms 22. When the arms 22 approach a substantially upright position, the load on the receiving platform 26 is discharged upon the dumping platform 28, which, however, is held in position substantially at right angles to the receiving platform so that the material will be retained in said dumping platform. Immediately after the arms 22 have passed a vertical line, the arms 31 will engage the stops 33 and thus remove the support for the rear end of the dumping platform permitting it to swing to the position shown by dotted lines in Fig. 1, so that its contents may be discharged into the wagon. As soon as the load has been discharged, he spring 33 will return the arms 22 to a position in front of a vertical line and they will descend by gravity to their starting position. By thus providing means for automatically dumping the platform 28, it is not necessary to move the arms 22 much beyond a vertical line so that the machine frame need not be as high nor the arms 22 as long as they would if the dumping platform were fixed in its position relative to the receiving platform.

Having thus described our invention, what we claim and desire to secure by Letters Patent of the United States, therefore 1S- 1. In a manure loader, the combination of a frame, arms pivoted to the frame, a receiving platform fixed to the arms, a dumping platform pivotally connected with the arms adjacent to the receiving platform, jointed braces for the dumping platform, means for jointly elevating the arms and means for breaking the joints of the jointed braces when the platforms approach their dumping positions.
