ELEVATING-MACHINE.

Specification of Letters Patent.

Patented May 315, 1917.

Application filed. December 26, 1912. Serial No. 738,679.

To 6422 whom it may concern:

Be it known that I, CHARLES W. HADLEY, a citizen of the United States, residing at Ogden, in the county of Weber and State oi" Utah, have invented a new and useful Elevating-Machine, of which the following is a specification.

My invention is an improvement in elevators for grain and other commodities, whereby the contents of the buckets are forcibly ejected, and admits of running of the machine at any speed, without danger of cupping the contents down.

While the above is the principal object of my invention, I have also provided means whereby the device can be quickly transformed into an elevator of the ordinary type.

The principle and operation of my machine is plainly illustrated by the accompanying drawings, in which Figure 1 is a vertical section of the entire machine; Fig. 52, is a vertical section of the same, showing the transformation into the ordinary elevator. While pulleys and belts and sprocket wheels and chains can either be used with my machine and any commodity be elevated, for my illustration, I have used pulleys, and grain to elevate.

In Fig. l, A is the main pulley and B is an idler pulley, preferably smaller, in front of and near to pulley A. D designates the belt having a plurality of buckets thereon and for the purpose of further description certain of the same are designated by the let ters E, E" and E. G is a tilting bracket, carried by the shaft F and holding the bearings G and G for the pulleys A and B. H is the lower pulley of the elevator and I is a hopper. Suitable supporting means is provided for this device and is designated by the numeral 10, the same having means whereby the pulley H is journaled thereto and also for the journaling of the shaft F that carries the bracket 0. As is shown in Fig. 2, the bracket C is tilted forward to change the machine to a Single pulley elevator, and for accomplishing this purpose I have provided on the shaft F fast thereto, a sprocket wheel J and journaled in the support 10 a sprocket wheel L having a lever or operating handle K thereon. A chain M is trained over these sprocket wheels J and L and movement of one will necessarily impart motion to the other. It is of course obvious that this handle or lever K is within access of the operator so that the machine can be changed to assume the position shown in Figs. 1 or 2 at will.

The pulleys A and B are so proportioned in size and the bracket C so centered on shaft F that the tension of belt D is not altered during the change, which can be made while the machine is in motion.

The operation of the machine is as follows, reference being had to Fig. 1. The buckets E in passing around pulley II are filled with grain and carried over pulleys A and B and the contents deposited as desired. Up to the time at which the bucket E reaches such a position that its center is in the same horizontal plane as the axis of shaft g of pulley A, the bucket and belt have moved at the same speed. In passing around pulley A to position of bucket E, the bucket and contents has moved faster than the belt in proportion as it is more distant from the center of motion. From position of F/ toward pulley B, the bucket again moves at the same speed as the belt, but the grain continues at the greater speed and is beyond the reach of the bucket as it passes around pulley B. This is true without regard to the speed of the machine.

Referring to Fig. 2. In case it is desired to use the machine as the ordinary one pulley elevator, all that is necessary, is to tilt, by lever or otherwise, the bracket C forward, bringing pulley A to the front and dropping pulley B from connection. This can be done while the machine is in motion.

The advantages claimed for my machine over the old style areIn the machines now in use, the contents must be flirted from the buckets, in case of a perpendicular machine. In case of an inclined machine, gravitation added to the speed of the bucket clears the grain from cupping, and in either case the speed must be carefully regulated. In my improved elevator, whether it be perpendicular or inclined, the grain is forcibly ejected from the bucket without regard to speed. The change to the ordinary machine can be made by a lever.

I am aware that there are elevators which have pulleys in advance of the main pulley which carry the chain and buckets to varying distances but in all such cases, the contents of the buckets are either dropped between the pulleys or are carried in the buckets over the second pulley, while in my machine, the pulleys are nearly in contact and the buckets have no connection with, nor control over the contents after leaving the main pulley.

I claim: a 1. In elevating machines, the eombinatio of a multiple-run conveyer, and means for increasing or diminishing the number of runs of the eonveyer, optionally.

2. In elevating machines, the combination of a multiple-run conveyer, and means for increasing or diminishing the number of runs of the conveyor, optionally, during the operation of the conveyer.

3. In elevating machines, the combination of a lower pulley, two upper pulleys mount ed in spaced relation, a belt passed about all of said pulleys, and means for moving one of said upper pulleys out of engagement With said belt and for simultaneously raising the other said pulley, whereby the conveyer can be converted from a three-run into a two-run conveyer, optionally, and said belt maintained under constant tension.

l. in elevating machines, the combination of a pulley, a tiltably journaled bracket, two pulleys carried by said bracket and mounted in spaced relation, a belt passed about all of said pulleys, the pulleys carried by said bracket being inside of the runs of the belt, and means for tilting said bracket.

5. In elevating machines, the combination of a pulley, a tiltably journaled bracket, two pulleys carried by said bracket and mounted in spaced relation and closely adjacent each other, a belt passed about all of said pulleys, the pulleys carried by said bracket being inside of the runs of said belt, and means for tilting the bracket.

6. In elevating machines, a conveyor, and

with said first named axle, a bracket journaled on said last mentioned axle and carrying idler pulleys, a belt running. over all of said pulleys and provided with conveyer buckets, and means for shifting said bracket to throw one of said idler pulleys out of engagement with said belt.
