SPECIFICATION forming part of Letters Patent No. 769,947', dated September 13, 1904;.

Application tiled May 18, 1903.

To all wiz/011m it may concern,.-

Be it known that I, EMIL M. KRAMER, acitizen of the United States, residing at Cissnapark, in the county of Iroquois and State of Illinois, have invented certain new and useful Improvements in Grain-Conveyers; and I do hereby declare that the following isa full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to conveyers for handling grain and other substances, such as ores and the like.

The primary object of my invention is to provide means for releasing a track-carried conveyer for permitting it to automatically changeV its position on its track, so that grain may be delivered into different receptacles.

Another object is to provide an automatically-adjustable conveyer for depositing grain into a series of bins or receivers.

i Still another object is to provide a peculiar mechanism for accomplishing the above purposes.

In the drawings herewith presented, Figure 1 is a plan view of a portion of my conveyer, showing the gearing for operating it.

Fig. 2 is a side elevation of a portion of the conveyer and means for locking 1t in a desired position. Fig. 3 1s a side elevation of the conveyer, showing the track on which it is carried. Fig. 4 is a. perspective view of one end of the conveyer, showiig a swiveled delivery-spout therefor. Fig. 5 is a perspective view of a portion of the conveyer and its track, showing the locking means above mentioned. f

A indicates the conveyer, on which are carrying-wheels B, adapted to run upon the track C, the'latter being supported from the roof of the granary or other building containing bins or receivers to be filled with grain or other material, such as has been described and shown in a previous application filed by me on the 22d day of December, 1902, and bearing the serial number 136,286.

The driving mechanism herein shown and described is also shown in the-above application, but the novel features of this present Serial No. 157,742. (No model.)

is driven by means of three rollers G H I,

said beit passing over the roller G, under roller H, and over roller I, as shown in Fig. 3. Thescfare journaled on top of a frame J, located on the top of the bins, and a supplementary frame K is located adjacentpto the frame J- and carries a shaft L, parallel with the conveyer. L, loose on said shaft and meshing with a similar gear M, secured on the shaft of the roller H. Also upon the shaft L is a shiftingslecve N, having a projection O at each end to enter depressions at P in the hubs of the loose gears L'.- Said sleeve is adapted to revolve with the shaft, this being accomplished by a key Q, secured in the shaft and upon which the sleeve slides. On the shaft L is a sprocket-wheel it for transmitting motion to said shaft from any source of power. I provide a forked lever S, which is pivoted on the frame K and is used to shift the sleeve N from one gear to the other. It will be seen that motion imparted to the shaft L in one direction will transmit motion to the roller H in one direction or the other, depending' upon which gear L is engaged by the shifting-sleeve N. lhis has been described in the application above referred to and will need no further attention here.

I now desire to direct attention to the means for locking the conveyor in any desired position upon the track C described. At one side'V On said shaft are two beveled gears l spring-bolt is provided with an eye 3 at its lower end, with which engages a U-shaped arm or crank 4L, having its bearing in a bracket 5, secured to the conveyer. A rope is attached to said arm A, by which the spring-bolt may be withdrawn from the socket W. Said arm or crank l is merely used to carry the pullcord 6, used therewith, out beyond the frame J, as indicated in Fig. 1, so that the bolt may be operated without interference by said frame. Evidently other means may be employed to withdraw the spring-bolt, or the frame J may be arranged in such a way that the bracket 5 and said arm 4 may be dispensed with. It is necessary when the bins or re ceivers are of large size and cover considerablel territory to have the distributing-con- -veyer therefor shift on its track in both directions, so that any bin may be reached for deposit of grain thereinto. The rollers G H I, being driven from the shaft L through the gears described, will drive the belt E in one direction or the other, so that the grain deposited on said belt from the elevator (not shown) will Abe delivered from one end or the other of the conveyer.

Wvhen it is desired to shift the conveyer while the rollers are moving, it is only necessary to pull down the rope 6 and withdraw the spring-bolt from engagement with the track, and the conveyer will be moved by the belt E in the direction in which the upper stretch of said belt is traveling, as will be understood. By holding said bolt down the conveyer will move to the desired position, where it may be arrested from further progress by permitting the bolt to contact with the track, where it will enter the first socket W that passes above it. If it is desired to shift the conveyer in the other direction, a simple reversal of the movement of the belt through the medium of the shifting-sleeve N will aecomplish it.

On each end of the conveyer is a swiveled spout A,slotted at 7. A pin 8 is passed through the slot and secured in the fixed portion of the conveyer and holds the said spout in place and allows said spout to be swung in any direction, so that the grain may be deposited at either side of the conveyer into one or the other of the bins T, as shown in Fig. l.

for locking the conveyer at the desired place eser Avaineetti after it has been moved by the belt by the means I employ, and

Therefore l claim-Vm l. 'Ihe combination of the horizon tal adj ustable conveyer A, the track l at the sides of the conveyer, the wheels B on the conveyor for ruiming upon the track, the rollers F at each end of the conveyer, the belt It running on the same, the rollers Gr, H, I journaled beneath the conveyer through which the belt passes and driven therefrom, the vertical spring-bolt V on the conveyor for engaging the track, the pull-cord for withdrawing the sin'ing-lgiolt from engagement with thc track and being' operated from below, the rollers shifting the conveyer by means of the belt IC along the track when the spring-bolt is withdrawn from the track said eonveyer boing free to move until the bolt is again in engagement with the track as set forth.

2. The combination of the conveyer A, the track C, the wheels B on thc conveyor for traversing the track, the rollers F in the con veyer, the belt E thereon, the rollers G, I-I, I beneath the conveyer, the belt running over one, ben neath the second and over the third substantially as shown and for thepurposes set forth, the bracket U secured to the conveyer, the spring-bolt V carried therein, the spring 2 for holding the bolt in engagement with the track, there being sockets in the under side of the track into which said bolt is adapted to seat and a pull-cord 6 for withdrawing the bolt to permit the belt and d riving-rollers to shift the conveyer on its track for the purposes set forth.

3. The combination of the conveyor A, wheels B thereon, the track C, rollers F in the conveyer, the belt E thereon, rollers H, l, for driving the belt, the bracket U secured to the conveyer, the spring-bolt V carried thoreby, the spring 2 for normally keeping the bolt in engagement with the track, there boing sockets in the track foi` receiving the bolt, the arm 4 in engagement with the bolt V, the bracket 5 for carrying the arm L and the pullcord 6 attached to the arm for \\'ithdrawing the spring-bolt substantially as set forth and described.

In testimony whereof I aliix my signature in presence of two witnesses.

EMIL M. KRAMER.
