GRAIN-ELEVATOR.

Specification of Letters Patent.

Patented Nov. 1915.

Application fi1ed February 10, 1913. Serial No. 747,491.

To aZZ whom it may concern:

Be it known that we, ALoNzo T. ADAMs and JosErH DAIN, citizens of the United States, residing at Moline,'in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Grain-Elevators, of which the following is a specification, reference being had therein to the accompanying drawing.

' Cur invention relates to that class of mechanical structures comprising portable wagon-clumps and elevators employed toremove a load from a wagon and deposit it in some other receptacle, and it consists of a novel and economical arrangement and operation of the various parts as will be more clearly described and claimed hereinafter.

Referring to the drawings in which similar numerals indicate identical partsFigure 1 is a perspective view. Fig. 2 is a plan of the receiver and part of the elevator. Fig. 3 is a side elevation of Fig. 2, and Fig. 4 is a detail section.

In a structure of this description, power is conveyed to the dumping and elevating mechanism through a power-shaft 1, any suitable power being employed. The dumping apparatus is of an ordinary type, consisting of a frame 2, from which is suspended a vertically movable bar 3 having suspended therefromloops 4 adapted to engage with the front end of a wagonto raise it so that the load will be deposited in a receiver 5 at the foot of an elevator 6, and forming part thereof. The bar 3 is raised or lowered by means of a cable 7 on a drum 8, the latter operated from the power-shaftl by means of intervening gearing in a manner well known in the art.

The receiver 5 is located so that anywagon being dumped will deposit the'load therein, the latter falling upon a conveyer 9, atthe bottom of the receiver5, moving toward the elevator 6 and carrying thereto the material received from the wagon. The con veyer 9 consists of sprocket chains 10 and 11 engaging with sprockets 12, and having secured to them at suitable intervals blades 14. The sprockets 12 are idlers and revolve on a shaft having bearings in the outer end which engages with a sprocket 20 secured on a tubular shaft 21 and receiving motion from the power-shaft 1 as will be explained. The tubular shaft 21 revolves in roller bearings 22 and 23 forming part of brackets 24 and 25 secured to the sides of the elevator box 26. V

The power-shaft 1 is preferably composed of three sections, a, Z), and c, the central section I) is journaled in the tubular shaft 21, and has upon one end a member 27 of a clutch which is, free to move longitudinally I to which is pivoted a vertical lever 32 which engages with the ring 30, so that a movement of the lever 32 toward the receiver 5 will engage the clutch member 27 with a clutch member 33 on the face of the sprocket 20 to operate the conveyer 10 in the receiver 5 through the chain 19 and sprocket 18, and

at the same time imparting motion to the conveyer-M in the box 26 forming the elevator, the'latter conveyer being similar in construction to the conveyer 9, and carried on sprockets 35 and 36 secured to the tubular shaft 21 and revolving therewith.

The power-shaft section 0 is coupled to a clutch member 37' which is loosely mounted on the power-shaft section b, and power to operate the dumping mechanism through the section a is conveyed to the latter by moving the lever 32 away from the receiver 5-until the clutch members 27 and 37 are in engagement. Normally the clutch member 27 is out of engagement withthe members 33 and 37 as shown in Fig.4, so that the conveying and elevating mechanism can be operated independently of the dumping mechanism, or both may remain idle while the sections a and b of the power-shaft 1 are revolving.

On each side of the receiver 5 is hinged a door 38 and 39 and adapted to fall into the position shown in dotted lines in Fig. 4 forming a hopper when the load from a wagon is dumped into the receiver, the limit 1 of the door movement being regulated by suitable hook arms attached thereto and adapted to catch on the receiver in a well known manner.

To automatically start the operation of the conveying mechanism a rod 40 is rockable in bearings'on a side of the receiver 5, one end ll of said rod being bent, as shown in Fig. 3, to present a greater bearing surface against the door 38; theother end of the rod &0 is bent outwardly and upwardly forming a crank arm 42 in which is a vertical slot 43 connected tothe crank-pin 42 in the slot 43 is a rod 44: whichprojects through the tubular shaft 15 and is attached to the lever 32; a coiled spring 45 on the rod 4%, and interposed between the lever 32 and sprocket 18, tends to keep the door 38 in a closed position; it will be readily apparent that the pressure of the material dumped into the receiver will cause the door 38 to drop, rocking the rod 40 and actuating the rod 44 to move the lever 8:2 toward the receiver 5 and engaging the clutch members 27 and 33 so'that revolution of the powershaft sections a; and b will impart motion to the conveying and elevating mechanism; when the pressure on the door 38 is'removed the expansion of the spring 45 will close said door by rocking the rod 40 to its normal position, and at the same time the clutch members 27 and33 will be disengaged and the conveying and elevating mechanism will stop.

What we claim is 1. The combination with an elevator, of power actuated means for operating said elevator but normally out of engagement therewith, a lever adapted to be manually operated to connect the elevator with the power actuating means, and means to auto matically operate said lever to connect the elevator with the power actuating means.

2. The combination with an elevator, of power actuated means for operating said elevator but normally. out of engagement therewith, a receiver forming part of the elevator-and having a door thereon adapted to swing outwardly, and means operated by the outward swing of said door to connect said elevator with said power actuating means.

3. The combination with an elevator, of power actuated means for operating said elevator but normally out of engagement therewith, a receiver forming part of the elevator and having a door thereon adapted to swing outwardly, a lever operable to 0011- nect the elevator with the power actuating means, and a rod engaging with said door and connected to said lever to actuate the latter by the downward swing of the door to connect said elevator with the power actuating means. v

4. The combination with an elevator, of power actuated means for operating said elevator but normally out of engagement therewith, a receiver forming part of said elevator and having a door thereon adapted to swing outwardly, a lever operable to connect the elevator with the power actuating means, a rod engaging with said door and extending along the receiver to which it is rock-ably secured, a crank-arm on said rod, a rod extending transversely of said receiver and connected to said crank-arm and said lever to actuate the latter by the downward swing of the door to connect the elevator with the power actuating means.

5. The combination with an elevator, of power actuated means to operate said elevator, comprising a tubular shaft, means connecting said shaft with the elevator, a shaft within the tubular shaft and connected with a source of power, and means automatically operable to connect said shafts for simultaneous movement.

6. The combination with an elevator, of power actuated means to operate said elevator, comprising a tubular shaft connected with the elevator, a shaft within the tubular shaft and connected with a source of power, means manually operable to connect said shafts for simultaneous movement, and means to automatically actuate said manually operable means. v

In testimony whereof we affix our signatures, in presence of two witnesses.
