DISTRIBUTING ELEVATOR.

Application filed May 26, 1920. Serial No. 384,358.

To all whom it may concern-.-

Be it known that I, WALTER J. BLnNKo, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Distributing Elevators; and I do hereby declare the fol lowing to be a full, clear, and exact description thereof,

My invention relates to elevators for use in loading apparatus and the like. and it has special reference to elevators of the type which are adapted to lift material from a common source and deliver it into any one of a number of receptacles, and which for this purpose are provided with a swivel mounting around which the elevator may be turned in the arc of a circle.

The object of my invention is to provide an improved swivel mounting for elevators of the above-indicated character and, in particular, to provide a mounting which shall be simple and rugged in construction and which shall serve to support the elevator from a point above its lower end, for a purpose more fully described below.

In the accompanying drawing, Fig. 1 is a side view partly in elevation and partly in section of an elevator constructed in accordance with my invention; Fig. 2 is an enlarged detail showing in vertical section the swivel mounting which I prefer to employ, and Fig. 8 is a plan view of the construction shown on Fig. 1.

In the drawing, the numeral 2 designates a pit which is below the ground level 3 and in which is disposed the lower end of an endless bucket conveyer t of any suitable construction. The conveyer l is carried upon a supporting frame comprising inclined supporting members 5, vertical braces 9 and a truck structure 20. The inclined members 5 also carry a hopper 6 that is adapted to receive material from a feeder 7, the specific construction of which forms no part of my present invention, and which is located beneath tracks 8. The braces 9 carry at their lower ends wheels 10 that travel on a circular track 12 centered at 16.

Extending on either side of the feeder 7 are two channel beams or supports 13 which are bolted to the foundation 14 and which converge at their inner ends 15 to support the swivel mounting for the elevator, which is designated generally by the numeral 16 and is shown in detail in Fig. 2. This mounting consists of a plate 17 having a spherically curved depression 18 on which rests a swivel member 19 carried on the underside of the truck structure 20 the arms of which extend horizontally between the swivel mounting and the lower ends of the supporting braces 9. The spherical bearing ensures freedom of motion if the track 12 is irregular. The plate 17 and the swivel member 19 are secured together by means of a loose-fitting hollow bolt 21 through which may extend the lead-wires for the driving motor of the elevator. Theconveyor frame 5 is supported by the braces 9 and by a transverse bar 22 which extends across the truck frame 20.

When the above-described elevator is in operation, the material discharged into the hopper 6 by the feeder 7 is carried upward by the elevator buckets and discharged into one of the bins or other receptacles that may be arranged adjacent to the curved track 12. By reason of the fact that the swivel mounting is located above the lower end of the conveyor, it will be apparent that the pit 2 need only be deep enough to provide clearance for the elevator buckets. This is a special advantage owing to the fact that no obstruction whatever exists at the lower end of the elevator, as compared with distributing elevators in which the conveyer-supporting frame is mounted on a swivel in the pit and beneath the lower end of the elevator. Also the mounting cannot freeze in winter.

Vhile I have shown and described herein a preferred form for employing my invention, it is to be understood that various changes may be made in the form and ar-' rangement of parts, and I therefore desire that no limitations be imposed upon my invention except such as are indicated in the appended claims.

YVhat I claim is:

1. A distributor elevator comprising a conveyer-supporting frame mounted to swing pivotally, a conveyer carried by said frame, a feeder disposed adjacent to said frame, and a pivot bearing for the said frame disposed above the lower end of said conveyer and on the side of said conveyer toward said feeder.

2. A distributing elevator comprising a c-onveyer-supporting frame mounted toswing pivotally, a conveyer carried by said frame, a material-receiving hoppercarried by the said frame and a pivot "bearing for the said frame disposed above the lower end of said conveyor and on the same side of said conveyer as said hopper;

3. A distributing elevator comprising a conveyer-supporting frame mounted to swing pivotally, a conveyer carried by said frame, a curved track formingasupport for the outer end of the said frame, and a pivot bearing for the said frame disposed above the lower end of said conveyer and on the opposite side of said frame from said track.

4. A distributing elevator comprising a ronveyer-supporting frame mounted to swing pivot-ally, a conveyer carried by said frame, a hopper carried by the said frame, a curved track forming a support for the outer end of the said frame and a pivot bearing for the said frame disposed above the lower end of said conveyer and on the opposite side of said frame from said track.

5. A distributing elevator comprising a frame having inclined supporting members, an endless conveyer carried by said supporting members, and adapted to be charged from the upper side thereof, and a pivot position for all angular positions of thesaid frame.

7. A distributing elevator comprising two stationary supports, a pivot bearing carried by said supports near the junction thereof,

a curved track, an inclined conveyer-supporting frame supported partly by saidv bearing and partly by said track, an endless conveyer carried by said frame, and a hopper carried by said frame beneath the said bearing.

In testimony whereof I, the said lVAI/rnr. J, Br-nNKo, have hereunto set my hand.
