PNEUMATIC ST-ACKER.

SPECIFICATION forming part of Letters Patent No. 722,369, dated March 10, 1903.

' Application filed April 14, 1902. Serial No. 102,722. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES N. LEONARD, a citizen of the United States, residing at Indianapolis, in the county of Marion and State 5 of Indiana, have invented certain new and useful Improvements in Pneumatic Stackers, of which the following is a specification.

My present invention relates to that class of apparatus which is designed for handling straw and such like material, and embodies a means whereby the material as it is delivered may be automatically distributed over the entire surface of the stack or structure being built and may also, if desired, be so 1 guided as to form aconicalstack or'structure. Generally speaking, said invention consists in securing upon the outer end of the delivery trunk or chute of a pneumatic stacker an inclined and revolving delivery-nozzle and providing suitable mechanism for imparting motion thereto.

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure l is a side elevation of apnenmatic stacker provided with devicesembodying my present invention and mounted upon a threshing-machine or separator ready for use; Fig. 2, a similar view, on a considerably 3o enlarged scale, of the stump or neck of the stacker, together with the turn-table and adjacent portions of the mechanism for manipulating the same; Fig. 3, a top or plan View of substantially the same parts shown in Fig. 5 2; Fig. 4, a side elevation, on an enlarged scale, of the upper or outer portion of the stacker trunk 01' chute carrying the nozzle and operating mechanism, which are the leading features of my present invention; Fig. 5, an under side plan view of the parts shown in Fig. 4; Fig. 6, a detail Vertical sectional view as seen when looking in the direction indicated by the arrows from the dotted lines 6 6 in Figs. 2 and 3; Fig. 7, a detail vertical sectional view as seen when looking in the direction indicated by the arrows from the dotted line 7 7 in Fig. 3; Fig. 8, a detail or fragmentary view as seen when looking in the direction indicated by the arrows from the dotted line 8 S in Fig. 2; Fig. 9, a detail vertical sectional view as seen when looking in the direction indicated by the arrows from the dotted line 9 9 in Fig. 5, and Fig. 10 a detail vertical sectional view as seen when looking in the direction indicated by the arrows from the dotted lines 10 10 in Figs. f and 5.

The separator 50, the stacker-fan housing 51, the

conduit portions

52, 53, and 54:, and the means for revolving, elevating, lowering,

extending, and otherwise manipulating the same are or may be of any appropriate'or desired form of construction and are shown merely for purposes of illustration.

Mounted above the turn-table 60 is an annular toothed ring 61, which is driven by a worm-gear 62, mounted on a shaft 63, which in turn is driven from any suitable source of power, as an appropriate pulley and belt connection with some shaft of the separator. This annular ring 61 has an annular rack or spurgear 64: embodied therein or secured thereto, and upon a short shaft 65, carried in a suitable housing 66, (secured rigidly upon the stump or neck of the straw-stacked) is a spur-pinion 67, which engages with the spur gear-wheel or rack 64, and thus as the annular ring 61, carrying said spur gear-wheel or rack, is driven it, through the pinion 67, revolves said shaft 65. Another shaft 70, in line with or forming the pivot of the frame upon which the straw-stacker trunk or chute is swung vertically, is arranged parallel to the shaft 65, and these shafts 65 and '70 have upon their outer ends, respectively, sprocket wheels 71 and 72, and these are connected by the sprocket or chain belt '73. Upon the shaft 70 is also the bevel-pinion 75, and this in turn engages with the corresponding bevel-pinion 76 on a shaft, which runs up parallel with the straw-stacker trunk or chute and which is preferably divided into two

telescope parts

77 and 78, corresponding to the

telescope parts

53 and 54 of the stacker trunk or chute itself. Upon the outer end of this last-mentioned 5 shaft is another bevel-pinion 79, which engages with still another bevel-pinion 80 on a small transversely-arranged shaft 81, mounted in suitable hangers on the adjacent portion of the straw-stacker trunk or chute. This too last-mentioned shaft carries a worm-gear 82, and this in turn engages with an annular toothed ring 83, mounted revolubly upon the outer end of the trunk or chute of the stacker, which for purposes of convenience is of a curved or gooseneck form.

The nozzle or extreme delivery end of my improved stacker may be composed of either one or two pieces. I have shown it as composed of the two

pieces

90 and 91, as this gives a greater range of adjustment, as will be presently explained. The nozzle or nozzle part 90 is secured to the annular revolving ring 83 and is driven thereby, and consequently slowly revolves about the mouth or outer end of the stacker trunk or chute proper, as will be readily understood by an examination of the drawings, and is capable of delivering the straw or other material in a circle, and thus building a round or conical stack or pile. In addition to providing for this rotary or circumferential movement I also provide a means for increasing and diminishing the throw, and thus distributing the straw back and forth across the top of the stack, as well as discharge it in a circular path. This I do by making the nozzle in two parts and hinging one part 90 to the other part 91 by means of a pintle or pivot 92 and then providing means to swing said part 90 on its pivot, as will be presently described.

Within the annular ring 83, between it and the periphery or outer surface of the adjacent portion of the pipe or duct, is an annular rack or bevel-gear 95. Suspended by a suitable housing or bearing 96 to the ring 83 is a small shaft 97, having a bevel gear-wheel 98 thereon, which is provided with a wrist 99, and a pitman 100 runs from said wrist down to and is connected with the pivoted member 91 of the delivery-nozzle, so that as said wheel 98 revolves it serves to raise and lower or rather to swing said nozzle-section 91 on its pivot 92, giving the nozzle a vibratory as well as a circular movement.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. Thecombinatiominapneumaticstacker, of a nozzle revolubly mounted on the outerend of the stacker trunk or chute on an axis at an angle to the axis of the main portion of the trunk or chute, and power mechanism actuated from the main stacker-actuating mechanism whereby said nozzle is given rotation while the machine is in operation.

2. The combination,in apneumatic stacker, of the trunk or chute, a nozzle-section revolubly mounted on the outer end thereof on an axis at an angle to the axis of the main portion of the trunk or chute, gearing for revolving the same, a shaft leading from said gearing back to near the stump or neck of the stacker, and power-actuated gearing mounted at that point for driving said shaft.

3. The combination,inapneumaticstacker, 0f the vibrating stacker trunk or chute,ashaft at the pivot-point of the vibrating frame carrying the same, suitable power connections from said shaft to near the outer end of the trunk or chute, a rotatably-mounted nozzle at said outer end and adapted to be driven by said power connections, an annular ring mounted at the base of the trunk or chute adjacent to the shaft at the pivotal point of the swinging frame, means for driving the same around the stump or neck, and gear connections between said ring and said shaft.

4. The combination ,in a pneumatic stacker, with the trunk or chute thereof and the tu rn table on which the same is mounted, of an annular rim mounted above said turn-table and carrying a bevel-gear or rack, a short shaft mounted in bearings carried by the stump or neck of the straw-stacker and provided with a bevel-pinion engaging with said bevel-gear or rack, a second shaft mounted at the pivotal point of the frame on which the main stacker trunk or chute is pivoted, a driving connection between said two shafts, a bevel-gear on said last-mentioned shaft, a shaft running parallel with the main portion of the stacker trunk or chute, a gear thereon engaging with the last-mentioned gear, a rotatably-mounted nozzle on the outer end of the stacker trunk or chute,and power connections with the shaft arranged parallel to said trunk or chute for driving the same, substantially as set forth.

5. The combination,in a pneumatic stacker, of a rotatably-mounted delivery-nozzle composed of two sections one hinged to the other, suitable power connections for imparting rotary motion to said nozzle, a gear embodied in said power connections for driving a small crank-wheel, said crank-wheel, and a pitman leading from the crank-wheel to the pivoted member of the nozzle, whereby the extreme delivery portion of the nozzle is given a vibratory as well as a circumferential movement, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 10th day of April, A. D. 1902.

CHARLES N. LEONARD.
