`PNEUMATIC STACKER.

SPECIFICATION 'Oxm'mg part of Letters Patent No. 685,628, dated October 29, 1901. Application filed May 6, 1901. l Serial No. 59,022. (No inoclel.)

To all whom, it m/cty concern/.-

Be it known that I, GEORGE W. MORRIS, a resident of the city and county of Racine, in the State of iVisconsin, have invented certain new and useful Improvements in Pneumatic Stackers,of which the following is afull,clear, and exact description.

This invention relates to pneumatic strawstackers, and has for its object to provide iinprpved means for varying the elevation of the stacker-trunk.

The invention consists in the features of improvement hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification. p

Figure 1 is a view inside elevation showing the lower or elbow portion of the trunkpipe of a pneumatic stacker having my invention applied thereto. Fig. 2 is a View in cross-section on line 2 2 of Fig. Vl. Fig. 3 is a view in crosssection on line 3 3 of Fig. l. Fig. A is a view in side elevation showing a modified construction embodying features of the invention. Fig. 5 is a view in cross-section 011 line 5 5 of Fig. 4.

The elbow portion ot the discharge-pipe or trunk isshown as consisting of telescopic sections A and B, the'se'ction A being shown as provided at its base with a gear-wheel tt, whereby the revolution of the discharge-pipe or trunk will be edected in a manner well uny derstood by those-familiarvwith this class of devices. The section A will be mounted in the usual or suitable manner upon a base or turret, (not shown,) and the section B will have connected thereto an outwardly extending body portionpof any desired length. .t The section B isr of sufficiently greater diameter than the section A to set over the same and is of such curvature as to permit it to move downwardly over the upper part of the section A when the body portion of the pipe is to be raised. Uponeach side of the elbow-section A ris formed a segmental rack ct', that sets within channels b of like curvature formed at each side of the section B. The pi pe-section B is preferably a two-part casting divided longitudinallyand having its abutting edges formed with lugs or iianges 2, whereby the parts may be conveniently bolted together. v

journaled in'brackets 3, rising from the upv per part of the pipe-section B. Upon the shaft F is keyed a worin-wheel'G, with which meshes a worm-pinion G', that is fixed to shaft g, journaled in the bracket V5, extending upward from the adjacent bracket 3. One end of the shaft g is furnished with a hand-wheel G2, whereby the shaft may be conveniently I turned. Y

Theoperation of parts as thus far described is as follows: When the elbow or pipe sections A and B are in the relation shown in Fig. l, it will beunderstood` that the body portion of the trunk or discharge-pipe is in approximately'l horizontal position. If now it is desired to'raise the body portion of the discharge-pipe 'or' trunk, the operator will turn the hand-wheel G2,"thereby causing the worm-gear mechanism to .impart revolution to the shaft'F and from `this shaft and its pinion E to the gear-wheels D. As the-gear wheels `D 'are thus revolved their engagement with the teethjof the segmental racks a will cause the pipe-section B to move downwardly in the direction of the arrow, Fig. 1, thus correspondingly effecting the elevation of the discharge-pipe or trunk carried by the section B.

In the modified form of the invention illustrated in Figs. 4 and 5 the elbow is shown as formed of telescopic curved sectionsA'- and B'. The section A is provided upon its upper side with a segmental racki and upon its lower side with a correspondingv segmental rack 7 of shorter curvature.V The section A' sets within the section B', and the racks 6 and 7 are received by corresponding channels IOO 8 and 9. The section B' is preferably a twopart casting, its flanged edges being bolted together, as at 10. As shown, the pipe-section B' is provided adjacent its lower end with bearings 12 and 13, in which is journaled the shaft 14, that carries a pinion 15, engaging withthe lower segmental rack 7 on the pipesection A'. In like manner the top portion of the pipe-section B' is provided with bearings 1G, wherein is journaled the shaft 17, to which is keyed a pinion 18, that engages the upper segmental rack 6 ot' the pipe-section A'. The shaft 14 has keyed to its outer end a pinion 19, that meshes with a pinion 20, journaled upon a stud projecting from the side of the pipe-section B', and this pinion 2O in turn meshes with a gear-wheel 21, journaled upon a stud projecting from the side of the pipe-section B'. The gear-wheel 21 meshes witha pinion 22, keyed to the shaft 17, and upon this shaft is also keyed a worm-pinion 23, that is driven by a worm 24, fixed to the shaft 25. The shaft 25 is journaled in the frame 26, conveniently bolted to the top of the pipe-section B', and the outer end of the shaft 25 is provided with a hand-wheel 27, whereby it may be operated.

From the foregoing description it will be seen that when it is desired to raise the body portion of the discharge-pipe or trunk it will be connected to the pipe-section B', and the operator will turn the hand-wheel 27, causing the wornngearing to impart revolution to the shaft 17 and from this shaft by the gearwheels 22, 21, 20, and 19 to the shaft 14.. As the shafts 17 and 14 are thus revolved their respective pinions 18 and 15, being in mesh with the corresponding segmental racks 6 and 7 of the pipe-section A', will draw downward the section B' over the section A', thus causing the elevation of the trunk or body portion of the discharge-pipe that will be connected to the free end of the section B'. It is manifest that the segmental racks 6 and 7 and the gearing that connects the shafts of the pinions engaging said racks will be properly proportioned, so as to impartan easy movement of the pipe-section B' over the section A'.

The details of construction above set out may obviously be varied by the skilled mechanic without departure from the scope of the invention.

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

1. In a pneumatic stacker, the combination with a discharge-pipe or trunk having curved telescopic sections of plural racks longitudinally mounted upon one' of said sections and pinions engaging said racks mounted upon the other of said sections, and means for operating said pinions.

2. In a pneumatic stacker, the combination with a discharge-pipe or trunk having curved sections, of rack-bars at opposite points of one of said sections, pinions engaging said rack-bars carried at opposite points of the other of said sections, and suitable gearing connecting said pinions.

3. Inapneumatic stacker, the combination with a d ischarge-pipe or trunk having curved telescopic sections, of rack-bars upon the inner section and pinions mounted upon the outer section engaging said rack-bars, and suitable gearing connecting said pinions.

4. In a pneumatic stacker, the combination with a discharge-pipe or trunk having curved telescopic sections, of rack-bars at opposite points of the inner section, channels to receive said rack-bars at the opposite points of said outer section, pinions carried by said outer section for engaging said rack-bars and suitable gearing connecting said pinions.

5. In.a pneumatic stacker, the combination of a dischargepipe or trunk having two curved telescopic sections, ot' longitudinal curved racks mounted on one of said sections, pinions engaging said racks mounted upon the otherof said sections, gearing connecting said pinions and worm-gearing for operating said gearing.
