FREDERICK LEE NORTON, OF RAOINE, WISCONSIN.

PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part Of Letters Patent No. 686,986, dated November 19, 1901.

Application filed May 6, 1901. Serial No. 59,026. (No model.)

To 60% whom it may concern.-

Be it known that I, FREDERICK LEE Non- TON, a resident of the city and county of Ra cine, State of Wisconsin, have invented certain new and useful Improvements in Pneumatic Straw-Stackers, of which the following is a full, clear, and exact description.

The invention relates particularly to improvements in the construction of the stackertrunk and to improvements in the mechanism whereby the elevation of the trunk may be varied.

The inventisn consists in the novel features of construction hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

Figure 1 is a view in side elevation, showing the lower or inner portion of the stackertrnnk and the mechanism connected therewith. Fig. 2 is a plan view in the direction of the arrow shown in Fig. 1. Fig. 3 is a detail front view of the toggle-link mechanism shown in side elevation in Fig. 1, and Fig. 4 is a view in vertical section through the swiveled sections of the trunk and through the shaft of one of the worm-pinions, the section being taken on line 4 4 of Fig. 2.

Referring'to the accompanying drawings, A designates the base-section or turret of the trunk that will be pivotally mounted in usual manner upon a suitable base, this turret-section being provided with an annular gear a, with which will engage a pinion, wherebythe turret will be revolved in order to swing the trunk from side to side when delivering the straw upon the stack. In prior constructions of pneumatic stackers it has been customary to connect the turret-section A of the trunk and the outer section or body portion B of the trunk bya telescopic joint,so that as the outer portion of the trunk is raised the continuity of the trunk may be maintained for the passage of straw therethrough. By my present invention the necessity of the employment of a telescopic joint or joints between the turret and body sections of the trunk is avoided. In the preferred form of this invention there is interposed between the turret-section A and body-section B of the trunk plural inclined or wedge-shaped pipe-sections C and G--that is to say, pipe=sections having a Fig. 4 of the drawings-that is to say, the turrot-section A has connected to its top a ring a, having an inwardly-turned edge or flange a that engages the outwardly-turned flange 0 of the ring 0', that is fixed to the lower end of the section C. In like manner the upper end of the section 0 has attached thereto a ring 0 the flange of which is engaged by the flange of a corresponding ring 0 attached to the lower end of the section C,while the outer end ofthe sectiouO has fixed thereto a flanged ring 0 that is swiveled by a joint like that shown in Fig. 4 to a ring b, secured to the inner end of the body-section B of the trunk.

In Fig. 1 of the drawings the sections 0 and O are shown with their shortest portions in downward position, and when in such position the body of the trunk B will manifestly extend outward in a substantially horizontal or but slightly-inclined direction. If, however, the sections 0 and C be turned in opposite directions, the longer portions of these sections will be moved toward the under side of the trunk, thereby lengthening such portion of the trunk and correspondingly shortening the upper side or portion of the trunk, with the result that the elevation of the trunk will vary in keeping with the extent to which the sections 0 and O are thus shifted. Manifestly the feature of maintaining the continuity of the trunk by the employment of revoluble sections intermediate its turret and body portions will be of value regardless of the means that may be used for effecting the raising and lowering of the outer or body portion of the trunk, although in the preferred form of the present invention this raising or lowering of the trunk: will be accomplished by the same means whereby the shift of the sections 0 and C is effected.

In order to maintain an alinement of the turret-section A and body portion 13 of the trunk when the sections 0 and O are revolved, a suitable extensible guard will be interposed between these sections. As shown, this guard consists of toggle-links d, d, 01 and (F. The

links d and d are pivoted together, as at 2, and have-their upper ends pivoted, as at 3, to the lower ends of the links d and d The lower ends of the links '61 and d are pivoted to sleeves d and d mounted upon a rod 4, that is carried by the ends of a bracket D, bolted, as shown in Fig. 1, to the band of a casting that encircles the turret-section A of the trunk. The upper ends of the togglelinks 01 and d are pivoted, as at 6, to a casting 7, the ends of which are journaled, as at 8, betweenthe arms of a bracket D, that is bolted to the ring I), encircling the body-section B of the trunk. These toggle-links, while serving to guard the body-section of the trunk against lateral movement independently of the turret-section A, will cause these sections to be swung in unison, while at the same time permitting the body-section B to be raised or lowered.

The preferred mechanism for effecting the revolution of the sections 0 and C will next be described. To these sections 0 and O are bolted, respectively, the segmental racks e and e, and with these racks engage the wormpinions f and f, keyed, respectively, to the shafts F and F. The shaft F is journaled in the arms of a bracket 9, bolted, as shown, to

the top of the turret-section A, while the shaft F is journ'aled between arms of a similar bracket 10, that is bolted to the lower or inner end of the trunk-section B. Between the shafts F and F extends the counter-shaft F, that is journaled in bearings g and h. The bearing g has arms g, that are pivot-ally connected to arms 2, extending outwardly from a sleeve 2' on the shaft F, while the bearing 71. is provided with similar arms h, that are pivoted, as shown, to arms 70, projecting from a sleeve on the shaft F. The shaft F is provided at its upper end with a beveled pinion f that engages with a corresponding pinion f on the shaft F, and the lower end of the shaft 15 carries a similar beveled pinion j, that meshes with a corresponding pinion f on the end of the shaft F. The pinion f is connected to the shaft F by means of a key entering a long groove f of the shaft, the purpose of this being to enable the shaft to slide freely through the pinion during the raising and lowering of the stacker-trunk. The outer end of the shaft F is shown as provided with a crank-handle f whereby the turning of the shaft will be effected.

From the foregoing description it will be seen that when the shaft F is turned by the handlef the pinion f upon this shaft will impart partial revolution to the segmental rack e, attached to the trunk-section C, causing said section to partially revolve in the direction of the arrow shown thereon in Fig. 2. Motion being transmitted from the shaft F by the counter-shaft F to the shaft F, the worm-pinion f of the shaft F by its engagement with the segmental rack e will impart partial revolution to the section 0 in the direction of the arrow shown upon said section.

As the sections 0 and O are thus partially revolved in opposite directions the outer or body section B of the trunk will be correspondingly elevated from the position shown in full lines toward the position shown in dotted lines in Fig. 1, the extent of its elevation being dependent upon the amount of revolution imparted to the sections 0 and 0'.

While I have described what I regard as the preferred embodiment of the invention, it will be understood that the details of construction above set out may be varied within wide limits without departure from the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- V 1. In a pneumatic stacker, the combination with the turret and the body portion of the trunk, of plural inclined sections intermediate said turret and body portion and revolubly mounted with respect thereto and means for revolving said inclined sections in opposite directions.
