Specification of Letters Patent.
Patented Jan. 30, 1906.
Application filed February 6, 1904. Serial No. 192,293.
To (.tZZ whom it may concern:
Be it known that I, HENRY J. DAWS, a citizen of the United'States, residing at Hopkins,
in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Pneumatic Stackers, of which the following is a specification.
My invention relates to improvements in pneumatic stackers of the class wherein the discharge-trunk is made in hinged sections adapted to be folded back over the top of the threshing-machine when not in use. i
The object of the invention is to provide simple means for easily and conveniently manipulating the trunk-sections so that they may be folded back upon the threshingmachine and again extended without the employment of men upon the top of the machine to break the fall of the trunk in its descent or to raise the trunk when it is to be extended for use.
A further object is to provide improved means for holding the upper and lower trunksections together except when it is desired to fold the upper section back upon its hinge.
- To this-end my invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.
In the accompanying drawings, forming part of this specification, Figure 1 is a side view of a pneumatic stacker with the discharge-trunk in extended position, showing my invention applied thereto. Fig. 2 is a similar view showing the discharge-trunk folded back over the top of the threshingmachine, and Fig. 3 is a view of the under side of the discharge-trunk in the position shown in Fig. 1.
In the drawings, A represents the rear end of a threshing machine; B, the stackerframe; C, the fan-casing; D, the discharge throat or chute of the fan-casing, and E the discharge-trunk. For the sake of simplicity the discharge-trunk is shown broken away near its upper end, so that the hood and hoodadjusting devices usual to pneumatic stackers are not shown.
The discharge-trunk, as shown in the drawings, comprises a lower section 2, hinged at the bottom upon the inner side by a hinge 3 to the top of the discharge-chute D of the fancasing, and an upper section 4, hinged at the bottom upon the inner side by a hinge 5 to the top of the lower section 2, so that the trunk may be folded back upon these hinges into the position shown in Fig. 2. To ele vate the ,dischargetrunk in a vertical plane and pull it back upon these hinges, a cable 6 is secured to the threshing-machine at any convenient place, then passed over a pulley 7 upon the trunk near its upper end and thence carried back and passed over a pulley 8 upon the side of the threshing-machine, and finally passed over a Windlass 9, secured to the stacker-frame at any convenient place.
The arrangement so far described of hinged and foldable discharge-trunk and cable for operating the same is usual in stackers of this class, and the method of operation is obvious. When the trunk is to be folded back, the Windlass 9 is turned to wind up the cable and elevate the trunk-sections. These are held locked together by suitable means and swing as a whole upon the lower hinge 3 until the trunk reaches an approximately vertical position, when the locking means are released and the upper section folds back upon its hinge 5. As the upper section falls under its own weight it is received and its fall broken by a man or men mounted upon the threshing-machine. Similarly, when the trunk is to be unfolded and extended it must first be raised by hand to an approximately vertical positionthat is, it must be folded back upon the hinge 5, so that the two sections maybe locked together. To avoid this manual handling of the trunk and to facilitate the manipulation thereof from the ground at the rear of the stacker, I provide an arm or lever 10, secured to the upper trunk-section 4 near the lower end thereof, but upon the outer side thereof-that is, the side opposite to the l1ingeand extending downwardly and outwardly therefrom at an acute angle therewith. As shown in the drawings, this arm is secured to the lower end of the upper trunk-section by being bolted ,at 11 to a strap 12, passing around the trunk. To strengthen and stiffen the arm, it is preferably carried some distance along the upper trunk-section and bolted to a strap 13 higher up upon the trunk-section, and, if desired, the two ends of the arm may be connected by a tie rod or brace 14. The arm 1.0 is preferably extended downwardly and outwardly from the lower end of the upper trunk section a sufficient distance to bring its lower or free end beyond the line of the outer side of the lower trunk-section when the trunk is folded back into the position shown in Fig. 2, thereby keeping the operating-cable 15 away from the trunk and affording sufficient leverage for efficient operation, as well as enabling the operating-windlass to be arranged upon the outer side of the spout.
The operatingcable 15 is suitably connected with the lower end of the arm 10 and assed over a Windlass 16, secured to the ower section, on the outer side thereof, at a point near the lower end of the arm 10 when the upper section is in extended position, as shown in Fig. 1. As shown in the drawings, the cable is connected with the arm 10 by being passed over a pulley 17 ,carried by the arm, and the cable is wound at both ends upon the Windlass. It will be observed that when the cable 15 is wound up upon the windlass it will draw the arm 10 in toward the lower trunk-section and hold the upper trunk-section firmly against the lower section, so that it will not turn upon its hinge 5 and break back, thus dispensing with the use of locking bolts and pins, which cannot be quickly or conveniently manipulated. The Windlass is held from turning back to release the cable and upper trunk-section by suitable means, such as the pawl 18, upon the lower trunk-section and the ratchet 19 upo the Windlass.
To fold the trunk back over the threshingmachine, the Windlass 9 is turned to wind up the cable 6, as already described, the two trunk-sections being held locked together by the cable 15, so that the sections turn as a whole upon the lower hinge 3. When the trunk has reached an approximately vertical position, the pawl 18 is disengaged'from the ratchet 19 upon thewindlass 16 to permit the upper section to turn back upon its hinge 5. The Windlass 16 is then turned to unwind the cable 15, thus permitting the upper section to fall back gradually upon its hinge 5 until it comes to rest upon the top of the machine, as shown in Fig. 2. To unfold and extend the trunk, the Windlass 16 is turned to wind up the cable 15 until the upper trunk-section is raised upon its hinge 5 into alinement with the lower section, when the Windlass 16 is locked by means of the ratchetand-pawl mechanism. The trunk-sections then fall by gravity, turning as a whole upon the hinge 3 until the trunk comes into the position shown in Fig. 1
' It will thus be seen that the mechanism described furnishes a very simple, convenient, and easily-operated method of folding and unfolding the trunk-section by merely manipulating the two windlasses and also provides easily-operated means for locking and unlocking the two trunk-sections.
It is obvious that modifications may be made in the details of the device without departing from the principle of the invention, the scope of which is defined in the claims.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a pneumatic stacker, in combination, a foldable discharge-trunk having two hinged sections, an arm secured to the side of the upper section opposite the hinge, said arm ex tending downwardly and outwardly at an acute angle with said trunk-section and being of sufficient length to overlap the lower trunk-section when the trunk is extended, a cable connected with the arm and means upon the side of the lower section opposite the hinge for operating the cable.
2. In a pneumatic stacker, in combination, a foldable discharge-trunk having two hingeconnected sections, an arm secured to the side of the upper section opposite to the hinge, and extending downwardly and out wardly therefrom and at an acute angle therewith, said arm being of sufficient length to extend beyond the outer side of the lower section when the upper section is folded back, a cable connected with the arm, and cableoperating means upon the side of the lower section opposite to the hinge.
In testimony whereof I affix my signature in presence of two witnesses.
HENRY J. DAWS.
