STRAW-STACKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 486,346, dated November 15, 1892.

Application filed July 1, 1891. Renewed October 11, 1892. Serial No. 448.503. (Model) To all whom it may concern:

Be it known that I, AUGUST LAMMEDEE, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Straw-Stacking Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompa nying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a detail side elevation of the carrier-sections, receiver-section, and their connections and operating devices folded. Fig.

2 is a similar view of the same partly extended; Fig. 3, a similar view wholly extended. Figs. 4 and 5 are details.

This invention relates to straw-stacking ma chines, and is an improvement upon the stackers shown and described in my Letters PatentNo. 385,634,0fJuly 3,1888, and No. 430,863,.

of June 24, 1890;-and it consists in the novel construction and combination of parts hereinafter described and claimed.

Reference being had to the drawings by letter, A designates the lower section of the carrier, which is mounted upon front and rear pivoted legs or hinge-bars B B, which are in turn pivoted to a rotatable or oscillating carriage O, mounted on annular bearing-rings C 0 the lowest one of which is fixed on a supporting-frame X. The carrier belt in the lower section is driven by belting and pulleys from the main shaft D, which also operates the carriage. The sections can be oscillated or elevated by means of a rope or chain c, the ends of which are attached to drums on a transverse shaft on carriage (J and run thence up over pulleys e, journaled in the upper ends of uprights E, attached to the carriage, thence down under pulleys e on the ends of a shaft E, connecting bars B to the lower section, thence up over pulleys 6 mounted in uprights E above the pulleys c, then passing down under the lower section, as indicated in the drawings. All the aforesaid parts are constructed and operated subreversed the stacker will not be set in motion. The front and rear bars B and B being. of unequal length, when ropes e are tightened the sections are raised and simultaneously thrown forward, describing an arc-shaped path, the rear end of the carrier rising faster than its front or receiving end. In order to prevent this double movement, yet allow the rear end of the carrier to be elevated, if de sired, I employ hooks F, pivoted to the side of the carriage, and which can'be engaged with pins f on the sides of section A, near pulleys e, or with the ends of the shafts of said pulleys. These books will hold down section A and cause it to oscillate on shaft E as a center when ropes e are tightened, as the ropes will lift the rear end of section A toward pulleys 6 e thereby raising the delivery end and slightlydepressing the receiv-- ing end of the carrier, and it is therefore necessary to make the connection at one end of bars B loose to permit thismovement. I prefer to slot or loop the upper ends of bars B, as indicated in Fig. 5.

The driving-shaft A of the carrier-belt in the section passes through these slots or loops, and when hooks F are disengaged the weight of the delivery end of the section will normally hold the shaft in the upper ends of the slots.

When hooks F are disengaged, the rope (2, when tightened, draws pulley 6 toward pulleys 6 e lifting the carrier in the manner described. These hooks are useful when the.

stacker is employed with clover-hullers or low thrashers, as the receiving end of carrier of carrier-section Aand adapted to be turned over on section Aduring transportation. The sections are connected by hinges G and the part 9 of the hinge connected to section A has an elongated slot in its upper end, in which plays a stud on the part g of the hinge connected to section A. By this hinge when section A is turned over upon section A it can move longitudinally in over the latter sufti cient to prevent the under side of the endless carrier-belt a, which runs over both sections,

beingstrained at the bend when the sections are folded, thus enabling meto shorten the carrier-belt so that there will be little or no slack therein when the sections are extended.

To the hinged ends of section A is attached projecting arms H H, which are connected at their free extremities by links h to a rod h. By grasping this rod and pulling down there on the upper section A can be folded or extended, as is obvious, and when extended the rod 71, underlying section A, serves to brace and sustain the upper section, as will be apparent from the drawings.

I designates the receiver or hopper, which is of ordinary form, but rests and moves upon the sides of section A, being provided with fingers t z, which prevent it slipping laterally olt the section.

lion longitudinallyof the section by rods Jj for holding down the rear end of the section J, which are pivoted .to the receiver and :to the upper ends of uprights E By reference to the several figures it will be observed I that these rods cause the receiver to lreep al- The receiver is held in ,posi- Y most in the same vertical position above the carriage, causing it to shift its position on the lower section or allowing the lower :section to shift thereunder as it rises and moves forward. By this means the receiver is always imposition beneath the delivery-trough of the thrasher, the, sothat the straw is properly delivered thereto, whereas when the receiver has been fixed tothe carrier-section it shifts horizontally as well as vertically and the .machine has to be shifted as the stack rises or the straw is not properly and cleanly received by the stacker.

These several improvements and their utility having been now described, what I claim as new isl. The combination of a carrier and means for moving the same both vertically and iongitudinally,with a receiver slidably supported on the lower end and guided by the sides of the carrier, and the rods pivotally connected to the receiver and to a fixed upright separate from and beside the carrier, whereby the receiver is permitted to move only in a substantially-vertical plane, substantially as described.

2. The combination, in afolding carrier, of a section having hinge-plates g, having elongated slots in their upper edges, substantially as described, attached to the ends of its sides, with a folding section having hinge-plates g, having studs on their upper inner corners, substantially as described, attached to the ends of its sides, the studs of plates g engaging the slots of plates g, forming a slidable hinge-j oint between the sections, substantially as specified.

3. The combination of the carriage, the carrier mounted thereon, and means, substan' tially as described, for adjusting and supporting the same, with the hooks attached to the carriage adapted to engage and hold down the carrierbut permit its oscillation, substantially as and for the purpose described.

4. The combination of the carrier-section, the front and rear bars supporting the same, said front bars having a loose connection, and means for elevating the carrier, with devices but permitting it to oscillate, substantiallyas and for the purpose specified.

5. In a folding carrier, the combination of a lower section and an upper section hinged thereto with the arms attached to the hinged end of the upper section and the rod connected to the extremities of said arms and adapted toengage the fixed section, substantially as and for the purpose specified.

6. In a straw-stacker, the-combination of a vertically and longitudinally adjustable carrier and means, substantially as described, for adjusting the same, with the hooksFand pins f, substantially as and :for the purpose set forth.

7. The combination of the adj ustablesection A, the fielding section A',thehinge-joints uniting the sections, the receiver 1, slidably mounted on section A, and the rods J, pivotally connected to said receiver and to fixed support beside but independent of the section, substantially as described, and mechanism for adjusting saidsections, all constructed and arranged to operate substantially as described.

In testimony that I claim the foregoing :as my own I affix my signature in presence of two witnesses.

AUGUST LAMMEDEE. Witnesses:
