Application filed April 11, 1908. Serial N 0. 426,608.

To all whom it may concern:

Be it known that we, EZRA G. GLYMANS and ANDREW M. HESS, residing at Waynesboro, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Straw-Stackers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to straw-stackers used in connection with threshing-machines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed whereby the strawstacker is made telescopic and whereby the straw is guided at its lower end.

In the drawings, Figure 1 is a side view showing an outline of the principal parts of the straw-stacker. Fig. 2 is a side view of one of the guards of the lower end of the elevator, drawn to a larger scale. Fig. 3 is a plan view of the said guard. Fig. 4 is a side viewof the driving devices for the telescopic upper section of the straw-stacker, drawn to a larger scale. Fig. 5 is a partial plan view of the same. Fig. 6 is a crosssection through the upper section of the straw-elevator, taken on the line ww in Fig. 5.

A is a portion of the frame of a horizontal straw-conveyer provided with an endless carrier B of approved construction. This straw-conveyer is provided with a drivingshaft a, and has the rear end portion 1) of its carrier arranged at an angle to the main portion of the said carrier and supported by suitable pulleys or rollers Z).

G is the lower section of a straw-elevator provided with brackets c at its lower end, which brackets are pivoted to the frame A concentric with the shaft 0;.

D is the straw-elevator carrier formed of an endless apron and provided with suitable cross-slats. The lower end portion of this carrier D passes over flanged pulleys E secured upon a driving-shaft (Z which is journaled in the brackets c.

The straw-elevator section G is troug shaped in cross-section, and it is preferably provided with a metallic bottom plate 0. The straw is delivered by the straw-conveyer between the bottom plate 0 and the straw-elevator.

In order to assure the delivery of all the straw to the straw-elevator in a satisfactory manner, guard-plates F are secured at the lower end of the straw-elevator. These guard-plates are similar to each other. Each guard-plate is arranged adjacent to the flanged end of one of the pulleys E, and is provided with a laterally projecting flange which overlaps the flange of the pulley. The guard-plate is provided with a hub f which is secured to the bearing in which the driving-shaft (Z is journaled, and it is also provided with a curved arm 6 which is bolted to the straw-elevator sidebar. The hub f projects laterally of the plate F and on the same side thereof as the flange 7, and the inner edge of the flange comes flush with the inner edge of the pulley flange, as shown in Fig. 3, so that the carrier is effective at this point for its full width. The flat portion of the guard-plate is arranged to the rear of the shaft (Z, and it and its flange f prevent the straw from catching and accumulating at this point, and also from being thrown out sidewise.

The lower section G of the elevator is preferably provided with a hinge G at its middle part so that it can be folded up, and g is a hook or other similar catch for bolding the parts of the lower section in line with each other. Guide pulleys g are carried by the lower section C for holding the upper bight of the carrier D clear of the lower bight.

H is the upper and slidable section of the The sides of this upper section straddle the sides of the lower section, and it is preferably provided with a bottomplate h of metal which slides under the bottom-plate c of the lower section.

I is a roller provided with a shaft 2' which is journaled in the upper end portion of the upper section H, and which supports the upper end of the elevator carrier.

J are arch-shaped brackets secured to the 1 upper end portion of the lower section 0 and overlapping the sides of the upper section H. J is a crosspiece between the free end portions of the said brackets.

K are brackets secured to the middle part of the lower section G. The brackets J are provided with clamps j, and the brackets K are provided with similar split clamps k.

L is a tubular guide secured in the clamps j and is at each side of the elevator and arranged parallel with each other and with the sections of the straw-elevator.

M are rollers mounted on pins m, and carried by arms m which project from the brackets J The side-bars of the upper section H run upon the rollers M- N are slides secured to the lower end portion of the upper section H, and a are antifriction rollers journaled in the said slides and running on the guides L.

O are sprocket-wheels journaled on pins which project from the brackets J, and P are sprocket-wheels secured on a shaft R which is journaled in the brackets K. Drivechains 79 of any approved construction pass over the wheels 0 and P, and have their lower bights arranged in the tubular guides L.

One end of each drive-chain is secured to one of the slides N, and its other end is secured to an arm 79 which projects from the upper section H. One end of each drivechain is provided with a tightening-device such as an adjustable eye-bolt. The shaft R extends across the straw-elevator, and it is provided with a crank-handle 1" on one end.

S is a check-pawl pivoted to the lower sec tion C and engaging with one of the drivechains so that the upper section cannot slide down by gravity.

T is a portion of the stay which supports the straw-elevator at any desired angle, and which is connected to the upper end portion of the lower sectlon.

U is a clamp for holding the elevator carrier in place when the elevator is folded up. Four of these clamps are provided, two being arranged on each side of the elevator. Each clamp consist-s of a cranked bar provided at one end with an arm a which is revoluble and slidable longitudinally in a socket V secured to the side of the elevator. A setscrew to is provided for securing the arm in the socket. WVhen the elevator is folded back onto the top of the threshing-machine, the arm is slid upward in its socket and is turned around so that the cranked bar can be pressed down onto the carrier in the trough of the elevator. The clamp is secured by the set-screw so as to clamp the carrier against the bottom-plate. The upper slidable section is moved in and out as occasion requires by revolving the crank-handle 1'. The elevator carrier is made in sections which are secured together so that they can easily be separated, and one or more of these sections are removed or added to suit the extension of the slidable section of the elevator. This telescopic straw-stacker is specially adapted for use in barns as it enables the straw to be deposited in different parts of the barn without moving the threshingmachine. The tubular guides protect the lower bights of the drive-chains from injury, and prevent straw from catching in them.

What we claim is:

1. In a straw-stacker, the combination, with an inclined straw-elevator provided with an endless carrier and having shaft bearings at its lower end, of a drivin shaft journaled in the said bearings and provided with flanged pulleys for driving the said carrier, and guardplates provided with laterally projecting flanges which overlap the flanges of the said pulleys and having also hubs which project laterally from them on the same side as the said flanges and which are secured on the said bearings.
