CHUTE FOR PNEUMATIC STACKEFTS.

SPECIFICATION forming part of Letters Patent No. 763,101, dated June 21, 1904.

Application filed January 4:, 1904.

T ln/,ZZ wiz/0m it may concern.-

Be it known that I, IIIILLIAM E. J oNns, a citizen of the United States, residing at Fargo, in the county of Oass and State of North Dakota, have invented-a new and useful Ohute for Pneumatic Stackers, of which the following is a specification.

This invention relates to pneumatic stacking devices; and it has special reference to the chute for conveying the material discharged at the tail end of a threshing-machine to the point of deposit.

The invention has for its object to provide and effective in operation and which shall to a large extent relieve the threshing-machine or separator upon which it is supported from the excessive and injurious vibration caused by the weight of the discharge-chutes as or- With these and other ends in view the invention consists in the improved construction, arrangement, and combinationof parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings I have shown of my invention, it being understood, however, thatI do not limit myself to the detailed construction therein exhibited, but reserve the right tosuch changes and alterations, especially with regard to size, proportion, and exact manner of assemblage, which properly come within the scope of my invention and which may be resorted to without departing from the spirit or sacrificing the utility of the same.

In said drawings, Figure l is'a top plan View of a portion of a chute to which my invention has been applied. Figs. 2, 3, 4:, and 5 are detail views illustrating members which enter into the construction of the device.

Corresponding parts in the several `figures are indicated by similar numerals of reference.

In carrying out my invention I employ a plurality of tapering or frustum-shaped tubular members, of which in the accompanying drawings four have been shown, said menibers being designated, respectively, l, 2, 3, and 4. One of these members, l, is to be Serial No. 187,691. @lo model.)

connected by a hinge at the base thereof with a straw-receiver, which strawmeceiver 1s connected to therdischarge end of the threshingi 4 is connected with a discharge-tube 5, only a portion of which has been shown in the drawings and which may be of any desired length. The members 1, 2, 3, and 4 are hingedly connected with each other by means of bracket members which extend rearwardly or outwardly from the base of the first member l, forwardly and rearwardly from the intermediate members 2 and, 3, (or as many intermediate members as may be employed,) and forwardly from the last or outermost member 4, the word l rearwardly being employed with reference to the direction of the discharge of material through the chute. The bracket members 6, which connect the first and second members 1 and 2, are disposed at the-sides of said members, and the pivotal pins 7, by which said bracket members are connected, are disposed approximately in a horizontal plane. The bracket members 8, which connect the members in rearof the 'first member, aredisposed, respectively, at the upper and lower vsides thereof, and the pins whereby said members are pivotally connectedsare disposed in planes at right angles to the connecting-pins 7 or in an approximately vertical plane. It follows that while the movement of the member 2 with relation to the member l is in an approximately vertical plane the members 2,

3, and 4 are capable of swinging relatively to the bases thereof with outwardlyfextending lugs l0, having slots or perforations 1l for the reception of connecting-rods 12,'which are disposed intermediate the Lhinge-joints which connect the several members, the said lugs IooA being connected in pairs by the said connecting-rods. Each of the latter is extended rearwardly of the rear of the lug through which it passes and is provided at its outer end with a nut 14. Tension-springs 15 are coiled upon said rods between the lugs through which they extend, and additional springs 16 are coiled upon the rods between the nuts at their outer ends and the adjacent lugs.

The brackets 6 and 8 and the lugs 10 may be secured directly to the bases of the respective members 1, 2, 3, and 4; but by the preferred construction herein shown said brackets and lugs are attached to reinforcing-rings 17, which are riveted or otherwise secured to the bases of the frustum-shaped tubular members. It is obvious that, if preferred, the said brackets and lugs may be cast integral with the reinforcing-rings; butinasmuch as such a change would be within the scope of ordinary mechanical skill it has not been specially illustrated.

, It is obvious that in any positionoil the chute the springs upon the connecting-rods serve to take up slack and to prevent rattling and vibration of the hingedly-connected parts. This has been discovered to be of the utmost importance, inasmuch as it vastly relieves the body of the machine to which a device of this kind is usually attached for operation from the strain incurred by the vibration of the chute supported thereon, which in practice has been found to rack the machine to such an extent as to cause frequent injuries. With my improvement the ordinary vibration of kthe machine while transmitted to the discharge-chute of the stacker will be taken up by the springs, and the obnoxious effects thereof will be reduced to a minimum.

It is obvious that the number of the hingedly-connected frustum-shaped sections hingedly-connected members having laterally-extending lugs, rods extending through and connecting said lugs in pairs, and tensionsprings upon the said rods.

2. In a device of the class described, tapering tubular members hingedly connected and having laterally-extending lugs, rods extending through and connecting said lugs in pairs, tension-springs coiled upon said rods between said lugs and upon extended ends of the rods, and spring-adjusting nuts upon" the latter.

3. In a device of the class described, tapering tubular members having brackets, pins hingedly connecting said brackets, lugs extending laterally from the bases of the tubular members, rods connecting said lugs in pairs, springs upon said rods between the lugs connected thereby, springs upon the extended ends of said rods, and spring-regulating nuts upon the latter.

4. Ina device of the class described, tapering tubular members, reinforcing-rings at the bases of said members, brackets and lugs extending from said rings, said lugs being disposed intermediate the brackets, pivotal connecting means for the brackets, rods connecting the lugs in pairs, springs upon said rods between the lugs, springs upon the exy tended ends of the rods, and means for conining said springs.

5. In a device ot' the class described, a plurality of tapering tubular members, hingedlyy connected brackets extending from said members and connecting the latter to swing 1n planes at right angles to each other, lugs extending from said tubular members intermediate the hinge connections, rods connecting said lugs in pairs, springs upon said rods between the lugs, and springs upon the extended ends of the rods, and securing means.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

WILLIAM E. JONES.
