SHEAFCARRIER AND DUMPER FOR HABVESTERS.

SPECIFICATION forming part of Letters Patent No. 524,991, dated August 21,1894.

Application filed May 12, 1894.

To all whom it mag concern..-

Be it known that I, SYLVANUS D. LOCKE,

Jr., a citizen of the United States,- residing at Hoosick Falls, county of Rensselaer, and State of New York,have invented certain new and useful Improvements in Sheaf Carriers and Pumpers for Harvesters, of which the follow- -1ng 1s a specification.

wardly toward the machine in delivering the sheaves, and has especial reference to such devices 1n which thefingers are mounted upon and operated by a rock shaft.

The object of this invention is to provide a machine by means of which the delivering fingers will individually and collectively be operated to deliver the sheaves and also to pass obstructions and automatically return to their normal position, and also to fold upward and backwardagainst the end of the delivering table to narrow the machine for transportation from field to field or along the highway.

The invention consists inthe construction and arrangement for this object of the various devices as hereinafter set forth and claimed.

Referring to the accompanying drawings, Figure 1 is a plan view of a part of the harvester showing the carrier in its normal position. Fig. 2 is a front view in elevation of the same. Fig.3 is a plan view of an enlarged portion of the rock shaft, a finger sup.

port and finger in normal position. Fig. 4 is a plan view of the carrier in dumping position. Fig. 5 is a front view in elevation of the same. Fig. 6 is a detail plan view of an enlarged portion of oneof the fingers,its support and the rock shaft in dumping position. Fig. 7 is a plan view of the carrier in its final discharging position. Fig. 8 is a front view in elevation of the same. Fig. 9 is a detail plan View of an enlarged portion of one of the fingers, its support and the rock shaft in the final discharging position shown in Fig. 7. Fig. 10 is a view in perspective of the invention illustrating the manner in which the fingers clear an obstruction. This figure also shows in dotted lines the fingers folded up and back for transportation. Fig. 11 is a Serial No. 510,966. (No model.)

Fig. 13 is afront end viewof the rock shaft, its crank and bearing. Fig. 14 is a cross section of the rock shaft and a rear view of its crank and front bearing. Fig. 15 is also across section of the rock shaft and a rear View of a finger support, as in position shown in Figs. 1, 2 and 3. Fig. 16 is an under side .view of the same with the shaft cut away.

So much of a harvester as is necessary to illustrate this invention, is shown on the frame A, on which is mounted a rock shaft B, located beneath the binding or delivering table 0, and operated by a crank arm a, rod 1) and the proper connections extending to the drivers seat.

Dare the fingers which are mounted and rest at their inner ends in supports E secured a to rock shaft B. The fingers may be bent upward as shown in Figs. 2, 5 and 10, to more readily hold the sheaves. In delivering the sheaves, the fingers are lowered from the horizontal or normal position, shown in Figs. 1 and 2, by means of the rock shaft B, operated by the driver.

In order that the fingers may be brought to a discharging position alongside of the matomatically return to their normal position; and in order that they may individually and collectively automatically clear obstructions, as shown in Fig. 10; and, in order that the folded carrying position for transportation from field to field or alonga highway as shown by dotted lines in Fig. 10; the. fingers and as follows:

The supports E, bolted or otherwise secured to and extending about the rock shaft B, are formed with the rear projecting portion e, having the perforation e in which is located and loosely mounted the rear end g, of the finger D, so as to permit of a rolling and vibratory movement thereof and forming a universal joint.

(1 indicates a front enlarged portion of the support E, provided with the triangular opening d, through which extends the finger D.

chine, as shownin Figs. 7and 8, and may aufingers may be also brought to a final upward their supports are constructed and arranged This opening or slot is made wider atthe top than at the bottom to give the fingers more freedom'of. motion when dumping or clearing obstructions, that is, when rising from the bottom of the opening.

The portion of the support E, between the ends d and e, is curved outwardly so as to form a recess, chamber or socket between the support E and the rock shaft B, in which recess is located the curved or bowed portion 9 of the finger D, the curved portion 9 normally bearing against the rock shaft B, as shown in Figs. 3, 6 and 9, and preventing the fingers from rolling when in the normal position. a

The straight portions 9' and g of the fingers D are at an angle to the main portion of the fingers, but are in line with each other, and in the same vertical plane with the finger when in a carrying position,-and form the axes of rotation of the fingers. The plane of thebowedportion g, of the fingerD is at an angle to the plane of the remainder ofthe finger. This makes the angle between the plane o'f g and that portionof the rook-=shaft upon which it slidesalways other than a right angle and obviatesthe necessity of interposing' an inclined slideway between g and-the rock shaft B.

By nieans'of the foregoing construction and arrangement of parts, when the fingershave been lowered bytherotation'of-the-rockshaft until their outer ends encounter the ground,

the fingers will trail rearward, the portion from the recess wall or stop), and sliding on the'rockshaft B canses the ,fingerD- to tilt upward, the fingers in this movement rolling on their longitudinal-axis; Should thehar:

vester be raised or lowered or tilted when the fingers are folded beneath the rock shaft, the

width of the'upper part of the opening'd will permit. of enough vibratory movement-of'the fingers to prevent them from leaving-the groundwhen machine'is raised or being driven into it when'machineis lowered. On rotating the rock shaft 'B back again to restore the fingers from the trailing tilted position to the normal position and when the of the opening d, the fingers are .again' rotated to their upright normal positions. "The bowed portion g, during its rotation; slides upon the rock shaft B until it'strikesthe recess wall or stop f..' This sliding'isinsured by the-portion got the fingerD beingbent at anangle to the plane of themainpart'of the finger,:as described.

It'will readily be seen also that this construction and arrangement of the fingers and their connections are. also advantageous in that the fingers individually and collectively ."Will easily andeffectively clearany obstruction, however high as a stump or tree. shown in Fig. 10, each fingerbeing pushed back by the obstruction and yielding rearwardly and upwardly to ride over the obstruction and then rolling and falling back automaticallyto the normal position. In handling the sheaves the fingers act in-unison, the rotation of the rock shaft contributing to their movement, while in encountering obstructions the fingers act individually and without operating the rock shaft to ride over the obstruction and to fall by gravity back to their normal position. 7 I

Another advantage of this invention is that should a sheaf be dropped'on the fingers before they had entirely reached their horizontal position, the movement of the fingers would be accelerated thereby, and. should a sheaf be discharged onv to thefingers while they were clearing. an obstruction, thesheaf "would not escape fromthe fingers. 1s also apparent from the describedwconnection: and

arrangement of the. :fingers'. and :finger supports and their connections, whichh'as been demonstrated practicallyin a full sized .ma-

chine, that if, when in the normal :position shown in Fig. 1, the fingersbe'rais'edl-by the 1operator,"at=the same time I slightly rotating the rock shaft, .they'will. fall: backwardly and zcrearwardly as shown by dotted linesin Fig.

10, the centers of gravityofrthe finger-shavring passed within or. beyond' the rock shaft, "intothe rear upper anglesof thestriangular openings in the finger supportsyor against rthe-outer edge of. the-deliveringlable O, the concave sides. of the teethstriking. the table 1 so that the ends are inside of the outer edge of the table, wherelthey can be securelycar- .ried. in. the transportation of the harvester and binder from field: to: field 'OI'.. along the highway.
