SHEAF-CARRIER.

SPECIFICATION forming part of Letters Patent No. 420,274, dated January 28, 1890.

I Application filed May 14, 1889. Serial No. 310,738. (No model.)

To aZZ whom it may concern:

Be it known that I, EDWIN M. KELLOGG, a citizen of the United States, residing at Delavan, in the county of Walworth and State of Wisconsin, have invented certain new and useful Improvements in sheaf-Carriers, of which the following is a specification.

The obj ect of this invention is to construct a slatted carrier in such manner that it may be tilted directly upon an axis transverse to the line of advance of the machine or parallel with the line of reception of the sheaf, but may yield and fold in, each individual finger by itself, upon meeting any obstruction or for the purpose of passing through a gate, and to this end a rocking supporting bar is mounted upon the fore part of the harvester-frame, projecting therefrom at right angles to the line of advance of the machine, and to this bar are secured a series of fingers or teeth having individual pivots thereon that permit them to fold parallel with the bar. A second bar, preferably in front of the rocking bar, lies parallel therewith, and is connected with said teeth by keepersone for each tooth or for a heel-extension thereof and is also connected with the harvesterframe by a rod or guide which permits its vertical play and stops it against endwise displacement, thus insuring a sort of parallel movement to the two bars and to the teeth whenever said bars are by any means swung rearward on their pivotal connections with the frame, shutting the teeth in alongside of the rocking bar. A spring holds the rocking bar in its normal position at right angles to the line of advance of the machine, and a lever-connection, with controlling devices operated by the driver, enables said bar to be held against rocking on its longitudinal axis or released that the carrier-fingers may fall and dump the load.

In the drawings, Figure 1 is a top plan View of a carrier constructed according to my invention, showing also part of the harvester- Fig. 2 is a rear elevation thereof,

showing grain deck or chute and elevatorframe, the latter in section; Fig. 3, an elevation of the carrier from the stubble side, ex-

plaining its operation in dumping; Figs. 4

and 5, enlarged details in top plan and stubble side elevation of the mechanism for supporting and operating the carrier; Fig. 6, a like detail in transverse section seen from the rear, and Fig. 7 a top plan view of the main bracket whereby said carrier is sup ported.

A represents the rear platform-sill and A the rear elevator-sill, B the front platformsill and finger-bar, and B the front elevatorsill, of a harvester, these sills, except the front platform-sill, being herein shown as formed of square pipes, as are also the crossgirts of the elevator-frame, but this form being selected only as an exponent of any suitable construction.

O is the main wheel, and D the outer girt; E, the grain-deck receiving from the elevator E, and having at its foot or discharge end a delivery-board E, as usual in modern grainbinders. Automatic binding mechanism of any appropriate type will of course be located over and beneath this grain-deck; but it is not deemed necessary to show it in the drawings. I

F is a supporting-bar for the carrier-fingers rocking in a horizontal bearing or bearings f, formed in a swiveling block G, which is preferably supported upon a'bracket G, secured to the outer girt or one of the outer girts of the machine. Toward the front end thereof the swiveling block is connected with the bracket by a pendent pivot-pin g, which turns in a vertical sleeve 9' on said bracket, so that the block may be swung about in a horizontal direction to permit the rocking supporting-bar to fold in toward parallelism with the girt. At its outer or stubble end the block carries a small anti-friction wheel 9 traveling upon a segment-track g outsetting from and forming part of the supportingbracket and arranged in a horizontal plane, thus giving two points of support to the rock ing barthe first that which is due to the connection of the pivot-pin with its sleeve, and the second that afforded by the segmental track; but it will be understood that this track is mainly for additional support and greater security, and may be modified or dis pensed with under suitable circumstances.

taining their parallelism with each other, to

spring.

To the rocking bar, which will beadvisably of gas-pipe, is secured a series of rearwardlyprojecting carrier-fingers K, each having an individual upstanding pivotal connection is with said bar, so that it may be folded in theretoward and brought practically parallel therewith. These pivotal connections are herein shown as formed by a vertical bend in the body of the fingers passing directly through the bar; but it is obvious that other means may be adopted.

In front of the rocking bar is another but lighter bar L, parallel therewith and connected to a heel-extension I from each finger by vertical pivot-pins Z, which may be integral with such heel-extension, as shown, so as to permit such extension to fold practically into receiving position of the carrier and the latter the limit of the dumping movement. This 3 rod or guide permits a hinge movementto the controlling-bar that it may be swung inalongside of the girt whenever the carrier meets an obstruction, but prevents endwise' movement of said bar, so that as long as the rocking bar is in its normal position the carrier-fingers must remain parallel with eachother-at right angles to said rocking bar and parallel with the line of advance of the mavaried in details, and I do not therefore inchine.

Now, supposing that the carrier meets a stump or other obstruction of such height that it cannot pass over it, the controlling-bar,

and the rocking-bar as well, will be pushed back, swinging upon their pivotal connec close in or shut in toward said bar and each other to an extent determined by the proximity of the obstruction to the end girt. As soon, however, as this obstruction is passed the force of the spring will return the rocking supporting-bar to its normal position,

carrying with it the controlling-bar and the carrier-fingers, which will spread apart from each other until once again in receiving position, when further movement will be barred by the stop at the front end of the segmenttrack.

As thus far described,-it is evident that the carrier is free to tilt whenever a sufficient load is brought upon its fingers to overcome their balance, or in case that part of the fingers to the rear of the rocking bar is of sufficient weight to overcome the aggregate weight of the heel-extension and controllingbar. In order to prevent this and bring the time of tilting or discharging under the control of the driver, a long bell-crank N is arranged in front of the elevator-frame, being supportedat one end in a bearing n at the forward end of the outer girt and at the other end in a bearing n, projecting from the seat-' the rear, as above explained. The lever-arm n at the other or inner end of the bell-crank receives one end of a foot-bar N extending rearwardly over the seat-plank and j ournaled upon a stirrup O, which swings in a bearing upon said seat-plank, so that when the bar is pushed to the front by the drivers foot it will hold the carrier-fingers in their receiving position, and when released will allow said fingers to drop to dispose of their load.

A strap 0 is or maybe applied to the rear end of the footbar, so that the foot which rests therein may be used to draw the bar back to aid the tilting or dumping movement in case this should be necessary. v

It will be understood that the construction IIO of my improved carrier may be somewhat tend to limit myself to the precise arrangement described herein and shown in the drawings; but

What I do claim is- 1. The combination, substantially as hereinbeforeset forth, of the horizontal rocking 7 bar, its bearing-block connected by a pendent pivotal pin to the machine, aseries of carrying-fingers having independent pivotal connections with said rocking bar, and the controlling-bar parallel to said rocking bar, and also connected with said fingers by independent pivotal connections.
