ZZM y A TTORNEYI Roi-ed Sept. 17, 1910 UNITED STATES PATENT OFFICE PICK-UP MIEGHANISMI Geergelnnes, Davenport, Iowmslignortolnncs Bettendorf, Iowa, a corporation of 26 Claims.

The present invention relates to harvesting machinery and more particularly to pick-up mechanism for gathering vegetation which has been severed and left lying upon the ground. of course this can be used with a cutter mechanism so that the cutting and gathering will both be performed as parts of the same operation It is found that in rice fields a pick-up with rlgid'nngers has a tendency to gather and convey over to the apron or conveyor belt stones and chunks of dirt. This is thoroughly undesirable and it is the primary purpose of this invention to overcome this objectionable feature of prior machines. Other objects of this invention are the provision of an improved rotary means for picking up the cut vegetation: the provision of improved means for rotating the pick-up unit; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangement of parts illustrated in the acoomlllnring drawings and, while I have shown therein what is now regarded as the preferred embodiment of this invention, and an alternative form thereof, I desire this disclosure to be understood as illustrative only and not to be interpreted a limiting sense.

In the drawings annexed hereto and forming a part hereof.

construction embodying my present represents a side elevation taken from theleftsideofl 'lg. Lasindicated by thearrows Hg. 3 represents a longitudinal section through the pifl-tw unit in the plane defined by the axis ofthsdrumandthesxisofthecage;

Pig. resents a vertical transverse section ggin s is supported by suitable bearing elements 9 and III. A device I I for carrying the vegetation from the pick-up 8 to the apron 2 is rotated by a chain l2 running over a sprocket If on the shaft 8. This device ll, referred to herein as a slinger, is carried on a shaft It mounted in suitable bracekts adjacent the ends of the shaft.

The pick-up unit 3 comprises a drum l5 and cage it having spring fingers ll, together with operating means for the cage. As shown in Fig. 5, the sprocket wheels I and it, in the preferred form of this construction, are secured directly to the shaft 8. Therefore, when the chain 6 is driven from the source of power, the shaft 8 is rotated, driving the chain l2 and, through this, the slinger II. A sleeve llsurrounds the shaft 0 and is keyed, as shown at H, to the bearing unit It. If desired any suitable form of roller 01' ball bearin may be inserted between the sleeve i8 and the shaft 8. A collar 20 is rotatably mounted on the sleeve l8 and is secured to the end 2| of the drum I5. This furnishes a bearing for the drum on the sleeve. If desired, suitable bearing elements may be inserted between the collar 20 and sleeve it, although this is regarded as unnecessary because the rate and amount of rotation between these two is comparatively slight. The opposite end of the drum is supported by a suitable shaft 22 and bearing 23.

A bracket or arm 24 is keyed to the sleeve is by a key 25 and it is therefore apparent that since the sleeve is held stationary by the key IS the bracket or arm 24 will also be held stationary and at the proper angle, once it is properly set. This bracket 24 has a shaft 28 rotatably mounted therein and this shaft 26 cooperates with a like shaft at the opposite end of the cage It in supporting the latter in proper position within the drum It. Sprockets 21 and 28 are respectively mounted on-the shafts 2t and 8 and are located in the same plane, the sprockets being keyed to their respective shafts and connected by means of a chain 29. Therefore, rotation of the shaft 8 causes rotation of 'the shaft 26 and the cage It, which is keyed to the shaft 26.

The cage comprises a pair of ends 30 and a plurality of tubular bars 3i, the ends of which surround lugs 32, projecting inwardly from and formed on the inner faces of the ends 30. These bars are pinned to the lugs 32 and are therefore incapable of rotation about them. The spring fingers II are formed at their inner ends into coils 33 which are rigidly secured to the bars II by means of bolts 34. Openings :5, formed in the peripheral wall of thedrum II, have reill-axis. Itisalsoapparentthstifthesprlngfingers 16 is also apparent that the slinger n will receive ofthemechanismtowhichthisapronisto its bracket II is pinned to the opposite end of the shaft Ia and is therefore held in a rigid position because of the shaft being held rigidly. It is apparent from this figure that the sprocket I is keyed to the sleeve Ila instead of to the shaft, as in the previously described construction. Also, 40 the sprocket II is keyed to the sleeve Ila which is free to rotate in the bearing member ill, under the influence of the chain 8 and sprocket 1. In this form of construction, the drum I5 is free to rotate on the sleeve Ila, just as in the previously as described construction. In this construction, the sprocket II is keyed to the sleeve Ila instead of to the shaft, as in the structure previously described. The operation of this device is substantially the same as that shown in Fig. 5, the only 60 difference being that in one the solid shaft rotates and causes rotation of the cage and drum while the sleeve or hollow shaft is held stationary and, in the other form, the functions of the two parts are reversed.

as It is of course understood that the specific description set forth above may be departed from without departing from the spirit of this invention as set forth in this specification and the appended claims.
