corron-rroxna Specification of Letters Patent.

Application filed October 27; 1915. Serial No. 58,280.

1 all whom it may concern: a

lie it known that I, LINUS I). ARMSTRONG, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and'useful Improvements in Cotton-Pickers, lowing is a specification.

This invention relates class adapted for use chines and the like, invention is to prov in cotton picking 1na-' and the ob] cot of this ide' sucha grid bar hav ing its two opposite working edges beveled,

whereby the bar may be reversed edge for edge to bring the fresh working edge lnto operating position when the; first edge has been worn, thereby doubling the working tVith these and other objects in view, the

invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying 1- is a side elevation illustrating a gang of my improved grid bars in operative position also showing the adjusting means. Fig. 2 is a section on line 2-2 of Fig. l, showingone end of a grid bar as pivoted in the frame and the fingers or pins of the sliding plate as engaging the grid bars for the purpose of ad- Fig. 3- is a perspective view of one of the grid bars. Fig. 4 is a perspective view showing, a portion of the sliding plate, for adjusting the angle of the grid bars.

and 2, for the purpose of which the fol to grid bars of the "ture of this extending through the slot bolts 11 and 12.

of receiving the grid bars, presently described. This frame is curve of that on which'the grid barsare with a clownwardlyextending ear in which the operating handle is pivoted at 16, see Fig. 2. The grid bars 17- are formed of flat stock which is 'of'a] width much greater thanjits thickness both ends ofeach-bar is provided with-a short trunnion 18;" Anessential feai.nvention is that the opposite edges of each bar are beveledas at 27 and 28- to a: thin'edge, v

has been worn by constant work in themachine, the bar may be reversededge for edge to present a fresh working edge in place 'of the worn one, whereby of the bar is doubled. this invention is that the angle of the bevels on the oppositeedges are substantially parallel with eachotherQ These bars are set spaced apart between the two frames 10 with their trunnions rotatably, mounted in the notches 13, and a plate 19 is provided to lay against the frame with its pins or fingers 14 therein to engage the individual grid bars. This plate is also provided with a downwardly extendthe working. life Another feature of mg section of toothed rack 21, which is engaged by the segment 22, pivoted at 16 which segment is provided with an operating handle 23 A bolt 24, is passed through a slot 25 in thesegment memb be readily set up, made, to firmly retain the plate in adjusted position.

In the operation of this device the grid above de-' are lnserted 1n bars are beveled inthemanner scribed ,and their trunnions the openings. 13 whereby the bars are spaced apart and pivotally mounted between the frames 10.- Thisslide'bar 19' with its little amount of foreign matter it contains, therefore it isv found advisable to provide means whereby the'opening between the grid bars.

I er which "permits the movement of the same and which may after adjustment has been e cotton passed therestaple, and also in the Patented Feb. 1, 191 6.

so that when one edge bars it is only may be varied to suit conditions under which the machine is operating, therefore when it is desired to reduce the space between" the necessary to carry the handle portion 23 to the left until the bars are moved to the desired position after which the nut 26 ,is set up, and the whole remains set until adjustment is again required.

I have shown and described one form of mechanism for adjusting the angle of the grid bars, but the details of this mechanism may be varied without departing from the spirit and scope of my invention. 1 have also shown the grid bars as formed with the opposite edges of each beveled thereby making each bar reversible whereby its working life may be doubled and any means for accomplishing this object should be considered as covered by this patent.

I claim: 1 i

,l. A. reversible grid bar comprisinga flat bar having both of its opposite edges beveled to a thin working edge.

2. A reversible grid bar comprising a flat Copies of this patent may be obtained for five cen ts each, by addressing the bar havingeled on planes substantially parallel to each other and each having" a thin working edge, said bar being adaptedfto be reversed edge for edge.

3. A reversible grid bar comprising" a fiat bar having both of its opposite edges beveled on planes substantially parallel to each other each having a thin working edge, said bar being adapted to be reversed edge for edge, and means whereby said bar may be rocked to adjust its working angle.

4:. A reversible grid bar comprising; a flat bar having; its opposite edges beveled to a thin working edge, said bar being adapted to be reversed edge for edge, and a trunnion on the end of each bar whereby the same may be rotatably mounted.

In testimony whereof I aifix my signature in presence of two witnesses.
