DIVIDER-BOARD.

To all whom it may concern:

Be it known that 1 JOHN H. Kim, a citizen of the United States, residing at Bain, in the county of Aitkinand State of Minnesota, have invented certain new and useful Improvementsin Divider-Boards, of which the following is a specification.

This invention aims to provide a type of in which the major portion of the board is arranged to raise upwardly from the ground when swinging in toward the sickle bar so as to avoid any possibility of the board digging into the ground and being snapped off during the turning of the mower.

A further object is to provide a dividing board comprising a pair of hingedly connected sections, one of which sections is adapted to provide a guard or shield for the hinged joint while at the same time limiting the inward swinging movementof the other section.

With the above and other objects in View, the invention resides in the details of construction, combination and arrangement of parts, as will be hereinafter more fully disclosed, reference being had to the accompanying drawings, wherein- Figure 1 is a top plan illustrating one end 'of a sickle bar withthe invention applied thereto.

7 Fig. 21s a slde elevation and Fig. 3 is a horizontal longitudinal section of the invention, disclosing the manner in which the sections of the board are hinged together. 7

In the drawings, the improved form of dividing board contemplated by this invention is indicated at 1 and as shown consists of a member shaped after the-manner usual to boards of this character. For the purposes of the present invention, however, the board is divided adjacent one end and in a diagonal manner to provide a pair of sections 2 and 3 respectively, the former or short section constituting the head of the dividing board and being rounded as at 4: while the Specification of Letters Patent.

I latter or longer section constitutes the Wing or tail section which broadens out in a taper toward its outer end. 7

Fastened to the head 2 on one side isv a reinforcing strip or plate 5 which has a marginal portion bent inwardly to overlap and cover the inclined ed e of providing a contact face 6 to engage the contact face 7 ofa similar reinforcing strip 8 fastened to the side of the tail portion 4. Arranged over the strip 5 which is adapted and covering the entire side of the head is a plate 9 which is provided with a number of vertically spaced knuckles l0 projecting forwardly of the inclined or diagonal edge of.

the section to form half of a hinged joint by means of which the tail section is hingedly connected to the head for swinging movement. The tail section is likewise provided with a half hinge member complemental to the hinge plate of thehead andas.

illustrated, it comprises a plate 11 fastened to the board over the plate 8 and likewise carrying knuckles 12 positioned to fit into the spaces between the knuckles of the hinge plate .9 for completing the knuckle joint; the hinge being. ultimately completed by a pin 13, to hold the knuckles in place. This hinge is arranged to come on the inside of the board when the latter is affixed to the sickle bar of a mower so that the tail section may swing inwardly and over the bar. The outward swinging movement of the tail section is limited by the abutment of the contact faces 6 and 7, which contact occurs.

when the two sections of the board are in alinement with each other as shown in Fig. 1. The knuckles of the hinge it is to be noted, extend diagonally across the dividing board and by reason of this fact,the tail section when swinging inwardly on the hinge is caused to slant upwardly with the result that its under edge is radually elevated above the ground as the tail swings in wardly, thereby enabling the section to pass more readily over any stump or rough. ground when the sickle bar swings around during the turning or backing of the mower. It is a well known fact that at such time the turning movement of the bar is liable to result in a broken dividing board, since the latter is then most likely to strike up against some solid object in the field, suchas a stump, which may obstruct its passage and is apt to betsome broken by its contact therewith as the sickle bar swings around. But

the section, thus by providing a dividing board such as here disclosed and made up of sections connected together so that the rear portion swings inwardly when brought into contact with any object tendingto impede its swinging movement, it can be readily appreciated that the possibility of the board being broken is practically eliminated and by connecting the sections with a diagonal hinge, the tail section is enabled to not only swing inwardly out of the way of such impeding object but also vto swing upwardly and clear of the ground itself.

' The head 2 is provided with an additional member or outer plate 14: which is secured to the head by rivets or other suitable fastening means 15, which fastening means likewise secures the plates 5 and 9 to the head. This outer plate is flared adjacent the diagonal edge of the section 2 to provide a shielding flange 16 which projects over the knuckle joint of the hinge in the manner shown and serves to prevent wisps of grass, etc. from catching on the hinge or otherwise becoming entangled therewith. In addition to its function as a shield for the hinge, this flange provides a stop for limiting the inward movement of the tail section 8, the other edge 17 constituting, an abutment against which the hinge plate 8 will abut when the tail section has'been swung inwardly thereagainst.

In applying the invention to a sickle bar such as indicated at 18, the head 2 of the sectional' dividing board is inserted between the ears 19 of the guard 20, being fastened in place by a pivot or bolt 21 which passes through the openings provided therefor in the head of the board. The tail section of the dividing board extends rearwardly of the sickle bar in a straight line with the head 2 and as the bar swings in a circle as when turning a corner, the hinge enables the tail section to sway backwardly and over the sickle bar should it encounter any obstruction, the diagonal position of the handle tending to lift the tail section higher above the ground as it swings back. Being pivotally mounted between the cars 19, the dividing board is also permitted to move vertically upon the pivot 21, the rounded edge d moving across the sickle bar. Then the sickle bar is not in use and raised to a perpendicular position, the hinge permits the tail section of the board to hang down parallel to and rearwardly of the bar instead of straight back and annoying the driver it may be further turned out of the way by pushing the head 2 inwardly of its pivot so that the tail section hangs down on the inside of the bar and is spaced in parallel relation thereto.

It is obvious that the invention can be embodied in various structures and although the foregoing may be said to comprehend the preferred embodiment of the invention, such minor changes in the details of construction, combination, and arrangement of parts may be resorted to as fall within the scope of the appended claims.

Having thus fully described my invention what I claim as new and desire to secure b y Letters Patent is -1. A dividing board formed of two sections having adjacent ends upwardly and rearwardly inclined and a hin e connection at said ends. whereby one of the sections may swing inwardly and upwardly to one side of the other. 7

2. A dividing board formed of two sections having adjacent meeting ends upwardly and rearwardly inclined, a hinge connection for said ends whereby one section may swing inwardly and upwardly on one side of the other, and a hinge shield having a flared portion adapted to limit the inward movement of the swinging section. 5

3. A dividing board formed of sections having adjacent edges, a side plate on each section having a portion overlapping said edge, an outer plate disposed over the side plate of one of the sections, a hinge connecting the said sections at their adjacent edges, one side of the hinge being secured between the side and outer plates of one section, and a flared portion on said outer plate overlapping the hinge joint to provide a shield therefor and to limit the inward swinging movement of the opposite section.

t. A dividing board formed of sections having adjacent ends upwardly and rearwardly inclined, a hinge connection at said end whereby one section may swing upwardly and rearwardly of another, and means on a stationary section for shielding the ends and limiting the movement of a swinging section. In testimony whereof I afliX my signature in presence of two witnesses.

JOHN H. KILE.
