ROBERT W. WALLACE, OF MONTESANO, WASHINGTON.

MOWING-MACHINE ATTACHMENT.

Application filed November 25, 1919.

To all whom it may concern Be it known that I, ROBERT W. WALLACE, a citizen of the United States, residing at Montesano, in the county of Grays Harbor and State of Washington, have invented a new and useful Mowing-Machine Attachment, of which the following is a specification.

This invention relates to attachments for mowing machines, and particularly to that class of attachments known as fender rods.

In mowing machines as usually constructed, when heavy grass is being cut, it will collect in bunches, which when encountered by the machine on its next round about the field, very frequently clog the knives. When this occurs, the farmer has to stop his team and pull the clogged grass out with his hands. This, of course, results in a loss of time and is very annoying.

The object of the present invention is to provide a rod which will press down all the cut grass, hay or the like out of the way of the cutter bar, so that clogging will be impossible.

This object is attained by providing a rod secured loosely to the inner shoe of the cutter bar and to the underside of the tongue of the mower. This rod is so shaped as to be out of the way of the horses heels, and at the same time cannot catch in cut hay, but instead, will press the same down under the inner shoe or cutter bar as the machine goes forward.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing,

Figure 1 is a perspective view of so much of a known type of mower as is necessary for an understanding of the inventiomwith the attachment in place.

Fig. 2 is a sectional View of a portion of the inner shoe showing its attachment with the rod which forms the present invention.

tion of the rod with the tongue of the machine.

Fig. 4 is a top plan view of the rod by itself in the position of Fig. 1.

5 represents a tongue of a well known type of mowing machine, and 6 the inner shoe thereof. .A rod 7 is secured to this tongue and shoe, but not rigidly.

The rod 7 is bent upwardly, as indicated at 8, near one end thereof and is further given the bends designated at 9 and 10 intermediate its ends, the bend 9 being inwardly toward the tongue, and the bend 10 being forwardly, the extreme outer end of the rod being connected to the tongue in advance of the connection of the draft devices thereto. These three bends together provide for such a disposition of the rod as will cause it to incline upwardly from the inner shoe and toward the tongue and yet will not interfere with the whiflietree, will be out of the way of the horses heels, and will press down all bunches of cut grass under the shoe or cutter bar as the machine goes forward, so that clogging will not occur.

The connection of the rod to the inner .shoe, as illustrated in Fig. 2, is a loose one.

The shoe end of the rod is straight and has screw threads 11, and spaced therefrom an annular shoulder 12. The shoe has the customary hole therein for the attachment of the usual short rod which is provided with all mowers. Such a hole is shown in the patent to Dain No. 921955. This hole or bore provided on the point or toe of the inner shoe is taken advantage of by running the bent end 8 of the rod therethrough, with the shoulder 12 on the forward side, and a nut 13 screwed down upon the screw threads 11. When this has been done, there will be a loo-seness or play between the base of the nut, the shoe, and the shoulder, so that the shoe may turn relatively to the rod when it is elevated as in driving the machine along a road or the like. This looseness or play will also permit of the cutter bar being turned to out high or low in the fields.

The forward end of the rod is slidably secured to the underside of the tongue by means of a clip 14, fastened in any desirable way to the tongue. The rod can slide freely between the clip and the underside of the tongue. This construction is necessary because when rough ground is encountered there will be con iderable vibration of the tongue and also of the cutter bar,.and the rod would be bent out of shape in a short time unless loosely held to the tongue.

As the machine advances through the field, the heavy bunches of cut hay are moved out of the way of the inner shoe instead of being caught thereby and forced into the cutter bar in a wad. The rod. when shaped as described, in no way inter feres with the whifiietree and is entirely out of the way of the draft animals. Its loose connection at each end of especial importance because it permits the operation of the machine without any interference what ever therewith and yet will positively pre vent clogging of the knives, as has been described.

What is claimed is 1. In a mowing machine having a cutter bar provided with an inner shoe, the combination therewith, of a rod secured loosely at one end directly. to said inner shoe and slidably secured near its outer end to the tongue of the machine, said rod being bent from its connection with the shoe first upwardly, then inwardly toward the tongue and then forwardly beyond the connection of. the draft devices to the tongue, whereby .the rod is at all times clear of the heels of the draft animal.

2. In a mowing machine having a cutter bar provided with an inner shoe, the combination therewith, of a rod, having one end straight and passed through a hole in the shoe, means for securing said rod therein so as to allow relative movement of said rod and shoe, said rod being bent, in advance of its connection with the shoe, in an upward. direction, then bent laterally toward the tongue, and then forwardly to a point in advance of the connection of the draft devices to the tongue whereby the rod is at all times clear of the heels of the draft animal, and means for loosely connecting the forward end of the rod to the underside of the tongue.

In testimony that I claim the foregoing as my own, I have hereto alfixed my signature in the presence of two witnesses.

ROBERT W. WALLACE.
