DEVICE FOR LINING CUTTER-BARS.

SIECIFIGATION forming part of Letters Patent No. '741,655,1dated October 20, 1903;v Application led April 7, 1902. Serial No. 101,676. (No model.)

To all whom it may concern:

Be it known that I, JOHN GEIGER, residing at Minden, in the county of Pottawattamie and State of Iowa, have invented certain useful Improvements in Devices for Lining Cutter-Bars; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and novel improvement in cutter-bar adjustments.

The object of my invention is to provide a means and mechanism whereby the outer end of the cutter-bar of a mowing-machine may be brought into alinement with the pitmanbar, as will be described more fully hereinafter.

In the accompanyingdrawings I have shown Fig. 3 shows an enlarged sectional detail, disclosing the alinement of the adjusting mechanism. Fig. 4 shows Va sectionalview with portions removed, disclosing the method oflocking the key in position. Fig. 5 shows a detached detail of the eccentric-pin used vin my invention. tail of the key employed in my invention.

It is a well-known fact that owing to the length of the cutter-bar of a mowing-machine and because of the wear incidentto vthis extended cutter-bar coming in contact with obstructions the outer end of the cutter-bar is apt to wear itself out of alinement with the pitman-bar secured to the cutter-bar, so kthat there is a strain upon this moving cutter-bar preventing the mowing-machine working to its fullestcapacity. In order to provide a means whereby the knife-bar and the fingerbar may always be kept in direct alinement with the pitman, I provide the shoe 1 with the upwardly-extending ears 2 2'. Through the rearward ear 2 extends a simple bolt 14, as shown in Figs. 1

and 2, secured by a Cotter-pin o, and this bolt 14 secures the ear b of the yoke 12, as shown Fig. 6 shows a detached dein Fig. 2. To the forward ear 2, however, of the shoe 1 I secure an eccentric-pin A, which passes through a suitable opening of this ear 2, as shown in Fig. 4, and this eccentricpin A is provided with astem 17, ecoentrically positioned within the ear l) of the yoke 12, as is clearly shown in Fig. 5. pin portion 15 is provided with a serrated collar 16, as clearly disclosed. The yoke 12, from which extends the usual pitman 13, is secured to the shoe 1 by means of the bolt 14 and stem 17, as disclosed in Figs..1 and 2, the stem 17 projecting from the pin A, as shown in Fig. 3. Secured to this shoe 1 is the usual ngerbar 6, provided with the iingers 7 within which slides the usual cutter-bar V4, provided with the usual plates 5, and to this cutter-bar 4 is secured the holder 8 by means ofthe bolts o, and this holder is provided with the bolt 9, from which extends the pitman-bar 10.

In order to bring the cutter-bar 4 in alinement with the pitman-bar 10, it is simply nec- Intermediately the essary to apply a' wrench to the head of the eccentric-pin A and turn the same either to the right or left until the bar is in true alinement with the pitman-rod. The eccentric movement of the pin 17 will of course rock the 'shoe 1 to the right or left' relative to the yoke l2. To lock the eccentric-pin in proper position after the same has been adjusted, I provide the ear2 adjacent the pinopeningwith an .L-shaped slot 1 8, as shown `in'Fig. 4, into which fits a serrated-jawed L- shaped wedge provided with the head 20 and the'serrated j aw f and the extending threaded stem 21. This serrated jaw f is adapted to come in engagement with the serrated collar 16.0f the eccentric-pin A, and in. order to lock this wedge I provide` the nut 23, which is secured to the stem 21, so securely locks the eccentric-pin with the forward ear 2. Now when the cutter-bar works out of alinem'ent with the pitman the operator releases the nut 23, hammers back the wedge 2O to throw it out of engagement with the eccentric-pin,

and then again adjusts the eccentric-pin, so 'that the cutter-bar and pitman-bar again come in alinement.

This device can be easily attached to a mowing-machine, and

Having thus described my said invention,

what I desire to secure by United States Letters Patent is l. The combination with a shoe of a mowing-maohine,of two upwardly-extending ears, a pin positioned within the rear ear, an eooentric-pin positioned within the forward ear, said eccentric-pin being provided with a serrated collar, and a wedge provided 4with the serrated face adapted to come in contact with aforesaid serrated collar, as and for the purpose set forth.

2. The combination with the shoe of a mowing-machine, of a rearwardly-positioned ear, a pin within said rearwardly-positioned ear, a forward ear, a pin within said forward ear provided with a serrated collar and a ey- JOHN GEIGER. Witnesses:
