UNITED EDWARD LAAS, OF CHICAGO, ILLINOIS.

WEED-CUTTER.

Specification of Letters Patent; Patented 113,1. 1,1910.

Application filed January 29, 1907. Serial No. 354,776.

Be it known that I, Ei wARo LAAS, a citi zeiiof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvement-s in Weed-Gutters, of which the following is a specification.

My invention relates to devices which are especially intended and adapted for use in cutting, uprootiiig and destroying weeds on the railway right of way. The device might, however, be readily adapted to other uses.

More particularly the invention has for its object to provide a device which may be readily attached to an ordinary railway car or other suitable vehicle, and which shall be economical in construction, easily operated and readily adjustable to meet difierent roadbed requirements. This and such other objects as may hereafter appear are attained by my invention,convenient embodiments of which an: illustrated in the accompanying drawings, in which,

Figure l is a. plan view of a portion of an ordinary push car with the devices of my invention attached thereto. Fig. 2 is an end elevation of the same. Fig. 3 is a longitudinal section through one of the cutting devices. Fig. .4 is a perspective view of a mov-' able mounting bracket. Fig. 5 is a perspective view of the pivoted shaft hanger; and Nig. 6 is a vertical section through the movable bracketwith the hanger in place.

' two in number.

Like numerals of reference indicate the same parts in the several figures of the drawin s.

l teferring to the drawing, the roadbed is represented by the numeral 1.

2 is a push car of ordinary construction runnin on the

rails

3, 3, and 4, 4 represent generally the cutting devices here shown as These cutting devices are suitably supported from the car and are adapted to rest freely upon the ground and to liavesufficient verticalmotion so they will ride over the inequalities thereof.

The cutters may be'of any desired construction. A preferred form is shown in detail in Fig. The cutter here consists of -a shaft 5 and a number of disks 6, which are preferably dish-shaped in the manner of the' ordinary disk harrow and separated by suitable spacers. The spacers here serve three purposes: first, to separate the disks, second, to supply suflicient weight to carry the disks into the ground, and third, to limit the depth of the cut. The spacers consist of central webs 7 provided with flanges 8 engaging with adjacent disks. The disks and spacers may be held upon the shaft by the collar 8 at one end and the nut 9 at the other.

The cutters are mounted on the car in such a way that their angular position may be varied at will, and also so that they may have free vertical movement. In my preferred manner of mounting the cutters, 1 provide brackets 10 secured to the side of the car and braced by the longitudinal brace 11, to which they may be secured by bolts 12. Each of these brackets has a collar 13, the portion above the collar forming a bearing for a swiveled bracket 14. The latter consists of two angle plates suitably secured together forming a bearing surrounding-the end of the stationary bracket and terminating in two

arms

15, 15 having slots 16. These arms are spaced by the spacer 17. Pivoted in the space between the arms 15 is a-hangei" 18,

.- having a bearing 12) to receive the end of the cutter shaft fi, this shaft having a boss 20, the hanger being held against the boss by a nut 21. The hanger turns upon a bolt 22 havin reduced ends, as shown in Fig. 6, exten ing through slots 16, whereby the hanger is capable of vertical adjustment on thebracket.

NVhen more than one cutter is used, I prefer tocouple the cutters together in such a way as to -allow them independent, vertical movement and, to this end, on the shafts 5 are rovided'the blocks 23, which are loose and lield in position by

pins

24, 24. On these blocks are pivoted arms'25, the adjacent ends of the arms being connected by the connecting rod 26, on the ends of which are rings or loopsextending through perforations in the arms. At each end of'the "car is a sliding beam 27 supported by stirrups 28 and from one or the other of these beams, according to the direction in which the car is running, a.

chain 29 extends to the arm on the adjacent cutter. By this means the horizontal swing of the cutters may be limited to any des re an 1e.

Vhen it isdesired to raise the cutters to avoid fences, cattle guards or other obstructions, or for any other purpose, this may be done through the capacity of the hangers to turn on their pivots. Any suitable hoisting device may be utilized; for example, I have shown a crab mounted on uprights 30 and consisting of a shaft 31 provided with a crank 32, a ratchet 33and a do 34. A chain rod, winds upon the shaft 31.

desired manner.

I wish it to be understood that I do not desire to be limited to the exact devices, and arrangements shown and described, as obvious modifications will occur to persons skilled in the art.

The operation of my device is as follows: The car is propelled along the track in any the cutters preferably standing at an obli ue angle to the car. The hangers will be adjusted Vertically to bring the cutters to a proper height. The cutters will now be lowered until they run along freely on. the ground beside the track, their weig t being sufiicient to carry them a proper distance into the ground. The coin nections between the outer ends of the cutters are flexible connections and, therefore, the cutters will be perfectly free to move vertically and so will follow the inequalities of the round over which they pass. The disks Wlll, of course, cut and destroy the Weeds or other growth over which they pass. When an obstruction comes in sight, the operator will raise the free ends of the cutters by means of the crab, the beam to which the cutters areattached sliding inward toward the car, so that it clears the obstruction as well as the cutter.
