SIGKLE-GUARD MOWERS OR HARVESTERS.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed June 21, 1906. Serial No. 322,664.

To all whom it may concern:

Be it known that 1, WILLIAM GATERMAN, a citizen of the United States, residing at Manitowoc, county of Manitowoc, and State of Wisconsin, have invented new and useful Improvements in SickleGuards for Mowers or Harvesters, of which the following is a specification.

My invention relates to improvements in sickle guards for mowers or harvesters.

The object of my invention is to provide a form of construction in which the sickle guard will perform the three-fold function of a shear plate, a guard for the sickle and means for picking up lodged vegetation, so that it will be cut by the sickle knives.

In the following description reference is had to the accompanying drawings in which,-

Figure 1 is a side view of my invention. Fig. 2 is a side view of the sickle receiving member. Fig. 3 is a top view of the same. Fig. 41 is a sectional view, drawn on line :t.r of Fig. 1. 7

Like parts are identified by the same reference characters throughout the several views.

The sickle guard is formed with a sickle receiving member having a fiat surface 1 secured to the finger bar A in the usual manner and from which the guard proper extends forwardly and is provided with the usual laterally projecting arms 2. A finger 3 is provided with a guard arm or shield 4,

. which projects rearwardly over the sickle sections when the latter are in position. The front end of the finger 3 is preferably provided with substantially straight sides at 5 and a tapered extremity at 6. A bolt receiving aperture 7 extends laterally through the straight sided portion 5, and the upper surface of the finger immediately in advance of the guard arm 1, is provided with a socket 8, as clearly illustrated in Fig. 3. The under surface 9 of the finger near its forward end is curved upwardly and forwardly to a point near the extremity, the upward curve being most pronounced in the rear of and under the bolt hole 7. The extremity of this finger is adapted to fit a socket 10 in the rear of a shoe 11, which constitutes the outer member of the guard. The socket is of sufiicient size to receive the end of the finger to a point near the arm 4, and a bolt 12 extends transversely through the rear end portion of the shoe and through the bolt hole 7 in the finger, thus connecting the shoe and finger together. The under surface of the shoe near the rear end is substantially in the same horizontal plane as the under surface of the rear portion of the finger, and the forward eX- tremity of the shoe is tapered and rounded upwardly as illustrated at 13 in Fig. 1. The upper surface of the shoe extends diagonally, rearwardly and upwardly, terminating in an arm 14 substantially above the knife guarding arm 4, and a spring 15 mounted in a socket in the rear portion of the shoe is interposed between the arm 14 and the finger and is engaged in the aperture 8, whereby the rear end of the shoe is lifted resiliently and he point depressed into close contact with the surface of the ground.

With the described construction, the shoes will be free to oscillate in traveling over the uneven surface of the ground, but will be held with sufficient rigidity against lateral movement, owing to the fact that the sides of the finger near the bolt receiving apertures are substantially straight and are engaged between substantially straight side walls of the socket 10 in the shoe.

lVith the described construction the shoe may be removed if desired, and the sickle receiving member used alone, if the nature of the ground or the character of the vegetation is such as to make the use of the shoe inexpedient.

Various modifications in the construction of the sickle guard as well as in the form and arrangement of parts, will suggest them selves to the ordinary mechanic and may be incorporated without departing from the scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

1. A sickle guard for mowers and harvesters having an intermediate joint and provided with a rearwardly projecting guard arm for the sickle connected with the rear member in the rear of the joint, the forward member having a socket in its rear end and the rear member having a forwardly projecting ointed end, loosely engaged in the socket in t 1e forward member,said rear member being adapted to be used separately.

2. A knife guard for a mower or harvester having a forwardly extending finger provided with a pointed end, and having an a erture extending transversely there: Initestimony-wheredf.Iafiiymysignature t rough in the rear of the p0int(,1 1ancfl asiclfie inthe presence of tWo Witnesses.
