CUTTENG APPARATUS FOR MOWERS.

SPECIFICATION forming part of Letters Patent No. 360,374, ted March 29, 1887.

Application filed January 5, 1884. Serial No. 116,510. (No model.)

To all whom, it may concern:

Beit known that l, \VILLARD E. CLOUGH, a citizen of the United States, residing at Concord, in the county of Merrimac and Stateot New Hampshire, have invented certain new and useful Improvements in the Cutting Apparatus for Mowers; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to mowing and analogous machines, and has for its object to construct a cutting apparatus for machines of the kind mentioned, in which at no time will all the knives be idle nor at work, but different knives will be at work at different times.

I accomplish the object mentioned by the construction, combination, and relationship of parts hereinafter described, so that others skilled in the art may be able to make and use the same, reference being had. to the accompanying drawings, and to the letters of refer ence marked thereon, forming a part of this specification, theinvention being particularly pointed out and distinctly claimed at the end of the description of its construction and operation.

Of the drawings, Figure 1 is a plan view of the cutting apparatus, showing the relative position of the knives and guard-fingers when the former are at one extreme limit of their reciprocal movement. Fig. 2 is also a plan View of the same, in which the knives are shown to have traveled to a point which is equal to half their entire stroke. Fig. 3 is a like view showing the knives in the extreme limit of their reciprocal movement opposite to thatin which they are represented in Fig. 1.

Similar letters of reference indicate similar parts in all of the figures.

A represents the guard or finger bar, andB the guard-fingers. C is the cutter-bar, and D represents the knives,which are riveted in the usual manner to said cutter-bar. E is a section or portion of a pitman-rod, and E the inner shoe.

In the drawings the machine is represented as provided with fourteen guard-fingers,B, and fifteen knives D, and in Fig. l the first knife (1) is hidden in the inner shoe, E, located equally distant from the first guard-finger (1) as are the guard-fingers from each other,while the fifteenth knife (15) is exactly within the center of the thirteenth guard -finger (13), which brings the eighth knife (8) midway between the sixth and seventh guard-fingers, 5 5 (6 and 7 v In Fig. 2 the pitman-rod E has made half of its stroke, by which it will be seen that the eighth knife has reached the center of the seventh guard-finger, while the first knife has moved from the position shown, Fig. 1, halfway to the first guard-finger, and the fifteenth knife has reached a position midway between the thirteenth and fourteenth guard-fingers.

In Fig. 3 the pitman-rod E is represented as havingcompleted its stroke and brought the knives to the extreme limit of their movement opposite that in which they are represented in Fig. 1, so that the tip or point of that knife I will be brought substantially in line with the tip of its corresponding guardfinger 1, and the center knife, 8, substantially midway between the two guard-fingers 7 and 8, nearest the center of the series of guardfingers,while the tip or point of the fifteenth knife will have reached a position substantially in line with the tip of the fourteenth guard-finger. Oonsequentlyin the operation of the machine all of the knives are not cut-ting at the same time, nor are all idle, as in mow- 8o ingmachines of common construction; but different knives will be at a work at different times.

It will be seen that by my improvements a continuously-cutting apparatus is provided in 8 5 which the power or force required to operate the knives is even at all times, for at no time will all the knives be idle nor all at work, and the same number of knives will be at work at all times.

Having thus described my invention, what I claim is- In a cutting apparatus for inowingmachines, the combination, with the fiugerbar provided with a plurality ofguard-fingers ar- 5 ranged equidistant from each other, of a cutter-bar provided with knives one more in number than the number of fingers on the fingerbar, and also arranged equidistant from each the center knife shall be exactly midway beother, the construction and arrangement of tween the two guard-fingers nearest the center 10 the guard-fingers and knives being such that of said finger-bar, all as and for the purposes the distance from point to point of the former hereinbefore set forth.

5 will be slightly greater than the distance from WILLARD E. CLOUGH.

point to point of thelatter, and that when the \Vitnesses: point of either end knife shall be exactly in J. B. THURSTON,

line with the tip of either end guard-finger VVM. M. CHASE.
