IMPRovED HEDGE-TRIMMING DEVICE.

Specification forming part of Letters Patent No. 36,420, dated September 9, 1862.

To a/ZZ whom, it may concern:

Be it known that I, T. AV. NICHOLS, of Olena, in the county of Henderson and State of Illinois, have invented a new and Improved dImplement or Device for Trimming Hedges;

and I do hereby declare that the following is a full, clear, and exact description of the same,

` reference being had to the accompanying drawings, making a part of this specification, in whichh Figure l is a side sectional' view of my inf vention, taken in the line x x, Fig. 2. Fig. 2

is a plan or top view of the same.

Similar letters of reference indicate correspending parts in the two figures.

v The object of this invention is to obtain a machine by which hedges may be trimmed at the top horizontally, and at eachv side perpen- `rro enablethose Skinefrin the art to fully understand and construct my invention, Iwil proceed to describe it. A represents a frame, which is mounted on4 one large wheel, B, and 'two caster-wheels, C C, the former being at the right-hand side of the frame and the latter at the left-hand side.

D is the draft-pole, and E the drivers seat. The. large wheel B is the driving-wheel of the machine, and it hasatoothed rim,E, attached concentricallyto its inner side, into which a pinion, F, gears, said pinion being on a small shaft, a, on which a toothed wheel, G, is placed.

The wheel G gears into a` pinion, H, which is on one end of a shaft, I, that is placed horizontally on the upper part of the frame A,`and has a iiy-wheel, J, uponit, and also a cylinder, K, formed of two circular disks, b b, connected at their peripheries by knives c, a proper number of the latterbeing used. To each disk b there yis also attached radially a knife, d. These knives may be in the same planesasthe' disks b b, or be bent slightly outward from them. (See Fig. 2, in which the outward position of the knives are shown in red outline and shown in the same planes with the disks in tint.) The cylinder K is at the left side of the frame A, and as the machine is drawn along at the side of the hedge the knives c will trim or cut its upper surface horizontally, while the knives d will trim or cut the upper part of both sides,either vertically or inclined, according to the position of the knives d. 'The trimming is done at one operation and-very rapidly, or as fast as the machine is drawn along, the team of course walking moderately. The caster-wheels C C admit of the machine being very readily turned.

It will be seen that the portion of the frame A which supports the shaft I of the cutting-y cylinder K should be sufliciently high to admit of the knives working at the top ypart of vthe hedge.

The machine may be constructed at a moderate cost, and will save a vast amount of labor vin trimming hedges and perform the work in a much more even and perfect manner than \it can be done by hand.

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

The horizontal knives c of cylinderK for T. V. NIGHOLLS. Witnesses: v
