IMPROVEMENT IN MOWlNG-MACHINES.

Specification forming part of Letters Patent No. 13,517, dated September 4, 1855.

To all whom it may concern:

Be it known that I, COLLINS B. BROWN, of Alton, in the county of Madison and State of Illinois, have invented a new and Improved Mowing-Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making 'a part of this specification, in which Figure l is a side view of my improvement. Fig. 2 is a plan or top view of the same. Fig. 3 is a detached sectional view of a portion of the finger-bar and main bar of the machine, showing the way in which they are connected together,wx, Fig.2, showingthe plane of section.

Similar letters of reference indicate correspondin g parts in the several figures.

The nature of my invention consists, first, in a peculiar way of attaching the finger-bar to the main bar of the machine; second, in the peculiar construction of the frame of the machine.

To enable others skilled in the art to make and use my invention, I will proceed to describe'it.

A represents the driving-wheel, the inner side of the rim of which is provided with cogs or teeth a, as shown in Figs. 1 and 2. The axle of the driving-wheel works in bearings c c on an inclined metallic frame, B, to the upper part of which the drivers seat 0 is attached. The frame B is formed of two wrought-iron side pieces, (I d, the upper ends ofwhich are secured to the seat 0, and the lower ends are attached. to a flat bar, D,,of wood, which projects from the side pieces, (Z d, at right angles, as shown clearly in Fig. 2.

To the under side of the bar D there are attached metallicstrips e 6, one of which is shown in Fig. 1. These strips are connected at their upper ends to the side pieces, (I d, underneath the bearings c c of the axle of the driving-wheel A. The inner side piece, (1, and strip 6 project some distance beyond the bar D, and have the draft pole or tongue E secured between them by bolts ff. The draft pole or tongue is also secured by a brace, g, to the bar D.

F is the finger-bar, constructed of wood and provided with fingers h, in which the sickle G works. The fingers and sickle may be of usual construction, and therefore require no particular description.

The inner end of the finger-bar F is secured to the end of the bar D in the following manner: Two metallic p1ates,i t', are placed at each side of the ends of the finger-bar F and bar D, the ends of the two bars overlapping each other, as clearly shown in Fig. 3. The two plates are bound or pressed firmly against the sides ofthe two bars by screw-bolts jj, which pass between-the two bars and fit in recesses therein, and screws or screw-bolts 7t 7t pass vertically through the ends of the two bars, as shown clearly in Fig. 3.

H is a shaft, one end of which works in a bearing, 1, on the inner side piece, at, and the opposite end works in a bearing, m, on the upper part of an upright, n, attached to the bar D.

On the shaft H there is placed a pinion, 0, which gears into the cogs on the driving-wheel A, and I is a toothed-wheel at the outer end of the shaft H. The toothed-wheel I gears into a pinion, J, which is placed upon a small shaft, K, having a crank, L, at one end. This shaft K works in bearings 11 10, one of which is on the upright n, and the other is attached to the inner side piece, d.

M is a connecting-rod, one end of which is secured to the crank L, and the opposite end is attached to the sickle Gr.

By arranging the gearing as herein shown-- viz.,' having the wheel I and pinions J 0 near the driving-wheel-the gearing is protected from the cut grass, straw, and dirt, and the machine is rendered compact. By constructing the frame B oftwo metallic side pieces, (I d, and attaching the bar D and draft-pole t0 the lower end of the frame B a strong durable framing isobtaiued, and one extremely simple and economical to manufacture. By securing the finger-bar to the bar D by means of the plates t 2 bolts j and screws la k, as herein shown, the finger-bar is firmly attached to the bar D and prevented from working loose, as the bolts jjprevent any lateral play or movement of the finger-bar, and the screws k prevent vertical play or movement.

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

1. Attaching the finger-bar F to the bar D of the frame by means of the plates t i, placed at each side of the two bars near their ends, which overlap each other, the plates being bound or pressed against the sides of the bars the bar D to the lower ends of said side pieces, by means of screw-bolts j j, which pass beand also the draft pole or tongue E, substantween the two bars, the ends of the bars havtially as herein shown and described.

ing; screws or screw-bolts k 7c passing vertically COLLINS B. BROWN. through them, as herein shown and described. Witnesses:

2. Constructing the frame of the machine of BENJ. F. SARGENT, two metallic side pieces, 01 d, between which M. H. FILLEY,

the driving-wheel A is placed, and attaching J. I. JOHNSON.
