JESSE S. LAKE AND DAVID LAKE, OF SMITHS LANDING, NEW JERSEY,

' ASSIGNRS TO JAMES A. SAXTON.

IM PROVEM ENT IN GRASS-HARVESTERS.

Specitication forming part of Letters Patent No. 9,137, dated July 20, 1852; Reissue No. 1,ll6, dated January 1, 1861.

To all whom it may concern: Be it known that We, JESSE S. LAKE. and DAVID LAKE, both of Smiths Landing, in the county of Atlantic and State of New Jersey, have invented certain-new and useful Improvements in MoWing-Machines or Grass-Harvesters; and we do hereby declare that thefollowing is a clear, full, and exact description ofthe same, reference being had to the accompanying drawings, forming a part of this speciiication, and in which- Figure 1 represents a plan view of a machine, showing one mode of applying our said improvements. Fig. 2 represents a side view of the machine as shown in Fig. 1, looking in the direction of arrow l, the machine being represented as reversed, or facing in an opposite direction from Fig. 1. Fig. 3 represents a portion of the frame, wheels, and cutting apparat-us, looking in the direction of arrow 2, Fig. 1. Fig. 4 represents a longitudinal section on line A B, Fig. l, the cutting apparatus being shown in two differentpositions-one in black lines and the other invred. Fig. 5 represents a cross-section on line C D, Fig. l, looking in the direction of arrow 2, the parts G and F being shown in different positions in Tull and dotted red lines. Figs. 6 and 7 represent detached parts of the mechanism used to operate the cutting apparatus.

Whenever it may be expedient to use one or more of the several parts or branches ot our improvements separate from the rest, such part or parts may be used in connection with any suitable frame and gearing; and it is obvious that several parts of our improvements areV the advantages of a single drive-Wheel and a leading swivel-wheel so arranged in relation to the main frame as to run on a line just outside of the standing grass.

That bran ch of our said improvements whichV is the subject of this patent is designed to accom plish the above advantages.

The accompanying drawings represent a 'mowing-machine with our said improvements applied thereto but we do not deem a detailed description of all'the various parts here necessary, since they are fully described in other reissue patents to us of even date herewith,

/ and ofwhich this is one division.

piece, A', is fastened to the under side of the vfront of the main frameA, having a lip or projection, as shown in dotted lines, Fig. 1, so

that the rear circular part of the swivel-frame B turns under the front of frame A and over the lip or projection of A'". rlhe rear of frame A is supported by two wheels, C C', on a common axle, C, which 'passes through the .lower ends of the pieces vB B, which are rigidly connected to the rear of the main frame, and are also united at bottom by piece A. Wheels C C are arranged on the outside of frame A, wheel AC being loose on shaft or axle C",while Wheel C is made fast thereto.

The finger-support plati'orm or frame G, to the frontof which are attached the guards or fingers b, is sustained by a metallic connection or lever, H, which passes loosely through a sliding piece, I, thenceloosel y through ahin ged guide device, c J J, and has an adjustable weight, d, on its end. The upper inner part of Gr is grooved out and vprovided lWith a fric.- tion device consisting of a ring, e, withy radiating loose shafts, on the ends of which are wheels e', whereby the part F, to which .the cutters are attached, can he rotated around the pivot g, fast in Gr, without undue friction. The friction device is free to run around. .The part F is connected to the shaft h of pulleyK by a series of jointed levers and-swivel or hinged rings, the latter being placed between ears or lugs h h h h', so that as the machine advances motion is communicated from gear D on wheel O to gear E and pul'ley K, and thence by band j to pulley K, and as thelatter revolves arapid rotary motion is communicated to the jointed levers fi t' t" t" and frame F, and the grass is cut by the cutters a whileitis held up by the guardfingers b.

In the use ofmowingmachines there is great strain upon the joints. Therefore a triangular frame will stand a much greater strain without yielding than a rectangular one, owing to the fact that the parts brace each other, and we vhave availed ourselves of this advantage, while at the same time wehave made an important improvement,in that we have arranged or placed our main driving-wheel on the outside of the triangular frame, thus enabling the frame to be made much narrower, While at the same time the wheel is in a position where it can be examined or repaired in a more expedi tions manner than if placed on'the inside of the frame. Then, again, in those machines'in which a triangular frame is used and the main drive-wheel is placed on 4the inside of the frame that portion which is on the outside of the wheel is constantly liable to strike against obstructions, which is not the case with our invention. ever, in having the main drive-wheel placed on the outside of the frame-viz., the Weight of the cutting apparatus and frame was tooV far to the grassward to bear with proper and sufficient weight upon the drive-wheel to cause it to operate the cutters. 'To remedy this defect without adding to the actual weight to be drawn by the team induced us to combine with a triangular main frame a lever-seat for. the

driver, which should extend out over the main drive-wheel, so that the driver by moving out on said seat could cause the weight ofthe cutting apparatus and frame to be nearly balanced on the driving-wheel, although said wheel'was placed on the outside of the triangular frame.

The drawings show a lever-seat, M, extending out over the drive-wheel C. This seat has a fulcrum at lc, and is passed under a roller in the end of the sliding coupling-piece I, which supports the cutting apparatus.

To relieve the necks of the horses we pro- We found a disadvantage, howvide the front ofthe frame with a swivel frame and wheel, B' B, the team being attached to frame B in any suitable manner. By the use of the swivel-wheel B" and fra-me B' the machine can be turned much easier and with far less danger of wrenching the machine or of upsetting it than if the horses were attached directly to the front of the frame.

As the main drive-wheel U and swivel-wheel B are arranged and combined with the triangular frame they run just outside of the standing grass and in nearly a line with each other. Oonsequen'tlythemachineisnotexposed to more obstructions by the use of the swivelwheel, nor is the swivel-wheel liable to get clogged up by the grass cut by the previous swath, since it runs on the ground which has been previously cleared by the action of the machine. y

Having described one practical way in which that branch of our invention which forms the subject ot' this patent can becarried out, we wish it to be understood that we do not contine ourselves to a .machine in which any particular cuttingfapparatus can be used; but

What we claim as our invention, and desire to secure by Letters Patent, is

1. Placing the driving-wheel in a mowingmachine on the outside of the frame, in coinbination with a triangular-shaped frame on the inside ot' the wheel.

2. In a mowing-machine, the combinatlon of the following elements, viz.: a triangular main frame, a single driving-wheel arranged ou the outside of said frame, and a hinged lever-seatofor the driver, for the purposes set forth.

3. In combination with the main frame ot' a mowing-machine, la single drive-wheel and a leading swivel-wheel so arranged in relation to each other and the cutting apparatus as that the said wheels shall run on 4lines just outside of the grass to be cut.

In witness whereof we havehereunto subscribed our names.
