JAMES PINE, or TROY, NEW YORK.

IMPROVEMENT IN MOWINGHMACHINES.

Specification forming part of Letters Patent No. 44,655, dated October 11, 1864; reissue No. 7,344, dated October 10, 1876; application filed July 3, 1874.

To all whom it may concern.-

Be it known that I, JAMES PINE, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Mowing-Machines. I do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making part of this specification, in which Figure l is a side sectional view of my machine, taken in the line 4 4, Fig. 2. Fig. 2 is a top view of the machine. Figs. 3 and 4c are views of the shoe and plate for adjusting the track-clearer. Figs. 5 and 6 are sectional details.

Similar letters of reference indicate corre sponding parts in the several figures.

This invention relates to a new and useful improvement in adjusting or raising and lowering the finger-bar, and the parts connected therewith, to wit, the brace-rod and trackclearer. It also relates to an improved draft attachment for keeping the finger-bar free from the surface of the ground. Also, to an improved means for connecting the working parts with the axle of two transporting wheels, which wheels are both driving-wheels, whereby nuts and bolts, and all their attending disadvantages, are avoided.

The main objects of my invention are to obtain a mowing-machine which will have a light draft,which can be economically manufactured, and which will admit of having its finger-bar raised and lowered vertically, and with but a limited movement of the lever employed for this purpose. Also, to obtain a track-clearer which can be adjusted so as to have a more or less oblique position to the line of draft, as circumstances may require; and, finally, to construct a gear or supporting frame in one piece, and to support and keep it in position on the axle by passing the latter through a hole or opening in said frame, all as will be hereinafter explained.

In the accompanying drawings, A designates the axle of the machine, on which axle two transporting or driving wheels, B B, are applied loosely, they being connected to the axle when moving forward by means of pawls and ratchets arranged in the usual way. To.

the axle A is firmly keyed a toothed wheel, 0,

from which motion is communicated to the sickle-driving mechanism through the medium of intermediate gearing. This gearing consists of wheels at a M. The wheels a a are applied to, and supported by, a short stud or pivot, on which they rotate, and are provided with a clutching device, a actuated by a hand-lever. The wheel a is keyed on a crankshaft, T, which is at right angles to the axle A, and which is prevented from becoming entangled with .grass by its being partially surrounded by the arm E of main frame, which arm E of main frame projects in front of axle A. This crank-shaft is designed for giving motion to the sickle. 'The arms E and F J constitute the sides of the frame, through which is a tube or opening or hole, through which the axle A passes, on and by which said gear-frame is supported and kept in position. The arms E and F J are connected by tube 1), and are constructed or cast in one piece therewith, constituting the gearframe of the machine, thus dispensing with the use of bolts and nuts. To the front end of the arm E of the gear-frame a bar, G, is connected by a joint, 3, and this bar G is braced by a rod, 11, the end of which is at tached to G by a swiveljoint, I, which is formed by a joint, 0, connected by a swivel, d, to a plate, 0, on G, as clearly shown in Figs. 1 and 2.v The back end of the brace H is provided'with a fork, f, through which a pin, 9, passes, said fork receiving the curved arm J, which extends back from the sleeve D, and which has a curved slot, g, through it for the pin 9 to pass through; The back part of the brace H is also suspended from the arm or side J of the frame by means of a swinging pendant, a. (Shown clearly in Fig. 1.) The arm F is in line with the arm J, and constitutes one side of the gear-frame, and the arm F has a vertical slot, 11, longitudinally through it, and it also has a longitudinal horizontal slot, j, through it. In the vertical slot"; awheel or pulley, K, is fitted, its axis 70 beingin the horizontal slot j. This wheel or pulley has a lever, Ii, attached to it, and extending upward any suitable height. At the front end of side F J of gear-frame is a small pulley, 2, having grooved periphery, which pulley rotates on its axis vertically in a slot in said side of frame.

To the pulley K on the under side at the periph'ery which is grooved is attached a cord or chain, which is also attachedin rear otsaid pulley K to the arm F J. A cord or chain is also connected with pulley K at its periphery at the upper side, and extends from thence, passing over small pulley 2, and connects with bar G. The finger-bar M is connected with bar G by means of joint 1. Said finger-baris provided with a shoe, N, near thejoint l, said shoe constituting a part of said joint Z. From the above description it will be seen that by a limited movement of the lever L, the bar G and fin ger-bar M will be raised, for the reason that the wheel or pulley K, to which the said lever is attached, has two motions, to wit: a rotary one and a sliding one, the latter being obtained in consequence of the axis is sliding I in the horizontal slot j. This limited movement greatly facilitates the raising and lowering of the finger-bar, and it will be seen that, in consequence of the brace-rod H being attached to the bar G' and arm J, as shown, the bar G and finger-bar M are allowed to rise and descend in a vertical plane, and, consequently, with but little friction, and without subjecting either the rod H or bar G to any unnecessary friction, the rod H being allowed a certain amount of longitudinal play on account of its back end working in the curved slotg in the arm J, and the swivel-joint Iformingaflexible connection between the rod H and bar G. The side E of the gear-frame, and the bar G attached to the front end thereof at right angles, and the rod H attached to the bar G at, or nearly at, right angles therewith, constitute a second or under frame that supports and keeps in position the finger-bar M. 0 is the draft-pole, which is attached directly to the tube D. P designates a draft-lever of a right angular form, and attached to the draftpole O by afulcrum-pin, a the upper part or arm of which projects above the draft-pole O, and is perforated with a series of holes, 3, in any one of which the hook of a double-tree is applied. The lower arm of the lever Pis connected bya cord or chain, c, to the bar Gr. By this arrangement the draft is made subservient in keeping the fin ger-bar M slightly elevated, so that it will run freely and lightly over the surface of the ground, and the force of the pull on said lever-P may be varied, so far as the force thereof is conveyed to the bar G, by connecting the double-tree higher or lower to the arm of the same extending above the draft-pole 0. To the outer end of the fingerbar M a shoe, q, is attached, which may be of the usual or any proper form, and which is provided, at its back end, with a series of teeth, a, with which similar teethn. on the under side of a plate, R, engage, said plate being on the upper surface of the finger-bar, and both the plate and the shoe being secured to it by a screw, 0. er, S, is attached, of the usual form, and it will be seen that by loosening the screw 0 the plate To the plate It a track-clear- B may be turned to give the track-clearer more or less of an oblique position, and that the teeth a a will, when the screw 0 is set up, hold the said plate and track-clearer firmlyin place. This track-clearer is adjustable according to the state or condition of the crop of grass, so that, whether the latter be heavy or light, a free track will always be obtained for the inside shoe of the machine to pass along in the subsequent swath.

Having described my invention, what I claim as new is 1. The combination of the lifting-lever with the pulley, having a sliding axis, and the finger-bar, substantially as set forth.

2. Brace H, with its rear end attached to, and moving in, the curved slot at the rear end of arm F J, in combination with said arm and with the supporting-pendant pivoted at one end to the frame, and at the other end to the brace, the front end of said brace being connected with the coupling-bar or bar G, as set forth.

3. The combination of coupling-bar G, connected to, and vibrating on, the gear-frame, and the flexible connection between said coup ling-bar and the whiffletree, as described.

4. The track-clearer S, applied to the outer end of the finger-bar, and made adjustable by means of teeth at the heel of the ear, to which the track-clearer is attached, adapted to mesh into corresponding teeth at the heel of the shoe, and a suitable clamp-pin device, as de-. scribed.

5. The combination, in a draft or gear frame ofa mowing-machine or harvester, of the sides E and F J, and tube D, through which the axle A passes, all constructed as described.

6. The combination of the gear and cutting apparatus supporting-frame, composed of one piece extending in front and rear of the axle;

and supported and keptin position by the axle passing through the tube, or through a hole or opening through said frame, and the gearing and shafting to operate the cutting appa-' ratus secured to, and supported by, said frame and axle between the two driving-wheels, and the cutting apparatus connected to said frame within or between the planes of said driving .wheels, substantially as and for the purpose set forth.

7. The frame of a mowingmachine or bar vester, composed of one piece, mounted upon, and supported by, the axle, as set forth, and

having one side or arm hollow or dished, by which the crank-shaft to operate the cutting apparatus is saddled, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses JAMES PINE.
