HOBAR'Ir H. SMITH, OF CARLISLE, PENNSYLVANIA, ASSIGNEE BY MSNE ASSIG-N MEN T 0F C. M. IIUFKIN.

niv. o. Letters Patent No. 153,173, dated September 8, 1857 reissue No. 2,401, dated November 2.7, 1855.-

Beit known that C. M. LUFKIN, of Acworth, in the county of Sullivan, and State of New Hampshire, -nted certain new and useful improvements in Harvesting Machines; and I do hereby declare the following to be a full, clear1 and exact description of the part thereof` embraced-in this application, reference ,being lhad to the accompanyingdrawing, making part of the same, in which- Fig-ure 1 is a transverse section of a harvesting machine, embracing said improvements, taken in line '.1:v as, iig. 2.

Figure 2 is a plan or top view of the same.

Figure 3 is a transverse section in line y y, lig. 2, showing the means for raising and lowering the cutting apparatus; and

Figure 4 is a detached view showing a means for adjusting the angle of the cutters.

Similar letters of reference indicate corresponding parts in the several figures.

The improvement embraced in this application consists in com billing, in a two-wheeled, side-draught machine, a main frame, arranged between the wheels, a vibrating draw-bar, or its equivalent, and a laterally-projecting hinged cutting apparatus, in such manner that said cutting apparatus shall be free at each end, independently of the other end, and of `the vertical movements of the main axle of the machine, to follow the surface of the ground for the purpose hereinafter specified. It also consists in combining a laterallyT projecting hinged cutting apparatus, which is free at each end, independently of the other end, and of the vertical movements or vibta- ,tions of the main axle, to conform to the surface of the ground over which it is drawn, with one end of a vibrating draw-bar, or its equivalent, which is connected at its other end to the main axle gear centre, or its, equivalent, in such manner that the vibration of said draw-bar shall not interfere with the proper working ot' the mechanism through which motion is imparted to the cutters.

To enable others to construct and use said improvement, I will describe, with reference to the drawing,.- how the same may be carried out in practice. I

In said drawings, A represents a main frame arranged between the niain carrying-wheels C CQ and conneet-ed at one end to the main axle B, on which thc wheels C C' are mounted; said frame being shown as made in a triangular or bracing form, and provided with perforated lugs or ears, by which it is connected to the axle, on which it is free to vibrate :1s a centre. -The wheel C is keyed to the axle B, turning therewith, and is the drive-wheel from which motion is communicated through suitable gearing on' the frame to the cutters. I) is thc finger-bar of the cutting apparatus, arranged to project on one side only of frame A, to the vibrating end of which it is connected by a hinge consisting of hook, a, passing loosely through an eye formed in the extended inner or heel end of bar D, in such manner to turn freely therein. E is the draw-bar, which is connected at one end to the inner end ofthe axle or shaft, B, of the drive-wheel C', outside of wheel C, the connection of the bar with the axle being such as to allow said axle or drive-wheel shaft to turn freely, whilev the other end of the bar is left free to vibrate thereon asa centre, to allow the iiuger-bar D, which is connected to said draw bar, to rest upon the ground and freely follow the undulations in th(` surface thereof as it is drawn forward.V The tinger-bar is connectcdto the vibrating ond of the draw-bar by means of a hinge joint, which consists in this instance of a hook, b, which is attached to the vibrating ond of the draw-bar, und which passes through an eye formed in the iingcr-bar, near its inner linger or shoe, in such manner as to allow the linger-bar to turn or vibrate thereon, to follow the surface of the ground at each ond indopenfjh-ntly of the other. lho bar Dis shown :is extended inward beyond vthe brace or (,lraw-lmr F, to ailbrd a means oilattnelnnent at a to the vibrating end of the frame, similar to that at 6, above described, with the vibrating bar E. By thc construction' herein described, whereby the bar E is allowed to vibrate about the axle or gear-centre B, independently of the fra-nie. and whereby also the iinger-bar is adapted to turn on said bar, E, as a centre, the cutting apparatus is not only allowed to follow bodily the nndulatons in the surface of the ground, but enc-h end is rendered independent of the other end, and of the vertical movements or vibrations of the main axle, which, it' the bar E were made a part of and rigidly connected 'to the frame A, it is obvious would not he possible, und if the bar were connected to and allowed to vibrate from any other point than a gear or driving-contre of :he machine it would neces sarily causo a displatwincnt or strainingol' the parts through which motion is communicated to the cutters.

By the arrangement and construction illustrated in the foregoing` description, all danger of twisting or straining the driving mechanism is avoided; the cutting' apparatus projecting laterally from the frame by which it is drawn forward, is properly supported and sustained in its Working position at right angles to the path 'of the machine, while at the same time it is free at each end, independently of the other end and of the vertical movements or vibrations of the main axle, to followY the nndulations in the surface of the ground over which it is drawn.

Other partsof the machine shown by the drawing, being fully described in other applications of even date herewith, do not require further description here.

Whats claimed under .this patent, as the invention of C. M. LUFKIN, is

1. In a twoswheeled, side-draught machine, I claim the combination of a main frame, arranged between the wheels, and a vibrating draw-bar, or its equivalent, with a laterally projecting hinged cutting apparatus, which is free at each end, independently of the other end and of the vertical movements of the main axle, to conform to the surface of the ground overwliich it is drawn. i

2. The employment, in atWo-wheeled, side-draught machine, of a draw-bar, o1' its equivalent, connected at one endto, and vibrating about, a shaft or gear-centre of said machine, in combination with a main frame arranged between the wheels, and a laterally projecting hinged cutting apparatus. l

3. A draw-bar, or its equivalent, connected at one end to, and vibrating about, the main axle or gearcentre, in combination with a laterally projecting cutting apparatus, hinged to the other end of said bar.

In testimony whereof I have hereunto set my hand this 22d day of October, 1866. Y HOBART H. SMITH.
