To all ir/iomy 1' t may concern:

Be it known that PHILO SYLLA, of Elgin, i'n the county of Kane, and State of Illinois, and AUGUSTUS ADAMS, formerly of the same place, but now residing at Sandwich, in the county ot' De Kalb, in said State, invented certain new and useful Improvements in Machines for Harvesting Grain, Mowing Grass, Src., of which the following is a full, clear, and exact description, reference being had to'the annexed drawings, which make part of this specifica-tion, and in which- Figure lis a view in perspective of a niachine, showing one mode of 'applying said improvements, the finger-beam being raised from the ground to adapt the machine for reaping. Fig. 2 represents a plan ot' a portion of the under side of the machine to exhibit more fully the exihle connection of the finger-beam with the main frame. Fig. 3 represents a plan ot' the machine, the finger-beam resting on the ground to adapt the machine for mowing. Fig. trep resents a vertical transverse section of the machine at the line l l of Fig. 3. Fig. 5 represents a vertical longitudinal section of the same at'- the line 2 2 ot' Fig. 3; and Fig. G represents a plan of the cutting apparatus, the finger-beam, and the coupling-arm for connecting the hoger-beam to the main frame. Fig. T is a vertical section at the line 3 3 of Fig. 6, showing the provision for allowing play in the joint between the finger-beam Igand the yielding bar K.

rlhat side ot' the machine which runs next the standing grain we call the left side, and the other, at which the horses are placed, we call the right side.

rEhe accompanying drawings representa machine having a frame large enough to support, in addition to the cutting apparatus and machinery required for mowing, a removable platform placed behind the cutter, (such as is common in ordinary machines adapted to reaping and mowing,) an elevated table behind the platform to hind the grain upon, stands for a raker and hinders, a dumping-tray to carry the sheaves until a sutcient quantity for a shock has accumulated and then to dump them in a heap upon the ground, and a stand or place for the driver of the team by which the machine is drawn.

W'henever it may he expedient to use one or more of the several parts or branches of said improvements separate from the rest, such part or parts might be used in connection with frames and gearing more convenient than those herein described, which are proportioned and arranged with reference to the use ofthe whole of the parts y together, and it is obvious that several parts of the said improvements are ap. plicable to various other reaping or mowing machines in use. One mode ot' applying each of these improvements to practical use is shown in this machine. It is therefore unnecessary to specify the manner ot' applying the parts, respectively, to other machines, as the that purpose.

In machines for mowing it is important for the cutting apparatus to run, as nearly as possible, parallel with the surface of the ground, and as this surface is generally more or less undulating it is necessary that the finger-beam should rise and fall freely, to ascend and descend the sides of the undulations that cross the swath at right angles, and to sway freely up and down at both ends to accommodate itself to the sides of the und ulations thatcross the swath obliquely, and to the varying transverse inclinations of the surface of the swath. Such swaying and rising and falling ot' the fingerbeam is much more free, and the finger-beam follows the surface of the ground much more readily when its ends are equally free to rise and fall; but such freedom is much interfered with when the linger-beam projects beyond the ends of the cutter farther than is necessary for the purpose of protecting it, first, because the length of the beam is increased hy such projection, and the cutter thereby prevented from cutting as near the ground, wherever the latter is a curve of which the linger-beam is the cord, as it would do it' the ringer-beam were shorter; second, beca-use the projecting end of the finger-beam would often pass along a ridge and hold up one end of the cutter at a distance from the ground beneath it, when the finger-beam, hut for such projection, would ordinary skill ot' a constructer is sufficient for ons heights from the ground.

have passed along without reaching the ridge, and ot' course closer to the ground, carrying the cutter and cutting the stubble shorter; and, third. because the shorter a finger-beam is, which is free to rise and fall at both ends, other things being equal, the more closely it will conform and the nearer it will cut to the surface of uneven ground; and theinvention which is thesubjeetofthispatentconsistsin the combination of a short tinger-beam-t. e., one of only s'uiticient length to protect the cutting apparatus, and not extending beyond the end ot'the cutter across the gearingtratne, like the ordinarylong linger-beam, which is often made halt' as long again as the cutter-with ayielding couplingarm or the equiralentthereot' to connect the finger-beam with the main frame in such manner as to allow both ends and eitheikend of the beam to rise and fall to accommodate itself to the surface ofthe ground.

In the accompanying drawings, the main trame A A A2 A3 A* B B B2 B3 E E' E2 is supported upon two wheels, D and D', whose journals rest in bearings in blocks C C', made adjustable to set the frame at a variable distance from the ground.:l`his frame is heavier in front ot' than behind the axis ofthe wheels l) D' andthe preponderating weight is sustained by a truck in front, composed of two wheels, E3 E3, and an axle, F, and connected with the main frame bya draft-bar,F2,hinged at its rear end on a pivot, F", to the beam A' of the frame. For the purpose of allowing the front of the main frame to be raised, lowered, and held at dierent heights the draft-bar passes through a strap, F3, attached to the beams E and A', and a wedge placed between the top of the stra-p and the draft-bar holds the front of the frame at any'reqnired height within the range ot' adjustment allowed by the strap, and it may be lowered by withdrawing the wedge, and may be held down by placing the` wedge between the under side of the dral'thar and the bottom of the strap. Alike et"- iect may be produced by passinga pinthrongh the strap above or below the draft-bar in the holes made for the pin in the sides of thestrap. By these means the connection of the draftbar with'tbe frame may by turns be limber or rigid, and the front oi' the frame set at vari- When the wedge and pin are withdrawn the front ofthe main frame and the front end of the tongue respectively are free to play up and down within the limits ot' the strap independently ot' each other. The ends attained by the adjustment already described may likewise be attained, to a certain extent, by adjusting the pivot F4, on which the rear end of the draftbar F2 hinges, from one hole to another in a series formed for its reception in the side of the beam A'.

The tongue F', by which the horses draw the machine, is attached to and extends forward from the axle of the truck.v

The motion of the cutter in this machine is derived from one of the wheels which carry the main frame. Ou the side of the right wheel, D, a bevel-wheel, G, is secured, which takes into and drives a pinion, G', on a counter-shaft, G2, which also carries a spur-wheel, G3, that takes into and drives a pinion, G4, on the end of ashaft, whose opposite end carries a crank, H, which, through a connecting-rod, H',joint ed to the cutter-bar HZ, communicates a vibratory motion toacutterarranged to play through a series of guard-ingers, J2, projecting from the front side ofthe finger-beam l2. The bearing of that end of the shaft G2 which carries a pinion, G, is in an upright arm, H3, hinged at its lower end to the frame, so that by turning this arm toward or from the wheel D the pinion maybe thrown into or outof gear with the wheel,to put the cutter into or out of rnction. The pinion is held in either position at will by means ot' a notched detent, I, pivoted to the main frame.

The cutter H2 and guard-lingers J'2 are of the usual construction and supported by the finger-beam in the usual manner.

The right end of the finger-beam I2 is connected to the frame by means of astrong link or conplingarm, J, hinged at its left end to the right end ofthe finger-beam, and at its rightend toa cross-beam, E', of the main frame.

The progressive motion ot' the frame on its wheels carries forward the coupling-arm, and that in its turn carries forward the linger-beam and cutter, and as the coupling-arm is rigid laterally' only and its lel't end, to which the finger-beam is connected, free to rise and fall, the finger-beam necessarily rests on the surface ofthe ground. Therefore,in passing over undulating ground the Jdnger-beam will rise or fall at either or both ends and sway up and down within certain limits to conform to the surface of the ground.

The coupling-arm and finger-beam are supported by a yielding bar or bruce, K, extending from the junction of the lett end of the coupling-arm with the right end ofthe tingen beam, backward, and connected. by a hinge, K", to the cross-barBSot' the frame. The rear end oft-he barK is extended some distance behind its hinge K2 and is enlarged to counterbalance the weight of its front end and that of the coupling-arm and of the connecting-rod,\\l1ich gives motion to the cutters, so that the right end ofthe finger-beam may bear as lightly on the ground and be as free to rise and fall as the left end. Since, however, this machineis designed for reaping as well as mowing, and must therefore be capable of carrying a platform whenever it is required to be used as a reaper,and when so used must likewise be capable of carrying the nger-beam at a height of several inches above the ground, a second yielding bar, K', is provided to support the left end of the ngerbeam, to which it is attached at its forward end and is hinged to the side rail, A2, of the frame on a pivot, Kt. The finger-beam being thus connected with the driving-wheel and with the frame for supporting the gearing, so as to leave it free to rise and fall at both ends,and at either end,within certain limits, Without disturbing the level of the other, these movements are greatly faciliiated and the adaptability ot' the finger-beam to the varying inclinations of4 the surface of the ground greatly promoted, as the Vsaid inventors discovered, by making the linger-beam short, as represented in the drawings-@Zapf only sntoient length to'protect the cutting apparatus, and not longenough to extend beyond the cutter-bar across the gearing-frame, as is common when the linger-beam is rigidly connected to the frame.

As the platform upon which the grain coll leu-ts as it is cut, the table upon which it is hound into sheaves, and the tray for carrying the sheaves until aquantitysuitahle fora shock has acouinulated and then dumping them in a heap, form no partot' the subject-matter of the claim under this patent, a further description of them here is deemed unnecessary.

What is claimed in this patent as the invention of the said SYLLA and ADAMS is-` The short finger-beam, in combination with the yielding connection with the main frame orits equivalent, substantially as herein set forth.

In testimony whereof We have hereunto subscribed our names.
