SPECIFICATION forming part of Letters Patent No. 609,891, dated August 30, 1898.

Application filed January 22, 1897. Serial No. 620,170. (No model.)

To @ZZ whom it may concern:

Be it known that I, J AMEs MAOPHAIL, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Reaping-Machines,which is fully set forth in the following Aspecification, reference being had to the accompanying drawings, in which- Figure l is a plan view of a reaping-machine constructed according to myinvention. Fig. 2 is a side elevation thereof in the direction of the arrow of Fig. 1 with the drivingwheel omitted, showing the platform tilted up. Fig. 3 is a similar elevation showing the platform tilted down. Fig. 4 is a rear elevation of the machine. Figs. 5 and 6 are detail views of the attachment of the tilting-lever to the tilting-rod. Fig. 7 is a detail elevation of the seat-casting. Fig. Sis a plan View of the same.

My invention relates to reaping-machines, and particularly to mechanism therein adapted to tilt the platform and raise or lower the sickle-bar and to the seat-mounting and connections.

In the drawings I have omitted certain parts of the complete machine which have no connection withmy-improvement, and many of the parts shown are of ordinary construction and will be but brieiiy described.

Referring to the drawings by letter, A represents the platform, A the sickle-bar, B the.

grain-wheel, and C the gear-frame, of areapin g-machine. The driving-wheel D is mounted upon an axle D', forming part of the wheel-frame E. To the said wheel-frame is secured a yoke E', in which is mounted the roller E2. The gear-frame C is swung from the roller E2 by the U-bolts e passing over the same. The roller AE2 is disposed nearly in line with the axle of the grain-wheel B, and the forward edge of the platform is thus free to tilt up and down from the axis so formed.

Upon the axle D', outside of the drivingwheel, I mount a casting F, comprising a sleeve F', adapted to surround and be secured to the said axle by the pin f, a forwardly-prolading Mm F2, and a Short rearwardly-extending bracket F3. In the end of the arm .the foot-lever f4.

F2 is formed a slotf, adapted to receive a stud or pivot f2, upon which is pivotally mounted The said lever has appropriate connections with the rake disposed in the usual manner and only part of which are shown in Fig. l. The seat F5 is mounted upon the post F6, to the lower end of which is securedthe footboard F7. The post F6 is rigidly secured to a short horizontal bar F2, the inner end of which fits within a box f3, formed in the bracket F3 of the casting F. The bar FS is secured in the said box by the pin f4, which in turn is held by the cotterpin f5.

Hitherto in this class of machines the seat and its connections have been so secured to the axle and the foot-lever so mounted upon the footboard, such as F7, that it has been impracticable to remove the seat when desired to drive the machine through a narrow gate. This has proved a great practical inconvenience, but is entirely obviated by the above construction, with which the seat may be readily removed by withdrawing the cotter-pin f5 and pin f4 and as quickly replaced again. The foot-lever being mounted upon the casting F in no wise interferes with this removal.

To the gear-frame C the rear end of a tongue or pole G is pivoted, as at g. A diagonal brace-rod G is also preferably employed pivoted at g to4 the pole and at g2 to the platform.

Referring more specifically to the tilting mechanism, I-I is a casting comprising a short arm H', pivotally mounted, as at h, upon the axle D, a socket H2, and a rack-segment H3. The suspending-bar H4L is pivoted, as at 7L', to a bracket H5, mounted upon and forming a part of the gear-frame C. The other end of the suspending-rod is adjustably secured, through one of the perforations h2, to the lower end of the rack-segment H2. The rear end of the carrying-bar I is rigidly'mounted in the socket H2, above described. Its forward end is bent, as at I', and is adapted to slide in a guide-box I2, mounted upon one side of the pole G.

A tilting lever .I is pivotally mounted upon the carrying-bar I, as at j. At its rearward end it is provided with a handle J', the dog IOO . slides forward in the guide-box I2.

j, and hand-latch jz, whereby the lever can be moved along and secured upon the racksegment H3. The forward end of the leverJ in front of its point of pivotal connection with the carrying-bar is provided with a short upwardly-extending arm J 2, to the upper end of which is secured one end of a coiled contraction-spring J 3. The other end of the said spring is secured by an eyebolt and nut to a bracket J4, mounted upon the carrying-bar. Any other means equivalent to the bolt and nut js, permitting the adjustment of the tension of the spring, maybe employed.

To the tilting lever J, between its pivotal mounting upon the carrying-bar and the handle J is rigidly secured a small bracket K, in the lower part of which there is formed the bearing for a swivel-pin K. The said pin-is provided with a head K2, in which is formed a screw-threaded aperture adapted to receive a screw-threaded rod K3. The upper end of the rod K3 is provided with a crankhandle K4. The lower end is rotatably mounted upon the platform, as at K5.

The ope-ration of these parts will be readily understood in connection with the drawings. In Fig. 2 the machine is shown in its normal position, with the sickle-bar raised. When it is desired to lower the sickle-bar, the tilting lever J is moved down the rack-segment H3. The rod Kis thus depressed in respect of the carrying-bar I,the forward end of which The front edge of the platform and the sickle-bar are thus lowered to any desired extent Within the range of adjustment of the rack-segment.

y When it is desired to raise the sickle-bar, the

tilting lever J is moved upward along the l rack-segment and the front end of the platform. is raised by the rod K3. During this operation the spring J 3 materially assists the operator, aiding him in overcoming what otherwise is a very considerable weight, and the said sprlng may be so adjusted in tension rals to permit of the tilting o f the machine with but a minimum of exertion. By means of the adjustable suspension-bar H4 and the screw-threaded rod K3 it will be seen that the range of tilting of the platform can be adjusted either higher or lower.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isj A l. In areaping-machine, the gear-frame C pivotally mounted in relation to the drivingwheel, the pole Gr pivotally attached to the gear frame, the carrying bar I pivotally mounted in relation to the driving-wheel and having its forward end slidingly mounted on the pole G and the rear end formed in a segmental rack and adjustably connected to the gear-frame C, the substantially L-shaped lever J pivotally mounted on'the bar I and having the spring-latch cooperating with the segmental rack, the screw-threaded rod K3 having bearings in the frame O and in the pivotal nut K2 carried by the bar I, and the spring J3 connected to the bar I and to the upturned end of the lever J, substantially as and for the purposes described.

2. In a reaping-machine, the axle D'; the casting F mounted upon the axle; the footlever F4 mounted upon thecasting; and the seat F5 and its connections detachably mounted in the said casting. v

3. In a reaping-machine, the axle D', the casting F, comprising the forwardly-extending arm F2 and the bracket F3, provided with a box f3; the foot-lever F4 mounted in the said arm F2; the seat F5; the seat-post F6; and the horizontal bar F8 secured at one end to the seat-post and detachably secured at its opposite end in the box f3, substantially as described.
