IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 18,562, dated November 3, 1 857; Reissue No. 1,778, dated September 27, 1864.

To all 'whom it may concern:

Be it known that HosEA WILLARD, of Vergennes, in the county of Addison and State of Vermont, and ROBERT Ross, formerly of same place, but now residing atSt. Albans, in the county of Franklin, in said State, invented certain new and useful Improvements in Grain and Grass Harvesting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which-` Figure 1 is aplan or top View, showing one mode of applying said improvements when the machine is to be used asa reaper. Fig. 2 represents a front view of Fig. l with the leading-wheel removed to show the parts ,in rear ot' it more fully, the conpling-arin, finger-beam, and platform being shown in different positions to illustrate the flexible connection of the linger-beam with the machine. Fig. 3 represents a section and sideA view on line x, Fig. 2, when the parts are in the positon shown in black lines. Fig. 4 represents in black lines a. front view of the machine when arranged for mowing, and in blue and red lines two of the different positions which the finger-beam and cutting apparatus are made to assume. when being prepared or folded for transportation. Fig. 5 represents a section on lines y y, Figs. 1 and 4,-when the machine is arranged for mowing, as shown in black lines, Fig. 4. Fig. 6 represents a plan or top view of linger bar or beam F', shoe F, leading-wheel g", and part of the coupling-arm or finger-bar extensionpiece E; and Fig. 7 represents a side view of one of the fingers and an end or cross section of the finger bar or beam, showing how a part of the linger is made to rise up by the front edge of the bar to keep the cutter-bar from working forward.

The side ot' the machine which runs next to the standinggrain I- call the insidef and that which runs next to the cut grass or grain I call the outside f In the accompanying drawings the main frame, which is of rectangular form. is represented by the letters A A A' A'. To the under side of the parts A A are`fastened the bearings of the main shaft or journal of the driving and supporting wheels B B. To the inner hub of the latter is fastened a ratchet wheel or device, ct', while a similar ratchet de-` vice, a', is fastened to the outer hub or side of wheel B.

Wheels B B', with their hub-ratchets, are tited loosely Aon shaft X. A sliding ratchet wheel or device, b', works on shaft X, and is so coiiected therewith as to be revolved when said shaft revolves, but is susceptible ot" a lateral movement, so that it can be moved in and out of action with ratchet a by means of pin c' in lever O, whose front end is pivoted to the under side'of piece B, fastened tothe front of the frame. Pin c' ts into a groove turned in the part b', so that the part b operates like a sliding revolving clutch. A similar ratchet or clutch, b, is fitted to be worked by lever O' on the outside of wheel B.

O" is the drivers seat, which is fastened to the rear of the main frame, and in such a position as that levers C and O are both within his reach. As the machine is drawn forward b v tongue O (shown in section) wheels B B revolve, and when both or either of the clutches b b' are in action with theirY respective ratchcts a a shaft X is caused to revolve, together with cog-wheel D, fastened thereto, and whichgears into cog-wheel D on a shaft, X', supported at one en il by a hanger, D", depending from piece A", and at the other in a projection d from hanger D, in which the short crank-shaft turns, the latter having on its rear end a bevetgear, d, which is operated by -bevel-gear d on the end of shaft X'.

On the front end of the crank-shat't is fitted a balance wheel, e, with a crank pin, upon whichis placed the outer end of the pitman e', which gives inoton to the cutterbar e", to which are attached teethf, which work as they vibrate through slotted open- Iingersf.

The improvements which form the subject of this patent relate to that class of mowing-machines in vwhich provision is iliade to allow thel tingerbeam to have an up-aud-down motion to conform to the irregularities of the ground independent, or nearly so, of the up-and-down mot-ion ofthe main frame,- aiid consist, first,in combining with the heel of the finger-beam, or the shoe which supports it, a finger-bar extension-piece or coupling-arm,so constructed and connected with the main frameasthat the whole or only the outer end of the finger beam can rise up or fall down Without necessarily requiring the front of the frame to rise or fall at the saine time, in combination with giving to said tingerbar extension piece or coupling arm a friction-support at or near its inner endthat is, the 'end next to the tinger-bealn-thus dispensing wi'h the use of hinged braces; sec- 1 tension-piece or couplinga support to -prevent it from beitig hoisted back or forward when the machine is in operation or being backed third, in the arrangement of said finger bar extension-piece or coupling-arm in such a mati- Iier asrespects the main frame that-one of its ends will be connected to the front outer corlier of the main frame, while the other end projects out under or by the front inner corner' ot' the main frame, iii combination with giving n. friction-support to said iingerbar extensionpiece or coupling-arm to prevent-it from twisting back when the machine is in use.

In the accom panyingdrawin gs, F represen ts the inger'beani or bar, the heel end of which is connected firmly to a shoe, F, to which one end of the linger-bar extension-piece or coupling-arm E is connected-iti this instance by a hinge or joint-the other end of E' being connected tothe outer front corner of the main frame by m'eaus ot" a bracket, Eand jointj'".

To the inner front cornerof the main frame y a metallic loop, E", is attached, and through which the tingerbar extension-piece or coupling-arm E' passes, after which it is connected to shoe F by a joiiit,as seen at g g. As the machine is drawn forward it carries forward the extension or coupling piece E', and that iii its turn carries forward the finger beam, to which are attached the lingers j", through which cuttersfon the cutter-bar c work. As the machine advances the linger-beam is free to rise and fall bodily, or at the outer end, to

vconform to the inequalities of the ground, by

reaspn of the yielding naturefof its connection with the main frame.

To give the linger-bar extensioii-piecc oi" coupling-arm proper support and'prevent it troni being twisted back when the machine is cutting or in operation, also to prevent it from being twisted forward when the machine is backed, and yet dispense with the use of hinged braces, a friction-support is employed. Itis formed by loop E, which passes on each side ofthe extension-piece or coupling-arm, so

to which itis connected at all times in its proper and relative position at the side ofthe machine, and that, too,without preventing its rising-and-ialling motion, to ena ble the cutters to sever the stalks of grass close down to the ground when the machine is in operation, even on rough or uneven ground.

For a more full `description of the various parts of the machine shown in the drawings reference can be had to other patented divisions of even date herewith, only so much of the machine having been described in this specilication as was deemed necessary to illustrateone mode of applying the improvements which forni the subject-matter ot' this patent to practical use.

What-is claimed, therefore, as the invention vof said WILLARn and Ross under this patent isi 1. The combination, with the heel of the iinger-beam or the shoe which supports it, of a yielding finger-bar, hinged extension-piece or coupling-arm, and a friction-support, substatitially as and for the purposes herein described.

2. The combination otl a metallic loop with the shoe which supports the heel of the finger bar or beam and the linger-bar extensionpiece or coupling, whereby the use of a hinged brace is obviat'ed, while the heel ot' the linger bar or beam is allowed to yield up and down to conform to the inequalities of the ground, and at the same time, is kept from beingtwisted back when the machine is in operation or forward when the machine is backed, substan' tially as and for the purposes herein described.

3. The arrangement ot' s-iid finger-bar extension-piece or yielding connection iii such a manner as respects the main trame that one of its ends will be connected to the front outer corner of the main frame, while the other end projects out by the inner front corner of the main frame, there to connect with the shoe which supports the heel of the finger bar or beam, in combination with a friction-support, for the purposes as stattd, substantially as and for the .purposes described.

In testimony whereof l have hereunto sub-I scribed my name. n
