i IMPROVEMENT IN MOWERS..

Specification forming part of Letters Patent No. 200,289. dated February 12, 18785 application filed v April 1, 1876.

To all whom it may concer-1i:

A Be it known that I, J AMES HARRIS, of J anesville,in the county of Rock and State of Wisconsin, have invented new and useful Improvements in Harvesters; and I do hereby declare that the following isa full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The invention consists, mainly, first, in the combination, with a turning drag-bar, of a sectional lever, having a detachable or folding portion 5 and, second, in the combination, with the knife-bar, of a sliding gravity-hook, for retaining .the knife-bar in place when the bar is folded.

It further consists in certain other combinations and certain details of construction, which, in connection with the foregoing, will be fully described hereinafter.

In the drawings, Figure 1 represents a side elevation of my Aimproved harvester with the cutter-bar in section 5 Fig. 2, a plan view with the cutter-bar folded; vation of the same5 Fig. 4, view, in elevation, of thetongue-iron and its connections 5 Figs. 5, 6, and7, views of the-pitman-joint 5 Fig.y 8, the yfolding ylever 5 Figs. 9, 10, and ll, views of the sliding hook for holding the cutter-bar5vFigs. 12, 13, 14, 15, and 16, views of the clutch mechanism;

.To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its construction and manner of operation.

For convenience and clearness of description, the separate mechanisms .'will be described under different heads, as follows: First, the drag-bar and the devices which make it cap-able of turnin g when the cutter-bar is folded;

second, `the folding lever and its combination with the turning drag-bar; third, the knifebar, and the sliding hook which holds it in place when the cutter-bar is folded-5 fourth,

the variable shoe or runner; iifth, the pitmanjoint 5 sixth, other details of construction.

First. The drag-bar and the devices which Fig. 3, a vrear-end eleceive and hold the eyebolta, Fig. 1, having a bearing-shoulder, al, washer a2, and a fastening-pin, a?, as shown.

B represents a bar or plate, forming the drag-bar proper, which is loosely held at its front end by the eyebolt ain such manner as to permit its rear end to have free vertical `movement, and is provided at its rear end with standards or ears b, having bearings, as shown. B represents a bar or shoe, Which is provided at its front end with .a horizontal socket and with the projecting arm or standard bl, and at its rear end with a suitable recess for holding the inner end of the cutterbar. b2 represents a pivot-pin, by means of which the shoe and drag-bar are united.

C represents a lever, and C a rack, adapted to hold the lever in any desired position, the special construction of both of which will be hereinafter described. c represents a connecting-bar, by means of which the lower end of the lever is united .to the upper end of the standard or arm b1, as shown.

I), Fig..1 and Fig. 1b,represents a casting,

suitably secured to the shoe at any proper point, which is providedwith the ear or standard d, having a convex projection, d', as

shown.

E, Figs. 2 and 2f, represents a casting suitably secured ,to the main frame at any proper point, which is provided with .a similar convex projection, c., as shown.

F represents a brace-bar, constructed of proper length and suitable material, which is provided at its ends with concave recesses adapted to bear upon the convex projections of the castings, before described. The opposite faces of the bar are also made convex, as shown.

f represents through proper brace-bar and the castings, against which they bear, which is provided with any suitable shank, but with a head having a concave face .a bolt, adapted to project openings in the endsof the -f upon its inner side, adapted to bear against the corresponding surface of the brace-bar, as shown. This bolt is secured by nuts in any proper manner.

The operation of these parts is substantially as follows The drag-bar, by means of its construction, is adapted to have a double movement-that is, it may be adjusted at its rear end in a vertical direction, for the purpose of tilting-the shoe to roll the cutter-bar, or it may be turned on a horizontal axis, to permit the rigidly-attached cutter-bar to -be folded.

The operation of tilting or rolling the cutter-bar has been described in an application coincident with this, and it will not be referred to in detail here.

The operation of turning will be readily understood. When the cutter-bar is folded, the shoe and drag-bar turn freely with it, this movement being permitted at one end by the eyebolt a, which turns freely in its socket, and at the other by the pivot-bolt of the brace-bar and casting. By means of the construction described it is possible to locate the actuatinglever at one end, out of the way of the drivewheel. It is possible, also, by means of this special construction, to cause the central parts, by proper adjustment of the lever, to lie close together, so as to occupy little space in turn- Second. The folding-lever and its combination with the turning drag-bar: C, Figs. l, 2, and 8, represents a lever attached to the turning drag-bar, near its front end, which is adapted, as before stated, to adjust the rear end of the drag-bar for the purpose of rolling the cutter bar. c1 represents its shank or main portion, suitably pivoted at the proper point to the rack-casting C', and attached at its lower end to the adjustable connecting-rod o, as shown.

o2 represents an opening for holding the spring-bolt c3, which is adapted, when free to act,l to press the projection c4 of the lever into the proper recess of the rack-casting, and securely hold it against accidental displacement.

c5 represents a bend in the upper part of the lever, by means of which its upper portion, attached thereto, is inclined into a convenient position for operation by the driver. c6 represents a socket, and 0"' an inclined face, forming the termination of the shank or main portion. c represents the handle or upper portion of the lever, consisting of a suitablyshaped bar, provided at its lower end with ears, by means of which and a suitable pivotpinit is hinged to the socket of the shank. e9 represents a spring -bolt, provided at its lower end with a double-inclined face, adapted to engagey with the corresponding face c7 of the shank when the handle of the lever is brought to its proper position, and also to release itself automatically when force is eX- erted upon the lever to fold it.

C represents the rack, consisting of a casting of any proper form, rigidly secured to the drag-bar, which is provided with a proper slot `for guiding and holding the spring-bolt c3, and also with a series of teeth adapted `to hold the lever in any desired position in the usual well-known manner. This casting, it will be observed, is strongly secured to the drag-bar, and is so located as to most advantageously take the strain incidental to the contact of the hinged portion of the lever with the frame when the cutter-bar is folded.

The operation of these parts is substantially as follows: The lever is adjusted in either direction for rolling the cutter-bar up or down, and is held in any desired position by means of the rack-casting and the spring-bolt. When the cutter-bar is folded and the drag-bar consequently turned, the lever is caused to fold itself automatically, as shown in Fig. 2, by

the contact of its hinged end with the frame,

or some relatively-fixed portion of the harvester, the spring-bolt dsengaging itself from the termination of the shank withoutl attention of any kind. When the cutter-bar is unfolded again the lever may be restored to its normal condition by simplyturning the hinged part back to its place, when the spring-bolt will unite the two parts together.

Third. The knife-bar and the sliding hook which holds it in place: G, Figs. 9 and 10, represents the knife-bar, of the usual wellknown or other proper construction, which is held by the finger-bar g and-the operatingpitman, in the usual manner. gl represents a casting secured -to the finger -bar, near its inner end, which is provided upon its bearingface with a recess, g2, located at an angle tol the line of the movement of the knife-bar, as shown. g3 represents a shoulder projecting into the recess, which is adapted to limit the downward movement of the sliding hook. g4 represents the sliding hook, consisting of a plate or bar adapted to move in a longitudinal direction in the recess, and provided at one end'` with the hook proper g5, and at the other with the projection g, adapted to strike against the limitingshoulder of the recess at the proper time and check further movement. g" represents a stud or pin projecting at right angles from the face of the hook, by means of which it may be moved by the hand, if desired.

The operation of these parts is as follows: When the folding of the fin ger-bar takes pl ace., the knife-bar, unless specially held, is free to slip down and cause trouble. With the construction described, however, this difficulty is avoided. The sliding hook, moving down its inclined recess in advance of the knife-bar,.and projecting into the line of the movement of the latter, consequently furnishes a stop, which arrests its movement and holds it securely in place.

Fourth. The variable runner: H,Figs. l, 2, and 3, represents a runner, consisting of a suitable metal plate, which, at its front end, is so bent as to hook over the socket of the joint, and also, at its rear end, is bent -in such manner as to form aright-angled termination, as shown, the vertical part being provided with a series of openings, by means of which `it-may be secured to the casting at different heights. By means ofthe construction described, the front end of the shoe protects the same from being caught in its.,

movement over the ground. L v

Fifth. The pitman-joint: I, Figs. 5, 6, and 7, represents the pitman, which receives its proper reciprocating movement in any suitable manner from any proper source. 'i represent spring-bars, which form that end of the lpitman which is attached tothe knife-bar,

one of which is provided upon its inner face witha convex projection, z", and the-otheru-pon its adjacent face with a concave recess,-z,

as shown. 3 represents a disk, rigidly atitached to the knife-bar in any proper manner,

which is made semi-spherical inform, so` as to be adapted to rest -between the corresponding faces of the spring-arms, as shown.l t4 represents a securing-bolt, which' is adapted, by means of its nut, to draw the spring-arms closely together, and clamp the` intermediate disk of the knife-bar. l. 5 represents anut-lock,

held in place by theouter nut i6, by means of which the inner nut is prevented from turning..

Sixth: The rod for holding` the cutter-bar when folded: J, Figs. 2, 3, and`13, represents a rod adapted to properlyhold the cutter-barwhen in its folded position, which is loosely pivoted at one end to the brace-bar, and held at the other by means of a removable eyebolt, as shown. When it is desired to use the same, the bolt is removed from its place in the brace-bar by un-- screwing its nut, and then the rod is attached to the cutter-bar by inserting its shank in the proper opening j, as shown, and replacing the nut, this being done without detachin'g the bolt from the rod. By this means the bar is properly held when folded, and at other times the rod is conveniently carried on the bracebar without danger of being lost.

It will be observed, also, that when the cutter-bar is folded, as shown in Fig. 3, it will be so united to the bracebar by the rod J that the three parts may move together independently of the frame, so that if the lifting-lever becomes detached from any cause, these parts' may fall to the ground without injury to the rod, which, if secured to the frame, would probably be bent or broken.

K, Figs. 1, 2, and 4, represents the pole of the machine, pivoted in any proper manner to the front end of the frame. This pole is, preferably, attached, however, by means of an intermediate casting, 7c, provided with a suitable bearing-surface for. the rear end of the pole, and ears, by means of whichit is hinged to the frame, as shown. It represents an iron bolted to the rear end of the pole, which, extending in a rearward direction, is provided, at or near its -rear end, with a stud, k2, as shown.V

- L represents a casting, secured to the frame in any proper manner, ,which serves to support the vdrivers seat, as shown, and is provided with a pendent arm or ear, l, Fig. 4, having an opening adapted to hohl the stud of the arm, as shown. A'

l1, Figs. 1 and 2,.represents acatch, adapted to hold the end of the raising-lever Z2, as shown. By means of this construction the arm is so securedas to lock, upon the inside of the front beam ofthe frame, the pole, which is pivoted upon the outside.

M, Figs. 2 and 17, represents the frame of theharvester, consisting of a piece of angleiron, of suitable length, bent into the proper f quadran gular form, and secured at its adjacent ends by riveting or other proper means.

,N represents a journal-box, provided Wlth angular bearing-surfaces, as shown, which are adapted to cover the joint in the frame, and unite, either alone or in connection with other means, the adjacent ends together. n also represents a journal-box, located at the opposite end of the frame, and attached thereto in any proper manner.

O represents a shaft, adapted to operate the pitman of the cutter-bar, which is held by the journal-boxes `N n, and consequently lies inthe angle ofthe frame, as shown.

Some ofthe advantages. of the described vconstruction are as follows: .By making the frame of angle-iron,y great strength and rigidity are obtained with little material, and also convenientvertical and horizontal surfaces are furnished, to 'which the auxiliary parts may be readily attached.

By locating one of the journal-boxes at the joint, and providing it with angular bearingsurfaces, as described, the frame is greatly strengthened at its Weakest point. The location of the shaft, also, within the angle of the frame is advantageous, as the parts are compactly arranged, and space is economized.

P, Figs. 12, 13, 14, 15, and 16, represents a clutch-box, rigidly fixed to the main shaft or axle, which is provided on its inner periphery with the usual series of clutch-teeth p, adapted to en gage with the springpawl upon the main Wheel, in the usual well-known manner.

p represents an auxiliary series of clutchteeth, located/on the inner vertical face ofthe clutch-box, which teeth are arranged in a position the reverse of that of the clutch-teethp, and hence are adapted to give, when in operation, revolution to a pawl in a forward direction.

rEhis inner series of clutch-teeth is adapted, when the machine is used as a reaper, and the main wheel is consequently removed, to

give movement to a chain-wheel adapted toA ing answers the double purpose of a clutch, for

driving the main shaft of the mower, and also for driving the rake of the reaper when the drive-wheels are removed and placed together.

By means of the various details described the construction is simpliiied, and the efficiency of the harvester increased.

I do not limit myself to the precise construction shown and described. Various modifications may be made without departing from the spirit of my invention. For instance, if desired, the upper portion of the lever G may be detached, when the drag-baris folded, by

removing its pivot-pini; or it may be folded A combination with the recess having` a limitin l shoulder, as described.

parallel with the drag-bar, if desired, instead of at right angles to it 5 and when this is practiced the devices for making its action autothe runner H, the drag-bar B, the rear end of Awhich projects beyond the front end of the i shoe and protects the same, as described.

matic may be dispensed with.

Instead of using the spring-bolt, a simple spring may be used to accomplish the same purpose.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a turning drag-bar, a sectional lever, having a detachable or folding` portion, as described.

2. [n combination with the lever G and foldl 9th day of March, 1876.. and the connecting-rod c, pivoted to lower end l of lever C, and above the drag-bar to the arm t b, the construction being such that when the i lever is properly operated the arm bl and rear t end of bar c may be caused to approach the 1 drag-bar, to avoid contact with the wheel in g ing drag-bar B, the shoe B', having arm b1,
