WILLIAM BAYLEY, OF SPRINGFIELD, OHIO, ASSIGNOR TO THE TORONTO A REAPER AND MOWER COMPANY, OF SAME PLACE.

MOWI NG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 392,658, dated November 13, 1888.

Application filed J nnuary 3, 1887. Serial No. 223,179. (No model.)

ToaZZ whom it may concern:

Be it known that I, WILLIAM BAYLEY, of Springfield, in the county of Clark and State of Ohio, have invented a new and Improved Mowing-Machine, of which the following is such a full, clear, and exact description as will enable any person skilled in the art to which it applies to construct and use the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to mowing-machines in general and particularly to that class of machines commonly known as two-wheeled chain-drive-gear machines, and is in the nature of improvements upon the usual form, arrangement, and construction of such machines.

The objects of my invention are to so con struct a mowing-machine that by peculiarlyjointed connections the cutting apparatus may be raised to a vertical position, the inner end thereof rise and fall, the outer end rise and fall, the points of the fingers or guards tilt up or down to follow the undulations of the ground over which it passes, all these operations being accomplished while the machine is running. These objects are successfully accomplished by means of the devices hereinafter described, and illustrated in the drawings hereunto attached.

In the drawings, Figure 1 is a side elevation of the complete machine. Fig. 2 is a plan of the machine, omitting the elevating and tilting levers. Fig. 3 is a vertical section through the main shaft, main frame, and master-wheels, showing the device for throwing the machine into and out of gear. Fig. 4 is a side elevation, and Fig. 5 is an end elevation, of the shipping-lever by which the machineis thrown into and out of gear. Fig. 6 is a partial side elevation showing the device for tilting the cutting apparatus. Fig. 7 is a partial side elevation showing the device for raising and lowering the inner end of the cutting apparatus. Fig. 8 is a partial side elevation showing the device for elevating and depressing the outer end of the cutting apparatus. Fig. 9 is a cross-section through the drafttongue and sliding whiffletree-bracket. Fig. 10 is a perspective view of the inner shoe and the bracket to which it is pivoted. Fig. 11

. shaft, gear-case, &c., on a line with the crankshaft. Fig. 14 is a perspective view of the supportingbar. Fig. 15 is a perspective view of the drag-bar; and Fig. 16 is a side elevation of the sprocket-wheel, sprocket-pinion, and chain-tightening device.

Similar letters refer to like parts in the several views.

A is the main frame, consisting of a long pipe box or tube of cast metal, through which the main shaft b passes loosely. At the rear side of the frame A and near its center is formed the seat-spring bracket a, to which is attached the seat-spring a, supporting the drivers seat A". At the front side of the main frame and near one end is formed the lug or car a to which is pivoted the supportingbar 0, and another lug, a, to which is pivoted the diagonal brace D, While the draft-tongue T is fixed to the bracket a also formed on the front side of the main frame A. Upon the outer ends of the main shaft 1) are pivoted or journaled the main driving and supporting wheels 13 and 13*, which are provided with the backing-ratchets N, which, during the forward movement of the machine,are'eng aged by the usual pawls, b pivoted in the plates b and b fixed to the main shaft in the usual manner.

Loosely fitted upon the main shaft is the sprocket-wheel E, upon one end of whose hub is formed the half-clutch e, which engages the half-clutch c on the backing ratchet-plate b, as hereinafter described. A portion of the hub of the sprocket-wheel E is recessed in the form of a sleeve and fits over a portion of the pipe-box of the main frame A, which has a groove formed in it, the sprocket-wheel E being held in place by the pin 6 in the sprocket-wheel E, which enters said groove,

as shown in Fig. 3.

Upon the backing ratchet-plate b is formed a sleeve over which is fitted the shipper-lever F, a collar, b, formed on the plate If, engaging an inwardly-projecting rim, f, formed on the lever F, preventing lateral motion of the latter in relation to the plate I). Formed in the lever F is the cam-slotf", which is engaged by the hook f, which is fixed to the main frame by passing through a lug, a, formed thereon. The relative position, therefore, of the main frame to the plate I) is controlled by the shipper-lever F, and as the sprocketwheel E is carried by the main frameindependent of the main shaft or the backingplate I) and its haltcluteh c, it follows that by swinging the shipper-lever F back or forward the main frame and sprocket-wheel E will be moved laterally to the position shown by dotted lines in Fig. 3 and the machine thrown into and out of gear'17. 0., started and stopped-as may be desired, the spring pin f" in the shipper F engaging slight slots (not shown) in the main frame to hold the shipper in either position.

The lateral movement of the sprocket-wheel E in the act of being thrown into and out of gear is not sufficient to disturb the working relation of the drive-chain.

G is a casting forming a casing for the combined bevel-gear and sprocket-pinion J and bevel-pinion K, as well as a bracket to which the inner shoe, H, of the cutting apparatus is pivoted, and has formed upon it the projection y, to which is fixed the dragbar L, and also properjournals for the crank-shaft M.

The diagonal brace D is pivoted to the main frame at a*, and projects diagonally downward and forward to the gear-casing G, where it is bent at such an angle as to make it parallel to the main shaft 1). At this point it is circular, and, passing through the supporting-bar O at c, Fig. 11, and the drag-bar L at Z, Fig. 15, it forms a pivot orjournal, upon which the bevelgear and sprocket-pinion J revolves, after which it passes through the gear-easing G, and is perforated for the passage of the crank-shaft M, and confined to its place by a nut placed outside of the gear-easing G. The form, position, and relation of these parts are shown in detail in Figs. 11, 12, and 13, and in general in Figs. 1 and 2.

The supporting-bar C is pivoted to the main frame at a and projects forward and downward at right angles to the main shaft b, and is pivoted at c to the diagonal brace D, as described, the pivots at a and a serving to pivotally connect the cutting apparatus and its appendages to the main frame, by which the former may be free to rise and fall with respect to the latter.

It is obvious that the diagonal brace D and the supporting-bar 6 should, strictly speaking, be pivoted upon or around the main shaft 1) or the pipe-box of the main frame A, in order that the sprocket-pinion J may always maintain its proper position in relation to the large sprocket-wheel E on the main shaft; but by pivoting the diagonal brace D and supporting-bar O to the cars a" and c, which centers or pivots are directly in line with the main shaft 0 and sprocket-pinion J and quite near the main shaft, their positions are changed so slightly when the cutting apparatus is elevated and depressed that practically their working relations are not impaired.

The drag-bar L is fixed to the gear-casing G by bolts at g g and being braced by the brace-rod g and at its front end pivoted to the tilting-lever N,which in turn is pivoted to the whiffietree frame or plate Q, to which the whiffletrees are pivoted at d, which slides upon the track 1*,fixed to the draft-tongue, as shown in Figs. 1 and 2. By this device the cutting apparatus is tiltedi. 0., the points of the fingers elevated or depressed (turning on the diagonal brace where it passes through the bevel-gear as a center) by means of the tiltinglever N, which is held in any desired position by the latch a engaging properly-formed depressions or notches in the segment-plate q, forming part of the whiflletree-plate Q. This operation and the relation of the parts in the several positions are clearly shown in Fig. 6.

To the draft-tongue T is pivoted the foot lever 0, having a properly-formed foot-piece at the top and the bottom end extended beyond its pivotal point and being connected to the supporting-bar O by the link q. By this device the operator may with his foot press upon the top end ofthefoot-lever O and elevate the inner end of the cutting apparatus, as shown in Fig. 7, the whiflletree-frarne Q sliding upon the track P as necessary, and the catch-lever (f, pivoted to the drafttongue,serving to hold the foot-lever 0 whenever desired, the spring q throwing the catch-lever q" forward, so as to engage the foot-lever 0 whenever it is depressed.

The inner shoe of the cutting apparatus is pivoted to the gear-case G by sleeve 9, formed upon the rear end thereof, and by a simple pivotedjoint at h, the saidjoints being in the line with the crank-shaft. By this construction the vertical swinging of the cutting apparatus on the joints 9 and h does not disturb the working relation of the crank-shaft M and flywheel m.

The outer end of the cutting apparatus is elevated by the elevating-lever B, which is pivoted to a stud formed upon the gear-casing G, and having the right-angled projection 1', which is pivotally connected with the inner shoe by the link-rod S, the elevating-lever B being held in place by the usual catch-pin, 1"", engaging proper projections formed upon the segment U, which is formed upon the geareasing G. The operation of elevating is shown in Fig. 8, wherein the elevated position of the cutting apparatus is shown by dotted lines.

The cutting apparatus is driven by a drivechain, c, passing over and around the sprocket-wheel E and sprocket-pinion J, attached to the bcvel-pinion J, which engages and drives the bevel-pinion K, fixed to the crank-shaft M, upon which is also fixed the ico usual crank-wheel, m, from whose wrist the pitman V is connected to the cutter-bar W, sliding upon the finger bar X, in the usual manner.

The drive-chain e is tightened by the idlepulley Y, pivoted upon the lever Y which is pivoted at its lower end upon the diagonal brace D, and is secured in any desired position by the bolt 3 passing through the slot in a curved projection on the lever Y and into the gear-casing G.

Having thus described the construction, arrangement, and operation of my machine, and pointed out its new and useful features, what I claim as new, and desire to secure by Letters Patent, is

1. In a cutting apparatus for a harvestingmachine, a crankshaft, and a driving-gear in engagement therewith located upon and above the inner shoe of said cutting apparatus, combined with a lateral coupling arm or brace pivoted to said shoe on an axis coincident with the center of said gear, whereby the points of the cutters and guards may be tilted on an axis coincident with the axis of the driving. gear, substantially as set forth.

2. In a harvesting-machine, the combination of a rigid drag-bar fixed at its rear end to the bracket to which the inner shoe is pivoted'and at its front end pivoted by a suitable movable connection to a whifiietree-bracket, sliding upon the draft-tongue or some fixed part thereof, a diagonal brace pivoted at its front end to the bracket to which the inner shoe is pivoted, and asupportingbar pivoted at its rear end to the main frame and at its front end to the bracket to which the inner shoe is pivoted, in combination with a cutting apparatus, substantially in the manner shown and described, and for the purposeof enabling the cutting apparatus to freely follow the undulations of the ground over which it passes, and by suitable connecting parts to be under complete control of the operator to raise the inner end of the cutting apparatus independent of the outer end, or the outer end independent of the inner end, and at the same time V to enable the cutting apparatus to be rocked or rolled in the line of its length.

3. In a harvesting-machine, a whiffietree bracket or plate adapted to slide upon the tongue or some fixed part thereof and having pivoted to it a whifiietree and a tilting-lever, to which in turn is pivoted the front end of the drag-bar, substantially in the manner shown and described, and for the purpose of forming a direct connection between the whiffietree and cutting apparatus, and at the same time to allow the latter to be tilted up or down, as may be desired.

4. In a harvesting-machine, the combination of a whiftletree-plate sliding on the drafttongue or some fixed part thereof, a drag-bar pivotally attached at its front end to said whiffietree-plate, the rear end of said drag-bar being fixed to the bracket to which the cutting apparatus is pivoted, and a diagonal brace and a supporting-bar, each of which is pivoted atits rear end to the main frame and at its front end to the bracket to which the cutting apparatus is pivoted, substantially as shown and described, and for the purpose of flexibly connecting the cutting apparatus with the main frame, yet with the proper degree of rigidity to withstand the usual strains to which it is subjected.
