IMPROVEMENT N HARVESTERS".

Speciii'cation forming part of Letters Patent No. 205,235', dated June 25, 1878 application tiled April122, 1878.

To all 'whom it may concern;

Be it known that I, JOSEPH BORDWELL, of Brockport, in the county of' Monroe and State of New York, have invented certain new and useful Improvementsin MowingMachines, of which the following is a specification:

My invention relates to improvements in that class of two-wheeled hinge-jointmowingline of. the driving-wheel, and resembles, in generalrespects, the invention shown and described in Letters Patent of the United States granted to Wm. H; Seymour, March 28, 187 6, No. 175,511'. y objects mainly are to improvesaid patented machine.

The subject-'matter claimed hereinafter speciiicallyT will b'e designated.4 1

In the accompanying drawings, Figure 1 is a planor top'view. of the machine, with the drivin g-wheelz and 'internal spurgearin section to show thegearing; Fig. 2, a" front elevation thereof; Fig', a viewin `elevation,seen from the innergrain,or cutting-apparatus side 'of the machine,"with the. cutting 4'apparatus in section Fig. 4is anlenlargedview, showing a front elevation-'f .the gearing` and adjacent portion ofthe'machinalwith parts in'section; Fig. 5, 'a` similarly-lenlarged'view, showing the pinion thereon, Fig. 6, an enlarged view, showing the shoe in `plan and the .adjacent portions of its connections; Fig. 7 a section on-the line 7 7 of Fig. 6.

Two driving-wheels, A VA', are mounted upon a mainaXle,B, and connected therewith byv backing-ratchets. The inner drive-wheel A is dish-shaped, and' surroundsa portion of the driving-gearing. The backing-ratchet connection between the wheel A and axle is through or byway of an internal. spur-gear, Bf, which isfast upon the axle andindependent of said wheel. The axle .is supported in bearings in` the outside main frame bar or piece VC and theinside bent rod or main framebar C. The drivers seat D andvfoot-board` and toolboXD 4are mounted on the` frame-bar O. The tonguell is? bolted toA the tongue# plate e, pivoted` to rock` on the'` inner main 'A rocking lever, F, secured reanend of the tongue, is pro-` frame-bar G. rigidly'to the.

"connected by a swivel-joint to a down-hanger,

of the mai nc, on the piece C, `below the bar C' frame. The' rear end of the shoe is connected by a link, i, to' aI down-hanger, I, from the frame-bar C. A link, J, pivoted to a lug on the shoe, moves endwise` lthrough a bracket, J i', on the frame, and is provided with a stop,

`bywhich it may be prevented from descending below a given point'when the machine is in operation, and which servesalso (when the cutting apparatus is elevated) to hold the shoe above the ground for transportation.

i The stop to limit the downward movement of the link, as shown, consists ofa pin,V j, projecting transversely through the'linknear its top above the bracket J. lflherY stop may be .made adjustable by providinglseveral holes in thel link,through any one'dof which the pin may be passed, according-'- to =the vdistance it is desired to hold the heel or'shoe end of the cutting apparatus above tlieground, either l when at work orwhen elevated. end ofthe countershaft and the shifting- All the parts, so far as described above, are, both in construction and mode of operation, the corresponding i parts of the machine shown and described in the before-mentioned patent of Wm. H. Seymour.

The iinger-beam, when turned uptoward the mainframe, may be locked by a hook, L,

as in said Seymours patent.

Instead of the lifting devices shown and described in the above-referred-to patent to Seymour, I employ a lever, K, rocking in a vertical path transverse to the iinger-beam,

and at the side of and close to the drivers seat. Thislever is secured to the inner end of a rock-shaft, K', which is mounted in bear-V ings l t', the outer `one formed in the mainframe down-hanger c, and` theV4 inner oneh in the pendent portion or downhangingpart, of

a bracket, M, fast on theLframe-rod G', at the inner sideof thetongue. The rock-shaftex.

Atends'crossn'rise of the tongue beneath the" f plate e, and parallel with the outer end of the bent rod G'. Obviously this rock-shaft might be supported in bearings' formed with the tongue-plate. At its outer end the rock-shaft is formed with an arm or crank, M', to which is secured one end of a chain or other iieXible connection, N, which passes over a'pulley, N', revolving on a stud-shaft projecting from the gearing-supporting portion of the main frame outside the driving-wheel A, and is then connected to a lug on the rear of the shoe H. The pulley is inclined so as to rotate in a path parallel with the line of movement of the lifting-chain. The link J, before mentioned, is straight, or nearly so, for about half or a little more than half its length,'and is then bent outward and backward to the lower end. A stop-pin, j', llimits the upward movement of the link.

From the above description, and by reference to the drawings, it will be seen that in operation the driver, by throwing forward the lever K, rst lifts the heel or shoe end of the cutting apparatus until the stop j strikes the bracket J', if it is desired to llift the shoe to this extent. A continued forward move-ment of the lifting-lever throws up the divider end of the cutting apparatus, and lifts the ngerbeam bodilyT to a position in which the divider is raised considerably above the shoe. The cutting apparatusmay be held in this position by a pivoted horizontally-swinging catch, m, pivoted on the top of the bracket M, and provided with a hook, which engages the liftinglever at its rear and holds it, and through it the finger-beam. When the finger-beam is thrown up. vertically the link J slides downward in the bracket to lower the shoe sufliciently far to enable the hook L to engage the iin gerbeam. It will thus be seen that the lever K serves to rock the finger-beam on its hinged connections with the main frame at the heel end only, if desirable; then to throw up the outer end of the finger-beam; and, finally, to keep the chain taut when the finger-beam is folded up to the side ofthe machine.

To prevent the cutter-bar from sliding or dropping out of place when the nger-beam is inclined or folded up, and yet admit of the withdrawal of the cutter-bar when desired, I provide a stop on the shoe, against which the heel end or-last cutter-blade of the knife abuts when the cutting apparatus is elevated. This stop consists of a pin, O, secured to a spring, O1, and projecting through an opening in the cutter-guideway on the shoe, so as to be in line with the cutters. (See Figs. 6 and 7.) The inner cutter-blade or knife-section O2 is preferably cut away at its edge which strikes against the pin, so as to prevent it from cuttlng or wearing the stop. Normally the stop `is held in its working position by the platespring 01, which is secured at its end opposite that from which the stop projects upon the shoe. The spring, at its free end, may be forced up to withdrawthe stop when the knife-,bar is to be removed or inserted in place.

The internally-toothed gear B' drives the pinion P on the counter-shaft P1, to which is fastened the bevel-gear P2, for driving the crank-shaft pinion Q, and the cutters through the pitman Q', and its connections, as shown and described in the patent of Seymour before referred to.

Instead of the mechanism for throwing the cutters into and ont of operation described in said patent, I make use of the following devices: A weighted rocking lever, R,is provided with a sleeve or collar, R1, having a serpentine groove or cam-slot in it, and turning about an endwise-moving rod, R2. This rod is provided with a lug or pin, r, which enters the slot in the lever-collar, which collar is prevented from moving endwise by bracket-lugs s s', between which the collar is mounted. The lshaft R2 is mounted in bearings in these bracket-lugs above the counter-shaft, so as to be capable of movement endwise parallel with the countershaft. At its inner end the rod R2 is bent downward and forward with a fork or clutchyoke, r', which engages a collar, T, on the loosely-mounted pinion P of the counter-shaft. The clutch engages the pinion-sleeve between the pinion and flange or head of the sleeve, so Ythat the endwise movement of the yokerod is imparted to the pinion. A suitable notch or a cross-cut, t, in the pinion P is engaged by an interlocking` lateral projection or pin, t', on the counter-shaft, when it is desired to engage the shifting pinion P with this shaft. By rocking the lever R forward the pinion is engaged with the counter-shaft, and held so against accidental displacement by the weight U, and by rocking it in the opposite direction the shifting pinion is moved away from the end of the counter-shaft and disengaged therefrom. Endwise movement of the counter-shaft is prevented by the bevelgear P2, the hub of which is inclosed and ts snugly between the uprights V V' of the gearsupporting portion of the main frame. The driver from his seat can quickly throw the cutters into or out of operation by shifting the pinion, which at all times rotates in contact with the internal or main gear.

I claim as my own invention- 1. The combination, substantially as hereinbefore set forth, of the main frame, the cranked rock-shaft mounted in bearings at the front of the main frame, and crossin git transversely to and beneath the tongue in advance of the drivingwvheel, the lifting-lever secured to one end of the rock-shaft, the chain secured to the crank at the outer end of the rock-shaft outside the main frame, the pulley on the gearing portion of the main frame, outside the driving-wheel and above the shoe, over which pulley the chain passes, and the hinged cutting apparatus. t

2. The combination of the frame-bar C, the bent frame-rod C', the down-hanger c, the bracket M, the cranked rock-shaft mounted in bearings beneath the heel of the tongue in said down-hanger and bracket, the liftinglever at the inner side of the tongue, and a iiexible connection between the crank of the rock-shaft and the cutting apparatus, these members being constructed and operating substantially as hereinbefore set forth.

3. The combination of the driving-wheel, the main interna1lytoothed gear, the gearingsupporting portion of the main frame outside the driving-Wheel. the counter-shaft, the shifting pinion movable endWise thereon, and at all times meshing with the main gear, the stop on the counter-shaft end interlocking with the pinion, the endwise-moving clutchrod engaging the pinion, the Weighted shifting-lever, its slotted collar turning above the h.
