HARVESTER.

SPECIFICATION forming part of Letters Patent No. 272,217, dated February 13, 1883.

Application filed October 1G, 1882. (No model.)

To alt trimm it 'may concern:

Be it known that I, JOHN S. DAVIS, of Toledo, in the county ofLucas and State ot Ohio, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

My objects mainly are to provide a strong, light, and durable machine, and to enable the driver readily to control its operation.

As shown by the accompanying drawings, my invention is applied to a mower or grasscutting harvester. -Some of my improvements may advantageously be used without the others, and in connection with either grass or grain harvesters.

Figure l is a plan or top view with parts broken away. Fig. 2 is a side elevation with .parts broken away, other partsin section, and some parts detached. Fig. 3 is a front elevazo tion, with the tongue in section. Fig. 4 is a View, partly in side elevation and partly in scction on or about the line 4 4 of Fig. 1. Fig. 5 is aside elevation, showing details of thedevices for throwing the cutter-actuating gearing into and out of action. Fig. 6 isa plan View of the box or bearing-sleeve for connecting the pitman and wrist-pin ofthe crank-wheel. Fig.

7 is a view in section on the line 7 7 of Figs. l-

and 6, showing' details of the connection between the pitman and wrist-pin boX. Figs. S

and 9 are respectively a side elevation and a plan view ot' the shoe detached. Figs. l() and 11 are respectively a side elevation and a plan view ot an eccentric by the oscillation ot' which the shoe is rocked. Fig. 12-is a plan view ot' the adjustable bracket and its turning eyebolt for connecting the drag-bar and main-frame arm.

A two-part main frame, A B, of substantially 4o rectangular form, is provided at its front inner corner with an inwardly-projecting arm or side extension, A. This arm crosses in advance of and extends inside of the inner one of a pair of driving-wheels, B B2, which are looselymounted on their axle A2. The art A of the mainframe and the arm A', as shown,

are formed of one piecel ot' wrought-iron, consisting of a bar bent into shape and riveted at a, one end of the bar extending slightly for- 5o ward frotn'the innervfront corner ofthe frame proper, and being bent rst downward and then inward to form the side arm, A', crossing beneath the tongue B3. The tongue extends back by the side ofthe frame, and is strongly securedto the inner side thereof by bolts ain this instance three in'number. Another bolt, c2, connects thetongue and arm A of the `frame. Strength and stiffness are in this way attained. The portion B ofthe main frame is forked, is of cast-iron, and constitutes abedpiece which supports the gearing, and is provided with the boxesfor the axle and gear-shaft ing. This bedpieee is fitted to the bent tra mebar A and mainly within it. Bolts b b b b2 b2,

i Figs. 1 and 3. passing through suitable iianges of the bed-piece, serve to firmly unite it with the frame-bar. Byvtorking the bed-piece, as shown, desired strength without unnecessary weight is secured. The axle turns freely in -sectional boxes a3 a3, and the driving-wheels are connected with the axle by backing-ratchets, or so as to cause it to turn therewith when the machine is advancing and leave it free w hen backing. The ratchets U O are fastened tothe axle, and spring-pawls c, for engagement therewith, are pivoted to spokes ofthe drivingwheels. The ratchet O for the outer drivingwheel, and an internally-toothed driving-gear, 1 A

D, are rigidly connected, either by casting them together or making them separately and firmly uniting them. They are best made'in one casting and connected by spokes, as shown.

A pinion, D', is loosely mounted on a shaft, E, supported in sectional boxes c c by the bedpiece B. The pinion is driven by the gear D, and engaged with and disengaged from its shaft by suitable clutch mechanism to throw the cutters into and out of gear. As shown, the shaft E has a tixedly-attached cross-pin, d, at its outer end, with which the pinion is adapted to be engaged, to clutch it to its shaft, by cross-grooves-in the pinion-tace, into which the pinion takes, as is well understood, when the pinion is slid toward the end of the shaft and against the pin. The pinion isislid into and out of engagement with the shaft-pin by clutch-shipping mechanism, shown as formed by a forkended lever or rocking shipper, F, engaging acollar on thepinion-hnb and mounted on a supporting arm or bracket, F,secured IOC to the bed-piece bythe bolts which secure the upper section ofthe box e in place. A pivotbolt or headed pin, j', for the shipper` is provided with a spring,f', acting with a tendency to hold a stop-lugj'z, on the shipper against movement outward or away from the upperend of the bracket F". The stop f2 holds the shipper against accidental movement, and so te tains the pinion out of or in clutch with its shaft, according to the position ot' the shipper and whether the stop is bearing against the outside of the bracket, as shown, or against the opposite side thereof.

A bevel-pinion, G, on the crank-shaft G' is driven b v abevel-gear, l1,on the shaft E. The crank-shalt is tnonnted in sectional boxes gg'. rlhe box g' anti the other boxes of' themachine are so constructed and packed as to admit ot' adjustment to take up wear. The box g' is vertically divided, aml is provided with two sets of bolt-lugs or securing-ears, g2 g2, for an obvious` purpose. The packing material (leather, sheetmetal, Stc.) G2 is secured between the box-sections to the thickness needed.

A drivets seat, H, is so mounted as to be located directly over the axle Az. thus rendering variations in the weights ot' drivers or the presence ot' a driver in his seat immaterial in balancing the machine or adjusting the weight on the neck-yoke. The seat-spring is shown as double, consisting otthe stem or main part H' and the leat'H2. A bracket, It, secured to the trout ot' the main frame by side lugs and bolts, h'h', connecting it with the frame-bar A, serves to connect the seat-spring with the frame. A bolt, h2, unites the spring and bracket. Thedownwardly-extendedforwardly-bent end of the spring supports a toolbox and footrest, I. The spring-securing bracket has side tianges, 'i i', to provide a seat or socket for the better attachment ofthe seat-spring. A stoplug or hook-like proiection, t', on the bracket is shown as formed with the llange i'. rlhis stop serves to engage a lever, l', as farther on explained.

The side arm, A', ofthe main frame is braced against downward strains by an inclined bar or bracing-strap, J, secured at one end to the tongue by the bolt a2, and boltedor riveted at its oppositeend to the frame-arm. An inclined brace, J', extends forward from tlte frame-arm to the tongue. This brace-rod is adjus'ably connected to the under side ot' the tongue by means of a bracket, J2, secured in place by a side tlange,j, anda bolt, 7", and its nut. The forward end of the brace-rod is threaded, passes through a perforation in a rib on the under side ot the bracket, and is held by nuts on each side ot' the rib. (See Figs. 1 and 3.)

The rear end ot' thel rod is connected with the frame-arm, near its outer end, by a bolt,j2.

A vet-ticaily-vibrating and axially rocking drag-bar, K, hasjointed connection at one end with the trame-extension or side atm. A', and extends back outside of and parallel, or nearly so, with the face ot" the inner driving-wheel.

To provide for the rocking of the drag-bar about its longitudinal axis, adapt it to vibrate vertically, and provide for readily tilting the parts together, the connection between the drag-bar and traute is iliade as follows: A bracket, K', is formed with an edge tiange. It', to bear against the front edge ot' the framearm, with a slot, k', by which it is adjustably held to the frame-arm by the boltf', an l with a socket or bearing, k2, for a turning eyebolt or swivel-link, liz, secured to the drag-bar by being passed through an eye therein. The bracket is secured to the under side ofthe frame-arm. In this way, as will be obvious, the drag-bar may be vibrated about the framearm by raising and lowering its rear end, and it is rocked axially by means ot' the lever I', which crosses above the drag-bar, and is pivoa-.tlly connected to it by means of the upwardly-projecting lugs l l ot' a bracket, L, bolted to the underside ofthe drag-bar. These lugs extend up at thtl outer edge ot the dragbar, ami a pitt or bolt serves to connect; the lever with them. The rocking lever extends toward the foot-rest, in front ot' the inner drivingwheel and beneath the tongue, and is bent upward and then horizontally, or nearly so, terminating near the outer driving-wheel in a. foot-rest or curve, L', convenient to the foot of the driver while in his seat. The tongue serves to prevent too great upward movement of this lever when the drag-bar rocks in one direction, while the stop t" serves to hold the lever at the limit of its downward movement when the drag-bar is rocked in the opposite direction, for [urposes farther on to be explained. At its rear end the drag-barK passes beneath a `shoe, M, and is then bent upwardly and jointed to the heel of the shoe. A bearing sleeve or socket, M', at the npturned rear end ot' the drag-bar, lugs m m on the shoe-heel,

and a pivot-pinna', serve to make thejointt-d connection between the shoe and trat-bar. The shoe is made to vibrate vertically byrocking it about its heel-pivot; by the means and in the manner next to be described.

Atitst'orward end theshoeprtectsupwardly, and terminates in a bearing ring or socket, N, l'or an eccentric, shown as formed by a disk, N2, and a piti, n, rigidly but detachably connected with it nearits periphery, and constituting tite shaft about which it is rocked in the shoebearing. A hollow eccentric stand and bracket-housiug, N',is tirmly connected by its tianged base ami bolts to the drag-bar. A rear opening, fn', in the housing serves to admit the front etnl ot the shoe, with the eccentric-disk in place, (bet'ore hinging the shoe-heel to the drag-bar and without the pin u,) and a front opening;

n2.in tlte housing accommodates a rod, O, which is pivotally connected with a short arm or ear, o, on the eccentric. At'ter the parts are adjusted tlte pitt n is driven tightly in place. Slots U' (only one ot' which is shown) are made opposite each other in the side walls ot' the housing, for the eccentric-axis to playin as loq IIO

Ils

the eccentric is rocked by the manipulation of the rod O by means such as soon to bey described. This rod is connected by its beltt rear end with the eccentric-arm before the eccentric and shoe are inserted in the housing. Disconnection of therod is preventedv by its contact with the adjacent wallet' the housing. A side lug or dog, o', on the eccentric-arm o comes in contact witha stop-lug or shoulder, 02, on the eccentric-bearing, to litnit the rock of the shoe upward at its front'by the oscillation ofthe eccelltricin thedirection in which it isturued by pulling strain on the rod 0. rEhe downward movement of the front. end ot' the shoe, as` the shoe is vibrated aboutits heelpivot by the thrust of the rod O, is limited by contact of the shoe withv the drag-bar.v

. A shoe-tilting lever, O', connected with the rod O, is pivoted upon astaud or bracket, O, which is secured to the frame-arm A by its flanged base and the boltjz, which secures the drag-bar bracket K and brace-rod J to the frame-arm. rlhe tilting lever is provided with suitable detent devices, shown as consisting otl the rack-teeth l?,v formed with the bracket O2,and the controllingrod P", connected with the spring-actuated rocking stop-lug or donr p, pivoted to the lever to engage the rack. The lever O is adj ustably connected with the rod 0 in sttch manner as ot admit of the turning of this rod to accommodate the axial rocking movement. of the drag-bar K. A socketed screw-threaded coupling-sleeve, p', h'tted to the piti or bent end p2 of the lever by its socket and the threaded endof'the-rod O, ,is screwed into the sleeve.

An inclined rod, Q, connected at its oppothe drag-bar, and a perforated lug, q, on the housing receives the threaded rear end of the brace-rod, which is secured byjam-nuts ou op-.. A linger-beam, Q', is.

postte sides of the lug. rigidly secured at its heel end to theshoe-'in suitable way, and is provided with the usual guards and cutters ,to completeA well-known' cutting apparatus.

A hinged brace-bar or coupling-arm, R, cou-` nects the cutting apparatus withv the outer rear corner ofthe main trame', as will fartherv on 4be fully explained.

Frotn the above description it will be seenV that while the outer end of the cutting appa-v ratus is prevented from dropping too low by contact of the lever l with the under side `of the tongue, or by thepressure of the drivers,

foot, the usually employed device for stiftening thelnger-beatn preparatorytto raising its` outer end is dispensed with, and the outer,

end of the cutting apparatus raised simplyfby depressing the treadle end of the lever l', and

so vrocking the drag-bar. It will further beseen. that in addition to the facility ai'orded the driver lor tilting the guards by the employment of theecceutric, &c., the cutting apparatus is very strongly braced against back ward strains by means of the extended front. end ofthe'sh'oe, the housing in which it works,

and a shoulder or-projection, q', on the shoeA which,fby contact with the wall of the bons-- ing, lessens the strain upon the shoe front or eccentric-bearing arising` fromv backward or thrusting strains on the cutting apparatus.

The coupling-arm R is pin-jointed at itsheel end to lugs Trot' the main frame. Theselugs are formed with lthe rearwardly-projectin g. portion ofthe bed-piece ofthe fratrie near the outer rear corner ot' the bent frame-bar. The connection` between the outer end of the couplingarrn and the cutting apparatus is by way ot' short arms. or lugsvR r on the front portion ot' the shoe. The coupling-arm is pinjointed to thosev lugs, one of which is made longer than the other, and provided witha recess or halfround groove, s, initstop, (see Fig'. 9.) so that when the cutting apparatus is elevated for transportation itv may beheld up by a piu or bolt passing through a hole, S, in the couplingarm and engagingthe-grooves ofthe arm R.-

The cutting apparatus is raisedand. lowered .bodilyor throughoutitsentirelength by mea-ns 'of a rocking lifting-lever, T,ilexibl v connected with the coupling-arm. This lever ismou'nted at or near thel inner rear corner of the main framethroughor by way of the heel end of the tongue. hook, t,.and segmeutsheave t, and is pivoted at t2 to a frame-stand or bracket, T', which is secured by its flanged base and the rearmo'st The lever is provided witha IOO oneof the bolts ct'to the tongue-heelaud fraruebar. A chain, T2, connects the lever-hook and thecoupling-artn. t The lever, when rocked forward and downwardto the limit of its movementin raising the cutting apparatus, engages`v with a catch-bar or detent formed by the hook or. catch u of a exible bar or strap iron, U, se-

A side lugvor latcrankfwheel V bythe-ans of a threaded coupling-sleeve, V2, into which the threaded-end of' the pitman is screwed and held by alam-uut,

c2, and a box or bearing-sleeve, V3, ittingthe wrist-piu and pivoted to its coupling-sleeve. The boxV3 is provided .with an oil-hole,`and held to the wrist-piti bya nut and washer, as usual, and has a perforated ear. 113, which titsA between corresponding ears, V4 V4, on the coupling-sleeve. A tubular pivot-pin, 114, pref erably made of wood, to serve as au inexpensive and readily-removable bushingand pre-rv ventA noise, passes through the holes in the ears ot the coupling-sleeve andbox, and is re- Iltnovablyheld to its place by a screwbolt, 115,'

with its nut and washers.

l do not herein `claim the above-described means for connecting the pitman and crankwheel.

The pitman is connected with the knife-heel or inner end of the cutter-bar by a ball-audsocketjoiut in the following way: The inner sectionor heel attachment, W, of the knifebar has the hollow ball w formed with it, and the pitman is forked or split, and each of the two arms W W of the fork is provided with a half socket or cup, w, which embrace the ball and are caused to properly clasp it by means of the adjusting screw-bolt w2 and its nut. One. of the jaws or arms W of the pitman is threaded for engagement by the screw of the bolt, so that the arms may be separated or drawn together, as desired, and when adjusted be held, with the aid of the jam-nut, on the bolt end. In this way wear may be compensatedfor readily. Oil-holes are drilled in the opposite sides of the ball te, where itis embraced hy the cups w ui', and an opening is made through the top ofthe ball, so that it may be filled with lubricant (oil and cotton waste, tallow, cbc.) to keep thejointlubricated without waste.
