EDWARD M. HEYLMAN, OF JANESVILLE, WISCONSIN, ASSIGNOR TO THE' PQRATION.

PLo w.

BG-it'kIiOWil that I,;EnwARn M. HE'YL MALL-a citizen of the UnitedStates, and a resident of Janesville, county of Rock and State of Wisconsin,'have invented certain new and useful Improvements in Plows, of which the following is declared to be a full,

' The inventionirelates to improvements in riding-plows and seeks to rovide a plow which may be raised and owere-d to and fromworking position by the riders feet, so that the riders hands are left free. to guide the team. a

' With a plow which is arranged to be raised and lowered to and from working position by the riders feet it is desirable that all. parts of .the plow should be accurately .balanced and that the plow should enter and leave the ground oint first, so as'to be drawn into and out of t e ground by the draft of theiteam.

Further objects of the invention are to provide suitable means by which the plow is caused to enter'and leave the ground point j first and to provide suitable balancing liftsprings, so that the rider may raise and lower e plow with little effort.

. While features of the invention are applicable to other types of plow, the invention more particularly relates to. that type in low is hung on a cranked or bail shaft, to which shaft thearm of the'land-side wheel is adjustably connectechso that the plow and'landrside wheel shift together to and from working osition, and the plow is thus automatically leveled as it is raised and lowered.

WVith these and other objects'in view, as

will presently appean the invention consists in the features of construction, combinations,

and arrangements of parts hereinafter set forth, illustrated in the accompanying draw ings, and more particularly pointed out in tion of the improved plow. M View thereof; Fig.2 is a detail/of partsthe appended claims.

In the drawings, Figure 1 is a 'side eleva Fig. 2 Tis; a plan g shown in Figs. 1 and 2. Figs; 3,4,5, and 6 are detail sections showing the different positions assumed by the plow as it israised and lowered. Fig. 7 is an elevation of the foot-operated mechanismfor raising and lowering the plow shown in its uppermost p6 s ci catio -of Letters Patent. in ut-man and January 20, 1906. Serial No. 241,923.

same. Fig. 9 is "a detail section of parts shown in Fi 7. Figs. 10 and 11 are views similar to Figs. 7 and 8, showing the footcontrolled mechanism for raising and lowering the plow in its lowermost position. 12 is a perspective viewof the rear end of the plow-frame, showing means for controlling the movement of the plow so that it enters theground point first. Fi 13 1s a plan view of the means for contro ling the furrowwheels. p

The frame 1 of the plow is formed of wrought iron or steel bar set ,on edge and is of irregular outline, as shown in Fi 2. The

rear endofthe frame is contracte and provided with a U-shaped extension 2. areshaped slotted yoke 3 is bolted to the front end of the frame in vertical position and is of usual form to permit the vertical lay of the low-beam. The frame is carrie vu on the ront andrear furrow or caster whee s 4: and 5 and on the land-wheel t3.-

The rear furrow-Wheel 5 is mounted upon the lower bent end of the u right axle or standard 7, which is journaled in a sleeve 8, bolted to the rear end of the U-shaped frame extension 2. Standard 7 is held against longitudinal movement through the sleeve 8 by ting against the ends of the sleeve.

- The front furrow-wheel 4 is mounted upon the lower bent end of the u standard 10, which is ournale in a sleeve 11, bolted to a laterally-projecting extension 12 at the front of the frame. (See Figs. 1 and 2.) The standard 10 is also arranged to turn through the bracket 13, which is mounted upon its upper end, but is held against longitudinal movement thereon by a collar 14 and a bracket 15, which is secured to the standard below and above the bracket 13. The lever 16, pivoted to'the bracket 13, carries a forwardlyextending arm -17 which is connected b a link 18 to the'sleeve 11.. By adjustingt e lever 16 the front end of the frame may beiraised and lowered upon the furrowright axle orcollars 9, secured to the standard and abutwheel standard 10. A' spring-held dog 19'- on. the lever is arranged to engage a notched segment 20 onthe bracket 13 and hold the :lever 16 in adjusted position. A trip 21, pivthe dog by a rod-22. The bracket "15,. fixed oted to the 'endof the lever, is connected to upon the'upper end of the front furrow-Wheel standard 10,-carto the tongue. When, however, the plow is ries a short stud-shaft 23, extending laterallv shaft the team-pole 24 is pivoted. A bracket 25, secured to the bracket in front of the standard 10, carries a slotted arm 26, which extends toward the land side of'the low and is so arranged that the outer end of t e slot is in vertical alinement with the standard 10. An arm 27,fixed to the up er end of the standard 7 of the rear furrow-w eel, projects laterally away from the land side of the plow, and a rod 28 is pivoted at its rear end to the arm 27. The forward upturned end 29 of the rod extends within the slot ofthe arm 26. An arm 30, pivoted at its forward end to the forward end of the bracket 25, is provided with a slot 31, which engages the upturned end 29 of the rod 28. The rear end of the arm is bent inwardly, as shown, and is connected to the forward end ofa spring 32. Spring 32 extends rearwardly from the arm 30 and is connected to a pin 33 on the rod 28. The arm 30 and spring 32 are so dis osedthat they tend to hold the end 29 of t e rod 28 in line with the vertical standard 10 of the front.

caster-wheel,- so thatintheoperation of the plow the side sway of the team is not imparted through the tongue to the rear casterwheel. Moreover, as long-as the tongue extends forwardly the slotted arm 26 1s held substantially at right angles to the rod 28, and the forward thrust'u on the rod, due to the v ressure toward the and, cannot move the ferward end of the rod in the slot of arm 26, and this forward thrust is not ,imparted turned toward the ri ht, slotted arm 26 is swung forwardly (see ig. 13) and into such a posltion as to permit the shift of the forward end of the rod 28 in the slot to permit the rear casterwheel to swing forwardlyL. This shift of the rodstretches the spring 32 so that as soon as the parts assume t eir normal position the upturned end 29 of the rod 28 will be shifted back by the arm 30 and spring 32 into line with the standard 10. In

- turning in the opposite direction arm 26 is swung rearwardly, and the backward ull on rod 28 shifts the upturned end 29 in t e slot ofarm 26 and stretches the spring 32, so that as soon as the team and pole are brought into line straight ahead the pull of the spring on farm 30 Will shift the end of the rod 28 back to its normal position in line with thevertical standardlO. 4

I To the sides of'frame 1, are secured the downwardly-extending brackets 34. and 35,

' within which the main-crank or bailshaft36 is journaled. Between the sides of the frame shaft 36 is offset or bent laterally to form a connected. 7 At the bail3'Z, to which the low beam or beams are land side of the plow shaft 36 extends beyond sleeve 38 is rotatab'ly. mounted upon this extended portion of Y the shaft. An arm 39 on the frame, and a.

BEST AVAlLABLE COP the outer end of sleeve 38 carries an offset sleeve 40, within which the shaft 41 of the I land-wheel is mounted.

A notched segment 42 is fixed to the end of the shaft 36, and a lever 43, fixed to the end of the sleeve 38, carries a spring-pressed dog 44, arranged to en age the notches of segment 42 and adjustab y connect the landwheel sleeve and the bail-shaft. A trip 45, pivoted to the end of the lever 43, is connected to the dog 44 by rod 46. An arm 47, fixed to the inner end of land-wheel sleeve 38, projects forwardly therefrom and is connected to the rear end of a spring ,48. The forward end of the spring 48 is connected to a bracket 49 at the front art of the frame.

Arms 39 an 47 and spring 48 are so disposed that when the axle 41 of the land-wheel is directly below sleeve 38 the arm 47 and the spring Wlll be in line, (see Fig. 2,) so that if t e land wheel is shifted either forward or back to lower the plow-frame spring 48 will be placed under tension and will tend to swing the land-wheel back beneath the sleeve 38, and thus lift the frame and plow. It should be noted that the land-wheel is normally locked to the bail-shaft 36 and shifts there- 'with as the plow is raised and lowered; but the land-wheel can also be shifted independently by the lever 43 when dog 44 is released. In either case, however, the land wheellis always balanced by the lift-spring 48 whatever the osition of the arm 39 with reference tothe ail 37 maybe. a 4

To the land-side arm of the crank '37 isfixed a casting 50, having an upwardly-projectin arm 51, to which is connected theforwar end of the main lift-spring 52. The rear end of the main lift-spring 52 is connected to a lug 53. on a,bracket 54, which is secured to the landside of the frame and at the rear portion thereof.

Lift-spring 52 is arranged to balance the,

weight of the plow or plows carried by the bail 37, while the supplemental lift-spring 48, as described, balances the land-side wheel.

In plow constructions of this type, inwhich the land-side'wheel is connected to shift with the bail as the plow is lowered and raised to and from working position, the force necessary to lift the plow varies with the adjust ment of the land-side wheel'that is to say, if the land-side wheel is in front of the shaft 36 the weight of the plow on bail 37 tends to swing it rearwardlyand lift the frame at this point. If, on the other hand, the land-wheel 1s in the rear of the shaft 36, the weight of the plow tends to depress the frame at this point, so that the power necessary to lift the plow out of theground varies considerably to the relative adjustment between the sleeve 38 of the land-side wheel and the shaft 36. This variable force cannot becompensated' for by a single lift-spring. In accordance with the m seer AVAMeLE cos spring 52, connected to the, bail 37, will always balance the weight of the plow, and the'supplemental lift-spring 48 connected to the lahd-whielsleeve 38', will "always balance .the pressure'onthe land-side wheel whatever the relative adjustment between the land wheel and the bail. .It should be furthernoted that inasmuch as the land side wheel is ordinarily locked to the bail-shaftl'that car-v,

ries the plow the'plow bail-shaft and landsside wheel shift together to andfronr' working position, so that the plow is automatically eveled in the ground. The force necessary to shift, the plow var'ieswith the adjustment of the land-side wheel By employing the supplemental lift-spring, thetension ofwhichvaries withthe adjustment of the land-sidewheel, this compensates for I the different force required to lift the plow, and'the'sups;

pl'eme'ntal lift-spring thus, not only-balances 1 the pressure on-thelandside wheel, but also;

coo erates andassis'ts in turning the ban-y. sha t to lift the plow where itsuse has'been found that the main lift-spring can be weaker than is. ordinarily employed; It is of ar. ticular "importance with a foot mechanisrrr for raising and loweringtheplow that all parts-should be f accurately. balanced and capable, of being ffshifted with little effort,

'since it is not possible to employ-long power' ful levers, as with the ordinary ;-hand mach-' anism; It sh uId be furthefr'neted that the. plow and land id wheelare, in a way, bal- -anced, between the mainlift-spring 52 and;

which it is attached, swings froth-the posi-- tion shown in Fig. 2'-when the plow is raised t the position shown in 1 when the plow is lemma. Gre'ater powermust be exerted tof -startjtheplow from its lowermost position than at a nyother-time, and in this position both the tensionand leverage of the supplemental lift-spring are greatest, .sothat for the iminished leverage o the ma -1 ftthe sup lemental lift,-'sprin1 compensates s ring. Ifl'the main lift-spring were usedi a one, it would have to be very heavy wto start the low from the ground, and it would. be difiicu t to push the plowintothe ground against the tension of such a heav-"y spring.

.By employing. the supplemental lift-spring,

the tension. and leverage of which is greatest I when the plow is, lowered'and which tension and. leverage rapidl diminishes as the/plow I is raised, alight mam lift-spring may be emfployed, and in consequence the plowmay be veryeasily forced into the. ground.

In the drawings a gan ,lowis shown hav ing two plow-beams; but 1t isobvious that a Oct-lever .77 and a 1n the teeth 82 .onthe segr n lever 77 it is first s single plowcould-be emplomd, fififdesired. The main low-beam 55 carriesthe'plow,56 and exten s forwardly through the yoke 3 and carries a suitable clevis 57'at' its forward end. The supplemental plowrbeam 58 cararies the .pl'ow 59', and its-forwardend is bent l terally and connected to a; bracket 60, lted to the plow-lrea1n-55. Abra'ce 61 is boltedfto the; rearend of the plow beam '55 and extends aterallythrough a bracket 62,

I The plow-beams are pivotall connected to the bail byi'means 'of'the brackets '65 and :56,-se'curely bolted to the beams, extending downwardly therefrom,- and j ournaled on the ba'i i,

Bracket 35 onthe land side of the frame is provided with an upwardly-extending por 'tion 67, Within which is: mounted a short hol low shaft 68.;"(Se Fig. 9.) The' inner end of the. hollowshaft- 68 is square and carries a 'bel'l l crank 69; The lowerarm 70 of the bellcrank is connectediby a link 71 with the for- ,wardl-y and downwardl I extending lug 72 on the bracket 50. Brae et 50, as above de scribedyis fixed to the land-side arm of the bail;37. The outer end of the hollow shaft 68 is'provided with a head 73, having'a series of radial notches andengaging a correspondingly-notched head on the end of a foot-lever 7 4. A bolt 75 extends through the hollow shaft '68 and securely clamps foot-lever 7.4

and bell-crank 69 thereto.

To the upper arm 76 of the "bell-crank 69 is ivoted a foot-lever 77, which carries a lockmg pawl or dog 78, arranged to engage a seg-, -ment 7 9, formedu on the upper end of the bracket 67. In -t e raised ortion ofthe low a spring 80, interpose between the on the arm 76, ent'withone of I I 79, so that the low is locked in raised "position, asshown in igs; 7 and, 8.

part 77 are, in effect, a single-jointed foot-1e ver for depressing the plow into the ground,

. the outer section of which is'provided with a ground. If the bolt 83 is screwed in so as to engage the stop 84 before the arm 70 and link 71 reach the. dead-center position, the plow will not be locked in the ground, but will be free to raise when it meets a stone or other obstruction. I

The riders seat 85 is carried upon a spring 86, secured to the bracket 54 at the rear of In this position the foot-

levers

74 and 77 will be in easy reach of the rider. It should be noted that the lifting foot-lever 74 extends rearwardly from its pivot-point toward the riders seat, so that it is in such a position that the lift mechanism may be easily operated by the direct downward pressure of the riders foot. When the low is raised, the spring 80 presses the locking-dog 78 into engagement with the teeth 82 and automatically locks the plow in raised position. Two or more of the teeth 82 are preferably provided and are so arranged that the plow may be held clear of the ground without lifting it to its extreme uppermost position. This latter arrangement is a convenience if the operator desires to hold the low out of the ground for a little while or if t e machine is operated by a boy or other rider with short It should be noted that the link which con nects the foot-levers with the plow-bail is pivoted to the bracket 50 on the bail in front of and below the bail, so that a powerful leveil'age is obtained in raising and lowering the The foot mechanism for raising and lowering the plow and the lift-spring are connected to the bail, so that the plow is free to oscillate on the bail when in operation.

To the rear of the main plow-beam is secured a bracket 87, which projects upwardly and rearwardly therefrom and is provided with a slot 88. Bracket 89 is secured to the rear U-shapedportion ofthe frame opposite the seat-bracket 54. Brackets 54 and 89 are provided at their rear ends with downwardly and rearwardly extending lugs 90, to and between which is journaled the swinging arm 91. The inner end of the arm is forked, as shown in FigsXZ and 12, and extends oneither side of the bracket 87 on the plowbean1. A

' an operatin -shoulder 96 above the fixed stop sssr AVAILABLE cop.

cross bolt or pivot 92 extends between the forked portions of arm 91 and through the slot 88 of the bracket 87. The bolt 92, extending through the slot 86 of the bracket, forms a lost-motion connection between the arm 91 and the bracket 87-i. e., a connection which permits of a relative shift between the connected parts, for the purpose herein after stated. The arm 91 is rovided with a laterally-extending lu 93, which is arranged to cooperate with the ed stop 94 and movable stop 95,'mounted upon the frame. The movable stop 95 is referably in the form ofthe arm pivoted to t e bracket 89 and having 94. A coile spring 97, interposed between the stop 94 and the lu 98 on the lower end of the stop 95, normally olds the same into engagement with the stop 94. Alaterally-extending lug 99 (see Figs. 2 and 12) on the end of the bracket 87 is arranged to 006 erate with the upper end of the stop 95, as ereinafter described.

In Fig. 3 the parts are shown in position with the plow raised. In this position pin 92 on arm 91 is in the forward end of the slot 88 in the bracket 87. As the plow-bail 37 is swung forwardly and downwardly to lower the plow, arm 91 also swings forwardly and downwardly until arrested by the enga ement of the lug 93 thereon with the shoul er 96 of the stop 95. (See Fig. 4.) By this means the downward movement of the rear end of the low is arrestedthat is to say, the heel of t e plow is held up. The forward movement, however, of the rear end of the plow is not checked when the movement of arm 91 is arrested because of the lost-motion connection between the bracket 87 and the arm 91, and as the plow-bail 37 continues its forward and downward swing the point of the plow is depressed, so that the plow enters the ground point first, as most clearly shown in Fig. 5. This continued forward movement of the plow brings the lug 99 on the bracket .87 into engagement with the upper end of the stop 95, moves it against the resistance of the spring 97, and shifts its shoulder 96 out from beneath the stop 93 on the arm 91, as indicated in Fig. 5. As soon as the shoulder 96 is completely shifted from beneath the stop 93 the rear end or heel of theplow drops until the stop 93 on the arm 91 engages the fixed stop 94 on the machineframe. In this position the plow is held level in the furrow, as indicated in Fig. 1. As the plow-bail starts to swing upwardly and backwardly the point of the plow will be first raised, as indicated in Fig. 6, so that the plow leaves the ground point first. The continued upward and backward swing will raise the plow to its full height and shift the arm 9 1 to the position shown in Fig. 3, with the lug 93 thereon above the shoulder on stop 95.

By causing the plow to enter and leave the arm of the land-side wheel is adjustably ground point first the draft of the team is brought into pla to force the plow into the ground and to draw it out, so thatlittle effort is necessary on the part of the operator to raise and lower the plow through the medium of the foot-levers. The foot mechanism is also made very easy to operate, since both the plow and land-wheel are accurately balanced by the peculiar arrangement of main and supp emental lift-springs. In other plows of th s structure a-differential mechanism has .been employed for controlling the movement of the plow and cause it to enter and leave the ground point first; but the essential feature of this part of my invention consists in providing'aj relatively fixed stop on the frame of the machine, which is arranged to hold u the heel of the plow as the latter is lowere together with means for automatically releasing the rear end of the plow from the stop, so as to I level the plow in the ground. As stated, the features of the invention relate more particularly to the type of ridin or wheel plow in which the plow is carrie upon a crank shaft or bail, to which shaft. the depending connected. The land-side wheel, bail, and plow are shifted together to and fro'm working position, so that the plow is automatically leveled, both in working and riding positions. The force necessary to shift such a plow is greater than if the land-side wheel and plow are moved independently, and considarable difficult "has been encountered: in providing footift mechanism (in which the the leverage is-neces'sarily less thanin the hand-lift mechanism) for manipulating; this type of plow. I, however, have provided main and supplemental .liftsprings, the ten-- sion of which latter varies with the adjustment of the land-side wheel, and which cooperate .to balance the entire plow structure and land-side wheel, and both assist inlifting the plow. Moreover, I have provided a suit--- able stop device for upholding the heel of the plow as the latter is lowered, so that the plow enters the round point first, and'which is I automaticaly-tripped' on the continued for? ward movement of the plow to level the plow in the grou'ndand to permit it to leave the ground point'first, so that the team'assist'sin shifting the plow to and from working position. By the combination of such devices I have been able to provide a foot-lift mechanism which will readily and easily. inanipu late a plow of the type'mentioned'. Moreover, the foot mechanism and lift-spring are connected to the cranked .part of the plowbail, so that the plow is free to oscillate onits .pivotal connection with the'bail when in the round. Furthermore, the raisin andliftmg foot-levers are pivoted on'the,

amgfand extend in' opposite directlons, the 11 tmg foot-lever extending'rearwardly toward the riders seat, so that the operatormay nicely L arra ed to engage said lug and hol seer AVAlLABLE cos control the plow by placing one foot on each lever and may exert pressure to advantage on either lever, and articularly on the li ing foot-lever to shift the plow. v

t is obvious that numerous changes may be made in the details of structure without departure from the essentials of the inven" tion.
