IMPROVEMENT IN GANG-#FLOWS l MMM The Schedule referred to in these Letters `Patent: and making part o f the same.

To all whom it may concern.-

Beit known that I, J.` XV. Lewis, of Oregon City, in the county of Clackamas, and State of Oregon, have invented a new and useful Lmprovement in Gangfollowing is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, forming a part of this specication.

Thisiinvention consists in the novel construction of a gan g-xplow, whereby ellicien'cy, durability, and cheap- Figure 1, in the accompanying drawings, represents a, longitudinal section ofa gang-plow, constructed according to my invention; and

Figure 2, a pian view of the same.

Figure 3 represents a transversey sectional view of the axle, with one wheel attached, showing a device employed in effecting verticafadustmentef the axle",- and Figure 4 represents right angles thereto.

Similar letters of reference. indicate corresponding parts in the several figures.

A is an axle, mounted upon two wheels, B B, and

another view of fig. 3, taken at provided with a tongue, G, substantially as other gangf plows.

Erected over' said axleA is the ordinary drivers seat D.

Within the frame which supports this seat, is provided a vertical guide-way or slot, a, within which is arranged, to slide up and down, a connecting-bolt, b, which passes transversely and in a horizontal direction through the front ends of two beams, E E. Said beamsarc hung to and dragged behind the above-described currele, by means of the said connection of the bolt b with the slot or guideway d.

The beams E E are provided with are connected to each other by any suitable means, so as to leare sufeient space between them forY the proper separation of the plows. A

The rear portion ofthe tongue O is divided or bi-` pronged, and with suliicient space between said prongs for reception cfa level', G.

Said lever G is horizontally arranged,rand pivoted between the prongs of the tongue, at a point, c, in

Vfront ofthe axle, and with its rearyend in position for operating i gainstor under a friction-roller, e, attached between the. beams E E.

4 Said friction-roller c is located atasuitable distance behind the connecting-holte, for obtaining the most satislirctory results inl raising the said beams and disengaging the plows from the ground, say, at a point,

9:, in the drawings.

lhe front portion of this lever G carries a frictionroller, g, and is, furthermore, divided or lli-pronged, for reception, behind the said friction-roller g, of a curved arm, f.

Said curved arm f is attached to the lower` extremplows,-Ii F, and v ity of a vertically-arranged .hand-lever, H, so as to act against the rear and upper sides of the said frictionroller g, by the backward movement ofthe said hand- ,lever, while a ldili'erent but similarly-acting arm, Lf', also attached to the lower extremity of the same lever, comes in contact with the said frietion-roller from the front, and passes under the saine, so as to act against the front and under sides of the said roller bythe forward movement of the lever,so that `the forward and backward movements oi said hand-lever will cause the oscillation of said lever,'thereby raising aud lowering the beams E,-.tog'ether with the plows F.

`Assistance may be rendered the plows to enter the ground more readily, when desirable, by means of a diction-roller, c', which :is suspended in a swinging frame, immediately below the roller e, and against which the lower side of the rear end'of the lever G'v acts, by'tlie'frivard movement ofth'e flan'ddever'H;

The axleA is not supplied with rigidly-attached i arms or spindles for the wheels,- as isusually the case, but issu'pplied with adjustable arms or spindles, o o, whereby a means 'of vertical -adlustment is given 'to the said axle, for the purpose of varying, when desirable, the depth of penetration ofthe plows.

Said vertical adjustment is eectcd by means of a vertical slider, an, secured upon the shoulderofthc arm o, and fitted toslide between lips n, forming a Vsuitable guideway upon the extremity of t-he axle A, so that the sliding of the parts will cause the raising or lowering of the said arm o, relatively to the axle A, or a similar movement of the `said axle relatively tothe arm, when said arm is being supported upon ythe wheel. l

, Said slider m is provided with a rectangular forward extension', p, together with an upwardly-curved for ward extension, p

' lo the forward .extremity of the said rectangular fbrward extension p, is pivoted, through its lower cxtreinity, a vertical or nearly vertical hand-lever;, fr, so as thereby to allow the said hand-lever a forward and backward movement, while it is guided, atthe same timein said, movements, by a lip, s, secured thereon, and fitting over the upwardly-curved formation p' of the said slider m.

The said hand-lever ris provided, at its lower extremity, with a rectangular'rearward extension or arm, fr. Said arm r is oi' a corresponding length with tbe rectangular forward extension p of the slider fm, and is connected with the upper side of the extremity of the axle A, orl to the upper part of the guideway n, by means of a hingedlink, or short toggle-lever, q, so that thev forward or backward movement of the .handlever lr will cause the raising or lowering of the axle.

` rl.he axle is retained at its dili'erent degrees of ad` justment, which may be thus given to it, by means.

of a spring locking-lever, V,arranged on the outside of the hand-lever lr, and lengthwise thereof.

Said locking-lever V is pivoted upon the said hand,

lever fr, by a pin passing through it and through ears, u, upon the said hand-lever, near its central portion; and it is provided at its lower extremity with a rectangular inward projection or locking-pin, V, which passes through an opening in the lip s, and into any one of a series of holes, t', near the edge of the curved extension p' of the slider m.

For raising or loweri-ng the axle, and thereby varyf ing the depth of penetration ofthe plows in the ground,

the upper extremities of the two levers o' and V, which are arranged side by side, are taken at the same time, and so grasped by the hand as to force the lockinglever V towards the hand-lever r, thereby unlocking the said hand-lever bythe withdrawal of the locking` pin Vfrom the hole 1', in which it may be locked,`

when, by a forward or backward movement of said l hand-lever, the axle may be raised or lowered atpleas-'` ure. By relaxing the grasp,'after saidadjustment has been eli'ected, the locking-lever V is forced outward by the actionof a spring, z, forcing the locking-piu V" into any one ot' the holes "i which may be oppositeto it, thereby locking the hand-lever ll', and retaining the axle at said adjustment. f i 1 The' application of a device, similar to the one above described, is necessary 'at each end Aof'the axle, and

operated by both hands simultaneously, to insure a uniform adjustment of both extremities of the said axle. l

la k are cutters, so secured to the dat side of the plows F F as to present a cutting-front to said plows,

' for the separating or cutting asunderof roots, or other impediments, which may li'e in the line of theircourse, and are or may be screwed, or bolted, or otherwise secured Ato the plows, so as to be easily removed for any desirable purpose.

These cutters 7c k are. provided with curvilinearlyformed edges, for more readilycutting or separat-ing.

'said roots, or other obstaclesrand also, with their .upper extremities of a laterally-curved formation to outline.

Said 'raised condition of the front ends of the said beams places the plows in a position for'cuttingvtheir way out of the ground, and a further backward move ment of the said lever H will cause the points of the plows to be raised above Athe surface ofthe ground.

The position of the beams E, while in thisI condition, may be reversed bythe pressing of the foot. of the driver upon a horizontally and forwardly-projecting foot-lever, I, attached to the forward ends of thebeams E. Said pressing of the foot upon the lever I causes the beams to turn upon the friction-roll`er eas a fulcrnm', thereby directing the points of the plows downward, so as to be in position for entering the ground upon the'forward movement ofthe said lever.

What'Iclaim as my invention, and desire to have secured by Letters Patent, is-f 1. The l1oistinglever.G of a gang-plow, arranged for operation, in connection with the hand'lever H, for raising theplows, substantially as herein described.

2. The curved extremities or arms f f', in combination with the hand-leverHand hoistinglever G, substantially as and for the purpose herein set forth.

3'. The swinging flame, andv roller e', in combination with the beams E, aud level-2 G, substantially as and for the purpose herein set forth. y
