To a/Z whom/'it may'conc-97%.-A

Be it known that LRICHARD B. FENTEM, a

citizen ofthe United States, residing atNewf man, in the county of Stanislaus and State `of California, have inventedcertain new and use ful Improvementsin Land-Gages for Plows; and I do hereby declare the following to be a full, clear, and exact description ofsaid invention, such as will enable others skilled in the art to which it most nearlyappertai ns to make, use, and practice the same. y v

This invention relates to improvements in and more particularly .to land-gages therefor; and it consists in the novel construc-A tion and arrangement of the various parts, as hereinafter described.

In the drawings, Figure l isa plan lView of l the invention as applied to a plow-frame of the gear, the

gang-plow type, the frame of the plow being shown in dotted lines and partly cut away to accommodate the figures of the other drawings. Fig. 2 isla detail view of the runningdraft-be-am of the plow being shown Fig. 3 is a'rear elevation lof the operating-lever.V Fig. 4 is a side view ofthe operating-lever, showing the end of the connecting-rod attached thereto.

The presentinvention applies more particularly to that type of plow known as gangin section.

plows, wherein a number of plows are carried;

'The motive power, is, for this class of upon the same frame. whether horse or engine,

implements much greater than that used for the ordinary single plow. The shifting of the land-gageis therefore much more difficult. of accomplishment in this classof implements.

The spread Vin operating plowsfof the gan gf plow type is muchgreater than inthe single plow, and therefore the extent of the movement of the usual land-,gage would be proportionally greater. It is to accommodate these necessities by providing a land-gage easy of adjustment under a heavy loadand sensitive to a diminished movement that is the object of the 'present invention.

VTo facilitate thedescription of Athe invention with reference tothe drawings, I will let the letter A designate the draft-bar, to'which the motive power -isv attached. The attach-Y nient of the draft-bar is by means of the draftchain B. The chainV is attached to the contracted eyes A A', which are of Ausual construction, to permit the links of the chain to' extend ed gewise between the contracted sides ofthe loop, while/preventing them passing between the same in a crosswise position. l

4 lThe draft-bar A is elongated to throw the points of the attachment of the draft-chain toward the extreme ends of the draft-beam C.

The draft-beam C Vforms a part of the frame of the plow and'extends across the fuli spread of operation of the plows constituting the gang.

The frameshown in` the drawings is preferably constructed from steel Lbeams, and the front beam, called the draft-beam, is provided on the rear-side with a wooden facing C', which fits snugly within the channel between the flanges on that side of the beam. 'lhe wooden facing is secured in place upon the beam by means of the threaded studs C2, which are extended through perforations in the woodenfacing and the web of the beam The studs C2 are welded or firmly atl tached to the metal rod C3, which constitutes in this invention a track for the operation of the land-gage. Vh'en the studs C2 are inv serted through the perforations in the wooden facing and the beam, as mentioned, the outer ends are provided withthe nutsV O4, which when. ,set draw the studs, the rod, and the wooden facing snugly and firmly into position. Upon the rod C3. the carriage D operates. The carriage D consists of the grooved wheels `D D', which are journaled in the ends of stirrups D2 D2. These are maintained separated by a spreader-bar D3, which is provided with perforations D4 for various adjustments for the separation of the stirrups and wheels.

The forward end of the stirrups is clamped Aover the draft-bar A, perforations A2 being 'provided in thel draft-bar to accommodate dierent adjustments. They are secured in position upon the draft-bar by screw-threaded bolts and nuts A3. The bolts A3 are in pairs, so as to hold the stirrups rigidly and perpendicularly to the draft-bar.

Vhen constructed as described thus far,

'the draft bar and chain are connected to the 'draft-beam through a carriage which is mounted upon a track to move fromvend to end upon` the draft-beam. `It is tocontrol this movement and to lock the carriage in the .desired positions to which it is moved that I have provided the lever E and the interme- IOO 7 position.

diate connections between the said lever and the carriage.

The lever E is pivotally mounted upon what is termed the land-beam of the plow, a continuous threaded bolt E being provided to extend through a suitable perforation, with nuts set upon either side of the web of the land-beam and having a smooth portion of the said bolt extending beyond the threaded portion to form a pivot for the said lever. A Cotter-pin is used to hold the lever upon the pivotal part of the bolt when the lever is in The leveris provided with a guidebracket E2, the end of which is depended to form a guide for the lever E in its operation over the detent-quadrant F3. The detentquadrant is provided with a suitable number of perforations to receive the bolt of the latch E4. This construction may be altered for one in which the quadrant is provided with a toothed formation to receive the bolt E4. Then the lever is moved to any desired position, the bolt E4 is sprung into engagement with the quadrant by means of the spring E5 through the connecting-rod E6. NVhen it is desired to change the position of the lever, the handle E7 is grasped, com pressing the spring E5 and raising the bolt lll out of engagement. The leveris then free to be moved to the new position and therein locked.

The intermediate connections consist in the lever F, the forward end of which is pivotal] y connected to the spreader-bar D3 by means of a bolt F. The free end of the lever F is connected to the lower end of the lever E by means of the connecting-rod F2. The lever F is fulcrumed upon the end of the swinging arm F3, which is pivotally mounted upon the land-beam ofthe frame of the plow at F". The lever F is provided with the perforations F5 for an adjustable connection of the free end of the arm F3 therewith. By means of this adjustment the length of the stroke of the forward end of the lever F is increased or diminished as the connection of the arm F3 is moved toward the free end of the lever F or toward the forward end. The forward end of the lever F is also constructed so as to .be adjustable upon the spreader-bar D3, the perforations D5 being provided in the said bar for that purpose.

By means of the intermediate connections here described the carriage carrying the draft-bar A may be shifted from side to side upon the track C3 while under great pressure. By shifting the adjustment of the connection between the end of the arm F3 and the lever F the movement of the carriage may be increased or diminished or the power applied thereto increased or diminished, as desired.

In its operation the land-gage constructed as herein described is connected to the motive power through the draftbar A. This is spread so that a slight movement in either direction will brin g the entire strain upon the length of the draft-chain B, to which it is Connected, and thereby direct the entire Pstrain to that side of the plow to which the draft-bar is shifted. It is by means of this sensitive to the smallest movement.

As before stated, the motive power applied to draw plows of this type is so great that the power applied to shift the land-gage is :necessarily increased. To accomplish this by means of hand-power, the lever F and the swinging arm F3 have been provided. Further, by this construction the line of movement along the straight path of the track C* is maintained withoutpdiminishing the power applied.

Having thus described this invention, what is claimed isl. ln a device of the nature indicated, a frame having a draft-beam, a rod secured to said beam upon the innerside thereof, a draftbar having a wheel provided with a groove receiving the rod, and means for moving the draft-bar and its wheel along said rod; substantially as described.
