' Appamitnna september19;1996,;.sanrnaaasgsoa controlled, one `whereby the plow will be guided in its advance movement, and'one which insures the formation of straight even `to form 'a standard 2, to which is connected' -furrows A further object ofthe invention is `to pro- -vide adevice of this character whereinthe handle-bars may be readily adjusted.tol aecord with the height of the operator,"one iny which the bars will be securelylocked in ad;v

justed positions, and one wherein the-rattle4 may be conveniently adjusted. toy accord with the adjustments of thehandles.

With these and other objects in view the invention comprises the'no'vel features-fof construction and combination of parts-more fullyr hereinafter described.

In the accompanying dra gs, Figure-luis aside elevation of a plow equippedwith an attachment embodyin the invention. fFig.

2 is atop plan view .of t e same', l

Referring to the drawings, 1 designates the plow-beam, bent, as usual, 'at its rear'end the plow-blade 3, (shown by dotted lines in' Fig'. 1,) these parts, which areof ordinary form and material, being designed in prac-lv tice to perform their ordinary functions.

Fixed .to the lower end of the-standard`2 by means. of a fastening member or bolt 4 is a shoe comprisingr .a pair of relativel spaced horizontal plates 5, between whic there lis pivoted atl its forward end, by means of a transverse pivoting member or bolt 6, a runner 7, having at its rear end an uprising portion or arm`8, adapted for vertical movement with the runner-blade between the plates 5, the rear ends of which are connected by means of a transverse clamping member or bolt 9, disposed inlinediately in rear of the arm 8.

Secured-to the upper portion of the stand- .with hand-grips 21`andat their lower ends fwith transverse heads 22, rovided withslots the grip portion 21` thereof. i

ment of the pawl 26 with therao Yard-2 b\ymeans .ofclipliolts 10 is a pair off 5'5- 'bearing-heads '11' 1 2, of which the latter has i a' rearwardly-hiclined 'portion provided with`- a longitudinal guide opening or slot 13, thereA -being pivoted to the ,bearing member 11 one end of-'an arcuate rack 14, provided with teeth 15, and having its other end adjustablyl connected with the bearing member 12 by means ofa bolt 16,l which works the slot`13, whereby the lower end of the rack mybe adjusted toward and from the standar Attached at their lower ends to the forward end of the shoe -5 is a pair of upwardly and rearwardlyinclined arms 17 mamtained in frictional engagement with the standard 2 by means of a'transverseclamping-bolt 18, there being'pivoted between their ends, as at 19,:to thejup'per ends ofthe arms 17 a pair of handle-bars 20, provided at their upper ends 23,. designed toreceive astening-bolts 24,

, through `the medium of which the lower ends of the bars arel attached to the arms 17, while Y slidably engaged with' a. bearingbracket I25, attached to the inner facezof one of the arms,

.'is'a pawl 26,`acted upon by a spring 27 for I maintaining its forward vend in engagement with-thefrack-teeth 15Y and having its rear end lconnected by a rod 28 with the lever 29, pivoted to one ofthe handle-bars adjacent In practice as the plow advances through. the ground .the runner- 7 will become lembedded inthe lsoil and serve for properly guiding the plow in'its movements, thus to prevent" lateral movement ofthe plow and form straight even furrows, it being apparent that the runner-blade maybe adjusted vertically for varying its depth of entrance into the soil and be fixed in its adjusted positions through the medium ofthe bolt 9.

In the use of the plow the rearendsof the handleba'rs 20 may by manipulating the lever 29 to free the pawl from the teeth 15 be plane 'to accord with the height of the operator, the movements of the bars being limited through the slota1idbolt connection 23 24, it being understood that after the proper ad 'ustfment/has been attained the'bars may be ed against further movement ythrough @Muff swung upward or downward in `a' vertical l engagether, that the lower end of the rack may be moved toward and from the standard to accord with the inclination of the handle-bars, Wheeby the pawl may properly engage the -teet Having thus described my invention, what I claim is.

1. In a device of the class described, a plow-standard, a pair of u Wardly and rear- Wardly inclined arms fixed yconnected therewith, a segmental rack attached to the standard at a point between the arms, handle-bars.'

pivoted between their ends respectively to said arms and provided at their forward ends with transversely-extended slotted heads, fastening members. entered through the slotted heads and engaged with the arms for movably connecting the forward ends of the handle-bars tol the latter, the rear endsof the bars being adjustable in a vertical plane, a locking-pawl movably mounted on one of the handle-bars for engagement, with the rack to fix the bars in adjusted position,

and means for operating the pawl.

2. In a devicev of the class described, a plow-standard, a pair'ef rearwardly and up- Wardly inclined arms xedlyconnected therei for adjustment toward andv from the standard, a pair of handle-bars pivoted between y their ends respectively to the arms and having their forward ends adjustably engaged vwith, a pair of bearing-heads attached to the by slot-and-bolt connections with the arms to permit vertical adjustment of the rear' ends of the bars, a movable locking member carried by `one of the bars for engagement with the rack to x the bars in adjusted positions; and means for operating the locking member. g

In testimony whereof; I aX my signature in presence of two Witnesses.
