JAMES ALLEN HUGGINS, 015 BED SPRINGS, NORTH CAROLINA.

PLOW.

To all whom it may concern:

Be it known that I, JAMES ALLEN HUG- ems, a citizen of the United States, residing at Red Springs, in the county of Robeson and State of North Carolina, have invented certain new and useful Improvements in Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in plows.

One object of the invention is to provide a plow having a pivoted standard adapted to be adjusted to regulate the. position of the blade or shovel of the plow and having a runner bar adapted to be automatically adjusted by the movement of the beam to correspond with the adjusted position of the blade or shovel.

Another object is to provide a runner adapted to the purpose for which it is designed.

\Vith these and other objects in view the invention consists of certain novel features of construction combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l is a side view of a portion of a plow embodying the invention, parts being broken away; Fig. 2 is a similar view showing the parts adjusted to another position; Fig. 3 is a cross sectional view on the line 3-45 of Fig. 1; Fig. 4 is a horizontal sectional view on the line H of Fig. 1; Fig. 5 is a view similar to Fig. 1 showing a modified form of the invention; Fig. 6 is a similar view showing the parts adjusted to another position; Fig. 7 is a cross sectional view on the line 77 of Fig. 5. Fig. 8 is a side view partly in section showing the application of the invention to a wooden beam plow.

Referring more particularly to Figs. 1, 2 and 3 of the drawings, 1 denotes the plow beam which is provided near its rear end with a longitudinal slot 1. The beam 1 has a segmental downwardly curved rear portion 2 to the lower end of which is pivotally connected the rear ends of a pair of runner supporting and standard attaching bars 3.

Serial No. 635,561.

To the forward ends of the bars 3 is connected the lower end of the adjustable standard 1 of the plow. The lower portion of the standard 4 is bifurcated and the upper portionprojects through the slot in the beam 1 and forms a lever 5 whereby the standard is swung backward'and forward on its pivotal connection with the bars 3 thereby tilting the plow blade or shovel 6 to the desired angle. The upper or lever portion 5 of the standard is provided with a spring projected pawl 7 adapted to work through the slot 1 and to be engaged with a segmental rack bar 8 secured to and spaced a suitable distance below the beam as shown. In the standard and adapted to slidably en gage the space between the rack bar 8 and the lower edge of the beam is a guide pin 9. Pivotally connected to the bars 3 are pairs of runner adjusting levers 10 and 11. The lower ends of the levers 10 and 11 are curved and have formed therein curved slots 12 as shown. To the curved lower ends of the levers 10 and 11 is connected a runner 13 having a central upwardly extending web l3 which is disposed between the lower ends of the levers 10 and 11 and has arranged therein transversely disposed pins 14 which are engaged with the slots 12 whereby when the levers are rocked in the pro-per direction the runner will be raised and lowere The pairs of levers 10 and 11 are connected together to operate in unison by a link or connecting bar 15. The levers 10 are considerably longer than the levers 11 and said levers 10 are connected at their upper ends to the standard 1 by a link 16 whereby when the standard is swung forwardly or rearwardly to adjust the blade or shovel of the plow the levers 10 and 11 will be simultaneously rocked through the links 15 and 16 thus raising and lowering the runner 18 whereby the relative position thereof with respect to the blade or shovel is maintained. l/Vhen thus operated the runner will be raised and lowered straight or directly up and down.

In Figs. 5, 6 and 7 of the drawings is shown a slightly modified form of the invention. In this form of the invention the beam are pivotally connected the rear ends of a pair of forwardly extending parallel runner supporting and standard. attaching bars 18 to the forward ends of which is pivotally connected the bifurcated lower portion of a standard 19 on the lower end of which is secured the blade or shovel 20 of the plow. The upper end of the standard projects above the beam and forms a lever 21 whereby the standard is operated. The upper or lever portion 21 of the standard is provided with a spring projected pawl 22 which is adapted to engage a segmental rack 23 secured to the upper edge of the downwardly curved rear end of the beam as shown. By means of the pawl. 22 and rack 23 the lever and standard of the plow are secured in their adjusted positions. Arranged through the standard 19 adjacent to the lower edge of the beam is a transversely disposed guide pin 21 which assists in guiding and holding the standard in position. Pivotally connected to the bars 18 and arranged between the same are pairs of land side attaching bars 25 and 26 to the lower ends of which is pivotally connected a runner 27 having a central upwardly extending 'web 28 in the upper edge of which are formed notches 29 the purpose of which will be hereinafter described. The levers 25 are of considerably greater length than the levers 26 and said levers 25 are pivotally connected at their upper ends to the standards 19 by a link 30. The levers 25 are connected at their upper ends to the levers 26 by a link 31 whereby said levers are caused to operate in unison when actuated by the standard. By thus connecting the runner 27 to the levers 25 and 26, said runner will be lifted by a forward circular movement when the standard is rocked to adjust the blades of the plow thus simultaneously and automatically adjusting the runner whereby the latter is caused to maintain the same relative position with respect to the plow blade or shovel. When the runneris lifted in the manner described the notches in the web 28 thereof engage the pivot bolts by which the pairs of levers and 26 are connected. to the attaching bars 18.

In Fig. 8 of the drawings the invention is shown as being applied to a plow having a wooden beam 32 to the rear end of which are connected the upper ends of substan tially right angular standard attaching bars 33 said upper ends of the bars being provided with series of bolt holes 3&- adapted to receive a fastening bolt 35 whereby the end of the beam may be adjustably connected to the attaching bars. To the forward ends of the lower portion of the attaching bars 33 is pivotally connected the lower end of a bifurcated standard 86 the upper end of which projects through a slot 37 formed in the beam 32 and has connected thereto an ard adjacent to the lower edge of said rack bar is arranged a guide pin l2. Pivotally connected to the lower horizontal portions of the attaching bars 33 are pairs of runner supporting levers 4:3 and. ist to the lower ends of which is pivotally connected a runner L5. The levers 43 are connected at their upper ends to the standard 36 by a link 46 and said pairs of levers 43 and a l are con nected together by a link 47 whereby said levers are moved in unison by the standard 36 and lever 38 thus raising and lowering the runner 4:5 to cause the same to maintain the same relative position with respect to the shovel or blade 39 of the plow when the latter is tilted. The runner 45 is constructed in the same manner as those described in the previous forms of the invention and in its web are formed notches 1 .8 which engage the pivot pins of the pairs of lovers 48 and a l when said runner is raised by said lever. By constructing and arranging the curved rack bar 41 as herein shown and described said bar also forms a brace for the beam of the plow, said beam being pivotally connected to the upper end of the bar to permit the rear end of the beam to be adjustably connected to the upper ends of the attaching bars 83 as hereinbefore described.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood witlr out requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention claimed.
