Urrsn STATS PATE MANUEL BOUZO, OF HABANA, CUBA,

PLOW.

Application filed May 21, 1923.

This invention relates to improvements in plows.

One of the objects of this invention 1s to improve the structure ot plows, to strengthen the same and enable them to be readily assembled and disassembled.

` Another obj ect of the invention is to provide means between the ground working pieces and the seat bar of the plow to regulate at will the depth at which the share is to operate in the ground.

Another obj-ect of the invention is to provide an improved construction of the share and its supporting means to render them more durable.

The invention is described with reference to the iigures ot the annexed drawing, in which:

Fig. 1 is a side elevation of a moulding r plow provided with the improvements forme ing the subject matter of this invention.

Fig. 2 is a plan of the same.

Fig. 3 is a longitudinal vertical section on line 3-3 of Fig. 2.

Fig. 4 is a perspective detail view of the mould-board.

Fig. 5 is a perspective detail ot the share and its support.

Fig. 6 is a side elevation of a modified form of plow, arranged for use as a trench plow.

Fig. 7 is a plan of said modified form.

Fig. 8 is a partial longitudinal vertical section on line 8 8 of 7.

Fig. 9 is a horizontal section on line 9--9 of Fig. 6.

Figs. 10, 11 and 12 are 'pers}i ecti\'fe views, respectively, oi the share and its support,

f of the mould-board and ot the connecting nece.

l In the drawing, 1 indicates the beam of the plow which is secured by bolts 2 and nuts 2 in the fork at the front end of the seat bar 3 of the plow. Said bar is metallic and ot curved form, having a widened central portion 4 provid-ed with a longitudinal slot 4 for the object hereinafter explained. The seat bar 3 is pivotally connected by a horizontal pin 5 secured in a slot 7 formed in the heel 8 of the plow by a pin 5 and split pin 6. Said heel is curved rearwardly atits upper end and terminates in lateral wings 9 which are also rearwardly and upwardly inclined, and to which are secured the handle bars 11 of the plow by bolts 10.

Serial No. 640,480.

Hand grips 11 are secured to the bars 11, and the latter are connected together by a cross bar 12. Shank of heel 8 is inserted in a slot of bed 13 which is made of forged iron and is integrally connected at'its Jfore end to the share which is made of the same class of material forming the bed 13. Said share is made of flat iron comprising an upper portion 14, al iront upwardly directed abutment 14'* and a side portion downwardly inclined 14 which forms an arcuate angle with the wedge shaped end of the bed 13. The part 14 is designed to receive the lower fore portion ot the mould-board 15 which projects laterally and is integral with a curved upwardly directed bar 16. Mouldboard 15 is fixed to the part 14 by bolts 17 which pass through corresponding holes 18 land 19 in mould-board 15 and part 14 respectively and are secured by nuts 20. The bar 16 has at a distance above the mouldboard 15 a lateral abutment 21 which bears on the upper end of a curved link 22 connecting the bar 16 with the bed 13 and which is secured by pins 23 and 24 and nuts 25 and26. The mould-board is also connected to bed 13 by a brace 27 having ter minal eyes 27', one or' which is iixed to the mould-board 15 by a screw 28 passing through a hole 29 in the mould-board and secured by a corresponding nut. The inner eye 27 of brace 27 is connected to a projection 30 of the seat bar 13 by means oi a pin 31 and nuts 32.

From the upper end loil bar 16 projects a threaded stem 33 which passes loosely through slot 4 of seat bar 4 and is iixed with respect to the same by means of an upper wing nut 34, a washer 35 and a lower wing nut 36.

At the iront end of the beam 1 is arranged a clevis 37 provided with an eye 33 and connected to the sides of the beam b means ot bolts 39. A small plate 40 is iXed von th-e upper tace `of beam 1 by bolts 41 and has a link 42 connected to an eye 41 of said plate 40. A vertical bar 44 is secured to the beam by a clamp 43 and carries the guidingwheel 45.

To regulate the depth at which the point 14" of the share is operated in the ground, nuts 34 and 36 are loosened, the threaded stem 33 is adjusted in the slot 4 of seat bar 3 to the desired position, and the said nuts are then tightened. As the seat bar 3 is ISL:

,minate at its lower end the heel 8 and the vertical knife 48, the latter replacing the bar 16 of the form previously described. Said knife 48 has the threaded stem 33. 1n this form, the share is not provided with the part 14 and the 1nouldboard 15 is independent and has an inverted surface at the rear part with respect to the front part for inverting the ground raised by the share. Share 15 is secured to the mould-board 14l by means of a union plate 48 which has two rows of holes 49 andV 50 and is applied under the adjacent portions of the mouldboard 15 and of. the share 14, and is fixed by rivets 50 which pass through corresponding holes 51 and 52 respectively formed in the mould-board' 15 and the .share 14". The mould-board; 15 is reinforced by braces 53 and 54 similar to brace 27 previously described and by means of which the mould,- board is connected to the bed 13'by means of countersink screws 55 and 56' which pass through side holes 57 and. 58 in the supporting clamps 46 and 47 and through holes formed in the Shanks of the heel' 8 and of the knife 48 and which are secur-edvby the nuts 59 and 60 respectively.

This modified form of plow is adjustable according to the depth it is desired to plow the ground, in theV same manner as previously explained for the moulding plow.

It should be understood that the details of construction of the parts of this plow can be slightly varied without altering the essential character of the invention, which is as pointed out in the appended claims.

What I claim is:

1. A plow comprising a beam having a downwardly-curved standard portion, a bed member, a share integrally formed thereon, a connection member adjustably connected to the beam and rigidly connected to the bed member, handles, and an element to which said' handles are rigidly attached, said element being pivotally connected to said downwardly curved standard portion and rigidly connected to said bed member.

2. A plow comprising a beam having a downwardly-curved standard portion, a bed member having a socket at the middle portion and' another socket at the rear portion, a share integrally formed on the fore portion of the hed member, a connection mem.- ber adj'ustably connected to the beam and rigidly connected to the bed member in the middle socket thereof, handles and an elem-ent to which said handles are rigidly attached, said' element being pivotally connected to saidl downwardly curved standard portion and rigidly connected to the bed member in the rear socket thereof.y

In witness. whereof I' afiix my signature.

MANUEL BOUZO.
