PLOW.

SPECIFICATION forming part of Letters Patent No. 703,803,dated July 1, 1902.

Application filed April 7,1902. Serial No- ,7 (N0 modem T0 (LZZ whom, it may concern:

Be it known that LJosnrn MICHALKA,a citizen of the United States, and a resident of Cameron, in the county of Milam and State of Texas, have invented a new and Improved Plow, of which the following is a full, clear,

and exact description.

The purpose of the invention is to provide a construction of plow in which the shoe-bar is rigidly secured to the beam and in which the standard may be quickly and conveniently adjusted to any height or depth of cut and likewise adjusted to any inclination found necessary in setting the plowshare or sweep.

Another purpose of the invention is to provide means for adjustablylocking the standard-brace to the standard in such manner that the standard cannot be accidentally moved from position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fullyset forth,and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved plow. Fig. 2 is a plan View of the same. Fig. 3 is a horizontal section taken practically on the line 3 3 of Fig. 1, being drawn upon a larger scale; and Fig. a is a detail perspective view of the standard-brace.

The plow beam A is preferably made of metal and is provided with the usual clevis 10, and the shoe-bar B is rigidly secured to the lower end of the beam, extending a desired distance in front of the lower end of the beam and arequired distance to the rear. The handles A are attached to the shoe-bar B back of the beam by straps 11 or their equivalents, suitable bolts and nuts being employed, and the handles are adjustably connected to the upper rear portion of the beam by horizontal braces 12, having apertures 13, through which bolts 14 are passed into the handle, one pivot-bolt 15 serving to secure both braces to opposite sides of the beam, as is shown in Fig. 2.

The standard 0 consists of two side members 16,downwardly and forwardly curved and spaced and held separated at their bottom portions by a block 17, and between the ends of each member 16 of the standard, at the rear edges of said members, teeth 18 are formed, as is shown in Fig. 1.

In connection with the standard 0 a standard-brace 'D is employed. (Shown in detail in Fig. 4.) This standard-brace consists of a curved body d, the curvature being upward and forward, and a head-section d, which is vertically disposed and extends upward from the body, which head-section consists of a front disk cap 19 and a'vertical rib 20 at the back of the cap adapted to fit into the space betweenthe members 16 of the standard 0, which rib and disk cap are provided with'an aperture 21 to receive a bolt 22, serving to hold the disk cap in engagement with the front edge of the standard members 16, near the top of the standard, asis shown in Figs. 1 and 3. The bolt 22 passes rearward through the space between the standard members 16, and its rear threaded end receives a washer 23,.having a front rib 24, fitting snugly in the space between the standard members 16, the body of the washer having bearing against the rear edge of the washer members, as is illustrated in Fig. 3, and at the extreme rear end of the bolt 22 a nut 25 is located.

The upper portion of the body (1 of the standard-brace D is flattened and is reduced in width to extend diagonally upward between the members 16 of the standard 0 and to produce two vertical side shoulders 26, adapted when the standard-brace is in position to bear against the rear toothed portion of said members, and teeth 27 are formed at the shoulders 26 of the standard-brace D, adapted to enter the spaces between the teeth 18 of the standard, as is illustrated in Fig. 1. The bottom portion 28 of the standard-brace D is bifurcated to receive between its members the forward end of the shoe-bar B, to which it is pivotally attached by a suitable pin or bolt 29.

It will be observed that the standard-brace is locked to the standard in such manner that the connection cannot be shaken loose and that by loosening the bolt 22 the standard can be adjusted to any required height or depth of out and held in adjusted position through the interlocking teeth 18 and 27 when the said bolt 22 is tightened up.

The standard is adjusted to any inclination found necessary in setting the plowshare or sweep, and is connected with the beam below its horizontal portion by means of two strapbraces 30 and 31, which engage with the outer side faces of the standard members 16 at their upper ends, being secured thereto by a suitable bolt and nut 32, and said strap-braces are horizontally and adj ustably connected with the beam A by passing a bolt 33 through any one of a series of apertures 34 in said strap-braces and through the beam, as shown in Fig. 1.

It will be observed that the share or sweep bolt may be passed between the members of the standard 0 and secured to said standard at any point between the upper portion of the standard-brace D and the spacing-block 17.

The construction of plow just described is exceedingly simple and durable and admits of the standard 0 being quickly and positively adjusted vertically or given any inclination it may require. Furthermore, the standardbrace D being pivotally connected with the shoe-bar B and the shoe-bar rigidly attached to the lower end of the beam A render the construction of the plow exceedingly strong and rigid.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1., In a plow, a beam, a shoe-bar secured to the beam, a standard adjustably connected with the beam, an adjusting-brace carried by the shoe-bar and in adjustable engagement with the standard, and means forlocking the brace to the standard, for the purpose described.

2. In a plow, a shoe-bar rigidly secured to the beam, handles carried by the shoe-bar and adjustably connected with the beam, a stand ard located in front of the shoe-bar, a brace carried by the shoe-bar, extending through the standard and having a toothed connection therewith, means for locking the brace to the standard, and auxiliary braces adj ustably connecting the standard with the beam, for the purpose described.

3. In a plow, the combination with abeam and ashoe-bar secured to the beam, of astandard consisting of spaced members connected at their bottom portions by a spacing-block, the members of the standard having teeth formed at their rear edges, a main brace for the standard, pivotally attached to the shoebar and extending diagonally upward between the members of the standard, terminating at its upper end in a ribbed cap-disk arranged for engagement with the forward edges of the standard members, the rib of the cap-disk fitting in the space between the standard members, teeth formed upon the standard-brace at the sides thereof, adapted to mesh with the teeth on the standard members, whereby said standard may be adjusted vertically, and strap-braces adjustably connected with the beam and having connection with the standard, whereby the said standard may be given any desired inclination, as described.

4. In a plow,the combination with the beam and the shoe-bar secured to the beam, of a standard consisting of opposing members separated by a spacing-block located at their lower ends, a brace for the standard, comprising an upwardly and forwardly curved body having'a reduced section which passes diagonally upward between the members of the standard, and a head-section consisting of a cap-plate arranged for engagement with the forward edge of the standard, and a rib at the back of the cap-plate, which fits in the space between the standard members, teeth at the side portions of the standard-brace, adapted for interlocking engagement with the teeth on the standard members, a bolt passed through the cap-plate of the standard-brace and its rib and rearwardly through the space between the standard members, a washer fitted to the rear end of the said bolt, having a rib adapted to fit in the space between the standard members, and a lock-nut for the bolt engaging with the said washer, for the purpose specified.

In testimony whereof I have signed my my name to this specification in the presence of two subscribing witnesses.

JOSEPH MICHALKA.
