PLOW.

SPECIFICATION forming part of Letters Patent 'No. 694,553, dated March 4, 1902. Applioation filed June29, 1901. Serial No. 66,532. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. KELLY, a citizen of the United States, residing at Longview, in the county of Gregg andState of Texas, have invented a new and useful Plow, of which the following is a specification.

The present invention relates to plows; and the object thereof is to improve the construction of these articles, so that they will be cheaper to manufacture, lighter in weight, and at the same time strong, durable, and rigid.

In a copending application, Serial No. 66,531, filed June 29, 1901, a plow is described having some features similar to certain that are described in this application. These features are covered, broadly, in this other case and only specific claims on a modification are made herein. At the same time there are other novel and important features .in the present case which while primarily intended for use upon shovel-plows may be applied to other kinds Without departing from the spirit of the invention. Among these may be mentioned a block located between the spaced beam-bars and serving not only as a spreader for holding the bars apart, but also constituting means whereby the standard or stock may be adjusted to different inclinations with relation to the beam.

Another feature is a brace that rigidly holds the standard or stock in placeand also forms strengthening means at the point of attachment of the handles to the beam to prevent vibration of the former, thus insuring a rigid and stable structure. These several features are fully described in the following specification and shown in the accompanying drawings; but it will be understood that such changes may be made from the described construction as are within the scope of the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a shovel-plow minus theblade thereof embodying the presentv invention. Fig. 2 is a top plan view of the same. Fig. 3 is a verticallongitudinal section. Fig. 4 is a vertical cross-sectional view taken on the line X X of Fig. 3. Fig. 5 is a detail perspective view of the combined spacing and adjusting block. Figs. 6 and 7 are detail perspective views of the two spacing-blocks employed. Fig. 8 is a side elevation of a portion of a plow, showing a slightly-modified form of brace and its connection with the beam. Fig. 9 is a vertical cross-sectional view through the same.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

In the present embodiment of theinvention a beam 10 is provided, comprising spaced side bars 11, secured at their front ends to the opposite sides of a clevis 12. A pair of spacingblocks 13 are located between the bars intermediate their ends, said blocks having transverse grooves 14, in which are seated tie-bolts 15, that connect the bars 11. These blocks are furthermore provided at their upper ends with outstanding lugs 16, which engage over and bear upon the upper edges of the beambars. A standard 17 is secured to the beam 10 and comprises a shank 18, having a forked head 19, the arms 20 of which embrace and extend transversely across the beam. Fastening-bolts 21 connect the arms 20 above and below the beam.

Interposed between the beam-bars 11 at the point of intersection of the standard is the adjusting-block 22. As clearly shown in Fig. 5 of the drawings, this block is in the form of a hollow boxing having outstanding lips 23 at its upper edge, which lips are arranged to engage over the upper edges of the beam-bar. Its upper face has a plurality of concaved sockets 24E, thus forming transverse shoulders 25. Said shoulders will thus be located above the upper edge of the beam when the box is in place between the bars thereof, and the upper fastening-bolt 21 of the standards is arranged to engage in' one of the sockets. By this means the standards are adjustably secured to the plow in a manner readily understood.

The ends of the rearwardly-extending portions of the beam-bars are provided with up wardly-extending offset arms 26, that are arranged in divergin g relation,and to these arms are bolted or otherwise secured the haudles27. In practice these arms are arranged in such a relation to the beam that the handles when secured thereto will be located at the proper inclination. In order to hold the standard in rigid relation to the beam, the brace 28 is employed, such brace being secured at its lower end to the shank 18 of the standard and having its upper end fastened to the rearwardly-extending portions of the beam contiguous to the connections of the handles therewith. The preferred manner of accomplishing this is as shown in Figs. 1 to 3 of the drawings,wherein the upper end of the brace has a cross-head 29, that is located between the beam-bars and is secured by means of a transverse bolt 30. Another mode, however, is shown in Figs. 8 and 9. In this instance a block 31 is located between the bars 11, and the brace has a horizontal eye 32, that fits against the under side of the same. A vertically-disposed bolt 33 passes through this eye and the block 31, and thus rigidly connects the brace to the beam. The standard is pivotally connected to the brace, so that when it is desired to change the inclination of said standard it is only necessary to adjust the upper end of the same upon the block.

It will be seen that several important advantages are derived from this construction. In the first place a much lighter structure is provided than is possible with a solid beam. At the same time the parts are rigidly braced, and said parts are reduced to the smallest number, for the reason that many of them perform several functions.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to withoutdeparting from the spirit or sacrificing anyof the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a plow, the combination with a beam comprising spaced bars, of a standard secured to the beam intermediate the ends thereof, a brace fastened at its front end to the standard and having its rear end secured to the beam-bars contiguous to their rear ends, the terminals of said bars in rear of the brace being upturned, and handles attached to said upturned ends.

2. In a plow, the combination with a beam comprising spaced bars having upturned portions at their rear ends, of a standard secu red to an intermediate part of the beam in front of the upturned portion and comprising spaced arms which embrace said beam, a rearwardly-extending brace secured at its lower end between the arms of the standard and at its upper end contiguous to their upturned portions and in rearof the standards, and handles secured to said upturned portions.

3. In a plow, the beam comprising spaced bars, in combination with a block located between the bars and constituting a spacingblock therefor, and a standard having its upper end embracing the bars an '1 engaged with one face of the block.

4. In a plow, the combination with a beam comprising spaced bars, of an adjusting-block located between the bars, and a standard having an adjustable engagement with the block and movable longitudinally of the beam.

10. In a plow, the combination with a beam comprising spaced bars, of a standard attached to the beam and having its upper end embracing the spaced bars, said standard engaging the upper and lower edges of the bars, and a brace secured to the standard at one end and having its other end fastened between the bars and constituting a spacing device for said bars.

11. In a plow, the combination with a beam comprising spaced bars, of a brace secured to the bars, a standard pivotally attached to the brace and having its upper end embracing and adjustable upon the beam-bars, and a block secured between the beam-bars, said standard having an adjustable connection with the block.
