PLOW-SHOE.
SPECIFICATION forming part of Letters Patent No. 788,961, dated May 2, 1905.
Application filed July 21, 1904. Serial No. 217,477.
slide attached usually adjustably to the plow-' standard so as to run on the ground or in the furrow behind the plow to guide it or regulate its inclination and depth of penetration according to the set and relative elevation of the shoe.
My invention is an improved device of this character applicable to any kind of plow and having the following main advantages: simplicity of construction and effective operation; greater facility and amplitude of adjustment; confinement of wear to the shoe proper or bar, which may be renewed when desired at a low cost without necessity of replacing other parts; light draft and easy running; strength, durability, and capability to yield under strains and avoid breakage to which the ordinary cast or rigidly-attached shoes are liable.
In the accompanying drawings, which form a part of this specification, I have illustrated a practical embodiment of the invention, which will be fully described by reference to said drawings and then defined in the annexed claims.
Figure 1 is a front perspective view of an ordinary shovel-plow having my improved shoe or runner attached thereto. Fig. 2' is a side view of the same. Fig. 3 is a detail view of the block which is clamped to the plowstandard.
As before stated, the attachment is applica- A plow-stock of ordinary construction is illustrated comprising a plow-beam 1, standard 2, and inclined brace 3, rigidly connecting the standard and beam.
- An ordinary shovel-plow A is shown attached to the foot of the standard.
The shoe or runner 5, of suitable length and weight, is attached to the standard behind the plow, so as to run horizontally on the soil or in the furrow, and has preferably an upturned and tapered or pointed front end to avoid dragging earth ahead of it. The shoe is attached to the standard by means of a stout U- shaped spring 6 and suitable fastenings securing it to the standard and the shoe. spring is preferably arc-shaped or substantially semicircular. It is shown formed of a doubled piece of stout steel spring-rod bent or curved into proper shape. The lower part of the spring is secured in a concave or curved seat therefor at the front of the shoe or runner, the two round arms of the spring resting in grooves therefor in said seat and being clamped thereto by a cross-piece or spanner 7 and bolt 8. The upper part of the spring is secured between two clamp-blocks 9 10, having confronting curved surfaces to accommodate the spring and grooves therein as seats for the two arms of the springs. The clampblocks with the spring thus embraced between them are secured to the standard by a bolt 11, inserted through the standard and through the blocks 9 l0 and having a fastening-nut 12 thereon. This nut is shown provided with a curled projection 13 to receive a rod for turn ing the nut should a suitable wrench be unhandy. The block 9 is shown having a front rib to fit between the two members of the standard, and it is thicker at one end than at the other. It may be used with the thicker end either uppermost or lowermost, which makes quite a difierence in the set of the shoe.
By virtue of the construction and arrange- This ment described the shoe is capable of ready adjustment at any desired set or position; Adjustments may be obtained by loosening the nut 12 and slipping the spring around either up or down between the clamp-blocks 9 10 or by loosening the clamp-piece '7 of the shoe and moving the latter relatively to the spring. At whatever inclination the plow is set the shoe can be set to run horizontally. Relative elevation of the shoe can be varied by adjusting the position of the spring in both the clamps 9 10 and the shoe-clamp piece 7, as well as by moving up or down the bolt 11 in the standard.
It will be observed that only the shoe or runner proper is subject to wear, and this may be detached and replaced by a new one at a low cost when desired.
The shoe is easy running and does not cause heavy drag. The spring allows it to yield slightly, rendering it much less liable to breakage than the ordinary shoes attached rigidly or by cast fastenings. Should the plow be dropped on hard ground, the greatest strain would come on the middle part of the spring, which is nearly vertical and is the strongest point, so that there is but little danger of breaking.
I claim as my invention and desire to secure by Letters Patent of the United States- 1. An attachment for plows comprising a shoe or runner in the form of an elongated bar having a U-shaped spring secured to its forward part and adapted for attachment to the plow-standard as the means of connection between the standard and the shoe.
2. A plow attachment comprising, in combination with the standard, a shoe or runner behind the same, and a U-shaped connecting member adjustably secured to said standard and to said shoe.
. 3. A plow attachment comprising, in combination with the standard, a shoe or runner behind the same, and an arc-shaped or semicircular spring adjustably secured to said standard and to said shoe.
4. A plow attachment comprising, in combination with the standard, a shoe or runner behind the same, and an arc-shaped or semicircular spring adjustably secured to said standard and to said shoe, said spring consisting of a doubled piece of spring-rod, clampblocks having curved and grooved faces to embrace the spring and bolted to said standard, and a spanner or cross-piece engaging the lower ends of said spring and clamped to said shoe.
5. A plow attachment comprising, in combination with the standard, a shoe or runner behind the same, and a U-shaped connecting member adjustably secured to said standard and to said shoe, the connection to the standard including an interposed clamp-block having one end thicker than the other.
6. A plow attachment comprising, in combination with a standard, a shoe or runner behind the same, and an arc-shaped or particircular spring connecting said shoe and standard and adjustably secured to at least one of these parts.
7 A plow attachment comprising, in combination with a standard, a shoe or runner behind the same, and a particircular spring connecting said shoe and standard and adjustably secured to said shoe.
8. A plow attachment comprising a shoe or runner adjustably spring-held from the back of the plow-standard.
9. A plow attachment comprising, in combination with the standard, a shoe or runner, and a curved connecting member between said standard and shoe adjustably secured to one of said parts to permit adjustment of the shoe relatively to the plow.
10. A plow attachment comprising a shoe or runner in the form of a bar adapted to run behind the plow, having an arc-shaped seat in its forward portion arranged longitudinally of the bar, and a substantially semicircular spring adjustably secured in said seat and having its upstanding portion adapted for attachment to the plow-standard.
11. A plow attachment comprising a shoe or runner in the form of a bar adapted to run behind the plow, having an arc-shaped seat in its forward portion arranged longitudinally of the bar, and a substantially semicircular spring adjustably secured in said seat and having its upstanding portion adapted for attachment to the plow-standard, and curved clamp-blocks embracing said spring and adapted to be bolted to the plow-standard for attaching said spring thereto.
In testimony whereof I aflix my signature in presence of two witnesses.
WILLIAM J. STOGNER.
