REBUILT PLOWSHARE Filed March 23, 1936 ATTORNEY Patented Nov. 3, 1936 UNITED STATES ATET OFFICE 2 Claims.
This invention relates to plowshare rebuilding units and has for the primary object the provision of a device of this character which may be manufactured and sold to the trade at a low cost to permit persons engaged in repairing business to successfully rebuild worn plowshares so that the latter will be restored to new share specifications and capable of providing eflicient service as that of a new share.
With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view illustrating a plowshare repaired by a unit forming the subject matter of the present invention.
Figure 2 is a perspective view showing a worn plowshare and marked to show where said share is cut so as to be adaptable to a repair unit constructed in accordance with the present invention.
Figure 3 is a perspective view illustrating the repair unit.
Figure 4 is a fragmentary perspective view showing a modified form of repair unit.
Figure 5 is a fragmentary plan view showing the repair unit secured to the repaired worn plowshare.
Figure 6 is a fragmentary perspective view illustrating another modified form of my invention.
Referring in detail to the drawing, the numeral I indicates a worn plowshare including a land side 2, a point 3 and a blade 4. The land side is equipped with the usual notches and pins for the application of the share to a plow. A share of the character described after being in use over a period of time becomes worn and to such an extent as to impair its usefulness and also will become detached from the plow by the notches and pins cutting out. Still a worn plowshare of this character contains considerable material which when discarded to be replaced by a complete new share places the user under considerable expense which may be materially reduced by the manufacture and sale to repairmen units 5. These units may be manufactured at a much lower cost than complete new shares and may be readily adaptable to worn shares for restoring the latter to new share specification and service. The securing of a unit to a worn share is preferably by welding so that the repaired share will have the strength and durability of a new share.
The unit 5 consists of a point 6, a land side strip 1 and a blade strip 8 of integral formation 5 forming between the land strip 1, point 6 and blade strip 8 a throat 9. The strip 7 is of a greater thickness than the strip 8. Also the material forming the throat 9 is of considerable thickness so as to provide between the point 6 10 and the strip 1 a rigid construction for aiding in retaining the repair unit in proper shape. The upper edge of the strip 8 adjacent the throat 9 has a slight curve thereto. The construction described relative to the unit will permit the 15 same to be readily adapted to worn shares of different sizes.
To adapt a unit 5 to a worn share the throat and strip 1 are heated so that the repair unit can be expanded or contracted to fit the worn share and it is then placed upon said worn share and the latter marked, as indicated in Figure 2. The worn share is then cut on its markings to remove irregular or worn edges therefrom. The edges of the unit are then brought into abutting engagement with the prepared edges of the worn share and welded thereto. The worn share is then restored to new share specifications with the notches and pins built up or restored so that the repaired 0 share may be adapted to a plow for successful use.
The strip 8 of the repair unit may taper towards its ground edge and be reinforced by tapering ribs H], as shown in Figure 4. This pro- 35 vides a self-sharpening blade and one capable of giving maximum service and durability.
In some instances the plowshare may only have the land side and its point worn. Then a repair unit, as shown in Figure 6, may be adapted 4 thereto. The repair unit shown in Figure 6 only differs from the repair unit 5 in that the blade strip 8 is eliminated.
Having described the invention, I claim:
1. A plowshare rebuilding device comprising 45 a unit including a replacement point, a land side strip and a blade strip, said point and strips being of integral formation and defining therebetween a throat capable of permitting expansion and contraction of the unit for adapting 50 said unit to prepared edges of a worn plowshare with the edges of the unit welded to the edges of the plowshare.
2. A plowshare rebuilding device comprising a unit including a replacement point, a land side 55 strip and a blade strip, said point and strips being of integral formation and defining therebetween a throat capable of permitting expansion and contraction of the unit for adapting said unit to prepared edges of a worn plowshare with the edges of the unit welded to the edges of the plowshare, said blade strip tapering towards a ground edge thereof to render said strip selfsharpening, and tapering ribs formed integrally with one face of the blade strip to provide rigidity thereto.
