CHARLES ANDERSON, OF SOUTH BEND, INDIANA, ASSIGNOR TO THE SOUTH BEND IRON \VORKS, OF SAME PLACE.

PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 247,148, dated September 20, 1881 Application filed July 5, 1881.

' To all whom it may concern.-

Be it known that 1, CHARLES ANDERSON, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Plow-Points and I do hereby declare the following to be a full, clear,'and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings,

which form part of this specification.

My invention relates to an improvement in plow-points, the object being to provide a slipnose attachment for plow-points of such construction that the slip-nose may be reversed when worn, and adapted to be firmly secured to the nose portion of the plow-point. W'ith these objects in view, my invention consists in certain features of construction and combina- 2o tions of parts, as will hereinafter be described, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of the upper side of the slip-nose secured to a plow-point. Fig. 2 is a similar 5 view of the lower side. Fig. 3 is a plan view of the upper side of the forward portion of the plow-point, the slip-nose being removed therefrom. Fig. 4 is a similar view of the under side of the plow-point. Fig. 5 is a view, in per- 0 spective, of the plow-point. Fig. 6 is a plan view of the slip-nose. Fig. 7 isa view, in perspective, of the slip-nose; and Fig. 8 is a transverse section of the slip-nose and plow-point.

A represents a plow point or share, its for- 3 5 ward or nose portion only being shown. The landside edge A of the point is inclined, as illustrated in the drawings, adapting the point for use on that type of plow whichis provided with a slanting landside. The sides of the point-nose are provided with grooves B B, the inside groove, B, extending from the forward end of the projecting portion O rearwardly, and terminating in an elongated recess or socket, 0, formed in the upper face of the point, while the outer groove, B, terminates in an elongated recess or groove, 0 form ed on the under face of the point. The outer side or landside edge, A, is cut away at its forward edge, as at c, and a converging slot, 0, formed therein, while the under side of the point is (No model.)

cut away, as at 0 and a converging slot, 0 formed therein. The sides of each groove B B are beveled, as at d d, and the forward edge of the projection O is also grooved. The grooves B B are identically alike in size and co'nfiguration, the inner groove being located at its rear portion on the upper side of the point, while the rear portion of the outer groove is located on the under face of the point. D represents the slip-nose, the rear portion of which is provided with the lips or projections E E, each of which are provided on their in nor edges with ribs 6, said ribs being connected at their forward ends by the short rib c. The lips or projections E E are identically alike in size and form. The facefof each lip or projection is made throughout its length a continuation of the wearing surface of the nose. The slanting side 9 of each lip is cut away, as at lb, and a tapering projection, j, formed thereon. When the slip-nose is applied to the point the lips or projections E IE will accurately fit the grooves in the point, and this will be the case regardless of the face of the nose, which is placed uppermost.

There are several essential and valuable features in my improved slip nose attachment, which will now be adverted to.

First. The desired shape and contour of the nose portion of share or point is preserved, 8o owing to the fact that the slip-nose is secured in place by side projections seated in grooves on opposite sides of the nose portion of the point, and hence the parts do not require extra thickness to admit of the attachment of the slip-nose.

Second. The slip-noseis made wedge-shaped from its cutting-edge rearwardly, so that when one face becomes unduly worn theslip-nose may be detached and turned over and secured in place with its opposite face uppermost. Thus the slip nose may be used for a great length of time.

Third. The slip-nose, having rearwardly-projecting lips or arms that engage the opposite 5 sides of thenose portion of the share or point, is firmly held against displacement by a single bolt, F, which extends through the nose portion of the share or point and engages in a notch, F, formed in the ribs on theinner edge 1o of the nose lips or projections. The continuous rib on the slip-nose fits in a continuous groove formed in the nose portion of the share or point, and thereby prevents any vertical movement of the slip-nose. Again, the transverse or diagonal strains on the slip-nose are effectually resisted by the lips or rearwarclly-projecting arms on the slip-nose engaging the opposite sides of the nose portion of the point or share. This peculiar method of attachment insures great strength, and forms a strong and durable connection of the parts. Again, the slip-nose is prevented from being twisted out of place, the following provision being made against such an accident: The ribs on the arms or lips of the slip-nose, fitting within grooves formed on opposite edges of the nose portion of the share or point, operate to resist.

such tendency to twist the slip-nose from its seat. Further, the rearwardly-projeeting lips or arms are each locked against both the upper and lower faces of the share or point, and as these lips or arms are located at the side edges of the slip-nose they are adapted to efi'ectually resist alltwisting strains. Again, it will be observed that but a comparatively slight amount of metal is required in the manufacture of a slip-nose constructed in accordance with my invention, and hence they can be supplied at a small initial cost.

While I have illustrated one form of slipnose attachment, I would have it understood that I do not, narrowly, restrict myself to such peculiar form and configuration ofparts, as my invention consists, essentially, in a slip nose having rearwardly projecting lips or arms that fit against the opposite edges of the nose portion of a-plow point or share.

While I have shown myimprovement as attached to a slanting landside or point, it may be constructed for attachment to a share for a straight landside.

I am aware that it is old to construct a slipnose with a singlerearwardly-projecting shank which is secured within an open slot formed in the nose portion ofthe plowshare. In this form of construction the nose portion of the plowshare is weakened, and by the breaking of one of the side walls of the slot the entire plowshare is rendered worthless. Again, I

am aware that it is old to provide a slip-nose with two rearwardly-projecting lips which fit in grooves in the upper and lower sides of the nose portion of the plowshare; but such construction is objectionable, for the reason that the nose portion of the share must be made of undue thickness to allow of grooves in its upper and lower side, it being necessary to make such grooves of considerable depth, in order that the attaching-lips on the slip-nose may be made of snfiicient thickness to withstand the wear. Hence I would have it understood that I make no claim to the forms of construction above referred to.

In my improvement the nose portion of the plow is retained in nearly its proper width, grooves being formed in its side for the insertion of ribs formed on the two arms on the slip-nose, and hence the strength of the nose portion of the plowshare is all-suflicient to withstand the strain to which it is subjected in use.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is 4 1. Areversible slipnose provided with arms or lips extending rearwardly from its opposite edges, substantially as set forth.

2. A reversible slip-nose having its opposite faces arranged in wedge form, and provided with two arms or lips extending rearwardly from its opposite edges, substantially as set forth.

3. The combination, with a share or point having two grooves, one on its landside edge and one on the inner edge of the nose portion of the share or point, of a slip-nose provided with arms orlips which fit within said grooves, substantially as set forth.

4. The combination, with a share or point provided with grooves on opposite sides of its nose portion, of a reversible slip-nose provided with ribbed arms or lips adapted to fit within said grooves, substantially as set forth.

. 5. The combination, with a share or point, of a reversible slip-nose provided-with rearwardly-extending arms or lips that fit in grooves on opposite sides of the noseportion of the point or share, and a single belt for securing the slip-nose against displacement, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand.

CHARLES ANDERSON.
