WILLIAM H. LEE, OF SYRACUSE, NEW YORK, ASSIGNOR TO SYItAC'lJ'SE CHILLED PLOW COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.
PLOW CONSTRUCTION (DETACHABLE SHARE.)
Specification of Letters Patent. Patented Jan 13, 1920- Application filed March 23, 1918. Serial No. 224,252.
To all whom it may concern:
Be it known that I, VVILLIAM H. LEE, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Plow Construction (Detachable Share,) of which the following is a specification.
This invention relates to plows and has for its object a particularly simple and efficient construction of plow or plow bottom by which the share is detachably mounted on the frog and held snugly in position and is readily removable and replaceable; and the invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. 7
In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.
Figure 1 is an elevation from the furrow side of the plow, the share being shown as displaced forwardly.
Fig. 2 is an enlarged inverted view of the plow, the mold board being broken away.
Fig. 8 is an elevation of the share taken from the land side thereof.
Fig. 4 is an elevation of the frog taken from the land side thereof.
Fig. 5 is a sectional view taken on the plane of line 55, Fig. 1 showing in elevation the inner face of the gunnel or land side of the share.
Fig. 6 is an enlarged sectional View taken on line 66, Fig. 2.
Fig. 7 is an enlarged fragmentary sectional view illustrating the nut on the share forming part of the means for securing the share to the frog.
This plow or plow bottom comprises a suitable support or frog 1, a mold board 2, and a share 3 movable edgewisely into and out of engagement with the frog, the share and the frog having wedging means which come into interlocking engagement when the share is in position on the frog, the wedging means having inclined plane surfaces which engage substantially throughout their entire extent and also wedge or draw the share in position on the frog. Said interlocking means is arranged to come into engagement upon a rearward edgewise movement or a lateral edgewise movement of the share or a combination of the two movements relatively to the frog.
The frog may be ofany suitable form, size and construction, it being usually formed of malleable iron and havin a major part or body located toward the f urrow side of the plow and an angular flange 4 toward the land side of the plow, the angle formed by the body of the frog and the flange 4 being located just behind the cutting'edge or shin of the mold board and the cutting edge of the share, as will be understood by those skilled in the art. The mold board may be of any suitable form, size and construction and is secured to the frog in any suitable manner, it being here shown as includinga' shin piece 5 which is separable fronrthe main body of the mold board.
The share 3 is formed with a substantially upright landslide flange 6, this flange being sometimes called a gunnel. The flange 6 laps the flange 4 ofthe frog while the major part of the share laps the body or upper faceof the frog. v
The means on the frog and share for in"- terlocking, as here shown, comprises an undercut inclined or bevel face 7 extending in a general direction lengthwise of the angular side or flange 4 of the frog and parallel to the upperface of the frog, and a complemental upwardly facing inclined planesurface provided on the inner side of the gunnel or flange 6 of the share. As here" illustrated, the undercut bevel face 7 is the upper wall of a groove 9 formed in'the angular flange 4 and opening at its advance end through the front edge of said flange 4; and
the inclined surface 8 is the upper wall or face of a rib 10 provided on the gunnel flange 6.
The groove 9 in the flange 4 extends in a general direction parallel tothe upperface of the frog,'and the rib 10 is provided on the inner face of its flange or gunnel 6. The incline of the inclined plane surfaces 7, 8, is inwardly and downwardly, that is, toward the furrow side of the plow and away from the uppersurface of the frog The groove 9 is open at its front end, and hence the share can be moved rearwardly from its position shown in Fig. 1 and the rib 10' slid.- endwisely" in the groove- 9 or the parts can be brought into interlocking engagement by a lateral movement of the share from the land side of the plow.
By reason of the inclined plane surfaces 7 and 8 of the groove 9 and rib '10, a wide bearing surface is provided on the frog, which bearing surface is not mutilated or destroyed by the ribs of different shares, it being understood that the shares are replaced when worn. By reason of the engagement of the comparatively wide inclined plane faces 7, 8 said faces are not modified by successive changes of shares and are always in the same condition when the share is removed as when first attached.
In some forms of plows the frog and share are of metal of approximately the same hardness and the frog is provided with an ordinary slot while the share is formed with what is termed a staple which enters the slot but does not fit the same, the staple bearing at its base only on a small margin of the walls of the slot at the entrance thereof. If such construction were used with the malleable iron frog, the wall of the groove or slot, owing to the small bearing surface of the staple, would be soon mutilated and the form thereof changed so that when the new share was attached, the rib would not find a snug bearing in the slot or groove.
By reason of the inclined bearing faces of this construction, the groove in the malleable iron frog will maintain its shape.
. The share 3 and mold board 2 are provided with interlocking means at their meeting edges, this means consisting of a tongue 11 projecting from the rear edge of the share and entering into a recess 12 in the under side of the front edge of the mold board, the tongue 11 and recess 12 being located near the lower edges of the mold board and the share.
The share is additionally attached in posi tion by means of a draw bolt 13 connected to the share and extending through an eye orlug 15 on the rear side of the frog and a nut 16 screwed on the bolt against the rear side of the lug.
The draw bolt 13 as here shown is provlded with an eye 17 at its head end and is connected to the share by a latch plate or link- 18 linked at one end into the eye 17 and detachably coupled at its other end to theshare.
As here illustrated, the plate 18 is formed wlth an elongated or non-circular slot 19; a screw bolt 20' extends through the share and the slot 19; and a nut or button 21 turns on the screw bolt against the share. The nut 21 1s preferably of the same shape as the slot and is provided with overhanging shoulders 22 at its ends and the margin of the wall at the outer end of the slot 19 hooks over the shoulder 22 at the advance end of the nut by an endwise movement of the link or latch 18. The screw bolt is formed with a squared portion 23 adjacent its head which fits a complemental portion of the opening in the share. Hence, the screw bolt is held from turning. The nut 21 is also formed with a counter bore for receiving the squared portion of the screw bolt in case such squared portion should project beyond the rear face of the square.
In operation, the nut 21 is turned on the screw 20 against the lower face of the share. When the share is to be removed the nut 16 on the draw bolt 18 is loosened to permit the draw bolt and link 18 to have enough endwise movement forwardly to unhook the link or latch 18 from the shoulder 22 of the nut 21 so that the iatch can be slipped over the nut 21 or unlatched or unbuttoned. The share is attached by a reversal of the movements of these parts.
In either attaching or detaching the share it is not necessary to remove the nut 16 or remove the draw bolt 13. Should the nut 20 when first tightened not stand parallel to the slot 19, the screw bolt can be withdrawn and given a quarter turn and replaced in its square opening, a quarter turn being sufficient to arrange the threads of the screw bolt so that the nut 20 will stand when tightened in effective position.
What I claim is:
1. In a plow, a frog having a lengthwise undercut beveled surface on the angular side thereof toward the land side of the plow, said surface extending forwardly and rearwardly in a general direction parallel to the face of thefrog, and a share detachablY.
mounted on the upper face of the frog and having a gunnel flange arranged to lap said angular side of the frog, the gunnel flange havin a ro'ectino; u wardl facin inclined plane surface complemental to said bevel surface and arranged to engage the same and draw the share onto the face of the frog when the frog and share are assembled, substantially as and for the purpose set forth.
2. In a plow, a frog, a mold board mounted on the frog, and a share detachably mounted on the upper face of the frog and movable edgewisely into engagement therewith, the frog being formed with an undercut beveled surface extending forwardly and rearwardly in a general direction parallel to the face of the frog, and the share having a lengthwisely extending complemental upwardly facing inclined surface armg interlocking means at their meeting edges, substantially as and for the purpose specified.
3. In a. plow, a frog, and a share detachably mounted on the upper face of the frog, the frog being formed with a lengthwise groove in the angular side thereof toward the land side of the plow, the groove extending in a general direction parallel to the upper face of the frog, and being open at its front end, the share having a gunnel flange provided with a rib on the inner face thereof arranged to enter the groove upon edgewise movement of the share relatively to the frog, the upper side of the groove toward the upper face of the frog being inclined downwardly and inwardly away from said face and the rib having its upper face similarly inclined, substantially as and for the purpose specified.
&. In a plow, a frog, and a share detachably mounted on the frog and movable edgewisely into and out of engagement with the 20 frog in a lateral direction and a rearward direction, the angular side of the frog on the land side flange thereof being formed with a groove extending in a direction crosswise of the frog parallel to its upper face, the
groove being open at its front end and the share being provided with the rib for entering the'groove in a lateral direction upon lateral movement of the share and in an endwise direction upon rearward movement of the share, the groove and the rib having inclined plane surfaces on the upper walls thereof arranged to engage and draw the share onto thevface of the frog, substantially as and for the purpose set forth.
In testimony whereof I have hereunto signed my name, at Syracuse, in the county of Onondaga and State of New York, this 22nd day of February, 1918.
