Patented Sept. 30, 1952 UNITED STATES PATENT OFFICE SNOWPLOW SHOE Ward W. Weller, Auburndale, Mass. Application January 28, 1950, Serial No. 141,088
Claims. 1
The present invention relates to new and useful improvements in snow plow's, and more particularly to snow plow shoe assemblies for use in supporting the blades or mold boards therefor.
Among the objects of the present invention is to provide a novel snow plow shoe assembly adapted to be readily connected to the snow plow frame and which is provided with a wear plate easily replaceable from time to time as occasion demands.
The presentl invention is characterized by the provision of a snow plow shoe assembly comprising a shoe and a plate which may be readily connected to or removed from the shoe and which shoe and plate have an interlocking wedging connection for holding the wear plate in assembled relation with the shoe.
Still another object of the present invention is to provide a snow plow shoe assembly having a readily replaceable wear plate assembled in wedging relation to the shoe or support therefor and having the further provision of cooperatively interengaging with the shoe to prevent undesirable displacement or movement of the wear plate with respect to the shoe or support.
The present invention further contemplates a snow plow shoe assembly which is simple in construction, strong, durable, and reliable in use,
and which may be manufactured at a relatively low cost.
Other objects, features, capabilities and advantages are comprehended by the invention, as will later appear and as are inherently possessed thereby.
Referring to the drawings:
Figure 1 is a view in side elevation of a snow vplow shoe assembly made in accordance with the present invention and showing in dotted lines the manner of attachment to the framer of a snow plow;
Figure 2 is a top plan view of the snow plow shoe assembly shown in Figure 1 of the drawings;
Figure 3 is an enlarged transverse cross-sectional view through the'snow plow shoe assembly shown in Figures 1 and 2; and
Figure 4 is an enlarged fragmentary View in cross section of the snow plow shoe assembly, disclosing more in particular the connecting or interlocking means for holding the plate and shoe in assembled relation.
Referring now more in detail to the drawings, the snow plow shoe assembly embodying the novel features of the present invention is shown in Figures 1 and 2 as comprising a shoe or support 2 and a removable wear plate 4. The shoe 2 is formed with a central base portion 6 and theoutwardly and upwardly extending arm portions 8 and l0, reinforced by the upstanding spaced ribs 9 and Il. The arm portions 8 2 and l0 are provided with the openings l2 and I4, respectively, for connecting the shoe to the frame structure I6 for the snow plow, as by means of the bolts disclosed in the drawings. it being understood, however, that the invention contemplates any other form of attachment means such, for example, as a connection involving the welding of the shoe to the snow plow frame or support.
The snow plow frame structure I6 may be of the conventional type used for supporting one or more blades or mold boards constituting the working part or parts of the plow which are suitably mounted in front of, and operated by, any suitable prime mover, such as a motor vehicle or tractor for clearing rights of way such as roads, tracks, sidewalks, and the like. The shoe assembly herein disclosed is adapted to contact the ground or other supporting medium for the plow and its prime mover, and because of its sliding engagement with the said ground or other supporting medium, is subjected to considerable wear in the normal use of the vehicle and the snow plow attached thereto. Because of such wear, it has been found desirable to embody in the assembly herein disclosed a quickly detachable and replaceable wear plate which may be formed of wear resistant metal adapted for service over long periods of time, and to provide a connection or interlocking fitting between the wearplate and the shoe or supporting means for rigidly holding the plate and shoe in assembled relation, and to prevent longitudinal displacement between the two. The present invention contemplates a connection involving an interlocking wedging relation between the wear plate and the shoe to hold the same in assembled relation and to prevent any appreciable movement between the shoe and plate which would cause excessive Wear, whereby the shoe may be used over long periods ottime before replacement becomes necessary.
The embodiment shown herein to illustrate the invention contemplates vproviding a plurality of openings or apertures I8 extending through the base portion 6 of the shoe, each of which is provided with tapered walls adapted to receive v`a lug 20 extending upwardly from the upper planar surface 22 located centrally of the wear plate 4. The lugs 20 are of tapered construction adapted to Wedgingly engage or interlock with the tapered walls of the apertures I8 whereby the wear plate 4 may be drawn into tight engagement with the planar surface 22 in contact with the planar surface 24 forming the central andlower face'lof the shoe 2. Each of the lugs `2l) is formed with a transverse opening 26 extending above the top surface of the base portion 6 adapted to receive a Cotter pin 28 which extends therethrough in engaging relation with the top ing formed with an upwardly curved portion at its base for deecting the split end of the cotter pin upwardly when the same is inserted into its interlocking position with the lugzan'd baseportion.
The shoe 2 is further formed with planar surfaces 32 and 34 extending angularly and vupwardly from the bottomfface 24 of the base por- ,tion f6 andwhich .-,terminatein the depending ,shoulders r`36 ,and ....3B, respectively, Aextending .transversely of .the shoe 1on .the under side lof .-arm .portio ns r,il .and L0. The wear platev 4 is ,formedwith upwardly extending end marginal portions. 4 0 and 42 having ,the ,angularlynd 11D- vwardly extending planar surfaces 44 and 46, re- ,spectively engaging the surfaces 3 2 and 34 of the shoe.` The upwardly extendingendmarginal portions of .the wear platedovevtail into .the shoein .abutting Arelation withy thev Shoulders ,3,5 dhd38, respectively, whereby the wear. plate and .shoe Jare .interlocked in wedgin'g relation at the ends of the wear plateto,preventrelativelongitudinaldisplacement of the wearplateand shoe duringoperationofthe device. l l
.Fromthe above, disclosurait will be 'apparent .that the assembly is ,characterized by. the .provision. of .a wear plate whichmay be rcadilyreplacedas occasiondemands. Because of the novel structure incorporated, in .the assembly, the replacement of .a wear ,plate which has ,become .worn to `such,anextentas to make it ineffective .for further I use -may be done quickly under the ,most adverseconditions, y.thus vminimizing the time-during which thesnow plow. is idle.
' The .assembly is further characterized by an interlocking ,connection between the wearV iplate ,andshoe which prevents the wear plate vfrom .becoming looseor ,displaced Withrespectto the shoe.. By providing lonay Sep arate vwear plate, the samemay be formed of Tany rdesired wearjresistant ,material, such as manganese steel, thus adapting the same for use overlong .periods o f time `under the most exactingconditions.
,Whilel have herein Vdescribedand upon the wardlyandangularly disposed arm portions havsaid shoe and plate in assembled relation, and means providing a dove-tailed connection between the end of said plate and shoe to prevent longitudinal displacement therebetween.
3. A :snow plow shoe assembly v;com,prising a shoe formed with a central base `portion'and outwardly and angularly disposed arm portions hav- Ling means for securing the assembly to the frame viding a dove-tailed connection between theend of said n plate 4and shoe 4to wprevent jlorlgitudinal displacement therebetween.
