` 'Y i Another very-importantobject ofthe invention resides in the provision'off a snow'plow having a pair o'funiold boards secured together at their forwardends and diverging rear wardly fromeach other andconnected' together by a bracingstructure mounted Ona frame which includes Ineansyfor engaging theforward portion ofthe chassis v`or Viframe of .an automobile or truck; u

'A still'further veryfimportantobject of the invention resides 'in the provisionof a snow plow of this nature which is simple-in its construction, compact and convenient in `its l arrangementofparts, strong and durable, easy to manipulate, thoroughly eicientfand reliable in use, 'and otherwise well vadapted tothe purpose forwhich` it isdesigned.v l

i "With the above andnuinerous other objects in viewasrwill appear as the descriptionproceeds', the invention resides in certain novel `features of construction,` and inthe 'combination and arrangement ef partsfas will be here-v inafter more Vfully described and claimed; y

A cross rod 26 is engaged with the lower portions ot interinediate parts ofthe shares 5 and rods 27 are pivotally enga-ged therewith and extend rearwardly and are pivozjally engaged witii the lower extremities of the .arms Y.

From the `above detailed description it will be seen that i have devised a plow structure which may be effectively, eiiiciently, easily and readily mounted onv the front end o'ian automobile frame wherein the shares thereoil may be raised or lowered so as to change the angle thereot` in respect to the ground to ob tain the 'most ellicient operation under vay ing circumstances. Such change in a i. accoinlilished by rocking the ieri the levers 23 push.

which in turn ioc i y pulling on the links or rods 2T to swing the shareson the pivots connecting the bars i2 with the bracket 1l and `also causiiig a slight rockiiiginotion on pivot connections 30 between the 4front extremities ot the bars i9 and the rear intermeeiate i portions oi the bars l2.

lt` is thonglitthat the construction, operH atioii,utilit v and advantages ol his invention will now be quite i apiL arent to those skilledr in this art wit-hout a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely tor the purposes of exempliiicaticn since in actual practice it attains the features otadvantage enumerated as desirable in the statement of the invention and the above description.

It will be Vapparent` that changes in the details oit construction7 in the combination and arrangement otparts may be resorted to without departing 'troni the spirit or scope o'l the invention as hereinafter claimed or sacrilicingany of its advantages.
