`of the invention, such as will' enable others skilled in the art towhich it appertains to make and use the same. Y

This inventionrelates to snow'pl'ows, and

more particularly to V'snow plowing devices adapted to be attached toft e forward end of an automobile, an object of the invention,

being the provision of snow lowing means having rotar fan wheels, said means being readily attac able to the chassis frame and coupled with the cranking shaft to be driven thereby. A

Y A further ob'ect of the invention, is to provide an attac ment of the classfdescribed, which may be controlled from the seat of the automobile and which will be adjustable, so

-that it maybe held raised from the ground at various 'tions A still urther object of the invention is lto provide, as an attachment to an automobile or truck, a `plow member for scooping conveying itlaterally to rotary expellers,the p ow member being formed to constitutes guiding shield partly encircling the expellers.

To this end the inventionl consists in the 36 construction, combination and ar ment of rts hereinafter? described andc aimed.
