HARRY H. GEARK, OE DETROIT, -MIGHIGAN.

AUTOMOBILE-SNOWPLOW.

I i Specification of Letters Patent. Patented J 11 1921 Application filed October 16, 1918. Serial No. 258,421.

To all whom it may concern Be it known that I, HARRY H. CLARK, a

citizen of the United States, residin at Detroit, in the county of Wayne, tate of Michigan, have invented certain new and useful Improvements in Automobile-Snowplows; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in snow plows and particularly to snow plows which are arranged for attachment to automobiles.

One object of the present invention is to provide a noveland improved device of this character which can be easily and quickly.

attached to or removed from any automobile and which will clear the road, ahead of the automobile, of snow.

Another object is to provide a-novel and improved device of this character whereby provide a novel and improved device of this character whereby the depth of the snow to be removed can be easily and efiiciently regulated.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanyingdrawing.

In the drawing:

Figure 1 is a top planview of the front portion of an automobile showing my "invention applied thereto.

Fig. 2 is a side elevation of the same. Fig. 3 is a vertical transverse sectional view taken on the staggered or irregular line 33 of Fig. 1.

Fig. lis a vertical longitudinal sectional view taken on the line 4-4 of Fig. 1.

Referring particularly to the acoompanydrawing, 10 represents the front axis of the automobile, 11 the radiator, and 12 the filling tube of the radiator, in connection w1th which my invention is particularly adapted for use.

Disposed on the front axle, and secured thereto by means of the U-bolts 13, are the furcated, as at 15, and receiving therein the rear end of an arm or link 16. This arm is pivotally connected in the bifurcation so that said arm will swing in avertical plane, as will be plainly seen from an inspection of the drawlng. The forward end of each of the arms 16 is pivotally engaged in the bifurcated portion of a bolt 17. A pair of forwardly converging blades 18, which are concavo-convex in cross section, are disposed in front of the automobile, and each blade plates 14, each having its forward end bihas one of the bolts 17 Secured through the intermediate portion thereof. Each of the blades has an angle member 19 secured to vthe inner face, slightly in rear of the bolt 17, and extending transversely between the blades, and secured to said anglemembers by bolts 20, ina brace rod 21, said rod holding the blades in proper position in front of the automobile. The forward ends of the blades are hinged together as at 22, whereby when the U-bolts 13 are removed the two blades may be folded together for conven: iencein storing or shipping. Extending rearwardly from each of the blades, at.

points immediately in rear of the bolts 17, are the arms 23 to whichthe shoes 24 are attached. Each of these shoes has its forward lower portion curved inthe manner of a sled runner so that it will easily glide over the snow, and formed on the upper edge of the shoe or runner are the arms 25-. These arms are formed with the longitudinal-series of openings 26 for the reception of bolts 27 which also pass through said arms 23, to hold the runners in proper position, and whereby they may be adjusted to I the proper height to raise or lower the scraping blades. Carried by the forward apex of the device is an eye-bolt 28, and engaged with the eye of said bolt is the forward lower end of a rod 29, the other end of said rod being connected to one end of a coilspring 30. A second rod 31 is connected to the other end of the spring and has its remaining end formed witha loop or eye 32 which is engaged on the filling tube of the radiator. turnbuckle 33 is dis posed in the intermediate portion of the rod 31 whereby the rod may be adjusted and the tension' of thespring increased or. de-

tomobile.

' cording to the character-of the 'snow,

whether the same is soft or hard. In light or soft snows the depth would be greater than when the snow is of a dry or'hard character. At the forward end of the scraper there is disposed an arm 34, similar to the arms 23, and adjustably secured to this arm is a runner or shoe 35.

Thus as the automobile is driven forward,

. the scraper blades scrape the snow and dewould have fiect it to the sides of the road, the blades being disposed at such a. height from the ground that several inches of snow is left on the road for sleighin This snow left on the ground, will be su cient to permit the rear wheels properly to drive the automobile, which been hard, or impossible in deeper snow. Thus the device serves a double purpose first, by cleaning enough snow from the road to permit proper tractive action of the drive wheels of the automobile, and second, to leave enough snow on the road to permit the use of slei hs.

Furthermore, by reason 0 the construction and arrangement of the runners, with the forward ends extending forwardly of the lower edge of the moldboard, and being of the automobile to operatev upturned in front thereof, such runners will encounter any obstruction and'lift the moldboard whereby the moldboard will be prevented from striking such obstruction.

,It will be understood that this device is also especially adapted for use with large automobile trucks, in cities to. clean the snow from the streets, and in this case, the blades will be lowered so as to scrape the snow entirely from the surface of the.

paving.

What is claimed is:

A snow plow comprising a double moldboard, means for detachably supporting the plow on the front of a motor driven vehicle,

inwardly extending brackets carried by the inner faces and within the angle of the moldboard of the plow, runneis disposed'in parallel relation to each other and extending forwardly and rearwardly beneath the moldboard, vertical stems on the runners ad justably engaged with the brackets whereby the runners are capable of being raised and lowered to hold the moldboard at different distances above the ground and whereby various depths-of snow will be left on the EARL W'.
