(Cl. S7- 53) Application June 4,

2 Claims.

The present invention relates to an improved snow plow and scraper, and aims to provide a construction having substantial rigidity to withstand the rough usage encountered by articles of this character and which may be easily manually operated.

Another object of the invention is to provide a construction which may be adjusted to perform the function of either a scraper or a path clearer.

Another object ci the invention is to provide a construction of this character which may be stored or shipped in a collapsed condition and readily opened up for usetas occasion requires.

An additional object of the invention is to provide a wheel or roller supporting means ior the scraper or plow which substantially adds to the facility with which the device may be utilized.

An important feature oi the invention resides in fixedly supporting the wheel or roller in a manner which allows the construction to be collapsed without the wheel constituting an obstruction. Also, the roller` supporting means forms a part of the means for allowing the plow to be adjusted for purposes of a scraper or a path clearer.

Referring to the drawings:

Figure 1 is a rear view in perspective oi" the plow with the handle bar partly broken away, and showing the device arranged to clear a path,

Figure 2 is a front perspective view showing the plow similarly arranged to clear a path,

Figure 3 is a sectional view showing the wheel or roller mounting on the handle, and

Figure 4 is a front perspective view of the plow arranged as a scraper.

In Figures l and 2 a bar I0 carries at its lower end an integral vertically extending wing support or pintle I I. In some cases the pintle I I is welded to the end or the bar It. It will be noted that the bar I extends laterally with respect to the pintle and in a substantially horizontal relation thereto. Hingedly or pivotally carried by the pintle ll are the wings I2 and I3 of the plow or scraper. Each wing carries upper and lower strap iron hinge members It and I5 which are secured to the wings, as shown by means of bolts I6, and the curled pintle receiving portions Il of the strap members Ifl are so disposed and received on the wing support II that a pair on one wing, for example, the wing I3, is disposed between the other or outer pair of curled pintle receiving portions i3 of the other wing I4 whereby the wings are held on the vertical pintle Without -danger of displacement, and yet have free swinging movement for adjustment to operative posi- Chicago, Ill., assigner to Mare- Ill.,

tion or Jfor collapsing the wings when storing or shipping the plow.

The wings are provided with outwardly bent portions I9 and 20, the lower portions I9 constituting scraper plates and the upper portions 20 constituting guards to prevent the snow from creeping over the wings. i

Each of the wings intermediate its body portion and more nearly adjacent the lower edge is provided with a bracket 2| having an opening 22, and the bar I0 is provided remote from the pintle il with a bracket 23 extending on opposite sides of the handle to which it is bolted or welded. spaced openings 24 are provided on each side of the bracket 23.

The bar I0 at substantially the juncture J of its horizontally extending portion I0 and its integral upwardly bent handle pcrtion Ill, e. g., at the lower end of this latter portion, is provided with an opening 25, as shown in Figure 3, through which extends a shaft 26. One end of the shaft is curled into a hook or opening 21 longitudinally spaced on the bar Ill from the bracket 23 and the opposite end 28 forms a bearing or support for the wheel or roller 29. The roller 29 is received on the shaft 28, as shown in Figure 3, and preferably has a ball bearing mounting 30. The roller is supported for rotating movement upon engagement with the ground by the construction described, and is held Xedly in position by reason of the loop or hook 2'I constituting a stop on one end of the shaft, and the nut 3| engaging the opposite threaded end 32 oi the shaft. A washer 33 is included between the nut 3l and the hub of the wheel, and also between the bar I0 and the adjacent hub portion, as shown in Figure 3.

A pair of link members or rods 35 are provided, as shown in Figure 1, and one link member has one end engaged in the opening 22 of bracket 2| on the wing I2 and the other end engaged in the loop 21 of the shaft 26. The other link member, which is relatively shorter, has one end engaged in the opening 24 of the bracket 23 on the bar, and the other end engaged in the opening 22 of the bracket on the wing I3. The arrangement shown in Figure 1 of the relatively longer and shorter links may be reversed, i. e., with the longer link engaging the bracket on the wing I3, and the shorter link engaging the bracket on the wing I2, according to whether it is desired to adjust the angular relation of the wings in one direction or the other in clearing a path.

In Figure 4 I have shown the invention adjusted to act as a scraper with the wings in straight line relation, and in this construction both of the links 35 have one end engaged in the opening of a bracket of the respective wings, and their other ends engaged in the openings 24 of Athe bracket 23 on the bar l0.

It will be observed that to collapse the construction, it is only necessary to remove one end of each link from engagement with one of the openings on the wing or the bar Ill, and the construction may be readily opened-up for operation by simply having the links engage in the respective openings, as described in connection with Figures 1 and 4. When collapsed, the wings fold against the bar I and the wheel 2 9 thus becomes lined up with folded wings so that a fiat article is presented.

The plow is preferably constructed entirely of metal, and possesses the necessary rigidity to assure a long life. It is preferred to employ the roller 29, although in some cases, it may be substituted by a runner, or entirely eliminated.

The bar l0 supports all of the parts of the construction and at its free end is provided with suitable handle grips 38. If desired, the plow may be attached to a vehicle or operated by a prime mover.

Referring to Figure 2, it is to be noted that there is an opening O between the ends 39 of the outwardly bent bottom scraper portions I9 when the plow is used to clear a path. Such opening is not objectionable, but there are some cases where it is desirable to close the same. Various means may be used to close this opening.

I claim:

1. A kSnow plow or scraper comprising a bar, wings pivotally mounted on said bar, means con necting the wings to the bar at a point remote from the pivotal mounting, said connecting on said support.

2,. A snow plow or scraper comprising a bar, wings pivotally mounted on said bar, means connecting the wings to the bar at a point remote from the pivotal mounting, said connecting carried on said support and disposed in line with the folded relation of the wings whereby when the plow or scraper is collapsed with the wings in folded position a at article is obtained.
