UHTED FRANK lvI. GRADY, OF BUTTE, MONTANA.

REVERSIBLE SNOW'PLOW'.

Application filed January 2, 1924.

To all whom it may concern: 1

Be it known that I, FRANK 1i. GRADY, a citizen of the United States, and resident of Butte, in the county of Silver Bow and State of Montana, have invented certain new and useful Improvements in Reversible Snowplows.

This invention relates to street-cleaning devices especially adapted for use in connection with snow though not necessarily restricted to such use.

Briefly stated,- an important object of this invention is to provide a street-cleaning device for removing snow and the like which is provided with simple means whereby the blade may be securely and positively held in an adjusted position.

A further object is to provide a. streetcleaning device in which the blade may be adjusted from a point along the handle so that it is not necessary for the operator to handle the blade or the attaching means of the same.

A further object is to provide a cleaning device or snow-plow which is of highly simplified construction, durable in use and cheap to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective of the improved street-cleaning device.

Figure 2 is a fragmentary front elevation illustrating in full and dotted lines the various positions in which the blade may be secured.

Figure 3 is a detail transverse sectional view illustrating the adjusting means.

Figure 4 is a detail side elevation illustrating a hand-operated crank by means of which a locking pawl embodied in the invention may be released during the adjustment of theblade.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a blade curved transversely so that the same may pick up a quantity of snow. It is to be understood that the blade may be otherwise formed to meet operating conditions without departing from the spirit of the invention.

Serial No. 683,988.

Figures 1 and 3 illustrate that the intermediate portion of the blade 5 is connected to the lower end of a shank 6 by means of a pivot bolt 7. It is thus seen that the shank 6 may be adjusted with relation to; the blade.

To hold the shank 6 of the handle 2 in an.

member 20 is in the nature of a length of metal riveted at its ends to the shank and having its intermediate portion offset for the reception of the rack 14. By reason of this construction the guide member 20 not only serves as a means to connect the intermediate portion of the rack 14.- to the shank but also a guide for the dog 9.

The dog 9 may be moved to its inoperative position by means of a link 23 in the nature of a length of wire having its rear portion connected to one of the branches of a crank 25. The crank 25 is pivoted as indicated at 26 to an attaching band 27 mounted on the intermediate portion of the handle at a point where the operator may conveniently grasp one of the branches of the crank when it is desired to adjust the blade.

Attention is directed to the fact that the spring 220 which urges the dog to its operative position is arranged behind the blade and is consequently protected from engagement with the material picked up by the blade. The dog 9 and associated elements are also arranged behind the blade and are protected thereby.

In operation, when it is desired to adjust the blade with respect to the handle it is merely necessary to grasp the outer branch of the crank 25 and draw the same rearwardly so that the dog 9 will be moved to its inoperative position. The handle may now be swung to the desired position and the dog 9 will enter one of the notches so as to securely and positively hold the parts in an adjusted position. The material being handled is not likely to engage the dog 9 and move the same to its inoperative position because as previously stated the dog is arranged rearwardly of and is protected by the blade.

A snow-plow or shovel constructed in accordance With this invention is extremely durable owing to the arrangement of the parts and the fact that the blade may be quickly adjusted makes it possible to force the snow either to the right or to the-left in making a pathway.

Having thus described the invention, what is claimed is 1. A cleaning device of the character specified comprising a blade, a shank pivoted to the intermediate portion of the blade, a handle connected to the shank, a notched rack connected at its ends to the blades d extending across said shank, and a springactnated dog carried by the shank to engage the notched rack and thereby hold the blade in an adjusted position with respect to the handle.

2. A cleaning device of the character specified comprising an elongated blade, a shank pivoted'to the intermediate portion of the blade, a handle connected to the shank, a rack connected at its ends to said blade and extended across said shank, a bracket carried by said shank, a dog pivoted to said bracket and adapted to engage said rack, and a spring connected to said dog for urging the same into engagement With the rack, said spring and said dog be ing, arianged re-arwar'dly 0t and protected by said blade.

3. A cleaning device of the character specified comprising an elongated blade, a handle having a shank pivoted to said blade, a longitudinally curved rack extending across said shank, a guide member connecting said rack to said shank, a dog having pivotal connectionwith said shank and en gaging said. rack, said ,guide-inen'iber being provided with aslotrece iving said dog, a coil spring connected to said dog and said shank and urging the dog to operative position, said spring and said dog being arranged rearwardly of and protected by said blade, a link connected to said dog, and a crank carried by the handle and having con nection with said link.

4. A snow removing device comprising a transversely curvedblade of elongated formation, a handle having pivotal connection with thebla-de, av rack carried by the blade, spring means engaging the rack for holding the handle in a set position With respect to the rack, and a hand-operated member on the intermediate portion of the handle and connected with the spring means for disengaging it from the rack.
