8 Claims. (CI. 37-42) This invention pertains :to snow removal .equipment and more particularly to a :device for attachment to a road maintainer, a snow plow or other snow removal equipment which will be usable for removing the ridge of snow :laid up by such snow removal equipment in driveways or the like.
In the clearing of snow from highways and streets or the like, the usual technique is simply to push the snow from the roadway over to the edge of the road. This results in the piling up of a ridge of snow .all along the edge of the roadway. In most instances especially in open country this ridge causes no trouble. In towns and cities, however, much trouble can result from this ridge. For example, at driveways or other intersections, such ridges are extremely bothersome, and may be dangerous.
By our invention we provide a device attachable to the blade of a road maintainer, snow plow or the like, which device can be raised-out of service when not needed, but can be lowered to remove the snow in the ridge from the driveway or intersecting roadway, thus leaving the intersection clea-r. Various safety devices are provided :to provide a jful-l floating device which will not sufier severe damage upon impact with objects alongside the roadway.
A :clearer understanding of our invention in its embodiment may be had from a study of the following specification and the figures in which: 7
FIG. 1 is a rear elevational view of our device as attached to the blade of a road maintainer with a small part broken away to show underlying parts.
FIG. 2 is a view similar to FIG. 1 showing the wing in a raised position.

FIG. 4 is a detailed view of the attachment means on the blade with the wing removed.
' filG. ,5 is a view-similar to FIG. 4 showing the reverse side of .the attachment means.
FIG. 6 is a sectional view along line 6-6 of FIG. 1.
FIG. 7 is a view similar ;to FJG, 6 showing :the blade tilted lo the .position shown in FIG. 3
:8 is a front elevational view of the device as shown in FIG. 1, and- :FIG. 9 is .a detailed sectional View to an enlarged scale showing .the elevating :mechanism in three alternate positions.
Br-iefly our invention :comprises a wing attachment for a road maintainer, snow .plowm othersnow removal equipment. This attachment is removahly fastened to the end of the blade of the removal equipment .and has hydraulic or similar :mechanism ifor raising or lowering the wing. The wing is fixed at an angle to {the path of travel suohthat in its-operable position it will carry snow with it, and not allow it to drop ofi ithe -end [of the blade to pileup a ridge. Various safety means are embodied in the device to prevent breakage.
More specifically and in reference to the drawings, we have shown our device 'affixedito the blade 10 of aroad maintainer device. It will soon be apparent that (our invention could be ijust as easily attached :to .many other types of snow plows .or snow removal .equipment.
:Only a slight .modificatio-n of ;the blade iis p n-ceded in order ,to attach 10.111 device zto such ;a blade. Ears 1 1 3,231,991 Patented Feb. 1, 19.66
and ,a boss 12 (FIG. .4) may be welded to the blade 10. These are provided with holes for the reception of pins as will later appear.
Nearly all of the mechanism of my device is enclosed within a box-like carrier 13 which is atlixed to the blade 10 by means of a heavy pin 15 (FIGS. 4 and 5) extending through the boss 12 and ihtoug-h two bosses 16 on the carrier. The shear pin 15 is considerably weaker than the pin 14 for a purpose to be explained later.
As best shown in FIG. 9, the carrier 13 is formed to enclose a support arm 18 pivotally journalled on a lower axle 19. This arm 18 is a large rectangular member extending from the axle outwardly through a slotted end 20 of the carrier 13.
As is well known in the a t, the blade 10 is carried at an angle to the line of travel such that one end trails behind the other end for, the purpose of moving snow along the bladeto the edge of the road. The snow slides off the trailing end. Our device is adapted to be fixed :to the blade at this trailing end.
At a point about at the end of .the blade 10, the arm 18 is bent forward at 21 so that it forms an angle with the line of travel of the blade nearly opposite to the angle .of the blade 10. This is the preferred angle. will be apparent hereafter, however, that this :bend could be somewhat :less, and that the bend ,could be such that the .arm extends perpendicular to :the line of travel and that our .device would still operate successiully. Moreover the bend could also be greater, forming an even sharper angle to the line of travel without seriously interfering with the operation. Outboard .of this bend the auxiliary scraper blade or .wing 23 is fastened ,to the arm 18, by means described hereinafiter. However, it is now apparent that the scraper blade 23 will carry any snow along with it and not permit it to drop off the outer end with :the result that the snow will be collected on the w ng or scraper 23.
At a distance somewhatabove the ,axle 19 in the carrier .13, we provide an upper axle 24, on which is pivotally journalled a lift mechanism. This axle 24 may be located as shown .or may be dropped .down to the hole 22. This mechanism comprises principally a hydraulic cylinder device :25 adapted .to be connected to a controllable hydraulic pump, not :shown. The p o ro 26 extends :from (the piston within the cylinder and is adjustably eonnected to a pull rod 27 by means of a turn buckle "28. The pull rod 27 in turn is pivotally fastened .to ,a crank device 30.
'Mounted .on the arm :18 is a tubular slide 3=1. This slide is formed withan opening in which the crank device is adapted to slide longitudinally .of :the arm 18. The .crank .and :the opening in the slide are preferably formed with complementary surfaces such that no rotai n of n with respect t -.Qthe 1 -p h s surfaces may b mp y rectan u su a or th y m be sp ined, ik yed o :the l k t Pr n th el i relation. 'ltrshould be notedthatthis merely a preference and is not absolutely necessary because the structureof the slotted end '20 also holds the arm 18 and rods 1 26 and "27 .in .proper relationship.
Thearrn :18, as-,noted above ispivoted on theaxle .19 Sozthatitisfree to ,move arcuately -up anddown aLPOsitions remote from the axle ;19. Because of the freedom allowed by the sliding action between the ;crank 30 and the slide 31, the arm can rise without movement of the rods 26 and 27 as shown by the lower two positions shown in FIG. 9. It will be noted that in the lowest position the crank is moved as far to the left in the figure as possible. As the arm 18 is raised, and without movement of the rods 26 and 27, the crank 30 simply slides outwardly of the slide 31. This allows the arm to float freely above a certain point without movement of the piston within the hydraulic cylinder 25. However, by pulling the rod 26 into the cylinder 25 by hydraulic action, the crank 30 can be effectively shortened or pulled further to the left (in the figure) so that an edge 29 of one leg of the crank 30 engages the slide 31 in a hooked engagement. Further pulling of the rods will cause the arm to be pulled pivotally upwardly as illustrated by the upper position in FIG. 9. Thus, while the arm is free to float above any given position without movement of the piston within the cylinder, it can be effectively raised by hydraulic action if desired. As will be apparent to those skilled in the art, the raising of the scraper blade 23 would be done with shorter strokes of the rods 26 and 27 if the axle 24 were located at the hole 22. If speed is necessary or desirable, we canthus make it possible. It will be evident at this point that equivalent raising mechanism such as a cable pulling device could be used for this purpose and that we have only described our preferred mechanism.
As illustrated, the carrier 13 is open on top to allow the mechanism freedom of travel in this direction.
As stated above, the arm 18 carries the wing 23. In order to do this with safety, it is necessary that the wing 23 be tiltable so that if it should hit a surface irregularity such as a curbing or the like, it will simply tilt from the position shown in FIG. 6 to the position shown in FIG. 7 and then ride up and over the irregularity. In order to make our wing tiltable, we form the arm 18 to a cylindrical shape of circular cross section beyond the bend 21. Brackets 34 fixed to the wing 23 are journalled on the cylindrical end of the arm 18. These brackets are spaced apart so that the wing is carried on the arm without movement except a rotary movement about the arm 18. In order to control the rotary movement, we provide a spring loaded arrangement to urge the wing to its normal scraping position as shown best in FIG. 1 and FIG. 6. This springloaded mechanism includes a spring platform 35 fixed to the wing 23 and, for extra support, to the brackets 34. Bolt means 36 carrying spring engaging bases 37 are threaded through the platform 35 to provide adjustment of the springs as will appear. The springs 38 are compression type springs and are engaged between the base 37 and a bar 40 fixed to the arm 18. This bar 40 may be additionally supported by a fin 41 also fixedly attached to the arm 18. This fin 41 also extends upwardly above the arm and is formed as a stop device to hold the wing 23 in its normal use position and to prevent further rotation beyond that position under the pressure of the springs 38.
In use, our device is normally carried in its upper or carried position as illustrated in FIG. 2. It is raised and held here by means of the hydraulic lift mechanism previously described. As the plow or other snow removal equipment approaches a driveway, the wing 23 is lowered to the position illustrated in FIG. 1 which is the normal use position. At this position, the snow which was pre viously rolled off the end of the blade into a windrow or ridge along the edge of the road, is caught by the wing 23 and held on the wing or between the two blades. To assist in this we provide an outer end shield 44 (FIG. 8).
As soon as the driveway (or other roadway intersection) is passed, the wing may again be raised by the hydraulic mechanism as described. This causes the snow previously entrapped to be left at that point. Meanwhile the intersection, or driveway is free from any windrow or ridge of snow.
Among the safety features we provide for our device is a wing which fioats freely above the lower limit of operation. This was fully described in reference to FIG. 9 and will not be described again here except to call attention to it. It will be clear that when the wing 23 is lowered to ride along the ground, there might be gradual inclines up which the blade should be free to ride. This is completely provided for by my floating action.
If the surface irregularities are somewhat more than slight inclines, and if they be firmly fixed to the ground, then our provision of the tilting blade becomes effective. It will be noted that the engagement of the lower edge 45 (FIGS. 6 and 7) of the wing blade 23 with a fixed object as the blade moves forward will cause the blade to tilt to the position shown in FIG. 7 against the pressure of the springs 38. This pressure may be adjusted to the proper amount by use of the bolts 36 so that the blade will not tilt at every small protuberance, but will allow larger fixed objects to pass under the blade without damage to the main blade 10 or to other parts of the device. It will also be apparent that the floating action may also operate after the wing blade has tilted to cause the wing to clear the interfering object. As soon as the surface irregularity has been passed, the wing blade 23 snaps back to its original position, so that, in efiect, it oscillates around the arm 18.
In the event that the wing blade 23 should strike a pole or some large vertical object such that the previously described safety features would not be operative, then our provision of the shear pin 15 (FIG. 4) becomes important. As will be apparent, this pin 15 provides a frangible link in the mounting of the wing assembly. This pin will shear off upon impact of the wing blade with a fixed object, allowing the entire wing assembly to pivot rearwardly about the pin 14 to clear the struck object. Thus, even such an impact would do no damage to the structure as a whole, except for the shearing of the pin 15.
Thus it is apparent that our device is a very useful and practical device for ending an annoying situation in a great many northern communities.
