Among such proposals is that of mounting a shovel on a twowheeled carriage in a manner enabling the carriage to be pushed forwardly with the shovel in a position then to be loaded, the rear portion of the handle depressed to raise the shovel, and the handle turned to dump the snow carried by the shovel. See for example U. S. Pat. Nos. 2,846,785 and 2,520,606.
While such proposals are useful, they are not adapted for use where the snow to be shoveled is deep or where, adjacent the area to be cleaned, there are substantial snow banks.
THE PRESENT INVENTION Snow handling devices in accordance with the invention do not have the above referred-to limitation on their use since, when thesho'vel of such a device is loaded, its dumping position can be elevated if necessary or desirable.
This result is attained by providing the carriage with a jack to which a-central portion of ashovel handle is pivotally connected in a manner permitting it to be turned and to be moved axially relative thereto. The carriage has a forward extension to which a link is pivotally connected to swing forwardly and upwardly from a firstposition beyond center into a predetermined second position. The link is connected to the handle close to the scoop of the shovel in a manner permitting the handle to be turned to dump the scoop contents but limiting the extent to which the handle may be moved axially; g
In use, once the device has been pushed forwardly to load its shovel, the rear portion of the handle is depressed raising the scoop of the shovel so that the device may be easily moved and, at the same time, shifting the link from its first into its forward,secnd ,position so that the link, forward extension, jack and the portion of the handle between the jack and the link establish a quadrilateral held against collapse by the weight of the loaded shovel holding thelink in its second position. If the device cannot then provide a dumping position that is high enough, the rear portion of the handle is. raised with the forward extension coming in contact with the ground and the jack becoming extended so that when the rear of the handle is again depressed, the dumping position iselevatedl BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings, there is shown a preferred embodiment of the invention of which FIG. 1 is a side view of the device showing, in solid lines, the load-receiving position thereof and, in dotted lines, the erection of the shovel-supporting link;

FIG. 8 is a like view of a jack in accordance with another embodiment of the invention.
In the embodiment of the invention illustrated by FIGS. 1 3 of the drawings, the device consists of a carriage 10 of a type supported by a pair of wheels 11. The carriage 10 includes a forward extension 12 and an upwardly extending jack, generally indicated at 13 and desirably defining with the forward extension an angle of less than with the smaller the size, the greater the resulting lift.
The jack 13, see FIGS. 4 7, includes a U-shaped lower section 14 whose sides 14A have inturned margins and a U-shaped upper section 15 whose sides 15A also which inturned margins and which is dimensioned to be a slidable fit in the section 14 with the inturned margins of each section in engagement with the other section so that the sections are spaced apart. The upper section 15 normally rests on a stop 16 with which the lower section is provided. The carriage 10 is shown as having a plate 17 to which the jack section 14 is connected by a pivot 18 an;d which has an arcuate series of holes 19 with the jack section 14 secured by a bolt 20 through a selected one of which to fix the jackin a selected angular relationship relative to the carriage. The upper jack section 15 has a split sleeve 21 connected to its upper end by a pivot22.
At the front end of the forward extension 12 there is a U-shaped holder 23 to which a link, generally indicated at 24 is connected by a transverse pivot 25 so that it may swing between its full and dotted line positions shown in FIG. 1. In its full line or first position, the link 24 is rearwardly disposed. In its dotted line or second position, the link 24 has been swung upwardly and forwardly beyond center to define an angle of more than 90 with the extension 12 held by the closed end of the holder 23 against swinging further forwardly. At its upper end, the link 24 is provided with a split sleeve 26 connected thereto by a transverse loop 27 permitting the sleeve 26 to be turned to a substantial extent. The link 24 is desirably adjustable as to its length and to that end is shown as including sections 24A and 24B interconnected by bolts 24C extending through selected ones of the holes of a series thereof with which each link section is provided.
A shovel, generally indicated at 28 has a relatively long handle 29 extending through the sleeves 21 and 26 with the sleeve 21 freely receiving the handle 29 so that it may be turned or moved axially relatively therewith and with the sleeve 26 clamped thereto to limit the extent to which it may be moved axially. The clamped position of the sleeve 26 is so close to the scoop 30 of the shovel 28 that, when the link 24 is in its first position,
its holder 23 is under said scoop. The handle 29 may include detachable end portions with a joint conveniently of the ferrule type.
In practice, the device is pushed forwardly into the snow to load the shovel, for that purpose utilizing the rear portion of the handle 29. The rear end of the handle 29 is then depressed to enable the device to be more easily moved and as the loaded scoope 30 is raised, the link 24 is pulled forwardly into its second position with the handle 29 sliding forwardly through the sleeve 21 as the latter is pivoted. It will be noted that the link 24, the forward extension 12, the jack l3 and the portion of the handle 29 between the jack and the link define a quadrilateral held against collapse by the loaded shovel scoop 30. The device may then be pushed to the dumping area and the handle 29 then turned to an extent sufficient to dump the snow. When the device is pulled rearwardly by the handle, the quadrilateral collapses with the link 24 swinging rearwardly and downwardly with the parts returning to their FIG. 1 positions.
Turning again to FIGS. 4 7, it will be noted that the jack sections 14 and 15 are assembled so that a latch 31 pivotally connected by a pivot 32 to the jack section 14 adjacent its upper end is within the extension 15 with its pivot axis close to one of the sides 15A thereof which side has a lengthwise slot 158 thereon. The corresponding one of the sides 14A of the jack section 14 also has a lengthwise slot 143. The slots 14B and 15B are dimensioned topermit the ends of the latch 31 to extend therethrough as the latch is turned with said slots in registry. The ends of the latch 31 are notched to provide arms 31A and 318 whose proximate surfaces define an angle of about 90 with the arms 31A being somewhat longer than the arms 318. The jack section 15 has an actuator 32 fixed on its inner surface adjacent its lower end in a position to engage with and turn the latch 31 to a predetermined extent each time the jack section 15 is fully extended by the raising of the rear portion of the handle 29.
Except when the jack 13 is extended, the latch 31 is positioned as shown in FIG. 7 so that the section 15 may be freely moved in either direction. When the section 15 is fully raised, the actuator 32 strikes the de pending arm 31A and so turns the latch 31 as to bring the upwardly disposed arm 31 into the path of the upper edge of the slot 158 when the section 15 slides downwardly a short distance which then turns the latch 31 into its operative position shown in FIG. 5. When the jack section 15 is again raised, the actuator 32 reengages the latch 31 and this time turns it to present an arm 313 to the upper edge of the slot 15B as the jack section 15 slides downwardly with the latch 31 then being turned from its FIG. 6 into its FIG. 7 position.
The jack of the device may be of other types and another such jack is generally indicated at 33 in FIG. 8 with the lower section 34 having the upper section 35 slidable therein. The section 34 has a locking recess 36 while the section 35 has a bracket 37 pivotally supporting a bell crank 38 connected to a latch 39 yieldably urged into a recess entering position by a spring 40. As the rear portion of the shovel is raised to extend the jack, the latch 39 rides along the section 34 until it enters the latching recess 36 to then interlock the sections in their extended relationship. The jack is returned to its shortened position by actuating the bell crank 38 to withdraw the latch 39.
Dimensions are now referred to by way of illustration and not by way of limitation. With a shovel handle seven feet long clamped by the sleeve 26 and loosely held about midway between its ends by the sleeve 21 and with a link 24 of about a foot in length and the jack 13, in its shortened position about two feet inlength, the rear end of the handle is approximately four feet above the ground when the device is pushed forwardly to load the shovel. When the rear portion of the handle is depressed to bring the handle horizontal, the shovel is, say, two feet above the ground in its dumping position. With the rear of the handle 29 raised, the forward extension engages the ground and the jack is extended to its full length, say three and a half feet. The rear end of the handle is then about five and one-half feet above the ground but when it is pulled into a horizontal position, the dumping position has been substantially elevated.
