Abstract
Abstract A snow handling device is disclosed in which a carriage has a jack to which a central portion of the handle of a snow shovel is pivotally connected both to rotate and for axial movement relative thereto and a forward extension to which the handle is connected by a link permitting the handle to be turned but limiting its axial movement. When the shovel is full, the operator depresses the rear portion of the handle with the lifting of the shovel enabling the device to be easily moved and also erecting the link to hold the shovel in an elevated position relative to the forward extension. The jack may then be operated by again raising the rear portion of the handle to establish a higher dumping position of the shovel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
218 words
A snow handling device for use with a shovel, a carriage including a forward extension and a jack, said jack including a lower part, a connection between said lower part to the carriage fixing it in a predetermined upwardly disposed position, an upper part connected thereto to enable it to be pulled upwardly to provide an extended jack position, and means releasably interlocking said parts in said extended position, a holder dimensioned to slidably and rotatably support the shovel handle and pivotally connected to said upper jack part with its axis transversely of the carriage, and a link pivotally connected to said extension to swing upwardly and forwardly thereof from an inoperative position into a predetermined, forwardly inclined shovel-supporting position, said link including a connection attachable to said handle adjacent the scoop of the shovel to limit lengthwise movement but permitting the turning thereof, whereby with the handle attached to the device, the link may be erected into its shovel supporting position by depressing the rear portion of the handle as an incident to lifting the shovel into a first dumping position and the jack extended by again raising the handle a predetermined extent after the extension has engaged the ground thus to provide an elevated dumping position when the rear portion of the handle is again depressed.
Claim 2
Dependent Claim
218 words
A snow handling device for use with a shovel, a carriage including a forward extension and a jack, said jack including a lower part, a connection between said lower part to the carriage fixing it in a predetermined upwardly disposed position, an upper part connected thereto to enable it to be pulled upwardly to provide an extended jack position, and means releasably interlocking said parts in said extended position, a holder dimensioned to slidably and rotatably support the shovel handle and pivotally connected to said upper jack part with its axis transversely of the carriage, and a link pivotally connected to said extension to swing upwardly and forwardly thereof from an inoperative position into a predetermined, forwardly inclined shovel-supporting position, said link including a connection attachable to said handle adjacent the scoop of the shovel to limit lengthwise movement but permitting the turning thereof, whereby with the handle attached to the device, the link may be erected into its shovel supporting position by depressing the rear portion of the handle as an incident to lifting the shovel into a first dumping position and the jack extended by again raising the handle a predetermined extent after the extension has engaged the ground thus to provide an elevated dumping position when the rear portion of the handle is again depressed.
Claim 3
Dependent Claim
16 words
The snow handling device of claim 1 in which the length of the link is adjustable.
Claim 4
Dependent Claim
29 words
The snow handling device of claim 1 in which, when the forward extension of the carriage rests on the ground, the jack is forwardly and upwardly inclined when erected.
Claim 5
Dependent Claim
42 words
The snow handling device of claim 1 in which the connection is adjustable to enable said predetermined position to be varied between a position substantially at right angles to the carriage and a position in which it is forwardly and upwardly inclined.
Claim 6
Dependent Claim
79 words
The snow handling device of claim 4 in which the connection includes a vertical plate fixed lengthwise on the carriage, the lower part of the jack is pivotally connected to the plate, the plate has an arcuate series of holes concentric with the pivot axis, and a connection between the lower part of the jack and the plate through a selected one of the holes of the series fixes the desired angular relation of the jack to the carriage.
Claim 7
Dependent Claim
30 words
The snow handling device of claim 1 in which the jack is of a type that once extended is unlatched by once again raising the rear end of the handle.
Claim 8
Dependent Claim
48 words
The snow handling device of claim 1 in which the jack is of the type in which the latch interconnecting the upper and lower jack parts when the jack is extended is yieldably held in its operative position and includes a release manually operable to disengage the latch.
Claim 9
Dependent Claim
203 words
A snow handling device comprising a shovel, a carriage including a forward extension and a jack, said jack including a fixed lower part, an upper part connected thereto to enable it to be pulled upwardly to provide an extended jack position, and means releasably interlocking said parts in said extended position, a holder pivotally connected to said upper jack part with its axis transversely of the carriage, the handle of said shovel extending freely through said holder to permit it to be turned and slid lengthwise relative thereto, and a link pivotally connected to said extension to swing upwardly and forwardly thereof from an inoperative position into a predetermined, forwardly inclined shovel-supporting position, and a connection between said link and the handle of the shovel adjacent its scoop limiting lengthwise movement but permitting the turning thereof, whereby the link may be erected into its shovel supporting position by depressing the rear portion of the handle as an incident to lifting the shovel into a first dumping position and the jack extended by again raising the handle a predetermIned extent after the extension has engaged the ground thus to provide an elevated dumping position when the rear portion of the handle is again depressed.
Claim 10
Dependent Claim
203 words
A snow handling device comprising a shovel, a carriage including a forward extension and a jack, said jack including a fixed lower part, an upper part connected thereto to enable it to be pulled upwardly to provide an extended jack position, and means releasably interlocking said parts in said extended position, a holder pivotally connected to said upper jack part with its axis transversely of the carriage, the handle of said shovel extending freely through said holder to permit it to be turned and slid lengthwise relative thereto, and a link pivotally connected to said extension to swing upwardly and forwardly thereof from an inoperative position into a predetermined, forwardly inclined shovel-supporting position, and a connection between said link and the handle of the shovel adjacent its scoop limiting lengthwise movement but permitting the turning thereof, whereby the link may be erected into its shovel supporting position by depressing the rear portion of the handle as an incident to lifting the shovel into a first dumping position and the jack extended by again raising the handle a predetermIned extent after the extension has engaged the ground thus to provide an elevated dumping position when the rear portion of the handle is again depressed.
Claim 11
Dependent Claim
20 words
The snow handling device of claim 8 in which the shovel handle is of substantial length and includes detachable sections.
