if Appli cation August 11, 1941s; malar a-6 9 1 present invention relates generally to snow removal apparatus, and more particularly to a novel device which maybe employed effectively to clear snow, sleet,-and ice from the lower section .of roofs and, from. guttersby an" individual standing within a building.

In all climates where snowfal lls' anag ious' condition I now arises whenever' large amounts of snow accumulate upon the'roofs'and in the gutters, of buildings, particularly dwelling houses having sloping roofs. As a result of alternate thawing and freezing weather aided by the warmth of the roof itself, the snow gradually changes to water which trickles down toward the colder snow on the eaves or gutters which tends to soak it up and freeze into a solid dam of ice. This causes such water thereafter to back .up under the slates or shingles and 'to leak down into the building, thus damaging walls and ceilings.

This is most annoying and often a very costly condition, and as far as I am aware there have never been any mechanical means devised which will overcome this diificulty other than the tedious and dangerous undertaking of climbing up a ladder and removing the snow from the outside.

By my novel construction, a person can readily free his roofs from snow after each storm without any appreciable effort and without going out in the cold to effect the same. By standing on the floor below the roof, opening the window, and adjusting my apparatus into operative position, he may scrape off the snow by merely manipulating a convenient hand lever.

A main object of my invention, therefore, is to provide a foldable unit which may be projected thru an open window, manipulated into roof-engaging position and operated by a person standing inside a building, and which includes provision for removing snow, slush, ice, or the like.

Another prime object of my invention pertains to the arrangements of parts whereby my apparatus may be utilized with the standard window construction, employing either the windowsill, the tops of both windowsashes, or a separate support as a fulcrum means.

A further important object of my invention resides in the versatile characteristics of my invention whereby the same may comprise a complete interconnected utilize a standard rake, hoe, or the like tool in attached association therewith.

Still further objects of my invention relate unit, or may be adapted toto the simplicity of'its construction, its adaptability, and its inexpensive-cost.

Fig. 3 is a cross-sectional view on the line 3 -3 In the drawings whereinlike flgures represent likefparts, the' numeral'lfl designates gen- 15 1 struction including a roof I'l gutter l2, window- "frame '|4 upper and lower window-sashes l5 "and 5 respectively, windowsill l1, side wall l8,

erally a building having the usual standard conand flooring l9. v

"eferring' specifically to Figs. 1, 2, and 3 which illustrate the i'ireferred-form of my invention, I show my snow removal device as comprising one complete foldable unit in combination with a separate support therefor and present a clear picture of the same in operative position.

In this particular form, I provide a suitable snow-removing element, preferably a rake-like member, as shown, comprising a shaft portion 20 and a rake portion 2|, said shaft portion 20 being appropriately curved or bent and of sufficient length to be projected above the roof H by an operator 22 so that the rake portion 2| will properly contact the snow deposit 23, and be in desired snow-removing position. The bottom of said shaft 20 is pivotally secured to a socket member 24, into which is threaded or otherwise attached one end of a lower supporting rod 25, the other end of which rod is formed in the shape of a body brace 26, preferably curved, as shown, to fit conveniently against the thigh of the operator 22. Adjustably secured about the shaft 20 above the member 24 is a collar 28, the open part of which encloses one end of an upper operating rod 30 and is pivotally connected therewith by a suitable adjusting pin 29. I

The opposite end of said rod 30 is pivotally fastened to a cross-lever 32, said lever, in turn, being formed with hand grips 33 and 34 on each end thereof, the lower grip 33 being pivotally connected with said rod 25, as clearly shown.

If desired, I may rest the lower rod 25 on the inner part of the window sill l1, using the same as a fulcrum, or I may provide a convenient support such as shown in Fig. 2, comprising a unit in proper balance during the snow-removing operation, I provide a suitable strap 39 which is adapted to fit'over the shoulder of the operator 22 and which is attached to the rod 25 adjacent the body brace 26 by any appropriate means such as a rivet or pin 40.

When utilizing my novel apparatus to clear a ccumulation of snow 23 from the lowerse'ction' of a roof ll adjacent the gutter l2, I-ini'tially raise the lower sash l6 and, if desired, .secure the clamp 35 to the sill I1. I then project my unit 'thru the thus open window while yet in folded zassem-lbly with the shaft portion 20, supporting rod 25, operating rod 30, and operating lever-32 insubstantially parallel relation, positioning the rod 25 between the rollers Gil-38 on the postSl, or.resting the same on the windowsill l1. Thus.v arranged l operate the -lever-32 into vertical position by means .of the. handles33=and 34, thereby automatically elevating the' shaft. 20 suffi -.ciently-- so that by slight manipulation I; may .ma-neuver the rake portion 21 into contact with the snow 23, as desired. l

N ow, flitting the strap-#22 over my shoulder and adjusting the brace 26 against my thigh, I; am

.prepared to commence thesnow-removal operav.tion. :Ofmcourse, such snow clearance may be effected in; many ways but I find a practical method isito grasp each grip 33 and 34, and with the lever :32 in vertical position, holding such grips rigidly while advancing a few steps toward the open window until the rake portion -2l carries the snow 23, beyond the roof- II and gutter I 2.

Therake2l is then remaneuvered intosnow-removing location on the roof II, and the process repeated.

It will further be apparent that a person operating my invention need have no skill to manipulate the same but may easily maneuver the rake, hoe, or similar scraping tool into desired snowremoving position on the roof. In fact, with my device, an operator may whip the rake or hoe with sufiicient force to penetrate crusty snow or ice, which is often a'mostd'es'irable consideration.

Iclaim:

As a new article of manufacture, snow-removal apparatus of the kind described for use on build- .ingv roofs and operable thru a window from within the building, comprising in foldable association a horizontal window-sill contacting member, a roof-engaging snow-removing member pivoted thereto and extending upwardly therefrom, a

7 Number hand'lever having one end pivoted to the inner end of said horizontal member, and a connecting .rodsubstantially parallel to said horizontal memberand having oneend pivoted to said ihand leverat a point spaced from the horizontal member pivot, and the opposite end adjustably and pivota lly" clamped to said snow-removingo memher, at a point spaced .from its lowermost end, whereby relative rocking movement .of the hand lever on its pivot at theinner end of the "horizontal member will actuatethe snow-removingmember. i-
