SNOW-GUARD.

SPECIFICATION forming part of Letters Patent No. 752,216, dated February 16, 1904.

Application filed June 6, 1902. Serial No. 110,483. (No model.)

To a ZZ whom it may concern:

Be it known that I, Gnonon F. FoLsoM, a citizen of the United States, residing at Roslindale, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Snow-Guards, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawing representing like parts.

My invention has for its object to provide an improved snow-guard.

Prior to my invention, so far as I am aware,

' wire snow-guards usually have been supported solely at the base next the roof, the strength and stiffness of the wire at that point being alone relied upon to prevent the outwardlyprojecting weight-sustaining or stop portion from bending or flattening down.

My invention aims to improve and strengthen snow-guards of this type by supporting the outwardly-projecting or stop portion at a point above the base thereof and preferably at or near its top, thereby the better to sustain its load.

My invention will best be understood from a description of a guard illustrating one embodiment thereof.

In the accompanying drawings, Figure 1 in perspective shows a snow-guard illustrating my invention as it will appear when in position upon a roof; Fig. 2, a side elevation of the guard shown in Fig. 1; and Fig. 3, aview looking from the right, Fig. 1.

In the particular embodiment of my invention selected for illustration herein and shown in the drawings, a is the usual shank, adapted to lie between adjacent slates or shingles and provided at its upper end with the usual spur a, adapted to be driven into the roof-boards. At its lower or supporting end the shank a is bent outward, preferably upon a gradual incline, as at (f, and its end is then turned to one side at an angle and given a preferably circular sweep a to'constitute the snow-stop, which receives and sustains the weight of the snow above it. At the point where the outwardly-inclined portion a? is turned abruptly to form the sweep or snow-stop of there is formed a slight offset of, behind which the free end a? of the wire is carried for support. The snow-stop a is thus supported at or near its top or at the point where the pressure of the snow upon it is the greatest, so that there is practically no liability of the Weightof the snow bending or flattening down the stop, as frequently occurs when the stop is supported at its base only. Furthermore, the outwardlyinclined shank portion a serves as a deflector to deflect outwardly and clear of the stop any piece of wood or other object sliding down the roof and which might otherwise lodge behind or flatten down the stop. From the base of the deflecting incline a to the spur a the shank is held down by the slate or shingle resting upon it, as indicated in the drawings.

My invention is not restricted to the embodiment thereof hereshown and described, but may be varied Without departing from the spirit and scope of the invention.

I claim a I 1.. A wire snow-guard comprising a snowstop and a supporting-shank therefor connected thereto at a point above its base.

2. A wire snow-guard comprising a snowstop and a supporting shank therefor connected thereto at or near the top thereof.

3. A snow-guard comprising a snow-stop and a wire supporting-shank therefor connected thereto at a point above the base thereof.

4:. A snow-guard having an individual snowstop provided at its upper side with a substantially centrally located deflector.

5. -A snow-guard comprising a snow-stop and a supporting-shank therefor connected thereto at a point above its base, the whole formed from a single piece of wire.

6. A Wire snow-guard comprising a shank having a spur at one end and at its opposite end bent outwardly and then inwardlyto form a snow-stop supported at or near its top.

7. A wire snow-guard comprising a shank bent outwardly at its lower end and then inwardly to form a snow-stop, the free end of saidwire being carried for support behind an intermediate portion thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE F. FOLSOM.
