SNOW-GUARD.

Application filed. December 10, 1915.

To all whom it may concern:

Be it known that I, EDWARD E. HIs'rAND, a citizen of the United States, residing at Doylestown, in the county of Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Snow- Guards, of which the following is a specification.

This invention contemplates an improved snow-guard and has as its primary object to provide a device of this character which may be readily attached to any conventional type of roof for preventing snow or ice from slipping from the roof in large cakes or blocks.

The invention has as a further object to provide a device of this character having an upstanding snow-stop or foot and wherein the said foot will be rigidly supported in upstanding position relative to the roof.

And a still further object of the invention is to provide a device of this character which will be simple in construction and may thus be cheaply produced, and which may be -formed from a blank capable of being struck by one operation from a single piece of material.

Other and incidental ob ects will appear as the description proceeds and in the drawings wherein I have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is an elevation showing my improved device in operative position upon a conventional type of roof.

Fig. 2 is a perspective view showing the device attached and more particularly showing the arrangement of the supporting arm for the upstanting snow stop or foot of the device.

Fig. 3 is a plan view more particularly illustrating the arrangement of the lugs for connecting the bearing portion of the device to its attaching shank.

attaching shank of the guard is provided with spurs for engagement with the root.

In carrying out the invention, my improved snow guard is preferably formed from a blank as illustrated in Fig. a, this blank being of such character that it may be struck by one operation from a single piece of material. The blank which is preferably formed of suitable resilient sheet metal, is provided, at one extremity, with an attaching shank 10 at the inner extremity of which, the body of the blank is laterally enlarged to provide a foot portion 11 having its outer end edges 12 beveled toward the shank. From the foot portion 11, the body of the blank is continued to form a supporting arm portion 13 equal in width to the portion 11, and is then slightly reduced to form a bearing portion 14 at the extremity of the blank opposite the shank 10.

Formed in opposite sides of the blank adjacent the free extremity of the bearing portion 14% are suitable oppositely disposed notches and from the inner extremities of said notches, opposite margins of the adj acent terminal of the blank are bent upon longitudinally extending parallel told lines to provide side flaps or lugs 15. At the intersection of the portions 11 and 13, the body of the blank is provided with oppositely disposed V-shaped notches 16 which open through the opposite edge of the blank and similarly disposed notches 17 are pro vided upon opposite sides of the blank at the intersection of the portion 13 with the portion 14 thereof. The side margins of the portion 13 are bent upon longitudinally disposed parallel fold lines each extending between the inner extremities of corresponding notches 16 and 17 upon one side of the blank to provide oppositely disposed flanges 18, each provided, at opposite ends thereof with beveled edges or shoulders 19 and 20 respectively.

The blank thus formed is first bent transversely at the inner extremity of the attaching shank 10 upon a fold line extending between the points of intersection of the beveled edges 12 of the foot portion 11 of the blank with the side edges of the shank,

to such position that the said foot portion will lie at right angles to the shank 10 to project upwardly therefrom as more particularly shown in Fig. 2. The supporting arm portion 13 of the blank at the point of its intersection with the foot portion 11 is then bent upona transversely extending fold line connecting the inner extremities of the notches 16 to occupy a position at an acute angle to the said foot portion, the said portion 13 providing an arm extending from the free extremity of the foot 11 obliquely away from the outer side thereof. The portion 14 of the blank at the point of its intersection with the portion 13 is then bent upon a transversely extending fold line connecting the inner extremities of the notches 17 toward the inner extremity of the shank 10 to occupy a position at an acute angle to the arm 13, with the free extremity of the portion 14 seating against the lower face of the shank at its inner end. The portion 14 is thus arranged substantially in alinement with the shank 10 to provide the bearing portion of the guard and the lugs 15 are then bent about opposite side edges of the shank to embrace the shank at its inner ex tremity with the lower edges of the said lugs engaging the foot 11 to support the bearing portion longitudinally. 7

From the preceding description and upon an inspection of Fig. 2 of the drawings, it will be observed that the foot 11, the arm 13, and the bearing portion 14 are arranged in triangular relation, the foot being arranged to project laterally and upwardly from the shank 10, the bearing portion projecting longitudinally from the inner extremity of the shank and the arm extending between and connecting the free extremity of the foot with the free extremity of the body portion. To reinforce the arm 13, the flanges 18 thereof are bent inwardly to occupy a position at substantially right angles to the body of the arm with the shoulders 19 of the said flanges engaging beneath the foot 11 and with the shoulders 20 engaging the adjacent inner face of the bearing portion 14. These flanges therefore serve a dual purpose in that they not onlyg act to reinforce the arm 13 but also, through the medium of the shoulders 19 and 20 thereof, provide additional bracing elements between the free extremity of the foot and the outer end of the bearing portion of the guard. A rigid structure is thus provided since the foot 11 will be firmly held in upright position by the arm 13 and flanges 18 while the lugs 15 will act to prevent any movement of the bearing portion 14 longitudinally away from the shank 10.

In Fig. 1 of the drawings, I have shown my improved guard in connection with a conventional type of shingle roof 21. The

free extremity of the shank 10 is inserted beneath one of the shingles and moved upwardly thereunder to a position with the foot 11 abutting the outer end of the shingle. If desired, the free end of the shank 10 of the guard may be provided with a plurality of openings as shown in the drawing, through which suitable fastening devices driven through the shingle may be inserted for connecting the guard to the roof. The guard will thus be supported with the foot 11 projecting upwardly from the roof, and with the shank 10 and bearing portion 14 seating flatly against the roof, the bearing portion 14 being then adapted to receive and support any strain communicated thereto through the arm 13 by downward pressure upon the foot 11, caused by cakes of ice or snow sliding down upon the roof, it, of course, being understood that any desired number of guards may be employed and arranged at suitable spaced points upon the roof surface. In this connection, it will also be understood that the dimensions of the guard may be changed to'suit varying requirements and it will be noted that the guard is of such nature that it may, without difiiculty, be applied to substantially any type of roof. 4

In Fig. 5 of the drawings, I have disclosed a slight modification wherein the shank 10 of the guard adjacent its free extremity, is provided with longitudinally spaced reversely arranged spurs 22. These spurs are substantially V-shaped and are preferably struck from the shank with their pointed ends projected downwardly to engage a roof and are so arranged that their flat sides will be presented to the grain of a wooden shingle to prevent splitting thereof.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A device of the character described formed from a strip provided with an attaching shank and having longitudinally spaced pairs of oppositely disposed notches formed in the margins thereof to define a foot upstanding from the shank, a bearing member extending longitudinally of the shank and provided with attaching lugs engaging the said shank, and a flanged supporting arm extending between the foot and bearing member with the flanges of the said arm engaging the confronting faces of the foot and bearing member to cooperate with the arm in supporting the foot in position.

2. A device of the character described including a body formed with an attaching shank and having portions of its length arranged to' provide one a foot upstanding from the shank, another a bearing member extending longitudinally of the shank, and the other a supporting arm for the foot extending between the foot and bearing member and of less width than the foot, and reinforeing flanges carried by the said arm and having their ends formed to provide 5 shoulders conforming to the adjacent faces of the foot and bearing member and engaging therewith in inward spaced relation to the side edges of the said foot and bearing member to cooperate with the said arm in supporting the foot relative to the bearing member.

In testimony whereof, I affix my signature.

EDWARD E. I-IISTAND.
