Patented 22 BYRON A. HUDSON, OF WOONSOCKET, RHODE ISLAND SNOW GUARD Application. filed June 20,

This invention relates to an improved construction of snow guard to be applied to the roofs of buildings to prevent excessive quantities of snow from sliding from the roof of the building.

The object of the invention is to provide a snow guard of this character which comprises an elongated shank member arranged to extend under the shingles at the point where it is fastened, the lower end of the shank being provided with an enlarged body member formed of a separate piece of sheet material rolled into conical shape and having bendable portions arranged to extend through an opening in the shank and be clinched on the under side thereof.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully de scribed, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a top view illustrating my improved form of snow guard as attached to a a5 shingled roof.

Figure 2 is a side elevation partly in section showing the snow guard as attached to the roof with a portion extending beneath the shingles.

Figure 3 is a detail view of the shank member of the guard with its body portion removed.

Figure 4 shows a blank from which the body portion is formed.

Figure 5 shows the body portion as attached to the lower end of the shank member.

Figure 6 is an end View showing the shank in section and showing the bendable edge portions of the body as extending through an opening in the shank and clinched against the under side of the shank.

Figure 7 is a View showing the upper portion of the shank member with a hook-shaped slot formed adjacent its upper end, the upper end of the hook slot extending longitudinally of the shank to better prevent the shank from becoming unhooked from the fastening nail it engages.

It is found in the practical use of snow guards for roofs of buildings of advan 1828. Serial No. 286,981.

tage to provide a thin metal shank member preferably of copper and of a length sufficient to extend a substantial distance up under the shingles on the roof and to provide the shank with openings through which the shingle fastening nails may be passed to secure the guard in position. Also it is found of advantage to provide in such a guard a body member formed of a separate piece of sheet stock which i ay be rolled into substantially frustro-conical shape with edge extending bendable portions arranged to project through a slot in the lower end of the shank and bent or clinched back upon the under side of the shank to securely lock the body to the shank, the smaller end of the cone being open to permit the passage of rain water but prevent the snow from passing through and so serve as an effective guard to prevent the large portions of snow from sliding from the roof during a melting period and prevent injury to persons and surrounding property on which the snow may fall; and the following is a detailed description of the present embodiment of my invention and showing one means by which these advantageous results may be accomplished.

With reference to the drawings, 10 designates the shank of the snow guard which is preferably formed of a thin strip of copper of sufficient length to extend a substantial distance under the shingles of the roof. This shank is preferably provided at one end with a hole 11 through which the shingle fastening nail 12 may extend; also I provide an elongated slot 13 extending longitudinally of the shank through which the second fastening nail 14k may extend, the elongated slot permitting the use of the shank with the nail 14 of different sizes of shingles. Also in some instances, I prefer to form a slot 15 in the edge 16 of the shank. This slot being in hook shape and having its inner portion 17 extending upwardly longitudinally of the shank so that it may permit the snow guard to be attached to houses already shingled in which case the shank is passed up beneath the shingles and this hook-shaped edge is caused to engage one of the fastening nails to secure the rd in position.

It is found that by having this upwardly cut at the end of the hook that the shank is less likely to become disengaged from the fastening nail.

At the lower end of this shank member I form an elongated slot 18 and I provide a body portion 19 for the shank member which is preferably formed of sheet stock into a blank 20 as best illustrated in Figure l having extending bendable edge portions 21 adapted, when the blank is rolled into frustroconical shape to extend through. the slot 18 and be bent or folded laterally back against the under side of the shank serving the double purpose of retaining the conical member in its desired form and at the same time fastening the conical member to the shank, the lower portion of this frustro-conical body member being open at its lower end as at 22 to permit rain water and melted snow to pass freely therethrough and by being larger at its upper end this body member serves to effectually engage the snow and prevent the same from sliding from the roof in large quantities.

My improved snow guard is very simple and inexpensive to construct and is effective in its operation and may be readily attached to a roof either while the shingles are being laid or to a roof on which the shingles have already been laid.

The foregoing description is directed sole- 1 towards the construction illustrated, but

desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A snow guard comprising an elongated shank member to extend beneath the shingles and having openings through which the shingle fastenings may extend, a hollow body member formed of sheet stock rolled into tapering shape open at its small end and having bendable extensions on its opposite edges of a length less than that of said body to extend through an opening in the shank and clinched on its under side to secure the body to the shank.

2. A snow guard comprising an elongated shank member formed of sheet stock having a hook shaped nail-receiving opening on one edge and a longitudinally disposed elongated fastening receiving slot along its mid-section,

a bodymember formed of sheet stock formed into frustro-conieal shape upon its smaller or lower end and having bendable edge portions arranged to extend through a slot in said shank and be clinched back against the under side thereof to secure the body of the shank.

3. A snow guard comprising an elongated shank member formed of sheet stock having an upwardly inclined slotin one edge, the upper end of the slot extending longitudi- BYRON A. HUDSON.
