EMRI' IV. CLARK, OF NASI-IUA, NEW HAMPSHIRE.

SNOW-GUARD.

SPECIFICATION forming part of Letters Patent No. 625,144, dated May '16, 1899.

Application filed December 24,1898. Serial No. 700,196. (No model.)

To all whom it may concern.

Be it known that I, EMRI W. CLARK, a citi= zen of the United States, residing at Nashua, in the county of I-Iillsborough and State of New Hampshire, have invented a new and usefulImprovement in Snow-Guards,of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is top plan view of a part of a roof, showing my new snow-guard in place. Fig. 2 is a section on the line a; w of Fig. 1. Fig. 3 is a perspective view of my new snowguard. Fig. 4: shows a modification in perspective.

The object of my invention is to provide a snow-guard which can be put in place on any shingled or slated roof, new or old, and of any pitch and with any length of the covering exposed to the weather.

My invention consists in the snow-guard hereinafter described and claimed.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, A is the body portion, one end of which is bent to form a hook A. The other end of the body portion A is notched by bending up a portion A at right angles to the body portion A. To the part A is riveted a triangular-shaped brace 13, from each side of which projects the triangular-shaped wings B B;

I do not wish to be understood as limiting myself to the particular construction, for the snow-guard may be made in a single piece and the parts may be of a different shape, either cast or struck up, from that described without departing from the principle of my invention.

In the modification shown in Fig. 4 a second pair of wings D D project from the lower outer end of the triangular-shaped brace B In fitting my snow-guard to newroofs the body portion A is secured in place by the hook A hooking over the upper end of the shingle For slate, the vertical portion A being placed between the shingles or slates F F of the row next above, In fitting my snow-guard to old roofs the body portion A, which is very thin, is inserted under the shingles (or slates) F F, over the shingle E, and

Second. The sidewise-projecting wings bear at their lower edges on the shingles between which the vertical portion A lies. These wings prevent cooking or twisting of the snow-guard about its longitudinal axis, and thereby keep the guard in an operative po= sition.

Third. The piece B acts as a brace to stiffen the construction as well as to act as a point of support for the wings.

Fourth. The flat body portion has a more extended bearing than any snow guard known to me. This extended bearing distributes the pressure of the snow and ice over a larger area and therebyavoids the cracking of the slate upon which the guard rests. Moreover, the thinness of this fiat body portion permits its easy and ready insertion under slates already laid, as in old roofs, as well as under slates which are being newly laid, as in new roofs. An especial advantage lies in the entire absence of strain when the body portion is inserted underneath it, and this absence of strain is due to the thinness and flatness of the body portion. In the forms heretofore used the thickness of the body portion greatly strained the slate and the width of the slate afforded much leverage. The result was that the plate was fractured by the shingles F F, and thereby hold the shingles F F down against the upward pressure of the I11 testimony whereof I have signed this IO body portion A. 1 specification, in the presence of two subscrib- What I claim is ing witnesses, on this 22d day of December, As a new article of manufacture, a snow- A.
