stares Y SNOW GUARD.

vapplication fired May 11, 1923. yseran No. 638,269.

T o all whom it 'may concern Beit known that I, ALBERT W. CAMPBELL, a citizen of the United States, residing at Hartford, in the county or" Hartford and State of Connecticut, have invented a new and useful Improvement in Snow Guards, of which the following is a specification.

This invention relates to those articles which are designedto be applied to the roofs of houses and other buildings that are covered with slate, tile or shingles, for the purpose of breaking up snow and ice and preventing such from sliding off in heavy masses and causing damage.

The object of the invention is to provide a strong durable,'cheap and attractive articlek of this nature that can be quickly placed and firmly held in position on roofs beneath slate or shingles, which article is formed to shape without the use of rivets or the aid of solder.

This object is attained by bending and folding together pieces cut or stamped from sheet metal, desirably copper, in such manner that when assembled the article may 'be easily slid under over-lying sections of slate and hooked over the edge of underlying sections of slate, with the guard portion projecting outwardly in the usual manner between the slate in position to retain snow and ice.

In the accompanying drawings Fig. 1 shows a plan of an article constructed according to the invention. Fig. 2 is a side view of the same. Fig. 3 is a 'bottom view. Fig. et is an end view. Fig. 5 is a section on the plane indicated by the dotted line 5 5 on Fig. 1. v

The base 1 of the guard is a stripcut from sheet metal, desirably copper, with one end slightly reduced in width to provide shoulders 2, and the other end forked to form fingers 3. The stock between the fingers is bent under the base to form a hook 4.

The upright member of the guard, the active section 5 of which may have any suitable cross sectional shape but which is preterably a rectangular tube as illustrated, is formed from a single strip of sheet metal, preferably copper,`bent to shape. After forming the tubular section ofthe upright member the sides of the strip are brought togetherto form supporting legs 6, then bent outward to provide feet designed to rest upon the narrowed section of the base strip, and then the ends '8 are bent around under the narrowed section of the base so as to clamp the parts together. The shoulders 2 prevent the upright member from sliding up on the 'base strip and fingers 9 at the ends of the base strip are bent over the edges of the feet 7 so as to prevent the upright member from slipping down ofi' from the base strip. In order to .stiften the upright member a brace piece 10 is arranged to stand upright across the diagonal diameter of the tubular part, which brace may ,have its lower edge bent outward to extend under one of the feet 7.

With this constructionthe parts are interlocked so that the upright member is rmly secured to the base member without the use of any rivets, bolts or screws and without the aid of any solder or brazing. It is a simple matter to cut the strips and fold them together in the manner described. The article constructed in this way is light yet is very rigid and strong. ln order to put the article in position for use the fin ers at the upper end of the base are mere y slipped under the edges of the overlying slate. It is not necessary to pry up the edges of the slate for the fingersl are thin and readily slip under them. Then the base strip is pushed up until the hooked end under the {inge-rs snaps over the edges of the underlying slate. When the article is located in this manner it cannot be ,dislodged so as to slide down, and the edges of the slate eX- tending on each side of the legs of the upright section hold that end down and support it in such. manner that it will not be bent sidewise in either direction when it is subjected to the pressure of snow and ice that it is holding.

The invention claimed is 1. A snow guard comprising a base strip having at one end means for retaining the article in place, and having at the other end an upwardly extending tubular section formed of a strip of sheet metal, the ends of which are bent around and interloclred with the base section.

2. A snow guard comprising a base strip and an upright member, said upright member being formed of a strip of sheet metal with a tubular section, sections extending from the tubular section and bent around the base strip, and sections of the basey strip bent over the sections of the upright sections that are bent around the base strip.
