SNOW GUARD.

Application filed April 24, 1924. Serial No. 708,627.

To all whom, it may concern:

Be it known that I, GEORGE E. Ginsnn, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and

State of Pennsylvania, have invented a new and useful Improvement in Snow Guards, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improved construction for snow guards, such as are applied to the roofs of buildings to hold snow and ice and prevent masses thereof from sliding off and causing injury to persons passing.

Heretofore snow guards have been made by casting, and such have proved sufficiently satisfactory, except for the fact that these are of substantial weight and relatively expensive to produce.

Now it is the object of my invention to provide a snow guard so constructed as to have a maximum of efliciency and durability, and at the same time be capable of.

production at a relatively low cost.

More particularly my invention has for its object the production of a snow guard from a single piece of material so formed as to cause the various parts of the guard to cooperate in action, or as it were cooperate one with the other in resistance to the weight of snow, and ice, whenever the guard may be called upon to resist, thus not only enabling the use of relatively light material and a minimum thereof, but simplifying the labor of production, with resultant economy in production without sacrifice of efliciency and durability.

Having now indicated in a general way the nature, purpose and advantage of my invention, I will proceed to a detailed description thereof, with reference to the accompanying drawings, in which I have illustrated a preferred embodiment of my invention, and in which:

Figure l is a side elevation of a device embodying my invention.

Figure 2 is a plan view of the device illustrated in Figure 1.

Figure 3 is a sectional view on line 3-3 Fig. l.

The device as illustrated and in accordance with my invention is formed from a single length of material, for example strap iron.

form a base member a, adapted to rest on a row of shingles on a roof and be partially extended beneath the next row above. The base is provided with holes 6, b, for the passage of securing devices, as nails.

The base is mad of desirable length and at one end the material is bent back at an acute angle, as at 0, Figure 1, and extended to form a brace number d. At the upper limit of the brace the material is, folded under itself at right angles, as at e, and extended to form a stop number 7, which preferably is generally circular, as shown in the several figures, but which may be of any convenient shape.

Tn forming the stop member f, the ma terial is so extended as to contact with the base number a at a point beneath the upper limit of the brace number, and is secured thereto by means of a rivet g, as will be understood from an inspection of Figures 1 and 3.

In operation, a plurality of snow guards in accordance with my invention are secured to the roof of a building as above indicated. The stop members of the several guards extend in the path of any snow and ice tending to slide off the roof and prevent it.

When pressure is put on the stop, such pressure is transmitted to the base member in one direction through the brace member, and oppositely through th rivet connection between thestop and base member. Thus the pressure on the stop is balanced in the The material is extended in a plane to base and the stop, brace and base act, as it I were, as a truss.

Thus, by virtue of my invention there is provided a guard so formed from a single strip of material that pressure of ice and snow on the stop member of the guard is efliciently resisted without anytendency for the guard to be turned over or the base 7 to be pulled away from the roof, without strain 011 the means securing the guard to the roof and without the necessity for the use of more than a minimum of weight of material in the construction.

Having now fully described my invention, What I claim and desire to protect by Letters Patent is:

1. A snowguardiformedsfromca single length of material'bent to extend in one direction to form a base, at an acute angle .to the sbase tozfiorm -a brace, and at right angles to thewbraceito form a stop.

2. A snow guard formed from a single length of material bent to eXtendiinv-one direction to form a base, at an acute angle to the base to form a brace, =and-at right angles to the brace to form a stop and means to secure" the stop to the base.

3. A snow guard comprising .a base member, a stop member secured to the base,-:and a brace member extended between saidi-base member, and said stop, all of said members being formed from a single length of material.

A. A1sno\v=,;guard formed from a single length'of material bent to extend in one direction to form a base, at an acute angle tothe base'to form Ia brace, and at right angles and in. a circle contacting with the base to form a stop, and means to secure the stop to the base at a point in its cireumference su bstantially opposite to the brace 011 this2lst day of April, 1924.
