ALBERT DANZER, OF HAGERSTOWN, MARYLAND, ASSIGNOR TO DANZER METAL WORKS, OF HAGERSTOWN, MARYLAND.
SNOW-GUARD FOR ROOFS.
To all whom it may concern Be it known that I, ALBERT DANZER, a citizen of the United States, and a resident of Hagerstown, in the county of lVashington and State of Maryland, have invented an Improvement in Snow-Guards for Roofs, of which the following is a specification.
My invention is a snow-guard constructed of plate metal and distinguished by strength, durability, lightness, cheapness, and facility of attachment to a roof. The details of construction of the same are as hereinafter described, and illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of the device applied to a corrugated, metal roof. Fig. 2 is a cross section of the guard on the line 2-2 of Fig. 1. Fig. 3 is a cross section of the guard and roof on the line 3-3 of Fig. 1.
The guard is formed of a single blank of rolled metal plate, preferably galvanized iron. It consists of a body A which is of ornamental form, and parallel portions in the nature of arms B, which are formed integrally with the body A and project from the lower edge thereof at an obtuse angle. A distinguishing feature of the guard is the form of these arms B and that portion of the body where they join the same. That is to say, the arms B are struck up in such manner that they have a central lengthwise corrugation or convex rib, the same also extending into the body A to a point 1) near the middle of the latter, as. shown in Fig. 1. By this means, the guard as a whole is greatly increased in rigidity, and the arms B being concave on the under side are adapted to fit on parallel ribs or corruga- Specification of Letters Patent.

tions of the roof X, as shown in Fig. 3. Another feature is the corrugation and upward curve indicated at C in Figs. 1 and 3, whereby the guard is further strengthened in the middle portion and due space is provided for the roof rib that intervenes the two ribs to which the arms B are secured. The attachment of the guard to the roof is effected by means of rivets b, or equivalent fastenings.
The guard is preferably used alone or without a wooden bar or board which is a common attachment of roofs. If, however, it be desired to use a bar or board, it may be readily secured to the upper side of the plate A by means of screws or other fastenings inserted through holes in the plate.
WVhat I claim is 1. The improved metallic roof-guard, consisting of an approximately fiat body having parallel arms projecting from its lower edge, the body and arms being formed integrally, and arranged at an obtuse angle to each other, the arms having concavo-conveX corrugations extending their entire length and also into the body of the guard, the ends of said body projecting laterally beyond the arms, as described.
2. The improved metallic roof-guard, consisting of a flat body constituting the guard proper, and integral arms projecting from the lower edge and arranged at an angle to the body and having lengthwise corrugations, the lower edge of the body between the arms being curved upward, as described.
