SNOW GUARD.

UNITED STATES.

PATENT OFFIC THOMAS O GARA, OF VORGESTER, MASSAOHUSETTSQ SNOW-GUARD.

SPECIFICATION forming part of Letters Patent NO. 450,251, dated April 14, 1891. Application filed December 13 1890- Serial No, 374,558. (No model.)

To all whom it may concern:

Be it known that I, THOMAS OGARA, a citizen of the United States, residing at \Vorcester, in the county of Vorcester and State of Massachusetts, haveinvented a new and useful Snow-Guard, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same. I

The object of my present invention is to provide an improved wire snow-guard that shall be simple, strong, and efficient, which will not when in use become twisted or forced around sidewise upon the roof, and which can be inexpensively manufactured and readily applied to use. I attain these objects by a wire snow-guard of the peculiar construction illustrated in the drawings, and explained in the following description.

In the drawings, Figure 1 is a section of roof, illustrating the manner of using my improved wire snow-guard. Fig. 2 is a perspective view of my improved wire snow-guard, showing the peculiar form and arrangement of bends in the wire to produce the article. Fig. 3 is a side View, Fig. 4: a top plan View, and Fig. 5 an end section, of the snow-guard, with dotted lines indicating the position of the slates or shingles in connection with which the guard is employed.

My improved guard is formed of a single piece of Wire, which is bent at its central part to form the snow-stop or arched loop 1, at the extremities of which the wire is bent inward at 2 and extends horizontally to a central position to form the transversely-disposed bottom bars 3. Then at the center or point of junction the wire is bent downward, as at 4, and the two bars are extended a distance equal to the thickness of the slate to form a neck or upright shoulder 5. Then the wires are bent backward at right angles, as at 6, and extended parallel to each other, forming two supporting-bars 7, at the extremities of which the ends are turned downward, as at 8, and each fitted with a point or claw 9, that can be driven into the roof, thus forming a complete, simple, and convenient guard of peculiar shape, having the neck 5 and double supporting-bars, the neck extending upward from the supporting-bars substantially at a right angle to the plane thereof and the snowstop projecting upward and disposed transversely to the two supporting-bars, as illustrated.

WVhen applied to use, the claw 9 is driven into the roof-board a above the'head of the slate b, and the bars 7 rest upon the top of the slate b. The slates c and d are then laid so that they will pass under the transverse bottom bar 3 and rest laterally against the shoulder 5 or side of the upright neck. A slight nick in the edges of said slates cand d, as per dotted lines at f, Fig. 4, allows space for the wire and permits the edges of said slates above and below to come together with a close joint and to cover the supportingbars 7, while the bottom bars 3 of the snow-stop rest upon and are supported by the top of slates c and d, the joint of the slates c and d, with the attaching-bars 7, being protected by the overlying slate e of the upper'course. The two supporting-bars 7, with their respective claws 9, give a secure hold for both ends of the snow-stop, so that the device is not liable to be twist-ed or straightened out by masses of ice wedging against them, While the shoulder or neck, being confined between the two overlying slates or shingles c and d, effectually prevents the forcing of the snowstop to one side. The bars 7 are also securely held down, since the two bars lie under the respective edges of the two adjacent slates and not in the center of the joint-opening, as

is the case when but a single bar is employed. I am aware that snow-guards made of Wire and having a point to drive into the roofhaving their ends turned downward and respectively fitted as a point or claw 9 to be driven into the roof-boarding, all substantially as and for the purpose set forth.

WVitness my hand this 9th day of Decent I her, A. D. 1890.

THOMAS OGARA.
