GEORGE F. FOLSOM, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HENRY M. ESSELEN, MANAGER, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 602,983, dated April 26, 1898.
Application filed $eptember 20, 1895. Serial No. 563,138. (No model.)
To all whom it may concern:
Be it known that I, GEORGE F. FoLsoM, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement-in Snow-Guards, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
My invention relates to snow-guards, and has for its object the production of a guard capable of direct attachment to individual roof-tiles, and in particular to tiles of the interlocking type whose complicated configuration and close joints render impracticable the use of the common form of guard having an extended straight shank to lie between the tiles and usually having an attaching portion to be driven into the roof proper.
The various features of my invention will be fully illustrated and described in the accompanying drawings and specification, and set forth in the claims.
Figure 1 is a view in front elevation of the preferred form of my improved snow-guard. Fig. 2 shows in perspective a number of tiles in place upon a roof with several of my improved guards attached. Figs. 3 and 4. are views in front elevation of modified forms of attachable guard, Figs. 3 and 4 being, respectively, side elevations of the same; and Fig. 5 is a sectional view of two adjacent tiles, showing manner of attaching the modified form of guard, the view being taken on a line corresponding to a: m, Fig. 2.
M yimproved snow-guard is preferably composed of a single piece of wire having at or near its middle a snow-stop loop a), formed by bending the wire upward and around, as at a a a the shanks a a of the wire being extended past one another in opposite directions to close the loop at its bottom. Near the ends of the shanks, as at a a, the wire is again bent to form the downwardly-extended offset or attaching portions a a lying in substantially the same plane with the loop.
In Fig. 2 the preferred form of my guard is shown as applied to a tile 1), of the heavy channeled type, provided with perforations or recesses d cl, into which, as sockets, the attaching portions a of the guard are adapted to enter and be snugly held therein.
Between these sockets, with one of which each of the outer ribs d d of the tile is provided, the guard extends bridge-like across the tile-channels 01 01 the loop a coming directly over the medial rib By this arrangement no obstruction is offered to the natural drainage of the roof through the channels (2 d parallel to the pitch thereof 5 but downward movement of any considerable accumulation of snow, ice, duo. in the channels is prevented .by the shanks a a, while the reinforced lower portion of the loop is specially fitted to withstand the force of ice cakes or other large bodies which naturally would slide upon the higher parts of the tile.
In the modification shown in Figs. 8 to 5 the loop of the snow-stop may be closed, as in Fig. 3, and formed in like manner to the construction already described and illustrated in Figs. 1 and 2, or the loop may be open, as shown in Fig. 4., with its upper portion preferably inclined forward for strength. Legs b b c 0 respectively correspond in the modified form to the attaching portions 0. of Fig. 1, but are longer and are provided with hook-like offsets or clamps Z1 c formed by bending the wire, substantially as at b or o first forward, then upward, as at b or c", in a plane perpendicular to the plane of the snow-stop proper, the portion intermediate being indicated in the respective figures by reference-letters b and 0 To attach this form of guard, no alteration in the structure of the tile is necessary, the attachment being efiected by approaching the tile to the guard, so that the downturned shoulders d of the overhang d of the tile register with the openings of the clamps 19 or 0 which latter are adapted to receive the said lips snugly. The said clamps of the guard are then drawn firmly into position (see Fig. 5) as far as they will go upon the shoulders d of the overhang 61 where the guard is held by the natural resiliency of the wire, which, however, is sufficiently rigid to enable the upwardly-projecting snow-stop Z2 to hold the snow, (he, in check.
By the term tile I mean the technical tilet'. a, one made of earthenware or similar tile materialand by the term shoulder I mean such portion of a tile as is adapted to be engaged by a guard and tohold the same independent of the roof or tile support.
I claim- 1. The combination with a snow-guard, of a roof-tile provided with a shoulder for engagement with and to hold said guard, the latter being arranged to engage said shoulder and be held thereby independent of the roof or tile support, substantially as described.
2. The combination with a roof-tile having a shoulder, of a snow-guard provided with a plurality of integral attaching-clamps adapted to embrace and be solely supported by said shoulder, and having an upright snow-stop portion to extend above the tile, substantially as described.
3. As an article of manufacture, a snowg-uard provided with a plurality of integral attaching-clamps adapted to embrace and be solely supported by the shoulder of a tile, and having an upright snow-stop portion to extend above the tile, substantially as described.
4. A snow-guard adapted to be directly attached to and rigidly supported by an individual roof-tile, without preparatory alteration in the contour of said tile, substantially as described.
5. Thecombination with a roof-tile of usual contour, of a snow-guard attached directly thereto and retained in place solely by superficial contact therewith, substantially as described,
6. The combination with a roof-tileha'ving a shoulder, of a snow-guard provided with an integral attaching-clamp adapted to embrace and be solely supported by superficial contact with said' shoulder, and having an upright snow-stop portion to extend above the tile, substantially as described.
7. The combination with a roof-tile having a shoulder, of a snow-guard provided with a plurality of integral attaching-clamps adapted to embrace and be solely supported by superficial contact with said shoulder, and having an upright snow-stop portion to extend above the tile, substantially as described.
8. The combination with a roof-tile having a'shoulder, of a snow-guard provided with resilient attaching means to receive and embrace said shoulder, substantially as described.
9. The combination with a roof -tile, of earthenware or other fragile material, of a snow-guard adapted to be positioned and retained in place on said tile without preparatory alteration in the contour of the latter, substantially as described.
10. A snow-guard for roofs composed of molded tiles; saidguard consisting of a snowstop portion adapted to extend above the roof, and an attaching portion adapted to enter the recessed portions in, or interstices between, said tiles, to engage and be supported by such salient portions of said tiles as the walls of said recesses or'in-terstices, substantially as described,
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
