D. LEVOW SNOW GUARD I May 11,1937.
Filed June 27, 1935 INVENTOR.
ATTORNEY Patented May 11 193'? D STATES Application .iune 27,
This invention relates to improvements in snowguards, being particularly directed to a construction thereof as applied to roofs of small dwellings.
Up to the present time, snowguards have been applied mainly to slate roofs of large buildings of the institutional type, and in such structures the base of the snowguard essentially was of the shape and size of an individual slate taking the place thereof in the roof assembly. With respect to installation of a snowguard upon already completed roofs, considerable difiiculty has been entailed due to the necessity of removal of slates in order to insert the snowguard of the aforementioned type. With respect to roofs of small private dwellings, it has been impossible to apply snowguards, mainly because of their size and weight, also because of their expense. To obviate these difiiculties, I have provided a simple constructional formation of a snowguard capable of application to small dwellings and having a base formation and adjustable guard assembly, whereby the same may be applied to the roofs of small dwellings, whether upon old roofs or new constructions.
Broadly, it is an object of this invention to provide for a snowguard construction, wherein the base thereof has one portion resting on a slate or shingle and the remaining length thereof is readily slidable under a plurality of slates or shingles in the adjacent banks or rows of slates or shingles, the base extension being provided with apertures for nailing the same to the roof, such apertures being so located and spaced as to permit fastening thereof all along its length.
Specifically, it is an object of this invention to provide for a snowguard construction wherein the base thereof is formed of material of a thickness not greater than one-half the thickness of slates or shingles and normally of not greater than one-half the width thereof, whereby to minimize spacing between the slate or shingle and roof and at the same time eliminate the tendency of the slates or shingles to crack.
These and other advantages, capabilities and features of the invention will appear from the subjoined detailed description of one specific embodiment thereof illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the device.
Figure 2 is a perspective view of the device.
Figure 3 is a side elevation of a modified form of the device.
Referring to the reference characters in the drawing, there is shown a snowguard unit com- 1935, Serial No. 28,623
prised of a T-shaped cast metal bracket l0 having an upstanding body portion H and integral arms I? forming a fiat base. Ihe body portion is U shaped having upstanding ears l3 and I 4 in which ears there are formed apertures i5 and 16 respectively. Associated with ear i3 is one end of an adjustable carrier bracket I! having an eye 58a disposed adjacent the aperture l5 of the body portion N, there being adapted to be passed through the aperture of the body and the eye of the carrier bracket pipe P forming one of the guard bars of the device, the carrier bracket being permitted by such formation to be angularly displaced with respect to ear 13 of the body portion II.
There is associated with the ear M of the body portion an adjustable latch element 19, the same having an eye 20a. disposed adjacent the aperture of the ear I4, whereby the latch may, at such point, be mounted to the ear [4 by means of nut and bolt assembly 2 I. The latch has several apertures 20b, 20c, and 20d therein which are adapted to be associated with aperture Zla intermediate of the carrier bar, so that a bolt and nut assembly 22 passing through the aperture of the carrier bar and one of the apertures of the latch will serve to determine the angular position of the support bar with respect to the bracket. At the free end of the carrier bar is formed an eye I8b through which is adapted to pass a pipe or guide rod P; the respective pipes or guide rods P and P serving to maintain snow properly on the roof.
As shown in Figure 3, the latch bar indicated in the preferred form of the invention, is eliminated and the support bracket is a T-shaped casting having a body portion of V-notch configuration. An aperture |5a is provided to cooperate with the eye l8 of the carrier bar, whereby pipe P may be passed therethrough. Centrally of the carrier bar is formed an elongated slot 23 through which passes a bolt 24 of a bolt and nut assembly; on the support bracket adjacent the apex thereof and to one side are formed a series of spaced apertures 20', so that the bolt 24 disposed in the slot 23 of the carrier bar, when passed through one of such slots, will form a firm two-point support for the carrier bar on the support bracket. The free end of the carrier bar has an aperture I8" therein, through which passes pipe PI for the purpose above described.
The support bracket $5 is riveted as at 25' to elongated base 25, the portion 26 of the base directly attached to the arms I2 and !2 of the support bracket being provided with a cushion element 26, formed of a strip of lead or like material in a manner and for the purpose as described in applicants Patent No. 1,925,263, September 5, 1933. The elongated base is of a width no more than one-half of the slate or shingle upon which it is carried and is of a thickness of not more than one-half the thickness of the slate or shingle, so as to minimize the spacing of the slate or shingle under which the base is carried with respect to the roof and at the same time to eliminate the tendency of the slate or shingle to crack or break.
As will be noted, the base 25 carries a support bracket I9 at one end 26, but is sufficiently long as to extend for at least a plurality of rows of shingles or slates, the elongated portion 21 of the relatively thin base having provided therein separate series of spaced apertures 28 and 29, the portion of the base carrying the support bracket being adapted to rest directly on one slate or shingle, the elongated portion of the base being adapted in the construction of new roofs, to rest under the next succeeding banks or rows of slates or shingles, the base being fastened to the roof by passing nails through the aperture series 28 or 25 thereof and the adjacent banks or rows of slates or shingles being disposed thereover.
With respect to an old roof upon which the snowguard is adapted to be applied, a series of snowguards with the pipes P and P removed are disposed on the edge row of slates or shingles, and the elongated part of the bases thereof passed under the next succeeding banks or rows of slates or shingles, the snowguard being placed so that some of the apertures in the elongated portion of its base are in line with the joint between shingles or slates of the adjacent banks or rows of shingles or slates, thus permitting the base to be nailed to the roof support upon which the slates or shingles rest. In order to prevent leakage, particularly where the elongation of the base of the snowguard passes under and between slates or shingles, a bibb 30, shown in dotted lines in Figure 2, is inserted under the slate joint above the base, thus to prevent water leakage.
It is obvious that various changes and modifications may be made to the details of construc tion Without departing from the general spirit of the invention as set forth in the appended claims.
1. In a snowguard, a base disposed on a shingle or slate, a support carried thereon, a bracket apertured at one end, a guard bar passing through said bracket aperture and said support to form a pivot for the bracket on said support, an aperture at the free end of said bracket for carrying a second guard, a longitudinal slot intermediate of the ends of said bracket, a plurality of spaced apertures at varying levels formed on each support and means passing through the longitudinal slot of said bracket and one of the apertures on said support for disposing the bracket at varying angles with respect to said support.
2. In a snowguard assembly, a base disposed on a shingle or slate, said base being of relatively thin material and narrow width, a support carried thereon, a bracket apertured at one end, a guard bar passing through said bracket aperture and said support to form a pivot for the bracket on said support, an aperture at the free end of said bracket for carrying a second guard, a longitudinal slot intermediate of the ends of said bracket, a plurality of spaced apertures at varying levels formed on each support and means passing through the longitudinal slot of said bracket and one of the apertures on said support for disposing the bracket at varying angles with respect to said support, and an integral elongation of said base disposed under the adjacent banks of shingles and slates for firmly supporting the snowguard with respect to the roof.
