SNOW-GUARD AND SLATE-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 618,134, dated January 24, 1899. Application filed December 16, 1897. Serial No. 662,229- (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM T. RUSSELL, residing at "Wellesley, in the county of Norfolk and State of Massachusetts, have invented Improvements in Snow-Guards and Slate- Fasteners, of which the following is a specification.

The invent-ion relates generally to improvements in roots, and more particularly to a device adapted for use in securing slates upon roofs.

The object is to combine a wind-guard,snowguard, slate-holder, and antirattler in a single device possessing advantages in point of simplicity, durability, inexpensiveness, and general efficiency.

The novelty of the invention lies in the terminal spring-loops of the fastening which serve as an antirattling slate-holder and a snow-guard.

The accompanying drawings illustrate one embodiment of the invention, both separately and applied.

Figure 1 is a View of a roof in course of con struction, showing the manner of using the device; and Fig. 2 is an enlarged view in perspective of the device.

Like numerals indicate corresponding parts.

1 represents the fastening device proper, formed of a single piece of spring-wire, the same comprising a shank 2, one end, 3, of which is pointed and bent downward for engagement with the framing of the roof. The opposite end is bent upward and then extended parallel with the shank for a distance sufficient to form a spring-loop 4, designed to serve as a slate-retaining hook.

5 represents a loop spring formed by a con tinuation of the hook a and terminating adjacent the latter at a point where the entire force or pressure thereof will be exerted upon the slate confined by the hook. This spring is inclined more or less to render it mosteffective in sustaining the weight of the snow and to prevent its sliding.

Referring to Fig. 1, it will be seen that by the use of this fastening each slate is held at four points and under thefconstant tension of the spring snow-guards; also, that by reason of the large number of guards employed and their even distribution over the roof snow will be held evenly and banking or sliding rendered improbable, if not impossible.

Having thus described my invention, what I claim is- A combined snow-guard and slate-fastener formed of a single piece of wire having attaching means at one end and bent upon itself, adjacent to the opposite end to provide a slateretaining hook and thence carried around into a loop-spring guard having a free end in advance of the open end of the hook, the loop being sufficiently expanded to bring such free end to bear yieldingly against the upper sur face of the slate, for the purpose specified.

In testimony whereof I affix my signature in the presence of two witnesses.

WILLIAM T. RUSSELL. lVitnesses:
