SAFEGUARD FOR WINDOW-GLASSES.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Application filed June 24, 1908. Serial No. 440,116.

To all whom it may concern:

Be it known that I, EDWIN B. BAvE, a citizen of the United States, and resident of Bayonne, in the county of Hudson and State" of New Jersey, have invented certain new and useful Improvements in Safeguards for "Window-Glass, of which the following is a specification. I

My invention relates to safeguards for large plates of glass, so that when such safeguard is applied aplate of glass cannot take up destructive vibrations but the same will be transmitted through a proper mechanism to a less fragile material.

In the drawings, Figure 1 is a perspective of a window frame provided with my improved safeguard; Fig. 2 is an enlarged side elevation of the foot, and Fi 3 is an enlarged section through one o the pressure arm brackets and its connections- In the drawings, 1 represents a window frame of usual construction and 2 is a pane of glass which it incloses. Brackets 3 are secured at suitable points on the frameby screws 4, or similar devices.

5 is a foot adapted to bear against the glass 2, and having an outwardly extendin post 6 provided with threaded apertures a apted to receive the ends of relatively slender bowed spring pressure arms 7 ,--7 one on each side, the direction of the tension of the spring members being inward, thereby forcing the foot 5 against the glass. When the foot 5 is forced against the tension of arms 7, the bow on each side of the foot tends to straighten and, during the straightening operation offers yielding resistance to the outward movement of the foot 5, which resistance is in lnverse proportion to the straightening of the curve of the arms.

These arms are secured at their outer endsz'.

to the brackets 3, to which they are secured by bolts 8, and on which they may be tightened by turn sleeves or turn buckles 9. It will beevident by the construction described the glass is yieldably held, and a single member 5 will serve by itselfto hold quite a large glass. The foot is placed in position, and the pressure arms are then tightened to bring a steady uniform pressure to bear on the glass. It is not desirable the foot should be movable, as it is liable-to accidental displacement, and it will readily be understood that the pressure should be such that it ought not to be readily movable.

In order to relieve the pressure arms 7 of the duty. of su porting the weight of the post 6 and its oot, I provide the post with corrugations 10 adapted to engage the hook ,11 of a rod or wire 12 suspended from one of the brackets 3. The hook can readily be adjusted to a place between any two corrugations.

What I claim as new is 1. A safeguard for glass, comprising a foot adapted to rest against the glass, a fixed bracket, and a slender spring "arm secured at one end to the foot 'and at the other end to the bracket, said arm being bowed.

2. A safeguard for glass, comprising a foot adapted to rest against the glass, a plurality of fixed brackets, and a plurality of slender spring arms secured at one end respectively to the foot, and at their other ends respectively to said brackets, said arms being bowed.

3. A safeguard for glass, comprising a foot adapted to rest against the glass, a fixed bracket, and a slender spring arm secured at one end to the foot and at the other end to the bracket, said arm being bowed, and a turn buckle connection between the end of the arm and the bracket.

Witness my hand this 22d day of June 1908, at New 'York N. Y.
