WINDOW-GUARD.

Specification of Letters Patent.

Patented Jan. 11,1916.

Application filed May 3, 1915. Serial No. 25,542.

To all whom it may concern:

Be it known that I, ABRAHAM BROUNE, a citizen of the United States, and resident of Brooklyn, New York, in the county of New York and State of New York, have invented new and useful Improvements in Window-Guards, of which the following is a specification.

This invention relates to improvements in safety devices and particularly to that class used in connection with window openings of dwellings, vehicles and like structures.

The objects of the invention are, first, to provide a safety device applicable to any ordinary form of window, that neither obscures the vision or obstructs the free passage of air or like, but which effectually prevents leaning far outward and the danger consequent upon such action.

A second object of the invention is to provide such means that can be placed in position to operate in a window frame or withdrawn by persons without previous experience and which are particularly useful in protecting children from dangerous falls from such openings.

A third object is to provide a device which can also be used as an outside support for persons imperiled as in case of fire.

A fourth object is to provide means whereby various articles such as potted plants, domestic utensils and the like, may be safely disposed within the window space, the articles being readily accessible from the inside of the window.

These and other objects, such as simplicity of construction and operation, cheapness of manufacture and general adaptability, are attained by the novel combination and construction of parts hereinafter described and shown in the accompanying drawing, forming a part of this specification and in which Figure 1 is a perspective view of the ap paratus, the bars being shown in raised or operative position. Fig. 2 is a side view of the same. Fig. 3 is an enlarged side view of the casing and mechanism, looking from the inside. Fig. 4: is an enlarged fragmental view, showing the interior at one of the upper corners. Fig. 5 is a sectional view of the same, taken on line 5-5 of Fig. 4:. Fig. 6 is a fragmental view, showing a modified form of construction, and Fig. 7 is a fragmental sectional view, showing a modified form of bar lock.

The construction includes an open frame l walls 15 of which have a series of perforations 16 for purposes later evident.

In the upper ends of the guides 14, transversely across, are rigidly mounted square shafts 18, having affixed on them, between the sides of the guides, drums 29, to the periphery of which are attached the inner ends of fiat, loosely coiled, spiral springs 17, the same being under tension when placed in position and exerting force in a clock-wise direction, as indicated in Fig. 5. To the outer ends of these coiled springs 17 are attached the ends of chains 20, which are of sufficient length to extend to the bottom 21 of the guide plates 14:. These chains, which are disposed in parallel, are wholly contained within the guides 14:, and are attached at their lower ends permanently to the bottom members 21 of the guides; they also have attached to them, at regular intervals the ends of cross bars 22, 23, and24, arranged to slide freely up and down in the guides 14 when operated, or to be contained in close proximity at the bottom of the apparatus, at which time the springs are further tensioned and exert suflicient force to draw the chains and bars upward when released.

The upper bar 22 is preferably made of a tube containing rods 25 slidable therein and held normally separated or extended by a helically wound push spring 26 positioned between the rods near the center of the hollow bar 22, which at this point has an opening 27 through which extend the finger grips 28, one of each being rigidly engaged with the inner end of the corresponding rods 25. The outer ends of these rods are adapted to extend through the bar 22 and engage with the perforations 16 so as to be locked therein by reason of the spring pressure exerted between them, but are readily retractable upon pressing the grips 28 to ward each other, thereby permitting the bar 22 to be moved up and down and engageperforations as may be deterior construction asabove it is evident that the bar may be made of springmaterial so that when the center is pushed either in or'outythat is in either-direction laterally, theends would becOmedisengaged from the openings allowing the bar to be moved as before stated. V

' In the modification shown in Fig. 7, in place of the bar 22 another style of bar is shown, also hollow and containing rods 31 each having a shoulder 32 at their inner ends against which abuts the ends of helical springs 33, the other ends of springs being held under tension against the collars 3 1 rigidly set in the tubular bar .30. In this type of bar a reverse action of the rods is attained, the rods being normally forced to the center; a space is provided between them and in this space is a cam 35 having a stem 36 entering the walls of the tubular bar so as-to rotate freely therein; one end of the stem is fitted to receive a key, or its equivalent, by which the cam can be rotated and it will be evident that a quarter turn of the same will force the rods 31 outwardly, their extreme ends entering into the perforations 16 and positively locking there until the key is applied and the stem further rotated.

In Fig. 6 a slightly different arrangement is shown, in which the arm is made in two parts 40 and 41 respectively, one being adjustably slidable on the other, and held in relative position by the bolt 43 passing through a slot formed in one or both of the arms.

Immediately adjacent to the plates are be evident that the bars can be moved out of position'or selectively engaged at any height within the guides. It is further noticeable that in case of fire, one can step out on the window sill and Support himself from falling by grasping the bars.

Having thus described my invention, what I claimas new and desire to secure by Letters Patent is In a safety device for window. openings,

a rectangular frame removably engaged in the window opening, arms extendlng ad nstably rearwardly beyond the window frame, oppositely disposedchannel guides supported by said arms, a pair ,of springs contained in the upper portion of said channel guides,

chains connected with said springs, secured at their opposite ends to the lower ends of said channel guides, bars engaged at spaced. intervals with said chains slidable within said hannel g ides, n e n comb ed with the uppermost of said bars whereby it may be positivelyheld at certain predetermined heights therein.
