This invention relates to window ventilators and more particularly to a ventilator that is attached to the'sash of a windm- In thepast, ventilators provided for windows havebeen mounted in a permanentfixed position onth sill of the window or between-jamhs of the window, and being permanently f xed couldnotbe moved with-"the sash or adjusted..- .-Also, in home usetit isdesirableto raise the' window at times in order that-@sornething may be .passedout 'of 7 the window. as the ventilator. obstructs theapasw sage, and the kndwn ventilators have always been in the way in such instances.

An object of this invention is to provide a ventilator for a window that may be raised and lowered with the window.

Another object of this invention is to provide a ventilator for windows that may be adjusted to hold the sash at any desired degree of opening.

A still further object of this invention is to provide a ventilator for a window sash that may be screened permitting the air to pass through but preventing insects from passing through.

Other objects of this invention may be apparent by reference to the drawing and detailed description in which,

Fig. 1 is a perspective illustrative of the ventilator mounted on a window sash.

Fig. 2 is a perspective view of the ventilator with a screen mounted therein.

Fig. 3 is an elevational view of one upright of the ventilator as it is formed in stamping.

Fig. 4 is an elevational view of the other upright, and

Fig. 5 is a perspective view partially in crosssection illustrating the formation of the lower portion of the upright in Fig. 3.

In the embodiment of the invention illustrated in Fig. 1 there is a ventilator l illustrated as being mounted on a window sash l l. The ventilator Hi includes a pair of uprights l2 and a pair of glass supporting uprights I3. The uprights I! are formed with a long slot l4 cut in the center of the uprights. A plurality of screws attaching perforations l are provided in the upright l2. The uprights l3 are formed as illustrated in Fig. 3 with the upright portion [6 having two perforations IT and a handle or turned over end !8. The upright I3 also has an enlarged lower end IS in which a slot is provided or formed. The upright l3 has its lower end portion l9 bent in at a right angular formation as indicated in Fig. 1 so that a portion 2! is at right angles to the portion IS. The uprights l2 and Bare both formed with a slight bellied formation or mating tracks in the centerysectionfi 2- so that a pairof bolts-23' q having enlarged pontions fl may be fitted behind the uprigh-t'iflithrouglrsthe"sloti f4 through :the V perforation-ll and w henin place: the innervface" ,r;gif i ip1 ightil2 ma y-be in-line with the heads zt of f the, =bc1ts:-23 .e A -wingnut is provided =for each of thebolts zliandras illustrated in Fig. 1 is the" meansoi tig htening the relationship betweenthe uprightsd-i' anddirtohold them in any set rela- T 10% itionship. Referring to .5 .Jthe =p'ortion-2 i of In use the ventilator is mounted by attaching the upright I2 to the sash of the window with the bolts 23 mounted in the slot I l. The upright I3 is next placed so that the bolts 23 are passed through the perforations I! and the wing nuts 25 are threadably secured on the bolts 23. When both pairs of uprights have been mounted a glass or any form of desired material may be inserted in the slots 20 after it has been cut to the exact size for the window as in the portion illustrated in Fig. 1; or an adjustable glass may be inserted, thus the room or interior may be provided with the necessary ventilator. However, the opening of the sash with relation to the ventilator, may be adjusted at will. Also, the ventilator may be held firmly to the sash and may be raised with the sash.

Another embodiment of this invention is illustrated in Fig. 2 in which the uprights I2 and I3 are similar to those described in the former embodiment but in this instance a screen 30 is cut and formed as illustrated in Fig. 2 and may be inserted either with a glass or with a portion of glass or without the glass to provide the necessary ventilator and at the same time the necessary protection of the ordinary screen.

Although preferred forms have been shown it will be understood that a mechanical working within the scope of what is claimed, may make changes, without departing from the spirit of the invention.

What is claimed is:

1. In a ventilator, a pair of channeled uprights fixed to a sash, a second pair of uprights formed to mate with and slidably attached to the first mentioned uprights, a pair of side enclosing members connected to the second mentioned pair of uprights and provided with aligned grooves to support a glass in said members, said glass supporting'means having its aligned slots disposed at an angle to said first pair of uprights to retain said glass, and means to position said second uprighta i8- is-iormed at right angles to the por 3 mentioned uprights in a set relationship with first mentioned uprights.

2. In a ventilator including two channeled uprights permanently fixed to the sides of a window sash, two movable glass supporting side shields 6 with parallel extensions, said permanently fixed uprights having slots running the full length of said channels, said glass supporting side shields having extended uprights formedto mate with said permanently fixed uprightsj'saidextended 1 uprights of said glass supporting shield-s having a. pair of clamps that are fitted into the said supporting side shields in a set relationship wit the first mentioned pair of uprights. v

3.
