ARTHUR A. came, on CHICAGO, ILLINOIS.
WINDOW VENTILATOR.
Application filed January 14, 1922. Serial No. 529,116.
To all whom 2'22 may concern:
Be it known that I, ARTHUR A. CRAI a citizen of the United States, residing at Chicago, in the county of Cook and. State of Illinois, have invented a certain new and useful Improvement inVV-indow Ventilators,
cise, and exact description, reference being had to the accompanying drawings forming a part of this specification.
a My invention relates to window ventilators. I
My invention has particular reference to that type of window ventilator comprising two or more panels carried inv extensible relation, so that the device may be adjusted to fit various size windows. In this type of ventilator, the panels usually lie face to face, and their engagement controlled by adjusting bolts, conveniently disposed for manipulation to vary the relative position of the panels. The panels sliding against each other offer I considerable resistance, while the bolts tend to bind in the slots carrying them, thereby increasing the difliculty with which the panels may be adjusted.
According to my invention, anti-friction roller bearings are provided in the slotsfor the bolts to reduce wear along the edges of the slots,and to increase the ease with which the panels may be adjusted relative to each other.
A further object of my invention is to construct a simple, inexpensive and easily assembled anti-friction roller bearing, and to arrange it in the slots so that it will not interfere with the relativelyclose relation between the panels. r g
I have observed that considerable diflioulty, is experiencedin preventing the window shade from flapping and eventually tearing itself when loweredwhere a ventilator is mounted in the window frame. This is due to the fact that the ingressing currents of air pursuean upward course, being directed against the inside of the'shade with the" result that it is continuously blown away from the. window. In order to overcome this, I have provided means in the form of holding arms for lying against the lower end of the shade to prevent outward movement by the incoming air.
In order to apprise those skilled in the art how to construct and practice my invention, I shall describe one embodiment thereof.
In the drawings:
Figure 1 is a fragmentary isometric view of a window frame having a ventilator embodying my invention inserted therein;
Fig. 2 is a top end view of the ventilator, illustrating, the shade holding arms in extended position; i
F ig. 3 is a fragmentary end view of the ventilator, illustrating the outer or engaging edge of one-of the panels, and the manner oflaying one of the shade holding arms between thepanels when not in use;
Fig. 4 isa view of the innerend of the panels, illustrating the way in which bind ing strips are laid along the edges of the panels;
Fig. 5 is a developed view of the binding strip laid along thetop and side edges of each panel;

Fig. 1s a perspective view of an antifriction roller bearing;
Fig. 8 is a perspective view of a shade 'of thebolts employed to maintain'the panels but which do not contact over the entire 501,083, I disclose the feature of providing engaging strips having a high frictional quality at the outer ends of the ventilator for holding the ventilator in engagement with the window frame, asfshown in Fig. l. The'advantage of such a construction is obvious, as it eliminates the necessity of providing fastening or looking elements 011 the window frame. I propose to employ this feature in the present invention, but herein illustrate a simplified arrangement over my prior disclosure. As shown in Fig. 3, the panel 3 at its outer or engaging end is provided with a strip 5 in form of a double U, the inner channel of which embraces the panel 3. The outer channels of this strip 5 receive the ends of friction material 6, being held in clamping relation by the flanges 7, which are drawn tightly thereagainst by any suitable means, such as rivets 8. When the panels are extended outwardly, the friction material 6 binds against the sides of the window frame, so that this material 6 is slightly compressed. The panels are then locked together against rela tive movement, and consequently the ventilator tightly holds itself in place in the window.
That part of the ventilators construction which effects its extensibility comprises a plurality of non-registering slots 10 in one panel anzlbolts 11, stationarily mounted in the opposite panel, riding in these slots. As shown in Fig. 6, the bolts 11 consist of the screw 12'anchored in the panel 3 witlrits shank 13 extendingthrough the slot 10 in panel 2.. An anti-friction roller bearing comprising twoconcentric members 14 and 15, is carried upon the shank 13 so that it rides in the slot 10. formed with a shank 16, which is split as indicated at 17 and adapted to be slidover the shank 13 of the. bolt. The head 18rides between the panels 2 and 3m a space formed by means to .behereinafter mentioned. The
bearing member is similarly formed,-having its shank 2O slightly compress the shank 16 asv it slides therein in order that theannular bead 21 will pass entirely through and form an abutment to prevent axial displacement of one shank from the other. Thus the .two bearing members are held tightly with respect to each other, but relative movement is permitted so that one may revolve independent of the other. Thehcad 22 of member 15 is provided with a recess in the outer face, in which head 21 lies, and is of such diameter as to bear along the outside edges ofthe slot 1.0. In drawing up one panel tightly against the other, that is when they arelocked from relative endwise movement, the thumbnut 23 is threaded inwardly on the shank 13, so that its inner end, provided in cup-like form, will surround the head 22 and engage the panel. It will be noted that by this arrangement, the panels may be clamped considerably. tight against eachother without bringing any pressure to bear upon the roller bearing member 15 to prevent its free rotation.
As before mentioned, the panels 2 and 3 are slightly spaced from each other, this being due to the factthat their edges are re inferred by metal strips 25 held in tacked The member 14 is relation. The panels themselves are preferably made out of comparatively light ma terial, such as compressed cardboard, wood, or even sheet metal. The reinforcing strips prevent abrasion of the edges of the panels, and also guard against possible warping. The upper strip 25 as shown in Figs. at and 5 is preferably stamped out so as to fit around the edges of the panel without unduly increasing the thickness. The metal strip 25 is cut away at 27, so that its edges will lie in a single lap about the corners of the panel.
In Figs. 8, I have illustrated in detail a curtain holding arm 27 which is preferably provided in pairs at each end of the ventilator. Thearm 27 comprises a striphaving its inner end bent back upon itself in order to form a hinged joint with the 71119128, anchored at oneside in the panel as shown in Fig. 2. The arm 27 is allowed to swing outwardly sothat its free end holds the shade against the window, and when not in use is permitted to swing against the panel. In one instance, the arm 27 is laid against the panel 3'while the panel 2 is slid over the same in order to suitably hold it from swinging loosely about its hinge when not in use.
In Figs. 9 to 12 inclusive, I have shown alternative forms of roller bearings for the bolts 11. In the first instance, a bearing 30 having a reduced shank 31 is provided with a washer 32 snapped over the end so that it will not bedisplaced. In Fig. 10, theshank 33 is'provided with threads which hold the collar 34 on the shank. In Fig. 11, the hearing isformed with the shank 35 having an annular groove to receive the-split ringBG. The-washer 37 is first placed upon-the shank 85'and the ring. is then snapped over the end to seat inthis annular groove. The form shownin Fig. 12 is similar to that shown in Fig. 10 with the exception of a shoulder 38 which prevents the collar 39 from stripping its internal threads and working its way farther upon the shank 10.
From the foregoing description, itwill be obvious that a simple, yet efficient, ventilator of comparatively light material is provided, which may readily be inserted in a window frame and easily manipulated to obtain a tight fittherein. The roller bearingis. arranged'so that the member'l5iwill be free-to rotate practically at all times, the thumb nut 23 being adapted to draw the panels tightly together without binding'the former against any part.
I claim:
1. In combination, a ventilator comprising a plurality of panels carried in extensible relation adapted for insertion in awindow frame, a plurality of adjusting bolts for locking said panels in extended position,
said panels having slots therein, anti-friction means for said bolts in said slots, and means permitting free action of said anti-friction means irrespective of the degree of engagement between said panels.
2. In combination, a ventilator comprisin g a plurality of panels carried in extensible relation, adapted for insertion in a Window frame, bolts anchored in one panel, the opposite panel being provided with slots therein, anti-friction means for guiding'said bolts in said slots, and means at the free end of 10 said bolts for drawing the panels against each other, Without binding said anti-trio tion means.
In witness whereof, I hereunto subscribe my name this 11th day of January, 1922.
ARTHUR A. CRAIG.
