MECHANICAL MOVEMENT INVE l au rez/@e6 Zigi/1 er,

Patented Feb. 11, 1941 UNITED vSTATES PATENT OFFICE 5 Claims.

The present invention relates to an improvement in mechanical movements.

While the present device is adaptable to other uses, it is shown herein as a means for operating a swiveled, non-draft Ventilating window for closed automobile bodies.

Two forms of the toothed actuating means are shown, these both being substantially equivalent in function, and they both comprise interrneshed, toothed, reciprocatable actuating means which translates motion, from. a primary driving source, to a to and fro operatively driven means located at right angles to the primary means.

The foregoing function lends itself admirably to manual operation, from the inside of an automobile, to operate the Ventilating section of the windows, for the purpose of opening and closing the ven-tilating Window section for ventilating the interior of closed car bodies in a draftless manner, in accord with current practice.

The foregoing, and other features of advantage will be apprehended as the herein description proceeds, and it will be obvious that modications may be made in the structure herein disclosed, without departing from the spirit hereof or the scope of the appended claims.

In the drawing,

Fig. 1 is a sectional View taken on line I-I, Fig. 2, looking in theV direction of the arrows;

Fig. 2 is a perspective View looking at the bottom of the preferred form of structure; and

Fig. 3 is a View in side elevation of a modified form of right angled motion translating means.

In Figs. 1 and 2, the motion translating means comprises, a preferably metal angle iron b'ase I, which may formr the frame or sill of the window opening in a door, though this detail may be varied, as may other details shown herein.

Gn the inside, adjacent faces of the angle iron base I is slidably located a double toothed, right angled, rack element generally denoted by .5, Figs. 1 and 2, said rack being nested or fitted for a limited, reciprocal sliding movement, to and fro in the inside angled seat of the angle iron I, as shown in Fig. 2.

, The rack B comprises a right angled structure, having gear or rack teeth o-n each angled edge so as to provide toothed engagement with two toothed pinons 4 and 5, which are rotatively and angularly mounted in the angled webs of the angle iron I, as Vvll be seen in Figs. 1 and 2. Each pinion, 4 and 5, are engaged with their respective toothed portions of the angled teeth (Cl. i4-422) on the right angled rack element 6, said pinions being rotatively located at right angles to each other in the webs of the angle iron base I, and each pinion being provided with a preferably, integral shaft, 3A and 2, respectively, whereby the rotation of pinion 4 operates to slide the right angled rack element 6 to' and fro and this rack movement causesk rotaryv movement of the pinion 5.

The stub shaft 2 of pinion 4 has an outer extension which passes through one leg of the angle iron 6, as best seen in Fig. l, and upon this extension is Xedly mounted the hub I9 of an operative handle II-I2. A washer I5 may be mounted upon said extension and a nut I3 may be threadedly engaged upon the end of shaft 2, to secure the handle assembly in rotative drive assembly with the pinion 4, whereby said pinion may be rotated to reciprocate rack 6.

The other pinion 5, Fig. 1, also has an extension of its shaft 3, which is rotatively mounted through the other web of angle base 6. A spacing collar I4 may be mounted upon the extension of shaft 3, which rotatively passes up through a frame base plate or strip I5, and a base channel section I6, the extension of shaft 3 being threadedly engaged by a nut I'I, so as to fixedly secure the base channel section IG, so that when pinion 5 is rotated, the channel I6 is oscillated on the base plate i5, said plate forming, in some forms of window construction, a xed, non-movable window frame or sill forming member at the bottom. of the ventilating window section, Said sill forming member I5 being fixed to the window frame forming section of the door. Other means for accomplishingv a structural embodiment for forming a frame and sill forming structure may be utilized.

The Ventilating, oscillatable window, as seen in Figs. 1 and 2 comprises a glass window pane section I9, which is fixedly mounted in a surrounding metal channel section I8,which in mo-st cases, completely surrounds the outer edge or contour of the glass pane I9. As noted in Figs. l and 2, the channel I8, at the lower edge of pane I9, ts into the channel I6, between the flanges thereof, so that any radial movement of the channel IB caused by the rotation of shaft 3, acts to swivel pane I9 to open or close the pane section I9 and its supporting channel I8. The upper edge of the pane I8 and its pane I9, may be pvotally supported by an axially located pivot, not shown, but Well known in this art.

Both pinions 4 and 5 are provided with short, integral tit extensions 8 and 1, respectively, Figs. 1 and 2, at their external faces, and these tits are utilized so receive thereon the open ends of a coiled, compression wire spring 9, Fig. 1, whereby to keep both pinions 4 and 5 compressively seated against the respective faces of the angle iron webs. This spring while acting at all times to resiliently maintain said pinions in their respective operative positions relative to their respective rack tooth engagements, also constantly acts, resiliently, to exert the seating pressure on said pinions, during any rotative motion translation thereof, as, obviously the spring 9 is resiliently reacting to any rotative action of the pinions 4 and 5.

While spacing rings and collars, have been described in the foregoing disclosure, obviously, aside from the main motion translationI above described, modifications, substitutions, or alternative constructions may be provided, to suit conditions of local assemblies, without departing from the main feature of the main idea of the pinion and right angled rack motion translation means, as above disclosed.

An alternate form of motion translation means is disclosed in Fig. 3, wherein there is shown a skeletonized assembly of two pinions 4 and 5, each provided with shafts 2 and 3, only one shaft 2 being shown, each pinion having the external stem extensions 'l and 8 as described for Figs. 1 and 2, for the same purpose as described for said latter figures.

In Fig. 3, however the right angled and toothed motion translating means comprises what may be termed a circular, angular rack, having a set of internal teeth to engage with pinion 5, and a set of horizontal teeth 2| to engage with the pinion 4. The cross section of this circular tooth rack or ring gear is identical with the angular cross section of the angular rack 6 of Figs. 1 and 2, but as shown and constructed in Fig. 3, the rack is circular and endless. The function of the circular rack 6 is identical withk that described for Figs. l and 2, in that rotative movement of the pinion 4 causes a right angled motion translation to the pinion 5. Both pinions may be rotatively mounted upon an angle iron base l, and the tits 1 and 8, Fig. 3 may also receivably seat a coiled spring 9, for the purpose and function as described for and disclosed in Figs. 1 and 2.

In Figs. l and 2, the right angled tooth rack 6, may be of suiiicient length to permit of the rotation of the ventilation window pane I9 and its appurtenant rotative parts from the closed position to an open position of approximately ninety degrees from said closed position.

In general operation, as a Ventilating window control, the device as shown in Fig. 1, the nut I3, may be so frictionally tightened as to permit of -easy operation of the handle II--I2, to open or close the window section l8|9, but due to the friction thus created by the securing means to prevent the closing of the Ventilating window section by wind pressure, this being one of the objects of the present improvement. Other means may be utilized to provide a means for preventing window closing reaction by the wind,

when the window is open, but at the same time to permit easy opening or closing of the Ventilating window section from the inside of the vehicle by the handle Il-I2, and thus the Ventilating Window section is controlled by an irreversible geared control for the purpose herein described.

In other uses of the mechanical movement herein disclosed, the structure of Fig. 3 permits of unlimited circular or angular motion so long as the pinion 4 is rotated in either direction.

Having thus described the invention, what is claimed is:

1. A mechanical movement comprising rotatable toothed pinions, a base for rotatably supporting said pinions at right angles to each other, an intercepted rack toothed member movably supported for movement by one of said pinions, said last member being of angular construction and having toothed means engageable with the teeth of said pinions, whereby to angularly translate motion from one of said pinions to the other of said pinions and resilient means for holding both said pinions in motion translating position.
