6 Claims. (Cl. 292-337) This invention relates generally to latches, and pertains more particularly to an improved form of latch for securing automobile windows against being opened from the outside.

In various types of automobile body windows, particularly those of the type popularly known as no-draft or individual ventilating windows, a glass pane is mounted in a metallic stile which is adapted to be swung or rotated on vertical pivots and the car body is customarily equipped with a suitable crank and gear arrangement for so operating the stile and pane. Most of such windows ordinarily may be forced open from the outside to the extent adequate to permit the insertion of a wire or thin strip of metal which may be engaged with the door latching device to operate it to unlock the door.

One of the general purposes or objects of the present invention is the provision of an improved form of securing latch which may be easily mounted on and aflixed to a window of the foregoing description and which will be efiective to prevent opening of such a window from the outside, and thereby frustrate unauthorized access to the interior of the vehicle body in the manner above described.

Another object of the invention is to provide such a latch which may be mounted and supported securely on the stile of the window in such fashion as to prevent its imparting injurious pressures to the window pane.

Yet another object is the provision of such a latch which is tamper-proof from the exterior of the vehicle body so as to preclude unauthorized operation of it.

Still another object is the provision of such a latch which is very rugged and strong, but at the same time of small and unobstrusive size and design and of sightly appearance.

Another object of the invention is the provision of an improved construction for a latch which is adapted to be applied to the marginal portions of a door, window or the like, and which may be manufactured economically. I

Other and further objects of the invention will be pointed out or indicated hereinafter or will be apparent to one skilled in the art from the following description and explanation.

For the purpose of aiding in an explanation of the invention, I show in the accompanying drawing forming a part of this specification, and herein after describe, one structural form in which the invention may be embodied. It is to be understood, however, that this is presented for purpose of illustration merely, and is not to be construed in any fashion calculated to limit the appended claims short of the true and most comprehensive scope of the invention in the art.

In said drawing,

Fig. 1 is an inside elevational view of an auto- 5 mobile body window of the so-called no-draft or individual ventilating type, the same being equipped with a latch in accordance with my invention;

Fig. 2 is an end elevational view of a latch em- 10 bodying my invention, illustrating the relationship of same to the bottom stile and pane of an automobile window such as illustrated in Fig. 1 when the latch is applied thereto in position shown in Fig. 1; 15

Fig. 3 is an end elevational view of said latch showing the end opposite that shown in Fig. 2;

Fig. 4 is a side elevational view of the same latch showing the side which is presented toward the inside of the vehicle body;

Fig. 5 is a sectional detail taken on the line 55 of Fig. 4; and

Fig. 6 is a plan view of a blank from which the body portion of the latch may be formed.

The nature of the invention will be most quickly ascertained from a detailed explanation of the embodiment shown in the drawing, which will now be described.

In Fig. 1 is shown an inside view of a side door window construction for an automobile of the rigid-body roadster or sedan type. The reference character A designates a portion of the door or side wall of the vehicle which is formed with the window opening. The reference character B designates a window pane which may be either stationarily mounted or mounted for vertical sliding movement in the door or body, said pane being guided at one vertical margin in a stationary guide C which may be a metallic channel. The reference character D designates the pane of the no-draft or individual ventilating portion of the window, said pane being mountedin the stile E, which is in the form of a metal channel or the like, which embraces its top, front and bottom margins. The stile E and window pane D are mounted for rotary or swinging movement on vertical pivots which are indicated at F.

It will be understood that the latch illustrated 50 in the drawing is designed for use on a window at the right side of an automobile body, and that a similar latch may be provided for use on the left side window, same corresponding in all particulars to the construction shown in the draw- 55 ing, with the exception that the parts are in reversed relationship.

The latch comprises a body portion having side walls I and II arranged in spaced, approximately parallel, relationship and joined by an end wall l2 and a bottom wall I4. The spacing of the side walls I0 and II is adequate to accommodate the introduction of the window pane D therebetween, and the lower portions Illa and Ila of the respective side walls are, spaced at a somewhat greater distance to accommodate introduction of the window stile E therebetween and are formed with inwardly offset parts .10 and p. The inner side wall is provided with an outwardly offset bolt housing I5, within which is slidably mounted a stiff bolt I6 having a lat erally offset nose portion Mia. The bolt housing portion is slotted at I51) to accommodate the shaft of a headed thumb screw I! which is screwseated in the bolt l6. As seen in Fig. the inner side of the bolt is somewhat countersunk about thescrew hole, and the end of the screw is peened-outwardly or upset to forrna projecting stop I'Ib which prevents removal of the screw from the bolt, yet permits a certain extent of inward and outward movementof thescrew upon its rotation in the appropriate direction.

Alatchof the foregoing description is applied to the window by inserting the marginof the pane between the walls. Ill. and II and the end portion of the bottomstile betweenthe wall por tions Illa and Ila so that the offset parts 1; and p overlie the inner marginsof the stile, and moving the latch along the pane until the margin of the latter abuts the end wall I2, a suitable cementitious material I8 being disposed. within the lower portion of the body member, said cementitiousmaterial being of a, sort to ,set in rigid condition and firmly bond. the stile E to the wall portions Illa and I la and the bottom portion I4. When the latch is so, applied and the cementitious material set rigidly, the latch is securely fastened to the stile and held rigidly against flexion or displacement laterally relative to the stile and pane. When the no-draft window is in closed position, the bolt I6 may be slid, by manual operation-of the screw I1, to project the nose portion lBa beyond the end wall I2, so that said nose portion will overlap the inner side of the adjacent vertical guide C. The screw I"! may be set up to secure the bolt in this position by clamping portions of the ofiset portion I5 between the head of the screw and the side of the bolt. With the latch thus set, the no draft window is securely locked in closed position, and any swinging of the window, either by forcing from the outside or by operation of its normal operating mechanism, is definitely precluded. Bolt I5 may be moved to the retracted, or unlatched, position by loosening, the screw I1 and sliding the bolt to the limit of the slot 'I5b, whereupon the bolt may be secured in the retracted position by'setting up the screw I'l.v In this position the nose Ilia of the bolt is clear of the guide C; and the no-d'raft window may be operated in the normal fashion.

The body portion of the above described latch may be formed from an integral blank of sheet metal, such as stainless steel, in the form shown in Fig. 6. This blank is bent on the dotted lines 9 to give the wall portions III, II and I2 their respective positions, on the dotted lines h to form the part p and. offset the wall portion Ida, on the dotted lines 2 to shape the bottom wall M, on the dotted lines 70 to form the part 1) and offset the wall portion I la, and on the dotted lines m to offset the bolt housing portion l5 and form the marginal flange I 9. When these bends are made in the form illustrated in Figs. 2 and 3, it will be seen that the bolt housing portion is brought into overlapping relationship with the side wall portion I l, which side wall portion has at its upper margin an extension 20 which is flanged down across and against the outer side of the flange I9, to secure the overlapping parts fixedly and permanently together. The side wall portion II has at its lower margin a narrow flange 2! which is bent outwardly along the dotted line 12 into engagement with the inwardly offset portion 11. The bolt I6 is then slid into place in the bolt housing 15, and the screw I! inserted and screwed down fully, whereby the previously concave end of the screw is peened or upset outwardly as it is forced against the surface of the wall portion H, the portions II and I5 being. held by a jig against separation. If desired, for purpose of additional strength, the overlapping portions may be spot-welded at the point to. Y I

From the foregoing description it will be seen that my improved construction. provides. a latch which is very compact and light, but at the same time very strong, and that when attached to the stile as explained above, theparts are held rigidly against transmitting any pressure to the pane. Furthermore, it will be observed that the. latch does not interfere with the normal operation of the door or window in any manner, yet holds the window securely locked. against opening to even the slightest degreer Sometimes the operating mechanism in windows of the character above referred to becomes worn to a degree such as to allow the window to swing more or less incident to the swaying of the vehicle or under wind pressure. My latch is effective to holdthe window securely closed under such conditions. The fact that the. bolt may be securely fastened ineither the latched or retracted position prevents any rattling of the bolt and also affords additional security against unauthorized operation of the latch.
