TURN-BUTTON.

Application filed. April 7, 1916.

To all whom it may concern:

Be it known that I, BERTHOLD JAHN, a citizen of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Turn-Buttons, of which the following is a specification.

My invention relates to improvements in turn-buttons, and the object of my improvements is simplicity and economy in construction and convenience and eiiiciency in use, and is particularly adapted to use where the base portion on which the moving portion or turn-button proper is mounted is low or relatively fiat, whereby a relatively thin eye member may be used, and the same will be securely held in place.

In the accompanying drawing :Figure 1 is a front elevation showing a circular window sash for a wind shield for an automobile, held in place by means of a pair of my improved turn-buttons. Fig. 2 is a similar view on an enlarged scale of a portion of the same. Fig. 3 is a similar view of the window frame. Fig. iis a rear elevation of the same. Fig. 5 is a sectional view, on a still further enlarged scale, on the line at w of Fig. 1. Figs. 6 and 7 are similar views showing modified forms of base structure.

As shown in Fig. 1 a pair of my improved turn-buttons is used to hold a circular window sash 10 in place in a frame or casing, the latter being of the style that is secured to the border portion of an opening in the glass of the wind shield of an automobile,-

whereby is illustrated one manner of using the said push-buttons. In the drawings the front ring or plate 11 of the said casing only is shown, and the same is provided with a pair of laterally extending ears 12 on each of which is mounted one of the turn-buttons.

The sash 10 comprises a pair of rings 19 of sheet metal, between which is positioned a transparent pane of celluloid or other suitable material. The rings 19 also have laterally extending ears 14 that register with the ears 12 and which ears have elongated openings 17. On each of the ears 1 1 is mounted an eye-piece 15 having an elongated oval opening in registration with the opening 17 and which has a convex form of crosssection for the front face. Thus the eye-piece 15 forms a border for the elongated opening 15 in the sash 10, and is the Specification of Letters Patent.

part that engages with the rotated portion or turn-button proper of the turn-button, and which is to be described.

The eye-piece 15 has on the inner edge portion, at opposite ends of the smaller diameter of the opening 17, a pair of depressions or notches 18 that serve as seats for the turn-button proper in the locking position.

The turn-button is secured to the ear 12 of the casing plate 11 by means of a basepiece 21. As shown the said base-piece 21 is secured to the car 12 by means of a pair of lugs 22 that extend through the material of the said cars 12 and are bent over on the rear side thereof, the ear 12 being slightly upset as shown at 23 to provide a housing for the ends of the said lugs 22. The basepiece 22 on the front side of the ears 12 is cup-shaped and comprises a supporting plate 2% suitably spaced from the ear 12 to provide a housing for the head 26 formed by riveting over the end of the pin 27, which supporting plate 24 has a central hole 25 that iits the body portion of the said pin 27. Thus the base-piece is secured to the ear 12 and serves as a mounting for the pin 27, and thereby serves as a support for the rotative portion or head 28 of the turn-button. The said head 28 as shown comprises a tubular barrel 33 at the middle and a pair of platelilre wings 29 one on each side thereof, and

positioned in an axial plane. ihe front end of the barrel 33 may be open as shown. Atthe rear end the barrel 33 is closed by a bottom plate 30 having a central opening for the pin 27 he head 31 on the front end of the pin 27 is a. fit for the barrel A spring 32 is mounted. on the pin 27 and has its ends in bearing engagement, one with the head 31 of the pin 27 and the other with the bottom plate 30 of the head 28.

The spring 32 tends to push the head 28 rearwardly, toward the supporting plate 24: of the base-piece 21, and serves when in use to hold the wings 29 in the seats 18 of the eye-piece 15 and thereby to hold the sash 10 against the frame plate 11.

The longer axis of the hole 17 is of suiiicient length to permit the head 28 to pass freely through the hole 17 when turned to the unlocking position and the shorter axis is of such length that the head 28 bridges the opening 17, thus permitting the wings 29 to engage with the seats 18 as described.

The head 28 is generally a cup shaped structure, having the bottom closed except for the perforation or hole 31 for the pin 27, and the wings 29 and the barrel 33 formed simultaneously by compressing together the wall structure on each side of the said barrel 33. Thus the side wall of the head 28 consists of an endless structure of sheet material, the wings 29 being formed by a double-thickness of the said material.

In the modification shown in Fig. 6 the supporting plate 24 that engages with the pin or shaft 27 is integral with the car 12, being formed by extending the upset portion '23 0f the said ear 12 suflieiently to provide the desired elevation of the said supporting plate 24:.

In Fig. 7 the construction is generally similar tothat shown in Fig. 6 and differs therefrom in having the upsetting of the car 12* as shown at 23 only such as is necessary to house the riveted head 26 for the pin 27".

The lower corners 35 are rounded as shown to facilitate the turning of the head 28 for engaging and disengaging the eye-piece 15.

As described the head 28 is held in resilient engagement with the eye-piece 15, and the spring means for effecting such resilient engagement are housed in the head :28. This as shown by the various modifications permits the lower engaging portions of the wings 29 to be positioned as close to the ears, or whatever serves as the support for the turn-button, as desired and independently of the mechanism that is used for pro viding the desired to and fro movement of the head.

The fact that the securing means for securing the rotating head 28 to the platform portion 2a of the sheet metal ears 1% consists simply of a riveted head 26 on the pin 27 serves to permit of operatively mounting the head 28 particularly close to the general surface of the ears 12, and without obstructing the general rear surface thereof, as by providing a slight upset for the platform 24 sufficient to house the said riveted head 26 on the rear side the said rear surface of the cars will be entirely free and unobstructed.

By rounding the lower outer corners 35 of the head 28 as described the head 28 is better adapted to cooperate with the walls of the eye-piece 15 when rotated, permitting of being more easily rotated, the said Walls bottom having a hole that fits the said pin,-

a barrel extending outwardly from the said bottom, a head on the outer end of thesaid pin, positioned in the said barrel, and a spring mounted on the said pin and positioned between the said head and the said bottom, the said supporting plate having a hole that fits the said pin, and the said pin extending through the-said hole in the supporting plate and having a riveted head on the end that serves as the means for holding the said head operatively mounted on the said supporting plate.

2. A turn-lmtton comprising a supporting plate, a pin extending outwardly from the said supporting plate, and a head mounted on the said pin, the said head comprising a bottom having a hole that fitsthe said pin, a barrel extending outwardly from the said bottom, a head on the outer end of the said pin, positioned in the said barrel, a spring mounted on the said pin and positioned between the said head and the said bottom, and a pair of wings extending laterally from the said barrel and the lower, outer corners of the said wings being rounded suitably to serve as bearing surfaces in cooperation with the walls of an eye-piece.

3. A head for a turn-button, generally cup-shaped, formed of sheet-material comprising an endless side wall, the said side wall having opposed portions that are in spaced relation and of suitable shape to combine to form a barrel, and radial wings on each side of the said barrel formed of a double thickness of the said material, and a perforated bottom at one end of the said head.
