1 Claim. (Cl. 206-19.5)

closing the ysuction tube valve.

In accomplishing these land other objects of the invention, we have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of the ash and cigarette disposal device of the present invention, showing, in full of the tray.

Fig. 3 is a cross-section taken on line 3-3 in Fig. 1. Fig. 4 is a vertical, sectional detail of the front end portion of the tray and its support. l Referring more in detail to the drawings: The present ash and kinds,

means of a bracket v29,

pant of the drivers or front seat.

In Fig. 1 We have shown the at and rectangular, posed with its forward at this end is by means of a screw bolt 16 Iapplied through the flange 15 and plate as shown best in Fig. 3.

The plate 11 1s also equipped at tained. The closing movement by the end plate 19'contacting the forward edge of the top plate 1111 as the tray To withdraw smoke and fumes of burning the closed tray, we provide a suction tube lead from a connection with the suction butts from housing 2S is formed axially with a cylindrical valve chamber 30 in which a other end is, toward its closed position.

On the top of the valve housing 28 is a tubular nipple 40 which opens at its inner end into the valve chamber and is controlled by the valve member 31. Likewise formed on the bracket 29 is an upwardly directed tubular nipple 41, the passage of which opens through the bracket and the top plate 11 as seen in Fig. 2. A short rubber over Vthe nipples '40 and 41, thus to provide a connection for an application of suction through the -tube 25 to the ash tray under control of thevalve member 31.

The valve member 31 is formed on that end which is opposite the bored end with a stem 45 that extends from that end ofthe valve housing. This stem is equipped at its end with a head 46 which is adapted to engage the end cap of the valve housing through which'itfextends to llimit vits inward movement `into the valve housing. When the -ash receptacle is fully closed, its inner end wall engages the head 46 of the stem 45 and retains it inan open position as in Fig. 2 against the pressure of spring 36.

Reference numeral 44 designates a screen which is secured over the inner end of the passage through the nipple 41. The screen prevents ash and other matter from being drawn out through the passage and also the screen reduces the opening and serves as a metering means to reduce the vacuumatic action. In lieu of screen, a smaller hole or opening into the receptacle would produce substantially the same result.

Assuming the various parts to be made and assembled as shown in Fig. 2, it will be understood thatwhen .the tray 10 is adjusted to an open position, as in Fig. l, to receive ashes, the valve member 31 is released and .will be moved forwardly in the valve housing by the spring 36 to a position at which it closes over the suction connection with the nipple 40. However, when the tray vis again pushed to a fully closed position as in Fig. 2, its end wall 10c will engage the head 46 the `valve member 31 and shift the valve against the pressure of spring 36 to a position at which the channel 33 communicates with the passage of nipple 40 and thus completes the suction connection to the tray through the hose connection 43. When this connection is made, smoke or fumes from ashes or burning butts will be sucked from the container and not allowed to pass into the vehicle.

'Such trays may be equipped, if it is so desired, with a corrugated cross strip as shown at 50 as a support on which a burning cigarette can be laid.

of the stem of Itis understood that various ways or means other than herein illustrated might be employed for the mounting of the valve housing, or the mounting of the cover plate 11, and it is not desired that the following claims shall be restricted to the means herein shown. The novelty of the present invention is thought to reside in the present type of suction connection, and a valve for that connection that is operated automatically by the positioning of the tray, to apply suction to the tray only when it is in a fully closed position.

Such trays are easily withdrawn from their lsupports for cleaning and can be easily replaced therein. When applied, as here shown, and then drawn to an open position, they are conveniently accessible to persons occupying the front seat of the vehicle.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

An ash tray, a rectangular cover plate applied thereto, ilanges on the sides of said tray and anges on the sides of said cover which cooperatively provide a sliding connection that permits movement of the tray between coveredand uncovered positions, a bracket iixed to the outer surface of said cover plate, a suction valve means rnounte bysaid bracket and comprising a valve housing disposed in the line of `movement of the tray to its closed position, said valve housing being formed lengthwise with a cylindrical chamber with means at one end for its connection with a source of suction, a suction connection leading laterally therefrom and opening through said cover plate into open communication with the tray when in covere position, a valve piston reciprocally contained in the cylindrical chamber, a spring contained in the valve housing and acting against said piston to urge it to its closed position, said piston having a stem extended therefrom `anddirectly vengageable by the tray as it is moved from an open position to its fully closed position to open the valve-for an application of suction to the tray.
