Claims. 1

The present invention relates to ash receivers and collectors which are adapted to be used in automobiles and equivalent conveyances as well as in airplanes and the like, the same having to do, more particularly, with a collector which is designed for convenient depositing of cigarette butts, cigar stumps and analogous refuse, means being provided whereby the accumulated mass may be satisfactorily disposed of.

As the introductory statement of the invention implies, I am, to an extent, conversant with the state of the art to which the invention appertains and am, therefore, aware that ash receivers with disposal and dumping facilities are not broadly new. In an effort to better comply with what I believe to be the essential requirements of the trade and users, I have devised what I believe to be a collector which is possessed of significant novelty, structural betterments and refinements, and coacting facilities which, conjointly considered, better fulfill the requirements in this field of endeavor. 1

More specifically, one phase of the stated novelty has to do with a simple mechanical grinder which disintegrates .the deposited refuse and reduces it to bits less likely to catch afire from smoldering cigar and cigarette butts.

A further improvement has to do with the disposal means, the latter being connected to and depending from the collector and extending to a point within the vicinity of the ground, when used on an automobile or th like, and terminating in a Venturi funnel which is suflicient to automatically produce suction which plays on the discharge end of the disposal tube and empties the material into the air.

In carrying out a preferred embodiment of the invention, I provide a hooded hopper, hingedly mount a tray-like chute therein, provide disintegrating means which comes into play during the swinging movements of the chute, and

' attach a disposal tube to the discharge of the hopper and connect the tube at its lower end with a Venturi funnel for final trapping and disposal purposes.

Other objects, features and advantages will become mor readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a fragmentary perspective view, showing the instrument panel and floor portion of an automobile and, also, showing my im- Figure 4 is a horizontal section on the line 44 of Figure 2, looking in the direction of the arrows.

Referring to the drawings, and to Figure 1, it makes no difference so far as the invention is concerned, whether the vehicle shown be an automobile, bus, railway train, airplane. or the like. For convenience, A designates an automobile having fioor means B, and instrument panel means C. The essential part of the invention is attachable, if desired, to the panel means C. As stated, the invention is characterized by a casing unit, unitarily designated by the numeral 5 and the latter may be considered as embodying an appropriately proportioned and shaped hopper 6 with a centralized discharged neck I throughwhich the contents empty. It also includes an upper portion which may be conveniently referred to as an open front hood 8, said open front being essentially closed by a panel forming a door 9. This matches the instrument panel and has a suitable hand-grip M. The panel is attached to a hinged drawer-like structure, the principal part of which is denoted by the numeral H and includes a bottom plate l2 with clearance notches H which serve a purpose to be hereinafter described. The corner portion H is rounded to clear the adjacent portion of the hopper and suitable hinging means is provided as at ii. The primary part with which I am concerned is the collector or tray part which is denoted by the numeral l6 and embodies an inclined bottom I! with notches l8, said notches I 8 coaoting with the notches l3. There is an upstanding front wall I! attached to the inside of the door and upstanding end flanges 20. Thus, the tray, in effect, becomes a gravity chute and the cigarette butts, cigar stumps and other refuse deposited will glide down the chute and come into contact with the disintegrating means. This comprises the rotatably mounted shaft 2| having a pinion 22 keyed on one end, said pinion being operatively associated with an arcuate toothed rack 23 fixedly mounted in the hooded portion of the casing. The shaft is provided with disintegrating or chopping and agitating

fingers

24 and 25, and said fingers are arranged to rotate in paths in alignment with the afore- =end of the disposal tube.

mentioned notches i3 and I8. It follows that as the door panel 9 is tilted and swung open for purposes of depositing refuse, the rack and pinion means comes into play and starts to spin the finger-equipped shaft. The fingers rotate through the coacting notches, as is obvious. When the door is closed and the chute or tray resumes the position shown in Figure 2, the articles deposited gravitate down the chute bottom and into engagement with'the rotating fingers. The flngers'obviously disintegrate the deposited articles, and they are churned to bits. By so reducing and virtually pulverizing the articles deposited, there is little likelihood of same catching afire, even where the cigarette butts are left partly burning at the time of deposit. It follows that one aspect of the invention has to do with the hooded hopper, the hingedly mounted door controlled tray or chute, and gearing and agitating and disintegrating means, which is-automatically operable and which reduces the deposited products to substantially harmless bits for final disposal.

v Although the disintegrating and reducing step is, in effect, a part of the disposal means herein referred to, I prefer to envision the latter as having to do primarily with the flexible disposal tube or conduit 26, which is connected with the aforementioned discharge neck I. Then, the tube is carried down to a convenient point just above the ground (not shown) where it is hooked up with the venturi-funnel means 21. The latter comprises a Venturi tube 28 of more-or-less customary design having an enlarged flaring front or intakefunnel 29 and a smaller flaring rear and discharge funnel 30 at the opposite end. There is a nipple 3| provided, and this connects with and projects into the tube 28 where the rear end is bevelled, as at 3|, to create-the necessary air disturbances for proper operational results. The arrow A indicates the direction of movement of the vehicle, and the arrow B the direction of movement of-the air entering the front funnel intake 29.

It is obvious that in operation, after the deposit of cigarette butts and cigar stumps has been made along the lines described, the reduced products empty and discharge by gravity down through the discharge neck by way of the hopper and into the tube 26. Sufiicient suction is produced on the discharge neck I by the ,Venturi arrangement to "pull the ashes, tobacco and pieces of paper, etc., down through the tube.

They finally deposit in the Venturi tube 28,

where they are forced out from the rear by the sweeping air currents. It is evident, therefore, that the articles deposited in my collector are acted upon and reduced to requisite size to be discharged by gravity and, also, by suction,

through a disposal tube, the latter being increased in its efliciency of operation by the Venturi meansattached tothe lower discharge end of said tube.

When installation of ash tray unit is in aircraft, the venturi may be omitted, using only the This tube to be cut off at an anglewith the longest end forward. Also, more than one ash tray may be used on one venturi, such as the front and rear seats of automobiles, aircraft, etc.

A- careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.
