The prototype stainless steel ashtray for the 1954 Greyhound Scenicruiser bus was one of nearly 100 prototypes, models or parts Raymond Loewy Associates hired Model Builders, Inc. to fabricate in the 1950's. Raymond Loewy Associates was responsible for the design and prototype of the Scenicruiser bus. The Scenicruiser is listed in several prominent design books as one of the 100 best designs of the 20th Century.
We thought you might enjoy learning about this unique modern ashtray design. The prototype is up for auction for the first time on Thursday October 17, 2013 at www.wright20.com as lot 175. See http://www.wright20.com/auctions/view/QU2E/QU2F/175/lotno_asc/none/Q8WB/ .
The ashtray is 4 1/2" wide X 4 1/2" high X 1 1/4" thick.
Above are some sketches of the ashtray made prior to the fabrication of the prototype.
This sideview shows the ashtray in the open position. The pivot point for the front section of the ashtray is at the pin head shape at the bottom. The curve at the top is to keep ashes from falling onto the back of seat it is mounted on.
Just rotate the lever downward to dump the ashes or cigarette into the chamber below.
The front/two sides of the ashtray is a pressure fit with two dimples (one on each side near the top) locking it in the closed position. Simply slide the ashtray up off the mounting plate and open up the front/sides by pulling outward the top of the two sides The masking tape on the edge was added to tighten the fit on this prototype. In production the fit would be more precise due to more accurate tooling so there would be no need for the tape.
The fixed mounting plate allows the back side of the ashtray (as seen on the right) to slide down and up easily so the ashtray can be opened, dumped and cleaned frequently.
The patent was applied for but as far as we know was never granted. Note the hinge along the bottom of the ashtray. The "dimples" on the front are a nice design touch.
