DESCRIPTION:
BRIEF SUMMARY
This invention relates to improvements to stoking apparatus. In particular this invention relates to smoking apparatus for smoking tobacco and for illustrative purposes reference will be made to such application hereinafter. Of course the invention is not limited to such use. Accordingly a reference to tobacco herein is to be understood as a reference to any particulate substance to be smoked.
The most common way tobacco is sold is in ready made cigarettes and cigars. Tobacco is also sold in bulk for smoking in pipes or self-rolled cigarettes. Each of these forms of consuming tobacco has limitations for the consumer and in particular the consumption of bulk tobacco is not popular because of the manner in which bulk tobacco is consumed. Assembling a self-rolled cigarette or filling a pipe may create a hazardous situation or detract from the quality of the tobacco if performed with dirty or contaminated hands. Furthermore such action is time consuming and the tobacco is often wasted.
In addition to the above, tobacco is wasted when it continues to burn during protracted periods when the smoke is not inhaled. Such burning may also comprise a potential fire hazard and cause passive smoking. Also, once the cigarette or cigar has been consumed the resultant butt becomes unsightly and a potential hazard to children. With the pipe, the preparation and the need to carry both the pipe and bulk tobacco make pipe smoking relatively unpopular.
The present invention aims to alleviate at least one of the disadvantages set out above and to provide smoking apparatus which will be reliable and efficient in use. Other objects and advantages of this invention will hereinafter become apparent.
With the foregoing and other objects in view, this invention in one aspect resides broadly in portable smoking apparatus including: burning chamber, and mouthpiece through which smoke from tobacco burned in the burning chamber may be inhaled, the stem assembly being moveable from a stowed position adjacent the storage assembly to an operative position at which the mouthpiece is accessible and remote from the burning chamber.
The feeding means may include a plunger which may be biased to force tobacco from the storage assembly into the burning chamber which may be opened to the storage assembly by a suitable gate to permit the required charge of tobacco to enter the burning chamber or closed therefrom to permit the required charge of tobacco to be burnt. For this purpose the tobacco may be supported in the storage assembly in prepared charges adapted to be fed successively into the burning chamber. Alternatively raking means or the like may be supported in the storage assembly to rake tobacco from the storage assembly into the burning chamber.
Preferably however the burning chamber is supported in a chamber body which may be moved to position the chamber in a burning position at which the chamber or a portion thereof is exposed to atmosphere or a loading position at which the chamber communicates with the storage assembly. The chamber body is suitably formed of an insulating material or the burning chamber may be insulated to inhibit heat transfer therefrom. Furthermore the feeding means may be associated with the stem assembly in such manner that movement of the stem assembly actuates the feeding means to feed tobacco from the storage assembly into the burning chamber. For example the stem assembly could be connected to a scraper blade which when pivoted with the stem assembly scrapes a charge of tobacco from the storage assembly into the burning chamber and if desired the scraper blade could constitute a bottom closure for the burning chamber during use. Of course the stem assembly could be arranged independent of the feeding means and could pivot or be a removable plug-in stem assembly if desired.
Preferably the chamber body is supported rotatably within a chamber housing and is rotatable with the stem assembly from a stowed position at which the burning chamber communicates with the storage assembly whereby a charge may be fed into th
