PATENT TOBACCO-PIPE.
SPECIFICATION forming part of Letters Patent No. 727,789, dated May 12, 1903.
Application filed October I, 1901. Serial No. 77,843. (No model.)
To all whom it may concern.-
Be it known that I, MAX FRANZ HAHN, railway contractor, a subject of the German Emperor, residing in the city of Oharlottenburg, in the Kingdom of Prussia, German Empire, (post-office address at 4 Wielandstrasse, (Jharlottenburg, care of Eugen Folkmar,) have invented a certain new'and useful 'lobacco- Pipe, of which the following is a specification.
This invention has reference to improvements in tobacco-pipes, and it provides means whereby the burning portion of the tobacco is always left exposed and open to the access of the air.
When compared with the tobacco-pipes now in use, my invention presents a number of important advantages, of which I may mention the following: The unused tobacco, unless it has already undergone the action of dry distillation, is always kept pure'and fresh, as any transmission of the heat of combustion to this part of the tobacco is avoided. Thus it is obvious that even if the pipe should go out several times this will do no harm to the flavor of the tobacco, which will be the same as in freshly-charged pipes after the pipe is lighted again. Furthermore, the pipe as constructed according to my in vention will retain the fire as long as an ordinary cigar,
inasmuch as the zone of combustion is out-- of construction on the accompanying drawings.
Figure 1 is a vertical section, Fig. 2 showing a modification, in vertical section also.
The body of the pipe consists of a tube a, preferably cylindrical, which serves for the reception and for protecting and feeding the plug of smoking-tobacco b. The tube a is open at the top, while at the bottom it is closed by a cap m,which may be attached by bayonet-j oint or in any other suitable manner. A Washer p is inserted between the cap and the tube a for tightening purposes. The upper open end of the tube at is covered by the vaulted cap or'burner-head f, which is provided with a conically-shaped opening it for the passage of the smoking-tobacco plug. For brevitys sake I will call this opening in the following specification the burner-cone wherever this opening is referred to.
' '5 is the cover proper, which is detachably connected to the burner-head or top piece f and which closes the top opening of'the pipe, while it also serves at the same time for the collection of the ashes. lateral tubing d is attached, which communicates by a suitable opening with the tube a and serves for the escape of the smoke and which is deepened at e to provide a chamber To the tube a the or sink for the accumulation of moisture or a liquid particles in general.
gis a gasket for tightening the joint around the upper part of the tube a. Between the top part of the tube a and the lower rim of the burner-cone is a space Z, which in the following specification will be referred to as the burner-slot. This opening or burner-slot l is intended, first, to allow the escape of the smoke into the smoke-chamber c, the gases flowing in the direction indicated by arrows in the accompanying drawings. Then, second, the burner-slot allows a regulation of the progress of combustion, inasmuch as by adjusting the height of the said slot it is possible to accurately determine how large a quantity of the tobacco contained in the plug is to be subjected, first, to the combined action of heat and moisture, whereby it becomes softened and assumes a plastic condition suitable for feeding it into the burner-cone by the pressure of the spiral spring supporting the tobacco, and, finally, for introducing the thus-prepared tobacco into the zone of comimmediately in front of the burner-slot soon becomes plastic, while the remainder of the plug remains hard and solid, as it is protected by the tube a. The plastic portion, however, is immediately forced through the burnercone and into the zone of combustion. Third, in case of particles of tobacco being rubbed oif from the plug during its feeding forward the burner-slot will cause them to drop to the side, so as not to interfere with the draft of the pipe. Fourth, then the burner-slot prevents the transmission of the heat of combustion upon the tube a.
The burner-slot and burner-cone herein referred to are proportionate to the extent of the zone of combustion. This is caused by the bottom part of the zone of combustion being always outside of the tube of the pipe, the relation being the same as in the case of the bottom part of the flame in keroseneburners. The burner-slot operates to induce the softening of a certain amount of tobacco. If the height of the burner-slot were excessive, too large a quantity of tobacco would become softened, the burner-cone would fail to distribute the excess of soft tobacco thus produced, and it would not pass into the combustion zone. The tobacco would then also be forced to some extent into the cavity of the smoke-chamber 0, immediately adjoining the burner-slot. In this case the pipe would refuse to work, as it would become choked up. Then, on the other hand, if the lower part of the zone of combustion is situated too high above the upper edge of the burnercone while the quantity of plastic tobacco is in condition to pass through the opening of the burner-cone the pipe will also refuse to work, because the air which is sucked in does not enter the zone of combustion. It is obvious, therefore, that the shape of the burnerslot is essential for the position of the zone of combustion and for the normal operation of the pipe, and it is evident that if the size of the burner-slot is not hearing the proper relation to the burner zone, or, inversely, the zone of combustion will be displaced and imperfect or irregular combustion and waste of tobacco will ensue.
The shape of the burner-cone his governed by the following two requirements: First, the burner cone has to segregate the entire amount of the softened tobacco, and then it has to deliver it to the combustion zone; second, the dimensions of the burner-cone must be such that the quantity of tobacco fed from below into the burner-cone will operate to keep the lower end of the zone of combustion constant and above the upper rim of the burner-cone, just as the flame of a keroseneburner is kept above the upper rim of the burner-that is to say, the zone of combustion is situated entirely in the open air, so to speak, and not at the inside of the pipe. The following advantages are obtained by this arrangement: (a) The pipe will keep the fire as long as an ordinary cigar and without the necessity of the smoker sucking constantly at the mouthpiece of the pipe to keep it burning; (b) by this arrangement all the fine flavor and taste of a superior grade of tobacco are retained; (c) furthermore, I am enabled to use in my improved pipe any kind of cigar-tobacco, which heretofore could not be utilized in pipes. All these kinds of tobacco may be smoked in a pipe constructed according to my invention and will afiord great enjoyment and yield a fine flavor to the smoker.
The device described operates as follows: In order to fill the pipe, the cap on is detached and the spring 70, which is preferably attached to the cap m, is pulled out. Then the plug of smoking-tobacco is introduced from below into the tube a, and after the reinsertion of the spring and the closing of the cap m the plug is forced against the burner-cone h. (Compare also Fig. 2 of the drawings.) The pipe is then ready for use and is lighted at the top.
In Fig. 1 the plug of tobacco is shown partly burned up already. Part 01 of the plug is already converted into ashes while part 0 is still burning. q is the softened plastic part of the plug which has become segregated in the burner-cone. Fig. 2 shows the plug of tobacco intact and in position ready for immediate lighting. As soon as the heat radiating from the incandescent zone 0 and the moist vapors contained in the smoke have reached the upper part of the tobacco-plug they act to soften the same, and after this part has become plastic the spring 7:; forces the softened tobacco through the burner-cone and into the zone of combustion. The feed of the tobacco becomes very regular and in proportion as tobacco is consumed in smoking. If the smoking is discontinued, the pipe will go outwithin a few minutes. It appears from this that the smoker enjoys all the pleasure and flavor of a freshly-filled pipe until the said plug is perfectly used up, inasmuch as the gases of combustion, as shown in the drawings, do not penetrate through the unburned port-ion; but they are carried off latorally and around the pipe.
Fig. 2 shows a suction smoking-pipe embodying my invention; but it is obvious that the invention may be applied to other styles of pipes as well.
What I claim, and desire to secure by Letters Patent of the United States, is-
1. In a smoking tobacco-pipe the combination with a double-walled bowl and means in the lower part of said bowl for automatically feeding the tobacco, of an upwardly-tapering head attached to the outer walls of said bowl, an end opening in said head of smaller diam eter than the inner diameter of the bowl, an annular passage between the rim of the inner walls of the bowl and the base of the inwardly-tapering head and a lateral eductpipe in connection with said passage.
2. In a smoking tobacco-pipe in combination with a bowl and a lateral educt-pipe, an
inner casing or receptacle integral with said bowl and of smaller diameter and reaching below the bottom of said bowl, a conical 11pwardly-tapering open top attached to the rim of said bowl above and at a distance from the rim of said reeeptacle'or inner-casing and an annular passage between the bowl and the inner casing and of substantially the height Witnesses: W LDEMAR HAUPT,
HENRY HASPER.
