BATI-LGABINET HEATER.

Specification of Letters Patent.

Patented Sept. 11, 191%.

Application filed October 21, 1916. Serial No. 126,932.

To all whom it may concern Be it known that I, MAXWELL M. J ONES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bath Cabinet Heaters, of which the following 1s a specification.

The present invention relates to an improved heater or stove designed for use with bath cabinets.

It is common practice to employ within a bath cabinet a heater or stove which is operated until the air within the cabinet has been suiflciently heated, or charged with the requisite amount of vapor. After the bath treatment has continued awhile and the temperaturehas risen considerably, the patient then extinguishes the flame. It is usual for the patient to occupy a sitting position in the cabinet and to be wholly inclosed within the cabinet, only hishead remaining outside. Accordingly the manipulations necessary to extinguish the heater flame are made under difficulty, and are effected through the sense of feeling alone. It sometimes happens the patients hand, leg, or foot comes into contact with the heater resulting in painful burns, or possibly an upsetting of the stove, so that the cabinet is liable to be set on fire.

Such dangers and diliiculties as I have mentioned are entirely overcome by the present stove. For the purpose of providing an improved construction, my invention embodies means for preventing tipping or upsetting of the heater, means for protecting the patientwfrom contact with the heater, means conveniently and positively operated for extinguishing the heater flame, and means permitting the heater parts to be readily disassembled for purposes of packing or shipping. These and other objects of my invention will more fully hereinafter appear from the specification and claims, and are clearly set forth in the accompanying drawings, in which Figure 1 is a sectional view through a bath cabinet showing a stool and heater operatively positioned therewith;

Fig. 2 is a perspective view of the heater 1 in its entirety;

Fig. 3 is a perspective view of the upper portion of. the heater, exhibiting the guard frame and flame extinguisher;

Fig. 4C is a side elevation of the several heater parts, the guard frame being shown as removed from the base, and the pan as being removed from the guard frame;

Fig. 5 is a plan view of the guard frame with burner in place; and

Fig. 6 is a sectional detail showing the locking connection between the guard frame and the base.

In Fig. 1 I have represented a bath cabinet 7, the walls of which inclose a chamber 8, over which is a cover 9 provided with a central opening 10 adapted to fit around the neck of the patient. Within the cabinet is a stool or chair 11, beneath which may be placed the heater or stove 12 which forms the subject matter of the present invention. Between the heater and stool a chain or other suitable connection 13 is arranged, being hooked, if preferred, as at 14: to the stool. By this means, the patient is enabled to extinguish the heater flame at will, in the manner to be presently described.

The present heater comprises four prin cipal elements, each of which is separable from the others, to-wit, a base 15, a guard frame 16, a burner 17, and a pan 18. l/Vhen operatively assembled, the parts of the heater will occupy the relative positions shown in Fig. 2, but when disassembled may be separated from each other in the manner shown in Fig. 4.

The heater base 15 is provided with generally cylindrical walls 19, the lower portion of which is flared out or flanged as at 20. The base is closed on its upper and lower sides to provide a chambered con struction, a central threaded opening 21 being formed on the upper side of the base. Into this opening may be threaded a cap 22 having an out-turned flanged portion 23 engageable by the fingers. By means of this cap the base chamber is entirely closed.

The guard frame 16 is formed with a ring 24 on its bottom, over which the flanged portion 23 of the cap 22 may lie to hold the guard in place upon the base. Extending radially from this ring are arms 25, preferably four in number, which take an up ward turn as at 26 and support a ring 27. Extending outwardly and upwardly from the ring 27 are arms 28 preferably four in number, which carry at their extremities an enlarged ring 29. Other arms 30 extend upwardly and inwardly from the ring 29 and support at their extremities a top ring 31. The form of guard frame just described adapted to fit Within the lower portion of the frame where it is supported upon the arms 2-5 and held in place by the arms 26 and ring 27. ithin the burner may be placed asuitable absorbent material covered,

if'ile'sired, by a screen or mesh 32. Alcohol or other suitable fuel may be burned to supply the necessary heat. I have shown a reducer 33 consisting of a ring adapted to cover a portion of the top surface of the burner, and this may be used, if desired, to reduce the size of the flame.

Means are providedalso for extinguishing the flame andconsists of a disk 34 of size andshape corresponding to the top of the burner and adapted when seated thereon to smoother the flame. This disk is loosely carried upon an arm 35 looped as at 36 to bear against the disk when the same is in central position upon the burner. The arm 35 is coiled as at 37 arounda pintle 37 eX- tending between the rings 29 and31 of the guard frame, from whence it projects to provide a lever portion 38. This lever is bent at one place in the form of a loop 39 and elsewhere, as at 40, is formed with another bend, its extremity 41 being shaped to provide an eye 42 to which a chain or other suitable connection may be attached. l/Vhen in the position shown in Fig; 3, the bend 40 of the lever 38 is arrangedto engage with the ring-29 of the guard frame to limit further movement of the disk away from the burner.-- hen, however, the chain 13 is pulled to swing the lever 38 around upon the'arm 30 which serves as a pivotal mountingtherefor, the disk 34: is brought by a swinging movement directly over the burner so as to extinguish the flame. lVhen the disk has advanced to final position the loop 36 bears-upon the disk in such a manner as to hold it tightupon the burner. The loop 39 is arranged to Contact with a member 13 positioned upon the ring 29 ofthe guard frame, to limit further movement of the disk. In this manner, I have provided a positive and ready means for effectively ex tinguishing the heater flame, and operable bymeans of the chain 13 which may be conveniently secured to'thestool as at 14, in the manner shown in Fig. 1.

The pan which is of cylindrical formation is formed with an out-turned flange 19 on its upper edge. It is intended that this pan maybe supported upon the top ring 31 of the guard frame, the flange 19 resting directly upon'th'e ring. In this manner, the pan is supported directly above the burner and at a suitable distance, so that the flame will quickly heat to a high temperature the liquid contained in the pan. The vapor arising from the liquid thus heated may readily disseminate throughout the cabinet. As it is common to heat medicinal preparations in the use of bath cabinets, the ad vantages of this construction are clearly apparent.

The operation. of the present heater should readily be understood from the. fore going description. The base should be filled with sand or other suitable substance which will provide a ballast for the heater. For purposes of shipment, however, the base should preferablybe empty. By means of the weighted base, the heater is held securely in position upon the floor, and is protected against accidental tipping or upsetting. The cap used as the connecting medium between the guard frame and the base may be readily applied. It forms a closure for the base such as to prevent the loss of the ballasting material, whether it begranular, liquid, or otherwise. The guardframe con struction is both simple and-strong. If the ring 29 be of generous diameter, it is suificiently removed from the flame of the burner to remain comparatively cool. At the same time it will protect any object from harm which comes into dangerous proximity to the flame. The guard also serves as a support aiiclmiounting for the extinguisher which, as has been explained, is

readily and conveniently operatedlby such means asthe chain shownin Fig. 11
