THOMAS A. SIVANN, OF BALTIMORE, MARYLAND.
FITTING FOR KITCHEN OR STAND BOILERS.
SPECIFICATION forming part of Letters Patent No. 426,150, dated April 22, 1890,
Application tiled October 4, 1889.
To all when?, t may concern.-
Be it known that I, THOMAS A. Swann, a citizen. of the United States, residing at Balti more, in the State of Maryland, have invented certain new and useful Improvements in Fit tings for Kitchen or Stand Boilers; and I do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appcrtains to make and use the same.
My invention is designed to materially reduce the cost of the constructive parts of kitchen or stand boilers and the expense of the plumbers time in combining such parts and setting up the device ready for use.
It is further designed to insure that the in duction or cold-water tube shall be provided by the workman with the proper vent-aperture to prevent the siphoning of the water from the boiler, so that a careless mechanic cannot leave the boiler in an apparently proper but really detective condition, which, when discovered by using the apparatus, can only be repaired at much inconvenience and expense, I accomplish these objects by providing a iitting of special construction, hereinatter particularly set fortlnwhich is adapted to be placed upon the market, purchased by the plumber, and used in connection with any kitchen-boilen In modern plumbing construction lead has to a considerable extent been superseded by iron piping, and by my invention the boiler is adapted to be readily connected with the latter system of piping, thus saving the expensive spuds and the couplings which have heretofore been generally used in connecting standboilers with thc water supply and dis charge pipes.
In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect without, however, limiting it to the exact details of construction, which, for the sake ot illustration, I have set forth.
In said drawings, Figure l is a perspective View of a kitcheirboilcr fitt in g embodying my invention. Fig. 2 is a sectional view of the same. Fig. 3 is a perspective view of a lit'n ting also embodying the invention, but of a larger size and slightly-'Imodied form,
Referring to the drawings, A indicates in dotted lines a portion of a kitchen-boiler, and B the induction or cold-water pipe of the same, which is situated within and extends downward from the top toward the bottom of the boiler for the purpose of causing the incoming cold water to be delivered to the lower end of the boiler and the hot water to be forced upward and to be drawn from the upper end of the same.
O indicates the iitting which embodies my improvements. It consists of a cylindrical tubular piece of metal-suoh as brasspret erably provided with an external hexagonal or eight-sided iiange o, by which it is adapted to be turned in securing it in place. Immediatelybelow said flange is out a screw-thread c', adapted to engage a corresponding thread cut in the top of a boiler A, and above the iiangc c thc iitting is provided with another screw-thread ci, by moans of which the proper connection with the water-supply pipe may be made. This thread o2 is not of that character employed in brass spuds and couplings, but is out to viit the threads of iron piping, thus adapting the ttin g to modern plu mbing construction.
At c8 the lower end of the fitting is reduced in external diameter and adapted to be readily passed down and into the boiler through the screw-threaded aperture, which is subse quently engaged by the thread c. At its lower end the portion ci" is provided with an internal screw-thread ci, extending for about three-fourths of an inch upward into the fiting, and which is adapted to be engaged by a corresponding thread upon the upper end of the pipe l5.
At a point justabove the thread c'l the iitting is provided with a vent-perforation c, which may be cast therein in the process oi' manufacture, by which the interior of the iitting is placed in direct communication with the upper part of the boiler, thereby preventinfr the siphoning out of the water by suction at the lower cud of pipe l5. IVhere it is left to the plumber in setting up the boiler to provide the pipe B with a suitable vent-orico it is often carelessly omitted (or this often occurs 'for the want of a suitable drill) and the apparatus left in a defective condition. It has oven been of not uncommonoccurrence IOC with the fittings heretofore employed that the insertion of pipe B into the boiler has been entirely omitted; but with my improved fitting, which is adapted to allboilers and is provided with the standard threads used in iron piping, these omissions will not occuigbut the apparatus will be readily set up in a perfect condition at less expense of material and time than has heretofore beenthe case.
The iitting C will be provided in different sizes, according to the capacities of the different boilers commonly used. When the fitting is of one of the larger sizes, it is preferableto form the screwthread c2 within the fitting, asv shown in Fig. 3, thus enabling the iron induction-pipe to be screwed directly into the litting. In this construction a further economy of material may be effected by doing away with any projection of the tube above the flange c, the internal screw-thread ozbeing cut below said flange and opposite to the thread c.
In using my improved fitting it is simply necessary to out a thread in the top plate of the boiler to correspond with thread c and to form upon the upper part of the pipe B a thread to correspond with the thread c4. The
' pipe B is then screwed into the lower end of the iitting and is passed down into the boiler, the lower end of the screw-thread c coming into contact with the outer surface ot' the top plate of the latter. By means of the nutshaped iiauge c the fitting is screwed down into place until said flange is brought tightly against said top plate. The iron piping may then be connected directly with the upper end of the iitting by means of the screw-thread o2.
Having thus described my invention, what I claim isl. A kitchen-boiler fitting having an external screw-thread adapted to engage the boiler, having at its upper end a second screw-thread adapted for the connection of the water-supply piping, provided at its lower end with a screw-thread adapted for the connection and support of the internal induction-pipe, and provided above the latter screw-thread with a vent-orifice adapted to place the interior of said fitting in direct communication with the interior of the boiler, substantially as set forth.
2.` A kitchen-boiler fitting consisting of a tubeprovided at its upper end with aliange, having below said flange an external screwthread, having also at its upper end an internal screw-thread, and having below said eX- ternal thread a reduced portion provided with a screw-thread for the connection of the internal induction-pipe of the boiler, and provided above the latter thread with a vent-aperture, substantially as set forth.
In testimony whereof I affix my signature in the presence of two witnesses.
THOMAS A. SVANN.
