JACKET 0R HOODl FOR USE IN CONNECTION WITH THE EXHAUST-HEADS 0F HOT-WATER URNS 0F CDFFEE APPARATUS.

Patented June 26, 1906.`

Application ned July 7,1905. serial No. 268,679.

To all whoml 'it may con/cern.;

1 3e it known that I, ELIE J. MONEUSE, a c1t1zenlof the United States, residing at New York, 1n thecounty of New York and State of New York, have invented certain new and useful Improvements in Jackets or Hoods for Use in Connection with the Exhaust-Heads of Hot-Water Urns of Coffee Apparatus, of which the following is a specification.

This invention relates to improvements in .the pressurein the water-urn reaches the Y point where it blows off, thus preventing ac'- cident by scalding and inconvenience in at# tending to the apparatus.

A further object is to so construct the device that the steam when it blows off will be condensed in the head or jacket around theexhaust-head and be drawn olf gradually through a pi e or other suitable means for conducting t e water to a suitable point or outlet or waste. Y

A still further object is to so construct the top of the hood that it will aiford absolute protection for the air-inlet valve of the exaust-head, and thus render it practically impossible to close said valve and prevent they necessary amount of air from passing into the water-urn when the contents of said urn, or a part thereof, either steam or water, is removed, the air-supply being necessary when theconnection between the water-urn l and colee-urn is openedl v A It sometimes happens through carelessness'or lack of understanding of the a paratus that accidents occur .in whichl t `e attendants 4are scalded through the excessive exhaust of hot water and steam, due to the fact that the exhaust-head exhausts into the open air, and the hood about to be described is designed to prevent this. Further, the

Water-urn is sometimes injured and indeed or openin dental or careless Stoppa e of the air-inlet valve` ofthe exhaust-hea which stoppage prevents the admission of air to the urn to replace the water in said urn as it is being drawn off, and the peculiar construction of the top of the hood in the present invention is designed to protect the air-valveand render its stoppage practically impossible.

sometimes collapsed by reason of the acci--V With the above objects in view, and others looking to the general improvement of .devices of this character which will become apparent in the course of the following description, I will now proceed to describe the device in detail and point out the features of novelty in the appended claims.

In the drawings, Figure 1 shows a side elevation of the water-urn with my' improved device attached thereto, showing the water connections that lead to the coiee urn or urns, said urns being omitted,.since they have nothing to do with the present invention. Fig. 2 is a central vertical section'of the exhaust-head and my improved hood or `jacket surrounding the same; and Fig. 3 is a erspective view of the removable top of the 0o showing more clearly the manner, of perforating the same.

Referring to the drawings, the numeral 1 represents the water-urn of usual construction, and 2the exhaust-pipe connectedwith the steam-space of said urn, to the upper end of which pi e is secured the exhaustead 3, having gui ed in the web 4 therein the exhaust-valve 5, which is beveled, as indicated A yat 6, and normally resting in a corres onding seat 7 in the upper part of the head). vThis valve has a central opening (indicated by the numeral 8) for the admission of air through said openin to the water-urn. Thiso enin 8 is norma y closed by a valve 9, orme with a stem 10, which passes through a screw-plug 11 in the lower end of the hollow extension 12 of the valve proper, 5, and around the stem of the valve 10 is va light spring, which is interposed between the airvalve head 9 and the screw-pllug- 11 for the obvious purpose of keeping t e valve-head 9 normally seated. Through the hollow extension 12 ofthe exhaust-valve is an aperture 13, which permits the air when the valveead 9 is moved from its. seat to ass into the urn.' The screw-plug 11 has a ateral ange or ledge 14, between which and the web 4 is interposed a s ring 14', suitably tensionedv and holding t e exhaust valve seated under normal conditions. The construction just described, which involves the exhaust-head, is common in apparatus of this char^cter.

In ada ting my invention to the described exhaustlead I provide a screw-nut 15, work ing on a thread on pipe 2, and provide a acking-ring 16, between which and the ower hexagonal flange 17 of the'eXhaust-head casting is clamped the inturned flange 18 of the condensing hood or jacket 19'. This hood or acket extends considerably above the ex.-

aust-head, as shown, and is provided near,

its bottom with an outlet-opening 20, internally screw-threaded for the reception of a drip-pipe 2l, through which the water the result of the condensation of the steam and other water in volurnegpasses to any suitable point of outlet or waste'.

The hood is provided or, rather, constituted in part, by a removable top 22, formed with a depending flange 23, provided, preferably', with two oppositelydisposed rectangular slots 2li, which in conjunction with the short laterally-extending pins 25, serve to form a bayonet-joint, by which means. the top is held rm'ly in place in such a manner as will permit its easy removal by silightly turning the same whenrit is desired to have access to the inside of the hood for cleaning or other purposes. Near the outer yperihery of the top l provide a circular series o small openings 2G, primarily for the purpose of admitting air to the' hood when necessary and forl the secondary purpose of permitting the escape of steam should the volume of exhaust reach the point where such outlet is necessary. V

Depending from the top on the inside thereof, near the line of perforations 26, and surrounding the exhaust-valve of the eX- haust-head is a circular continuous flange 27 When water and steam is blown ofit is received within this flange, the steam being condensed and the water deilected downward around the exhaust-head to the lower part of the'hood or jacket, from whence it passes through the drip-pipe. The top or cover is preferably formed with a doine 28,which, aside trom bei-ng ornamental, has utility, its utility consisting in that it prevents a towel or other article which may be carelessly thrown over the apparatus from stopping up the perforations 27 and insures at all times the admission of air to the air-inlet valve of the eX- haust-head, the great number and diil'erence in location oi" the perforations- 27 also tending to the accomplishment of this object.

The construction of the hood or jacket is scacco s-uch that it can be readily attached to the exhaust-head now commonly used upon urns of this character.

When through neglect or otherwise the pressure in the urn exceeds that desired or required, the pressure will lift the valve 5 and the water and steam will be projected with force against the top of the jacket or hood within the space inclosed by the flange 27 and will be deflected downward on all sides ol' t-he exhaust-head and will pass out. of the drip-pipe without danger, injury, or inconvenience to the attendants, and at the same time pro er indications will be given that prompt t e attendants to take further recautions to prevent further blowing oil othe water and steam.
