member, commonly termed an expansion' post, for regulating the escapement of air from the radiator. X
The principal objects of the present invention are to eliminate the separable member which is usually'providedfor the purpse of forming a lower abutment for the expansiompost; to4 eliminate the configuring of the interior 'of the valve casing for the purpose ci providing an abutment for the lower end of the expansion post; and to pro vide an abutment for said lower end of the expansion post in a manner different from those above enumerated.
The invention further relates to the features of construction and' to the combination of parts hereinafter described and claimed.
In the drawings, Figure 1 is a longitudinal section of an air valve constructed in accordance with the present invention; Fig.
2, a view similar to Fig. 1, showingY the eX- pansion post and the nipple which is secured to the upper end of the return pipe, in elevation; and Fig. 3, a view similar to Fig. 2, showing a modified form of upper abutment for the expansion post.
In the art to which the present invention relates, it is customary to employ a member known as an expansion post, which is susceptible to thermal changes; and this eXpansion post is located in the interior of the valve casing and lies between upper and lower abutments. It has heretofore 'been customary, so far as I am aware, to either form a 'separable piece which provides an abutment for the lower' end of the expansion post, or to configure the interior of the casing so as t0 have a portion of its inner walls provide said abutment. In the present invention, the abutment is formed in a manner diierent from either of the two methodsV heretofore described.
Referring to Fig. 1, the device comprises a casing Il, provided with the ordinary nipple 5, adapted to be attached to the radiator;
andthe casing is further vprovided with the usual cap-piece GsCreW-threaded to its upper end. Screw-threaded. to the lower end of the casing isa coupling orv union nut q7, which connects av nipple or collar 8 with the casing. Said nipple or collar is adapted to be secured to the upper end of the Areturn pipe, and when the valve is placed in operative position, this nipple becomes, in fact, the Vupper end of the return pipe, since it is locked thereto. The upper end of the nipple, as will bev clearly seen from Fig. l, is
vconfigured to provide an inwardly tapered opening 9, which forms a seat or abutment for the tlocked end 10 of an lexpansion post 11. It will be seen from the drawings that the expansion postis in a free condition within the casing; thatjis, it is not positively attached to any other portion of the valve mechanism.
It will, of course, be understood that the upper end of the nipple is shown as being provided with an inwardly tapered end, because of the fact that the Aexpansion post in the form illustrated` has its endsl of a tapering coniguration. .The particular oonfiguration of the upper end of the nipple and the lower end of the expansion post shown isnot the only form which could be lemployed in-oarrying out the present invention. It may be stated, as a general fact, that the upper end of the nipple must be configured in correspondence to the contiguration of the lower end of the expansion post, at least in such a manner as to give a substantially firm and rigid bearing for said lower end. The upper end 12 of the expansion post, is adapted to seat against a ring 13; and the expansion post recedes and advances from this ring 13 to cont-rol the escapement of air from the radiators, as is well known by those skilled in the art.
In Fig. 3 the construction is exactly similar to that shown in Fig. l, save that the' ring 13, in place ofbeing open at itsupper end, is closed by a web 16. By providing an abutment for the lower end of the expansion post in the manner described, the
separate part which is commonly employed cult, if not impossible, when"theinner portion or' the casing is of a conguration to provide an abutment for the lower end` ot the expansion member.
l claim:
l. In an air Valve for radiators, the ,com bination of a casing provided with an inlet for connecting it to the radiator, an expansible member loosely held wit-hin the casing.
Y,provide a seating face for the lower end orl the expansible member and furnishing a lower abutment for the expansible member, said member being separated and loosely held in position between the seating facesl ofthe upper and lower abutments, the lower open end of the valve casing being of a size to permit the expansible member to pass freely therethrough, a coupling nut for attaching the nipple to the casing, the upper and out-er edge of the nipple bearing against the lower inner edge of the open lower end of the casino' making a steam and air tight joint at this point, substantially as described.
2. In an air valvefor radiators, the comopea et this patent 'may he obtained for bination of a casing provided with an inlet for connecting it to a radiator, an expansible member 4loosely held within the casing, an upper abutment adjustable in and detachable from the casing and having a seating face for the upper end of the expansible member, a freely detachable coupling nip- 'ple having an opening therethrough contracted intermediate its ends, the wall of said opening below said contraction being screw-threaded, the wall of said opening above said contraction being configured to provide an outwardly flaring funnel-shaped` opening providing a seat Yfor the lower end of the expansible member and furnishing a lower abutment for the expansible member, said member being supported and loosely held in position between the seating faces of the upper and lower abutments,
the
lower open end of the valve casing being of f a size to permit the expansible member to pass freely therethrough, a coupling nut for attaching the nipple to the casing, the upl per outer edge of the nipple bea-ring against the lower inner edge of the open lower end of the casing making a steam tight joint at this point; substantially as described.
