Application filed December 13, 1905. Serial N o. 291,632.
To all whom 'it may concern: j
Be it known that I, HORACE N. MosnLEY, a citizen of the United States, residing at Elgin, in the county offKane and State `of illinois, have invented vnew and useful Improvements in PipeJointsrof which the fol-` lowing is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.
My invention relates tol improvements in pipe joints and more particularlyto that class of joints used for connecting the heating coils of steam heating apparatuszwith steam traps. l i
When steam heating apparatus, 4designed for heating railwaycars, has thesteam coils connected with the steamtraps, in extremely cold weather, the pipe leading Vfrom said coils to the trap, as well as thetrap itself,
is liable to freeze, and it 1s one of the ob jects of this invention to provide a pipe connection between the coils and traps having a valve whereby steam can be admitted to a jacket surrounding this connecting pipe `to thaw out both the pipe and the trap.
A further object of my invention is to provide an improved means `for preventing foreign objects from entering the Y steam trap from the coils, thus insuring the perfect working of the trap under all conditions. j
A further object `of my invention is to provide a device of this character which is of the same general size as the angle valves now in use, tothe end that a readjustment of the parts may be unnecessary l1n placing my device in the position the angle yalves occupy. This is accomplished by arranging in my device the inlet and outlet for the steam in the same relative positions, as are the inlets and outlets in the angle valves now in use.
I have illustrated the embodiment ofmy invention in the accompanying drawings, in which: j
Figure 1 is a longitudinalsectional view of my valve; Fig. 2 is a sectional view taken on line 2 2 of Fig. 1.
As shown in the accompanyingdrawings, t
my' device makes use of'a casing 1,.having a chamber 2 formed therein, which chamber` is adapted to communicate by the port 3 with the pipe or jacket 4. A valve 5 controls the port 3. This valve is of the usual construction having a screw-threaded stem provided with a handle 8, whereby the valve may be raised or lowered from the seat 9,
lto control the admission of steam from the chamber 2 to the jacket 4. The plug 7 is preferably screw-threaded into its opening 10, as shown. A second chamber 11 is formed in the casing 1, which communicates through the port 13 andconnecting pipe 14 with the steam trap.` A screen 12 is arranged in the chamber 11 and fits over the port 13 to prevent foreign objects from entering the steam trap. This screen is preferably cylindrical in form and is adapted to be insert-ed in the chamber 11 throughfan opening 15 formed in the top thereof. The lower end of the screen rests preferably on a seat 17 formed around the port 13 and the screen is held in position by the screw-threaded plug 1G through which passes the stem 18 of a valve 19 which when seated closes the port 13. Normally the valve 19 is opened and the same is provided to close the valve in case the apparatus become disarranged or when it is desired to removethe pipe 14 or disen- Patentednug. si, 1909.
6 adapted to be screwed into the plug 7 and sov gage the same from the steam trap. The
Vthe parts due to the jar of the train when in motion is effectually prevented. Steam may be admitted into the jacket 4 through the port V3. The chamber 11 is connected with the' steam supply through the port 23 by means of a suitable pipe 18a.
In operation, the valve 5 being closed and valve 19 opened, steam will pass from the port 23 to the chamber 11 through the screen 12, down through the pipe 14 into the steam trap, the screen 12 serving to prevent foreign particles fromescaping into the trap.
vIn event the pipe 14 or the steam trap becomes frozen,`the valve 5 may be opened by operating the handle 8 and steam will then pass through the port 3 into the jacket 4 around the pipe 14, heating said pipe and trap, and serving to thaw them out.
Y termed.. 1 i5 exhaust'port, a jacket secured to said casing and surrounding said pipe, a steam trap having a tapered end in threaded engagement withusai'd pipe, and lugs. extend-ing in- Vwardly troni said `jacket and arranged for engagement by said tapered end of said steam trap whereby a 2. In combination, a pipe joint casing having supply and exhaust portava pipe se- I cured to said casingand` leading Jfrom said exhaust port, a jacket secured to'said casing and surrounding :saidr pipe Vand having a bell-shaped portion at the lower end thereof,
Steam trap arranged in said bell-shaped portion of, said jacket andihaving a tapered e end in threadedengagement with Said pipe,
and lugs extending' inwardly from said jacket and arranged for engagement by said tapered endr ot said steam trap whereby `a.
.y wedge connection is formed.
3. In cQInbination, a pipe joint' casingv l having. a chamber with suppllyand exhaust Yse ports, al pipe secured to said casing and leading fremsaid, exhaust port, a jacket secured te said casing and surrounding said pipe and communicating with saidy chamber, a steam.
"trap hearing a tapered end in threaded engagementwith said pipe, and lugs extendwedge connection is j ing inwardly from said acket and arranged for engagement by said tapered end of said steam trap whereby a wedge connection is formed.
f 4. In combination, a pipe joint `casing A, having supply and exhaust ports, a pipe secured to said casing and leading from said exhaust port, a jacket secured to said casing and surrounding said pipe, a steam trap having a tapered boss at its inlet with which said pipe has threaded engagement, and lugs extending'inwardly from said jacket and arranged for engagement by said tapered boss whereby a wedge connection is formed.
5. In combination, a pipe joint casing havingl a chamber with supply and exhaust ports, a pipe secured to said casing and leading froml said exhaust port, a jacket secured to said casing and surrounding said pipeand having communication with said chamber, a valve for controlling the connection between said chamber and Said jacket, a steam trap having a tapered end in threaded engagement with said pipe, and lugs extending inwardly from said jacket and arranged for engagement by said tapered end of said Steam trap whereby a wedge connection is formed.
In witness whereof, I have hereunto subscribed my name in` the preeence of two witnesses.
