Specification of Letters Patient.
-lpplioatioii led October 19 ,1 N905." Serial No. 288,546. h
T all who' it may concerni-A 'I ,Be it known that I, WILLIAM` P. FIREY, a
oke, in the county of Roanoke 'an State iof vVirginia, have invented certain new and'useful mprovementsin- Cores, of which the vfollowing is a specification. f
IM invention relates to mol in g ipe-joints. l The o ject of .myuinvention is to provide means whereby an vunskilled operator may be enabled to obtain more uniform results and to economize time andmaterial.
. Itis a furtherob'ject of my invention to provide 'a paratus for molding pipe-joints which wil enable the material of which the HApipe is made to be fused with the joint-formi ing material without the pipe losing its shape and permits the rapid removal of the core of thel apparatus by theliquid carried bythe pip. r I
ith these and other objects in view the present invention consists'in the'combination and arrangement of parts, as will bev hereinafter more fully describedh shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the sco e of the claims without departing from t e s irit o r sacriicing any of .the advantages of t e invention. v
In theaccompanying drawings I have illustrated one complete example of the physical embodiment ofthe invention.
' In the drawings,- Figure 1' is ahorizontal section of my improved. sectional molding the core. Fig. 3 is a top planview of a shell used toform the mold when it is desired to permanently retain the shell over the joint. Fig.'4 is an end view of the complete removablemold shown in Fig. 1. Fig, 5 is an inside view. of the separate clampingplates used with--the shell of Fig. 3. l
'Referring 'to the drawings, 1 and 2 are the adjacent ends of the pipes to be joined. In the abuttin ends of said pi es 1- and 2 vand lying parta l in each of sai pipes is inserted a core 3, o soluble material, having a passage 4 running longitudinally therethrough,
said core being ada ted `to retain the shape pipe is heated to fusingpoint. 5 is a metal sectional shell portion the open ends of which are ,a'pproximlately'l of the 'same apparatus for' apparatus in one form. Fig. 2 is an end view' )diameter as bf the ipes to be joined, the
fsaidy ends bein of less iameter than the central portio11 ,`t ereby allowing a s ace 6' between theinner' wall of the shel and the `Patented; July ai, 190e;
pipes into which is poured the molten metal or `so der through an aperture yin -the shell.
The shell 5 is formed in two sections or halves having at eacli end the integral sectional -clamps 8. The sectional-mold is adapted to: be, held in position over the, pipe ends by bolts 9, passing through holes in lu s1() lof the clamp ends. This form of mol -is used when it is desired to use only vthe molten metal or solder. to complete the oint, the
shell lportieri being removed after t e molten meta template the use of the shell as a permanent retainer over thev j oint. an integral shell 5 vis used provided with an the joint, as in Fig. 1, and secured by` bolts 9 and molten metal pouredfthrough the o ening in the shell portion. After the mo ten metal hasset, the two sections ofthe moldV are removed, leaving a -solid and durableA joint. `In the modified form, the shell 5 be-v In this constructio'n has set; but in someinstancesI conparts of the sectional mold are placed around I' ing placed'on one of the pipes, core 3 is in!" serted the proper distance in the end of said pipe, and thcother pipe is placed in position 'on the outsideof the rojecting parts of the The. shell is tiien' slid into position over thel joint and the clamps 8 are bolted around the pipe irmlyfagainst the ends .of
IOO
the shell. The mold bein in position, molten metal or solder is poure through the aperture' 7 into the annular chamber 6 between the pipes and shell. As soon as. the solder has set, the clamps are removed, leaving .the shell firmly secured to the pipes. When the pipes are put into service, the li uid assing through passage 4 will q uickly -isso vethe saline core and leave the interior of the pipes unobstructed. f
It will be observed that the clamps and saline core Will prevent the pipes losing this IIO 75 o en1ng7 for pouring the molten metal. The
Shape should the pipe-metal fuse, and at the Smie time the core piesents .no permanent obstruction te the liquid en riied by the pipes. The metallic, .Qliell when lefty on the joint, be sides forming tbe mold lor )lie molten metal, tends to naturally strengthen 'flie joint.
Havii'ig thus described my invention, what lele-im asuovel, and (Alesiuie lo Secure by lieb ters Patent., is-
