CALKED SADDLE Chester V. Smith, Lancaster, Pa. Application October 3, 1950, Serial No. 188,182
1 Claim. l
This invention relates to a pipe coupling and more particularly to that type of pipe coupling known as a calked saddle, commonly used to bring a new line into an old established line.
The object of the present invention is to improve on the construction of the saddle so that it may be more easily and more thoroughly sealed.
A further object of the present invention is to provide an integral collar formed in one half of the calked saddle to serve as the feed line into the old established line.
It is a further object of the present invention to provide tits to support the upper half of the saddle at the juncture between the upper half and the lower half so that the upper half of the saddle is held slightly above the lower half to permit lead to freely ow and permanently seal the two halves of the saddle.
It is a further object of the present invention to provide a beveled groove at the juncture of the two saddles to serve as a means for introducing the lead in the sealing operation.
With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described may be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is shown in the accompanying drawing in which:
Figure 1 is a side elevation.
Figure 2 is a vertical cross section showing the established line pipe in position.
Figure 3 is a longitudinal cross section showing the established line pipe brokenly.
Figure 4 is a detail view of the juncture between the two halves of the saddle.
Figure 5 is a side elevation showing the saddle with a right angle juncture.
Figure 6 is a similar view showing the saddle with the juncture at 45.
The pipe coupling known as a calked saddle is used in connecting a new line to an old established line and is formed in two parts, the lower semicylindrical section 8 and the upper semicylin- Vdrical section 9. Integral with the upper section 9 is a hub l0 formed with a restricted depending outlet I I.
The lower half 8 of the saddle is formed with longitudinal channels I2 receiving the longitudinal lips I3 of the upper half of the saddle. Adjacent the lips I3 are tits I4 arranged in spaced relation, as shown in Figure 3, and serving to 2 support the upper half of the saddle slightly spaced from the lower half of the saddle to provide a comparatively equal space between the upper and lower halves of the saddle for the reception of a sealing medium such as molten lead.
The lower half of the saddle is provided centrally with a series of upstanding teeth I 5 which may be filed or chipped in the seating of the saddle around the old line pipe I6. The interior line of juncture between the upper and lower half is beveled at II to provide a groove I8 serving as a conduit for the molten lead and to insure the lead flowing throughout the entire length of the longitudinal juncture.
In use the old line pipe I6 is bored at I9 to provide a hole for the reception of the integral inlet Il of the hub I0. The upper half of the saddle is placed in position and the lower half slid onto the lips I3, filing or breaking the teeth I5 to provide a snug fit between the saddle and the old line pipe I6. A screw 28 is tightened to temporarily hold the two halves of the saddle in position. Calking 2i is tamped between the saddle and the old line pipe and molten lead is poured into the groove I8 completely filling the groove I2 and forming a seal between the upper half of the saddle and the lower half of the saddle which also effectively seals the saddle to the old line pipe. The flow of the molten lead so as to completely iill the groove I2 is insured by the tits I4 sup-porting the upper half of the pipe slightly above the lower half of the pipe to provide a channel for the now of the sealing medium.
The upper edge 22 of the channel I2 is bent inward toward the body of the pipe, terminating a slight distance from the pipe providing a slit 23 into which the molten lead may be poured when the saddle is used in a horizontal position.
Figure 5 shows the saddle formed with the hub at a angle to the saddle while Figure 6 shows a modification showing the hub at an angle of 45. Applicants improvements in the construction are the same in both of these modications and are directed primarily to the use of the integral inlet ange and the construction of the saddle to provide thorough sealing.
What is claimed is:
A pipe coupling of the calked saddle type, comprising upper and lower semicylindrical sections, the longitudinal edges of the lower section being formed to provide diametrically oppositelongitudinal grooves, lips formed on'thelongitudinal edges of said upper section slidably tting within 3 said grooves, a piuraiity of tits carried on the References Cited in the fle 0f this Patent under Surface of said lips and cOntaCting the Side UNITED STATES PATENTS of said grooves to preveriil Contact between the Number Name Date upper and lower sections of the saddle and to 5 867,169 Thomas Sept 24, 190,7 evenly space Jche lips of the upper section from 375,729 OBrien Jan. 7, 1908 the sides of the grooves of the lower section to permit the even flow of a sealing compound With- FOREIGN PATENTS in said grooves and about said lips to form a, Number Country Date sealing seat throughout the entire longitudinal 10 14,392 Great Britain June 15, 1915 extent of the grooves. 168,991 Germany Mar. 28, 1905
