PHILIP MUELLER, 0F DECATUR, ILLINOIS, ASSIGNOR TO THE B. MUELLER MANU- FACTURING COMPANY, OF DECATUR, ILLINOIS, A CORPORATION OF ILLINOIS.
Specification of Letters Patent.
Patented A11 8, 1911.
To (LZZ whom it may concern:
Be it known that I, PHILIP MUELLER, a citizen of the United States, and resident of Decatur, Macon county, State of Illinois, have invented certain new and useful Improvements in Service-Box Sections; and my preferred manner of carrying out the invention is set forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.
This invention relates to water distribution and more especially to that class of devices thereunder known as mains and pipes; and the object of the same is to produce an improved service box, or more especially a service box section adapted to connect the lower end of the standard service box to curb cocks of a variety of sizes.
To this end the invention consists in a short tubular section of the service box screwed to the lower end of the upper box body or section and screwed at its other end onto threads on the body of the cook, the lower section being shaped between its extremities as the respective sizes of the parts thus connected may demand.
The following specification sets forth an embodiment of this invention as illustrated in the accompanying drawings, forming a part thereof, wherein;
Figure 1 is a side elevation of the lower box section alone. Fig. 2 is a central vertical sectional view of the same. Fig. 3 is a vertical sectional view showing the invent-ion applied. Fig. 4L is a similar view to Fig. 3 but with a longer lower box section than shown in Fig. 3, the stem of the cock being squared or otherwise made for the receipt of a key; this lower section serves to extend the length of the service box when the pipe is a considerable distance below the surface of the ground. Fig. 5 is a vertical section showing a long lower extension of the box wherein the threaded collar of the cock is the same size as the threaded bell end of the upper service box body; the threads in this instance may be right and left. Fig. 6 is an elevation partly in section showing the several parts separated.
Referring to the said drawings, the letter S designates broadly the service box now in common use, which preferably has a bell mouth B at its lower end interiorly threaded as shown, and the letter C designates the curb cock having a handle or squared shank H, and also having an exteriorly threaded collar T around its body, which collar in the ordinary use of devices of this character fits into the threads at the lower end of the bell mouth B.
Coming now more particularly to the present invention, the box section forming the subject matter of this invention and best illustrated in Figs. 1 and 2 comprises a body 1 preferably flared a little at its lower end as at 2, and interiorly threaded at said end for a short distance as at 3 to fit upon the threads T of the cock C; and when said threads T are made in a variety of sizes according to the sizes of the cooks, the lower end of this section will be correspondingly shaped. By preference I provide a shoulder at on the interior of the lower section, which shoulder may be made in a continuous ring around the interior or may be formed in a number of lugs, and it is located sufficiently above the threads 3 to permit the latter to be screwed onto the threads T and yet no further than said shoulder as shown in Fig. 3. The upper end 6 of the lower service box section will, as shown in the several figures, be reduced in diameter to a greater or lesser extent as indicated at 6 and exteriorly threaded as at 7 to fit the interior threads within the bell-mouth B of the upper section. The shoulder thus formed by reducing the end 6 serves as a stop for preventing the lower section of body 1 from en- Y tering too far into the service box A. In Fig. 3 this improved lower section is shown as enlarging the size of the bore of the lower end of the service box so that a larger cock can be used within the lower sect-ion than would be possible within the service box itself.
In Fig. 4 a somewhat longer lower section screwed to the cock is shown as used with the upper box section; the opening for the reception of the cock C may be reduced or increased, as the size of the cock or the use of the upper box section demands, and yet obviously the key can be passed down through the service box body as in any other case, and the cock turned on or off if desired. Fig. 5 shows this longitudinal lower extension in use where the threaded collar of the cock is exactly the same size as the threaded bell-mouth B of the service body. It follows, therefore, that in the use of this improved lower section, where one is supplied with and fits the threads on the threaded collar of each cock and its upper extremity bears a standard exterior threaded end adapted to fit the bell-mouth at the lower end of the upper service box section, cocks of a variety of sizes and patterns can be connected with the standard service box. IV hen it is desired to extend the length of the service box, as when the water pipe is considerably below the surface of the earth, it is obvious that a somewhat longer lower section 1 could be used as shown in Fig. 4; or that a lowermost section 1 of usual length could. be screwed upon the cock, one or more similar sections having standard threads at both ends fitted upon the top of said lowermost section 1, and finally the upper service box section 5 screwed to the uppermost section 1 without departing from the spirit of the invention.
In Fig. 5, is shown an amplification of which this invention is susceptible, which I will describe as follows: In this connection the threads T are made left hand as well as those numbered 3 which engage them, and all other threads are right hand. In the assembling of parts, the lower section 1 is screwed onto the collar of the cock either before the latter is connected to the service, or while the trench is open and the cock unconnected and the service box S is screwed onto the threads 7, while there is an opportunity to hold the lower section against rotation. After the trench has been filled up, if it is desired to disconnect the service box S from the lower section 1, it can be done by a turn to the left applied to the service box. The flange a by abutting against the top of the threaded collar T prevents the section from rotating in that direction and hence resulting in unscrewing the parts at top of the lowermost section. By this arrangement it will be possible to remove the service box S from position without digging it up entirely and if it is carefully done, a broken box could be replaced more easily than by the constructions now in use. It is also shown here that the threaded collar T can fit into the service box proper as at B, the opening in the section 1 to receive the cock being the same as at B, provided the thread corresponds.
In Fig; 6 is shown a like connection as shown in Fig. 5 with a variation in sizes of parts; threads at B and 7 to be right hand and threads at T and 3 to be left hand.
hat I claim is,
1. In combination with a cock having a peripherally threaded collar, and a service box having an internally threaded lower end, of a connecting section between said parts shouldered at its upper end and terminating in a short neck of less diameter than said section, exteriorly threaded to connect with said service box, and interiorly threaded at its lower end to engage the threaded collar of the cock, said shoulder serving as a stop to limit the distance which said connection may enter the service box, and a projection within said connecting section near its lower end to limit the entrance thereinto of said threaded cock collar.
2. In combination with a cock having a peripherally threaded collar, and a service box having a bell mouth threaded in opposite direction to the cock collar, of a connect ing section between the two provided with an exterior thread on its upper end to engage the thread of the service box and an interior thread of opposite direction in the lower end of said connecting section to screw onto said cock collar, and abutting means within said section to prevent the rotation of the connecting section when the service box is turned to unscrew it from said connecting section.
In testimony whereof, I have hereunto subscribed my signature, this 21st day of March A. D. 1908.
