INSERTIBLE FITTING FOR SOIL-PIPES. d

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed April 3, 1905. Serial No. 253,606.

To LZ whom it may concern:

Be it known that I, WILLIAM VANDERMAN, a citizen of the United States, and a resident of VVillimantic, in the county of Windham and State of Connecticut, have invented a new and Improved Insertible Fitting for Soil-Pipes or the Like, of which the following is a speciiication.

My invention relates more especially to the class of devices used in the plumbing of buildings; and the object of my invention` is to proplace.

vide a device by means of which a section of pipe may be readily removed when desired and a new section supplied to take the place of the removed section; and a further object of the invention is to provide means for inserting the section of pipe and firmly securing it in place. A form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a view, partly in section, of part of a line of soil-pipe, showing the application of my invention andbefore the parts have been secured in place. Fig. 2 is a similar view showing the pipe-sections secured in position. Fig. 3 is a detail View showing the thimble in side elevation as applied to the end of a pipe and before it has been secured in Fig. 4 is a top view of the same. Fig. 5 is a detail view showing a modified form of thimble. Fig. 6 is a top view of the same. Fig. 7 is a detail view showing another modication of the invention. Fig. 8 is a view in section through the ring shown in Fig. 7. Fig. 9 is a view showing the application of the latter-described form of the invention.

It often becomes necessary in a building to remove a section of soil or other pipes, as for the purpose of supplying a branch or where a section has become defective. In the older methods several sections of the pipe were disturbed to accomplish this result, and to obviate this objection various means have been devised. Such means, however, are objectionable from the fact that more or less space is left between the abutting ends of two sections with a result that the joint is not as strong and durable as would be desired.

By the employment of my invention 1 have provided means for extending a section of pipe after it has been placed in position, so that a section .may be removed and renewed, land by means of the extension, which forms practically an integral part of the section of pipe, the ends of the two sections are, in effeet, brought close together, abutting against each other, so that the resultant joint is, in effect, practically as strong as when the line of piping was first constructed.

[n the accompanying drawings a portion of `a line of waste-pipe of a building is illustrated, including a portion 1 and a portion 2. These when the line of piping is orginally formed are joined by a section similar to those illustrated at l and 2. It is when such a section is removed for any purpose whatever that my invention becomes applicable. It will of course be understood that the improved insertible section may be plain-that is, free from branches or Ts or may include such elements.

My improved insertible fitting includes as the essential elements an insertible section 4 and an extension-thimble 9. This insertible section is provided with a spigot end 7 for engagement with the section 2 of the main and has an elongated hub for the reception of the thimble 9. This extension-thimble is used for the purpose of extending a section 3 of the line of piping, the spigot end 6 of which is inserted in the hub 8 and elongated, as by means of the thimble 9. This section 3 of the pipe is of the ordinary construction, having the spigot end 6 and the hub end 5, as used in the remainder of the line of piping. l

It will be understood that in furnishing my improved insertible fitting the new construction consists merely in the insertible section of peculiar construction an-d the thimble, the remaining parts being of old and well-known construction.

The thimble 9 is adapted to tit closely about the spigot end of the section 3, and the thimble may be formed in sections, as shown in Figs. 3 and 4 of the drawings, although such construction is not indispensable. The lower end of the thimble is constructed to closely fit the spigot end 6 of the section 3 of the line, and a space 10 may be primarily left between the inner surface of the upper end of the thimble and the outer surface of the section 3, although this is not essential to my invention. The construction of the thimble IOO IIO

bodied'in the construction means for extending one of the sections of the line of piping, said extension being adapted to closely fit the end of said section, there being also means to receive and provide for extending said section.

In placing my improved fitting in position the thimble is placed about the spigot end of the section 3, and said end and the thimble are inserted in the elongated hub 8, as shown in Fig'. 1 of the drawings. The thimble rests upon the shoulder 11, and the upper section is extended or moved upward to the position shown in Fig. 2 0f the drawings. Oakum is then packed into the hub 8 about the thimble, as shown at 12 in Fig. 2 of the drawings, this oakum being packed in any well-known manner. In' this operation the upper end of the thimble. 9., especially where the space 10 is present, is forced tightly against the outer surface of the section 3. The thimble may be so constructed that itsy outer surface and the inner surface of the hub 8 will be located at an angle with each other. Thisvprovides a thimble practically closed at the bottom and tapered to a smaller diameter toward the top. Lead is then [illedinto the space between the section 3 and the hub 8, as shown at 13. in the drawings. It will be seen that when the joint is finished` thethimble has been tightly secured in place and Vforms practically an extensible integral part of the section 3. The tapered space between the thimble and hub 8 affords means for causing the thimble to tightly grasp the section 3, and a firm and secure joint is thus obtained, practically as firm and strong as are the joints between the other sections of the line.

In Fig. 5 of the drawings the tapered surface by means of which the spigot-section of the fitting is grasped is formed between the thimble and the section 3, the thimble 14 in this form of device having a beveled surface 15, between which and the outer surface of the section 3 the oakum is tightly packed. As the oakum is forced downward into the narrow space the spigot-section 3 is tightly grasped,as before,and a secure joint thus obtained, the thimble being forced into tight contact with the inner wall of the hub 8.

In the form of device shown in Figs. 7, 8, and 9 of the drawings the hub-section 16 is provided with a coarse thread 17, tapering from the mouth of the elongated hub inward toward the bottom. A ring 18, preferably formed in sections and having an outer thread fitting the thread in the hub, is placed about the lower end of the spigot-section 19, and then, as by means of a Spanner-wrench inserted in the holes 20, the ring is screwed tightly to place, the tapered threaded surface on the hub enabling it to tightly grasp the outer surface of the section 19 and hold it in place. Oakum and lead are then packed into the space between the hub 16 and the spigot section of the fitting in the usual manner.
