C. W. VALENTINE EXPANSION JOINT Filed May 1927 Patented Feb. 12,1929.
UNITED STATES PATENT OFFICE.
CHARLES W. VALENTINE, OF WATERTOWN, NEW'YORK, ASSIGNOR TO THE BAGLEY -AND SEWALL COMPANY, OF WATEBTOWN, NEW YORK, A CORPORATION OF NEW YOBIIL.
Application filed May 7,
This invention relates to certain improvements in expansion joints for steam pipes and has been designed particularly for use with the drying rolls of a paper making machine, though it is useful in other relations.
It is the especial object of the present invention to produce an expansion joint for steam pipes in which a tight fit is provided,
but which at the same time will have the desired flexibility.without the need of any slip joint through a packing box, the construct on being such as to be simple and, therefore, 1nexpensive to produce and easy to assemble.
With this and other objects not specifically referred to in view, the invention consists in certain novel parts, arrangements and combinations which will be described in connec tion with the accompanying drawings and the novel features pointed out in the claims hereunto annexed.
In these drawings,-
Figure 1 is a topview of a construct on embodying the invention, looking in the direction of arrow 1 of Figure 2;
Figure 2 is a vertical section taken on the line 2--2 of Figure 1, and
Figure 3 is a cross section taken on the line 3-3 of Figure 2.
Referring now to these drawings, which show a preferred embodiment of the invention, there is provided a nipple section 1 threaded as at 2 to receive the end of a steam pipe. Below this nipple section 1 is a sleeve 3, the section 1 being locked to the sleeve 3 by meansof a lock-nut 4, this lock-nut being threaded to the sleeve and having a collar 5 engaging a flange 6 formed on the end of the nipple section 1. Having a tight slidingfit 1n the lower end of the sleeve is a second nipple section 7, the outer end of which is threaded as at 8 to receive a pipe. Within the sleeve 3 is a flexible expansion member, shown in the form of a bellows, made of light metal so that it can expand and contract, this expansion member being marked 9. The member 9 is anchored at one end, by a lock-nut 10. to the threaded depending flange 11 of a flanged member 12 having a peripheral flange 13 which seats on the upper end of the sleeve and is locked in place by the lock-nut 4, before referred to a gasket, as 14, being preferably interposed between the end of the nipple section 1 and the flange 13. The other end of the flexible member '9 is secured to a lock-nut 15 EXPANSION JOINT.
1927. Serial No. 189,515.
having a depending flange 16 by which it 65 may be screwed to the upper end of the nipple sectlon 7 The lock-nut 15 has a peripheral flange 17 which is arranged to engage with a contracted portion 18 in the sleeve, so as to limit the expanding movement of the bellows member 9.
In the best constructions, means are provided for preventing the twisting or turning of the member 9 so as to prevent damage thereto. While these means may be somewhat varied, in the particular construction illustrated this is simply and easily effected by shaping the sleeve 3 so that its interior surface is hexagonal, and correspondingly formmg the outer section of the nipple section 7. With the parts thus shaped the tubing is prevented from turning or twisting while in use.
It will be observed that but one gasket is necessary, and that all the parts are held together b the lock-nut 4 without the necessity of their eing any bolts or screws for effecting the securing of the parts. Thus a very simple structure is provided, and one which is cheap to make, and easy to assemble.
While the invention has been shown in its preferred form, it will be understood that certain changes and variations in the construction and arrangement of the parts may be made without departing from the invention as defined in the appended claims.
What I claim is:
1. In a pipe joint, the combination of a sleeve, a nipple section at one end of the sleeve, a second nipple section having a slidmg fit in the other end of the sleeve, a flexible member in the sleeve between the nipple sections, said member being anchored at one end and secured at its other to the sliding nipple section, means for locking one of the nipple sections and the sleeve to ether, and means for preventing the flexible member from turning.
2. In a pipe'joint, the combination of a sleeve interionly polygonal in shape, a nipple section at one end of the sleeve, 2. second nipple section exteriorly polygonal in shape havmg a sliding fit in the other end of the sleeve, a bellows shaped tube of flexible'r netal in the sleeve between the sections, said tube being anchored at one end and secured at its other to the sliding nipple section, and means for locking one of the nipple sections and the sleeve together.
-choring one end of the flexible member, a
second nipple section having a sliding fit in the opposite end of the sleeve, a lock-nut securing the-other end of the flexible member to the sliding nipple section, and a threaded clamping collar for locking one of the nipple sections, the threaded memberand the sleeve together.
4 In a pipe joint, the combination of a sleeve having a threaded end, a nipple section at one end of the sleeve, a flexible member in the sleeve, a threaded member below the nipple, means for anchoring one end of the flexible member to the threaded member, a second nipple section having a sliding fit in the opposite end of the sleeve, a flanged member locking the other end of the flexible member to the sliding nipple section, a seat in the sleeve engaged by the flanged member for limiting the movement of the flexible member, and means for locking one of the nipple sections, the threaded member and the sleeve together.
5. In a pipe joint, the combination of a sleeve having a threaded end,a nipple section at one end of the sleeve having a flange, a flexible member in the sleeve, a threaded member having a flange seated on the end of the sleeve, means for locking one end of the flexible member to the threaded member, a threaded collar. having aflange and acting to clamp the nipple section, the threaded member and the sleeve together, a second nipple section having a sliding fit in the sleeve, and a lock-nut engaging the sliding nipple section for locking the other end of the flexible member thereto.
In testimony whereof, I have hereunto set my hand.
