EXPANSION-JOINT.
Spepification of Letters Patent.
Patented Feb. 22, 1910.
Application filed February 16, 1969. Serial No. 178.175.
of Xew York, have invented certain new and useful Improvements in Expansion- Joints: and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in [in art to which it appertains to make and use the same.
The present invention relates to improvements in expansion-joints, that is to say,
joints adapted to permit the expansion oi'i pipes in steam pipe lines, Where variations in temperaturqboth internally and externally, have a peculiar expanding and controt-ting eli'cct upon the pipe sections.
All of the expansion-joints now in use, are difiicult to keep in working order, and entail considerable time and expense to keep them tight at all times, and it is my present object to present a joint, in which there is little lihelihod of its getting out of order, or becoming leaky.
When a great number of expansion-joints employed in a steam-heating system, is taken into consideration, and it is appreciated that each one of these require constant repair and attention'with the structures now in use, the large amount of trouble and expense saved by this invention is readily seen, inasmuch as the joints which I employ require very little and practically no care, after once. being installed.
With these set-oral objects and advantages in view, my invention in its preferred embodiment. includes the form of construe:
tion hereinafter specifically describeiwmd pointed out in the. appended claim.
In the accompanying drawings, forming a part of this specification, and wherein like reference characters refer to corresponding parts in the several views, Figure I is :1 iongitudinal sectional view of a double expansion-joint embody'ng my invention; Fig. 11 is a similar view of a double expansion-joint, employed in a steam supply system, and including a service opening for tapping the main; Fig. 5H is a longitudinal sectional view of a single expansioc-ioint :nbodyiug my present improvements; F lg. 1 -3 a de tail view showing in partial elevation. the
gland which I use; Fig. V is a longitudinal sectional View of a single expansion-joint, constructed according to my resent invention. and provided with a service pipe for tapping the main; and Fig. VI is an end elevation of the form disclosed in Fig. V.
Referring more particularly to the drawi, ing, and to Fig. I, A designates the body l l I w 1 portion of the joint, the same having 2. central depending part B, which is screwthreaded at either side, for a purpose presenzly to be made clear.
a are intcrnally-projecting rings formed termediate the central portion B and the 3 ends of the body portion.
, U are brass tubular slips, screw-threaded lat their ends, and adapted to engage the Zscrew-threaded portions of the progecting part. B of the body portion, and to lie flush with the innermost surface of said projecting part. The slips C are provided upon their exterior surface with circumferentially-arrangcd grooves 0.
D aie tubular slips of iron, which fit in and form a piston between the brass slips C- and the internal rings a upon the body portion A. Interiorly of the slips D are; the grooves (Z, which coiiperate with the before mentioned grooves 0 to form 9. waterpacking, similar to that employed in connection with pump pistons. The slips D are provided with flanges-E, to which the pipe sections are bolted.
F designates the 'land, which is provided with a brass lining 1'. The space H between the body portion A and the slip D, is filled farred. This pac ring is employed simply i as a precaution, and is not necessarily essential to the effective operation of the device. The space G, between the body portion A and tie internal slip C, is intended to be i filled with a liquid-seal of oil, water, or other suitable liquid, which is introduced through the opening e. I indicates lugs formed upon the body portion A, by which the expansionable foundation of cement, masonry, or other material.
In Fig. II, the construction is substantially similar to that of Fig. I, with the exception that the body portion is provided with a no A leading therefrom, in order :tii'ort. 1 means for tapping the main, for 3 obtaining service at the expansion-joint.
* In Fig. III 1 ha e shown the construction 2 embodied in a single expansion-joint, the ar- 1 rangement being the sumo as with the double ateaeh end of the body portion A, and iu-' joint may be secured or anchored to a suit-' with any suitable packing, metal being prewhich the steam can lind an exit is by pass- I and I do not desire to be limited to the preexpansion-joint structure.

provement, but with a service pipe leading from the body portion. as in Fig. II. and claim is:
Instead of constructing the device as 1 An expansion joint of the character deahove described, 1 may form the inner scrihed, including a body portion having tubular slips C of iron. making the outer {an inwardly prO ecting flange, said flange slips 1) of brass, in which case, the bra" lining f upon the gland F may be dispensed threaded slip in engagement with said with. The principal purpose of making this houlder and having its inner surface flush gland with a brass lining is to carry out the i with the innermost partof the flange to generally desirable principle in steam joint form a continuous passage, 9. second cylin construction, of having dissimilar metal contact with one another in order to avoid rust in and quick destruction.
the possibility of leakage with this form of jointis practically nil. The only way in slip and spaced from the outer wall of the body portion, the said two slips being provided with cooperating circumferential groove on their contacting surfaces a ring ing down between theinncrslip C and outer abutting the ltlSl-lIlGllllUilBtl slip, means for slip I), thence through the liquid seal in allot-ding a liquid seal between said ring ace G, and lastly through the packing box and the heiorenientioned inwardly project- Obviously, this is practically impossible, ing flange, and a gland secured to the outer and the advantage of the improvement lit-s end of the body portion and surrounding in obtaining this result through such a simthe last-mentioned slip. ple arrangement of comparatively few parts. in testimony whereof, I afiix my signa- Of course, various other modifications and I ture, in the presence of two subscribing Witarrangenients may he had, aside from the nesses.
