EXPANSION JOINT.
No. 388,915 Patented Sept. 4, 1888.

EXPANSION-JONT.
SPECIFICATION forming part of Letters Patent No. 388,915, dated September 4, 1888.
Application filed June 22, 1887. Serial No. 242,133. (No model.)
To aZZ whom it may concern:
Be it known that we, RoNELLo F. PRATT, a citizen ofthe United States, residing at Revere, in the county of Snolk and State of Massachusetts, and CHARLES D. WAINWEIGHT, a citizen of the United States, residing at Med` ford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Expansion-Joints,ofwhich the following is a specification. Y
Our invention relates to the construction of expansionjoints used in steam or hot-water pipes or any purpose requiring an expansionjoint; and the invention consists in constructing the joint of spiraliy-corrugated seamless drawn tubing, the ends o f which are secured in a casting provided with a flange for attach ment to the line of pipes, a straight tube passing through the corrugated tube and provided at each end wit-h a ring or stop 'that works freelyin the casting secured to the corrugated tubing, snlicient room being allowed for the expansion and contraction ot' the said corrugated tubing, as more fully hereinafter dc scribed.
Referring to the accompanying drawings, Figure 1 represents a side elevation of an expansion-joint embodying our invention. Fig'. 2 is an end view of the same.' Fig. 3 is a cross-section taken on line xxof Fig. 1. Fig. 4 is a longitudinal section through the expansionjoint. n
'A represents a piece of spirally-corrngated seamless drawn tubing, theouterends of which are inserted in a iianged ring, B, and are securely held therein by means of a ring, C, driven inside the tube A, so as to expand it and compress it between thc said ring C and the Banged ring B, this being one of a. number of known ways for joining a flange and tube.
W'e prefer to turn the ends of the tube A over at about right angles, as shown at a a, so as to insure the tube being held tight, and thereby preventing any chanceof the tube working out from between the said rings.
D is a slip-tube passing through the corrugated tube and rings C C, and is provided at each end with a coilar, E E, as shown, or with stops. The ring C being recessed out, as shown, so as to allow of a space for the rings E E or stops to work in, a ring, F, is screwed into the ring G and held firmly therein by means of screws f f. (See Figs. 2 and 4.) The ring F forms a stop in one direction and a shoulder, c, forms a stop in the other direction, so that there is a clear space at each end to allow the ring C to work on the slip-tnbe,
or the slip-tube to work in the ring C, according to the expansion or contraction of the 6o pipes. By this arrangement ot stops for the slip tube E each expansionjoint will do its proportionate part of the work--that is to say,
if, for example, an expansionjoint is placed. in every fifty/feet in the line of pipes, then each joint will take up its proportionate part of the expansion and contraction in the entire length of pipe, thereby equalizing the amount of work done by each expansion-joint.
Each of the rings B B is provided with a 7o ange, b,and projections or bosses bb', through which bolt-holes are formed for securing the expansionjoint in the line ot pipes; or the joint may be connected bymeans of a screw-I joint, in which case the ring F is screwy threaded on its inner side to receive the end of the pipe and the projections or bosses b', and the bolt-holes can be dispensed with.
As steam is passed into the pipes by periodical injection, it causes the pipes to be alter- 8o nately heated and cooled, causing a series of expansions and contractions t0 be constantly taking place in the pipes, which expansion and contraction is taken up by the spirally-corrugated tube A, thereby preserving the joints andrpreventing leakage.
What we claim as our invention isf- In an expansionjoint, a spirally-corrugated tube, A,connected at each end, in substa-itiall y the manner described, with a flange, B, anda 9o slip-tube, D, provided at each end with a ring, E, in combination with the stop c upon said flange, and the stop-ringF, whereby the motion of the sliptube is limited and the passage through the side in a straight line is uninterrupted, all as set forth. In testimony whereof we have signed on names to this specification in the presence of two subscribing witnesses.
