EXPANSION-JOINT.
Speoication of Letters Patent.
Patented Oct. 21, 1919.
To all whom t may concern.'
Be it known that I, JOHN Amnnr BpGAnT, a citizen of the United States, residing at Buifalo, in the county of Erie and State of New York, have invented a new and useful Expansion-Joint, of which the following 1s a specification.
My invention relates to expansion joints for piping, such as steam-pipes, water-pipes, and the llke, and is an improvement upon the common slip-joint.
The objectof my invention 1s provlde 'an expansion joint of the s l-ip-jomt type wherein, and among other things, these objects are attained, namely: supportof the joint and the line pi ing; adjustabilltyof packing without any isassemblmg of parts; prevention of pulling apart of the sbp-joint under conditions of extreme pipe contraction or improper assembling or adjustment of parts 1n setting up; the provision of a joint which maybe adjusted readily in assemblmg, readily disassembled, repacked, etc., without any disturbance of the line' pi ing. Other and further objects will be evi ent from the following specification and claims and from the annexed drawings, in which,
Figure 1 is a side elevation of my lnvention 1n assembled position.
Fig. 2 is an axial section of Fig. 1.
Fig. 8 is an elevation showing the parts disassembled for repacking or other purform of Fig. 7. l
half-section detail show- Fig. 9 is another ing another form of stop construction.
It is to be observed here that the stop device is omitted in'Figs. 1, 2 and 8, because,
first, the main, central feature of my invention may be employed without any stop means, and, secon-d, because this form of illustration aifords clearness.
The two adjacent sections of the line piping at the point where axial movement is to be taken care of are shown at 1 and 2, the section 1 being threaded to or otherwise secured to or integral with the flange 4, and the section 2 being provided with an ordinary end-Bange 3. A. shortsection of piping 5,-pre:ferably of noncorrosive metal, such as bronze, has threaded or otherwise secured to it a ange 6, which iange 6 is bolted to the flange 4 to form a fluid-tight joint. The pipe section 5 is machined on its outer surface and Afits slidably within the main body 7 0f the joint. This main body 7 has a ange 8 bolted fluid-tight to the Bange 8, and at its other end is recessed to receive the packing 9 and gland 10.
The parts thus described, while in improved mechanical form. are approximately those of the ordinary slip-joint, and with these elements indicated which I employ in my new combinations, I will now indicate and describe my improvements.
The main body 7 has an extension Hang-e 11. 'To this flange 11 is bolted a guide-sleeve 12, which is machined internally and which extends over and makes a good sliding' joint with the flanges 4 and 6, one or both of which are machined upon their peripheries. This addition and improvement constitutes the iirst and. main feature of my invention; and it will now be seen that this guide-slve 12, rigidly secured, to the main body member 7 and fitting snugly but slidablv over the anges 4 and 6, provides a guide and support which prevents sagging of the pipe line or strain upon or displacement of the packing joint-objectionable conditions which have rendered the ordinary slip-joint undesirable, and the removal of which renders the' slip-joint type of compensation the most ldesirable type. Moreover, by reference to Fig. 8 especially, it will be seen thatmy improvement above described 'not only meets these objections, but affords means of asasA 'ting these oi'sets,'and thus outside the sembling, disassembling and repacking without any disturbance of the pipe line itself.
Coming now to the second main feature of my invention, since the guide-sleeve 12, except for the improvement now stated, would so inclose the gland-bolts that the guide-sleeve would have to be removed to adjustthe gland, and since such removal not only would make the adjustment more laborious but would necessitate such adjustment at the time when the support of the guidesleeve was removed, so that the ad`ustment might occur with the parts out o crfect alinement, I provide the main body with the oi'sets 13, which are bored to receive the gland-bolts 14, which have their nuts abit- 1 esleeve, so that the packingmay be adjusted by the gland at any time without removal of the guide-sleeve and while the parts are held by the ide-sleeve in perfect alin'ementt The t ird main feature of my invention, as above indicated, consists of stop means for preventing pulling apart of the joint under conditions of undue contraction or improper setting-up; for with the ordinary type 'of slip-joint it is not uncommon to have the members pull apart'and cause serious damage. In Figs. 4, 5 and 6 I have shown the preferable form of my improvement. The guide-sleeve 12 is rovided with an outstanding flange 15 or I may use outstanding lugs arranged about the periphery of the guide-sleeve), over which are placed stops 16 secured thereto by bolts and havin their inwardly-extending, or L-shaped, en s cross the path of the sliding joint between the guide-sleeve 12 and the flanges 4 and 6. In Fig. 4 I have shown this feature with the parts in the position when the limit of pipe contraction ermissible at the joint has been reached, and) further movement at this pointprevented by the Stops 16 contacting the ange 4.
In Figs. 7 and 8 I have illustrated equiva lent means for attaining this end which consist in casting the guide-sleeve 12 in wo longitudinal parte, provided at its ee end with an inwardly-projecting liange 17, which crosses the path of the sliding joint between the guide sleeve and the ilanges 4 and 6, in manner similar to the stops 16; and at the other end is provided with a grooved or rabvbeted flange 18 lwhich takes over the liange 11 on the main body 7, and is clamped thereto by means of side-lugs 19 and bolts 20.V
rI his construction attains the same ends as said first-mentioned construction in Figs. 4,
5 and 6, and may be likewise removed without removal of the anges 4 and 6.
Under some conditions-this feature of my `invention may be attained by the simple means' shown in Fig. 9, wherein ordinary .andla set-screws 21 are threaded through the guide-sleeve 12 and extend across the path of the joint between said sleeve and the ian s 4 and 6.
T e fourth main feature of my invention arises from the combination and coperative ation of the improvements above described, whereby assembling, disassembling, repair, or adjustment are eil'ected without any disturbance' of the line piping.
I do not wish to limit myself to the elpeciic constructions shown and described, ut claim 1. In combination with two sections of a pipe line, a'casing attached to the end of one pipe section, a tubular member on the end of'the other pipe section and slidably disposed in said casing, an annular head on said tubular member, and a sleeve secured to said casing and extending over said head to form a. protective chamber in which the sliding surface of said tubular member is disposed.
2. A device of the character described comprising` a casing, a tubular member slidably mounted in said casing, and a sleeve secured to said ca sing and extending over the sliding surface of said tubular member to prevent the accumulation or discharge thereon of foreign material.A
8. A device of the character described comprising a casing, a tubular member slidably` mounted in said casing, an annular headfon said tubular member, a sleeve secured to said casing and extending over such head to form a protective member in which the sliding surface of said tubular member is disposed. and stopping means formed on the free edge of said sleeve over-hanging said head and extending into the path of movement of said head so that the outward movement of said tubular member is limited.
4. In combination with two sections of a pipe line. a casing attached to 'the-end of one pipe section and recessed to receive packing packing` gland and having holes to receive through-bolts for said gland, a tubular member on the -other pipe section and slidably disposed in said casing, an annular head on said tubular member, a sleeve secured to said casing and extending over said head, packing and a packing gland in said casing, and 'gland-bolts engaging said gland and extending through said holes in said casing and adapted to the adjustment of said gland` whereby a closed chamber is formed to protect the joint and whereby said gland may be adjusted without disturbance or disassembling of said otherparts.
5. An expansion joint comprising a v,main bodysecured to one side of the pipe line provided with a recess gland, an extension Bange to attach acylindrical sleeve and oisets bored to receive for packing and Aa iio gland-bolts! ckmg' land-bolts and .Y section to forni a closed chamber and sup-VV gland, a. shda le g other side of sai pipoine-oiztemally ma.- chined and sliding within sam 5` and a cylindrical sleovo rigily o. said main body, iinternally taking over the ange of sction to the port'for the joint `so formal.
