HENRY O. KELSEY, OF SALAMANCA, NEV YORK, ASSIGNOR OF T'WOz THIRDS TO WASHINGTON S. HATCH AND LA MOTTE HARRINGTON,
OF SAME PLAGE.
Pipsoo UPLlNeQ SPECIFICATION forming part of Letters Patent No. 634,08*?dated October 8, 189,55).
- manca, inthe county of Cattaraugus and State of NewYork, have invented certain new and useful Improvements in Pipe-Couplin gs and I d o hereby declare the following to be a full, clear, and exact description of theinvention,
such as will' enable others skilled in the art to which it appertains to makeand use the same.
This invention has relation to improvements in pipe-couplings of that style or kind adapted for uniting the abutting ends of pipesections, and is particularlydesigned for expeditiously, conveniently, and effectually sealing the joints of pipes against leakage, and therefore the inventionis adapted for the purpose to all kinds of pipe-joints or leaks in pipes. l
The invention consists in the novel construction of parts and their combination, as will be hereinafter more fully described and then particularly pointed out in the claims.
The invention is fully and clearly illustrated in the accompanying drawings, where- Figure l is an end view of the complete device as applied to pipe-sections. Fig. 2 is a vertical longitudinal sectional view through the assembled parts. Figs. 3 and 4- are detail views of the segmental strips or blocks.
It will be premised that it is one of the objects of the invention to provide a means for insuring against leakage at the joints of large conduit pipes, wherein great or excessive pressure is present and usual-such as oilconduit pipes, steam-pipes, water-pipes, andl gas-pipes, wherein at the joints under present and usual pressure the contents of the pipes are forced through the joints and de-y stroy their efficiency and security, and these.
objections and ldefects are overcome or reduced to a minimum by the application of these improvements;
Referring tothe drawings, A A designate two pipe-sections arranged with their ends abutting andprovided with external screwthreads, as usual. B designates the couplingsleeve, of such length as may be desired or required and provided with internal screwthreads to engage with the threads on the V Application tiled July 19, 1899. Serial No. 724,353. (No model.)
pipe ends and couple the same in the usual manner. Thel ends of the coupling-sleeve are preferably rounded or inclined, at as l, to set 'within the recesses or seats formed in the under faces 'of the segmental clamping strips, bars, or blocks.
About the clam ping-sleeve B are seated and disposed a plurality oi' segmental clamping stri ps, bars, or blocks C, arranged side by side and completely surrounding the couplingsleeve, substantially as shownY in the drawings; The vertical sides of these segmental clamping-strips lare formed with elongated recesses or seats 2, those in contiguous segments being coincident, as indicated, and in the space thus formed between the walls of the segments'are placed plates 3, oi' wood orr soft metal, somewhat'thicker than the space in which they set in order that the segments will be slightly separated `and normally be raised from the coupling-sleeve, so that when the segments are forced into clamping position the interposed plates will be pressed tight into position. The segments C are formed with do wnward-extending interior end dan ges 4, which set, down tight over the ends of the coupling-sleeve and compress and tightly seal the sleeve and joint. In the upper surface of each clamping-segment is formed a keygroove 5, in which are placed clamping-keys 6 6, which take under the exterior sleeve and force thesegments down into clamping position, as indicated in Fig. 2 of the drawings.
D designatesan outer sleeve or shell arranged on the segmental strips and`held into position by the force of the keys. I l It will now be perceived that a very strong and durable jointure or coupling has been 'provided which is readily and speedily applied.
In the instance involving the construction and arrangement of parts hereinbefore denew Work and are assembled by iirstscrewing the coupling-sleeve in position on one of the pipel ends, then arranging the' outer shell thereon, then placing the segmental strips and scribed they are adapted for connection with I IOO dcvice to old cond uit-pipes without removing the pipes to be coupled or to a coupling or joint which leaks, the outer ring is made in halves and formed with strong lugs a a', in which are formed alining bolt-holes b b', in which are iitted strong clamping-bolts c c, whereby the sections of the outer ring are drawn tight and firm on the segments and the joint made iirm, tight, and secure.
Instead of the keys set-screws d may be substituted, as indicated in the drawings. It will be perceived that in instances where great strength is not required the segmental strips may be dispensed with and the outer ring set about and over the coupling-sleeve and the keys driven between the couplingsleeve and the outer ring.
It will be perceived that the invention is equally applicable for sealing and closing crevices or cracks in pipes, and in these instances is applied just as when used for a coupling.
Having thus described the invention, what is claimed isp l. The device herein described for sealing crevices in, or in the couplings of pipes, comprising a band orsleeve fitted on the pipe, segmental clamping-strips arranged around the said sleeve,an outer sleeye loosely arranged on the segmental strips, and means for clamping the segmental strips down on the inner sleeve, substantially as described.
2. In a device for closinglea-ks in, or in the couplings of pipes, the combination with the sleeve surroundin g said pipe, of an enveloping casting of larger. diameter than the pipe and segmental clamping strips interposed between the sleeve and casting, having longitudinal channels, and wedges, adapted to be driven in said channels, between the interior of the castingA and said strips, whereby pressure is given the sleeve and forcing it upon the pipe, substantially as described.
3. In a device for closing crevices in, orin the couplings of pipes the combination with the pipe and band, or coupling-sleeve adapted to surround said pipe, and a sectional casting having its interior opening larger than the diameter ofthe pipe and provided with channeled removable blocks, and wedges interes4,o87
posed between thcinterior of the casting and blocks and engaging said channel, whereby when the wedges are driven therein, the blocks force the sleeve tight upon the pipe, substantially as described.
4. A portable closing device for closing crevices in, or in the couplings of pipes, to prevent leakage comprising a sectional casting bolted together having an interior space for surrounding the pipe and of larger diameter than the latter, the band or sleeve and a series of clamping strips or blocks having longitudinal channels adapted to receive wedges,said strips being interposed between the pipe-band and the interior surface of the casting, whereby when the wedges are driven into the channels the blocks or strips forcethe band against the pipe, substantially as described.
5. The within-described device for closing crevices in pipes, consisting of a sectional casting adapted to surround said pipe and hold it together, a band or sleeve and strips interposed between said casting and band on the pipe and having longitudinal channels, and Wedges adapted to be driven in -said channels,whereby the band is forced upon the said pipe, substantially as described.
G. In a device of the character described the combination with a pipe, of a sleeve iitted thereto, a plurality of segmental clampingstrips surrounding thesleeve, plates ot compressible material between the said strips, and an outer sleeveloosely arranged on the said strips, and means to clamp the strips down on theinnersleeve, substantially as set forth.
7. In a device of the character described, the combination with a pipe, of a sleeve fitted thereto, segmental clamping-strips around the sleeve, plates of compressible material between the strips, clamping-sections over the strips, and clamping-bolts to clamp the sections together, substantially as described. In testimony whereof I aflix my signature in presence of two witnesses.
