wihauaea JOHN O. OAREL, OF DULUTH, MINNESOTA.
PIPE-COUPLING.
Specification of Letters Patent.
Patented Dec. 24, 1907.
Application filed January 31 1907- Serial No. 355,026.
To all whom it may concern:
Be it known that I, JOHN G. OAREL, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented a new and useful Pipe-Coupling; 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 the art to which it appertains to make and use the same.
This invention relates to apipe-coupling, especially designed for use in connection with steam and exhaust pipes of a locomotive; but specifically speaking in connection with the smoke box thereof; it has been discovered by experience, that the leakage from the steam or exhaust pipes destroys a perfect vacuum, by the entrance of steam into the smoke box. This relieves the fire of the draft that it should otherwise have; and the result is a bad steaming engine.
Primarily and essentially, the invention has for its object to provide a device of this nature comprising simple and eflicient parts, Which will effectually overconi e the above set forth disadvantages.
This invention comprises further objects and combinations of elements which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.
To obtain a full and correct understanding of the details of construction, combinations of features, elements and advantages, reference is to be had to the hereinafter set forth description and the accompanying drawings in connection therewith, wherein Figure 1 is a front elevation of a locomotive showing the relative osition of the device in connection with t e steam and exhaust pipes of the smoke box thereof. Fig. 2 is a sectional view of the coupling device showing the relative positions of the diifer-.
ent parts thereof. Fig. 3 is a detail view of one of the parts of the coupling.
Making renewed reference to the accompanying drawings, wherein similar reference characters indicate corresponding parts in the several illustrations, by figures,1 and 2 designate two sections of a pipe, each section thereof being annularly recessed, as at 3, upon the inner circumference thereof; these recessed portions, when the two sections of the pipe are placed together, receive and hold the sleeve 4 which may be'of any suitable metal, preferably brass. This sleeve 4 is provided at each end thereof with annular recesses 5, designed to receive expansion rings 6, the outer faces of which rings, as shown, are not flush with the circumference of the sleeve; this is for the purpose of allowing then to seat themselves, that is the rings, into annular depressions 7 of the two sections of the pipe, as shown clearly in Fig. 2 of the accompanying drawings; this construction forms a very tight and compact coupling, as will be evident, and which will prevent leakage, as has been practically de:nonstrated.
The two sections of the pipe are provided with flanges 8, one flange being provided with an. annular convex portion 9, while the other flange is provided with an annular concave depression 10, designed to receive the portion 9, when the two flanges are placed and fixed together, by means of a nut and bolt 11, as clearly shown in Fig. 2.
The sections of the device are provided with annular recesses 9 and 10, which are adjacent the annular convex and concave portions of the sections; these recesses are designed as shownto receive a packing ring 10 so as to render to the fullest extent, an absolute steam and water tight pipe-j oint, as will be readily understood.
The sleeve is provided upon its inner circumference, and at each end thereof, with a plurality of threads '12, to facilitate the insertion of a plug for the removal of the sleeve, when it is desired to repair the device, as will be clearly evident.
The depressions of the pipe sections are designed to be very slight, in practice, and the corners of the said depressions are designed to be slightly rounded so as to allow the rings, which in practice, are expansion rings capable of contraction so as to allow for their insertion into said depression, to be withdrawn from the said depressions, that is, when the proper pulling force is exerted upon the wrench, used for removing the sleeve; there will be also, a slight space, left between the inner circumference of the rings and the bottoms of the annular recesses 5 of the said sleeve; this space, in practice, is so slight that it is hardly distinguishable as will be clearly manifest. The insertion and the removal of the sleeve is accomplished by considerable force. This particular construction of joints provides a very desirable water and steam tight connection.
It is to be understood that various changes and modifications may be employed in the construction and embodiment thereof, combinations of features, and elements, Without in any way departing from the spirit and scope of the invention covered by the claims thereof; it being understood that whatever variations or modifications are employed must fall Within the scope of the appended claims.
From the foregoing, the essential features, elements and the operation of the device, together with. the simplicity thereof, will be clearly apparent, and, when manufactured in accordance with the invention, an inexpensive market will be easily obtained. there- Having thus fully described the invention, what is claimed as new and useful by the protection of Letters Patent, is
1. A pipe-coupling comprising two flanged sections of a pipe, the flange of one of said sections having an annular convex portion, the flange of the other section having an annular concave portion to receive said annular convex portion each section being recessed, a sleeve to be received by said recesses when the sections are fixed together, said sleeve having annular recesses at each end. thereof, expansible rings carried by said annular recesses, said recesses of the sections having annular depressions to partially receive said expansible rings, said sleeve having a plurality of threads upon its inner circumference at each end thereof to facilitate the insertion of a plug for the removal of the sleeve, the said sections having-annular recesses adjacent the concave and convex portions of the said sections, a suitable packing fixed therein, and nuts and bolts securing said flanges together. i
2. A pipe-coupling comprising two flanged sections of apipe, each section being recessed, a sleeve to be received by said recesses when the sections are flxed together, said sleeve having annular recesses at each end thereof, expansible rings carried by said annular recesses, said recesses of the sections having annular depression to partially receive said expansible rings, said sleeve having a plurality of threads upon its inner circumference at each end thereof, to facilitate the in sertion of a plug for the removal of the sleeve.
3. A pipe-coupling comprising two flanged sections of a pipe, the flange of one of said sections having an annular convex portion, the flange of the other section having an annular concave portion to receive said annular convex portion, each section being recessed, a sleeve to be received by said recesses when the sections are fixed together, said sleeve having annular recesses at each end thereof, expansible rings carried by said annular recesses, said recesses of the sections having annular depression to partially receive said expansible rings, said sleeve having a plurality of threads upon its inner circumference at each end thereof, to facilitate the insertion of a plug for the removal of the sleeve, and nuts and bolts to fasten the flanges of the sections.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
