IMPROVEMENT IN GAS PIPES AND FIXTURES.
Specification formingpart of Letters Patent No. 140,165, dated June 24, 1873; application filed November 16, 1872.
To all whom ti may concern:
Be it known that we JOHN RICHARDSON and THOMAS D. RICHARDSON, of New York, in the county of New York and State of New York, have invented certain Improvements in Gas Pipes and Fixtures, of which the followin g is a specification.
Our invention relates to gas pipes and fixtures for oxy-hydrogen and similar lights, which require two gases to be conducted separately to the burner, and the invention consists in mounting the pipe which conveys one of the gases concentrically within the pipe which conveys the other gas, and in constructing the elbows, swivels, and couplings, in a manner to correspond, so that the fixtures present the same appearance as those of the ordinary construction which convey but one gas.
Figure 1 is a vertical central section through a chandelier constructed on our plan. Fig. 2 is a horizontal section of the same on the line as m. Fig. 3 is a vertical section through a swivel-bracket constructed on our plan. Figs. 4, 5, and 6 are elbows and joints to be used with our pipe. Fig. 7 is a vertical central section through a drop or extension joint made on our plan. Fig. 8 is a crosssection of our pipe; and Fig. 9 is a view of one of the washers or spiders which hold the inner pipe fast within the other. I
In constructing our pipe we provide a pipe, A, of suflicient size to convey one of the gases, and insert it within a second pipe, B, which should be of such size that the annular space between it and the inner pipe will allow the proper flow of the other gas. The inner pipe we fasten concentrically in the other by means of washers or spiders G, which have a central hole, a, to admit the inner pipe and arms or points I) to bear against the inner sgurface of the outer pipe 13, as shown in Fig. These washers or spiders may be inserted loosely, or fastened in any suitable manner. It is preferred, however, to secure them on the small tube before it is inserted within the other, so that it will carry them in to their proper positions and hold them there. It is, of course, immaterial in what form the spiders are made, provided they hold the central pipe in position, and do not materially obstruct the flow of the gas through the annular space between the pipes.
It will be seen that our double or compound pipe presents the same external appearance as anordinary single pipe, but that it is at the same time capable of conveying two different gases without allowing them to come in contact with each other.
In using our pipe we employ in connection therewith couplings, elbows, and joints of like construction--that is to say, composed of two concentric tubesso that they will convey the gases from one section of pipe to another without allowing them to come in contact.
Fig. 6 represents a simple elbow, and Fig. 5 a T-piece, of our construction. Fig. 4 represents a joint for making a connection between two ordinary pipes carrying the separate gases, and our improved pipe for carrying both. This is of course intended for use only where all the pipes are stationary.
Where a swinging arm or bracket on our plan is to .be connected with two stationary supply-pipes, we connect it therewith by means of a swivel-joint, as shown in Fig. 3. This joint is the same as those of the ordinary c011- struction, except that instead of having one passage it has two, one communicating with the central and the other with the outer tube of the arm or bracket.
When chandeliers are made on our plan the main pipe or pendant and the arms are all made of the two concentric tubes, and the central tube of the arms connected with the central tube of the pendant, as shown'in Figs. 1 and 2. By this arrangement the two gases are conveyed separately through the arms to the burners.
Extension or drop lights may also be constructed of our pipe, as shown in Fig. 7, by arranging one section of pipe to slide teles copically within another, in the same manner as is done with the ordinary single pipe.
By means of suitable joints and connections our pipe may, it will be seen from the above, be employed for all purposes and in the same manner as the ordinary single pipe in common use. The different sections and fixtures may be screwed together or connected in any suit able manner.
Any suitable cock may, of course, be employed for controlling the flow of the gases, but it is considered preferable to use the one for which we have this day made an application, as it serves to control both gases at the same time.
The pipe and fixtures constructed according to our invention enable us to provide brackets, chandeliers, and other burners and apparatus, which present the same appearance as those of the ordinary construction, and at the same time convey the two gases separately.
In order to accomplish the same end with pipe of the ordinary form it becomes necessary to use two parallel pieces, which render the burners very clumsy and objectionable in appearance, but by means of our improvements this objection is entirely avoided. Our pipe may also beset in place with far less trouble than two separate pipes, and may be arranged in many places where it would not be convenient or possible to arrange two separate ones.
While it is considered preferable to have the two tubes arranged concentrically it is not necessary, as the inner tube may be placed eccentrically, provided its ends are concentric with the other, in order to allow the other sections or couplings to be screwed thereto.
Having thus described our invention, what we claim is 1. The herein-described pipe for conducting two gases separately between distant points, consisting of two pipes secured one within the other, substantially as herein described, with their ends arranged concentrically, as set forth, so that different lengths or sections of the compound pipe may be screwed together and used in the same manner as ordinary single pipe. r
2. The combination of the pipes A and B with the spiders C or their equivalents, as and for the purpose described.
3. In combination with the compound pipe A B, the swivel D provided with the two passages or openings, substantially as described.
