Application February 21, 1939, Serial No. 257,025 l 3 Claims.
This invention relates to improvements in sound insulating fluid conductors.
In many private dwellings, hotels and public buildings objectionable noises emanate from the plumbing fixtures when the latter are operated,
and these noises are often transmitted for a considerable distance along the pipes leading to or from the fixtures and are audible in rooms other than those in which the fixtures are located to the great annoyance of the occupants of these rooms.
The object of this invention is to provide an effective sound insulating fluid conductor for plumbing and like installations, said conductor forming a part of the fluid supply pipe leading to the various plumbing xtures and being interposed in the system at strategic locations therein, preferably adjacent to said fixtures, said conductor having a plurality of sleeves of novel construction embodied therein which contact with the conductor wall in a manner to effectively reduce the vibratory quality of the metallic conductor and to absorb the sound waves passing along the `conductor wall, thereby preventing the vibrations or waves from continuing along the conductor to points in the plumbing system where they may cause annoyance.
The invention consists of a sound insulating fluid conductor as set forth in the following specification and particularly as pointed out in the claims.
Referring to the drawing:
Fig. 1 represents a perspective view of a typical plumbing installation, including sound insulating fluid conductors embodying my invention interposed in the plumbing system adjacent to hot and cold water faucets.
Fig. 2 is a longitudinal sectional elevation illustratlng a portion of a sound insulating fluid conductor and disclosing several sound absorbing sleeves mounted within a fluid conducting pipe in circumferential contact therewith.
Fig. 3 ls a detail transverse section through the sound insulating fluid conductor as taken on the line 3-3 of F18. 2.
Figs. 4, 5 and 6 are sectional views similar to Fig. 3, but illustrating modified embodiments of the invention.
Fig. 7 is a longitudinal sectional elevation illustrating another modified embodiment of my invention in which the sound absorbing sleeves arey mounted upon the exterior of a fluid conducting pipe in circumferential contact therewith.
Fig. 8 is a detail transverse section taken on 56 the line l-O of Fig. 7.
Figs. 9 and 10 are sectional views similar to Fig. 8 illustrating other modified embodiments of the invention.
Like numerals refer to like parts throughout the several views of the drawing. s
In the drawing, referring particularly to Figs. 1, 2 and 3, A represents a plumbing fixture which, in this instance, is a wash bowl. although the fixture may be a bathtub, flush tank, reducing valve, water meter, pump, or any other appa- 1o ratus from which water is discharged or through which water or any other fluids pass, and in which various forms of noises develop as a result of the discharge or flow of said fluids. The wash bowl A is provided with hot and cold water 1| faucets l2 and il respectively, both of which have a sound insulating fluid conductor Il constructed in accordance with the teachings of this invention communicating therewith and constitutuing a portion of the water supply pipe for 20 each faucet. In the plumbing installation illustrated in Fig. 1 the fluid conductor is attached direcly to the faucets and extends therefrom for a suitable distance determined by the type and character of the fixtures. A length of the con- 2l ductor may, however, be interposed at strategic locations in the plumbing system in a manner to absorb noises emanating from a group of fixtures.
The construction of the sound insulating fluid conductor il is as follows: Inserted in a length of metallic fluid conducting pipe or tubing l5 of any well known type, in co-axial relation therewith, are a plurality of relatively'short sleeves I6, preferably formed of metal and having an easy $5 slide or close running fit within said pipe as defined in Machinerys Handbook for machine shop and drafting room, 10th edition, 1939, Eric Oberg and F. D. Jones, editors, page 1132, together with tables for clearances for particular diameters as 40 disclosed on page 1129. The sleeves I6 are rounded or bevelled at their ends as illustrated in Fig. 2, and said sleeves may or may not abut together end to/end, but preferably they abut as illustrated in Fig. 2. The sleeves I6 are pro- 45 vided with walls of uneven area and thickness in cross-sectional contour, thereby providing an uneven weight distribution throughout the length of the sleeves. In Fig. 3, five intersecting walls il of unequal area and thickness are illus- 5o trated, but it will be clearly understood that the actual number of these walls is immaterial as long as an uneven distribution of weight is obtained. Furthermore, an important consideration ln this invention is that the combined u weight per foot of the sleeves exceeds the Weight per foot of the fluid conducting pipe carrying said sleeves.
The action of the sleeves il in easy sliding circumferential contact with the interior wall of the pipe i5 is to reduce the vibratory quality of the metallic pipe, and to absorb the sound waves passing along said pipe within themselves. thus preventing said waves from continuing along the pipe wall to points in the Iiuid conducting system where they may cause annoyance. Although the sleeves i6 abut one with another within the pipe I5, said sleeves do not necessarily align one with another, and preferably they are not positioned in alignment.
In Figs. 4, 5 and 6 other embodiments of my invention are illustrated wherein sound absorbing sleeves formed in accordance with the teachings of this invention, but which may vary somewhat in effectiveness, are mounted within iluid conducting pipes I5 to have an easy slide or close running tit therein.
In Fig. 4 a sleeve il is provided with an odd number of intersecting walls of equal area and uneven thickness in cross-sectional contour, thereby providing an uneven weight distribution throughout the sleeve.
In Fig. 5 a sleeve 2l having an easy slide or close running t within a pipe il is provided with an even number of intersecting walls of equal area and uneven thickness in cross-sectional contour, thereby providing an uneven weight distribution throughout the sleeve.
In Fig. 6 a cylindrical sleeve 22 is mounted within the interior of a pipe l5 to have an easy slide or close running nt therein. In this embodiment vof the invention the weight distribution is even, but the sleeves have the ability of absorbing the sound vibrations to a certain degree because of their easy slide lit within the pipe i5, and because of their superiority of weight.
In Figs. 7 and 8 another embodiment of my invention is illustrated wherein a plurality of relatively short metallic sleeves 2| are mounted end to end upon the periphery of a pipe or tube i5 in co-axial relation therewith and to have an easy slide or close running fit therewith. The sleeves 2| are provided with an irregular exterior surface preferably consisting of a plurality of intersecting longitudinally extending walls 25 of uneven area and thickness, thereby creating an uneven weight distribution throughout the sleeve.
In Fig. 8, iive intersecting walls 2i ci unequal width are illustrated, but it will be understood that the number of said walls may vary if desired. The important consideration is the easy slide or close running fit of the sleeves 2l upon the pipe I5, the uneven weight distribution of the sleevesl and the superiority oi' weight per foot of the sleeves over the weight per foot of the pipe.
In Fig. 9 a sleeve 26 has an easy slide or close running t upon a an odd number of intersecting walls 21 of equal area but uneven thickness, thereby providing an uneven weight distribution throughout the sleeve.
Fig. 10 illustrates a cylindrical sleeve 2l mounted to have an easy slide or close running fit within the exterior of a pipe I5.
The action of the various embodiments of the invention' illustrated in Figs. 7, 8, 9 and 10 is substantially the same as that of the corresponding structures illustrated in Figs. 2, 3, 4 and 6 respectively.
In all of the embodiments of the invention the weight per foot of the sleeves exceeds the weight per foot of the iiuid conducting pipe carrying said sleeves, and in each instance the sleeves have an easy slide or close running nt within the pipe carrying said sleeves as defined in the authority quoted.
I claim:
1. A sound insulating iiuid conductor of the character described comprising, in combination, a metallic uid conducting pipe, and a sleeve in co-axial relation therecomprising, in combination, a metallic fluid conducting pipe, and a sleeve of unsymmetrical cross-sectional area carried by said pipe in co-axial relation therewith and having a full circumferential contact and easy slide tit therewith, the weight per foot of said sleeve exceeding the weight per foot of the pipe carrying said sleeve.
3. A sound insulating uid conductor of the character described comprising, in combination. a metallic fluid conducting pipe, mounted lengthwise within said pipe and having an easy slide fit therein, the weight per foot of said sleeve exceeding the weight per foot of the pipe carrying said sleeve. l
