Abstract
"CLAMP ASSEMBLY"
ABSTRACT OF THE DISCLOSURE
A clamp assembly for attaching a pipe length to a surface comprises two symmetrical halves each formed from mild steel sheet and comprising a jaw portion, a con-necting portion extending at right angles from the surface and a flange portion for connection to the surface. One of the flange portions has elongated slots so that it can slide relative to screws attaching it to the surface to clamp the pipe in the cooperating jaws. The edges of the jaws are spaced by a greater distance than the distance between the coupling portions so that the coupling port-ions can be clamped together to hold the pipe tightly in the jaws.

"CLAMP ASSEMBLY"
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in clamping assemblies for pipes or conduits and de-vices supported thereby. Although it is designed speci-fically for use in supporting gas meters and/or pressure reduction valves 9 nevertheless it will be appreciated that it can be used to clamp any pipe length or conduits whether or not it supports other devices.
It is conventional to provide gas service to re- r sidences via conduits which lead to a pressure reduction or control valve and from there to a gas meter. It is also conventional to mount these components exteriorly of the residence so that the gas meter can be read by a meter reader without entering the residence or business. It will be appreciated that a further conduit then extends from the gas meter, through the wall or supporting surface and into the business or residence whereupon it may be connect-ed to the various appliances utilizing the gas service.
The pipe or conduit assembly carrying the valve and the meter are usually clamped to a substantially ver-tical supporting surface by means of fixed clamps which are engaged around one of the conduits or pipes and secured to the vertical surface. This is inconvenient~ not only in installation due to complete lack of flexibility, but also when it is desired to replace either the meter or the - ~.
~2--valve assembly due to malfunction or the like. Further-more, conventional clamp assemblies must be designed to fit precisely, the conduit or pipe supported thereby which means that a variety of clamps must be available as con-duits do vary, depending upon the gas service installation.
An example of conventional supporting assem-blies is shown ln Canadian patent 991,441 in which the conduit is formed in a U configuration and has brackets welded thereto through which bolts secure same to the sup-porting surface. This arrangment is unsatisfactory in that it is undesirable to weld flanges onto the conduit and also it is very inflexible in use in that the special con-duit so formed does not always fit the situation in rela-tion to the meter and other parts.
A further example is shown in Canadian patent 796,]76 which provides a one piece clamp for mounting on a special support bracket. This is unsatisfactory be-cause it has difficulty accommodating different sizes of pipe and it is expensive and complex to manufacture.

SUMMA~Y OF THE INVENTION
It is one object of the present invention to provide a clamp assembly for clamping a pipe length to a surface which overcomes the above disadvantages.
Accordingly the invention provides a clamp as-sembly comprising two separate cooperating substantially symmetrical clamp members each having a first flat flange portiona means defining at least one opening therein, a second flat flange portion contiguous with the first por-tion and lying in a plane substantially at right angles to the first, means defining an opening in the second por-tion, and a jaw portion contiguous with the second portion and presenting a surface curved about an axis parallel to the plane of the second portion, said at least one open-ing in the first portion of one of the members being elongate in a direction at right angles to the second portion.
It is one advantage of the above invention that the two separate clamp members can be attached to the sur-face roughly adjacent the pipe length by screws or bolts passing through the openings in the first flat portions and with the jaw portions wrapped around or adjacent the pipe length. Subsequently one of the members can be slid toward the other and toward the pipe by virture of the elongate opening or slot in the first portion. Further, a nut and bolt can be passed through the opening in the second portion so as to draw the second portions together and clamp the jaw portions around the pipe length. This movement finally locates the slidable first portion on the surface following which it can be clamped into place by tightening of the screws or bolts.
This makes for ease of installation and ease of removal of ~he pipe or conduit and associated equipment connec~ed or supported thereby~
It also permits one clamp or supporting assembly to be used for a variety of sizes of pipes or conduits, within limits.
Another advantage of the invention is to provide a deviceof the character herewithin described which is simple in construction, economical in manufacture and other-wise well suited to ~he purpose for which it is designed.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the ac-companying drawings forming a part hereof, which includes a description of the preferred typical embodiment of the principles of the present invention, in which:
DESCRIPTION OF THE DRAWINGS
Figure 1 is a cross sectional top plan view of the clamp assembly Figure 2 is a vertical section substanti.ally along the line 2-2 of Figure 1.
Figure 3 is a front elevational view showing the r clamp assembly in use for supporting a pipe or conduit and associated structure.
In the drawings like characters of reference in-dicate corresponding parts in the different figures.
DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference should first be made to Figure 3 which, as an example, shows the clamp assembly collectively de-signated 10 secured to a supporting surface 11 and support-ing a vertical pipe or conduit 12 connected by means of junction 13, to further conduits 14 and the initial feed or entry conduit 15. On the upper end of the vertical pipe or conduit 12, there is secured a T connector 16 one branch of which leads to a conventional pressure reduction valve assembly 17 and the other arm of which leads to a U sh~ped connector 18 to which a conventional gas meter (not illus-trated) may be operatively secured, the whole being support-ed by the aforementioned clamp assembly 10.
Figures 1 and 2 show details of the clamp assem-bly. It consists of two separate substantially symmetri-cal members lOA and lOB. Each member is formed from a single sheet of mild steel and includes a substantially rectan-gular mounting flange 19 with a jaw support flange 20 ex-tending at right angles from the inner end 21 thereof.
A semi-circular or arcuately curved jaw 22 is formed on the distal ends of the portions 20 and it will be noted that the extremities 23 of these jaw portions terminate spaced apart from one another when the two portions 20 are in sub-stantial interfacial relationship one with the other, as snown in Figure 1.
In the present embodiment, the member lOB is pro-vided with drilled or other formed apertures 24 through which bolts 25 may extend into the supporting surface thus clamping member lOB firmly to th~ supporting surface.
The other member lOA is provided with transverse-ly situated elongated slots 26 by which it may be secured by bolts 27 extending through the slots and into the sup-porting surface 11. This means that the member lOA may move sideways relative to the member lOB, a distance defin-ed by the length of slots 26 thus enabling it to be moved apart from member lOB sufficiently to engage or disengage the conduit 12 between the jaws 22, toge~her with struc-ture associated with the conduit 12.
Once engaged between the opened jaws, the member 10A is moved towards member 10B so that the two jaws 22 embrace the conduit whereupon a cross bolt or clamp bolt 28 may be engaged through apertures 29 formed through the connecting portions or flanges 20. Tigntening this nut and bolt assembly 28 causes the two jaws to be clamped firmly around the conduit 12 whereupon bolts 27 may be tightened to secure the member 10A in position upon the supporting surface.
Removal of the conduit is a reversed procedure in which the nut and bolt assembly 28 is removed and the bolts 27 are slackened thus allowing the member 10A to be moved apart from member 10B thus permitting the conduit 12 to be withdrawn from between the jaws 22.
Alternatively, both members 10A and 10B may be provided with transversely extending elongated slots 26, if desired, thus giving greater flexibility to the mount-ing of the clamp assembly to the supporting surface.
Since various modifications can be made in my in-vention as hereinabove described, and many apparently wide-ly different embodiments of same made within the spirit and srope of the claims without departing from such spirit and scope, it is intended that all matter contained ln the accompanying specification shall be interpreted as illus-trative only and not in a limiting sense.
