Filed Apr. 22, 1960, Ser. No. 24,055
8 Claims. (Cl. 248-63)
The present invention relates to pipe hangers, and per
tains more particularly to a pipe hanger for hanging pipe
along a Wall or ceiling.
In modern building practice it is common to hang one
or more pipes along a wall or ceiling, and various types
of hangers have been developed for facilitating the hang
ing of such pipe.

pipes which it is intended to hang by means of the present
invention, for example, the pipe 13 of FIGS. 1 and 3.

three or more pairs of notches, and for encircling even

The invention provides a simple, inexpensive and sturdy
pipe hanger, one which can be easily mounted on a wall,
ceiling or structural member of a building, and which
can be easily and properly used even by relatively un
skilled laborers. There is no danger of the retaining
clips becoming accidentally dislodged, although they may
be easily removed as explained previously herein, in
the event ‘that it should become desirable to remove or
reposition any of the pipes mounted on a hanger A
embodying the invention.
While I have illustrated and described a preferred
embodiment of the present invention, it will be under
stood, however, that various changes and modi?cations
may be made in the details thereof without departing
from the scope of the invention as set ‘forth in the
appended claims.
