page_text: casting D is then placed upon the upper ends of the said pipes with the apertures d
properly matching the threaded holes c.
Threaded thimbles E provided at their upper edges with diametrically opposite
slots e for the reception of a proper tool for forcing the thimbles into place, are
then passed through the holes d¹ and screwed into the threaded holes d'of the upper
chamber and the holes c of the pipes C, thus connecting the said chamber with the
pipes.

The thimbles are forced into the holes dc until the bottom of the slots e are
approximately even with the inner floor of the casting or chamber D.
By the use of proper expanding mechanism not shown projected through the
holes d' the thimbles are then expanded into the holes d to properly secure the
pipes and casting together, thus insuring a proper steam tight joint.
The holes are then closed by the threaded plugs F having rectangular slots f
into which a proper corresponding tool is operated.
An ordinary open-work or ornamental plate G is then placed upon the top of
the casting D and the radiator is complete, and ready to be placed into position
and connected with a steam generator not shown. To this securing means we
attach much importance. It is inexpensive, readily operated and efficient.
also attach importance to the construction of the base in its relation to the travel
of the hot-water or steam which we will now describe.
We
Transversely across the inner portion of the base between the first and second
pipes or series of pipes (or between the second and third in radiators of large size)
is a vertical diaphragm or partition H. In this partition H is formed an exit
aperture . From this aperture or from the edges of this cut away portion h
extends a horizontal partition I which forms a hot water or steam way I from the
parth to the exit a of the base, entirely separate from the water inlet, in other
words, the partition H divides the interior of the base into two chambers_of
unequal area A1 A2 and the horizontal partition cuts off from the chamber A³, a
space to form the exit steam or water way I'
The hot water or steam passing in at a into the chamber A2 is forced upward
through the first pipe or series of pipes C into the large chamber of the casting D
thence down through the remaining pipes to the chamber A¹ of the base and thence
through the way I to the outlet a and back to the generator or elsewhere.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
1. In a radiator, the combination of a hollow base, provided with a vertical
partition, cut away to form an outlet a horizontal partition conforming to the
cut-away portion of the outlet partition and forming one of the walls of said
outlet and pipes C, with an upper chamber connected to said pipes substantially as
described.
2. In a radiator, the combination of a hollow base and pipes having threaded
apertures c with the hollow casting having threaded apertures d, d the threaded
thimbles screwed into the holes d, c and expanded, and the threaded plugs F
operating in the holes d' whereby the upper chamber is made steam or water-
tight substantially as and for the purposes set forth.
