COMPLETE SPECIFICATION.
Improvements in Knobs or Handles for Stoves, Ranges, and
the like.
.
I, HEINRICH GÖSSER, of Iserlohn, Westphalia, in the Empire of Germany, Manu-
facturer, do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to knobs which are secured in lieu of the knobs or handles,
heretofore employed, to stoves, ranges, and the like. and is designed to improve the.
construction of the same so that they can be made in a simple manner and shall be
very durable. Such knobs or handles are usually provided with an internal screw-
thread by means of which they are screwed upon a spindle or pin rivetted to the
door or other part of the stove, range or the like; but as they consist of thin sheet
brass great difficulty has hitherto been experienced in forming a durable screw-thread
in their neck or shank without greatly increasing the prime cost.
In the accompanying drawing,
Figure 1 is an elevation, and,
Figure 2 a section of the improved knob or handle whilst,
Figure 3 shows sections of the several parts constituting the same.
The improved knob or handle consists of two main parts, namely the ball A and the
neck or shank B, the latter being made of two parts a and b. The front part a of
the neck or shank is provided with a flanged edge i which serves as a seat for the
ball A, in order that, when all the parts are simultaneously soldered together, the
said ball and front part will be firmly connected. The edge of the said front
part a is tent inwards so as to form a kind of collar into which fits a nipple s on
the rear part b. All the three parts, namely the ball A, the front part a and rear
part of the neck or shank are made in the known manner by means of a swaging
or stamping machine. Then the parts a and b of the neck or shank are joined, the
nipple s being inserted into the collar r; the ball A is next put upon the seat i;
granular hard solder is strewn into the collar at rand on the aforesaid seat i and
the whole is heated simultaneously until the solder flows. The solder which runs
into the annular space at r and the metal at r and at s, form a swell or reinforce
of such thickness on the inner surface of the neck or shank (Figure 2, at r s¹),
that a screw-thread of the required strength can be neatly cut into the same and
that the neck may be turned exteriorly to prevent the joint between the front
part a and the rear part 6 being easily noticeable. Prior to the cutting of the
aforesaid screw-thread the bottom in the nipples of the rear part b must be cut out
or otherwise removed.
b
A knob or handle manufactured as hereinbefore described looks well outside, has
a durable screw-thread (not cut in thin sheet metal), and it can be produced without
considerable extra cost as compared with the knobs hitherto employed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is;
A knob or handle of sheet metal, comprising the hall A and the neck or shank B
formed of two parts a and b, the former part a being provided below with an inwardly

page_text: hent edge i, and the latter part with a nipple s; for the purpose of forming by
means of the hard solder used for connecting the said parts a swell or reinforce
ats in which a strong screw-thread can be provided.
