COMPLETE SPECIFICATION.
Process of Securing Trimmings upon Tubular or other Bodies.
I, PETER GENDRON, of 1413, Walnut Street, in the City of Toledo, County
of Lucas, State of Ohio, United States of America, Manufacturer, do hereby
declare the nature of my invention for "PROCESS OF SECURING TRIMMINGS UPON
TUBULAR OR OTHER BODIES," 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 new and useful improvements in a process of
applying malleable trimmings to cylindrical or polygonal bodies; and the invention
is designed to be used in the manufacture of carriages and wagons in applying
such trimmings to whiffle-trees, axles, and other similar bodies.
In the present state of the art, such trimmings are applied by clamping them
in position by means of clamping bolts, by placing them upon the body when
hot and allowing them to shrink tight, or by driving the trimmings on the
tapering part of the body. My method has for its object the overcoming the
objections to which these former methods are subject; and consists in applying
the metal trimmings loosely upon the body to which they are to be secured, and
then applying pressure upon the outside of the trimmings sufficient to tightly
compress the trimmings upon the body against danger of displacement.
In the drawings which accompany this Specification,
Fig. 1 shows a tubular body to which a malleable trimming is desired to be
secured.
Fig. 2 shows the metal trimming to be applied upon such a tubular body.
Fig. 3 shows a whiffle-tree with the metal trimming in place.
Fig. 4 shows the manner of applying the dies and compressing the trimmings
upon the body.
Fig. 5 shows a polygonal body having trimmings applied upon it by my process.
A is a tubular body, such, for instance, as the body of a whiffle-tree, upon which
the metal trimmings B, or whiffle-tree hooks are designed to be secured. This
hook has the usual tubular portion, being made of slightly larger diameter than
the outside of the body A, and is made of malleable casting. This trimming I
place in its desired position upon the body A, as shown in Fig. 3, and then place
it between dies C, which latter are made of a shape to conform to the shape of
the trimming; pressure is then brought to bear upon the dies in any suitable
manner, as by means of a hydraulic press, or leverage, until the pressure is
sufficient to reduce the inner diameter of the tubular portion of the trimming,
setting it tightly upon its adjusted position on the body. This pressure would be
sufficient to prevent any danger of displacement from strain upon the trimming, the
only way in which it could be displaced would be to break it.
The result of this pressure is to press the trimming slightly onto the body,
forming a seat therein, such as a in Fig. 1. This, of course, is but a slight
indentation but sufficient to prevent any possible lateral movement.
D shows another form of trimming which it is sometimes desired to place upon
tubular bodies. E is a trimming as applied to a body of polygonal shape.
While I show my invention as applied to tubular bodies, it is apparent that it
may be applied to solid bodies as well, and I do not desire to limit myself to the
application of my process to tubular bodies.
When pressure is applied upon the malleable trimming in this way, the diameter
being lessened, the casting is materially strengthened being compressed and
thickened, so that it not only forms a tighter joint than by other methods previously
used; but also lengthens the life of the casting; and there is no danger of breaking
it by blows or otherwise in applying it.

page_text: 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 :
The process herein described of securing trimmings to tubular or other bodies,
consisting of placing a trimming in position on a tubular body and compressing the
same into the metal of the body, substantially as described.
Dated this 13th day of December 1890.
