MENTS IN DRIVING CHAINS."
"IMPROVE-
My Invention is applicable to those driving chains known as Slater's bowl
chains, for which Letters Patent were granted to James Slater, on the 12th October
1864, No. 2515.
I connect the two outer links by a steel pin which I rivet in such a manner as to
keep it from revolving. I connect the two inner links by a tube or bush which
is rivetted firmly to them so that it cannot revolve. The pin connecting the outer
links passes through this tube or bush and works freely in it, the tube or bush
forming a long bearing, and taking the whole strain which formerly came upon the
inner links and caused them to work loose. The bowl which is placed between
the two inner links works or revolves on the tube or buslı.

IMPROVE-

page_text: have been granted to James Slater. In the said chains an anti-friction bowl or .
roller is mounted on each of the joint pins. I connect the two inner links by a
tube or bush which is riveted firmly to the said links so that it cannot revolve.
The pin connecting the outer links passes through this tube or bush and works
freely in it, the tube or bush forming a long bearing. The bowl which is placed
between the two inner links works or revolves on the tube or bush.
In order that my Invention may be fully understood, I will refer to the Sheet of
Drawings which I have attached hereunto. The said Drawings represent a short
length of chain made in accordance with my Invention. In the said Drawings a
are the outer links; b, the inner links; c, the pins, and d, the anti-friction bowls,
these parts being present in the ordinary chain. In the eyes of the inner links,
which eyes are made suitably larger than those of the outer links, I rivet or secure
tubes e which are made by bending sheet steel into a tubular form, or are otherwise
suitably made. The ends of the tube are firmly secured in the said links, so that
the tubes will not revolve in the eyes of the links, each pair of tubes connecting
together a pair of links. A bowl d is mounted upon each tube at a suitable stage
in the process of riveting the parts together, and revolves upon the said tube when
the chain is in use. The pins c are passed through the tubes, and the ends of tho
said pins are firmly riveted in the eyes of the outer links, so that they will not
revolve in the said eyes. It will be seen that when the chain is at work, cach tube
turns upon a joint pin, and as a consequence the wearing action formerly sustained
by the eyes of the inner links is sustained by the said tube, which having a long
bearing surface, is very little effected by such wearing action as compared with the
ordinary chain, and therefore the extension in the length of the chain and the
tendency of the joints to become loose and shaky are much less than in the case of
the ordinary chains. It will also be seen that the inner links being connected
together by the tubes, the parts of the chain are less liable to become loose. I
prefer to make the pins c and the bowls or tubes d of steel, but I do not confine
myself to the use of such material.
Having now fully set forth and indicated the nature of the said Invention, and
the manner in which I carry the same into practical effect, I would have it to
understood that I claim,-
First. The chain formed and composed substantially as set forth and indicated
herein before, and in and by the accompanying Drawings.
And, Secondly. Forming the chains to which my Invention relates with tubes or
bushes which are secured to the inner links, and are fitted to turn upon the joint
pins, substantially as set forth and indicated.
In witness whereof, I, the said Hans Renold, have hereunto set my hand
and seal, this Twenty-first day of September, in the year of our Lord One
thousand eight hundred and eighty.
