Improvements in Horse Collars.
I, HENRY LAWRENCE GULLINE, of Elgin Street, in the Town of Granby, in the
County of Shefford and Province of Quebec, Dominion of Canada, Manufacturer, 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 more particularly to the rims of horse collars and has for its
object to produce a metal rim of simplified and improved construction.
The invention consists of a hollow metal rim formed complete of a single piece of
metal bent to the desired form and having a flange extending the full length thereof,
the rim possessing sufficient resiliency to allow of its being opened and closed at the
peak.
I will describe my said invention with reference to the accompanying drawing
forming a part of this Specification, in which like cymbols indicate corresponding
parts, and wherein,
Figure 1 is a rear view of a metal rim constructed according to my invention;
Figure 2 is a side view of same;
Figures 3, 4 and 5 cross sectional views of same respectively on lines 3-3, 4-4,
and 5-5, Figure 1, and
Figure 6 is a cross sectional view of a complete collar provided with the improved
rim.
The metal rim is formed of a single piece of metal a of such resiliency as will
allow it, when bent into the tubular body form shown and provided with the
tangential flange b extending throughout its entire length, to allow of its being
opened and closed at will, thus dispensing with any form of hinge or catch at
the throat portion and making the rim in one piece instead of two separate
sections.
It will be at once apparent that by my improvement a great saving in the cost of
manufacturing these metal rims is effected, besides the imparting of great additional
strength thereto, and the doing away with any possibility of breaking at the throat
portion through insecure or imperfect rivetting which might occasionally arise in the
construction of horse collar rims made in two halves and joined together at the throat
by a hinge or other attachment.
In order to manufacture my improved rim, I first cut the sheet metal into strips of
a sufficient width to enable them to be folded in a folding machine, to produce a
straight tube having a closed flange extending the full length thereof. One end of
this tube is then closed by a temporary plug and the tube filled with molten resin,
sulphur or other like material which is allowed to cool, this filling being to prevent
buckling when the tube is being bent, and to allow of the tube being bent while
cold.
The tube is then bent, midway of its length, over a mandrel of a diameter equal
to that required for the throat portion of the rim, and the ends are then, and pre-
ferably in the same operation, bent towards one another over a second mandrel of
such form as will produce the desired shape at the peak. As deem the means
for doing this folding and bending to be well within ordinary mechanical skill, I
have neither described nor illustrated them in detail.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. As a new article of manufacture, a horse collar rim formed of a single piece of
metal and of tubular form with a flange extending the full length thereof, as set
forth.
2. As a new article of manufacture, a horse collar rim formed of a single piece of
metal and of tubular form and such resiliency as to allow of the opening and
closing of same at its peak, as set forth.
3. As a new article of manufacture, a horse collar rim formed of a single piece of
metal and of tubular form with a tangential flange extending the full length thereof
and the rim being of such resiliency as to allow of the opening and closing of same
at its peak, as set forth.
