COMPLETE SPECIFICATION.
An Improved Squeegee or Scraper for Collecting Cream from the
Surface of Bowls and other Dairy Utensils.
I, EDWARD BELL RAPER, of 19, Low Ousegate, York, India Rubber Dealer, 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:-
The ordinary squeegee for scraping cream bowls consists of a strip of vulcanised
india rubber about five inches long, two inches wide and a quarter of an inch thick,
fastened into a handle of wood or metal, which handle may be of any shape that is
suitable to be grasped by one hand. The ordinary mode of fastening the india
rubber to the handle is this. In one edge of the handle a groove or slot is made
and in it the strip, cut from a sheet of vulcanised india rubber is inserted and
secured by screws or rivets which pass through the lips of the groove and through
the india rubber, the latter projecting beyond the wood or metal throughout its
length so as to come in contact with the bowl in scraping.
In the accompanying sheet of drawings Fig. I illustrates the ordinary form oi
squeegee, AAA being the handle, BB the india rubber strip and DDD the
rivets or screws.
My improved squeegee is similar in dimensions and shape to the one described
above both as regards the india rubber and the handle, but differs from it in two
respects, first in respect to the material of which the handle is made, and secondly
in respect of the mode of fixing the india rubber to the handle.
1. I use metal only not wood for the handle, and preferably cast iron as being
best adapted to the process described below.
2. In attaching the india rubber to the handle I dispense entirely with screws
or rivets and make the attachment by the process of vulcanising the india rubber.
The vulcanising is performed in the usual manner in a chamber heated by steam.
I apply the strip of india rubber in a raw unvulcanised state to the metal handle,
either using a groove in the metal in which to insert the rubber or applying the
rubber to the ungrooved edge of the handle and wrapping it slightly over onto the
surface of the metal to give it a better hold, and in either case I put it through
the vulcanising process while maintained in that position. I can thus make so
intimate a joint between the india rubber and the metal that no interstice is left
for liquid or dirt to penetrate betwixt them. Herein lies the advantage of my
form of squeegee. Fig. I referred to above represents the improved squeegee,
when made with a groove, except that the rivets 1 DD are absent in my squeegee,
the vulcanising being sufficient to unite the india rubber to the metal, as explained
above. Fig. II. illustrates my squeegee when made in the second mode riz:-
without a groove, A A A being the metal handle, the dotted line a showing the
extremity of the handle where it is embedded in the india rubber. BB is the
india rubber.

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
A squeegee or scraper for cream bowls and other dairy utensils in which a
strip of india-rubber is attached by vulcanising to the metal handle substantially
as above described.
