IMPROVEMENTS IN DOUBLE- ACTION BOX SPRING HINGES FOR SWING DOORS
Year: 1861

page_text: LETTERS PATENT to John Whines, of Pimlico, in the County of Middle-
sex, Builders Foreman, for the Invention of "IMPROVEMENTS IN DOUBLE-
ACTION BOX SPRING HINGES FOR SWING DOORS."
:
Sealed the 6th December 1861, and dated the 8th June 1861.
PROVISIONAL SPECIFICATION left by the said John Whines at thre
Office of the Commissioners of Patents, with his Petition, on the 8th
June 1861.
I, JOHN WHINES, of Pimlico, in the County of Middlesex, Builders' Fore-
man, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DOUBLE-ACTION BOX SPRING HINGES FOR SWING DOORS," to be as follows:-
The spring hinges are constructed with a circular disc, in which is mounted
a pair of rollers, working on a circular double inclined descending plane or
dise kept in contact with the pair of rollers by a spiral spring. The disc with
rollers has a horizontal reciprocating motion imparted thereto by the action
of the door, to the bottom of which is attached a metal shoe with centre pin
and lever arm carrying a roller, which takes hold of a cam secured to disc with
rollers and working on a stud or pin. The descending incline plane or disc
is formed with a projecting lug on each side to work in vertical slots in
metal box.

TO ALL TO WHOM THESE PRESENTS SHALL COME, Joun
WINES, of Pimlico, in the County of Middlesex, Builders' Foreman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Eighth day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said John Whines, Her special licence that I, the said Jolin
Whines, my executors, administrators, and assigns, or such others as I, the
said John Whines, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and-Isle of Man, an Invention--for
"IMPROVEMENTS IN DOUBLE-ACTION Box SPRING HINGES FOR SWING DOORS," upon
the condition (amongst others) that I, the said John Whines, my executors
or administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Whines, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement thereof, reference being had to the Drawing hereunto
annexed, that is to say:-
The spring hinges are constructed with a circular disc in which is mounted
a pair of rollers working on a circular double incline descending plane or disc
kept in contact with the pair of rollers by a spiral spring. The disc with
rollers has a horizontal reciprocating motion imparted thereto by the action of
the door, to the bottom of which is attached a metal shoe with centre pin and
lever arm carrying a roller, which takes hold of a cam secured to disc with
rollers, and working on a stud or pin. The descending incline plane or disc

page_text: is formed with a projecting lug on each side to work in vertical slots in
metal box.
My Invention will be fully and clearly understood by reference to the
Drawing hereunto annexed, and the following description of the same.
Figure 1 is a plan, and Figure 2 is a sectional elevation through the line
A, B, of Figure 1; Figure 3 is a separate view of the circular double incline
descending plane or disc; and Figure 4 is a view shewing the relative positions
of the incline plane and revolving disc with rollers when the door is closed.
A is a metal box in which the pin or stud F is secured by the nutt N; D, D,
is the revolving disc with rollers L, L, working on the double incline descend-
ing plane or disc C, with a lug or pin working in vertical slots in metal box A,
which said dise is kept in close contact with the rollers L, L, by means of the
spiral spring K; J, J, centre pin with lever arm carrying a roller H, and
working in metal step E; B, a metal shoe firmly secured to centre pin J and
bottom of door; G, cam, working on centre pin F, and abutting against lugs
P, P, cast on revolving disc D, D. Now, the action of the whole combined is
thus: The opening of the door causes the lever arm J, carrying the roller II,
to move the cam G through a portion of a circle, and with it the revolving
disc D, D, and rollers L, L, which travel up the inclined disc C, C, causing it
to descend and compress the spiral spring K; the same action takes place
whichever way the door is moved, and when the door is left to itself the inclino
disc C and revolving disc D, with rollers L, L, will return to the position
shewn in Figure 4, and the door will be closed.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my improve-
ment in double-action box spring hinges for swing doors, the general construc-
tion of such springs and the particular combination of their several parts,
together with the method of action thereof herein-before described and
represented in the Drawing hereunto annexed.
In witness whereof, I, the said John Whines, have hereunto set my
hand and seal, this Twenty-fifth day of November, One thousand eight
hundred and sixty-one.
JOHN WHINES. (L.S.)
