A, A, represent the securing plates, one of which is attached to the door and
the other to the door-frame by means of screws inserted through the holes a,
therein, for that purpose. The plate A, is formed or provided, as shown in the
drawing, with a tube or cylinder B, on its inner edge, which extends to near its
upper and lower ends. This tube, with those B'; B', on the inner edge of the
plate A', which are at the upper and lower ends of this plate, is for the reception
and retention of the pintle C, the springs and mechanism for operating and con-
trolling the device. As is shown in Figures 2 and 3 of the drawing, the pintle C,
is made with its upper portion quadrilateral, or other than cylindrical. The pintle
is inserted into the chambers or tubes B', B, and B', and thus secures the plates A, A',
together. As seen, the ends of the pintle project somewhat above and below the
plates and these projecting ends are covered by ornamental caps D and D'. The
bottom of the power chamber or tube B, is formed, as shown in Figure 7, with a
number of depressions or recesses a', into which is received and retained the lug or
lugs a, on the collar E, which collar is formed with an annular flange a³, at its
lower portion which flange is of size to fit snugly in the bottom of the chamber B,
as clearly seen in Figure 5, and has secured thereto, by means of a hole a', or
otherwise, the lower end of the power-spring F.
The upper portion of the collar E, may be made smaller than its lower part and
may have a portion of the spring F, wound there around, or it may be made
without the smaller portion. The upper end of the spring F, the entire portion of
which is contained in the chamber B, is secured to a collar G, which is formed
with a square or other than cylindrical opening therethrough, to admit the rect-
angular, or other than cylindrical portion of the pintle C, and to permit it to move
freely thereon in the contraction aud expansion of the spring F, as will be presently
explained.
The collar G, fits in the chamber B, and has a periphery adapted to the inner
contour thereof.
The upper portion of the tube B', of the plate A', is formed with a depression or
recess of sufficient depth to accommodate the tension regulating plates H, H', the
former of which is formed with a squaro opening therethrough and 'a circular
periphery and teeth c, on its under surface, while the latter has teeth c¹, on its
upper surface and is formed with a circular opening and has a square exterior.
The plate H', fits into the square or bottom recess 6, of the tube B³, and is
thereby retained in a fixed position, while the plate H, rests normally in the upper
part b, of said recess, and is thus normally secured on top of the plate H¹, the
teeth of each engaging when in juxtaposition, and when in said position, are flush

page_text: with the top of the tube B', at the upper surface of said tube and over the upper
end of the pintle C, is secured the ornamental cap D¹, which is formed with a
hollow in its lower portion, and has on either side thereof a grooved,
clearly shown in Figure 14, into which fit the projections or ears d¹, on the
plate I, which plate is adapted to move the hollow c of the cap D', and has
two small rods, to connect it with the plate H, as is seen in Figures 2, 21
and 23.
-
Through the center of the plate I, is a hole d', into which is pivotally secured
the end of a screw, e, which is preferably counter-sunk and has its threads in
the upper portion of the cap D₁, as shown in Figure 2. Between the plates I,
and H, and around the pintle C, is secured a spring K, which holds the plates H
and H in contact and yet allows them to be disengaged, when desired, by the use
of the screw e.
.
When it is desired to increase the tension of the power spring F, it is only
necessary to turn the cap D', until a sufficient degree of strength of force is
obtained, and to lessen the same, to disengage the plates H, and H, by means of
the screw e. It will be understood that the cap D', is rigidly secured to the upper
end of the pintle by means of a rivet-pin e', which passes through a rivet tube e',
which is securely fastened in a hole in the upper end of the pintle and thereby more
securely holds it in place.
In Figure 11, I have shown a modification of the manner of regulating the.
tension of the spring in which case the screw e, is dispensed with. In this
modification I use a cap D³, similar in construction to D¹, except I omit the
opening through which the screw e passes and supply in the place of the collar E,
a collar E', which is similar in construction with the exception that the flange.a³,
is provided with teeth a', which engage with a pin or screw 1, which passea
through the side of the tube B. In using this modification to increase the
tension of the spring F, the same oporation as above described is performed and,
to lessen the same, the screw or pin l, is disengaged from the ratchet-toothed
collar E'.
Figure 21, is another modification of the manner of regulating the tension of the
power spring, and is closely similar to the construction shown in Figure 2, with the
following excoptions:-―
In Figure 21, the cap D, is formed at its lower end so as to be counter-sunk in
the chamber B', of the plate A', and the screw e', is threaded at the lower end
instead of being pivotally secured as in Figure 2.
In Figures 22, aud 23 and 24, is shown another modification in which the cap D',
is formed as in Figure 21 except that the upper part of the cap is provided with two
ports g, and 9, the port g, being deeper than 9, so that when the rod e, which has
its upper portion bent as at g², may be raised from the lower port to the upper one
the plates H, and Hare disengaged, the plate I being pivotally secured to the
lower end of the rod e³.
In order to remove from the collars G and E, and spring F, all the friction
incident to the contact thereof, with the inner surface of the chamber. B, I
sometimes provide the upper end of said chamber with an opening m, of sufficient
Bize to admit of the end of the pintle only, as is shown in Figure 25. In using
this modification the collare G and E, and spring F, are inserted therein from the
bottom.
Figure 31, illustrates my hinge for double-acting doors, and consists in the
construction, forms and operations above described, except that the plate A, has on
each edge a chamber B, for the pintles, springs and regulating mechanism as above
set forth.
In Figures 32 and 33 of the drawing I have shown an additional modification of
the manner of regulating the power spring.
In this modification the cap D' is formed with a hole therethrough into the lower
portion of which is embedded the spring K, which encircles the pintle and causes the
plates H, and H', to engage. The pintle passes through the hole in cap DỊ and has

page_text: formed in its upper end two horizontal grooves or depressions and, tho
depression being deeper than the depression z'.:.
These depressions or grooves are for the reception and retention of the upper
portion of the small rods d, which are connected at their lower ends to the upper
portion of the plate H. and are bent borizontally and may be united by twisting the
ends together or soldering the same so that they are united into a loop, which loop:
will fit into the horizontal depression z in which position the plates H. and H' are
engaged but when the said plates are desired to be disengaged the loop of the small
rods'd; is raised and placed into the depression =¹.
In this construction the upper portion of the pintle is preferably made of any
form other than cylindrical which form permits of the space for the reception of
the rods, between the sides of the pintle and the circular opening in the
cap D
Sometimes I may dispense with the entire mechanism for regulating the tension
of the spring F; and simply employ a wrench therefor, or other means; in which
case I use the ornamental caps for ornament only; but it will be understood, that
the pintle, spring F, collars G, and E, and the plates A, and A', having the
tubes B, B, Bare employed as before.
The operation of this hinge is as follows:-The plates A, and Al, are secured to
the door and casing in the ordinary manner and the tension of the power spring
regulated to suit the size and weight of the door, in any of the ways described in
the various modifications above set forth. When the door is opened it will, be
understood and is apparent by reference to the drawings that the spring. F, will be
coiled tighter and thereby contracted, and that in said contraction the collar G,
will be drawn down on the square portion of the pintle, and that the spring whose
tension has been properly adjusted to the weight of the door, will afterwards cause
the door to slowly close, in which operation the collar G, will rise again.on the
pintle to its former position as the spring uncoils.
In Figures 34 35 and 36 of the drawing is shown achingo for double acting, doors,
and an attachment thereto for holding the door in its normal or closed position and
to prevent it being blown ajar by a gust of wind, and yet to permit it to be readily
opened by a gentle pressure of the hand.
In this modification as in that illustrated in Fig. 31
any. of the constructions,
forms, and operations above described may be employed with the addition of one
or more catches P; each of which is made of a piece of material of proper
dimensions and preferably of the form shown in Fig. 35, and has formed on its inner
side a mortise o, having at its inner edge a recess.o', into which mortise and recess
fits a spring Q, which is somewhat smaller than the mortise, and when in position
rests its feet o, against the side of the chamber or tube B, which is preferably cut
away as at p. The catch P is formed with a number of slots. r, through which
are passed 'suitable bolts, or other devices for securing. it to the plate A, which
connects the two chainbers B, B, and has its edge opposite from the chamber B,
formed with an upper and under bevel s, s, or rounded so that, when the
appropriate plate A¹ pressed against either, bevelled portion (in engaging.or
liberating it) the catch P, will yield towards the chamber B, and be afterwards
pressed therefrom by its spring Q, thus offering enough resistance. to hold the door
closed against draughts of wind yet permitting it to be easily opened by hand..
