Improvements in and relating to Handles for use with Door and
other Locks.
I NIELS GEORG SÖRENSEN, of No. 11 Blasiholmstorg, Stockholm, in the Kingdom
of Sweden, Merchant, do hereby declare the nature of this invention to be as
follows
_
My invention relates to handles for use in connection with door and other locks in
which the usual turning of the knob is dispensed with and a movable projecting part
in the shape of a bent lever is provided in a fixed handle which part on being grasped,
by the hand is pressed into the said fixed handle itself, thus effecting the unfastening
of the door.
The improved handle is chiefly designed for locks of the kind described in the
specification accompanying a former application for Letters Patent, dated February 6th
1889 No. 2155 in which the bolt is actuated solely by its own weight; but the said
handle may also be used for common spring locks, as will be seen from the following
description.
In carrying the invention into practice; on each side of the door is fastened a plate
from which projects a hollow arm; the handle itself may either be placed on one side
of the end of the hollow arm or directly fixed to the upper side of the said end. It is
evident that the placing of the handle. on one side of the arm is in no way necessitated
by the construction itself, but only required for double doors for instance, in such
cases as when the narrowness of the door rail would bring the handle too near the
other door, or in the case of a single door-the door jainb.
When the handle is fixed to one side of the arm, the two parts are united by a
screw on which screw or axis is fitted a movable tube. To this tube is fastened a
lever hereinafter termed the "bolt lifting lever" which enters the lock through the
hollow arm and another lever hereinafter termed the "trigger" that passes up
the handle. A part of the last named lever passes through a slot to the outside of the
handle so that in grasping the said handle the one end of the lever is forced into the
said slot.

"trigger" is made to enter into the handle, the bolt lifting lever is set in motion
and lifts the bolt out of its socket in a vertical direction thus unfastening the door.
On releasing the trigger it moves back to its original position by its own weight the
trigger being so constructed that its centre of gravity is always on one side of the
centre of its axis of rotation. A bar is arranged in the handle which has for its
object to provide a stay for the handle (the said handle not being cast in one
piece). The said bar is either fixed to the end part of the arm or direct to
the arm.
The improved handle may also with advantage be connected with common spring
locks with bolts movable in a horizontal direction the handle will of course in such a
case have to be fixed accordingly, that is to say, on the door in a horizontal position
in order to give its lever which is to act direct upon the bolt a backward movement,
when the trigger is made to enter into the handle. The spring which acts upon the
bolt of the lock or if preferable a special spring for the purpose will always cause the
trigger, when released to return to its original position.
In a modification of the handle when applied to spring locks, the lever is dispensed
with and the movable tube or spindle mounted on the screw as axis or a solid axis
with bearings at each end is allowed to enter the lock through the hollow arm in
which case the usual knob spindle will be replaced by this movable tube. The trigger

page_text: which is fixed to the opposite end of the said tubular spindle has in this case a motion
parallel with the door thereby allowing the handle to be placed in any position
whatever in the same plane.
With regard to the position of the trigger on the handle it may be remarked, that
the trigger when placed on the inside of the handle near the door might in shutting
the said door by pulling it. easily be exposed to a pressure that would prevent the
bolts dropping down into the socket; this inconvenience can if found necessary-be
avoided by arranging the trigger so that it shall enter the handle from its opposite
side, that is to say;-so that the trigger shall be on the outside of the handle or on
the pushing side. It is evident that the handle and the trigger in this latter case
must either be turned downwards or a double motion must be given to the lever in
order to give the lever or its corresponding part a proper motion to work the spindle
in the right direction.
The improved handle offers many advantages over those hitherto known and now in
use; forms a steady support for the hand and at the same time performs the unlocking
operation of the door with the greatest ease, only by a slight pressure on the trigger,
whereas the handles now in use which consists of several different movable parts are
liable to get out of order after a comparatively short time in consequence of the
twisting and turning operation continually required of them.
The fitting of the improved handle to the door is an operation which require very
little skill and work the only thing necessary being two screws which pass through
the door and thus fix the two handles at the same time, whereas the fitting of most
handles, now in use, in consequence of its many loose parts requires great accuracy
and skill and a considerable amount of work.
The unlocking of the door with the improved handle is finally a much more con-
venient operation than with other handles the improved handle only requiring a slight
pressure or the grasping with the hand, whereas old handles necessitates a twisting or
turning movement with the hand.

Improvements in and relating to Handles for use with Door and
other Locks.
1, NIELS GEORG SÖRENSEN, of Stockholm, in the Kingdom of Sweden, Merchant,
do hereby declare the nature of this invention and in what manner the saine is
to be performed, to be particularly described and ascertained in and by the following
statement:—
My invention relates to handles for use in connection with door and other locks in
which the usual turning of the knob is dispensed with and a movable projecting part
in the shape of a bent lever is provided in a fixed handle which part on being grasped
by the hand is pressed into the said fixed handle itself, thus effecting the unfastening
of the door.
The improved handle is chiefly designed for locks of the kind described in the
Specification accompanying a former application for Letters Patent dated February 6th,
1889 No. 2155 in which the bolt is actuated solely by its own weight; but the said
handle may also be used for common spring locks as will be seen from the following
description.
In the accompanying drawing
Figures 1, 2 and 3 show a side view front view and vertical section respectively of
the improved handle.
Figure 4 is a horizontal section and
Figure 5 is a detailed section of the same.
Figure 6 is a modification.

page_text: Figures 7 and 8 show the trigger as having a motion parallel with the door.
Referring to Figures 1, 2 and 3 on each side of the door is fastened a plate a from
which projects a hollow arm b; the handle d itself may either be placed on one
side of the end of the hollow arm b (as shown in Figure 2) or directly fixed to
the upper side of the said end. It is evident that the placing of the handle on
one side of the arm is in no way necessitated by the construction itself, but only
required for double doors for instance in such cases as when the narrowness of the
door rail would bring the handle too near the other door or, in the case of a
single door, when the handle would come too near the door jamb.
When the handle is fixed to one side of the arm, the two parts are united by a
screw c on which screw or axis is fitted a movable tube e. To this tube is fastened a
lever hereinafter termed the "bolt lifting lever" which enters the lock through the
hollow arm and another lever g hereinafter termed the "trigger" that passes up
into the handle. A part of the last named lever g passes through a slot to the outside
of the handle so that in grasping the said handle the one end of the lever is forced
into the said slot.
The two levers ƒ and g form together a bent lever with a connecting tube or

the "trigger" is made to enter into the handle the bolt lifting lever is set in motion
and lifts the bolt out of its socket in a vertical direction thus unfastening the door.
On releasing the trigger it moves back to its original position by its own weight the
trigger being, as shown by the drawing, so constructed that its centre of gravity is
always on one side of the centre of its axis of rotation. A bar is arranged in the
handle which has for its object to provide a stay for the handle (the said handle not
being cast in one piece). The said .bar is either fixed to the end part of the arm i or
direct to the arm b.
The improved handle may also with advantage be connected with common spring.
locks with bolts. movable in a horizontal.direction, the handle will of course in such a
case have to be fixed accordingly that is to say, on the door in a horizontal position in
order to give its lever f which is to act direct upon the bolt a backward movement
when the trigger 9 is made to enter into the handle. The spring which acts upon
the bolt of the lock or if preferable a special spring for the purpose will always cause
the trigger, when released to return to its original position.
In a modification of the handle as applied to spring locks the lever is dispensed
with and the movable tube or spindle, mounted on the screw, as an axis or a solid
axis with bearings at each end is allowed to enter the lock through the hollow arm in
which case the usual knob spindle will be replaced by this movable tube. The trigger
which is fixed to the opposite end of the said tubular spindle, as shown in Figures 7
and 8 has in this case a motion parallel with the door thereby allowing the handle to
be placed in any position whatever in the same plane.
With regard to the position of the trigger on the handle it may be remarked, that
the trigger when placed on the inside of the handle near the door as shown in
Figure 1, might in shutting the said door by pulling it, easily be exposed to a pressure
that would prevent the bolts dropping down into the socket; this inconvenience can,
if found necessary, be avoided by arranging the trigger so that it shall enter the
handle from its opposite side, that is to say so that the trigger shall be on the outside
of the handle as shown in Figure 6 that is to say the trigger shall be so disposed as
to be next to the person when he desires to open the door. It is evident that the
handle and the trigger in this latter case must either be turned downwards or the
motion must be communicated to the spindle of the lock through a lever fixed thereon
as shown in Figure 6 in order to give the lever or its corresponding part an opposite
movement to that made by the trigger, so as to work the spindle in the right
direction.
The improved handle offers many advantages over those hitherto known and now
in use; it forms a steady support for the hand and at the same time performs the
unlocking operation of the door with the greatest ease, only by a slight pressure on
the trigger, whereas the handles now in use which consists of several different

page_text: movable parts are liable to get out of order after a comparatively short time in con-
sequence of the twisting and turning operation continually required of them.
The fitting of the improved handle to the door is an operation which requires very
little skill and work the only thing necessary being two screws which pass through
the door and thus fix the two handles at the same time, whereas the fitting of most
handles, now in use, in consequence of its many loose parts requires great accuracy
and skill and a considerable amount of work.
The unlocking of the door with the improved handle is finally a much more con-
venient operation than with other handles the improved handle only requiring a slight
pressure or the grasping with the hand, whereas the old handles necessitates a twisting
or turning movement with the hand.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a handle for doors and other purposes a hollow arm projecting from the door
and united with a handle, both parts being fixed to the door thus offering a steady
support for the hand in combination with a pivoted trigger lever which is arranged in
connection with and partly projects from a notch in the handle and which trigger by
being made to fully enter into the said handle either by means of its shaft entering
the trippet of the lock or by means of an arm acting direct upon the bolt of the lock
and projecting from the shaft of the same lever or by means of a bent lever actuated
by the lever causes the bolt to be removed out of the socket.
