PROVISIONAL SPECIFICATION.
Improvements in Springs for Doors and analogous articles, and in
Adjustments and Checks for Preventing Slamming.
I, ROBERT ADAMS, of 67 Newington Causeway, London S.E., Engineer do
hereby declaro the nature of this said invention to be as follows :-
Whereas in the Specifications of Letters Patent, No. 12,644, I have described
certain improved methods of fitting springs and checks to doors, in which the
compression of the spring takes place on opening the door, with a decreasing
leverage; the expansion of the spring causing the door to close again; and, when
checks are also fitted to prevent slamming, such checks act in concert with the
springs. And whereas further improvements in such springs and checks are
described in my later Specifications, Nos. 27188, 4447, 268507, and 150788
Now the object of my present invention is to effect further improvements in
such door springs and checks, more especially in the spring and check shown in
No. 1507, Fig. 14, in which figure a rectangular frame is shown for com-
municating the closing force of the spring and the retarding forco of the door
check; and in adapting the cam thereto; the slotted form of which cam is shown
in 1507, Fig. 17, and the solid form being shown by dotted lines in Fig. 7 of the
same Specification.
The cam and pivot I form in one as hitherto, and add a pair of rollers to the
end transverse bar or bars of the rectangular frame, the rollers being placed in
such a position that the cam is always in contact with one of the rollers while the
door is open, and with both of the rollers when the door is closed.
I so form the cam or cams that it or they are capable of operating upon the
rectangular frame, when the door is closing, and thereby suitably acting upon
the check.
The rectangular frame may be made to extend beyond the pivot, and enclose the
pivot and cam within its area, as in Fig. 14 of 15078, or it may be shortened, the
position of the cam being reversed, which enables me to place the pivot nearer
the end of the box, and also, if necessary, to remove the frame from the box as
well as to remove the spring from the frame without disturbing the cylinder,
or to remove the cylinder without removing the frame, and without taking down
the door.
I also fit the box containing the spring and check with improved means of
adjustment. For this purpose I fit a staple or frame to the floor, which holds the
box in position but allows of a slight angular movement in either direction, so as to
bring the door in alignment with the transom, when closed. For the same purpose
some of the holes through which the screws pass are elongated or slotted.
The fluid check may be placed as shown in Fig. 14 of 15078, or near to the
pivot; the connections being modified accordingly; the cylinder or the piston and
rod being in some cases cast in one with the rectangular frame.
For fitting double acting doors I sometimes cast the double acting cam on one
level, and sometimes on two levels, upon the pivot; modifying the two portions to
secure perfect action, and extending the angles of operation.
For single acting doors the cam is modified to suit the same, so as to act in one
lirection only.
In fitting doors or windows pivoted in the centre, the same may be arranged to
urn the entire circle; and in fitting ordinary single and double acting doors, the
nvention is arranged to operate at any angle to which the door is capable of being
pened.
The invention may be modified so as to dispense with the check, thus forming

page_text: simply a spring hinge; or the check may be fitted without the spring, thus forming
a combined hinge and slam check only.

COMPLETE SPECIFICATION.
Improvements in Springs for Doors and analogous articles, and in
Adjustments and Checks for Preventing Slamming.
I, ROBERT ADAMS, of 67 Newington Causeway, London, S.E. Engineer, 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 following
statement:-
Whereas in the Specifications. of Letters Patent, No. 12044, I have described
certain improved methods of fitting springs and checks to doors, in which the.
compression of the spring takes place on opening the door, with a decreasing
leverage the expansion of the spring causing the door to close again; and, when
checks are also fitted to prevent slamming, such air, oil, or other fluid checks act
in concert with the springs. And whereas further improvements in such springs
and checks are described in my later. Specifications, Nos. 271885, 4447**, 268587,
and 150789.
Now the object of my present invention is to effect further improvements in such
door springs and checks, more especially in the spring and check shown in
No. 1507, Fig. 14, in which figure a rectangular frame is shown for com-
municating the closing force of the spring, and the retarding force of the door
check; and in adapting the cam thereto; the slotted form of which cam is shown
in 150788, Fig. 17, and the solid form being shown by dotted lines in Fig. 7 of the
same Specification.
The cam and pivot I form in one as hitherto, and add a pair of rollers to the end
transverse bar or bars of the rectangular frame, the rollers being placed in such a
position that the cam is always in contact with one of the rollers while the door is
open, and with both of the rollers when the door is closed.
I so form the cam or cams that it or they are capable of operating upon the
rectangular frame, when the door is closing, and thereby suitably acting upon
the check.
The rectangular frame may be made to extend beyond the pivot, and enclose the
pivot and cam within its area, as in Fig. 14 of 1507, or it may be shortened, the
position of the cam being reversed, which enables me to place the pivot nearer
the end of the box, and also, if necessary, to remove the frame from the box as
well as to remove the spring from the frame without disturbing the cylinder,
or to remove the cylinder without removing the frame, and without taking down
the door.
I also fit the box containing the spring and check with improved means of
adjustment. For this purpose I fit a staple or frame to the floor, which holds the
box in position but allows of a slight angular movement in either direction, so as to
bring the door in alignment with the transom, when closed. For the same purpose
some of the holes through which the screws pass are elongated or slotted.
The fluid check may be placed as shown in Fig. 14 of 150788, or near to the
pivot; the connections being modified accordingly; the cylinder or the piston and
rod being in some cases cast in one with the rectangular sliding or other frame.
For fitting double acting doors I sometimes cast the double acting cam on one
level, and sometimes on two levels, upon the pivot; modifying the two portions to
secure perfect action, and extending the angles of operation.
For single acting doors the cam is modified to suit the same, so as to act in ono
dination only

page_text: In fitting doors or windows pivoted in the centre, the same may be arranged to
turn the entire circle, by a modification of Figs. 13 and 14 of No. 150788, or a
travel of 180° in either direction and return; and in fitting ordinary single and
double acting doors, the invention is arranged to operate at any angle to which the
door is capable of being opened.
The invention may be modified so as to dispense with the check, thus forming
simply a spring hinge; or the check may be fitted without the spring, thus forming
a combined hinge and slam check only.
"
In this Specification the words "door" and "doors" are (for the sake of brevity)
intended to include all other analogous articles to which my invention may be
applied; and the words "door springs are intended to include door springs
combined with checks, and door springs without checks, and with or without other
appliances herein described.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Fig. 1 is a plan, and Fig. 2 an elevation, partly in section, showing my improve
ments, as applied to the form of door spring and check shown in Fig. 14 of
No. 150788.
These improvements consist in adding rollers 1, 1, to the sliding frame 2; also in
an improved form of cam 3, to receive the thrust of the rollers; and an improved
form and arrangement of check cam 4, which prevents the recoil or backlash of the
frame 2, when the door is just closing, by the contact of the cam 4 with the face 5,
attached to or forming part of the frame 2. The cams 3 and 4 are formed in one
with the pivot 6. The cam 4 may be placed below the cam 3 (as shown in Fig. 2)
or above (as shown by dotted lines in Fig. 2) or otherwise; the check face 5 being
correspondingly placed to meet the cam 4. 7 is my check, analogous to that shown
in Figs. 1 to 5 of 150788 to prevent slamming of the door. The spring 10 is
regulated by means of the nut 8 working on the screw 11. The end of this screw,
where it enters a socket 12 formed in the frame, is squared, or otherwise formed to
prevent it turning with the nut; the socket being formed to correspond therewith.
15 is the fence plate against which the spring presses. 19 is ་་
8 set-open "nut,
and 20 is a disc which may be cushioned; and which are used in setting open tho
door, in a similar manner to that hereinafter described.
The travelling distance piece 30 acts as a sliding guide supporting the end of
the spring and frame and thereby relieving the check piston of its weight.
Fig. 3 is a plan and Fig. 4 an elevation (both partly in section) showing another
method of forming the cam and bearing surfaces. 13 is a sliding pressure plate
fitted to the upper end of the frame 2. This plate is held in contact with the bar
by the pressure of the spring 10. As the cam 3 turns with the pivot 6 on opening
the door, one end of the pressure plate enters one of the slots 14, provided for that
purpose. The sectional form of the cam is shown in Fig. 3, and the sectional form
of the sliding plate 13 is shown in Fig. 4. The lower end of the pivot 6 works
in a socket formed in the case 9, as shown in Fig. 4.
Fig. 5 is a plan view of the pivot end of the improved door spring, adapted to
operate upon single-acting doors. The sliding frame 2 is fitted with a single
roller 1 to take the thrust of the cam 3. This cam 3 and also the check cam 16
revolve with the pivot 6. The curved end of the can 16 slides against the check
face 17 attached to, or forming part of the sliding frame 2. The contact of the
faces of 16 and 17 prevents backlash, in an analogous manner to the action of the
cam 4 and face 5, hereinbefore described.
Fig. 6 shows one end of a door spring, illustrating an adaptation of my invention
for retaining doors partly open, when required. 18 is an additional sorow attached
o the frame 2, or formed in one with the screw 11. 19 is a nut threaded on the
crew 18. 20 is a rubber or other elastic buffer or cushion which is sometimes
sed with the nut for reducing concussion when the door reaches the arranged
position.

page_text: Fig. 7 shows another method of arranging my improved springs and checks for
double acting doors. The frame 2 is extended so as to enclose, within its horizontal
area, the cams and check. The working can 3 and check cam 4, are placed
between the pivot 6 and the end of the box 9. 5 is the check face formed in the
sliding frame. The action of the cam 3 upon the rollers 1, 1, and spring 10; is
similar to those above described; some of the parts being merely reversed. The
piston rod of the check is attached to the sliding frame 2 by a screw 21. If the
door is required to be set partially open, the screw 18, nut 19 and elastic or other
buffer 20 may be added, severally operating as before described in relation to
Fig. 6.
Fig. 8 shows a modification of the door spring shown in Figs. 1 and 2; the check
cam 4 and check face 5 being omitted.
Fig. 9 shows a modification of Fig. 7, in which the check cam and face are also
omitted.
'
A similar arrangement may be applied to Fig. 10, in which figure another
modification is shown; the plain end of the adjusting screw 11 being carried
through the lower end of the sliding frame 2, where the squared end fits into a
socket 12.
Fig. 11 shows another modification of my invention. 9 is the outer case or box.
23 is a double-acting cam formed' in one with the pivot 6. The cam is formed with
two acting faces and two sets of teeth meshing with corresponding faces and
teeth 24 formed in the frame 22. For single-acting doors one half only of the cam
is required. 25 is a stationary thrust block. The frame 22 is formed with a
conical projection 27 which works in a conical hole in the cruciform block 28. The
frame 22 may be pivoted or otherwise fitted to the regulating screw 11 at 26.
29, 29, are two screws tlirended into the block 28, by which the alignment of the
door is regulated; but 'other adjustments may be used. When the door is opened
the cone 27 follows the motion of the frame 22 without leaving the block 28. The
frame may be modified by substituting therefor a single or double plate, serving the
same purpose, and acting on the same principle.
Figs. 12 to 34 illustrate various methods of adjusting, the boxes so as to secure
the correct alignment of the doors to which they are fitted; the boxes being fitted
in 'adjusting-frames; which may be screwed to the floor.
Fig. 12 is a plan view, showing one method of adjustment;
Fig. 13 is a section on the line a b; and
Fig. 14 is a section on tlic line cd; the enclosed spring box being shown in
ontline.
The frame consists of a head piece 31, and foot-piece 32, muited by a waist
piece 33; all formed in one and secured to the floor by screws or otherwise. 9 is
the door spring box placed in the frame. 34 is the cover plate (omitted in Fig. 12),
35 is a lug on the frame, and 36 is a slotted plate on the door spring box. 37 is an
adjusting screw. 38 is a centre-boss cast on the spring box, for which a hole is
provided in the head' piece 31, as shown in Figs. 13 and 14. The plate 36 may
sometimes be dispensed with, and a slot may be formed in the plate 34 to receive
the upper end of the screw. By shifting the box upon the centre 38 until
the door is in alignment, and then tightening the screw 37, the door is readily
adjusted.
Fig. 15 is a plan view showing another method of adjusting the spring box.
Fig. 16 is a section on the line e f; and
Fig. 17 is a section on the line gli:
In Fig. 15 the cover plate 34 is shown partly broken away, to show the pivot
bearing plate 39, and the recess 68 in the box, to provide for the motion of the box
about the centre 38: In Fig. 17 the method of recessing the lead of the screw 37
above the slot 35 is shown?
Fig. 18 illustrates another modification, the spring box 9' being covered in byla
plate 40, under the top platè 34, in which the slot 35 is formed.
The arrangements for adjustment may be further modified by making the head

page_text: piece 31 separate from the foot piece 32, as shown in Figs. 19, 20 and 21; Fig. 19
being a plan view of the head piece 31, Fig. 20 a plan view of the foot piece 32,
and Fig. 21 a side view of Fig. 20. The separate parts are screwed to the floor in
position for the spring box, and a set screw at 37 passes through a slotted lug
attached to the spring box, or vice versa.
Figs. 22, 23 and 24 illustrate another arrangement for the same purpose; Fig. 22
being a plan, Fig. 23 an end view, and Fig. 24 a section on the line ik of Fig. 23.
35 is a slot formed in the end 32 of the frame; 37 is the set screw attached to the
end of the spring box 9, whereby the position of the spring box is adjusted. This
may be further varied as shown in Figs. 25 and 26; Fig. 25 being a plan, and
Fig. 26 an enlarged section on the line lm of Fig. 25. 35 is a slotted lug cast on
the spring box 9. 41 is a bolt and nut, capable of sliding in and on the slotted
lug 35. 42 is the regulating screw meshing in the head of the bolt 41.
Figs. 27 to 34 illustrate other methods of adjustment. Fig. 27 is a plan and
Fig. 28 an end view, showing short screws 43 fitted to the spring box 9.; by turning
these screws the position of the spring box is readily adjusted, by their contact
with the frame 32.
Fig. 29 shows a method of adjustment by means of a worm 44' meshing into
teeth formed on the end of the spring box 9. The worm axle may be clamped
between the sides of the frame 32, as shown by solid lines, or it may be supported
by lugs cast on the frame, as shown by the dotted lines, and secured by wedges.
In Fig. 30 a serrated block 45 is shown meshing into serrations cast on the box 9;
the block 45 being held in a groove formed in the frame.
Figs. 31 and 32 illustrate a method of adjustment by means of wedges; Fig. 31′
being a plan and Fig. 32 a sectional elevation on the line n o. The wedges 46
may be tongued and grooved or pinned to prevent displacement. One of the
wedges may be cast on the box 9 or frame 32, or they may be separate, as
shown.
Fig. 33 shows another method of adjustment by means of a screw 46 running
through the box 9, and impinging against curved surfaces formed in the frame 32°;
or a screw 47 (Fig. 34) may be used with a parallel sided frame.
Fig. 35 is an elevation and Fig. 36 a plan, showing certain improvements in the
construction of the door spring described in the Specification No. 2685%, as fitted
to a right hand door. 48 is the door and 49 the lintel or transom. 50 is a hexagonal
bracket. 51 is a forked arm pivoted to the bracket 50 at 52. 53 is the long arm
bracket to which the long arm 54 is pivoted. 55 is a reversed fork forming part
of the long arm and fitting into tho fork of the arm 51. 56 is the cyliuder con-
taining the spring and air check, (as described in 268587), 57 is the piston rod
usually pivoted to the reversed fork of the long arm at 58, except when the spring
is found to be too powerful, in which case the leverage is decreased by pivoting the
piston rod 57 to the forked arm 51 at 61 as shown, or in any other suitable position
for adjusting the leverage to the work. The return fork of the long arm 54 has
three transverse holes 58, 59 and 60, passing through both sides of the fork. The
holes 59 and 60 form centres for the long arm pin, either of which may be used,
according to the leverage required and the angle to which the door is to be
opened.
For a right handed door (as shown) the spring cylinder is attached to the lintel,
and the long arm bracket to the door. For a left handed. (outside) door the
cylinder is fixed to the door and the long arm bracket to the lintel; but it is obvious
that the fittings can be modified or they can be connected up in the reverse
way, so that the cylinder may be fitted to the door or to the lintel for both
right and left handed doors, inside or outside.
Fig. 37 shows a modification of my improved door spring and check, for single
acting doors. G is the pivot. 62 is a power arin fast on the pivot. 63 is a forked
connecting rod pivoted to the power arm at 64. The two arms of the connecting
rod or rods pass outside the cylinder 56, and are pivoted to an inner cylindur 67
at 66, the connecting pins passing through slots 69 in opposite sides of the cylinder.

page_text: The lower end of the inner cylinder or piston is fitted as a check. 10 is the
power spring. 70 is a piston rod, passing through the cylinder cover or fence
plate. 19 is a set-open nut and 20 is a buffer (as hereinbefore described) for
retaining the door partly open, as required.
Fig. 38 shows a modification of Fig. 37. The power arm 62 is pivoted at 64 to
the oscillating piston rod 71, the latter being pivoted to the piston at 65 (shown
by dotted lines); or instead thereof the cylinder itself may be pivoted. 19 is a
set-open nut and 20 is a spring acting as a buffer to the set-open nut. A slotted
cover or fence plate is fitted to the cylinder.
Fig. 39 shows another arrangement of my door spring and set-open combination,
with or without an air check. 72 is a bracket attached to the door frame. 56 is
the cylinder, having slots 69 on opposite sides. Double connecting rods 63 are
pivoted to the piston by pins at 66 passing through the slots 69, as in Fig. 37.
19 is a set-open nut and 20 a buffer (as bereinbefore described). This form of
spring is more especially adapted for fixing to the middle style of a door, and is
also a modification of Figs. 25 and 35 in No. 444788.
It is obvious that many of the various constructions, arrangements and
modifications hereinbefore described are interchangeable, and that the combinations
of the several parts may be varied in many useful ways, without departing from
the general principles involved therein.
