IMPROVEMENTS IN DUPLEX LOCKING AND BOLTING APPARATUS
Year: 1885

page_text: SAMUEL HALL, Strand Arcade, Derby, in the County of Derbyshire, (Trading as
the Standard Manufacturing Company) Domestic and General Machinist, do hereby
declare the nature of my invention for IMPROVEMENTS IN DUPLEX LOCKING AND
BOLTING APPARATUS, to be as follows:-
The object of my present invention is to produce a ready and effective means of
Locking and Bolting and Fastening Doors, Shutters, Gates, Partitions, Shelves,
Ventilators, Lights, Gratings Cattle Pens and Sheepfolds, but especially applicable
to Movable Boards, in connection with Mangling, Wringing and Washing Machines;
being easily attached and locked, bolted or fastened in their respective required
positions.
I make a circular or other shaped metal casing, having a flange for the purpose
of readily attaching the same to any of the articles above mentioned; this metal
casing is spaced or recessed to afford accomodation for a cam; on one side or face
of the cam there is a round boss or projection, which passes into a hole in the
centre of the metal casing, acting as a bearing and support for one side or face of
the cam; on the other side or face of the cam there is another similar boss or
projection, which is passed into a bush or collar, thus giving a bearing or support
for the said cam, as well as to maintain the cain in its proper working position,
this bush or collar has formed upon it a projecting flange for the purpose of readily
attaching the same to any of the articles above mentioned, as in the case of the
circular or other shaped metal casing.
Having thus provided two bearings or supports, one in the metal casing and one
in the bush or collar; the cam before mentioned is free to be revolved. In this
cam I forn two curved slots or groomes, excentric with the centre of the can,
converging from the outer diameter of the cam to the centre of the boss or pro-
jection on the cam, of sufficient throw to give the desired length the bolts are
required to move; in the centre of each boss or projection on both sides or faces of
I form a key hole partly or wholly through the said bosses or projections,
in shape square or otherwise, so that a key, knob or other kind of handle, fixed or
otherwise, made the required form, shape or pattern to suit the key hole, may be
passed in for the purpose of revolving the cam; by revolving the cam with the
key, knob or fixed handle, half a revolution one way, these curved slots or grooves
in the cam recede or converge from the outer diameter, towards or from the centre
of the cam
the cam,

page_text: In each of these curved slots or grooves in the cam I place a bolt, which has
its end turned up at right angles, or a stud at its end the diameter of such
being the size of the width of the curved slot or groove of the cam: to maintain
these angle portions or studs on the end of each bolt in their respective working
positions in the cam, I form one or more slots or holes in either or any side of the
metal casing, through which the bolts have to be passed, these slots or holes in the
metal casing act as guides for the working of the bolts. Where bolts are extended
some distance from the metal casing, I place one or more sockets or guides, in
proportion to the length the bolts have to be extended.
Having described the construction and several shapes of my Duplex locking and
bolting apparatus, it will be seen that by the application of a suitable shaped key,
knob or fixed handle on either side of the cam, by half a turn or revolution, causes
the two bolts to slide, one from the opposite or any side of the metal casing.
I also arrange that either bolt can have by means of a cross piece or fork, con-
sisting of any number of ends of suitable length, which may by the half revolution
of the cam, enable the increased number of ends to be locked or bolted simul-
taneously into the same number of sockets provided for their reception.
In applying my Duplex Locking or Bolting Apparatus to the boards of Mangling,
Wringing and Washing machines, I attach the same to the centre of each board,
with the slots in the metal casing, facing the ends of the boards, the bolts which
are extended on each side of the metal casing, having their ends forked, forming a
double bolt at each end, these forked ends are passed through two guide holes,
made in a piece of angle Iron, which is fastened on each end of the board, on the
inside of each arm or bracket of the Mangling, Wringing or Washing machine,
I form a projecting ledge on which I place the boards before mentioned, on each of
these arms or brackets. I provide two holes for the forked bolts to be locked into
by the cam herein before described. I also form on the upright portion of the
frame or standard of the machine, a small projection, against which I place the
board in a vertical position, in these uprights I provide holes for the forked bolts,
the same distance apart as in the arm or bracket, enabling by the same action of
the cam as before mentioned, the boards to be locked so as to afford protection
to the rollers of the machine when not in use.
To render my Duplex Locking and Bolting Apparatus more effectual, I adopt
two means respectively first --In the length of the bolt, some distance from the
metal casing, I form a slot or recess, into which can be passed a sliding bolt or fall
latch. Secondly:-I form a recess in the outer diameter of the cam, with a slot or
groove in the metal casing in the corresponding position, adjoining this I attach an
ordinary lock or bolt to lock into the said recess formed in the cam.
The peculiar shape of the grooves of my cam render it impossible to move or
shoot the bolts either way; except by the cam being revolved with the aid of the
key, knob or fixed handle.
The great power and certainty of action contained in my cam render the
application of my Duplex Locking and Bolting Apparatus most valuable to Doors,
Gates, Lights and Ventilators which require locking or fastening, or vice versa, at
a great altitude.
I claim for it great simplicity, fewness and strength of parts, and an absence of
springs and other mechanism liable to easily get out of order.

SAMUEL HALL Strand Arcade Derby in the County of Derbyshire (Trading as
the Standard Manufacturing Company) Domestic and General Machinist do hereby
declare the nature of my invention for IMPROVEMENTS IN DUPLEX LOCKING &
BOLTING APPARATUS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of my present invention is to produce a ready and effective means of
Locking and Bolting and fastening doors, Shutters, gates, Partitions, Shelves,
Ventilators Lights, Gratings Cattle pens and Sheep-folds; but especially applicable
to movable boards in connection with Wringing and Washing machines, being
easily attached, and locked bolted or fastened in their respective required
positions.
In order that my said Invention may be more fully understood and be more
readily performed, I will explain the same with the aid of the accompanying
Drawings, which form part of this Specification, reference being made thereto by
the numerals and letters marked thereon. The same index letters refer to the
same parts, bearing the same working parts of the apparatus.

Cain.
Fig. 8 is plan of the said bush.
Fig. 9 is section of the Bush before mentioned.
Fig. 10 is a view of the -key adapted to one of my methods of locking described
in the Specification.
I make a circular or other shaped metal casing a. Fig. 1 having a flange b Fig. 1
for the purpose of readily attaching the same to any of the articles before mentioned;
this metal casing a Fig. 1 is spaced or recessed c Fig. 6, to afford accommodation for
a Cam d, Figs. 4 & 5, on one side or face of the cam d there is a round boss or
projection e Fig. 5 which passes into a hole in the centre of the metal casing f Fig. 6
acting as a bearing and support for one side or face of the cam d, on the other
side or face of the cam d there is another similar boss or projection, g Fig. 3 & 5

page_text: which is passed into a bush or collar h Fig. 7, 8 & 9, thus giving a bearing or
support for the said cam d. as well as maintaining the cam d, in its proper working
position, this bush or collar h. Fig. 7 has formed upon it a projecting flange Fig.
for the purpose of readily attaching the same to any of the articles before mentioned,
as in the case of the circular or other shaped metal casing a.
Having thus provided two bearings or supports, one in the metal casing a, and
one in the bush or collar h. the cam à before mentioned is free to be revolved. In
this cam d I form two curved slots or grooves x & x¹ Fig. 4 excentric with the
centre of the cam d converging from the outer diameter of the cam d to the centre
of the boss or projection of the cam d, of sufficient throw to give the desired length
the bolts m. Fig. 1, 2 & 3, are required to move; in the centre of each boss or
projection e & g Fig. 5; on both sides of the Cam d I form a recess n n¹ Figs. 1, 3
& 4, in which I form two holes o & o¹ Figs. 1, 3 & 4 into which I place the ends of
the key p&p¹ Fig. 10. I may also form if desired a key hole partly or wholly
through the said bosses or projections e & g Figs. 3 & 5, in shape square or otherwise,
so that a key, knob or other kind of handle fixed or otherwise, made the required
form, shape, or pattern to suit the keyhole may be passed in for the purpose of
revolving the Cam d. With the key Fig. 10 or other shaped key, knob, or fixed
handle, the Cam d is revolved half a revolution then these curved slots, or
grooves x & x in the cam d, recede or converge from the outer diameter towards
or from the centre of the cam d.
In each of these curved slots, or grooves x & x in the cam d I place a bolt,
which has its end turned up at right angles m¹. Fig. 3, or a stud at its end, the
outer diameter of such, being the size of the width of the curved slots or
grooves x & x² of the cam d. To maintain the angle portions or studs on the end of
each bolt in their respective working positions in the Cam d I form one or more
slots or holes in either or any side of the metal casing a Fig. 6 through which the
bolts m have to be passed these slots or openings & Fig. 2, & 6, in the metal
casing a Fig. 6 act as guides for the working of the bolts m. Where bolts are
extended some distance from the metal casing a I place one or more sockets or
guides in proportion to the length the bolts have to be extended.
Having described the construction and several shapes of my Duplex locking and
bolting apparatus; it will be seen that by the application of a suitable shaped
key, knob, or fixed handle on either side of the cam d & by half a turn or revo-
lution, causes the two bolts m to slide one from the opposite or any side of the
metal casing a, I also arrange that either bolt can have by means of a cross-peice
or fork consisting of any number of ends, of suitable length which may by the
half revolution of the cam d enable the increased number or ends to be locked
or bolted simultaneously, into the same number of sockets provided for their
reception.
In applying my Duplex locking and Bolting apparatus to the boards of Wringing
and Washing machines Figs. 1, 2 & 3, I attach the same to the centre or desired
position, of each board, with the slots r & 1 Fig. 2, 3 & 6 in the metal casing a
facing the ends of the boards & Fig. 1, 2 & 3, the bolts m. which are extended on
each side of the metal casing a having their ends forked, forming a double bolt, at
each end m² Fig. 1, 2 & 3 these forked ends m² Fig. 1, 2 & 3 are passed through
two guide holes made in a peice of angle iron t Fig. 1, 2 & 3 one of these said
_peices is fastened on each end of the board s Fig. 1, 2 & 3; on the inside of each
arm or bracket of the Wringing and Washing machine, I form a projecting ledge
on which I place the board before mentioned on each of these arms or brackets
I provide two holes for the forked bolts to be locked into by the can d herein
before described; I also form on the upright portion or standard of the machine, a
small projection against which I place the board in a vertical position, in these
uprights I provide holes for the forked bolts, the same distance apart as in the arm
or bracket, enabling by the same action of the cam as before described, the boards
to be lecked so as to afford protection to the rollers of the machine when not
in use.

page_text: To render my Duplex Locking & Bolting apparatus more effectual, I adopt two
means respectively first :-In the length of the bolt some distance from the metal
casing a I form a slot or recess into which can be passed a sliding bolt, or fall latch.
Secondly I form a recess in the outer diameter of the cam, with a slot or groove
in the metal casing, in the corresponding position, adjoining this I attach an
ordinary lock or bolt, to lock into the said recess formed in the cam d.
The peculiar shape of the grooves x & x¹ of my cam & render it impossible to
move or shoot the bolts m & m² either way, except by the Cam & being revolved
with the aid of the key Fig. 10 knob or fixed handle.
The great power and certainty of action contained in my Cam d render the
application of my Duplex Locking & Bolting apparatus most valuable to Doors,
Gates, Lights, & Ventilators which require locking or fastening or vise-versa at a
great altitude.
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
1st Its great simplicity & fewness and strength of parts.
2nd Absence of springs and other mechanism liable to easily get out of order;
and I claim the entirety or whole of my locking apparatus as substantially, as for
the purpose herein described and shown in the Drawings.
