Improvements in Indicating Bolts or Fasteners.
1, GEORGE FREDERICK NEWMAN of the Firin of William Newman and Sons, of
Hospital Street, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to appliances commonly called indicating bolts, and is
adapted for indicating when a place is occupied or vacant, or a person is engaged or
disengaged, or in or out, as the case may be.
The said appliance is automatically worked, by the reciprocation of the shoot of a
bolt or other fastener.
The object of my invention is to simplify the construction, and to render more simple
and efficient, the said indicating bolts or fasteners.
My invention consists essentially, in carrying the words "vacant," "occupied" or
the like, indicative that a place is vacant or engaged, or a person in or out, upon a
barrel having an helical slot at its back, and operated by a pin or stud, on the shoot
of the operating bolt, reciprocating within a longitudinal slot of an attachment plate,
and taking within the said helical slot of the barrel.
In carrying out my invention, in connection with a bolt which is situated upon the
inside of a door, I provide the same with an attachment plate, and casing; and within
which said casing, which has closed ends alike unto a box, with a longitudinal slot,
directed nearly from end to end at its back a barrel with an helical groove at its back
is enclosed, and partially rotates by a stud or pin, on the shoot of the bolt taking in
the said helical slot, and reciprocating within the longitudinal slot, which is a guide
one, as aforesaid.
"
"
The front of the casing is open, or pierced with a longitudinal slot, from end to end,
or nearly so, of it, whilst the front of the barrel, has upon it, or carries, the words
occupied" and "vacant," which words are disposed in parallel directions, and one
under the other, so that the partial rotation of the said barrel, by the shooting or
withdrawal of the bolt, causes one of the said words to be presented before the
opening. Thus, the shooting of the bolt, within its staple, causes the stud carried by
it, to slide within the longitudinal slot, and operate upon the helix of the barrel, so
as to give it, the said barrel, a partial rotation, which brings the word "occupied "
before the opening, wherethrough the same is seen.
"
The reverse action of the bolt, acts in a like manner as before, and gives the barrel
a partial rotation in the reverse direction, so as to now bring the word "vacant'
before the opening.
The barrel may work upon end pivots or bearings, so as to reduce friction in the
working of it.
Instead of employing a barrel, upon which the indicative letters are carried, I may
employ a plate, with an inclined slot cut within it, so that the movement of the pin
with the shoot of the bolt, canses the said plate to reciprocate, and so bring different
words before the opening in the front of the casing.
The barrel may be made or provided with, facets upon its front side, upon which
the lettering or words, as aforesaid, come.
The barrel may if necessary be made to carry only a portion of a word, such as
dis," of the word "disengaged," of which the latter part, "engaged "always remains
stationary, so that by adding to it, the letters "dis," or taking the said "dis" away,
"engaged" and "disengaged" is thereby indicated.

Improvements in Indicating Bolts or Fasteners.
I, GEORGE FREDERICK NEWMAN of the Firm of William Newman and Sons, of
Hospital Street, in the City of Birmingham, Manufacturer do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This invention has reference to appliances called indicating bolts, adapted for
indicating when a place is engaged, or vacant, or a person is engaged or disengaged,
or in or out, as the case may be.
The said appliance is automatically operated, by the reciprocation, of the shoot of a
bolt, or other fastener.
The object of my invention is, to simplify the construction of, and to render more
simple and efficient when in use, the said indicating bolts, or fasteners.
My invention consists essentially, in carrying the words "engaged," or
1 vacant,"
or the like, indicative that a place is engaged or vacant, or a person is in or out, upon
a barrel, having a helix, or a helical slot at its back, and operated by a pin or stud,
carried by the shoot of the operating bolt.
In carrying out my invention in connection with a bolt, I provide the same with
an attachment plate or casing, with a longitudinal slot cut within it, and wherein a
barrel, with an helical groove at its back, is enclosed, and partially rotates, by a stalk
or pin, of the shoot of the bolt, taking into the said helical slot.
The front of the casing is open, or pierced with a longitudinal slot, or the said
longitudinal slot may be in a separate plate, or the one carrying the bolt, whilst the
front of the barrel, has upon it, or carries, the words "engaged," and "vacant,"
disposed in parallel directions, and one under the other, so that the partial rotation of
the said barrel, by the shooting or withdrawal of the bolt, causes one of the said words
to be presented to, or come before, the opening.
The barrel may be mounted upon end pivots, or bearings, instead of runners
simply within the casing.
Instead of employing a barrel, upon which the indicative letters are carried, I
may use a plate with an inclined channel or rib, cut in or formed within, or upon
it, so that the movement of the stalk of the shoot of the holt, causes the said plate
to rise and fall, and thereby bring different words before the opening of the
casing.
"
The barrel may be made, or provided with facets, upon its front side, upon
which the lettering or words as aforesaid, come.
The barrel may if necessary, be made to carry only a portion of a word, such as
dis," of the word "disengaged," of which the latter part," engaged" always remains
stationary, so that by adding to it, the letters "dis," or taking the said "dis" away,
"engaged," and "disengaged," is thereby indicated.
Figure 1 of the accompanying drawings, represents in elevation, the bolt side of an
indicating bolt, or fastener constructed according to my invention.
Figure 2 represents a complete horizontal section of Figure 1, upon the dotted
lines A B. This view represents a section of the door, and jamb or upright, and
also a section of the indicating part of the bolt, and the shoot and operating stalk of
the bolt in elevation.
Figure 3 represents a front elevation of the indicating bolt or fastener, with the
word VACANT, presented to the slit or aperture, directed along its front.
The parts in Figures 1 and 2, are in the positions which they assume when
VACANT is presented.
Figure 4 represents a part vertical section of the back of the bolt portion of the
indicating bolt, showing the back of the barrel, the helical slot within it, and a
cross section of the stem or stalk, which takes into the slot, and by its horizontal
movement the barrel is partially rotated.
The positions of the parts are such, as when the word ENGAGED is presented.

page_text: his, the barrel, and ², the rib, and it will be understood, that the inner end of
the stem or stalk c², as in the preceding figures, which is carried by the shoot. is
forked, and takes upon the rib, so that the moving of the said stem or stalk in a right
line over the helix, gives a partial rotatory motion to the barrel.
Figure 14 represents another form of my invention.
Figure 15 is a back elevation of the same.
In this arrangement, the words ENGAGED and VACANT, are carried by a
plate, which is caused to rise, and allowed to fall, through the agency of an inclined
groove, channel, or rib at its back.
g is an enclosing casing, wherein a plate h, with an inclined slot 2, at its back rises
and falls.
a is a bolt plate, and a³ a longitudinal groove made through it, wherethrough the
stalk c², of the head c, of the shoot d, takes, and with its inner end. engaging within
the inclined slot as aforesaid, so that by moving the shoot backwards and forwards, in
bolting and unbolting, the plate is raised and lowered within the enclosing casing, and
the words ENGAGED or DISENGAGED, brought before the longitudinal gap g*,
according to the position of the said shoot.
Thus, the shooting of the bolt into its staple plate, brings ENGAGED into position,
and the rearward action of the same, presents the word VACANT.
If necessary, the shot plate a, with its slot a², may be dispensed with, and the word
carrying plate, made to slide within vertical guides.
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 :-
First: An indicating bolt or fastener, operating the name carrier, barrel, or plate,
upon which the names to be transposed are inscribed, by an helix, or an helical slot,
through the instrumentality of a stem, or stalk, carried by the shoot of a bolt or
fastener as described and set forth.
Secondly-An indicating bolt or fastener, the combination with a name carrying
barrel, with an helical slot, or an helix at its back, of a stalk or stem, and shoot, with
a longitudinal gapped plate, wherethrough the stalk or stem, works, substantially as
set forth.
Thirdly The improvements in the construction and arrangement of the parts of
indicating bolts or fasteners, as herein described and set forth, in Figures 1, 2, 3, 4,
5. 6, 7, 8, 11, 12, and 13, whereby VACANT, ENGAGED, or like words, indicative
of a place being vacant or engaged, are presented to the gapped part of an enclosing
casing.
Fourthly-The improvements in the construction and arrangement of the parts of
indicating holts or fasteners, as described and set forth in Figures 9 and 10.
:-
Fitthly A plate indicating bolt or fastener, raising and lowering, or bringing
into alternate positions, the words ENGAGED or VACANT (or the like words) by
an inclined plane or slot, wherein or wherewith a stem or stalk, carried by the shoot
of the bolt or fastener, engages, substantially as described and set forth in Figures 13,
14, and 15.
Dated this 25th day of August 1890.
