Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
OSMOND, of London Street, Tottenham Court Road, in the County of Mid-
dlesex, Cabinet Maker, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of October, in the eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,.
the said George Osmond. Her especial licence, full power, sole privilege and
authority, that I, the said George Osmond, my exors, adñors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN FASTENINGS POR
DOORS, DRAWERS, WINDOW SASHES, AND DINING TABLES, AND IN APPARATUS POR
SUSPENDING LOOKING-GLASSES AND OTHER ARTICLES;" in which said Letters Patent
is contained a proviso that I, the said George Osmond, shall cause a par-
ticular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in Her said Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Osmond, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention relates,-
First, to the construction of sliding bolts, and the sockets or apparatus used
therewith, in order to render the use of sliding bolts more safe and secure.
Figure 1 shows a side view, Figure 2 a plan, and Figure 3 another side view
of a sliding bolt to be used for fastening doors and window sashes, the size of
bolt and apparatus being varied according to the object to which the same
are to be applied. a is the sliding bolt; b, the handle by which the bolt is
slided; c, the plate by which the bolt is affixed to the door. On the bolt is
affixed a neb or projection d, and it will be seen that the bolt is embraced by
three or other number of straps e, f, g, there being an opening through each
strap, so that the neb d may pass, the openings being so placed that the bolt
will not slide through the openings in each strap in succession, but the bolt
requires to be turned partly round after passing through the opening in either
strap before it can pass through the opening in the next, thus making a com-
plex movement necessary before the bolt can be withdrawn, rendering it
difficult for any person externally to move the bolt, and such person would be
prevented doing so unless complete command be obtained over the bolt. I
would remark that it is not necessary that the openings be through the straps,
as grooves may be made sufficiently deep for the passage of the neb of the bolt.
In some cases; in place of the straps being on the bolt plate, the straps are
made in the .socket into which the bolt is shot. Figure 4 shews a plan of a
bolt having a neb at the end suitable for the grooved passage formed in the
socket. Figure 5, the groove formed in the socket, is similar to the opening
in the previously described Figures, so that the bolt in being slided, the neb
moves for a short distance into the socket, then, being turned half-way round,
is again forced a short distance, and then again turned half-way round, and so
on; if desired in order to make the bolt still more secure there is applied a
stop h, which, in the passage of the neb of the bolt, is raised upwards, and
when down the bolt cannot be withdrawn till such stop is raised, by which
additional security is obtained. Figures 6, 7, 8, and 9, shew various views of
the socket and parts connected therewith separately.
I will now describe the second part of my Invention, which relates to appa-
ratus for retaining one of two folding doors when the other is shut, and this
apparatus is shewn at Figures 10, 11, 12, and 13. Figure 10 shews a front
view partly in section of this part of my Invention applied to two folding

page_text: doors. is the door which is to be fastened by the apparatus when the door
is shut, so that by locking the lock on the doorj both doors will be retained
fast. Figure 11 is a vertical section through part of the door i, shewing how
the apparatus holds that door. Figure 12 is an under side view or plan of the
apparatus; and Figure 13 is a vertical section of the part of the door j, shew-
ing how it operates on the apparatus. k is an axis turning in, bearings in the
frame, and on one end at m is formed a. projection, which is caused at all
times to have a tendency to stand upright when permitted so to do, and 'this
tendency is caused by the spring n, which at all times acts to press up the
projection m; on the other end of the axis is another projection o, which is
caused to rise up, when, by the closing of the door j, the projection-m is
depressed by the closing of the door j; and this projection o moves into a recess
formed in the under part of the door i to receive it, by which the door i cannot
be opened so long as the door j is shut, and keeps down the projection m.
I will now describe the third part of my Invention, which relates to a mode
of constructing keys for locks of doors and drawers. The lock shewn is one
having a spring sliding bolt, but the form of the bolt and apparatus consti-
tuting the lock may be varied. The key p is hollow, and has a stud.projecting
into the interior of the pipe of the key; thus the key in passing on to the pin
or axis g, enters a groove, which may be straight or incline around the axis, as
is shewn in the Drawings. Figure 14 shews a front view of a lock having
this improvement applied thereto. Figure 15 shews a section; and Figure 16
shews the key, and also the pin or axis 7 separately, and it will be seen that
the pin or axis has the projection q', in which may be formed slits and other
devices to work on wards or act on tumblers, according to the purpose to which
the lock is to be applied; in fact it will be seen that the pin or axis 9 may be
said to form a part of the key, and the part p the moveable stem or handle of
the key, because p and q together perform the office of an ordinary key.
>
I will now describe the fourth part of my Invention, which relates to fasten-
ings for dining tables. Figure 17 shews an under side view partly in section
of parts of two flaps of a dining table, having apparatus applied thereto,
according to this part of my Invention, for fastening the same. Figure 18
is a section of parts of two flaps; on one flap is affixed the part-r, through
which there is an opening to allow of the passage of the bolts, which is
moved partly round by means of the bandle t affixed thereto; when to fasten
or unfasten the two flaps the apparatus u is affixed to the other flap, as-is
shown; and on one end of the bolt sis formed a neb s', which can enter the
opening of the other part of the apparatus when the, handle is in the position
shewn by the dotted lines, but when through the moving of the handle to the

page_text: position shown in the Drawing, will cause the screw at the other end of the
bolt to screw into the nut and draw the two flaps together, the neb s¹ not being
capable of passing out of the other part of the apparatus till the handle is
again brought into the position shewn by the dotted lines.
I will now describe another arrangement of apparatus for fastening the flaps
of dining tables. Figure 19 is a longitudinal section of a dining table, and
Figure 20 is part of an under side view thereof. In this arrangement there are
plates v affixed under the table, only one of which is shown in either view, and
under the other end of the table are affixed plates w, with apparatus or bearings
for receiving screws a in such inanner that the screws can turn freely without
otherwise moving from the position shown in the Drawing. There is one of
these plates w and screws a near each side of the table, but only one is shewn
in either view of the Drawings. There is a square end formed on each of the
screws for receiving a key. y, y, are plates having fixed projections with
female screws formed through to receive the screws ; by this arrangement,
and by the connecting plates, the parts of the table are drawn tightly together,
as is shown. I have not thought it necessary to shew the means of construct-
ing the frame of the table so as to expand, that will be done by any of the
ordinary means, as is well understood.
I will now describe the fifth part of my Invention, which relates to fastenings
for window sashes. Figure 21 shews a vertical section of parts of two sashes,
having a fastening applied thereto according to this part
of my
Invention.
Figure 22 shews a plan of 'the same; and Figure 23 shews the separate parts
of this fastening. A is the upper sash, and B the lower sash. The fastening
consists of the hinged plate C, having a projection or hasp D on the under part
thereof, the hinged plate being so hinged as not to be allowed to go too far
back; the hasp or projection D passes into an opening formed in the upper part
of the other part of the apparatus, and in doing so receives the sliding bolt E,
as is shewn, by which the hinged plate C will be retained secure till the bolt E
is slided back by hand by the handle F.
I will now describe another arrange-
ment of fastening for window sashes. Figure 23* shews a vertical section of
parts of two sashes; and Figure 24 shews some of the parts separately. The
socket G, which is affixed to the upper sash, receives the head of the sliding
bolt H, and when the sliding bolt is forced into the socket the stop I is
permitted to descend, and it is caused to do so by the spring below, as is
shewn; and the coiled spring causes the bolt to be drawn on tightly, which
tends to keep the upper sash tightly to the lower sash, as well as to fasten the
two together, so long as the stop I remains down, and when that stop is raised
on its axis the bolt will be withdrawn by the coiled, or it may be other spring,

page_text: and either of the sashes may be moved. Figure 25 shews the socket separately.
Figure 26 shows a plan and section of the parts.
I will now describe another part of my Invention. Figures 27 and 28 show
two plans of part of two sashes, with apparatus applied thereto, according
to my Invention for fastening them; and Figure 29 shows the parts of the
apparatus separate from the sashes. Figure 27 shows the parts in the position
before fastening, and Figure 28 when the sashes are fastened by means of the
apparatus. J is a sliding bolt, having a neb at J'; and K is a socket through
which the front plate of the bolt can be slided when the apparatus is in
the position shewn at Figure 27, and the neb will retain the parts securely
together when the handle on the bolt is moved into the position shewn at
Figure 28, the neb being drawn tightly against the front plate of the
socket by the inclined surfaces at L; and M is a slot formed in the strap N,
which embraces the bolt, into which slot the neb enters when the bolt is drawn
back, to prevent the bolt being accidentally slided in.
I will now describe the sixth part of my Invention, which relates to appa-
ratus for suspending looking-glasses and other articles, and articles where
rollers are used, such as roller blinds. Figure 30 shows apparatus for
suspending one side of a swing looking-glass, the other side being suspended
by a similar apparatus. O is a plate, having at back a hollow cone which
receives the conical axis P with a cylindrical stem, as is shewn, on the end of
which is fixed a collar; and Q is a coiled or it may be other spring, which
tends at all times to draw the conical axis into the hollow cone, and by the two
conical surfaces being thus drawn together a quantity of friction is produced,
which will retain a swing looking-glass in the position desired. R is the plate
which, by an opening and slit, receives the end of the conical axis, and by the
nicks cut in the conical axis, the slit in the plate R will hold the axis securely;
or in some cases I dispense with the spring Q altogether, in which case the
nut a would be screwed close upon the washer b, with capability of adjustment
according to circumstances. Figure 31 shows another arrangement of appa-
ratus where a conical axis is used, the only difference in this from that before
described is, that the plate R has a dovetail projecting recess to receive the
dovetail head of the conical axis, and the screw nut is retained by a screw P'
passed through from the front of the apparatus, as shown, to keep the cones in
tight contact. Figure 32 shews another arrangement of apparatus for
suspending swing looking-glasses according to my Invention; in this case the
axis is cylindrical, and has a groove formed around it, and this grooved portion
of the axis (1) is embraced by a strap (3), the end of the strap being drawn
tight on the axis by a screw nut (4), as shewn. The plate for receiving this

page_text: axis is similar to that described at R, Figure 30; or, in place of using a strap;
a screw may be passed through the bearing, and by pressing on the axis give
the requisite friction.
I will now describe apparatus for suspending roller blinds or rollers for
suspending maps. Figure 33 shows a front view of an apparatus according
to this part of my Invention. Figure 33* shews an interior end view.
Figure 34 shews a section; and Figure 35 is an exterior end view. R is
the roller, the axis of the right-hand socket of which has a disc S affixed
thereto; this disc, at its upper part enters between curved grooves formed
in the plates T, as shewn. In the plate T is formed an oblong opening
through which the hollow tube or axis V passes, such tube or axis
baving a square hole through it to receive the square axis of the roller,
on which is fixed the disc, or the disc S may be affixed to the hollow.
tube or axis Y, with a square or other suitable shaped hole formed therein to
receive a suitable pin upon the end of the roller. U is a spring constantly
pressing up the hollow axis V, by which the disc is pressed closely into the
curved groove, and thus is friction produced, which retains the roller in any
position it may be left. The spring has an adjusting screw, as is shewn, which
adjusts the degree of pressure of the spring on the hollow axis.
Another arrangement of this part of my Invention is shewn at Figure 36
applied to a roller. Figure 37 shews separate views of the parts. (5) is a
square axis which enters a square recess formed at one end of the roller; this
square axis has formed thereon a cone (6) which enters a hollow cone (7);
which has a ratchet wheel (8) formed thereon, which is retained from turning
in one direction by the click or stop (9) moving on an axis on the plate (10);
as shewn; the plate (10) having an opening formed therethrough, as shewn.
(11) is a spring to draw the conical part of the axis into the hollow cone, there
being a screw nut on the spindle of the cone, as, shewn; by this arrangement
there will be a constant friction offered against the weight of the blind or map
drawing round the roller, the roller being in this case, as in the former
case, raised by a cord on the pulley axis. (12).
Another arrangement of apparatus for roller blinds and roller maps is shewn
at Figure 38; in this case there is a ratchet wheel (13) affixed on the square
axis, which receives one end of the blind; (14) is a click or stop, which can be
raised by means of a cord (15) acting on the lever (16), and so long as the
cord (15) is pulled the blind or map can be drawn down, but the blind will be
stopped as soon as the cord (15) is released. This roller, as in the previous
cases, is to be turned by a cord acting on a pulley axis similar to those shewn
at (12) in the former Figures.

page_text: Ilaving thus described the nature of my Invention, and the best means I am
acquainted with for performing the same, I would have it understood that I do
not confine myself to the precise details, so long as the peculiar character of
either part of my Invention be retained; but what I claim is,―
First, the improvements in sliding bolts described in respect to Figures 1, 2,
3, 4, 5, 6, 7, 8, and 9.

described in respect to Figures 17 and 18. And I also claim the mode of
constructing fastenings for dining tables, as described in respect to Figures 19
and 20.
Fifthly, I claim the mode of arranging fastenings for window sashes, as
described in respect to Figures 21, 22, and 23; and also as described in
respect to Figures 23*, 24, 25, and 26; and also as described in respect to
Figures 27, 28, and 29.
Sixthly, I claim the modes of applying conical axes and bearings for
suspending swing looking-glasses, as described in respect to Figures 30, 31,
and 32. And I also claim the modes of arranging apparatus for suspending
roller blinds and roller maps, as described in respect to Figures 33, 33*, 34,
