Year: 1881

page_text: LETTERS PATENT to George Asher, of Birmingham, in the County of Warwick,
Designer and Pattern Maker, for an Invention of "AN IMPROVEMENT RELATING
TO PERAMBULATORS AND SIMILAR VEHICLES, APPLICABLE ALSO TO OTHER
Useful PURPOSES."
PROVISIONAL SPECIFICATION left by the said George Asher at the Office
of the Commissioners of Patents on the 14th September 1881.
GEORGE ASHER, of Birmingham, in the County of Warwick, Designer and
Pattern Maker. "AN IMPROVEMENT RELATING TO PERAMBULATORS AND SIMILAR
VEHICLES, APPLICABLE ALSO TO OTHER USEFUL PURPOSES."
The object of this Invention, which has reference to an improvement relating
or applicable to perambulators and other similar vehicles, and which is also
applicable to other useful purposes, such as to music-stools, tables, and other
articles of utility, is to provide a self-acting means of securing the body of the
perambulator, the seat of the stool, or the top of the table in any desired position
to which it may be turned.
In carrying my Invention into practical effect I secure an annular flanged
guiding plate to the frame of the perambulator, or to the support of the stool, or of
the table. The flange of this ring is raised and is recessed at intervals for the
purposes respectively hereinafter referred to, and to the bottom of the body of the
perambulator, or of the seat of the stool or top of the table, I secure another
annular flanged guiding plate, the flange of this guiding plate engaging under that
of the first mentioned guiding plate. The second mentioned guiding plate is
recessed at a part and carries a radial bolt, which is pressed towards the first
mentioned guiding plate by a spring within the recess. The guiding plates which
are connected to the separate parts of the perambulator, stool, or table, and which
engage with each other, thus keep these parts in connection and in their proper
relative positions, and allow of them being turned about the common centre of the
said guiding rings to the right or left as required. The utility of the provision of
the spring bolt in the one guiding plate, with the circumferential recesses in the
other guiding plate is, that the former, on coming opposite any of the latter, springs
into engagement therewith, and keeps the parts in the arrested position until a
greater turning pressure is brought to bear upon the part being turned, when the
bevilled edges of the locking recesses force back the bolt and allow of the part being
turned into any other desired position, in which it is again similarly and auto-
matically secured.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Asher in the Great Seal Patent Office on the 14th March
1882.
GEORGE ASHER, of Birmingham, in the County of Warwick, Designer and
Pattern Maker. "AN IMPROVEMENT RELATING TO PERAMBULATORS AND SIMILAR
VEHICLES, APPLICABLE ALSO TO OTHER USEFUL PURPOSES."
I will premise the description of my Invention by remarking that since the filing
of my Provisional Specification I have discovered that the description therein con-
tained is too comprehensive and embraces various features to which I do not desire
to lay any claim under my present Letters Patent. I have therefore restricted the
following description of my Invention to those features which I believe to be
original, and which I claim as constituting my present improvements, and have
eliminated those parts of my Provisional Specification which are descriptive of
various features therein described as improvements, but which I have since found
are not as novel or of such utility as I then thought, and in respect of which I
desire it should be understood that I lay no claim.
My Invention, which has reference to an improvement relating or applicable to
perambulators and other similar vehicles, is to provide a self acting means of
securing the body of the perambulator in any desired angular position in relation
to the frame or support thereof to which it may be turned.
The accompanying Drawings illustrate the method of carrying my Invention
into practical effect, and they are marked with reference numerals which correspond
with those in the following explanatory description thereof.
1 represents an annular plate which has a guiding flange 2, and is screwed by
screws 3 or by bolts or otherwise to the frame of the perambulator. The flange 2
is raised, as best shown in the cross section, Fig. 1, and it is recessed, as at 10,
with any required number of recesses at intervals, as best shewn in the plan view
(Fig. 2) for the purposes respectively hereinafter referred to.
4 represents another annular plate, which has also a guiding flange 5, and is
secured by screws bolts 6 or otherwise to the bottom of the body of the perambu-
lator. The plates 1 and 4 are so connected as that the flange 5 of the latter engages
under the flange 2 of the former, as best shown in Figure 1.
The plate 4 is recessed or equivalently formed at 7 for the reception of a radial
bolt 8 and a coiled or other spring 9 which constantly presses the bolt 8 towards and
against the flange 2 of the plate 1.
The guiding plates 1 and 4 being, as herein before described, connected to the
separate parts of the perambulator, and engaging with each other (as illustrated on
the accompanying Drawings) thus keep these parts in their proper relative
positions, and allow of them being turned about the common centre of the said
plates to the right or left as desired.
The utility of the provision of the spring bolt (which may be otherwise formed
and fitted than as hereinbefore described without departing from the principle of
this Invention) in the one guiding plate, in combination with the circumferential
recesses in the other guiding plate, is, that the former on coming opposite any of
the latter springs into engagement therewith, and keeps the parts in the arrested
position until a sufficiently greater turning pressure is brought to bear upon the
part being turned as will cause the bevilled edges (which are best shewn in the
under plan view, Fig. 3, of the plate 1 of the locking recesses 10 to force back the
bolt 8 and allow of the parts being turned into any other desired relative position,
in which they are again similarly and automatically secured.
Having now described the nature and object of my said Invention, together

page_text: with the manner in which the same is to be or may be performed or carried into
practical effect, I would remark in conclusion that what I consider to be novel and
original, and therefore claim as constituting the Invention secured to me by the
herein before in part recited Letters Patent is,―
The combination with the body and framework of perambulators and other
similar vehicles, of annular flanged guiding plates, which are provided the one
with a series of circumferential locking recesses, and the other with a locking
spring bolt, and which are so secured to the parts as to keep them in connection,
and as to allow of them being freely turned into any required relative positions,
and automatically locked therein, with a facility of being freely turned into any
other required position and automatically locked therein, substantially as herein-
before described and as illustrated on the accompanying Drawings.
In witness whereof, I, the said George Asher, have hereunto set my hand
and seal, this Eleventh day of February, in the year of our Lord One
thousand eight hundred and eighty two.
GEORGE ASHER. (L.S.)
