Year: 1883

page_text: LETTERS PATENT to Hermann Hoheisen, of Pforzheim in the Empire of
Germany for an Invention of AN IMPROVED COMBINED LOCKET AND TELESCOPE
PROVISIONAL SPECIFICATION left by the said Hermann Hoheisen at the
Office of the Commissioners of Patents on the 13th October 1883.
HERMANN HOHEISEN, of Pforzheim in the Empire of Germany,
COMBINED LOCKET AND TELESCOPE
"
"AN IMPROVED
This Invention relates to a combined telescope and locket or pendant for personal
wear and consists in such a construction that the telescope when shut up may be
contained in a locket or pendant of ordinary dimensions, whilst capable of being
drawn out or extended for use to the required extent.
The locket is constructed of a short cylindrical case or band provided with a bow
for attachment to a watch or other chain, and having a hinged cover at either side.
Within this cylinder or case is fitted the telescope tube constructed of a sufficient
these
number of short sections, each of about the length of the outer band or case,
sections sliding telescopically within one another, the motion of the sections being
limited by a stud projecting from each section sliding in a longitudinal slot in the
next larger section, these slots being alternately at opposite sides of the sections.
The first or largest section is fitted in the band or case of the locket by a similar
stud engaged in a bayonet slot made in said band or case. An eye-glass is carried
by the smallest section and an object glass is fixed in the band or case of the
locket and when the telescope is collapsed these lenses are both enclosed by the
hinged covers before mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Hermann Hoheisen in the Patent Office on the 12th April 1884.
HERMANN HOHEISEN, of Pforzheim in the Empire of Germany,
COMBINED LOCKET AND TELESCOPE

"AN IMPROVED
This Invention relates to a combined telescope and locket or pendant for personal
wear and consists in such a construction that the telescope is capable of being

page_text: drawn out or extended for use to the required extent and yet when shut up may
be contained in a locket or pendant of ordinary dimensions.
In order that the invention may be more readily understood I have illustrated
it in the annexed drawings and will proceed to describe it with reference thereto
Figure 1 is a face view and figure 2 an edge view of the locket closed. Figure 3 is
an edge view of the locket with the covers thrown back previous to drawing out
the telescope. Figure 4 represents the telescope as drawn out for use (partly in
section or broken away to show the construction) the object glass being also
removed to show the mode of securing the telescope to the case and shown
separately.
The locket is constructed of a short cylindrical case or band a provided with a
bow b for attachment to a watch or other chain, and having a hinged cover c c¹nt
-either side. Within this cylinder or case a is fitted the telescope tube constructed
of a sufficient number of short sections d d' d' d³ d' &e of equal length and rather
Jess than that of the cuter band or case a; these sections slide telescopically within
ore another and the'r motion is limited by a stud e projecting from each section
sliding in a longitudinal slot ƒ in the next larger section, these slots being alternately
at opposite sides of the sections, that is to say the slots in the sections d d' d' &
are at one side and those in sections d¹ d³ d³ & are at the opposite side the
studs e being correspondingly situated. The first or largest section d is fitted in
the band or case a of the locket by a similar stud g engaged in a bayonet slot h
made in said band or case. An eyeglass i is carried by the smallest section which
as provided with a flange k to enable it to be readily drawn out, and an object
glass is fixed in the band or case of the locket and when the telescope is
ccllapsed these lenses are both enclosed by the hinged covers c c before mentioned.
The case is constructed of an external band a of channelled section or having
inwardly turned flanges, and of a straight cylindrical lining a¹ fitting within and
soldered to the said flanges. It is in this lining a¹ that the slot is made and the
first section d fits accurately ti erein. The object glass is fixed in a rim or bezel
which also fits tightly in the lining a¹ of the case.
"
The various sections d d¹ d² & are made of lengths of thin solid drawn brass
tube of suitable diameter to fit accurately upon one another and are made to slide
with the necessary stiffness by having their edges which are directed towards the
smaller end of the telescope slightly burred down or turned inwards. The slots f
do not extend quite the full length of the sections and the studs e do not project
beyond the outer surface of the section in which they work so as not to interfere
with the sliding motion of the next larger sections.
Having described the nature of the said Invention, and the manner of
performing the same, I declare that what I claim as the Invention to be protected
by the herein before in part recited Letters Patent is :-
A combined locket and telescope constructed substantially as herein shown and
described.
In witness whereof I the said Hermann Hoheisen have hereunto set my hand
and seal this 8th day of April A.D. 1884.
