page_text: LETTERS PATENT to James Archer and Thomas Lambley Archer, both of
Number 18, Fennel Street, Manchester, in the county of Lancaster, for an
invention of "IMPROVEMENTS IN THE MEANS OR CONTRIVANCES USED FOR
HOLDING SECURELY IN PLACE THE GLOBES OR GLASSES OF GAS AND OTHER
PROVISIONAL SPECIFICATION left by the said James Archer and Thomas
Lambley Archer at the Office of the Commissioners of Patents on the
11th May 1882.
JAMES ARCHER and THOMAS LAMBLEY ARCHER both of Number 18 Fennel
Street, Manchester, in the County of Lancaster, IMPROVEMENTS IN THE MEANS OR
CONTRIVANCES USED FOR HOLDING SECURELY IN PLACE, THE GLOBES OR GLASSES
OF GAS AND OTHER LAMPS
Our Invention consists substantially, in substituting the following simple and
secure arrangement of apparatus in lieu of the thumb screws and other contrivances
hitherto employed for accomplishing the like object:-That is to say, for the
purpose of securing, according to our Invention, the ordinary globes for gas burners
(the said globes having a flange or projecting lateral ridge at the base thereof)
We form in one of the arms or members of the globe holder a slot into which takes
a sliding clamp piece with a spring attached to a small stop or catch piece,
underneath the said clamp piece-in such manner, that in order to allow of the
removal of the globe, it is only necessary to pull the said stop or catch piece, when
the spring is extended; and, vice versa, to secure the globe in position, in the
holder, the spring is compressed on releasing the same.
In adapting our said Invention to the holders of what are known in the Trade
as the "Comet" globes (the said globes not having any lateral projecting ridge as
in ordinary globes) We adapt to the spring before mentioned, a pivotted operating
lever, the end of the same which secures or clips the globe, being,-with a view to
prevent the possibility of damage to the glass,-padded with india-rubber or other
suitable resilient material.

CONTRIVANCES USED FOR HOLDING SECURELY IN PLACE THE GLOBES OR GLASSES
OF GAS AND OTHER LAMPS
"
Our Invention consists substantially in substituting the following simple and
secure arrangements of apparatus in liew of the thumb screws and other
contrivances hitherto employed for accomplishing the like object. That is to say
according to our Invention for securing the ordinary globes for gas burners (the
said globes having a flange or projecting lateral ridge or rim at the base thereof)
we form, in reference to Figures 1 and 2,-in one of the arms or members B of
the globe holder A, a slot, into which takes a sliding clamp piece C with a spring c
attached to a small stop or catch piece c underneath the said clamp piece in such
a manner that in order to allow of the removal of the globe it is only necessary
to pull the said stop or catch piece, when the spring becomes extended; and
vice versa, to secure the globe in position in the holder, the spring is compressed
on releasing the same.
In adapting our Invention to the holders or "galleries" of what are technically
known as the "comet" globes (such globes not having any projecting lateral ridge
or rim as in ordinary globes) one or other of the following arrangements; that is
to say according that illustrated in Figure 3. the spring is adapted to a lever c¹
pivotted at d, the end whereof secures or clips the globe as shewn; the releasing
of the same being accomplished by the extension of the spring. The position of
the fingers of the operator being shewn in the Figure: We prefer also with a view
to prevent the possibility of damage to the glass to pad or protect the end d¹ with
india rubber or other suitable resilient material.-Under another arrangement,
shewn in Figure 4, for this class of "galleries" or holders, the spring gripping and
releasing is accomplished by means of a small eccentric A slotted as shewn at C
and working on a pivot at B. Working in the slot C is a small pin D fixed to
the member E working on on a center F. The eccentric A has an elongated
stem A¹ serving as a handle, and to which also is connected as shewn, the spiral
spring c. The modus operandi is substantially the same as that as described
for the proceding modification, and will be self-evident on referring to the
illustration,
Having now described and illustrated our said Invention we wish it to be
understood that we do not make any claim as to novelty in regard to the pivotted
lever c¹ of Figure 3, by itself. But what we do claim is First:-The arrangement
substantially as described and shewn in reference to Figures 1 and 2 for the one
class of globe holders: Second-The arrangement substantially as described and
shewn in reference to Figure 3 in so far as regardes the application and combination
of the spring c¹¹and Third the arrangement generally and substantially as
shewn and described in reference to Figure 4. In witness whereof we the said
James Archer and Thomas Lambley Archer have hereunto set our hands and
seals this eighth day of November in the year of Our Lord One Thousand Eight
Hundred and Eighty two.
