PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Despatch Carriers.
We, LAMSON PNEUMATIC TUBE COMPANY, LIMITED, and ROBERT THOMAS
JENNEY, Engineer, both of 20, Cheapside, in the City of London, do hereby
declare the nature of this invention to be as follows:-
According to this invention it is proposed that the carrier should be composed
of an inner shell made of a tube closed at one end with the requisite segment
of tube between the closed and open end removed. Just inside the open end is
a circumferential ledge or groove adapted to engage with a projecting piece or
finger upon a separate end piece such piece being secured to the closed end of
the outer tube by screws bolts or the like, the two shells being thus secured
together but capable of partial rotation one within the other, a stop being provided
to limit their respective movements in either direction.
The outer shell has as stated one open and one closed end and the requisite
Felt caps
segment of tube between such ends is removed as with the inner shell.
or other packing is secured to the closed ends of the respective tubes.
Dated this 14th day of June 1899.

For the Applicants,
We, LAMSON PNEUMATIC TUBE COMPANY LIMITED, and ROBERT THOMAS
JENNEY, Engineer, both of 20, Cheapside, in the City of London, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to the carriers such as are used in the pneumatic systems
employed in shops and other places, for the carriage of money bills and other
small articles from one station to another.
In order that the invention may be clearly understood reference is made to
the accompanying drawing in which Fig. 1 is a sectional elevation of a carrier
when open made in accordance with this invention: Fig. 2 is a plan view taken
on the liner: Fig. 3 is a sectional elevation when the carrier is closed, and
Fig. is a plan view on line y y
According to this invention it is proposed that the carrier should be composed
of an inner shell A made of a tube closed at one end B with the requisite

page_text: segment C C of tube between the closed and open end removed. Just inside the
open end and secured thereto or formed in one with same is a circumferential
ledge D (or it may be a groove) adapted to engage under a projecting piece or
finger E upon a separate end piece F such piece being secured to the closed end G
of the outer tube H by screws, bolts or the like, the two shells being thus secured
together but capable of partial rotation one within the other, a stop I being
provided to limit their respective movements in either direction and prevent the
shells becoming disengaged.
The outer shell H has as before stated a closed end G and the requisite segment
of tube between such end and the open end is removed as with the inner shell.
Felt caps K or other packing is secured to the closed ends of the respective
tubes.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. The improved pneumatic despatch carrier formed from separate pieces of
tubing from which suitable segments have been removed, the shells being secured
to each other by means of a projecting piece or finger secured upon one shell
engaging with a ledge or recess upon the other shell substantially as described.
2. The improved pneumatic despatch carrier formed from separate pieces of
tubing from which suitable segments have been removed, the shells being secured
to each other by means of a projecting piece or finger secured upon one shell
engaging with a ledge or recess upon the other shell, and a stop adapted to limit
the movements of the shells with respect to each other substantially as described.
3. The improved pneumatic despatch carrier formed from separate pieces of
tubing each of which is closed at one end and open at the other, means for holding
the two shells in operative position and felt or other capping material secured
to the closed ends of the respective tubes substantially as set forth.
Dated the 23rd day of February 1900.
