PROVISIONAL SPECIFICATION.
Improvements relating to Turntables for Portable Railways.
I THOMAS ROBB of No. 1 Leoville Terrace, Belmont Road, West Green,
Tottenham, in the County of Middlesex, Labour Superintendent do hereby declare
the nature of this invention to be as follows
The object of my invention is to afford an easy and reliable method of
transporting all classes of merchandise or manufactures in a safe reliable and
quick manner by means of a turntable used with light and portable railways or
tramways. The apparatus consists in itself of a set of light steel rails on which
runs a trolley of ordinary construction. For the better convenience in trans-
shipping or transporting the merchandise as placed upon the trolley, I use a
turn-table of special construction which is the subject matter of my application.
This turn-table consists of a round plate with holes at equal distances placed
around the outer edge. Into these holes the rails are fixed as required. The
turn-table revolves upon a pivot fixed in the centre of the plate and upon this turn-
table is a frame work corresponding to the rails upon which the trolley runs.
On the pivot in the centre of the turn-table is fixed a hook which catches the
axle of the trolley keeping it in its place while the table is turned and preventing
it from running over the rails too far in any direction. In order to protect the
bearings of the turn-table they are placed immediately beneath the plate forming
the top, preventing the dust or dirt from reaching them. The rails are also con-
structed with detachable fixings; a pivot dropping into a slot to complete the
fastening: the connection between turntable and rails being easily effected.
Dated this 24th day of March 1893.

COMPLETE SPECIFICATION.
Improvements relating to Turntables for Portable Railways.
1, THOMAS ROBB of 1 Leoville Terrace Belmont Road West Green Tottenham
in the County of Middlesex Labour Superintendent, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of my invention is to provide for portable railways a turntable of
improved construction. A round plate with holes at equal distances apart around
the outer edge forms the base of the turntable. The rails are fixed by stops or
staples dropped into these holes or by detachable fittings having staples which fall
into the holes as sockets. A framework revolving on a pivot and having rails of
similar gauge and pattern to the portable rails used is fitted above the plate. A
stop is fitted near the central pivot to prevent the trolley or carriage from running
over the rails. In order to raise or depress the turntable I employ a rising and
falling trestle.
The action of my improved turntable is as follows:-
When bunkering ships, for which purpose my improvements are chiefly devised,
or rapidly passing goods in trollies along a portable railway, one or more turn-
tables are fixed at intervals, each being raised or lowered by the trestle to such
CD 077

page_text: height as may be required. The trolley being passed or propelled along the rails
till it reaches the turntable is then caught by the stop and the table being turned
it is sent along another line of rails in any required direction.
In order that my invention may be better understood I append drawings in
which Fig. 1 is a general view, Fig. 2 an end elevation, and Fig. 3 a plan of the
improved turntable.
A is the bed plate with holes E, E, E. The framework is lettered B with rails
or edge at D. D. CC are fastenings as fixed. F is the stop to prevent the over-
running of the trolley, and G the adjustable trestle.
Similar letters in all the figures refer to similar parts.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A turntable with bed plate having holes at equal distances apart to fix rails at
the required angle, and turning framework.
2. A stop or projection on turntable.
3. A rising and falling trestle for turntable.
4. A turntable as described and illustrated substantially and as set forth.
