Portable Lift or Loading Platform..
WILLIAM THOMAS ROUNSIVELL, Mechanical Engineer, of 121 & 123, Union
Street, Borough, London, S.E., do hereby declare the nature of this invention
to be as follows:.
The object of my invention is to provide an arrangement for dealing with
goods where the usual jib crane cannot be fixed, and for raising or lowering
goods inside a warehouse or the like or for transporting goods from one position
to another upon the same hïung mechanism. The invention consists of another
arrangement of my Patent No. 23561/98 but I dispense with the four vertical
screws in the corner posts and hit the platform by means of a suitable winding
gear consisting of a shaft, either geared up or not as may be necessary, on which
is fixed two barrels one on either end. From these barrels four wire ropes are
conducted in the following manner. Two of the ropes lift direct from the barrels
to the platform, the other two pass down the sides of corner posts under sheaves,
across the lower frame work under two other sheaves, up to the top of the posts
over two more sheaves, and down to the platform. A chain or the like can be
substituted for the wire ropes. In short I perform the lifting of the platform
by means of drums, shafts, pinion and wire ropes in place of the vertical screws
in my Patent No. 23561/98.
I also provide a method for propelling the entire machine by means of spur
wheel, pinion, shafts and handles geared with the wheels on which the plat-
form rests.

and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-

page_text: screws in the corner posts. Referring to the accompanying drawing, a, is a
framing of iron or wood mounted on wheels, 61, 3, which are carried on fixed
brackets. ¹, ², are two similar wheels mounted on swivel brackets d¹, d².
In order to increase the portability of the machine I fix two other rollers K¹, K²,
in centre of framing. Uprights e¹, e², e³, e, are fixed at each corner. They
are of suitable shape to receive the platform or table f which is made to move
freely vertically between the corner posts. At the top of posts at one end are
two pulleys g, 9. At the top of the other two posts are two drums h¹, h³.
At the bottom of the framing at each corner are four sheaves J, J, J³, J.
Wire ropes or chains are used for lifting the table f in the following manner.
Starting at the drum h³, one passes down around sheave J, Fig. 2, along hori-
zontally to sheave J³, Fig. 2, up and over sheave g³ down to platform where
it is fixed. Another rope or chain passes in the same manner starting from
the drum h¹ Fig. 2, around sheaves J, J2, g¹, Fig. 2 to platform. These two
ropes or chains lift one end. For lifting the other end, two ropes or chains
pass direct from drums and h³, down to the platform.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1 The application and combination of parts as herein described and illus-
trated.
2 The same combination of parts embodying the same idea as herein and
before described but designed to meet the various commercial requirements.
