An Improved Lift or Elevator.
I, THOMAS MARKER of 34 Brecon Road Lillie Road Hammersmith London W.
Carpenter and Joiner do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved lift or elevator, mainly intended for use in
depositing goods from carts into cellars, particularly applicable to publicans in
storing barrels.
Four strong corner posts are furnished, preferably of iron, acting as guides,
between which the platform moves. From each corner of the platform, a chain or
wire passes to the top of the lift and thence over a pulley to a heavy weight at the
side. Two of these weights are preferably employed, one at each side, the
combined weights of which I propose to make greater than that of the platform and
of any articles it is likely to carry. Thus whatever is put on to be raised or
lowered, the platform will be carried to or kept at its uppermost position, and will
be lowered only by applying force. A chain or wire is connected to the underside
of the platform and passes over pulleys at the bottom of the lift to the side, where
it is wound upon a roller or wheel, furnished with a handle so that the cord can be
wound up, drawing down the platform. A ratchet wheel is provided on the winding
apparatus, and a pawl attached to a lever at the side, which when in position, retains
the mechanism and prevents the platform being raised. To this lever is also
connected a band brake passing over a brake wheel, and so arranged that when the
lever is pulled, withdrawing the pawl, the brake is put on, regulating the speed at
which the platform will rise, and stopping it when required. This lift is intended
to be used in place of the inclined plane commonly employed, up and down which
the goods are slidden or rolled. I intend to make the trap doors used with such
articles with iron frames fitted with glass, instead of the common wooden doors, and
to provide quadrant stops for holding them in open position.

An Improved Lift or Elevator.
I, THOMAS MARKER of 34 Brecon, Road Lillie Road Hammersmith London W.
Carpenter and Joiner. 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
3 and by the following statement:—
•
This invention relates to an improved lift or elevator mainly intended for use in
depositing goods from carts into cellars, particularly applicable to publicans in
storing barrels.
Four strong corner posts are furnished, preferably of iron, acting as guides,
between which the platform moves. From each corner of the platform, a chain or
wire passes to the top of the lift and thence over a pulley to a heavy weight at the
sides. Two of these weights are preferably employed, one at each side, the
combined weights of which, I propose to make greater than that of the platform
and of any articles it is likely to carry. Thus whatever is put on to be raised or

page_text: owered, the platform will be carried to or kept at its uppermost position, and will
bo lowered only by applying force. A chain or wire is connected to the underside
of the platform and passes over pulleys at the bottom of the lift to the side, where
it is wound upon a roller br wheel furnished with a handle so that the cord can be
wound up, drawing down the platform. A ratchet wheel is provided on the winding
apparatus, and a pawl attached to a lever at the side, which when in position, retains
the mechanism, aud prevents the platform being raised. To this lover is also
connected a baud brake passing over a brake wheel, and so arranged that when the
lover is pulled, withdrawing the pawl, the brake is put on, regulating the speed at
which the platform will rise, and stopping it when required. This lift is intended
to be used in place of the inclined plane commonly employed, up and down which
the goods are slidden or rolled. I intend to make the trap doors used with such
articles with iron frames fitted with glass, instead of the common wooden doors, and
to provide quadrant stops for holding them in open position.

1 :
In order that the invention may be more clearly understood reference is had to
accompanying sheet of drawings in which
Fig. 1. is a front elevation and Fig. 2. a vertical section takon at right angles to
Fig. 1. of the improved lift.
:
A is the framework formed of four posts of wood, iron, or other material and
cross pieces, having at top the trap door a through which the goods are removed
or supplied. Within this frame moves the platform B. which fit the frame closely
at the four posts which form guides for it. To each corner is fixed a chain or
rope C by any well known means. Two endless chains are employed in the
arrangement shown, one chain passing from back to front or side to side, and over
pulleys as hereinafter described.
Each chain passes from the platform over pulleys c at the top of the frame to the
weight D two of which are employed one at each side of the frame together of
greater weight than the platform and load.
.
The chain also passes from the lower part of the platform over the pulleys c²¸²³
directly or otherwise to the winding device. This device consists of an axle or
shaft E mounted in suitable bearings on the frame and furnished with grooved
julley wheels F on which the chains are wound, one wheel being used for each
thain.
A: handle e is fitted to the end of the shaft and a ratchet wheel'e' and brake
wheel are also provided. A spring pawle is provided at the sides of the ratchet
wheel and prevents the shaft turning except in one direction, when it is in place.
A handle is pivoted to the frame at the side to which is connected a band brake g
which encircles the wheel e when the lever is pulled back, thus putting tho brako
in when desired. The same notion which puts on the brake releases the
pawl by means of a pin or like device on the handle pushing down the end
of the pawl.
As shown more clearly in Fig. 2. the chain C. passes from the side of the platform
opposite the winding device, over the pulleys a at the bottom of the frame, to the
winding wheel F over it to the bottom pulley & thence to the weight D from which
it passes over the pulley, c to the platform at the side of the winding wheel. From
the bottom of the platform it then passes over the pulleys to the other weight D
over the pulley c. and back to the platform at the side from which it started. It is
obvious that the chain may be made discontinuous if desired but the arrangement
shown is considered must convenient. To lower the platform, the chains Care
"wound-over the wheels F & more in the direction indicated by the arrows, so that
tho weights are raised at the same time.
:
...llaving 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 lift or elevator of the kind described consisting of a frame, a platform within
` the sniði frame connected by 'chains to-balance-weights-heavior that the platform

specified.
2. In a lift or elevator of the kind described in Claim 1. a controlling device on
the end of the winding shaft consisting of a ratchet wheel and spring pawl, operated
by a lever which can raise the.pawl out of action, and a brake wheel and band brako:
connected to the said lover in such a manner that when the pawl is removed, the-
saino action of the lever puts on the brake and vice versa, substantially as described
and shown and for the purposes specified.
3. The improved lift or elevator constructed and operating substantially in the-
manner described and illustrated in the accompanying drawings and for the purposes-
specified.
