COMPLETE SPECIFICATION.
Improved Lift.
J, ALOIS RENNER, Fitters Foreman, of 14 Adelgundenstr. Munich in the
Kingdom of Bavaria, German Empire, do hereby declare the nature of my
invention and in what manner the same is performed to be particularly described
and ascertained in and by the following statement :-
The present invention relates to lifts for raising food in restaurants, documents
or goods in business houses and the like and the invention consists in the construc-
tion of a wrought iron lift in such manner that the same may be fitted up ready for
fixing, at the manufactory, and only requires to be fixed in position in the house for
which it is required.
And in order to make the present invention more easily intelligible reference is
had to the accompanying drawing in which similar letters denote similar parts
throughout the several views:―
Fig. 1 being a front elevation of a lift constructed according to my invention,
Fig. 2 a side elevation,
Fig. 3 a plan and
Fig. 4 a detail view showing the mechanism for arresting the lift in its upper or
lower position.
The lift frame consists of the four angle irons a, which are connected up by
means of cross bars b, said frame having at each of two opposite sides U-shaped
guide bars cc (Fig. 3) to guide the lift d which is provided with suitable guiding
ribs to engage in said U-irons. The lift d is as usual carried on ropes or wires f
passing over the upper and lower rolls ee and having at the opposite side a counter-
balance weight g which latter is guided in U-irons arranged outside of the frame as
shown at Figs. 1 and 3 and running vertically the whole length of the same. The
lift d is arrested in its uppermost and lowermost positions by means of spring
bolts h h, as shown in detail at Fig. 4. These bolts have their ends so formed as
to be pushed back by the lift d as it passes them, but the springs of the said bolts
will actuate them outwards as soon as the lift has passed them and retained the
said lift in the position beyond them. The bolts hinay be withdrawn to allow
the passage of the lift by means of the angle levers k k connected up by a vertical
connecting rod i, which may be actuated by a pivoted lever j from any part of the
lift. The said bolts are advantageously adapted to grip under or over the guide
rib of the lift d and thus to retain the sanie in its upper and lower positions until
withdrawn.
Instead of a counterbalance weight g it is obvious that I can arrange a second
lift d to act as counterbalance weight, without departing from the principle of my
invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is
A lift which may be ready made and easily fixed in the house as desired, or
removed from the same and re-fixed in other places, consisting of the wrought iron
frame a b, having a vertical moveable box or basket d carried on a rope or wire
guided over suitable pulleys and having counterbalance weight, and guide bars, and
horizontally or approximately horizontally moveable bolts at the top and bottom,
said bolts being spring actuated and being capable of movement against their

page_text: springs by means of a connecting rod i and suitable lever to operate said rod, the
said bolt being arranged in such position relatively to the box or basket as to
grip under the same to retain it in its end positions substantially as described and
shown.
