IMPROVEMENTS IN TIP-WAGONS, AND GENERALLY APPLICABLE TO MECHANISM FOR TIPPING RECEPTACLES
Year: 1884

page_text: I PAUL DIETRICH of N° 3, Nord-Ufer, Berlin, Manufacturer, do hereby declare
the nature of said Invention for "IMPROVEMENTS IN TIP-WAGONS, AND GENERALLY
APPLICABLE TO MECHANISM FOR TIPPING RECEPTACLES," to be as follows:-
This invention relates to tilting or cradle mechanism applicable to dumping-
wagons, measuring machines and other appliances having receptacles intended to
be tilted.
The tilting mechanism chiefly comprises two pairs of arms, arranged on both
sides of the receptacle to be tilted and serving to hold the same in pivotal bearings.
The arms of each pair cross each other and are pivoted at the upper end to the
receptacle to be tilted and at the lower end to the frame of the wagon or machine,
in such manner that the left pivot of the frame is connected with the right pivot
of the receptacle and vice versa.
The two arms are connected by means of a pin passing through the same at the
point where they cross each other.
For tilting the receptacle, the pin connecting the arms is removed and the
receptacle pushed side ways, whereby the receptacle is tilted without requiring any
effort for lifting the load contained in the same.
Dated this 23rd day of February 1884.

I, PAUL DIETRICH, of 3, Nord-Ufer, Berlin, Manufacturer, do hereby declare the
nature of said Invention for "IMPROVEMENTS IN TIP-WAGONS, AND GENERALLY
APPLICABLE TO MECHANISM FOR TIPPING RECEPTACLES," and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:―
My invention relates to tipping or dumping mechanism for carts, weighing
apparatus and other appliances.
In the acompanying drawings Fig. I is an end elevation and Fig. II a side
elevation, while Fig. III illustrates a modification, and Fig. I a detail.
The object of my invention is to turn the receptacle through a greater angle than
may be obtained with ordinary tipping mechanisin, to obtain a uniform and flat
tilting action and to take up the longitudinal and lateral vibrations in a suitable
manner. The usual tipping mechanisms permit the turning of the receptacle
through an angle of 60° only. This tilting angle is frequently not sufficient for
completely emptying receptacles without movable side wall.
To adapt the tilting mechanism for completely emptying the receptacle, I inay
employ a pair of symmetrically curved levers A, B (Fig. I) which permit a tilting
angle up to 140°. To render the tilting action uniform and gradual, I employ two
pairs of U shaped levers A C A and B C B (preferably composed of tubes) which
are pivoted at their lower extremities in bearings g g fixed to the frame of the carriage.
The pivoted U shaped lever A C A takes up vibrations caused by the motion of
the vehicle and prevents breakages of the short journals which hitherto have
frequently occured.
A further improvement consists in the manner of securing the tilting mechanismo.
Instead of securing the flanks or long sides of the receptacle, as usual, I fix the
same by passing through the centre of the levers A, B where they cross each other,
a pin or screw, so that the levers form a rigid frame adapted to support the receptacle
and to take up equally any lateral vibrations of the carriage, while hitherto this
function has been performed by one lever only.
The connecting device may consist of a set screw, a bolt or pin.
Any other suitable contrivance for securing the levers may be employed for
instance pivoted stops i, sleeves or collars as represented in Fig. I*.
The position of the levers with regard to the receptacle or other articles supported
by the same may be reversed, as indicated by Fig. III, and the pivotal axes of the
levers may be placed above instead of below the receptacle.
The tipping mechanism is applicable for automatic weighing machines (io flour
mills and distilleries); to carriages suspended from wire ropes and running on the
same; to church bells, and generally to receptacles and other bodies which require
a lateral motion in addition to the tilting action.
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. In tipping mechanism a pair of U shaped double levers A CA and B C B, the
arms A B of which are made concave towards the centre line of the mechanism,
for obtaining a greater tilting angle, substantially as and for the purposes described.

page_text: 2. In tipping mechanism a coupling pin k, bolt or equivalent device for connecting
the levers A and B and distributing vibrations equally on both levers, substantially
as described.
3. The inverted tilting mechanism substantially as described and illustrated by
Fig. III.
