PROVISIONAL SPECIFICATION.
Transport Cart with Automatically Closing Cover.
I, HUGO MÜHLBERG, 30 Körner Strasse, Leipsic, Cart Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The present invention relates to a transport-cart, the flexible cover of which
closes automatically through the disengaging of a detent, and which is re-opened
by the short turn of a lever.
Fig. 1 of the accompanying drawing is the longitudinal section and Fig. 2 is the
cross-section of a cart of this description.
The lever A, which is connected with the toothed segment B and turns on
pivot II, catches into the pinion E which is firmly connected with the toothed
wheel D, turning together with the latter on pivot III. The toothed wheel D
catches into wheel Z which is firmly fixed on the shaft C.
The flexible cover I, consisting of texture, wood, or metal, is rolled up on the
shaft C.
In order to open the cart, that is to say, to roll the cover I on the shaft C, the
lever is turned into the direction X (Fig. 1), through which the toothed
segment B turns the pinion E, the toothed wheel D, the wheel Z, and the shaft C
in the direction so that the cover I is rolled on this shaft C.
Through pinion E the rack F has at the same time been pushed into the
direction V, and the springs G G', which are connected with the rack F, have
been stretched. Thus the springs G G¹ tend to draw back the rack F, which
action is supported through the construction of the toothed segment which-as the
drawing shows-serves as counterpoise to the lever A.
When the cover is open, the draw-rod H, which is connected with the segment B
and which is provided with a nose P, is pushed through the back wall of the cart
to the place R, and thus the nose P stops the toothed segment B.
When the cart is to be closed by the cover I, the nose P of the draw-rod H is
disengaged at R. The springs G G', supported by the weight of the toothed
segment B, draw back the rack F, and the cover I, of the cart automatically
closes.
The shaft M goes across the box of the cart and serves as a carrying shaft for
the cover I.
K are two narrow straps which roll up and off in the grooves 00 of the shaft C
(Fig. 2) drawing back the cover when it returns.
The rollers N are arranged as guide rollers of the straps K at both sides of the
cart-box.
L L are guide-bars for the cover at each side of the cart-box.
Dated this 20th day of July 1893.

COMPLETE SPECIFICATION.
Transport Cart with Automatically Closing Cover.
I, HUGO MÜHLBERG of 30 Körner Strasse, Leipsic, Germany, Cart
Manufacturer, 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 present invention relates to a transport-cart, the flexible cover of which

page_text: closes automatically through the disengaging of a detent, and which is re-opened
by movement of a lever.
Fig. 1 of the drawing filed with my Provisional Specification is a longitudinal
section and Fig. 2 is a cross-section of a cart of this description.
The lever A, turns on pivot II and is connected with the toothed segment B
which gears with the pinion E which is firmly connected with the toothed wheel D,
turning together with the latter on pivot III. The toothed wheel D gears with
wheel Z which is firmly fixed on the shaft C. The flexible cover I, consisting
of textile fabric, wood, or metal, is rolled up on the shaft C.
In order to open the cart, that is to say to roll the cover I on the shaft C, the
lever A is turned in the direction X (Fig. 1), and moves the toothed segment B
which turns the pinion E, the toothed wheel D, the wheel Z, and the shaft C in the
direction so that the cover I is rolled on this shaft C.
Through pinion E the rack F has at the same time been pushed into the
direction V, and the springs G G', which are connected with the rack F, have
been stretched. Thus the springs G G' tend to draw back the rack F, which
action is assisted by the construction of the toothed segment which as the
drawing shows serves as counterpoise to the lever A.
When the cover is open, the draw-rod H, which is connected with the
segment B and which is provided with a nose P, is pushed through the back
wall of the cart to the place R, and thus the nose P stops the toothed
segment B.
When the cart is to be closed by the cover I, the nose P of the draw-rod H
is disengaged at R. The springs G G₁, assisted by the weight of the toothed
segment B, draw back the rack F, and the cover I of the cart is automatically
closed.
The shaft M goes across the box of the cart and supports the cover I.
K are two narrow straps which roll up on and off in the grooves 00 of the
shaft C (Fig. 2) drawing back the cover when they return.
The rollers N are arranged, as guide rollers for the straps K, at both sides of
the cart.
LL are guide-bars for the cover at each side of the cart.
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: :―
An automatically closing cart-cover for transport carts, substantially consisting
in the flexible cover I which rolls up on the shaft C, and is joined to the straps K
guided over the rollers N, and which, through the movement of the lever A by
means of the toothed segment B, and the toothed wheels E D Z is rolled up on
the shaft C and which by means of the springs G G¹ which act upon the rack F
and the pinion E assisted by the weight of B, after the disengagement of the
segment B by means of the rod H, is automatically drawn over the cart.
Dated this 29th day of March 1894.
