Abstract: This apparatus is of the kind comprising a fixed frame 1 and a drum 5 having a vertical axis for rotation relative to and within the frame about a vertical axis, this drum comprising an internal cavity intended to receive the objects to be passed and accessible through an opening formed in the vertical wall of the drum, the apparatus also comprising means for stopping and locking the drum relative to the chassis in two diametrically opposite positions.According to the invention, these means for stopping and locking the drum relative to the frame comprise an abutment fixed to the end 12 of the drum and another abutment 17 fixed on the end 8 of the frame, and also an inclined leaf spring which can withdraw vertically out of the way when the stop of the drum passes, the gap e left between the end of the frame and the end of the drum corresponding practically to the vertical dimension of these abutments alone.The invention has particularly advantageous application in government offices, banks, etc.

Abstract: The money passing device is adapted to equip counters having windows and is of the type comprising a bowl inserted in the counter and fictitiously divided into two parts by the extension of a partition wall separating the official from the public.The device comprises a shutter whose dimensions are very slightly less than those of the upper side of the bowl. The shutter is freely pivotable about an axis which coincides with the median plane of the partition wall. The axis is located slightly above the bowl so that, in its horizontal position, the shutter covers the bowl. End-of-travel abutments are provided for limiting the angular movements of the shutter in which the latter alternately uncovers one of the two parts of the bowl while it closes the other opposite part.This device has its application in any counters or counter windows and can be used for passing money, documents or other objects.

Abstract: The lock chamber is employed for the passage of packets or large-sized objects between a room reserved for the public and a premises which is isolated and protected from the public by a safety partition wall. It may be for example employed in administrative services such as post-offices, departmental stores or left-luggage offices of stations or airports, etc.In this lock chamber, the drum has at least one window closed by a transparent bullet-proof material. This window is diametrally opposed to the access opening for supervising the exchange. The drum has end-of-travel abutments and locking means which automatically fix the drum in any one of its loading or unloading positions.
