The carriage is provided with a tilting device that is fastened to a carriage frame and is equipped with a push rod which is used to tilt a transporting tray disposed on a horizontal shaft. When the transporting tray is being tilted, for example, a postal package disposed on the tray is transferred at a preselected destination, for example, to a chute. A locking device equipped with detent pawls, an adjustment disc and a locking disc, automatically locks the transporting tray in its predetermined oblique position. In this way the transporting tray is prevented from tilting back once a sliding block provided for the pivoting is no longer in engagement with the tilting device in the region of the tilting path. The sliding block can thus be shorter than the tilt path. ## Claims ### Claim 1 A carriage for a conveyor for piece goods, the carriage including a transporting tray mounted on the frame of the carriage and a tilting device for tilting the transporting tray, wherein the transporting tray is automatically locked in the oblique position intended for the discharge of a piece of goods and adjustment means are provided for unlocking said oblique position by means of the tilting device, and wherein, in order to produce a lock on a horizontal shaft, there are provided a locking disc that is connected with the transporting tray and an adjustment disc that is connected with the tilting device, there being further provided at least one pivotal detent pawl that is connected with the frame of the carriage so as to be in engagement with the locking disc in said oblique position. ### Claim 2 (depends on 1) A carriage as defined in claim 1, wherein a release arm of the tilting device is fastened to the locking disc, with said release arm being placed preferably against the underside of the transporting tray in order to tilt it. ### Claim 3 (depends on 1) A carriage as defined in claim 1, wherein the catch element of a lock support is disposed at the underside of the transporting tray and a catch spring is connected with the carriage frame so as to engage in a detent groove of the catch segment when the transporting tray is in the horizontal position. ### Claim 4 (depends on 3) A carriage as defined in claim 3, wherein an abutment support is disposed at the carriage frame in order to limit the pivoting range of the transporting tray and said abutment support simultaneously serves as a carrier for the catch spring. ### Claim 5 (depends on 1) A carriage as defined in claim 1, wherein the transporting tray, when seen in the direction of movement, can be tilted to the left or right. ### Claim 6 (depends on 5) A carriage as defined in claim 5, wherein the tilting device includes a two-armed release arm that radially projects from the shaft, with the one part of the arm being placed against the carrying tray in the one pivoting direction and the other part of the arm in the other direction. ### Claim 7 (depends on 5) A carriage as defined in claim 5, wherein the locking disc is provided with four locking projections and the adjustment disc is provided with four adjustment cams. ### Claim 8 (depends on 1) A carriage as defined in claim 1, wherein the tilting device includes at least one push rod which can be moved vertically in order to tilt the transporting tray. ### Claim 9 (depends on 1) A carriage as defined in claim 1, wherein the tilting device is provided with a lever in the lower portion of the frame, with said lever being articulated to a push rod and to the frame and being provided with a roller which, in order to pivot the transporting tray can be brought into engagement. ### Claim 10 (depends on 8) A carriage as defined in claim 8, wherein said push rod is moved vertically by means of a sliding block. ### Claim 11 (depends on 9) A carriage as defined in claim 9 wherein said roller is brought into engagement by a sliding block.
