Abstract: A sheet delivery mechanism of the type in which printed sheets are deposited by an endless conveyor upon a pile, the front of which is defined by vertical guide members. When it is desired to remove a sheet from the top of the pile for control purposes a supporting finger is interposed above the pile at the forward edge for temporarily intercepting the subsequent sheets, and the guide members are retracted so that the control sheet may be removed. It is the primary feature of the invention that provision is made for time delay, for example, by using a lost motion connection, to insure that the guide members are not retracted until the finger is fully interposed and to insure that the finger is not withdrawn until the guide members are fully restored to working position so that there will be hiatus during which a sheet might travel beyond the pile. In one embodiment, a mechanical linkage is interposed between the manual operator and the finger, whereas in another the finger is moved by a power actuator energized by a manually operated control device. To further insure that the supporting finger is fully inserted upon arrival of a sheet, the manual control is interlocked with a triggering device on the sheet conveyor, so that it is the conveyor which performs the ultimate triggering of the mechanism. In addition to defining the front edge of the pile, the guide members are oscillated back and forth through a small angle thus jogging the edge of the pile but with the jogging movement being automatically terminated when the guide members are retracted. In one of the embodiments of the invention interposable fingers are provided at both the leading and trailing edges for temporary support of the subsequently fed sheets to permit removal of the entire pile and substitution of a new platform upon which the intercepted sheets are deposited to begin a new pile.
