Tascher, Inglcside, Ill., assigner to National Biscuit Company, New York, N. Y., a corporation of New Jersey Application February 1, 1945, Serial No. 575,700 8 Claims. (Cl. 19E-40). 2 l My invention relates to a package delivery chute and has for one of its objects to produce a delivery chute which will deliver with certainty and without damage the lower or first package from a line or stream of packages that are sup plied more or less continuously to its upper end. At Warehouses, factories, stations and other places where trucks or cars are loaded with mer~ 5-5 of Fig. l, showing one of the stops for the tilting extension. Y In the drawing, Ill indicates a chute, which may be one of a multiple series arranged either horizontally or vertically, downwhich packages II, I2 slide that are delivered, more or less con tinually, to the upper end of the chute, either by hand or from a conveyor. , The chute will be inclined at the angle at which it best delivers rchandise, the merchandise in containers and packages is fed by hand or by a conveyor to 10 the parcels. I have found an angle of 221/2 de grees to be satisfactory in most cases, but this the upper end of a chute or chutes leading to angle will vary depending upon the speed de the loading platform. At the delivery end, the sired, fragility of the articles, roughness, and lowest package is removed for loading and the other factors. It is supported on a frame which next following package movesl down to take its may be made from angles I3, Iê, l5 or other 16 place. The pressure of the following packages shapes secured together, as by welding or other against the lowest one, which has been stopped means. At a suitable place adjacent the delivery by a block or abutment, is so great that the wrap end of the chute, as on the frame member I4, per of the lowest bundle or package often is there is pivoted at I6 a tiltable extension which damaged while lbeing removed. An important object of my invention is to'pro 20 comprises a slide I8 that is open at both ends, and at its rear or entrant end is curved down vide means for preventing pressure of the fol ward to form a rounded stop 0r abutment I9. lowing packages against the lowest package when .

The lower end of spring 25 is con' other objects and advantages. nected to any convenient ñxed member, as the Fig. l is a side elevation of the lower end of a delivery chute, with the leading package or bundle at the neutral point where its further ad~ Vance will trip the abutment and stop the fol lowing packages. Fig. 2 shows the abutment tripped and the leading package released from pressure of the following packages. , frame member I5. , - As the package continues to advance beyond the position shown in Fig. l, the entire exten sion tilts about the pivot I6 raising the stop I9 into the path of the next following package I2 which it stops, as shown in Fig. 2. The pack age II continues to slide forward on the slide It’ until it comes to rest against gate 20. “The Fig. 3 shows the package removed from the switchZli .remains closed,y and the spring 26, to abutment, which is new rea-dy to return to the 50 getherwith the pressure of the package, keeps position shown in Fig. l` ready to receive the , the gate ZIB closed. next package. As shown in Fig. 4, the switch 24 and sole Fig. 4 is a wiring diagram for tripping the con noid 29 are in a circuit that includes the push trol solenoid and counter. button switch 30 and a second solenoid SI which Fig. 5 is an enlarged detail, in `section on line actuates a counter.
