Abstract: 248,128. Marks, E. C. R., (Nonpareil Machine Co.). Dec. 19, 1924. Stopping, starting, tripping, and like arrangements.-A newspaper stuffing machine for inserting sections of a newspaper into an outer cover comprises stacking devices for the covers and for the insert sections, means for automatically feeding the covers and the sections to a trough or like sheet support, means for feeding the cover sheet along the trough and for opening the same to receive in succession the insert sections, means for delivering the complete papers and covers upwardly into a vertical receiver in counted batches, and means for automatically stopping the machine by electrical means if the feeding, stuffing, or delivery mechanism is not working correctly, and for indicating the particular place of disturbance. The machine is driven by an electric motor 1 in an electric circuit provided with an automatic cut-out switch 203, Fig. 20, which is normally closed but is automatically opened by current from a battery 214 when contact is made at either of the contact switches G, H, I, K, J - - J<3>. These contact switches are normally open, but are closed when the machine is subject to certain abnormal conditions such as a double or crumpled feed, omission of the feed, excessive strain of the driving shaft, or if the opening-out plate 99, Fig. 1, fails to work correctly. Simultaneously with the opening of the cut-out switch 203 an electromagneticallyoperated annunciator is operated to indicate the place of the disturbance. Contact G is closed when a double feed occurs and the roller 20a, Fig. 7, is raised to an abnormal amount. Contact H is closed by a swinging panel 105, Fig. 1, if a crumpled cover a is fed into trough G. Contact I is closed if the cover a is not opened correctly. Contact K is closed if the complete paper is not delivered correctly to the delivery apparatus' but jams at the end of trough G. Contacts J - - J<3> are closed if the automatic feed fails to advance a section to the feed-rolls 21, 20a or the corresponding feed-rolls for the other sections. Near each pair of feed-rolls is an oscillating feeler which is normally prevented by the presence of a paper section from making a contact. The contact is made, however, if the feed fails. In the circuit of each device is a rotary timing- contact which limits the operation of the contacts J - - J<3> to the period in which the paper section is normally passing between the rolls 21, 20<a>. The driving-shaft of the machine is formed of two jointed parts connected together by a weak pin which breaks if an excessive strain is put on the shaft. The relative movement of the two parts of the shaft causes a spring contact to complete a circuit from a commutator brush through the machine to an annunciator and to the switch 203. The electric circuit also includes a spring-pressed contact 256 which tends to rise under the action of springs 259 to open the circuit, but is normally closed by a bar 260 which can be inserted in apertures in a wheel on the driving-shaft to adjust the machine by hand. The machine cannot be driven electrically while the bar 260 is inserted in the hand driving-wheel.
