PRESS STOPPING DEVICE Original Filed Sept. "7. 1928 fw zvg W Patented Aug. 4, 1931 UNETED STATES PATENT OFFICE YORK, ASSIGNOR TO WOOD NEWSPAPER N. Y., A CORPORATION OF VIRGINIA PRESS STOPPING DEVICE Application filed September 7, 1928, Serial No. 304,582.
This invention relates to a device for stopping the press when a choke occurs in the folding couple of a folding machine. The principal object of the invention is to provide simple and effective means whereby the occurrence of a serious'choke will connect up the stopping circuit and stop the press.
Reference is to be had to the accompanying drawing which is an end view of the bearings of a folding machine showing a preferred embodiment of this invention ap plied thereto.
Many chokes occur in the folders between the cutting and folding cylinders and several means have been provided for separting these cylinders when such choke occurs. However, where the separation is great enough to cause the knife to stop cutting the web into sheets and where the pressdoes not come to a stand-still quickly enough, a winder takes place and frequently results in breakage of the folder. This invention is designed to bring the press to a standstill immediately when a winder takes place between the cutting and the folding cylinders.
For the above purpose, the cutting cylinder 10 is mounted on pillow blocks 11 which are secured in place by bolts 12 which pass through elongated openings 18 through the pillow blocks. The folding cylinder 14 is of the usual construction preferably. Now when a choke occurs, the pillow blocks on which the cutting cylinder is carried will slide back until a contact 15 on one pillow block engages a contact 16 adjustably mounted on a bracket 17 insulated by a layer 18 from the frame 19 of the folder which carries the bracket. The contacts 15 and 16 are connected by wires 20 to the stop button control of the printing press and when the contact is made asabove described necessarily the press is brought to a stand-still at once.
Renewed January 5, 1931.
This constitutes a very simple and inexpensive means for preventing these chokes causing serious winders and for preventing the winders that are formed from injuring the folder.
Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art with out departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is 1. The combination with a folding couple, of a circuit connected with the stop button control of a printing press, and means whereby when a choke occurs between the folding cylinders, said circuit will act to stop the press.
2. The combination with a folding couple comprising a cutting cylinder and pillow blocks on which the cutting cylinder is mounted, said pillow blocks being normally held in position but capable of being moved back away from the folding cylinder under a serious strain, and means on the pillow block for closing the stop button circuit of the press to cause the press to be stopped.
8. In a folding machine, the combination with a folding couple and bearings for the two cylinders thereof, pillow blocks carrying the bearings for the cutting cylinder, said pillow blocks being mounted on the frame, an electric contact on one of the pil low blocks, a second contact mounted for engagement by the first contact when the pillow block moves, and a circuit connected with a stop button circuit and arranged to be closed by the engagement of said contacts.
4. In a folding machine, the combination with a folding couple and bearings for the two cylinders thereof, pillow blocks carrying the bearings for the cutting cylinder,
said pillow blocks being mounted on the frame, bolts for holding the pillow blocks in position, the pillow blocks having elongated openings for said bolts, whereby under great pressure between the cylinders the pillow blocks will be forced back, an electric contact on one of the pillow blocks; a bracket mounted on the frame and insulated therefrom, a second contact adjustably mounted on said bracket for engagement by the first contact when the pillow block moves, and a circuit connected with a stop button circuit and arrangedto be closed by the engagement of said contacts.
In testimony whereof I have hereunto afiixed my signature.
OSCAR CHARLES ROESEN.
