FINGER GUARD Original Filed May 26, 1926 Patented Oct. 18, 1932 PATENT OFFICE HENRY A. WISE WOOD, OF NEW YORK,

N. Y., ASSIGNOR TO WOOD NEWSPAPER MACHINERY CORPORATION, OF NEW YORK, N. Y., A. CORPORATION OF 'VIRGINIA FINGER GUARD Original application filed May 26, 1926, Serial No. 111,787, and April 6, 1929, Serial No. 353,200. Divided and this application filed May 14, 1931. Serial No. 537,279.

This is a division of my applications for patent, Serial No. 111,7 87, filed May 26, 1926 on a high speed printing press and Serial No. 353,200, filed April 6, 1929 on a rotary printing machine.

The chief object of this invention is to provide an improved form of finger guards for warning the operator if his fingers come into too close proximity to the bite between the plate and the impression cylinders and that will not injure the printing plates in case of accident.

Other objects and advantages of the invention will be described hereinafter.

Reference is to be had to the accompanywarning the operator when his fingers come in too close proximity to the bite between the plate and impression cylinders 17 and 18. This guard consists of a very thin tube 60 shown as cylindrical in form. It is loosely suspended on two projections 61 attached to the inside of the frame 14. It is kept in place by a collar 62 on each stud 61. When one collar is shifted to the end nearest the frame, it permits the tube to be taken out by releasing the other end for the purpose of replacement. The tube is made so thin that if it is caught in the bite between the cylinders it will merely be flattened out without any material damage to the plate or blanket. This provides a loose device which will not interfere with the printing but will warn the operator if he gets his fingers into a dangerous position at this point where the surfaces of the adjacent cylinders are moving inwardly toward the bite.

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- 0 out departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect but what I claim is 1. The combination with a printing couple, of a finger guard located adjacent to the bite between the cylinders, comprising a thin metal tube supported in place from the side frames.

2. The combination with a printing couple, of a pair of supports on the side frames extending inwardly a short distance therefrom at a point substantially equally distant between the cylinders and at the side from which the web enters for the impression, and a thin metal tube hung on said supports to warn an operator if his fingers get too close to the cylinders.

3. The combination with plate and impression cylinders adapted to print on a web, of a pair of studs projecting in from the sides a short distance at a point adjacent to the point at which the web enters the space between the cylinders, a thin metal tube hung on the ends of said studs, and collars on said studs for holding the tube in position on them, whereby, when one collar is loosened and pushed back, the tube can be moved along with the collar until the other end is free from the other stud.
