PRINTING-PRESS DEVICE.

Application filed March 31, 1924. Serial No. 703,154.

To all whom it may concern Be it known that I, TONY MEAMONE, a-

' citizen of the United States of America, re-

' ta-in new and useful Improvements in Printing-Press Devices, of which the following is a specification.

This invention is particularly applicable to what is known in the printing trade as the Kelly press. Its application and value is not limited to the Kelly press, however, and it will be found useful in many other installations.

The principal object of the invention is to provide means in a press of this type which will prevent the paper sheets from rebounding, wrinkling, 'or otherwise getting out of register when they strike the paper stops of the press.

A further object of the invention is to provide a device of this character in which the. pressure upon the paper sheets can be minutely adjusted and which will not tear or otherwise damage the paper.

Other objects and advantages reside in the detail construction of the invention, which result in simplicity, economy, and efficiency, and which will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Figs. 1, 2, and 3 are sectional views through a portion of an automatic printing press such as the Kelly press, illustrating the use of the invention.

Fig. 4 is a side elevation of the improved.

device which will be designated, in its entirety, as the register stop hereinafter and indicated by the numeral 9.

Fig. 5 is a crosssectional view through the. same.

In order to illustrate the use of the inven tion it will be necessary to describe in some detail the printing press to which it is an attachment. A portion of this press is shown in Figures 1, 2, and 3, the parts thereof being designated as follows: cylinder 16, feed board 17 conveyor belts 18, paper top guide 19, top guide supporting bar 20, lever shaft 21, sheet stop arm 22, sheet stop shaft 23, sheet stop 24, sheet stop adjusting screw 25, sheet detector 26 and sheet detector latch bar 27 i The invention comprises a tube. 10 the lower edge of which is turned slightly inward, as shown at 11. A clamp 12 is affixed to the tube 10 and provided with a. thumb screw 13. One or more steel balls 14 are car ried in the tube 10, the lower one of which will project below the lower extremity of the tube. A removable pin 15 is. passed through the tube 10 to prevent the balls 14 from being shaken out of the tube 10.

In use the invention is clamped, by means of the clamp 12 and the thumb screw 13, to the lever shaft 21 of the press. This shaft also carries the sheet detectors 26.

WVhen the sheet detectors 26 are in the. downward position, and the sheet, designated by the numeral 28, is traveling toward the detectors, the tube 10 will be elevated from the moving sheet, as shown in Fig. 1.

As the detectors travel upward to release the sheet and allow it to move against the. sheet stops 24, the tube 10 will be brought downward to the position shown in Fig. 2, allowing the lower ball 14 to come into contact with the paper. As the sheet moves forward to the sheet stops 24, this ball will roll thereon and when the sheet strikes the stops it will prevent it from rebounding or wrinkling and will hold it in perfect register with the stops 24.

As the stops 24 move upward to release the sheet to the cylinder 16, the sheet will be drawn from under the ball 14, as shown in Fig. 3 and the device will then be raised by the lever shaft for the reception of the next oncoming sheet.

Two or more of the register stops 9, are clamped along the lever shaft 21, according to the width of the paper sheets being fed. When feeding relatively heavy paper the number of balls in the tube 10 is increased to increase the pressure on the sheets and when feeding relatively light paper the number of balls in the tube 10 is diminished to proportionately diminish the pressure on the sheets. v

The present invention has an advantage over spring devices in that the pressure delivered by a spring varies with the degree of.

deflection thereof, while, the pressure delivered by the balls in the applican'ts device is absolutely uniform regardless of the displacement thereof.

The friction between the ball and the sheets is'practically n'il since the balls are loosely confined in the tube 10 and are free to revolve. 7

While a specific form of the improvement has been described and illustrated lrerein,iit is desired and understood that the same may be varied, within the scope otf thesappended claims, Withoutdeparting tromgthe spiritor" the invention. I
