DUPLICATING-MAGHINE.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed January 4,1913. Serial No. 740,222.

To aZZ whom it may concern Be it known that I, Gnoncn ARTHUR VVIL- LIAM RUsHwoR'rH, a British subject, resid- Lancaster, England, have invented certain new and useful Improvements in Duplicating-Machines, of which the following is a specification.

This invention relates to duplicating machines, more particularly to those in which a number of sheets are printed off by means of a wax stencil mounted upon a cylinder or by means of lines or blocks of type mounted upon a cylinder orv in which a duplicate of a letter is taken by impression upon a damp sheet passing between rollers.

In the stencil-carrying machines, it is customary to print in two or more colors by applying pads of different colors to the stencil-carrying cylinder, usually a difi'erent color being employed for .the heading or signature from that employed for the body of the circular or letter.

In type-carrying machines it has been proposed to print in more than one color by an additional roller.

This invention is designed to provide mechanism for printing upon each sheet of paper an impression in the same color as or a diiferent color from the impression printed by the cylinder or bed, so that while a circular letter may be printed with the signature (either in the same or a diflerent color) from the rotating cylinder or bed, the description of the person signing or the name of thefirm or both may be printed in such position that the signature, when printed from the cylinder or bed, will lie adjacent thereto, preferably all'three in diflerent colors.

It consists essentially of an oscillating or reciprocating printing stamp or device mounted upon the frame of the machine, to which stamp or device a downward movement is imparted to print an impression on the paper before being drawn forward by the machine, preferably during such period of the rotation of the cylinder as the paper is at rest.

The invention will be fully described with reference to the accompanying drawmgs.

Figure 1 is a side elevation of a stencilcarrying machine showing the invention applied thereto. Fig. 2 is a similar side elevation showing the position of the parts when Manchester, county of in operation. Fig. 8 is a side elevation of certain parts immediately before 1 being brought into position. of the machine with the stencil-carrying cylinder removed. Fig. 5 is a side elevation of a type-carrying machine showing the invention applied thereto.

Referring to said drawing the invention is shown applied to a duplicating machine with a cylinder A carrying either a stencil or type. The machine is constructed in the ordinary way with the rotary duplicating cylinder A mounted in a frame B and rotated by a handle C, and a paper feed board At the intake or feed end of the machine, a printing stamp. E is mounted above the paper feed board D, which stamp can be operated while the sheets of paper are at rest. The printing stamp E is of rubber, metal, wood or composition and is mounted in a framee in which it can reciprocate and be pressed down upon the piece of paper to be printed, (being preferably of the type of stamp known as a turnover or similar self-inking stamp).

The printing stamp E is mounted in a horizontal frame F which rests upon the pile of paper sheets and from underneath which the top sheet is taken at each revolution of the printing cylinder A.

The stamp is capable of adjustment longitudinally of frame F, owing to the engage ment of the ends of thecross-bar with the bars 7, which latter are arranged longitudinally of the machine and are disposed above the side members of said frame, and it can also be adjusted transversely by moving the secondary frame F toward either side of the machine, this frame F being secured to cross-bar f and having a portion thereof engaged with the longitudinal slot f in said cross-bar. The depression of the stamp causes it to print on the surface of the paper.

The stamp E is operated at every revolution of the printing cylinder by levers G and cross bar H. The position of the bar H is adjustable, sothat it may be set to correspond with the position of the printing stamp E.

In the arrangement shown'in Figs. 1 to 4, the levers G are raised by a pin 9 fitted into one of the gear wheels, which pin en gages a link or connecting rod 9 pivoted to the lever G at one side of the cylinder. As

Fig. 4 is a plan view the machine is rotated the pin g engages a notch in the end of the link g, and said link is raised thereby and stretches the spring 9 As the pin 9 is rotated, the movement of the link g is arrested by the frame B of the machine, and the pin 9 disengages itself therefrom, allowing the levers G to be drawn sharply back by the spring 9 the cross bar H striking the head of the printing stamp E and forcing the latter downward into contact with the paper to impart the desired impression thereon.

In the arrangement shown in Fig. 5, the pin 9 is fitted to the side of the cylinder, and a cam g is attached to the lever Gr. As the pin descends, it engages the cam g and forces the lever G downward, bringing the cross bar H into contact with the head of the printing stamp E and forcing the stamp downward into contact with the paper to impart the desired impression thereon.

v To compensate for the varying thickness of the pile of paper sheets, the lever G is made in two parts or lengths hinged together at 9*. with a spring 9 to hold the two parts of the lever in normal position. A lever constructed and actuated in a similar manner may be applied to the machine shown in Fig. 1. V

What I claim as my invention and desire to protect by Letters Patent is 1. In a duplicating machine, the combination, with a feed table; of a frame mounted thereon and embodying a pair of spaced, parallel longitudinal bars, and a slidable cross-bar connecting the first-named bars; a secondary frame adjustable toward either end of said cross-bar; and a stamp mounted in said secondary frame.

2. In a duplicating machine, the combination, with a feed table, a rotary printing cylinder, and gearing for driving said cylinder, one element of said gearing being provided with a pin; of a depressible printing stamp mounted on said table; a reciprocatory element adapted to strike downwardly upon Copies of this patent may be obtained for the head of said stamp, to actuate the latter; and a member carried by said element for periodic engagement and release by said pin.

3. In a duplicating machine, the combination, with a feed table, a rotary printing cylinder, and gearing for driving said cylinder, one element of said gearing being provided with a pin; of a depressible printing stamp mounted on said table; a reciprocatory element for operating said stamp embodying a spring controlled lever provided with a member adapted to strike downwardly upon the head of said stamp; and a member carried by said lever for periodic engagement and release by said pin.

4. In a duplicating machine, the combination, with a feed table, a rotary printing cylinder, and gearing for driving said cylinder, one element of said gearing being provided with a pin; of a depressible printing stamp mounted on said table; a reciprocatory element adapted to strike downwardly upon the head of said stamp, to actuate the latter; and a link pivoted to said element and provided with a notch adapted to periodically receive said pin. 7

5. In a duplicating machine, the combination, with a feed table, a rotary printing cylinder, and gearing for driving said cylinder, one element of said gearing being provided with a pin; of a depressible printing stamp mounted'on said table; a reciprocatory element for operating said stamp embodying a springcontrolled lever provided with a member adapted to strike downwardlyupon the head of said stamp; and a link pivoted to said lever and provided with a notch adapted to periodically receive said pin.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit IIQSSQS.
