9 Claims.

This invention relates to card printing machines and the object of the invention is to provide a machine for printing cards in which the pressure applied in the printing operation may be varied by means of a leverage controlled manually by the operator.

Another object of the invention is to provide a card printing machine including a printing bed and a card holding means at one end of the printing bed, the said card holding means being releasable by the operator when the carriage is moved to position over the card holding means.

A further object of the invention is to provide a card printing machine comprising a printing bed having a card holding means at one end and a carriage movable longitudinally of the printing bed, said carriage carrying a pressure roller and a member adapted to be turned in one direction to move the pressure roller into engagement with the card and adapted to be turned in the opposite direction when over the card holder to release the card holding means.

Another object of the invention is to provide an eccentrically mounted pressure roller including a pivoted supporting member having a handle whereby the pressure on the pressure roller may be varied by varying the angular position of the handle in'moving the carriage longitudinally of the printing bed. I

A further object of the invention is to provide a spring actuated card holder comprising a pivoted card holding member having an edge arranged to engage and grip the card and the pivoted card holding member being turnable on its pivot against the tension of the springs to allow release of the card.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is a plan view of a card printing machine embodying my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is an enlarged section taken on line 44 of Fig. 1.

Fig. 5 is an enlarged section taken on line 5-5 of Fig. 1.

Fig. 6 is a reduced section taken on line 6-6 of Fig. 5.

The device, as shown more particularly in Fig. 3, comprises a printing bed I which is supported on two channel side members 2 which are se- 1934, Serial No. 730,790

cured to the printing bed I. A track 3 is secured to the opposite longitudinal edges of the printing bed. A carriage bracket 4 is provided at each side of the printing bed I and these carriage brackets 4 each carry a series of four rollers 5, 6, l, and 8, as shown more particularly in Fig. 4. The rollers 5 and 8 are each flanged rollers, as shown in Figs. 3 and 4, and the flanges ride against the outer edges of the printing bed i and the track members 3. By this arrangement the carriage brackets 4 may be moved longitudinally of the printing bed in either direction. An elongated U-shaped member 9 is provided, as shown in Figs. 1, 3, 4, and 5, and each end of this U- shaped member is provided with a pivot stud III which is rotatably mounted in the corresponding carriage bracket 4.

A shaft l l is mounted in the ends of the U- shaped bracket 9 eccentric to the axis of the pivot studs l0 and a roller 12 is rotatably mounted on the ball bearings l3 supported on the shaft II. A handle I4 is also secured to the center of the U-shaped member 9 whereby the member 9 may be turned on the studs ID which act as a pivot for the member 9. By this arrangement, as will be understood from Fig. 4, the roller l2 may be turned from the position shown in full lines in Fig. 4 to that shown in dotted lines in the said figure. The type l5 are mounted on the printing bed I, as shown in Fig. 5, or in any other suitable manner and a transverse member 16 is secured to the printing bed I by the screws IT. This member i6 is provided with lugs l8, as shown in Figs. 5 and 6, and a plate I9 is provided having depending lugs 20 extending between the lugs I8 and a pin 2| extends through the lugs l8 and 20 so that the plate 19 is pivotally mounted on the twopins 2|, shown in Figs. 5 and 6. This plate I9 is provided with a downwardly bent flange 22 at the forward edge and at the rear edge a coiled spring 23 forces the member l9 upwardly on its pivot 2| to force the clamp jaw edge 22 downwardly toward the top surface of the member IS. A guide 24 is secured to the plate l9 and forms a guide for the coiled spring 23. A cross member 25 is provided for the carriage, as shown in Figs. 1, 4, and 5, which extends between the two movable side carriage brackets 4 and is secured thereto by the screws 26 which extend. through the adjacent member 4 and are threaded into the ends 21 of the cross member 25. By this arrangement, the member 25 rides with the movable carriage and a pair of pins 28 are supported in the cross member 25 on the springs 29.

Threaded through the ends 2'! of the member 25 are a pair of adjusting screws 30 which are engaged by the faces 3! of the U-bracket 9 when in the position shown in full lines in Fig. 4. These screws 36 are adjustable and act as stops to limit turning movement of the member 9 on the pivot studs H] by means of the handle l4. The screws 33 may be so adjusted that the maximum amount of pressure with which the roller l2 presses downwardly on the type is accurately limited.

In operation, the carriage is moved to the position shown in Fig. 4 in which position the upturned end 32 of the track 3 provides a stop. At this time, the handle l4 may be turned from the position shown in full lines in Fig. 4 to that shown in dotted lines. When so turned, the pivoted member 9 engages the upper ends of the two pins 28 and forces these pins downwardly against the tension of the springs 29. In this position shown in Fig. 4, the pins 28 are directly over the rear portion of the clamp member I9 and thus force the clamp member downwardly against the tension of the springs 23. This raises the forward edge 22 of the clamp away from the member [6 allowing a card 33 to be positioned on the type I 5 so that the edge of the card may be inserted between the clamp edge 22 and the transverse member l 6. At this time, the handle l4 may be turned from the position shown indotted lines in Fig. 4 to that shown in full lines. In this movement, the pins 28 are released to upward movement by the springs 29 and the clamp member !9 is released to turning movement on its pivot 2| by the springs 23. This causes the edge 22 of the clamp member H) to grip the edge of the card between said clamp edge and the member l6.

As the handle I4 is turned over to the position shown in full lines in Fig. 4, the roller I2 is brought into contact with the upper surface of the card 33, at which time, the carriage is ready for movement longitudinally of the machine. The handle M is then in the position shown in Figs. 1, 2, and 3 and the handle may be grasped in order to draw the carriage longitudinally of the machine. In this connection it will be noted that the more pressure exerted in pulling down on the handle the more pressure is applied to the card 33 being printed and the amount of pressure that can be so applied may be limited byadjustment of the adjusting screws 30. The operator, by grasping the handle I, moves the carriage to the right of Figs. 1 and 2 and the rollers 6 and 8 may engage the screws 34 at the end of this stroke which form stops for the carriage. The carriage is then pushed back by means of the handle M to the position shown at Fig. 1, at which time, the handle may be turned over to the position shown in Fig. 5 and in dotted lines in Fig. 4 to release the card 33. At this time, the type may be again inked and a new card inserted in position to be printed. I have not shown the type in Figs. 1, 2, 3, and 4 as any suitable means maybe provided for supporting the type which maybe arranged in accordance with the design to be printed on the card.

When the carriageis moved'longitudinally of the printing bed and the roller is pressed downwardly by pressing downwardly on the handle [14, downward pressure is applied to the rollers 6,

shown in Fig. 4, and upward pressure is applied to the rollers 1 shown in said figure.

This freesthe rollers 5 and 8 from pressure so that there is no grinding action between the flanges of the rollers 5,and 8 and the a j m structions and, at the same time, is limited in its downward pressure by said adjusting screws 33.

From the foregoing description it becomes 65* dent that the device is very simple and eificient in operation, will not easily get out of order, is

composed of few parts and is of consequent low manufacturing cost and provides a device which accomplishes the objects described.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is-- 1.
