PRINTING MACHINE.

Application :filed November To all 'whom t may concern:

Be it known that I, WILLIAM M. BACON,

a citizen of the United States, residing at Chicago, Cook County, Illinois, have invented a new and useful Improvement in Printing Machines, of which the following is a specification.

This invention relates to printing presses.

An object of the invention is to provide a new and improved printing machine for producing two impressions or prints from a single application of paint to the forms supported on a form cylinder.

Another object of the invention is to provide a machine of novel and improved construction, having the parts arranged in a new cooperative relationship to obtain the desired results hereinafter set forth.

Another object of the invention is to provide a printing machine comprising a form cylinder mounted in a movable carriage,r

and improved means for controlling the cylinder to obtain proper results from the operation thereof.

Other objects will appear from the following description, reference being made to the accompanying drawing, in which- Fig. 1 is a plan view of my improved machine. y

Fig. 2 is a side elevation o-.f the machine.

Fig. 3 is a vertical cross sectional view on the line 3-3 of Fig. 1.

In the embodiment shown, the frame of the machine comprises two parallel side members 1 secured to and supported by legs 2 and connected by transverse frame members 3 intermediate of the ends of the side members 1, and by transverse frame members f1 at or near the ends of the sidemlembers of the frame. The parts of the frame per edges of the sup-ports 5r and the vertif cal flanges of the tracks extend downwardly `against the outer sides of the supports 5.

The tracks are. rigidly secured to thesup-y ports 5.

The form impression cylinder 7 is supported for rotation in a longitudinally mo-vable carriage operatively imounted on the .riage, the standards 11 at each side being separated by a vertical space 12. A frame or box 13 1s rigidly secured in the space 12 between each pair of standards' 11, being retained in place by a plate 14: attached to the upper ends of the standards. A jour nal bearing 15 is adjustably supported in each box frame 13 and is capable of vertical movements to different adjusted positions therein. The axial shaft 16 of the impression cylinder 7 is journaled for rotation in the bearings 15 so that by raising or low'- ering said bearings the form impression cylinder may be accurately positioned for operation upon the work. Each journal bearing 15 is supported by a threaded rod or spindle 17 with which the bearings have swiveled connection of well known construction and arrangement. The spindles .17 are engaged in threaded holes in the plates 141 and have hand wheels 18 on their upper ends for manual engagement whereby the said spindles may be opera-ted to raise or to lower the journal bearings 15 in order to effect accurate adjustment of the form cylinder.

The forms may be secured to the cylinder in any satisfactory way, the form of attac-hment being immaterial to the present invention. y

At each end of the form impression cylin-V der a drum 19 is secured. The form cylind-er and also the drums are rigid with the shaft Y16 and, therefore, are relatively rigid.

A rope or cable 2O is wound a number of times around each of the drums 19, the ends of therope or cable extending to the endsv of the machine and thence to points of connection with proper parts of the machine. If desired, the ropes or cables: 20 iat the ends o-f the machine `may pass over sheaves or rollers 21. The ropes or cables are held from endwise movement so that when the carriage is moved in either direction, the form cylinder in the carriage is necessaril rotated. The carriage may be moved bac and forth by hand or otherwise as desired. Between the center and one end of the frame a device for supporting the paint to be applied to the forms on the cylinder is mounted. As Shown, said device comprises a slab 22 of slate or other appropriate material adapted to support the paint and serve as a palette. The carriage is moved to roll the formy cylinder over the palette, the forms on the cylinder taking up the paint as the cylinder turns. It is sometimes desirable toi raise or to lower the palette to conform to the raised or lowered adjustment of the form cylinder. To permit such adjustment the palette is mounted on adjustable supporting spindles V23 equipped with hand wheels 24, whereby said spindles may be turned to raise and to lower the palette. The spindles are operatively supported by the transverse frame members 8. This construction and arrangementwill be readily understood since it is the same as the arrangement Vby which the work table is supported an d which will no-w be described.

'The work table is adjustably supported between the center and the opposite end of the frame from the palette. As shown, the work supporting table comprises a number ofwooden boards 25 arranged side by side to form a perfectly smooth upper surface and having their adjacent edges secured together by keys 26. The boards 25 are attached to transverse supports 27 which are vertically movable in order that the work supporting table may be adjusted properly with respect to the form cylinder. rThe supports 27 are carried by spindles 2S extending through the transverse frame members 3 and having threaded engagement with plates or blocks 29 mounted on said transverse frame members. The lower end of the spindles 28 are provided with hand wheels 30 whereby the spindles may be Yturned to raise or to lower the work supporting table. y As will be. clearly understood by reference to Fig. 3, the drums 19 at the ends of the form cylinder 7 are concentric with the axis of the Yform cylinder and are of slightly larger diameter. The arrangement is such that when the kfo-rmsare on the form cylinder they will operate properly upon theV work when the form cylinder is rotated as an incident to the movement of the carriage 8.

In operation the paint is applied to the palette 22 by a brush or otherwise, and the carriage isr moved to rotate the form cylinder above the palette, causing the forms to take up the paint. After paint has been applied to the forms, the carriage is moved Vin. the opposite direction to cause the. form cylinder to apply paint to the work upon the work supporting table. The palette and the work supporting table may be adjusted relatively to each other and to the form cylinder; so also the form cylinder may be ad justed relative to the other parts.

From the foregoing it will be seen that my invention completely obtains all of its intended objects and purposes. The machine is of simple construction and arrangement and is efficient in operation. The parts may be easily adjusted as required in the character of work to be performed.

It is apparent that the construction and arrangement may be varied without departure from the nature and principle of thein vent-ion. I do not restrict myself unessentially, but what I claim and desire to secure by Letters Patent is: i
