ALVIN E. MOWREY, OLE FRANKLIN, PENNSYLVANIA.

PRINTING-PRESS.

To all whom it may concern:

Be it known that I, ALVIN E. MOWREY, citizen of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

The object, construction and utility of my invention are herein set forth with suflicient clearness to enable those skilled in the art to which it appertains, to make and use the same.

J ob printing presses of the type commonly known as the Gordon press have not, as heretofore constructed, been provided with any means for adjusting the ink-rollers, with relation to their pressure upon the face of the type which is being printed from, and to which the rollers apply ink. It is often necessary that an adjustment of this nature be made, there being various reasons for this necessity, some of which are: The ink rolls may vary somewhat in diameter, and particularly a roll may be somewhat larger when it is new than it is after it has been in service for a period of time, also a small form does not require as much pressure of the roll upon the face of the type to properly apply the ink as does a large form; there are various other reasons well known to those skilled in the art, which need not be mentioned. With presses of this type, as at present constructed, it is a common practice when an adjustment of the ink rolls is de sider, to place a strip of paper or card-board upon the track and secure it in place by means of paste or glue. This method of procedure is not only inconvenient, but it is devoid of any considerable degree of accuracy.

It is, therefore, the object of my invention to provide presses of the type specified with an adjustable ink-roller track, whereby the desired adjustment may be quickly, conveniently and accurately made. One form of construction whereby I attain said object is shown in the accompanying drawing, which is a side elevation of the bed of a press of the type mentioned, and shows the same equipped with my adjustable ink-roll track. This construction is as follows :The track 1, upon which the metallic rollers or wheels at either end of the ink-rolls travel, is separable from the bed 2, and is so attached thereto that it may be moved or adjusted Specification of Letters Patent.

Application filed October 14, 1912.

Patented Dec. 23,1913. Serial No. 725,600.

. outwardly and inwardly, and for the purpose of making said adjustments quickly and accurately, I provide the screws 3, 3, which pass revolubly through the front portion of the bed and enter a tapped hole 4: provided therefor in the rear edge of said adjustable track 1. To the rear end of each of said screws is securely attached a miter pinion 5, 5, which mesh with cooperating pinions 6, 6 secured to the vertically-disposed rod 7, the upper end of which projects above the upper face of the bed 2 and is provided with a wing 8 arranged for the easy and convenient manipulation of said rod or shaft 7. A knurled lock-nut 9 is placed upon said shaft 7 and arranged to contact with the juxtaposed face of the boss 10 and this serves to lock said shaft in any desired position, thus securing the desired adjustment.

The operation of the device is as follows lVhen it is desired to adjust the track outward, (said track being shown in the drawing in the innermostposition), nut 9 is loosened, shaft 7 is then turned thus revolving pinions 6 which revolution is transmitted to pinions 5, 5, and the thereto aflixed screws 3, 3, which will cause the track-section 1 to move outwardly. lVhen the desired adjustment has been reached nut 9 is tightened down upon its seat 10, which looks and secures the adjustment.

Both sides of the bed are equipped as shown, so that the ink-rolls may be caused to travel with a uniform pressure across the entire face of the type to which they are applying ink.

In order to prevent any play, lateral or otherwise, of the track-section, dowel pins, 11, may be employed in addition to other devices such as the shoulders or transverse joints 12.

The drawings are illustrative of my inventive idea, but they are not intended to show the only way in which said idea may be embodied, as many modifications thereof might be devised without departing from the scope of my invention.

I claim:

The combination with the bed of a printing press of the Gordon type, of an ink-rolltrack section adjustably attached to each side of said bed, means for adjusting said sections comprising a revoluble shaft for each of said sections and having bearings in said bed and extending parallel with the ing screw-threads upon one end thereof,

tapped holes in said track-sections arranged for the operable reception of said threaded ends, and a bevel pinion upon the other end of each of said pins arranged to mesh with said shaft-pinions, whereby said pins may 10 be simultaneously turned for the purpose of adjusting their respective track-sections.

In testimony whereof I afliX my signature in presence of two Witnesses.

ALVIN E. MOWREY.
