EXTENSIBLE FORM 0R DISTBIBUTING ROLLER FOR PRESSES.

Specification of Letters Patent. Y

Patented Feb. 12, 1918.

Application filed November 10, 1917. Serial No. 201,330.

To all whom t may concern:

Be it known that I, JOHN F. OKEEFE, a citizen of the United States, and a resident of the city of New York, Long Island City, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Extensible Form or Distributing Roller for Presses, of which the following is a full, clear, and exact description.

This invention relates to printing presses and has to deal more particularly with form or distributing rollers, and the invention has for its general objects to improve'the construction of rollers so that they can be adjustable as to lengthso as to fit different size printing presses, the roller being so constructed that it can be easily and quickly adjusted without requiring any special skill.

A more specific object of the invention is the provision ofor spindle is composed ofadjustable sections telescopically connected so that the length of the shaft can be varied, and removably applied to the shaft is the sleeve which carries the facing composition of the roller, which may vary in length according to the width of the press or according to the work to be done.

W'ith such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figure 1 `is a longitudinal section of they,

invention as a distributing roller;

Fig. 2 is a plan view of the stock section of the shaft;.

Fig. 3 is a view of one end of the roller with a journal attachment for converting the device into a form roller; 4

Fig. -1v is a detail view of one end of the shaft with a filler interposed between the journal section and stock section;

Fig. 5 is a view of the inner end of one of the journal sections; and

Fig. 6 is an enlarged fragmentary plan View of the stock section.

Referring to the drawing, 1 designates the stock section which has a central cylindrical body portion 2 and end portions 3 of reduced a roller in which the shaftdiameter which enter sockets 4 in the journal sections 5. These sections 5 are of the same diameter as the body portion 2 of the stock and they constitute together with the stock the shaftof the roller. Fitted over the shaft is a metal tube or sleeve 6 of any desired length, which carries the rubber facing com. position 7 of the roller. The reduced por tions 3 of the central section 1 have spaced threaded apertures 8 to receive a screw 9 that passes through an opening 10 in the inner ends of the outer sections 5. By reason of the plurality of openings 8 the outer sections 5 can be moved inwardly or outwardly to lengthen or shorten the roller. When they are adjusted outwardly fillers 11 may be employed, which are in the form of sleeves that lit over the reduced ends 3 of the stock section 1, such fillers being secured in place by set-screws 12 which engage in registering apertures 8 of the centra] section 2. As shown in Fig. 4, the body portion 2 of the stock section is provided with a lug 13 which is adapted to enter the recess 14 in an end section 5 or a recess 15 in the filler 11 when the latter is used.

To facilitate the assembling of the parts the stock section 1 has an index line 16 and the inner end of each outer section 5 has a notch or line 17, Fig. 5, which, by being brought into registry with the line 16, insures the easy insertion of the fastening screw 9. The outer surface of the shaft formed by the central section 1 and outer sections 5 has a line of apertures or depressions 18 spaced a suitable distance apart and into any of these apertures engage set-screws 19 in the ends of the sleeve 6. In this manner the sleeve can be of any desired length and still be fastened securely to the shaft. To facilitate the registering of the set-screw holes of the sleeve with the line of apertures 18, the ends of the sleeve may have notches 20 which are adapted to be registered with an index line 21 on the shaft.

The outer or journal-carrying sections 5 have dtachable journals so as to adapt the roller for use as a distributing roller, as shown in Fig. 1, or a form roller, as shown in Fig. 3. The outer end of each section 5 is formed with a threaded stud 22 on which is threaded a long journal attachment 23, Fig. 1, or a short journal attachment 24, Fig. 3. The long journals 23 move axially in the bearings 25 of the press frame so that the roller can properly distribute the ink.

rThe journals 24 have shoulders 26 which prevent longitudinal movement of the form roller, Fig. 5, since the journals 24 cannot move back and forth in the bearings 27.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation Will be readily understood by those skilled in the art to which the invention appertains, and While I have described the principle of operation, t0- gether with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrativeand that such changes may be made When desired as fall Within the scope of the appended claims.-

Having thus described my invention, li claim as new and desire to secure by Letters Patent:

1. A press roller of the class described comprising a shaft composed of a central seotion and end journal-,carrying sections telescopically connected with the 'central section, a sleeve fitted over the shaft, and a composition facing on the sleeve.

2. A press roller of the class described comprising a shaft .composed of a central section and end journal-carrying sections telescopically connected with the central section, a sleeve tted over the shaft, a com- Maasai position facing on the sleeve, and removable journals on the end sections.

3. A press roller of 'the class described comprising a shaft composed of a central portion having reduced ends, journal-carrying sections having sockets for receiving the ends of the central-section, means for fastening the sections together in different positions of adjustment, a sleeve fitted over the sections, a composition facing carried by the sleeve, and means for fastening the sleeve in fixed relation to the said sections.

4. A roller comprising a shaft composed of a central section having reduced ends, said reduced ends being provided with a plurality of spaced, threaded apertures, end journal-carrying sections fitted over the reduced ends of the central section, a filler in the form of a sleeve on the reduced ends of the central section and between the end sections and the middle portion of the central section, set-screws passing through the end sections and lillers and engaging in the said threaded apertures to secure the sections and fillers in place, the fillers and sections having interlockinglugs and recesses, a sleeve tted over the sections and secured thereto, a facing composition on the sleeve, and a removable journal on each end section.
