Philadelphia, county of Philadelphia, and
State of Pennsylvania, have invented certain new and useful Improvementsin Inking-Rollers, of which the following 1s a full, clear, and exact description.'
The object of the present invention 1s to provide an inking roll for printing presses, with a surface which will overcome the disadvantages incident to the use of the ordinary gelatin roll. In the modern newspaper printing press there vmay be as many as one hundred inking rolls, all of the gelatin type, and these rolls are subject to wide variations due to changes in atmospheric humidity and in temperature. It is the usual practice, at the beginning of printing operations, for the pressman to adjust all of his rolls, so that the pressure between the rolls .provides for a contact of about 2; in width. Upon the maintenanceof this contact d epends, in a great measure, the proper distribution of the ink on the rolls. As a result of the extended contact, the surface of the gelatin roll is constantly being iiexed'and, due to the friction between the surfaces, heat is developed and this, in addition to a rise in the room temperature, often results in the contacting surface being extended from i to in Width, thus preventing the roper distribution of the ink on the rolls. these characterisitcs of the gelatin roll, it is frequently necessary in hot humid weather, to replace the gelatin rolls two or three times a day.
Moreover, under ordinary conditions of temperature and moisture the gelatin roll deteriorates very rapidly, and frequently, will not ontlast a days work. This requires the substitution of new'rolls, thus delaying the printing operations. When the surface of a gelatin roll has become unfit for use it is necessary to remake the gelatin portion on the roll in its entirety.v
With the view to overcoming these and other disadvantages attending the use of the ordinary gelatin roll, I have designed a roll which will be understood by reference to the accompanying drawing in which- Figure 1 is a longitudinalsection of one form;
ue to lig. 2 a transverse section through Fig. 1; an
Fig. 3 a partial longitudinal section of another form.
In the preferred form of myinvention vshown in Figs. 1 and 2, the numeral 10 design ates a shaft upon which is mounted a cylindrical core 11 of metal, wood or other suitable material. Vulcanized to the outer surface of the core 11 is a shell of relatively hard rubber 12 formed, at its periphery, withilanges 13. Vulcanized to the base of relatively hard rubber 12, and confined between vthe flanges 13 thereof, is a surface 14 of relatively softy rubber constituting the inking surface of the roll. The end flanges 13 prevent the lateral spreading of the soft rubber surface, thus maintaining thejdiameter of the roll substantially uniform under the conditions encountered in practice.
Instead of supporting the inking'surface upon a base of relatively hard rubber, I may support it directly upon the center core 11 as indicated in Fig. 3. If desired the surface of the core 11 may be roughened, in order to secure a firm contact between the core and the rubber sheathing, in either of the forms shown in Figs. 2 and 3.
The advantages of the rubber covered roll are that it has better ink transferring qualities than the gelatin roll, and because of the contact, which is about 51; in width, the soft rubber roll enables a much better and cleaner application of the ink to the type to be made than is the case with the gelatin roll with its relatively wide contact surface with the inking roll. Again, the soft rubber roll is not affected, as is the gelatin roll, by changes in temperature. and humidity, enabling the softrubber roll to run without change, for considerable periods of time, vmany lasting for six. months daily use. The life of the soft rubber roll is therefore, very much longer than that of the gelatin roll, and even when worn to such extent that it has become inefficient or defective in its operation, its surface can be ground or bufed to restore it' to substantially its ori inal condition. This reuse of the soft ru beil roll by the simple operation of refacing by subjecting its surface to a buiing operation, results in a material saving in the expense of purchasing and maintaining the rolls. An advantage of the hard rubber confining anges is that they may be easily ground olf to compensate for the reduction of the size of the roll caused by the refinishing operation.
As an example of the method ofmaking a compound of the soft rubber surface,
would say that I have found that a compound consisting of 20 lbs. of rubber yand `1i! lbs. of sulfur vulcanized for a period of live hours at 280 Fahrl has given the best results. I l
Having thus described-my invention, what I claim and desire to potect by Letters Pat` 3. A printing roll Acomprising a core having peripheral anges, and an inking surface of soft rubber supported upon said core between the flanges.
4. A printing roll comprising a core of relatively hard rubber having peripheral anges, and an inking surface of soft rubber supported upon the core between said flanges.
A printing roll comprising a base of face of soft rubber vulcanized thereto.
6. A printing roll comprising a base ofl lrelatively hard rubber and an inking. surrelatively hard rubber-formed with peripheral flanges, andv an inking surface of soft rubber vulcanized thereto. l
7. Avprinting roll comprising a supporting member, a layer of hard Vrubber vulcanized thereto,and an inking surface of relatively soft, rubber vulcanized to the layer of hard rubber.
