Claims. (o1. 91467.8)
This invention relates tofinking rollers of the type employed for distributing ink on printing machinery? More particularly, the invention is cording to the invention with a cutaway portion showing the core construction,
directed to the resilient inking rollers which are used in a distributing system which feeds ink.
from a suppljrjbreaks it up into a film of uniform thickness andconsistency, and transfersthis ink Resilient inking' rollers presently usedcomprise a central rigid shaftor core around which is cast or moulded a layer of resilient material such as a compound of glue and g y r rubber, or
other suitable material. This layer is cast,
moulded; or machined to a specific outside. di ameter in order, that the roller may rotatingly contactother rollers inja train, or contact a moving printingsurfacek There is a tendency with sometypes of compound coveredrollers, particularly those in which the compoundconsistsof'a mixture of glue and glycerine, for the cast or moulded compound to reach its melting point during extremes of temperature or service. v This melting and failure 00-,
curs first at the core of the roller where the metal core and resilient composition join, and, after primary failure atthe core, the roller will usually break down completely due to the stresses of contact under which it operates.
It is an object of this invention to provide a roller whichwill not melt down during the most severe conditions of operation. A further object is to provide a roller, the core of which may be.
kept at a temperature well below the temperature of the room and which is designed for efficient transfer of heat. l
It is also an object of the invention to provide v a roller core of improved design which has a of the physical embodiment of the invention constructed according to thebest modes so far devised for the practical application of the principles thereof, and in which:
Figure 1 is a perspective view of a roller acthru the roller and its core,
Figu're 2 is ajragmentary'longitudinal section Figures is'a transverse section thru the roller and core at 33 FigureZ, and 1 Figures 4 and 5 are side views partially cut away showing alternative core arrangements,
The-general type of roller system with which my roller is used comprising ink fountain, ductcr ro1ler,ink drums, vib-ratorrollers, and distributor rollers is well known in the artand requires no specialdescription herein. V
The resilient roller, Figure 1; includes a core,
generally indicated at ll], covered With a resilient composition I 2. The core is mainly of hollow steel tubular construction as shown in'Fi'gures to support the roller forrotation about itslongitudinal center, Bearingsurfaces "ll, concentric with-the roller'core, are included on the outside end of the gudgeons, the opposite end l8 of f gudgeonsl i being fitted to the interior end of the tube |6by pressure fitting; welding, or thelike so that the core and gudgeon are, for practical purposes, integral: Q
Each gudgeonis bored throughout its entire length toprovidefor the passage of a gas or fluid cooling medium used 'to carry heat away from the hollow core. The bearing ends I! of the gudgeons may be threaded on the inside as shown in Figure 3 for the purpose of adapting a suitable coupling to supply and carry away a cooling medium during rotation of the roller.
The exterior surface of the tubular core center is provided with radially projecting metal fins l5,
spaced about the circumference of the tube I6 and extending for the full length of the core center. These fins are of relatively thin section securely imbedded in the tubular core centen. They are sufficient in quantity and dimension so that the conduction of heat between the metal core and the resilient compositioncoating of relatively high heat flow resistance approaches or equals the conduction of heat between a cooling medium of relatively low resistance to the now of heat and the inner metallic surface of core H).
The exterior surface proportions of the core may diiferfor various materials used, both in the construction of the core and also in the resilient surface. Other factors which will determine, to some extent, the required exterior surface area of the core are the operating conditions, which affeet the quantityzof heat conducted to the core.
Alternative fin construction may be employed .medium within the tubular core center.
to substitute for the longitudinally disposed fins as shown in Figure 1. Figures 4 and 5 show alternatives, where in Figure 4 the fins I5 are applied to the core center in spiral fashion, and in Figure 5 fins l5" are applied transversely of the core center in disc form. However, it is preferred to use the longitudinal or spiral fin construction as shown in Figure l or Figure 4 respectively inasmuch as there is added resistance to bending stresses gained by adopting one of these types. As a consequence of using one of these types of construction with an improved section modulus compared to the conventional cylindrical roller core, it is possible to reduce the material used and effect a saving in this manner.
The core may be kept cool by contact circulation of air or any other satisfactory gas or liquid It may be desirable to have the cooling medium enter the tube at one end, pass thru the inner opening anddischarge from the other end or; it may be found more desirable to have the intake and discharge on the same end. In the case of the latter, one of the gudgeons would necessarily be blocked off on its end to the passage of the cooling medium. e
In application, the primary essentials are to facilitate the transfer and limit the storage of heat at the surfaces where the composition contacts the roller core, and to provide relatively larger contact surface to materially decreasethe concentration of heat to be dissipated.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changesin the shape, size, andarrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. In a resilient roller for inking, in combination, a metallic core, a plurality of metal heat transfer surfaces integral with and projecting from the outside surface of the core, and a resilient composition contacting said heat transfer surfaces and forming a cylindrical inking surface.
2. In a resilient roller for inking, in combination, a hollow cylindrical core, a plurality of metal heat transfer surfaces integral with and projecting from the outside surface of the core, and a resilient composition contacting said heat transfer surfaces and forming a cylindrical inking surface.
3. In a resilient roller for inking, in combination, a hollow cylindrical core, two concentric supports integral with the ends of the core, heat transfer surfaces integral with and projecting from the core, and a resilient composition contacting said heat transfer surfaces and forming a cylindrical inking surface.
4. An inking roller core comprising a tubular central portion, a plurality of heat transfer fins projecting from the outside surface of the tubular central portion, and gudgeons integral with the ends of the core to suport it for rotation about a central longitudinal axis.
5. An inking roller core comprising a tubular central portion, a plurality of heat transfer fins projecting from the outside surface of the tubular central position, and gudgeons integral with the ends of the core to support it for rotation about a central longitudinal .axis, at least one of said gudgeons including a communicating passage from the interior of the tubular central portion to the outside of the gudgeon.
6. An inking roller core comprising a cylindrical central portion and heat transfer fins secured to and projecting outwardly from said central portion.
'7. An inking roller core comprising a cylindrical central portion and heat transfer fins secured to and projecting radially outwardly from said central portion.
8. An inking roller core comprising a cylindrical central portion and spirally disposed heat transfer fins secured to and projecting outwardly from said cylindrical central portion.
9. An inking roller core comprising a cylindrical central portion and heat transfer fins secured to and projecting transversely from the cylindrical central portion.
10. An inking roller core comprising a cylindrical central portion, longitudinally disposed web sections radiating from said cylindrical central portion, and concentric supports integral with and projecting from the ends of the cylindrical central portion.
