UNITED STATES PATENT OFFICE.
WHEEL FOR PRINTING-PRESS INKING-ROLLER TRUCKS.
Application filed March 19, 1921.
To all 11) item it may concern Be it known that I, LEROY J. VVA'RNER, a citizen of the United States, residing at North Chicago, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in lVheels for Printing-Press Inking-Roller Trucks, of which the following is a specification.
In some forms of printing-presses the composition inking rollers for the form are carried on a truck having rollers running on suitable tracks whereby the path of travel of the inking rollers is determined by the shape and position of the tracks or rails.
In such styles or types of printing-presses it is desirable to provide some means for adjusting the positions of the inking-rollers relatively to the type or printing form so that the correct inking function may be consummated without cutting or mutilation of the comparatively-soft gelatinous-like rollers which apply the ink.
If such inking rollers are not properly positioned, either they are likely to be clamaged or injured by the type or rule lines, or else they may not suitably and efliciency apply the ink.
Accordingly, the present invention aims to supply simple means for effecting such adjustment of the inking-rollers by equipping the inking-roller truck with mutually exchangeable wheelsof differing diameters, and in the preferred embodiment of the invention the tread portions only of the wheels are interchangeable for ones of larger or smaller size.
Thus by varying the diameters of such wheels which roll on the stationary tracks the distance of the inking-rollers from the printing-form may be made anything desirable to produce high grade work without undue or excessive wear on the soft composition-rollers which distribute the ink over the form during their rolling action thereon.
In order that the sizes of the several sets of tread rings for such wheels may be unvarying, they are preferably constructed of metal or other suitable material as distinguished from soft rubber, the latter seemingly not possessing the most suitable characteristics for this purpose.
In the accompanying drawing, forming a part of this specification, to which reference should be had in connection with the following detailed descriptlon of the con- Specification of Letters Patent.
Patented Nov. 1, 1921. Serial No. 453,837.
struction and mode of operation of a preferred embodiment of the invention, and throughout the views of which drawing like reference characters have been employed to designate the same parts Figure 1 is a face view of one of the improved and novel printing-press inkingroller truck-wheels, its shaft being shown in section; a
Fig. 2 is a central, longitudinal section through the tread-ring of the wheel, the other complementary parts of the structure being shown in full lines; and
Fig. 3 is a cross-section on line 3-3 of Fig. 2, the parts being viewed in the direction indicated by the arrows.
By reference to this drawing it will be seen that, as is usual and customary, the wheel is mounted on and keyed to its shaft, the latter having the reference numeral 7 and the key the designating index 8.
v The wheel proper, characterized as a whole as 9, isinternally equipped with a suitable ke'yway receiving the key or spline 8, whereby the shaft and wheel necessarily revolve as a unit.
Such main-body of the truck-wheel has a reduced cylindrical hub portion 11 at one end and a narrow, cylindrical, outstanding flange 12 at the other end, the round intervening part 10 between the two being of an intermediate diameter, all as is fully depicted in Fig. 2.
The central section 10 is supplied with an outwardly projecting key 13 extending from the flange or rim 12 longitudinally across about one-half of the length of such section.
A round tread ring 16 of metal or other appropriate material fits snugly over such intermediate part, bearing at one side against the adjacent face of the flange and having a keyway 17 receiving the key 13, thus securely uniting the parts together to act as a unitary structure.
Such tread or surface member is demountably or detachably maintained in place by reason of a shallow annular groove 14 in the face of the part 10 near the hub section 11 accommodating a longitudinally curved or bowed spring 15 having one end 18 bent inwardly and firmly held in a cavity in the bottom of the groove, the spring between its ends bowing outwardly beyond the cylindrical surface of the part 10 and bearlng against one face of the tread member 16 to hold it in position and against lengthwise displacement, the free end of the spring occupying the groove at all times and hence guiding the spring during its'contraction.
Such locking or retaining spring may be of any appropriate length, but in the present instance it extends around the wheel somewhat over ninety (90) degrees. V As is portrayed in Fig. 2, the inner portion of the face of the tread element toward the flange is beveled or chamfered at 20 for a purpose hereinafter indicated.
Several sets of these tread members are provided, all of the same internal diameter to properly fit the main body oi the wheel, but all of the plurality of sets of different external diameters, thus affording the operator a range of choice, whereby the wheels may be made of any selected diameter over all as occasion requires.
To remove the tread element so that it may be replaced by one of different size, the workman presses inwardly on the central part of spring 15 thereby causing it to bodily recede into groove thus unlocking or releasing the member 16 and permitting it to be withdrawn lengthwise off of the Wheel proper.
The new tread element is then applied longitudinally over the central part 10 of the wheel, its inclined or beveled surface 20 automatically contracting the spring and pressing it inwardly into its annular channel, thereby permitting such tread member tobe slid over the spring onto the part 10. It is then turned on such internal body until the keyway 17 is in register or alinement with the key 13, whereupon the tread element may be pushed fully home against the flange 12, the spring automatically expanding out of the groove, because it is no longer covered and confined therein, thus locking the tread member in place. 7
This invention is susceptible of several satisfactory and convenient embodiments and accordingly it is not confined and restricted to the details of structure of the one appliance illustrated and described.
