lNKlNG APPARATUS.

SPECIFCATIQN forming part or" Letters Patent No. l705,184, dated July 22, 1902.

Application filed March 12,

T0 all whom :It muy concerns Be it known that we, LESLIE B. WOODRUFF and FRED E. CATON, citizens of the United States, residing at San Jose, Santa Clara county,State of California, have invented certain new and useful Improvements in Inking Apparatus; and `we do hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to that class of inl ing apparatus in which an ink-supply device of suitable character is located in proximity to the type-forni to be inked,and an independentmanually-operated form-inkingroller deriving its inksupply by contact with the supply device is lifted or moved bodily by the operator forth and back between said supply device and the type-form. This style ofinking apparatus is used in connection with hand piintingpl'esses, in which the type-form is exposed to be inked either by being moved back and forth to alternately receive its ink and to make its impression or by the completion of the stroke of an impression-cylinder rolled over it.

The inking apparatus in one of its usual forms consists of a stand or frame adapted to be set in proximity to the bed of the press upon which the type-form is exposed tobe inked, said frame carrying in its top a pair of ink-supply rollers, usually made of wood and one having a crank for turning them. An independent form-inking roller carried in a handled bail is by the operator alternately passed over and in contact with the .ink-supply rollers and with the type-forin, the operator turning the supply-rollers with one hand whenever the ink is required to be distributed or spread evenly and then bodily lifting or moving the form-inking roller forth and back between the supply-rollers andthe type-form. This lifting or moving of the form -inking roller asis usually done has, among others, the following objections, to Wit: First, unless performed with great care, involving loss of time, the exposed edges of the chase are inked,causing it to soil the sheet to be printed; second, if an ink plate or apron is used, over which the inking-roller passes between the supply-rollers and the type-form, part of the ink is left on the plate, causing an uneven appearance of the printing; third, the lifting or 1902. Serial No. 97,806. (No model.)

moving of the inking-roller is a severe tax upon the strength of the operator, not so much because of the weight to be lifted as because of the prolongation of the operation or, if an ink plate or apron be used,because of the natural cohesion ofthe inking-roller to said plate or apron.

The objects of our invention are to avoid inking the chase, to secure uniformity in inking the forms, to relieve the' tax upon the strength of the operator, and to make the movement uniformly accurate and easily performed.

T0 these ends our invention consists, essentially, in a movable oscillating or reciprocating carrier so disposed as to receive the form-inkingroller from the iuli-supply device Yand.to transfer it under the guidance of the operator and with precision to the type-for1n and to again receive it from the type-form and bear it back again to the supply device.

Our invention further consists in the novel disposition and arrangement of the carrier, as we shall now describe by reference to the `accompanying drawings, in which- Figure l is a side view of our inking apparatusrshowing one form of our carrier and showing also by dotted lines the different positions ofthe carrier and those of the inkingroller. Fig. 2 is a topview of the apparatus of Fig. l, showing the inking-roller on the type-form and the carrier down in position on the chase containing the form and waiting to receive said roller to transfer it back again to the ink-supply rollers. Fig. 3 is a side view showing another form of our inking apparatus'and carrier and its application to the type-bed. Fig. Ll is a top View of same.

' A is the type-bed of a printing-press, upon which lies the type-forni B, and C is the chase holding the form.

D is the ink-supply device, which may be of any suitable character. lt is here `shown in the forni of two rollers, one roller being provided with a crank d for turning it. E is the form-inking roller carried by a bail c, provided with handle c'. These ink-supply rollers are to be placed in convenient proximity to the type-bed A to enable the inking-roller to be transferred forth'and back between the type-form and the supplyrollers- Itis ininiaterial as far as the essential feature of our IOO invention is concerned what kind of a frame carries these supply-rollers or otherinking device or whether said frame is attached'to or is independent of the type-bed A or stand of the press or, ifattached, what kind of a connection is made. For the purposes of illustration we have shown one kind of frame in Figs. l and 2 and another kind in Figs. 3 and 4. In Figs. l and 2 we show the application of our invention to a common form of inking apparatus of this class consisting of the frame as an independent stand F, which carries the ink-supply rollers in its top and which is adapted to be adjusted to its proper place relatively to the type-bed on which the type-form rests.

In Figs. 3 and 4 we show a bracket-frame F', carrying the ink-supply rollers and adapted to be secured', as by the bolts f,' to the frame of the type-bed.

Our ink-roller carrier may be of any suitable shape or construction and may be connected with the stand F or bracket-frame'F' in any suitable manner. Its chief essential is its adaptability to receive and bear the Weight of the inking-roller and to transfer it from the ink-supply device to the type-form and back again. Itmay be an open or closed framework or a pair or series of arms and of suitable cross-section and length. The form of carrier G shown Vin Figs. l and 2 is a trough of the length of the ink-supply rollers, thereby adapting it to receive and hold the form-inking roller irrespective of the length of the latter, so that rollers of differentlengths may be used without adjustment. The form shown in Figs. 3 and 4 is the concavcd ends or heads G' of a pair of arms H', which said ends or heads are adapted to receive the ends e2 of the form-inking roller.

The ink-roller carrier is a movable one, having a travel between the ink-supply rollers and the type-form. Its movement is such as to carry it at one limit into such position relatively to the supply-rollers as to allow the form-inking roller to be rolled directly from said rollers into said carrier, and at the other limit it will lie in such position as to permit the form-inking roller to be rolled out of it upon the type-form. The adjustment of the movement is such that at its forward limit the carrier lies over and protects the chase C, so that the inking-roller will pass directly upon the form without contact with the chase. To effect this movement, the carrier may be mounted in any suitable lnanner. That which we show in Figs. 1 and 2 consists of end links or arms H, connected with it and pivoted at their lower ends to suitable brackets f on stand F. The center of movement is slightly forward of the rear limit of the carrier, so that said carrier will lie at rest against the edge of the frame in which the supply-rollers are journaled and be ready to receive the inking-roller, as seen in Fig. l. It will be observed that the carrier Gr of Figs. 1 and 2 is secured to its arms H by bolts g. By loosening these bolts the carrier may be turned slightly to vary its position relatively to the arms, and thus it may be adjusted readily to lie in the proper position both to receive the inking-roller and to lie on the chase without striking or resting on the type-form.

The form of carrier connection which we show in Figs. 3 and 4 consists of the pair of arms H', secured upon a squared rock-shaft h', whereby said arms swing in unison, with the rockshaft, which is journaled in the bracket-frame F', for a center. To provide for different lengths of form-inking rollers, the arms H' may be secured upon the rockshaft h' adjustably, so that they may slide closer together or farther apart, and'be fixed in position where adjusted by set-screws h2. The form of carrier G' of Figs. 3 and 4 by not coming into contact with the inked surface of the inking-roller will avoid any tendency to disturb said surface.

The operation is as follows: The operator grasping handleeholds the form-inkingroller, presses it forward, and rolls it into the waiting carrier. Then with the inking-roller lying in the carrier he pushes on the handle e, and thereby swings the carrier containing the inking-roller forward until the carrier reaches the chase at the edge of the form. Then he pushes the inking-roller out of the carrier, upon and over the type-form B, and when the latter is inked he draws the inking-.roller tinuous motion, and the same movement is obtained when the inking-roller is returned from the type-form to the supply-rollers. Thus the operator is relieved of the weight and suction of the inking-roller, and said roller is carried with precision between its limits of operation.

Having thusl described our invention, what we claim as new, and desire to secure by Letters Patent, is

l. In an inking apparatus having an inksupply device and an independent, manuallyoperated form-inking roller, deriving its inksupply by contact with said supply device, a movable carrier adapted to travel between the ink-supply device and the type-form, and disposed to receive the form-inking roller from thesupply device and to transfer it under the guidance of the operator to the type-form and back again.
