SPECIFICATION forming part of Letters Patent No. 617,147, dated January 3, 1899.

Application filed May 25,1898.` Serial No. 681,674. (No model.)

To all whom it may concern,.-

Be it known that we, ABEDNEGO Dnwns, residing in New York, county of Kings, and State of New York, and ALFRED-SHEDLOCK, residing in Jersey City, county of I-Iudson, and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Manual-Power Presses, of which the following'is a specication.

This invention is designed to meet the d'emand for a simple, efiicient, and powerful manual-power press adapted to be used for various purposes-such as for hot and cold embossing, cutting, printing, ordinary pressing, teand capable of being quickly transformed from one style of .press to another.

The main portion of the press designed by us having the above characteristics comprises a system of levers embracing the toggle-joint principle and arranged to be actuated in the most direct manner with the least amount of frictional resistance, a head to which the power-levers are connected, a base, two rods or standards joining together the head and base, and a follower iitted to slide on and be guided bythe rods and connected to one end of the lever system, said follower being formed hollow, so as to be readily heated when de- The auX- iliaries provided for use with and as parts of the press in adapting it for operation in the carrying on of the diderent processes consist of two or more interchangeable tables of different heights constructed to slide on ways attached to or forming part of the base, so as to be set directly under the follower and to be moved away therefrom for the reception of the article or material to be acted upon, thus providing for the different applications or uses of the press calling for considerable variations of distances between the follower and the table, the follower being provided with means for adjusting it a limited extent only for setting it to suit the work to be done and to produce the required degree of pres-- sure when the parts of the lever system are in right lines or in position to exert the most force, a type-holding chase adapted to be secured to the follower and having a skeleton construction by which the back of the chase is exposed to a free circulation of air, so that the transmission of heat from the follower t0 the type in the chase will be insufficient to affect the ink applied to the type, thus admitting of the press being used as a printingmachine immediately after its use as a heated embossing-press, and so save the time that would be necessary for the follower to cool Off before proper printing could be done if the type or back of the chase were placed in close contact with the follower, and an inking device comprising an ink-plate attached to the base of the press and an inking-roller carried in a frame attached to the sliding table, which in this case is the platen vof the printing-press, said roller being arranged to roll on the ink-plate and to carry ink therefrom to the type in the chase as the table is slid from beneath the chase to have the sheet to be impressed placed upon it. These with other novel features of construction will be hereinafter fully described, reference being had to the drawings, in which Figure l is a front elevation of the press, partly in section, and showing the high sliding table in use therewith. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation of the lower part of the press fitted up as a printing-press. Fig. eiis a front elevation of the follower, showing the skeleton type-chase attached thereto. Fig. 5 is a front elevation of the low sliding table, and Fig. G is a sectional view of one of the universal joints of one of the rods of the lever system.

The press proper consists of the heada, the base b, the vertical connecting standardrods c c, the follower d, fitted to slide on the rods c c, and the power-applying mechanism, which consists of the hand-lever c, the end of which is shown broken awayin the drawings, the lever-arm or crank j, connected to the upper end of the shaft f, which is tted in a vertical bearing formed on the head a at one side'of the press, the hand-lever ebeing secured to the lower end of this shaft, the

connecting-rod g, secured by means of a uni- IOO the universal jointsV being hereinafter described, and a rod of a compound character providing for its longitudinal adjustment pivotally connected to the lower end of the lever by the pin h2 and to the central ears formed on the top of the follower d by the pin d'. This connecting-rod is composed of two similar end pieces t' t", having eyes for embracing the pins h2 and d, respectively, at one of their ends and axially bored and tapped at their other ends, the one with a right-hand thread and the other with a left-hand thread, a right and left hand threaded rod j, fitted in the axial threaded bores of the pieces it', and a sleevej, secured to the central part of the rod j and formed to extend over the ends of the pieces 1' t', so as to cover the exposed parts of the screws and to impart a neat and finished appearance to the rod, the said sleeve being provided with a series of holes by which it and the screws may by a suitable wrench be turned to vary the length of the rod as desired.

Before describing the other features of the press attention is called to the salient features and advantages of this power-applying system of simple levers. In the position occupied by the various parts, as shown in Figs. l and 2, the follower d of the press is in the upper position, it being so held by the spring e', which surrounds the bearing of the shaft f', with its free end acting on the hand-lever e. Now when the hand-leverl e is moved forwardly-that is, toward the front of the press-and when the stop e2 on the lever strikes the rod c the crank-pin of the leverarm f, the axis of the shaft f', and the center of the connection of the rod g and the lever h will be in a straight line, occupying practically a horizontal direction, and the fulcrum and pivotal connections of lever 71, the adj ustable connecting-rod il il', and of the follower d will also be in a straight line of a vertical direction, the follower d being then forced down into its operative position, its adjustment in relation to the work to be done and the pressure exerted by it being controlled by the setting of the double-threaded rod j. The power thus applied, it will be seen, is through the medium of two toggle-joints, the parts of which are so arranged as to be operated under the least amount of frictional resistance, the upper one, composed of the lever-arm or crank fand rod g, having a reverse toggle action and the other one, composed of the lever h and rod if', having a direct toggle action. It will also be observed that all of the parts comprising this compound toggle-lever system are of simple construction and can be cheaply made. The backward movement of the hand-lever e is limited by the adjustable screw e3, and by the setting of which the rise and fall of the follower d is determined.

The universal joints at the ends of the rod g are similar in construction, and a description of one (referring also to Fig. 6) will apply to both, the only difference being one of arrangement, they being at right angles to one another at the ends ofthe rod g. In the eye formed in the end of the rod is fitted to rock therein the plug 7c, and through this, at right angles to its axis, is fitted the rod or shaft 7s', which extends through the elongated openings 7a2 formed through the sides of the rods and projects beyond the same a sufficientdistance to extend into bearings formed in the other member of the joint, which in these cases is either the forked end of the lever 7L or the lever-arm or crank f. By this construction, which is simple, strong, and cheap to make, the rod g is freeto move relatively to the part 7L (referring to Fig. f5) in both horizontal and vertical directions and in different angular positions coincident to the two movements by rocking on the plug k within the limits of the elongated openings k2 and rocking on the pin or shaft 7c', Whose axis is at right angles to that of the plug 7c.

The follower d is, as shown, cast or otherwise formed hollow to facilitate heating it and the die carried thereby. This is suitably done in this class of press by means of gasfiames, the burners for which are shown in dotted lines d2 in Figs. l and 2. The follower is provided with means for holding a die l, here shown as gripping-pieces l lf, held up to the bed by bolts passed through lugs cl3 and set up tightly to the die by set-screws Z2.

Tables of different heights, as m and fn, are provided and fitted to slide on the ways b' ZJ, attached to or forming part of the base b, and the inner Vand outer positions o f the tables Ou the slides are determined by the stops b2 and b3. The higher table m is used when embossing and analogous work is to be done, the table in such case constituting the platen of the press and having the counter' of the die attached to it. The handle m provides a ready device for moving the table out to have the work placed on it and :for setting the table and work under the follower.

Now it is often required in factories where such presses as here described are used to run off a job of letter-press printing immediately after the press has been in use on a heated die-stamping job, and this could not be done if` the type were set directly against the heated follower, as the heat would so affect or dry the ink as to prevent good work being done. Now We save the loss of time that is necessary to allow the press to cool off by making a type-holding chase adapted to be secured to the follower by b olts and of a skeleton character-that is, the chase 0 is provided with only sufficient supports or bearing-lugs o o on its back as are necessary to resist the pressure applied to the chase, and these lugs 0 o" have so little surface of contact with the heated follower d that the transmission of heat through them is not sufficient to materially heat the chase during the time the follower is cooling, and the keeping the chase cool during such time is as sisted by the free circulation of air between IOO IIO

the follower and the chase. lVith this chase vit is necessary to use a low sliding table, as

shown at n, as the platen, and to provide means for inking the type held in the chase o a detachable frame p is secured to the rear part of the table, so as to extend over the inkplate q, which is fitted to rotate in the vertical bearing q', secured to the rear side of the base Z2. The frame p carries two rollers, the forward one, p,bein g the inking-rollerto carry ink from the plate q to the type when the platen-table is drawn from under the chase, and the other roller p2 performs the functions of adistributin g-roller for the ink on the plate q and may be made as a traversing-roller to facilitate the distribution of the ink. The

frame p has a side arm r, extending beyond the edge of and under the ink-plate q, and this arm is provided with a dog or pawl fr', which acts onthe ratchet-teeth q2, formed on the under side of the plate q to partly rotate the plate each time the table fn is moved along the ways b'.

Besides embossing and printing, by means of this press any direct hot or cold pressing may be done, either the high or low table being used, as circumstances may require, and when it is desired to use the press as a cutting-press the low table will be used, the paper or other material to be cnt being placed on the table and the cutting-knife arranged on the material,when the table is drawn away from the follower and the follower caused to act on the back'of the knife to drive it through the material after the table has been set back into operative position.

It is evident that any form or style of press may be used in conjunction with the various auxiliary devices forming part of this invention, and other forms of devices suitable for imparting to a manual-power press the multiplex character or features here described may be used to accomplish the desired ends and would be suggested by the description of the auxiliarydevices here explained, so We do not limit this invention to the exact construction of the parts here shown and described.
