l ToaZZ whom t naa/y concern:

Be it known that I, BENJAMIN B. HILL, formerly of Springfield, in the county of Hampden and State of Massachusetts, but now ol' Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Self-Inking Hand-Stamps, of which the following is a specification and description.

My 'invention is an improvement in that class of hand-stamps in which the die-block is adapted to be provided with two or more printing-dies, either one of which may be used to make the impression and be automatically inked therefor at each successive downward and upward movement of the handpiece in the ordinary operation of printing with the stamp and it consists in such a construction of the die-block and its appendages that said die-block can be turned independently of the guide used for holding/the dieblock while it is moving downward in the main frame to give the impression, as will be more fully hereinafter described, an dillustrated in the accompanying drawings, in which- Figure I is a front view of a self-inking hand-stamp having my invention applied. Fig. II is an end view of the same. Fig. III is a vertical transverse section of the stamp through the inking-bed and parts below on the line D I) of Fig. I. Fig. IV is'a vertical longitudinal section of the die-block and its reversing-guide with the pivot connecting the two in elevation Fig. Vis a plan of the same parts. Fig. VI is an end view of the die-block and its reversing-guide. Fig. VII is atransverse section through the'reversing guide, showing the end of the die-block in a partially-reversed position, as in the act of turning in the operation of printing; and Fig.

- VIII is a longitudinal vertical section of one end ofthe reversing-guide, showing the springcatch which retains the die-block in its desired position in the guide.

In the drawings, A denotes the stationary frame of an ordinary self-inking.hand-stamp; C, the tube containing the actuating-spring; l, the movable frame with the hand-piece secured toits upper portion and ordinarily a die-plate pivoted in the lower end of the movable frame. Instead, however, of` the ordinary die-plate used, I pivot what might more properly be termed a die-block, as 10, in

the lower end of the movable frame, having any desired number of sides,y each adapted to have a diesecured thereto or made thereon.

In the drawings a die-block having three sides is shown which is provided with a journal-bearing, as ll, at each end, preferably equidistant from the sides of the block, and which journal-bearing may be continuous, extending the entire length of the block,fas shown in Fig. IV, and the ends of this pivot or journal may be grooved to receive a springring at each end after beinginsertedinto place. y In place of the. ordinary guide usually em- \ployed with this class of stamps to reverse the position of the die while in operation,

with the die blockV or plate, I use a movable guide or yoke, 7, which is so connected to the die-block that the latter can be moved independently of the guide when it is `desired to substitute another face of the die-block for the one in use.

The guide or yoke 7 is shown as lpivoted upon the journahor is attached-thereto at one other end, and is there pivoted or attached to that end of the journal; and this yoke is provided with a longitudinal slot, as 5, at one end, and atthe other is provided with aspring catch or detent, as S, whose end projects inward toward the die-block and engages with any one of a series of indents, as 9, made in the end of said die-block, the number of said indents being equal to the number of sides of the block having dies attached.

One end of the stationary frame A is provided with a vertical slot, as 3, and a bar, as 2, is-pivoted midway its length to the inside of said frame -by the side ot' this slot with a pin, 6, projecting inward from the lower portion of said bar and into the slot 5 in the yoke 7.

The lower ends of the movable frame l are pivoted to the journals ll of the die-block, and a pin, as4, projects inward from the upper portion ofthe movable frame l, which, when the said frame is moved down, passes down in the slot 3 in the stationary frame A, and against the inner curved edge of the vibrating bar 2. As the movable oractuating frame l moves down, the journal 1l at one end of the diebloek first strikes against the inner edge of the' lower part of the vibrating bar 2, moving the end, and extends around the block 10 to its,

which guide is fixedly attached to or formed a fullf half-turn backward, and vresuming its f block also, which is held llower'end Vofl the latter outward, and as the pin in the lower end of the vibrating vbar projects into the slot 5 in the yoke 7, at a point quite j near to th ej ournal 11, the main part ofthe yoke -is moved to oneside ory partially turned upon the journals 11, partially turning the diefast to the yoke. The die-block being thus turned somewhat morefthan one-fourth of a revolution, as the actuating-frame l is moved farther' down, the pin 4 in the upper part of said frame strikes against the curved inner edge of the upper 1 end of the vibrating bar 2, moving its vupper end out-ward and its lower end and proj eeting pin 1nward,`and causing the 'yoke and the diec block, held fast by the detent 8, to make a a full half-turn upon the journals 11,'when the die-blo'ek will be in a reversed position from that which it occupied when the actuatingframe was in its most elevated position, and the die will, in this lower and reversed position, make an impression upon any material placed beneath to receive it. In the upward movement of the actuating-frame l, thejournal 1I at the end of the die-block iirst strikes against the'inner-curved edge of the lower end of the vibrating bar, and moving its projecting pin and the yoke to one side, and causing the latter and the die-block to partially turn back again on the journals l1, and as the frame andjournals Il move upward, one end of the latter strikes against the inner curved edge of the vibrating bar at its upper end'and throws. it outward, and its lower end and its projecting pin inward, causing the die-'block to make original` position before it was moved down. Vhen in this elevated position, the same die which made the impression at the last down- -ward movement of the frame'l will rbe held by the frame up against the inking-pad located and exposed in the lower side' of the part B of the stationary frame A, and will'thereby receive the ink necessary for making the next aimpression at the neXt downward movement ofthe hand-piece and actuating-frame l; Any one of the dies of the three on the three-faced die-block I() may thus be used for making successive impressions, and if any one of the dies is being used, andit is desired to use one of the others, the block 10 may be rotated upon the journals Il, springing the detent 8 out of iisrecess, and when the desired die is exposed for use, or in a position opposite the yoke v7, 'the detent 8 will then spring into the appropriate` recess, as 9, and the die-block be held in the same position until it isagain turned with the fingers to expose the desired die.

In the illustration a die -bloek isr shown having three faces,to each of which a die 1 rmay be secured different in its character orA printing-matter from either of the others; but

' it is obvious that a die-block having any desired number of faces may be used, each having a die different in character ormatter from the others, which is oftentimes a matter of noA little convenience.

I am aware that ,stamps having four-sided die-blocks have been proposed, the faces' of.

which wereintended to be used in the sameY manner as mine; but in this case there were as many reversing-guides as there were faces to the die, and the die-block and guides `were permanently fastened together, while in my improvement there is but one guide, and the die-block can be moved independentIy of thev guide, so as to bring either face ofthe die into operation as required.

It is-evident that the desired number of de-l tents may be made in the end of the die-block and arranged toA engage in an indent made in the inside of the guide 7 ,if desired; but I prefer the construction hereinbefore described.V

If it is desired to have more than one diebloek, the journal maybe disengaged from its bearings in the -lower end of the frame l, the die-block thereon removed from the journal and another slipped onto the journal, and the latter again secured in its bearings in the frame, all with very little trouble. In this manner a great variety of printing may be done with one stamp by having the desired variety of die-blocks, one being removed and another being substituted when desired.

One o, or more of the faces of the die-block may have a recess, as 15, therein, in which to insert type to be used for dating purposes in connection with the permanent die made thereon or secured thereto. y

Having thus described my invention', what I claim as new is 1. The combination, in a self-inking stamp, of a die-block having a number of sides, each roo of which may be brought into action as the printing-surface, and a guide for controlling the position of the printing-surface while giving the impression, the two being adj ustably connected and constructed, substantially as described, to move together while giving the impression, and to allow the die-block to move independently of the guide when desired, to

bring a different' printing-surface into action,`

as set forth. l

2. In a hand-stamp, the combination of a fixed frame provided with an inking-pad exposed on its lower side, an actuating-frame, a revolving die-block having a number of sides, as described, and pivoted upon journals haviro ing a bearing in said actuating-frame, an oscillating -yoke loosely embracingthe ends of 12o said die-block, and a spring detent or catch mechanism vbetween said yoke and die-block,

so that the latter may be revolved inthe yoke i to bring and retain either of its printing-dies into position `to be used for printing, and for having the ink automatically applied for printing by the movement of the actuating-frame in the operation of printing, substantially as described. I
