The invention relates to a new and useful improvement in .machines for printing or embossing. .1t relates especially to machines ing'niember which is actuated to be pressed into engagement with the die and then `raised and then the die is moved out from alinement therewith and the work Yholder .containing the work'is moved into aliiienient with the printing member which is then operated to printv the work on the holder,

then .the printing member is raised and the work holder is withdrawn.

llheA invention is-espeeially applicable to machines for printing or vembossing on glass,

china, porcelain, `enamelled goods 7or other brittle-or frangible articles although it is .not limitedfto machines for printing on articles of that character.

The present invention relates especially to `the `means `foractuating the work holder.

v The linvention will be fully understood from the following description when taken in connection with-the accompanying drawings andthe-novel features thereof will be lpointed out and clearly defined in the claims atthe closeof this `In theedrawings: Fig. 1 is a fragmentary .sideelevationof a specication.

Any suitable mechanism Vmay be ktlm' ployed for this purpose. shown -in the drawings, the die carrier 17 isconnected rwith a rack 18 which engages with `a vgear 19 mounted o n the lshaft 2Q which may be driven-by any suitable ymechanism yto rotate the said shaft on its airis alternately in opposite directions and thereby -to move .the said rack 18 forward and Eback kto-arry the die into position'undertlie printing member and then to move the die back out from -under the printing member wlieiithe printing member rises. -An inkingroll 21 .is provided above the path .of niovementof the die so that the die Willengage with the inlring roll. 21. The dieL will also .pass under ythe `wiper l22 which runs under Vguide rolls 23'to wipe olf the surplus ink.

A `work holder 24is niouiitedon a swingling karm 25 which nearoneendis mounted .fast on a vertical stud 26 pivoted in a bearing 27 so .that rsaidarm 2 5 may swing in a horizontal plane, lThe work holder 24 is shown as provided with upwardlyextending pins 28, 28 adapted to engage with perforatio'ns or recesses in the work to hold the Work steady onthe holder. i

The said stud 2 6 carries agear 29 which .engages with a rack inoiinted ona reciprocable slidebar 31. Said slidebar Sl'also carries a rack 32 whose teetliengage with a pinion33inoiintedon shaft 2Q.

to swing through 18()O or any other pre-e determined arc of rotation to bring the work holder 24: directly under the printing member 15.

lVhen the die 111 moves 'foward the right, it will as already described move back to the position shown in dotted lines in Fig. 1 and iii so doing will kpass beneath the inking roller-21 and in engagement therewithso as to be inked by said roller.l

Mechanism is provided for raising and lowering `the plunger 13 at proper intervals to successively receive the impression from the die and transfer the impression to the Mechanism for actuating the plunger is not shown here as it does not form apart of the present invention but any suitable mechanism may be employed for the purpose to be operated either by hand or power.

lVhat- Iv claim is:

1. A machine of the character described having a vertically reciprocable printing member, a pivotally Amounted work holder Y adapted to be turned on its pivot into and out of alinement with the printing member,

Yamovable die having thereon the design to be printed and adaptedV to transfer the design to theprinting surface when the die and the printing surface are brought into engagement with each other,A means for moving the die into and out of Valinenient with the printing member and means for turning said work holder to move the work into and out of 'alinenient'v with the printing member.
