Application filed .iui a,
The invention relates to an improvement in machines for printing. It is especially intended for machines for printing or emembossing on glass, china, porcelain, en-
amelled goods or other frangible articles but it is not limited to machines for Such use. It relates especially to machines in which the printin and embossing member is reciprocable an has a printing surface on which the character, marking on design is imprinted or embossed by a die in such manner that the printing member is adapted to reproducethe design in the work when the printing member and the work are brought into engagement with each other. One ob'ect of the present invention is to provi e a die and a work holder in vertical alinement with each other, means for moving the printing memher alternately into engagement with the die and with the work andmeans for rotating the printing member through 180 at each up-stroke and at each down stroke so that the printing surface will face up ward on its upward stroke and will be inverted to face downward on its down stroke and thereby bring the printing face of the printing member alternately into en- Fig. 4 is a view similar to Fig. 1, Show ing the printing member at'the end of its down stroke in engagement with the work.
Referring to the drawings:
There is shown at 10 a frame or casting to hold the working parts. Slidably mounted in .guideways of the frame is a carrier 11 on which ismounteda die 12 having formed thereon the design to be imprinted or embossed in the work. Said die carrier is slidable in said guideways to bring the die into "and out of alignment with the printing member. Secured to .the
. printing member.
1927. Serial No. 204,272.
underside of said die carrier is a rack13 which engages with a gear 14 on a shaft 15 which may be actuated in any suitable manner to reciprocate the said slide back and forth to move the die into and out of operative position with relation to the At 16 is shown an inking roll which will be engaged with the die 12 when the die passes back and forth over said inking roll. At 17 is shown a wiper to remove the surplus ink from the die. At 18 is shown a stationary work support on which the work to may be placed in position to be engaged by the printing member on the down stroke. 7 v The printing member preferably :comprises a pad 20 of gelatin or other suitable material adapted to receive the impression of the design from the previously inked die 12 when the pad is pressed into engagement with the said die and to reproduce the design on the work when pressed into engagement therewith. The said pad 20 is attached to a holder 21. Said holder 21 is mounted on a horizontalshaft 22 jour nalled in hearings in boxes 24, 24 which are vertically slidable on the vertical guide rods 25, 25. A stud 26 projects outwardly from each of the boxes 24; A lever 27 has branching arms 28, 28 which are pivoted at 29 to theframe of the machine, and each of said branches 28 is formedwith an elongated slot 30, said slots being respectively engaged by the studs 26, 26 whereby the movement of the lever 27 up and down will cause the bearings 24 and the printing member which is journalled in said bean. ings to moveup and down in a straight line.
Mounted on said shaft 22 is a pinion 31 which engages with the teeth of a vertical rack 32 whereby as the printing member is raised. or lowered, the holder for the printing member will be rotated; The gearing between the pinion and the rack and the range of movement of the print-ing member is so adjusted that the printing member will make a half rotation at each full stroke up or down so that when the printing member is in its upward position in pressing engagement with the die, the printing surface will be in a horizontal plane and when it is in the inverted positionof the down stroke, the printing member will face downward and be in a horizontal plane so that it may be pressed squarely againstthe work on the work holder. I
It is desirable that the printing member may be locked in an intermediate position without contact with either the die or the work holder when it is desired to leave the machine at rest either for placing work on the work support or for moving'the die backward to be inked or when the machine is intended to be at rest when not in ope '2 tion. The means provided for this are follows:
Mounted fast onthe shaft 22 is a collar 33 (see particularly Fig. 3) having a horizontal slot in which is a pin 34 seated on a spring 35. The bearing 2i for the shaft formed with a slot t) with which said pin 34 is adapted to engage and which is sprung intosnch engagement when the shaft 22 is rotated to a position where the said pin comes into alignment with the said slot 6 thereby holding the printing member against further movement. Preferably the parts are so adjusted that this locking will take place when the printing member is at a slight distance below the die as shown in Fig. 1 so as to afford clearance sniiicient to permit the die, after being moved to the right for the inking operation. to be moved back into the operative position shown in Fig. 1, preliminary to the complete upward stroke of the printing member to take the impression from the die. The locking mechanism may, however, be so adjusted that the locking will take place at any other intermediate position desired that will permit sutlicient clearance for the positioning of the die and for placing the work on the work support or removing the work there from.
hat I claim is:
1. In a printing apparatus, a die, and a work support in vertical alinement with each other, a printingmember mounted to rotate on a horizontal axis, a vertically slidable mount in which said printing member is journalled, a lever having operative connection with said slidable mount whereby the said slidable mount and the printing member may be moved up and down, and means whereby the printing member is automatically turned at each stroke in either direction so that on one stroke its operative face will engage the die and on its reverse stroke it will engage the work.
2. In a printing apparatus, a printing member, a vertically reciprocable mount in which said printing member is journalled,
a lever having operative connection with said slidable mount whereby the said mount and the printing member may be moved up and down and means whereby the printing member is automatically inverted during each up stroke and during each down stroke that at the end of one stroke its operative face will engage the die and at the end of the other stroke its operative face will engage the work.
3.111 a printing apparatus, a printing member, a rotatable horizontal shaft on which said printing member nn'umted, hearings in which said shaft is journalled, guides on which said bearings are vertieally slidable, a pivoted lever having operative connection with said bearings whereby the bearings may be moved up and moved down and means whereby the printing member is automatically turned on its axis during each stroke in either direction.
4;. In a printing apparatus, a die and a work support in vertical alinement with each other, a printing member mounted on a rotatable horizontal shaft, hearings in which said shaft is journalled, guides on which said bearings are vertically slidable, means for moving said hearings on said guides, means whereby when the bearings are moved up or down the said printing member will be inverted so that at the end of its stroke in one direction, its operative face will engage the die and at the end of the stroke in the opposite direction its operative face will engage the work.
5. In a printing apparatus, a die and a work support in vertical alinement with each other, a printing member mounted on a. rotatable horizontal shaft, hearings in which said shaft is journalled, guides on which said bearings are vertically slidablc, a pivoted lever adapted to be rocked on its pivot in a vertical plane, said lever having elongated slots and said bearings l'iaving studs which engage with said slots whereby when the lever is turned up on its pivot it will also the bearings, shaft and printing member and when it is turned down it will depress the bearings, shaft and printing member, means whereby when the bearings are moved up or down the said printing member will be inverted so that at the end of its stroke in one direction its operative face will engage the die and at the end of the stroke in the opposite direction its operative face will engage the work.
In testimony whereof I atlix my signature.
