Referring to the drawings indetail, the numeral 1 indicates generally a relatively tall housing, and the numeral 2 indicates generally a relativelyshort housing arranged forwardly of the housing 1. The housings 1 and 2 are provided with a common bottom wall 3. The housing 1 includes a pair of side walls 1,

a rear wall 5, a top wall 6, afront wall secion 7- depending fromthe top wall '6, and a front wall section 8 extending upwardly from the bottom wall 3. The front wall section 7 is arranged forwardly of the front wall section 8 with the loweredge of-the section 7 arranged in a materially higherpla'ne than the upper edge of the section 8.= The side walls 4: are recessed asindicated' at 9 to a point substantially in vertical alignment with the wall section'8. -=EXtending fronithe wall sec -on S tothe rear wall 5 isa'horizontal partition 10, and extending from the partition '10 to the bottom wall 3 is'a vertical partition 11. lhe partitions 1O and-11, in conjunction with the walls of the housing 1 divides the latter into what will be termed a'printinghead compartment 11, a motor compartment 12. anda lamp compartment 13. Disposed with- 1 in thecompartment 12 is a motor 1 1 for 0peratinga suction element indicated generally at the motor being adapted for connection with an electrical socket 16. Disposed 5 within the compartment 13 is a lamp 17 which is connected with an electrical socket 18.

The'housing 2 includes a pair of side walls "19, a front wall 20, anda top wall 21 which extends in continuation of the horizontal partition 10. The front wall section 8 of the housing 1 also forms the rear wall of the housing 2. Disposed within the housing 2 is a horizontal partition 22 and a vertical partition 23 which divide the interior of the housing 2 into what will be terme-d a reflecting compartment 2% and a lamp compartment Disposed within the lamp compartment 25 is a lamp 26 which connected with an electrical socket 27. Disposed within the compartment 24 is a supporting member 28 for a forwardly and upwardly inclined mirror 29 which is adapted to reflect upwardly light rays passing from the lamp 17 through an opening 30 in the wall section 8 adjacent the mirror 29. The top wall 21 is formed with an opening 31 which extends entirely across the top of the compartment 24, and which further extends substantially across the top of the compartment 25. The partition 10 is providedwith a pair of ventilating openings 32 for the compartment 13.

Mounted on the wall 21 and partition 10 is a stationary frame 33 upon the side nembers of which is mounted a sliding frame 34. The side members of the frame 34 are longitudinally grooved as indicated at 35 to receive the upper portion of the side members of the frame 33 therein and to lower the end members of the frame 34 in order to bring the same into alignment with the end members of the frame 33 whereby the end members of the frame 33 provide stops for limiting the sliding movement of the frame 34. The frame 34 is manually slidable and is provided at its forward end with an upstanding lug 36 for conveniently operating the frame. Carried by the frame 34 is a glass carrying frame 37 which is maintained in position by a series of lugs 38 projecting upwardly from the frame 34. The frame 37 is provide 1 with a.

glass 39. Carried by the rearward portion of the frame 37 is a border forming mask 40 which is disposed in alignment with the re fleeting compartment 24 when the frame 34 is disposed in its extreme forward position. Hingedly mounted at the forward end of the frame 37 is a skeleton mask 41 which is in alignment with the reflecting compartment 24 when the frame 34 is disposed in its extreme rearward position.

Extending through an opening 42 in the partition 10 is a curved suction pipe 43, the rearward end of which is in communication with the suction element 15 and the forward end of which is provided with a hollow printin g head 44. The suction pipe 43 is pivotally mounted on a bracket 45 mounted on the partition 10. Extending across the bottom of the head 44 is a flexible pad 46, and er:- tending through the pad 46 and bottom of the head 44 'are a plurality of openings 47. Projecting upwardly from the head 44 is a lug 48 to which is pivotally connected one end of a link 49. The opposite end of the link 49 is pivot-ally connected with a crank arm 50 which extends though a slot 50 in the wall section 7 and is adjustably mounted on an operating shaft 52 extending transversely of the housing 1 and j ournaled in the side walls 4 of the latter. The shaft 52 is provided at one end thereof with crank handle 53 for operating the shaft. Adjustably mounted on the shaft 52 is a crank arm 51 which extends between side flanges 54 on a rearwardly extending bar 55. The flanges 54 project forwardly from the upper face of the bar 55 whereby the bar is provided at its forward end with a recess 56. The for ward ends of the flanges 54 are pivotally connected with the crank arm 51 in spaced relation to the rearward end of the latter. Carried by the rearward end of the bar 55 is a rod 57 which extends downwardly through the opening 42 and is pivotally conneoted at its lower end to a lever 58 which is provided at its forward end with a shutter 59 normally closing the opening 30 through the wall section 8. The lever 58 is pivotally mounted at its rearward end on a post 60 projectin upwardly from the bottom wall 3. The head 44 is normally maintained in the elevated position shown in Figure 3 by means of a spring 61, the respective ends of which are connected with the suction pipe 43 and a rod 62 carried by a pair of uprights 63 disposed within the housing 1 adjacent the side walls of the latter.

Projecting rearwardly from the shaft 5 2 is a crank 64 to which is pivotally connected the forward end of a link 6". The rearward end of the link 65 is pivotally connected with the upper end of a lever 66, the lower end of which is pivotally connected to a bracket 67 projecting forwardly from a post 68 extending upwardly from the partition 10 adjacent a rearward corner of the housing 1. The lever 66 and bracket 67 are formed of electrical conducting material and the link 65 is formed of insulating material. Secured to the forward face of the post 68 is an insulating base 69 which is provided with a pair of spaced contact members 70 and 71. The contact members 70 and 71 are formed of resilient material with the member 71 arranged above the member 70.

Carried by the head 44 is a numbering device which includes a lever 72 pivotally mounted intermediate its ends on a bracket 73 projecting upwardly from a platform 7 4 formed on one side of the head 44. Projecting laterally from the lever 72 adjacent one end of the latter is stationar tud 75 upon which is mounted substantial y U-shaped bracket 76. Rotatably mounted on the stud 75, between the side members of the bracket 76, are a pair of flanged discs 77 which are maintained in spaced r-eiation by means of a washer 78 interposed therebetween and rotatably mounted on the stud 75. Extending around the flanges on the discs 77 and the closed end of the bracket 76 are a pair of endless, indicia carrying bands 79. Adjacent the bracket rearwardly of the latter, the platform 74 provided with an adjusting screw 80 for limiting the dormward movement of ti The lever normally maintained in en.- gagement with the screw 80 by means of a spring 81, the respective ends of which are earward end of the lever 7'2.

-' connecte'drwith the upper end of the bracketa 73 and with the lever 72 at a point in spaced :relatiomto the bracket forwardly of the latter.v The lever'72isprovided at its rearward end with a'downward pro ect-ion 82:

which engages a stud 83projecting upwardly from the rearward end member of the sliding frame 34. Slidably mounted on the bottom. wall of the head 44, and confined within a recess84 in the lower face of the platform 74, is a tray 85 upon \VlilClLlS mounted an ink pad 86. Pivctally connected with the 44:is in its elevated 'position the ink pad 86 1 is moved forwardly by the rod 87 for supplying ink to the 1nd1c1a carrying bands 79. When the head 44 is in its lowerec position bracket 76 when the projection 82 is brought the tray 86 is moved rearwardly by the rod 87 to permit a downward movementof the into engagement with the stud 83. The hot- I tom Wall of the head 44 and the pad 46 are formed with an opening 88 in vertical aligninent with the bracket 76.

The electrical circuits for the machine in- I clude a pair of conductors 89 and 90 which are adapted for connection with a source of electrical supply, and which are further con- I nected with the terminals 91 for the lamp socket 27. The conductor 89 is connected by means of a branch 92 with the bracket 67, and

the conductor 90 isconnected by means of branches 93 and 94 respect1vely with the 4 motor socket 16 and lamp socket 18. The

motor socket 16 is further-connected by means of a conductor 95 with the contact member 70 while the lamp soc ret-18 is further connected by means of a conductor '96 with the contact member 71. It will be seen that the lamp 26 will be energizedupon the passage ofcurrent through the conductors 89 and 90 without .energizingthe motor 14 or lamp 17.

The circuit for energizing the motor 14 isclosed when the lever 66 is brought into con' tact with the contact element 70. while the circuit for energizing the lamp 17 is closed when.

thelever 66 is brought into contact with the contact member 71.

In the operation of the machine current is admitted to the conductors 89 and 90 to energize the lamp 26 in order that the rays of the latter may be passed through the opening 31 to render the sliding frame 34 clearly vis ible. The frame 34 is then moved to its rearward position as illustrated in Figure 3.

, A negative or the like is then placed beneath causes a lowering of the printing head 44 against the tension of the spring 61 until the flGXlblG pad 46 is brought into engagement with the object to be printed for holding the latter in position; Upon the downward movement of the head .44, the crank 64 moves the link 65 rearwardly whereby the lever 66 is first brought into contactwith the contact member 70 for closing the circuit for the tmotor 14 whereby the suction element 15 is to permit the passage of the rays from the zlamp 17 through the openings 30, such rays being projected onto the mirror 29 and re flected therefrom through the opening 31. The shutter 59 is elevated when the rearward end of the angular bracket 50 is brought into engagement with the lower face of the bar 55 which causes the latter to be raised, carrying the rod 57 and lever 58 therewith.

1 After the printing of the negative'as aforesaid, the crank handle 53 is released to per mit the head 44 to be elevated by the action of the spring 61, such action breaking the circuit for the motor 14 and lamp 17; Owing to the suction within the head 44, the object --is again actuated by means of the crank handle 53 which causes the head 44 to lower the printed object into :position'with; respect to 'theborder forming mask 40. The crank ha lidle 58 is then again released-to permit the upward movement'ofthe head 44, after which the-printedobject may be removed'therewfrom.

-Upon' eachdownward movement of the 'head 44, the projection 82 on the lever 72 is brought into engagement with the stud 83 on bands 79 into engagement with the object being printed for .stampmga number or the 7 like on the latter.- Each time the head 44 is elevated, the tray85 is slid forwardly by the rod 87 for supplying ink to the indicia carrying bands 79.
