EDWARD J ABS, OF ELEMWOOD PARK, ILLINOIS.

PRINTING-FRAME.

Specification of Letters 1:?atent.

Patented Mar. 5, 1918.

Application filed. February 21,1917. Serial No. 150,025.

To all whom it may concern Be it known that I, EDWARD JABs, a sub ject of the Emperor of Russia, residing at Elemwood Park, in the county of Coolcanci State of Illinois, have invented certain new and useful Improvements in Printing- Frames, of which the following is a specification.

My invention relates to. printing frames and has for its primary object the provision of improved means for accurately positioning a rubber stamp or similar device with respect to a card, sheet or other printing surface on which an impression is to be made.

A further object of the invention is the provision of an improved stamp guide which shall be yieldable horizontally to permit oscillation of the stamp during the printing action without causing blurring of the impression made upon the card.

A further object of my invention is the provision of guiding means. for the card being printed upon and guiding means for the stamp being used, all of which guiding means shall be adjustable as hereinafter described.

Further objects and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings.

In the drawings:

Figure 1 is a top plan view of my invention with a portion broken away to disclose parts below;

Fig. 2 is a front elevation of my invention;

Fig. 8 is a fragmentary side elevation; Fig. 4: is a section approximately on line 4L4cofFig.3; Q 7

Fig.5 is a fragmentary section. on line 55 of Fig. '1;-

Fig. 6' is a fragmentary section taken approximately on line 66.of Fig. 3.

Reference numeral 10 indicates a base provided with a platen 11 comprising preferably a thick layer of rubber such as is suitable for supporting a card or sheet upon which an impression is to be made from a rubber stamp. The base may be apertured to receive an inking pad 1 2 operated by means of a handle 13, the pad 12 fitting the base as a drawer fits a table. The platen 11 is preferably square and is contained within a square ridge 14 projecting upward from traverses the platen 11.

the base and having its upper-edge flush with the top of the platen. Spanning the platen and in contact with its upper surface is a card guide 15 provided atone end with finger 16 which} depends from the card guide'and overlies one reach of ridge 1 4:. A s milar finger 1? depends from the opposite end'ofcard guide 15 and overlies the opposide reach of ridge 1a. The preferred con struction of finger 17' is illustrated in- Fig. 6 where it will be seen that finger 17 is sligh-tly'spaced from ridge 14 and carries a spring 18 which, by means of a set screw 19 threaded into the finger 17 may be cambered into engagement with the outer surface of ridge '14 to secure card guide 15 in engagement with the platen. From this construction it will be seen that card guide 15 may be adjusted horizontally to any position between the front and back of platen 11. As seen in Fig. 5 card guide 15 is hollow and provided with a longitudinal slot 21. A card stop 22 is apertured as at 23 to receive the card guide 15 and carries a set screw 2 1 which traverses the slot 21 and is threaded into a traveling nut 25 fitting the 1 hollow portion of the card guide. The lower surfaces of card guide 15 and card stop lie flush with the upper surface of platen 11. Preferably the stop 22 lies at right angles to the forward surface of car/d'guide 15. Inasmuch as the card guide and the card stop are'bot'h adjustable horizontally it will be seen that a card may be positioned with any desired portion of its surface conveniently adjacent to the center of platen 11. Positioned directly over card guide 15 and having its forward surface normally alined therewith is a stamp guide 26 which The mounting for stamp guide 26 comprises a.post-27' positioned at one corner ofbase 10'and carrying an arm 28 which extends preferably to the median line of the platen 11 and at its inner end is T shaped,'the-T portion 29, Fig.

'3, of arm '28 being substantially coextensive f with stamp guide 2.6 and card guide'15. The mounting of arm 28' comprises a screw rod 31 swiveled in. the upper portion .of post 27 and depending into a vertical slot formed in the post, an arm carrier 32 adjusted and by employing wing nut 33 the carrier 32 may be locked in any vertical ad- 7 ustment.

The stamp guide 26 comprises preferably a channel shaped bar fitting about the upper and lower surfaces of the T portion 29 of arm 28 and slidably supported thereonv by a pair of studs 3%, coil springs 35 being interposed between the T and the stamp guide to force the ltamp guide normally to the forward limit of movement of studs 3%- preferably the studs are fixed in the stamp guide 26 and slidably engage the T 29.

The inner end of arm 28 is pierced to provide a bearing for an adjustable stop rod 36 which parallels the T portion 29 of arm 28 and lies rearwardly thereof in substantially the same horizontal plane. The stop rod is fixed in position in the arm 28 by means of a set screw 37 and carries a stamp stop 38 which is channeled to span stamp guide 26 and may be longitudinally adjusted with respect to the stamp guide. 7 A set screw 39 binds stamp stop 38 in any desired position longitudinally of stop rod 36. As illustrated best in Fig. 3, it will be seen that stamp guide 26 and stamp stop 38 are spaced above platen 11 substantially the same distance. In adjusting the machine for use the card stop 22 and stamp stop 38 are preferably positioned on opposite sides of the center of the arm 28 where it engages its T portion 29.

In the operation of my invention a card, illustrated in dotted lines at 4:1 in Fig. 1, is laid upon platen 11 with its left-hand end against card stop 22' and its rear edge against card guide 15 the stop and guide operating together to position the card with its edges parallel to stamp guide 26. It being desired to impress the type centrally on card d1 the arm 28 is adjusted forwardly or backwardly to so position stamp guide 26 that, when the side of the rubber stamp is against the stamp guide, the type will be central between the front and back edges of the card. Following this the stamp stop 38 is so adjusted transversely of the platen that a proper spacing of the type between the left and right edges of the positioned card is secured. As is well known, a rubber stamp generally requires oscillation of its handle while the type is'in engagement with the card in order that a well inked impression may be left. Were the-stamp guide 26 rigidly mounted upon T 29 oscillation of the stamp handle, which would normally be from top to bottom, viewing Fig. 1, that is from back to front, would cause a blurred impression to be left on the card by reason of the fact that the stamp itself would act as a lever, the power applied at the top of the handle being fulcrumed against the face of stamp guide 26 and the type being moved backwardly and forwardly with respect to the card. In order to prevent such lever action in the stamp I provide the yielding relation between stamp guide 26 and T 29 through the medium of the springs 85. By this means the rolling or oscillating of the rubber stamp merely moves the guide slightly toward and from the T leaving the type stationary with respect to the card 4:1 and the card stationary in its position against guide 15 and stop 22. The result is a clear impression made by the customary oscillating movement of the handle of'the stamp. If desired the stamp stop38 may be positioned to the left of arm 28, as shown in dotted lines at Fig. 1, and obviously card stop 22 may be positioned at any desired point throughout the length of card guide 15. V
