AUTOMATIC STAME-DEL-IVERY MACHINE.

Application filed December 6, 1920.

T 0 ctZZ to how. it may concern Be it known that I, TTERMANN TEUN, residing. at Essen-on-the-Ruhr, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Automatic Stamp-Delivery Machines (for which I have filed an application in Germany July 1, 1919), 01 which the following is a specification.

The subject matter of the invention is an automatic stamp delivery machine which is capable as required, either of delivering an unmoistened stamp or providing a thing to be posted with a stamp.

On the drawing an example of construction of the subject matter of the invention is shown. On this drawing:

Fig. 1 is a longitudinal section of the device, some parts being omitted,

Fig. 2 is the same section as Fig. 1 with a different position of the individual parts,

Fig. 3 a plan view on a larger scale of a part of the device,

.Fig. 4; is a part of Fig. 1 on a larger scale,

Fig. 5 is a side view of Fig. 4, partly in section and with certain parts omitted, and

Fig. 6 is a part of Fig. 4 with certain elements in different positions.

In a casing A a shatit B is mounted which can only be turned clockhandwise after the insertion of a specific coin in a slot provided for that purpose, the turning being effected by a motor, which is not shown. On the shaft 13 there is mounted a disc C, provided with two curved grooves o and 0 A. bolt 65 engages in the groove 0 the said bolt being fixed to a bar D, pivoting about a fixed pin 0: The groove 0 is so designed that when the disc C is in the angular position shown on Fig. 1 a rotation of the shaft- B clockhandwise causes the bar D first to pivot in the opposite direction until the highest pointof the bolt (Z is reached and afterwards to return to its original position. On the free end or" the bar D a connecting rod E is joined to which one end of a two-armed lever F is connected by pin joint. The two armed lever Fis pivotally mounted on a fixed pin o The other end of the lever F is shaped as a fork f and embraces a bolt which is mounted on a spindle G carrying a stop collar 9 The spindle G is guided in a tube I-l slidable in a stationary cylin- Specification of Letters Patent.

der a and carrying on its lower end the tear-ollpunch 71. In the path ofthe tear-off punch It lies the end, shaped like a hook t of a clamp i which is mounted on a stirrup J so that it can rotate about an axis ly-v ing in the plane of the drawing and is controlled by the gripper (not shown). The stirrup J can slide on a fixed rod of against the action of a spring i A little way above the hook i a strip of stamps a ends, being coiled up on a rotatable stamp, roll a. The stamp-strip a can be seized by a twopart gripper 7, 8, and be drawn into the path of the tear-01f punch M. The two parts of the gripper 7, 8, are mounted on the free ends of two levers 12, which swing on two co-axial pins and are acted upon by two springs 11. The gripper is also connected as will now be described with the lever F. On one end of the bolt 9 engaged by the fork P, (Fig. 1), is mounted a down-.

wardly d' ected controlling rod 2, (Fig. 5), which carries a roller 1 on its lower end. By means of said roller, rod 2 bears on one arm of an oscillatory two-armed lever 8, acted upon by a spring 21 and provided with a nose 24. The other arm of the lever 3 is provided with a set-screw 5, which bears against a lug of a two-armed lever, 6, also pivotally mounted and connectedto lever 3 by a spring 1, the ends of which engage the arm of lever 33, carrying set-screw 5 and one arm of lever 6. In the free end of the other arm of lever 6 is mounted a bolt 17, which is provided with a recess 23, of the shape shown particularly in Fig. 6. To the bolt 17 are pivoted two links 9, the free ends of which are pivoted to the two parts of the gripper 7, 8. On the pivot pin of the gripper is also mounted to swing a latch member 15, in which is cut a groove 22, of the shape shown in the drawing, to receive the bolt 17, and which is connected to said bolt by a spring 16. The groove 22is provided with a nose 25. On the frame A are also mounted two fixed abutments 13 and 19, and a roller 20, which co-acts with thelatch member 15 and the action of which will be later described. Below the stamp strip a a water pot a is provided being shut off by a stopper a which sucks up the moisture. Against the stopper a there lies a wetting roller 76 which is rotarily mounted on one end of a two-arm lever 70 The two-arm lever K. pivoting under friction around a fixed pin a and lies with itsfree end on a pin [a under the action of a spring (not shown), the said pin in being mounted on the lever K. One arm, 70 of the lever K projects into the path of two pins g and g which are mounted, on a connecting rod G fixed to the bolt 9 The lower pin 9 in the position shown in Fig. 1 of the different parts rests below against the arm 70'. The upper pin is distant from the lower one by an amount which is equal to the distance oi the stop collar g from the front face 01" the tube H, increased by the distance of the lower boui'iding surface of the tear-off punch. h from the inoistening roller 0 To the arm 01 the lever K a bolt is is providedwhich engages in a groove m of a guide rod M. The latter is pinjointed to one arm of a ti'vo-arm lever N which is mounted on a shaft N mountedin the casing A. On this shaft a comb-shaped feeler N is also inounted. To the second arm 01: the lever ii a tierod P is'pinjointed, the otherend 01"- which is jointed to a lever Q. This latter is pivotally mounted on the pin a Besides this there is mounted pivotally on the pin a a two arin lever B against theone arm of which, connected with the lever Q by a spring 9 a shoulder g of the lever Q, lies. The other arm of the lever B carries a bolt r which ei'igages in the curved groove 0 on the disc C. The groove 0 is so designed that in the angular position of the disc C, shown in Fig. 1, a rotationoilf the'disc C clookhandwise causes the lever R to pivot in they opposite direction up to the highest position of the bolt 14 and afterwards to return toits original position. Finally on the pin a a toothed segment T is pivotally mounted. This toothed segment T carries a pin-t? which projects into the path of the lever Qand is distant. from the lat ter by a given amount inthe position of the parts shown by Fig. 1.

' ment T lies, under the action of a spring i againsta fixed pin a. It meshes with a pinion V which is coupled with a second toothed segment V The latter meshes with I a rack e0 provided on a slideable table W.

The edge of the table W' which is on the left side of the drawing lies opposite the feeler N and, like the latter, is of coinb design inv I the comb slots in the table. Below the table TV is a'funnel a lying oppositeto the tear oft punchh i If it is required to'take from the above de-" vice an unmoistened stamp, a coin corre- The toothed segput into the slot provided. The shaft B and with it the disc 0 then rotate clockhandwise and, through theagency of the lever D, the

coniplished as follows: The lowering of the rod 2 has swung the lever 8 in anti-clockwise direction against the pressure of spring 21, by means of the roller 1. In this angular movement of lever '3, lever 6, connected therewith by spring l, takes part, so that italso turns about its axis in anti-clockwise direction. In the beginning of the swinging movement of lever 6, pin 17 moves through the narrower part of groove 22-oflatch member 15, and the gripper '7, 8, is accord ingly closed by the links 9, and takes hold oi the stamp-strip a whereupon the levers 12 take part in the movement of the lever 6 against the pressure of the springs llQi/Vhen, in this movement, the lever 6 strikes against the lug 13, the stamp-strip has been drawn out for the length oi one stamp. After the engagement ot lever 6 against lug 13, lever 3 turns alone in anti-clockwise direction and engages by its lug 24 against one of the levers 1'2 and turns it in the same direction. The other lever 12 takes part in this move- D'IQHt and therefore the gripper '7, 8, opens again and releases the stamp-strip. During the opening of the gripper, thelatch member 15 moves in the direction of the arrow at, relatively to the pin 17, held stationary by the high}, until the nose% has moved out of the .cess of the pin 17. As soon as this has taken place, said member 15 moves into the latching position shown in Fig. 6, under the influence of spring 16, in which said member is prevented from moving inthe opposite direction to the "arrow 03, whereby they gsipper Z, 8, is prevented from closing too soon. W hen, in the further operation,

the rod 2 is a ain raised, all theparts,controlliiig the gripper 7, 8, return to their orig nal positions shown in F 1g. 4, under the influence of the springs 21,11 and 1, and the roller 220, n which positions the levers 12 bear onthe lugs 19 and the gripper 7, 8, is ready to again seize the end of the stampstrip During these movements, owing to the guidingo l the bolt r in the groove 0 the lever P has been rotated anticlockhandwise. Under the action of the spring 9 the lever Q follows the rotation and transmits the latter, but in the opposite direction, through the draw-rod. P to the lever N and conseeuently to the feeler N 'The' latter pivots through the comb-slots in the table W. On the rotation of the lever N the guide rod M slides, and after a short shift the left stop face of the slot m comes to lie against the bolt The lever it; is now rotated anticlockhandwise so that the moistening roller Z2 moves out of the path of the tear-off punch ill. The ratios of gearing are so contrived that this takes place before the tear-off punch has torn a stamp off. Before this latter takes place meanwhile the table IV has also been shifted tothe right into the position shown by Fig. 2. This is brought about by the fact that in its rotation the lever Q comes to lie against the pin t and thereupon carries along with it the toothed segment T. The rotation of the latter brings about, through the a ency of the pinion V, the toothed segment 1 and the rack w a shifting movement of the table W to the right. After the tearing off of the stamp the clamp i swings out and releases the stamp so that the latter falls into the funnel a and can be taken out (Fig. 2). On further rotation of the disc C the individual parts return again to their original position, namely, the toothed segment T and through it the table W, owing to the action of the spring t and the stirrup J under the action of the spring 71 If the thing to be posted, for instance the letter W is to be provided with a stamp, the letter is thrust through the slot provided for that purpose onto the table W in such a way that it overlies its comb-slots. After the coin has been inserted there take place in the first instance the same movements as when taking out an unwetted stamp. But the feeler N is now unable to swing through the comb-slots of the table W because it strikes against the letter Vi. From the moment of its so striking (dotted line position on Fig. 1) the feeler l 2 and also the parts connected with it N M, P, Q, remain at rest, while the lever R swings onwards under the action of the spring 9 The arrangement is such, however, that the feeler N strikes against the letter W shortly before the lever Q would come to lie against the pin 6 and the left stop face of the slot m against the bolt is. Consequently the table W also remains at rest and the lever K is. not influenced by the feeler N On the descent of the tear-off punch 72, finally the pin 9 comes to lie against the arm k of the lever K. According to what has been explained above this takes place when. the stamp held between the hook i of the clamp i and the tear-off punch 72, and which has already been detached from the stamp strip a comes to lie against the moistening roller 70 On further descent of the tear-off punch h the lever K is rotated. anticlockhandwise by the pin 9 the pin is sliding in the groove m In the rotation of the lever K the m istening roller k passes under the stamp. and wets it. The moisten ing roller 70 finally passes out of the path of the tear-off punch when it approaches the letter Shortly aefore the tear-off punch 72. impinges on the letter W the clamp i swings out and releases the stamp which is now firmly pressed by the tear-off punch 72, on to the letter. Ilereupon the several parts go back into their original position and the letter can again be taken out of the machine provided with the desired stamp.
