6 Claims.

'l'his invention relates to tape printing and cutting mechanism for use with a value printing machine, and more particularly to the issuing of individual printed stamps in selected predetermined quantities.

It is the principal object of the invention to provide a combination with driven tape printing and cutting mechanism, and manual release means for ed'ecting a cycle of operation; of actuator means which is adapted to cooperate with mechanical release means to produce a predetermined number of operations after manual release of the machine is effected, and thereby control the issuance of predetermined quantities or printed and cut stamps.

Another object is to provide selective control mechanism, whereby the mechanical release means is adapted to be variably set for controlling the issuance of variable quantities of printed ami cut stamps.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A preferred embodiment of the invention is illustrated in the accompanying drawings, wherein:

Fig. 1 is a front elevational view of a portion of a tape printing and cutting device including control mechanism for issuing predetermined quantities of printed and cut stamps;

Fig. 2 is an enlarged fragmentary plan view of the stamp issuing control mechanism taken su-bstantially along the lines 2-2 of Fig. 1;

Fig. 3 is an enlarged end view of a portion of the mechanism shown in Figs. 1 and 2, and is taken substantially along the lines 3 3 of Fig. 1;

Fig. 4 is a fragmentary detailed view showing the operation of advancing the printed tape po tion to a cutting position:

Fig. 5 is an enlarged detail operational view showing the stamp issuing control mechanism during a cycle of operation and with the mechanism set for the printing of a single stamp: and

Fig. 6 is a further detail operational view showing the control mechanism set for issuing a plurality of stamps, and showing an actuator member effecting a mechanical clutch release operation.

Referring to the drawings in detail, the machine comprises a printing drum It. having s Cl. lol-224) printing die il, Fig. 4. which is adapted to cooperate with a platen roller I2. in the printing of impressions upon tape T. Upon leaving the printing position, the tape is guided to a cutting member, generally indicated at I2, and by means of a tape feed shoe Il. is advanced suillciently to permit the printed portion thereof to pass beyond the cutting edges of the cutting member before cutting is effected, as best shown in Fig. 4. Cutting is effected in the usual manner by means of a cam actuated device, such as by a cam i5. which is adapted to. rock levers Il and iBa. tne latter being secured to the rotor portion ila of cutting member i8. After a cutting operation is completed, the tape is adapted to be retracted by means of a segment i1. which is driven in a counter-clockwise direction and cooperates with an opposing pressure roller il.

A power driven shaft I0 has a clutch 2i associated therewith. Said clutch is normally maintained in a non-driving position by means of a clutch trip lever 22. which lever is carried by a shaft til and is adapted to be rocked in a counterclockwise direction to eifect release of the clutch and initiate a cycle of operation. 'I'he means for rocking said trip lever 22 includes lever members 23 and 2l, fixed to a shaft 2l. the lever 23 being linked with the trip lever 22 at 22a. A manual control lever 2l. pivoted at 28. has one end 29 engaged beneath an extension 28 of lever 2l, which extension is normally urged against a stop 32 by means of a spring 82. W'hen therefore, a cycle of operation is to be eected. the operator will depress the handle portion ll of the manual lever 2l to rock the levers 2l and 2l in a counter-clockwise direction, thereby eifecting rocking of the trip lever 22, and the consequent release of the clutch 2i. At the end of one revolution of the clutch. the trip lever 22 will have returned to the position shown in Fig. l, under the impulse of spring 3l.

The above mechanism is of the conventional type generally found in metered mail machines and forms the operating medium with which the mechanism of the invention is combined.

Referring now to the mechanism of the invention, s device is provided for the issuing of variable quantities of printed stamps as desired. Said device comprises a ratchet wheel It, supported on a stub shaft ll. extending from a bracket I0, and has axially joined therewith. a disc I6. A pawl 21 is supported on a pin I8. projecting from a lever 39, which lever is pivotally mounted at the end of the stub shaft ll. Said pawl 31 is also urged toward the ratchet teeth of the ratchet wheel by means of spring 4I.

A mechanical or automatic clutch release is provided. which includes a rocker lever 42. having a projecting portion 44. Said rocker lever is pivotally mounted upon a stud 42 extending from the bracket 4B. A pin 4i. extending from one face of the rocker lever 42, is normally urged toward the peripheral surface of the disc 36 and will normally engage a notch 4l therein. Said rocker lever 42 is also connected with the manually actuated lever 24 by means of a link 41. Hence, when the lever 24 is rock through the manipulation of the lever 21, the rocker lever 42 is also rocked to effect removal of the pin 45 from engagement with the notch 46, and to further effeet movement of the projection 44 of the rocker member 42. into the path of a driven actuator member 48.

The actuator member 43 is shaft i9, and has one projecting nnger portion 4l. Said nger 49 is adapted to cooperate with the projecting end 44 of the rocker lever 42 to effect the rocking thereof. and the consequent tripping of the clutch 2l, for effecting a subsequent cycie of operation. Another portion 6I of said actuator member 4l is connected with the pawl supporting lever 30, by means oi a link 52. Hence, when the actuator member 48 is rotated, the pawl supporting lever 39 will be rocked to effect a reciprocating movement of the pawl l1.

A variable feed of the ratchet wheel 34 is provided by varying the position of engagement of the ratchet teeth by the pawl I1. This is accomplished by shielding the pawl from engagement with the teeth of the ratchet wheel during a portion of the driving stroke of the pawl. Said shielding is effected by means of a lever 63 pivotally supported upon the stub shaft 35, and having a lower segmental end portion 54 thereof arranged with an arcuate edge 54a extending beyond the outer edges of the ratchet teeth of the ratchet wheel 24. -A handle 55 projects upwardly from the lever 53 and has a pin 56 projecting from one face thereof. By varying the position of the lever 53, the pawl 31 is. adapted to be controlled so that it will engage and advance the ratchet wheel the distance of one. two, or four teeth. With forty-eight teeth in the ratchet wheel, provision is thus made for issuing forty-eight, twenty-four or twelve stamps respectively.

The locking of the shielding portion of the lever 53 in any adjusted position. is provided by means of a notched lever 51. Said lever 61 is mounted upon a stud 58, carried by the bracket 40, and 4has notches 59 spaced along an upper arcuate edge thereof. The lower left end 60 of said lever 51 bears against a at cam portion 6| of the rocker lever 42. When the lever 42 is rocked as a result of the engagement of the actuator finger 49 with projection 44, the notched lever 51 will be rocked upwardly by the cam portion BI to ei'fect engagement of the pin 58 with one of the notches 59.

When the handle t5 is set in the extreme left position, opposite the notch 58a, as indicated in Fig. 5, the arcuate edge 54a of the shield 54 will occupy a position relative to the ratchet teeth which will prevent the pawl from moving into active engagement therewith during the operating stroke thereof. Referring to Fig. l, where the parts are shown in a home position, the pawl 31 is shown positioned the distance of sevxed to the drive eral teeth from the right end of the shield. Referring now to Fig. 5, wherein the actuator member 4B has moved 180 to advance the pawl a. full stroke forward, it will be seen that the tooth engaging edge of the pawl has advanced to the end of the shield, but has not moved into engagement with a ratchet tooth. Inasmuch as the pawl has not engaged and moved the ratchet wheel 34, no motion will be imparted to the disc 3B. Therefore, the pin 45 on rocker lever 42. will re-engage the notch 46 in the disc 34, before a cycle of machine operation is completed. A single stamp is thus issued after each operation of the manually controlled lever 21.

When the handle 65 is set opposite the second notch indicated at 59h, the arcuate edge 54a of the shield 54 will become positioned two teeth to the left of the position shown in Fig. l. During the cycle of operation the pawl 31 will move beyond the right end of the shield into engagement with the ratchet teeth, and will advance the ratchet wheel the distance of one tooth. It is to be noted that the movement of the pawl down the ramp portion 54h of the shield S4, will not transmit movement to the ratchet wheel 34.

When the ratchet wheel is moved, the disc 36 will move a like distance and the notch 4B will move beyond the path of the pin 46. The projecting portion 44 of the rocker lever 42 is thus maintained in the path of the actuator linger 48, and will be rocked when engaged by said linger. Rocking of the rocker lever 42 will effect release of the clutch 2| for another cycle of operation, which action will be repeated after each cycle until the disc 3B has moved through 360 to its home position. When in said home position, the pin 45 will re-engage the notch 46. and the projection 44 will be withdrawn from the path of the actuator finger 49. Also, when the disc 3B has moved, setting lever 53 is maintained in a locked position until the required number of stamps have issued.

When the handle 55 is set opposite the notch 59e, the pawl 31, during its normal stroke will move two teeth beyond the end of the shield 54, thus advancing the ratchet wheel the distance of two teeth. With forty-eight teeth in the ratchet wheel, the two tooth advance will iue twenty-four stamps during one revolution of said ratchet wheel.

In a like manner when the handle 55 is advanced to the last notch 59d, the pawl 31 will advance the ratchet wheel the distance of four teeth during each forward stroke thereof. It will be noted that the notch 59d is twice the distance from notch 59e, as 59o is from 59h, hence the advance of the ratchet wheel is proportionately greater. Twelve stamps are thus issued during each cycle when the handle is set to the last notch position.
