MECHANISM FOR THE STAMPING OF LETTERS, POST-CARDS, AND THE Application filed July so, 1912. Serial No. 712,305.

To all whom itmay concern Be it knownthat I, FREDERICK WILKIN- soN, a subject of His Majesty the King of England, residing( at Glazenwood; near Braintree, in the county of Essex, Kingdom of England, have invented certain new and I useful Improvements in Mechanism for the Stamping of Letters, Post-Cards, and the like, of which the following is a specification. g

This invention. relates, to improvements in mechanism for the stamping of letters, postcards and the like so that the sender may use such means effecting prepayment of the postal rate in lieu of, ordinary adhesive stamps. I

It has for its object to provide a more simple and efiicient device of this kind wherein the die. stamping mechanism and the-coin slot or slots can be arranged in one or both of a pair .of pressure rolls through which the letter, card or the like is passed into the receptacle or letter box.

The invention is illustrated in the accompanying drawings in which Figure l is a sectional side elevation of the die stamping and the counter roll detached from their case; Fig, 2 is a plan view thereof; Figs. 3 and 4 are sectional views taken in planes at right angles to each other through the counter roll; Figs. 5 and 6 are two plan viewsof the die stamping roll with the die carrying portions removed; Fig. 7 is a reversed plan view of the removed die carrying portion; Fig. 8 is a section through the said roll and die; and Fig. 9 is a side elevation showing the coin ejecting cam on the side of one of the journals.

, In one way of carrying out my invention I provide spring pressed die and counter rolls a b respectively which are adapted to be rotated by spur gearing from a suitable spindle 0 and operating handle d. A die or plunger 6 with a curved or straight surface is mounted in one of the rolls a in a coin slot 7 is made the die-carrying roller Specification of Letters Patent. 7 Patented 18,'1915. l

a for the reception of a suitable "coin'lg 1" l which, when inserted therein, will form an abutment for the. die 0 and insure itsbeing pressed outwardlyfagainst the surfacejaof any letter or card afterward inserted. Upon the further rotation of the rolls the coin g would be freed as soon as pressure was removed from the die 6 and itwould' then be ejected or drop out into a suitable coin receptacle not shown. 1

- The feed or stampingrolls a I) would be arranged over the letter receptacle so thatthe letters, cards or the like will fall therefrom when stamped. In order to. prevent damage to the. die e or to the letters and also to enable a fair I lmpression of the die to be made onfen- V vel'ops containing folded paper in case the unevenness should fall directly under the die I provide a resilient abutment on the counter roll. This is comprised of a number of square headed studs 2' which are arranged in a. removable section b of the roll 6 and which at their inner ends bear against rubber packing strips 7' as shown in Figs. 3 and 4. I

Forconvenience of construction'the die 6 is also mounted in a' removable portion a of the roll a and; when assembled it is kept in place by a set screw k which worksin a slot Z therein, with the springh. The

insertion of a, coin prevents the die from being pressed in by, the letter which thereby receives its impression. To insure the ejection of the coin after the letter has been turned. through I provide aleverm which engages a cam n on one of thel'journ'a'ls o of the machine and positively expels it from its slot 7, and in order to prevent its dropping out before the letter has been stamped or before'the said cam slot is over the coin receptacle I also provide a sliding spring controlled pin'p which engages a cam surface g on. the'opposite journal 7' and is extended thereby till theroll has been rotated through the required angle. I

An intermittently engaging spring pressed ward rotation of the rolls and the withdrawal of a letterwhen once inserted be 1 tween the rolls and its movements maybe controlled in any convenient manner by the backward and forward movement of the counter roll Z) which when spaced from the die roll a by the insertion of a letter against the tension of the spring pressed bearing blocks 0 allows the said pawl to engage the teeth on the end of the roll a. This movement is effected by means of an intermediate member or link 22 which bears on the upper extension of the pawl s and also on the shaft of the roll 7). When however the rolls are again in contact the pawl is withdrawn or lifted and a weighted chain t running over a sprocket wheel a causes the rolls to be returned to their initial position ready for the reception of the next letter. This can also be accomplished by means of a coiled spring on the spindle ofthe coin or other roller.

What I claim and desire to secure by Let ters Patent of the United States is 1. Means for stamping letters, post cards and the like comprising a pair offeed rolls between which the letters or the like are fed, a die slidably mounted in one of the rolls, a resilient surface on the'other roll adapted to register with the die upon rotation of the rolls, the roll which carries the die having a slot forthe reception of a coin adapted to engage the die and hold it out of the slot and thereby cause the die to make an impression upon the letter or the like when the die is brought into registration with said resilient surface.

2. Means for stamping letters, post cards and the like comprising a pair of feed rolls between which the letters or the like are fed, a die slidably mounted inone of the rolls, a resilient surface on the other roll adapted to register with the die upon rotation of the rolls, the roll which carries the die having a slot for the reception of a coin adapted to engage the die and hold it out of the slot and thereby cause the die to make an impression upon the letter or the like when the die is brought into registration with said resilient surface, and meansfor ejecting the coin after said impression has been made.

3. Means for stamping letters, post cards and the like comprising a pair of feed rolls between which the letters or the like are fed, a die slidably mounted in one of the rolls, a resilient surface on the other roll adapted to register'with the die upon rotation of the rolls, the roll which carries the die having a slot for'the reception of a coin adapted to engage the die and hold it out of the slot and thereby cause the die to make an impression upon the letter or the like'when the die is brought into registration with said resilient surface, and means for returning the rolls to their initial position after each operation.

4. A coin-controlled apparatus including a roll provided with an open-ended coin slot,

a cam operated lever to prevent movement of the coin through one end of the slot and to eject the coin from the other end of the slot at a predetermined time, and a spring pressed element adapted to be projected into the slot to prevent accidental displacement of the coin through the opposite end of the slot until said predetermined time, and means to project and hold projected the spring pressed element until said predetermined time whereupon said spring pressed element is released to permit ejection' of the coin through the cylinder by said cam operated lever.

5. In a coin controlled apparatus, a roll provided with an open ended coin slot, automatically operating means cooperating with the roll to prevent passage of the coin through one end of the slot 'and operable to eject the coin from the roll through the opposite end of the 'slotat apredetermined time, and automatically operating means connected to the roll and projecting into said slot to prevent accidental displacement of the coin through said opposite end of the slot until said predetermined time.

6. Means for stamping letters, post cards and the like comprising a pair of feed rolls adapted to rotate in opposite directions and in close proximity to each other, a die slidable in one of the rolls, the roll which carries the die havinga slot for the reception of a coin adapted to engage the die and hold the die out of said slot so that the die may effect an impression upon the letter or the like fed between the rolls.

7. Means for stamping letters, post cards andthe like comprising a pair of feed rolls arranged to rotate in close proximity to each other to feed letters and the like between and through thesam'e', a resilient surface carried by one of the rolls, anda coin controlled die carried by the other roll adapted to register with said resilient surface to effect an impression on the letters and the like as they are fed between the rolls.

8. Means for stamping letters, post cards and the like comprising a pair of feed rolls arranged to rotate close proximity to each other to feed letters and the like between and through the same, a resilient surface carried by one of the rolls, and a coin controlled *die carried by the other roll adapted to register with said resilient surface to effect an impression on the letters and the like as they are fed between the rolls, means to eject the coin, .an'd meansto prevent backward movement of the rolls.

9'. Means for stamping letters, post cards or the like comprising'a pair of feed rolls, a yielding surface carried by one of the rolls, a slidabledie' carried by the other roll for registration'with the yieldable surface of the companion roll during rotation of the rolls, the roll whichc'arriesthe die having a same out of said slot so as to effect an imslot therein for the reception of a coin which In testimony whereof I afii x my signature is adapted to engage the die and hold the in presence of two Witnesses.
