STAMPING MEoHANisM.

To all whom it may concern:

Be it known that I, FREDERICK WILKIN- soN, a subject of His Majesty the King of England, residingv at Glazenwood, near Braintree, in the county ofEsseX, Kingdom of England, have invented certain new and useful Improvements in Stamping Mechanism, of which the following is a specificati'on. a 7' This invention relates to improvements in coin-freed machines'of the kind adapted for stamping the impression of an oflicial mark, sealor the like upon letters, post-cards and the like, so that the sender may use such machine which is arranged in connection with'a post-box or a receptacle, for effecting .the die or stamping device is arranged in prepaymentof the usual postal rate in lieu of ordinary adhesive stamps.

It has for one of its objects to provide a more simple and effective machine wherein one of a pair of pressure rolls between which the letter, card or the like is passed and stamped before dropping into the receptacle or letter-box. T

. Another object is'to provide such a machine with an improvedcoin-freed mechanism which will insure that the feed rolls cannot be turned to take a letter until a coin has been'inserted.

I will now describe the preferred manner of carrying out my invention with reference to the accompanying drawings, inwhich:

Figure 1 shows a front elevation of a box or casing adapted to serve as a pillar boXor receptacle for posted letters, and having my stamping machine fitted on the inside of the door thereof. Fig. 2 isvan enlarged elevational view of the machine'and the reverse side of the door; Fig. 3 is a side elevation of same; Fig. 4 is a like view, with the side .of the bed plate or frame removed; Fig. 5

isasectional elevation about the line AA .of Fig. 1, and Figs. 6 to 12 are detail views other to indicate their respective positions when assembled. Thus, Figs. 6-8 are views, each partly in section, of the frame or base;

Fig. 9 is aplan view of the main portion of the coin cylinder; Fig. 10 is an end view of Fig. 9, Fig. 11 shows the smaller portion or half of the cylinder removed from the other portion but ofcourse reversed to show the formation ofthe inner surface thereof.

0Z and the'operating handle 6 through the *medium. of the worm wheel 7 mounted on rotates in-front ,ofthe door Z of the casing rm which is formed 'to contain, the

machine and, if desired, to collect. the letters, post-cards and the like. when. they:

have been stamped by said machine. The

door or front Z isffurnished with suitable, face plates n, 0 in which the coin'slot p and the letter opening q-terminate. A die 1- with a curved or straight surface is mounted-in the roll a in a diametrical boretherein or therethrough, and it may be arranged that" it will .;-normally contact with a springj or resilient bed in the" A suitable device for inking the die con-f.

sists of. a rubber-covered contact roller 8 andan ink roller 9 mounted in a pivoted frame which is adjustable by means of nuts on the screw-threaded post 10. I

The die-carrying roll a is preferably providedwith a plurality of other dies or marks 8 forming a pattern which would be registered on the surface of the envelop, postcard or the like, thereby enabling the exact position of the die proper tobe determined in relation thereto for the purpose of detecting fraud. l

The coin freed mechanism shown particularly in Figs. 5 to 13 comprises a Totating two-part cylinder t-t geared and moving with the rolls by means of the wheels u,"vvo, and having a coin slot or aperture 40 therein normally adapted to regliter mally before a coin is inserted into the mechanism, the cylinder is held'from 1'0 tation by means of the member as controlled by a light spring 00 which member has a projecting portion 3 adapted to engage teeth or notches z in the bearing ring 1, at one side of the coin cylinder, should the latter be slightly turned. A coin inserted into the slot 7) falls by gravity into the slot to of the cylinder, engages between the face t of the part t of the cylinder and the member 00, and presses the latter back as shown in Fig. 13, thus when the handle 6 is operated the coin engaging with and holding the member a" back against its spring prevents the projecting g thereon entering the notches 2,- thus the cylinder and the rolls may be rotated.

The coin is ejected from the slot w, upon the rotation of the coin cylinder, by means of the lever 2, the end 3 of which engages in the cam groove 4 in the frame at one end of the coin cylinder. 7

The spindle of the coin cylinder is pro- I vided with an integrating mechanism 5 for recording the number of operations. In some cases, means may be provided for successively numbering the letters or the like passed through the stamping mechanism, and as the coins are deposited in order in a chute 6 and collector 11, even if a metal disk or counterfeit coin were inserted the sender could be traced by the number of the letter and the position or order of the coin in the collector.

The means shown for operating the integrating mechanism 5 consists of a disk 12 mounted on one end of the spindle 13 of the coin cylinder and having a cam groove 1% in-which a pin 15 fixed on the lever 16 travels, the movements of the lever being transmitted to the device 5 by links 17.

A spring 7 or a weight is provided to assist the return of the coin-cylinder to its initial position after each operation.

If desired the feed or stamping rolls may be arranged over a suitable letter receptacle other than the bottom of the casing m, so that the letters, cards or the like will fall from between said rolls, after they have been stamped, into the receptacle.

The door Z is provided with suitable direction plates or tablets for the information of the public, the plates 18 giving directions as to the insertion of the letters, post-cards and the like into the slot (1 and the opera tion of the handle 6, and the plate 19 the coin to be used, and if desired the disk in may also bear directions as to the operation of the handle. If wide letters have to be stamped the hinged flap 21 has to be raised away from the slot 9. In the example shown the handle 6 has to be turned through two complete revolutions for the proper workof the stamping mechanism, and for this purpose the series of rotating and coacting blocks or segments are provided on the spindle d to rotate therewith in known manner.

One end of the roll Z) is furnished with ratchet teeth 22, and when a letter or the like is passing between the two rolls a slight movement of the roll a upward, against the compression of adjustable springs 23 contained in the cups 24 and bearing upon the sliding bearing blocks 25, allows the pivoted trip or motion multiplying lever 26 to swing upward by medium of the leaf spring 27, which lever frees the adjustable screw 28 mounted in an arm on the pivoted pawl 29 and allows the letter to drop into said teeth 22, thus preventing backward rotation of the rolls, once they have started to rotate, and withdrawal of the letter. The springs 23 and 27 are of such co-acting and opposing strengths that normally the pawl 29 is held just away from the teeth 22 as shown in Fig. 5.

It will be seen from the drawings that the coin collector 11 is detachably attached to the end of the chute 6 by pins and bayonet slots, and the lower end of said collector is preferably provided with means for securing it against tampering and fraudulent removal of the coins, by a padlock or the like, or if desired the coins may be arranged vto drop into a boX or other form of receptacle under the chute.

Now referring to Figs. 5 to 13, it will be seen that the coin cylinder is split into two parts or halves t, t which are formed and recessed to provide the coin slot 20 and to contain the spring-pressed ratchet member :0 and the coin-ejecting lever 2, and the two halves are held together by means of the locking pin 30 Fig. 5 which passes through oppositely disposed holes in the flanges 31 of the part 6 and the hole 32 in the part t.

Modifications may be made in the general construction of the machine so long as they conform to the claims and to the principles of the operations of the different parts described.

Rubber pads or buffers 33 are provided against which the segments 20 abut to minimize the shocks due to the operations of the machine and the tension of the spring 0.
