`To @ZZ whom it 7a4/cry concermj" i u Be it known that I, FRDRIG DE COPPET,A engineer, of Lausanne, Switzerland,have inl ventedcertain new and useful Improvements in AStamping Devices,

isa specification. v y y y The inventlon consists of certam new and of which the following ing devices as they are' more particularly used in post-oiiices for stamping by hand the ,let-

tersy or parcels. The said vrdevices must lbe capable of being made use o fy very quickly and at sametime of being applied very exactly upon the surface of the letter or parcel to be stamped; Furthermore, the well-known movable disks which vbear they letters and:

signs to befprinted and which .must be rotated once every day for changing the date to be stamped must, on the one hand, beea'sily adjusted in their desired relativeposition and,

onlthe other hand, bey prevented from leaving this said position during the stamping operation, although this said' operation imparts to the whole device very severe shocks.

The invention Icomprises a very strong but yet sufficiently yielding connection between stamping device, and the` invention further comprises a veryfsimple and positively oper# ative attachment for holding the movable.

In the several figures the same letters of reference referto the same parts. v

t is a handle of wood or other suitable material, in which is inserted asleeve the portion b of which is provided with suitable slots intended to havethe same working asa spring-clutch onf the rod o of the operative portion ofthe device.

The rod .c has a conical collar c', which bears the shocks of the apparatus during the stamping operation, and the saidv rod c is further provided with a collar 02 and with a Spherical enlargement or head c3.

The collar kis traversed by the inner end I l V of aspiral spring "d, fixed vthereto by means of apin e, and fthe external winding ofthe said spiral' spring d' is. firmly insertedv bev.tween a shoulder-f of the casing fand a shoulder g ofthe cover g,l screwed to the said casing f. The enlargement orhead c3' of the y `rod- 0 engages a suitable socket/t, inserted in the caslng f. Thissaid'casing fis'traversed and serving as an axis forthe 'rotating disks 76,? which bear lon their circumference the engraved letters and signs 7c', which are to be stamped. The said disks "le are providedv in' .the well-known -manner with 'corresponding series of,holes keach of these holes correJ l 'd spondingwith one of the letters or signs of the disk. E

Now for the purpose of adjusting the series of disks' ,7c in their desired relative position there is provided av U-formed pin m, having one of its arms pointed and the'other provided with aspherical enlargement m. The pointed arm of the pin m is intended to engage the I holes k2 of the 4disks le, and the spherical enlargement m is intendedito engage one endl of the tubular'axis a', both ends of whlch are construction of pin m, in combination with lsuitably beveled, as shown in Fig. 1. flhis" .the tubular axis and the holes k2, has for its object tosecure the pin in yits normal rest position, in which vit vholds the several disks 7e iny their adjusted position, whatever may be the slight deformations to which the said pin m' maybe submitted.` This is'illustr'ated by means of Figs. 4 and 5, fromwhich it may be yseen that if the-.pin m, the normal form of. which is shown in Fig. 1, happens to be wrenched either to the form shown in Fig. 4
