Description
The present invention relate~ t~ rubber stamp~ pre ferably of the self-inki~g type, which are u~ed for example in .
po8t offices and i~ particular to such ~tamps which are used for stamping dates, when cancelling postage ~tamps.
Postage ~tamps are normally cancelled in the post office by mean~ of automated e~uipment. However, where postage ~ -stamps are sold to collectors they are usually ~old either in blocks of four specimens, or else they are gummed to an enve- ~
lope. I~ thi~ ~ase, collectors will usually place consider- .-able value on the f~ct that the postage stamps have been ca~
celled by the post office on the first day upon which such postage s1:amps were issued. Generally speaking, such franking or cancelling of stamps on the date of is~ue has not been widely available at branch post offices. Branch post offices do not normally have the equipment for the applying of special cancell-ation stamps with the date of issue shown on the stamps, and therefore cannot normally provide this service and consequently it is usually only available at the head office.
Self-inking rubber stamps are available for the hand 2Q cancelling of StalllpB, and some of such hand operated ~tamps do incorporate sy~tem~ for showing the date, usually in the for~
of separate rubber belts with numerals and lettering.
~owever, collectors usually require not only a can-cellation of the ~tamp showing the date of is~ue, but they usually require a special cancellation stamp a~ well. This would mean therefore that branch post office~ would b~ required to carry a large number of hand aancelling self-inking rubber stamps each with a different stamp image for cancelling difer-ent i~sue~ of stamps and thi~ i8 clearly i~practicable.
~t i~ ther~fore a general ob~ective o th~ pre8ent _ ;'~ ' ' ' . , ~', : .
~1 03)'f~3~1L3 invention to provide a rubber 9tamp incorporating a series of interchangeable ~tamp mounting blocks or plates, each block carrying a dlfferent rubber die image, and each block pref~r-ably being provided with a recess for receiving interchangeable rubber indicia for showing the date.
More particularly, it i8 an objective of the invention to provide a ~elf-inking rubber stamp having the foregoing ad-vanftages in which the rubber indicia or plugs incorp~rate retain-ing means for securely locking thf~mf in position in the plate.
More particularly, it is an objective of the invention to provide a self-inking rubber stamp having the foregoing ad- .
vantagefs in which the removeable mounting plate incorpora1es a slotted opening for rec~iving the numeral plug~, and a recess or t well surrounding the slotted opening, in the back of the plat~
and in wh:ich the plug incorporates a generally T-shaped retain- ~-ing member fitting within the rece.~s, with the main body vf ~he E
plug extending through the slotted opening, thereby ~ecurely ~-retaining the plug in position in the plate.
The various features of novelty which characterize 20the invention are pointed out with particularity in thiof claims annexed to and forming a~part of this disclosure. For a better understanding of the invention, it~ operating advantage~f and specific objects attained by it~ use, reference should be had to thef accompanying drawings ~nd descriptive matter in which there is illustrated and de~icribed ~ preferred embodiment o I
the inv~ntion. ~:
IN THE DRAWINGS s Figure 1 is an exploded perspective illustration showing a typical self-i~king rubber stamp, provided with an 30int~rchang~able mounting plati3 ~ccording to the invention7 f~ .
j ~373~
Figure 2 i~ an upper perspec~ive illu~tration ~h~wing the mounting plate; -Figure 3 i f a section along the line~ 3-3 of Figure 2;
Figure 4 i~ a top plan view of a portion of the ~elf-. . ;.
inking rubber stamp, and, .
Figur~ 5 is a perspective illu~tration of the rubber f numeral plug.
Referring now to Figure 1, it will be understood that the present invention i~ illustrated a~ being applied to a sel~
inking rubber stamp. In such rubber stamps, an inking pad i9 carried in an upper portion of the stamp, and the rubber stamp or die is rotated and pressed against the inking pad, and is f then rotated back again and pressed downwardly against the paper .
or work piece. There are a variety of such types of self-inking stamps available, and the type illustrated in Figure 1 is merely exemplary of this class of rubber stamp, and is not to be regard~
ed as in any way limiting.
As shown in Figure 1, it will be seen that the form of self-inking stamp shown incorporates a generally rectangular housing or body 10, enclosing the inking pad 12. Two do~nwardly dep~ndent side frame m~mbers 14-14 are provided for ~arrying a moveable platen 16. The platen 16 i~ moveable between lower and upper positions, the lower position being illustrated in ~ :
Figure 1.
In its upper position it i~ reversed so a~ to face the :~
inking pad 12 and b~ pre~sed again~t the pad 12 for inki~g of ~:
the stamp.
In the nor~allself-inking rubber ~tamp, a rubber stamp or ~ie is glued to the exposed low~r face 18 of the platen 16.
The platen 16:i~ rotatably moun~ed on 8ui~abl~ rota~able. :`
3 - :
, ~. ' ~i3~73~
bearing means (not shown) ~o that it can be ~wung throuqh an arc of l80 so that it can either face downwardly a~ shown, or upwardLy against the inking pad 12. Rotation of the platen 16 is procured through a pair of sidle plate~ 20, movement of which is controlled by means of ~r~nnions 22 fastened on oppo-site 3ides of frame-~ 14. It will be under~tood that there are two such trunnions 22, on opposite sides of the side frames 14.
The side plates 20 are operated by means of the arm~ !
24 which are located on the exterior of the side frames 14, and may slide upwardly and downwardly with respect thereto. 1 ;
A rod 26 ex~ends between side plates 20 and extends outwardly therefrom through guide tracks 27 formed in side frames 14, and is connected at either end to arm~ 24. The tracks 27 are straight at each end and curved in the middle, thereby procuring the rotary action of ~he platen.
Extending upwardly from the housing lO is a cylin~
drical column 28, surmounted by a handle 30. The handle 30 i~
connected to the two side arms 24 for driving them downwardly.
The handle 30 is hollow and may be telescoped relative , 20 to the cylinder 28,and a compression spring located within the :
cylinder 2% and handle 30 provides for a return action ie. ex-tending the handle relative to the cylinder 28.
As mentioned, all of these features are essentially standard well known elements for this type Qf self-inking rubber stamp, and form no part of the invention. It is important to note however that ~,uch stamps are often u~ed quite abruptly by post office personnel so that the action of the platen 16 is extremely rapid ancl jerky. The platen will be normally resting in its inverted position against th9 inking!pad 12, and when ;~
the operator 81am~ the ~tamp dc~n on an envelope the platen l~
.
__ .. . .... . . ~ ... . . . . .
~L(11373~3 ` :
i~ driven downwardly and i~ then rotated 180 and then driven down a further distance until it hits the envelope after which the operator simply raises the handle 30 upwardly, and the ~pring action produce~ a reverse movement,almost equally abrupt.
As a result, the platen 16 is subject to very violent blows, and the rotary movement take~ place with great rapidity.
According to the practice ~f the invention therefore .
a plurality of replacea~le rigid mount.ing plate~ 40 are provided which are of essentially rectangular ~hape, and adapted to fit snugly within the two end wall~ 17 of the platen 16.
On the lower face of the plate 40 there is pro~ided a rubber die or impression 42 provided with any suitable relief image 44 of any desired design. Such a rubber die 42 will of course be adhesively bonded to the plate 40 in a well known manner. I
Within the relief image 44, there is provided a ~lotted ~:
opening 46 for receiving.indicia such as rubber plug members 54 providing a means for inserting the date of issue~ : I
Referring now to Figures 2 and 3, it will be 3een that the slotted opening 46 extends through the plate 40 and i~ loc- ` -ated within ~n enla~ged well or.rece~ 48 located in the rear .
surface o:E the plate 40.
In addition, a retaining pin 50 having an annular re-cess 52 extend~ from the rear ~urface of the plate 40 for re-leaseably securing the ~ame to the platen 16 in a manner to be 1.
described below. I
Figure 5 shows greatly enlarged the shape of the rubber date plug 54, having an upper T-shaped portion 56. The main body of the plug 54 extend~ through the slot 46, and the enlarged T- :
shaped portion 56 ~it~ within the well 48. In this way, the rubber plug~ S4 are securoly fastened in th~ r~ce~ 46 and carmot I
~ . .
become dislodged even during the violent and repetitive move-ment~ of the self~inking rubber stamp apparatu~.
Preferably the body 54 of the plug i equal in length to the depth o~ slot 46 and the thlckness o~ the stamp 42. The '.
T-shaped portion 56 is preferably o~E a thic~nes~ equal to or slightly great~r than the depth of well 48.
In order to retain plate 40 in position on the platen 16, a pin receiving soeket 58 is provided extending complotely through the platen 16. On the upper side of the platen 16, as shown in Figure 4, there i3 provided a locking bar 60 having a locking recess 62 therein adapted to fit snugly around the annular recess 52 on the pin 50.
An upstanding tongue 64 is provided at the free end of the bar 60 wh~reby it may be swung to and fro by a finger and thumb.
At the other end of the bar 60~ it is pivotally fast~
ened to the platen 16 by the bolt 66.- A spring 68 extends ; around the bolt 66, and engages a tan~ 70 on the bar 60 at one ; end, and the other end of the spring is secured a~ainst the post 72 on the platen 16. A stop member 74 is provided on the platen 16 to limit the forward ~winging mo~ement of the bar 60 t when the pin 50 has bsen withdrawn from the hole 5B. . ~ :
If desired, the top of the pin 50 could be beveled ~.
¦ or domed ~o as to provide an automatic camming action when the ` 1 plate 40 i~ being place~d in position, and the pin 50 i~ being placed in the hole 58., . ~ :
Sufficient plate~ 40 will be pro~ided with the sel~
inking rubber stamp unit ~o that a wide va~iety of different ~ancellation stamps mayibe made available to stamp collector~.
}n op~ratiQn, the po~t office employee will ~imply . - 6 - :
~, insert the correct numeral plug 54 in po~ition to show the right date, and the plate 40 will then be placed in position, by snapp ing the pin 50 into position ~o that the locking bar 60 and ~lot 62 engage in the groove 52 of the pin 50.
The self-inking rubber.~t~np can then be operated in the normal way as many times aY are required for cancelling 9tamps on that particular day. If, on the next day a different issue of stamp~ becomes available then a di~ferent plate 40 showing a different relief Lmage 44 will then be ~ubstituted, and the correct date will be inserted in such repl~cement plate 40, a~d the operator can then proceed as before.
Clearly, the invention will be applicable to variou~
different forms of self-inking rubber stamp~, with minor modi- I
fications pos ibly being necessary in the arrangement of the locking bar 60, or possibly being ~ubstituted by 80me other suitable form of locking ~ystem. I
In any event however throughout the operation, the ¦ ;
numeral plugs 54 are securely held in the plate 40, and cannot become dislodged no matter how violent the operation of the stamp its~lf. ~ ~
The plugs ~4 will show both numerals and numerals and months if de~ired and a complete set of such plugs 54 will be supplied to show allithe dates requixed. The T-shaped por-tions 56 are securely compressed between the platen 16 and the plate 40 and prevent the plugs 54 from being! driven back into 1 - the slot 46 or from becoming loose and falling out, during use.
Only three ~uch plug~ 54 ar~ shown but more or les~ may be u~ed depending on their width, preferably fllling the length and width o~ the slot 46. ~ ll Clearly, the invention wh1le belng de~cribed par~i-~ 7 --,, . .... ~,.. ~ , ...... . . .

cularly for use in post offic~s, for c~ncelling collectors date of issue stamps, is not to be confined solely to such use or purpose, and may have much wider application for a variety of other types of operation. For example, mail order houses operating under a number of different business names mlght well find the invention useful, or there may be many other business uses for the invention.
While the invention has been illustrated and described as applied to self-inking stamps it is equally applicable to simpler forms of date stamps in which a conventional separate inking pad is used to ink the stamp. In that case the platen of the stamp will of course be stationary and the plates will be releasably attachable to such platen in some suitable manner similar to that described above.
Having described what is believed to be the best mode by which the invention may be performed, it will be seen that the invention may be particularly defined as follows~
A rubber stamp comprising a platen, means for applying ;
said platen over a workpiece, a plurality of die support plates for carrying different rubber die images thereon on one side thereof, the other side being adapted to be placed on said platen, opening means in said platen, an engageable locking member on each said plate, oriented to pass through said opening -~means, and a movable locking catch on said platen movable into and out of engagement with a said locking member whereby to secure a selected one of said plates in position on said platen, and being readily releaseable for interchanging of said plates on said platen.
The invention further comprises a rubber stamp having the foregoing features and wherein said rubber stamp is of the ~tr~
~ (~3~3~3 self-inking type, and incorporates an inking pad, and mechanism for moving said platen alternately between the pad and ~aid workpiece.
The lnvention further comprises a rubber stamp having the foregoing features and including an opening in each said plate for reception of interchangeable indicia therein and, retaining means on said plate for retaining said indicia in position.
m e lnvention further comprises a rubber stamp having the foregoing features and including a slotted opening in each said plate, and a recess well formed in the back of each said plate in registration with said slotted opening, and having at least a width dimension greater than that of said slotted opening.
The invention further comprises a rubber stamp having ~he foregoing features and including opening means formed in each said plate for reception of indicia members therein, and including indicia members having a main body portion adapted to fit snugly across a dimension of said opening, whereby two or more such lndicia members may be arranged in said opening side by side, and including retaining means on said indicia members inter-engaging with said plate for retaining the same in position.
The invention further comprises a rubber stamp having the foregoing features and including a slotted opening having a length and breadth formed in each said plate, a recessed well formed in the other said side of said plate in registration with said slotted opening, a plurality of indicia members, each said member having a main body adapted to fit snugly across the width dimension of said slotted opening, whereby several such indicia members may be arranged side by side along the length of said opening, and a retaining portion forming part of each said indicia _ g _ . -- . ,.
I }, .:
~C~37;~L3 member adapted to be received in said well, and sandwiched between said well and said platen, when the plate is in position on the platen.
The foregoing is a description of a preferred embodiment of the invention which is given here by way of example only. The invention is not to be taken as limited to any of the specific features as described, but comprehends all such variations thereof as come within the scope of the appended claims.

cularly for use in post offic~s, for c~ncelling collectors date of issue stamps, is not to be confined solely to such use or purpose, and may have much wider application for a variety of other types of operation. For example, mail order houses operating under a number of different business names mlght well find the invention useful, or there may be many other business uses for the invention.
While the invention has been illustrated and described as applied to self-inking stamps it is equally applicable to simpler forms of date stamps in which a conventional separate inking pad is used to ink the stamp. In that case the platen of the stamp will of course be stationary and the plates will be releasably attachable to such platen in some suitable manner similar to that described above.
Having described what is believed to be the best mode by which the invention may be performed, it will be seen that the invention may be particularly defined as follows~
A rubber stamp comprising a platen, means for applying ;
said platen over a workpiece, a plurality of die support plates for carrying different rubber die images thereon on one side thereof, the other side being adapted to be placed on said platen, opening means in said platen, an engageable locking member on each said plate, oriented to pass through said opening -~means, and a movable locking catch on said platen movable into and out of engagement with a said locking member whereby to secure a selected one of said plates in position on said platen, and being readily releaseable for interchanging of said plates on said platen.
The invention further comprises a rubber stamp having the foregoing features and wherein said rubber stamp is of the ~tr~
~ (~3~3~3 self-inking type, and incorporates an inking pad, and mechanism for moving said platen alternately between the pad and ~aid workpiece.
The lnvention further comprises a rubber stamp having the foregoing features and including an opening in each said plate for reception of interchangeable indicia therein and, retaining means on said plate for retaining said indicia in position.
m e lnvention further comprises a rubber stamp having the foregoing features and including a slotted opening in each said plate, and a recess well formed in the back of each said plate in registration with said slotted opening, and having at least a width dimension greater than that of said slotted opening.
The invention further comprises a rubber stamp having ~he foregoing features and including opening means formed in each said plate for reception of indicia members therein, and including indicia members having a main body portion adapted to fit snugly across a dimension of said opening, whereby two or more such lndicia members may be arranged in said opening side by side, and including retaining means on said indicia members inter-engaging with said plate for retaining the same in position.
The invention further comprises a rubber stamp having the foregoing features and including a slotted opening having a length and breadth formed in each said plate, a recessed well formed in the other said side of said plate in registration with said slotted opening, a plurality of indicia members, each said member having a main body adapted to fit snugly across the width dimension of said slotted opening, whereby several such indicia members may be arranged side by side along the length of said opening, and a retaining portion forming part of each said indicia _ g _ . -- . ,.
