IMPROVEMENT IN -sTAMP-CANci-:Lsns- Specification forming part of LettersjPatent No. 121,765,
" .lunel 1l, 1878; application Jled May 27. 187.8r
.To all-whom it may concern: 'Be it Vknown that DANIEL Massachusetts, inventeda'Dev'ice for Can-- celing 'Postage or other Stamps; and that -the following speciiication is a full, clear, and
exact'description of the invention, sufficient to enable those lskilled in the art to-practice it..
The invention relates to a new device for .i
canceling postage or other stamps by brand- .ing or burning them.
The novelty of the inventiony consists in the application of electricity to La ,properly-con-v structed die or stamp, whereby the die, which may be a coil'of platinum wire, is heated'sufiiciently to char` or burn [the surface ofthe postage-stamp, and thereby cancel it so' effectually .as lto prevent its reuse. For this purpose, the. stampuor canceler handle is made with an insulated `o1" non-conducting button, having a stem or spindle-'extending into -an insulated handle, or a handle niadeofl non-conducting material, the lhandle containing a spring for forcing the button outward.
l,Across they face o f the. button extends a wire, theends of which connect with metallic conductors extending through the button.
Through the handle extendtwo wires for connection with the two poles 'of a battery', these wires passing through to the bottom of the handle, so that connection is made between them by their connection with the two conductors when the handle and button are brought together, and the connection of the two conductors by the wire running across the face of the button. When the connection is thus made, the wire is heated by the electric current, and by contact with a stamp will burn a mark across its face.
In the accompanying drawing, Figure l is a side elevation of a stamp-cancelar embodying the invention. Fig. 2 is a central sectional view in elevation of the same. Fig. 3 is a bottom-plan view of they canceler.
A denotes the handle, made of ebony or tether hard wood, or of glass orother suitable electric non-conductor.
B is the button or head, which may 'be made of glass or ivory, or other suitable maierial.
, Through the button two metal plates or conductors, c d, extend, and connecting these v plates is a Wire, e,preferably of platinum, alt E. EATON, of. Boston, in the county' of Suii'olk and'State of PATENT OFFICE.

necting or to be or -polesof an electric battery, the lower ends into dwhen the button and handle are brought into contact.
arrested by a pin, g, projecting intoa slot, h, or in any other. convenient manner; and when the handle 'and button are forced together,
the wires :c being. connected with a battery,"
heat 'is generated in the wire e, the battery being of such power that the electric current passing lthrough the wire shall heat it. hot enough to 'burnor char the surface of a stamp upon which the cancelar is pressed The wires connecting with the battery do not interfere: in the'. least with thefreemovevment necessary in manipulating the cancelar, .and it will be readily seen that with 'its use postagestamps can be not o'nly more perfectly vand readily marked than by the printand-marking o'ancelers now in use, but4 that' anv ineiac'eable mark can be produced upon the stamp, which e'ectually cancels it.
The wire may be heated by a current generated by frietional or other electricity.
Having thus fully described my invention,
what is'claiined is- 1. In a canceling-stamp, the combination,y
with a canceling-die, of electric conductors for heating the die, substantially asset forth.
2. In a stamp-cancelar1 the combination of a body or handle, electric conductors, and a non-conducting carrier to which is attached a platinum or other die, as set forth.
3. In a stamp-canceler, the combination of a' body or h andle,"A, electric conductors m,
and a non-*conducting spring-carrier, B, provided with a platinum or other die, whereby, e
upon striking the die upon a stamp, an electric current is generated which brands or burns the stamp, as set forth.
Witness my hand this 8th day of May, 1878,
at Dayton, Ohio.
