IMPROVEMENT IN' swimP-crmlcrirns.-

The Schedule referred to in these Letten Patent' and making part of the laine.

I, J onu GoLDsBonoueH, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improved Stamp-Canceling Machine, Aof which the following is a specilication.

Nature and Object of the Invention. My invention consists of certain devices constructed and `.arranged,.as fully describedhereafter, so as to print the date upon a stamp and at the same time cut the-same and scrape or iasp the surface, thereby so eectually injuring'it that its restoration will be impossible.

.Description of the Accompanying Drawing.

' Figure 1 is a secticnal'elcvaton of my improved stamp-canceling machine;

Figure 2, a sectional elevation on the line 12, fig.`1;

Figure 3, an inverted plan view of part of the maby aboxor case, C, a tube connected to the uppcer end-'of which slides in the arm b. a

-On a. shaft, d, within the case, turn the usual print-` ingdisks e e' e, having projecting figures or letters at the edges indicating the namesA and dates of the months, years, or other devices which it is desired to impress upon the surface of stamps to be canceled,

i the said disks being so arranged that the iigures at the lower edges shall project beyond the lower slotted face of the case C. e

In boxes fj, at opposite sides of the case, turn spindles j, upon which is. wound an ordinary inking- `band-or tape, g, the latter passing through slots h It in the caseand across the lower edges of the disks.

' lo the shaft d, at opposite sides of the printingdisks, arc hung two segmental plates, D D', having their curved edges a: serrated or cut so as to form tile or rasp-tceth, and secured to or forming part of each segment is a pinion, an.

To the teeth of each pinion are adapted those of a rack which forms one of the arms n a of a yoke, F, secured to a rod, o, extending through the tube c, and having at its upper end a knob, c', the racks being on opposite sides of the shaft d, so that when the yoke is depressed the two segments will vibrate in opposite directions.

The segments are so arranged that when the yoke Fisat the limitof its upward movement they will be in the position shown in fig'. 1, and the lower end of the case is slotted 'to permitl the segmentsto vibrate with their serrated faces slightly beyond the faces of the type or figures on the printing-disks'.

At the side of each slot, at the lower end of the case', is a straight cutter or knife, e.

The case C and yoke F, which bear against the top of th'e case, are maintained in an elevated position free from contact with the bed w by a spring, jp, in a recess in the rod o, the spring bearing at itsupper end against the endl of said recess, and at its lower end 011l a cross-bar, @which extends into the4 arm b through slots in the rod o'and tube c.

A spring, s, coiled round the rod o, between the knob -c and vend of the tube c, tends to maintain the yoke F in an elevated position in the case C.

Instruments for canceling stamps by simultaneously cutting or scoring and printing\the dates upon the same have heretofore proved ineicient from the fact that fluid inks have always been employedfor inking the type, the appliancesv for retaining the ink and depositing it properly on the type being necessarily complicated, expensive, and liable to get out of order.

By the arrangement above described I am enabled to employ the ordinary and etlicient inking-tape in connection with -devices for scoring and cutting the stamp.

. The paperto which is aflixcd the stamp to be canceled' is placed upon the bed Iw, and the knob c is struck a smart blow, so as to force down the oase O and bring the knives fu lv and the edges of the print-v ing-disks, with the tape beneath them, upon the stamp,

which is thus cut completely across its face on the lines 1c u, fig. 4, while the date is printed at the center ot' the same. The movement ot' the case is arrested as it strikes the bed lw, but the yoke F continues to ldescend, the racks n a turning the pinions fm, m and the segments l) D in the direction of their arrows, fig, 1, so that their serrated edges are carried rapidly across the face of the stamp, and file or rasp the latter, removing its surface at the points c' c'.

On removing the pressure on the knob c' the springs s and p will elevate the yoke and case, and the various parts will again assume the position shown in figs. 1 and 2.

By these operations the stamp is completely severed into three parts, the surface is entirely removed at two points, and the date is printed on the same, the stamp being thus so injured that its restoration is impossible, while the mechanism employed is simple, inexpensive, andv not liable to get out ot' order.

In place of a box or case, a block or holder, to'which are attached permanent or movable types, may be employed, theserrated segments being hun g to the sides of the saine, and instead of the straight knives/v o, knives arranged to cut away disks or' sections from the face of the stamp/may be used.

C' Zaim.

The combination of the movable case 0,21. series of printing-disks or type, an inking-band passing below the type, oneor more vibrating plates, with serra-ted edges, and the devices described foroperating said plates, causing them tol strike and traverse the face of a stamp while the latter is held against the cushion by the type.

In testimony whereof I have signed my, name to this specification in the, presence of two subscribing witnesses.

JOHN- GOLDSBOROUGH.
