,i i Specification forming part of Letters Patent No. 48,338, dated `June 20,1865.

To all 'whom 'it may concern:

Be it known that we, THOMAS S. HUDSON and ANTHONY HARDY, of East Cambridge, in the county of Middlesexand Stateot' Massachusetts, have invented anew and useful Improved Machine for Canceling Revenue-Stamps; and we do hereby declare the same to be fully described in the following specification and represented in the accompanyingdrawings, of whichi Figure l is a side elevation. Fig. 2 a central and'longitudinal section, and Fig. 3 a.

transverse section, of it.

The natureof the main part of our invention consists in combining with devices used for printing the month and year, or the name or names ot' one or more persons, plaees,orthings, a changeable mechanism or series of types by which the day ofthe month, whatever such may be, may also be printed at the same time with the other imprints made by the devices -above mentioned; and our invention further consists in combining with the aforesaid canceling or printing devices a chamber or receiver for holding the types indicative of the months, or the years and months; and our invention further consists in the combination of a chase or separate type carrier or holder with the plunger, and the series of changeable types,

' to be hereinafterdescribed.

In the drawings, A denotes the frame of the machine, it .being constructed of the form represented, or in any other suitable for the purpose.- lt has a bed, a, on which the papercarrying the stamp to be canceled is to rest while bein gimprinted by the machine. The said frame supports-a tubular plunger, B, which isprovided with aspring, b, for' elevating it; anditalso has a head, c, on its top, such head being to receive the blow of a persons hand when applied to the plunger for the purpose ot' depressing it toward the bed. There is a rectangular cavity, d, formed in the neck e of the frame, and provided with a cover, f, such cavitybeing to contain the types for printing the names of the varions months and'years. i

At the lower part of the plunger there are sockets g g, for the reception of projections It h from the chase h', which is held to the plunger vby one or more clamp-screws, t'. This chase, formed in under side view as shown in Fig. 4', and in side view in Fig. 5, is a typeso made as to be jcapflble ot' printing the name or words that do not require to be changed-as, for instance, the name ot' a person or place-and it` contains tapering recesses or chambers k k for holding other types for printing the name of a within the plunger inzmanneras shown inV the drawings. The said endless chain m is to Contain thirty-one links, which are to have pro-- -jecting from them gures for printing the various numbers, from one to thirty-one, indicative ofthe days ot' a month. On the shaft n i.

of the upper sprocket-wheel isa catch-Wheel, o, provided with a spring-catch, p, projecting from the'head c, the same serving to fix the chain in position when any one'of its links may be brought into its place for printing..

A printing-ribbon, D, applied to wind on two axles, q r, arranged in manner :1s-shown in the drawings, extends underneath and against the pri n tin g-surface ofthechase, such printingribbon being covered with a pigment or com position'which will offset when pressed on paper by the chase and its type.

To the bottomotl the frame A we apply one or more elastic cushions or masses, s s, of vulcanized india-rubber, the same bei-ng not only to prevent noise, but to relieve 'the hand from the effects ot' the blow on tlie ,head of the pun ger durn g the act of driving'the plunger downward. They also serve tob protect the types from the effect ot' concussion.

The mode of operating our invention is to place the paper having the revenue-stamp on it on the bed, and by a blow of the hand on the head ot the plunger force the plunger and the printing-ribbon down upon the stamp, so as to cause an imprint to take place on the stamp.

I Our invention also is applicable to poststamping letters, as Well as various other uses.

What we claim as our invention is- 1. The combination of the endless chain of types and its carrying mechanism with the plunger. y

2. The combination of' the endless chain of types and its carrying mechanism with the plunger and the chase, the 'Whole being :Lrranged together as specified.

The combination ot' the endless chain of types and its carrying mechanism with the chase, the plunger, and printing-ribbon, arranged as specified. y

4. The combination of the type-chamber d in the neck c of the frame with the endless chain of type, its carrying mechanism7l the chase, and the'plunger, arranged to operate as described.
