0 represents a horizontal rocking" arm or carrier .'hich is pivoted at ne end to the underside of the tahic and provided at its opposite end with a lHMll'lllQ in which the uppcr section ol the impression roller sllztlt is journalcd. The movement ol" this arm 0 in the direction for carrying the impression roller toward the printing roller is limited by a stop 1) against which it is )icldiilirl) held by a pring o This stop is pzcl crably arranged on a horizontally adjustable arm .1), as shown in Pi 5, to permitadjustincg't'he position of this 1!! :ession roller shalt relatively to the printi rollw-shalt.

The prcl'crrcd means (or adjust ing' the arm t consists in pivot ing the same a t one end by a vertical pin o to the table while its opposite free end is connected by ub -ltiaml-slot connect ion of, o with the table, as shown in the last mentioned lic'ure.

"the impression roller has a hub it of metal which rests loosely on the top of the-dish lit and a periplu it ol' rubber or other elastic material which adapted to receive the p sure ol the print 1g wheel As Show 'n l ,1 ol'' thc drawii V t e impression roll compelled to {11111 with the disk M and the shaft It, It but free laterally reletively thereto by moons of n 13in 0 arranged on the underside of the hub cit the impression roller and projecting into openi p in the disk M. desired, this pin and o Jung connection between ts be omitted in which c moon ro ler driven solely by in the disc:

operative position relative to the brinting Wheel is eoi'istructed as follows Q represents an eccentric which is pirotcd on the shaft section itabore the feed disk M and upon the periphery of Which the hub of the impression roller is pivoted. As shown in Figs. 3 and 4, the salient part oi this eccentric projects forwardly or in the direction in which the letters move from the receiving to the delivery side of the table. At its upper end. the eccentric is provided With a rear wurdly projectin tuppet g which overhangs the impression roller. The latter together with the eccentric are held against upward movement on the shaft section t' by washer g secured by a screw to the upper end of said shaft section and engaging with the upper side of the tappet.

it represents a shifting arm and S a trigger which are arranged above the table in rear of the impression rolier and which are caused to rot ate horizontallyin unison byd orining both ol them on or securing them to the same hub r. The latter pivoted on the upper end of a vertical pin 8 which projects upwardly from the rocking carrier through at slot 1' in the table The shifting arm projects for wardly from the pivot pin .9 and normally on- ;rages at its trout end against the inner side of said tappet while the trigger normally I projects from the pivot pin 8 obliquely i 01 ward across the path of the letters and terminal es close to the periphery of the printing wheel. The movement of the shifting arm and trigger toward the letter path is limited by a stop i which is adapted to be engaged by the shil'tinc arm. The shifting arm and trigger are yieldingly held in this inner position by a spring a" connected at one end with th rear side of the hub 2' while its opposite cud is connected with a bracket 10 projecting laterally from the collar 11 which is secured to the pin s and carries the stop t. The trigger is preferably constructed in the form of a two prong l'ork and is arran ed higher than the top of the printing wheel.

Y represents a feeling or trip linger which is arranged on the upper side of the printing wheel with its free end opposite the space between the prongs of said forked trigger and adopted to cooperate with the trigger for shifting the impression roller into its opcrative josition. I

it on no iettcr is fed forward against the trigger, the same projects across the path thereof, as shown in F 4, and atsuch time the trip finger passes idly through the forked trigger during each rotation without actuonly the rear part of the latter would pi int on the letterend thus cancel the some imperfeotly and possibly miss some of the posts-go and tail to sffix the canceling date on the hat ter. '11 letter is in time when it en 'sges the triggei before the front end of the (lie'pesses the printing line in which case the letter is ermittecl to move forwardly bemveen the impression rollersnd die and eeeeive'the en tii'eimprint of the latter, so that all of the postage stamps which ei'e orolinei'ily sifi ed to letters are conceledend the date is mixed thereto in its entirety:

While the trigger isin the position shown in Fig. e, the forward rotstioh of the impression roller by frictional contest with the so centric causes the latter to be slso turned in riphery of the letter from smutting the imletter engages inerk on the lsiftsi' iii! -ng the some o. .-.ecti;:.n until the tsnpet engages with the outer side of tee s Lfting arm, causing the eecentrie'to-move the impression roller away the 'pyinting Wheel sn'd'prevent the inked type on the pepressio'n roller.

The trip tinge? is mounted wheel slightly in e..-:lv-enoe of the (lie and feed flange t end with the trigger so as to bl li gt the ge between its prongs or tines the trio finger engages with the letter and gushes thessme together with the trigger laterally toward the impression roller and immediately thereafter the lower pert oi the letter is between the feed disks o1? flanges of the printing wheel and impression roller shafts and shot forward. At'the some time, the shifting arm by engaging; with the tsppet turns the eccentric a direction opoosite to that in which the iinpres n i'ollei normally 1'0- tstes, thereoy f5! mg the impression roller bodily toward the printing wheel and consing the (lie of the which at this time is in the printing po n t, piodlice a post the forward movement of the same. The impression roller remains in. this position (hiring the entire passage of the letter. While the impression roller is out of sci-ion. or in its retreated po- 'sltion, the she mgerm is morenearly perellel with the face of the teppet and thelatter is engsged new: its base or pivot by the outer free end of the shifting arm, as shown in Fig. 4. But when the lIHPIQSSlOHIOlleI sews ment with the stop 0, .but when a letter or r is action or in its operiitive os ition the. shifting arm is arranged at rig t angles to the face of. the tsppet and engages its outer end farther from its base or ivot,-ss shown r in Fig. 3, therebypositively coking the inipression roller in its Working position end preventing the some from being defile-steal" by the lateral pressure ofs letter into an iii- 1 operative position so long as e pieeeoi mail mstter is passing between the printing whee} and im ression roller. /Vhem the we; end of the otter clears the t igger, the latter-is vI immediately projected across the lettenpatl i by the spring t in position to intercept the next letter. As the trigger and shifting {H111 resume their former positiomthe forward rotation of the impression roller causes the; F eccentric to lie-turned outwardly or away from the letter nth, tliei'eby esi rying" the impression roller otlily in the sense direction enil preventing engagement of its peri' lien-5 with the inked (lie of the printing whee: during any idle rotor Y movement thereof, whereby the books 0 subsequent letters ere evcnted from becoming soiled or smntted. ihe rate of movement at the periphery of the printing wheel and impression roller 'and their feed disks is the some, the gearing between the shsfts of these parts being suitably pro ortionecl to obtain this result.

ll desired, the impression roller H may be mounted concentrically on the shaft 9 and 'intie g wheei G may be mounted on the eeeentrie end moved bodily toward and from the inipi'ession rolleir, this beings modifieetion of my invention end shown in Fig. 6.

While canceling or merlzing letters of ordinery thickness, the carrier 9 does not change its position and remains in engagepieee of mail matter of unusual thickness 1% enters between the printing wheel and impression roller, the carrier together with the parts mounted thereon ere deflected the ree quired extent, this movement being resisted by the springo which again returns the parts to their normal position.

As the letters issue from the impression roller and printing wheel they stand in front of s rot-my pecker W which is mounted on the upper end of s shaft w and swee s through on opening in the rear part of t e front well B forsuccessively stocking the letters on the delivery end of the table. Motion. is transmitted. from the shaft of the printing wheel to the separator shaft by gear wheels m, as and :e and to the pecker shelf; by gear wheels :6, '5; end 2, as shown in Fig. 5.
