METER PRESS This invention relates to improvements in machines in which indicia printing means are associated with meters for indicating M the total number of impressions made and for limiting the use of the machine to a predetermined number of impressions.

More particularly my invention relates to the indicia imprinting of metered permit matter, such as mail pieces, admission or sales tickets and the like in that there is involved recording mechanism to be set by an authorized person for a given number of impressions, and which automatically prevents a impressions after exhaustion of the preset 15 meter number.

The present showing may be regarded as refinements of the printinghead disclosed in av copending application entitled Printing press, filed by me on June 30, 1925, Serial 20' Number 40,631.

Objects of my invention are:

T 0 provide simplified means for directing and driving the printing member in a substantial; right line path of movement.

To provide a guard for the printing memher and an inking device which coact with a platen to provide continuous completeenclosure of the printing member to the end of g preventing unauthorized impressions.

30" To provide a cushioned platen and platen carriage wherein the density of the cushion body and the tension of the carriage may be varied for purposes of grading the impression for adaptation to variably dimensioned and contoured impression receiving pieces.

To provide more convenient access to the meters for purposes of resetting and care..

To provid means for relatively moving the printing member and inking device whereby to assure certain and uniform inking.

To provide readily accessible means for supplying ink to the inking device.

To the above purposes my invention con- '55 s in certain details or the construction,

rrangement and combination of parts as ereinafter fully, clearly and concisely described, definitely pointed out in my claims and illustrated by the accompanying drawings in which Application filed November 13,1928; Serial No. 819,147.

Fig; 1 is a longitudinal sectional elevation of the meter press taken substantially on the median line with the printing member shown in non printing position.

Fig.- 2 is an inverted plan view of the printing member, guard, inking device and their actuating means, with certain parts broken away and the meter shown by dotted lines in open, or accessible, position.

Fig. 8 is a transverse sectional elevation showing the actuating meansfor the printlng'member, guard and inking devlce, certain parts being broken away for clarity of illustration.

Fig. l-is a sectional elevation, taken substantially in the line H of Fig. 1 showing a detail of the casing elements providing proper relative fitting; and bearings for certain of the actuating parts.

Fig. 5-is a diagrammatical elevation of the guard and inking'device as at the printing interval, certain parts being broken away and in section.

Fig. 6 is a the coupling driving shafts;

Fig. 7 is an end elevation of the driven shaft showing the cycle relating tenon.

Referring, by numerals, to'the drawings, 10 and 11 designate respectively the upper and lower casing elements, which jointly form an enclosure for the operatingmechani'sm and a throat 12 for the insertion, or movement, of the print material into, or through, the press. The casing elements are detail sectional plan View of for relating the driven and adapted as at 13 for proper relative fitting and positioningand secured as by means such as shown in the recited copendingapplication.

The end walls of the upper casing element support bearings 14 and 15 in which is r0- tatably mounted the driven shaft 16, forming.

adrive for all the actuating parts of the press andv which is arranged for connection with power as by a coupling 17, which provides readily separable and positive cycle relation with a driving, or motor, shaft 18.

The shaft carries a cam 19,.for the operationof the printing member ;.a cam 21 for the operation of the guard box 22' for the printing member; a spur gear 23 for operating the meters of which there is the resettable meter 24 shown, and a second totalizing meter, not shown, but similar to that shown in the recited copending application. The shaft also carries a locking element 25 which coacts with a meter controlled element 26 to prevent shaft rotation upon exhaustion of the present meter number, and the shaft further provides support for a unidirectional element, such as the ratchet wheel 27 acted upon by pawls 28 carried by the casing.

As shown the reset meter 24 is carried on a movable part of the casing, which by preference is a part of a side wall, or door, 29 mounted as by ahinge 30 to swing outwardly, as shown by dotted lines in Fig. 2. Secured to the casing surrounding the door opening is a housing 31 which prevents access to the interior of the casing proper and tampering with the actuating parts therein when the door is open.

The printing member is carried on a frame, or yoke 32, having a length substantially that of the casing and which is mounted on a pivot 33 for rocking motion providing an approximate right line path for the printing member,-which pathv is further and positively defined by a track 34, fixed to the casing and grooves or followers 35, movable with the frame 32.

A frame, or yoke 36, similar to the frame 32 carries the recited guard box 22, which has a front wall, and two side walls and is open at its rear and the guard box frame is mounted for rocking motion on the recited pivot 33 and its path is positively defined as by tracks 37 and followers 38.

Carried by the printing member is an antifriction roller 39 which coacts with cam 19 for the movement of the member to print-.

ing position in opposition to a spring 40 which restores the member to elevated or non printing position. 7

Similarly the guard box carries a roller 41 for coaction with cam 21 and isprovided with restoring springs 42.

As best shown in Fig. 3, the cam 19 is substantially of elliptical contour; bears oecentered relation with the driven shaft 16 and includes in its face a short-concentric surface 43 resident at oneend of the major axis, for the determination of the upward limit of.

printing member movement; relatively longer, concentric surface 44 at the opposite end of the major axis for determining the downward limit of printing member move: ment and at the sides of the surface 43 dwells 45 and 46 providing,respectively a lag of printing member movement the initiation of its movement froinrest to printing position and a-similar lag following its printing cycle and immediately preceding its restoration to rest POSltlOIl. 1 The cam21'1s substantially semicircular,

its major face length 47 being concentric to provide holding the guard box in position to completely intercept the throat 12 during the entire movement of the printing memher, in both directions across the throat; the cam face also includes a dwell 48 located medially of the face length 47 and cycle related to the recited surface 43 of the cam 19 whereby the guard box is held to its upward limit of movement synchronously with the printing member, and theface further includes face lengths 49 and 50 lying between the dwell 48 and the extremities of the major concentric length .47 and bearing such angular disposition downward relative to the dwells of the cam 19 as respectively affect downward movement of the guard box prior to downward movement of the printing member and similarly upward movement of the printing member prior to upward movement of the guard box.

Theinking device comprises a pad 51 carried between cheeks 52, 52 mounted for lengthwise movements of the casing as by keys 53 on the cheeks and tracks 53' on the arms of guard box yoke 36. The movement for the inking pad consists of bell cranks 54 whose long arms are related to the pad as by pin and slot connections 55 and whose short arms are related to the yoke 36 as by links 56.

Depending from each arm of the yoke 36 is a flange 57 to which the links 56 are pivotally connected and extending between the flanges is a guard wall 58 for interception of the throat when the guard box proper is in non intercepting position.

'The ink supply to the pad comprises a roller 59 mounted on the guard box yoke'in the path of the pad a well, or supply tank, 60 in communication with the roller and open at its upper end and a filling spout 61 fixed to the casing and provided with a removable and replaceable closure 62.

Immediately under the throat 12 the end and two side walls of the casing element 11 are shortened, in height for the accommodation of the platen carriage 63 which is yieldingly supported as by springs 64 and which has limited upward movement as by the opposed ribs, shown at 65 in Fig. 3.

The springs are supported on a false bottom 66 which also furnishes support for the platen proper 67 which by preference is formed of soft rubber.

For impression grading there is provided means for varying the tension of the platen carriage springs and the density of the platen which is shown to comprise opposed wedges 68 and 69 and means such as the screw 70 to aflect relative linear movement of the wedges and consequent raising or lowering of the false bottom.

The recited coupling 17 comprises a mortise joint and a guard which is movable to prothe mortise 72 formed as an axial cut in the end' of the driving, or motorshaft 18. To provide cycle relation of the shafts the tenon, as shown in Fig. 7 has graduated sectional dimensions transversely of the shaft and the J mortise is correspondingly shaped to theend that there is requirement for definite shaft ositioning prior to coupling which is accomplished, only by fitting the thinner end of the tenon over the wider end of the mortise. The guard is tubular, preferably constructed as a sleeve 78 having'a cut away 74 for covering or uncovering, upon rotation, the tenon and mortise when coupled and is held to either limit of its rotational movement by means of a bayonet joint 75 and spring 76.

To prevent axial separation of the two shafts the tenon and mortise, as shown in Fig. 6 are tapered axially.

By reason of thedescribed timing of both the initiation and termination of the movement of the guard box relative to corresponding cycle movements of the printing member there is imparted to the ink pad a movement providing contact with the printing member only at the rest interval of the printing member; its movement to clear the printing member being first to drop or recede from the printing member as affected by joint actions 9,3 of the face length 40 of the cam 21 and the dwell 45 of the cam 19, then the rapid and full movement of the pad in full clearance of the print member, and to be reinked, by the surface length 49 of cam 21 prior to in le itiation of the downward or impression movemerit of the print member as subsequently affected by a length on cam 19' immediately following the dwell 45, conversely the ink pad is restored to rest position against the print member by similar related cams 19 and 21.

The length 43 of cam 19 coacts with the dwell 48 of cam 21 to affect bringing the pad and printing member together with a slap or quick, sudden blow whereby to assure thorough inking of the print member.

The structure of the press may be varied in form without departure from my invention as hereinafter claimed. The showing of 557 this description and the drawings being merely in illustration of one embodiment of my invention in response to the statutory requirement to applications for patents.
