' Application filed May 7,
To (/77 whom; it'mag concern:
Be it known that I, Wnsnnr J. BALKWILL, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Printing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part or this specification. and to the reference numerals marked thereon.
This invention has to do with printing apparatus and more speriallywith printing machines of comparatively small size adapted for printing relatively small work blanks, the chief object of the invention being to provide a simple. practical and efficient machine ot the above character capable of rapidly and accurately printing :blanks such, for example. as stamps, labels and the like, connected together in the form of a web or strip. ,Another object is to provide sucha machine having means cooperating with the usual lines of weakening or perforations between adjacent blanks of the strip for insuring registry between the printing members and the individual blanks at the printing-point. Further objects are to provide a machine of this type having convenient and efficient work holding and managing means.
To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described. the novel features being pointed out in the claims at the end of the specification.
In the drawings: Figure 1 is a side elevation of a machine embodying the present invention.
Figure 2 is a top plan view of the same. Figure 3 is a viewsimilar'to Figure 1 of .the opposite side -ofthe machine.
. Figure 4 is an elevation of the end of the machine as seen from the right in Figure 1.
Figure 8 is a sectional view substantially on the line 8-8.of Figure 6.
Figures 9 and l are sectional views of Figure 5- is an elevation of the opposite 1921. Serial No. 467,51.
Figure 1 but in different positions.
Figure 13 shows a work blank, such as a stamp, printed by the machine.
Similar reference characters throughout the several views indicate the same parts.
The present embodiment of the invention. which, is disclosed-herein merely by way of illustration of the principles involved and a preferred practical application thereof, is a machine adapted to be located on a table or similar support for operation by hand or by a small motor for printing work blanks of comparatively small size, as, for example, in pre-cancelling postage stamps. The latter are commonly obtainable in the form of a rolled web or stripwith'lines of weakening or perforations between adjacent stamps for convenience in separating the-same, and the machine is provided with reel means for holding a rolled strip of this character for supplying the 'same'to the machine, and also with means for automatically rewinding the strip after the printing operation. Between the reels the work passes along a bedand between cooperating printing rollers which are rotated to simultaneously printand feed the strip along, the rollers being so construeted as to momentarily release the strip hetweensuccessive printing impressions. In
this application of the machine it. is desir- I able for the printing surfaces to register with the individual stamps so as to make a complete impression on each, and means are therefore provided for engaging and positioning the strip relative to the printing'rollers when released by the latter between suevessive printing impressions. together with devices for preventing inadvertent movement of the work on the bed, or inking the printing surfacesand other parts,.the construction and function of which will more fully appear froma detailed reference to the drawings.
The main supporting frame for the machine comprises side plates 15, Figure 1,
fixed to each other in spaced relation as by bolt means 16. The side plates are provided with feet 17.by which the machine may if desired be secured to a support. r
Journalled at its ends in the frame plates is a shaft 18 on which is fixed between the plates, Figures'6to 8 inclusive, a printing roller 19 on the periphery of which are one or more printing means or plates 20,
three ,being shown in the present instance, equallyspaced from each other circumferentially of the roller.' Between the printing plates the roller is reduced 'in'radius, or cut away, as at 21, to clear or release the work between successive printing impressions. The roller 1n the present instance is rotated by means ofa hand crank 22, Figure 1, on the outer end of shaft 18, and
' during rotation the printing surfaces deengagement with the under side 0 the work strip.indicated at 24. The wor scribed-r are brought through an opening 23 in the work bed into printing and feeding bed, as shown at 25, is preferably a sheet metal plate resting on the top ofthe frame with ,fianges engaging the sides of the latter and secured thereto-as by screws 26.
On the side of the work opposite the printing roller 19, above the workbed, IS a cooperating roller 27 carried on a shaft 28 journalled at its ends in a movable frame 29 having side pieces pivotally supported sideplates of the frame.
vided forrotating roller 27, positively, at
on a stud shaft-30 mounted on one of the Means are prothe same peripheral speed as the printing 4 roller, comprising a pinion 31 on the shaft of the latter meshing with an idle pinion 32 on the frame which in turn drives a large gear ,331fixed on one end of shaft 30. Mesh- .ing with gear 33 isa pinion 34 fixed on shaft 28 of roller 27 to drive the shaft.
The printing surfaces may of course have various forms but it is preferred in the pres of posi-tiv ely feeding the work during the printing impression, in cooperation with the upper roller 27. To this end the latteris preferably formed inthree sections, Figure 2, the end ones 37 .ofwhich are fixed to theshaft 28, so as to be positively driven, while the intermediate section 38 is freely rotatable on the shaft and is .driven by,
printing characters 36 whichwill at different times engage different portions of section 38 so as to wear the. latter'more evenly. Tt is apparent from the aboveconstruction that-as handraiik 22 is rotated rollers 19, and 27 are positively driven and as the printing :surfaces 20 of the roller 19 approach. the point of tangency of the rollers the latter engage the, opposlte sides of the work in rolling, printing and' feeding contact, the .work being'alternately released between successive printing engagements by reasonof the cut away portions 21 intermediate the printing surfaces. Means are provided for inking the printin'g surfaces 20 comprising an inking roll 39, Figure 6, rotatably supported by shaft 40 in such position as-to apply ink to the surfaces during rotation thereof; Roll 39 contacts with a rotating roll 41 on ashaft 42 mounted on a detachable frame 43. The latter'is provided with horizontal'slots 44 and 45 engaging studs 46 and 47 respectively on the frame, a lever 48 being adjustably supported on a pivot 49 on frame43 and having a vertically extending slotfor engagement with stud 47 to. detachably secure the frame in place. Roll 41 clips into ink ina reservoir 50 on frame 43 so that 90. an adequate supply of ink for the printingsurfaces is constantly maintained.
In order to restrain the work agains'; inadvertent movement on the bed there is provided a cross bar 51 onframe 29 preferably integral with the side pieces of the latter.
Fixed in the cross bar 51 are vertical bearing sleeves 52 and53 in which are slldably carried spindles 54 and 55'. respectively, fixed at their lower ends to a presser foot or plate 56 arranged to bear against the upper side of the work. Springs 57 coiled about sleeves 52 and 53 serve to yieldably press the plate against the Work, spindle 55 having at its upper end a screw-58 the head of which limits the movement of the spindles in their sleeves? when frame 29 is moved away from the work bed, as will be pres-, ently explained. The work bed is provided with upturned lugs or flanges 59, Figure 1 10 11, forming a channel in which the work is 'guidedfand held by the presser foot. Frame 29 carries at its right hand end, Fig- "ure '6,- a cross rod 60 on which are pivotally supported the side arms of a bail 61, 115.
Figure 1,.straddling frame 29. The arms are provided at their lower ends with slots 62 for detachable engagement with studs 63 on the main 'frame for holding frame 29 in operating position with roller 27 against the I work. By meansof'a handle 64 on-bail 61, however, the latter may be rocked to dis engage studs '63 after which frame 29 may be moved about shaft 30 to the elevated po sition indicated in Figure 12, in which position roller 27 and presser foot 26 are moved clear of the work bed so that the latter is left exposed'for the convenient insertion and removal of the work. I i
Means are provided for holding the pivno the work as fed to the reel.
of an arm 67 having a longitudinal slot 68 embracing a pair of studs, 69 on the main frame so that the arm is movable toward and from the end of the side piece of frame 29.- A spring 70 fixed to one of the studs 69 and to arm 67 urges the latter toward the frame side piece and when the frame is raised its recessed portion 65 is engaged by the end' of arm 67 and theframe isth'us yieldably retained in elevated positionr The work may be supplied to'the printing members and disposed of after being printed in various ways. In the present instance it is preferred to provide means on the main frame forholding the work and supplying the same to the rollers comprising a reel or spool 71 rotating freely on a shaft 72 'mounted on one end of the main frame. From this reel the work is led along the printing bed under the presser foot 56 and between. the printing rollers to the other end of the work bed where there is preferably provided a second reel orspool 73 rotated automatically for rewinding the printed work. This reel is in the present instance: supported on a shaft 74. Figure 9,
which is rotatably carried in an elongated bearing 75 fixed onthe .main frame and rotated by means described hereaften- Since this reel in the present embodiment is merely for winding up the work as the latter is fed through the machine by the printing rollers or by other means described hereafter. there is preferably provided for .-it a yieldable driving connection transmitting a force sufficient only for winding up To this end the reel 1s rotatably carried on shaft 74 and the inner flange 76 of the reel is provided with'a series of openings'77 or other engaging means with which cooperates the curved end of a srin fin er-78 extendin I through an opening 79 in and carried by a flange-30 fixed on shaft 74. From this construction it is apparent that as the shaft is rotated by means presently to he described the reel is vieldably driven by engagement of the finger 78 with the apertu'red flange 77. This reel, 'as also the work supplying reel 71. preferably have their outer flanges reniovabljf carried in any suitable ma'nner,'
for convenience in the application and detachment of the work. Tn this construction, which is the same fol-both reels 7]. and 73. the outer flange of reel 73 is fixed on a hub 81 rotatable and longitudinally slidable on the reduced outer end of the shank of the reel or of the shaft 74. The hubis provided with a radially extending bore 83 in which is carried a spring pressed ball 84 yieldably engaging in a circulargroove 85 in the extension 82, by means of which construction the outer reel flange may be readily removedand replaced when removing and replacing the work. The shank of 'reel 73 is.provided with a slot 85? or other means for attaching the end of the work strip thereto. The means for driving shaft 74and reel 73 comprises a pinion 86 fixed on' the shaft and meshing with the gear 33. i
As already stated, it is desired to have the printing impressionsregister with the individual stamps to'insure a complete impression on each. It may not be feasible, however, to adjust the strip when inserting it in the machine so that the first stamp to be printed registers with the printing rollers properly for this result. Nor has it been found satisfactory to rely upon the feeding action of the printing rollers alone to advance the strip at each impression a distance equal to the width of a stamp in the direction of feeding movement, as this feeding action may vary with the speed of operation and other considerations. It is preferred therefore to so dimension the printing means as to advance the work at each impression a distance somewhat less than the width of a stamp and to provide means for positioning the work relative to the printing rollers each time it is released by the latter between successive impressions. gThis'ineans or positioning device comprises preferably one or more reciprocating, pointed fingers 83, Figures 7 and 11,
projecting upwardly through an opening 87 in the work bed and yieldabiy supported cars 91 on opposite sides of a reciprocating carriage 92 having at each side a pair of rollers 93. Figure 1. working in slots 94 in the side plates 15 of the main frame.
Earhfinger 88 has aslot loosely embracing a second spindle 95 carried by ears 91 so that it has a limited pivotal movement toward and from the work. being vieldably moved to bear against the latter by means of aspring 97 on the carriage and engaging each finger.
As the positioning device operates upon the work when the latter is released by the printing rollers to position the same before each engagement thereof by the printing surfaces, there are provided means for efi'ect mg a reciprocating movement of the posltioning device in timed coordination with the rotation of the printing roller 19. This coordination connection comprises a pair of plates 98 one on each sideof carriage 92 and movably connected with the latter by being pivotallysupported on the spindle of one of the rollers 93. Plates 98 extend past the ends of the printingrollerand are pivotally connected to arms 99 which in turn are pivotally supported on across shaft 100 carried by the main frame. One of the arms 99 carries a roller or follower 101 held in contact with an end of the printing roller at one side of the printing surfaces thereon, Fig ure 8,-by means of a spring 102 fixeid to one of the plates -98 and the main frame. A This I end of the printing roller is provided with projecting portions 1b3having substantially the shape'of the printing bars 'and with similar intermediate cutaway portions. Roller 101 thus engages with a cam like'surface on-the' printing roller so shaped as to reciprocate the positioning device so that, just prior to each printing engagement of the Work, the fingers 88 are moved toward the left, Figure 6, and their ends engage the lines of weakening or perforations in the work strip and move the latter past the presser foot 56 and relative to the printing rollers. The latter thus always engage a stamp'or; work piece in the desired spaced relation to the'marg'ins ofthe latter, ,or in other words, so that a complete printing impression is made approximately centrally of each stamp. f
The operation of the machine has been infd'icated in connection W'th the above description of its construction. To apply arolled strip of stamps to the machine. frame29 is released and raised by means of handle 64 ously print and feed the work, printing the so as to clear the Work bed. The outer end of reel 71 is removed and the rolled strip placed on the shank of the reel after which the outer flange of the latter is replaced. The end of the strip is carried along the work bed to its other end and engaged in the slot 85 of the shank of the opposite r'eel 73. Rocking frame 29 is then lowered and secured in position'and the machine is ready for operation. Rotation of shank 22 produces a preliminary reciprocation of fingers 88 which slide over the under side of-the work into engagement with a line of per-' forations into which they enter so as to ad? vance and position the work between the printing roller.
point the'work is thus properly positioned for an impression. The rollers simultanelatter as indicated in Figure 13, after which the work is momentarilyreleased and again positioned if I necessary by the. reciprocating When one of the printing. surfaces of the latter reaches the printing fingers. The printing impressions and the alternate positioning" action of fingers 88 I I thus occur in proper sequence and the work is accomplished accurately and rapidly. The driving connection with the winding reel'73 transmits a force sufficient only for winding'u'p the .work fed to it by the printing rollers and insufficient to move the Work under the presser foot so that the feeding of the work is controlled alone by the printing members and a positioning device. the roll has been printed and transferred to reel 73, the outer end of the latter may be removed and the roll detached .for use. apparent from the drawings the machine is compact and self contained in" character and the construction employed is simple and practical in form. The various parts are convenient to manipulate so that the work may be quickly applied to the machine and expeditiously and accurately printed.
