Filed Feb. 8, 1957,'Ser. No. 639,024 6Claims. c1. 101 -2-69) This invention relates to a'printing machine, and more changes, specialsales, changes in merchandise or other such instances, requiring constant changes of signs and show cards throughout the store .to meet the situation.

In most instances, only a limited quantity of such signs are needed making it impractical to use conventional printing machines and methods which are rather large in size, difficult to setup and expensive to maintain. It is likewise impractical to use the services of professional printers [for such limited quantities because the cost of printing is determined primarily by the initial set-upof type rather than by quantities of printed matter. Also, in most instances, changes are sudden and signs are required in less time than professional printerscan normally supply them.

. It is therefore an object of this invention toprovide 2,942,544 PatentedJune 213, 1960 a printing machine which includes anjimprove'd inksupply means which is preferablyrotat'able and movable along the bed'of the machine to supply ink to the inkrollers in selective locations of said bed which are more advantageous and time-saving during the printing operation.

Referring to the drawings, there is shown by way of illustration, but not of limitation, a preferred embodiment of a'press-type printing machine 30 comprising an elongated frame 31 which is preferably rigidly formed as by casting or the like.

The frame 31 includes a substantially rectangular horizontal bed portion 32, reinforced as on the underside thereof by a plurality of longitudinal and

transverse ribs

33, 34 respectively. The ribs may be thickened at selective portions as indicated at 36 to form a plurality of downwardly extending. legs 37 optionally provided with adjustable bearing pads 38 to facilitate leveling of the frame.

The bed 32 as previously mentioned, is horizontally disposed on the frame 31 and may be formed integrally therewith as shown. Preferably the bed 32 is scored on the upper surface thereof as indicated by the longitudinal and transverse lines 39 (see Figures 1 and 2) and additionally provided with suitable indicia as indicated at 51 or otherwise marked to facilitate lay-out and composition of typemeans in'preparation for printing. The bed 32 is preferably formed ofa ferrous material such as castiron or the like for a reason which will be hereinafter described. It may however be formed of a separable sheet 42 of ferrous material, such as steel or the like, removably fixed to the upper surface of a frame 31'- (see Figure 27) as. by screws 43. or the like. The frame 31' may be formed in this latter instance of a lighter weight material such as cast-aluminum, or the like, where his desirable to decrease the weight of theframe. e

As best seen in Figures 2, 3 and 4, a plurality of individual type-means 44 are provided for placement on the bed means to imprint characters of desired form in the printing operation. The type-means 44 are preferably substantially rectangular in configuration with flat parallel upper and lower faces 46; 47 respectively. The lower face 47 of each type means 44is adapted to rest on the flatbed 32 whereas the upper faces 46 are provided with letters, numerals or other desired characters 46' to be imprinted.

The type-means 44 are preferably additionally provided with substantially vertical fiat sides 48, adapted to be placed side-to-side in abutting relationship to form words or numerical combinations desired. Each type-means 44 includes a transverse slot or groove 49 to nest over an alignment bar 51' conforming in configuration to the groove 49 and extending therethrough to align type pieces in abutting relationship when arranged in such combinations described.

The type-locking means 52, preferably of magnetic composition, provided, to removably secure the type .4 means to the bed 32. Said locking means preferably comprises a substantially rectangular body 53 most desirably of a magnetic ceramic material, cast or otherwise formed with a groove 54 of sufficient depth and width to snugly circumscribe the bar 51'. A pair of opposing plates 56 are provided adjacent said body. 53 and are preferably formed of a ferrous material such as soft-iron, or the like, to form a permanent magnet.

It is contemplated by this invention that the type-means 44 are first arranged in any desired combination upon the bar 51'. The type-locking means 52 are then mounted over the bar 51' at each end of said combination of typemeans and in close abutting relationship to the typemeans 4401' groups thereof. The resulting assembly is then placed upon the bed 32. The type-locking means 52, being magnetic, will adhere to the bed 32 of ferrous material, in tight relationship, locking the type pieces 44 thereon. Additional type-locking means 52 of varying lengths or groups of locks 52 of uniform length may be along the bar 51 on the bed 32.

p f It is also within the scope of this invention to provide a variety of relatively thin transparent or other non-ferrous sheets 57 (see Figure 28), such as plastic orpaper which may be placed over a ferrous bed like 32 described, individual sheets having various scales and/or indicia inscribed or printed thereon to facilitate printing composition of various Scales. Such sheets will not disturb the magnetic field of the type-locking means 52, permitting the locks 52 to firmly hold type-means 44 on the bed as described.

A pair of substantially parallel outwardly extending

longitudinal tracks

58, 59 are provided at opposing longitudinal edges of the frame 31 adjacent to the bed 32 and may be optionally formed integrally therewith as shown. The

tracks

58, 59 are preferably formed with substantially horizontal flat upper and

lower surfaces

61, 62 respectively and a substantially vertical flat outer surface 63. The outer surfaces 63 are preferably substantially parallel to each other to form opposing bearing surfaces. The

tracks

58, 59 provide means to support and guide an impression means 64.

The impression means 64 comprises a frame 66 transversely disposed over the frame 31 for longitudinal reciprocal movement relative to the bed means 32. The frame 66 includes a pair of

vertical side plates

67, 68 at opposingends thereof, tied together as by elongated tie-rods 69, which are preferably adjustably secured to the plate as by nuts 71.

As best seen in Figures 6, 7 and 8, the

side plates

67, 68 are provided at the lower edges thereof with a pair of inwardly extending horizontal stub shafts 72 on which a pair of upper support rollers 73 are rotatably mounted to engage theupper surfaces 61 of the

longitudinal tracks

58, 59 and support the frame 66 thereon for longitudinal reciprocal movement as previously mentioned.

The

plates

67, 68 are additionally provided with a similar stub shaft 74 on a lower extension 76 of the plates on which a stabilizing roller 77 is rotatably mounted to thrust force imparted by the impression means as will be described.

' As best seen in Figures 7, 17, a pair of thrust roller bearings 78 are preferably provided at the inner surfaces of'the

plates

67, 68 to bear against the outer surfaces 63 as the

tracks

58, 59, and prevent side sway of the frame 66 along the tracks.

The upper portions of the

plates

67, 68 are provided with aligned apertures 79 to rotatably support an elongated eccentric horizontal shaft 81. The shaft 81 preferably is provided with reduced eccentric ends 82 rotatably supported within the apertures 79, and bearing surfaces 83 ing webs' 107 and enlarged bosses 188.

ward side plates 68, is preferably secured to the plate as by a thrust washer 85 and screw 86. The other end like 82, preferably extends through the apertures of the rearward plate 67 and is secured within a counterweight 87 as by a screw 88 at the outer side of side plate 67.

A handle 89 is secured to an enlarged central portion 91 of the shaft 81 as by split-clamp extensions 92 of the handle and screws 93. As best seen in Figure 12, the handle '89 andcounterbalance 87 are preferably fixed to the shaft 81 in such relationship that the counterbalance 87 will normally urge the handle 89 into the substantially horizontal position shown in Figure 8 for a reason which will be hereinafter described. I

The shaft '81 is further provided with a pair of inner thrust washers 94 adjacent .to the inner surfaces of the hanger brackets 84 and a pair of outer washers 96 adjacent to the outer surfaces of the brackets 84.

The foremost washer 96 is preferably provided with a radial stop pin 97 extending outwardly therefrom and keyed as by a set screw 98 or the like to the bearing por- .tions 83 of the shaft 81. The pin 97 is adapted for arcuate movement when the shaft 81 and washer 96 are rotated, and is limited as by a pair. of inwardly extending limit pins 99 of an arcuate adjustment slide 100.

The slide 100 is slidingly disposed in an arcuate slot 101 of the upper portion of the forward side plate 68, substantially concentrically disposed in the plate relative to the ends 82 of the shaft 81 and is likewise preferably provided with a flange 102 on the inner side thereof abutting the inner face of the forward plate 68. The slide also includes an outwardly extending externally threaded pin or shaft 103 extending beyond the outer face of the plate 68 and secured by an enlarged internally threaded nut or knob 104. The limit pins 99 are preferably spaced to provide substantially a 90 travel of the stop pins 97 about the center point of the shaft end 82. .The slide #100 is movable within the slot 101 and preferably provides substantially a190 arcuate adjustment of the limit pin 99. The slide 100 may be secured in a predetermined position by tightening of the knob 104, to determine the primary and secondary position of the pin 97 andrthe vertical eccentricity of the shaft end 82 relative to shaft 81 as will be hereinafter described.

'An indicator 105 may be disposed on the shaft v103 and extending over the periphery of the arcuate upper edge of the plate 68 to move with the slide 1'08. Indicia 106 may be provided on the edge of plate 68 to facilitate accurate adjustment of the slide. 7

The depending hangers 84 include downwardly extend- The bosses 108 are transversely bored as at 109 to receive therein a flanged adjustment bushing 111. The bushings 111 are preferably eccentrically bored as at 112 to rotatably support reduced ends 113 of an elongated impression-roller shaft 114. The shaft 114includes a centrally located elongated sleeve 116 of compressible resilient material such as rubber, neoprene or the like, and a pair of collars 117 of a hardened non-compressible material such as steel or the like disposed adjacent to the hangers 84.

The bushings 111 are preferably rotatable but have a tight fit within the bore 109 of the bosses 108 to permit adjustment of the distance between the centers of the

shaft

114 and 81. A plurality of radial apertures 118 may be provided on the periphery of the bushing flange for insertion of a tool (not shown) to rotate the bushing relative to the hanger 84 and adjust the distances described. The bosses 108 are preferably split as at 119 to facilitate insertion. and rotation of the bushings 111 and are provided with horizontally disposed lugs 1121. Screws like 122 may be used to tighten the bosses to secure the similarly split bushings .111 ina desired adjusted position.

The hangers 84 preferably include outwardly extending bifurcated lugs 123 which are hingedly secured as by a pin 124 to inwardly extendingbracket arms 126 pivoted on the outer tie-rod 69 to prevent side sway of thehangem 84 about the shaft 81. i

It is apparent by the foregoing description that the impression roller sleeve 116 is supported by'hange'rs 84 of the frame 66 and is adapted to "be raised in an upper position to clear the type-means 44 magneticallyor other wise secured to the bed 32, when the handle 87fis in a normal downmost position as held by the counterbalance I 87. The impression roller sleeve 116 is capable of being depressed downwardlyto impress a resilient force on the type-means 44. When the handle 89 is rotated to its uppermost position, to rotate the shaft 81, the portion 83 of the shaft is revolved about the eccentric end 82 of of 'thejshaft to lengthen the vertical offset between the centers -of81, 78-2 and lower the sleeve. The uppermost and lowermost positions of the handle 89 may be determined by the position of the slide and its limiting pins 101 so that when the slide '100 is in its furthermost clockwise adjusted position, the impression roller shaft 114 and sleeve 116 is in its downmost position as for thin paperboard card or the like, and conversely, when the sleeve 100 is in its furthermost counterclockwise adjusted position, the sleeve 116 is in its uppermost position when lowered, as for cards of heavier thickness.

The frame 31 is provided with a pair of elongated

longitudinal rails

130, 131, adjacent to the bed means 32 and spaced inwardly from the opposing

tracks

58, 59 respectively. The

rails

130, 131 may be optionally formed integrally of the frame 31 and preferably with flat upper surfaces 132 in a common horizontal plane, extending substantially the length of the frame 31 to support an inking means 135 for longitudinal reciprocal movement relative to the bed 32. Inasmuch as the ink supply means is adjustable and readily movable to any position along the bed portion 32, it may be brought anywhere to the left, relative to Figure 1, for'example, and, if desired, immediately adjacent the card-holding means 170, or the type 44. Thus, it is not necessary to move the inking means 135 from one end'of the bed tonthe other, as in prior art devices, an d therefore rapid production and duplication of smaller signs is facilitated;

The inking means 135 comprises a frame 136 transversely disposed over the bed 32, including a pair of forwardand rearward vertical side plates 137 adjustably joined as by tie-rods 138. A pair of elongated driven inking rollers 139 are rotatably secured on the lower portions of the side plates 137. Reduced ends 140 of the rollers extend through the plates 137 and are nonrotatably fixed in enlarged flanged support rollers 141. The rollers .141 are supported on the upper surfaces 132 of the

rails

130, 131 to roll thereon and support the frame 136 for longitudinal reciprocal movement, as previously mentioned. An idler roller 142 is rotatably disposed on the frame 136 between the driven rollers 141. -The driven rollers 139 and idler roller 142 are preferably mounted in a common horizontal plane and providedwith compressible resilient sleeves of rubber, neoprene, or the like, for resilient contact with the type means 44, ,as best seen in Figure 14. A pair of elongated idler roll ers 143 are provided in juxtaposition to the

rollers

139, 142 and supported thereon. The rollers 143 may be formed of plastic, aluminum, or other suitable material a and are provided with end bearing surfaces or buttons like 144 to reduce'frictionand/or end wear against the side plates 137. An elongated cover 146 may be formed of a sheet metal or other suitable material with downrolled opposing edges 147 to snap over and be retained by the tie-rods 138. A handle -148 be secured to; the cover 146 as by bolts and nuts or the like to facilitate manipulation of the frame by the operator.

As best seen in Figures 1, l5, 5 and 16, an ink-supply means generally referred to by the numeral 150 is disposed at one end of the bed 132, to the right as viewed in Figures 1 and 2. The ink supply means 150 comprises a substantially horizontal disc-like or otherwise shaped platform 151 including a depending pivot pin 152 fixed centrally thereof. The pin 152is rotatably disposed in a vertical bore 153 of a centrally located boss 154 of a base member 155. The base 155 is preferably cylindrical in configuration and is providedwith a pair of radial limit pins 156 (see Figures 1 and extending outwardly and engageable with adownwardly extending portion 157 of a handle 158 disposed onthe underside of the platform 151 to limit the rotation of the platform relative to the base 155. The outer peripheral edge of the platform 151 preferably supported by the upper surface 159 of the base 155. j

The base 155 includes a plurality of horizontally disposed legs 161 vertically threaded to receive adjusting screws 163. The screws 163 provide adjustment means to raise or lower the platform 151 for desired intimate contact with the inking

rollers

139, 142 of the inking means 135. The screws 163 also provide slides for longitudinal movement of the ink supply means 150 on the bed 32 to bring the ink supply means as close as possible to the type-means such as 44 set up on the bed 32.

As best seen in Figures 1, 18, 19 and 20, a cardholding means 170 is transversely disposed at the other end of the bed 32, to the left as viewed in Figure 1, wherein a paper-board card to be printed is held in clamped relationship over the bed 32.

The card-holding means 170 comprises an elongated stationary member 171 fixed at its outer ends to mounting brackets 172 as by screws 173. The brackets 172 may be secured to the bed 32 as by cap screws 174.

A movable member 176 is pivotally secured in the outer ends of the brackets 172 as by stub shafts 177, and includes a substantially horizontal plate member 178 overlying the stationary member 171. The plate 178 may be secured to the movable member 176 as by screws 179 or the like and preferably includes a plurality of cut-outs 181 to form inwardly extending fingers 182 substantially overlying the stationary member 171.

A pair of outwardly extending arms 183 are secured as by cap screws 184 to the moveable member 176. Arms 183 include enlarged outer ends 186 with vertical bores 187 to receive compression springs 188. The springs 188 extend into vertical blind bores bores 187 and 189 act as keepers for the spring. The springs 188 urge the arms 183 upwardly to pivot the moveable member 176 about the horizontal pivot pin 177 and clamp the plate member 178 agalnst a paperboard card 190 indicated in broken lines in Figures 19 and 20, inserted between the plate 178 and the stationary member 171. A vertical strip 191 may be secured at the outer side of the stationary member 171 and provided with a plurality of notches 192 form fingers 193 extending upwardly between the to form an abutment stop for the paper-board card 190 inserted therebetween.

The enlarged ends 186 of the arms 183 are preferably formed with the upper surfaces 194 in a horizontal plane higher than the lowest point of the collars 117 of the impression means 64. When the impression means 64 is in a normal outer position, to the left as viewed in Figure 5, the collars 117 engage the surfaces 194 to compress the springs 188, raise the plate 178 and release the card 190. When the impression'means is moved longitudinally towards the central portion of the bed means, the collars 117 disengage the surfaces 194, and the springs 188 urge the plate 178 automatically into a clamping position to clamp the card like 190.

Referring to Figure 21, there is illustrated a modified form of type-locking means contemplated by this invention and referred to generally by the numeral 220. Type-locking means 220 comprises a substantially rectangular body 221 cast or otherwise formed of a ceramic- 189 of the bed 32. The

provided with enlarged outer ends 162 fingers 182 of the plate 178 8 iron magnetic compound with opposed elongated side plates 222. The body 221 is substantially shorter than the side plates 222 to form therewith a groove 223 of appropriate dimensions to receive therein the alignment bar 51' holding type means like 44 as described in the previous embodiment.

A further modified type-locking means 230 is illustrated in Figure 22 wherein a short rectangular body 231 of magnetic composition is disposed between a pair of side plates 232 to form a permanent magnet.

A groove 233 is formed by an offset plate 234 spot welded or otherwise secured to a plate like 232, to receive therein an alignment bar like 51 as previously described.

. The type-locking means 220, 230 of Figures 21, 22 respectively are particularly adapted to permit sets of type means on bars like 51' to be placed on the bed means 32 in'close proximity when desired.

Referring to Figure 23 there is shown a modified form of a type-means 240, adapted to be magnetically selflocking to the bed means.

The type-means 240 comprises a body 241 cast or otherwise formed of a magnetic ceramic compound and cirsoft-iron or the like to form a permanent magnet.

A transverse top plate 243 is welded or otherwise fixed to bridge the upper ends of the side plates 242. The upper surface of top plate preferably includes a letter, numeral or other desired character 244 to be printed. A groove 245 may be provided to facilitate alignment of individual type means like 240 as by the placement over a bar like 51. 7

Referring to Figure 24, there is shown a modified form of a bed means indicated generally as 200. The bed means 200 comprises a base 201 cast or otherwise formed of a ceramic material containing powdered iron or the like which is magnetized. A plurality of metal strips 202 of ferrous material, such as soft-iron or the like, is preferably cast integrally with the base 201. As seen in Figure 25, the strips 202 are preferably vertically cast integrally with the base with top edges substantially flush with the top and bottom of the base 201.' The strips 202 are preferably diagonally arranged in a herringbonelike pattern, to provide a maximum magnetic surface for the placement of the type-means like 44. It is, of course, understood that with a base means of this embodiment, type-holders such as 52 would not be needed. Type-means similar to 44, made of ferrous material, would be attracted to the magentic field of the base-200 for firm adherence thereto.

Referring to Figure 26, there is shown a modified form of the impression means generally referred to by the numeral 205 wherein like parts previously described are referred to by like numbers. Impression means 205 includes the side plates described in the previous embodiment, one of which is shown at 67, and an elongated eccentric shaft 81. A pair of hangers 206 are provided at each end of the shaft 81 adjacent to the sides 67, which include enlarged bosses 207 supported on surfaces like 83 of the shaft 81. The bosses 207 are provided with downwardly extending internally threaded portions 208 to receive one end 209 of a turnbuckle 210. The other end 211 of the turnbuckle 210 is threadedly received in an upwardly extending portions 212 of a bracket 213. The brackets 213 are enlarged at their lower ends and are preferably concentrically bored as at 214 to support the reduced ends of the impression roller shaft 114 in a substantially horizontal plane. The brackets 213 are additionally provided with outwardly extending bifurcated ears or lugs 214' hingedly secured as by pins 215 to inwardly extending brackets 216 mounted on a tie-rod 69. In this embodiment, adjustment is secured by the rotation of the turnbuckle 210 by means of an enlarged central non-circular portion. Locknuts 217 may 156' p i e to lock the tnmbuckles in the desired ad la ed position Operation ,of above apparatus To operate the printing machine embodying this invention, the type-means 44 are arranged in desired combinations upon the shaftSl. clamped in osition by the magnetic type holders 52, and placed upon the bed 32 as des'ir d- Iheimpressionmeans .66., at this time, is a i leftmo t position with the collars 117 depressing e Springs 1188 .tohold the moyable member 176 of the card-holding means. 110 intits uppermost position ready pgreceivea paper-aboard card .like 190;- The impression me ns is adjusted by the operator by means of the slide 100,in*it.s cooperatingarcuate slot 101 .to adjust the relative-position of the roller sleeve "116 for the amount of IHP 'QSSi D desired. At this time, any adjustment of the bushing 111 desired is accomplished to further achieve this adjustment.

The operator may then place printing ink upon the platform of the ink supply means 150. If desired, an ink of a uniform color may be spread over the platform 151, or on only portions thereof in alignment with typemeans such as 44 which are desired to be printed in a particular color, for instance, one side of the platform 151 may bear a printing ink of one color, whereas the other side of the platform may be supplied with a printing ink of another color to print a show-card with a plurality of colors. The platform 151 may be rotated to align the inked areas with the type-means desired to be printed.

The inking means 135 is then moved longitudinally on the rails 13%), 131 towards the ink supply meanslSi) to bring the

ink rollers

139, 142 into contact with the platform 151. The printing ink is spread over the driven rollers like 139, to the adjacent roller 143-, roller 142., the other idler roller 14-3, and then to the other driven roller 13 9.

It is to be noted that a large supply of printing ink may be carried by the rollers of the means described, which is particularly desirable when a card of large size with a plurality of type is desired to be printed.

A card like 190 is then inserted between the clamping plate 178 and the stationary member 170 into abutment with the stop strip 191.

The impression means 164 is then moved longitudinally on the

tracks

58, 59 toward the bed means 32. This movement disengages the collars 117 of the impression roller from the enlarged ends 186 of the card-holding means, permitting the springs 188 to rotate the member 176 to clamp the plate 178 downon the card like 190 and the stationary transverse member 171, clamping the card securely in place. The impression means is moved longitudinally by means of the handle 8-9. The handle 89 is normally in a substantially horizontal position, being held in this position by the counterbalance weight 87. The force applied to the handle 87 to move the impression means to the right as viewed in Figure 5 rotates the handle upwardly, lowering the impression roller 116 to its downmost position. Additional force to the right will bring the impression roller in contact with the paper-board 190 on top of the printing means 44 to press the paper or card down into intimate contact with the type-means and transfer the printing ink to the underside of the card;

When the impression means passes beyond the typemeans, the direction is reversed to move the impression means to the left, as viewed in Figure 5. The operator rotates the handle 89 downwardly, which through the eccentric shaft 81 lifts the impression roller 116 to its uppermost position as seen in Figure 8 to clear the paperboard 190 and remove the pressure therefrom. Additional travel to the normal position of the impression means to the left positions the collars 117 over the enlarged ends 186 of the card-holder means, depressingthe springs 188, to automatically release the paper-board 190. A stop 195 in abutment with roller 177 may be provided to the travel of the impression means at the ex trerne left position. The impression. roller or sleeve 116 is adjustable by meansv of the .turn struct ion 206, at either end, for leveling the same. cured by the jamb nut or like means. a
