BACKGROUND OF THE INVENTION Embossed cards are widely in use as credit cards (among other uses) partly because they enable the merchant or dispenser of services to print accurately the name and account number of the holder of the credit card on a manifold of forms. Thus, when an embossed credit card is placed in a suitable machine and the machine is operated to press the credit card against the manifold and move it over the manifold, the enibossed information is printed by carbon paper inside the manifold on the various sheets of the manifold.

Heretofore, problems have been caused by variations in the thickness of the credit card, variations in the thickness of the manifold, variations in the thicknesses of the plates of the printing machine, etc. Printing machines have been relatively complex and expensive, and one purpose of the present invention is to provide a simple, less expensive, but more practical machine.

One reason for the complexity and expense has been the use of springsin the mechanism which urges the roller against the embossed credit card, in order to achieve the pressure and to coompensate at the same time for differences in thickness. Such springs have tended to break and to require replacement or to cause trouble in other ways, and they have not been able to compensate .fully for the differences inthicknesses in different kinds of credit cards or even in different batches of the same credit card, etc. One often sees a credit card machine of this type where the vendor has pasted several thicknesses of sticky tape on one part of the anvil of the machine in an attempt to build yp sufficient thickness to get an even impression, and even more often one sees uneven and practically unreadable impressions on some of the copies of the manifold, if

not all of them. Thus there have been problems in obtaining legible and uniform printing from the embossed card.

Another feature which has been wanting in prior art machines has been ready adjustability once unevenness is found. Ordinarily such machines have not been adjustable, or where they have been adjustable, the have been adjustable only at the factory or only by completely disassembling the machine, so that adjustment could be done only by an expert.

Another difficulty met with machines for printing from embossed credit cards has been that the machines have often been limited to the use of one type of form. Sometimes this is quite all right, and one form of the present invention is directed to that kind of machine.

But often it has been. desirable to use the embossedcard to print on larger sizes of paper for any of various reasons, and in those instances the machines heretofore in use have been unable to do this'and such operations had to be done entirely by hand or else the card used only for making a hand-printed copy.

Complexities, highoriginal cost,.poor maintenance ability, lack of easeof adjustability, and reliance on springs and other parts that tend to break have characterized the prior art.

SUMMARY OF THE INVENTION The present invention provides a springless printing machine for use with embossed cards, a machine that is capable of ready adjustment and, in some forms the invention, can be used on many sizes of paper. The avoidance of reliance on springs is one of the important features and is accomplished by a freely swinging mounting of a yoke carrying the roller in such away thatwhen the yoke isurged toward one direction the roller is forced down firmly against the credit card, the manifold, and an anvil; whereas when the yoke is urged toward the other direction, it simply swings the roller away from the manifold, operating without springs and without any complex arrangement to prevent blurring of the forms by preventing reprinting. The journaling of the printing roller and the suspension of the yoke are such that there is ready adjustability to place more pressure on one end of the roller than the other, or to equalize them, or to change the pressure of the printing roller on the embossed card at any time.

Another feature of the invention is the provision of a novel ba's'e'emsias which 551T lie-readily adap ted to different types of credit cards and to different uses. The extrusion used in this machine not only lowers the ex. pense of original manufacture but provides for reinforcement, for reception of screws, for marginal controls, for addition of storage boxes, and other uses.

One form of the invention provides a stationary base,

whereas another form of the invention provides a base which can be swung open and which can take a variety of different sizes of paper, some of which may even be larger than the machine itself in area. Both forms include a movable head carrying the printing roller and its yoke.

DESCRIPTION of SOME PREFERRED EMBODIMENTS The imprinting machine of FIGS. 1 through 4 A machine 20 embodying the principles of the invention is shown in FIGS. 1 through 4. The machine 20 is especially well adapted to the regular use of a particular credit card or type of credit card along with a particular size of form. Sometimes large credit card organizations have forms which are substantially identical in size to those of other credit card organizations, and in this instance the forms and cards may be'interchangeable in the machine 20. some adaptability is also possible, but the main idea here is to provide a simple, inexpensive, foolproof machine for use with a particular type of credit card and where uniform, repetitive actions are performed.

The machine 20 includes a base extrusion 21, a very important part of the invention. This extrusion 21 may be made from aluminum alloy, for example, and as shown in FIG. 2, especially, it will be seen that'it provides a horizontal table portion 22, two vertical suporting side portions 23 and 24, and two

base portions

25 and 26. The

base portions

25 and 26, the vertical portions 23 and 24, and the table portion 22, combine at their outer edges to provide a pair of guides and

raceways

27 and 28 which, as will be seen, accommodate sets of rollers for the movable portion of the machine 20. Thus, outwardly extending

flanges

30, 31, 32 and 33 provide upper and lower rails for the rollers.

On one side of the extrusion 21, above the table 22, is a square channel or guide member 33, provided by an upwardly extending portion;34 and an upper portion 36 parallel to the table 22, this entire structure being an integral part of theextrusion 21. Along the other edge, is an inclined angle portion 37, also integral with the extrusion, providing another guide member. Beneath the surface of the table 22'is provided a'series of reinforcing

channels

38, 39, 40,41 and 42, which may be generally cylindrical in form, as shown, with aslot near their bottom. Thus, there may be a center such channel 40, two end channels-38 and 42, and two

intermediate channesl

39 and 41. These channels not only serve for reinforcing but also receive screws at each end for holding the assembled device together. Thus, as shown in FIG. 1, two

end pieces

44 and 45, which are L-shaped, are held to the extrusion 21 by screws (not shown in these views but similar to those in FIG. 6),

The base extrusion 21 with its

end members

44 and 45 combine to provide the stationary part of the apparatus 20. .The movable part of the apparatus is provided by a head or carriage assembly 50. The carriage assembly 50 includes a cover member 51 having a

pairof side plates

52 and 53 joined by ba transverse or cover plate 54, which may be shaped like an inverted U. Each

side plate

52, 53 carries rotatably a pair of

transport rollers

55 and 56 that ride in the channnels 27 and 28 of the extrusion '21. The

transport rollers

55 and 56 may be made of nylon or other suitable material to give low friction operation. The cover plate 54 protects an imprinting roller 60'and protects the user from getting his fingers dirty from contact with the printing roller 60. It also supports the suspension system device for the printing roller 60.

As shown in FIG. 2, the machine 20 has an inner carriage assembly or inner frame 57 which may be supported by being screwed to the side plates 52and 53. This assembly or inner frame 57 has

sides

48 and 49 extending up parallel to and against the

side plates

52 and 53 of the carriage cover 51, and then has inset portions 58 and 59 leading horizontally inwardly on each side to upper vertical portions 61 and 62 that meet and are integral with a horizontal bridge 63. Each vertical portion 61, 62 may be provided with a vertically elongated slot 64 or 65. These elongated slots 64 and 65 hold a shaft 66 in a fixed fore-and-aft position relative to the carriage 50, and this shaft 66 is adjustable vertically in the slots 64 and 65. Vertical adjustment may be accomplished by the use of the

screws

67 and 68 which pass right through threaded openings in the shaft 66, as shown inFIG. 2, or it may be done in a different manner to be describ later. Accurate vertical adjustment of the shaft 66 enables it to be level or to be higher on one side than the other and enables it to be at various heights, to make up for discrepancies in other parts, thus achieving the adjustment feature referred to earlier.

The shaft 66 supports a yoke 70 so that it can swing freely forward and back, like a pendulum. The yoke 70, in turn, rotatably supports the printing roller 60. Thus,

the printing roller 60 may be mounted on a stationary shaft 71 which passes through a lower portion of two

arms

72 and 73 of the yoke 70 and is held by that loosely. The roller 60 may be provided with a relatively rigid cylindrical core and an outer covering of elastomer.

The

arms

72 and 73 are provided with a projection 74 that acts as a stop means, in combination with the covermember 51, the yoke swinging when the carriage 50 is moved forward, so that the stop means 74 of the

arms

72 and 73 engage a vertical portion 75 of the cover 51, and the printing roller 60 is then held down rigidly in its lowermost position and therefore is urged strongly towards the table 22; it therefore presses any intermediate parts such as a credit card with embossed figures and letters firmly against a manifold. When the carriage 50 is moved in'the other direction, there is no such engagement, for the

arms

72 and 73 of the yoke 70 swing away in the opposite direction, and the printing roller 60 does not normally even touch the paper or if it does, touches it only lightly so that no impression or blur is made.

As shown in FIG. 1, an anvil is completed by securing to the table portion 22 a pair of

plates

76 and 77, which are made removable in order to adjust from one type of embossed member to another. For example, one of these plates 76 may support an embossed metal mem-' ber usefully employed by the vendor to record its own name and address and its account number with the credit card firm; whereas the other plate 77 may be made of the proper thickness to accommodate a purchasers credit card. Normally the proprietors embossed plate is of metal and is of a different thickness from the plastic credit card, and therefore the two

plates

76 and 77 are made and installed separately and replaced separately. As a result, different thicknesses can readily be accommodated in manufacture and be available for use. If the thicknesses of the

plates

76 and 77 do not fully compensate, then the adjustment of the

screws

67 and 68 will do so.

With the

plates

76 and 77 in place on the table surface 22, the anvil is complete, and the proprietor secures to the roper plate 76 his own embossing plate. When a credit card is to be used, it is inserted into the guide 34 and is preferably guided also by a pair of

stop members

78 and 79 secured to the table 22. The manifold form is then placed over the credit card, as guided by the two

guide members

34 and 37, and by an engagement member 80 at each end, and then the carriage is moved over the manifold, achieving the embossment as the printing roller is pressed firmly down towards the anvil and then when (due to engagement of the extension 74 of the

arms

72 and 73 with the portion of the cover) the printing roller 60 ismoved in the opposite direction, to enable the vendor to take out the manifold and credit card, the printing roller 60 is automatically freed to preventthe taking of a second, or blurring impression.

As FIG. 2 shows, a storage box 81 may easily be secured to the bottom of the base extrusion 21, as by a slip fit, so that the vendors copies of the manifold may be stored there, as by slipping them in from one end.

The device of FIGS. 5 through 8 As stated before, it is sometimes advisable to use the credit cards on a variety of sizes of paper, and when this is done, the machine of FIGS. 5 to 8 is particularly suit able.

The machine 100 utilizes the extrusion 21 again but does so in a somewhat modified manner, in that two

slots

101 and 102 are provided, which are open at one end and closed at the opposite end. These two

slots

101 and 102 receive

elongated arm portions

103 and 104 of a yoke 105 supporting the roller 60, and the roller 60 is then located beneath the table'surface of the extrusion 21, where it will bear on a separate anvil member 110. This anvil member may comprise a single metal plate to which the extrusion 21 is pivoted by a pivot 111 as shown in FIG. 6, so that the machine 100 can be swung'open. The anvil member 110 may be provided with its own simple metal plates 112 and 113 (like the plates 76 and 77), such as may be required by the particular proprietor. the pivotal arrangement enables opening the machine, and it will be noted that the extrusion 21 in this instance may be closed by a bottom plate 114, preferably leaving a short windown area,l15 substantially equivalent to the area of the credit card to be used. Credit cards are almost always of the standard size, and it is therefore quite possibleto predict the amount of space they will take, whereas the amount of space the paper will take is relatively unpredictable. An end member 116 secured to the extrusion 21 in this instance is used as a handle and so may be provided with a handle loop 117 for use in opening and closure. The end member 116 and an opposite end member 118 close the

raceways

27 and 28 for the

transport rollers

55 and 56; the

end members

116 and 118 are secured to the extrusion 21 by screws 119. I

A carriage member 120 may be substantially the same as the carriage 50, and the

transport rollers

55 and 56 move as before in the

raceways

27 and 28 provided by the extrusion 21. Again, the printing roller 60 acts similarly to what it did before but is on a yoke 105 with

longer arms

103 and 104, which extend down through the

slots

101 and 102. The extrusion 21 helps in this instance by providing the center channel 40 which strengthens the extrusion 21 and also makes fastening easy in this location. The screws 119 thread themselves into the

channels

38, 39 and 40.

By way of example, a different sort of adjustment mechanism is shown in FIG. 8 in which screws 121 and 122 do not extend through a shaft 123, but in this instance abut against it and therefore force one end or the other down.

Except for the operation of swinging open the device I and except for the fact that the printing roller 60 is operating through the window 115, the operation here is substantially the same as that in the device already described. Modified adjustment means (FIGS. 9-12) FIGS. 9 and 10 show a modified assembly of parts of the carriage assembly, and FIGS. 11 and 12 show another modified assembly.

In FIGS. 9 and 10, the printing roller 60 and its shaft 71 are carried by a yoke 123 having arms 124 and 125 joined by' a bridge 126 lying to one side of the arms 124 and 125 near their upper end. A shaft 127 is held by members 128 and 129 of an inner frame 130 having a bridge 131 lying generally parallel to the bridge 126.

Screws

132 and 133 are threaded through the bridge 131 and form stops which the bridge 126 abuts when the yoke 123 and the printing roller 60 are swung to the rollers imprinting position.

In FIGS. 11 and 12 the printing roller 60 is carried on a shaft 135 which is adjustable in its yoke 136 or by set 1 screws 137. The yoke 136 has a bridge 140 lying near its lower end and to the rear thereof, and serving as a stop which engages stop screws 141 that are threaded through a carriage cover plate 142.
