14 Claims.

This invention relates to printing machines, the

object being to provide a simple and inexpensively constructed printing machine which includes a bed plate on which the type are to be positioned, a flexible cover, a printing roller adapted to be moved across the cover member to produce the printing impression, and guide means enabling an operator to predeterm be printed relative to t inedly position the card to he type.

A further object and feature of the invention is to provide a light flexible sheet metal bed of simplified construction w ith non-ilexible side rails providing runners supporting the printing roller.

A further and prim ary object and feature of the invention is to provide a printing machine in which type are supported in place without necessity of locking the same in a form.

Previously, the practice has been to set the type in a form and lock the same in position and the bed of the machine is so constructed as to hold the locked form in a predetermined position. By our invention, a sheet of appropriate material is coated with a composition, such for instance as beeswax, to provide a surface semiadhesive in character on which the operator may place the type in any desired relation, that is, a

line may be arranged in a curve, in a straight line, or other desired form and by placing the type one by one with a little pressure on the prepared sheet of material, they adhere thereto suiiiciently to permit the inking of the type with an inking roller without displacing the same thereon.

In fact. by each inking and printing operation by the printing roller, the type are caused to more iirmly adhere to the adhesive surface. By such an arrangement, persons of little or no knowledge of setting of type in the ordinary way are enabled to use the machine and further than this, the total cost of the machine is reduced, that is,.the form is not only dispensed with but the machine work necessary to pro otherwise securing the pensed with.

vide means for locking or form in the bed is also dis- These several objects-and novel features of the invention are hereinafter more fully described and claimed, and the preferred form of construction of a printing machine embodying our invention is shown in the accompanying drawings in whichprinting machine.

Fig. 2.is a plan view of a part thereof on an enlarged scale.

Fig. 3 is a cross sec on line 3-3 of Fig. 2.

tion of the machine taken (Cl. lOl-269) Fig. 4 is a detail partially in section showing '9 the type in position and the use of the inking roller in relation. thereto.

Fig. 5 is an enlarged'section taken on line 5-5 of Fig. 3 showing the guide clips and arm for supporting a sheet to be printed;

Fig. 6'is a similar view showing the manner of attachment of the clips.

Fig. 7 is a section of a portion of the bed and cover member showing the type in place.

Fig. 8` is a similar View showing the impression rollers in the act of printing.

Fig. 9 is a plan view showing the preferred form of diagram on the adhesive sheet.

Fig. l0 is a sectional View on line 10--10 or Fig. 9 showing part of the adhesive sheet.

The printing machine is shown in Fig. 1 and in this View it will be seen that the bed platev consists of a sheet of metal 1 the ends of which are downturned and return bent as at 2 to provide feet spacing the plate above the surface of a table or other support on which the printing machine is placed for use. The bed plate l has secured thereto side rails 3 and 4` o1' U form and these in turn are spaced from the bed plate 1 by longitudinal strips 5 less in width than the channel rails 3. The inner edges of the rails are thus spaced from the bed plate'providing a recess for the edge portions of a more or less ccmpressible or resilient sheet or pad 6 and on this sheet is placed semi-adhesive type holder sheet '7 hereinafter more fully described, it having its edge portions inserted beneath the inner projecting edges of the channels and fits therein suiiiciently tightly to hold the edges of the sheet 'T from displacement in the inliing and printing operation.

It will be understood from Figs. l, 2 and 3 that theside rail 3 is provided with several lugs 8, 8, 8 which are apertured to receive a hinge rod 9. A flexible cover l0, preferably of sheet metal, is formed with ears-1l, 12 and 13 connected with the rod whereby the cover is secured in hinged relation with the bed plate. The rod 9 also has blocks 1414 thereon that are slidable longitudinally of the rod and' to these blocks is respectively-attached the guide bars l5. The guide bars at the free ends-are each provided with a latchv member 16 preferably spring-actuated to engage over the free edge ofthe cover 10- in the position of parts shown in Fig. 3. The arms 15, asshown in Fig. 3, particularly at the free end when unattachedto the cover by the spring dog 16 normally rest on the upperv edge of the channel 3 and provide means for supporting a card over iov lio

the face of the type that are set on the bed plate as hereinafter stated. The bars 15 are preferably formed of spring steel and normally are slightly bowed and when placed over the bed the upper surface is slightly above the type faces. The cover 10 is likewise transversely bowed. Thus the card to be printed is secured between the cover and bars by pressure when the clips 16 are engaged over the edge of the cover as shown in Fig. 3.

A special feature of this invention consists in the adhesive or semi-adhesive sheet '7 which is preferably provided with lines, such for instance as the diagram shown by the rectangles i7 in Fig. 1, and is coated with a waxy composition on which the type may be set. The coating for the sheet may be composed of ingredients in the following approximate proportions viz: one pound beeswax, one-half pound resin and one-hair pound glycerin, or one pound beeswax to one pound commercial belt dressing; both of which have been found adaptable for the purpose. Other ingredients may be found equally desirable. The sheet to be coated is preferably of paper as indicated in Fig. 10 and the type, which are preierably of wood, are individually set in place by hand, a little pressure being applied thereto to cause the type to adhere to the waxed sheet.

Fig. 2 indicates type set in a straight line on the sheet '7 but, due to the manner of securing the type in place, they may be set in any desired arrangement and the lines 17 are merely guide lines to enable the operator to line up the type sui'liciently accurately to make a straight line if desired or to position the printing face of the typeV relative thereto. Only one form of diagram is shown by the lines 17 but it is to be understood that a diagram or guide means of any shape or form may be utilized on the sheet as may be desired. The wax or other adhesive or semi-adhesive matter applied to the sheet should be more or less transparent in character so that the diagram or guide is visible in the coated sheet.

When the type have been set as indicated, the bars 15 are released from the cover and laid over the bed at opposite ends of the set type and out of position to contact the same and in such position they provide supports for the card or sheet to be printed. It will be observed from Figs. 1, 3, 7 and 8 that the bars 15 are so positioned that the upper surface is slightly above the face of the type permitting the placing of a card 13 thereon outv of contact with the type face at this time. These bars 15 are oi metal and are flexible in character as is also the cover member 10 which, after the placing of the card on the bars, is laid over the card and engaged with the spring clips or latches 16 at the ends of the arms. Preferably, the bars are provided with spring clips 19, 19 thereon each bar being preferably provided with two clips which are shown in section in Figs. 5 and 6. These are simply of spring sheet metal and, as shown in Fig. 6, by pressing on the clip toward the bar they may be snapped in place and, due to the bars having beveled edges as shown, the ends of these clips engage thereover and by pressing on the clip to slightly release the same, are slidable longitudinally Yof the bar. Thus, in placing the bars in position to support a card for printing the clips may be positioned in relationship to the guide diagram so that the edge of the sheet to be printed may be properly positioned relative to the type face.

The diagram on the adhesive sheet 7 also provides a guide for the operator in positioning the same. These clips extend slightly below the under surface of the bar when positioned and iorm a further guide for the operator in position-v` clamps the sheet 18 to be printed between the bars and the cover plate and in this position the sheet is still slightly spaced from the printing face of the type as shown in Fig. 7.

The bed plate is longer than the cover member as will be seen in Fig. 1 and in the space between the right hand end of the cover member and the end of the plate 1 providing the bed is positioned the printing roller. This consists of an upper roller 20 and a lower roller 21 rotatably supported in end frames 22 and 23 respectively. A bar 24 providing a hand grip is also secured to the end frame to enable the operator to pull the rollers across the 'bed plate when the cover is positioned over the type. These end plates, as will be understood more clearly from Fig. 2, have foot-like portions thereof resting on the outer flange of the channel rails and the end plates each carry rollers 25, 25 engaging the side face of the outer flange of the respective railsV preventing any material lateral movement of the roller frame.

This character of printing roller is shown in the pending application of Charles M. Lamb, Serial No. 439,794 filed March 28, 193e, and operates in the saine manner as therein described, it being provided with a means consisting of an arm 26 carrying a spring dog 27 for engaging the notches 28 on the end frame 23. This dog and lever permit an adjustment of the spacing apart of the rollers 2O and 2l and determines the pressure to be applied in the printing operation. It will be seen in Fig. 2 that the length of the upper pressure roller 2O is less than the distance between the upper faces of the two side rails 3. The rollers and frames are also so mounted as to permit of vertical movement relative to the channel members to enable the same to ride over the cover member as will be understood from the following.

When the cover is down, which is the'position of the parts shown in Figs. 3, 7 and 8, the roller frame is drawn across the machine by the hand bar 24. rPhe rollers thus progressively press the cover and the card 1S thereon to printing contact with the face of the type and, after drawing the rollers once or twice across the cover as stated, the printing rollers are withdrawn to the position shown in Fig. 2 and the cover raised thereby raising the printed sheet from the type. The bars are then released by releasing the spring dogs 16 and the bars are laid down over the bed for the positioning of the next sheet to be printed. The printed sheet is removed after the bars have been released from the cover.

Another feature of the invention is shown in Fig. 1 wherein the type side of the cover is provided with a diagram corresponding more or less to the diagram on the adhesive sheet '7 and thus the sheet to be printed may be placed directly on the cover and secured by the bars and then laid over the type or the clips 19 may be properly positioned when the bars are in the position shown in Fig. 1 whereupon on laying the same downwardly over the bed they are similarly positioned For this use of the device the sheet 7 should be positioned on the bed plate With the diagram thereon substantially in alignment with the diagram on the cover as will be readily understood.

A special feature of the invention is in the provision of the sheet having the adhesive surface on which the type are positioned and these, as before stated, are placed on the sheet manually and a little pressure applied thereto to cause the same to adhere and retain their place sufficiently rigidly to permit inking thereof which is accomplished by means of the inking roller 30 shown in Fig. 4. This roller is provided with a handle 3l to permit of its manipulation and may be of any approved form. By this arrangement for setting type the facility and speed with which the type may be positioned is greater than is secured by locking the type in a form and subsequently securing the form on the bed plate as is the usual practice.

The expense of the apparatus is also reduced and the machine is made very light in weight by forming the bed plate and the end standards of sheet metal more or less flexible in character. By securing the side rails thereto a practically nonflexible runway for the pressure rollers is provided as heretofore described. With a flexible bed plate a flexible cover the rollers, by being spaced a predetermined distance apart, apply pressure to the type and hold the bed from flexing at the line of application of pressure.

It is further to be understood that preferably the sheet to be coated is of paper or cardboard and thus is inexpensive and may be discarded and another sheet used in its place as soon as the coating becomes thinned or non-adhesive through use. The invention in respect to the type holding means is not conned to the use of a paper or fibrous sheet as any sheet of material adaptable for such use may be employed, as for instance tin er celluloid. Furthermore, the coated element need not be in sheet form inasmuch as the invention in its broad aspect consists in coating the type supporting surface with an adhesive or semiadhesive material.

We are aware that the bases of type have been coated with an adhesive material but this is inconvenient and expensive as the coating deteriorates through use and the type then require recoating one by one by hand. By our improved arrangement such labor is dispensed with and as a quantity of coated sheets are usually sold with the machine and others supplied as the purchaser may need, a clean and fresh adhesive surface is continuously available for use in the setting of type.

It will be observed from the foregoing that by our improved construction a light portable printing device is secured that is of inexpensive construction, and further that we secure a printing machine in which even persons unfamiliar with the printers art set the type and produce a neatly appearing printed sheet. Thus a machine is secured that is very convenient for the use of merchants for instance where display cards are required in conjunction with displayed merchandise at considerably less cost than through use of the ordinary printing machine with skilled typesetters and that the various objects of the invention are secured by the construction described.
