1 Claim. (QI. lOl-269) This invention relates to a printing machine for show cards, and the like. It is particularly adaptable for printing advertising cards, show cards, and a variety of cards containing other type of information.

An object or the invention is to provide an improved printing machine for cards, and the like, in which the working parts are assembled for quicker action-more accurate` printing, and for longer life. Yet another object is to provide means for protecting the roller employed, for bracing an'd'locking together the manually-operated parts, forproviding better supports for the type blocks and more effective means for securing the cards to be printed upon the device. Other specific objects and advantages will appear as the specication proceeds.

The invention is illustrated, in a specific einbodiment, by the accompanying drawing, in which-y Y Figure 1 is a broken vertical sectional view of apparatus embodying my invention; Fig. 2, a transverse vsectional view; Fig. 3, an enlarged broken perspective view of the card-gripping mechanism shown; Fig. 4, a perspective assembly view ot the improved clamp structure; Fig.,5, a broken view in elevation of the clamp shown in position upon the type-supporting bar; and Fig. 6, a perspective view ci a portion of the type-supporting bar.

In the illustration given, Ii) designates a frame having its ends equipped with depending supports II. rThe supports II provide a longitudinal space below the main beam portion of the frame. Carried by the frame III is a bed plate I2. A rack I3 extends longitudinally of the frame along each side thereof, while a rack le extends along each end of the plate. A type-supporting bar I5 is provided with a notched or cut-away end portion I f5 adapted to extend into the notches Il of oppositely-disposed racks I3 or It. In the illustration given in Figs. 1 and 2, the bar I5 extends transversely of the plate I2 and engages the longitudinal racks I3.

Mounted upon the type-supporting bar I5 are the type members I8, which are preferably formed in the block-like shapes illustrated, having spaced leg portions I9 which straddle the type-supporting bar I5. The slot thus formed by the legs I9, as shown best in Fig. l, is accurately congurations 23 in the form of letters, chari acters, pictures, or portions thereof, asr required for the printing operation.

In order to lock the type bodies I8 accurately in position upon the type-supporting bar I5, I provide the following structure: The type bar I5 is, preferably, equipped with the saw-like notches 2I, as shown more clearly in Figs. r2, 5 and 6. Receiving the bar I5 is a clamp member 22, which may be formed of a sheet metal strip, as shown more clearly in Fig. fl. The member 22 is provided with a lower rectangular portion 23 snugly receiving the bar I5. The upper portion 24 is coiled to receive the compression spring 25.

Thefmember 22- is characterized by having an inwardly-turned neck portion l2t, which extends in a lnat plane almost across the top ofthe recvtangular portion 23. This nat wall or neckZB is extremely important in the locking `operation illustrated in Fig. 5, in that the fiat wall 25 provides a wide engagement with the notch 2| of the bar I5, and thus anchors the springA 25 iirmly against tilting in the supporting of the type I3.

In order to Support the board 2l, Whichis to be printed, well above the type IS prior to the iinal printing step, I provide the spacer'blocks 2S vwhich are similar to the type members I8 but which are equipped, at their tops, with short spring members 29 effective for holding the board E'I out of Contact with the type prior to the nal printing step, as shown more clearly in Fig. 1.

The frame I 0 `is equipped, o-n each side thereof, with a track portion 30. On either side of the frame is an end plate 3l. The end plate carries on its lower side a pair of ball bearing-equipped C' rollers 32, which bear against the underside of the track ange 3D. The end plates SI are provided with ball bearings 33 receiving a roller shaft 313, and the shaft 34 is provided, at each end, with a rigid roller 35 of steel, or other suitable material, resting upon the upper portion of the track 3Q. Extending between the rollers 35 on shaft 34 is an impression roller 3S, which may be resilient or provided with a resilient outer surface. The resilient roller 36 is protected by the rigid rollers 35, which roll upon the track Sil.

Securing thebottom ends of the end plates 3l is a cross rod 3l'. Securing the top portions of the end plates 3| is a tube 38, which also provides a handle for operating the structure.

At one end of the frame, there is provided a beam 3S having a curved end portion 4B, as shown more clearly in Fig. 3. A bar I-iI is provided with al rounded end 42 supported for rotation in the curved end d of member 39. A coil spring i3 has one end anchored within a recess in bar 4I and another end anchored within the curved end 40, as shown more clearly in Fig. 3. The spring serves to maintain the bar 4| normally in the position shown in Fig. 3. The bar 4| may -be equipped with a handle 44 for operating the same. The bar 4| may also be provided with a clamping bar 45 extending forwardly and provided with a downwardly-turned edge 46 adapted to engage one end of the card 21. 'Ihe bar 4| is preferably provided with a series of spaced clamping bars 45 for locking one end of the show card upon the supporting member 39, as shown more clearly in Fig. 1.

Operatz'mz meeting the type by the supporting springs 29.

The handle 38 is then grasped and pressed forwardly to draw the roller 35 over the card 21. The card is pressed down against the force of spring 29 and into contact with the type. I'he handle 44 may be then swung downwardly after the roller is removed from contact with the card to release the card and to permit it to be withdrawn. The printing operation may, if desired, be from either end of the machine.

In the arrangement of the type I8, the desired number of type members I8 may be placed upon the type supporting bar l5, and then locked securely in a group -by the clamps 2 2, as shown more clearly in Figs. 2 and 5. 4By providing inclined teeth about the notches 24' and by providing a transverse or flat neck 2B on the members 22, it is possible to obtain a graduated adjustment of pressure since the members 22 may be pressedV downwardly or upwardly within the inclined walls forming the notch 2| of bai'- I5 for exerting the'desired pressure.

While, in the foregoing speciiication. I have set forth one specific structure in considerable detail for the purpose of illustrating one embodiment of the invention, it will be understood that such details of structure may be varied Widely by those skilled in the art without departing from the spirit of my invention.

I claim:

In a printing machine for show cards and the like 'wherein the type members face upwardly in horizontal alignment, the improvement consisting of a type holder structure, comprising a typesupporting bar having the top thereof provided with a series of meeting notches with inwardly and downwardly inclined sides, at least one type member movably mounted on the top of said bar, and clamping members tiltably mounted on said bar on each side of said type members by means of a ring structure enclosing said bar, said clamping members having upwardly extending arms equipped with inwardly extending compression springs attached thereto and engaging the outer type members so that movement of said clamping members along said bar adjusts the clamping pressure exerted on said type members by said springs, said ring structure providing a transverse upper neck extending substantially the width of the sides of said notches seatable at various inclinations on the notched top surface of said Ibar being maintained in a selected position by engagement with an inclined side of one of said notches, whereby any desired pressure can be applied to hold said type members in correctly spaced relation.
