The present invention is in the nature of an improvement on that set forth in my application for United States Letters Pat ent No. 172,317, filed September 8, 1903.

In carrying out the present invention, I provide a chase or frame which may be conveniently formed of three integral sides 1 and a separate side 2. The integral portion constitutes one side and two ends and the .separate portion 2, constitutes the other side.

The side 2 is secured to the other portion 1 :by means of screws 3-3 tapped into threaded sockets l-l; dowel pins 55 are provided to accurately position the side 2. Along the inner sides of the frame or chase I so formed are arranged notched strips 6-6 having notches 7 to receive the ends of the bars B. The strip 6 is secured to the portion 1 of chase by means of screws (S -43". The notched strip (i is loosely mounted in the other side of the chase guided upon pins 88 in the inner edge of the strip 2. The notched strip 6* has spring connections with the side Q-by means of tension'springs 9-9 which are received in openings or housings 10-10 in the side 2. One end of each of these springs is secured to the strip (i their other ends being secured to screw plugs or caps 9 The action of these springs, as Will be seen, is to withdraw the strip 6 away from the ends of the bars. The strip 6 is moved inwardly toward the ends of the bars to clamp the samein position by means of cams 1ll1 pivotallymounted at 12 12 in the side 2. Thesecarns are caused to work in unison 'by means of a link 13 which connects them together. One of the cams is formed with a handle or lever 14; by means of which the cams are operated. A spring latch 15 is mounted near the corner of the chase adjacent lever 14 to hold the chasein locked or clamped position. A stop 15 is provided to limit the throw of lever l l.

In the two longitudinal sides of the chase are mounted bars or strips 17 provided in their upper faces with teeth or pins 18. said strips 17 being received in longitudinal channels or grooves 16. The teeth or pins 18 in said strips are so arranged as to register in line with the bars 13, each pin being opposite the end of a bar, and preferably in line with its longitudinal center. These pins form positioning or locating means for the lines of composition to be transferred to the barsthe transfer sheet being provided with perforations which bear the same relation to the lines of composition to be trans ferred to the bars as these pins 18 bear to the bars. Strips 17 are supported in their grooves 16 upon springs 22--22 which tend to force said strips upwardly, as shown in Fig. 5. In the ends of said strips are slots 19 through which pass pins 20 having screw parts 21 by which they are secured in the sides of the chase, said slots being of proper length to limit the movement of the strips. Near the ends of said strips on their outer side are formed steps 2%, 25 in position to be engaged by the ends of spring bolts 26, said bolts being suitably mounted in the side portions of the chase and having springs 27 tending to press said bolts inwardly to engage said steps 24-25. The ends of said bolts are formed with knurled portions 28 to form secure finger holds. The action of the bolts and the steps is to hold the strips 17 in depressed positions as illustrated in Figs. 6 and 7, for a purpose hereinafter described. A longitudinal bar 30 is detachably arranged across the opening in the chase to prevent the bars from falling through when the chase is lifted or carried, the bars being formed with a notch or cut 39 in their rear faces to receive said bar, it being understood that said notch fits loosely. over the bar as clearly shown in the sectional view, Fig. 2.

I may employ various forms of bars 13 and notches 7, it being understood that the bars B are so formed as to cooperate with the notches to be accurately positioned with relation to the pins 18 or equivalent registering means, when the lever let is operated.

To this end I provide notches and bars of such a form that the bars will automatically find their notches when'the chase is locked being guided therein by the shape of the notches and of the ends of the bars. In Fig. 8 I have shown a form of bar for cooperating with the form of notch shown in Fig. 1, the bar being provided with beveled or tapering faces 31. Other forms of bars may be employed for this purpose as shown for instance in Figs. 91(), in which the edge of the bar formed by the meeting of beveled faces 31 is chamfered or truncated to form flat ends 33, see Fig. 11. In Figs. 12, 13 and 14 is shown another form of bar and notch in which the ends and faces are tapered or beveled and in which is provided a shoulder or abutment 34. In Figs. 15, 16 and 17 is shown another form of bar and notch, the end of the bar being formed with a tongue 35 inserted therein to cooperate with the form of notch shown in Figs. 15 and 16. the corners of the notches and the tongue being beveled or chamfered as shown. Still another form of notch and bar is shown in Figs. 18 and 19,-the notch being formed by small tongues or projections 38 let into the side pieces 6-6 and receiving between them the ends of the bar shown in Fig. 19, the corners of the tongues or projections 38 and also the corners of the bar being chamfered as indicated by the nume al 37, Figs. 18 and 19.

IVith the form of chase herein illustrated and described bars of different widths may be used as is shown in Figs. 9 and 10, Fig. 10 showing a narrower bar than Fig. 9, see also and compare Figs. 12, and 13 and Figs. 15 and 16. This is for the purpose of accommodating different type sizes, for instance, 6 point, 7 point, 8 point, etc.

It will be understood that the transfer is made from a transfer sheet, such for instance as is shown in Fig. 20, the matter being in the case of letter press usually in justified lines as appears clearly from Fig. 26 of the drawings, upon the bars after they are locked in position in the chase. In order to accurately register the lines of composition on the transfer sheet with the bars, said sheet is provided with positioning or locating marks bearing the same relation to the lines of composition as the pins 18 bear to the bars. In Fig. 20 1 have shown a sheet provided with these marks in the form of perforations 50. lVhen the transfer is made the perforations 50 are placed over the pins 18 and thus the lines of impression are accurately placed each upon a separate bar. These perforations 50 may either be perforations specially made for this purpose either before or during the impression of the composition upon the transfer sheet; or perforations 50 which represent the sprocket feed perforations, such as are employed in automatic typographic apparatus in which the composition is impressed upon the transfer sheet said sheet being fed by means of the holes 50 a line space at a time, see Fig. 32. Instead of perforations, the positioning or locating means may be in the form of marks such as cross marks 5l52, shown in Fig. 21 which are printed or otherwise formed on the back of the transfer sheet while the same is receiving the composition. Vhen this character of locating or position means is employed the strips 17 and pins 18 are di pensed with and the face of the chase is marked with cross marks 5354:, as shown in Fig. 22, corresponding to marks 51, 52 which bear the same relation to the bars as marks 51 and 52 bear to lines of composition. When the transfer is to be made to the bars, they are securely locked in the chase, by means of the locking means described.

In order to protect the notches or recesses 7 and working parts of the chase, such as the strips 17 and the movable side 2 with its cams, etc., during the process of making the transfer, 1 provide a plate 47, shown in Fig. 23, of the same form and size as the chase with a central opening 48 to expose the bars 13 therethrough. This plate 47 is made of the same material as the bars so as to present the uniform character of surface there-' with. In the plate 47 are arranged openings 49 to receive the strips 17 which project upwardly therethrough, the pins or teeth 18 projecting above the surface of the plate 47.

The bars B are formed of a slightly greater height than the chase, as clearly shown in Fig. 2 and are provided with shoulders 32-82 see Figs. 8, 11, 14 and 17, so that the portions of the bars which project above the surface of the chase are rectangular and closely fit against the sides of the openings 48 of the plate 47 when the same is placed on the chase. The thickness of plate 47 is equal. to the depth of the shoulder 32 so that when the plate 47 is placed in position, the surface of the bars is in the same plane as the upper surface of plate 47.

Fig. 25, a, shows the relative position of plate 47 in place, with the teeth 18 projecting above the surface of the plate. The transfer sheet may now be applied and positioned by means of the locating marks or perforations. In making the transfer, the transfer sheet is pressed closely in contact with the bars. The presser passing over the teeth 18 in strips 17 depresses said strips until they are caught or held in depressed position by thespring bolts 26 engaging the first step 25, see Fig. 7. Plate 47 may now be removed, after cutting the transfer sheet around the opening 48; and plate 55, see Fig. 24, is then placed upon the chase and over the bars; this plate being provided with a siinilar opening to through which the surface of the bars appear. Plate 55 is of the same material as the bars themselves and forms therewith a uniform planographic surface. This plate 55 has no opening to receive the strip 17, these strips being covered or protected by the plate so that the water, gum, acids and other fluids and materials employed in making the transfer to the bars and in fixing the impressions thereon are prevented from finding their way into any portions of the chase where they might do injury by causing corrosion and preventing the working of the parts. When this plate 55 is placed on the chase over the bars it depresses strips 17 which are immediately caught and held in depressed position by bolts 26 engaging notches 25, see Figs. 6 and 25, b. Plates 4:7 and 55 are provided with pins 55 to register with holes 1 in the chase so that said plates may be rapidly and accurately positioned.

An important feature of advantage possessed by my invention consists in the arrangement of the notches 7 which receive the ends of the bars at such a distance apart that spaces S are left between adjacent bars. These spaces serve an important purpose, viz: They permit the fluids and other materials used in transferring and rolling up the design on the bars to escape. Where the bars are brought close together when a design is being transferred thereon, the water and other fluids and materials used to roll up the design or to bring the surface into condition to receive and hold the transfer find their way into the interstices or joints between the bars and will in the treatment of the bars and rolling up of the design subsequently ooze up again on to the surface and spread over the same and over the design or impressions thereon and prevent them from properly taking ink, thus causing imperfect and partly obliterated impressions. With spaces S between the bars there is no tendency for this defect and imperfection to occur. The fluids, etc., find free escape from between the bars and what slight film may remain on the sides of the bars will rapidly evaporate or may be removed by wiping if desired. Thus perfect impressions are insured.

The chase above described is employed for the transfer of the composition or design to the bars. After the composition or design has been fixed upon the bars, a proof impression may be taken, which proof may be read and corrected and any desired alterations may be made in accordance with the corrected proof by removing bars and substituting other bars in their place with the corrected matter thereon; or the bars may be transposed or rearranged in accordance with the corrected proof; or additional bars added. The chase is then unlocked and strip 30 is removed by taking out screws 0 -30 and the bars in their proper order are, in accordance with the corrected proof, ar ranged in a chase 40, see Fig. 26, of ordinary form and construction and without the notches for positioning the bars. The bars are secured in this chase by the ordinary wedges or quoins 41 being alined in column by their ends. The leading or line spacing of the composition may be varied in this chase as desired and as shown in Fig. 26 by the insertion of leads between the bars. The upper bars shown in said figure are arranged to give double leading; the bars in the middle portion of said figure are shown arranged to give single leading and the bars in the lower portion are shown arranged to give what is termed solid matter;

Instead of the chase shown in Fig. 26, I prefer to employ a chase of the character shown in Figs. 27, 29 and 30 in which the bars are alined in column al'inement by means of a strip 42, see Fig.31, having beveled portions 43, l4 for engaging similarly under-cut portions 45, 4:5 in said chase. This bar 49 is of a width along its intermediate portion to fit accurately the cuts 39 in the lower faces of the bars B, as clearly shown in Fig. 29. Thus the bars B are alined in column position by means of said strip 42. An end wedge 41 is employed to securely hold the bars in the chase. From the bars as arranged in this chase a retransfer is taken which is then laid down upon a planographic printing plate of the ordinary and memes:

well known construction, such as a flexible metallic plate which may be secured in well known manner on the form cylinder of an ordinary rotary press and as many impressions taken therefrom as may be required.

In taking the retransfer from the chase, shown in Fig. 27, a plate 55 is employed to form a uniform and level planographic surface with the bars as described in connection with the chase shown in Figs. 1 and 2. This plate protects the ends of the bars from the fluids, etc., employed in making the retransfer, as clearly shown in Fig. 30.
