This invention relates to-improvements in forms for holding type or matrices for use in connection with printing and embossing presses, andwin platens for use in combination therewith.

The said invention provides an arrangement of bars between which the type or matrices are held and means for locking the bars together in pairs so as to hold the type between them, the means for locking together the bars being also employed for holding the type or matrices against longitudinal dis placement in the bars. The bars are provided with means whereby they can be supported on frame parts which may, ii"? desired, form part of or be attached to a platen on which the paper, cardboard or other material to beprinted upon or embossed is supported while the type are subjected to pressure to make. an imprint or impression thereon.

V As shown in Fi ures 1, 2 and 3, platen 10. is provided with lateral'flan'ges 11. A saddle bar12 is attached to each flan'gell by'screws or pins 13 passing through slots 14 in thebar 12 allowing a rising and falling movement of the bar relatively to the corresponding flange (Figure 1) but preventing relative longitudinal movement of these parts. A slide bar 15 held between the flange ll and bar 12 is provided with pins or screws 16 passing through slots 17 in the saddle bar so that whilst a limited longitudinal move ment of the slide bar relatively to the flange l1 and saddle bar 12 is permitted the slide bar and saddle bar rise and fall together. The slide bar 15 has oblique slots 18 formed therein through which the screws or pins 13 pass.

When the slide bar 15 is moved to the right from theposition in which it is shown in Figure 3, the slots 18 riding on the screws or pins 13 lift this bar and also raise the saddle bar 12 through the pins or screws 16 travelling in the slotsl17. The slide bars on opposite sides of the platen are connected by a handle bar 19 by which the slide bars can be moved simultaneously and thumb pieces or lugs 20, are provided on the saddle bars for conveniently holding the latter whilst the slide bars-are moved, relatively thereto, more especially when the slide bars are being returned to the position in which they are shown in Figure 1.

Saddle pieces 21 are attached to the saddle bars, for example, by screws 22, or may be 90 formed integrally with these bars, these saddle pieces preferably being formed to fit over the flanges 11 and thus assist in maintaining the bars 12, 15 attached to the flanges. The saddle pieces 21 are formed with apertures 28 in which rods or rails 24 are mounted. These rods or rails may be of circular, oval or other cross section but are preferably of'rectangular cross section as shown. The rails 24 have grooves 24a formed therein which slide on the saddle pieces as the rails are inserted in the apertures 23 and prevent longitudinal displacement. The grooves 24a are of the nature of saw cuts of a width equal to the thickness of the saddle pieces 21, as shown in Figure 3, and the depth of the grooves is apparent from a consideration of Figure 1 in which the bottoms of the grooves areindicated in broken lines which also indicate'the edges of the apertures 23. The no grooves in different faces of the rails can be made of different depths so that by inverte ing the rail the height at which it is supported above the saddle bar can be altered.

Type or matrix supporting bars are suspended from the rails 24 by'hooks or clips 26 preferably of tubular form threaded on the railsand slidable thereon to difierent positions. These hooks 01' clips may be retained in any positions to which they may be adjusted by frictional engagement of the clips withthe rail, or 'set screws may be provided to clamp them in the desired positions with type or matrices held between pairs of supporting bars 25. Thus a number of lines of type or matrices may be carried by the rails 24 assembled together for use in a press.

The type or matrices 27 are provided with slots 28', Figures i and 5, to engage ribs 29 on the supporting bars 25, the slots being somewhat wider than the ribs, but it is evident that shoulders orribs may be provided on the typeor matrices to engage-in grooves or slots'provided'in the bars. Although the space between the lowerwall of the slot-28 and the underside of the rib cannot be seen in Figure 7, since in that figure they are concealed bythe clip extension 31, the difference- 7 of size oflthe slot and 'ribwill'be noted upon comparison of-Figure 5 withFigurelO. The

' type or matrices held between a pair of supportingflbars are spaced apart for example,

in groups forming words, and held against longitudinal displacement in the supporting bars by distance pieces which may simply rest on the supporting bars ormay be clipped thereto,lthese distance pieces being also adapted, if desired, to hold the supporting bars properly spaced apart and locked together inpairs. Thus,- a line of type or matrices can be set up between two supporting bars and a distance piece' clipped to the said bars at each end of this line to prevent endrwiseidisplacement of the type whilst they simultaneously preventseparation of the bars so that ,a pa-ir of the latter with type or 'iatrices set up between them can be moved from place to place without disturbing the order, spacing or position of thetype By reasonof theribs29 engaging in the slots 28,

. the supporting bars can even be inverted removed therefromas may be required, and

without the type or-matrices becoming displaced; Also a'number of lines of type or matricesmay be kept set up in supporting bars which can be threaded onto rails or groups of lines thus set. up-can be held as- 7 semb'led on rails constituting a forme which can. be mounted in the saddlepieces "or detached therefrom 1 and carried from place to placewithout disturbing the assembly.

An edge viewcfa suitable form of distance piece 30 provided withlclips' at eachen'dissh'ownin Figures 6 and 7 comprising ;a,body;of a suitable length to-be inserted be-- tween the supporting bars 25. At its ends this body is provided with thin extensions 31 which, when the distance piece is in use, rest on the bars 25, said extensions being preferably bent to conform to the shape of the flanged bars as shown. In addition each end of the distance piece can be provided with a spring clip 32 which, when in use, is pressed against the side of the bar opposite to that a with which the corresponding extension 31 is in contact; These distance pieces provided withclips may also serve .to' hold together pairs of supporting bars 25' when the latter are removed from the rails ofthe form.

The distance pieces may be arrangedto rest onthe ribs 29 or between the ribs of adjacent-bars. They may be provided with clips at both ends for engagement with thebars '25, or each distance piece may. have a clip at one end only. As the separation of the bars 25 can be determined by thehooks or clips 26 clamped to the rails 24, the distance pieces can be made like the type or matrices 27 with slots to engage the ribs 29; Another suitable form of distance piece 30a is shown in Figures 8 and 9 made from a flat plate slotted at the ends with parts 30?) bent oppositely outwardly. This plate maybe of a resilient material, the parts 306 acting as clips gripping the'ribs 29. e v I 7 Short clips 32a, shown in Figures Y10 and 11 may be pressed on to the ribs 29 to preventmovement of the type or matrices longitudinally on these ribs.

The construction hereinabove described with reference to Figures 1, 2 and 3 provides for supporting the bars 25 in positions parallel tothe handle bar 19 but means may be provided for arranging the lines of type or matrices at right angles to the said handie bar. .As shown in Figures 12, 13 and 14 rails 33 are suspended on hooks or clips34 mounted. on the ends ofthe' rails 24but it is obviousthat therails 33 may be mounted directly on the saddle bars 12. The rails 33 extend parallel to the handle bar 19 and support type or matrix supporting bars 35 by .means ofhooks 36, 37. The hook 36 is made to embrace more than two sides of the cor- 7 allowing the type or matrices to be'used with the operative faces thereof opposite to. the platen, the card or paper to be operated-upon being placed on the platen beneath the type or matrices, or the type or matrices vmay be atlie lie

ranged with their operative faces uppermost,

I the card or paper then being placed thereon between these faces and the movable rain of the press.

Thus, if the rails 24 are inserted with the appropriate grooves 24a slid on to the saddle pieces 21, the operative faces of the type or matrices, when the saddle bars 12 are in their lowermost position, are out of contact with the platen, and when the saddle bars are raised by drawing out the slide bars 15 the type or matrices are carried further away from the platen to allow a card to be placed on the platen or removed therefrom. If it is desired to place the card above the t 1 3e or matrices the latter are set up in the supporting bars with their operative faces uppermost and the rails 24 are put in such a position in the saddle pieces that the grooves which are then 7 lowermost allow the rails to be lowered so that the backs of the type or matrices rest on the platen.
