To ollbtuhom it wia/y concern: Y

Be 1t known that I, JOSEPH J. SAYRE, citi- Improvements in Irinting` Devices; and I` do hereby declare the followingto he a full, t 1e invention,

which it appertains to make and use the.

same. A

My' invention consists in thenovel featureshereinafter described reference being had to the accompanying drawing which illustrates one yform in which I have contemplated embodying my invention and said invention is fully disclosed` 1n the lollowing de seription and claims.y

Theobject of luy/invention is to provide improved( meansv for holding the movable "type lor printing boards, boxes, pasteboard,

` ete., on 'a cylinder press, in which the letters arey properly spaced and rigidly held in position without the use of screws or other removl In the drawings, I*

Fig. 3 isa similar view ol' aspacing bar, and Fig. i is a perspective view'oi1 one of the type, or printing blocks. ,Figi 5 is a partial sec .ional view on.

Fig.. 6 is a e'c-tion Online In carrying out my invention` I employ a curved holder ory chase, whichconsists of al backing plate A' preierabl of sheet steel curved so as to fitrthe cylinder of the press in which it is to be used, and provided at its oposite ends with :the lockingor retaining bars- AQA each of which is vpreferably made off-4 brass, `and provided with a portion a; Oven hanging the convex surface of the plate A, and ro'vided on its under side with a downwardly extending longitudinal rib a atgor adjacent to its inner edge,` and with a longitudinal groove a2 within said edge as shown clearly in thev drawings. The retaining bars A` A; may be secured` to the back plate A by",

Iiiif'azing, rivetingl or in any other desired manner. l,

upon the convex ,tacev ofthe lplate A and grooved on its eonyex side longitudinally as Patented sept. 29,1908.

l shown at b, and provided with inwardly projecting edges b. Ateach end the edges of the letter holder B are provided with notches b2. b2 to fit the bead c of thechase, and with lugs -b3,'b3 which lit the groove (L2 o'l` the chase.

C represents one of the movable type or letter blocks, which is (-.hamiered at top and bottom as shown to lprovide projections or 'flanges c c. These letter blocks or type can be readily inserted in the type holder-B, from either end, and set according to the matter to be printed in a particular lino, suitable spacing blocksoi variouswidths being provided as indicated at (Y, Fig. 1., winch correspond to the letter blocks C except for the impression surface, and these spacing blocks are used to space in the usual manner and to justi t'y the line at'each end with the inner edges of the notches b2 bz. The type holder is then inserted sldewise into the chase with the `beads o. fitting in the recesses bo4 and projections b fitting the groove c?, which parts lof the chase and Aletter holder interlock,A thus 'holding the letter holder in the chase, and `also securing the type and spacing blocks C,

C from longitudinal movement inthe type holder as will be readily seen. A number Of typeliolders oi varying widths and type of various heights and of any desired style may be provided, and a number of lines can be `set up in this manner in the chase.

In order to space the lines from each other,

when necessary and to space'the lines properly in respect tothe chase I provide a nurnber of space bars D, one of which is shown in Fig. 3. These bars arepreferably made of sheet steel and curved to fit upon the `convex face of the chase, and are further provided at each end with a transverse groove'or notch d and projection or rib d3 to interlock with the bead a and groove e of the chase.

These spacing bars are provided in varying widths so that by their use the line or type holders canl be vproperly spaced in the chase. Inorder-tofacihtate the handling of the chaseafter the type' holders` and spacing bars are-inserted, I prefer to provide the rchase with a retaining stri A2 or bead adjacent to one of itscurved e ges, to prevent the lateral movement of the bars but it isv not abs'olutely essentialy as the letter holders and s ace bars will he. held from movement by t 'e flanges ofthe cylinder of the press, when the 'chase is placed in operative positions.

cured to the cylinder in the usual manner,

.lOv The Mchase may beA placed upon and se.

and it will be noted that the type are held in proper position for'printing without the use of any screws or other detachable devices, the loosening of which, when they are used, is likely to cause annoyance and injury to the type or press.

. It is obvious that the particular form o'f the interlocking portions of the chase and bars, may be varied without departing from the spirit of my invention, of which the leading feature is the locking of the type in the type holders by placing the type holders in engagement with the chase. that the inner edges of the retaining bars A', A of the chase confine the type blocks against lateral movement, tween the flanges c c of the type blocks and the dovetailed grooves formed by the flanges l) of the letter holder, prevent the letter blocks from becon'iing disengaged therefrom.

While l have described and ilhistrated my invention as applied to a curved chase for a cylinder press, it is obvious that inlay make the chase, type holding bars and spacing bars flat and` use the same in a platen or other press having a. flat bed, if found desirable..

'hat .l claim and desire to secure b v lietters Patent iszl. 'llhe combination with the chase provided with oppositely disposed parallel retaining flanges ovehanging the face of' the chase, of a type holding bar provided with a longitudinal type 'receiving channel open at at last one of its ends, having lateral overhanging edges, and end portions constructed to engage the retaining flanges to simultaneously secure the type holding bar in the chase and close the open poi tion of' said channel to secure the type in the type. holding bar, substantially as described.

2. The combination with the chase provided with oppositely disposed parallel retaining flanges overhanging the face of the chase, of a'type holding bar provided with a longitudinal type receiving channel open at both ends having lateral overhanging edges, and having,r its end portions beyond said lateral overhanging edges constructed to engage the underside ofI said overhanging portions ol the retaining flanges, spacing bars having end portions constructed to engage the overhanging portions'of the retaining flanges, and type blocks having portions constr-ucted to engage the channel of the type bar, lthe retaining flanges closing the open ends of said type channel of the type holding bar when the parts are assembled, substantially as described.

3. The combination with a chase having parallel retaining flanges, a type holding bar having a longitudinal type holding channel open at at least one of its ends, and end portions beyond the channeled portions constructed to interlock with the said retaining lt is obvious and the engagement -be`"' flanges, said retaining flanges having portions closing the open end or ends ofthe type holdinfY channel, when the type holding bar is place in engagement therewith, substantially as described.

5. The combination with a chase compris inga curved plate provided with opposite rctaining flanges` extending over the convex surface of said plate, of a curved type holding bar, having a longitudinal type holding channel open at its ends, and provided with ovcrhanging lateral portions terminating at a distance from the ends of said bar, and having its end portions beyond sai-d overhanging lateral portions constructed to pass under the said retaining flanges, said retaining flanges closing the said type holding channel at each end when the type holding bar is placed in engagement therewith, curved spacing bars having their end portions constructed to engage said retaining flanges, and type blocks having oppositely disposed projecting portions to engage the channel of said type holding bar, substany tially as described.

6. The combination with a chase comprising a plate provided with opposite retaining bars having portions extending over the face ol the plate and provided on the under side thereof with a longitudinal bead at its inner edge and a longitudinal recess within said bead, of' a type holding bar having a longitudinal type holding channel open at its ends and provided with overhanging lateral portions terminating at a distance from the ends of said bar, and having its end portions provided beyond said overhanging lateral portions with notches to fit the said bead, and with projections to fit the groove of said retaining bars, said retaining bars closing the type holding channel at each end when the type holding bar is placed in engagement therewith, substantially as described.

In testimony whereof I aflix my signature, in the presence of two witnesses.
