READILY-CHANGEABLE TYPE-FORM.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed April 7, 1913. Serial No. 759,556.

To all whom it may concern Be it known that I, NILLIAM R. ALLEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and usefulv Improvement in Readily-Changeable Type-Forms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a simple and effective means for holding type matter, (line slugs, logotypes or individual type) locked in a form so that it may be printed, but in such a manner that any line or portion of the form may be quickly and easily removed and another put in place of it.

My invention is well adapted for use with ofiice printing machinery of the type known as multigraph, though its use is not limited thereto.

It consists of a holder having a pocket or trough in which the type or printing members may stand, means engaging an end of the spacers between the type lines for holding them approximately in place whenthe ty e are removed from between them and a suitable clamp to lock both the spacers and the type while printing.

The invention is hereinafter more fully explained and other features of it herein set forth.

Referring to the drawings, Figure 1 is an end view of a printing drum, showing a trough in which the type are held, and the path of the type and the relative position of a suitable platen; Fig. 2 is a plan of a portion of the drum showing the type matter locked in place; Fig. 3 is a section of one end of the pocket or trough taken substan tially on the line 3-3 of Fig. 1; Fig. 4 is a detail of one of the clamping members; and- Fig. 5 is an end elevation on an enlarged scale of the type showing the wedge shape of the spacings between the lines.

5 in the drawings indicates a removable segment such as is used on the multigraph printing device and is shown as held in position on rods 6 and 7 by means of a clamping spring 8 which hooks over the central shaft 9. This segment and clamping means are of the type usually used on the multigraph but my device is not limited to its use with these adjuncts.

10 indicates a trough or pocket formed in the drum, having radial sides and a curved bottom concentric with the shaft 9, and of such a depth that standard type in the form of line slugs, logotypes or individual type may stand thereon and project at a suitable distance for printing. The amount of this projection is such that the printing surface of the type 12 is the same distance from the center of the shaft 9 as the type 14, which are shown as short type having grooves on their opposite sides engaged by rails 15 mounted on the periphery of the segment 5. The type 12 are of the usual form with parallel sides and are properly spaced in the pocket 10 by wedge shaped spacers 17, the taper of which may be varied to suit different widths of type used. The pocket 10 is shown as extending substantially the full length of the segment 5 and the type matter 12 is locked on the sides by means of set screws 19 hearing at their inner ends against a strip 20, standing in the pocket against the first line of type. The segment 5 is cut away at 22 so that the heads of the set screws 19 will not project materially beyond the segment.

The means for holding the lines of type 12 at the ends are two arcual clamps 24 and 25 which may be conveniently made of a flat metal strip, somewhat longer than the width side of the strip bent first downwardly, at

28, and then inwardly at 29, toward the type substantially parallel with the upper portion of the strip, indicated in Fig. 3 at 24. The upper portion of this clamp is adapted to abut the ends of the lines of type. The spacers are made longer than the lines of type, project beyond the lines a little at each end and stand under the edge 31 of these clamps.- This holds the spacers from moving outwardly and subsequently holds the type in place. The ends of these spacers are engaged by suitable elastic material 30 held in the U-shaped portion of the clamp, which prevents them moving sidewise when the clamp 20 is released. The shape of these clamps 24 and 25 when used with a rotary member is made arcual, but it will be seen that if the printing member were flat the clamp would be straight. Outside of the clamps Q4; and 25 are tie pieces parallel therewith and standing in alineinent with the ends of the segment These pieces are secured to the segment at each side of the pocket to strengthen the portion of the segment beneath the pocket to withstand the pressure of the set screws 19.

lVith the printed matter clamped into position in the pocket 10 by means of the screws 19 and the strip 20, the elastic abutments 30 engaging the ends of the spacers 17 hold these spacers in position regardless of whether the type is in position or not. That is, any line or portion thereof or any number of the lines in the pocket may be removed and new matter substituted without removing the clamps 25, it being only necessary to loosen the screws 19 to release the pressure on the lines of type. The screws 26 and 27 pass through elongated holes, as shown at 33 in Fig. 2, allowing a slight sidewise movement, while holding the clamp still in position, thus permitting the removal of the spacers when it is desired to change the size of type.

It will be seen from Fig. 1 that with the type 12 locked in the pocket 10, the matter of this type may be printed at the same time on a sheet to receive the printed matter of the type 14-. The path of the type is indicated in this figure by a dot and dash line 35. The position of a platen is indicated by a similar line at 36. It will be seen. that to use such construction ona iiat printing member, it would only be necessary to provide a pocket having parallel sides and having a bottom parallel with the plane of the t pc.

} It will be seen that such a device as described is very useful in printing matter where it is desired to change a certain portion of it after prmting a given. number of copies; for example, the covers oi catalogues of a firm having several branches where it is desired to change the name of the branch etc. so that the name and address of each branch would be on the copies which they were to receive. Practice has demonstrated that it is convenient to change a portion or all of the printed matter held in a pocket, as described.

Having thus described my invention, what I claim is:

1. The combination of a holding device having a type carrying portion for short grooved type and an adjacent deeper pocket, yielding means for engaging the end of line spacers in said pocket enabling printing lines of slightly shorter length between the spacers to be removed without removing the spacers, and a clamp adapted to press laterally on the printing lines and the spacers.

2. The combination of a type holder for short grooved type having a deep pocket,

yielding means engaging an end of line spacers of said type holder, a clamp carrying said yielding means and having a portion adapted to abut the ends of the type and having projections extending beyond the sides of the pocket whereby it may be secured to the type holder.

3. The combination of a type holder having a pocket adapted to receive type matter, hnc spacers extending beyond the ends of the lines of type, a yielding means engagmg the ends of said line spacers, and a U-shaped clamp carrying said yielding means having one side overhanging the other to abut the ends of the lines of type. 4c. The combination of a type holder having a pocket, means for laterally clamping type matter in said pocket, and a clamp carrying a yielding device engaging the ends of the spacers between the type matter and having an overhanging portion engaging the outer face of the spacers and abutting the ends of the lines of type matter shorter than the spacers.

5. The combination of a holder having a series of parallel rails for holding short type and beside such series a pocket, means for tightly clamping in the pocket line spacers and interposed type lines by side pressure, and means for yicldingly engaging the ends of the line spacers to hold them in place when the type are removed.

6. The combination of a rotary printing member provided with rails for holding short grooved type and having a. pocket adapted to receive taller type and line spacers, yielding means for engaging the end of the line spacers in said pocket, enabling the type matter between the spacers to be removed without removing the spacers, and a clamp for laterally holding the type matter and spacers.

7. The combination of a segment having typeholding rails for short grooved type and a pocket adapted to receive high type matter, line spacers in the pocket extending beyond the ends of the lines of t e, a yielding means engaging the ends 0 said line spacers, and a device secured to the segment for carrying said yielding means and having one side adapted to abut the ends of the lines of type. v

8. The combination of a rotary shaft, 2. segmental typeholder removable thereon and having parallel overhanging rails for holding lines of short grooved type and a pocket for holding lines of taller type, means for laterally clamping type matter and spacers in said pocket, a clamp engaging the ends of the spacers between the type matter, and having an overhanging portion engaging the outer edges of the spacers and abutting the ends of the lines of type.

9. A'segment having parallel overhanging rails for holding short grooved type resting on their shoulders, a pocket adapted to hold taller type standing on their feet with their faces in the same cylindrical surface as the short type, alined with means at the end of the pocket for engaging type and spacers in the pocket, and a clamp for clamping the spacers and interposed type laterally.

10. The combination, with a segment having parallel typeholding rails, of a pocket in the same having a bottom concentric with the rail faces, type taller than the type carried by the rails and standing in said pocket on said curved bottom, spacers between such taller type, a lateral clamp for the spacers and taller type, and a pair of end' bars carried by the segment at the ends of the pocket and forming stops for the ends of the type lines and abutments for the spacers.

i 11. The combination, with a rotary shaft and a rotary frame carried thereby, of a segment adapted to seat on such frame and WVILLIAM R. ALLEN.
