FLEXIBLE FORM FOR HOLDING AND ASSEMBLING TYPE.

Specification of Letters Patent.

Patented Jan. 14, 1908..

Application filed January 14. 1907. Serial No. 352,165.

To all whom it may concern:

Be it known that I, SUMMERS BROWN, residing at 40 Vihitecross street, London, Eng land, Great Britain, have invented a certain new and useful Improvement in Flexible Forms for Holding and Assembling Type;

and I do herebv declare the following to be a full, clear, an exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and I use the same.

' showing the t My invention consists of a flexible chain form carrying a series of type bars consti' tuting a form for holding type, and enabling the same when set 11 and secured to any orm of rotary printing cylinder or drum, the object'I have in view being .to enable type characters, figures, stops or the like to be set up in suitable rooves between the type bars fitted to the 0 min as hereinafter described upon any suitable and convenient surface, an when filled to wvrap orv otherwise mount and secure the flexible chain form thus constructed upon any kind of rotary printing cylinder or drum. After the desired number of copies have been printed, the flexible chain form may be removed from the drum or drums as the case may be, hung up, or stored away for reuse as often as required, or the type may be distributed.

The Way and manner in which I carry out my invention will be readily understood by reference to the drawing in which Figure 1. shows a single link of the chain carrying the type bars on an enlarged scale. Fig. 2. is a sectional view of two links riveted together. Fig. 3. is a side elevation showing three links, the type bars and type mounted therein as it would appear when laid upon any convenient surface for composing. Fig. 4. is a general plan of chain supported form e when set up. Fig. 5. is a side elevation of part of a drum showing ilexible chain form and type mounted therein.

In the drawings a is an L-shaped link,

the lower part of each link b is recessed or .cut away-sufficiently to enable the next link to he stepped into it and so shaped and pivoted as to render it self-looking, a hole is drilled as at c and the next link' secured to the first by a rivet, pin or the like c the third link being securedto the two first in a similar manner, and so on until a flexible" chain c of any desired length is formed. The upper part of eaclrlink may be slotted to be mounted upon l' dovetail, T, or other shape as at dfor the type bar egrooved as at -.f for the rece tion of the type, or this bar may be attachec to the links by screws, or in any other convenient manner haying the same effect. The type characters g are inserted in the groove f formed by contiguous type bars .e-. The drawing shows in Fig. 4. .two chains c one at each end, but if necesmaybe increased to give such support as is necessary. Fig. 5. is an end: view of a rint-' ing cylinder h showing chain form sibtted type bar as described and the type therein.

It will be understood that when the chain is wrapped round a cylinder such as that shown, the links diverge slightly at the periphery. The flexible form is fastened to the rotary printing cylinder, drum, part of the same or carrier by any suitable means such as a spring -c'- having hooks 'i which engage with holes c in the links at both ends of each chain, and are secured to a in -y' or the like attached to any suita le part of the cylinder or drum, the strength of the spring preventing the form from'shifting its osition.

important feature of my invention consists in the fact that the flexible self-locking form enables the type to be set up therein or thereon in any convenient position, and then permits the form with the type so set up to be safely removed, mounted upon and secured to any kind of rotary printing cylinder,

type cannot escape from type bars in transit.

I may modify the make up of the chain and type form bars or the form of type character or means of fastening in various ways to suit special types of rotary printing the nature of my invention.

It will be seen that since the type is set up in flexible forms independently, the rotary printing machine of whatever type can be (opt constantly employed and that very little interruption or loss of time takes place in the removal of the form, and the mounting up of fresh matter.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a rotary rinting machine, a flexible locking hnks, grooved transverse bars en machines without in any way departing from for-m composed o twochains of pivoted into sary in the case of larger forms, the number drum, part of the same or carrier, so that the gaging with said chains and supported there i 10 fitting said bars, the said links and bars being by and type characters fitting in the grooves 0 said bars and interlocking therewith, the whole constituting'a flexible form adapted to be wound on a type cylinder.

2. In a flexible type form adapted to be fastened on a printing cylinder, apair of chains consisting of overlapping pivotedlinks in combination with transverse type-bars supported by said'chains and type characters adapted to hold said type-characters in place on' a c linder'substantlally as set forth.

' 3. n a flexible type-forrnjfor a cylinder, a

pair of chains each consisting of a series of L shaped links, overlapping and pivoted to each other in their lower parts and recessed on top, in combination with transverse typeholding bars fitting in said recesses, interlooking with the walls thereof and typecharacters fitting on said bars and interlocking therewith substantiallyas set forth.- 1 4. In a flexible type-form for printing my name inthe presence of two subscri ing witnesses.
