PRINTING PRESS.

Application led November 4, 1921. Serial No. 512,852.

T0 all whom 'it may concern.'

Be it known that I, DYER T. KnNDnToK, a

citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Printing Presses, of which the following is a specification.

This invention relates to improvements in printing presses of the type more particularly employed for printing upon cards, booklets or other matter by adding to the matter already thereon the name and in some cases the address of each individual recipient whereby the matter added may be of the same type and present the same general appearance as the rest of the printed matter thereon giving thev impression of an individual 'or exclusive communication; and the object of this invention is to provide such a machine with a type-carrying belt adapted to receive a step-by-step movement to bringl the type carrying links of the belt successively into position to print upon the work. p f

Y A further object of the invention is to provide means whereby that particular set or group of type in the belt, which is in position to print, may be inked after each printing operation.

The invention further consists in the provision of means for arresting the feed of the belt during any desired number of printing operations.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings.

Figure 1 is a side elevation of my improved printing press showing the frame partly broken away tobetter illustrate the operating mechanism, and showing the ink roll carrying guide sectioned on lline 1-1 of Figure 2. y, y v f Fig. 2 isa perspective view showing a portion of the type carrying chain, the links of which comprise receptacles in which the type or printing blocks may be mounted, these receptacles being flexibly connected together. f W

Figure 3 is a perspective view showing one of the receptacle chain links in which a plurality of rows of type or other printing devices are set.

Figure 4 is a top view of the type receptacle link shown in Figure 3, and illus` trating the spring therein for yieldingly binding and locking the type in position.

Figure 5 is a central sectional end elevation through the receptacle shown in Figure 4. It is found in practice very desirable in high grade printed matter such as the printing of invitations, some high class4 cards and booklets and other matter, to be able vto print the name of each individual recipient upon the same using type of the same gen-y eral character as that of the body of the printed matter so 4as to present the appearvance of an4 individual communication. To accomplish this result has heretofore been a very slow and expensive operation but which by my improved type belt printing press may be done very rapidly; and the following is a detailed description of one means by which the desired results' may be accomplished Withreference to the drawings, 20 designates the two side frames lof my improved printing press in which are mounted three belt-carrying rolls 21, 22 and 23. The roll 21 is mounted on shaft 24 and is provided on its face with teeth 25 to engage the spaces 26 between thelinks 27 of the chain '28. On this shaft 24 is fixed a ratchet-toothed driving-wheel 29 which is engaged by the pawl 30 pivotally mounted at 31 on the slide bar 32 and is normally pressed into engagement with its ratchet by means of the 'spring 33. This slide bar is forked at its lower end 34, to straddle shaft 35 and it is provided with a roll 36 which is engaged by a rotating cam 37 on shaft 35 to be raised to act through the pawl 30 to rotate the ratchet wheel 29 and its drive roll 21, the bar being adapted to return by gravity causing the roll-tvo follow the contour of its cam, the drive shaft 35 being driven from a pulley 38 through the pinion 39 and large gear 401 In some cases it is found to be of advantage to be able to make a plurality of successive impressions from a single block or set of type before moving the belt, in which case the pawl 30 is swung back against the slide bar causing the snap 41 to engage the pawl and V retain vit'in inoperative position, until suicient impressions have been obtained from that block of type after which the pawl may be 'released and the step-bystep advancing movement of the chain continued.

In order to position a single block of type, or that set or group lof typecarried bya single link in the chain so that it alone will act upon the work to make its impressions orprint thereon, I have provided an angularly-slraped bed-block 42 the back of which is supported by the front edges of the-frames 2O and its vfront face is provided with a doublev incline, the apex of which' is 4tlattened substantially the width of yone ofthe type receptacle links of the chain whereby when one of these -links with its type rests `upon thisflattened surfacefthelinks oneither side thereof lay against the inclined surfaces and are themselves removed from position to engage the work when presented during the printing operation.

It 'is found in practice of .advantage to ink the-type whilevin position to print upon work,\so that a number of impressions may be taken Vfrom a single set of type if desired, without `advancing the chain carrying the same. 4To do vthis ina simple and effective way I have ymounted a set of ink rolls in an ink-'roll carrying slide -bar 47 vthe upper rolll of the set being mountedon links'pi-Voted in the carrier-bar, the samebeing pressedinvwardly bylthe springsl to cause this uppermost roll-to follow over-or across the-top-of the type mounted in the block which is seated in its operating or printing position. This carrier bar is mounted in these edge guides 52, and is actuated bythe cam '53, vsee Figure 1,'on the shaft 35, through the connections 54, 55 and '56, whereby when `the cam is rotated on the shaft 35 it operates through the connections above described to `move the slide bar upwardly and cause the rolls to first pass over the ink disk 57 and thenup overthetype about toiperform the printing operation.

In order to rotate this inking disk 57 upon each-operation of the press I have providediaipawl 58 pivotedat 59-to the arm 60, which Varm is provided with a latch'l vat its inner end, and a block 62 is positioned on the :roll-carrying slide bar 47, kso that lwhen the bar is raised this block passes ythe latch 61 without operating the inking disk but as the bar returns this block 62 engages :the latchl and rocks Ithe lever on its lpivot 63 to raise the ypawl 5.8 to engage 4and `rotate the ink disk 47. Y

The work may be carried by any suit-able means but I have herein shown al platen 64 on the inner face of which it may be dech-ain.

vforwardly towards the type, I have provided a tipping arm 7l pivoted at its upper end at 72 to a -lu-g 7 3 on the platen and at its lower end' at 74 to the frame whereby the forward 'swinging `movement of the platen causeslit 'to present its work squarely -to the type.

My improved chain is especially constructed for my particularpurpose,lthe same comprising a multiplicity of links providing a type receptacle formed `in rectangular or trough shape, its height bein-g a-li-ttlei less th-an that ofthe usualy or ordinary typeland its widthbeing sufficient toreceive any desirednumber of lines of .type which maybe set therein with `the usual spacers v76 and all locked by Vmeans of springs 77 and held firmly during la printing operation, or in some cases instead of the ordinary type, lines of type may be mounted in `these receptacles, electrotypes Cor cuts of any description may be removably mounted and locked therein. to perform lthe lprinting operation.

In order to more securely lock or retain the spring -77fand the type mounted in 4the receptacle I have bent inwardly as at 78 the upper edges of the receptacle in which the type are set so that when-the spring is once forced-down beyond the inset edges it is -etfectually prevented from `becoming loosened, or drawn out by the ljar or action of the press, yet by "this construction the type in these receptacles may be readily removed and replaced by a fresh set as often as desired.

These receptacles may be connected together by ordinary chain links 79 or by any other `suitable means to form a continuous I preferably form these chains-in duplicate and provideeach'withmeans whereby it may be readily taken Aapart after it has performed `its work; and .replaced by another chain havingl a fre-sh setoftypetherein so -that-theoperation ofthemachine may Abe continued duringthefsetting .ofany type in the links of the removed chain thereby Alosing only that time required to change ients thereof, or it may be employed for any other similar Work for which it is adapted.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being deiined and limited only by the terms of the appended claims.

I claim:

l. A printing press type belt comprising a plurality of Vtrough shaped type rece-ptacles linked together in spaced apart relation, each receptacle being adapted to receive a plurality of lines of type and spacers, a spring carried by each receptacle for binding the type therein, and means carried by the receptacle for retaining the spring in operative position.

2. A type receptacle Jfor a type belt, comprising a trough like structure for the reception therein of a plurality of lines of type and spacers, a leaf spring adapted to lie between the Wall of the trough like structure and the type and spacers, and ine-ans carried by the trough like structure for retaining the spring in operative position.

3. A printing press type belt comprising a plurality of trough shaped type receptacles linked together in spaced apart relation, each receptacle being adapted to receive a plurality of lines of type and spacers, a spring carried by each receptacle for securing the type therein and means carried by the Wall of the receptacle and overlying the top of the spring.

4. A printing press type belt comprising a plurality of trough shaped type receptacles linked together in spaced apart relation, each receptacle being adapted to receive a plurality of lines of type and spacers, a spring carried by each receptacle for securing the type therein and an in- Wardly extending member carried by the Wall of the receptacles for retaining the spr-ing in operative position.

In testimony whereof I aiX my signature.
