Letters Patent No. 111,407, dated January 31, 1871.
IMPROVMENTIN PRINTING-PRESSES.
The Schedule referred to in these Letters Patent and making part of the same.
To all to whom it may concern:
Be itlrnown that I, RICHARD C. WARWICK, of
the city and State of New York, have invented` an Improvement in Cylinder Printing-Presses, (twot'etder5) and the following is declared to be a correct description thereof.
Two-feeder cylinder printing-presses have been made with a press-cylinder above a reciprocating bed carrying the types, and in consequence of the bed having a uniform amount ot' rcciprocatiou from the crank er otherwise, two sheets could not be fed in and properly brought into contact with thetypes,
(when the form Wassmaller than the ordinary size, and a smaller sheet ot' paper reqnired,) because the ced and roller have to he moved a, given distance to bring .the fingers iut-o position for grasping the advancing edge of' the sheet to be printed, hence this class ot' presses is limited tov use with a given size ot' sheet and measurement of form of types, otherwise the paper will not be in proper position for the types, or a margin ot' too great width will beleft upon the paper.
lily invention consists in a secondary or type-bed upouthe main bed, combined with stops, in such a manner that while the main bed receives its regular reciprocating movement so that the gripers-are turned with the cylinder or segment to the proper place to grasp and carry forward the sheets fed from iirst one side and then the other, the type-bed only has the movement necessary to bring the types of the form into the proper' position for the next sheet to he irnpressed.
By this construction the type-bed moves with the main bed in printing the sheet supplied from one side, and when the types reach the position for commencing to print the sheet supplied from the other side of the cylinder, the types and their bed are stopped while i the main bed of the machine, so as to be set to stop the movement oi' the bed l at any desired point, and
the main bed and cylinder or segment complete their movements i'or carrying out the printed sheet and receiving the next sheet to be printed, and upon the opposite reciprocation commencing, thc type-bed and main bed move together, and with the cylinder, and print the sheet, after which the type-bed is arrested as before.
By this improvement any sized sheet of the capacity o f -the press, or less, can he printed, and thc adjustment can he made with rapidity, so that more or less motion can'be allowed to the type-bed.
In the 'drawing- Figure l is a longitudinal section ot' the hed of the press.
Figure 2 is a cross-section of the same.
'lhe frame a of the press carries the driving-shait b and wheel c, which may be rotated by a pinion or by power applied to the shaft b.
The connecting-rod d passes from a crank-pin on c to the shaft of the wheels d', that gear into the racl'cs e below, and f above, upon the under side of the main b'ed 11, and
h is the impression-cylinder or segment. y.
'Ihese parts, except the bed g, are all of the wellknown character made use of in two-feeder cylinder" presses, and the feeding-tables, gripers, or feeding-tim gers are ot' the ordinary character, and do not require further description, and I remark that the cylinder It or segment is geared so as to move as the bed is reciprocated in the usual manner, and delivery-beits and flyers may be employed for conveying away the paper.
The bed g varies from the ordinary'bed used in these presses in the central portion, for, instead of being adapted to receive the form of type and chase, it is lowered to form a platform upon which the secondary or type-bed rests, and is supported upon friction-rollers or slides in such. a manner as to allow of the type-bed l remaining stationary during a greater or lesser portion of the movement ofthe main h ed g.
1t will now be evident that the type-bed l may more with the bd q during the entire rcciprocation of the latter, and that in this ease a sheet of the full size ofthe press can be printed, and a lock to hold the two beds togetherr may be used, or only the friction depended upon to keep the beds in the proper relative positions.
When a shorter or narrower sheet is to be printed the rules or gauges m mare to be adjusted so as to stop the movement of the bed l at the proper poin't of each reci procation.
These rules or gauges m are adjust-ably affixed to I prefer to introduce India-rubber buffers either upon the ends of the gauges m, or upon the bed l where it cornes in contact withsaid gauges, so as to lessen the noise and concussion.
The mode of adjusting the parts so that the edges of the sheets will occupy the proper position relatively ,to the types, and that the types will be arrested by stopping the bed l so that the last edge of the form ot' types will he in proper position to the fingers and edge ot' the sheet when the reciprocation is reversed, will bc fully apparent to any skilled printer, and hence need not be further described.
A. latch or connecting-lock may be applied in any convenient manner to connect the type-bed and main i bed during that portion of the reciprocation in which the printing is performed, said latch being disenin combination with the matin reciprocating bed g of gaged by a. cam or otherwise simultaneously with the the cylinder or segmental two-feeder printing-press, bed l, being stopped by Contact with the gauge or substantially as :md for the purposes set forth. rule m. Dated this 30th day of August, 1870.
RICHARD C. NVARVIOK.
The secondary or type-bed l and stopsv or rules m,
This improvement' is avlilaiblerwhere two cylinders are used with the twq feeders, its well its in sin- XVitnesses:
gle-cylinder or segmental two-feeder presses.
IA claim as my invention- CEAS. H. SMITH,
