Specification of Letters Patent.

Patented Feb. 5, 1907.

Original application filed April 8,1903, Serial No. 151,691. Divided and this application filed June 22, 1905. Serial No. 266,387

To (til whom it may concern.-

Be it known that I, JAMES W. HOAG, a citizen of the United States, residin at Oakland, in the county of Alameda and btate of California, have invented new and useful Imroveinents in Printing-Presses, of which the ollowing is a specification.

This invention, relating to printing-presses of the reciprocating type-bed and rotary-impressioncylinder type, has for its ob'ect chiefly to so control or operate the type ed or carrier during its reciprocations that tlze type will be brought against and caused to make properprinting cont act with the paper when the type-bed is traveling in one direction; but on the return movement following each impression the type will clear tle cylinder as the bed returns to position for the next impression. By this means the type is prevented from making contact with and soiling the blanket 0r impression-surface of tire cylinder after the printed sheet 1: as been delivered and before a new sheet has been seized by the grippers.

To such end and ob'eet my said improve ment consists, essentially, in the combination with the reciprocating type bed or carrier, of means actuated by or from the carrier itself or by some other moving part of the press to cause the bed or carrier when traveling in one direction to move into th e printing-linc,ivhereby the ty e is brought in contact with the paper, an when traveli'n in the reverse direction to move out of sucl thereb bring the type out of contact with the cy inder-surface, all as hereinafter more fully described, and pointed out in the claims at the end of this specification.

The following description explains at length the nature of the said invention and the manner in wi-ich. I proceed to produce,

apply, and carry out the same, the accoiii-,

panying drawings that form part of this specification ,rcpi'esenrin; what I consider the best manner of applying and carrying out my 1nvciition to attain iho desired object.

Figure 1 is a to view of the press, showing ai is ol' the frame and bed broken-away. l ig. 2 is a. longitudinal section tlrough the center of Fig. 1. Fig. 3 is a sidcelovation. Fig. 4 is a transverse section through tl'e frame of tie press and the traveling bed and 1 Fig 5 is a longitudinal section tvpe-carrii-r. through the bed and the supporting-rails of i printing line, andthe slidable frame, showing the type-carrier in side view. Fig. 6 shows details in side elevation of the type-carrier and the slidable frame and the type-bedin longitudinal section.

The present improvements were originally described with other parts and mechanism forming a com lete printing-press of the re ciproc'ating-be and traveling-cylinder type i in an application made by me in the Patent Oflice under the filing date of April 8, 1903, Serial N 0. 151,691, and the same being separated and divided from the subject-matter covered by my original application are incorporated in and covered by the present application as a division of the said original application.

The drawings represent only such parts and mechanism of a printing-press of the type mentioned as are considered necessary to a clear understanding of the application and operation of my invention.

A indicates the stationary frame, B the traveling type bed or carrier, and C the impression-cylinder.

The bed B receives its movement directly from a crank l) and pitman E. The cylinder is also operatedfrom the same shaft, but in such manner throu h the medium of spurgears F G on the cy inder and racks H l, fixed on the bed and the frame, respectively, that the cylinder is caused to travel with a rolling motion over th e form of type and in a reverse direction to as well as in time with the reciprocations of the bed. Gears of t\\ o different diameters are employed, and one rack is fixed on the frame and the otlrer is carried by the bed. This mode of driving the cylinder from the bed forms no part of this invention, however, and the same is shown and described in connection with the present impro vcinent merely for the purpose of illustrating the type or construction of printing-mac! ine to which my invention is applicable. It will be found adapicd as well i to other printing-machines of tie travelingbed and rotary-cylinder type in which illO cylinder and bed are operated by otl or means, and it is not necessarily confined and r0- stricled by t is description to the particular kind of machine heroin shown.

The trawling bed is provided with an opening in which a i'orni-carrying frame 2 is confined against longitudinal and lateral side-frame in the opposite direction and set movement, but is capable of being moved vertically in and independently of the bod.

to move the slide-frame under the type-car- .a simple and direct manner by a lever 12,

.wosite end of the lever projem ing at one side The GXEBIIL of (iris aiioveuient 1s snl'llcient to bring the type up [0 the piiniin 'line, so that it will make proper contact with the implcssion-surface as often as the cylinder passes over the form in the forward travel, but to 5 lower the form, and thereby throw the type, out of the piindngdine in the return movement oi the cyliz. cczzi'tcr the printed sheet 1 has been delivered and the cylinder is moving 1 in the revcis diiecion to take a new sheet from. the iced ..l:le. i In these periods of forward :noven .entand return throw of the bed the type-carrier is alternately elevated and depressed in time with the revolutions of the cylinder by the following means, the (JGIlSili'IlC'ilOll and operation of which will be understood 1r ore clearly by referring to Figs. 4, 5, and 6: The pelt 2, which I have termed the form-carrier, is a plate supporting a rectangular Frame 3 with in an opening 4 in the bed, in which the franc 3 is movable vertically. Guide-pins 5, fixed in t:c bottom of the bcd,'set looselyin holesin ears 6 7 the front and rear ends of the frame I 3, serve-asguidrs to confine the plate in place 1 and at the same time allow it to rise and drop in the opening. A slidefranie 8, supported by two cross-bars 9 10 underneath the plate 2, is fitted for longitudinal movement in a lane parallel with the face of the type and lias screw-threaded holes for four screws 14, the ends of which bear against tlte bottomv oi the plate 2 at poinis behind and in line will recesses or depressions 16 in the piste, so that while supporting the plate in ho1izc1!.- tal position on the bed the screws act to change that position with reference to the printing-line and raise or lower the plate according as the screws bear on the bottom. of the plate or set into the depressions. These changes in the level of the type-canier are off acted by moving the slide-frame longitudinally beneath the plate 2 at these periods in the movements of the bed and cylinder when the form of type is required to make Contact with the irnpression-surface of the o3 linder or is required to clear the cylinder in the travel of the bed, and they are prod iced from the throw or travel of the bed in loosely pivoted to the under side of the bed st 13 and to one end of which the slideiranie is connected by an arm 17. The op- )f the bed in line with twosi'ops 1Q 20 on the .ran'ze is thrown in one direction by engaging no stop and in the o posits directionas often a 3 it engages the otner stop, with the result If'ing f 'ame backward and set the screws 14 ii to the depressions 16 when the end of the It ver 12 strikes the stop 19, but to shift thethe screws old. of the deptissir 11h Winn. i111.- lcver 1; is brsugh; st Lilfl stop 20. The stops i9 20 we so hii'i. god on opposite sides of the lever that trey act upon it at or near the end oi each ncipiccarion or throw of the bed. They are node adjustable also with respect to the length of tlncnmrcravel of the bed, whereby tire time oi. criiiaci between the end of the lever end the stop can be caused to take place earlier or later in the novenlcnt oi' the bed.

The "ypc-cai-rying frame is provided with leveling-serene 22, working irobeneath tre CdJl ier, lor con vei -icni ly regula ngthe impression oithe 'i ype on the paper.

The reccssrs or depressiors in the bottom of the type-earlier are each i1". clincd on the side nearest the screw, zsseei. in. Figs. 5 and 6, to allow the point of the screw to slide smoothly in and out of the depression. By arresting the slidc-franre at any point in its forward throw before the screws are set entiiely out of the depressions and their points 11st on the inclined facts it will be obvious that the extent of vertical niovenent of the iorin of type can be varied, and its pcsiiion with respect to the printing-line will be afiected accordingly. The extent of the rais ing and lowering movement can thus be regulated by so ad usting the stops 19 20 that they will produce a longer or shorter extent of throw 01 t1: e lever 12.
