DELIVERY MECHANISM FOR PRINTING-PRES$ES.
Specification of Letters Patent.
Patented Jan. 15, 1918..
Original application filed September 21, 1915, Serial No. 51,787. Divided and this application filed February To all whom it may concern:
Be it known that I, HOWARD M. Banana, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Delivery Mechanism for Printing-Presses, of which the following is a specification.
The object of this invention is to provide a delivery mechanism for printing presses which will successfully deliver printed and slip sheets of various sizes, the printed sheets having various arrangements of margins either continuous or staggered, without smutting or smearing the printed matter on said sheets.
The invention includes a delivery cylinder having marginal risers which can be so arranged as to support the printed sheet by its margins only and thus space the freshly printed face of the sheet from the surface of the delivery cylinder.
The invention also includes means arranged to feed in slip sheets to be associated with the printed sheets as they are engaged by the delivery carrier grippers.
A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a detail vertical section taken 'fromfront to rear through a sheet feed rotary printing tion.
Fig. 2 is a detail view similar to Fig. 1 taken in another plane,
Fig. 3 is a detail horizontal through the machine,
Fig. 4 is a plan view of a printed sheet showing certain of its longitudinal margins staggered with respect to the other longitudinal margins,
Fig. 5 is a detail vertical section at the outer end of the endless delivery carrier, and
Fig. 6 is an enlarged detail section through one of the marginal risers showing the rneans for securing the same to the delivery cylinder.
The impression cylinder is denoted by 1 and its plate cylinders by 2. The impression and plate cylinders and the means, such as the cylinder 3, for feeding sheets thereto,
press embodying my invensection may be of any well known and approved Serial No. 78,662.
construction and no specific description thereof will be given.
The sheet delivery mechanism for the press includes a, rotary delivery cylinder 4, mounted on a suitable shaft 5 and provided with a set of grippers 6, which grippers are arranged to take the head'of the printed sheet from the impression cylinder 1, with the printed side of the sheet toward the delivery cylinder and to deliver the sheet. printed side up to the grippers 7 of a cylinder 8 mounted 011 the shaft 9. The slip sheets are fed in from the table 10 by the grippers 11 of the rotary cylinder 12 mounted on the shaft 13, which grippers 11 coactwith the grippers 7 to transfer a slip sheet thereto before the printed sheet is trans ferred to said grippers 7 by the grippers 6 of the delivery cylinder. in the present instance l have shown the cylinder 8 as provided with two sets of grippers 7 An endless delivery carrier 1% is provided at intervals with grippers 15 arranged to take the advance edges of the associated slip and printed sheets and convey the sheets to a point over the delivery table 16. A cam 17 is provided for opening the grippers 15 to receive the associated slip and printed sheets from the grippers 7, and a cam 18 is provided for opening the delivery carrier grippers 15 at the proper time to release the advance edges of the associated printed and slip sheets to permit them to drop on to the delivery table 16.
The sheet illustrated in Fig. 4t is shown as provided with two continuous side margins 19, 20, lengthwise of the travel of the sheet, and also with five intermediate shorter margins 21, 22, 23, 24, 25, lengthwise of the travel of the sheet and arranged in staggered order intermediate the continuous side margins. It frequently occurs in printing that the margins lengthwise of the travel of the sheet are not continuous from the head to the tail of the sheet, and it is to provide means for successfully passing a sheet of this character around the delivery cylinder without smutting the freshly printed sheet that one phase of my invention is directed.
To accomplish this result, the delivery cylinder i is provided with a plurality of marginal risers which are adjustable both latmarginal risers,
circumferentially on the cylinder and which correspond in length and position to the margins on the sheets to be delivered. In the present instance the marginal risers 26, 27, are arranged to engage the continuous side margins 19, 20, of the sheet illustrated, while the marginal risers 28, 29, 30, 31, 32, are arranged to engage the shorter margins 21, 22, 23, 24, 25 respectively of the sheet; the sheet thus being supported lengthwise thereof by its continuous and staggered margins as it passes around the cylinder 4.
The means which I have shown for holding the marginal risers in position around the surface of the cylinder includes clamping plates 36 engaging the risers, slidable shoes 37, spirally arranged undercut grooves 38 in the face of the cylinder and clamping screws 39 engaging the plates and shoes.
This arrangement it will be seen will permit the very rapid positioning of the marginal risers on the cylinder and will also permit the rapid insertion of risers of the desired lengths and in the desired number to correspond with sheets having different arrangements of the margins, whether continuous or staggered.
I provide means for maintaining control of the sheets on the delivery cylinder after the advance edges of the sheets have been released by the grippers 6, said means in the present instance, comprising series of friction rollers 40 carried by spring-actuated rock levers 41 pivoted at 42 to arms 43 adjustable laterally along the cross bar 44 and held in the desired adjustment by the set screws 45. The desired amount of pressure which these rollers 40 exert upon the marginal risers is adjusted by means of springs 46. It is understood that there may be one or more of these rollers 40 for each of the two being shown in the accompanying drawings, and also that these rollers may be prevented from pressing against the face of the cylinder when they ride off the face of the marginal risers. This latter result may be accomplished by suitable adjustable stops 47 carried by the arms 43 and arranged to be engaged by the tail ieces 48 on the rock levers 41. It is intended that these rollers 40 should coact with the marginal risers to maintain control of the printed sheets until the heads of the sheets are engaged by the delivery carrier grippers 15.
The cam mechanism for operating the grippers on the cylinders 4, 8 and 12, may be of any well known or approved form and will not be specifically described herein, it being understood that they are arranged to operate the grippers at the proper times to insure the travel of the sheets through the prescribed paths.
It is intended that the driving connections erally and between the several parts may be arranged to drive the parts at the proper relative speeds, and as such drlving mechanism may be'of'any well known or approved form, no
specific description of the same will be given herein. I
The features of my invention shown and described but not claimed herein, relating to the delivery mechanism without the slip sheeting means, forms the subjectmatter of my application filed September 21, .1915, Serial No. 51787, of which this applicationis a division.
It is also obvious that when-I refer to the elements 4, S and 12, as cylinders, Twish'to include by such term reels or other equivalent means, and that also by the'term grippers, I intend to include any equivalent means.
WVhat I claim is 2- 1.
