SHEET-DELIVERY MECHANISM.
Application filed July 12, 1919, Serial No. 310,515. Renewed January 18, 1923.
To all whom it may concern; 7
Be it known that I, J OSEPH Wnrrn, a citizen of the United States, residing-atlis- .cataway Township, State of New Jersey (postoiiice address, Bound Brook, New J ersey), have invented certainnew and useful Improvements in. Sheet-Delivery Mechanisms, of which the following is a specification. 1 j
This invention relates to sheet delivery mechanisms forprinting presses or the like. One of the objects-of my invention is to provide means by which sheets, when delivered to the ordinary sheet support such as a board or trays, may be held more or less suspended while they are being positioned on the support or pile of paper. With this and other objects in View, my invention consists of certain novel features of construction, combination and arrangementof parts as will be more fully described and pointed out in the appended claims.
In the drawings, Figure 1 is aside elevation of a portion of a delivery mechanism of a form.which I have adopted for .purposes of illustration and to which my novel apparatus is shown applied; Fig. 2 is a plan view of Figure 1.
For purposes of illustration I have chosen the type of delivery shown in my prior Patent No. 1,211,512, granted January 9, 1917, portions of this delivery mechanism being shown more or less diagrammatically since the details thereof are fully illustrated in my said prior patent.
In the drawings 10 is a sheet carrier of any form having grippers 11. Cooperating with thecarrier 10 is a sheet delivery mechanism which in the form illustrated com.- prises a pair of chains 12, 13 running on sprocketsll, 15 mounted on shafts 16, 17. The shafts 16 and 17 are driven at constant speed and the chains 12, 13 are provided with one or more gripper shafts 18 carrying sheet grippers 19. Beneath the lower part of the path of travel of the grippers 19 is a sheet support or delivery board 20 which preferably is provided with sheet joggers comprising in the form illustrated a front jogger board 21, side jogger boards 22, 22 and a rear jogger board 23.
A sheet from the carrier 10 passes to a set of the grippers 19 on the carrier chains and from thence is carried horizontally over the board :20 until the head of the sheet is approximately in theposition shown in Figure 2 at which point the grippers are open and the sheet is permitted to drop on the board 20 oron the top of the pile of paper which may have accumulated onthat board. The jogger boards are moved toward and away from the pile in the usual manner to gently push the sheet into its proper position 011 the support. j
r The construction so far described is well liIlOWll and is substantially that illustrated in my said prior Patent No. 1,211,512, which patent shows a set of grippers to carry a sheet horizontally over a delivery board and joggers which operate to jog the sheet as it is dropped into position.
I have found that as the sheet being delivered drops'on the top of the pile it is liable to engage the pile at various points so that the jogging is made diflicult because of the adhesion between the sheet to be jogged and the top sheet of the pile. Since the joggers depend merely on a light push on the edges of a sheet it will be obvious that any resistance to such a push will result merely in folding up the edge of the sheet without properly jogging it.
In order to overcome this difficulty vide a means by which a current of be delivered beneath the sheet ped, so that the sheet will float into position and be jogged at a time when a layer of air is between the sheet and the top of the pile. As one form of such means I have illustrated means for blowing a plurality of currents of air horizontally beneath the sheet as it is dropped to the pile, these air currents being delivered in a direction substantially opposite to that in which the sheet is being carried by the sheet carrier. These air currents are delivered through a pair of pipes preferably located as shown at the left of Figures 1 and 2.
These currents of air may be continuous but preferably I allow the air to blow only for a. short period before the head of the sheet is released by the grippers 19 and cut it off shortly after the time the sheet begins to drop.
It will be seen that as the sheet is carried out horizontally over the board 20 the air from the pipes 25 passes beneath the sheet and tends to keep it separated from the top- I proalr can as it 18 dropmechanism it will he iindeistbotl that it may be applied be man different toms; While preferabl use jogels in connection with "Inov'el arr'ah eihent it Will also be understood that 'sueh jogger-s are not essential,- it being Beneficial to suppl the air bur-rents beneath the -sheet when it is desired to drop u'eh sheets i-fito defihitfe mu fixed opening eetwemsneet guides found on same types of delivery board. 1 I
'Itivill in's'oibe iiiiderstood that While I preto' delivefthe air currents in the cl'ife'c;
tions illustrated in Figures 1 and 2, other directions maybe utilized solong as the presence of air beneath the sheet as it is being dropped, is insured. V
