PRINTING-MACHINE.

To ('77 whom/it may'concem:

it known that LLEwIs E. Monsieoiw, a citizen of the United States, aiid resident of Newark, in the county of Emex and State of New Jersey, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification.

This invention relates to improvements'in' printing mechanisms and the object of the invention is to provide generally "improved devices or mechanisms for job presses with particular reference to the separating and feeding operations thereofl' Aside from the general aim of the invention which is to provide improved means for carrying out the several said operations struct the various parts and combinations thereof in a simple, practical manner with a View of being able to transform a handfed and hand-delivery job press into an au tomatic machine at a relatively low cost.

.Other objects of the inventionwill appear hereinafter.

Accordingly, my invention is embodied in mechanisms, parts and combinations there of, arranged and combined as hereinafter set forth and as illustrated in the accompany-- ing drawings in which Figure his a side elevation in outline of a job printing press equipped with automatic mechanisms, according to my invention;

Fig. :2 is a perspective view of the separating, feeding a l. delivery means.

The lEM-"LHtlOIl is illustrated in'conuection with a well known type of job press, but I claim the use of the invention on other types of printing presses as Well and where only the mechanical ability of'one skilled Bpeclfimtzlnn rimers iatent. Application and November 2, i915. Serial m. 59,161.

By these means the-paper stops are periodically lifted to permit the paper to out from under them. -The paper, which includes carboard, en-I velops and all other stock adapted to-be printed on a job press, is combed outas shown and placed vbetween the guides 12' with the upper sheet projectingbe 0nd the sheet underneath and having its frontedge squared against the'paperstopsi" f The paper is fed to the platen by means of a paper separating and feeding device which comprises the suction cup 24 adjust, ably carried by the hollow rodor tube 25 by means of a set screw The rod-25 is I secured'in the free end of the feeder arm 27',

- which is pivoted at 28 to the lever 29. Suitk able stops 127 and 129 are provided to prevent the arm 27 from falling down and to permit it to be moved upward into a position of rest in order to make the press ready.

The arm 29 is pivotedat 3,0 011 an augiliary in the cam 33. '34.- denotes the pump whici is connected by a flexible tube 35 to the tube aforesaid and the suction cup 24. The

latter has a'hollow stem and a recessed foot 36 provided with a lining. 37 of leather,

frame 31 and carries a cam roll 32riinnin Hit rimmed wheel on the tube 25 and which forms a supporting and guiding means for the said tube and the suction cup 24 in that the said wheel runs on cams 39 and 40. Cam 39 is fixed to the feed board and cam 40 is securedto. the platen 2. The pump is operated from the shaft 41 in the auxiliary frame 31, which may be secured to the press or to the floor in any suitable manner. The shaft 41 has a crank 42 which is adjustably connected at 43 to the piston rod 44 of the pump. The shaft 41 carries a ear 45 in mesh with the gear 6 aforesaid.

he top sheet of paper is separated from the pile by having its front edge sucked up by the suction cup 24 during the suction stroke of the pump, the commencement of which is shown in Fig. 1, where the separator is about to pick up the top sheet as soon as the cam roll 32 gets on the low part of cam 33.

At this time the paper stops 16 are raised because their operating roll '23 is onthe low part of the platen locking cam 18. As the press now opens, the cam 33 causes the lever 29 to move forward or to the left in Fig. 1 with the separator and the latter moves down upon the platen with the sheet and delivers it directly upon the platen. Durin its forward motion the separator is guide by its wheel 38 running on the fixed cam 39 and as the platen reaches full open position, the wheel 38 passes from the cam 39 onto the cam 40 on the platen as shown on Fig. '2. The separator has a fixed length of movement from the rear of the feed board to the rear of the platen, but the sheet may be released by the separator to deliver the sheet upon the laten in any predetermined position. To this end the pump casing is provided with a pin 134 and the piston 135 is provided with an aperture 136. A cover 137 is pivoted on the piston and is normally closed upon the aperture 136 by a spring 138 secured in any suitable manner. The cover has a tail 139. When the latter strikes the pin 134 on the suction stroke, the tail is depressed and the cover lifted to admit air through the aperture 136 to the connection 35 and the separator. By raising or lower ing the pin 134, which is held frictionally in the pum casing, the point of release of the sheet justed. On the return. stroke, the separator is first lifted as the cam 40 moves down with the platen and from this cam the wheel 38 passes back to the fixed 'cam- 39 and to the aper.

en the top sheet has left the pile the paper steps 16 move down again as now the roll 23 will run on the high part of the' platen locking cam. During the movement of the sheet from the feed board tocithe m the separator may be adciple there the rod'25 as is apparent from Fig. 2. 49 is a paper holding device comprising a leaf 50 a justable lengthwise at 51 and pivoted at 52 to a support 53. 54 is a spring which forces the leaf down on the rear edge of the paper, so that as the top sheet is pulled off the leaf 50 serves to retain the sheet next to the top one and prevent two sheets from being picked up at one time. The object of the paper holding device 49 is to permit the operator to leave the press momentarily to get more paper for instance. Normally the operator is supposed to keep his hands on the paper and see to it that only one sheet at a time is fed to theplaten. 7.

After the paper has been printed it is removed from the platen by the delivery me'chto the brackets 10 at 59 and the gui es may be moved along said bar for adjustment according to the width of the sheet. 60' is a supporting finger secured to the bar-58 and which rests by the weight of the feed table on a cam 61 secured to the platen as is clearly shown. In Fig. 1 the paper feed table is lifted by said cam 61 and as the platen moves up the feed table is lowered to the position shown in Fi 2' to guide the paper onto the platen. e feed table is "adapted to be swung upward on its pivots 59 in order to make the press ready.

The operation of the devices contained in this invention will be clear from the foregoing. It is also clear that hardly any change is made in the press itself but that the entire feeding and delivery apparatus may be built as an attachment to the press and that by properly mounting the .other auxiliary parts, a hand operate press may be quickly transformed in an almost wholly automatic machine. A

The several parts and details may be va ried in their construction from the ecific forms shown and described, and I claim all such changes and modifications in my invention as properl come within the princlaims.
