Application filed March. 18, 1924. Serial No.699,992. i

To aZZwhom itmay concern." Be it known that I, PERCY; L. SIBOLE, a citizen of the United States, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Im rovements in Suction-Nozzle-Supporting cans for Printing Presses, of which the following is a specification. This invention relates to improvements in paper separating and feeding mechanisms of the type disclosed in the U. S. Patent No. 1,394,181, dated October 18, 1921. p

The said mechanism includes a suction nozzle for separating the top sheet from a pile ofsheets, together with means for operating said nozzle to convey the separated sheet to the platen of the press, which is shown as a Chandler & Price job press.

The suction nozzle is carried by an arm secured to and movable withthe form member of the press and also to the connecting rod which operates the form member.

The object of this invention is to generally improve the supporting means for the suction nozzle, and the means for attaching it to the press, whereby to provide for necesor attaching of the mechanism tothe press,

as well as providing for adjustments which may be required from time to time because of wear or. for other reasons.

With theabove and other objects in view the invention is embodied in a suction nozzle supporting mechanism arranged and con structed as hereinafter set forth and as illus trated in the accompanying drawing in mwhich Figure 1 is a View of my improved nozzle supporting mechanism attached to a press,

with parts omitted and parts broken away. Figure 2 is a plan detail view of certain parts of the said mechanism.

Figure 3 is a view in "elevation of the parts of said mechanismwhich are directly attached to the press.

Only so much ofthe press is illustrated as is necessary to an understanding of this invention. For a detailed disclosure of the press and the paper separating and feeding mechanism, as well asthe construction and by a set screw '17.

operation of the nozzle, reference is made to the U. S. patent aforesaid.

The frame of the press is marked 1 and the oscillating platen isrepresented at 2 and is pivoted in the frame at 3. The form member 4 is the usual Chandler & Price form member which is operated by connecting rods, one of which is'shown at 5 pivoted at 6 to the gear 7 on the press. The gear is shown in outline only so as not to interfere with the other parts of the press which are located behindsaid gear.

Referring to Figure 3, the numeral 8 denotes the form member shaft to which the form member is attached as shown by a portion of the member 4. The member 9 represents the usual swinging ink frame.

The form member shaft carries the usual eccentric stud 10 on which the one end of the connecting rod 5 is journaled.

All of the foregoing parts are standard on this type of press and require no further description.

As set forth in the patent referred tothe paper 11 is supported on an inclined support 12 which rests on a suitable bracket 13.

secured to the press. The top sheet of pa:

per is separated from the pile 11 by a sucsheet to intervening feed tapes or like means as set forth in the said patent.

The rod 15 is secured to a nozzle head 16 The nozzle head also carries a roller 18 which runs on a cam 19 for the purpose of guiding the movement of the nozzle head and 5110131011. nozzle. The nozzle head is further provided wlth an 1ntegral clamping member indicated at 20 by means of which the head is carried by a nozzle arm 21 being secured by a bolt 22.

The nozzle arm, is operated to movewith the press so as to properly move and guide the suction nozzle. To this end there is secured to the press a nozzle arm support to which is pivoted a nozzle arm bracket which carries the nozzle arm.

' Thenozzle arm support is in the form of a casting 23 provided. with two lugs 24,

it in alinement with the connecting rod Adjusting bolts 25, 25 pass through the lugs 24- and engage the connecting rod to firmly clamp the support 23 to said rod 5. The support has also two other lugs 26, 26 which extend in over the rod 5 sideways thereot, see Figure 3. Bolts 97, 27 pass through the lugs 26 and engage the rod 5.

Finally, the support 23 is secured to the term member saatt 8 by a stud 28 which passes through the support and engages in a hole 29 which is normally to'be found in the end of the shaft 8 on the press itself. The support carries a stop 3O.

The upper end of the support carries a bolt 31 by means of which the'nozzle arm bracket 32 is pivoted to the support. The bracket 22 is providedwith lugs 33, 33 adapted to receive the rear end of the nozzle a an 21. A pivot bolt 34 passes through'the lug s33 and the nozzlearm 21 and'adjustin'g screws 35 engage the latter and keep it in proper position with respect tothe bracket 32, which carries a stop 36'.

The parts are so arranged and propertioned that the nozzle head 16 restson the cam 19 by gravity during the operation of the device. As the press opens, the-roller 18 rides up over the cam thereby lifting the suction nozzle with the top sheet upwards away from the pile, and through the further continued movement of the form memher (to the right in l igure l)- the separated sheet is taken away from the pile and at the proper time dropped from the nozzle.

hen the press closes the nozzle head with nozzle is again moved into the position shown in Figure 1.

During the operation of the press, the nozzle arm support remains .lixcd in its relationship to the connecting rod 5, while of course the nozzle arm bracket swings on the bolt 31 as will be understood The invention presents several advantages of particular importance when the device is attached to the press. It is'appreeiatcd by persons skilled in the art that great careis required to properly adjust and position the suction nozzle with respect to the paper, because it the nozzle is not accurately squared and adjusted, the paper cannot be properly placed on the platen or whatever paper teedingmeans may be employed between the nozzle and the platen. The main object of the invention is to provide means for properly positioning the nozzle and'its operating parts.

When the deviceis attached to the press, it will: be seen, that thesupport maybe aecurately adjusted in a vertical plane around the stud 28 and on the form membershat't S by means of the adjusting? and clamping belts or screws 2-5 and 27- which provide four points of adjustmentand:firmly clamps the support to the connecting rod 5.

The nozzle arm is thus adjusted vertically in that its rear end (to the right in Figure 1) is raised or lowered depending upon the adjustment of the support 23 as aforesaid.

Again, the nozzle arm is adjustable laterallyon the pivot boltEd-and finally secured by' the screws 35: The nozzle head is adjustable lengthwise of the nozzle arm 21, said head having a: recess 44) permitting such adjustment, and the nozzle head is likewise adjustable axially on the nozzle arm and is finally clamped firmly by; the means of the bolt 22.

Thusall possible and required adjustability of the device has been provided for to insure quick inst-allat-ion by the simple turning of'a few screws. Thedevice is acessible and may be easily inspected and adjusted from time to-time besides presenting a neat appearance:

VV'hen making ready or tor other reasons, the nozzle head and nozzle arm may be swung upwards out ot'the way as is indicated in dotted lines in'Figure 1', in' which position-the stop '36 abuts and rests against the stop30.-
