AUTOMATIC oonrrnoLLINe DEVICE. FOR PRINTIIiG I MACHINES.
Application flied August 15 1925. Serial No. 50,505.
My said invention relates to automatic controlling devices for printing machines and it is an object thereof to provide interdependent controlling means for air and gas supplies such as are used in printing presses of certain types.
The general character of the machine to which my present improvements are or may be applied is disclosed in my Patent No. 1,429,301, September 19, 1922. As is well known to those skilled in the art difficulty arises in the handling of newly printed sheets in the press such difficulty being due in large part to the static electricity with which the machines become charged. To
, overcome this it is customary to heat the sheets by means of a gas flame as they leave the periphery of the impression roller and are discharged on the guidefingers from which'they are taken by rocking fly sticks and deposited 'in a pile on the receiving table of the press. I q 1 Another difficulty that is commonly experienced consists in the tendency of the corners and edges of the newly deposited sheets to curl up as thefly sticks recede, whereupon they are liable to be creased at the corners by the sheet next following. Air pipes are provided-by means of which jets of air are projected on the parts of the sheets thus liable to be rolled up,.such jets holding these parts of the sheets down and preventing them from being bent down and creased by the sheets subsequently added to the pile. It is also customary to I force the jets of air in between the descending sheet and the remainder of the pile both to retard its descent and for drying the ink thereon to prevent smudging of the sheets.
In the practice of my invention I have provided'interconnected means for supplying air and gas for the purposes indicated together with a common automatic control for such means.
Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts Figure 1 is an elevation of the mechanism above referred to, i p
Figure 2, a longitudinal section of the automatic controlling devices,
Figure 3, a transverse section on line IIIIII of Figure 2, i
Figure 4, a transverse section on line IV- V of Figure 2, and
Figure 5, a horizontal section on line V-V of Figure 2. w. 7
In the drawings, reference character. 1 indicates an air inlet pipe communicating in turn with the cut-out 2, a pipe .3, flexible tubing 4 and pipes 55, thelatter leading into ,an automatic controlling device 1 at 6' and the air passing through a body member 20 to emerge at ,7 where it enters a distributing pipe '8. Said-air distributing pipe has perforations 9; arranged in anyconventional or desirablema'nner. along one or more sides thereof. A gas'pipe 10 enters the automatic control at .lliflnd'wtll gas passes through a; body member 21 forming the lower part of said control and out by way of a port 12 which communicates withv bers are pipe sections-of somewhat irregular form to'permit them to be joined together as hereinafter described.
A pipe 15 projects from one side of the automatic control and is provided adjacent its outer end with an aperture -16 for a pilotflame. The cut-out 2 is closed by .a lever 17 when the press is stopped as by a cylinder trip orother device and at this time the compressed air in the automatic control and parts leading thereto is exhausted into the atmosphere by means of pipe 18.; A spring 19 closes the cut-out when the pressure on lever 17 is relieved.
; The'automatic control comprises two body members 20 and'21 which are provided with a common wall 29 here shown as forming a part of the section '21. They are alsoprovided with flanges 22 and 23' having flat meetingfaces topermit an air-tight engagement, said flanges being heldtogether by A spring 35 extends downwardxfrom the head of the .valve'and rests at its lower end in a. seat formed by a hollow screw 45; The
screwv 45 has engagement with a hollow screw 44 which is internally threaded throughout its length- A lock-nut 46 is threaded on the screw 44 and a locking screw 47 has threaded'engagement' with an opening in theheadsof. screw 45. .The locking, screw 47 is provided with a lock-nut 48. It will be seen that the locking means. locks the two hollow screws in place and that a considerable range; of adjustment is provided for the spring 35 so as to vary its action on the valve.
The stem 34 of the valve projects up throughlan' aperture in the partition 29 between the two body members, said partition in this instance!being-formed integral with the lower-bodymember.- A valve member 36 pivoted-at 87 on lugs 38 hasa bend or bight resting on the upper end of said valve stem. It will be seen that the valve 36 projects intothepath of theai-r currentthrough the body member 20. So long as there is a. considerable-air current passing. the valve 36 it will force. the valve downward so as to open the portthrough the partition 27 and permit gas to flow to the pipe 13,. butwhen theair current fails the spring can, lift thevalve 30 and close the port, forcing the valve '86 towardupright position. It will be evident that the air current will cease when the lever 17 is operated against the tension of thespring 19 and that thereupon the flow of gas will also. cease. Thehpilot light, however, continues to burn, asv it is supplied through a port 49 inthe lowerbody member-which: port leads-tothe aperture at 16 froma point back of the partition. 27.
A passage is-also provided at 40 through the-partition-i29 by means of which. air is supplied'tothecurrent of gas and thispassagemay-be regulated by means. of a screw 41 having-atapered end portionso as to pro:
vide the correct amount of air .for commingling=withthe'gas to producethe most efficient combustion. Alock-nut 42 is mounted on the screw- 41 for securingiit in place.
Itwill be obvious. to those. skilled in the I art that various changes may be madein my devicewithout departing from the :spirit of the invention and therefore I do not;limit myself to what is shown in the drawings and I described in the specification, butonly as indicatedin the appended claims. It will. also be obvious.-that:the device maybe used for otheranalogouspurposesand in other machines than printingpresses, as a device of this character. maybe useful wherever the airunder pressure, a gaspipe having a plurality of outlets adjacent the path of the sheets of paper, means for stopping the flow of air to the 2LlT emission pipe, and means controlled by the flow. of air for stopping and startingthe flow of gas in the gas pipe, substantially, as set forth.

In a printing press having feeding means for sheets of paper and pneumatic controlling means for such sheets, a pipe having a plurality of outlets for emission of air under pressure, agas pipe having a pluralityof outlets adjacent the path of the sheets of paper, means for stopping the fiow of airt the air emission pipe, means con trolled by the flow of air for stopping and starting the flow of gas-in the gas pipe said means comprising a valve in the gas pipe, a valve in the {air pipe, and resilient means tending to close the'valve, substantiallyas set forth.
In a, printing press having feeding means forsheets of paper and pneumatic controlling means for such sheets, a. pipe having a plurality of outlets for emission of air under pres'sure,fa gaspipehavinga plurality of outlets adjacent the path .of
the sheets of paper, means for stopping the flow.- of airto the air emisslon pipe, means controlled by the flow of air for stopping and starting the flow of gas inthe gas pipe, a pilot light adjacent said gas pipe and a passage to said pilot light from a point an terior to said valve, forth. 1 v v 4.

5. In a printing press havingfeeding means for sheets of paper and pneumatic controllingv means for such sheets, parallel air and gas pipes having spaced outletsat intervals in their length parallel pipe sec-.v
tions connectedpto said pipes,{a partition in one of said. sections said partition having a port, a valve for the port, a pivoted valve in the other pipe section operable by the current in said pipe to opensaidfirst-named valve, and constantly-acting means tending to close said valve, substantially as set forth.
