This invention relates to paper making essary to stop the operation of the machine in order to prevent the continued feed of the web in rear of the break, from accumulating ive the workman opportunity .to reestab 1sh the proper feed. Such cessation of operation of the machine is of course objectionable in that it causes delay in operation, reduced output, and other objections. On the other hand it the machine is not shut down, the continued feed of the webwill cause the paper to accumulate and pile up in the presses or dry ers or other parts of the machine, according to the point at which the parting of the" web occurs, and this results in serious obj ections and; injury to the parts, and danger and discomfort to the workman. For m stance, the undue accumulation of broke or waste paper ontothe broke troughs of the presses, will cause the-material to fall down on the felts and breakor strain them when the broke is passed by the felt to the next press. And the accumulation of the broke in the dryers necessitates much time in the removal of the waste material, usually accomplished by long spears manipulated by the workmen, frequent injury to the workman standing by, or injury to the dryer canvas or other parts. j

In accordance with the present invention these objections and others incidental to the accidental parting of the web, are avoided by the provision of controllable means for causing the break of the web automatically by the accidental parting of the web, at a point in rear of that where the parting takes place, so although the machine will continue in motion, it will cease to feed the web m a way which will cause the accumulation of the broke in the machine and the objections incident to such accumulation.

The invention also contemplates signaling means brought automaticfllgmto opparts.

eration by the accidental parting of the web,

whereby an indication will be given the workman at once of such parting.

Means andmechanism of diiferent forms and construction may be employed in accordance with my invention in efiecting these objects, and in the accompanying drawings '1 have illustrated one exemplification of such means and mechanism, in which a fluid blast or jet is em loyed, adapted to impinge against the trave ing pa er web at the point in the machine where t e web asses from the couch roll to the first press elt, and o erat-ive to start a break in the web, whic break, due to the tension under which the web is being fed and the condition of the web at this point, will quickly continue laterally entirely across the web and cause the same 'to break clear through, suitable means bein provided cooperative with the traveling we at one or more points in advance of the blast means, and o crating in the'event' of the accidental parting of the web, to automatically bring the blast means into action. It will be understood however that the invention in its broader as sets is not limited to this particular embo. iment, but includes as well, other forms and embodiments which will operate to bring about the desiredresults.

The detailed form and construction of the mechanism and the cooperation of the parts thereof will be fully set forth in thespecification to follow, and'the novel features thereof set out in! the appended claims.

In the accompanying drawings:

Fi 8 is a fragmentary view in elevation showing the relation of the shower pipe to the forming wire to enable the latter to be freed of adhering pulp.

Referring to the drawings:

Referring to Figs. 1 and 2 which show conjointly a Fourdrinier paper making machine, 1 indicates the usual endless forming wire onto the receiving end of which the pulp, from a supply tank or chest 2, is delivered, the said wire in its travel, supplemented by the usual suction boxes (not shown), forming the pulp into a moist selfholding web 3 which passes from the deliver end of th( wire supported by the coucr roll 1, to the conveying felt 4 of the first press 5. The felt 4 carries the Web between the first press rolls 6, and the web issuing therefrom is carried by the felt to the press felt 7 of the second press 8, and after passing between the rolls 9 of the second press, it passes to the third press 10,

and after issuing from between the rolls 10- of this press it passes onto the baby dryer cylinder 11, whence the web passes back and forth around the main drying cylinders 12 and finally leaves the last dr ing cylinder of the series and passes into t 1e calender stack 13. 1

In accordance with my invention, means, in the present instance in the form of a fluid blast deliver nozzle 15, is employed to cause the brea of the traveling aper web when the web parts accidentally in its travel through the machine, which nozzle is arranged to direct the blast against the web at the point where the web is in a moist condition and can be readily disintegrated by the action of the blast. The web is in this condition at the point where it passes from the couch roll 1' to the first press felt,

the blast nozzle bein arranged to point irect the blast, preferably air, against the portion of the web 3 bridging the s ace between the couch roll and the guide r0 1 7 of the first press felt.

The nozzle is supplied with air under ressure from a suits. e source of supply y a pipe 16 which is furnished with a manually operated cut-ofi valve 17, whereby the air blast may be shut off at will as will be presently explained more in detail. Between the valve 17 and blast nozzle, the supply pipe is furnished with a valve 18 for the automatic control of the blast in' accordance with my invention, which valve is normally closed so as to shut off the blast in the normal travel of the paper web through the machine. but which is adapted to be opened automatically in the event of the accidental parting of the web, so as to permit the blast to then act on and cause the web to break and thereby prevent the further feed of the web through the machine at this point.

To effect this object, valve 18 is operated by electrical means in the form of a solenoid core 19 surrounded by asolenoid coil 20 included in a normally open power circuit 21 more fully described hereinafter, which when closed will cause the coil to move the solenoid core endwise, and, through the medium of links 22 connected res ctively with'the core and valve, turn the atter to open position and release the blast.

The closure of'the power circuit is efl'ected automatically when the paper web parts accidentally, by means of contactors in a normally open contactor circuit 23, which contactors are arranged at a number of oints in the machine. contactors 2424 at di erent points in the three presses, a contactor 25 at the baby dryer, and contactors 26-26, etc., in the main dr or section. The contactor circuit when 0 osed, will through the medium of electrically operated means more fully described later on, close the power circuit 21 and will thereby turn on the air blast, and such closure of the contactorcir- 'cuit will take place in the event of the accidental parting of the paper web. To effect this closure of the contactor circuit, the contactors 24 in the presses are of a form which will be held in open position by the tension of the web when the latter is traveling normally through the machine, but which, when the tension of the web is relieved, as when the web parts, will automatically close and will thereby close the contactor circuit. And the contactors 25 and 26 cooperative with the drying cylinders, are of a form which will be held open by the presence of the web on the cylinders in the normal travel of the web, but which whenthe web parts and the leading end of the broken web passes from between the contactors and cylinders, will contact with the cylinder and thereby ground through the machine and close the contactor circuit.

The contactors 24 are each in the form of a lever 27 as best shown in Fi 4 pivoted between its ends as at 28 to a h ired art of the machine frame in such position t at one end of the lever will rest upon and be supported by the paper web where it passes from the delivery end of the felt of one press to the receiving end-of the felt of the next press, the tension of the web in its normal travel through the machine this holding the lever in a position which will hold opposite end out of contact with a contact plate 29. The leveris grounded through the machine frame as at 30 by a conductor 31 and the contact plate 29 is connected in the contactor circuit 23, which latter is grounded through the machine as at 32 as will be presently described .more in detail. As a result of this form and arrangement of the contactors 24, when the paper web accidentally parts at a point in rear of any of the three contactors', the tension of the web being relieved, will allow that end of thelever bearing on the paper, to descend and the opposite end will rise in contact with the contact plate 29, thus closing the contactor circuit and turning on the blast, which impinging upon the paper web at the point between the couch roll and first press felt will cause the web to break at this point.

tactors 24 will thus act to turn on the blast v The conwhenever the accidental parting of the web occurs between the first and second press or between the second/and third press, or between the third press and the baby dryer,

The power circuit 21 before alluded toas o crating the solenoid core 19, may be supp ied by adirect or by an alternating electric current. In the present instance I employ an alternating'current from a power supply line furnished with a transformer 39.. said power circuit normally is open-at the spaced contact points 40 and 41, and starting at point 41, a conductor 42 leads to the solewith a conductor 45 which in turn connects with a conductor 46 leading to the transformer 39", and a conductor 47 connected with the transformer leads to the contact point 40. This power circuit, as before explained, is normally open when the machine is operating under normal conditions with the paper web passing throu 'h the machine intact, but it is adapted to closed when the paper web accidentally parts, as previously described, by an electrlcally operated switch mechanism 48 controlled in its opera tion by a relay 49, which in turn is operated by the contactor circuit 23;

The switch mechanism 48 comprises in the present instance an endwise movable rod 50 car ing four

switch arms

51, 52, 53' and 54 insu ated from said rod. The rod carries a solenoid core 55 surrounded by-a solenoid coil 56, which coil when energized will hold the rod'in the position shown, with the contact switch arm'51 free of the contact oints 40 and 41, with which said arm is a apted to contact to close the power circuit when the coil is deenergized.

The switch arms 52 and 53 are adapted to contact respectively with spaced contact points 57 and 58, and with spaced contact points 59 and 60, at different points in the contactor circuit; and the switch arm 54 is The adapted to contact with contact points 61 'and 61" included-in aswitch operating cirtheir associated contact points and maintaining the contactor circuit and switch circuit closed at these oints, when the core is energized and is olding the power circuit open, but moving to disengage the contact points and opening the c1rc'uits"at these points, when the coil is deenergized to close the powercircuit. v

In the switchcircuit 62- at another point, these are two spaced contact points 63 and.

64, at which point the circuit is controlled by the relay 49, and starting at the point 64 a conductor 65 leads to the conductor 45 which joins conductor 46 connecting with the transformer and returning from the transformer the current passes by conductor 47 to conductor 66, thence to conductor 67 connecting with contact pointw6l, whence the current passes by switch arm 54 to contact point 61, thence by conductor 68 to a normally closed hand-operated switch 69, and leaving the switch the current passes by conductor T0 to the solenoid coil 56, which coil is connected with the contact point 63 by conductor 70.

The relay 49 normally maintains this switch circuit thus traced, closed at the spaced points 63 and 64, and it opens the circuit whenever the relay is operated by the closing of the contactor circuit. To effect this object, the relay carries a switch arm 71 normally contacting with the contactor points 63 and 64 in the switch circuit, and the relay is operated by a solenoid core 72 surrounded by a solenoid coil 73 included in the contactor circuit, the said coil when decnergized, as'in its normal condition, holding the switch arm in contact with the contactor points 63 and 64 and maintaining the switch circuit closed, but when deenergized, causing the switch arm to disengage the contact points and thereby open the switch circuit.

This contactor circuit receives its current from the transformer, and the current flows through the following conductors constituting the circuit. Contactor bus conductor 74 has connected with it the

branch conductors

31 and 38 leading from the several contactors associated with the presses and the dryer cylinders, and said conductor 74 leads to the contact point 59, from which the current passes through switch plate 53 to contact point 60, thence by a conductor 75 to conductor 66, thence through conductor 47 to the transformer, and returning from the transformer by conductor 46, the current passes through conductor 76 connecting with the relay coil 73, and traversing the relay coil the current passes by conductor 77 connected with contact point 58. The current then passes through switch arm 52 to contact point 57 connected to conductor 78 of the contactor circuit which is grounded through the machine frame at 32, as before explained.

in the operation of the parts above described, when the contactor circuit is closed by the closing action of any of the contactors, the relay switch arm 71 will open the switch circuit at the spaced contact points 63 and 64 by disengaging said contact points, and the solenoid coil 56 which had been holding the core 55 up with the switch arms57 out of contact with the contact points 46 and 41 in the power circuit, being deenerglzed, will permit the switch rod 50, and conse- .quently the switch arm 51, to move into contact with said contact points 40 and 41 and thereby close the power circuit.

controlling valve 18v and permit the blast to act in effecting the brake of the web. This same movement of the switch rod 50 in closingthe power circuit, will, through the medium of the switch arms 52 and 53, open the contactor circuit at the points therein where the spaced contact points 57 and 58 and the spaced contact points 59 and 60 are located, and the switch arm 54 will open the switch circuit at the point therein where the spaced contact points 61 and 61 are located. By the opening of the contactor circuit in this manner, the relay coil 73 being deenergized, the relay switch arm 71 will move back to contact with contact points 63 and 64 of the switch circuit and this circuit will be again instantly closed at this point. But it will remain open at the point therein where the contact points 61 and 61 are located, and in order to complete the closure of the switch circuit so as to again open the power circuit and shut off the blast, whose momentary action only will be necessary to start the break in the web, a normally open resetting switch 79 adapted to be manually operated, is employed. This switch is located in a branch circuit 80 of the switch circuit, which circuit 80 branches around the gap in the switch circuit opened by the switch arm 54 as described, and comprises a conductor 81 connected with conductor 67 and connected also with one of the switch points 82 of the resetting switch, the other switch point 83 of the switch being connected with the conductor 68 of the switch circuit. lVhen this resetting switch is closed, the current will flow from the transformer by

conductors

47, 66, 81, switch 7 9, normally closed manually operated switch, 69, conductor 70, coil 56, switch plate 71, conductor 65, conductor 45, and conductor 46 back to the transformer. This will energize the switch coil 56, and the switch rod 50 will be shifted endwise and the switch arms51, 52, 53 and 54 operated to open the power circuit, and close the contactor circuit, and the switch circuit at the contact points 61 and 61".

It will be understood that before restoring the parts to their former normal condition by the operation of the resetting switch as just described, the paper web broken by the blast must be again started through the machine so as to hold the

contactors

24, 25 and 26 in a position which will open the contactor circuit, otherwise and if the resetting switch were operated before the travel of the web was reestablished, the contactor circuit being closed, due to the absence of the web with which the contactors cooperate, the rela would be operated to again open the switch circuit.

The clos. ing of the power circuit will open the blast of: the machine, thereby avoiding any In the action of the blast in causin the break of the web between the couch rol and first press felt, the blast blows the, ruptured web downwardly and because the ,web at this point is weak and unpressed, it can be returned without trouble to the supply tank repreparation of the wet broke to enable 'it to be again supplied to the machine.

When after the cessation of the feed the machine has been cleared out and 'is'ready for the feed. of the paper to .be reestablished,

, the web-is again tendered through the maoperation.

chine, and assoon as it arrives at the calender-st-ack, the resetting switch. 79 is,0p erated to restore the mechanism to its former normal condition in readiness for the next the feed of'the paper-web.-

The only function of the relay 49 is to give a momentary impulse sufiicient only to break the switch circuit. Therefore the ac c'u'mulation of dirt, or other foreign substances on the surface ofthe dryer cylinders,

or on the associated contact-ors, will not interfere with the momentar relay; and a'contact of t e contactor rods for a single instant with the cylinder, followed by interruption 'due to dirt, will be suflicient to bring the switch mechanism 48 into action, which latter will operate with definite power and reliably, to close the power circuit. 'It' is seen therefore that it would not be desirable to operate the mast means directly from the contactor circuit, since, due to the'liabilit of interruption of the circuit from the c ogging of the surfaces 'by dirt, the blast -'wo'uld operate inter- 'mittentlyand inefiiectively with a rapid puffin action.

he relay coil 73 has a high resistance relatively to the switch coil 56 and therefore takes a relatively small amount of our- 1 rent. Under these circumstances therewill be but little, if any, sparking between the contactors and parts of the machine with which-they engage, so that there will be little or no liability of pitting 'the cylinders or p'ther parts 01 the machine with which the cohtactors cooperate,

a; It will be understood that but a momentary operation of the blast will be necessary to start the break of the web at the point where it passes from the couch roll to the first press felt. It is the practice therefore of the'attendant, to turn'ofl' the blast by the cut-off valve 17, just as soon as the break actuation of the is started, and then when the power circuit has been opened again by the resetting switch and the valve 18 thus closed by the deenergizing of the coil 20, the attendant again opens valve 17 so that the blast will be ready ,to' flow 0n the next automatic operation of the'parts.

Or the nearly closed position so as toallow the air to bleed throu h, and accumulate pressure in the pipe tween the valve 17 and the electrically operated valve .18. As thus set, when the valve 18 is turned on, the accumulated pressure in the pipe back of it will cause the air to issue from the nozzle in a sudden pufi or blast which will be suflic'ient to start the break in the web. Under these conditions the valve 18 can be left open,

without material waste of air and until the attendant, after the new web has been started through they machine, opens the power circuit by the resetting switch 79 and thereby causes the closure of the valve 18, it being understood that while this latter valve remains open, the air bleedin by the nearly closed valve 17 will'escape in but very small quantity. On the closure of the valve 18, the air bleedingpast valve 17 will again build up pressure in the pipe back of the valve-.18 ready for another blast or puff through the nozzle when the valve 18 is again opened. I 1

In order to preventthe accumulation of pulp on the forming wire in the continued travel of the wire and the continued feed of the ulp thereto after the web is broken by the last, which accumulation would result in the fall of the pulp from the felt in the lower stretch of the wire at different points and the littering up of the floor, and loss of material, I provide means, brought into ac- 1 tion automatically on the parting of the web, or when the breaking b ast is brought 1nto action, which means will act to shower the lower stretch of the wire and free it of. "the adheringpulp. This means is shown in Fig. 1, and in the present instance consists of a fixed shower pipe 84 extended horizontally transversely above the lower stretch of the wire just behind the couch roll, and suitably su ported from the frame of the ma chine, t e said pipe being formed in its underside with erforations1-84 throu h which jets of a suita le cleansing fluid, sue for instance as white wa'ter, will issue and fall on the travelin wire. The pipe is connected with a suitable source of liquid su ply, and

' is provided with a normally close controlling valve 85 whosestem is operatively connected with a solenoid core 86 surrounded by a COll 87 connected by electric conductors 88 and 89'to the

conductors

42 and 44 of the power circuit 21. The form and arrangement of the parts are such that when the power circuit is open and the coil 87 deencut-off valve 17 may be set to ergized, the valve will be in closed position shutting off the shower, but when the circuit is closed as by the accidental parting of the web or when the switches 69 are operated to turn on the web-breaking blast independently, the coil 87 will be energized and will open the valve and thereby turn on the shower. The shower will act to flow through the wire and clear the same of adhering pulp, and the latter will fall down and be collected in a suitable saveall tanl 9O arranged beneath the Wire at the point where the shower acts, and from the tank the col,- lected material may, by suitable means, he conducted away for use again in the machine In order that the workmen may be instantly notified of the occurrence of the accidental parting of the web, I propose to provide signaling means which will be rought into action automatically when the web parts. In the present instance these signaling means are in the form of electric lights 84 laced in the power circuit as shown in li ig. 1; or electric bells or other forms of si aling means may be employed adapted to h: brought into action automatically when the power circuit is closed by the accidental parting of the web. Or a whistle or siren 91 may be applied to the air blast pipe beyond the valve 18 in order to give audible signal when the blast issues on the opening-of the valve.

The normally closed hand-operated switch 69 in the switch circuit 62 is for the purpose ofopening said circuit and thereby operat ing the web breaking blast independently of the automatic operation of the same by the parting of the web. Such hand-operated switches may be located at different points in the machine so as to be within convenient reach of the workmen at diflerent points of the machine, who by the operation of the switches, may, when occasion arises, stop the further feed of the web by operating the blast means to break the web.

Among the many advantages flowing from the invention as above described may be mentioned the following:

By the immediate detection of the parting of the web and the instant cutting off cit" the feed into the presses, the period of suspended production is greatly shortened. In the event of the artlng oi the web in the presses, the bro e which is discharged onto the broke troughs of the presses, is small and there is no dan er of the accumulated broke breaking t e felts when it ispassed from one press felt to the next press. Also the press felts are saved from sudden strain.

In case of the parting of the web in the dryers the fed sheet cannot build up a large accumulation of broke which would require much time in the removal by the WOlllZ- men who in effecting such removal employ long spears. Under ordinary conditions the removal of the broke by spears causes accidents to workmen standing by and may injure the dryer canvas or other dr *er parts. The removal of the broke in this manner necessitates in most cases the stoppage of operation of the whole dryer section, and the starting up of the section causes always severe strain on the gears and bearings. Therefore it is most desirable to keep this section in motion.

Due to the immediate cessation of the feeding of the material when the web accidentally parts, there is economy in the con sumption of the steam, since the dryers do not have to supply heat energy to unproductive paper. It also saves energy, in curtailing the power which would otherwise have to be employed in heating and pumping the so-called broke, and saves power also on the idle running machine. There is a saving of labor throughout the machine and at the heaters, and obstructions on the machine floor and around the broke heaters is avoided. The dryer canvas is saved. from strain by avoiding the wrapping of the sheet around the cylinders by large lumps of broke passing between the cylinders, rolls and canvas. The worl men are relieved from strenuous watch an they are given more liberty for their other duties, and gear troubles are minimized by preventing the clogging of the same or contact therewith of the paper.

It will be manifest however that these objects may be variously changed and modified without departing from the limits of the invention; and further it will be understood thatthe invention is not limited to any particular form or con struction of the parts except in so far as such limitations are specified in the claims.
