APPARATUS FOR CLEANING FELTS N PAPER-MAKING MACHINES.
" Application filed July 24,
1 This invention relates to devices for the cleaning of felts on papermaking machines,
and 'has for its object the improving 'of the method of'removing therefrom small part ticles of pulp and other forei substances the nonremoval, of which inter eres with the proper functioning ofsuchfelts.
-.To this end weemploy a particular structure and arrangement 0 in the accompanying drawings, but asother mechanical movements may be substituted for those which we now employ without departing from the spirit of our invention, we
do not wish to limit ourselvestoithe par:
: ticular mechanism illustrated, in which:
illustrating the flushing apparatus which we now use.
Fig. 2 is a section across the nozzle through which water is discharged onto; the felt. Fi 3-illustrates thevrelative position of the ushing apparatus and the co-acting suction box.
The same reference characters refer to the same arts throughout the several views.
' Re erring to the drawings, 2-2 represent portions of the side frame of a paper-makmg machine between which the felt 3, travels. Between these side frames and mounted thereon or on an other suitable support) to he paralle with and across the felt,
so as and in proper proximity therewith, we place our flushing a'pparatus- Reference'to Fig. 1 W111 show that the flushing apparatus consists of a nozzle 4, rovided with an inlet nipple 5, adapted to be connected by a flexible tube or pipe (not shown) toa source of supply of water under pressure. The nozzle 4, is mounted von a cross-head 6, slidable on a u1de bar 7. Pivoted in the top of 'crossead 6 1s a forked. thread enga g member 8, adapted to engage with dou is cut, or right and left threads formed on the driving shaft 9. One end of the driving shaftis provided with a driving pulley 10, adapted to be driven from a convenient rotatin part of the paper machine on which the evice is instal ed.
The double cut threads -on the shaft 9, terminate in cam faces adapted to reverse the angle of the forked member 8, to the end that when the cross-head 6 reaches the limit of its normal travel in one direction, the forked member will at once enter the parts as illustrated vided with a longitudinal slot 12, in which Fig. 1 is an elevation, partly in section,
1923. Serial No. 653,597.
oppositely cut thread and so automatically reverse the direction of motion of the crosshead, and the nozzle carried thereby will not .come to rest at the end of its travel for any have employed a cylindricalcover 11, prothe nozzle 4, reciprocates. As the method of mounting'this device is clearly disclosed in Fig. 1, and forms no principal part of our method, a detailed description thereof is omitted. a
Under the felt 3, at a point'directly beneath and in line with the line of travel of the fiushing'device, we mount a suction box 14, in the face of which we form a series of slots. The relative position of the nozzle and box being such that one (or more) slots are positioned on each side of the line of travel of the'nozzle, and one directly beneath it.
The operation of our devices and our method of washing is as follows After the machine on which is the felt'to be washed, has been started, water under pressure is turned on and is ejected from the nozzle 4, with considerable force so that the chisel-like jet of water will loosen and force through the felt anyforeign matter which may have become lodged between the yarns forming the same. As this jet of water will, if continued in one spot for an unusual length of time, cause excessive wear on the felt at that particular place, it is important that the rate of travel of the jet be constant.
.By making the suction box of sulficient 100 width to permit a slot therein to be exposed at each side of the one over which the jet is discharged, we find that the suction on the felt just prior to its receiving the forceful tion is not used. The function of the slot behind the jet is to remove surplus water from the felt in the usual manner.
' The flushing mechanism is preferably so 6 timed that the nozzle travels laterally over the felt a distance equal to the width of the water jet, with each revolution of the felt.
We claim A flushing device for washing foreign matter from the felts on paper making machines, comprising a driving shaft mounted above and across the felt; a nozzle on a guide, adapted to deliver water under pres sure in a chisel-like jet; and means whereby the regular rotation of said driving shaft will cause a reciprocating movement of said nozzle and at a regular speed.
In testimony whereof We have afl'ixed our signatures.
