SLUECING DEVICE.

Application led July 12,

To all tf1/tom it may concern:

Be it known that l, Bonner d. lilo-Geni.- LAND, a citizen oi the United States, and resident of llniiurst., Long island, in the ity of Queens, city and State oi New Yorlr, have invented certain new and us improvements in Sluicing llevices, of which the tollowing is a specification. f

rlhis invention relates to a sluicing du vice for filter presses and has for its primary object to provide a simple and effective vinsane for removing the coagulurn or calrc formation which collects upon the ilter cloths of filter presses such for instance as are used in the proce/estoie reiining sugar.

fis is well known in the art, in the refineinent of sugar, the collected inaterial adhering to the exterior surface oi the lilterV cloth is removed hy ineens of wash water discharged from a A extending' into the fili; 2r casing This pipe is longitudinally niovahlo and is likewise oscillated in order that the discharged water will strike the ilter cloth over its entire area. t

lt is the primary object and purpose of present improvement to provide a device of this nature wherein means is employed lor automatically reversing the reciprocation of the wash water pipe at the end or its stroke in each direction so as to ohviate the necessity oi employing an attendant to manually operate the water pipe.

W ith the alcove and other objects in viewa the invention consists in the improved automatic sluicing device and in the form, proportion and relativel arrangement of its several parts to loe hereinafter'rnore iully described, illustrated in the accompanying drawings and subsequently incorporated in the suhjoined-clairns.

ln the drawings wherein l have disclosed one simple and practical embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a side elevation partly in section showing a preferred 'torni oit the invention;

l*1 igure 2 is a section taken on the line 22 of Figure 1, and

-Figure 3 is a fragmentary elevation showing the manner of reversing the ratchet engaging pawl.

Referring in detail to the drawings, 5 des- 1921. Serial No. 4347177.

ignates the longitudinally reciprocating and oscillating wash water pipe which extends into the il''er press, a portion of which is indicated at 6. The pipe 5 is connected to a fixed pipe section 7 through 'the inediuin of a sleeve 8 which is provided with suitable packing to prevent the escape of the water, while permitting of the relative movement oit the pipe 5. y

Upon the pipe 5 an eirteriorly threaded sleeve 9 is securely iixed by one or more set screws 10. A nut 11 has threaded engagement upon the sleeve 91, said nut being integrally connected at one oi" its ends hy means of the radial arms 12 to a wheel 13 the outer peripheral face of which is provided witli a continuous annular groove le. Upon the opposite end of the nut 11 an annular flange 15 vis iornied and to t e end tace ci said nut a colla-r1.6 is rigidly fixed and has a flange 1'? spaced fronithe flange 15. The space between these flanges receives a ring or annulus 18 which is coni nected by a plurality of bolts 19 to a lined part ol the iilter press. The ring 18 thus holds the nut 11 against a longitudinal moveinent with relation to the sleeve 9 while perinittin@ ci.3 its rotation upon said sleeve.

To the arms l2 of the wheel 13.3 ratchet wheel 20 is securely bolted or otherwise rigidly Vfixed, The teeth 21 ot this wheel are of less width than the width oi the wheel and terminate in spaced relation to its opposite side edges.` Y

Upon the pipe 5 an arin 22 is securely .tlxed by means oit the clamp 23 or equivalentdevice and in one end of this arin the pin 24 is mounted. A pawl 25 is loosely engaged upon the end ci the pin 24' and to each side of said pawl and at opposite sides of the axis of the pin 24: a pair of spaced lugs 26 are fixed. W ith the respective pairs ci. lugs, radially projecting tinge-rs 27 secured upon the peripheral face of the wheel 20 at relatively opposite sides of the teeth 21 are adapted to coact in a manner to loe later explained.

The clamp' 23 for the crank arm 22 is provided with a radially extending lever 28 upon which the collar 29 is fixed. A `connecting rod 30 operated by a power driven crank (not shown) is ilexibly connected to the collar 29 by means of a link` 3l, a, sinn ilar linlr connecting the other end or' said rod to the oWer crank. These links transmit an oscillating movement to the water pipe 5 in the reciproeation of the rod 30 and also permit of the longitudinal movement of said pipe.V 'The collar 29 may be readily adjusted on the lever 28 so as to regulate the oscillation of the pipe.

lt Will be noted that the paivl 25 is provided at its free end and at the opposite side edges thereof with lugs 32. @ne of these lugs is adapted to coact .vith the ratchet teeth 2l when the paivl is disposed at one side of the crank arm as shown in full lines in Figure 2, While the other of said lugs coacts with the ratchet teeth When the paivl is reversed and disposed on the opposite side of the crank arm as illustrated in dotted lines.

A friction brake band 33 is engaged upon the base Wall of the groove in the .vheel lf3, the ends of said band being connected in spaced relation toV each other to a grooved YWheel 34 mounted to rotate in the supporting standard 35.' A horizontally entend e' lever 36 is fined at one of its ends to the axis of said Wheel and upon the other end or Vsaid lever the Weight 37 .is pivoted.

In the operation of the device, when the pavvl 25 is in the position shovvn in full lines in Figure 2, upon the doivn stroke of the rod 3G the ratchet 2O and consequently, the nut l1 and the `tvheel 13 together withV the pipe 5 and the sleeve 9 are given a partial rotation, the frictional resistance of the brake band 33 being overcome and all of said parts moving as a unit. ln the upstrolre of theV rod 30 the rotation of the iipe 5 is reversed and the pawl 25 moves idly over the ratchet teeth 2l. ln such reverse movement, the ratchet 20, the nut ll and the Wheel 13 are held stationary by the brake band 33. Vrlhe sleeve 9 being fixed upon Ythe pipe 5 rotates with said pipe and with respect to the nut ll with which said sleeve has threaded engagement. The pipe and the sleeve are thus caused to move longitudinally in one direction through the nut, the extent of such movement depending upon the pitch of the threads and the operating stroke of the rod 30.V ln this longitudinal movement of .the pipe, the crank arm 22 moves therewith and accordingly, the pavvl 25 is shifted longitudinally lith respect to the ratchet. ln the succeeding doWnstrolre of the rod 30, the rotation of the pipe 5 is again reversed and all of the parts move as a unit. It is thus seen that longitudinal movement is imparted to the Wash Water pipe .5 only upon the upstrole of the rod 30. After one complete rotation of the ratchet 20 has been made, one pair of the lugs 2G at one side of the paivl 25 are disposed in alignment with the linger 27 at one side of the ratchet wheel so that upon the initial movement of the paw] 25 in a reverse .direction on the succeeding upstrolre of the rod 30 one of the lugs 25 will engage the finger 27 as seen Figure 3 of the drawings so as to lriclrvor throw the pavvl to the opposite side of the supporting pin as shoivn in dotted lines in Figure 2 whereby the ratchet will be positively rotated together with the pipe 5 and sleeve 9 in the continued upward movement of the rod. rllhe independent os cillation of the vater pipe 5 and sleeve 9 Will now taire place upon the down-stroke of the rod 30 so that the longitudinal movement of said pipe will be reversed. After a series of s .cli operations, the longitudinal movement of the pipe 5 is again reversed by the engagement of thev lugs 2G at the opposite side of the paul 25 with the finger 27 located at the other ide of the ratchet 20. ln this manner it Will be seen that a combined oscillatory and longitudinal move- 1 ment is imparted to the Wash Water pipe and at the end of the longitudinal movement in each direction,such movement of the pipe is automatically reversed. Therefore, in the use of the device in connection with filter presses, no attention Whatever upon the part of the operator is required. Any desired number of oscillations of the pipe Vmay he obtained in the longitudinal stroke of the pipe in each direction by simply varying the spacing of the teeth on the ratchet ivheel 2O and the extent of movement of the pavvl 25 in each stroke of the connecting rod 30.

l have shown the extreme positions of this paivl when activelyV engaged with the ratchet teeth in dotted lines in Figure 2, and three such movements of the paivl are equivalent to one complete rotation of the ratchet. is not of essential importance and the extent of each of the oscillatory movements might be decreased or increased with a corresponding variation Vin theV length of the intermittent longitudinal movements of the Wash water pipe, Without aecting the principle of operation.v By reason ofthe combined oscillatory and longitudinal movement of the Wash Water pipe, the cake formationvon the surface of the filter cloth Will be loosened over the entire area of the filter surface and dislodged therefrom.

ln the foregoing description and the accompanying drawings, l have illustrated one embodiment of Vthe device which l have found to be very satisfactory in practical operation, but it will be understood that the invention might also be produced inve-.rione otherV alternative 'forms and numerous mechanical changes made in the form, proportion and arrangement of its several parts within the spirit and scope of the invention as claimed. f
