RICHARD o. OONGDON, or. PHILADELPHIA, PENNSYLVANIA.
FILTER-PRESS.
SPECIFICATION forming part of Letters Patent No.j672,592, dated April 23. 1901.
l Application filed January 2, 1901. Serial No. 41,769. (Nomodeh) To a whom it may concern..- ,Be it known that I, RICHARD O. CoNGDoN,
a citizen of the United States, residing at 1 Philadelphia, in the county of Philadelphia andState of Pennsylvania, haveinvented certain new and useful Improvementsin Filter Presses, of which the following is a specification. A
One object of the presentinvention is to in- IO su re in practice the theoretical or ideal work- 5. removal of the filtrate or residuum.
3 Other objects are hereinafter set forth.
To these and other ends hereinafter set forth the invention, stated in general terms,
, consists of the improvements in the rings and also in the improvements in the combination r of the improved rings with the filter-blankets and .offtakes,which are hereinafter more fully described and claimed.
The nature, characteristic features, and
scope of the invention will be morefully un- 1 derstood from the following descriptiomtaken in connection with the accompanying drawings, forming part hereof, and in which Figure 1 is a view showing one embodiment of myinvention and illustrating a section through a part of one of the rings, one of the platens of the press, and one of the ring-separators, consisting of a central supporting-plate, two perforated plates, and a I pair of blankets, all securely fastened together with rivets. Fig. 2 is a face view of one of the rings embodying features of my invention, showing one of the separators with portions thereof broken away. Fig. 3 is a transverse sectional view showing two rings embodying features of the invention, with the separators mounted between them, in accordance with my invention. Figs. 4 and 5 are respectively side and end views of 345 a filter-press embodying features of the invention. Fig. 6 is a transverse sectional view showing means for covering the gutter and illustrating features of the invention; and Fig. 7 is a View illustrating features of the invention, showing means for adjusting the length of the gutter.
In the drawings, 1 represents the rings, and 2 represents the separators. The rings and the separators are, as is well known, mountedbetween the fixed platen 3- and the movable platen 4 and are arranged alternately. As usual, the separators have centralopenings 5, and the material to be filtered is introduced under pressure by way of the pipe 6. The filtered material is expressed from the rings and the residuum is retained in them. Each ring 1 is provided with a seat 7, which packs the blanket, and it is also provided with a second seat 8, which also packs the blanket. Between these faces there is provided a groove or channel 9, which extends all the way around the ring. The outside diameter of'the ring should be substantially equal to or less than the diameter of the supporting-plate 10 in order to allow the portion 8 of the ring to form a joint with the canvas 11 of the separator. The periphery of the perforated plate 12 should come substantially flush with the inner edge of the groove 9. The thickness of the plates 12 afiords a joint between the separator and the parts 7 of the ring, which joint, however, is tighter than the joint formed between the parts 8 of the ring and the reinforced edge of the canvases and the support-plate 10, because the plates 12 do not extend between the parts 8. Around the periphery of the perforated plates there is a channel 13 for filtered material.
This channel is formed between the reinforced edge of the canvas, the perforated plates, and the supporting-plate 10. The filtered material reaches this channel 13, and in order to do so it penetrates the canvas and finds its way through and past the perforated plate 12. A serious defect which is remedied by the present invention is that unfiltered material, under the great pressure to which it is subjected, is forced between the seat or face 7 and the canvas. Hitherto such material squirted from the machine and filew all 95 around the place. However, in the present invention such material reaches the groove 9 and is there confined and collected. At the base of the rings and of the blankets provision is made for carrying off the filtered material from the channel 13, as well as the un "filtered material which may have reached the groove 9. Of courseunfiltered'material does not reach the groove 9 in anythinglike the quantity that filtered material reaches the [with the filtered material is-,-by reason of the small proportioiii, negligible. The advantage of preventing theescape of streams of material from the machineis obvious in all cases, and it is" especially marked where the fluid acted upon is sticky and dirty or isinjurious A provided with an annular groove having anto-theeyes and personal safety-of the workmen. I Provision is made to lead off the ma- 9 in a proper manner'and predetermined dishown in the drawings, the rings are pro- .vided at their lower portions with reinforce:
ments 17. These permit of the proper escape of the filtered material even when it is of a sticky nature, and at the same time they serve to reinforce the rings where the latter are more or less weakened by the presence of the openings 14; and 15. His located a gutter 18, into which they discharge and which leads the material to any suitable receptacle. The sediment or residuum remain'sin'the rings as cake and is knocked out of the rings in the usual manner. However, when it is knocked out the gutter may be covered, so that it does not receive any of the residuum. To cover the gutter, the latter may be provided with a hinged side, as 21, Fig. 6, which can be closed like a lid by means of the link and lever 22 or can be turned into upright position, so as to complete the gutter. The sides of the gutter may be made in sections 23 and 24 overlapped and connected by slot-andpin connections, so that the section 23 may be shifted in order to compensate for the shifting of the movable platen of the press. The residuum falls upon a suitable grate or pan 19, from which it is removed by the conveyer 20, for example,
through a doorway and entirely out of the building. The front and rear platens 3 and 4 are provided with annular grooves 9 and may have ofitakes 14*.
It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,
Having thus described the nature and ob- The Beneath the outlets- I jectsof my invention,what I claim as new,
and desire to secure by Letters Patent, is
I 1. Afilter-ring provided upon each of its faces with annular seats "having between them an annular groove, said groove extending all the way around the ring, substantially as described.
' 2; A filter-ring having upon. each of its faces annular groove that'extends allthe outlet for the" grooves, substantially as described.
3. In combination the filter-press platen nular seats upon opposite sides of the groove, a blanket, and means for supporting the blanfket in respect to the platen, substantially as described. V v e 3 r e '4. In combination filter-rings I provided upon their opposite faces with-an annular groove and with annular seats arranged on opposite sides ofthe groove, a'separator interposed between the rings and having its support-plate and canvases arranged between the outer seats and having its support-plate and perforated plates and can vases arranged between the inner seats, substantially as deand an annulargroove arranged between the seats and all around the ring, ofitakes at the bottoms of the rings, blankets between the rings, a gutter arranged under the olftakes, and a table or pan arranged beneath the gutter for the reception of the cake from the rings, substantially as described.
7. The combination in a filter-press of rings provided with outlets, a gutter arranged beneath the outlets and having a hinged side arranged to operate as a lid, and means for shifting the hinged side, substantially as described.
8. The combination in a filter-press of a movable and a fixed platen, rings provided with outlets, and a gutter arranged under the outlets and between the platens and consistin g of sections having sliding connection with each other, substantially as described.
In testimony whereof I have hereunto signed my name.
