FILTERING AND DECANTING APPARATUS.
Specification of Letters Patent.
Patented Feb. 15, 1921.
Application filed. December a, 1919. Serial No. 341,912.
1 0 all who 12bit may concern:
Be it known that I, BENJAMIN H. BEN- NETTS, a citizen of the United States, and resident of the city of Tacoma, county of Pierce, and State of \Vashington, have in-- efficient, which requires a minimum amount of personal time and attention, and whereby danger to the breakable apparatus and sometimes resultant danger to the operator is practically eliminated.
It is also an object of the invention to provide filteringapparatus whereby handling of the receptaclescontaining the solutions to be filtered, is not required after the beaker-s are once placed in position within the apparatus, and whereby the sediment or precipitate which may be contained within the beakers is in the least disturbed until such time when it is desired that it be washed into the filters.
A further object of the invention is to provide apparatus of the above character that may be adjust-ed for the accommodation of beakers and funnels of various sizes, and
to provide a control mechanism for the beaker tilting and supportingshelf whereby the solutions may be poured from the beakers into filtering funnels at any desired or required speed or in any quantity needed.
In accomplishing these and other ObJBClS of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Figure 1; is a perspective: view of a filtering and decanting apparatus constructedaccord ing to the present invention, showing the apparatus in use.
Fig. 2 is a transverse, vertical section of the same. I
Fig. 3 is a front view of one end of the apparatus. I
- .Fig. 4: is a detail view, illustrating the means for adjustablyand yieldingly supporting thebeakercl'amping bar.
. frame 7.
Referring more in detail to the drawings-- 1 designates a supporting shelf whereon a plurahty'of beakers 2, containing solutions to be filtered, may be placed. This shelf comprises a front portion 1( that is fixed perpendicularly to the base, against which the beakers may be clamped, during a filter- 111 operation, as will presently be described.
ured to the outer side of the shelf front 1, at the opposite ends thereof, are hangers 3, each provided with a plurality of downwardly opening notches l adapted to receive the outer ends of supporting pins 5 that. extend laterally from the upper ends of standards 6 fixed to the ends of a supporting The standards 6 are provided with longitudinal slots 6 through which the shank of a clamping bolt 8 is ext-ended to clamp the standard to' the end, or leg, 1.0 of the frame 7 at any adjusted position within the limits of the slot. l
The shelf is swingingly supported by these hangers 3 and by means of a pair of cables 12 which are fixed at their ends to the under side of the shelf and are wound upon spirally grooved drums 13' fixed on a winding shaft ll supported revolubly at the upper ends of standards 15 that are also carried by the end members ofthe supporting frame 7 as is particularly shown in Fig. 1.
The shaft ll is provided at its ends with winding cranks lowhereby it may be revolved to swing the shelf upwardly on its mountings to tilt the beakers, that may be mounted thereon, into pouring position. A small ratchet wheel 19 is fixed to the shaft. adjacent one end and a pawl 20 is pivotally mounted on a standard 15 to engage therewith to prevent unwinding of the cables from the drums so that the shelf may be retained at any adjusted position.
The standards are each provided with a forwardly directedmember 15 which is slotted to slidably receive a clamping screw 21 and a guide pin 22 to hold the standards substantially vertical and at the same time-permit them to be adjusted forwardly or rearwardly in accordance with the adjustment of the standards 6 or the positioningi of the han ers 3 on thesupporting pins 5.
ounted at the front of the" frame, in parallel relation-with-the shelf 1, is'a funnel supporting bar 25. This bar is provided with a plurality of downwardly tapering 'apertures27, spaced in accordance withthe spacing of the beakers on the shelf 1, through which funnels 28 may be extended; the upper ends of the funnels being in such position as to receive the contents of the beakers 2 and their lower endsjbeing disposed above receiving beakers 30 which catch the filtered solution.
The bar 25 is also .adj ustablysupported by means of arms 32 provided with slots for receiving clamping bolts 34 which may be loosened to permit adjustment of the funnel supporting bar to a position'to accommodate different sizes of beakers.
The means employed for spacing and re-- taining the beakers on the-shelf 1 dur ng a filtering process consists of a bar bent in a series of corrugations which receive the outer walls of the beaker-s to space them at regular intervals according to the spacing of the funnels. This bar is ,yieldingly clamped against the beakers by means of ring end with a series of closely spaced lugs 43 which may be moved through the bar slots to engage the outer face of the bar to adjust the same inwardly to hold different sizes of beakers.
Assuming that the apparatus is so constructed, in using the same for filtering purposes, the beakers containing the solution, or solutions to be filtered'are first clamped on the shelf 1 while it assumes a position similar to that shown in dotted lines in Fig. 2. The funnels containing the filtering paper, and the receiving'beakers, are then placed in receiving position by an adjust ment, if necessary, of the bar 35.
The operator then winds the cables 12 on the drums 13 to swing the shelf upwardly on its mounting, sothat the beakers will be slightly tilted and some of the solution is poured into the 'funnels,wherefrom it may filter into the receiving vessels.
If the filtering is slow, the beakers may I be retained in this positionqbeing held by the cableswhich are prevented from unwinding by the pawl which engages the ratchet wheel fixed on the shaft 14:, and the operator 1 in the meanwhile may go on about other work.
' After this first funnel full has been filtered, the operator winds the cables in a little farther to pour more of the solution into thefiltering funnels. This performance is repeated as oftenas necessary or desired, until the beakers emptied, If Sediment tacles of various sizes and that filtering orv decanting is effected in an easy, efficient, safe, and time saving manner.
Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent, is:
1. In a device of the character described, a frame structure comprising a horizontal bar for the support of receiving vessels, a shelf disposed in parallel relation to said bar whereon dispensing receptacles may be removably supported, hangers pivotally and adjustably fixed to the, frame and to the shelf to swingingly support the latter, means for actuating the shelf to tilt recep tacles that may be supported thereon, to dispense their contents into receiving vessels that may be'supported by the said bar.
