'7 Claims. (01. 312-51) This invention relates to a novel dispenser for holding a plurality of cloth pads or the like and more especially filter pads and provided with dispensing mechanism for dispensing the pads one by one.
More particularly, it is an aim of the present invention to provide a novel container for holding a stack of pads and having manually operative dispensing means for extracting the bottommost pad from the container. I
A further object of the invention is to provide a novel means of extremely simple construction for performing the dispensing operation when a hinged bottom portion of the container is swung downwardly and toward an open position.
Another and important object of the invention is to provide a quick demountable bracket support for the container to enable the container to be readily demounted from the support for refilling the container and be readily repositioned on the support and in substantially an upright position.
Still a further object of the invention is to provide a dispenser having a novel pivoted hook structure for engaging and extracting a filter cloth or pad from the bottom of the stack contained in the receptacle.
Still another object of the invention is to provide a receptacle having novel means to maintain the pads or filter cloths in a dry condition when the exterior of the container or receptacle is rendered moist by sweating or humidity.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and, wherein:
Figure l is a bottom plan View of the receptacle and dispenser;
Figure 2 is a fragmentary vertical sectional view thereof taken substantially along a plane as indicated by the line 2-4. of Figure 1;
Figure 3 is a front elevational view of the bottom section of the receptacle supporting bracket and with the receptacle removed therefrom;
Figure 4 is a horizontal sectional view thereof taken substantially along a plane as indicated by the line 4-4 of Figure 3;
Figure 5 is a fragmentary sectional view showing afabric pad or filter cloth engaged by the hook structure of the dispensing apparatus and as it will appear while being removed from the bottom portion of the receptacle, and
Figure 6 is a fragmentary vertical sectional 2 view taken substantially along a plane as indicated by the line 66 of Figure 1.
Referring more specifically to the drawing, the cloth dispenser in its entirety and comprising the invention is designated generally I and includes a container or receptacle, designated generally 8, a dispensing apparatus, designated generally 9 and constituting a swingably mounted part of the bottom of the container 8 and a mounting bracket I0 for the container 8.
The cloth or pad dispenser 1 has been illustrated in the drawing and will be described in connection with conventional fabric pads or filter cloths such as are employed in stables for filtering milk being poured into cans, not shown, in which the milk is transported to dairies. Such filter cloths or pads, a plurality of which are illustrated in Figure 2 and each designated generally ll, ordinarily include a multiplicity of plies including a number of upper plies of cotton I2 and a bottom ply of an open mesh fabric 13 such as cheesecloth. As said filter cloths or pads II are generally disk-shaped to fit the bottom of a milk strainer for filtering the milk as it is poured into the milk can, the cloths or pads ll have been so illustrated in the drawing and the container or receptacle 8 has been illustrated as being circular in cross section; however, as the description proceeds it will be readily apparent that the pads or cloths l I could be of various shapes and that the container 8 could be of various shapes in cross. section to accommodate it to the shape of the cloths or pads. It will also become apparent as the description proceeds that the container and dispenser unit 1 could equally well be employed for holding other pieces of fabric to be dispensed singularly from the bottom thereof.
As previously stated, the receptable or container 8 is shown provided with a cylindrical wall l4 having an upper edge turned inwardly and back upon itself to provide an internal bead l5 and a lower edge which is likewise turned inwardly and back upon itself but which has the turned back portion inwardly spaced to provide an upwardly opening channel [6 for receiving the depending annular flange ll of a ring, designated generally 18 which is supported therein and which likewise includes an annular inwardly extending flange I9 which forms a part of the bottom of the container 8 and which provides a relatively large opening in the bottom portion of said container. As previously stated, the filter cloths or pads ll are stacked in the container 8 and are applied thereto through the 3 open top thereof and will be supported therein by engagement of the outer part of the lowermost pad II on the inwardly extending annular flange or bottom portion I 9.
As seen in Figure 2, a portion of the channel I 6 is cut away as indicated at 29 to accommodate a portion of a bar 2| which is fastened to a portion of the depending flange I! by a rivet or other fastening 22 which also extends through the cylindrical wall I4. The bar 2| has an inturned portion fastened to the underside of a portion of the inwardly extending flange I9 by another rivet or fastening 23.
stricted downturned rolled portion forming a hinged barrel 24 which forms one leaf of a hinge, designated generally 25- and whichalso includes a leaf 2%; having spaced barrels 21 between which the hinged barrel 24- is disposed and which barrels accommodate a hinge pin 28. The leaf 2B: is-sec'ured to the underside of a disk 29 by a fastening 39-; said disk 29 being of a size to completely cover the opening in the bottom of the container 8 as defined by the annular flange l9 and having its outer portion normally disposed against the underside of said flange l9.
An elongated strip 3|, preferably formed of a relatively resilient metal, is secured to the under side of the disk 29 by a rivet or other fastening 3| a at a point remote to the hinge leaf 26 and substantially in diametrical alignment therewith. The strip 3| is provided with an elongated free end portion which extends outwardly with respect to the periphery of the disk 29 and which is provided with a downwardly offset portion 32 which extends around a portion of the channel IS, an upwardly extending portion 33 which is disposed externally of a part of the cylindrical wall l4 and an outwardly and downwardly curved terminal portion forming a handle 34. A rivet 35 connects a portion of the wall M to a portion of the flange l1 and has a headed outer end which is engaged by an outwardly bowed part of the portion 33 to combine therewith to form a spring latch for releasably retaining the disk 29 against the underside of the flange I9, as illustrated in Figure 2 and it will be readily ap-' parent that the handle 34 can be grasped and pulled outwardly to disengage the portion 33 from the rivet head and so that the disk 29 can be swung downwardly with respect to the bottom of the container 3 to and beyond its dotted line position of Figure 2. It will likewise be readily apparent that the handle 34 can be grasped for returning the disk or hinged bottom 29 to its full line position of Figure 2 and that the portion 33 as it reaches its position of Figure 2 will snap into engagement with the rivet head for automatically latching said disk or bottom 29 in a position for closin the open bottom of the container 8.
As best illustrated in Figure 1, the disk 29 is provided with an elongated opening 36 which is disposed in alignment with the hinge leaf 26 and strip 30. The opposite, inner end of the strip 30 is bifurcated and the furcations thereof are turned to provide aligned, spaced hinge barrels 31 which are disposed beneath one end of the opening 36. An elongated plate or strip 38 is disposed normally against a portion of the upper surface of the disk 29 over a portion of the opening 38 and is preferably of a width greater than the width of said opening. Said plate 38 has a restricted extension or shank 39 at one end thereof which extends downwardly Said last men-- tioned portion of the bar 2| terminates in a re wardly extending portions 54 of said arms.
through the opening 33 and which terminates in a hinge barrel 49, as best seen in Figure 1, which is disposed between the barrel portions 31 for receiving a hinge pin 4|. The opposite end of the plate 38, which extends in a direction toward the hinge 25 is notched to provide a plurality of laterally spaced tapered prongs 42 which are curved upwardly and backwardly and which combine to form a multi-pronged hook or claw.
Said plate'or strip 38, adjacent the end thereof from which the shank 39 projects, is provided with two longitudinally spaced openings 43 which are loosely engaged by an eye or loop 44 formed on one end of a rod 45 which end extends'out'wardly and upwardly through the opening 36. Said rod 45 is provided with a laterally turned opposite end 46 which is journaled in a sleeve 41 formed by looping the depending, first mentioned end of the strip 2|.
The container or receptacle- 8- is adapted to be' demountably supported in an upright position ona vertical wall surface 48- and which is accomplished by the bracket I9 which includes a bottom bracket section, designated generally 49 and a topbracket section, designated generally 59. Thebracket section 49-, as best illustrated in Figures 3 and 4, includes a plate'which is secured by fastenings 5| to the surface 48 and which is provided with laterally spaced corresponding supporting arms 52 which form integral' portions of the plate and which extend outwardly therefrom in a direction away from the wall 43 and which have upwardly extending outwardly ofiset' portions which terminate in outturned shoulders 53. The arms 52 are spaced a sufiicient distance apart to straddle the downwardly extending portion of the strip 2| and portions of channel l6 rest on the lower out- The upwardly extending portions of the arms 52 engage the inner side of the channel H5 and the shoulders 53- thereof bear against portions of the underside of the flange IS. The upper bracket 59 comprises a plate having a lower portion which is disposed against the wall surface 48 and secured thereto by fastenings 55. Said plate is provided with an outwardly offset intermediate portion 56 which engages against a portion of the outer side of the cylinder |4 adjacent its upper edge and which is bowed to fit substantially fiush thereagainst and has an inwardly extending upper edge portion 57 which overlies a portion of the bead l5 and which extends inwardly with respect thereto.
The receptacle or container 8 is provided with a flanged closure 58 for the open top thereof and which is provided with an outwardly offset peripheral portion 59 which fits around the outer side of the plate portion 56 to retain the receptacle 8' in engagement with the upper bracket section 50 when the cover 58 is applied and which likewise functions to retain the receptacle in engagement with the lower bracket section 49.
It will be readily apparent that the receptacle 8 can be refilled conveniently by removing it from its position on the upright surface 48 and which is accomplished by removing the cover 58 after which the receptacle 8 can be swung outwardly and downwardly away from the bracket section 50 and thereafter lifted off of the bracket section 49. After refilling the container 8 the aforementioned operation is reversed for reapplying the receptacle to the supporting bracket l9 and said receptacle is detachably secured in position thereon by the final operation of reapplying the cover 58, as previously described.
It will be readily apparent that when one or more of the filter cloths or pads II are contained in the receptacle 8, as illustrated in Figure 2, that the bottommost filter cloth or pad may be extracted from the opening defined by the flange [9 by grasping the handle 34 to swing the disk or bottom 29 downwardly on the hinge 25, as previously described. When this occurs, and as illustrated in Figure 2, the rod 45 will prevent the plate 38 from swinging downwardly with the disk 28 during its initial movement and instead will cause the plate 38 to assume its dotted line position of Figure 2 and to continue to swin in a clockwise direction relatively to the pivot pin 4| so that the prongs or claw 42 which engages the bottommost pad H to extract said pad downwardly through the opening defined by the flange l9 and will move said pad outwardly with respect to the receptacle 8 or in a direction from left to right of Figure 2. It will thus be readily apparent that the dispensing apparatus 9 will function each time that the disk or bottom 29 is swung downwardly from its full line position of Figure 2 to extract the bottommost cloth or pad I I from the receptacle 8 and deliver it outwardly so that it can be readily grasped. As the bottom 29 is returned to its normal, closed full line position of Figure 2 the prongs or claw 42 will penetrate the next pad or cloth which is then disposed in a bottommost position preparatory to extracting said pad the next time that the bottom is swung downwardly.
The annular portion of the container 8 disposed below the level of the flange l9 will function in combination with the cover 58 to keep the pads or cloths H in a dry and sanitary condition and to prevent moisture caused by humidity within a barn or stable and which collect on the exterior of the receptacle 8 from reaching the pads ll.
