before any embodiments of the invention are explained in detail , it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings . the invention is capable of other embodiments and of being practiced or of being carried out in various ways . as shown in fig1 - 8 , the floor finish applicator generally 10 includes a cart 12 with a u - shaped tubular handle member 14 joined to a molded plastic base portion 16 with wheels 18 rotatably mounted thereon . a box 21 with a bag 23 containing floor finish is supported in housing 16 which provides a carrier member for the box 21 . a kickstand 22 supports base portion 16 of cart 12 . a spring 60 pivotally biases kickstand 22 toward the housing 16 . connected to the housing 16 is a frame member 20 with clamps 34 and 35 . a mop 28 having a handle 30 and a mop head 32 is removably attached to the frame member 20 by the clamps 34 and 35 . in a preferred manner , mop head 32 has a pad comprised of materials of different sizes for purpose of spreading and leveling the floor finish . it can be made of foam , flocked foam , woven or non - woven cloth . referring to fig3 , 6 & amp ; 7 a transmission assembly for transmitting power from the wheels to the pump 64 is shown . the transmission assembly includes a spring loaded clutch 38 for selectively controlling actuation of the pump 64 . the clutch includes a thrust washer 40 slideably received on drive shaft 42 . a spring 44 biases washer 40 against pivotal bar 48 . cable 66 is attached to pivotal bar 48 . a bevel gear 50 is connected to drive shaft 42 . the opposing end of drive shaft 42 is slideably received in drive shaft 52 which connects to pump 64 . a drive gear 54 is mounted on axle 56 . as seen in fig2 and 5 , cable 66 is also attached to bail 69 by the connecting peg 71 and is slideably secured in bracket 67 dispensed on handle 14 . bail 69 is pivotally attached to handle 14 . there is also a bail stop 73 connected to handle 14 . the pump 64 can include a variety of different pumps , such as piston pump , gear pump , diaphragm pump , peristaltic pump , and the like . while each pump can be utilized to deliver floor finish and can be operable via the transmission assembly described above , the peristaltic pump embodiment is a highly preferred embodiment . as explained in greater detail below , the peristaltic pump is preferred because it is substantially easier to clean since the floor finish does not contact the pump . referring to fig8 , the peristaltic pump is housed in compartment 75 . a floor finish feed conduit 25 is in fluid communication with the bag 23 by means of the connector 79 . feed conduit 25 is also in fluid communications with pump conduit 81 and is output conduit 83 . sleeves 85 provide connection between conduits 25 , 83 and pump conduit 81 . a spray conduit 87 with orifices 89 is attached to housing 16 by the brackets 90 . a further understanding of the floor finish applicator 10 can be had by a description of its operation as seen in fig1 - 8 . the bag 23 containing floor finish in placed in box 21 and the box loaded into the housing 16 of cart 12 as illustrated in fig1 . bag 23 is connected to flexible feed tube 25 as indicated in fig8 . mop 28 is clamped to the applicator 10 by means of clamps 28 and 29 , as shown in fig2 . when it is desired to dispense floor finish from bag 23 onto the floor surface 27 , the applicator 10 is moved in a direction indicated by the directional arrow 19 shown in fig2 . bail 69 is then moved in the direction shown by the directional arrow 17 , this causes pivotal bar 48 to move from the position shown in fig4 to that shown in fig6 whereby drive shaft 42 is moved by thrust washer 40 to move bevel gear 50 in engagement with drive gear 54 which is rotated by the rotation of axle 56 by wheels 18 . rotation of drive shaft 42 rotates drive shaft 52 through the pin 58 and slot 57 arrangement shown in fig7 . this affords linear movement of shaft 42 in shaft 52 while maintaining connection of the two shafts . rotation of shaft 52 effects a pumping action in pump 64 . as best seen in fig8 , floor finish flows through flexible feed conduit 25 into peristaltic pump 64 . it is pumped into output flexible conduit 83 and into spray conduit 87 where it is dispensed through orifices 89 . activation of the peristaltic pump 64 during movement of the cart 12 can be prevented by the roller clutch 94 in conjunction with wheels 18 . this is shown in fig5 . a roller bearing 92 is mounted on shaft 56 as is roller clutch 94 . a spacer 93 separates bearing 92 and housing 16 . in the event bail 69 is not moved to a position to place pivot bar 48 in the position shown in fig4 with the non - engagement of gears 50 and 54 , roller clutch prevents activation of pump 64 during movement of the cart 12 . an advantageous feature of some embodiments of the applicator is the disposable connector 79 and the disposable flexible conduits 25 , 81 , 83 and spray conduit 87 . when the application of the floor finish in complete , these components can be readily removed and replaced without any cleaning of the peristaltic pump 64 . in other words , through the use of a peristaltic pump , the floor finish never contacts the pump . as such , time consuming clean - up is not necessary . rather , the conduit is simply removed from the pump and replaced prior to next operation . another advantage of some embodiments the application 10 is the dual use of mop 28 . it acts as a spreader for the floor finish when attached to the cart 12 , yet allows use separately as a hand operated mop in order to apply floor finish to areas of floors not readily accessible when attached to the applicator . a roller clutch 94 has been described in conjunction with applicator 10 . if desired this could be eliminated as deactivation of the pump 64 can be effected during a forward motion of the applicator by placing bail 69 in the upward position shown in solid lines in fig2 . neither is it essential to have the mop 28 disengageable from the applicator 10 . all such and other modifications within the spirit of the invention are meant to be within the scope as defined by the appended claims . thus , the invention provides , among other things , a floor finish applicator . various features and advantages of the invention are set forth in the following claims .
a pull - behind floor finish applicator wherein a peristaltic pump is employed in conjunction with disposable conduit tubing obviate any clean up of the pump . this applicator is adaptable to receiving bag in the box floor finish , thus reducing cleaning time . the applicator employs a minimum number of disposable parts thus making it economical to produce . a mop is employed to apply floor finish to easily accessible areas in one instance , yet allows the mop to be used independently for application of floor finish to not so easily accessible areas .
