plate I 2 and a bottom pad I3. The casing I0, Cotter pins 3a extend through the stem 29 of 45 which is preferably made .of aluminum to reduce the valve, just above and below the arm 3l, for its weight, contains a tank I4. The bottom I5 of .transmitting movement ofthe arrn 3! to the stem this tank is` spaced somewhat above thelower 29. The spring 35 acts through the arm SAI, shaft edge IS of the casing, and the casing below the 32 and arm '3l to hold the valve 2B yieldingly bottom I5 of the tank is characterized by a against the seat 25. When it isdesired to release 50 downwardly extending flange Il of elongated some of the wax or other liquid the valve 28 is rectangular form. The handle I I is pivotally atlifted from the seat 2S by af flBXible Wir@ 3T WhCh tached by bolts I8 to ears I9 on the lower poris connected to the arm 36 and extends through a tion of the back of the casing and is movable from flexible guide conduit 38 from the casing up ,into
the inclined operating position shown in Fig. 1 the handle l l. At the upper end of the handle the 55 wire 31 is connected with a trigger-like finger piece 39 which when pulled will move the Wire 31 and open the valve 28 against the resistance of the spring 35. 'Ihe .offset of the pivot I8 for the handle with respect to the point 4B at which the conduit 38 enters the casing is such as to force a certain amount of slack in the wire 3'I when the handle I I is moved into its straight up out-of-use position, and this slack is suiicient to prevent the valve 28 from being operated by the finger piece 39 when the handle is in that position, thereby eliminating the possibility of any inadvertent openingof the valve when the applicator is not actually in use.
The plate I2 is of the same rectangular shape as the flange I'I which extends about the lower portionof the casing, and underlies the edge I6 of the ange Il, closing the otherwise open bottom of the casing between the elevated bottom I of the tank I4 and the lower edge I6 of the flange. This bottom plate, like the casing Ill, is preferably made of aluminum and is characterized by an upwardly opening trough 4I which eX- tends substantially from one end of the plate to the other. This trough is centered beneath the valve 2B and slopes downwardly from its center toward each of its ends, which ends 42 and 43 are closed.` The trough 4I is provided at regular intervals in its bottom with small ports 44. The bottom plate I2 is provided, directly beneath the ported bottom of the trough 4I, with a downwardly opening channel 45 into which the Wax or other liquid is metered, and is provided, at opposite sides of the trough adjacent the longer side flanges Il, with upwardly and outwardly inclined flanges 46 for centering the' bottom plate within the open bottom of the casing.
The bottom pad I3 is a rectangular piece of material, preferably lambs wool. This pad is positioned against the under surface of the bottom plate I2 and is characterized by extensions 4'I along its longer sides which are folded back about the longer sides of the bottom plate and tucked beneath the centering flanges 46. The pad I3 e is held in this position by being clamped between the upper edges of the plate I2 and the lower edge I6 of the casing at the bottom of the flange I'I; The plate I2 is removably held in this clamped position by the engagement of a lug 48 on one end of the plate with an underlying lug 49 on the corresponding end of the casing. The other end of the plate is held by a pin 50 in the casing which extends into an aperture 5I in the plate. The bottom pad I3 is provided at intervals longitudinally of the center of the same with apertures 52. These apertures are located directly below the distributing channel 45 in the bottom plate, preferably in vertical register with the ports 44 in the bottom of the trough 4I.
1. A liquid applicator of the type described, comprising a casing having a tank in the upper portion thereof and a downwardly opening recess beneath the tank, a valve in the bottom of the tank, a readily removable bottom plate beneath the lower edge of the casing over the recess, an apertured trough on the bottom plate Within the recess below the valve, and a pad beneath the bottom plate provided with reversely bent opposite edge portions which are releasably clamped between the lower edge of the casing and the bottom plate.
2. A liquid applicator of the type described, comprising a casing having a tank in the upper portion thereof and a downwardly opening recess beneath the tank, a valve in, thebottom of the tank, a bottom plate beneath the lower edge of the casing over the recess, an apertured trough on the bottom plate within the recess below the valve, and a pad beneath the bottom plate, said trough being inclined downwardly trom its center toward its ends, said bottom plate being p`r0- vided beneath the trough with a downwardly opening distributing channel, and said pad extending across said channel.
3. A liquid applicator of the type described, comprising a casing having a tank therein, an apertured bottom plate beneath the tank, a pad beneath the bottom plate, a valve in the bottom of the tank above the apertured bottom plate, a manipulating handle movable from an upright out-of-service position to an inclined operating position, a linger piece on the handle connected with the valve for opening the latter, and means for preventing opening of the valve bythe nger piece when the handle is in its upright position.
