The present invention refers to a spreader of floor paste wax.
In known appliances for spreading floor wax, various objections are prevalent. Those adapted for use with liquid waX usually consist of a container at the lower end of a handle and a valve which regulates the outlet of the liquid wax. This valve, however, is located at the container, so that the person using the wax spreader must often stoop, in order to increase the opening of the valve as the liquid wax in the container is consumed. Another disadvantage of such appliances is the fact that liquid wax frequency squirts, staining the Walls and furniture of the rooms being waxed.
In order to eliminate these inconveniences, I have designed a type of spreader for use with paste Wax which is the object of the pre-sent invention.
The invention consists, essentially, of a container provided with a piston, the rod of this piston being enclosed in a tube and being connected to a toothed rack bar, the said tube eX- tending into a handle and being provided with a hand lever operating on a trigger which engages the teeth of the rack.
The invention further includes certain particular details of construction, such as: a hook to withdraw the piston when desired, a tie-rod to release the trigger in order to permit the free I withdrawal of the piston, a set screw holding the piston rod tube to the wax container, a cover provided with a hinge and a, latch to close the wax container, an elongated mouthpiece with a length-wise wax outlet opening provided with felt spreaders and which may be closed by a removable plug, and a small receptacle into which the said mouthpiece is inserted when the iioor wax spreader is not in use.
The oor wax spreader of the present invention is illustrated on the accompanying drawings in its preferred form of embodiment. In said drawings Figure 1 represents a side elevation view of the door wax spreader;
Figure la is a perspective View of the receptacle for receiving the mouthpiece of the applicator during storage;
Figure 2 shows a plan view of same spreader; and
Figures 3 and 4 are vertical cross-sections of its handle end and its wax container end, respectively.
Figure 5 is a perspective view of the wax spreader. f
(c1. sii- 25) In the accompanying drawings, I is the wax container with the top portion extended to form the mouthpiece 2 and with its opposite end provided with a cover 3 hinged at 4 and closed by 5 a latch 5'. From said cover 3 two concentric tubular extensions 6 and I are provided, between which the end section 9 of a tube is inserted and tightened in place by the set screw e; the said tube consists of three sections 9, IB and II, with lo threaded ends, the second section (I9) being provided with a longitudinal notch I2, while the third section (I I) is provided with a` lower opening I 3 and two upper holes I4 and has its free end bent downwards to form the handle I E which is provided with a rubber sleeve I6.
A piston I1 i-s provided inside of the container I, the rod of this piston passing through the eX- tension 1, which serves as its guide, and through the tubular sections 9 and I0, said piston rod consisting of two sections I8 and I9 connected to each other, the second section (I9) being provided with a hook 2li which projects through the notch I2 of tube I0. This second section I9 is connected to the end of a rack 2| which is enclosed in tubular section II and is held in place by the to a trigger 21 which engages the teeth of the rack 2 I. 'Ihe lower end of the hand lever 25, the pivot member 24 and the trigger 21, as Well as the lower half portion of opening I3 may be enclosed by a triangular cover 28 which is iixed to the tubular section II by means of a screw 29. In
order to release the trigger 21 when desired, a special device is provided which consists of a double tie-rod 30 passing through the two upper holes I4 of tubular section II and through a hole in the trigger; the outer end of this device is provided with a hollow push-button 3|, and a spring 32 which fits against tubular section II, between the holes I4, and tends to maintain the trigger 21 in engagement with the teeth of the rack 2 I The mouthpiece 2 is provided with flanges 33 to receive the felt pieces 34 which serve to spread the paste wax 31; the outlet opening of said mouthpiece may be closed by a removable plug 35. When the lioor wax spreader is not in use,
the mouthpiece 2 is inserted in a receptacle 36,
shown in Figure 1a, in order to collect any of the wax 31 which may come out of the mouthpiece 2 and to prevent soiling the place where the spreader is kept.
The floor wax spreader of the present invention operates as follows: In order to fill the wax container I, latch 5 is released, piston I1 withdrawn within the cover 3 and the cover opened. The container I is then iilled with paste wax and, after that, cover 3 is again closed and fastened with latch 5. The spreader is then held by its rubber handle IE-I and laid against the iioor so that the two felt pieces 34 are in the position shown on Fig. 1. The spreading of the wax on the i'loor may then be started; for this purpose, the hand lever 25 is squeezed towards the handle I5, by which movement the link member 24 pushes forward the trigger 21 which engages one of the teeth of rack 2 I, which in turn drives forward the rod lil- I9 of piston I l, pressing said piston against the wax 3l in the container I, and forcing said wax to come out through the mouthpiece 2 between felt pieces 34. By sliding the apparatus against the licor, with a back-andforth movement, and by operating the hand lever 25 from time to time so that the wax will gradually come out through the mouthpiece 2, the spreading of the wax over the iloor is easily performed. When all the wax in the container is consumed, in which case the piston l'l is at the bottom of container I, the button 3| is pushed downwards forcing the double tie-rod 30 to depress th-e trigger .27, which is thus disengaged from the teeth of the saw rack 2i, permitting the l piston rod I8--I9 and the saw rack 2l to be freely moved back to their starting position by means of the hook 20. The push-button 3! is then released, and the operation of the spreader may be started again, after reiilling the wax container I as described above.
1. A iioor paste dispenser comprising a sectional tubular handle portion, a dispensing container at the lower end of said handle portion adapted to contain paste wax, a-piston within said. container, a piston rod connected to said piston and extending into said handle portion, a toothed rack bar contained in said handle portion, means connecting said piston rod to said rack bar, a hand lever pivotally `connected to said handle portion, and a'trigger operatively connected to said lever and to said rack and adapted to impart a step by step dispensing movement to said piston and to the wax in said container, the dispensing container being provided with a hinged cover, said cover being provided with an inner and an outer concentric tubular extension, said tubular handle being received between said concentric tubes and secured thereto by means carried by the outer concentric tube, the inner concentric tube receiving the piston rod and acting as a guide therefor.
2. The construction of claim 1, in which one of the sections of the tubular handle portion is provided with a lower longitudinal notch and a downwardly curved portion, a housing secured around the lower longitudinal notch to receive the operative connections of the trigger and rack, and another section provided with an upper 1ongitudinal'notch, a hook connected to said piston rod and projecting through said upper notch.
3. The construction of claim 1, in which one of said sections of said handle is provided with a lower longitudinal opening and spaced upper openings, a, casing secured about said lower opening, a hand lever pivotally connected to the casing and spaced from the handle portion, a spring maintaining the spaced relationship, a 1ink member within the casing, a trigger pivotally connected to said link member, a push button connected to said trigger and projecting through said spaced openings, and a spring on said push button normally retaining said trigger in engagement with said rack bar.
