J. P. LIMA DISPENSING DEVICE Filed June 29, 1935 Patented Feb. 2, 1937 DISPENSING DEVICE Jos Pereira Lima, Sao Paulo, Brazil Application June 29, 1935, Serial No. ,29,147 In Brazil July 6, 1934 3 Claims.

This invention relates to improvements in lloor-waxcrs or polishers comprising a rigid tube, formed of two readily assembled pieces, conveniently bent, and having on its upper end a con- 5 tainer for liquid wax or varnish and a mechanism to supply the wax or varnish, when desired and in suitable quantities, to a removable felt placed at the lower end of the tube in a reinforced and removable piece provided with a removable de- `1|) vice for distributing the liquid over the felt.- This apparatus may or may not be provided with a. handle for facilitating its use when waxing or polishing iioors. It will be seen from the above that this inven- 5' tion has the advantage of sparing its operator the necessity of dirtying his hands with wax or varnish inasmuch as either substance is poured in a liquid condition into the container before starting the work and this liquid is fed in desired y quantities through the feeding mechanism, to the felt for application on the floor.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like charactersA denote corresponding parts in the several views, and in which- Figure 1 illustrates a side elevation of the complete apparatus;

Figure 2 illustrates a longitudinal section of the upper part of the apparatus showing the container of the liquid substance for waxing or polishing and the mechanism to supply wax or varnish in suitable quantities;

Figure 3 is a longitudinal section through the .35 lower part of the device; and j Figure 4 is a section on the line F-A-F of Figure 3.

Referring to the drawing, Figure 1 shows at A the two piece tube conveniently bent; B denotes 0 the container; C the reinforced piece provided with the waxing or polishing felt D. For portability, tube A is formed of two pieces a and b for simple and easy assembling. The container B (Figure 2) has a hermetic 45 cover and a special internal device provided with valves permitting intermittent discharge of a certain amount of liquid wax or varnish. In the center of the cover there is a hole in which is tted the piece I of valve 2, which also acts as a 50 guide to 'button 3 fixed to the upper end of tube 4. By a slight pressure upon button 3 outside air is admitted into container B through a space between the said piece I and button 3. At` the b ottom of container B another hole is provided,

55 through which passes tube 5 which controls the (Cl. l2.21-114) amount of liquid to be released. Valve l2, which may be made of metal or hard fibre and provided with a feltor leather washer, slides on tube 4 and is pressed against the piece I by means of a spring 6. Valves 1 and 8 are connected to one 5 another by the tube 9, the valve I being connected to the button by a tube 4. The tubes 4 and 5 are provided with ports I, II and III alfording communication between the container B and the lower part of the device. On the lower end of 10 tube 5 is screwed piece I8 which serves as a guide for stem II and at thesame time acts as a support for spring I2 which keeps valve 8 closed and, consequently, holds valve 'I open. 0n the upper part of tube 5 is also screwed piece I3, '15 which serves as a guide for tube 4 and as a support for spring 8 keeping valve 2 closed. Piece I3, in conjunction with sleeve I4, also holds to container B, the valve'assembly and the support I5 of handle E, there being provided leather or 20 ber washers between these parts to avoid leakage and thus forming a compact assembly. This complete assembly is secured to the tube A by a sleeve I4 wherein is iitted the upper partof the tube 5. 25

As shown in Figure 3, the lower part C' is provided with a tubular extension C wherein is tted the lower end of the tube A. From the body of the member C' the liquid flows to the distribution chamber I6 and thence, through screen I 1, it 30 spreads evenly over felt D which is fixed and pressed to the side walls of socket I8 by the movable piece I9 which hinges on an axis, fixed to one of the side walls of socket I8, and is fixed to the opposite wall by means of a bolt, thereby permitting quick and easy removal and replacement of the felt `when a different colour of wax or var-` nish is to be used. x

In orderto make easier and handier the use of this apparatus, a handle E may be employed which will enable the operator to stand up and handle the apparatus with one hand only without having to stoop to open the valve.

According to this invention, the operation of the apparatus will be as follows: 'I'he apparatus 45 is held with the left hand by handle E, resting felt D on the floor to be waxed or polished, and with the right hand the cover of the container B is held and given a slight rotation movement leftward and lifted thereby disconnecting it completely from the apparatus; the container is then filled with the waxing or polishing liquid Y up to the level of vent I in tube E; the cover is again placed over the container so that the bayonet slots 28 of the container engage the pins 55 able devices.

pressed downward, then immediately relaxed, and, by holding the apparatus by handle E with the right hand, felt D` is brushed over the iloor to be waxed or polished. I

When pressing button 3, which moves simultaneously the three valves, valve 2 opens admitting air into container B through the space between the button 'and the piece I; at the same time valve 1 closes, thereby limiting the discharge to the quantity contained in the tube 5, and valve 8 opens releasing the liquid' contained in tube 5. When button l is released, valves 2 and l close and valve 1 opens .thereby lling up tube 5 again and in this way it'is again' ready to feed another supply of liquid.

The liquidl from tube 5 is led through tube A to chamber I6 and thence to felt D after passing through screen ,|1, which distributes same evenly over felt D, which in turn distributes the liquid quickly and periectly'over the iioor to be waxed or polished. Y

When the first supply of liquid is distributed and exhausted, button 3 should again be pressed and relaxed in order to again molsten felt D, and so on until the waxing or polishing of the iioor is completed.
