The lower end of the container 2 is provided with an extended spout 4, and a rubber compression bulb l is attached to the other end of the solution container 2 at 3.

As described, compression of the bulb I, expels an amount of solution through the lower open end of the spout 4, at 5.

In order to locate the open end 5 of spout 4 and to hold it centrally to the crack while expelling solution from spout 4 while drawing the device along a crack, such as ll, Fig. 5, the lower end of spout 4 is provided with a tracking device or extension, generally denoted by 6, Figs. 1, '2 and 3.

In the form shown, the tracking means comprises a curved portion 6, having a curled, spout engaging means 1 which conforms to the diameter of the spout 4 at the point of attachment, and may be soldered thereto, at or adjacent to the angled spout end 5.

At substantially right angles to the curl 1 and at the opposite end of extension 6 is located a right angled bent flange or runner 8, and on its outer edge is a down bent short crack entering flange 9.

As indicated in Fig. 2, the ends of the runner and flange 9 are upturned as at I l-l4 for ease in sliding the attached tracking means to and fro when placing solution in a crack. As indicated by the dot and dash axis line AB, Fig. 3, the spout end 5 is so located in the tracking means that the axis of the spout end 5 coincides with axis AB, so that the crack flange 9 is in central alinement with the open spout end 5 when the device is registered in a crack, so that expelled solution from open spout end 5 is directly introduced in the open crack when the device is positioned as illustrated in Fig. 1, Where the crack flange 9 is shown dotted.

The operation of application of the solution is as follows, the container 2 is filled with the solution, the crack flange 9 entered into a crack, the implement comprised of parts I, 2, 4 and 6 is then moved along the crack to be treated, and, simultaneously, the bulb I 'is squeezed, to expel a continuous discharge of solution from spout end 5 into the crack, where, by capillary action it is immediately drawn into said crack as illustrated by the heavy lines I|-I I, between boards Ill-Ill Fig. 5. In this latter action the solution follows the contours of the tongue and groove contours I2|3, and thus, after the solvent becomes evaporated, the pores of the wood and the faces of the adjacent edges are filled and coated with a lubricant and a squeak silencing cushion, which does not dry out.

The application of the cold solution, to floor cracks at points on the floor where warping and consequent squeaks are developed, is rapid, clean, effective and is far superior to renailing such loose places, because, in time the nails pull loose and the squeak is accentuated.

By the present method and treatment the desired results are economically and permanently accomplished and the residual silencing coating in the cracks and in the pores of the wood remains permanently active.

Having thus described my invention what I claim is:

1. A method of silencing floor squeaks in a laid wooden flooring having cracks therein consisting of treating the squeaking portions thereof, through the associate cracks thereof with a solution comprising paraffin and rubber dissolved in a fluid volatile solvent.

2. A fluid for silencing squeaky portions of wooden flooring consisting in volume, of two and one quarter parts of a low-viscosity, volatile solvent fluid, one quarter part of paraffin and one and one quarter parts of dissolved rubber.

3. In combination, a floor having adjacent faces of adjacent boards coated with a mixture of one part of paraffin to five parts of rubber.

4. In combination, a floor having adjacent faces of adjacent boards coated with a dry, nongreasy, cushioning anti-squeak coating including a molecular mixture of paraffin and rubber.

5.' In combination, a floor having adjacent boards and tongue and groove joints between said boards and a dry, transparent, non-sticky, nongreasy, cushioning anti-squeak coating in said joints from top to bottom, and end to end thereof, said coating including a molecular mixture of one part .of paraflin to five parts of rubber.

6. In combination, a floor having adjacent faces of adjacent boards coated with a dry, cushioni-ng anti-squeak coating including a molecular mixture of parafiin and rubber said mixture being free of sticky substances and free of non-volatile oils which would grease the floor.

7. A method of silencing floor squeaks in a laid wooden flooring having cracks therein consisting of treating the squeaking portions thereof through the associate cracks thereof with a solution including paraflin dissolved in a fluid volatile solvent.

8. A method of silencing floor squeaks in a laid wooden flooring having cracks therein, consisting of treating the squeaking portions of said flooring through the cracks thereof with a squeak silencing fluid including rubber dissolved in a fluid volatile solvent.

9. A method of silencing floor squeaks in wooden flooring having tongue-and-groove connections forming cracks, said method comprising introducing into said cracks and allsqueaking portions thereof a fluid solution comprising a low viscosity volatile solvent containing a dissolved non-drying surface coating anti-squeak material,

said solution passing to said portions by capillarity because of said low-viscosity.

10. A method of silencing floor squeaks in a laid wooden flooring having tongue-and-groove cracks therein, said method consisting in introducing by capillarity to the squeaking portions of said cracks, a low-viscosity solution of lubricant and cushioning material dissolved in a low-viscosity fluid volatile solvent.

11. In combination, a floor having adjacent faces of adjacent boards coated with a non-greasy mixture of rubber and a lubricant.

12. In combination, a floor having adjacent faces of adjacent boards coated with a nongreasy, anti-squeak coating including an intimate mixture of parafiin and a cushioning material.

13. In combination, a floor having adjacent faces of adjacent boards coated with a mixture of parafiin and rubber.

14. A fluid for silencing squeaky portions of substance dissolved in a quickly volatile solvent, the proportions being such that the fluid is thin enough to be quickly drawn into a floor crack by capillary action, and the substances are concentrated enough to silence squeak after the solvent evaporates, said fluid being free of dirty, greasy and friction forming materials.

16. A fluid for silencing squeaky portions of wood floors, comprising non-volatile squeak silencing and cushioning substances dissolved in a quickly volatile solvent, said substances comprising about 40% of said fluid, whereby the fluid is thin enough to be quickly drawn into a floor parafiin are concentrated enough to silence squeak 10 after the solvent evaporates.
