' UNEEE STATES PATENT OFFICE 2 Claims.
This invention relates to devices for applying a liquid wax or other similar substance to a fioor or other flat surface, and has for its objects to provide a device which carries its supply of liquid wax to be applied to the fioor within its structure; which prevents the entrance of air therein, thereby preserving the wax in a liquid state; in which the rate of fiow of the liquid from the container may be easily and accurately controlled; in which the control valve is closely adjacent the applying device, thereby preventing the wax from contacting the air; which may be easily disassembled for the purpose of cleaning the parts covered with wax which might be hardened by contact with the air; and which is simple and cheap to manufacture, easy to use, and which effectively applies and spreads the wax in an even and efficient manner.
I attain these and other objects by the devices and arrangements illustrated in the accompanying drawing, in which Fig. 1 is a side elevation of my improved floor waxing apparatus; Fig. 2 is a vertical section of the upper part thereof; Fig. 3 is a similar view of the lower part thereof; Fig. 4 is an elevation of a part of one of the retaining bars; and Fig. 5 is a plan view of the applying pad.
Similar numerals of reference refer to similar parts throughout the several views.
Referring to the drawing, it will be seen that the main part of my improved floor waxing apparatus comprises a tube I, which may be about one-and-a-half inches in diameter and about three feet long. The upper end of this tube I is provided with a suitable plug 2 permanently secured therein by brazing, or other suitable means, which is provided with a suitable stuffing box 3, through which the control rod 4 passes. Also an inner tube 5, which may be about A; inch in diameter, is similarly secured to the plug 2, in coaxial position within the main tube I. An operating handle 6 may be attached to the upper end of the tube I and is provided with a hole I in which the upper end of the control rod. 4 is mounted. An adjusting handle 8 is mounted on the rod 5, and is secured thereto by means of the set screw 9, at a point above the stuffing box 3.
A partition Iii extends across the inside of the tube I, near its lower end (Fig. 3) and said inner tube 5 is similarly secured to its upper surface. This partition I0 is provided with a central hole II through which the control rod 4 passes, and with one or more holes I2 (only one of which is shown) near its outer edge for the hereinafter described purpose.
A second short inner tube I3, which may be considerably larger in diameter than the said tube 5, is coaxially secured to the under side of the said partition Ill and extends therefrom to a second partition I4 and is provided with holes I5 at its lower end. The inner surface of this tube I3 is screw-threaded for a considerable length, and a screw-threaded plug or valve I6 is mounted therein, said valve being secured to the end of the control rod 4. That portion I I of the lower partition I4 lying under the said plug valve It may be dished to conform with the lower surface of the said valve I6 to form the valve seat therefor. An outlet tube I8 extends concentrically down from the valve seat H. The valve I6 therefore controls the outlet tube I8. A union nut I9 is mounted on the end of the outlet tube I8 to secure the applying pad or foot to the tube I. A filling orifice 20 is secured near the upper end of the tube I, said orifice being suitably closed by a lid H, or otherwise.
The applying pad comprises a block of wood 22 of suitable size and shape, in which a crosstube 23 is secured, said tube 23 lying in an opening in the bottom of the block 22 and being provided with a short tube 24 extending centrally from the block 22 and screw-threaded at its end to connect with the union nut I9. A pad 25 of sheep skin is clamped on to the block 22 by means of a pair of clamping bars 26 having ears or lugs 21 extending upward therefrom (Figs. 3 and 4), through which a pair of clamping bolts 28 pass, said bolts lying in holes in the upper part of the block 22 and being provided with thumbnuts 29. The block 22 may preferably be grooved along its upper front and rear edges to allow the edges of the sheep skin 25 to be pressed therein by the clamp bars 26. The cross-tube 23 is closed at its ends but is provided with a series of outlet holes 30 along its underside. The sheep skin 25 is also provided with a plurality of holes 3| therein, said holes 3| being arranged so as not to coincide with the holes 30 in the tube 23, as indicated in Fig. 5.
My improved floor waxing apparatus is operated in the following manner: The valve I6 being screwed down onto its valve seat I! by means of the rod 4, the closure lid 2| is opened and a charge of liquid wax is poured into the receiving orifice 20-. This liquid wax fills the annular space between the tubes I and 5 and flows through the holes I2 in the partition I0 to fill the annular space between the tubes l and i3 and then flows through the holes l5 to surround the end of the plug valve l6. As soon as the valve [6 is opened by the manipulation of the control rod 4 the liquid wax flows through the outlet tube l8 and into the short central tube 24 to the cross tube 23, which it fills, flowing tout therefrom by the small holes 30 to fill the space in which the tube 23 lies and to flow out therefrom by the holes 3! in the sheepskin 25 and thus be spread by the movement of the apparatus on the floor.
The applying pad or foot may be removed from the apparatus by disconnecting the nut H! from the tube 24 and by looseningwthe thumb nuts 29 on the bolts 28 to remove the sheep skin 25 from the block 22, thus permitting all the parts in which the waxv is likely toibe exposed to air to be easily cleaned.
It is, of course, understood that many variations in the details of any apparatus may be made without departing irorn:thev spirit of my inventionas outlined in the appended claims, for
instance changesamay be made in the form of the valve or in its means of operation. or it;may bebrought .down closer to the applying pad, or the'pad maybe made of felt, cloth, "or other suitable substance. v
'Having, therefore, described my invention, what I claimand desire to'secure by Letters Patent is:
1. A floor waxing apparatus, comprisinga main outer tube; an inner tube coaxially secured therein; an upper plug for the outer tube; a stufling box for the upper end of the inner tube; a partition near the lower end of said outer tube, to which said inner tube extends; an opening in said partition between said inner and outer tubes; a second partition substantially at the lower end of said outer tube; a screw-threaded tube coaxially mounted in said outer tube between said first and second partitions; an opening in'the side of said screw-threaded tube, the
space between said outer tube and said inner tubes forming a compartment adapted to receive liquid wax; a delivery pipe secured to said second partition and communicating with the interior' of said screw-threaded tube; a screw- Vthreaded valve engaging the threads in said tube, and controlling the entrance to said delivery Lpipe; .a control rod secured to said valve and passing coaxially upward through said inner tube and. stuffing box, whereby said valve may be :turned; andvmeans'removably secured to-s'aid delivery;- pipe and adaptedto receive the zliquid :waxtherefrom'and to spread it on the floor.
2nArfloor waxing apparatus, comprising a block; a groove in the under side of. said-block; .a cross-pipe mounted in said groove and having outlet-holes in its lower wall; a central "pipe communicating'with-said cross pipe andladapted to be removably attached toa liquid-wax-delivery :pipe;.an applying pad onthe under side'of; said block; and means for releasablyclampingsaid pad to said block.
