FLOOR OILEB.

Application filed February 24, 1922. Serial No. 539,049.

To all whomz't may concern:

Be it known that 1, CHARLES W. Comer, a citizen of the United States, residing at VVatertown, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Floor Oilers, of which the following is a specification.

This invention relates to devices for spraying oil upon floors, and its object is the eiiecting of the improvements hereinafter set forth.

In the drawings forming pa1t of this specification, Fig. 1 is a central sectional elevation of an oiler embodying my improvements, parts being broken away for shortening the view. Fig. 2 is a detail view 01" a portion of the spray-controlling means. Fig. 3 is a side view of the lower section of the pump cylinder. Fig. 4 is a plan view of a device for guiding the lower end of the pump cylinder into its seat. Fig. 5 is a perspective view of the foraminous shield for keeping particles in the oil from reaching and obstructing the action of the pump valve. Fig. 6 is a perspective detail view.

The oil container consists of an elongated sheet metal cylinder 1 having top 2 and bottom 3, which is filled through a plugclosed opening at 4. The pump cylinder 5 is made longer than the oil container 1 in order to reach the bottom 3 and rise a short distance above the tOp 2, and is threaded at its lower end, as at 6 in Fig. 3, in order to screw into a socket 7 held by the bottom 3. Near the upper end of the cylinder 5 is a threaded sleeve 8 soldered or otherwise tightly attached thereto, and having a shoulder 9. This sleeve screws into an internally threaded collar 10 held by the top 2, a washer 11 being introduced between the shoulder and collar in order to render same air-tight.

The piston 12 is of well known form, having its rod 13 provided at its outer end with an operating handle 14, preferably spherical in shape.

Spaced from the lower end of the cylinder 5 is a disk 15, soldered or otherwise fastened in place, and provided with a port 16 closed by a leather flap 17 for preventing the entrance of oil to the cylinder. Through the cylinder wall beneath the disk 15 are three or four openings 19 for passage of air from the pump and the entrance of oil from the container, these openings being shielded by a screen 20 for preventing any impurities from the oil reaching the port 16 and, by getting between the latter and the leather flap 17, preventing the tight closure of the port as the piston is being drawn upward.

I prefer to form the shield 20 from a length of foraminous material, as shown in Fig. 5, of proper height to fit between the disk 15 and the lower extremity of the cylinder 5, the elastic pressure of the bent material serving to retain it in position when the pump is removed, while at the same time permitting its easy withdrawal for cleansing purposes.

Attached to the socket in any suitable way, as by solder, is a ring 21 from which rise three or more fingers 22, as shown in Figs. 1 and 4, the object of which is to guide the lower end of the cylinder down into the socket 7 when the same is returned to the container.

The spraying cock 23 is of well known construction, communicating with the space within the lower extremity of the cylinder 5, and opened by means of a finger 24 connected by a metal ribbon or link 25 to a finger piece 26 positioned at a point conveniently reached by the finger of the operators hand which is grasping the handle 27. This finger piece 26 is slidably carried in an elongated shield 29 whose lower end is attached to the container, and whose upper end is attached to the handle 27, and is retained therein by a cross piece 30. The finger piece is preferably formed by doubling over on itself a length of ribbon metal, one leg 31 of which is engaged by the link 25, and the other leg of which is bent up to compose a foot 32 which by its contact with the cross piece 30 holds the finger piece from further descent as urged by the spring 33 with which the cock and finger 24 are provided.

As shown in Fig. 6, the end of the leg 31 is formed with a link-engaging eye 34 having a leaf 35 behind it whose edge contacts with the shield 29, whereby the end of the ribbon can be thrust up behind the leg 31 and will be guided by the leaf 35 out through the eye 34, after which it can be bent down to hold it in place.

the oil container is prolongedafar enough below the cook and connected'parts to per mit the oiler to be stood upon a flat surface to hold itself upright, and t0 ensure the cock and connected parts against injury.

In using this oiler, the container 1 is first nearly filled with the oil, and then the piston is reciprocated until a suitable air pressure is secured Within the container to properly expel the oil in a fine spray through the spraying cook. The operator tllengrasps the-handleQ'T, with his thumbresting against the-shouldeii36 and his: torefinger-beneaththe finger piece 26 and by pulling upon the latter opens; the cook 23 and begins the spraying operat on, the contain'er being sW ung from side to side as he; Walks; along the floor; morder that a Wide section of the latter can be treated as he advances.

By having the port 16 and its flap 17 close to the bottom 3 and beneath the opening 19 there will remain a sufiicienl: amount of oil, even in case the container is nearly empty; and there is considerable air pressure withiinrender the flap absolutely air tight in its closure of the port 16. In all other oilers, so far am aware, there is no such retention of oil about the flap, and consequently there will be a steady leakageof air from the container. and a forcing up of the piston rod to its full height.
