FRANKLIN HARDINGE, F CHICAGO, ILLINOIS.

RECEPTACLE.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application led October 23, 1907. Serial No. 398,817.

To all whom it may concern:

-ing will usually occur.

Be it known that I, FRANKLIN HARDINGE, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and useful Improvement in Receptacles, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to receptacles, particularly to receptacles intended for containing volatile oils, its object being to provide an improved form of portable receptacle which is non-spillable and self-closing.

In various trades volatile oils are constantly in use, as, for example, in machine shops, where machine parts or tools are to be cleaned of oil and grease. Where open receptacles are used, or those having detach' able covers, there is great danger of fire, as upon tipping or droppino' of the receptacle the oil will flow therefrom and rapidly spread, and if it should become ignited the flame would travel with great rapidity to surrounding combustible objects and the fire would almost instantly become uncontrollable.' Even where a detachable cover is provided for a receptacle, the receptacle is open during the time that it is in use, and itis during this time that tipping or spillthe receptacleabout, even with the cover on, the cover would become detached should the receptacle be dropped.

In general, my invention `provides for cover or closing means which is always attached tothe receptacle and which forms partthereof. The closing means is automatic in its operation and allows ready access to the oil within the receptacle but which instantly automatically closes the receptacle after use thereof.

The details of my invention will be better understood when described by reference to the accompanying drawings, in which- Figure 1 is a side elevation of a receptacle embodying my invention; Fig. 2' is a rear elevation thereof; Fig. 3 is a plan view with the outer cover removed, and Fig. 4 is a sectional view of the entire device taken on a plane passing through line 4-4 in Fig. 3.

I have shown a receptacle 1 in the form of a rectangular box which may be formed integral of sheet material. The front wall 1 along its upper edge has the indentation Also, in carrying 2 forming the projection 3 at the outside. The

side walls

4 and 5 at their upper edge are indented to form the inner shelves or ridges 6 and 7. Arranged just within the upper edge of the box is the frame 8 having an L-shaped cross-section, as shown, and.

which frame may also be formed integral from sheet material. The front wall 9 of this frame is indented from the inside to form a bead 10 for engaging in the indentation 2 in the front Wall of the box, while the

side walls

11 and 12 of the frame 8 rest on the ledges 6 and 7 in the side walls of the box. 'lhe rear wall 13 of the frame is also indented outwardly to form the ledge or lug 14. The front end of the frame 8 is locked to the box by the engagement of the bead l0 with the indentation 2, and to lock the rear end of the frame to the box I provide a locking frame l5 of sheet material whose upper part 16 is hooked to engage over the top edge of the rear wall 17 of the box, the end 18 of the hook engaging the lug 14 of the frame 8.

The frame 15 has the V-shaped locking ridge 19 along its lower edge and is engaged by the locking hook 20 extending along the edge of the sheet metal spring frame 21 secured to the rear wall of the box by means of rivets 22. The frame 8 is thus locked against the side ledges 6 and 7 The entrance opening 23 rovided by the frame 8 is normally closed y the trap door or lid 24 disposed within the box below the frame 8 and held against the frame 8 b means of a coiled spring 25. The trap 1i is of sheet material and 1s rectangular, its dimensions being Slightly less than those of the box to leave a small clearance space 26. The edgesof the lid are, however, cut away the greater part of their length, leaving the guide lugs 27 at the corners, the body part of the lid, however, being larger than the entrance opening 23. The shape of this lid is best shown in Fig. 3. .The middle portion of the trap lid is intended to provide a dome or pocket 28 for receivin(1V the upper end 29 of the coiled spring, the spring being secured at this end' to the lid. The trap lid by pressure thereon can readily be moved downwardly and to the bottom of the box, the spring being of the bed spring kind t0 contain itself when collapsed. The lugs 27 at the corners of the trap lid guide the lid in its vertical of the trap lid is, as before stated, to form by-passageways for oils upon downward movement of the lid and also to allow the l1 d t0 clear the ledges 6 and 7. rl`hus, 1f 1t is desired to clean a tool or a piece of work, the workman pushes down the trap lid Vbelow the surface of the oil and uses the oil-in any way desired. Upon withdrawing of the hand or work the lid immediately falls and is pressed against the frame 8 to seal the opening 23. r1`hus the receptacle'is always automatically kept in closed condition. As the trap lid is carried upwardly some of the oil may be carried therewith, but to drain this oil back into the receptacle I provide small drain openings 30 through the trap lid which I cover with gauze 31, as shown. Any oil which may be carried out with the `trap lid will flow back into the receptacle through these drain openings. tf the box should come into contact with a flame, this flame could not reach the oil through the drain openings on account of the gauze and the worst that could happen would be the burning of the oil vapor over the drain openings. 1f the receptacle is tipped the gauze will allow very little of the oil to escape, and at any rate, the receptacle would be picked up and righted before suiicient oil could escape through the gauze meshes to cause any harm. lf it were not for this automatic self-closing lid, tipping of the receptacle would allow escape of the entire contents or a sutiicient amount thereof before the receptacle could be righted, and the oil would rapidly spread over surrounding com* bustible objects and, therefore, if ignited would spread the llames very rapidly. An outer lid 31, might also be provided which would assist in preventing spilling of the oil and which would also be effective in choking out any flames which might reach oil within the frame 8 or on the trap lid. This cover 31 is so attached that its center of gravitywill tend to move it toward the closed position. |The cover is rectangular ,and slightly larger than the receptacle outlet and has at its front edge the lug 32. At its rear end is secured the hinge frame 33 having hinge lugs 34 at its ends. These hinge lugs are hinged, as by means of rivets 35, to companion hinge lugs 36 which may vform part of the locking frame 15, as shown. The outer corners of the hinge lugs 34 form stops 37 which engage the locking frame 15 and prevent opening of the cover beyond Ia pointl at which its center of gravity would tend to return it to its closed position. When the oil in the receptacle is to be used the workman must lirst open the cover and then press down the trap lid. l/Vhen he withdraws from the receptacle the trap lid is snapped upwardly by the spring to automatically close the entrance opening 23 and the cover 31 automatically drops shut. The

eaasaa top edges of the frame 3 are preferably brought in a plane with the edges of the receptacle to be engaged by the cover when closed.

A rllhe receptacle can readily be filled or ysome of its contents' removed by holding down the trap lid. rlhe receptacle can also be readily cleaned by removing the cover,

the trap frame and lid, and the spring, by

pulling out the spring frame 21 toy remove its pressure from the lock 19, and by pulling upwardly at the rear end of the cover, the cover with the locking frame 15 can be re- \moved and thus the end 18 of the hook 16 removed from the path of the ledge or lug 14 on the frame 8, and by lifting the rear end of this frame upward its front end can receptaclevto prevent it from wedging itself' in an upright position between the frame and bottom. lVhere adeeper receptacle is used the downward travel of the lid should be limited so that its proper closure is insured.

A very simple but eflicient portable, selfclosing receptacle is thus formed, of which allthe parts except the spring can be made from sheet material by means of dies. not wish to be restricted to the eXact form or shape of the receptacle, nor to the exact form or/shape of the various parts thereof.
