Appiimion and January 19,1906. serial No. 296.878.

Be it known that I, WILLIAMl HENRY ISMITH, a subject ofthe King of'England, rer siding at Purley, in the county of Surrey, England, have invented certain new and use-l ful Improvements in Receptacles, of which, thefollowing is a speciiication.

This invention relates to improvements ini air-tight boxes, jars, or other receptacles--` such, for example, as the metal boxes used for storing sensitized photographic paper. I

One feature of this. invention consists in providing a simple and eiificient device for.l tightly closing the receptacle or for producing an air-tight joint round the edges of thert lid or cover, and in a specific form of air-tightt box embodying this invention and contain-v ing a desiccator a novel arrangement of the. box is provided. y r

The closing device I have` hitherto ein-f ployed comprises a lid having a packing-ring vat its edge and radially-movable segments arranged within the ring and connected by; toggle-arms with a central movable memberl by which the packing-ring may be pressed into close contact with the receptacle.

According to this invention the togglearms and separate segments are dispensed.,

, -1 with, anda dished frame, hav'ing resilient radial arms engaging the packing-ring at their ends, is arranged to be pressed downward in the center, so as to force the ends ofthe arms.

outward. The frame may be of sheet metal cut or slotted so as to form the radial arms, and the arms preferably terminate in seg-l mental pieces which are practically in contact vwith one another, so as vto produce an` even pressure all round the packing-ring. When the pressure is removed from the center of the frame,- the resilient Aarms cause the frame to recover its original form, thus with-k drawing the segmental pieces and releasing the closing device.

` l In one method according to this inven-` tion for pressing down the center of the.y frame a rod fixed at its lower end to the base,

of the lid projects upward through the center of the frame, and a handle pivoted thereto.` carries a cam arranged to force down the cen-,

ter of the frame when the handle is rotated. Preferably the cam has a lat end, so that when the handle is turned, say, in a horizontal position the center of the frame is forced down and retained in that position.

In arranging an air-tight box containing a desiccator according to this invention a hygroscopicagent is placed in a fiat pan or tray fitting easily into the bottom of thebox, and the .pan is covered with a perforated plate. To hold these parts in place andvto prevent paper from sliding down between the perforated plate and the side of. the box, a cylindrical'liner is inserted .in the box, so as to rest on the perforated plate. The top of this liner reaches nearly to the upper edge of the box and serves as an abutment on which the lid or cover may rest.

In the accompanying drawings, Figure l is a vertical section of a cylindrical receptacle provided with a closing devicel embodying this invention and particularly adapted for containing photographic paper. Fig. 2 is a similar view showing the closing device in its gripping position. Fig. 3 is a `plan showing the dished frame. Fig. 4 is a vertical section illustrating the novel internal arrangement of a box containing a desiccator. Fig. 5 is an elevation showing a modified form of lid, and Fig. 6 illustrates in plan the application of this invention to a rectangular receptacle.

Like letters indicate like parts in all the igures ofthe drawings.

Referring to Figs. 1, 2and 3, the receptacle itself A has an inner abutment or ange A near thetop to receive the lid. `The lid comprises a disk B, say ofsheet-zinc, turned upward at its edges. vWithin this and above it is a second disk B and between the disks is retained a packing-ring C, of india-rubber or the like, conveniently L-shaped in cross-section. This lid may be an easy iit in the top of the receptacle A. The lid has a rod D projecting upwardly from its center, the connection D between the rod D and the disk B being air-tight. and within the packing-.ring is a dished frame E, of resilient material, such as brass. This Ais in the form ofa fiat cone with its base rest- @number of narrow arms, which are extended at their ends to form segmental .pieces'E2 of such a size that there is a practically continuous series of segments within the packing,-

'ring C. Pivoted to the top of the central rod D is a handle G, at the bottom of which ar( lugs G', which form a substantially oblong,

Resting on the top of the lid 9 5 IOC ,from the disk BC In the form shown in Fig. 1 the desiccator is arranged in a known manner in the box A. The hygroscopic agent J, such as calcium chlorid, is placed in a flat pan K, and the pan is covered by a perforated plate K, screwed to the pan. The edges of the plate K rest on a {iange A2 near the bottom of the box.

Referring to Fig. 4, which illustrates a novel arrangement, the pan K fits loosely in the box A and is covered with a perforated plate K. The cylindrical liner L rests on the plate, and the top of the liner reaches nearly to the edge of the box, thus serving as an abutment on which the disk B may rest. 's Referring to Fig. 5, a flange or abutment inside the box may be dispensed with, and the cover H may be extended to form a flange H which engages the top of the box A.

This invention is applicable to receptacles of various shapes, and Fig. 6 shows the form of frame E which may be used for a rectangular box. The arms of the frame E in this case terminate in straight branches E3 and in corner-pieces E4, both engaging the packingring C.

It is -to be understood that the details of construction and arrangement may be varied without departing from this invention.

I/Vhat I claim as my invention, and desire to secure by Letters Patent, isi 1. The combination of a receptacle having an open mouth, a lid therefor, an expansible bar-.d around the lid, a dished frame on the lid having resilient radial arms engaging the expansible band at their ends, a central rod fixed to the lid and projecting through the vframe and a handle pivoted to the rod and carrying a cam arranged to force down the center of the frame when the handle is turned.

2. The combination of a receptacle having an open mouth, a lid therefor, an expansible band around the lid, a dished frame on the lid having resilient radial arms engaging the expansible band at their ends, a central rod fixed to the lid and projecting through the frame, a handle pivoted'to the rod and carrylng a cam having a iiat'end so that the center of the frame may be forced down and retained when the handle is turned.

3. The combination of a receptacle having an open mouth, a lid therefor, an expansible band around the lid, a dished frame on the lid having resilient radial arms terminating in segmental pieces engaging the expansible band, a central rod fixed to the lid and projecting through the frame and a handle pivoted to the rod and carrying a cam arranged to force down the center of the frame whel the handle is turned.

4. The combination of a cylinder closed at the bottom and open at the top, a metal lid therefor, an india-rubber packing-ring pro-- j ecting up from the periphery of the lid and secured thereto, a dished frame of resilient metal having a plurality of arms engaging the packing-ring at their ends, a rod projecting from the disks through the apex of the frame and a handle pivoted to the rod and carrying a cam engaging the 'top of the frame whereby when the handle is turned the center of the frame is forced down and presses the packing-ring into contact with the receptacle.

5. The combination of a cylinder closed at the bottom and open at the top and a lid comprising a metal disk turned up at its edges, a second metal disk above and within the first and secured thereto, an india-rubber packing-ring projecting :from the periphery of the disks and held between lthem, a'dished frame of resilient metal having a plurality of arms extended at their ends to form a continuous series of segmental pieces engaging the inside of the packing-ring, a `cover secured `on the lid over the frame, a rod projecting from the disks through the apex of the frame and the cover, a handle pivoted to the rod and carrying a cam having a at. end and engaging the top of the frame, whereby when the handle is turned vthe center of the frame is forced and held down pressing the packing-ring into contact with thefreceptacle.

6, In an air-tight receptacle the combination with a cylinder closed at the bottom and open at the top, a desiccator resting on the bottom, a cylindrical lining within the cylinder and resting on the desiccatonan impervious lid resting on the lining at the top of the cylinder, an expansible band round the lid, a dished frame on the'lid having resilient radial arms engaging the expansible band at their ends and means for pressing down `the center of the frame to move the ends ofthe arms outward and force the expansible band into contact with the cylinder.
