DEVICE FOR REGULATING HUMIDITY or oontmmnns.
Application filed December 18, 1922. Serial No. 607,731.
cago, in the county of Cook and State of Illinois, haveinvented a. certain new and useful Improvement in Devices for Regu-' lating Humidity of Containers, of which the following is a specification.
My invention relates tomeans for controllingthe moisture content in the air within a glass jar or similar container. The invention is of Special utility in connection with the use of hollow stoppered candy jars the purpose being tokeep the air within the jar as dry aspossible to prevent the'candy from becoming sticky. Generally speaking I provide a receptacle for containing a dehydrating substance and equip it with fastening means composed of arms which are comparatively stiii and, means for causingsaid arms to positively engage the stopper, thus locking the restopper of a jar.
ceptacle to the stopper. I obtain my object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is an assembly view showing any device in position within the cap or The view is taken in axial vertical sectiong Figure 2 is a plan section on the line Figure 3 is a sectional elevation on the line Figure 1.

Figure l. is similarto Figure 1 but shows amodilied type of means for retaining the dehydrating material in position within the stopper. r
Figure 5 is a plan section on the line Figure 6 is a plan view of the cover showing the arms removed. Figure 7 is a perspective view of the typeof retaining arm employed in the form shown in Figures 4: and 5. 1
Like numerals denote like parts throughout the several views.
Referring first to the type shown in F igure 1,.the jar 1 has astopper 2 having a flange Swhich fits into the mouth of the jar. The stopper is internally chambered and has an internal annular I shoulder 5 'ioraminous bottom 7 and a cover 8.
which faces upward and inward and an annular shoulder I which faces downward and inward.
The dehydrating material (not shown) is designed to be held within a receptacle which, according to the illustrated form, consists of a cylindrical box 6 having a In the illustrated design the cover is circular in outline andhas'a marginal flange which fits over the uppergedge of the boX. The
design of the receptacle may, however, be
considerably altered without departing from the spirit of the invention.
The cover 8 has upstanding cars 10 which arepreferably struck out of the metal of the cover itself. They are arranged in pairs and apertured in alignment with each other to support pins 12 which are arranged horizontally and form pivots for the lower end of retaining arms 14. These arms are approximately V shaped and may be made of strap metal as stiff and heavy as desired. The parts are so proportioned and arranged that the bends of these retaining arms close- 1y approach each other above the center of the cover. Their outer ends extend radial ly outward far enough that when the bends are sufiiciently elevated above thecover the outer upper ends of the arms will'en'gage theishoulder 5 of thestopper and hold the cover in close contactwith the shoulder 4. It will be observed that the arms are approximately V-shaped, the outer end of one arm being connected to the receptacle,and
the outerend of the otherarm resting upon the internal shoulder of the stopper. The arms are rotated about their pivots to engage'and disengage the shoulder 3 by a screw 16, the upper end of which works in a nut 17 held centrally in the cover 8. In the illustrated form the nut is rigidly held onthe top of the cover by lugs 18. which are formed from the metal of the cover itself. The screw extends down through thebottom of the box 6 and at the lower end haswings 19 or other means by which it may be readily grasped and rotated by the user. The upper end of the screw underlies the bends of the arms 14 and the parts are so designed and proportioned that when the screw is backed off, so that its upper end is flush with the upper surface of the nut, the arms let will fall downward as shown in full lines in Figure 1 in which position they disengage the shoulder 5 and are free to pass out through the neck of the stopper. By rotating the screw to move it forward and upward the arms will be rotated about their pivots in a direction to move the upper outer end outward so as to overlie the shoulder 3 as illustrated in dotted lines in Figure 1. This holds the cover suspended within the stopper. The box 6 will be supported either by -frictional engagement with the flange of the cover or by resting upon the wings 19.
In operation, when it is desired to remove the box and contents from the stopper the screw 16 is first backed off sufliciently to permit the arms 14: to swing inward and disengage the shoulder 3 of the stopper. My entire device may be thereupon lowered away and removed from the stopper. The screw may then be backed off further so as to entirely release the nut 17. This will permit the cover 8 to be lifted off and the dehydrating material within to be removed and renewed. After fresh dehydrating material has been introduced the cover may be replaced and the reverse operation performed. If desired a pin 20 may be passed through the screw within boxG to prevent the screw from being entirely removed from the box when the box and cover are separated.
The form of device shown in Figures l, 5 and 6 is. similar in general principle to the form hereinabove described, the chief diiference being in the details by which the arms are articulately connected to the cover. In this form the arms have notches 26 at the side near the lower end and these are designed to engage the sides of slots 28 formed in the cover. Near the inner end, at the points 29, the metal at the sides of the slots is rounded upward so as to form a seat for the projecting lugs 30 formed on the arms 25 below the notches 26. The arms are assembled with the cover by first inserting the lugs 30 lengthwise of the slot and then turning them crosswise so that the lugs will seat in the uppressed seats 29. When the parts have been thus assembled there results an articulate connection between the arms and the cover and the general etl'ect and principle of operation are the same as before.
From the foregoing it will be evident that my device may be regarded as having a receptacle provided with arms which are hinged to the cover in such manner that they can swing into and out of the chambered portion of a chambered stopper thus enabling them to engage and disengage the converging portion of the internal surface of the stopper at the lower portion of the chamber so as to support the receptacle within the stopper or to release it as the case may be. These arms are controlled by screw mechanism operable from a point beneath the receptacle. In view of the degree of control, which the operator has over the position of the arms, a considerable range of variation in the dimensions of the stopper may be compensated for. The arms may be rigid or may be resilient in accordance with the wish of the designer, but I prefer to malre them comparatively still or rigid for by so doing the receptacle when secured in place becomes locked there, and there is no danger of the receptacle accidentally dropping out when the stopper is handled.
Vhile the form of the receptacle and cover may be varied, a suitable design is illustrated, in which the cover is flanged sufiiciently to fit over the top of the receptacle and hold the latter and its contents by friction. This makes it possible for the receptacle to be charged and the cover forced down into place preparatory to inserting it in the stopper. This enables the receptacle and its cover to be manipulated as a single unit while being applied to the stopper,
l'laving thus described my invention what 1'. claim as new and desire to secure by Letters Patent is:
