PATENT CALIFORNIA, ASSIGNOR TO RECORDING WASHINGTON CONTAINER Application mea october 7, 192e. semi No. 398,021.
This invention relates to containers.
An object of the invention is to provide a container more particularly adapted to house a thermometer, including thermostatic elements responsive to changing temperature, and wherein the container or housing is made up of metal having high thermal conductivity so as to insure correspondence of temperatures within and without the container, and enable the thermostatic elements within the container to accurately register' external temperatures while being protected against moisture, corrosion, and the like.
Another object of the invention is to provide a container of the character referred to, having means for sealing the container against the entrance of moisture and locking the same against unauthorized tampering, said means including a closure which may be locked in various positions to insure a sealing lit.
Still another object of the invention is to provide a bracket for supporting the container, which bracket is incorporated in the locking means in such a way that the container and closure are locked to the bracket by the same means utilized for locking the closure in its sealing position.
Other and further objects of the invention will appear hereinafter.
In the drawings forming a part of this specification, Fig. 1 is a top plan view of the container and the supporting bracket therefor. Fig. 2 is a partial vertical sectional view through the container, the bracket, and the supporting wall therefor. Fig. 3 is an enlarged fragmentary front elevational view of the container, showing the latching mechanism associated therewith. And Fig. 4l is an enlarged vertical sectional view through the container' and the locking means utilized in connection therewith.
As shown in the drawings, the invention comprises a cylindrical body portion and detachable closure made up of metal having high thermal conductivity, to adapt the same for use in housing and protecting a recording thermometer, including thermostatic elements, a stylus and a recording mechanism,
all as shown in my pending application, Serial No. 15,745, tiled March 16, 1925.
As appears from the said pending application, the thermometer proper is intended to be placed in a refrigerator car to record temperatures during the travel of the car from place to place. This necessitates the use tion 10 is provided with a laterally projecting annular shoulder 13, having a plurality of radially disposed grooves or notches 14E which extend at intervals entirely around the annular shoulder 13. The inner surface of the mouth of the container 10 is threaded as indicated at 15, adapting it for the reception of a portion of the closure 11. The upper edge surface 16 of the container provides a seat for a gasket or sealing ring 17, preferably of rubber, fibre, or other compressible substance adapted to provide a sealing fit between the closure and the container. The closure 11y is disc-like in form with a projecting annular flange 18 exteriorly threaded to engage the threaded portion 15 of the mouth of the container. The closure is also provided with an Vannular shoulder 19 adapted to bear upon the sealing member. The flange 18 defines a cavity 2O in the under surface of the closure 11 adapted to receive absorptive l material 21 which aids in rendering the interior of the container free' of moisture. The closure 11 is further provided with an annular rib 22 at its upper end, said rib project-- ing an appreciable distance above the top 23 of the closure. The outer surface of the rib 22 is roughened or knurled, as indicated at 24 to facilitate rotation of the closure with respect to the container so as to engage and disengage the threaded connection therebetween. The rib 22 is provided with diametrically disposed, horizontally extended slots 25, best shown in Fig. 2, for the reception and accommodation of a bracket hereinafter described.
Secured to the outer circumferential surface of the shoulder 19 of the closure, is a support-ing strap 26, having a looped portion 27 adapted to accommodate a latch or dog 28, the latter being pivotally hung upon a pin 29 extending between the legs of the looped portion 27. The head 30 of the dog is adapted to be engaged with any one ot' the grooves or notches 14 in the annular shoulder 13 of the container body portion, being shown in engaged position in full lines in Fig. 4, and in disengaged position in dotted lines in said ligure. The supporting strap 27 is secured in such a position as to lie under one of the slots 25 in the rib 22 as best shown in Fig. 3, and the tail 31 of the dog in its inoperative position moving across the plane defined by the slot 25.
Adapted to extend through the slots 25 of the closure 11 is the supporting bracket 32, said bracket having an anchored portion 33 permanently secured to the wall 34 by suitable means such as a screw 35. Extending substantially at right angles to the anchored portion 33 is an elongated section 36, ot such size as to be admitted first through the slot 25 opposite to the dog 28, and thence through the slot 25 adjacent to the dog, the end portion 37 of this section, when extended through the latter slot, bearing upon the tail 31 of the dog 28, and rotating the same in a counter clockwise direction to bring about engagement ot the head 30 of the dog with one of the notches 14 and to maintain said dog in such engagement. The extreme end 3S of the bracket is provided with an aperture 39 for the reception of the strap of the seal 4() ot a type commonly used in connection with railroad equipment.
In operation, assuming the container to be in position to house the thermometer as illustrated in Fig. 2, and it is desired to withdraw the thermometer at the end ot the journey, the seal 4() may be broken. After this is done the entire container, including the closure, can be withdrawn from engagement with the bracket merely by retracting the bracket from the slots 25 in the rib ot' the closure. IVithdrawal of the supporting portion ofthe bracket releases the tail of the dog, after which the dog may be retracted from its position within one of the notches 14, and the closure may then be unscrewed or unthreaded from the container body proper, permitting the thermometer to b-e removed from the container.
At the start of a journey a thermometer is irst placed in the body portion ot the container, after which the closure member, with the sealing ring 17 disposed about the annular flange 18, is applied to the container and screwed home. Due to the tact that the rotation of the closure with respect to the sealing ring, may bring the locking dog to ditlerent positions at different times, provision is made for this contingency by providing the plurality ot notches or grooves, one of which will be adjacent to dog, no matter in what position it comes to rest after the closure is screwed tightly enough in position to afford a sealing lit. rIhe container and thermometer are then adapte-d to be mounted upon the supporting bracket and the end of the latter is first inserted through the aperture remote from the dog, and then extended to the aperture above the dog, during` this operation securing the tail ot the locking dog against reverse rotation, and securely locking the closure in position against unauthorized tampering. The seal 40 is then applied to the outer end ot the bracket, thereby securing the thern'iometer and container to said bracket in such a way that unauthorized tampering with the thermometer may be readily detected.
Although the invention has been described with particularity, it is not the intention to limit the same to the precise details shown, since variations in construction may be made without departing from the principle of the invention.
