CLINICAL THERMOMETER.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed May 25,' 1912. Serial No. 699,773.l

To all whom t may concern Be it known that I, WILLIAM MARION Bevis, a citizen of the United States, residing at Lakeland, in the county of Polk and State of Florida, have invented certain new and useful Improvementsin Clinical Thermometers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in clinical thermometers and more particularly to an antiseptic case therefor, and my object is to provide a case of this character adapted to contain antiseptic fluid which will removeall germs or the like from the thermo-meter, as the same is placedy therein.

A further'object of the invention resides in providing a case formed in sections, the one section of which is provided with means to prevent the antiseptic fluid from flowing therefrom.

A still further object of the invention resides in providing va device whichA is extremely simple and durable in construction, inexpensive to manufacture and one which will be very efhcient and useful in operation. With these and other objects in view, the

yinvention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim. y

In the accompanying drawing forming a part of this application, Figure l is a side elevation of the device. IF ig. 2 is a vertical section therethrough; and Fig. 3 is a horizontal section4 through the same, as seen on line 3-3, Fig. 2.

In describing my invention, I shall refer to t' e drawing in which similar reference characters designate corresponding parts throughout the several views and in Which- 1 indicates a cylindrical barrel or casing formed of the sections 2 and 3 which are threaded into engagement with one another as shown at 4. The bore of the section 2'of said barrel or casing isquite small and the bore of the section 3 at that portion thereof connecting with the section 2, is of a similar diameter, but .this restricted bore ofthe latter section 3 communicates with an e11- larged bore or cavity 5 which extends for the greater portion of the length of said section 3, the walls of the bore o r cavityv 5 tapering toward the restricted bore, as shown atI 6. The upper or outer end `of the section 3 is provided with a contracted opening or neck portion 6 which is threaded, and formed integral with this neck portion of the section is a tube or the like 7 which extends longitudinally intothe section 3 and terminates at a point a short distance above the point of communication between the enlarged bore portion thereof.

A cap or head member 8 is adapted to be applied to the upper or outer end of the sec- Ition 3, saidcap or head being provided with a threaded shank or the like 9 to be engaged with the threaded neck portion 6 and said cap member is provided with a central channel 10 to snugly receive therein one end of a clinical thermometer :'11. Thus when the cap member 8 with t 'e thermometer ll applied thereto is properly applied to the section 3, said thermometer will be disposed through the tube 7 and into the restricted lbores of the sections 2 and 3 and as the restricted bore ofthe section 2 is adapted to contain an antiseptic fluid, it will be understood that germs 'or the like on the thermometer will bereadily removed. That portion of the neck 6 of the section 3 connecting the tube 7 thereto is slightly tapered as shown at 12 and the end ofthe shank 9 is similarly tapered to fit snugly thereagainst when said cap is properly applied to the device and thus it will be practically impossible for the fluid within the device to leak therefrom, should said fluid find a passage-way through the tube 7. 1

o andthe restricted bore portionl In practice, the section 2 of the barrel or casing'is filled with an antiseptic fluid to a poi'nt immediately adjacent the neck or threaded portion thereof, whereupon the section 43 is properly applied thereto. The cap 8 with the thermometer yl1 pro mounted therein is then applied to the sec# tion 3 and as the thermometer 11 is inserted in the section 2, the fluid therein will, of course, rise to the level o-f the plane at which the tapered portion 6 of the -bore 5 communicates with the restricted bore portionof said section 3. Thus it will be seen that the perly 4 thermometer 11 will have the greater portion `thereof inserted in the antiseptic fluid when pro-perly disposed in the casing. When the cap 8 with the` thermometer 11 is removed from the casing for practical purposes, the operator may allow the casing to rest horizontally on a flat surface without danger of the iuid iiowing from the same for, as the device is placed on the surface, said fluid will flow into the cavity or enlarged bore 5 surrounding the tube 7.v As the space from the wall of the tube 7 to the wall of the section 3 proper, is considerably greater than the diameter of the restricted bore of the section 2, the fluid therein, when the device is in a-horizontal position on a fiat surface,

will never reach a point whereby it may iow through the tube 7 and thus the device may be completely inverted and the fluid therein will entirely surround the tube 7 but will not ow Itherefrom.

It is `perfectly natural for one using a clinical thermometer to place the case therefor flatly upon a table or the like, but considerable inconvenience has heretofore been experienced in the placing of such cases upon a table, since the same have not been provided with such means as to prevent the iiuid from iiowing therefrom. With a device such as I yhave provided however, no

tion may be resorted'to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention, what I claim is A case for clinical thermometers comprising a tubular casing closed at one end thereof and provided with a restricted bore extending the greater portion of the length of the same, said restricted bore being adapted to contain a liquid and terminating in an enlarged bore at the upper end of the casing, said enlarged bore having the Walls'at the lower ends thereof tapered toward said .restricted bore, the open end of said casing being threaded, a tubular extension disposed within said enlarged bore to a point above the junction of the enlarged and restricted hores, the upper end of said tubular extension being fiared outwardly and formed integral with the walls of the open end of said casing, and a cap having a shank thereon adapted to be disposed in the open end of said casing, said shank being threaded for a portion of its length to engage the threads of the casing and also tapered for a portion of its length to contact with the Haring upper end of said tubular extension.

In testimony whereof I hereunto aix my signature in the presence of two witnesses.

WILLIAM MARION BEVIS.
