Description

Patented Mar. 6, 1923.
LOGA EISELE, F NEW YORK, N'. Y.
THERMOMETER. l
Application filed June 1, 1921. Serial No. 74,090.
To aZZ whom t may concern:
Be it known that I, LOGAN EISELE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Tmproved Thermometer, of which the following is a full, clear, and exact description.
This invention relates to thermometers particularly to medical thermometers. Prior to this invention, in the manufacture of thermometers which are enclosed in cas4 ings, the usual practice was to fasten the graduated tube into the cap by setting it 1n wax or cement. The consequence of such construction was that the graduated tube and cap were not always set in alignment and in many cases were broken when the cap was fitted on the casing. The graduated tube often worked loose during use and dropped out of the cap and if it was not broken caused the user a certain amount of inconvenience.
The object of this invention is to provide a thermometer which is constructed integral with' the casing cap and in proper alignment therewith so that when the cap is inserted in the casing there is no danger of breaking the thermometer. v
This object is accomplished by making the graduated tube with a bulb, cylinder, frustum o'r some other shape of stopper integral therewith and shaped to t the upper end of the casing, and providing, in- 36 tegral with the stopper, a finger grip.
This and' other objects of the invention will be more clearly understood from the following detailed description and accompanying drawings.
Figure 1 is a side View of the thermometer with part of the casing broken away to disclose the graduated tube and stopper; and
Figure 2 shows another form of stopper that may be used.
Referring to the above mentioned figures, a graduated tube 10 has a capillary bore 11 and a container 19 integral with the lower end. Mercury or some other liquid such as alcohol is contained in the container 19 and 5D is shown at 12 forced up the capillary bore 11 as the volume of liquid is expanded by increase in temperature. A stopper 14 is formed integral with the graduated tube and maybe of any shape suitable to close y the upper end of the casing. A preferred form, shown in Figure 1, is the shape of a cylinder. The lower edge of this cylinder might be rounded so that it wouldl present less diiiculty to insert it in the casing. This cylinder 14: is glass and may have an external thread thereon, in which case an internal thread would be supplied on the casing. In Figure 1, the cylinder vltisl shown withoutan external threadl and in such a `case the glass may be ground so that it will grip a smooth casing. Mounted on the cyl-k inder 14: is a finger grip 15 roughened so as to vpresent a good gripping surface. Fixed to the bottom of the casing is a ring 16 to which is connectedv a chain 17. .Fastcned to the free end of the chain is a pin which serves for fastening the thermometer to the clothing when it is being carried` around. y
Tn Figure 2 a stopper of a different shape is shown.
.In this ca'se`the stopper 20`isl the shape of a bulb and is integral with the graduated tube' 21 and'has a inger grip 22V connected thereto by means of a short neck 28. A. varietyyof differently shaped stoppers cast integral with the graduated tube might be used. l
laims:
1. As a new article` of manufacture, a
thermometer of the class described, comprising a graduated tube, a container for said graduated tube, a stopper of sphe'ricalv shape attached to the graduated tube for seating in the casing, said spherical stopper taking different positions depending on the alinement of the graduated tube and stop.
per, and means in conjunction with thel stopper for withdrawing it from. the'casing.`
2. As anew article of manufacture a thermomete'r of the class described including a graduated tube' and container, a casing for enclosing the graduated tube and container, a stopper of spherical shape attached to the graduated tube for seating yin the casingto close the same and to'support the graduated tube, and means in conjunction with the stopper for withdrawing it from the casing,
said stopper so seating in the casing as to suit the alignment of the graduated tube, stopper and mea-ns for withdrawing the stopper.
3. A thermometer of the class described, comprising a, graduated tube @rrd container, d casing br Said graduated-tube arid @Ongraduated tube in the casing, and means as- 10 socdted with thestopper for withdrawing the same from the caslrlg.
