v, HIERGESELL THERMOMETER Filed Sept. 1, 1
y INVE TQIT/ ATTORNEY Patented Mar. 19, 1935 1,995,g50f g a THERMOMETER Valentine Hiergesell, Philadelphia, =Pa., magnet to Ii -B Instrument- Pat, a corporation of Pennsylvania Application Scptemberl, 1934,; Serial Naming 4 Claims.
This invention relates to thermometers and like instruments where a mercury column or tube is to be held in specified relation to graduations or scales, and the invention has for an; object the provision of novel means for retaining the tube in fixed relation to the graduations in order that a correct reading of the instrument may be had, that is to say, that the column of expansible material within the tube will rise or fall so that the top of the column may be exactly positioned with respect to the graduations.
It is well known that in instruments of this kind the tubes containing the expansible material become dislodged and their position is shifted with relation to the graduations and it is not always possible to determine where they should be located when replaced.
This invention insures the proper positioning of the tube and includes novel means for preventing shifting of the tube and furthermore, in the event of the tube being displaced, which is It is a further object of this invention to provide a thermometer or instrument of the character indicated in which the fastening for the tube is associated with a plate. which may have graduations thereon with relation to which the expansible material in the tube moves, including means for partially embracing the tube and anchoring the embracing means so that accidental disengagement of the said means for the tube is obviated.
It is a still further object of this invention to provide an anchoring or retaining device of the character indicated that is of simple construction although durable and eflicient for accomplishing the result.
With the foregoing and other objects in view. the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views and in which- Figure 1 illustrates a view in front elevation, showing one embodiment of the invention;
Figure 2 illustrates a sectional view on the line 2-2 of Fig. 1; v
Figure 3 illustrates a sectional view on the line 3-3 of Fig. 1;
Company, Philadelphial'f Figure 4 illustrates a view in elevation of a fragment of the plate on which the tube is mounted;
Figure 5 illustrates a view in elevation of a fragment'of the tube at the upper end thereof; and
Figure 6 illustrates a plan view vof the tie by which the tube is anchored to the plate..-
"1 H ngings Preferably the invention is associated with a 4 this embodiment of the invention, has a recess 9 near its upper end to form a clearance for the inwardly extending lugs or; ears 10 which are formed when the material of the plate 10 is punched or struck out to form the aperture 11 in which the head 12- of the tube 13 is located,
It is shown that the head 12 has an annular roovel4, in producing which two annular beads or ribs are formed, and the said groove constitutes a seat in which the cars 10 are lodged when the tube is placed in position on the plate and it also forms a seat for the clip or tie 15 which partially embraces the said'tube, it being shown in Figure 2 that the tie has its ends doubled around the ends of the ears andthat they lie against the ears. The beads of the tube engage the edges of the ears and shifting of the tube longitudinally is prevented so long as the tie is v in engagement with the tube and the said ears.
Near the lower-end of the tube and plate another tie such as 15.is employed, which embraces the tube and has its ends extending through an aperture in the plate with the ends of the tie doubled under the plate in firm engagement therewith sothat the tube thus anchored will not vibrate or dislodge from its fixed position.
Obviously, the inventor does not wish to be restricted with respect to the element with which the plate is associated as a. base or support, but in this embodiment the plate is secured to the base by fastenings 16 such as screws or the like. Owing to the fact that the plate may be punched and shaped by well known metal working processes and that the head of the tube may be shaped during the formation of the tube, the device embodying the invention may be produced inexpensively and expeditiously. V
I claim: 1. In a thermometer, a plate having an aperture with ears extending transversely thereof between the upper and lower edges of the said aperture, a tube having a head with spaced beads ing the head and holding its beads in the aperture of the plate. v
2. In a thermometer, a plate having an aperture with ears extending transversely of the apertures between the upper and lower edges of said apertures, a support for the plate having a recess into which the ears extend, a tube for expansiblematerial attached to the plate and having an annularl ygrooved head seated inthe aperture of the plate with the aforesaid ears in the groove, and a tie seated in the groove and partially' embracing the head, the ends of said tie being anchored to the aforesaid ears. 3. In aithermomieter, aplate having an-aper- -tur'e.;and{.ears'integ"ral with the plate-extending transversely of the' aperture between the upper and lower edges thereof, a thermometer tube having a circumferentiallygrooved enlargement, i
lic tie partially embracing the enlarged portion of the tubeandseated in the groove thereof,
the 'ends-of said tie being doubled upon the ears and operative to retain the tube in asssembled relation to the plate.
