JAS. nMAnsHconroRATroN, or CHICAGO, ILLINoIsA conformaron or ILLiixroIs@ i THEnMoMETER My invention belongs to that general class of devices known as thermometers and more particularly to an improved mountingfor the well-known type of glass bulb thermometer tubes.- The invention has amongits ob-V jects the productionof a device'of the `kind described that issimple, comp-act,` attra `:tive,.A inexpensive to manufacture and adapted for the easy mounting or assembly ofthe parts. fbi More particularly the same has as an object the'production of a` tube mounting wherein the tube may be mounted and adjusted to provide proper calibration, and which'tube may be replaced as required and the new tube 175i adjusted without requiring the return of the entireinstrument to the factory for re-cahbration. i

The invention has as a further object the production of an instrument of the kind dei scribed that may be easily and conveniently read at a distance and which will not be easily read incorrectly. The invention has as a further objectthe'production of a mounting constructed of'a single stamping or body part designed to protect the tube and 4protect it from'inj ury thereto, the samebeing so formed as to provide for the printing of the scale directly on the mounting without requiring an additional scale to ibe attached thereto'.

and more particularly pointed out in the claims.

Referring to theldrawing inlwhich only one embodiment of my device is shown, the main part'fof the mounting consists of a. stamping Jformed to provide a backfl7 the front face of which provides a space for the imprinting of a scale. At the sides the body" part isoiiset outwardly as indicated at 2 and thence over at 3 and-back as shown at `4v to provide a rib, making the part 1 rigid'and also afording a finish. 'At thev bottom the same is 4pressed or formed outwardlyk as indicated at 5 and then turned over and backas shown at 6. At the top thersame is formed with the face portion 7 spaced outwardly from the Vface of the'partl l and provided with a rib', the extreme edge being turned over as indicated at 9 to correspond with the turned over portion 4 at the sides; v,This gives the` scale. portion 1 and space 7 surrounded or enclosed within the

bead

3, 6 and 8. The part may be `formed in any suitable manner, same` being preferably stamped out or a blank toaV form substantially as lshowir'in the drawing. The portion 11, connecting Jface portion 1 and*- face portion 7, is provided with va struck-up 'portion 10, which leaves an opening l12.`

through which the upper end of the thermometer may be inserted as hereinafter described.` The bottom oroutstanding portion 5 isjpro? vided with an' opening 15. At this opening L' is arranged a sleeve 16 which is provided with the flange 17, the parts being held assembled by welding together or by frictional engage- L p ment. It is generally preferred to rearwardly oisetthe portion-1 at this point as indi cated at 14 so as to permit the sleeve 16 to be set inwardly and center with the thermometer tube.

A thermometer tube 18 provided with the usual bulb 19 is inserted in the sleeve 16 with the upper end extended up through the opening 12. At the upper end l prefer to arl range a felt, rubber or othe-r strip 2O which maintains the upper end of the thermometer tube against displacement. The lower end is centered in the sleeve 16 by a rubber gasket 26, the same being so proportioned as to closely lit theinner Wall of the sleeve, as well as the thermometer tube which passes through the gasket. The tube is thus maintained against accidentalV displacement butV the n mounting is such that itV may beadjusted up by showing the temperatureV of the contents.

VAs shown, the connector 21 isfprovided with a threaded portion 22 and with a chambered extension 23, the parts being so construeted that the thermometer bulb 19 isV positioned within the chamber. The parts are maintained. assembled by a screw 24 or equivalent means. Ordinarily the chamber and theconnectoris filledv with graphite, oil and graphite, mercury or other suitable materialV that will' transmit the heat from the tubular extension 23 tothe thermometer bulb 19. It will be noted that the gasket 26 not onlyk secures the .lower end of the thermometer in the sleeve 16, but that it likewise forms a gasket or packing within the connector and prevents any leakage between the sleeve 16 and the connector.

0n the face ofthe portion 1 of the mount-- ing are arranged scale lines 28.` The scale lines are preferably made of increased widthl as indicatedat 29, and the numerals or scale readings 30 arranged in that enlarged space vand in a contrasting color. This permits the readings to becomparatively large sothat theV n: same are easily ready even from a distance.

Intermediate scale lines between the lines 28 may be provided, but generally this is not*` required: as the intermediate readings may be readily7 estimated. In view` of the fact that the tube is readily adjustable on the mounting, these readings'may be printed or otherwise formed directly on the face por-A tion 1, it being my practice to enamel the body part, l and printthe readings directly on'the enamel generally after the enamelv is baked. This affords a permanent scale which cannot becomev disarranged or out of adjustment; VThe. thermometer tube may then be inserted and calibration made, the tube being moved up or down and a 4correct reading as- Vtube which may be. adjusted on the mounting so as to give a correct reading and secure it at that point by means of the gasket 26 and retainer 20. It will be notedy that the tube lies below the faces of thebead 3 so, that it is protected to a considerable degree. By offsetting the portion 7 the portion 11 may beutilized to provide the struck-up portion 10 and likewise there is provided-a space upon which the manufacturer may imprint his "name and trade-mark or other matter, or.

thisl space `may .be utilized by the manufacturers customer tov provide his identifying marks.V This isvery desirable as the manufacturer of'` apparatus equipped with Ythe thermometers or the installerof apparatus frequently desire to so mark the thermometer as toidentify their product or work. .lf desired, this 'may ybe applied at the time .of printingv the scale or may be done by applyingra label to the face 7. It will benotedl by referringV to Fig. 2 that if a label is applied tothe-face?, the same isiprotected to a more orlesseXten-t by the bead 8 surrounding the face 7 atthe sidesand top. Having thus. described my invention, it is obvious that various immaterial modifications may bemade in the same without departing. from .the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown andfdescribed or uses mentioned.

What I claimfas new and desire tosecure by Letters Patent is:
