Description
Nov. 5, 1929. c. w. WEISENFELS INSTRUMENT MOUNTING Filed Sept. 14, 1927 INVENTOR C.-W.WEISENFELS ATTORNEY Patented Nov. 5, 1929 UNITED STATES F'VPVATTVENT OFFICE CHARLES W. WEISENFELS, OF ST. LOUIS, MISSOURI, ASSIGNOR TO AMERICAN THER- MOME'IER COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI' INSTRUMENT MOUNTING Application filed September My invention relates particularly to the means for securing a thermometer to the 1 panel of a stove door but may be capable of other applications. Heretofore it has been customary to fasten the back of a thermometer casing to the lining of the stove door by screws, the front end being allowed to project a slight distance through an opening in the panel. This not only requires considerable labor in assembling but fails to secure a satis factory tight joint between the panel and the casing. Furthermore, owing to the liability of the lining to spring, the distance which the casing projects cannot be accurately regulated. In carrying out my invention I clamp the material of the panel between a flange on the thermometer casing and a locking ring which bears on the rear of the panel, preferably at a point beyond the flange.
In the accompanying drawings, which illustrate one form of instrument mounting in a stove made in accordance with my invention, Figure 1 is a front View of a thermometer casing and a portion of a door to which it is applied; Figure 2 is a section taken on the line 22 of Figure 1, the casing and locking ring being in elevation; Figure 3 is a section through one edge of the casing and locklng ring; and Figure 4 is a rear view of the casing and the ring on a slightly reduced scale.
The door panel, indicated at 5, is provided with a lining 6, secured thereto in any usual manner: The thermometer casing is composed of an outer part 7 and an inner part 8 telescoping together. Formed on the front edge of the, part 7 is a duplex flange 9, the outer part of which bears against the front face of the panel 5 and the inner part of which bears against the cover glass 10. The front edge of the part 8 of the casing bears against the dial 20 on which the thermometer calibration 21. This dial is separated from the cover glass by a spacing ring 22. Formed in the part 8 are openings 11, preferably four in number, into which tongues 12 punched from the part 7 pro ect to secure the two parts together.
Formed on the casing, and preferably on the inner part 8, is a pair of diametrically 14, 1927. SerialNo. 219,425.
opposed lugs 13 adapted to pass through recesses 14 formed in the clamping ring 16 and engage with cam faces 17 on the ring when the latter is rotated. The clamping ring is provided with aflange 18 projecting beyond the flange 9 and having a down turned edge 19 bearing upon the panel 5. By rotating the ring to a greater or lesser degree any desired clampmg pressure may be secured, and owing to the fact that the contact of the ring flange with the panel is beyond the flange 9 a certain amount of resilience is secured in the locking means owing to the spring of the panel or the flange 18 or ofboth. This permits securing sufficiently firm clamping over several degrees range of rotation of the ring and thus facilitates proper application and reduces likelihood of suflicient movement under shipping and service conditions to loosen the thermometer in the panel. r.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. In a dei ice ofthe class described, the combination with a panel having an opening therein, of an instrument casing extending through said opening and provided with a lug and an outer clamping flange, said flange bearing against the front face of the panel, a clamping ring cooperating with the casing and panel, said ring having a body portion rigid in the direction of the applied clamping pressure and having a passage for the lug and a cam face engaging with the lug, and a bearing flange carried by said ring, said flange being resilient in the direction of said pressure. I
2. In a device of the class described, the combination with a panel having an opening therein, of an instrument easing extending through said opening and provided with a flange bearing on the front face of the panel, said casing being provided with lugs, and a rearwardly extending locking ring surrounding said casing and having passages for said lugs, said ring having cam faces on its rear edge bearing on the panel, said cam faces cooperating With said lugs to force the ring against the panel.
3. In a device of the class described, the combination With a panel having an opening therein, of an instrument casing in said opening, said casing being formed of two parts telescoping together and connected by inter locking parts, a duplex flange on the front part of said casing, one part of said flange bearing on the panel and the other retaining the instrument cover glass, a lug on the rear part or" the casing, a locking ring surrounding the casing and having a cam face bearing on said lug, and a flange on said ring bearing on the panel at points beyond the points at which the casing flange bears on the panel, said ring flange being separated from the panel adjacent to the casing flange.
In testimony whereof, I hereunto affl; my signature, this 10th day of September, 1927.
CHARLES W. WEISENFELS.
