T 0 all wiz-0m. t may concern Be it known that I, ERNEST RICHARDSON, a citizen of the United States, residing at College Hill Borough, Beaver County, and State of Pennsylvania, have invented new and useful Improvements in Thermometers, of which the following is specification.

My invention relates to thermometers in connection with suitable mountings therefor. The object-of this invention isr to provide for thermometers suitable mountings adapted to contain advertising matter.

Referring to the accompanying drawing, Fig. 1 is a front elevation of one form of my invention; Fig. 2, an enlarged rear elevation of the'lower part of Fig. 1; Fig. 3, a section on the line III-III of Fig, 2; Fig. 4, a similar section of a second form of my invention; and Fig. 5, an enlarged detail of a part of Fig. 4.

0n Figs. 1, 2, and 3 of the drawing, I show a stamped sheet-metal frame having the plane body 1, and the endless flange 2 around its edges. I arrange a thermometer on the frame which has ample space for advertising matter as shown.

In a suitable opening in the body 1, I mount the outer end of the shaft 3, which carries the hand or pointer 4- which travels over suitable temperature indicia on the outer face of the body. kThe rear end of the shaft 3 is mounted inthe bracket 5 secured to the rear face of the body by the screws 6. A thermostatic coil or helix is mounted between the body 1 and the bracket 5,-one end of the helix being secured to the shaft 3 and the other end to the post 7 secured to the back of the body 1. y

The pointer and the indicia are covered by a suitable transparent cover glass 8 mounted on a spacing ring 9 resting against the outer face of the body 1. A sheet-metal casing 10 surrounds the ring 9 and has its outer end turned inwardly so as to engage the outer face of the cover glass 8 and its inner end provided with tongues 11 which extend through holes 12 in the body 1 and are bent or clinched aga-instY the rear face of the body. 'Ihe frame is preferably covered with a coat of enamel 17.

In Figs. a and 5, I dispensewith the separate spacing ring and provide in its place the Lnnnlar shoulder 13 integral with the body 1a. An annular bead 14C also integral with the body 1 extends out in front of the OF COLLEGEHILL BOROUGH, PENNSYLVANIA.

cover glass 8. This bead provides a seat for the sheet-metal ring 15 which has a U- shaped cross-section permitting it to t the said bead and have its inner edge rest on the outer face of the cover glass. rlhe ring may be secured to the body 1fL in various ways, as by means of the bolts 16 which 'pass through the ring 15 and the bead and have their heads on the ring and their inner ends in the nuts 18 in the hollowside of the bead.

rIhe frame may be supplied with` ventilating openings of any type for admitting air to the interior of the frame. I have marked these openings 19.

I claim- 1. A thermometer kcomprising a sheetmetal frame with a marginal flange forming a hollow casing with the rear side open and having a round bearingppening, a bracket lying on the inner face of the frame and wholly within the same and having a bearing-opening in alinement with the otherI bearing-opening, means adjacent to the opening in the bracket for securing the latter to the frame, a shaft mounted in the said openings, a pointer on the outer end of the shaft beyond the frame, there being tem perature indicia on the outer face of the frame (5o-extensive with the range of the pointer, a thermostatic coil between the frame and the bracket, having one end Xed and the other end attached to the shaft, a cover glass for the pointer, means spacing the glass from the pointer and indicia, and a ring attached to the frame and securing the glass in lined relation to the frame.

2.'
