INSTRUMENT CAS I NG Filed Feb. 15. 1928 Patented June 3, 1930 .UNITED- lsrArEs PATENT OFFICE i JOSEPH ZUBA'IY, 0F FLINT, MICHIGAN, A-SSIGNOR TO A C SPARK PLUG- COMPANY, 0F FLINT, MICHIGAN, A C GMPANY OFrMICHIGAN INSTRUMENT CASING Application filed February 15, 1928. Serial No. 254,524.
This invention relates to measuring instru--v ments and particularly to the arrangement for assembling an instrument frame 1n a casf ing.
lli
The primary object of the invention is'to provide means for securely mounting an 1nstrument in the casing characterized by economy in manufacture and simplicity in the operation of assembling the parts. Other objects and advantages will be understood from a reading of the following description and an examination of the accompanying drawing.,
ln the drawing:
:Figure l. is aside view partly in section of the parts in disassembled relation.
Figure 2 is a perspective of the casing and bezel.
Figure 3 is a sectional view with parts re` moved.
Figure 4 is a section on line d-l of Figure 1;'
Referring to the drawing the several figures illustrate my invention as applied to a speedometer for which Vuse the invention has been especially designed.
Numeral 5 designates a casing or housing of cup shape having at its open end a por tion 7 of relatively large diameter, there being a shoulder 11 'between the portions of smaller and larger diameter. This shoulder is to receive in abutting relation a frame 13 which is to carry the elements of a speedometer. The frame has secured thereto the usual magnet 16 and there is, as usual, a
- rotary indicating vmember 17 located between the poles of the magnet. Numeral 19 designates a reset stem which, when the parts are assembled, projects through an opening 21 inthe casing. The casing is also provided with a second opening 23 for admitting a driving shaft which is to be ,coupled with a rotor shaft carried by the frame, the rotor shaft operating a rotor Within the speed'cup,A
not shown. The frame also supports the odometer mechanism which is not illustrated except that numerals 25 and 27 are applied to show the axes of the dial wheels. The invention is not concerned with the details of the instrument frame and these need not be further described. The invention has to do v with the means for fastening the frame in the casing. rlhe frame is formed with either an annular flange or with a plurality of lugs, the latter construction being designated by numeral 15. The external diameter of the flange or of the circle defined by the several lugs 15 is such that the instrument frame fits nicely into the enlarged part 7 and the flange or the lugs engage the shoulder 11. The thickness of the frame in the region of the lugs 15 is somewhat greater than the depth of the enlarged part 7 of the casing so that the outer pcrtion of the frame lies slightly outside the outermost part of portion 7 in the casing.
To prevent rotation ofthe frame in the cas= ing, when these parts are circular in outline, the edge of the casing may be struck-up as at 29 and the struck-up portion may be received within a notch 31 formed in the frame member 13. By this means the parts are capable frame 13. it will be seen that since frame 13 projects slightly beyond casing part 7 the dial 33 will be spaced from the outer end of casing 7 and is incapable of contact therewith. 'llhe dial plate will be provided with openings 35 properly positioned to render visible the movable parts of the speedometer and also to render visible the odometer dials in a manner well understood. Preferably there will be a cover glass 37, which cover glass. is spaced from the dial plate 33 by an annular gasket 39. Numeral 41 is a bezel of cylindrical form having at its front portion an inwardly directed ring member 43 bent over to house a compression ring 45. When the parts are assembled the ring 45 is to engage the cover glass 37. The ring part of the bezel is of such axial extent as to encirclethe enlarged part 7 v of the casing 5 and to extend slightly therebeyond. After assembly the inner end 47 is crimped down over the shoulder 11 as shown in Figure 3. By this means the bezel -41- holds in assembled relation the glass 37, gasket 39, cover plate 33, and the frame. @wing to the'fact that the axial extent of the frame 13 is somewhat greater than the depth of the portion 7 ofthe casing when' the inner end 47 of bezel 41 is crimped over the shoulder ll the frame 13 is held firmly against the shoulder ll1.
The simplicity of assembling the several parts need only be mentioned to be apprecia-ted.l The frame is first positioned in the casing, the parts 33, 39 and 37 placed in position, the bezel pushed over the assembly of parts and its inner end crimped into osition behind the shoulder 11. As the E slipped over the casing it holds from transverse movement relative to the frame the arts 33, 39 and 37 and when crimped down ehind the shoulder it securely positions these parts relative to the frame and also secures the-frame with these parts against the shoulder l1. By a single operation, therefore, the several parts including the cover plate and the glass are secured in their proper relation to the frame and the whole assemblyr is firmly secured relative to the casing.
I claim:
l. In a measuring instrument, a casing, said casing having a iared open end of enlarged diameter forming a shoulder between the parts of said casing, an instrument frame having a projecting portion of greater axial extent than the depth of the enlarged diameter part of said casing, a cover glass, a bezel surrounding the enlarged part of said casing and secured externally over said shoulder, said bezel holding the glass and frame in assembled relation with the projection of the frame engaging the shoulder externally.
2. In a measuring instrument, a casing having an open end of enlarged diameter forming a shoulder between its parts of unequal diameter, an instrument frame having a projecting ortion of greater axial extent than the deptll of the enlarged diameter part ofthe casing, a cover glass, a bezel having a front portion engaging said glass, said bezel surrounding the enlarged `part of the casing and clamped over the shoulder exter nally to hold the glass and frame in assembled relation and the projection of the frame against the shoulder internally.
3. In a measuring instrument, a casing having an open end of enlarged diameter forming a shoulder between its parts of larger and smaller diameter, an instrument frame having a projecting portion of greater axial .extent than the depth of the enlarged diameter portion of the casing, a dial plate positioned over said instrument frame, a cover glass, a bezel surrounding the enlarged part of said casing engaging said cover glass and secured to said shoulder externally whereby it serves to hold the dial plate and cover glass in assembled relation with the frame and the frame in assembled relation in the casin against said shoulder internally. l
