This invention'relates' tocertain new and useful in'iproven'ients .in signaling devices.
The main object of the invention relates'to the provision of hardened bearing for the'for- Ward end ot they'armature shaft ofthe motor combinedwith the ynovel means rand structure i'o1."etfecting easyand eiiicient lubrication ot the same, u n y Preferably, the construction is such that lubricant may be supplied lto thisbearing from the exterior of the signaling device and Without removingthe motor cover..l 1
. ther objects'and advantages relate to the details of the structure and form ofthe parts, all as Will more fully appear from the following description taken inconnection with the accompanying drawings' in' which through the signaling device. zo y,
l same as that disclosed'in my i y f plicat-ion, Serial Number 493,498, filed August' 1S, 1921, and vthis invention is more particu- Figure 1 isa longitudinal sectional view Figure 2 is a section on line 2-2, Figure 1. Figure 3 is a section'v on llne'B-S, Figure 2. yThe general structure oi horn or signaling device here illustrated is lsubstantially the larly animprovement upon the structure described and claimed in my copending application, Serial Number 676,749, filed November 24,1923.y l y' A l The sional shown comprisesthe usual resonator -1-, front diaphragm case section -2- and rear-'diaphragm case section-`-4-f. Thecase section 44- carries a U-shaped motor case -5- which may be securedto'the case section in any suitable manner. The rear bearing for the armature shaft 6 of the electric motor yis formed in the U-shaped motor case -5 and any desired means of adjustment may be provided, ypas the same mforms no portion of the invention here claimed. y
The motor shaft-6fextends` forwardly through the vcase section -i-f and has its bearing -7- formed in a hardened sheet -12 of metal such as steel as illustrated, of
substantialy rectangular form and lying in substantially fiat contact With the base of the case section --4- and secured to the case section llin any suitable manner as by rivets The base -9-.- of the case section --4- is provided with two radial grooves -1/1- and -21- formed in any suitable manner as by depressing portions of thecasesectio'n, and
Copending ap'- into a furtherdepressed, and in this illustration, substantially rectangular portion -11-- of the base -9-. y y f Between the hardened steel sheet l2- and the depressedportion -11- of the casing, there is positioned an absorbent disk 1dof felt or similar material for retaining lubricant about the bearing. rlhi's disk has a substantially centrally disposed opening through which the armature' shaft extends.
The steel sheet -12-", in like manner as the basel 2 9- of the casing, is rformed Witlitwo grooves -p--A- and -.15- extending radially or the base 9, andthe groove -14- registers with the groove '-10 y in the base Slso as toiform a conduit extending radially of ythe base -9- and leading tothe depressed portion In like manner, the groove registers (lll with the groove --21ea to form an oil conduit y is ormed with .a cylindrical ledge '17- upon vvhich the motor casing -18-- is telescoped and this ledgel is formedwith perforations 1i-la leading to the respective oil conduits, and thevmotor casing is likewise formed Wit-h perforations # 20* registering with the respective perforations 1Q- so that the conduits leading to the depression '--10- open through the ledge and through the motor casing to the exterior ot' the signaling device, thereby' permitting lubricant to be supplied to the bearing from the exterior of the signaling device without removing the motor Casing -18-.
The armature shaft, in the` usual manner, is provided at its forward end with a cam or toothed Wheel --22- adapted to Contact with a Wear piece on the diaphragm --2l-, the edge of the diaphragm being conined between the case sections -2- and -4rin the usual manner. j
vAlthough I have shown and described a specific construction of device, as illustrative of a perhaps preferred embodiment or my invention, I do not desire to restrict myself to imr lli)
the details of forni or structure of the device as various changes may be made Within the scope of the appended claims.
I claim:
l. A horn comprising an armature shaft, a rear diaphragm case section having a base formed With an opening tor the passage of said shaft, a plate secured to the base of the case section and extending to the edge of the base and having a hardened bearing for the armature shaft in alignment with the opening through the base, a radial groove in the case section extending from the bearing and leading to the edge of the base, and an opening through the case section at the termination of said groove.
2. A horn comprising an armature shalt, a rear diaphragm case section having a base provided with a depressed portion formed with an opening for the passage ol said shaft, a plate secured to the base of the case section and having a hardened bearing for the armature shaft in alignment with the' opening through the base, a radial groove in the case section leading to the edge of the base, and a radial groove in the said plate supplementing the grooves in the base to form a lubricant conduit leading to the edge ot the base and an opening through the case section at the termination of said groove.
to said'ehamber and an opening through the case section at the termination or' said conduit.
4. A horn comprising an armature shaft, a rear diaphragm case section having a base provided with a depressed portion formed with an opening for the passage of said shaft, a plate rigidly secured to the hase of the case section and having an opening through which the shaft extends and forming with said depressed portion a lubricant chamber surrounding the shaft and said baseand plate haringportions spaced apart'to forni a conduit leading' trom said lubricant chamber to 'the edge oit the base lor conveying lubricant said chamber7 said case section having an opening aligned with said conduit permitting the passage of lubricant to the conduit, and a ino-tor casing enclosing the shaft and having an opening aligned With the opening in the case section.
5. A. horn comprising an armature shaft, a rear diaphragm case section having a base provided with a depressed portion formed with an opening for the passage oi' said shaft, a plate rigidly secured to the case section and including a hardened cylinder alined with the opening in the depressed portion and which constitutes the forward bearing for said shaft, and said plate being spaced from said depressed portion to form a lubricant chamber surrounding the shaft, and said base andplate having portions spaced apart to forni a conduit leading 'from said lubricant chamber to the edge ot the base for convey ing lubricant to said chamber, andsaid case section having an opening alined with said conduit to permit the passage of lubricantto the conduit.
In Witness whereof I have hereunto set my hand this 23rd day of February, 1924.
WILLIAM SPARKS.
