To all ,whom/tmayfconcra,

vBe it known thatl," *FREDERIoir Fi." "FAL l' Moi-nc, a citizen of the 4United States'freSQl' ing `at El Reno, in thejcoiintyL of vCa-na'li'an and State Aofv Oklahoma, i have invented ce`r-V tain new and useful Improvements init Arms, of which'the` follo'wing'is af, specifipanying drawingsl' ,j i, K

HThis nvention relates tok c'ertainffimpro'vef cation, referencev to,` the' 'aC'CAIIiments in" cord armsandfhasI 4relation nioref the liabilityfof breakingiLA7 -v The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved cord arm whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise Y more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to de.- scribe the same with reference to the accompanying drawings, wherein Figure 1 is a View in elevation illustrating a bell cord arm constructed in accordance with an embodiment of my invention and in applied position, the coacting bell and operating means being shown in somewhat a diagrammatic form;

Figure 2 is a view in side elevation of the arm unapplied;

Figure 3 is an enlarged fragmentary sectional View taken through the device at the pivoted portions of the rock arm and coactmg swinging arm;

Figure 4 is a fragmentary View in elevation of the outer or free end portion of the rock arm;

COC'M with thefdiainetrically pposedstops Scarl ried by the adjacent end of the tubular member 5, said arm 6 when at the limit of its movement'in one direction overlying the arm- 3 and in parallelism therewith. Thel arm 6 is normally maintained in this position by the coil spring 9 surrounding the member 5 and having its; extremities in requisite engagement with the arms 3 and 6. v

The free end portion of the arm 6 is provided with an outstanding member 10 provided therearound with a circumferential groove 11 in which an end portion of the bell cord C is engaged, said member l() being aligned with the bearing 2 so that during the period the bell is operated by the air bell ringer, the cord C is substantially free of any movement and thereby effectively maintained taut. This is of advantages as the cord C is not jerked or flapped around when the air bell ringer is'in use and thus eliminating the possibility of the cord C being broken.

When it is desired to use the cord C to start the, bell B, initial pull on the cord will swing the arm 6 against the tension of the spring 9 until the stop comes into Contact with a second stop 8 whereupon the arms 3 and 6 will have vunitary swinging movement in one direction. lhen pull upon the cord C is released, the arm 6, under the influence of the spring 9, will automatically return to its first or normal position.

The `arms 3 and (i are maintain-ed in d'elv sired assembled relation through thev merdium of a bolt 12 extending axially through the pin 4 and held in'position by a eonven#rv tional nut 14, the head of the bolt overlying the outer end of the pin 4L and having inter# posed therebetween and Vtheradjacent vportion of the arm 6 the washer 15, said washer Y being of such-*diameter as to have direct contion is susceptible of some change and modi-` tact-with the outer face of the 'pivoted por@ tion of the arm 6.

From the t foregoing description it is thought to be, obvious that a bell cord arm constructed vin accordance with. my; invention is particularly well adapted for use by reason ofthe convenience and facility with whichdit may .be Aassembled andv operated, and it will also be obvious that my inveniication vwithout departing from theprin-V ciples and spirit thereof'and for this reason I do not wish to be understood as limiting myself to the precise arrangement and forl mationl of the several parts herein shown in carrying out my invention in practice eX- cept as hereinafter claimed.

VIclaim: Y .i .c p l. In combination with a bearing for a bell, an arm engaged with said bearing, a second arm, means for pivotally connecting said arms one to the other for relative swing-l ing movement, said second named arm normally overlying the first namedy arm, and

means for maintaining the second arm in such normal position, said second arm being provided with ymeans substantially aligned with the Vbearing for the bell when the second arm vis Vin its normal position for attaching a bell cord thereto.

' 2. In combination with a bearingl for` a bell, an arm engaged with said bearing, a second arm, means for pivotally connecting said arms one to the other for relative swinging movement, said y'second named arm normally overlying the first namedarm, meansv tor maintalning thel second arm .in such nornormally maintaining the second arm inv overlying relationfwithl respect tov the first named arm,rboth of said arms being provided with coacting means whereby the second named arm has limited swinging movement in one direction relative to the rock arm when pull is imposed upon said second arm.'

In testimony whe'reoil I hereunto affix my signature.
