'l RELEASE-Eremita Specification of Letters Patent. 1 Patented July 9, 1912.

Appuca'nonied January 14, 1911. seriai No. 602,665.

To all whom 'it may' concern:

Be it known that I, WALTER P. MURPHY, a citizen of the United States, residing at Chicago, in t-he'county of Cook and State 5 of Illiois, h'ave'invented certain new and useful Improvements in Release-Rigging, of-

erted uponA the pinoperating lever, which" sometimes results in thev pin lever breaking 20 at a point between its fulcrnm and the loclring pin of thec0upler,thus freeing the pin lever of its weight,f.whereupon it is free v to :fly backfv and strike the' operator.

. The object 'of my invention isfto eliminate 2 5 the liability oftheoperator being struck by the pinv lever, by 'introducing means Ain the- -rigging to' limit the upward and backward movementof the pin. lever; and with this -and minor objects in view, myl invention '30 consistsofithe -parts andv lcombination ofthe parts as .will be hereinafter morel fully' pointed out.

In the drawing, Figure l lis atop plan view l. of theendv of a car',- wit-h parts broken away, with a release rigging embodying my invention 'attachd to the `enrl sill of the car;

vFig. `2 is an enlarged detail view of the.

handand'pin levers broken away with their fulcrum and my improvedv stop; Fig. 3 isa 4Q vertical section longitudinally of the ful .l crum, with associated parts shown Fig.l

2; and Figs. 4 and 5.',are detail views ofthe' castingand stop, respectively.y The numeral 1 represents a, car v broken 'V45 away, 2 the end sill ofthe car,3 the cou# .pler head and 4 the locking pin;

The fulcrum according' to 'my invention," con-sists of a base 5, provided ,with openings' at'each end .through which-,rivetsf-G uced fulcruin be'ringvSeterininat'ing: in an prefer to make it octagonali-soas to provide extend,'whereby the base mayfbe secured to'A .theend sil1. EX ten'ding from said. basegis 3 axhollow .fulcrumlmeinberl 1., having a vre-l tagonal' v end 013'-w 'extension 9.?"1 This exten- "on-m be of an Tfrectan ular sha e but I p l W 'Y g p ment, n wn-1 be noted from Eigenaar-,ree

for. av practically wide range of adjustment of the Stop (to be hereinafter referred to').

. The numeral l0 represents a hand oper-,l ated lever, which is loosely mounted near 6g one end on the bearing 8. It will be-notedfrom. Fig. 8 that the opening 1l inthelever is of greater' diameter than the bearing 8, whereby the lever has a loose lbearing or pivot on said bearing. 'l`his- 1ever,'as stated 65 projectsibeyond the fulcrum bearing' 8 and` has at one end, an upwardly extending hook Vshaped protuberance 12, vupon whichrests' the pin operating lever 13,'-which is also provided 'with' an opening '14 larger than 7(7)'4 'the pivot or fulcrum bearingrwhereby it,

likethelever 10,"ha`s a loose pivot bearing. The `inner end of the pin lever is deflected as shown in Fig. 1 and providedl with aV lreduced portion adapted to pass through 75 the eye of. the locking'pin 4, the extreme inner end of .the lever'being 'bent to form a hook to vprevent accidental disengagement v of the lever from the locking pi' n.`v The onterend of the hand .operated 'lever' 10 80 sags downwardlyto a pointbelow the end sill 2, as shown 'in dotted lines, Fig. 1. The saggingend of the han-d operated leveris arranged in such relation with respect to the end' sill of a car or the corner step of 85 "ai-car to enable the operation of the same through the medium .of the foot ofthe trainman,vso that the train-man can use his lantern while uncoupling or. immediately after-the uncoupling operation. 90 The safety stop .comprises a washer l5 provided withan oct-agonal depression or recess 1G in its underjface, adapted to fit over the octagonal endof the fulcrum mem# bei' 7 asv clearly shown in Figs. 2 and 3. 95'

The numeral'l7 represents a-bolt passing 'through the 4end sill, -the vbaseplate 5, the

fulcrnm me1nber .7,.and lthe washer 15, and provided with .anut 18lwhereby the washer I is-securely clamped ontheend 16 of the 'ful- `100 -crum member.. -As an additional safe guardr to prevent the v nut n18 from becoming loos# ened", I provide' a. cotten pin 19, 'which passes through thefbolt.

Projectingiipwardly'from the` washer'l 10i', is an'- arm 20 provided with. a strengthening rib-.21, said lar-m-,b'eillg-.provided with afstop 22,- over whichlthe strengthenmgrib 21 projeersj 'The 'stop 22,'as5ishiownjin Fig. a, pro;

ath'fof its upward and ackward Inovejects over the piniopratinleverl in the 11 arm 2Q nnglits stop 22 deflected/forward O the center of the Washer 15.

'The oet'agonal bearing of. the washer permits ot' placing the arm 2l with its stop 22, in various angles without .changing the relative position o the washer with referenceto the ieversf: The Washer, while serving its a lock for the stop, aise serves to` keep 'the levers l and 13 on ,the bearing of the fulerum.

As above stated, the pin operating lever,-

v at timee, breaks under stress and tbe usual of injury vtol the operator, due to 'lmetnres of the pin lever is entirely obviatetl inasmueli as the stop 22 limits the upward and 'backward movement of the pin lever so that in tbe eventffof si fracture of the eliaracter above referred to, the lever is stopped in 'its upward and backward movement by the Stop E22.

The portion of the fnlernm member be- Y tween tbe base 5 anal the bearing vS, serves .es a) spacing nieinber to space the levers 'from the enti sill'ef the ear, thus reducing 'tile liability of the levers `banging; by rezison ei? accidental engagement Wit-li the end Sill,

will be understood"bytliose sliilletl in the art.

What I dennis-:f7

` l. A nlcruin for a release rigging comprising a'bearing for the levers et the rig'- ging, zi projection having flat sides extendingnxiellyfrom the bearing, .fr Washeriiaving :i seatliitting over said projection, and a stop projeeting from said washer and eX- tencling` into the path of the pin lever to' prevent un excess npivurdfmovement. of the Said lever.
