'a

The housing 15 is also provided witha ratchet wheel 2 7,jconnected with vthe drum 16 through the ymedium ofthe .shaft 28, which extends through the wall and the' housing as shown. A lever 29 is mounted in the housing-upon the v(shaft 29', which extends throughthe wall 1() into the hous-l ing 14,r this being the shaft 'which carries the pawl 18, so that a movement of the lever 29 willoperatefsuch pawl in the same manner asv movement-"ol v the lever 19. In connection with the foregoing description, reference maybe had'toPatent No. 1,240,324

i' granted to William Dwyer, September 18,

1,917, as thisiinvention contemplates van im"-Y `proved type of construction shown in` this patent,-utilivzing the -mechanism above described in combination with novel means or'overcoming. defects incident to the type of-brake shown in such patent.

It will be observed V'that thelever 29 is v oppositely disposed with respect to the lever f 19, this being for the purpose ,of affording a more convenient meansfor releasing the `pawl 18, and to mount the lever out of the way of operating mechanism hereafter described. l

,- A link 30 is mounted in the housing 15 in yposition to swing `about the axis of the ratchet .vheel27 in the samefmanneras the link 22, and pivotally connected to the link k30r asiat 3l', is a lever 32, adapted toswingj with the link 30, there being aslot .33k in the housing 15 to permitgthis swinging move-vv ment.

34, having a tooth 35 for engagement with fthe ratchet wheel 27, and an eX'tension'36 yprojecting beyond the upper end of the slot Y 33,' to provide a stop to limit the downward `movement. of the lever.

y The lever 32 has a portion 37 extending-at an vangle thereto as shown, and then having an inclined portion 38 extending'.substantially in thepdirection of the ratchet operating yportion 34, 'and having a handle portion 39 turned inwardly toward the ratchet portion 34.A The rEhe levei1 32 is provided at its inner end witha ratchet operating portion or arm angular portion 3,7. of the lever is long turn bygravity to its normally inoperativev Y position as shown when released. Y Y.

To voperate the brakes from the outside ot the car :the hand grip vat the `ireefend" ol' the lever 20 is grasped, and .thesame' oscillated` 'thereby swinging `the lever 2O and the link 22, 'thus kbringing the tooth 25.V into engagement with the ratchetV wheel 17' andV rotating the drum 16 to 'tighten the brakes; Upon release of suoli lever it will return to inoperative position by itsown weight, releasing the tooth 25 from engageV` mentjwith the ratchet.V AThe lever 20 is thus normally in a ldepending position so that the saine is in the most advantageous ppof sition for operation `from the voutside kot.

the cai'. It will be observed that the movement of the lever 2Gcn its operative stroke is toward thefsidc wall ll'of the car, attention being called to this 'tact when consid` ering the movement Lof theflev'er 32. Thisl lever upon the inside offthe car-isl held in a normally upstanding position, and its op erative'stroke is away from the side wall of the car towardy the center thereoisuch stroke of thev lever serving to engage the tooth 35 with .the ratchet wheel to rotate the drum 16 and tighten the brakes, the movement of such lever being limited by the upper end' of the slot 33, so that when. thev lever is released, it will fall to inoperajtive position Lby gravity, thereby disengag-` ing the tooth 35 from the ratchet.

Bythe above described arra'ngementit will be understood that the operating lever 2O on the outside ofthe car is normally in a depending position, Aand its operative stroke is; toward the sidewvaltoi thetcar, whichris the vmost eliticient strokewhen the lbrake is operated from outside"v ofthe car.

'ldfhile the lever 32 on the inside of the car is normally in upstandingposition andiremoved from the heating pipes,and its'operative stroke is away from the wall'of the car ,toward the center thereof,so that the pathoi movement of the lever is entirely unobstructedl and a maximum amount-of force can be applied'thereto without assuming 'an awkward position; and iinallybothin fullflin'es in Fig. 3,"k Y' levers returnV to normally inoperative'position through gravity.

/Vhile I have herein shown and described what I now consider the preferred manner of carrying out the invention, the saine is 1" merely illustrative and I contemplate all changes and modifications that come Within the scope ot the claims appended hereto.

I claim: y

l. In a construction of the character de.- sciibed, the combination `with a railway car having side and end walls, there being obstructions along said side wall suoli as steam pipes, said end wall beingvequipped with a hand brake of the inside and outside type and comprising a rotatable shaft extending through said wall and being provided with a winding drum, and ratchet wheels adjacent the inner and'outer ends 'of said rotatable member,v said ratchet wheels being movablein a clockwise direction withreference to said side wall to wind the brake chain on said drum, said brake being' provided with inner and outer housings having openings on their under sides to permit access to said ratchet wheels; of a depending lever arranged at the outer side of said end wall and having pawl means adapted to rotate said ratchet wheel to wind said brakechain when nioved'in a direction toward the plane of said side wall; and a'continuous lever on the inside of said car, extending through the opening at the bottom of the inside housing, said lever beingl inclined upwardlybetween the side wall and adjacent housing to clear the obstructions on the side wall, said lever being accessible above said housing and having pawl means associated therewith adapted to rotate the inside ratchet wheel to wind' the chain when the lever is'moved in a direction away from the plane ofsaid side wall.

2. In a hand brake mechanism of the inside and outside type, comprising inner and outer housings, and a rotatable member ex-` tending into said housings and having similarly disposed ratchet wheels thereon' adjacent its opposite ends, said rotatable mein ber having means providing a winding drum, and said inner and outer housings having openings at the under sides thereof permitting access to the ratchet wheels; of a lever` extending into tliepopening in the under side ot one ot said housings and having pawl` means adapted to rotate the related ratchet f wheel to wind the chain when moved in a direction away from a verticalplane extending through and coincident with said' rotat` able member; and a curved leverextending into the opening on the under side' of the other of said housings, said lever havingA pawlmeans adapted t0 rotate the related ratchet to wind the chain when said latter lever is moved in a ldirection toward Said vertical plane. v f

3. In a hand brake mechanism, .the coinbination with a winding drum; of means for' rotating` said drum to effect application ot' the brakes, said means including a ratchet member rotatable about a horizontal axis; and a pivoted, toothed operating member oo l forA said ratchet member, said operating member being swingable about said hori- Zontal axis, the toothed portion of said o 3- f' and effect 'winding ofthe drum and movable in a reverse direction to disengage the toothed portion from said ratchet member;V

and stopy means for limiting the-range of movement Vof said lever in both directions. and servingto dispose the majorportionlof said lever above the pivotal laxis thereof during said entire range ot v movemeiit,' e whereby the weight ofsaid lever when re- "f leased effects disengagement of said toothed portion from said ratchetvmember.4v i

Inwitness that I claim the foregoing I have hereunto subscribed my name this 20th day of June 1924.`
