i! 11 S n get he la or s a so brake h i hfl te end-we l th 9 481 8 65 18 as shown by the full line position in Fig. 2. It will be noted that the line of pull exerted upon the rod 14 reacts at substantially forty- :hve degrees. thus positively insuring ainst slipp e of the rod 14 towards the right.

Thepawl 24 as herein shown is provided with a relatively wide flat projection 28 adapted to rest upon the upper edge of the teeth 15 when in holding position, while its upper side is provided with an oppositely extending projection 27 normally engaging the depressed right hand surface 28 of the inside of the top of the casing. In this manner, the pawl is positively locked in engaged position, and there will be no danger of the same moving clear of the ratchet teeth due to jolting and jarring of the car.

Theleft hand portion of the top surface of the casing 16 is provided with an elongated recess 30 to receive the projection 27 and connecting with the surface 28 by a diagonal surface 31. When the regulator is actuated, the pawl 24 moves from its full line position toward the left to the dotted line position, whereupon tl: pro- Jection 2'7 is free to move up into the recess 30 and allow one or more of the ratchet teeth 15 to click under the heel 23 of the pawl and thereby absorb all excess travel. When the regulator handle is released, the pawl 24 is carried bodily towards the right and cammed down by surface 31 from its dotted to full line position, and this free movement of app oximately three inches is proportional to total truck brake shoe clearance. In this manne any danger of dragging brake shoes is positively eliminated, for the weight of the live and dead levers will cause the brake beams naturally to drop clear and restore the regulator to the position as shown in Fig. 2.

As previously stated, the housing 16 is pivotally or universally mounted upon the draft sill of the car, whereby the line of pull exerted upon the regulator is substantially coincident with the axis of the rod 14. This universal connection or mounting comprises the pivot bolt 17 which passes thru aslightly enlarged hole: 32, Fig. 4, in a T-shaped bracket 33 riveted or otherwise permanently secured at 34 to the draft sill flange 18. The lower part of the bolt or top of the casing is provided with a rounded or spherical surface 35, and the coacting nut 36 is similarly provided with a rounded surface 37 whereby the housing is free to swing in arm direction. A cotter hole and pin 38 is provided for holding the nut in secured position.

Inassembling the mechanism above described, the pawl 24 is first passed upwardly thru the opening 22 and then the rod 14 moved into place thru the end openings 21, after which the handle 20 is spot-welded or otherwise secured to the end of the rod, or if preferred, the eye for attaching the clevis 13 at the opposite end may be secured to the rod 14 if the rod and handle 20 are integrally made, this being a mere matter of structural detail that can be modified as desired. Itis only necessary to secure the part 33 to the draft sill, after which the regulator is attached thru the hole 32, as above described, and the nut 36 locked in secure position. The present construction therefore provides a universal joint attachment for the regulator whereby the same will yield freely in any direction in the line of resistance as the car body moves up and down on the truck turns relatively thereto.

The operation of the device is of course obvious tothosefamiliarwiththeartanditrequires merelyafullstrongpulltobeexertedtowards the left on the handle. which moves and releases the .pawl from its locking engagement and per- .mits the excess travel in the brake rigging to be absorbed. It should be noted, however, that stop means of some sort such as indicated at the rightof Fig.1. must be provided for most efficient and desirable results. As herein shown, I prefer to attache clevis 40 to the end of pull rod 7, the upper part of the clevis looping over a depending -U-shaped bracket or support 41 riveted or otherwise secured to the flange 18 of the draft sill. This clevis 40 freely slides along its carrier during the operation of the brakes or the regulator and positively prevents a relative movement of the pull rod 7 toward the left beyond certainpredetermined limits, thereby preventing a disturbanceof the angularity of the foundation brake gear and the truck brake rigging at the opposite end of the. car; In other words, when a regulator of the type herein described is applied to each truck of the car as distinguished from one associated with the central foundation brake gear, means must be provided to prevent the taking up of the entire lost motion and a disturbance of the angularity of the other brake levers of the rigging.

In 5, there is shown an attachment for opera ing the regulator from the side of the car. It may not always be convenient 'to pull the regulator from the end of the car due to the close proximity of other cars, and there is accordingly provided a flexible connection such as a chain'42 attached to the clevis and passing around a pulley wheel 43 and thence thru an opening in the outer sill 44 where it terminates inahandring45. Thusbypullingonthisring, the regulator is operated in the same manner as occurs by pulling on the end handle as above described. Whenever it is desired to replace worn brake shoes, itisofcoursetorestoreallthe working parts to full release position as shown in Fig. 1, and this is accomplished by first pulling the handle 20 towards the left and then giving the same a slight quarter turn or twist whereby the pawl rides along the smooth side surface of the rod 14 during its return movement. When the handle is released, it will drop by gravity, thus bringing the pawl and teeth back .into cooperative relation. A single operation thereafter absolutely adjusts the rigging to proper clearance and piston trav From the above, it will be apparent that the present invention provides a simpler construction than that shown in my previous application above identified, and one which will have fewer working parts and accordingly give greater life to the regulator. The parts being universally mounted and provided with sufficient working clearance, there will be no danger of sticking or binding due to uneven pull thereby giving great- ,er efliciency and making the device relatively fool-proof and dirt-proof. g

Without further analysis the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constituteessential characteristics of the generic or speciflc aspects of this invention, and therefore such adaptations should and are intended to be s a member adapted to comprehended within the meaning and range of equivalency of the following claims. a
