Filed Aug. 31, 1966, Ser. No. 576,336 31 Claims. (Cl. 188198) ABSTRACT OF THE DISCLOSURE This invention relates to braking systems and more particularly to improvements in such systems. Among many other possible uses, braking systems according to this invention are particularly desirable for use on railway freight cars, such as hopper cars.

It will be appreciated that hopper cars normally have sloping floor sheets for purposes of clearing the car of coal, or other lading, when the bottom doors are opened. Due to the fact that coal and similar lading is subject to freezing in the car during the winter months, it is often necessary to heat the car to free the lading therefrom. In this connection a number of different types of heating thedia are employed, such as a makeshift bonfire of scrap wood under the car, high intensity infra-red ray lamps located along the sides of the car as Well as thereunder, and high intensity gas or gasoline burners located under the cars, for example. Any one of these methods of heating the cars may not only free the lading but also damage various parts of the car structure due to being operated at too high a temperature rating or for too long a period of time.

Heretofore, brake regulators, or slack adjusters, were located under the car in various positions from the bottom of the cylinder lever to and beyond the latitudinal center of the car. It will be appreciated that anything located in these positions is at the lowest point on the car structure, except for the loading shutes and doors, and therefore subject to heat damage. Further, it will be appreciated that practically all of the double acting brake regulators, or slack adjusters, employ loaded steel coil springs to actuate the brake rigging and remove any excessive slack. The coil springs are particularly vulnerable to heat and a spring annealed, due to excessive heating, renders the slack adjuster inoperative. When this occurs the device must be removed from the car, dismantled and the annealed spring replaced with a tempered spring, thereby causing an expense as well as a time delay. I

Accordingly, a feature of the present invention is the provision of a new and improved braking system which overcomes the aforementioned difficulties encountered with such priar art systems.

As another feature of the invention, there is provided a new and improved braking system which is far superior to existing braking systems, and which is easy to install and operate.

Still another feature of this invention resides in the provision of a braking system which is reliable, compact and efficient.

In order to achieve the foregoing features, the invention contemplates the provision of a braking system comprising a brake cylinder assembly which is mounted on the railway car frame in a position adjacent one end of the car, and a brake regulator or slack adjuster disposed adjacent the same end of the railway car. Lever means are provided for interconnecting the brake regulator and the brake cylinder assembly. The braking system further comprises actuating means for the regulator, and means connected to the brake cylinder assembly for actuating brake means. These means include a body lever having a first end connected to said means connected to said brake cylinder, a truck lever connecting rod connected to the second end of said body lever. Further, a first truck lever is provided having one end connected to the truck lever connecting rod, and a bottom rod is connected to the other end of the first truck lever, and a brake shoe is connected to a central portion of the first truck lever. The braking system further includes a second truck lever having one end connected to the bottom rod, a fulcrum connecting rod connected to the other end of the second truck lever, a fulcrum member mounted on the center sill, the fulcrum connecting rod being pivotally attached to the fulcrum member. A second brake shoe is connected to a medial portion of the second truck lever.

There has thus been outlined rather broadly the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the artrnay be better appreciated. There are, of course, additional features of the invention that will be described hereinafter which will formthe subject of the claims appended hereto. Those skilled in the art will appreciate that the conception on which this disclosure is based may readily be utilized as the basis for the designing of other structures for carrying out the several purposes of the invention. It is important, therefore, that the claims be regarded as including such equivalent constructions as do not depart from the spirit and scope of the invention.

Several embodiments of the invention have been chosen for purposes of illustration and description, and are shown in the accompanying drawings, forming a part of the specification, wherein:

FIG. 1 is a fragmentary side elevation of a railway car incorporating a braking system constructed in accordance with the concept of this invention;

FIG. 2 is an enlarged fragmentary side elevation of a portion of the braking system shown in FIG. 1, and showing in detail the brake cylinder assembly, cylinder lever and brake regulator;

FIG. 3 is a fragmentary plan view of the railway car of FIG. 1;

FIG. 4 is a fragmentary side elevation of a railway car showing a second embodiment of a braking assembly according to the concept of this invention;

FIG. 5 is a plan view of the railway car and braking system shown in FIG. 4;

FIG. 6 is a fragmentary side elevation of a railway car showing another embodiment of a braking system according to the invention;

FIG. 7 is an enlarged fragmentary plan view of the braking system of FIG. 6 and showing the brake cylinder assern'bly, brake regulator, bell crank and related parts;

FIG. 8 is a plan view of a railway car incorporating the braking system as shown in FIG. 6;

FIG. 9 is a fragmentary side elevation of a railway car showing still another embodiment of the braking system according to the invention; and

FIG. 10 is a fragmentary plan view of the railway car braking system of FIG. 9.

In the embodiment of the invention illustrated in FIGS. 1-3, the railway car'may be of any conventional type such as one having a pair of side sills 10 and 12, FIG. 3, a center sill 14 and a horizontally disposed shear plate 16 connected to the sills. As best seen in FIG. 1,

angularly disposed

slope sheets

18 and 20 and a hopper door 22 form the floor of the car, the angular disposition of these members being such as to allow the coal or other lading to fiow through the hopper door during the unloading operation. A slope sheet support 24 is interposed between the shear plate 16 and the slope sheet 18 towards the end of the railway car. At the end of the car, an end post 26 is provided which is attached to the upper surface of the center sill by an end sill 28. A striker 30 is attached to the end of the center sill 14, as shown in FIG, 2.

Still referring; to the embodiment of the invention shown" in FIGS. 1-3, the braking system includes a brake cylinder assembly 32 mounted on the shear plate 16 adjacent the slope sheet support 24. The upper end of a cylinder lever 34 is pivotally connected to the brake cylinder assembly as at 36. The first end of a cylinder lever connecting rod 38 is pivotally connected to a medial portion. of the cylinder lever 34 as at 40. A horizontally disposed body lever 42, FIG. 1, is provided having a first end which is pivotally connected to the second end of the cylinder lever connecting rod 38, as at 44.

As best seen in FIG. 1, a truck lever connecting rod 46 is-pivotall y connected to the second end of the body lever 42, as at 48. A center rod 50 is provided having one end pivotally attached to a medial portion of the body lever 42', as at 52,

Now referring to FIG. 1 there is shown a first truck lever 54 having the upper end. pivotally connected to the truck lever connecting rod and the lower end pivotally connected to a bottom rod 56. A brake shoe 58 is mounted on a central portion of the first truck lever 54 for engaging the railway car wheel 60 as shown in FIG. 1. A second truck lever 62 has one end thereof pivotally connected to the bottom rod 56 and the other end thereof is connected to a fulcrum connecting rod 64 which in turn is connected to a fulcrum member 66, the last named member being mounted on the center sill 14. A second brake shoe 68 is medially mounted on the second truck lever 62 for engaging wheel 70.

As best seen in FIG. 2, a double acting automatic brake regulator or slack adjuster 72 is substantially vertically disposed and has its upper end pivotally attached, as at 74, to a fulcrum bracket 76 which is mounted on the end post 26. Any suitable type of brake regulator may be employed. However, preferred brake regulators are disclosed in the E. C. Mersereau Patent No. 3,001,612 and the Showers and Biscardi Patent No. 3,096,859. A sheave bracket 78 is mounted on the lower side of the center sill 14 and carries a sheave 80. A chain 82 extends from the lower end of the brake regulator 72, around the sheave '80 to the lower end of the cylinder lever 34.

As best seen in FIG. 2, actuating means for the double acting automatic brake regulator 72 includes a pull rod 84 having the upper end thereof attached to the regulator and having the lower end thereof attached to one arm of a bell crank 86, the bell crank being pivotally mounted on a fulcrum member 88 which, in turn, is mounted on the center sill 14. The other arm of the bell crank 86 is connected to the upper end of the cylinder lever 34 through a link member 90.

In operation, movement of the brake cylinder assembly 32 causes movement of the cylinder lever 34 which, in turn, moves the cylinder lever connecting rod 38, the body lever 42, truck lever connecting rod 46, truck lever 54, bottom rod 56, and truck lever 62, thereby actuating the brake shoes 58 and 68. It will be appreciated that movement of the cylinder lever 34 causes movement of the link 90, bell crank 86 and pull rod 84. This triggers the regulator 72 which causes it to either extend or contract as is dictated by the slack in the brake rigging. Such movement changes the position of the lower end of the cylinder lever 34 through the chain 82, thereby maintaining a fixed ratio of the movement of the "brake cylinder assembly 32 with respect to the brake shoes 58 and ('8 regardless of the amount of slack in the braking system.

cil

To simplify the disclosure, like numerals identify similar parts throughout the drawings. In the embodiment of the invention illustrated in FIGS. 4 and 5, the railway car may be of any conventional type such as that hereinbefore described in connection with FIGS. 13, except that the slope sheet 18 is supported by a slope sheet support bracket 92 which is interposed between the slope sheet 18 and the center sill 14. A braking cylinder assembly 32 is mounted on the shear plate 16, as best seen in FIG. 4. A substantially vertically disposed brake cylinder lever 96 is provided and the braking cylinder assembly is pivotally attached to a medial portion thereof as at 98. The cylinder lever connecting rod 38 is pivotally attached to the lower end of the braking cylinder lever 96, as at 100. The brake shoes 58 and 68 are actuated by movement of the cylinder lever connecting rod 38 through the various parts in the same manner as discussed more fully hereinbefore in connection with the embodiment of FIGS. 1-3.

A double acting automatic brake regulator 102 has its lower end pivotally attached to the slope sheet bracket as at 104, FIG. 4. Any suitable type of brake regulator may be employed such as the types described hereinbefore in connection with the brake regulator 72 in the embodiment of FIGS. l-3. The regulator is positioned under the slope sheet 18 and is disposed, in a substantially parallel relationship with respect thereto. A sheave bracket 106 is mounted on the underside of the slope sheet substantially adjacent the upper end of the regulator, and a sheave 108 is carried thereby. A chain 110 is employed extending from the upper end of the cylinder lever 96, partially around the sheave 108 and connecting. to the upper end of the brake regulator 18, as shown in FIG, 4.

The actuating means for the brake regulator 18 includes a trigger 112 extending outwardly of the regulator, asheave 114 mounted on the center sill adjacent the trigger and a cable 116 extending from the trigger, passing over the sheave and connected to the cylinder lever 96, as at 118.

In operation, movement of the brake cylinder assembly 32 causes movement of the cylinder lever 96 which, in turn, moves the cylinder lever connecting rod 38, the body lever 42, truck lever connecting rod 46, truck lever 54, bottom rod 56, and truck lever 62, thereby actuating the brake shoes 58 and 68. Movement of the cylinder lever 96 moves cable 116 to actuate trigger 112 which causes the regulator 102 to extend or contract depending upon the slack or lack of slack in the brake rigging. Such movement changes the position of the upper end of the cylinder lever 96 through the chain 110, thereby maintaining a fixed ratio of the movement of the brake cylinder assembly 32 with respect to the brake shoes 58 and 68 regardless of the amount of slack in the braking system.

As pointed out hereinbefore, to simplify the disclosure, like numerals identify similar parts throughout the drawings. In the embodiment of the invention illustrated in FIGS. 68, the railway car may be of any conventional type such as that hereinbefore described in connection with FIGS. 1-3, except that the slope sheet 18 is supported by a slope sheet support 120 which is interposed between the slope sheet 18 and the center sill 14. A braking cylinder assembly 122 is mounted on the shear plate 16, as best seen in FIG. 6. A brake cylinder lever 124 is provided and the braking cylinder assembly 122 is pivotally attached thereto, as at 126. The cylinder lever connecting rod 38 is pivotally attached to the lower end of the braking cylinder lever 124 as at 123. The brake shoes 58 and 68 are actuated by movement of the cylinder lever connecting rod 38 through the various parts in the same manner as discussed more fully hereinbefore in connection with the embodiment of FIGS. 1-3.

A substantially horizontally disposed double acting automatic brake regulator extends crosswise of the railway car and has its outside end attached to the side side sill as at 131, FIG. 8. Any suitable type of brake regulator may be employed such as the types described hereinbefore in connection with the brake regulator 72 in the embodiment of FIGS. l-3. As best seen in FIG. 7, a rod 132 has one end pivotally connected to the other end of the regulator as at 134, and the other end thereof is pivotally connected to a bell crank 136, as at 138. The bell crank is pivotally mounted as at 146 on a bracket 142 extending from the end post 26. The other arm of the bell crank 136 operatively engages the upper end of the cylinder lever 124 as at 144.

As best seen in FIG. 7, the actuating means for the double acting automatic brake regulator includes a pull rod 146 having one end end attached to the brake regulater as at 148, FIG. 8, and the other end thereof pivotally connected to one arm of a bell crank 148 as at 150. The other arm of the bell crank is pivotally connected to an actuator rod 152 as at 154, the actuator rod being attached to the cylinder lever as at 156, FIGS. 6 and 7.

As best seen in FIG. 6, a bracket 158 having a curved surface 160 is interposed between the slope sheet support and the end post 26. The cylinder lever 124 is provided with a projecting pin 162 for engaging the curved surface 166 to support the cylinder lever in the desired vertical position with respect to its backward or forward position.

In operation, movement of the brake cylinder assembly 122 causes movement of the cylinder lever 124 which, in turn, moves the cylinder lever connecting rod 38, the body lever 42, truck lever connecting rod 46, truck lever 54, bottom rod 56, and truck lever 62, thereby actuating the brake shoes 58 and 68. Movement of the cylinder lever 124 moves actuator rod 152, bell crank 148 and pull rod 146 to cause the regulator to extend or contract depending upon the slack or lack of slack in the brake rigging. Such movement changes the position of the upper end of the cylinder lever 124 through the crank 136 and rod 132, thereby maintaining a fixed ratio of the movement of the brake cylinder assembly 122 with respect to the brake shoes 58 and 68 regardless of the amount of slack in the braking system.

Again as pointed out hereinbefore, to simplify the disclosure, like numerals identify similar parts throughout the drawings. In the embodiment of the invention illustrated in FIGS. 9 and 10, the railway car may be of any conventional type such as that hereinbefore described in connection with FIGS. l-3. As best seen in FIG. 9, a brake cylinder assembly 162 is mounted on the under side of slope sheet 13, as by means of an angle bracket 164. A bell crank bracket 166 is mounted on the under side of the slope sheet 18 adjacent the brake cylinder assembly 162, and a bell crank 168 is pivotally mounted thereon as at 170. One arm of the bell crank is pivotally connected to the brake cylinder assembly as at 172 and the other end thereof is pivotally attached to one end of a substantially vertically disposed double acting automatic brake regulator 174, as at 176. Any suitable type of brake regulator may be employed such as the types described hereinbefore in connection with the brake regulator 72 in the embodiment of FIGS. l-3.

As best seen in FIG. 9, a second bell crank bracket 178 is mounted on the top of the center sill 14, and a second bell crank 180 is pivotally mounted thereon as at 182. One arm of the bell crank is pivotally attached to the lower end of the brake regulator 174 as at 184, and the other arm thereof is pivotally attached to the first end of a cylinder and brake regulator connecting rod 186 as at 188. The second end of the rod 186 is connected to the first end of the body lever 42 as at 44-, FIG. 10. The brake shoes 58 and 68 are actuated by movement of the body lever 42 through various parts in the same manner as discussed rnore fully hereinbefore in connection with the embodiment of FIGS. l-3.

As best seen in FIG. 9, the actuating means for the 6 double acting automatic brake regulator includes a trigger 188 projecting from the double acting automatic brake regulator 174 which engages a trigger actuating bracket 190 mounted on the endpost 26.

In operation, movement of the brake cylinder assembly 162 causes movement of the bell crank 168, which, in turn, moves the brake regulator 174, bell crank 180, cylinder and brake regulator connection rod 186, body lever 42, truck lever connecting rod 46, truck lever 54, bottom rod 56, and truck lever 62, thereby actuating the brake shoes 58 and 68. Movement of the brake regulator 174 causes movement of the trigger 138 due to its engagement with trigger actuating bracket 1190, thereby causing the regulator 174 to extend or contract depending upon the slack or lack of slack in the brake rigging. This movement changes the length of the brake regulator 174 which in effect acts as a link in the system, and thereby maintains a fixed ratio of movement of the brake cylinder assembly 162 with respect to the brake shoes 58 and 68 regardless of the amount of slack in the braking system.

It will thus be seen that the present invention does indeed provide an improved braking system wherein the major braking parts are located towards the end of the railway car, thereby removing them from the point of application of heat utilized for discharging the lading in the car.

Although particular embodiments of the invention are herein disclosed for purposes of explanation, various modifications thereof, after study of this specification, will be apparent to those skilled in the art to which the invention pertains, reference should accordingly be had to the appended claims in determining the scope of the invention.
