H. L. TONKINSON AUTOMATIC- TRAIN STOP Filed July 1, 1925 (Tue mag I Patented Nov. 33 1925.
HARRY L. TONKINSGN,
OF TEXARKANA, TEXAS.
AUTOMATIC TRAIN STOP.
Application filed July 1, 1925. Serial No. 40.858.
To all whom it may concern:
Be it known that I, Hahn; L. TONKIN- SON, a citizen of the United States, residing at Texarkana, in the county of Bowie and State of Texas, have invented (-erta'in new and useful Improvements in an Automatic Train Stop, of which the following is a specification.
The present invention relates to an automatic train stop, and has for its principal object to provide means for releasing the air from the train line of a car, train of cars, or the like when they become derailed so as to prevent the'train from piling up one car on another as so frequently happens under present conditions when one of the cars becomes derailed.
Another very important object of the invention is to provide a device of this nature which includes a pipe in communication with the train line, having thereon a breakable closure cap with a .eross bar rigidly attached thereto so that should the train or a car thereof become derailed, the cross bar will engage with the rail or other part of the road or track and causethe bre: king of. said breakable cap thereby allowing the escape of air from the train line and cause the application of the brakes on the entire train;
A still further very important object of the invention is to provide a device of this nature which is exceedingly simple in its construction, eflicient and reliable in operation, inexpensive to manut'acturerand install, and otherwise well adapted to the purpose for which it is designed.
Vith the above and numerous other objects in View as will appear as the description proceeds, the invention resides in certain novel features of construction, in the combination and arrangement of parts as i will be hereinafter more fully described and claimed.
in the d rawing Figure 1 is a side levation of a car truck showing my invention associated. therewith, Fig. 2 is a front elevation of the device,
Fig. 23 is a side elevation thereof showing portions in section, and
Fig. 1 is afhorizontal section taken substantially on the line -l4 of Fig. 2 looking downwardly.
Referring to the drawing in detail it will be seen that lesignatcs an air train line, emergency air line, or brake air line and a valve (3 is mounted therein and communicated with a flexible hose 7 which in turn is connected to a relatively short length of tpipe 8. An elbow 9 is mounted on the lower end of the pipe section 8 and is in communication with another elbow 10 mounted on the upper end of a pipe section 11. The parts 8 to 11 inclusive are mounted on the truck as is indicated to advantage in Fig. 1 in any suitable manner. The lower end of the pipe section 11 is threaded externally and receives a breakable cap 12 having tool engaging lugs 13 thereon provided with a groove 14 in the lower end thereof for re? ceiving a cross bar 15. A bolt 16 pierces the cap 14 and has its head counter-sunk in the interior thereof as is clearly shown in Fig. 3. This bolt also pierces the bar so that a nut 17 may be applied to the lower end of the bolt and screws up for rigidly engaging the bar 15 in the groove 14 and to the cap 12.
This cap 12 is preferably constructed of cast iron, although any other suitable breakable material may be utilized. As an example, it is desired to point out that should thetruck shown in Fig. 1 become derailed the cross bar 15 would engage with the rail and be swung because of the Weight of the truck or the car or the like mounted thereon, thereby causing the breaking of the. breakable cap 12 so that the air from the air line 5 could escape through the hose 7, pipe section 8, elbows 9 and 10, and pipe sect-ion 11, thereby applying the brakes to the entire train, if there is a train or to the individual car if only one car is being used at that time.
It is thought that the construction, operation, and advantages of the invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed .in detail merely by Way of example since in practice it attains the various features of advantage enumerated as desirable in the statement of the invention and the above description.
The lugs 13 may be used to clamp the cap 12 to the truck or other stationary part so as to insure and lock the cap from turning.
It is apparent, however, that numerous changes in the details ofconstruction, in the materials, and in the arrangement and combination of parts may be resorted to withoutdeparting from the spirit or scope T of .the invention as hereinafter claimed or tion seated in said groove, and a fastening sacrificing any of its advantages. element securing the bar in the groove and Having thus described my invention, what to the cap. 10 I claim as new is z In testimony whereof I aflix my signa- I A'device of the class described including ture.
