EDGAR M. CAIN, OF WILMINGTON, DELAWARE.
AUTOMATIC AIR-BRAKE-OPERATING DEVICE.
Specification of Letters Patent.
Patented March 17, 1908.
Application filed November 6, 1907. Serial No. 400,961.
To all whom 'i t may concern:
Be it known that I, EDGAR M. CAIN, a citizen of the United States, residing at Wilmin ton, in the county of Newcastle and State 0% Delaware, have invented new and useful Improvements in Automatic Air- Brake-Operating Devices, of which the following is a specification.
This invention relates to automatic air brake operating devices, the object of the invention being to provide means including a target or semaphore whereby the brakes of the locomotive and train may be set without any attention whatever on the part of the engineer, the device also embodying means whereby it may be thrown out of operation to enable the engineer to pass by the signal located at the oint where the mechanism for setting the brakes would become operative,
With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated and claimed.
' In the accompanying drawings, Figure 1 is. a front elevation of the locomotive, a
target or semaphore, and the mechanism for automatically setting the brakes of the train.
Fig. 2 is a plan view of the same. Fig. 3 is a detail view of the angle cock. Fig. 4 is a sectional view of the same. In the drawings, 1 designates a locomotive which, for the purposes of this invention, is provided with an air pipe 2 communicating with the train air pipe controlling the brakes, the said ipe 2 being arranged by reference over he pilot '3 and extending aterally to a point adjacent to one side of the engine where it is provided with an angle cock4 controlled by means of alever 5. This lever is normally held in a substantially horizontal position but is pivotally mounted with respect to the casing of the valve or cook and so associated with said valve or cook that it may be swung away from said horizontal position as indicated by dotted lines in Figs. 1 and 3 without opening the valve and per- Initting' the air to escape which would have the effect of setting the brakes.
6 designates a target or semaphore operand 10 from a nearby station.
atively mounted on a suitable post or support 7 at one side of the roadbed and adapted to be operated by suitable connections 8, 9
The semaphore or target 6 is provided with an arm or signal 11 which when moved to a projecting horizontal osition as shown in Fig. 1 lies in the path 0 movement of the hand lever 5 of the angle cock 4. Therefore, when the train reaches the signal stand, the lever 5 strikes against the arm 11, throwing said lever back and opening the cock and thereby setting the brakes, no attention whatever being required on the part of the engineer.
Should the engineer, after seeing the signal, desire to pass by the same, he may do so by lifting the hand lever 5 or swinging) the same on its pivotal connection with t ody of the angle cock, thereby moving said lever out of the way of the arm 11 so that it will pass by said arm without being operated thereby.
The device hereinabove described is simple and inexpensive, may be easily applied to any engine and will avoid many serious accidents, being especially valuable adjacent to junctions, bridges, switches and the like.
The target 6 may be electrically operated by the usual electrical connections employed in connection with semaphores and set in action by the trains themselves.
Having thus fully described the invention, what is claimed as new is Automatic air brake operating apparatus comprising an air brake controlling an le' cock arranged adjacent to one side of tie train and embodying an operating lever or handle adapted to be raised and lowered, and a signal embodying an arm adapted to be set in the path of movement of said lever or handle to turn the same and operate the angle cock when said lever or handle is in its operative position, substantially as described.
In testimony whereof I affix my' signature in presence of two witnesses.
EDGAR M. CAIN.

HARRY EMMoNs, CHARLES M. TOWNSEND.
