Diaphragms
Vestibule Diaphragm
Adlake Diaphragms are the result of long years of experience in helping the railroads of the country overcome the problems which develop under all kinds of operating conditions. A diaphragm must not only meet the mechanical needs of car construction and operation, but resist all weather conditions as well. Material meets FRA 49 CFR, Part 238 & SMP800C.
Because a diaphragm is mounted at the extreme end of a car, it is subjected to strain in several directions. As a result, it has been found that if there is not absolute freedom of movement, the belting first shows wear at the top corners where there is a tendency for it to wrinkle. To minimize this wear by giving the greatest freedom, the Adlake sectional top diaphragm was developed whereby the top section is independent from the legs. If the top deteriorates from weather conditions, it can be replaced without loss of the two legs.
The Adlake sectional top is made with a slope to prevent accumulation of dirt and debris, and to permit water or snow to run off. This increases the life of the belting and keeps down replacement costs.
The following diaphragms are the most commonly used styles. Other models are available. New designs can be developed to meet your needs in car construction or service.
Single-Fold Sectional Diaphragm |
Two-Fold Sectional Diaphragm |
Diaphragm Attachments
Adlake Diaphragm Attachments are designed to attach directly to the car
body and are arranged with slotted machine screws and spring cotters so
that by removing three of these spring cotters on either side of the diaphragm,
the face-plate may be swung out away from the car to allow for the removal
of the lower buffer mechanism. This saves considerable time if repairs
are required at this point.
