One of the illustrations shows a portable outfit for drillingrails; it may also be used for various purposes in the repairshops and yards. The motor and controller are mounted on atruck and power is transmitted to the drill press through theflexible shaft. The drill is attached to a fork or clamp whichfits over the rails. This is much more easily adjusted than an■old man and can quickly be removed. By means of a leverwhich throws different gears into mesh any one of three speedsmay be obtained. The motor and the flexible shaft operate at a. FLEXIBLE SHAFT USED IN CONNECTION WITH CAR WINDOWCLEANING DEVICE.
