Abstract
Abstract A swivel lock mount particularly for mounting an operating device,such as a typewriter on a stand in a position such that it cannot be stolen but so that it can be moved backwardly and forwardly, includes a transversely extending lock bar which has openings therethrough through which securing bolts are passed and engaged into the bottom of a carriage of the device to be secured. The lock bars extend through a guide plate having a through slot through which the bar extends. The slot has great transverse and longitudinal dimensions in order to permit the bar to be slid backwardly and forwardly and to and fro for the purpose of positioning the article in any desired operating position in respect to the guide plate. The guide plate is secured to a mounting stand by engagement of a bolt which extends through the mounting stand and is threaded into the plate. A feature of the construction is that the bolt may be enclosed at its underside and by a lock mechanism which engages over the head of the bolt or a nut therefor and which prevents contact of the nut or the bolt for the purpose of disengaging it from its threaded connection to the guide plate so that, once the device is positioned on a mounting stand, it can only be removed by unlocking the locking mechanism.
