Hare's Changing Box was patented on 7 May 1878 (British patent number 1699). Advertising stated: 'By means of this Apparatus a Sensitive Plate can be transferred from the Plate-box to the Camera with the greatest facility, and without the possibility of its being affected by light. Holding a dozen, or as many more Plates as may be desired, it is so arranged that any one of the collection may be removed, exposed in the Cameras, and transferred to its own place again with absolute certainty at the bottom, which is a light-tight slide.' The 5 x 4 inch model sold for £3 15s.
