The prisms were to be enclosed to prevent dust and moisture settling on the surfaces / For an improvement in prismatic telescopes J.H.Barton and binoculars. The prisms are supported in plates which have circular holes to allow the light rays to pass. The plates are secured to the bodies by small screws which allow a measure of adjustment / To improve upon earlier telescope patent 4835/1888 granted to and Dr. Schroder Improvement consisted of provision for collimation and protection of the user from recoil. 6447/ To further improve upon patents 4385/1888 and 21120/1903 by construction of cross hairs. 3810/ For an improvement in connection with A.Woods photographic exposure shutters known as Self-Closing Focal Plane Shutters.
