Application filed March 18, 1897. Serial No. 628,222. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, JAMES G. PENNYCUICK, a subject of the Queen of England, residing at Toronto, in the county of York, Province of Ontario, Dominion of Canada, have invented a certain new and useful Design for Vault-Lights, of which the following is a description.
    My invention related to a new and improved design for vault-lights and is illustrated in the accompanying drawing, wherein--
    Figure 1 is a side view of the vault-light embodying my invention. Fig. 2 is a front view of the same. Fig. 3 is a plan view of the same.
    The vault-light consists of a body portion
provided with the projecting prism A', having the surface B, substantially perpendicular to the body portion A, and the oblique surface C. Connected with the body portion A is an upwardly-projecting circular piece D.
    The essential feature of my design is a vault-light having a body portion provided with the projecting prism A' on one side and on the other side with the circular projection D.
    I claim--
    The design for vault-lights as herein shown and described.
    In testimony whereof I affix my signature, in the presence of two witnesses, this 22d day of April, 1896.
JAMES G. PENNYCUICK.
