ioNiTED sTATEs PATENT orion.
JoHN H. eRoUT AND r. M. RAY, `or New YORK, N. Y. y
Doon-PLATE.
Specification of Letters Patent No. 3,496, datedMarch 20, 1844.
To all 'whom t may concern: v y' Be it known Athat we, JOHN H. GIioUT and FowLER M. RAY, of the city and coimty of New York and State of New York, `have invented a new and `Improved Mode of Constructing Door-Plates; and we do hereby declare that the followingis a full and eXact description, reference being had to drawings annexed, makinga part of this specifications, in which- Figure l is a perspective view of the front part. Fig. 2 is a cross sectional view showing the internal arrangement and the method of attaching the same to the door.
The letters of reference represent corresponding parts in each figure.
A, A, Figs. l and 2, is a portion ofthe door to which the plate is attached.
B, Fig. l and 2, is a thick plate `of transparent glass. y
C, F l and 2, is a frame which we usually make of brass but may be made of iron and bronzed into which the plate B, is set; the same is placed atthe front part "of the door.
D, Fig. 2, is also a transparent plate of glass upon which the'name or other directions is painted in distinct letters.
E, Fig. 2, is a stationary reflecting'- mirror. F, Fig. 2, is a movable reflecting mirror turning on a hinge at ai, in order to change from a vertical to a horizontal position.
G, Fig. 2, a ground glass plate semitrans-` parent admitting a shaded light from the` inside.
H, Fig. 2, is the inner pla-te of the frame into which the glass G, is set and which receive the screw bolts by which the whole is att-ached to the door. l
I,Fig. 2, is a slide `and rod working into a groove out in the door from front to rear for that purpose or formed in the tin casement sustaining some of the glass plates; the rod turning freely inV the slide, and held in by the head at b.
J, Fig. 2, is a shackle bar connecting the movable refiectorrF, with the slide I and acts in changing the position of the former.
K, Fig. `2, is a spiral spring to keep. the slide I thrown forward lifting thereector by the shackle` bar J, to a vertical position intercepting the view through the plate. To place these plates upon doors, we make an opening through the'saane` at any point desired, some what less than the size of the plate, putting the frame platel C, upon the front side, the parts connected therewith passing into the opening; we then place the frame plate H upon the back side-the screw bolts o, c, passing through the saine, secured by the screw nuts b b.
To arrange the plate for day use,the mov able reflector F, is allowed to remain in its natural position determined by the spring K. If for night use, we draw out the slide I, bythe nob al, as indicated by the dotted lines at g, when by a quarter turn of the same the catch pin e, having been drawn through slots in the boss f is buttoned upon the outside ofthe same, holding the slide I, back and keeping the reflector F, in a horizontal position as indicated by the dotted lines at i; admitting light (softened by the shade glass Gr,) from the hall lamp or other light, to shine through the plate, rendering intelligible to persons in darkness without, the name or other directions writtenupon the plate D.
le do not intend to confine ourselves to the use of glass mirrors for reflectors but substitute any polished metal reflectors of any approved construction; nor to the precise form or mode of changing the position of reflector F. The plate I) upon which the name or directions are written may be changed at pleasure, by taking olf the plate H, secured by two thumb screws o, o, and nob (Z, which is also screwed on to the bolt any name notice or direction may be substituted any changed. The same be omitted and paint upon the back of plate B.
We sust-ain the glass plates by cheap tin work soldered to the front frame excepting the movable reflector which is cased in tin at the back side-thehinge being connected `with the other` tin work. Vhat we claim as new and desire t0. secure `in Letters Patent is,- l
