IMPROVEMENT IN Emacs.

y The Schedule referred to ihthese'Letters Patent and making part of the same.

y Be it known thatI, SAMUnnDgVAN PELT, ofAnin the county of Madison and State of Indi- Hinges; aldl do hereby declare that the 'following isla full, clear, and exact description thereof, which This invention relatcsto improvements in blind and to a doorl and door-trame; i d `Figure-2represents the saine closed, and partly Figure is an elevation of a blind-hinge in the' open position; l

d Figure 4 is an elevation of a part of a blind in the Y Figure 5 isa plan of one part of the blind-hinge.

and'doors or blinds, as in the ordinary way, I propose lit into a round hole, and I Iit them by boring with a partof the hinge to be1 attached, which is secured by For blinds and other light articles, the hinges made. of a single divided cylinder, as in figs. 3 and 4, will vbe suiiiciently strong; but for heavy doors, I propose to employ two or Amore, and connect them by bars D,

andf make the joints in the said bars and the outer' ends of the 'cylinders as in the ordinary hinges, or as represented in figs. 1 and 2..

When the single cylindrical forms are used, they are divided-vertically for about half the length, aud horizontally the other half, the pintle E rising up from the horizontal faeeof the part attached tothe ti'ame, and the other half having a'hole for it.

` F represents cam-shaped studs rising up from the face ofthe part having the piutle', and alongside 4of it, which act in conjunction with corresponding notches in the face of the other part, to hold the blinds open or shut, the said notches and projections being arranged to let the blinds drop down when either opened or closed, but to cause it to rise in either opening or r shutting. This prevents the blinds from being either opened or shutby light currents of air. A

` The pintle is provided with a stud, G, and the part having the hole is provided with a slot, which will admit the lug to'pass throughwhen adjusted to the right position, after which the blindcanno t be taken olf until the slot and lugA are broughtfto coincide again. This prevents the blinds from being blown o i the hinges. y

Having thus described my invention,

What I claim as new, and desire to secure by v
