i Leners Patent No. 100,453, dated March 1, 1870.

IMPROVEMENT EIN BLIND-HINGES The Schedule referred to in .these Letters Patent and making part of the sanne.

To` all whom 'it may concern 4 v v Be it known that I.,D. C. SAGE, of Middletown,

county ot' Middlesex, and State ot' Connecticut, have invented anew und improved Blind-Hinge;. and I do hereby declarethat the following is' a full, clear,.and

perspective .view vof the improved.

Similar lettels of reference indicate corresponding parts in theseveral figures.

To enahleotheis skilled in the art-to understand my invention, l will describe its construction and operation.

1n the accompanying drawings- A. represents theswinging lea-f of my improved hinge, which leaf' is constructed with an eye, a, ou one endfor receivingand attaching it to a pintle,p, that is formed upon thestationary portion B of the hinge.

This leaf A is'perforated, for receiving through it the'screlws that secure it to the blind, and at a suitable point, itis also perforated for receiving through it one end -of a stein, E, on which a cam, D, is sel cured.

The stem` E passes loosely through the blind and hasl a knob or handle, j, upon it, by which the cani Dean be turned around, either toward the right orleft hand.`

Above the cam D and on the same side of the leaf A as this cam, is a spring, g, one end of which is se' cured permanently to to the leaf, and the other end, g, is bent, as shown in iigs. l and 2, and 'inserted througha hole, c, made througha` web, C, so as'to l enter either one of two holes e", made into or through a bearing, b, which is formed on one end of a screw-' stem,B. The spring gis applied to the leaf ,so' that its free end, g', will be for ed downward upon the latsuri'ac'e of the bearing b ile the blind is free to swing, and when the blind is in a position to be selcured fast this endI g of the spring g will b'e forced into one of the holes e in bearing-plate b.

The screwstem B is constructed with one end flattened, so as'to-leave upon it a flat semicircular bear- Ving, b, through or into lwhich two holes, e, are' made diainetrically opposite each other in lineV with the said` stem. On this bearing `the web C of the leafA is supported, and from this hearing the pintle 11, which receives the eye a of said leaf, rises perpendicularly.

' It will be seen from the above description, that the web O not only strengthensthe leaf A and affords it awiie firm hearing upon the surface of plate b, but it also keeps the free or locking-end g of spring g 1n place to. enter one or the other of the holes e andlock the leaf. It will also he seen that the cam D can be operated convenientlywhether the shutter or .blind be open or shut, for raising the free end g of spring g out of either hole e', when it is desired to swing open or shut the blind. When the blind is released, the lockingend of the spring willbearupon the iiat face of the plate b and be held by the -web C, through which it passes.

Having'descrihed my invention, What I claim as new, aud desire to secure by Letters Patent, is-
