EZEK'IEL P. PlEROE, OF CAMBRIDGE, MASSAOHUSET'Q AWNING-BLIND-HIFNGE.

SPECIFICATION forming part of Letters. Patent No. 252,895, dated January 31, 1882.

Application filed April 30, 1881.

(Model) To all whom it may concern: I

Be it known that I, E. P. PIERCE, of (Jambridge, in the county of Middlcsex and State of Massachusetts, have invented certain new and useful Improvements in Blind-Fixtures;

' and I do hereby declare the following to be a full and exact description thereof, reference being bad to the accompanyingdrawings,forming a part of this specification, and to the letters of reference marked thereon.

With reference to the accompanying drawings, Figure 1 is an elevation ot'a set of window-blinds viewed from the inside and provided with my improved fastenings or fixtures. Fig. 2 is a similar elevation of halt the window viewed from the outside. Fig. 3 is a perspective view, shown as an awning. Fig. 4. is an elevation of the halfblind thrown open, view at right angles with that of Fig. 2, and a part broken out to reduce the length of the figure. Fig. 5 is a plan of the upper hinge. Fig. 6 is a sectional plan of the lower hinge-that part ofit which attaches to the blind-the tumbler beingin thelilted position thatlcaves the hook or journal part free to pass out. Fig. 7 is a similar sectional plan, showing the tumbler dropped down,in which position it is so turned,

as shown, that thejournal cannot pass out by it. Fig. 8 is a plan of the same part, together with thumb lever or lifter and fingcnpiece T, &c. Fig. 9 is an elevation of the tumbler with the attached cam-loop h, by which the thumblever H lifts it and causes it to turn on a vertical axis: Fig. lO'is an under view of the tumbler. Fig. 11 is an elevation of a bar-fast, which secures the two parts of the blind together when used as an awning. Fig. 12 is a plan of the same. Fig. 13 is an elevation of a keeper for the stay-rods. Fig. 14 is a plan of the same. Fig. 15 is an elevation of the lock or latch, &c. Fig. 16 is a plan of same.

' Like letters refer to the same or correspond. ing parts in all the figures.

The nature of my invention relates to the iniproved construction of the several parts of that class of blind-fixtures which are so applied as to adapt the blind to swing. on vertical arms for ordinary use and on a horizontal axis for awning uses, and for operating and making them secure in the various positions contemplated in their use.

A and B indicate thetwo halvesof the blind. U is the fixed part of the upper hinge, and is provided with ajournal-sockct.

D is the swinging partof the upper hinge,

and has the vertical axisjournal a hinged or pivoted to it, with a horizontal axis atb. Upon the head ofjournal a is formed a spur orlatch,

c, which, when the blind is closed, swings into the recess formed by the projecting spur (Z on the stationary or fixed part 0 of the hinge. The lower hinge has a fixed part, E, carrying ajournal, 6, also a swinging part,f,cham-' bered and slotted. (See Figs. 6 and 7.) A tumbler, Gr, with circular head'g, is pendent upon thumb-lever H by means of a cam-loop,

When the thumb-lever H is let go the tumbler falls into the position shown in Fig. 7; but when in rehinging thelower hinge thejournal 6 passes in through the slot i-it turns the tumbler in passing it into the position shown in Fig. (i; but after passing it the tumbler falls back with a downward-turning motion -into same position again, as shown in Fig. 7. The

cam-loop h, acting on lever H as the journal.

passes in, lifts the tumbler, and when the journal has passed, the tumbler, in falling, is caused by the same cam-loop to turn back into the position shown in Fig. 7.

The bar for securing together the two blinds (see Figs. 11 and 12) is composed of the guidepiece K, latch or catch L, sliding bar M, and button or look N. WVhen .the button N is turned up, as indicated bydotted lines, the bar M may be moved back longitudinally from the catch L, leaving the two halves of the blind freeto be swungopen in the ordinary manner. When they are closed it is drawn forward, as shown in Fig. 11, and then the buttonN being turned down, as-shown in the same figure, it is locked.

Fig. 15 shows the shutter-fastener for securing the halves of the blind both when swung open and when closed. 0 is a hook or-latch projecting outside the blind, and P a similar .one projecting inside. These are furnished IOO with a suitable catch'for each. (See Q, Fig. 15.) The part I is so jointed in connection with part 0 (like a rule-joint) that by pressing down part P part 0 is lifted and unlatched, while the socket It is provided with a stop under part 0, which will prevent its being pressed down so as to lift or unfasten part P from the outside, while both parts are free to lift for latching and unlatching, as described.

Figs. 13 and 14 show a device for holding the stay-rods when not in use. (See Fig. 1.) A cam, t, holds the rod in a. recess or hook, a. Fig. 1 shows the blinds closed in the ordinary manner and fastened with the device of Figs. 15 and 16. The bar-fast of Figs. 11 and 12 is also adjusted ready to open the blind as an awning. tom of the blinds is swung out and the stayrods S hooked to the window easing (see Fig. 3) forawning use. It to be openedinthe ordinary manner, the bar-fast M is unt'astened,

asdescribed, and slid back. Then, fastenings P ()n unfastening the fasts P the botbeing lifted, each half of the blind is opened and swung back. Fast 0, catching upon catch Q upon the building, as in Fig. 15, holds it open.

The parts may be made of any suitable material, usually, however, ofmalleable-iron castings.

I claim- 1. The tumbler h g G, in combination with socket portion f, having slot and pintle e, substantially as described.

2. The lever H,in combination with thecaniloop h, tumbler G, and the parts cf, substantially as described.

3. The pivoted and rotating journal a, coin structed with the latch c, in combination with the part (J, constructed with the projection d and part I), substantially as described.
