CURTAIN- FIXTURE.

SPECIFICATION forming part of Letters Patent No. 357,714, dated February 15, 1887.

Application filed May 26, 1886. Serial No. 203,281. (No model.)

To all whom it may concern:

Be it known that I, WASHINGTON O. KANT- NER, a citizen of the United States, residing at the city of Reading, county of Berks, State of Pennsylvania, have invented a new and useful Improvement in Curtain-Fixtures, of which the following is a specification.

This improvement is more particularly related to that class of window-curtains which are attached to a roller of the Hartshorn type and secured to oscillating arms, so that the curtain may be raised or lowered in the ordinary manner, orit may be thrown away from the window-sash or dropped in a vertical position, leaving the top of the window clear of obstruction and permitting the lowering of the upper sash for purposes of ventilation.

The object of the improvement is to secure privacy, ventilation, ready adjustment, and the placing of the curtain beyond the effect of the air-currents over the top of the sash when dropped vertically to the full radius of the oscillating arms.

The nature and extent of my invention will be found fully disclosed in the drawings and specification.

Figure 1 represents, in perspective elevation, a window provided with my improvement, showing the curtain-roller in its normal position at the top of the window-case. Fig. 2 represents the same window with the window-curtain partially swung out from the window-sash, in both of which a single cord attached to one of the bracket-arms running over a roller at the top of the case serves to retain the suspendingfixture in place. Fig. 3 represents, in full elevation, a wide storewindow, and illustrates an arrangement of double cords and pulleys for manipulating the suspensionfixture and curtain; Fig. 4, detail front and side elevations of the oscillating bracket-arms; Fig. 5, an elevation of the preferable style of roller used for narrow windowcurtains; Fig. 6, an elevation of the bracketarms, adjustable bar, and curtain-roller detached from the window-casing, in all of which- N A represents the window-case; B, the sash; G, the friction bracketarm; O, the frictionbox; 6*, the bar-head; G set-screw; O", pivotal screw end D, the retaining bracket-arm;

D, the retainer-hole; D bar-head; D setscrew; D, pivotal screw end; E, an adjustable-to-width connecting-bar fitted to snugly move in the heads 0 D"; F, the usual curtainroller; G, curtain; G, rings to curtain-stick; H, cord-roller for narrow curtains; I, singlecord sheaves for wide curtains; I, double-cord sheave for the same; J, operating-cord; J, ring for double cords; J adjusting-cord; K, lock for cord.

The curtain-roller turns in bearings provided in the brackets O D. These bracketarms are pivoted upon the inside face of the window-casing, with the pivot end close to the sash-bead. This mode of pivoting throws the curtain-roller outward, so as to overhang the pivot, and on releasing the cord J from the lock K the action of gravity alone will drop the curtain with its roller from the position shown in Fig. 1 to that of Fig. 3; or, if desired, the curtain may be held at any intermediate point between the two extremes by securing the cord J 2 at the desired limit.

I prefer to make the bracket-arms G D with heads (1 D boring the same to fit snugly to a wire of steel or iron of the proper diameter, adapted to form a rigid connection between the brackets across the width of windows to which the same is applied. Set-screws G D serve to retain the bar in its proper relative relation thereto.

The objection to all prior oscillating-arm curtain-fixtures was that there could be no adjustment to adapt them to the various widths of'windows to which it was desired to apply the same. They could not heretofore, on this account, be manufactured as a commercial article for general sales, but were ordered specially for each application. This made them expensive and troublesome to the curtainhanger and discouraged the use of the same. The desirability of securing top ventilation by the window without having the privacy of the chamber exposed was generally admitted. At the same time in all prior attempts to secure the same there was during high winds a constant tendency for the same to catch the curtain as it hung at some distance from the sash and create an annoying flutter of the same, and to partially expose the interior of the chamber.

ICO

In my improved mode of operating the curtain-fixture all these objectionable features are overcome and the fixture becomes a regular article of manufacture, sold, as the generality of household goods are sold, ready for immediate use. The brackets are pivoted in place and the bar passed through one bracket-head until the other is entered and stopped flush with its outer face. The bar is marked on the entering side flush with the outer face of the head, and is then nicked with a file and broken off, returned to place, and the setscrews D screwed down upon the same.

7 The pivot of one bracket is now loosened and the usual Hartshorn type of curtain'- roller inserted in the bearings OD. The bracket is again swung into place and the pivot-screw reinserted, when the same is securely retained in position until properly released. For ordinary-width curtains the cord J is attached to one side bracket only, as the fixture, when the set-screws are tightened, is as stiff as if it were one integral casting; but for wide and heavy curtains I attach a cord to the bracket upon each side of the window, in the latter case using the single sheave I at one side and a double or wide sheave, I, on the drawing side, connecting the double cords to a ring, J, below the double sheave I, a single cord, J, secured to the same ring, passing down to the usual lock, K, to hold the curtain in any desired position. In the former case I prefer to use a roller, H, as shown in Fig. 5.

I make no claim to a bracketed curtain-fixture per 80, as such curtains were patented as early as December 29, 1868, by A. S. Dickenson, in which the cross-bar, its pivoted arms, and roller-supports were in one integral piece, and could not, therefore, be furnished as an article of manu facture to be kept in stock, but had necessarily to be ordered for each width of window-sash to which it was to be applied. See, also, patent to J. Haux, July 1, 1884, No. 301,120, for a mode of securing adjustable bracket-hangers for roller-curtains to window-frames, in which the hanger-supports are fixtures in the window-frames. The holding-arms are adapted to receive one or more cross-bars, one for the support of the curtain-roller hangers, the other for an independent curtain. The rOller-hangers are adjustable as to width between the same by sliding upon said bar, and are secured in place by set-screws when so adjusted, and are also fix-- tures when thus secured, and do not, as in my 5 cial success by providing, as described, for

their adaptation to all widths of windows in a simple, sure, and inexpensive manner.

I do not confine myself to the special form of bracket-arms shown, but claim any equivalent mode of securing adjustments of width 6 in a stable and suitable manner adapted to support a curtain and permit the raising and lowering of the same within certain limits by oscillating arms independent of the curtain itself, as shown and described.

Having shown my improvement, recited its good points, and the construction of the same, I desire to claim as follows:

1. As an improvement in curtain-fixtures using oscillating arms for the support of the same, the bracket-arms O D, having pivotal points C D, bearings O D, and perforated heads 0 D with set-screws 0 D said bearings adapted to receive spring curtain-rollers F, and said heads adapted to receive and ad- 8 justably hold within the same the width-connecting bar E,in combination with the windowcasing, substantially as shown and described, and for the purpose set forth.

2. The combination, witha window-case, of 8 the bracket-arms having the pivots at their lower ends and provided with perforated heads, the bar E, adjustably secured in said heads, a roller, F, journaled in the bracketarms, a curtain secured to said roller, the pul- 9 leysI I, secured to the window-case, the cords J J, ring J, cord J and lock K, as set forth.

3. In combination with a window-casing, a curtain-fixture having pivoted oscillating arms 0 D, with bearings O D, heads 0 D 9 and set-screws 0 D a width-adjusting bar, E, roller F, and curtain G, as shown and described, the cords J J, secured to the heads G D and led-over pulleys II, a ring, J, cord J", and lock K, whereby the said curtain-fixtures are operated to swing upon the pivots O D, or to be raised or lowered, substantially as and for the purpose set forth.
