LACE-CURTAIN STRETCHER.

SPECIFICATION forming part of Letterslatent No. 680,301, dated August 13, 1901'.

Application filed February 1, 1899. Serial No. 704,085. (No model.) v

T @ZZ whom, it may concern:

Be it known that I, JAMES C. WHIPPLE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and nseful Improvements in Lace-Curtain Stretchers, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, suicient to enable those skilled in the art to which it pertains to understand, make, and use the same.

The invention relates to that class or kind of lace-curtain stretchers which are designed to be set up for use and folded or taken down when not in use.

The object of this invention is to obtain a lace-curtain stretcher which shall be neat in appearance, not liable to get out of order, and of moderate cost to make.

In lace curtain stretcher-s of the kind l named, side rails composed, respectively, of

two bars joined together at their inner and adjacent ends are secured at their outer ends to end rails, thereby obtaining a rectangular frame, such frame being made adjustable by the pivotal connections at the meeting ends of the side and end rails being made through slots. In order to construct the side rails of light material, it is necessary to provide specially-constructed hinges for joining the bars together at the adjacent ends thereof in the side rail wherein such bars are hinged together. It is also necessary to provide special mechanism for joining together the adjacent ends of the bars forming the side rail where such bars are not hinged together, and it is further necessary to provide a cross-bar and means for securing it near its ends to the side rails at or adjacent to the joined ends of the bars constituting such side rails; and this inventionY comprises, first, a specially-constructed hinge for joining together adjacent ends of the bars forming a hinged side rail, preferably used for one side rail of the stretcher, and for securing one vend of the cross-bar to the hinge and to such side rail in a manner to prevent sagging of the side rail as well as any bowing inward thereof; secondly, amechanism for securing together adjacent ends of the bars forming a side rail whereof the bars are not hinged together, such side rail preferably forming the remaining side rail of a stretcher embodying this invention, and mechanism for securing the end of the cross-bar to such connecting mechanism and to the adjacent ends of the bars forming such side rail, and, thirdly, the combining of the foregoing-named hinge and mechanism, respectively, with the respective side bars named.

In the drawings referred to as forming a part of this specification, Figure l is'a plan View, on a smaller figure than are the remaining figures of the drawings, but not to scale, of a lace-curtain stretcher embodying this inventon; Fig. 2, a bottom plan view of the adjacent ends of the bars forming one of the side rails of the curtain-stretcher; Fig. 3, a bottom plan view of the adjacent ends of the side bars forming the other (and the hinged one) side rail of the curtain-stretcher; Fig. 4, an elevation on line 4. of Fig. l viewed in the direction indicated by the arrow; Fig. 5, a vertical sectional View on line 5 of Fig. l Viewed in the direction indicated by the arrow, and Fig. 6 is a bot-tom plan View ofa modification of the connecting mechanism illustrated in bottom plan view in Fig. 2.

A reference-letter applied to designate a given part in one figure of the drawings is used to indicate such part throughout the several figures wherever the same appears.

A and B are the side rails, and C D the end rails, of a curtain-stretcher embodying this invention. Side rail A comprises bar a, bar a', and hinge E. Side rail B comprises bars b b and connection F. (See Fig. 2.)

Gis the connecting-bar extending from side rail A to side rail B.

H H are bolts securing the ends of the side and end rails together.

g g are washers on bolts G G and H H, respectively, and g2 g2 are butterfly-nuts on such bolts G G H H, respectively. G G are bolts extending through holes in the hinge E and connection F, as hereinafter more fully shown.

Hinge E comprises plates e e', pivotally joined by pin e2. Plate e is provided with projection or lug es, and plate e is provided with projection or lug c4. These projections or lugs e3 and e4 interlock, as is well illustrated in Fig. 3 of the drawings.

IOO

g is a hole in projection or lug e2, through which the bolt G extends when connectingbar G is to be secured in place to the under side of rail A, with the hinge E interposed. When such connecting-bar is so secured in place, the projections e2 and el are pressed firmly by such connecting-bar G against the under side of bars a et by the setting of the nut g2 on bolt G', and great rigidity is thus ecured in the hinged connection of such ars.

Connection F comprises plate f, bolts G G2 G2, and Washers g' g', with the butterfly-nuts g2 g2 on such bolts, respectively. The plate fis provided with the holes f f for bolt G and one of the bolts G2 to pass through and with the slot f2 for the remaining bolt G2 to pass through.

The connecting-bar G is secured in place to side rail B by bringing such connectingbar up against the under side of the plate f of connection F, as is well shown in Fig. 4 of the drawings, passing the bolt G' upward through the connecting-bar and plate f and through the bars b b', (between the ends of such bars,) and then placing the washer g on such bolt, wit-h the butterfly-nut g2 firmly set in place.

The connection F is secured in place and to the bars b b by the bolts G2G2, (see Fig. 4,) passing through holes provided therefor in the respective bars and through the plate f, (one of such bolts passing through hole f' and the other through slot f2, as shown in Fig. 2,) and then setting the buttery-nuts g2 g2 firmly in place on such bolts.

In the modification of connection F, which is lettered F in Fig. 6 of the drawings, plate f3 is provided with hole f for the bolt G to pass through, as in plate f of connection F, and with the slots f4 and f4 for the bolts G2 G2 to pass through. This plate f2 is secured to the bars b b of side rail B by the bolts G2 G2, passing through the slots f4 f4, respectively, and through the bars b b', such bolts having thereon the washers g' g' and butterfly-nuts g2 g2 in the same relative position and in the same manner as is shown inFig. 4 relative to connection F. In the use of this modification, as well as in the use of the construction illustrated in Figs. 2 and 4, bars b b' can be folded parallel to each other upon taking out the bolts H I-I at the ends thereof, respectively, without taking bolts G2 G2 out of such bars b b', it being simply necessary to loosen the butterfly-nuts g2 g2 on such bolts.

The connecting-bar G may be disconnected from the connection F (or F') by taking out the bolt G', or it can be disconnected at the other end thereof from the hinge E by taking out the bolt G therein and allowed to remain connected to the connection F (or F') in the folding of the bars b b', as hereinbefore described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

v1.v In a lace-curtain stretcher, side rails joined to end rails, such side rails comprising, on one side of the frame, bars hinged together by a hinge the plates whereof are pivotally secured together, with interlocking projections on the plates, and a cross-bar secured to one of the projections, and on the other side of the frame, bars joined. together by a connectingplate provided with openings therethrough, bolts passing through such opening and through the bars, nuts on the l bolts, and abolt passing through the central opening in the plate, through the cross-bar which is secured to the hinge on the other side rail, and between the ends of the side bars, with a nut on such bolt; substantially as described.

2. In a curtain-stretcher, side rails, one

` whereof comprises bars joined together by a hinge and the other, bars joined together by a connecting-plate; such hinge consisting of plates pivoted together, projections on such plates respectively, such projections interlocking when the hinge is open, and means for pivotally attaching a cross-bar to one of the projections of the hinge, and such conymeeting-plate consisting of a plate having openings therethrough, bolts having nuts thereon extending through the openings in the plate adjacent to thev ends thereof and through the bars to which the plate is attached, and a bolt extending through the opening in the center of the plate, and through between the ends of the bars forming the side rail, with a washer and av nut on such bolt, and a connecting cross-bar secured to the hinge by a pivot passing through the projection on one of the plates thereof and to the connecting-plate by the bolt which passes IOO through the central opening therein; substantially as described.
