OUR'rAIN-STRETOHER.

e Vine Grove, inthe county of Hardin and State ofy Kentucky, have invented `certain new and useful Improvements in Curtain-y Stretchers.

ofwhich the following is a specification. v v f This-invention relates tol curtain jstretcheis, and has for its primaryl object topprovide a'simplied and improved device of this character which embodies means where# by curtains of various lengths and widths may be easily and quickly arrangednithiii, stretched and detached from the device', and

which v further embodies means for -adequately stretching the curtain without danger of, tearing the same.

A? further object of the yinvention `is to provide a curtain stretcher of this character` which is of simple andinexpensive construc-V which is positive in operation and Which may be takenapart and folded so as to occupybut a smallamount of space when not in use.

Vith these objects in view, togetherwith 4others which will appear as the description proceeds, .the invention residesfin'ithe novel formation, combination andarrangement of parts, all as `will be describedmore fully hereinafter, illustrated inthe drawings,.land particularly pointed out in the. claims.

The invention will ybe best understood with reference to the accompanyingdrawing, wherein Figure 1v isv a-top plan view, parts broken away,` of a curtain stretcher, constructedin accordance. with my invention;

Fig. 7 is-a detail perspective -viewfof one of the stretcher bar holding plates. Referring now more particularlyto the drawings, 8 .indicates a pair of main bars, each of whichis broken at a suitable pointl in its length and hinged as at 9 to permitof the saniej folding upon ;-the mse1ves. Slidably arranged upon each of the main bars 8 1 is a pair of sleeves 10, the latterI snuglyinclosing the main bars and beingheld in their diii'erentpositions of adjustment by the sety screws `11. Formed with each of the sliding' sleeves 10 and ina plane :slightly above the same isa loop, portion 12, the ,opening of which -is disposed atrigh-t angles to that-of f the sleeve portion to which it is attached. A guide flange 13 projectsupwardlylwfrom the sleeve `10 vandis disposed in alinement direction as with and in ,the same` general one edge of the loopportion 12. f

* Slidably arranged at their ends 4within the l alined loop portions 12, uponthelo-pposing main barsS aretransverse frame bjars14.

Set screws 15, are threaded` through` the. loop members '12 and areadaptedto -impingeA the frame bars' arranged therein to Ahcildtlie sil-1.1.16v in'various positions vof .adjustment Thel frame ibars 14 andthe main :bars 8 may be' graduated as shown, whereby the width and length required for the stretchingof a certain fabric may be quickly 4and, easily determined.- Byj loosening ythe .set

screws 11 and 15,;it is` obvious that the frame,

consisting of. the main andframe bars 8 and 14may be very easily. andquickly expanded or contracted. When larranged the desired.V

distance apart, the set screws may. betightened tomaintain the bars in iixed position.

upon themain or longitudinalbars 8. The

tudinal edge, the said tongue engaging beneath and supporting the stretcher bar 16.`

The stretcher bars supportedby the vend `orframe bars 14. are ofsubstantially the same. dimensionas the latter and. are held spacedfrom the iii-' ner. longitudinal vedges thereof by' bracket members 17'.v .The-stretcherbars lie in the same plane with the frame bars 14, and r rest l100 bracket 17A compriSeS a. metallic `1.01am;llavf ingle downwardly andenvardlv extending tongue 18.projeetiiig from lits 4inner longif from the inner longitudinal edges of the plate 17 and engage over the top face of the adjacent stretcher bar. Screws or tacks may be driven through suitable openings 20 in the tongue 18 to rmly secure the stretcher bar thereto.

The stretcher bars 16 carried by the longitudinal or main bars are secured upon the upper faces thereof, and lie i'n the same horizontal plane with the stretcher bars carried by the end lor frame members 14. The longitudinally disposed stretcher bars are formed in sections as shown, to permit of the device being readily folded. It will be understood that the extremities of the sectional stretcher bars will abut when the main Yor longitudinal bars are extended or in operative position.

Each of the stretcher bars above described is equipped with means for securing the edge of a curtain or other fabric thereto, and are rabbeted or cut away upontheir inner edges and throughout the extent thereof as indicated at 21. The base portions of these cut outs are grooved orchanneled as at 22, the construction providing a 'shallow upwardly extending rib 23 at the outer part of Vthe rabbeted portion and 'extending Y throughout the length of the stretcher bar.

Projecting upwardly from the channels in the said stretcher bars and 'inwardly 'from the ribs 23 thereof are 'pegs or pins 24, theV latter being adapted toengage through the i stretcher bars to which they are applied, and

edge of a, curtain fabric.

Associated with each of the stretcher bars is a clamp member 25'. The clamp members in the present instance comprise'elongated plates substantially coextensive with the project at one longitudinal edge outwardly over the rabbetedfor cut away portion 21. The extended edges ofthe plates are bent downwardly to provide foot portions 27,

the latter being bent inwardlyatftheir lowermost ends as at 2S to present a substantially rounded edge. These rounded edges terminatein close proximity to the bottoms of the Y channels formed' at the base of the cut out,

portions, and are disposedv inwardly from the pegs 24.- As a means for securing the clamps 25 upon their respective clamp bars,

bolts 29 are extended upwardly through the A clamp bars and through laterally disposed elongated slots 30 inthe clamp members. The upper threaded extremities of the bolts 29 may be equipped with wing nuts 31, whereby the clamps may be adjusted toward and away from their clamp bars and also to permit ofadjusting the clamps laterally of the said bars. The bolts 29 extend through Vthe longitudinalor main barsS and thence through the clamp bars and clamps, where# Copies of this-patent may be' obtained for by the said bolts bind the clamp bars to the longitudinal bars, and the clamps to the clamp bars.

In operation, the lateral and longitudinal bars of the frame are adjusted through their sliding sleeves and loop portions to the size proper for the accommodation of the fabric to be stretched. The set screws are then tightened, whereupon the wing nuts 31. are

loosened so that the edges of the fabric may be engaged over the pegs housed beneath the depending foot portions of the clamps. After the fabric is thus arranged within the frame, the wing nuts are tightened, whereupon the clamps are forced downwardly until their rounded smooth portions engage with the fabric, and thus bind the edges of the saine into the channel at the bottom of the rabbeted portion. If desired, the fabric thus stretched may be further tensioned by moving the stretcher bars outwardly or inwardly, and it will be apparent that such movements or the contraction of the fabric will be borne by the elongated foot portions of the clamps. Tearing out of the fabric edges is thus obviated.

While the above is a description of the preferred embodiment of the invention, it is obvious that various changes in the minorA details of construction and arrangement of parts may be resorted to without departing from the spirit of the invention or exceeding' the scope of the claims.V Vhat is claimed is:

1. In a device of the class described, a plu-V adjustably secured to each other, stretcherv bars secured to said lateral bars, a platesecured to each of said frame bars, a ltongue projecting downwardly and forwardly from each plate, arms projecting from the ends of each plate and lying above said tongue, clamp bars carried by said plates and being supported between said arms and tongues, and means for securing fabrics to said clamping bars, substantially as described.

In testimony whereof I afli'X my signaturein presence of two witnesses.
