srATES ATENT `JOHN n.. RAMSI-Immos EDMONTON, ALBERTA, CANADA-,41' Ai f CURTAIN-FASTENERLM" v j lBe it known that I, JOHN R.' RAMsHAw, subject of the King of Grreat` Britain, residingVv at Edmonton, in the Province of Alberta and Dominion lof Canada, have invented certain new and useful Improvements in Curtain-Fasteners, of which the following is a specification. Y

My invention relates to new and useful improvements in a curtain fastener and more particularly to a `device of this 'chara'cter adapted to be used on carriages and automobile curtains.

The primary the provision of a fastener which is simple and inexpensive in construction and adapted rto be connected to the curtain in such a manner that it may be operated by the occupant of the vehicle without alighting from the vehicle or extending his hand and arm to the outside of the curtain.

A further object isthe construction of the fastener with a spring catch whereby it will be securely held in position against accidental displacement.

Another Objectis the provision of means for connecting the fastener to the curtain fabric.

vWith these and other objects in view, my invention consists in the novel details of construction and the arrangement of parts which will be more fully understood from the following specification and drawings in which:

Figure l is a front view of the fastener.

Fig. 2 is a side view ofthe fastener.

Fig. 3 is a vertical section on the lines 3-3 of Fig. 1 looking in the direction of the arrow.

Fig. 4 is a transverse section on the line.

4.--4 of Fig. 3 looking in the direction of the arrow.

Fig. 5 is a transverse section on the line 5-5 of Fig. 2 looking in the direction of the arrow, and

Fig. 6 is a transverse section on the line 6-6 of Fig. 3 of the drawing.

In the drawings the numeral 1 indicates a stud or button provided with a threaded shank 2 and a notch 3. The threaded shank 2 is adapted to be engaged in the body of the vehicle at the desired points.

The curtain fabric is indicated at 4 and a plate 5 having a central Opening therein is received', upon the inner face of the fabric and is provided with two rows of circumobject of `the invention is y Specification-olf Letters Patent. y i Paeltd ull/Irtil'. 1919i:` f Application medina'rcn 19,1918. ysei-taint. 223,384..v

ferentially spaced openings; as morel parlticularlyillustratedin Fig. 6 of the-draw-l ings, for the purpose as' will be presently ing in the plate 5, vis connected to the oppo site side of the fabric 11 and is provided with prongs 8 adapted to pass through the outer row of openings'in the plate 5 and be bent to engage the opposite face of said plate 5. The fabric 4 held between the plates 5 and 7 is provided with a central openingadap'tf,

ed to register with the central openings in the plates referred to forvthe lpurpose as l will be presently described.

A housing 9 is adapted to be connected to the inner face of the plate 5 by means of prongs 10V which pass through the inner row of openings formed in said plate. The housing is vprovided with the flange 11 which engages the face of the plate 5 as `more particularly illustrated in Fig. 3 of the drawing. The housing 9 is provided with the slot 12 in the top thereof and asliding plate 13 passes through said slot so that the lower end will be received in the housing. This sliding plate 13 is provided, adjacent the lower end, with an elongated opening 14 and the upper end is curved as indicated at 15 to form a finger grip. `Springs 116, preferably of the shape illusrtrated in Fig. 4 of the drawing, are connected to the housing 9 and engage in notches 17 formed in the edges of the sliding plate 13. These springs 16 normally hold the sliding plates 13 in its lowermost position. Projections 18 are formed on the interior of the housing 9 and engage opposite edges of the sliding plate 13 and form a guide therefor. A similar projection 19 is formed beneath the projections 18, and intermediate thereof, and is Iadapted to be engaged by the lower end of the sliding plate 13 to limit the movement thereof.

Having fully described the detailed construction of my device it is thought that the advantages and mode of operation will be clearly understood. In curtain fasteners as now commonly constructed considerable dif thefhead or-l-studflsosthat" thevcurtain lWill*y Vso culty has been experienced in fastening or disengaging the curtain While the person is in the vehicle.-As ordinarilyconstrueted it is necessary for the person to reach around the curtain to get his hand on the"outside Y to fastenA or disconnect.

It is to overcome theserobje'ctions' that my invention is intended and I have provided ,a4 fastenerwhere-by the curtain may be easily fastened or dis- 'engagedgby Aabe;L persone Whilestill .in l the vehicle.- When the*curtain is fastened parts-:Will be infthefposition-s indicated- 1n lo/drawings soth-at.: the stud or head 1 Willlpassfithroughqthef central openings inthe :housing: I9, plate fabric 4C, and iplate 7 The :upper'fendfof theelongatedslot 14 inv be-gsecurely-connectedto the vehicle body.
