Although the fasteners may be secured to the Referringtothe drawings: canopy covers in any desired manner, I prefer to secure the fasteners 2| to the folds I3 and I4 in such a manner that the tongues 25 of the fasteners on one of said folds are on the opposite side of the tongues 25 of the fasteners on the other of said folds. In other words, either in the position shown in Figs. 1 and 2, or in a position in which the fasteners 2| are secured to the front fold I4 in the manner in which the fasteners are secured to the rear fold I3 in said figures, and in which the fasteners 2| are secured to the rear fold I 3 in the manner in which I the fasteners are secured to the front fold I4. in said figures.

As an instance of this arrangement, the fasteners 2| are secured on the rear fold t3 insuch a manner that the tongues 25 are on the front side of the fold I3, that is, in the manner shown In the modification of my invention shown in Fig. 6, I omit the backing plate 26. In those instances, the plates 22 are secured to the de pending folds I3 and I4 by forcing the prongs 23 through the fabric and then forcing the prongs 23 over against the fabric. However, in order to provide a sturdier construction, in order to prevent the prongs 23 from tearing the folds I3 and I4, and for appearance purposes, I prefer to use the construction shown in Figs. 1 to 5 inclusive.

From the foregoing description taken in connection with the accompanying drawings, the

- 1, uses, advantages, and operation of my invention in Figs. 3 and 5. After the attaching plate 22" is positioned on the front side of the fold I3 and the backing plate'26 is positioned on the back side of the fold I3, said parts are secured together by forcing the prongs 23 through the fold I3, and the slots 21, and then forcing the prongs 23 over against the backing plate 26 as shown in Fig. 5. In this arrangement, the fasteners 21 are secured on the front fold it in such a manner that the tongues 25 are on the rear side of the fold I4, that is, in the manner shown in- Fig. 4. After the attaching plate 22 is positioned on the rear side of the fold l4 and the backing plate 26 is positioned on the front side of the fold I4, said parts are secured together by forcing the prongs 23 through the fold l4 and the slots 21, and then forcing the prongs 23 over against the backing plate 26.

Although I prefer to provide each of the depending folds i'3. and I4 with four fasteners 2i, obviously, the depending folds may be provided with any desired number of fasteners, depending upon the length of the canopy and other factors. The fasteners ZI are preferably secured to the canopy, cover at the factory.

After the canopy frame members It and l I are completely assembled, the canopy cover i2 may be easily and readily secured to said members by merely pushing the fasteners 2 I on said frame members from the bottom edges of said members. Obviously, if desired, the canopy cover I2 may be secured to the angle iron members [0 and H before the canopy frame is completely assembled.

It will be seen that the fasteners 2| are slidable on the frame members It] and II from one position to another, and therefore the position of the canopy cover I2 with respect to said members may be easily adjusted to compensate for shrinkage or expansion of the canopy fabric.

In instances in which the front and rear canopy frame members Ill and I! are composed in part of straight vertical members, the fasteners 2i may be secured to the folds I3 and I4 in such a manner that the tongues 25 project from the upper portion of the attaching plates 22. In such instances, the fasteners 2'I are adapted to be pushed on the frame members I0 and II from the upper edges of said member.

m Number will be readily understood by those skilled in the art to which-the invention appertains. While I have described two embodiments of my inven- "tionjI desire to have it understood that the forms shown are merely illustrative and that the invention is not to be limited to the details disclosed herein, but is to be accorded the full scope of the appended clainr I claim: r

A fastener for attaching a canvas canopy to a-frame member, com-prising: a rectangular backing plate having a pair of longitudinally aligned, spaced rectangular slots therein, the longer edges of which extend in parallel relationship to the longer edges of said backing plate, a complemen-taryrectangular attaching plate having a pairof pointed prongs integral therewith and extending laterally from the plane thereof, both ofsaid prongs initially lying in a plane which is; generally normal to the plane of said attaching plate and parallel to the longer edges thereof, said prongs being positioned to be received in said slots in said backing-plate and to be folded against said backing plate to retain said plates in assembled relationship, and a tongue integral with said attaching plate", said tongue having a shankportion extending from one of the longer edges of said attaching plate in a direction opposite to the direction of said prongs and in generally parallel relationship to the plane in which said prongs initially lie, and said tongue terminating in an end portion which is laterally spaced from and generally parallel to said attaching plate, whereby application of force to said" tongue'in a direction at a right angle to the lower edges of said plates will result in distribution of the stresses applied to canvas positioned between said plates and pierced by said prongs.
