Be it known that ll, lHoMAs ALLsor, of Philadelphia -in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gonveyers for lDriers, whereof the following is aspeciiication, reference being had to the accompanying drawings.

The invention relates more particularly to endless conveyers which are used for drying fabrics or other materials which are of the flexible nat-ure.

An' object of the invention is to provide a conveyer inpwhich the apron is connected tothe supporting structure by a novel and eX-4 tremely simple means.

ln the drawings which show by way of illustration one embodiment of the invention, Figure I, is a plan view showing a section of an apron and the supporting devices therefor, which apron embodies my improvements. Fig. Il, is an end view of'a section of the same. Fig. lll, is a section on v the line Ill, UI, of Fig. I. FigfIV, is an enlargedl view showing one of the links or membersv used in the forming of my improved apron. Fig. V, is a section through one of the cross Abars as indicated at V, rif in Fig. l.

As herein shown, the apron is formed of a plurality of intereng'aging spirally wound transversely extending members, which are. preferably slightly flattened so as togive a substantially smooth upper and lower surface to the apron.

Referring more in detail to the drawings, the conveyer consists ofa plurality of crosspieces 1, which as herein shown, are secured I to links 2, which form one element of a'tra-in of interengaging links 3. These links 2, and 3, areoonstructed in the usual manner, so as to run over sprocket wheels, and thus provide an endless carrier. The apron on which the material to be dried is laid consists of a plurality of members 4. Asherein shown, each of these members is 4formed of a strand ofwire, which is spiral in shape, and' slightly flattened, so as to form upper members 5, and lower members 6. The adjacent spirally formed members throughout the intermediate v members of the belt,4 are interengaged as clearly shown in Figs. ll, and Ill. The member at one end is bent into hook form, and is interlocked with the adjacent member at the same end. These interengaged transversely extending spiral-members make up the apron on which the material rests. The apron extends over eac-h cross-piece and the ends'ot the apron or sections of the apron are secured by locking bars 7, threaded through the meshes at the adjacent edges whereby there is provided a practicallycontinuous apron surface. The locking bars?, serve the further purpose of securing the apron at intervals to the cross-pieces.

While I prefer to make my apron of members which are spirally wound, it will be obvious that said members may V,be otherwise formed, provided that theyl areconstructed s o asto give a substantial thickness to the apron, and also provide an air space between the upper and lower surfaces of the apron.

From the above description, it will be apparent that I have provided a. conveyer wherein the apron is entirely Jfree from anyv `pivot or hinge connect-ion witheach crosspiece, as the apron extends over the crosspieces, Vand merely rests thereon, and the only pivoting as the apron; turns with the Alinks about the sprocket, is between the adjacent links or members of the apron.

Cross pieces 1, are made of ironpipe carried on projectionsformed on the sides of certain of the links and secured thereto by cotter pins 10, whereby the link chains are properly spaced and the cross pieces prevented from turning. Where the ends of the apron are interlinked by the locking bars' 7,

eye bolts 1l, with short Shanks are fastened into the cross-piece and the locking bars pass through the eye bolts. These eye bolts ,may pass entirely through the crosspieces as Vshown in Fig. V, in order to lessen strain uponthe threads .ofthe eye bolts and to.' secure better wearing qualities for the conveyer, but the end eye bolts where the projections ,of the links enter int-o the hollow ends of the cross-pieces, areprovided with short Shanks screwed into the top of theV crossepiece, as shown in Fig. IH.

Having thus described my invention, I .claimt A conveyei` including parallel eniless ln testimony whereof, I have hereunto cha-ins, cross pieces spacing the seine,fanv signed my name at Philadelphia, Pennsyl- 10 pron resting on laid gross pieces, a lckn" venia, this 26th day of J une, 1912.
