vagano Patented Feb. 3, 1931 UNITED STATES *PATENT OFFICE I FRANCIS N. WOODHAN, OF CLINTON` MASSACHUSETTS, ASSIGNOR T0 WICKWIEE SPENCER STEEL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE CONVEYEB BELT WITH BEEN FORCED RAISED EDGES Application led Hatch 18, 1829. Serial 110.347,749.
two edges of'such a" belt, which raised edge portions are of an improved construction by which greater safety andincreased durability 10' are attained.
A further object is to provide a construction by which supplementary contact or wearing portions are provided for the belt, greatly prolonging the life thereof under certain 1.5 operating conditions. p
My improved construction also stifl'ens the belt so that it is better adapted to resist sagging between its supports, while at the same time the necessary flexibility of the belt is maintained. p
My invention further relates to arrangements and combinations of parts which will be hereinafter described and morey particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawings in which Fig. 1 isa plan view of a portion of my improved belt;
Fig. 2l isa partial end elevation thereof, looking in the direction of the arrow 2 in Fig. l; i'
n Fig. 3 is a bottom view of the edge portion, looking in the direction of the arrow 3 in Fig. 2; and i Figs. 4, 5 and 6 are views similar to Fig. 2 but showing certain modifications.
Referring particularl to Figs. 1, 2 and 3, I have shown a portion o a wire conveyer belt formed of a plurality of spiral wire members 10, each member being interlaced with its The spiral wires 10- and spreader rods 12,' f after assembly, have their end portions bent upward, as indicated in Fig. 2, to form edge! ange portions 20, adapted to retain the transported material upon the belt and to prevent ateral displacement thereof.
The ends of the wires .10 are then bent reversely downward to form outer or double fold portions 22, but the spreader rods 12 preferably do not extend into these outer or double fold portions.
While the belt is in its flat condition, the ends 24 of themembers 10 are preferably twisted or looped together, as indicated in Fig. 3, to provide a rough form of selvage for the fabric. After the edges are double-folded\ to the form shown in Fig. 2, these end portions 24 are positioned at the extreme lower edges of the outer folds 22, where any roughness or irregularity thereof will be harmless. All of thespiral wires are'continuous around the U-s aped reverse folds of the fabric and there is nothing'expos'ed which can injure the operator.
These double folded edges greatly stifl'en the belt against sagging between supports but this stiifening is accomplished without destroying the desired flexibility'ofthe belt.
It will also be noted that the iexing of the` belt tends to press the looped end portions 24 closer together, rather than tending to separate these end portions, as might be the case with up-standing fianges of single thick-` i ness. i In Fig. 4 I have indicated a slight modi- 30 are disposed inside of the flangesv 32, rather than outside as indicated in Fig. 2. This construction presents smoother outer sul-- faces and-may lbe of advantage in special circumstances.
Tn Fig. 5 Ivhave indicated a further modification in which the outer double folds 40 are extended downward and under the main body ofthe belt, as indi-cated at 42, thus pr`o-l viding supplemental wearing surfaces which stallations where the belt is dragged along a stationary sup orting surface 44 such as the hearth of a urnace.
Aication 1n which the double or second folds Igreatly prolong the life of the belt, in in- In the modification shown in Fi 6, a belt formed as indicated in Fig. 2 1s used in an inverted position, and shoes 50 are clamped on the downwardly extending double folded edges, providing wearing surfaces better adapted to resist hard Wear than the coils of the spiral wire members. Obviously the shoes 50 may be removed and renewed, :tthus indefinitely prolonging the life of the elt.
Having described several forms of my invention, the advantages thereof will be readily apparent. When the belt runs between edge guidesv 60, as indicated in F ig. 2, the outer fold 22 takes the entire wear against the guide and even when this outer fold is entirely worn away, the up-standing edge portion 20 still remains in condition for continued use.
lt is also found that a belt having my im! proved double re-enforced edges is so strengthened thereby that it may be run in vertical edge position instead of in the usual horizontal position. The double folded edge is Well adapted to sustain the weight and wear on the belt when running in such vertical edge position, .which is sometimes desir- 3. The combination in a wire conveyer belt as set forth in claim l, in which said reversely folded edge portions are disposed outside of said flange portions to provide outer Wearing surfaces therefor.
4. The' combination in a Wire conveyer belt as set forth in claim' l, in which said reversely folded portions are disposed outside of said flanged portions and extend under the sides of the bbdy portion to provide supplemental wearing surfaces therefor.
5. The combination in a wire conveyer belt as set forth in claim l, in which the ends of the spiral members are looped together at the edges of said reversely folded portions of said belt.
6. The combination in a wire conveyer belt as set forth in claim 1, in which wearing shoes are secured about the folded edges of said double anges.
in testimony whereof I have hereunto affixed my signature.

While the use of the spreader rods 12 is desirable, many of the advantages of my invention can be utilized when the spreader rods are omitted. These rods serve the particular function of preventing lateral shrinkage of the belt when under severe service conditions.
Having thus described my invention and the advantages thereof, do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what claimy is p l. A wire conveyer belt comprising interlaced spiral wire members extending transversely of the belt, the end portions of said spiral members being bent at an abrupt angle to the body of the belt to form longitudi-` nally extended edge flanges projecting outwardly from the body of the belt and extending away from said body portion at a substantial angle and the extreme edge portions of said flanges being reversely folded to pro-
