UNITED STATES PATE NT `OFFICE JO'HN E. SCHRODEB, OF HARTFORD, CONNECTICUT, ASSIGNOR T0 HARTFORD-EMPIRE COMPANY, 0F HARTFORD, CONNECTICUT, A. COBPURATION 0F DELAWARE CONVEYER l Application led J'une 28,

My invention relates to conveyers, and more particularly to those of the belt type, made from woven wire, as shown for instance'in Patent No. 1,583,046 issued May 4,. 1926, to H. W. Ingle.

More specifically stated, my invention comprises the provision of cleats or stop members on a conveyer belt of woven wire or other material, so that the ware will not slide on the conveyer when being moved in an inclined plane. A Y i One object of my invention is to provide a convenient and effective means for attaching a cleat to a mesh-like conveyer belt.

Another object of my invention is to provide means for supporting a cleat in a conveyer belt without the employment of members other than those forming a portion of the belt proper.

Still another object of my invention is to simplify and improve generally the structure of conveyer devices of the type referred to.

Some of the forms which my invention may take are shown in drawings, wherein Figure 1 is a longitudinal sectional view of aportion of a conveyer system embodying my invention;

Figure 2 is a plan view of a portion of the conveyer belt of Fig. 1, on an enlarged scale;

Fig. 3 is an elevational sectional view of a portion of the apparatus of Fig. 2;

Fig. 4 is a view similar to Fig. 2, but showing a modiiied arrangement for holding the cleats in position on the belt, and

Fig. 5 is an elevational sectional view of a portion of the structure of Fig. 4.

Referring to Figs. 1 to 3, I show a conveyer belt 6 of woven wire or of other mesh-like form that may be employed to convey glassware or the like from a lower plane 7 to a higher plane 8, or vice versa. The belt passes around guide rollers or

sheaves

9 and 10 and a driving roll or pulley 11 which is driven from any suitable source of power (not shown).

As the ware is moved upon the' conveyer belt, it is prevented from sliding down the incline by cleats 12, which are secured to the accompanyii 1927. Serial No. 202,037.

the belt 6 at suitable intervals. The securing means consists of `a spiral like strand 13 that passes over the cleat 12 and beneath one of the strands 14 `of the mesh 6. While the cleat-holding strand 13 could be passed into interlocking relation with a plurality of the strands of the mesh 6, I prefer to have itv engage only one of the strands such as 14, so that there will be no interference by the cleat and its holding strand with the flexing of the belt 6, particularly when it passes around the rollers or sheaves, thus avoiding distortion of the mesh body.

In Figs. 4 and 5, I show a modification wherein the belt or mesh 6a is so distorted as to permit attachment of a cleat or stop member 12a without the employment of holding means other than a portion of the belt itself. To eii'ect this object, I draw

strands

15 and 16 of the belt 6 together, so that an intermediate strand 17 can be deflected upwardly to permit insertion of the cleat 12a between the upper bends of such intermediate strand and adjacent portions of the

strands

15 and 16. If the angularly extending portions of the strand 17 were of considerably greater length than as shown in the drawings, and the cleat 12a of suiciently small diameter, the cleat would, of course,

not be vertically supported directly by ad-l jacent bends of the

strands

15 and 16, but would simply lie between the upper and lower angularly-extending portions of the strand 17, and in that event there would be less interference with bending of the belt 6a when passing around the guide rollers.

It will be apparent that my invention is not limited to belts of the woven wire type, but can be employed in connection with belts of various other types, and particularly those of mesh-like form.

I claim as my invention 1. Conveyer belt structure comprising a mesh-like body composed of members having jointed interlocking connection with one another, a cleat, and means for securing the cleat to'said body between two adjacent lines of said interlocking engagement, to permit freedom of lexure by the said body.

2. A conveyer belt comprising a, plurality of helical Wires disposed transversely of said belt and loosely interlinking to permit flexure of said belt, a cleat also disposed transversely of said belt, and a helical wire interlinking with one of said first named helical Wires independently of said flexible interlinkages and encircling said cleat for holding it in place.

3. A spiral conveyer belt comprising a fabric formed of successive interlaced spiral cross Wires extending from side to side of said belt, spaced supplementary spiral Wires interlaced with certain spiral cross Wires and projecting outward from one face of said fabric, and cross rods extending through said supplementary spiral Wires to hold the said Wires in outwardly projecting position, said cross rods being held from longitudinal displacement in said spiral Wires.

4. A spiral conveyer belt comprising a fabric formed of successive interlaced spiral cross Wires extending from side to side of said belt, spaced supplementary spiral Wires interlaced With certain of said spiral cross Wires and projecting outward from one face of said fabric, and cross rods extending through said supplementary spiral Wires to hold the said Wires in outwardly projecting position, the spiral of said supplementary Wires being flattened in cross section.

5. A spiral conveyer belt comprising a fabric formed of successive interlaced spiral cross Wires extending from side to side of said belt, spaced supplementary spiral Wire interlaced with certain spiral cross Wires and projecting outwardfrom one face of said fabric, and cross rods extending through said supplementary spiral Wires to hold the said wires in outwardly projecting position, the spiral of said cross Wires and of said supplementary Wires being lattened in section, and said cross rods being held from longitudinal displacement in said supplementary cross Wires.

6. A spiral conveyer belt comprising a fabric formed of successive interlaced spiral cross Wires extending from side to side of said belt, and spaced cross bars mounted on said belt and hingably connected thereto at closely adjacent point-s through the Width of said belt said cross bars extending substantially parallel to said spiral cross Wires and projecting beyond a surface of said belt to form,

transverse abutments thereon.
