Specification of Letters Patent.

Application led November 9, 1910. Serial No. 591,400. i'

To all whom it may cof/wem:

Be it known that I, ALBERT W. 'I`rroi rr son, a citizen of the United States, residing at Manchester, in the'county of Hillsboro and State of New Hampshire. have invented a new and useful Tire-Cloth Apron, of which the following is a specification.

This invention relates to an apron for use in conveying material, and is particularly designed for use in vdriers and washers for wool and similar fibrous materials, yarn conditioningmachines, and the like, but is capable of general use.

The principal objects of the invention are to provide simple and convenient means whereby when the wire cloth of the conveyer breaks, a small section of it can-coii'veniently be removed and replaced without interfering with the rest of the apron; also to provide -a construction in which the removal of the section can be accomplished in a very expeditious manne-r and in which it can be replaced also in a very short time; and to provide an improved form of connection between the several sections of wire cloth capable of being readily supported on transverse slats between the chains.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompany-l ing drawings7 in which* Figure 1 is a plan ofal portion of a'woolV drier showing an endless apron constructed 1' in accordance with this invention; Fig. 2 is al plan of a Yfew sections of their ron and chain on enlarged scale; Fig. 3 is a vertical .sectional view of a portion of the samefn the line 3-3 of Fig. 2; and Fig. 4 is a plan of a modification. P

The invention is shown as applied as usual to a double chain 10 passing over sprocket .wheels 11 between which sprocket wheels `are shown drums 12 for supporting the wire cloth of the apron while the chains are passing over the sprocket wheels. The chains are connected at intervals by transverse .slats 14, these slats being riveted to wprojections 15 on certain of the links so as to form rigid connections between the chains.

ures, the wire cloth 16 is of the spiral mesh variety. Each section between twov slats constitutes acomplete element in itself and the edges are brought up close to the slats on opposite sides of the wire cloth. Around each slat is wound a spiral wire 17 of an oval form in cross section, and the oval links are united with the spiral mesh wire cloth on both Sides by means of transverse wires 18 which extend through the edge links of the wire cloth, and also through ,the links of the wire v16. The ends of these wires 17 are turned over to unite them firmly with thev last links. It has been found in practice that wire mesh aprons when passing over the drum tend to creep to one side and this is particularly true of the spiralmesh variety. lFor overcoming this feature, each sectioniof wire mesh is located oppositely to the next one before and behind it so that any tendency to creep due to one section is counteracted by the tendency to creep in the vopposite direction of the next one.

When it is necessary to remove one of these `sections for repairs it is only necessary to straighten the ends of the wires 18 of that section and remove them by a motion parallel with the slats. This instantly frees that section of wire'niesh, and a new or re- .,paired section can be put in in a very short which the wire cloth 2O is of the square mesh variety. In. this Lease the selvage is Patented Mar. 21. 1911.

straightened out and the coils 17 introduced between the loops thereof and fastened by wireslS as before described. In this case the coils 17 are preferably galvanized to the transverse slats so that they are permanently fixed in position.

While I have illustrated and described only two forms of the invention and shown it Las applied particularly to a wool drier, I am aware that it can bevmanufactured in many other forms and applied to many other types of machines without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but

What I do claim is 1. The combination with a pairof chains, of transverse slats `connecting them, a coil of wire on each Slat, wire cloth sections beiii-M' tween the slats, and meansfor removably attaching the wire cloth sections to the coils.

2. In a conveyer apron, the combination of a plurality offparallel transverse slats, a continuous flattened coil of wire around each of the slatsprojecting at the front and rear, sections of wire cloth between each two adjacent slats, 'and means for removably connecting the coils with the wire cloth. ,x

3. In a conveyer apron, the combination of transverse slats, sections of wire cloth between each two adjacent slats, and means removable parallel with the slats for connecting the wire cloth with the slats without removing the slats.

4. As an article of manufacture, a conveyer apron, comprising transverse slats, 1.

flattened coil of wire on each slat, projectingv at the front and rear, a wire clot-h section between each two adjacent slats, and a wire parallel with t-he slats for connecting each edge of each section with the wire coil.

5. As an article of manufacture, an endless apron comprisingl transverse slats, a coil ot' wire made up of a number of convolutions surrounding each slat, said coils of wire being flattened above and below and projecting beyond the slats at the sides, spiral mesh wire cloth sections between each two adjacent slats, and transverse wires parallel with the slats, one on each side of each slat connecting the coils thereon with the coils of the wire mesh, said wires being bent at the ends to hold them in position.

6. As an article of manufacture, an apron of the class described, comprising transverse slats, a coil of wire extending around each slat, wire cloth removably connectedA at each edge with the coils, and wires parallel with the slats for holding the wire "cloth thereto.

7. As an article of manufacture, an apron of the class described, comprising transverse slats, a coil ofwire extending 'around each slat, and wire cloth sections between each two adjacent slats removably connected at each edge with the coils.

8. In an apron of the class described, the combination with a pair of supporting chains, transverse slats connecting said chains, sectionsof wire cloth between the slats, holding means permanently mounted on each slate, and removable means for connecting said holding means with the wire cloth.
