Application filed November-17,1906. Serial No. 843.919.

To all whom it may concern.-

Be it known that I, EMIL SonAFrNna, a citizen of the United States, residing at Wimbledon, in the county of Barnes and State of North Dakota, have invented a new and use' ful ConveyersApron, of which the following is a specification.

- This invention relates tononveyer-aprons, and 'is particularly designed for use upon binders and other agricultural machines.

Heretofore considerable difficulty has been experienced with the aprons of machines of this character, because the straw often becomes' wedged beneath the slats on the apron and. breaks them and is also sometimes carried around by the apron, thereby seriously interfering with the operation of the machine.

The-object of the present invention is to provide an'apron which will 'obvi'ate'these disadvantages.

, With these and other objects in view the invention consists of certain novel features of construction and combinations of-parts,

which will behereinafter more fully described, and pointed out in the claims.

Inthe accompanying drawings is shown the preferrefgiijorm of the invention.

In said ings, Figure 1 is a view showinga portion of a conveyer before the same has been folded over the slats thereof. Fig. 2 is a plan view of a portion of the finished conveyer, the fabric being spread apart at one corner; and Fig. 3 is a longitudinal sec tion through a portion of the conveyor.

Referring to the figures byv characters of reference, 1 IS a strip of canvas or other su1table material of double width, and secured upon this strip and extending, preferably, about half-way across thesame are slats 2,

said slats being fastened in place byrivets 3 or in any other preferred manner.

That portion of the strip 1 extending, beyond the ends of the slats is folded thereover to form an upper strip 4, and this upper strip rests against the rear faces of the slats and is then sewed, as at 6, so as to present a smooth shoulder extending at right angles from the apron. Those portions of the upper strip 4 .in front of the slats are sewed down at points removed from the faces of the slats, as shown at 7, so as to produce inclined portions 8; This upper strip 4 is preferably left loose to a certain extent, so'that when the apron passes around its sup 'orting-rollers there will be no danger o the seamssurfaces 8 will prevent the apron from carry ing the straw around with it, and thereby interfere with the o aeration of the machine. Straps 10 are pre erably secured iongitudi-;' nally under one end of the strip 1', and buckles" 11 are secured adjacent the other end thereof.

A large number of sections such as described canthereforebe fastened together by means of these buckles and stra .s, so as to form a continuous apron of any esired proportions.

Although the apron-section has been described and shown as formed in a single width of fabric, it is to be understood that, if preferred, the top and bottom strips may be separate and can afterward be secured together along their front edges.

By the term slat used by me in refers ence to the part 2 it is to be understood that I do not mean to restrict myself. to a strip 2' of anyparticular form or material, as said strip can be made of wood, leather, rope, or,

in fact, anything, whether flexibleor rigid,

- with which the proper resultscanbe obtained.

The preferred form of the invention has been set forth. in the foregoing description; but I do not. limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and. I therefore reserve the ri ht to make, such changes as fairlv fall within the scope, of the claims.

What is claimed is- 4, p
