CONVEYER-APRON.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed September 24, 1913. Serial No. 791,600.

To all zo/7mm t may concern.'

Re it known that l, WERNER S'rnnnn, a citizen of the United States, residing at Cedar Vale, in the county of Chautauqua and State of Kansas, have invented new and useful Improvements in Conveyeirprons, of which the followingis a specification.

This invention relates to conveyer aprons, the object of the invention being to| produce an apron of the class described embodying a novel construction of slats o-r flights so mounted upon and related to the body of the apron as to render it impossible for any matter to get in or under and around the slats so as to interfere with the operation thereof.

.ik further object of the invention is to pro` vide in connection with a flexible apron, a special form of slat or flight which will obtain a positive hold on the body of the apron and avoid any `possibility of the apron and slats becoming disconnected from each other, also overcoming any liability of the slat splitting or breaking during the operation of the apron, and also permitting the apron to pass easily around small rollers without increasing` the friction and load on the propelling mechanism.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will hereinafter be more fully described, illustrated and claimed.

ln the accompanying drawings :HF igure l is a perspective view of a section of a conveyer apron embodying the present invention. Fig. 2 a cross section on an enlarged scale through one of the slats showing also a portion of the apron body and the connecting means. Fig. 3 is a view similar to Fig. 2 showing the manner of anchoring one of the conveyer end straps.

Referring now to the drawings l designates the apron proper which is ordinarily formed of canvas and which, of course, may be of any desired length and Width. Secured to one of the faces of the apron and arranged at suitable intervals, are cross slats or flights designated generally by the reference character A, each of said slats embodying a sheet metal sheath 2 the opposite longitudinal edges of which are rolled inwardly to forni core retaining and covering rolls or hollow beads 3. ln each of the beads or rolls 3 is inserted a core rod 4 preferably of wood round in cross section and of a length ap` proximately equal to the length of the complete slat or Hight. It will, of course, be understood that material other t-han wood may he used in making up the core rods 4. .fil portion or bight of the apron l is inserted between the rolls 3 of the sheath in the manner illustrated clearly in Figs. 2 and 3 and a key rod 5 is inserted in said bight and as the inserted portion of the apron passes around said key rod 5 it is impossible for such inserted portion of the apron to be withdrawn from the slat as a. whole by reason of the fact that the key 5 surrounded by a portieri of the apron, is prevented from passing between the rolls 3 in which the core rods 4 are contained. Rivets or other fasteners are inserted transversely through the rolls 3 and core rods 4 in parallel relation to the general direction of the apron l, said fasteners 6 preventing any separation between the parts which would release the key rod In connecting the end straps 7 to the apron, the inner ends of said straps are carried around the key rod 5 and fastened together just under said key rod as shown in Fig. 3. The fastening of the straps 7 is made still more secure by reason of the fact that one of the fasteners 6 also passes through the looped inner end of the strap after the latter has been passed around the key rod 5. This makes it impossible for the strap to be pulled away from the apron. The straps 7 may be provided with the usual buckles and holes or other complemental fastening of the apron are secured together.

8 designates metal end caps with which each slat or flight is provided after the rods 4 and 5 have been inserted in the slat and all of the part-s brought into their nal posit-ions. These end caps also serve to prevent any spreading action on the part of the rolls 3 and core rods 4.

What I claim is:

l. A conveyor apron comprising a ieXible sheet or body, and a series of slats secured at intervals to one face thereof, each of said slats comprising a sheet metal sheath having the opposite longitudinal margins thereof turned inwardly to form tubular rolls, a portion of the body of the apron being inserted between said rolls, a key rod inserted through the bight of the apron body within said sheath and behind said rolls, and core rods inserted in said rolls.

devices whereby the ends 2. A conveyer apron comprising a lieXible sheet or body, and a series of slats secured at intervals to one face thereof, each of said slats comprising a sheet metal sheath having the opposite longitudinal margins thereof turned inwardly to forni tubular rolls, a portion of the body of the apron being inserted between said rolls, a key rod inserted through the bight of the apron body within said sheath and behind said rolls7 core rods inserted in said rolls, and fastener passing through said rolls and core rods.

3. A conveyer apron comprising a flexible sheet or body, and a series of slats secured at intervals to one face thereof, each of said slats comprising a sheet metal sheath having the opposite longitudinal margins thereof turned inwardly to forni tubular rolls, a portion of the body of the apron being inserted between said rolls, a key rod inserted through the bight of the apron body within said sheath and behind said rolls, and an apron securing strap having one end thereof inserted between said rolls and looped around said key rod.

ln testimony whereof I aiiix my signature in presence of two witnesses.
