Application filed February 28, 1927. Serial Ne, 171339.

In laundries the manglers are required to handle dill'erent classes ot' articles some of which are heavier in weight and require reironing to properly dry the same. The

lnanglers are set to run at a speed sufiicient to properly iron the average run of pieces, but when heavler pieces'put through a mangler are deposited on the receiving table they mayreadily be selected for return to] the 'leedmgend of a mangler for reironing.

This invention relates to an improved type of conveyer mechanism or go back carrier for use in laundrles in combination lVlth a mangler or ironer whereby an attendant at the discharge end of the machine may sort and place pin'tiallyironed pieces in the conveyer for return to the attendant at the feedlng end of the machine for re'iron1ng,w1th

out making it necessary for the attendant at the discharge end of the machine to leave the same.

It is an object of this invention to pro vide an improvedconveyer for use in combination with a mangler or ironer to permit partially dried pieces to be conveniently returned to anattendant at the feeding end ot' the machine for reironing.

It is also an object of this invention to provide an ironer with a conveyer mechanislnto permit an attendant at the discharge end of the ironer to place improperly dried pieces in a conveyer adapted to convey said pieces into a receiving bag positioned adacent the machine at the feeding operators station and having a suitable opening therein, permitting an attendant at the feeding end of the machine to remove the improperly dried pieces from the bag and again feed the same into the ironer :for reironing.

It is an important objectof this invention to provide a laundry mangler or ironer with a conveye'r mechanism atone side of the n'xachine positioned to permit an attendant or folder at the discharge end of the ironer to sort ironed goods and deposit improperly dried pieces into one end of a conveyer which acts to automatically convey such pieces of goods upwardly to be deposited into the upper end of an adjustable bag or container from which the improperly dried pieces may be removed at intervals to permit a feeder attendant at the feeding end of the ironer to again feed said pieces into the ironer for reironing.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the "accom-' panying drawmgs.

The reference numeral 1 indicates as a whole a laundry mangler or ironer of any desired type or 'construction having a laundry receiving counter or table 2 positioned across the discharge end of the ironer in a convenient position to permit an attendant at the discharge end of the machine to receive. sort and fold the ironed pieces of laundry as they come from theironer. To permit the pieces of laundry which are not properly dried to be returned to the attendant at the feeding end of the ironeran improvedconvey'er mechanism is provided positioned at one side of the machine having one end easily accessible by the attendant at the discharge end of the machine while the other end is positioned convenient for access by an attendant at the iteedingend of'the machine. M

The improved mechauismof this invention is adjustably supported by: ropes or cables Figure 2 is an enlarged vertical detail sec- 3 each carrying a bail or yoke 4. The upper bail 4 has the ends thereof securely fastened to the opposite sides of a three sided box or container ointo the open side oi: which the upper end of two parallel chute side boards 6 project. The upper ends of the chute side boards 6 are supported by means of brackets 7 connected to the bearing supports 8 of an upper conveyer roll 9. Mounted on one end of the shaft of the upper conveyor roller 9 is a grooved sheave or pulley 10 around which an endless driving belt 11 is trained. The endless driving belt is also engaged around a sheave or small pulley 12 supported on one end of a transverse auxiliary shaft 13 which projects across the top of the conveyer chute and is journalcd in suitable bearing brackets 14 secured to the chute side boards 6. Engaged on the opposite end of the transverse shaft 13 is a sheave or pulley 15 around which an endless driving belt- 16 is trained. The belt 16 is also trained around a sheave or pulley 17 mounted on one end oi the shaft of a driving motor 18. The motor 1? is secured upon a supporting bracket 19 secured to the upper ends of the chute side boards 6.

Securely mounted on the outer side of each of the chute side boards 6 are a plurality of brackets 20 the lower ends of which have integrally formed thereon an inwardly directed arm 21 provided with a notch at 252 (Figure 7). The two opposite arms 21 are connected by a transverse bar 23 which connects the two brackets and affords a support for a chute floor or bottom board 24. The arms 21 and the cross bar 23 hold the bottom board 524: in position spaced from the lower edges of the two side boards 6. It will thus be seen that the chute comprises the two side boards 6 and the bottom board 2-1 which is spaced from the lower edges of said side boards to atiord longitudinal slots or-openings 25 which extend substantially the entire length of the chute.

These slots or openings are provided to prevent articles carried by the conveyer from becoming caught or pinched beneath the side boards and said convever.

Positioned adjacent the outer side of; the lower end of each of the side boards 6 is a bearing bracket 26 which projects downwardly below the bottom board 24. Journaled in the two bearing brackets 26 is a lower conveyor roller 27. Integrally formed or rigidly secured to each of the bearing brackets 26 is a shield or guard 28 having a curved inner edge 29. The two guards 28 are positioned with the curved edges 29 op. posite one another to afi ord a guide space permitting articles to be conveniently directed within the lower end of the chute upon an endless conveyor belt 30. The endless conveyor belt may be made of canvass or any other suitable material, and passes over the upper feed roller 9 into the chute above the bottom board 24 with the lower hight of said conveyor 30 passing around the lower roller 27 behind the shields or guards 28 and then passing upwardly beneath the chute bottom board 24 over an idler roller 3] journaled transversely beneath the chute in suitable brackets fastened to the outer sides of the chute side boards (3.

For the purpose of adiusting the tension of the endless conveyor 30 each of the brackets 26 is provided with a pair of parallel slots 33 through which set screws or locking bolts 34 engage to hold the brackets 26 rigidly secured in a set position adjacent a U- shaped supporting bracket 35 one of which is secured on the outer side of the lower portion of each of the chute side boards 6 (Figure 5). Also secured on each of the brackets 26 is an internally threaded nut or block 36 through which an adjusting screw 37 is threaded. \Vhen the set screws 34 are loosened the adjusting screw or bolt 37 is adapted to be rotated to move the respective bracket upwardly or downwardly'eithcr to loosen or tighten the belt 30. as desired. The adjusting screw 37 is supported in the. outwardly directed flanges 38 of the bracket 35.

Pieces of laundry or other articles deposited in the lower end oi the chute upon the endless conveyor 30 are adapted to be conducted upwardly and discharged over the upper end of the coveycr into the box or hopper 5. The bottom of the hopper 5 is open to permit the articles to drop thcrethrough into a spout, bag, or receptacle 39 constructed of canvas or any other suitable material. The bag 39 is substantially rectangular in shape hav mg four sides, the upper edges of which are provided with eyelets or any other suitable means whereby the bag may be rcmovably secured to the lower edge of the hopper or box 5. The. lower end of the bag 39 is closed by means of a. wooden bottom or floor 40. One side 41 of the bag is provided with an opening 42 at its lower end to permit articles to be readily taken from the bag (Figure 3). Connected to two opposite side walls of the bag are a plurality of shirr strings 4-3 which project through eyelets or sultable openings in the bag wall 41 to permit two opposite sides of the wall to be shirrcd or plaitcd, as at 41:, to cause the upper portion of the bag wall 41 to assume an inclined position to alford a guide wall or battle 1-5 in the upper portion of the bag adapted to direct the articles being deposited in said bag downwardly toward the lower rear corner of the bag in a convenlent position for removal through the opening 4-2. The shirring of the bag by the strings 43 serves to position the bottom 40 of the bag in an inclined position, as clearly illustrated in Figure 2, thereby tending to retain the articles in the lower rear portion of themangler or ironer 1 and has attached to one edge thereof one end of a cord46, the other end of which is adapted to be engaged across the outer face of the bag wall 4:1 to permit the lower end of the cord 46to be engaged in an eyelet or ring 47 attached to an opposite edge of said bag. The cord 46 may be tied to cause the bag to assume a slightly inclined position with respect to the side of the mangler or ironer I, as shown in' dotted lines in Figure 4:. This turning of the bag positions the opening 42 near the lower end thereof in a more convenient'place'topermit an attendant at the feeding end of the glangler to withdraw articles a from the ag. a The operation is as follows:

The piecesof laundry or articles to be ironed are'delivered to the feeding end of the mangler or ironer 1 where an attendant is adapted to feed the articles into the main glen The articles as they are conducted through .themangler are ironed by the rolls and are finally delivered through the discharge end of the machine ontothe receiving table 2. A second attendant or folder is positioned at the table 2 and as the ironed articles are delivered on said table inspects said articles to see that they are properly dried. than a piece. of laundryor'an article is discovered whichis not properly dried the attendant separates said articles from those that are thoroughly dried and deposits the samein the openlower end of the chute upon the endless conveyer 30. The guards 28 which cover the ends of the lower conveyer feed roller 27 prevent the article from coming in contact with the roller so that any trailing ends of the article will not l)- come tangled or caught between the roller and the brackets 26-. a The inclined edges 29 of the guards 28 form the upper ends of the guards 28 into fingers 28*wh1'ch Pro oct upwardly into the-chutea short distance to close a portion of the slots 25 and serve to with the lower roller. i

The articles which are deposited upon'the belt into the hopper or box 5, permitting the articles to dropinto the bag 39 against the inclined haflle wall or apron (Figure 2) which tends to direct the articles downwardly toward the rear wall of the bag and into the lower rear portion, thereby 0hviating any tendency for the articles to find their Way out of theopening 42. The inclined bafilc Wall 45 is formed by shirring two opposite sides of the bag by means of the four shirr strings 43, as clearly illustrated in Figures 2 and 3. The shirring of two of the side walls also acts to incline the bottom 40 of the bag to form a pocket in the lower rear end of the bag for the articles deposited therein. To conveniently. tilt or turnthe bagii?) the cord lti may be tightened.

sothat the opening 42 is slightly turned at an angle with respect to the side of the man gler 1 so that the attendant at the feeding end of the inangler maymore conveniently reach into the opening42 to remove the articles or pieces of laundry from the bag so that they may again be fedwthrough the mangler to be reironed. 1

By providinga mangleror ironer with an improved conveyer mechanism of the type described a convenient arrangement is afforded for rapidly delivering improperly dried pieces of laundry from the discharge end of the mangler back to the feeding end without requiring the attendant at the dis charge end to leaveher position. This arrangement, furthern'iore, provides a considerable saving of time due to the fact that the attendant need not collect the improperly case the conveyer mechanis'm is not needed.

the samemay be pulled upwardly toward the ceiling by means of the supporting cables 3 justing the position of the chute with respect to the box or hopper'f) so that the chute may assume any desired inclination. If desired the conveyor mechanism when raised may be pivoted or swung about its upper sup port into an out of the way position to permit convenient access to the ironer when necessary. a
