FEEDING DEVICE FOR MANGLES.

Application filed September 17, 1921.

This invention relates to feeding devices for niangles and similar machines, and has for its principal object to provide a device which will feed a row of napkins, towels and the like to a mangle in such a manner that the forward edges thereof will be in ali nment.

/lnother object of the invention is to provide a device of said character which is operated in time from a folding machine so that the aligning forward edges of the napkins, towels and the like will reach a certain position for action there-on by said folding machine.

Another obj ect ofthe invention is to provide a device of said character which is intermittent inoperation to enable the loading thereon Iof the napkins, towels and the like. A. further object of the invention is to provide a device of said character which is of simple construction and positive in action.

With the above and other objects in view as will be readily understood, the invention will be hereinafter fully described as illustated in the accompanying drawings and the novel features thereof will be distinctly pointed out in the appended claims.

In the drawings similar characters of reference are used to designate corresponding parts.

Figure 1 is a rear elevation of a feeding device for mangles constructed in accordance with my invention,

F ig. 2 is a side `elevati-on of the same connected in operative relation with a folding machine,

Fig. 3 illustrates a holder of the feeding device in normal position loaded with a napkin,

Fig. 4 is a similar view illustrating the holder in its up position and the napkin after falling therefrom, Y

Fig. 5 is a plan view to illustrate the forward aligning edges of the napkins after falling from the holders, and

Fig. 6 is a fragmental view of a shelf of a holder with cloth covering the flange thereof.

vWhen napkins, towels and the like .are fed into mangles and similar machines by several operators, theforward edges of the same are out of alignment due to the operators being unable to work in unison. The forward ec ges of the napkins being out of alignment at the. beginning, continue thru serial No. 501,405.

the mangle as started, and when thru the n'iangle, said forward edges of the napkins are still out of alignment. in using a folding machine of the character disclosed in my application No. 346,742, fil-ed December 22, 1919, it is essential that the forward edges of the napkins be in alignment in order that the napkins may be folded evenly. This is the purpose of designing the feeding device of the present invention. v

Referring to the drawings, l represents the frame of a mangle which supports the usual rollers as 2 over the steam sections 3, and a roller 4 carrying endless belts 5 Y around a rod or bar 6 serving as a conveyor for feeding napkins, towels and the like to the rollers 2. l/Vhen napkins are laid upon the belts 5 by several operators standing in front of the roller 4 asis the usual practice, the forward edges of the napkins are not in transverse alignment due to each operator not being able to apply the napkins upon the belts at the .same instant and at a uniform distance from the roller 4. As a result of the forward edges of the napkins not being in transverse alignment when entering the mangi-e, they continue thru and leave the mangle with their forward edges out of transverse alignment. In using a folding` machine in connection with the mangle, it is important that the forward edges of the napkins when they leave the mangle should be in transverse alignment, and the present invention was designed to feed the napkins into the mangle with their forward edges in transverse alignment, so that upon leaving the mangle, their forward edges would be in transverse alignment.

Extending from the` sides of the frame l are tip-

rights

7 and 8, in which is rotatably mounted a rocking shaft 9 supporting a plurality of dependent holders as 10 having shelves 1l with upturned edges 12 for receiving napkins 13. The upturned edges l2 are preferably covered with cloth 14 orfother suitable material for preventing slipping of the napkins. The shaft 9 extends trans versely in the same direction as the roller 4, and the shelves 1l of the holders 10 extend rearwardly beyond said roller and at right angles thereto, and are formed on the arc of a circle. The holders l() are rotatably and slidably adiustable on the shaft i?, to which screws at in any suitable position. For,

rocking the shaft 9 intermittently crank arms 1G and 17 are fixed to the ends thereof, and to these and to the upper free ends of

lever arms

18 and 19, which are fixed to the ends of a shaft 20 rotatably mounted in the frame 1 as at 21, are pivoted links 22 and 2?) respectively. An arm 211 is fixed to the shaft 20, and to this is 'pivoted a rod 25, which is pivotally connected to the upper' end of a lever bar 26 pivotally supported by a short shaft 2?' carried by brackets 2S and 29. To the lower end of the lever bar 26 is pivoted a rod 30, the other end of which is fixed to a bifurcated head 31 for straddling a shaft 32 of a folding` machine indicated by 33. Fixed to the `shaft 32 is a suitable cam 311 in the form of a disc for engaging a lug 35 extending from the side of the head 3l, and having a recess 36 for receiving said lug. llleighted arms as 37 formed integrally with and extending forwardly from the

lever arms

18 and 19 tend to cause the lug 35 of the head 31 to engage the cam 34 and retain the holders 10 in their normal positions for being loaded with napkins. The

weights

38 and 39 may be adjusted to any suitable position upon their arms by means of set screws or any other suitable means. Each time the cam 34 advances to the proper position for allowing the lug 35 of the head 31 to enter ,the recess ltl'thereof, the

weights

38 and 39 cause the holders 10 to move forwardly, and then'they are moved rearwardly to normal position by the action of said cam. This produces a quick forward swing of the holders 10, a slow return, and a rest at their normal positions to give time for he loading thereof with napkins.

In practice, and when the holders 10 and all parts of the machine are in their normal positions as best shown in Fig. 2; the operators. standing before the roller l, hang damp napkins 13 over the edges 12 and upon the sielves 11 of the holders 10 with their for- 7ard edges 4:0 against the backs of the holders as shown in Fig. S. As the shaft 32 of the folder 33 revolves, it rotates the cam 34e, and the instant the recess 3f thereof is opposite the lug 35 of the head 3l, said lug moves therein due to the weight-s 3S and 39,' which action causes the holders l10 to swing forwardly to the position shown in Fig. 2l, and the napkins 1 3 fall therefrom upon the belts 5 with their forward edges i0 in alignment as shown in Fig. As the cam 3st continues to rotate, it forces the lug 35 out of the reess thereof, and thereby returns the holders l() to their original or normal positions, and retains them at rest to be loaded by the operators. Each set of loaded napkins fall upon the belts 5 at regular intervals with their lforward edges in alignment, and as they enter the mangle with their forward edges in alignment, they leave in the same relative positions, and as the movement of the holders is timed with the action of the folding machine, each set of napkins reach the folding machine at the proper time with their forward edges in alignment.

lt is to be understood that slight changes in the details of construction may be made for carrying out the purpose of this invention within the scope of the claims.
