CHICAGO, ILLINOIS, AY CORPORATION OF ILLINOIS DISPATCH CONVEYER FOR NEWSPAPERS 0R THE LIKE Application filed September 19, 1929. Serial No; 393,632'.

This invention relates to dispatch conveyers for use in newspaper printing plants or like establishments, and has for its primary object the provision of improvements adapted to prevent choke-ups at points where the papers pass around curves in the conveyer system.

Other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to theV drawings;

Figure 1 Vis a side elevation of a device in which my invention is embodied;

Fig. 2 is a top plan view thereof;

Fig. 3 is a front elevation; and i Fig. 4 is a vertical, sectional and'elevational view taken centrally and longitudinallyof Fig. 1, this ligure showing also in dotted lines the position-to which certain of the parts may be moved in case of a choke-up at a curve in the conveyer system. 1

The part of the conveyor shown in 1the drawings is that at which the papersy are transferred' from a vertical to a horizontal section of the conveyer, although it will be understood that the situation is substantially the same and substantially the same mechanism may be used at a'point where the transfer is from a horizontal to a vertical section, and it is desired that the claims hereinafter made shall be considered as applicable to any part of the conveyer system whereA a change in the direction of travel ofzthep'apers occurs.

As is best shown in Figure i4, the vertical part of the conveyer consists of

adjacent wires

21 and 22, between which the papers 23 are clamped and lifted upwardly as the wires pass around oppositely turning pulleys 24v and 25 at the top of theirv course of travel. Said' wires are ordinarily providedin series across the width ofthe conveyer, the

wires

21 and 22 being matched as shown in Figure 4, and the pairs of matched wires being spaced apart as shown in Figures 2 and 3, which figures, however, are broken away and show only two I sets of wiresalthough the number is usually greater in ordinary practice. l

The speclic form of material yusedl inthe yly described.

.38 carries a pulley 41, which, together with a conveyer construction is not of particular importance to the invention .so long as itis understood that in the verticaliiight the papers are carried between two vco-acting conveyer members such as the

wires

21 and 22,

a horizontal conveyer which' will'be present- The `pulley 25 is carried uponV a shaft 26 which also carries agear 27 meshingjwith a gear 28 carried by ashaft 29 which carries a sprocket 31 adapted to be driven from a suitable source of power by means of, a chain 32 (see Fig. 1). The gear 28 meshes witha gear 33 mounted on a stud '34 which is jour- Y naled in a fixed bearing 35 in a framel 36,

said gear 33 meshing witha gear 37 upon a stud 38 carried by an arm 39 which is pivotally mounted upon the stud 34. Said stud Y shown) for the purpose of driving another part of the conveyer.

The horizontal portion of the conveyer above mentioned consists of wires 49 running over the pulley 25 which, as shown in Figure 2, is double and over a pulley (not shown) at the opposite end of the course of travel of said conveyer wires. The horizontal wires are also arranged in series as shownin Figfure 2 and may be provided in anydesired number, it being understood thatjthey will VVbeV driven in Synchronism from the same source of power. A guide roller 51 is pro-.

vided for maintaining the wires 49 at` a.A

proper level, said roller being carried upon an arm 52 pivoted at 53 to the frame, the pivot 53 also carrying an arm 54 equipped with a chain tightener 55 engaging the upper and are delivered onto or are received from y course of the chain 48 to hold the same at proper distance beneath the wire 49.

A guide roller 56 carried by an arm 57 pivoted at 58 to the frame serves to liold the wires 22 of the vertical conveyer section in close proximity to the wires 2l, so that the papers will be gripped between the said wires 2l and 22 and carried upwardly to a point of transfer from the vertical to the horizontal sections of the conveyer. Tie rods 59 and 6l are provided between the arms 39 at the opposite sides of the conveyer (see Fig. 2) to hold the structure together. The weights 46 are secured to the arms 45 by meansof set-screws 62 and are-adapted to rest upon adjusting screws 63 provided in brackets 64 secured by means of screws 65 to the frame 36. By adjusting the screws 63 the position of the arms, 39, 45 may be varied to vary the tension of the wires 44 on the papers.

It will be noted that the upper pulleys 24 and the wires 2l are also carried upon the arm 39 so that adjustment of the latter serves to move said pulleys 24 toward or away from the pulleys 25, thus varying the tension on the wires 2l and 22, between which the papers are carried upwardly.

In the event that there is an accumulation of the papers at the turn in the conveyer, resulting in a choke-up, which, in the past has necessitated stopping the press until such condition could be remedied, the

arms

39, 45 will be moved away, carrying the

wires

44 and 21 therewith so as to relieve the pressure upon the papers and allow them to be carried on by the conveyer without the necessityof stopping the press and without requiring any action on the part of the attendant. The weights 46 are calculated to provide the desired degree of tension and to permit the wires 44 and 2l to be automatically thrown out of normal position under the circumstances just mentioned. rlfhe extent of movement of the

arms

39, 45 and associated parts varies, of course, according to the degree of congestion. It will be observed from Figure 4, however, that the wires 2l and 44 may be moved a considerable distance away from the wires 22 and from the inner end of the horizontal conveyer section 49, the parts being adapted to be automaticaly returned to normal position by means of the weights 46 when the congestion is relieved.

f By avoiding the delays incident to chokeups and by providing just the right tension uponthe papers in the vertical portions of the conveyer system and at the turn, the device herein described materially increases the efficiency of a newspaper plant and effects considerable savings in time and in labor costs.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may pers around the curve from one of said secbe made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the construction hereinbefore described being merely a preferred embodiment thereof.
