Specification of Letters Patent.

T0 all whom it may concern.'

Be it known that I, FREDERICK W. Frml LERToN, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Newspaper-Conveyers, of which the following is'a specification; My invention relates to improvements in newspaper conveyers and 'more particularly to a conveyer, which is adapted for use in connection with the modern printing press.

An object of my invention is to provide a conveyer for newspapers and other printed papers, which will receive the papers from the press and transmit them by any convenient route to a delivery table where the papers are usually stacked and counted.

My conveyer isiparticularly adapted to the transmission of folded papers without smearing the fresh printers ink through contact with the belts and without creasing or breaking the folded papers where the conveyer changes direction. It also reduces wear between the papers and belts and is practically noiseless My improvement also vcauses a pair of said belts to tightly and evenly grip and accommodate printed papers of different sizes and weights with substantially uniform pressure whereby the papers are prevented yfrom creeping and becoming disarranged or damaged. The Vconstruction also admits of quickly repairing broken or damaged parts with ease in case of accident.

The mechanism with which the conveyer is operated is also simple in construction and 'l light in operation being applied in use around sha'rp corners and through ceilings and walls with little difficulty.

In the accompanying drawing forming part of this specification, Figure 1 is a diagrammatic view, showing the application of my invention to several of the dierent conditions of a newspaper-'conveying system; Fig. 2 is an end view of a detail Yof the. conveyer system; Fig. 3 is a plan of adetail of the conveyer system; Fig. 4 is a plan of a portion of one ofrthe belts, and Fig. 5'

is a side view of one of the sets'of pulleys orsheaves.4

In Fig.V 1 of the above drawing is illustrated my improved conveyer having a newsv paper receiver A', a downward to horizontal change in direction B, a horizontal to a The conveyer is adapted to be connectedto a printing press not illustrated to operate by any convenient source of powerin synchronism with the delivery mechanism of the press. As the papers E pass through the conveyer, which may be' of any length desired and fitted with any of the changes of direction shown, to bring the papers to the required delivery point, they are passed on to the table D and stacked and can be removed from the table as desired.

A vprimary feature of my invention consists iniarranging carrier belts composed of substantially endless helical spring wire strands 44, (see Fig. 4), held under tension so that the adjacent sides or'surfaces of cooperating belts are adapted to grip papers between said sides and convey them evenly from one point to another without the papers becoming disarranged or slipping and the freshly printed surfaces smudgedf An embodiment of this idea and other features of novel construction are incorporated inthe apparatus set forth in the following description.

The receiver `A consists of a plurality of sheaves 3 being mounted at substantiallyl equal distances apart upon a shaft 5 and the rammed May a, i915.

belts 2 running over sheaves 3 and 4, the

sheaves 4 mounted in the same manner en the shaft 6, all of said sheaves being of equal diameter, whereby all of the belts 2 are adapted to lie with their upper and. lower sides respectively in approxim atelyl adjacent horizontal planes. The shafts 5 and 6 are journaled 'upon suitable supports such as 7, which are mounted upon the floor or ceiling 8 of the building of a structure containing the conveyer system, the shaft being arranged above an opening 9 in said -loor or ceiling, so that the downward eXtension of vthe conveyer may. pass freely `through vsaid opening. The downward eX- j 100 tension F of the conveyer is composed of a group of belts similar to belts 2 'passing over sheaves 10, (see Fig. 5), on the sha-'ft 6 lying vadjacent to the sheaves 4, and over sheaves 11.011' a shaft 12, which is supported below the ceiling 8. The sheaves 4 andlO are of the/same diameter and the beltsl travel 'at the same surface speed as the belts 2 serving to assist in conveying the papers from a horizontal-direction downwardly on to another group of horizontal belts 14. 'The shaft 12 is of similarV construction to the shaft 6, being providedvith sheaves similar to 4 and lQffgr'the downwardly extending belts 13' latter alsop'as'sing around sheaves 15 on a shaft 16 at the'turn C, the belts 14 passing through an opening 17 in the upper portion of a partition such as 18. After passing throught-"said opening and around the sheavesv onf-,the shaft 16, the papers are assisted in being carried downwardly by downwardly extendingbelts 19 passing over one of the sets of sheaves on the shaft 16, which is similar to the construction illus- I trated in Fig. 5, and over another set of sheaves 20, carried by the shaft 21. The papers upon reaching the lower end of the belt 19 are turned by a laterally'extending set of belts 22 passing around sheaves 23 on a shaft 24, and sheaves on the shaft 21 which are similar to those illustrated in Fig. 5, whereupon the papers are deliveredV upon the table D, which is in the form of la frame having transverse shafts 25 journaled in its ends and carrying sets of sheaves 26 and 27 aroundwhich a set of belts 28 are passed. The papers are deposited upon /the belts 28 and stacked in the usual manner by moving the belts with their upper sides away from the delivery end of the conveyer. p

Arranged above the receiving belts 2 is an auxiliary set of belts 30, traveling over sheaves 31 on the shaft 32 and over sheaves 33 on the'shaft 34, the lower sides of said belts being adapted to coperate with the upper sidesoof the belts 2 to assist in conveying the papers in a forward direction. Situated adjacent the sides of the belts 13, which convey the papers is another auxiliary set of belts 35 having sides which also 'coperate with the adjacent sides of the belts 13 to assist in conveying the papers forwardly in a downward direction upon `the upper sides of the belts 14. The belts 35 pass around sheaves 36 `on a shaft 37, and a set of sheaves similar to the sheaves 10, mounted upon the shaft 34, said shaft 34 and the sheaves which it carries being similar in construction to that illustrated in Fig. 5. At the point where the papers turn from the 'receiving belts 2linto a downward direction and from the belts 13 into a horizontal direction, guides 40 are positioned in the form of guide arms, which are mounted` upon shafts such as 41 and urged against thepapers by springs42, thus assisting the papers in turning evenly without becoming disarranged or damaged. Guides 43 are similarly placed at the turn from a 'horizontal direction, in which the belts 14 travel, into adownward Yiirection assumed by the beltslf).

he horizontal belts 14, the

`All ofthe belts lemployed the conveyer 'are made of helical spring wire 44, whereby vthe sidesor surfaces .of the` blts' areheld under tension to prevent'slippingupon'the pulleys and causing thea'djacent' sides of the beltspvhich coperate tohold the papers ,betweenwth'emand carry theA papers for wardly in a positive ma'nner without creasing and becoming disarranged or the fresh printers ink smudged.

All of the sheaves are driven by link belts and sprockets 45 and' 46 connected 'with their shafts so that the helical belts are positively driven wherever-they pass over the sheaves, whereby the belts are relieved from all driving strain and sagging and are caused to more evenly grip the papers without permitting the papers to collect in bunches. rlhe auxiliary belts are driven by trains of gears 47 land 48 con` nected with shafts 6 and 34 and 16 and 49, i

the use of these offsetting sheaves but where the stretches are long and up and down and the helical belts small in diameter and comparatively weak. Said sheaves are desirable.

Ihe auxiliarybelts 30 run from a high point t0 a low point of travel as compared with the horizontal runs for the purposes of gradually guiding the papers into the bite of the belts and coperating with the guides 40 toturn the papers around a corner.

The delivery table D has motion transmitted to its carrier belts 28 by an eccentric 5l on the shaft 21 and a pawl 52 carried by said eccentric and coperating with the teeth of a ratchetvwheel 53 secured uponthe 22. In this manner a step by step motion at a relatively slower advancing speed than that of the main carrier beltsis imparted to the receivingbelt, causingl the papers to be stacked in `convenient, position to bev counted and handled'by the operators. Thelvai'iou's "'r ev oluble elements and guides are suit'- ably journaled or,l supported by brackets such as 7 and '54, or by thev walls, ceilings and floorscof a building, or by any other Suitable'Supports.

The conyeyer admits of application to the various structures and conditions surrounding printing presses and while the appashaft 25 nearest the delivery end of the belt isos ratus shown illustrates one mode of application wherein the papers are carried from a high to a low point, it is obvious that the invention is applicable with equal eiciency where the transmission is from a low to a high point. Y

In accordance with the patent statutes I have described the principles of operation of my invention-together with the apparatus which I now consider to represent the best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the in vention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
