7 1o all whom t may concern:

Be it known that we, WILLIAM SLAU- have invented certain new and useful lmprovements in Rotary Assembling-Machines, of which the following is a specification.

Our invention relates to gathering or stuing machines for use in making books, pamphlets, etc., or in assembling the several sections of a Sunday newspaper.

Broadly speaking, our invention consists of a series of holders each containing one of the sections to be assembled, a. means for dis* charging one of the sections from each holder in timed relation to the other, means for delivering said section to a conveyer operating in timed relation to the aforesaid means, and in means for opening one or more folded sections and placingy them around the other sections to form a cover.

A prime object of our invention especially for newspaper work is to provide mechanism which will accomplish the above results at high speed, as with modern printing presses the various'sections are delivered at the rate of many thousand per hour. Our improved machine will therefore assemble and deliver several hundred complete bundles per .minute.

To these ends our invention comprises the various devices hereinafter described and illustrated in the accompanyingdrawings in wliich Figure 1 is a diagrammatic plan view of the complete machine; Fig. 2 is a diagrammatic elevation of the conveyer and delivery rollers. Fig. 3 is a plan view of a part of a portion of the receiving saddle. Fig.` 4 is an enlarged cross section through the machine. Fig. 5 is a diagrammatic view 4similai' to Fig. 4 of a modification thereof.' Fig. 6 isa longitudinal section through one of the rotary suckers. Fig. 7 is a diagram showing a bundle of gathered sheets on the conveyer. Fig. 8 is a similar diagram show- 1 the endless belt 3 mounted on the the preferred construction is shown in Fig. 4 in which the bottom of the chute comprises pulleys 4 land having the intermediate supporting roller 6. rllhe pulley 4 is mounted on a burgh, Allegheny county, Pennsylvania,

ing a cover dropping over the gatheredI sheets.

rlhe machine consists of a series of chutes 1 containing the sheets 2 standing on a folded edge therein. rfhe chutes l may be provided with a plain bottom of anydesired material, the smoother' the better, but

shaft 7 which also carries a small brake drum 8. A brake shoe 9 is fastened to a lever 10 which'is pivoted on the pin 11. A weight 12 adjustably mounted on the lever 10 Serves to vary the braking effect. At the lower end of the pile of sheets 2 there is mounted a rotary sucker 13, a rotary sucker 14 and a gripping roller 15. Between the suckers 13 and 14 there is placed a shaft 1G carrying several pulleys 17 and a gear 18. The gear 18 drives teeth 19 upon the suckers 18 and 14. The gripping roller 15 is driven by the gear teeth 20 upon the sucker 14. A third sucker 21 is placed adjacent to the sucker 14 and driven thereby. The shafts 22 and 23 are provided with several pulleys 24 and 25 respectively; these pulleys being in the same vertical planes as the pulleys 17, and the grooves 26 in the suckers 14 and 21. Small belts or tapes 27 run over the pulleys 17 and 24 and the sucker 14 and similar tapes 28 run over the pulleys 25 and the sucker 21. A stationary guide or saddlep 29 made preferably of thin sheet metal is supported by the standards 3() secured to the frame 31 of the machine. The upper edge of the saddle 29 is serrated as shown in Fig.

2; one of these sei-rations is opposite each pulley to which power may be applied to drive the whole machine. The sucker 13 operates merely to strip the sheets 2 off the pile, while the sucker 14 assists in this operation and also carries the paper around approximately a half circumference and delivers it between itself and sucker 21.

All the suckers are of similar construction, the difference being in the amount of angular travel during which the suction effect .is operated. All the suckers consist of a shell 40'mounted on annular bearings 41 mounted on a tube 44; the tube 44 is 'mounted lon sliding guides 45 controlled by the springs 46, which act to keep the valve 43 in close contact with the bore of the shell 40. The valve 43 is provided with a port 47 communicating with the interior of the tube 44 through which a partial vacuum may be created by any desired means.

Small ports 48 are out in the shell 40. The

poits 48 may be lcalled sucker ports and the port 47 the suction-port, and there being a partial vacuum maintained constantly in port 47, there will be a partial vacuum created in each of the ports 48 as they come into communication with the port 47 which will be broken when the port 48 reaches the relief port 49. In sucker 13 the port 47 is merely wide enough to cover two of the sucker ports 48: in this way the moving force of the sucker 13 is confinedto a direction tangent to its circumference. The Y sucker ports 48 cover about one fourth of the shell 40, this being sufficient tofmove the paper until it is engaged by other means. In sucker 14 however the sucker ports 48 extend about half way aroundthe circumference and the port 50 in the valve 51 is correspondingly wider the suction effect being maintained for about a half revolution. In sucker 21 the valve 52 may be a duplicate of the valve43. The suckers 13 and 14 together strip the sheet off the end of the pile; after it moves a slight amount it is gripped between the sucker 14 and the gripping roller 15 and carried around between the suckers 14 and 21. If it is merely desired .to gather the papersas shown in Fig. 7 the sucker 21 may be made inoperative by cutting oil' the suction thereto in which case the papers would be delivered between the tape 27 and the saddle 29, and would fall von the flights In case however, it is desired to put a cover over the pile of sections as shown at 54, in Fig. 8 the sucker 211s made operative and it draws one edge of the folded sheettoward itself, the other edge being drawn toward the sucker 14 which results in the cover being delivered astraddle of the saddle 29 and any gathered sections thereon, the downconiing edges being guided b v the

tapes

27 and 28. In case it is desired to have each section except the irst inclose all the previous sections, so that all the sections except the first are in efl'eet covers, all the suckers may be operated to produce. this result and each delivered bundle would be a con'ibination ofy inserts. The dotted rectangle 54 represents a completed bundle pist about to be discharged froln the machine.

'ing the loose edges may not do so.

.the case with the cover section for a news:

paper, it will be seen that the suckers 14 and 21 can act directly only on the outside thickness of paper at the end of the cover containing the loose edges; the end of the cover containing the folded edge Will open with certainty but the end of the cover hav- F or this reason the saddle 29 has been serrated as shown in Fig. 2, the high points 55' of the saddle corresponding to the folded edge of the cover and the low portions 56 to the loose edge of the cover this giving the loose edges of the covei` more time to open.

In addition to the aliove, we provide nozzles 57 supplied by an air pipe 58 for blowing a jet of air between the folded edges of the cover as they are delivered from between the suckers 14 and 21, to insure the complete separation of the inner sheets of the cover.

The assembled papers are delivered olf the left end of the saddle 29 as shown in Fig. 1 and passed betwe n a pair of guides 59 which lead into the elivery rollers 60,

4which 'deliver them .into any suitable rethe shaft 33 is such that the conveyer chains 52 move an amount equal to the distance from center to center of chutes 1 for each revolution of the suckers so that in passing aseries of chutes one paper'from each chute will be deliyered at the same point on the conveyer chains 52 to form an assembled pile.

In Fig. 5 we have shown a modification of the arrangement shown in Fig. 4 in which separate stripping suckers 61 are provided to strip the sheet off' the pile; these suckers would 'be duplicates of sucker 13. A pair of gripping-rollers 62 engages the sheet after it is moved a couple of inches and pushes the saine through the curved guide G3 which delivers the edge of the sheet between a pair of opening suckers (i4- whieh may be duplicates of sucker 21. The lsaddle 29 and the

tapes

27 and 28 may be the salue as previously shown. In the arrangement shown in Fig. 5 four suckers are required to do the work of the three shown in Fig. 4 but in many cases this arrange- `nient might have practical advantages as the relation between the lower end of the pile of papers and the saddle 29 can be varied greatly to suit the conditions of service.

Froin the. above it will be seen that we have provided simple and elicicnt mechanisln for the purpose described, the details of which may be widely varied from those iaoaeoe lshown `without departing from the spirit of our invention as covered by the following claims.
