To all whom it may con/berm:

Be it known that I, CHARLES P. Co'rTRELii, a citizen of the United States, and a resident of Westerly, in the county "of Washington and State of Rhode Island, have invented anew and useful Improvement in -M-achinery' .for Cutting and Delivering-Sheets ofPaper and other Material, of which-the following is a s ecifioation.

for cutting sheets from a running web and delivering themflat upon a receiving boardor table; and it consists in the combinations 3 hereinafter described and claimed comprising cutters and such aboard or table. I

- In the accompanying d12LW1I1gS,Wl11Cl1 illustrate my invention, Figure 1 is a side e1e'- vation of machinery embodying my invention; Fig. 2, a vertical section parallel with Fig. 1. Figs. 3 and 4 are detail viewswhich will behereinafter ex lained. 1

- Y is framing whic may be part of or an adjunct to theframing of a web-printing machine in connection with which this cutting anddelivery machinery is used. 7 In the upper part of thisframing are the bearings for the shafts 11 11* of thetwo rotary'cuttingreels 12 12*, and at a suitable distance above the'base of said framing and below and for- Ward of the cutting-reels is the horizontal receiving-table 1 3, carried by upright screws 2 1 There are two of these screws, one on each side of'the table. The lower ends of these screws are fitted to turn in bearings' 21* in the bed-plate and their upper ends in bearings in brackets-.22 on the framing, the said -screws be'ing so fitted to said bearings as to be confined vertically. The said screws are threaded into the table-supports 22*, so that by (iurning themthe table is raised and lowere 1 I Directly under distance therefrom equal to about half the length of the sheets to be out there is an intermittently-operating feeding device con sisting of a pair of feeding-reels composed of shafts 14 14* and disks 1515*. shaft 14 is supported in fixed bearings in the framing- 10', and the-reel shaft 14* is sup ported in bearings in the, downwardly-prohis inventlon relates to machinery The reel-' which is supported in bearingsin the framing 10. Between oneof said arms 16 and an' iabutment 18 on the framing there is applied.

a pushing-spring.'16*, which exerts a constant tendency to that 14 15. .The said rock-shaft 17 has an upwardly-proj ecting' arm 19 arranged oppo-.

site to a cam23 which is provided on the shaft 11* of the cutting-reel 12* and which serves,

by its action on said arm 19 to separate the ifeeding-reel 14* 15* from its 'fel ow. The lsaid rock-shaft and cam and the arm 19 are shown separately in Fig. 3. I

reels thereis a stationary guide 24 for the end I ofthe web and for the sheets cut therefrom,

. and between the feeding-reels and the table there is a stationary guide 25, which is so curved under the reel 14* 15* as to direct the out sheets, from the reels toward a position over the table and under stationary sheetguides 26, which are arranged at a short distance above the table.

rangeda set of sheet-knockers 27, carried by a horizontal rock-shaft 28, which is support ed in bearings in theiframing. The ends ofthese knockers are turned downward to enter between the guides 25 and 26. For the Between the feedingreel 14* and thesaid guide 26 there is ar-l 7 5 purposeof producing the downw'ard'and upward movement of these knockers thejroc shaft is furnished-with two arms 29.30, the

arm 29 being connected, with a yoke-rodwhichis depressed by a cam 32 on the 31,- v cutter-reel shaft 11*, and the arm 'having a pushing-spring 33 appliedbetween it and an abutment 33* on the framing. Fig. 4 is a side view of said cam and yoke-rod.

'- Atthe front edge of the table a stationary p sheet-stop 34 is carried by brackets 35 -'on the cutting-reels and at. a.

the framing. At the rearedge of'the table is a sheet-jogger '36, carried by a rock-shaft 37, in fixed bearings in the framing.

so that all three rock-shaftsmay be actuated '95 I carried by rock-shafts 38, having 39, carried by the,

driven through an less screw 55 on its lower end which meshes.

by one cam 40 on a rotary shaft 41, the said cam being engaged by a yoke-rod 42 with an arm 43 on the rock-shaft 37 and the said arm having applied to it a pushing-sprin 44, which abuts against a stud 44* on the aming.

The shaft 41 before mentioned is represented as the driving-shaft, and it carries a gear 45, which is geared, as shown in Fig. 1, through an intermediate loose gear 46 with a gear 47 on the shaft 1 1 of the cutter-reel 12.

he gears are so proportioned that the cuttingreels having single cutters make two revolutions for every revolution of the drivingshaft. The cam 40 being a double one produces the action of the several j oggers 36 and 38* every time a sheet is deposited upon the table. The knockers 27 being operated by the cam 23 on the cutting-reel shaft 11* also operate on every sheet as its tail end passes by the feeding-reels. The feeding-reel shaft 14 is intermediate loose gear 48 from a gear like 47 on the cutter-reel shaft 1 1, the said intermediate gear meshing with a gear 49 on said reel-shaft. These gears on the cutting-reel shaft and feeding-reel shaft are so proportioned that the peripherical speed of the feeding-reel is slightly in excess of that of the cutters. The feeding-reel 15* is driven by contact with the positively-driven one 15. The screws 21,which serve to slowly depress the table as the pile of the sheets deposited upon it increases, derive their motion from the feeding-reel shaft 14 through a vertical shaft 50 and a horizontal shaft 51 and two horizontal shafts 52 52*, said shaft 50 having its bearing in brackets 53 on the framing and said shafts 51 52 52* having their bearings stands 58 on the bed-plate 20. The shaft 51 is geared with the feeding-reel shaft 14 by bevel-gears 54, and it has an endwith a worm-gear 55 on the shaft 51. The said shaft 51 has on it two bevel-gears 56, which mesh, respectively, with bevel-gears 57 on the two shafts 5.2 52*, and theselatt'er shafts are geared, respectively, with the two screws 21 by bevel-gears 59 60.

The web from which the sheets are to be out is fed down between the cutting-reels by any suitable means-for example, by feeding-in rollers 61,such as are commonly used in such machinery-and its end passes down freely through the guide 24 and between the feedingreels 15 15*, which are then separated by the cam 23-, so that their operation is in termitted. When a proper portion of the websay about half the length of the sheet to be cuthas passed between the feedingreels, the said cam passes by the roller at the end of the arm 19 of the rock-shaft 17 and allows the spring 16* to so push the reel 15* toward that 15 that the web is. seized between said reels at about the same time the blades of the cutters come together and sever the web, leaving the severed sheet under the control of the feeding-reels, which, running at a greater speed than the cutters and feeding-in rollers 61, so carry it forward over the curved guide 25 that a space is left between it and the following end of the sheet. While the sheet thus passes forward, the knockers 27 are raised out of its way, and it continues onward under the guide 26 and over the table until its front end strikes the stop 34, when the knockers 27, being depressed by the cam '32, knock down its rear end upon the table,

where it is brought to its proper position by the several j oggers 36 and 38*. The knockers 27 having thus knocked down the sheet are quickly raised above the guides 25 26 by the action of the spring 33 in time to afford free passage for the front end of the succeeding sheet and remain so raised until the whole length of the latter sheet has arrived over the table, when they are again depressed.

at I claim as my invention is 1. The combination with cutters for cutting sheets from a running web and a table for receiving the so-cut sheets, of an intermittently-operated sheet-feeding device located between the said cutters and table having a speed reater than that of the continu ous run of t e web and of the movement of the cutters and arranged and operated to permit the uncut web to pass through it and to engage the same as and after the sheets have been severed from the web, for carrying the severed sheets to the table.

2. The combination with cutters for cutting sheets from a running web and a table for receiving the so-cut sheets, of sheet-feeding reels between said cutters and table having a speed reater than that of the continuous run of t e web and of the movement of the cutters, means for separating said reels while the uncut web is passing between them and means for pressing them together during and after the severing of the sheets from the web for carr g the severed sheets to the table.

3. The combination with cutters for cutting sheets from a running web and a table for receiving the so-cut sheets, of a sheet-feeding device between said cutters and table, a guide between said sheet-feeding device and table for directing the sheets from said sheetfeeding device over the table, a second guide arranged over the table, and knockers arranged to operate between said guides for knocking down the tail ends of the sheets as" they arrive over the table.
