' B. I STORY, a
' citizen of the 'Unite'dStatea-residing in the borough of Brooklyn','county ofKings, city and State of New York,,have'invent ed a certain new and usefuI Register Device for Feeders, of which the followingisa specification. II I I I This invention relates to improvements in registering devices, in connection With ma chines for feeding sheets to printing presses 1 in use is providedwith mechanism which roller "it is'brought against a gage, and its movement absolutely "arrested. When the haveto be provided-in the form offingers apparatus is employed connectionwith a printing press, thegage is usually arm nged above the impresslon ortakin'g cylinder.
In order to keepthesheetawayfrom the surface .of the impression cylinder, guides which extend beyond thefingers which con stitute the gage. The impression cylinder carries a gripper, so arranged that it will be swung up when itpasses a certain point.-
.The gage is arranged to swingup at the same moment. The parts are so proportioned as to-have' the gage rise with an advanced movement equal to the cylinder speed, so that When the gripper engages with the sheet, the sheet will always be engaged I by the gage or by the gripper, and will never be entirely unsupported. at its front" edge. "This isthe ideal condition. In practice, however, owing to a number of variables,it is found that the gage will leave the I sheet before or after the gripper comes in the thicknesses of sheets, vibrations of thesary to run the contact with. it, but not at the precise moment when the gripper comes 1n contact with the sheet. The front edge of thesheet is, therefore, 'notin absolute control. These variables may consist ofdiiferences' between machine, electrical influences,- rebound of the gripper at high speeds, or may be also caused by improper adjustment where it is necesaccoinmodate di erent work." His a matter of the greatest oiiiiigulty to set the g pp r nnGIsTEn-Dnvicn ron rnnnnns. I

The present type of registering device now jto the poin closed at any angle whichmay be chosen.
ress. at different speeds to. 1
so that it will properly act whenthe speed of the press is changed. It is necessary to attain perfect work-that -the gripper must always engage the sheet at the precise'moment that the gage leaves it, so therewill be no period of time when the front'edgeof the sheet is not under control. I According to the vices are utilized whlch' do not require the sheet to be stopped in order to be gageda These devices permit the sheet to be'always lmder control. objections to the prior. apparatus is that the One of the difficulties and sheet being stopped, must be jerked forward by the grippers at cylinder speed, producing somethlng that is incapable of uniform resent invention, de-
Work, owing to. the numerous different va-. I
riables before-referredto. Unless the line. 5 l
of grippers be uniformly set, the resistance ofthe sheet to motion, from absolute rest,
[ will cause it to wrinkle around the cylinder.
The objects of the invention are to' overcome the difficulties before .pointedout. Ac
cording to my invention, I-avoid'the neces-'-' sity of bringing the sheet to rest. I also produce devices which always keep the sheet under control. I I
Accordin I to my invention, the speed of the sheet mgygbe normal, ormay be slightly" reduced or ac= elerated. Itis brought. gently into Contact with the gage, -sothat it is squared up always remains under con trol, and 1t ontinuously under control up I delivery. This produces the easiest possible gripper motion, because the grippers do not have to turn upon their 'axes so rapidly as they must do with prior apparatuses. As the sheet is always travel ing the'grippers, the latter maybe A, further object of the invention is to' produce a device for accelerating the speed der for final register, if desired. "This makes of the sheetat the moment of delivery. This i allows the stops to beplaced upon the cylinit possible to leave of]? the stops from the cyl I inder sothat the leading margin of the sheet may be increased or,'decreased,' as desired.
.- I In feedingcovers'or insert sheets to the fglgier f a web magmas, t s poss l th this device to adjustthe front edge of the sheet relative to the webs while the machine is in operation. 1
These and further objects will more fully appear from the following specification and accompanying drawings, conslderedtogether or separately.

Figsl 8, 9 and 10 are diagrammatic views showing the operation of the device illustrated in Figs. 1 to 6. Figs. 11, 12 and 13 are similar Views of the device illustrated in Fig. 7. Figfll is a diagrammatic view of a modified form of feeding device. Fi s. 15 and 16 are detail views of an impression cylinder, showing the registering stop. Fig. 17 is a diagrammatic view of still another modification.
In all of the views, like parts are desig nated by the same reference characters.
I will describe my invention as embodied in the structures illustrated. It is to be understood that these structures are merely illustrative, and that obvious modifications may be made.
Referring to Figs. 1 to 5 inclusive, the feed rollers 1, 1, shown as located at the right of the machine, first feed the sheets, taking them from the pile or from the continuous feeder. The sheets are fed to the rollers by the usual combing rollers. These feed rollers are positively driven, and the upper roller is elastically engaged with the lower roller by the ordinary spring arrange ment, as shown. To the left of the feed rollers are shown the upper intermittent feed roller and the lower intermittent feed roller 3. To the extreme left are shown the feed table rollers 4, 4. These rollers are" preferably the same size as the rollers 1, 1. The upper roller engages with the lower roller by the usual spring arrangement, as
shown. These rollers are rotated positivelyat the same rate of speed as the rollers 1, 1.
The rollers 1, 1, and 4, 4, rotate at the nor- 5, is shown at the extreme right. The sheets are taken oil' and fed to the rollers 1, 1,. by the usual combing roller (3. In the same view, tothe extreme left, is shown the printing couple 7, which comprises the impression cylinder 8 and type cylinder 9, with the usual inking rollers 10. T heimpression cylinder carries the usual gripper 11, which actuated by cam mechanism in the usual manner, so as to grip the front edge of the sheet which passes through the feed table rollers 1, -l, and along the feed table 12.
13 are the usual tapes.
14 is the gage. This gage not fixed but is movable. It is carried by the roller This gage, as shown in Fig. 1, is preferably made in a plurality of sections, so that it will be presented to thefront edge of the sheet through the openings in the table. The tapes 13 are supported upon the tape rollers 15. Suitable tension is imparted to them by the jockeypullcys 16 (see Fig.
17 represents the table having openings fo'allowing the feed tapes and the feed rollers to engage with the sheets. The edges of the sheets are retained in position by means of the guides 18, carried by suitable supports 19.
The roller 3 is carried upon a shaft 20. This roller is in several sections, so that it will engage with substantially the entire width of the sheet. The shaft 20 is rotated positively by mechanism which will be (lLr scribed later. I provide mechanism so that the rollers 3 are rotated preferably one revolution to feed each sheet. The gage, which is carried by the roller, is so supported that its speed in relation to the movement of the periphery of the roller will be retarded during the period of time immediately pre ceding and immediately following the en gagement of the front edge of the sheet with it. This produces whatl term a relative retarded movement of the gage, and compensates for the irregularities of feed made by the feeding rollers 1, 1, and tapes 13. larities in the feeding mechanism. The relative retardation can be attained by either retarding the. gage to a speed below normal, or by accelerating the sheets to a speed above normal, or both combined, as will be described. The roller is made with a portion of its periphery of greater diameter than the other portion (see Figs. 8, 5)
and 10); this 'a-ised portion being indicated by the numeral 40. This enlarged part of the roller engages with the upper roller 2.
' The unenlarged portion of the roller will not engage with the upper roller 2, owing to its being of less radius than the distance from its center to the periphery of the up per roller, and, consequently, the sheet will be pinched between the two rollers only when the enlarged part of the lower roller It also compensates for other irreguis in engagement with the; upper roller. The
gage is located on the portion of the lower roller ofsmaller diameter '(see Fig. 8)
chosen for illustration is so supportedthat" to the'movement of the roller. The devices j "o f'the lowerroller with it. t The gage is sup.-
mediately in advance of theportion of larger d ameter. 1 This; gage in the embodiment it may be swung in relation to the roller so that its movement willbe retarded relative.
for securing. this movement are illustrated best in Figs. 1, 2, 3, 4, 8, 9 and110.- 'These deVicescompnse means for rotating the,
'.*roller'shaft, and-means for swinging thegage upon 'its support For rotating the. lower roller I employ a spur gear 21, con--.. neotedto-and turning the'shaft 20. This shaft, as already stated, carries'the section's ported uponfa shaft 22, which is mounted in-s'uita'ble bearings 'in the sections of the roller 3 and is also mounted" in the spur gear. 21.1.. On the shaft 22 is a crank 23, and.
on this cia r1lg23 is a crank pin 24. This F crank pin mayc'arryv a roller,v as shown, for Ireducingjfriction The crankpin engages in a 25. This .cam 25 is so supported-'- that it will not turn, preferably by being secured to the frame 26 of :the machine. For the purpose of rotating the spur gear 21 a lay shaft 27 is provided with suitable gearing, whichIwill later describe,- for ro-' tating it. The operationgof the gage is best: shown in Figs. 3, 4, 8, 9 and ,10. As the spur gear 2l is rotated, thecrank'23 will engage with the cam 251. -.This is so shaped that the shaft 22 which carries the gage will be turned in its bearings sothatthe gage will be moved duringv a portion 0finto contact with it by means of the tapes 13; Fig. 9 represents the position of the gage just as the high part 40 of the lower roller comes in contact with the upper roller .2and pinches the sheet between the two rollers so that itwill be positively fed. During the movement from the position shown in Fig. 8 to that shown in Fig. 9,.the gage has been turned uponits supportingshaft in the,
direction oppositeto the direction of travel of the periphery of the roller, consequent-1y,

speed of the sheet after it has been brought into contact with the gage and is being driven forward by engagement of the high portion of the lowerjroller thei upper I 1' roller, as has been v 1e'sfe1:ibed-, I provide means for increasing; the'speed of the lower ..'roller after the high part' lO comes in cons tact with the .upperproller; 2.. Thisis so that the sheet may' then be .fed' at normal speed, wh'enit reachesthefeed table rollers 4,4, and be advanced or f retarded relative to a point on such rollers 4,4, ;I prefer to combine with this mechanism, nech-b {smwhich can be controlled as to the degre of acceleration, so that the sheet may be fed the-feed table r'ollers 4, 4, either in advan irregularities in location of the plates upon the type cylinder, -or provide for atmos= or behind a fixed point, to accommodate the '7 i so pheric conditions which may produce anac; t' I eeleration or retardation in the feed. This mechanism is so arranged that it may beadjusted' by the operator while (the machine is running. Some or all of thejdevices (which I will now describemay be utilized.
Referring to Figs. 1 and'2, the lay shaft gears 28, and.alsolbevelgears'from the main driving shaft 29. Thismai'h driving shaft 27 is turned at. xiormalsPeed by means of '29 carries bevel 'gearswhich rotate the shafts of the rollers 1, l and l, 4', at normal'speed. The lay shaft 27 carries a spur gear 30,
which. is'loosely mounted upon it. a The =shaft'27 has fixed upon it a toothed sector;
carries a toothed sector 33,- which is in engagement with the othertoothed sector 31. The shaft '32 carries a crank 34,. which has a 111 35. This pin may beprovided with a 31.1 The spur gear'30 carries bearings which "silp-por't a short shaft 32. This short shaft roller, as shown, for reducing friction.- The pin'35 engages with the cam- 736'. This cam 36 is supported upon a lug concentric with the shaft 27, and is free torotatethereon.
. The position of the cam is adjusted-while the machine is in operation, by devices best shown in, Fig. 2. These, devices comprise a worm teeth 37 on the camya nd these worm teeth ngage with a worm 38 mountedin suitabl 'rbearings in the frame 26. The worm,is"""otated by suitable devices,"as by mean and wheeL3'9. By rotating this hand ,Ethe rotary position of the cam 36* may one position, the rotation of the shaft 27 will carry with it the toothed sector '31; This toothed. sector will carry with it the toothed sector 23, and, throughthe agency {of the shaft 132, will rotate the'spurgean30.
erethe cam 36 simply a'groove of con- H r 115 1 ji be adjusted ,within' the necessary limits. The efl'ectof this mechanism is as afollows :'Assuming the cam 36 to be fixed in slower than the normal rate of speed of the.
shaft 27. This cam 36 is so configured that the acceleration of the spur gear 30, and consequently, the intermeshing spur gear '21,
will begin only after the high part 40 of the gauge roller 3 is in contact with the upper gauge roller 2, and thesheet is pinched between the two rollers. From this time until the sheet is released from engagement with the rollers 2 and 3, its speed will be acceler' ated; the degree of acceleration depending upon the angular position of the cam 36 which is adjusted by means of the hand wheel 39. It is apparent that this can be done while the machine is running, consequently, the operator can adjust the degree 10f acceleration, which will depend upon the character of the work, which may vary from time to time! According to all oftlie mechanism described, it is apparent that the sheet will first be brought into contact with the gage, which will be retarded in its movement in relation to the other moving parts of the feeder, so .that any irregularities in feed caused by the feed rollersl, 1, or any irregularlties in the shape or position of the sheet,
' will be taken'care of {for example, -should the sheetbe not exactly square to the gages, the tapes 13 which move-at normal speed, will bring the sheet into accurate engagement with the gages before the sheet is grippedbetween the high part of the lower roller 3 and the upper roller 2. Itis also apparent, from the before-described mechanism, that the retardation of 'the sheet caused by the relative backward movement of the gage, will be compensated for by the momentarily lncreased speed of rotation of the rollers2 and 3, so that, when the sheet leaves the engagement of the rollers, it will be moving at normal speed. It is also apparcut that by adjusting the position of the cam 36, the time at which the sheet is brought under the control of the nipping rollers 4, 4 may be retarded or advanced and consequently, the sheet can be made to accommodate itself to the different positions ofthe plates upon the printing roller and will also accommodate varying conditions or requirements of sheets which may occur during the operation of the machine. This latter adjustment is forthe purpose of delivering the gaged leading edge of the sheetto the nipping rolls 4, 4 at the proper time/so that it m y be ed t9 the printing Couple in pr p r registry with the plate carried by the type cylinder. This plate may vary somewhat in itsposition on the cylinder and the sheet must be delivered to it sooner or later as the case may be. h
TlIGJHOCllfiCfltlOD shown in Fig. employs a continuous feeder 41, having a higher supply table 42, and the usual combing roller 6.
It is to be understood, however, that the character of feeder is immaterial, as the con tinuous feeder may be used in connection with the mechanism shown in Fig. 6, while the pile' feeder may be used in connection with the mechanism shown in Fig. 7. As a matter of fact, these two forms of feeders are illustrated simply to show the application of the invention, and any form of feeder may be employed for feeding the sheets to plished by mounting the cam 25 in bearings so that it is rotated by suitable gearing at one-half the speed of the roller. The mechanism is shown diagrammatically in Fig. 7.
The spur gear 21 is rotated from the spur gear 30 by means of an intermediate spur gear 43. i
The cam is providedwith a spur gear -14, which is rotated from the spur gear 30 by" means of an intermediate spur gear 45. As the cam, therefore, turns at one halfthe speed of the roller, it will entirely depress the gage below the periphery of the roller, on the alternate revolutions, as shown in Fig. 13. It will, however, impart the twisting movement to the gage, to secure retardation as previously described, when the gage is in contact with the front edge of the sheet, as shown in Figs. 11 andvl2. The same mechanism for accelerating the speed of rotation of the spur gear 30, as described in connection with Figs. 1 to 5 inclusive, is used upon this em bodiment of the invention, but is not illustrated. Instead of the high portion 40, of the lower roller 3, a cam 49 is provided for moving the upper roller 2 away from the lower roller, when the gage is passing immediately under the upper roller;
The retarding efi'ect of the sheet in relation to the gage may be accomplished by other devices than those illustrated.
Fig. 14 shows diagrammatically a structure where the feed rollers are made larger, so that the feed to the gage will be above normal speed. These are indicated by'the c ers 4 and a e a g d to have a their than normal. The gagewhich isshown in'Eig. 114- 'has no relative movement-m relation tofthe roller, consequently, thesheetE"-is-'fed to the gage at a speed above normal.
