The expiring butt will nowbe in its properlocation for the splicing operation," as this position is automatically placed when the new roll 'fiil 'in the opposite spindle position is placed in the right location to the brush E02.

- At the extreme upper end 'of the side fram'es and .IeJis located a shaft I03. This shaft-[supports the paster arms H34 whichare'keyed thereto. The shaft swivels in brackets I89, one at each end,jwhich are securelyifa'stened to the side" frames land I The pasting mechanism iscmoved to operative and inoperative positions by a lever liliwhich is v keyed to the shaft I03 and located outside of the j c bracket Hi9 onth'eworin'gear' side ofthe reel.-

This lever engages a segment 'l 136 which. fastens" 1 toithe side frame '11 and is so a'rrangedj thata spring seated lock pin Hll in the handle ms of q 7 the lever' may lock the lever inany required posi tion; This,- of course, isthein'eans for locating the pastel arm: I04 which inFig. 1 is shownlin pastingposition. r The brushlfl is held in a 'brush'holder IIO.- The brush holder is in the shape of a lever which pivots with .a. shaft III to which it is securely clamped. The shaft III swivels in brackets] I2 which aresecured to the pastor-arms I64. The brush )2 is urgedby springs 'II3. towardsthe fresh roll but is kept from springing ahead by a pawlI I4 whichpivots on a'stud H5 on the brush or paster arm I04. The pawlI I4'is1cperatedbya solenoid I I6, mounted on a shelf I I1 ofpaster. arm I84, and is controlled by a push button, as will be. described'later. After the brush'j-has been. oper-.- ated by pushing thebutton it isonly required to move the brush arm I04 back. to inoperativeposi .tionand the brush will be automatically-reset by;

Placed at the lower end-of the brush arms IE4 is located the knife I25which'is ShOWiI/ill Fig. 5, in operative position. It is guarded by' a guard I26 which is fastened to a. toe I21 on' the brush afrnfIM." The knife is held'ina holder I28 secured to a shaft I29 which is 'oscillatably sup portedin brackets I32 pnthe pastor arms H54;

On this shaft arelccated'the two torsion springs If!!! of which'cne end of each:;is fastened to'a' operation it will be automatically. reset when thebi'u'shxa'rin IBl'i's brought to inoperative positioni,

A crank arm [38 is placed on the end of the" knife support shaft I 29. This crank is pivotallyconhected'tora rod I39 which slides through a poppet I 4! mounted on a projection l ififof thebracket I05. when. the'brush arm is moved from one position to another. there willdevelop a crank actionbetween the brush arm and the fixed center of the poppet I4I.' This motion will-be transferred: by the rod I39 to the lever I38,- thereby. resetting "the knife in inoperative position.

A tube I42 acts asia brace between tlietwo arms I84. It also'acts ass-bar for the paper to slide on When-the paper is running from the butt in pasting position; 1 i

The electrical equipment and the wiring dia-: gram operate as followsz' P Referring particularly to Fig. 10; lines L-TI and L-2, represent any sources of electrical power. The usual-.sWitchfiMS and fuseshtd are: provided. -A lineiI45 runsto one side of a push button I 46 which may be. conveniently located on the frame of the machine. The other side of the push button 146. is connected to a-line lfi-i' which runs'to contacts in said selector switch In this manner a selection is made ofth e par-- ticular spindle which carriesrthe freshweb roll.

A line Mg runs to ;a brush ll9 which is shown;

It will be'understood readily that? the high part of the cam connects the others splice. I 7

particularly in Figs. 10' and '8.- This, when the switchfl lii' is closed and'pushbutton I46'is closed,

.will feed one side of the line to a center commutator ringISii. An insulated segment I5I is contacts I41 and'-I53 ,-thereby establishing a.

hold-in; circuit for the brush solenoid. When the brush. I82 moves forward to make the splice, the cam-I on the shaft II I, as best shownin Figs. i and-b', operatesa roller I56? 'on a switch I55, the. latter being carried by the bracket on the" brush arm and thereby, permits contacts to beclosed in this switch. This closingof contacts in the switch I56 connects line I54, which-is one side of the power line, to a knife solenoid I38,

the other side of which is connected by the line E5! to abrush I58 which cooperates witha contact segment I59 which is connected with the center ring I50 and then through the brush I49e,

line I49,"switch I48, line I41, push button M6 and line I45to the-other side of the line. This energizes'the knife solenoid andpermits theknifc 525 to sever the web'in amanner previously c1escribed. Italso' closes contacts I4I and 151' and thereby establishes a holdin circuit forthe. knife solenoid. When the push buttonI45 is opened by the operator releasingthe power the two solenoids IIB and-I36 are disconnected and these solenoids are deenergized;

It is evident that, whenthe'switch I48 operates to disconnectitheflower contacts'and connect the upper contacts, the commutator rings 5I serving the other spindle of the'reel, are connected,; thus the fresh roll may be first on one I spindle and then the other, it being automatirelation to gears I5, I8 and I 9.. By placing a suitable marker on-the-gear I9 the fresh pasteon the new roll Ii9 may be applied with reference to that marker. and thereby insure proper-operation of-the brush and knife to, make a successful The-splicing operation will now be explained.

As formerly explained, when the one paper roll'is in its running oil position, the opposite paper roll sockets are in the proper position for loading the reel. The expired butt will now be removed and a new roll be put in its place. In approximate line with a mark on the gear I9 the outside sheet Will now ,be. cut in the shape of saw teeth forming preferably: two corners Each of these cornerswill now be pasted to-the surface of thepaper roll by a paster'tab. This tab is a piece of paper that has been weakenedin the paper roll-except for ajportion inthe center of the roll which must be kept free of paste to make a clean path for tie belt 5'5 and rollSl;

The expiring butt will now be watched. When it is considered small enough to prepare for splicing, the hand wheel 5 3 will be revolved caus ing the new roll to move in an anti-clockwise direction unitil a predetermined mark on the frame is reached. This is the proper place for splicing if the splicing position is reached. At this time the arm Ifi i will be moved. to the right as far as it will go and locked, causing the brush arm I04 to be held in its proper position for splicing. Fig. 1 shows the brusharm in this position. The space between the brush and the roll will now be approximately one-half inch. The belt arm 14 has all this time been kept in its upper position with the belt 61 out of contact with the roll. It will now be lowered by moving the operating lever H to the left, bringing the belt 6! into contact with the surface of the roll. Since the belt is driven from thepress at paper speed, it will now start the roll spinning at a surface speed equal to the printing speed.

When the paster is to be made it is then necessary only to make an electric contact by push- In a websupporting ,reel,'the combination 7 of a central shaft, double arm paper roll spiders each spindle being supported by bearings in both I spiders, means on each spider for adjusting one spindle only longitudinally, braking means for ing the push button M6. This will operate the solenoid H6 which will make the brush force, the paper from the butt against the surface of the new roll. The paste on the end of the outside sheet of the new roll will stick to the paper coming l3. The lever 11 will be moved to the right as far as it will go and locked, raising the belt 6'! out of contact with the roll. \r l Having thus described my invention andthe advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
