PAPER-REGISTERING MECHANISM.

SPECIFICATION forming part of LettersPatent No. 652,169 dated June 19, 1900.- Application filed October 24, 1899. Serial No. 784,623. (No model.)

To all whom it may concern:

Be it known that I, TALBOT O. DEXTER, of Pearl River, in the county of Rockland, in the State of New York, have invented newand useful Improvements in Paper-Registering Mechanism, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to an improvement in mechanisms employedin connection with paper-folding machines and analogous machines for the purpose of automatically and accurately registering the sheets of paper preparatory to folding or otherwise operating on the same; and the invention has special reference to the class of paper-registering mechanisms in which the registering instrument proper is equipped with a tongue or point adapted to enter a slit provided in the sheet for that purpose.

The object of my present invention is to provide more efficient means for opening the slit in the paper to facilitate the entrance of the registering-pointinto said slit; and to that end the invention consists in the novel construction and combination of the component parts of the registering mechanism, as hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure 1 is a vertical longitudinal section of a portion of a paper-folding machine equipped with my improved paper-registerin g mechanism. Fig. 2 is a reduced plan View. Fig. 3 is an enlarged plan view of the registering mechanism. Fig. 4 is an enlarged vertical transverse section on line Y Y in Fig. 1. Fig. 5 is an enlarged detached plan view of the slit-opening bridge and the bed which imparts a further advance movement to the sheet to be registered; and Fig. 6 is a vertical longitudinal section of a portion of a folding-machine, illustrating a modification of the paper-registering mechanism.

Referring to the drawings, A represents the main frame of the paper-folding machine.

B ]3 denote the usual folding-rollers.

a a are the traveling tapes,wl1ich convey the sheets of paper into the machine, and 1 1 are the longitudinal bars, which support the por tion of the sheet beyond the folding-rollers;

O designates the folding-blad e, which tucks traveling tapes.

i the aforesaid blade 0.

the sheet between said folding-rollers, and D is the feed-roller, upon which the tapes a a run, over which roller are located the droprollers D D, which press the sheet upon the All of said parts are arranged to operate in the usual and well-known manner.

E represents the front stop or end gage, against which the advance edge of the sheet is brought when fed into the machine. Said gage is made to alternately move part way toward and from the folding-rollers B Bby' means of a rock-shaft F, having depending from it arms F F, the lower ends of which are connected to longitudinal bars G, upon which the aforesaid gage rides and is adjustably secured in its position by means of sore wrods b, passing through nuts 0 on the gage and journaled in brackets d, attached to the bars G. On the ends of the screw-rods b are secured worm-gears H, which mesh with cor responding gears H, secu red to a transverse shaft e, which is journaled in ears g 9, formed on the brackets d. The end of the shaft is provided with a hand-wheel h by which to turn it, and thereby turn the screw-rod b, which moves the gage E to the desired position in relation to the folding-rollers B B to accommodate sheets of different lengths. The rock-shaft F receives motion from a lever I, which is attached thereto, and isoscillated by means of a rotary cam I, secured to a shaft J, journaled on the main frame, which latter shaft receivesits motion, preferably from one of the folding-rollers B, either by a chain, belt, or gears, as indicated by dotted lines at as in Fig. 2 of the drawings, although the same may be operated otherwise. The aforesaid bars G ride-upon, rollers e' e', journaled on a transverse shaft j, supported in posts 7t is, mounted on the frame A.

The purpose of my improved paper-registering mechanism is to automatically and accurately adjust the sheet to bring'a predetermined line of folding directly over the bite of the folding-rollers B B before the sheet is introduced between said rollers by There being two registering instruments employed and located at opposite sides of the central line of travel of the sheet of paper, as is well known, each of these registering instruments is operated by the following mechanism,to wit: A bracket A is mounted on a stationary cross-bar B, preferably dovetail-shaped in cross-section and extended across the machine and supported on the aforesaid posts 70 70 on the frame A. From said bracket extends rearwardly or toward the folding-rollers a hori zontal bar 0, which is shaped dovetail in cross-section or otherwise formed with a longitudinal guide and supported at one end on said bracket and at the opposite end on across-bar E, mounted on suitably-supported posts on m. To the side of the bar 0 are pivoted the bell-crank levers n n, and to corresponding arms of these levers is pivotally connected a horizontal bar G. The other arms of the levers n n are connected by means of a rod 0, which causes said levers to operate in unison and to raise and lower the bar G in parallel planes. One of the latter arms is extended in length and is connected, by means of a rod 19, to the upper end of an arm q, rigidly secured to a transverse rock-shaft 0, whereby saidlevers are oscillated. The shaft 1" is journaled at its ends to stationary brackets J J, mounted on the frame A, and passes through the aforesaid brackets A and receives its motion from a lever 8, depending from said shaft and oscillated by means of a rotary cam A secured to the aforesaid shaft J. The rod 19 is screwthreaded at its connection with the arm q and is provided with nuts t t at opposite sides of the arm, whereby the distance between the points of connection of the rod 10 can be varied to cause the levers n n to carry the bar G at the desired elevation above the plane of the paper-supporting bars bb. A vertical plate a is formed*with a horizontal projection 19, and through this projection passes a set-screw d, which bears upon the rib 0, formed on the side of the bar G, and thereby supports the plate a in a suspended and vertically-adjustable position. To the lower end of said plate is attached the tongue 6', which by engagement with a slit in the paper registers said paper. By the aforesaid vertical adjustment of the plate a the tongue 6 is made to bear with the requisite pressure upon the paper to effect the aforesaid register. The tongue 6 projects rearwardly from the plate a and is located in the path of the slitted portion of the sheet, so as to enter the slit, as hereinafter more fully described. The plate a slides in a vertical guide f, formed in a block g, mounted longitudinally adjustable on the bar 0', which adjustment iseifected by means of a screw-rod h, journaled in a block i, adjustably secured to the bar 0 by a set-screw. Said rod 72. passes through a screw-threaded ear j, formed on the block g. Said adjustment is provided for the purpose of setting the tongue-e in the required position according to the location of the slits provided in the sheets.

1 13 represents a bed consisting of a pad of rubber or other suitable material upon which a portion of the delivered sheet rests. Said bed is carried on alongitudinally-reciprocating plate a which receives its movement from the aforesaid gage E, to which it is secured, preferably by means of an L-shaped plate b clamped adjustably onto the plate a. by means of a bolt 0 passing through the horizontal portion of the plate 19 and through a longitudinal slot 3 in the plate a and attached to a washer 4E and provided with a nut 5 on its end. The plate a slides in longitudinal grooves or guides 01 11 provided in the edges of the bars 1 1. The bed B carried onthe plate a serves, with the aid of the sheet-depressor hereinafter described, to obtain a frictional hold on the sheet to impart a secondary advance movement to the sheet after the sheet has been arrested by the gage E, as will be shortly more fully explained.

d is a vertically-disposed coil-spring which is connected at its ends to two pins c f projecting horizontally from the upper portion of the plate a and lower portion of the block g, respectively. Said spring serves to impart 'a downward pressure to the plate at, whose downward movement in the guide f is limited by the aforesaid set-screw d. Said sheet-depressor consists of a roller 9 located back of the aforesaid registering-tongue e and journaled on a bracket 7L2, secured vertically adjustable to the plate a by means of the attaching-screw 71 passing through a vertical slotj in the plate a.

In front of the tongue 6 is located a sheetlifting bridge k which is secured longitudinally adjustable to the plate a by means of a bolt Z passing through a slot 121 in said plate and engaging the bridge. Said bridge being in the path of the slitted portion of the sheet serves, in conjunction with the depressingroller 9 to open the slit for the entrance of the tongue 6.

The aforesaid bracket A is adjustable lengthwise of the cross-bar B to accommodate to the width of the sheet the sheet-registering devices carried on said bracket, which adjustment is effected by means of a screwrod 0 which is parallel to the bar B and journaled in suitable bearings on the frame A and passes through a nut g formed on the bracket A. The rod 0 is provided with a hand-wheel o I The operation of my improved paper-registering mechanism is as follows: The sheet of paper is conveyed into the folding-machine by the tapes a a, while the bar G, carrying the registering instrument and depressingroller 9 is in its elevated position, whereby the sheet is brought with its advance edge against the gage E and is thereby arrested, said gage being in its position nearest the foldingrollers B B. The bar G is then dropped, whereby the tongue e of the instrument is made to bear slightly upon the sheet and the roller 9 to bear firmly thereon to press the sheet into frictional contact with the bed B Immediately after the tongue 6 and roller 9 have been brought into contact with the sheet the gage E is moved forward, thereby shifting the bed 15*, which by the aforesaid frictional contact with the sheet imparts a secondar advance movement to the sheet. In this movement the slitted portion of the sheet is drawn onto the top of the bridge k which opens the slit and facilitates the entrance of the tongue e. The rear edge of the slit then coming in contact with the heel of the aforesaid tongue arrests the further advance movement of the sheet and accurately registers the same. The bar G is then raised, whereby the tongue e lifts the slitted portion of the sheet to prevent the slit from being caught on the bridge and tearing the same when the sheet is Withdrawn from the tapes a (L by the folding-blade C, which descends and tucks the sheet between the folding-rollers B B in the usual and wellknown manner. After the sheet has been withdrawn the gage E recedes, and the registering instrument and depressing-roller being in their elevated position the next incoming sheet is allowed to pass under said instrument and roller to be registered in the manner described.

In some cases Iprefer to support the sheetdepressing roller g independent of the registering instrument, as illustrated in Fig. 6 of the drawings, in which said roller is pivoted to vertical plate 7*, which slides vertically in a block 3 mounted longitudinally adjustable in the bar 0, which adjustment is effected by means of the aforesaid screw-threaded rod h, which engages a screw-threaded car 1 formed on the block .9 The plate r and block 8 are provided with horizontally-projecting pins n and 17 respectively, to which is connected a coil-spring 10 Said spring serves to impart a downward pressure to the plate 9*, the downward movement of which plate is limited by a set-screw .99
