To all whom t may concern.'

Be it known that I, TALBOT C. DEXTER, of Fulton, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Paper Registering Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to mechanisms em- 1o ployed for registering printed sheets of paper preparatory to folding the same into .book form.

In practice it has been found that frequently the blank margins of the printed sheet vary I5 in width, especially when the sheet has been printed on what is known as a web or rotary printing-press that takes the sheet from the roll. In'severing the sheets the cutting may be perfectly parallel to the printing; but zo it often occurs that the cutting at one end or side of the sheet is nearer to the printing than the opposite end or side, and consequently the two margins differ in width, and at other tim es the cutting may be slightly oblique to the printing7 and in that case the margins are wider at one end t-han at the opposite end. In consequence of these variations of the margins it is impossible to accurately register the sheet by bringing the edge of the sheet 3o in contact with gages orguides. To obviate this difficulty the .so-called point-feed has been resorted to, in which the sheet is perforated at predetermined locations during the passage of the sheet through the printing- 3 5 press and is then placed by hand upon the folding-machine and adjusted thereon in such a position as to cause the upwardly-proj ectin g points on said machine to enter the perforations of the sheet. The perforations being 4o always in the same positions in the successive sheets, and the aforesaid points being permanently located on the folding-machine, causes the sheets to be perfectly registered. Said method of registering the sheet is, however, 4 5 very sion,T and tedious, and therefore the process of folding the sheets is very much delayed.

It is this defect which is effectually obviated by my present invention, which consists es- 5o sentially of a registering apparatus provided wiih a gravitating pin or other suitable catch carried back and forth over the plane of thc paper conveyed into the machine automatically, and in the movement of said pin or catch in one direction it engages the perforation in the paper, and thereby moves the said paper to its registering position; and the invention also consists in the combination, with said gravitating pin or catch,of a bearing connected thereto and riding on the sheet to as- 6o sist the movement thereof and guard against the tearing of the sheet by the engagement of the pin or catch; and the invention furthermore consists in other auxiliary devices employed in connection with the aforesaid pin or catch, as hereinafter more fully described, and speciiically set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a paper-folding machine equipped with my improved registering ap- 7o paratus. Fig. 2 is a plan view of the same. Figs. 3 and 4 are enlarged vertical longitudinal sections respectively on line X X in Fig.

2 and showing the registering apparatus in different operative positions. Fig. 5 is an en- 7 5- larged vertical transverse section on line Y Y in Fig. 2. Fig. 6 is an enlarged detached plan view of the gage-supporting bar, and Figs. 7 and S are enlarged side views and partly vertical longitudinal sectional views of modiii- 8o cations of the paper-engaging catch or pin and its carrier.

Similar letters of reference indicate corresponding parts.

A denotes the main supporting-frame of the papenfolding machine. B B designate the folding-rollers, C the folding-blade, and c a the tapes which convey the paper from the feed-board rectilinearly to the foldingmachine. All of said parts are arranged to 9o operate in the usual and well-known manner.

The paper to be folded is perforated or provided with short slits at predetermined points during its passage through the printing-press, as hereinbefore stated.

The purpose of my invention is to register the irregularly margined paper automatically, accurately, and rapidly after it has been delivered to the folding-machine by the aforesaid tapes, and thus save time and labor in 10o the operation of folding the paper. This I accomplish'by means of a gravitating pin or analogous suitable catch D, which is supported on a carrier h riding on horizontal guides c c over the paper-supporting bars or plates d d. I preferably employ for said catch a vertical pin suspended from the free end of a lever e pivoted to said carrier. Said pin may be formed separate from the lever and provided with a collar f above the lever to permit the said lever to lift the pin, as hereinafter described. The lower end of said pin passes through a vertical guide either in or on the carrier, and is thus sustained in a vertical position while operating on the sheet to be registered, or said pin may be formed integral with the lever, as represented in Fig. S of the drawings.

The carrier is moved back and forth by a reciprocating rod R, which is connected to the carrier, with a lost motion between them to allow said rod to lift the lever e in the forward movement of the rod and drop said lever in the reverse movement of the rod. This lost motion of the rod and its action on the lever may be obtained in various ways, two of which I have illustrated in the annexed drawings. In one case the lever e is of the shape of an elbow or bell crank, one arm of which is under the collar f of the pin D and the other arm has connected to it the reciprocating rod R and is limited in its movement by a stop on the carrier. In the forward movement of the rod it :first lifts the lever c and then moves the carrier. In the other case the lever c is pivoted to an upwardly-projeeting ear on the carrier b and is provided with a beveled or inclined downward projection c. The end of the rod R is bifurcated or slotted longitiuli1'1ally,as shown by the longitudinal sectional views of said rod in Figs. 7 and Sof the drawings. Through the slot of said rod projects the ear to which the lever e is pivoted. In the cnd of this same slot is a roller pivoted tothe rod R and riding on the carriere in front of the ear of the carrier. The aforesaid slot is of sufiicient length to allow the rod R to slide a short distance longitudinally without causing either the closed end of the slot or the roller in the opposite end of the slot to push or draw the carrierb along with the rod. In

' the forward movement of said rod the roller in the end thereof passes under the beveled downward projection c of the lever c, and thereby pries up said lever and causes the same to lift the pin D. In the retrograde movement of the rod R it draws its roller from under the projection e, and thereby causes the pin D to drop onto the paper, and then the said rollercomes in contact with the upwardly-projecting ear of the carrier D and draws said carrier back with the rod R.

In order to insure the lifting of the lever c as aforesaid, I mount on the guides c c friction-plates h 7L secured adjustably thereto by means of screws h 7L and bearing on the carrier b so as to resist the movement thereof sufficiently to allow the rod R to move forward and lift the lever.

The rod may be reciprocated by any suitable mechanisn actuated by the gearing of the folding-machine. It is represented. of the form of a lever l, fulcrumed on the frame A, and having its upper end connected tothe rod R and its lower end bearing on a rotary cam I.

To allow the described registering apparatus to be adjusted for operating on sheets of different sizes, I connect the lever l to the rod R, adjustable longitudinally, which may be accomplished by means of the couplingpin of said parts passing through a longitudinal slot yL' in the rod.

In order to guard against the tearing of the paper in the operation of the pin or catch D engaging the perforation in the sheet and drawingthe sheet to its registering position, I attach to the lower end of the pin a disk `n, of rubber or other suitable material, to form a proper bearing by which the pin rides on the paper during the retrograde movement of the carrier b.

Directly under the plane of the sheet to be registered is a sheet-supporting bar d, which is supported at one end upon a roller r and connected at the opposite end to a lever l) pivoted to the frame and actuated by a rotary cam N, which imparts an intermittent oseillatory motion to the lever and a corresponding reciprocating motion tothe said supporting-bar. rIhis bar is provided with a longitudinal slot d for the passage of the lower end of the pin D. Upon this bar is adjustably mounted the front guide, p, against which the sheet is drawn by the movement of the pin D when engaged with the perforation of the sheet. rIhe movement of the lever L is so timed as to cause the front guide, p, to recede an d prevent the buckling of the sheet between the gage and pin. The adjustability of the front guide, p, upon the bar (l is desirable to allow said front guide to be shifted in its position to correspond to the width of the sheet to be registered.

To completely register a sheet requires three of the aforesaid sheet-shifting mechanisms, two of which are arranged at the end of the folding-machine te register the sheet endwise, and one at the side of the machine, as shown in Fig. 2 of the drawings, to register the sheet laterally. All of said mechanisms are substantially alike with a slight modification of the forms of the levers which move the paper-supporting bars (l. In the endregistering mechanism the lever L is pivoted to the frame beneath the cam N, as shown in Fig. i of the drawings, while the lever Il, which moves the bar d, with its side guide, Vp', is pivoted to the frame above its actuatingcam N. The cam I (shown in Fig. 5) operates the lever l in the same manner as the :am I in Figs. l and 1.

The operation of the described registering lOO apparatus is as follows: The paper is delivered to the folding-machine by the traveling tapes in the usual manner and arrested in said movement by the advance edge of the paper coming in contact with the front guide, p. The pins D D of the registering mechanisms at the vend of the machine are in the meantime sustained in elevated positions. Assoon as the paper has come to a stop the registering mechanism at the side of the machine is actuated to carry its pin D in an elevated position in a lateral direction over the paper. In the subsequent retrograde movement of the carrier b the pin D is allowed to drop onto the paper, and in traversing the same it enters the side registering slit in the paper and by the resultant engagement of the pin with the paper the paper is drawn laterally to the side guide, p', by the movement of the carrier. The end guide, p, recedes at about the same time the aforesaid pin D enters the slit to allow the paper to be shifted, as aforesaid, more freely and without liability of buckling the paper between said pin and end guide. The two registering mechanisms at the end ofthe machine are then set in motion to be operated in the same manner as the side'registering mechanism. In the operation of the two end registering mechanisms the registering of the paper is completed, irrespective of any irregularities inthe margins of the sheet, inasmuch as the two carriers are located at opposite sides of the central lines of the paper-conveying tapes and travel parallel therewith, and the pins D D mounted on said carriers enter two slits which are at right angles to the line of movement of the pins and made accurately in the sheet, K

as hereinbefore stated, and in case the sheet is out of alignment, so as to present the slits different distances from thenend guide, p, the pin which engages the farthest slit draws one side of the sheet forward until the two slits are equidistant from the aforesaid guide, and the sheet is drawn along rectilinearly by the two pins entered into the two slits. Fig. 3 of the drawings shows one of the end registering mechanisms in positon to allow the sheet to be carried to the end guide, p, by the traveling tapes in the usual manner, and Fig. 4 shows the end guide receded and the sheet drawn longitudinally to its register by the pin D. movement of the'sheet it is carried beyond and out of contact with the usual tape-roller and drop-roller at the-feedend of the machine.

It will be readily understood that in view of the fact that the slits or perforations are made in the paper during the process of printing the same and by cutters maintained uniformly in their position in relation to the printed portions of the sheet, and the registering of the machine is controlled by the slits or perforations, the variations in the width of the margins of the printed sheets have no effect on the registering of the sheets. Hence by my present invention the registering of In the latter part of the longitudinal the sheets is accomplished automatically in a most accurate and expeditious manner.
