To (tZZ "1071 0771, it may concern.-

Be it known that I, TALBOT O. DEXTER, a citizen of the United States, and a resident of Pearl River, in the cou'nty'of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registerin g Instruments, of whichthefollowing,taken in connection with the accompanying draw ings, is a full, clear, and exact description.

The objects of my present invention are primarily to provide a simple and eflicient instrument that shall be capable of registering the paperboth longitudinally and laterally, and, secondarily, to adapt said instrument to be used on a paper-folding machine in which the paper-delivering tapes are disposed parallel with the folding-rolls; and to that end the invention consists in the novel construction, combination, and arrangement of the mechanism for operating the paper-registering instrument and auxiliary devices connected therewith, as hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a paper-folding machine equipped with my improved paper-registerin g devices. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged vertical transverse section on line Y Y in Fig. 2, showing the registering instrument in position to allow the paper to be delivered under it. Fig. t is a further enlarged vertical transverse section of the registering instrument proper in position to register the paper, taken on line X X in Fig. 2. Fig. 5 is afront view of the same. Figs. 6 and '7 are transverse sections on lines V V and Z Z, respectively, in Fig. 5. Fig. 8 is a still further enlarged end elevation of the mechanisms for imparting motion to the registering instrument, and Fig. 9 is a transverse section of the longitudinally-movable bar which carries the registering instrument and means for transmitting motion to said bar.

Similar letters and figures of reference indicate corresponding parts.

A represents the main supporting-frame of a paper-folding machine comprising the folding-rolls B B, the blade 0, which tucks the paper to be folded into the bite of said rolls, the tapes a a, which deliver the paper into said machine, and the front stop D, which arrests the advance movement of the paper preparatory to its introduction into the folding-rolls. V I

In the machine here presented the paperdelivering tapes a ct are disposed parallel with the folding-rolls B B and receive longi: tudinal. movement from the usual feed-roll E E, from which they travel to suitable rollers a 0; on the opposite side of the machine.

F F are the usual drop-rollers, which are over the feed-roll E, to press the sheet into intimate contact with the feed-roll and cause the same to force the sheet onto the tapes a a, by which the sheet is carried along until arrested by contact with 'the front stop D.

In the subsequent operation of the blade 0 introducing the sheet between the folding; rolls B B said sheet is drawn transversely from the tops of the tapes a Before this introduction of the paper into the bite of the folding-rolls B B the sheet is required to be registered or adjusted to bring the required line of folding of the sheet in coincidence with the bite of the folding-rolls. To accomplish this in an efficient and accurate manner, I resort to the following construction, combination, and arrangement of parts, to wit:

Transversely over the tapes OtCt is disposed a longitudinallymovable bar G, sliding in suitable guides G G on the frame A. By mechanisms hereinafter described said bar receives intermittin g reciprocating motion. At opposite sides of the folding-rolls B B, I connect to the bar G brackets composed of shoes I) Z), receiving said bar through them and having depending from them arms 19 17 which carry the registering instruments hereinaf ter described. Said shoes are adapted to be shifted lengthwise of the bar and are clamped in their required positions by means of setscrews 17 19, passing through the shoes and engaging the bar. To permit the shoes to be accurately adjusted in their positions, I mount on the bar G hangers c c, which are likewise adapted to slide lengthwise of the bar and are clamped in position by means of set-screws c. The lower end of each of said hangers is formed with a nut or screw-threaded sleeve 0 through which passes the ad j usting-screw c, which is extended and passes through a nut 0 firmly attached to or integral with the shoe 1), as more clearly shown in Fig. 5 of the drawings. The said adj ustment of the bracket-shoe Z2 is effected by loosening the set-screws b b and c, and after the shoe 1) has been placed approximately in its required position'the setscrew 0' of the hanger c is tightened, so as to confine said hanger in its position. Then by turning the adjusting-screw 0 the shoe 1) is moved accurately to its required position and is then'fastened bytightening the set-screws Z) 1;. The aforesaid adjustment is required to support the resigteriug instrument in the path of the slit or perforation made in the paper for the purpose of registering it thereby. A second adjustment is required of the two bracketarms b b at opposite sides of the foldingrolls to arrest the advance movement of the sheet in such a position as to cause the required line of folding of the sheet in coincidence with the line of the bite of the foldingrolls. This adjustabilityisobtainedbytrans verse guides d on the undersides of the shoes I) and correspondiugly-shaped heads (1'' on the upper ends of the bracketarms Z1 Said bracket-arms are thus allowed to be shifted backward or forward parallel with the tapes and support the registering instruments in proper positions to cause them to arrest the forward movement of the sheet precisely in a position to bring the line of folding of the sheet in coincidence with the line of the bite of the folding-rolls. To permit convenient accurate adjustment of the said hanger-arms, I provide the heads (1 thereof with screwthreaded sockets e, parallel with the guides (I and engaged by the adjusting-screws e',which pass through rigid lips c on the shoes Z) and are prevented from moving longitudinally by collars 6 attached to the screws in front and rear of the said lips, as shown in Fig. 9 of the drawings. The hanger-arms b are each provided with a vertical guide f, on which is a slide g, to which is pivoted vertically an arm h, preferably by means of a post it, fastened to or integral with said arm and pivoted at its ends to the heads 9' g of the slide, as more readily seen by reference to Figs. 5, 6, and 7 of the drawings. To the lower or free end of the arm 7b is fastened the registering point or tongue 7L2, designed to enter into the slit or perforation in the paper to be registered. The: slide 9 receives the requisite intermitting vertical reciprocating motion by mechanism hereinafter described.

In a paper-folding machine having the delivering-tapes a a parallel with the foldingrolls B B it is necessary to sustain the arms h hof the registeringinstruments yieldingly toward the folding-rolls, so as to allow the paper to be withdrawn laterally out of engagement with the registering-points 7L2 7L2 without tearing the sheet, and for this purpose thesupporting-posts lb of the registering instruments are pivoted, as before described.

By means of stops t, secured to the slide g, and suitable springs i, holding the arms 7: in

contact with said stops, the registering in-' struments are held normally in position to engage the slits or perforations in the sheet passing under said instruments.

To facilitate the entrance of the registering-point 7L2 into the slit or perforation in the sheet to be registered, a suitable sheet-depressor, preferably of the form of a suitablyshaped spring-plate j, is attached to a supporting-bracket on the slide 9 to move vertically therewith.

The slide g receives intermitting reciprocating motion from a rock-shaft I, disposed transversely over the tapes a a and mounted in bearings onbrackets II II, secured to the frame A. Said rock-sha ft has extending from it arms I, the free ends of which are connected to the slides g by means of pitmen J. Said arms can be shifted lengthwise of the shaft to conform to the position of the brackets, which carry the hereinbefore-described registering instruments. By means of setscrews 7;, connected to the arms I and engaging the rock-shaft, said arms are retained in their adjusted positions. The rock-shaft is oscillated by means of a rotary cam K, on which rides a roller Z, pivotedto one of the arms of a bell-crank lever L, pivoted to a hanger Z on the frame A. To the other arm of the said bell-crank is connected an upwardly-extending rod L, which is guided vertically by means of a pin on, projecting from a stationary bracket m and passing through a vertical slot m in said rod. The upper end of the rod L is provided with a rigid laterally-projecting bifurcated head L the two prongs of which have projecting from opposing faces thereof tappets n and n, bearing, respectively, onto the top and bottom of a tongue 0, which projects radially from a collar o, fastened to the rock-shaft I, as shown more clearly in Fig. 8 of the drawings. The tappet n, which is subjected to the strain of lifting the slides g, with the registering instrument, by the arms I, attached to the rockshaft I, is made adjustable to compensate'for the wear of the points of contact of said tappet and tongue 0. For this purpose the tappet passes loosely through the prong of the head L and rests with its lower end upon the to of a set-screw o" inserted in a ro'ection,

c on the rod L.

One of the chief objects of my present invention is to register the paper laterally by the same instrument which registers said paper longitudinally. For this purpose I employ the longitudinally-movablo bar G, hereinbefore described, which bar receives properly-timedintermittingreciprocatingmotion preferably from the rock-shaft I, which is movable longitudinally and reciprocated by suitable actuating mechanism. To transmit said 'motion to the bar G, one of the bracket-shoes b has rigidly projecting from it a finger p, which is maintained in engagement with a circumferential groove 1) in the attaching-collar of the. arm I, as shown in Fig. 9 of the drawings. For imparting the required reciprocating motion to the shaft I, I prefer to employ a cam N, fastened to the shaft N, to which the cam K is attached. Upon the cam N rides a roller '2", pivoted to the free end of an arm 0, which is attached to the shaft q, mounted in bearings q q, secured to the frame A. A lever 0, attached to the shaft q, extends upward therefrom and is connected to the outer end of a rod 0", the inner endof which is pivotally connected to ahub projecting from a sleeve 1*, mounted on the shaft I and held in place by means of collars r adj ustably secured to the shaft at opposite ends of the sleeve.

To maintain the tappets n and n in contact with the tongue 0 during the reciprocating motion of the shaft 1, said tongue is elongated or distended in the direction'lengthwise of the shaft and is preferably provided with grooves or ways for the tappets.

In connection with the described registering instruments I employ the alternately ad vancing and receding gage or front stop D, similar to that shown in my Letters Patent No. 561,937, dated June 9, 1896. Said front stop rides upon bars 2 2, disposed at right angles to said front stop and supported at their inner ends upon rollers 3 3, pivoted to suitable stationary supports. The outer end of each of said bars has rigidly secured to it a bracket 4, in which is journaled a rod 5, having its inner end screw-threaded and passing through a nut 6, attached to the front stop D. By the turning of the two screwrods the said front stop is adjusted for different-sized paper to be registered and folded.

To turn the two screw-rods synchronously, I attach to each of them aworm-gear 7, which meshes with a corresponding gear 8, attached to a shaft 9, mounted in arms 10, formed on the brackets 4. A suitable crank or hand wheel 11 is attached to the end of said shaft for turning it. The outer end of each of the bars 2 2 is supported by an arm 12, fixed in a suspended position to a rock-shaft 13 and pivotally connected at its lower end to the bracket 2, as shown more particularly in Fig. 3 of the drawings. The rock-shaft 13 is actuated by a lever 14, fastened thereto andhaving 011 its free end rollers 15, engaging a rotary cam 16, which imparts oscillatory motion to said lever.

To facilitate the second advance movement of the paper during the receding of the front stop from its papenarresting position, I attach to said front stop suitable sheet-depressing devices, preferably of the form of springplates 3, attached to the free ends of arms '5, clamped onto the front stop and extending toward the registering instru men ts. The tension of the spring-plate may be made adjustable by a set-screw a, connected to the arm 11 and bearing upon the top of the spring-plate. Said sheet-depressing devices serve to increase the frictional hold of the tapes a a on the overlying sheet.

In the operation of the machine the registering instruments are held in elevated position to allow the incoming sheet to pass under them, and at the same time the front stop D is in its rearmost position to arrest the advance movement of the sheet before the slitted portions thereof are carried directly under the registering.instruments. Then said instruments descend and the front stop D is drawn forward, which latter causes the'sheet to receive a secondary advance movement, and in this movement the registering-points 72, enter into the slits in the sheet, and thereby register said sheet longitudinally. As soon as this is effected the longitudinallymovable bar G receives a reciprocating motion, and thereby causes the paper to be shifted laterally and registered in said direction by the entered registering-point 77. on the arm h, which is sustained by the stop 1'. The sheet .thus registered is then introduced into the bite of the folding-rolls B B, and in this operation the supporting-arms h of the registering-points k yield to the draft of the sheet and allows the same to be drawn out of engagement with the registeringpoints without danger of tearing the sheet.

What I claim as my invention is- 1. A combined longitudinally and laterally paper registering instrument provided with means for engaging a slit or perforation in the paper, and actuated to effect said engagement and thereby impart the first register to the paper, and to subsequently move laterally while engaged with the paper,and thereby shift the paper to its second register as set forth.
