To all whom it may concern: 1

- Be it known that I, TALBOT O. DEXTER, of Pearl River, in the county of Rockland,-in the State of New York, have invented new and useful Improvements in Paper-Registen. ing Mechanisms,of which the following,taken in connection with ings, is a full, clear, and exact description.

This invention relates to paper-registering devices employed on machines .designed to either fold or rule or otherwise operate on sheets of paper fed into themachine by trav- Heretofore such machines provided with sheet-registering attachments have been arranged to feed the successive sheets into the machine by means of traveling tapes or other feeding devices and temporarily arrest the sheets near registered position by means of a receding end gage, which then recedes to allow the tapes or feed ing devices to impart a secondary movement to the sheets in the same direction to be arrested by the sheet-registering instruments when the sheets reach registered position.

The object of the invention is to provide eflicient and reliable means for properly reg-v istering or alining the delivered sheet preparatory to being operated on by the machine; and to that end the invention consists, essentially, in the combination, with said machine, of a. registering instrument adapted to engage a sheet after its initial movement is arrested by the end gage and draw or move it backwardinto registered position. Toaccomplish this result, the end gage is located to allow the sheet to be fed into the machine a little past the desired registered position when the registering instrument engages the sheet and draws it back.

In order, that my invention may be fully understood, I will first describe the same with reference to the accompanying drawings and afterward point out the novelty with more particularity in the annexedclaims.

Referring to the annexed drawings, Figure 1 is a plan viewof a paper-folding machine provided with myimproved paper-registering devices. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged side viewof the registering instrument with a portion of the subjacent paper-s11 pporting bar broken away .the accompanying draw- I to better illustrate-the foot of said instrument, and Fig.4 is line X X in Fig. 3.

Similar letters of reference indicate corresponding parts.

A denotes the main supporting-frame of the paper-foldin g machine.

' B B representthe paper foldiug rollers; ,C, the blade which tucks the paper between the foldingtapes which extend from the feeding or paa transverse section on per-receiving end of the machine to the folding-rollersand convey -the sheets ofpaper into the machine, and D represents the first foldguide or end gage which arrests the movement of th p p rdeliveredby the aforesaid-tapes. All of said parts'are arranged and operate in the usual and well known manner.

Though I do not limit myself to any specific construction, arrangement, or location of the paper-registering instruments, yet I prefer to construct them to engage the rear edge of a previously-formed slit in the sheet rollers; a a, the travelingendless and locate them between the folding-rollers and paper-receiving end of the machine, so

as to facilitate the drawing back of the de- I I livered sheet to its requisite registered position. I employ two of said registering instruments, disposed, respectively, at opposite sides of the machine, as shown in Fig.'-1 of the drawings. For supporting these instruments so as to adapt them to operate on sheets of paper of different lengths and widths I sr cure the longitudinal central line of cross-bars b b to suitable standards I) and b mounted on the frame A at opposite sides of the machine. Said cross-bars are located one near the folding-rollers B B and the other at or near-the paper-receiving end of the machine. To said cross-bars are attached the ends of longitudinal bars 0 c, which are parallel with-the tapes a a and are adapted to be shifted laterally and clamped adj ustably on the 'cross-bars to carry the registcringinstruments in lines directly over the slits made in the paper for the purpose of registering said paper. Upon each of the said longitudinal bars'is mounted a sleeve c',which embraces the bar and is slitted longitudinally to render it contraotible and'is provided with longitudinal flanges at the edges of the slit, through which flanges pass bolts, bymeans ofwhich the purpose hereinafter explained.

an axle d, which is journaled in bearings on" the sleeve. Said fingerextends downward from the axle and has its foot or lower end provided with a spur e, which projects rearward or toward the paper-receiving end of the machine, and with aforwardly andnpwardly curved shoe e, which latter guards against the catching of the paper and tearing it during the forward movement of the fillger.

This finger or registering instrument receives oscillatory and longitudinal reciprocating motion by means of a crank f, at.-

tached to the axle of the finger and connected to the end of a 'rod g, which is parallel with the longitudinal bar c-and'is connected to one of the arms h,.fastened to arock-shaft h ,u which is actuated by an arm '5, fastened to the j end of said shaft and connected to the end of'a pitman j, which depends from said arm and is bifurcated at its lower end and straddles thereby a rotary shaft Z, to which is secured a cam 1'. To the pitman is pivoted a roller n, which rides upon the said cam and causes the pitmanto be intermittently lifted by the cam. A spring a and the weight of the pitman depress the latter, and thus the pitman receives reciprocating motion.

A In connection with the finger or registering instrument d I prefer to employ a' longitudinal papersupporting bar R, which is arranged between the tapes an and parallel therewith and is.provided with a longitudinal groove R in its top, as more clearly shown in Figf i of the drawings.

cross-bars 0 o, secured to the frame A at opof the paper..

which is illustrated in Fig. 3 of the drawings,

and consists of forming said rod of two end sections having their adjacent ends inserted into a sleeve 9' and adj ustablyfastened thereinby set-screws g k The operation of the described registering devices is as follows: The paper is conveyed into the machine by'means of the tapes a a, and its motion is. arrested by the usual end 'gagerD, which leaves the paper lying with its central portion across the folding-rollers B 3. During this operation the registering instrupaper;

In order to allow the said registeringinstruments to be adjusted for operating on' difierent papers having the registering-slits in diflerent positions, I mount the bars R R laterally adjustable'on paper-operating device.

"ments d are carried to their extreme forward position and are lifted out of the path -of -the:paper by the rods 9 g being pushed forward by the arms h h. of the rock-shaft h.

As'soon as the sheethas'comes'torest the rods g g begin to move back and thereby first tilt the fingers or registering instruments It cl, so as to cause their lower ends to depress the paper in the grooves R'IOf the bars R and.

then ldraw said instruments back, and in this movement? the Spurs 6 of the instruments d i enter into the slits ofthe pap er,"whichslits are opened .by the aforesaid-depression of the In the'furtjher. rearward movements of said instruments they come in contactwith the rear edges of the slitted portions of the paper and draw the paper rear-ward to its requisite registering? position. As soon as it their forward movement and thereby lift the registering instruments d out of engagement 'with the paper and release the; same, to' be then tucked into the bite of the folding-roll- In orderto prevent the tapes from disturbing the paper from its aforesaid registering'position, the movement of the blade 0 is to be so timed as to cause it to come in contact with the paper the moment the paperis released from the registering instruments. c

To guard against excessive downward pressure ofthe finger .or instrument dupon the paper, -the pivoted,endjof said finger is pro vided with a rearward extension t, to which is adj ustably connected a vertical set-screw t, whichby contact'with the sleeve 0" limits the downward movements of the finger d.

The essential feature of novelty of my improved sheet-registe'ring machine'comprises, in combination with the paper-folding machine or analogous machine,sn'itable sheetregistering instruments adapted to engage the sheet after it has been fed into the folding-machine or-other machine and draw it has arrived at vthis position the rods g'begin back into registered position in readiness for the operation of the folding-knife or other ture and location of theregistered instruments described and illustrated may be altered to suit varying requirements, as they The specific struc-- machine provided with traveling tapes conveying paper into the machine, paper-registering instruments located and reciprocating in lines parallel with said tapes and movable toand fromthe planethereof and drawing the paper back to its-registering position, as
