SHEET-REGISTERING DEVICE.

Specification 'of Letters Patent.

Patented Apr.13, 1915.

Application filed September 18, 1913. Serial No. 790,527.

To all whom it may concern:

Be it known that I, EDWARD CHESHIRE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Sheet-Registering Devices, of Which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention pertains to sheet registering devices, and relates especially to automatic registering devices for use in connection with printing presses of What is known as the Gordon type.

In my Letters Patent No. 964,7 56 granted July 19, 1910, I have described and claimed a sheet registering device of the same type as that which forms the subject of the present invention; and it is one" of the objects of the present invention to improve upon the device disclosed in the aforesaid Letters Patent.

It is another object of the invention toprovide a registering device which, when used in connection with an automatic mechanism for feeding sheets to the press, will.

prevent the sheets from rebounding froin the registering stops on the platen.

It is a still further object of theinvention to provide a sheet registering device which will be simple in construction and eflicient and certain in operation, which will be readily capable of adjustment forvarious sizes of paper and positions of the paper upon the platen, and which will not vmar the surface of the paper in connection with which it is used.

that which is described and shown and that changes may be made in the details of construction of the embodiment shown, without departing from the scope of the invention,

' as defined in the appended claim.

In the drawings; Figural is a plan of the platen of a Gordon press having a sheet registering device constructed in accordance with my. invcnjion applied thereto. In this nature to Fig. 2

A sheet registering device constructed in.

figure the gripper fingers are shown raised to permit paper to be fed and the register arms are ust receiving a sheet of paper. Fig. 2 is a fragmentary view of a similar nature to Fig. 1, showing the register arm which movesthe sheet against the end and lines in this figure. Fig. 3 is a side. elevation of the parts shown in Fig. 2, in the corre spending full-line and ,dotted positions.

Fig. 4: is a detail section taken on the line 44 of Fig. Fig. 5 is a view of a similar but showing the register arm which pulls the sheets downward only. Fig. (3 is a which supports the register arm and associperspective view of the bracket,

ated parts shown in Fig. 5; Fig. 7 is a per spective view of the holder for the register arm shown in Fig.

Like reference characters refer to like parts throughout the following specifica-v tions and the several figures o'f'the accompanying drawings.

The device is illustrated as applied to the platen ofa press of the Gordon type, the platen being indicated as l0 on the drawings. The platen is provided with the usual tympan-retaining bails 'l 1, and end stops 12 against which the sheets of paperare adapt ed tobe successively placed. A side stop 13' is also provided against which the'side of the sheet engages when the sheet is in proper register.- livoted to the platen is a gripper bar 14 whirlr carries gripper lingers 15, the function oi which is to retain the sheet in place during the printing operation and prevent the printed sheet from adhering to the type when the platen recedes from the bed. The above are among the ordinary equipments of a (lordon press.

The sheet registering device now to be described includes a registering arm which pulls the sheet-first against the end stops 12 and then against the side stop 13, in the manner similar to that disclosed in my letters patent above referred to. In addition, a second registering arm is provided which I pulls thelslieet against-the end stops-only,

" I be loosened at will, to permit longitudinal adjustment of the registering arm for varipassing ofl the sheet before the first-named registering arm pulls the'latter against the side stop. I will now describe the register ing arm first named above. I

Referring particularly to Figs. 1-4, 16 indicates a bracket which is' secured to the edge of the platen by means of clamping plates 17 and 18'which engage over the edges of one of the bails 11. Projecting upwardly through and enters a fork formed in a holder 24 for the'registering arm 25/ The pin 23 is secured in the fork by means of a vertical pin 26; and it will be seen, therefore, that a universal connection is made; between the holder-24 and-the hanger 21. The registerin arm 25'projects over the platen from the ho der 24, andis held in place in the latterby-means of a clamping piece 27 which may ous sizes of sheets and various positions of the sheets upon the platen. At its front end, :the, registermg arm is formed with a fork having three tines, the centerof which, 28, lies closely upon the 'tympan, and the outer of which, 29, are bent upwardly. A guardplateBO is secured to the bracket 16 so as to engage the upper. face of the registering arm 25, therebyholding against the tympan at all times.

The holder 24 is provided with a laterally extendin arm 31 which enters an elongated slot 32 orm'ed. in an upwardly extending flange 33, with which the clamping plate 18 is provided. When a sheet is fed to the platen its front edge, near one corner, enters above the tine 28 and below the tines 29, the sheet being thus cr'imped sufficiently to hold it impositively in connection with the regarm. The-sheet will then be sub-.

isterin stantia ly in position shown inF g. 1. After the sheet has thusbeen fed to the platen, and the latter begins to move to its printing position, the gripper bar 14 swings upwardly about its pivot, thus causing the hanger 21:

to bemoved to the left (-Fig. 3), whereby the registering arm is pulled toward the edge of with it the sheet against the platen, carryin the endstops 12." ust after the registering arm has efiected this,

the positionshown in full lines inFigs.

2 and 3, the end ofthe arm 31 engages-the left hand end of the. slot 32: so that, during;

The'hookferring now sheet against the arm 41 moves lengthwise out of engagement described above,

the parts being then, Letters Patent, is:

the further movement of the gripper barj14, the holder 24 is caused to swin' about the pivot pin 26, the registeringarm hus swinging toward the side stop 13 and carrying the sheet against the latter. By the time the gripper bar 14 has completed its movement, the registering arm will have swung clearof the paper, as indicated in dotted lines'in Fig. 2, leaving the sheet in engagement with the end stops 12 and side stop 13, and consequently in proper register.

n I I I The second registering arm operates in a above, but it has, no sidewise movement. Re-

A guard plate 43 is secured to the bracket 34' over the registering arm 41, thereby retaining it close against the platen The registering arm 41 operates similarly to m 41, the latter being adju t. ably secured in the holder by means of a re-j.

In the use of automatic feeding mechanits use insures that after having brought the ism in which the sheets are fed against stops.

upona platen, sheet will rebound from the stops, thereby becoming placed out of a proper registering position; and this is particularly so in the case of mcchanisms which run athigh speed. By the use of the sheet registering device I 7 this disadvantage isjentirelyobviated, since the sheet is fed into the jaws of the" register ng arm and retained proper iregistering position. the device especially useful in connection with automatic sheet feeding mechanisms. 7 Having thus fully described my invention, what I claim as new and desire to secure by The combination with a end stop and aside stopthereon, of a pair of sheet-receiving registering arms, means it frequently occurs that the ,115,
