JOHN A. WHERBY, OF NEW ORLEANS, LOUISIANA, ASSIGNOR TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, ,N. Y., A CORPORATION OF DELAWARE.

TYPEWRITING-MACHINE.

To all whom it may concern:

Be it known that 1, JOH A. WHERRY, a citizen of the United States, residing in New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.

This invention relates to a collating device for assisting in assembling, without the use of impaling studs, a plurality of work-sheets of different character in various predetermined relations to one another, so as to place them on the typewriter platen with certain lines on the several sheets in register with one another.

In my application No. 184,820, filed August 7, 1917, (now Patent No. 1,300,905,

, dated April 15, 1919) aflexible collating sheet or back extends around the platen and is provided with a seriesof impaling studs on each side, for maintaining a plurality of different perforated work-sheets 1n predetermined relative positions. The flexible collating member positions the work-sheets in a pack'ion the platen. It is moved back and forth by spring-actuated lazy tongs, which maintain the flexible collating member taut on the platen.

In the present case, instead of using collating studs which require preparatory perforation of the work-sheets, clips are used, which do not necessitatepreviously perforated sheets, and preferably do not perforate the sheets at the time of typewriting. The clips are located on a flexible collating back or member and pass around the platen with thsame, and maintain the assembled pack. of sheets in a smooth condition andpreserve their register.

The clips are maintained in their normal positions by spring means which yield slightly to allow for the bending of the work-sheets as they pass around the platen. A certain amount of tension on the sheet is maintained. The clips are arranged in pairs tending to pull a sheet which they hold in opposite directions, so as to keep it smooth.

A suitable scale may be provided on the flexible collating member to position the work-sheets relatively thereto and relatively to each other. This scale bears a definite relation to a pin eifective to stop the backward rotation of the collating table Specification of Letters Patent. Patented Aug. 31, 1920. Application filed December 1. 1917. Serial No. 204,968.

when the first line of writing is at the printmg point. This pin may be adjusted on the collating member, so as to vary the amount of backward feed by securing it in any one.

line 3-3 of Fig. 5, showing one of the clips in its active gripping position.

Fig. 4 is a view similar to Fig. 3, except that the clip is opened to either release a. work-sheet or take in a work-sheet to be assembled.

Fig. 5 is a front view in elevation, partly broken away to show the underlying structure; the collating member being partly moved down in front of the platen.

Fig. 6 is arear view of a portion of the flexible collating member, showing one of the clips and the spring for actuating the latter. v

A platen 1 is mounted to rotate on a typewriter carriage 2. The platen and typewriter carriage are of the usual Underwood standard make. The platen 1 is rotated in the usual manner either by hand knobs. 3 or by line-space-mechanism, indicated in generalat4..

For the purpose of holding the worksheets on theplaten, there are provided the usual pressure feed-rolls 5, which are mounted on rods 6 supportedby bell cranks 7. The bell cranks 7 are arranged in pairs and are provided with arms 8, which enga e may be operated from the. usual pressure feed-roll release indicated at 11, which is I connected to the rock shaft by a link 12 and an arm 13. The rock shaft 10 may also be operated from a special release finger-piece indicated at 14, which is connected to the rock shaft 10 by means of a link 15, and a line-space detent throwolf 16 connected to throw off the feed-roll 5 by means of a link 17 connected to an arm 17, extending from the rock shaft 10. When the platen is thus released, a spring 18 (Fig. 5) becomes effective to withdraw a flexible collating member 19, preferably made of sheet-metal, so as to introduce work-sheets to bring the first line to'the printing point. This mechanism is more fully described in my abovementioned application.

. For the purpose of assembling a plurality of work-sheets of different character, so that differently positioned lines on the work- 20 I other movements, a connection in the form sheets may be brought into register with one another, there is provided the collating back 19 which is in the form of a flexible member extending around the platen 1. To cause the collating member 19 to move evenly with the platen, during its line-space or .release of the platen from its detent. Both the lazy tongs and the ends of the collating member may be'guided by pin-and-slot connections to plates 24 and 25 provided on the ty ewriter carriage 2. v

hen the work-sheets are to be assembled or collated, the member 19 is adjusted to the position shown in; Fig. 1, with the front end thereof extending .considerably above the printing pointof the platen 1, so as to bring a scale 19? and clips 26, which are used to position and. hold the worksheets, respectively, on the collating -member 19, into view of the operator. To attach the work-sheets I employthe clips 26. There may be a series of these clips at one side of the collating member 19, preferably at each side, all of them forming a plurality of sets which make it practicable to grip the work-sheets individually from opposite sides, or on only one side The clips are preferably arranged in pairs, the members of each pair being one above the other and acting in opposite directions, to maintain.

, the particular work-sheet which they engage in a smooth condition upon the collating member 19, and also so as'to maintain the work-sheets in proper position as they pass around the platen 1.

' Each 'clip 26-may include a frame 27, shown in the form of a plate havin an pening 28, Fig. 2. The plate27 is p otally attached to the collating member 19 by means of a stud 29 which extends through an opening in the plate 27 and a hole in the member 19. The plate 27 forms one of the jaws o'f'the clip, but is located on the under side of the collating member 19. The other jaw of the clip, indicated at 30, is pivotally connected to the plate 27 and is on the upper side of the collating member 19, so as to rock toward and from the collating member 19 and plate 27. This pivotal connection is in the form of a hinge having one section 31 on the jaw 30, and two sections 32 on the plate 27 The sections 31 and 32 of the hinge are connected by a pin 33, which permits the rocking of the jaw 30 tois provided with a button 34, which extends through an opening 35 provided in the collating member 19, so as to directly engage the work-sheet or sheets, and assist in making the clip 26 positive. This button 34 preferably does not pass through the-worksheet and is not, therefore, in the nature of an impaling stud.

The extent'which the work-sheet can enter the clip 26 is limited by a gaging stud 36, which is secured to the plate 27, and extends through an opening 37 in the collating member 19 and through an opening. 38 provided in theupper clipjaw 30. The connection of the stud 36, with respect to the plate 27 and the upper jaw 30, is such as to allow a cer-' tain amount of relative movement, so as to enable the jaws to grip and release the worksheets.

Normally, the j aw 30 is held with its gripping end against the button 34 of theplate 27 by means of a spring 39, which may be located at the opening 28 provided in the frame or plate 27 The clip jaw 30 extends at its non-gripping end into the opening and is engaged by the spring 39. To release the clip and move the aw- 30 at its gripping end away from the plate'27, there is provided a release device 41, shown in the form of a finger-piece or arm secured to the pivot 29. This finger-piece is provided with an engaging portion 42, which engages a cam 43 provided on the non-gripping end of the jaw "30 to press the latter end and raise the gripping end thereof. This causes the clip or clamp as a whole to spread (Fig. 4), and thus release the work-sheet held' thereby or permit a work-sheet to be inserted therein.

The release 41 also acts to move the clip 26 as a unit about its pivot stud 29. This movement of the clip about the pivot stud 29 is permitted by-making the openings 35 and 37 in the form of elongated slots. The movement of the finger-piece 41, about the pivot-stud 29, is opposed by a spring 44 which is connected at one end'to the collating member 19 (Fig. 6), and at the other end to anarm 45 secured to the pivot stud ward and from the plate 27. The plate 27 I mined by the limit of movement of the parts 34 and 36 in the slots 35 and 37. When the ,release is actuated, it rotates the pivot 29 and the-arm 45 to swing away from the spring 39 and against the tension ofthe spring 44, thus relieving the clip 26 of the tension of the spring 44. The portion 42 of the finger-piece 41 engages with the cam 43 on the non-clamping end of the jaw 30, but the tension of the spring 39 may be great enough to prevent the actuation of the cam and the swinging of the jaw about its pivot at this time. Thus the clip, as a whole, will swing about its pivot 29 until the members 34 and 36 strike the opposite ends of their respective slots, thus preventing a further movement of the plate 27; but the fingerpiece 41 has an additional movement about its pivotto raise the clamping end of the jaw 30 by swinging the latter about its pivot 33 after the clip as a whole is arrested by the members 34 and 36 striking the ends of their respective slots. The cam 43 is then actuated by the sion of the spring 39 to open the clip for the insertion of the paper. The finger-piece 41 is arrested in its extreme actuated position by a stop 46 secured to the plate 27.v A work-sheet is now inserted between the clamping end of the jaw 30 and the button 34 on the plate 27, and the finger-piece is permitted to return to its normal position under the tension of the spring 44. The first part of the return movement of the finger-piece is independent of the plate 27, to clamp the work-sheet by setting the cam 43 free to be swung to its normal position by the spring 39. After the finger-piece 41 has moved clear of the cam 43, the arm 45 on the pivot stud 29 strikes against the spring 39, thus tending to swing the clip, as a whole, about its pivot 29 to its original or normal position. 0 insure the clamping of the work-sheet before the clip as a whole is permitted to returnto its normal position, there may be provided an extension or hook 43" on the cam 43, which, when the clamp is in its effective or releasing position, engages in a hole 43 in the collating member 19.

It will be remembered that the work-sheets may be held by sets of clips, there beingtwo in each set, which are so arranged that their springs 44 will tend to swing their clamping ends away from each other, thus keeping the work-sheets taut, Fig. 5. The release 41 for the two clips of a pair move from opposite sides ofthe'ir respective clips toward each other when brought into action. The springs 44'a'lso act in opposite directions, so that the active ends of the clips of a pair are yieldingly held by the springs 44 in the pofinger-piece 41 against the ten-- work-sheet gripped by the pair of clips.

sitions farthest away from each other. This is for thepurpose of maintaining the worksheet or sheets in smooth condition on the collating member, and to prevent any slackness of the work-sheets. The platen is grooved or cut away atone or both ends at 49, to give clearance for the rows of clips.

The collating member 19, at the start, may be advanced to Fig. 1 position, with the front end thereof and the scale 19 extended considerably above the line of writing at the printing point of the pl aten. The

work-sheets, which may also have indices thereon, are then placed on the collating member 19, one by one, with the interleaved carbon sheets, with the aid of the indices and the scale 19*. Each work-sheet may be gripped individually to the collating member 19, to allow for different relative placements of the work-sheets. Preferably a sheet is gripped by a pair of oppositely acting clips 26. Normally, the clips are in gripping condition. They are opened by the operation of the release 41. The action of this release is first to swing the clip as a whole against the tension of the spring 44 about the pivot stud 29. A c'ontinued movement of 'the'release 41 cams down the tail end'of the jaw 30, so as to raise the active end thereof. For the case of the uppermost clip 26 in Fig. 1, the movement of the active end of the clip will be downward, and for the clip next below the movement of the active end will be upward, so that the movement of these two clips, which form a vertically-spaced pair, will be toward each other at their active ends. The clips are held in this position until the work-sheet is inserted between the jaws of the clips; the sheet being positioned by its side edge engaging with the limiting studs 36. Then the pressure of the two releases 41 is removed, so as to permit first the spring 39 and then the spring'44 to act The springs 39 cause the jaws 30 to come down in tight engagement with the work-sheet, and at the same -time the springs 44 tend to cause the active ends of the clips 26 to spread relatively to each other, so as to smooth out till? desired, the work-sheet may be gripped on both side edges with the assistance of another pair of jaws provided at the right sheets and hold them taut on the collating member 19.

The collating member 19 may then be drawn backwardly and areverse rotation of the platen 1 effected to bring in superposed initial lines on the several sheets, which were brought into register with each other, into conjunction with the printing point of the pla n- To permit this a tion,

the release 14 is actuated to throw off the feed rolls 5 and release the platen from its detent mechanism in a manner more fully described in my above-mentioned application.

The reverse rotation ofthe platen and the collating member 19 may be accomplished automatically, and the amount of reverse rotation determined automatically by means of the release 14 and the stop pin 19", which engages a bell crank 48, in a manner more fully described in my abovementioned application. in addition to limiting the backward rotation of the platen 1 and the collating member 19, operates the release finger-piece 14, which may bring into play the pressure feed-rolls 5 which had been previously withdrawn to their active positions, so that they preferably assist in holding the worksheets against the platen after a reverse insertion thereof. The typewriting may then go on, and the line-spacing mechanism be actuated to feed the work-sheet forward from line to line. As the flexible collating member is fed upwardly in front of the plate 25, the clips holding the work-sheet swing away from each other slightly to take up the slack caused by the bending of the work-sheet with the collating member around the platen.

It will be seen that when the work-sheets are held at one side edge thereof, the feed rollers 5 are effective to assist in guiding the loose endof the work-sheet around the platen. If, however, each side edge of the work-sheet is held by a set of clips, the feed rollers are not necessary to guide the worksheet around the platen as it is held in a taut condition on the collating member, and may be fed to and from the printing point by the platen 1, which forms a driver for the collating member by engaging the latter by the teeth 20, as hereinbefore described.
