TYPE-WRITING MAC INE.

i Application filed May 27,1914. Serial No. 841,184.

To all about it mag concern)- Be it known that I, Jussn A. B. SMITH, a cltizen of the United States, residing in Brooklyn borough, inthe county of Kings,

city andState of New York, have invented certain. new and useful Improvements in Type-Writing Machines, of which the following is a specification.

- This invention relates to sheetcollating devices for typewriting machines, and is directed toward the general constructlon and arrangement of such devices as shown in Patent No. 1,107,372, granted August 18,,

One of the objects of the present invention is to provide an improved form of collating board or f 'ame having sheet-carrying devices and upon which the sheets to receive writing may be assembled while said board lies in a forward position, to which it is capable of adjustment. In such position,

'the collating board ext-ends about horizontally toward the operator, thereby permitting the operator to readily and conveniently adjust the sheets. This advantage is gained by means of the provision of an angle in the collating board, which allows the lower portion thereof (which may be mounted on the platen axle) to extend at an upward and forward inclination for a sufiicient distance, so that when swung forwardly the board will clear the top front bar of the machine,

'- thereby permitting the upper portion of said boardto lie in the desired horizontal plane. A'further purpose served by the provision of the angle, is that the consequent forward inclination of the lower portion of said collating board (when upstanding) presents the sheets in a more direct introductory manner to the platen.

, The sheet-carrying devices which consist, of endless bands having studs to enter apertures therefor in the sheet margins, also have apertures by which they may engage with teeth arranged Upon cylindrical caps disposed one at each end of the platen, and also with teeth upon pulleys mountedin bearings at each end of the upper port on of the collating board, to divide the carrying strain for each hand between the platen and said pulleys, and to dispense with lateral guides for preventing the bands from slipping off the pulleys.

The toothed, cylindrical caps may fit over recessed portions at the platen ends 1n order 7 ceive the pulley shaft, these strips being supported on rods which are mounted upon springs in brackets provided at the opposite upper corners of said collating-board, the springs providing a flexible support for the pulleys to take up the slack in said endless bands. The bent. ends or walls of the said strips have rounded upper. edges to receive the ends of an outer curved guide plate, which is adapted to fit. over and cover the i entire upper length of the collating-board, including the pulleys and which also covers an inner curved guide plate that extends between the pulleys, there being a clearance between said outer and innerguide plates for the passage of the work-sheets. The outer guide plate has transverse enlargements at its opposite ends to provide clearance spaces for the passage'therethrough of the projecting studs upon the endless bands, and means of connection between said outer guide plate and said pulley-supporting members or strips are provided whereby said outer guide plate may be secured in position.

The forward lip of theouter guide plate flares forwardly to facilitate entry of worksheets and the adjacent edge of the inner guide plate flares rearwardly for a similar purpose. A finger extends downwardly and rearwardly from said inner guide plate to" prevent the centerof the work-sheet being carried upwardly from sagging and for directing the leading ,edgeof said work-sheet between the lips of} the outeryand inner guides. The side edges of the collatingboard are provided with guidestrip's' for the endless bands, said guide strips extending over the outer edges respectively of said bands, Sand said guide strips may be provided each with a scale Whose graduations bear numbers whereby -may be designated the position of a desired writing line in assembling the Work-sheets.

Means for supporting the: collating-board when brought to the horizontal position for assembling sheets thereon consist of brackets having curved upper surfaces mounted upon the front bar of. the platen frame, which forms part of theilsual carriage, to

be movable therewith, said brackets being in position respectively to engage the endless bands, which-latter, under the weight of the collating-board which they carry, yield to the curvature of said bracket supporting surfaces, said brackets having grooves or recesses to receive the paper engaging studs on the bands in order that even contact may occur between the bands and brackets during the support of said bands by said brackets.

The rear plate or frame which supports the adjustable collating-board when in its operative position is securely supported in an upright position upon the forward sur face of the paper table, and is provided with an inclined lower portion whose angle coincides with that of the collating-board whereby the opposed surfaces of said collatingboard and the rear plate lie in parallel planes spaced apart sufficiently for the travel of the endless bands and the work-sheets they carry. The rear plate or frame has lateral lugs with bearing surfaces a little in advance of the front surface of said plate adapted toengage bearing surfaces on the collating-boari'l whereby said collating-board is supported in the desired relative position upon said rear plate or frame.

' In order that [no .-='i lating-board when drawn forwardly to horizontal position may be held in that position agains' the tensionof the springs which are retracted by the endless bands yielding under the weight of said collating-board, I provide catches which may be mounted upon the platen frame at each side thereof and have cam surfaces'associated therewith, the collating-board having crank arms extending from a spring held rocking-rod, journaled in lugs extending from said collating board, whereby as the collating-board is swung forwardly the crank arms ride over the cams and engage with the catches to hold the collating-board horizontally until released.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspectiveelevation of my improved collating-board shown as mounted upon'the carriage of an Underwood typewriting machine and in operative position. Fig. 2 is a similar view, the collating-board being shown as swung forwardly to a horizontal position for assembling sheets their n, the rear supporting plate being partly broken away and the outer guide for the collatingboard shown as removed. Fig. 3 is a side elevation of the collating-board shown in operative position. detail side sectional view showing the upper pulley, the endless band thereon and the inner and outer guides. Fig. 5 is a partial view in side elevation showing the collatingboard swung forward to horizontal position,

Fig. l is an enlarged.

space mechanism which may coin-prise a ratchet wheel a fixed to the platen axle and rotated by a pawl 6 pivoted at 7 to the slide 8, the latter actuated by a line-space lever 9, which also. serves to return the car riage. I

The throw of the pawl may be regulated as usual by a gage 10 adjust-able by a hand lever 11 to vary the point at which the pawl 6 is permitted to move downwardly into engagement with the ratchet wheel, and thus determine the effective throw of the pawl. The usual. spring-pressed detent 19 engages the ratchet wheel to hold the platen at line-space intervals and prevents accidental movement.

The collating board 13 is here shown as having forwardly-extending brackets or lugs forming bearings ll by which it is pivotally mounted upon the platen axle 2. Said collating board might be otherwise mounted,

but it is manifestly convenient to provide a common axis for both the platen and collating board in view of the fact that said collating board is intended to swing over th platen from an upright operative position, shown in Fig. 1, to a horizontal position. shown in Fig. 2, in which latter position it is adapted to receive the different worksheets for which it is intended.

The collating board may be of suitable construction and' material, and as here shown it consists of a light frame in the form of an aluminum casting having intersecting bars with open panels, thus possessing the desired degree of "igidity and strength. and of light weight. The collating board or frame at its junction with the lugs 01' brackets ll is offset with relation to its axis, and from that junction it extends to a point 15 at an angle which, in the operative position, gives it a rearward inclination relatively to the main forward portion of said board, which rises nearly vertically therefrom, or with only a slight rearward inclination. The rearward inclination of the lower portion of the collating board allows its upper portion, when swung forwardly over the platen and front portion of the machine frame, to be presented in such manner as to lie horizontally before the operator.

Mounted in brackets 16 upon springs 17 arranged near, each upper end of the collating-board are rods 18 which thus yieldingly in operative position. The collating board support a bearing strip or frame-comprismg a base 19 to which said rods are secured,

and upwardly extended end walls 20, having alined orifices 21 forming bearings for pivots22 which carry the pulleys 23. Said pulleys are providedwith peripheral teeth 24 which cooperate with teeth 25 upon the cylindrical caps 26 fitted on the platen ends to carry endless belts 27 which have orifices 28 arranged in a line to feed over said pulleys and platen ends by means of said peripheral teeth. a

The cylindrical caps for the platen ends may have hubs 29 whereby said caps serve the purpose of the usual platen end plates, the cylindrical or pulley portion of said caps having a diameter equal to that of the platen, which latter is annularly recessed to receive said caps and allow their cylindrical surfaces to lie flush'with thecylindrical surface of the platen. bands 27 each carry in an endless line a row of studs 30 spaced apart in accordance with the spacing between the apertures in the work-sheets to be carried by said bands, the

studs 30 engaging said work-sheet apertures to advance said work-sheets with the travel of said bands, and said. bands ad'- vancing with the step-by-step line-spacing rotation of the platen, or with the platen as otherwise rotated.

The collating board is supported, when in its upright operative position, by means of a rear plate or frame 31, which may be of similar character to the collating board in.

its structure, and is illustrated as of such construction, being composed of intersect-T ing bars with open spaces or panels for the sake of strength and rigidity, with light weight. Frame 31 is provided with a smooth front surface plate or sheet 32,-w-hi'ch is secured thereto as by screws 33, w herefore said frame with its sheet 32, conforms in contour with the collating board 13, s'o'that the latter may lie parallel therewith,when

l3 has side lugs 3l with bearing surfaces adapted to engage laterally extending lugs or brackets 35 on the frame.3 1,said lateral lugs lying in the path of the lugs3lon the collating frame in order to arrest the rearward movement of said collating frame a little in advance of the surface plate 32, and

n tion of the main upper portions of said collating board and rear frame, the co1lat-- ing board when moved rearwardly to its operative posltion, isretamed 1n that operative position-by gravity.

The endless The front bar 36 of the platen'franiehas mounted thereon, near each end, a bracket consisting of a'member 37 having a curved upper surface with a, groove or depression 38 extending transversely thereof, ,-.said* curved memberliaving legs 39 withfeet {:0 by which they aresecured, as w th screws,

to said bar. The said. brackets nepotitioned uponthe frame in alinement with the endless bands 27 to engage the, latter when the collating board is swung down horizontally over the front part of the ma.-.

chine, the grooves or depressions 3Sfthenrer 'celving the studs 3.0 upon the endless belts,

and said belts yielding through the e pr ssion of the sprmgs 17 under the welght of the collating board, whrch they support, to

conform to the contour of said brackets, and

thereby allowing the-collating board to be .lowered to present its surface horizontally,

toward the operator. The work-sheet, such as ledger sheets, invoice sheet, statement,v

and other desired work-sheets, can be arranged in superposed relation, with inter-. leaved carbon sheets where desired,upon the.

collating board thus extended"horizontally toward the operator, the work-sheets being assembled upon said collating board by placing their marginal orifices over the;

studs 30 on the The collating boar is provided ffon its assembling surface, at one or both sidesv .thereof, wlth aguide str1p 41 which hes over the outer'edge portion of an adjacent endless band, and said guides may each have mounted upon them, a scale plate l2 bearing numbered graduations at line space'1nter-- va'ls apart, whereby the operator upon insertlng a' new work-sheet may conveniently register the-writing lln'es thereon, in accordance with linespreviously -writ ten upon other work-sheets, borne. by the collating board; The end walls 20 of the pulley bearing frame, 'whichare of rounded contour at their upper portions, are thereby adapted to support an outer guide plate l3. which is .of inverted. trough-like configuration, "with open ends to receive said walls 20, and said walls may have :mturned' flanges'll,;fro nt and rear, to provide engaging surfacesby which said-trough maybe conveniently detachably secured in position, as by the use of screws. The guide plate l3, which thus ex' -e "tends over the entire upperportion ofzthe' collating board, includingtheendless bandsg is spaced. apart from said endless bands to provide suthcient clearance'for-the passage of the work-sheets carried by said endless bands, which are thus passed upwardly around the inner surface of said guide'plate to descend at the rear surfaceof the collat-.

inc: boardbetween-it and the surface plate 320i the rear frame 31.

The outer guitle plate l3 aforesaidhas transversely expanded enlargements '44 lyingover that portion of each endless band carrying the studs 30, to provide clearance spaces for the passage of the studs, these enlargements it being desirable because by or lip -l of the guide flared to facilitate en- An inner guide plate -tG is also provided, this guide plate l6 extending over the longitudinal space between the pulleys 23 and downwardly beyond the latter .on opposite sides, and having an upper surface curved in substantial conformity with the cylindrical contour of the upper portions of the pulleys. The forward extension of this guide plate l6 has an inwardly flared edge or lip 4:7 to cooperate with the outwardly l3 for the introduction to the space which is provided between the guides, of worksheets which are to. pass through said space in traveling around to the rear of the col lating board. I

The rear portion of the inner guide l6 extends over the upper portion of the rear surface of the collating board to form a portion of the supporting surface thereof. Said inner guide may be secured in its position as noted, by means of inturned lugs 48 which extend from its forward and rear portions at the sides thereof and are adapted for engagement with the inner faces of the walls 20 of the bearing frame.

It will thus be apparent that sheets assembled upon the endless bands, when ad vanced around the platen and up to the top of the apparatus, will by means of the outer and inner guides, be directed. around the top portion of the collating board and downwardly between said collating board and the rear frame, at which point, without removal of said assembled sheets, or with removal of some of them, other sheets may be assembled on top of said sheets fora second passage around the platen.

To prevent the sheets ascending in front of the machine from sagging at the center, between the two endless bands and thereby failing to freely enter the space between the guides a guide finger 19 is attached to the lip or edge Jr? of the inner guide, said finger extending downwardly and inwardly to the surface of the collating board, to which it may be made fast, as seen, thereby serving to properly direct the leading edges of worksheets which may sag centrally, to the entrance at lips 45, 47, between the guide plates. 7

It will be seen that the weight of the collating board and the rearward inclination it assumes in its operative posltlon serve flarededge 45 of guide which has thus occurred allowing said 001- la ting board to present its rear surface more nearly in a horizontal position than would be possible were the endless bands unyielding and incapable of sagging in the manner described. I

In order that the collating board, as thus presented to the operator, may be sustained in that position while sheets are being assembled thereon, certain locking means are provided as follows. The lugs Ell upon the collating board serve as-bearings for a rod 50, which is adapted to rock therein but is restrained by a spring 51. Said rod at its outer ends is provided with crank arms 52, adapted in the forward swinging movement of the collating board to meet and ride over cam surfaces 53 provided on brackets 54, which also have forward projections forming catches under which said crank arms 52 become engaged by the action of spring 51, this latching or locking action occurring at the time when the collating board has been brought fully forward and the endless bands sagged to sufficient extent to present the collating board as stated in a substantially horizontal position. In order to return the collating board to its operative position, the crank arms are released by hand from the projections Variations may beresorted to within the scope of the invention, and portions of'the improvements may be used without others.
