STENCIL-CABD-FEEDING ATTACHMENT TYPE-WRITERS.

T aZZ whom it may 00mm;

Be it known that we, ALFRED L. McCAW-,

be simple and reliahle in operation and which may be readily attached to a typewriter to permit of'thc use ofthe latter for the purpose indicated. The preferred. embodiment of the. invention shown. in the drawings is intended for application to the Well-known Underwood typewriting inachinc, and is illustrated in the drawings as so applied.

It should he explained that tho stencils referred to are usually about four and (mo half inches long by two inches wide; 'lhey comprise a central rectangular field of thin paper or similar material which is inelosed around its edge-portion hy two thicknesses of paper, and these in turn are inelosed at their edge-portion by two paste hoard. constituting a frame. The cenis adaptcd to he -noistened and when Written upon by a suitable machine the type punc' tures the paper or so reduces its thickness at the points of'impa'ct that it is rendered capahle of use in the. mannerof a stencil. That is to say. bypassing an ink roller over this thin field the ink will penetrate through the portions weakened or punctured by tho type and make an imprinton-qui envelop, card, or the like. placed beneath the stencil.

f'ihesc stencils are employed for addressing purposes. and are used by publishers, advertising agencies. large commercial houses. and the like, where thousands of pieces or addrcssedmail matter are sent out at ccrtain intervals. Hcretofore it has been customary.

to employ special machines for preparingthese stencils. the ordinary typcwritmg machine not being: adapted for this purpose/ That istosay. the platen of the typewriter being round the stencil is heat or curved transvcrscly-upon hcing written upon; and thiivcry often renders the, stencil incapable Specification of LettcrsiPatent.

of use in the automatic machines in which they are placed for the subsequent addressing operation.

According: to'onr invention the stencil may he readily inserted in an upright posi tion in the machine, and may be written upon and elevated for each new line hy turn i ing; the platen roll. in the ordinary manner, i

the stencil as a. whole being maintained throughout in an upright position and pre rented from being bent or curved in'cither direction. I

In the accompanying in; our invention applied thereto, the ribbon v drawings-Figure 1.. is a plan new of a typcwrlting machine havand rilalum-carrying mechanism being rc- I moved: Fig. 2 1s a \IQW in front elevation of the same; Fig. 2 is a sectional view on an.

means of turning; the m lled heads 8 mounts 'f ed on the. ends of the platen shaft. Ve will here state that all of the parts of the type writer shown are of the ordinary construction and only those parts will he referrcd tio in this description which are necessary to; make the a pplieation of our invention clear. 1

Fi e will further state that before using 3 onr'inrention in addressing stencils it is necessary to reniave the ribbon and ribbon guide. This is msrely'hy reason of the pan ticalar' construction of the machine under consideration. as the location of the ribbon guide in the commercial Underwood ma chine prevents the insertion of a stencil to the. requisite distance in a straight line.

The preferred form of our attaclnnent, as ilhistrated in Figs. 1.9. 2, and 3. will now' he described.

' per edge portion of the stencil to maintain.

The numeral 9 indicates a plate which is of the length of the carriageof the typewriter and is provided at its ends with slots 10 through which headed screws 11 are adapted to be inserted and screwed into apertures in the frame members 6 at opposite ends of the carriage. At the front of the plate 9 there is a depending flange portion 12 which is vertically-disposed with its lowr edge located in close proximity to the surface of the platen roll 7. This flange 12 acts as aguide, and as a support for the upit in a vertical position at all times while it is in the machine. Mounted on the plate 9 are two similar guide plates 13, each of which has at the front vertically-disposed flange portions 14 which extend downward parallel to the flange portion 12 and serve as guides for the ends of the stencil. Each of the plates 13 is provided with a longitudinal sl 15 through which passes a set screw 16 which enters a screw-threaded aperture in the plate 9. The plates 13 are preferably I applied thereto an adjusting nut 26.

bent at a right angle at their rear edge to form a flange 13 which abuts against the rear edge of the plate 9 and thereby assists in maintaining'the plates and guides in correct position. By loosening the set screws 1.6 and adjusting the plates .13 toward or from each other the space between the guides 14 may-be lengthened or shortened to ac commodate various sizes of stencils or cards. The numerals 17 indicate two similar spring arms which are secured to the rear edge of the plates 13, as indicated at 18, and each of which is bent twice upon itself at substantially right angles to form a depending arm 19in the bottom or free end of which is journaled a feed roller 20 of rubber or like material. The rollers 20 are positioned directly opposite the platen roller 7, and in the horizontal plane of the axis thereof, and normally the spring arms 19 force these rollers into contact with the platen. Slidably mounted in sleeve bearings 21 near the outer ends of the plate 9 are two posts 22 each of which is normally pressed downward by a coil spring 23 interposed between a collar 2t thereon and the lower sleeve bowing 21. The upper end of each of these posts is screw-threaded, as indicated at 25. and plas 9 upper portion of the edge of the posts 22 is flattened at one side as indicated'at 27, and graduation marks 28 are provided on this flat side. The posts 22 are connected at their lower ends to opposite ends of av bar 29 which L-shapcd in cross section. the foot 30 thereof serving as a support for the stencil. VVhatsve have termed herein as the segmentbrace is shown in Fig. l, and indicated by the. numeral 31. In order to permit the sten- \CllS when inserted in the attachment to drop low enough to pcru t the maximum number of lines to be Written on the stencil field, we may! provide the segment-brace 31 with a longitudinal groove 32, which, in practice, extends a short distance beyond each side of the sector 4. This groove 32 is wide enou h to accommodate the bar 29 which norma y rests on the bottom of the groove. groove,,however, may be dispensed with, especially when the later model. of stencilcardis used, as with this type of card it is unnecessary to provide for the drop of the stencil-cards lower than the top of the seg ment brace. In order to move the feed rol l-. ers 20 a short distance away from the platen 7 to permit the insertion of a stencil we provide a flat bar 33 having cylindrical ends mounted in bearings 34 on the plate 9 and provided at one end with a push-lever 35.

The bar 33 extends under and in contactwith the horizontal portion of the 5 ring arms 17 and by pressing the lever 35 ackward the arms 19 are thereby thrown slightly outward permitting the ready insertion of the stencil between the guides 14, and between the rollers 20 and the platen 7, the stencil falling into the groove 32 and resting upon the foot 30 of the bar 29. lVhen the lever 35 is-released, the sprin of the arm 17 turns the bar 33 to norma In this position the field 38 of the This centers of the rollers 20. By manipulating the platen in the usual way, or by turning it by means of the milled heads 8, the stencil will be raised by frictional contact with the platen caused by the pressure of the feed rollers 29 on the stencil which pressure is in turn caused by the spring action of the arms 19. As each line is written the stencil is moved up the required space for a new line, and this continues until the entire number of lines, three. or four, have been written, when the stencil is removed and a new one inserted. If only three lines are to be written on the stencils the adjusting nuts 26 are turned to bring the 11 per graduations 28 in line with the top 0 the nut, which action raises the bar 29 agiven distance: and if only two lines are .to be written the adjusting nuts 26 are turned to which action r'uiscs iho bar 29 a still farther distance. but not somuch as to withdraw it from the groove 32 if the latter be employed, which then not only provides means for us bringthe lower graduation mark to position,

weenie accommodating the stencil in the machine, but also acts to maintain the proper aimemerit of the bar 29 with the guides i The plate 9 is recessed on its front side to form near its encls shoulders 39 which limit the distance to which the guide plates it may be separated. The springs 23 not only serve to maintain the bar 29 in a horizontal oosi tion, but they also permit the saicl liar or scribed, or to the use 0 our invention with an Underwood typewriter only except Where We have so indicated. in the claims.
