The front and rear end v walls 14: and 15 are'detachably' connected as by screws '16 at the front and rear margins of'the side Walls 11 and 12, as showniin Fig ure 1. Inasmuch as the side,,.front and rear; walls are preferablymade of cast aluminumL or other material, they maybe provided with openings of any approved nature, so to suitably provide supporting rails and reinforcing parts for said'walls'," necessary to mount the operating details of the machine thereon, as shown in the drawings.-

' The "shaft 0 rotataby bears' in the a e walls aura lower portions thereof betweenthe ends, extending 'j transversely"across f the spacefbetween the side wallsfofttlie frame,

and at the outersideof the side wall 12, said e shaft G is providedwith anoperatingcrank or handle 17, shown inFigureQFOf the draw:- ings, and also inFigure 1. This handle be detachably clamped? as by set's crew 18 upon said shaft.

The supply roll'of giimrned"tapfeE,is of course of th'e conventional type ,having a hub insert onwhich; the tape: is spirallyfwound the space between said side walls, and'has a hub of the supply roll E thereon, in a manner 'to any desired 'diameter, with the gummed surface facing inwardly. The means D for supporting the roll E is preferably located at the outer side of the rear wall 15, and prefthreaded socket 22. A. imilardetachableV bracket arm 23 is detachably connectedat 24 and 25 at'its upper and lowerends to the rear wall 15, as shown in" Figure 1 of the drawings, and at its outerend it is" provided with a hub portion 26 rotatably supporting thespindle portion 27Qof a detachable bolt or screw ,28 which is rotatably carried by the arms or brackets 20 and 23,111 the relation shown" in Figures land 2 of the drawings.-

The spindle ,portionf27 rotatably receives'the which is obvious; If desired, :thin ringshaped washers'ee may be provided at opposite sides of the hub 'portion of the supply roll E, and ,a spider-like member 31, having resilient arms is placed between the hubfpors J tion 26, andthe adjacent washer .29 to resist longitudinalmovement of the supply roll upon the supporting bolt or pin*28. vAs is shown in Figure 3 of the drawings therear wall 15 is provided with an opening through which the gummed paper or tape 8X7 tends downwardly at an acute angle to the horiz ontahandlbeneath a grooved wheel or pulley which is rotatablycarriedupon. a

shaft bearing at its endsinlthes ide wallsfll and 12 of the frame,below and alittle to. the

i rear of the operating shaft C. This wheel 35 hasside flanges which retain the paper in f position, and from the pulleythe paper is adapted'to extend forwardly and upwardly at an acute angle to the vertical, and over a platen'-'pl'a te or member 37'which isdetacnably connected to the sidewalls of the frame by screws 37, shown in Figure 1 of the drawings. A fshaft 39, shown best in Figure J8 of the drawings, rotatablyfb ears at the upper forward corner of the frame, in the side walls ll'and 12, and extends transversely across I frictional roller '40 keyed therewith, which indeed is part of the feed meansF. -'The uppierportion of this roller 40 lies above the top edge of the "platen 37, so that the gummed V tape or paper is disposed in a trained relation over the; top of the roller 40, and is trained between upper and lower guide plates 411 and 412,which"are connected to the frontwall of the frame, as shown in'fFigu-re 3, andprov'ide a longchannel or space 43, therebetween, thru which the paper or tap'eis guided, so, thatthelower gummed surface thereof maybe mois tened bythe means G to "be subsequently dee e ib d- ,T e s pply r011, nd h t vel at,

thepaper as, above'described, is located,and 'takes place at the right hand side of the frame, as can be seen from Figure 2 of the drawings.

An irregularcover plate is detachably provided for the top of the frame, having a forward end adapted to fit in a: channel groove the frame, as shown in Figure 8; the said 'coverplate, designated at 4:7 in the drawings,

and shown in position about to be opened in Figure 7, conforming to the upper configuration of th'e' machine, and at its r ear end being provided with an opening 18 through which a thumb nut49 may be extended to clampthe rear end of the cover plate onto the machine, as shown in Figures 3 and T. This prevents dust, dirt, and foreignmate rial'sfrom entering the, working parts of the machine. I V v A springpressedfollower roller 50 is provided, having reduced ends 51 which seat withinslots provided in bearing extensions or lugswhich project rearwardly from the upper portion of the front wall 1&, as shown at'52 in Figure 8 of the drawings. *This roller 50 rests by gravity in such position in the bearing extension 52 that its peripheral surface willbea'rupon and hold the gummed paper against the roller40 and insure the dispensing feed thereof. The follower roller 50 is provided with movable bearing portions 56,-operating on the spindle 51 in each of the recesses of the extensions 52, having springs 57 acting on the top thereof, which springs 46 in the upper portion of thefront wall of lie in such position that the cover plate 47 V will operate thereagainst and compress them 'so that the roller 50 will act in frictional engagement with the roller-40 or the guinnied paper carried thereby, for a purpose which is obvious. To center the springs 57 it is preferred to provide lugs 58 on the other sur.. faces of the cover Figure 7.

Referring further to the feed means F, a

sleeve 60 is keyed at61 onthe operating shaft C, having a radial extension "socket 62 in which an arm 63 is detachably keyed in any approved manner. Figure 1, and elsewhere,'has a racksbar 64 pivoted at its upper endbya pin 65, and the rack bar 6 1 is provided" with a series of teeth 65 on the under sur facether eo f, which terminate at a location 66, for afpurpose to be subsequently described. This arm 63 and the rack bar are normally held in a rearward position by a contractile spring 67*, which is connected to said arm 63 and to the rear wall of theframe, as-"shown'in FigureQL, This spring is also used to return the frame and the handle to a positionwhere the dispensing operation may, be repeated, Y The rack bar 64Loperates upon shaft f VVith the handle in the position plate 17, as shown in,

This arm 63, as 'shown'ina toothed .wheel 67, which is freely rotatable ongthe in Figure 9.

shown. in Figure 1, by pressing downwardly thereon, the shaft'Cwill be rotated and the arm 63 thrown forwardly, whichalso projects the rack bar 64 forwardly thru a suitable opening provided in the front wall of the,"

retaining extension 70, shown in Figure 8.

Referring to the printing apparatus H, a type supporting table is provided, which inwardly from the lower end thereof is provided with 'a passageway 81adapted toreceive the reduced spindle end 82 of an arm 83 which is radially and rigidly connected upon the sleeve portion ,60 ofqthe shaft C abovementioned, and as shown in Figure 5 of the drawings. or fran1e'80 is oscillative about the axisof the spindle 82, and at thetype supporting face thereof it is provided'with a lower type retaining flange 84, shown in Figure 5 of the drawings, and at opposite sides thereof it is provided with retaining. flanges 86 and 87,

shown in Figure 9 of the drawings, The

rows of type 88 are supported between these flanges, and a follower 89 engages against the same and is urged by clamping screws 90 to hold the type in position; the screws 90 being threaded in the retaining flange 86, as shown The type supporting frame is turned thru an angle of 180 during the dispensing opera-'- tion of the shaft C, between the ink pad 91 and the platen 37 said'pad 91 and platen 87 being disposed in a V-shaped relation downwardly converging towards the shaft C, and being relatively disposed at .oppositesides of a vertical plane to the-axis of the shaft C, as:

shown in Figure 3. The ink pad 91 is preferably-detachable, and held in place on suita' ble cross beams 93 detachably connected at 94 upon the side walls; the inkpad 91 being itself detachably connected between retaining flanges on these cross bars, by means of adjusting'screws 95, so that the pad thereof faces towards the platen in position to be engaged by the type when the spring 67 has pulled the operating parts back to their nor mal position. i r

Novel means is provided for guiding and reversing the type supporting plate or frame between the ink pad and platen, in a coop: erative action with the dispensing of the tape, to print on the ungummed surface-of The rackbar 64 is held from jumping off the toothed wheel by means of a I This type supporting plate the latter an advertisement or other indicia arranged upon the type carrying; frame.

This means preferably consists of an arcuate 'bar'100, shown in Figure 7 of the drawings,

whichis-relatively thin, and at the forward end hereof is laterally provided with Mia I extension 101, shown best in Figure 6 ofthe drawings, into which is detachablythrea'ded a pivot screw 102 which is pivotally carried by the side wall 11 of the frame B; This en,-

ables the actuate bar to" be swung upwardly, upon removal of-the coverplate -47,

as'shown inFigure 7 of-the drawings, so that easy access may be had towthe type supporting plate and other details for, arrangement of the type, and detachment of thetyp-e supporting plate. However, normally, the arcuated type plate controlling bar 100i's rigid with the frame B, and at. itsrear end. it is provided with a socket 104 adapted to re.-

ceive ascrew 105, which is threaded into ascrew threaded socket l06 in-the upper portion of the plate or crossbar 93 which can rice the pad 91. Theiba'r 100 when in this 7 position is of course concentric with the axis of the shaft C.-

The construction of the bar 100. best be seen from Figures 2and 4 of the drawings,

wherein it is shown that the same is nar- I rowed at an intermediate portion108, and

the end portions thereof are relatively wide and provided with front andrear slots 109 and 110 respectively, which open infacing relation at the narrow portion .108; the latter portion being disposed to the right side of the aligning slots 109' and. 110 This construcand 112 are reinforced byraisedcross braces i 117 shown in various figures of the ,draw-.

ings. On the narrow portion 108 of the bar i 100 is disposed a plurality of rack teeth 120,

which project into the extended l-ine o-fthe slots 109 and 110, scribed. v

a The type supporting the upper end thereof, has a passageway 122, axially aligning, with the passageway 81,

for a purpose to be deinto which detachably'fits a stub extension- 123, of a plate 124; the extension 123 being keyed by a set screw 125 rigid with the type carrying frame or plate 80, as shown in Figure 5. The plate 124, as-best shown in-,Fig

ures 4 and 5 of the drawings, is provided with a segmental arrangement of teeth 128,.thereon, through at one end of the plate124; said teeth beingarranged concentric with the axis'of theex-tension 123,:that is, the axis of oscillation of: the type supporting plate," On the uppersurface of the plate 124, spaced frame or plate; 80,;at

from the teeth 128 and at the opposite side of'the axis; of oscillation of the type sup-portingframe with respect to saidteeth, is dispos'ed an extension 130 which is adapted to ,slide back and forth in the slots 109 and 110 of the arcuated guide 100 above described. I 7

Referring to the operation of the printing and v controlling bar A details, it is to be noted that the normal in- 6 operative position of the type s pp in plate '80 is shown-in Figure 2 of the drawings, with the type thereof against the ink pad 91," and in this position of parts the guide extension pin 130 which is rigid-with thetype supportingplate or frame is positioned in'the rear slot 110 of the ai'cuated bar 100, rearwardly of the segmentally arranged teeth 120,'the latter facing forwardly in the line of the slots'109 and 110, as shown in Figure 2 of the drawings. Upon downward movement of the operating lever 17, the type carrying plate 80- will be moved forwardly and will be guided against turning from its-pad facing position, by the pin 130, which is disposed eccentric in the slot 110,

Wlth'IQSPGCt to the axis of rotation ofthe type-supporting plate or frame 80. as the lever is moved downwardlythe segmentally arranged teeth 128 will ride into engagement with the rack teeth 120 which are rigid on the bar 100, held in positionby arm 120 engaging the wall 11. At this same instant I Y the pin 130 ridesjoutof the slot 110, and the I a lever being moved downwardly will cause the type supporting plate or frame 80 to rotate on the spindle 82, shown in Figure 5 of the drawings, for 180 swinging the guiding pin 130- forwardly of the segmentallyarranged V tee'th'128, so that as the operation is continued 37, and as the operation is continued the type gage, on the ungummed face of the tape the segmentally arranged teeth 128 ride off of the rack-teeth 120 and the pin 130 enters the forward slot 109. The type of the type supporting plate now face towards the'platen or strip disposed over the platen 37 and impress the indicia thereonwhich it is desired that the ungummed surface of the tape shall operation, it is to he noted, that from the time the lever is moved to move the type plate off the ink pad, untiljust shortly before the type engage on the tape at the platen, the tapeis being dispensed at the front of I the machine. as above described. However,

just before the type engage on the-tape over theplaten 37, the rack teeth of the bar 64 will have ridden off the toothed wheel- 67 at the location 66, so that the paper is no longermoved over the platen, but is held stationary while the printing thereon is taking place. Of course, upon; release of the operating lever the spring 67 will return the parts to normal position above described.

4- )The moistening apparatus'G preferably In connection with this printing consists of a liquid receiving can'or'container 150, carried by a bracket 151' on the front wall 14 of the frame,'and'-which container 150 is provided with a preferably detachable top 153 upon the upper surface of which is exposed a Wick 154 which is bent into substantially U-shaped formation, with the ends depending into-the liquid in the container, and the bight of the wick projecting above the cover 153 and in thepath of the gummed o Attention is called to the fact that the throw of the lever will dispense a length of gummed tape, at a single operation, having one complete printed impression thereon; said impression being that which wasmade at the immediate preceding operation, aswill be quite apparent. Of course, any number of i the sections dispensed by successive throws or operations of the lever may be maintained in a continous strip, without cutting upon the knife 160, as will be quiteapparent.

' From the foregoing description'of this invention it is apparent that a novel gummed tape dispensing andprinting' machine-has been provided, which is relatively compact,

and the multiple operations of which are per- 7 formed by a single' movement of an operat-- .ing lever. The operations are automatic-and the printed impressions will be clear and not blurred, as would result if cylindrical type rollers were used. 7 In this machine the tape is stationary during the impressing of the type. V

Various changes in the shape, size, and ar-' rangement of parts may'bemade' to the form of invention herein shown and described, without departing from the spirit of the invention or the-scope of the claims.
