PRINTING MACHINE.

Application med `.mnuary l25, 192e. ser1a1 No. 83,451.

This invention relates to oiiice printing machines primarily adapted for printing on envelopes, cards, tags and the like. The primary object of the invention is to provide a simple and efficient means for enabling ready change of the printing characters or a portion thereof as desired. More particularly it is an object to provide a segmental type holder carrying arcuate lines madev up of individual type, means which will not complicate the segmental holder being provided to retain the lines inv place and allow their removal for the purpose `of quick change of the form setup; and generally it is an object to render the construction simple and economical in manufacture and etlicient and durable in service. y

My printing machine is well adapted for cancelling stamps, as it is adapted to operate equally well on articles of various thicknesses arranged indiscriminately. The machine however may with advantage be put to other uses.

A. convenient embodiment of my invention is illustrated in the Vdrawings hereof, and is hereinafter more fully described and the essential characteristics are summarized in the claims. i

Fig. l is a front yelevation of my printing machine; Fig. 2 is avertical cross section, as indicated by the line 2 2 on Fig. l.; Fig. 3 is a vertical longitudinal section,as indicated by the lineB-S on Fig. 2; Fig. a is a detail of the inking roller and its support,-being a verticalr section on the line 4 4 on Fig. 2; Fig. 5 is a detail illustrating the support of the paper detecting lever, being a vertical section. on the line ll-l on Fig. 2; 6 is an `elevation illustrating the detector coni trol 'of vthe eccentrically Vmounted platen, being a vertical section on the line 6-.6 on Fig. l looking toward the right; Fig. 7 is an enlarged vertical cross-section of the rotary printing member, as indicated by the line 7 7 on Fig. l; and Fig. 8 is a. detail illustrating a system loi latches for retaining the removable printing lines, being a section substantially on the line 8,?-8 on Fig. 7 but partly broken away.

rl`he frame nf my machine is shown as ccnsieting ejf a pair of uprightend plates i0 il, a connecting front cross plate L?.

and certain cross rods. Journalled in the end plates is the main shaft 20 on which is' that it may give back from the platen according to dilferent thicknesses of material fed between them. The drawing shows an eflicient means for accomplish-ing` this, which however is not claimed in this application, but in my preceding application No. 30,658 filed May 16, 1925. As shown, I mount a double arm 24 and 25 having a hub 22 to the other end of which is secured a disk 23, as by screws.- The segment 30 near one end has an inward ear 31 which liesbetween the disk 23 and the arm 25, and a pin 32 occupying these parts pivots the segment to the rotatable member. I j f Y To a block 33, rigidly bolted to the inner face of the segment near its other end is pivoted a rod 34 which extends `loosely through a head 35 'carried by the rigid arm 24. Nuts 36 on this rod limit t-he outward movement of the segment while a compres sion spring 37 surrounding the rod between a head 38 thereon and the ,head 35 yieldingly holds the segment lin printing position but allows it to give back according to the thickness of the material fed between the segment and platen.

yThe segment is provided with overhanging parallel rails 40, providing Vundercut channels adapted to retain grooved type T. To allow the type to be readily slid into place between the rails and locked therein, I provide the mechanism shownin Figsj? and v8, comprising a'system of latches for the respective channels between the rails.l As there shown, l mount a series of'blocks 422 in thespace 43 between the segment proper and a radial portion of the block 33 to which the rod Se is pivoted.` Eachof these blocks position.

or with the transfer tool which delivers the type or receives it from the segment. When a block 42 is pressed inward (as shown in the c ase of one block in Fig. 8) the corresponding channel is free and the type row, or a portion of it, may be installed orremoved, after which the block returns to loclr it to At the other end of the channels I prefer to mount a stop 48 shown as an L- shaped bar of metal held by a screw 49. 'The construction described enables the type to 'be very readily changed.

lTheplaten 52 with which the segmentcofacts is shown as a long roller mounted on the shaft 5 which isl connected by gears 60 and 61 Vwith thev segment shaft 20. l have shown arhand crank 65 mounted on'a. stud at one "end ofthe machine and carrying` a gearg meshing with a gear 67 on the segment shaft, and this is a convenientway of driving the machine by hand power.

I have shown mechanism preventing the operation of the machine when paper is omitted. y p

`As shown in Fig. 3, the platen shaft 50 is mounted at one end adjacent the segment eccentrically lin a bushing 7 0 which is rotatably mounted in the frame member l0. On

'this bushing is-an'arm 7l 6) pivoted to a flat bar 73 slottedabout the segment shaft 20. "This bar carries aroller 74 coacting with a cam 7 secured to the segment disk 23. Accordingly, each rotation of the `segment `shaft turns the eccentric to raise that' end of the platen into vposition to be active, this being the position shown in Fig. 6. As there shown, the platen is raised, while theprinting segment 30 is out of registrationv with theplaten. Now, unless the paper' detector acts b y reason of the presence of paper, the cam will pass beyond the roller and the slide will'be freed and the spring '76' thereonwill restore the platen to idle position.

The paper` detector mechanism comprises alglever or finger 8O pivotally mounted on a 'longitudinal rod 8l and connected with a roclarm 82 which is adapted'to'be'ar against a dog 84 pivoted at 85 to the frame ofthe machine. The upper end of this dog stands normally opposite, but free from, a notch 7 8 in the slide-70, being retained in this position by aspring 86. When no paper is present, the (detector mechanism described is idle.

The 'finger 80 it will be noticed', extends shaft 8l.

into a peripheral groove 54 in the platen, so that it is impossible for paper to be fed to be gripped above the platen without raising the lever. Then the linger isso raised it rocks upwardly on the arm 82 which thus roclrs the dog into the notch 7 8; thereafter when the cam 75 clears the roller 74,

the slide cannot return to its normal downposition but is held by the dog, and thus the .platenis maintained in its active position throughout the time the segment is moving past the platen whereby printing is effected.

.To prevent jamming ofthe parts and allow the linger 8O to be raised at any time irrespective of the position of the notch 78 with reference to the dog 84, l connect the dog tripping arm 82 yieldingly with the detector linger 80. As/shown'in Fig.' 5,the detector arm is pinned to a hub-'87 on the Pinned to the other endet ythis hub is a short rock arm 88 which is connected by a spring 89 with'the dog-operating ,l

arm 82.vv This spring 89, is stronger than the spring S6 acting ony the dog. Y ltrwill be seen that if the detector, arin 80 is raised at a time when the notch 7 8 is opposite the dog 84, the two armsSS and 82 act a unit, swingingythe Vdogfinto the notch. If however, the detector yarm fis raised at any other time the spring 89 is constrained, forcing the dog against the edge of the slide 70 so that it will pass into the notch as soon as the notch comes oppo- Vsite the nose of the dog; l

In the interest of simplicity, Iprefer te provide the eccentric bearing described for only Vone end ofthe platen. find I' can eifect this by allowing a slight looseness of. lit of theplaten shaftvwithV its bearing in the standard 1l. rThe platen shaft is parallel with the segment shaft when theplaten is raised'into active'position, and the slight divergence from parallelism' whenV theQpl'at-Vl en isinactive is immaterial.

Fig. 2 illustrates a. simple elasticv stop limiting thel hand-fed sheet untily it is gripped by the segment andplaten. This elastic stop comprises a spring 'linger -100 mounted on a frame rod lOl and a cooperating spring pressed lingerJQ- mounted on a frame lrod 103. rlhis latter finger is preferably pivotally mounted on a bloclr 104 which is adjustably clamped tothe rod by 'a screw 105;" A spring 106 mounted in recess in the block forcesthis linger against the linger 100.V A suitable reeess'@ in the platen accommodates the engaging ends of these fingers.` A' "r i The paper is normally'ied by handalon'g the paper table 10S until stopped by the engaging ends et the lingers '100 and 102'. In this same movement, the forward edge of the paper raises the detector arm 80 which thus, by the mechanism already described, operates to hold 'the platen in its raised po- CII sition, after it has been raised by the'cam mechanism. Thus the paper may be advanced by hand at any time, and, at the proper time, it is picked up by the machine, fed throughit and printed; while it, for any reason paper is absent, the printing member and platen remain out of contact.

Figs. 1, 2 and 5 illustrate a convenient paper ejector. This comprises a roll 110 on a frame rod 111 and a surmounting roll 112 carried in the sheet metal cage 115, pivote-d on the rod 81. This cage is pressed down- Wardly by a spring 118 which is mounted within the cage has one end anchored to the rod and the other to the cage.

To ink the segment I have illust-rated the telt roller 120. This is `shown as comprising felt disks mounted on a hub 121 which has a hollow bearing sleeve 112 mounted on a stud 123. This stud is carried by a block `124 mounted in a recess 15 in the inner face of the frame member 10. The block is slotted and a pin 125 passes through the slot and through the frame member and has on its end a wing nut 127 to lock the parts together. Thus the block may be adjusted toward or from the printing member, bring ing the inking roller into proper position with reference to the segment, and the wing nut then locks the parts in this adjusted position. I may replace the inking roller without changing its mounting, by vsimply removing a pin 128 from the stud 123 and sliding off the complete inking roller.

Having thus described my invention, I claim 1. A printing member having adjacent overhanging parallel rails providing an undercut channel between them, a slidable block, and a. spring normally maintaining it opposite the end of the channel, said block being movable to allow access to the channel.

2. In a printing machine, the combination of a printing member parallel undercut type channels on the ace of the member located close to each other so that all may hold a unitary form, and a series of adjacent, individually movable locking blocks one for each channel.

8. In a printing machine, the combination ot' a printing member, parallel undercut type channels on the face of the member, a series of locking blocks one for each channel, and a series of springs for maintaining said blocks normally across the ends of the re spective channels.

4. In a printing machine, the combination of a rotary carrier, a segment adjacent its swinging end thereon pivotally mounted at one end and having on its convex face a series of arcuate parallel undercut type channels,

signature.

and a series of locking blocks one for each channel movably mounted on the segment.

5. In a printing machine, the combination of a revolving segment, parallel arcuate rails mounted on the Jface thereof and having overhanging edges, a stationary abutment at one end of the channels as provided, a series of individual abutments at the other end comprising slidably guided blocks having pins connected therewith, and slidable in the openings in the carrier, and spring surrounding said pins and pressing the blocks toward the ends ot the channels.

6. In a printing machine, the combina-tion ot' a` rotary carrier, a segment pivoted therein, a spring for pressing the segment out- 'wardly, parallel arcuate rails mounted on the face of the segment, a series of individual blocks slidably guided substantially radially on the segment adjacent the ends of the channels, springs pressing said blocks normally into position to overhang the channels, there being clearance enabling the blocks to be pressed inwardly against the action of the springs to free the channels.

7. In a printing machine, the combination of a carrier having an undercut channel in which a row oi grooved type may be mounted, a movable end gate for the channel, a spring pressing said end gate in a direction toward the plane of the face of the type, and a stop to limit suoli movement of the gate, the gatel being movable aga-inst the action of the spring to free the type.

8. In a printing machine, the combination of a carrier having parallel rails providing adjacent undercut type channels adapted to hold rows of individual type to make up a Ytorm, and individual means for locking each row independently on the carrier, said means being movable to tree such row.

9. In a printing machine, the combination oi' a printing member having parallel rails with overhanging edges adapted to hold between them rows of grooved type, individual gates at t-he end of the respective rows, each gate comprising a slidable block carrying a guiding pin, springs surrounding the respective pins for forcing the blocks outwardly and lips on the blocks limiting the outward movement.

10. In a printing machine, the combination of a. segmental type carrier having on its convex face a series of parallel channels, and individual end gates for the respective channels, means for holding them across the ends oi the channels and means enabling them to be moved inwardly, substantially radially, to release the channels.

In testimony whereof, I hereunto aihx my HENRY o. osBoRN.
