HAND-OPEBATEI) BULLETIN-PRINTING MACHINE.

Application med ocmber '6, 192s. seriai Noesassr.

This invention relates to hand operated bulletin printing machines or devices for printing advertising and other matter,

though it is noted that the invention 1sl proved type wheel and carriage control and type spacing mechanism.

Another object of the invention is to provide an apparatus or'v device of this kind having improved type alining mechanism.

Other objects 4of the invention are to improve generally the simplicity, speed and efficiency of such devices and to provide a device or apparatus of this kind which is durable, economical to manufacture and operate, and which will notget out of order.

The inventive features for the accomplish- .ment of these and other objects vare herein shown in connection with an improved bulletin printing machine which, briefly stated, comprises a mainframe carrying a supply roll, a platen bar, and supporting rollers carrying a take-up roll loosely supported on the supporting rollers. Other rollers guide the paper from the supply roll to and from the platen and thence to the takeup roll. A carriage pivotal and slidable on a rail carried on the Jframe in turn carries a type wheel, and an index wheel operatively connected tothe type wheel. A handle extending from the carriage serves to rock the carriage and vpress the type to the paper, and at the same time actuate a pair of escapement teeth mounted o'n the carriage into cooperation'with a series of rollers mounted on a spacing bar to` advance the carriage. A ratchet on one of the supporting rollers is engaged by a/feed p'awl on a, line spacing lever for feeding the paper; while a detent pawl prevents retrograde motion of the ratchet, and a stop pawlprevents overv feed.

Other objects of the invention will appeal' as the description proceeds; and while hereinI details cf .the invention are described,

the invention is not limite-d to these, since manya-nd various changes may be made without departing from the scope of the invention as claimed.

In the accompanying drawing, showing by way of example, one of many Vpossible embodiments of the invention,

Fig. l is a front elevation of the machine; Fig. 2 is an end elevation;

Figs. 3 and 4 are side elevations showing different positions of the carriage;

Fig. 5 isan inclined fragmental plan showing the index wheel looking in the direction of the arrow of line 5 of Fig. 3;

Fig. 6 is an inclined sectional view, partly in plan of the escapement bar and rollers taken on vthe line 6-6 of Fig. 4:,looking in the direction of the arrow of said line; Fig. 7 is a side elevation partly in section showing a spacing roller; and.v i

Figs. 8 'and 9 are fragmental side elevations showing the ratchet and pawls.

The operative parts of my improved machine are carried'on a mainframe comprising a pair of end members 10 formed with widely separated feet 11 and a cross piece 12 slightly above the middle part, and provided with open bearing recesses 13 receiving a shaft 14 carrying a supply roll ot paper 15, pressed upon by a resistance roller 16 journalled in the ends of -links 17 pivoted to the frame, to prevent overthrow of the roll. `The paper passes over and under intermediate and lower paper guide` rollers 20` and 21 (Figs 2 and 3) by which paper is guided to and from the platen bar 22.

Uprights 23 on the top of the endmembers carry' a top roller 25 receiving paper from the lower roller'21 to form a display field 26 (Fig. 1). A pair of parallel sup-v porting rollers 27 and 28 (Fig. 2) are mounted at the upper part of the frame to the rear of, said field. The paper passesfrom the top roller under these rollers 27 and 28 to the take-up roll 29 which is merely loosely supported on the supporting rollers.`

on rail 31 mounted betweenI said members 10 above and to the rear of the platen carries a carriage frame34 fast on said sleeve A and comprisingr spaced frame members 35 and 36 (Fig. 5) in which is mounted a horizontalshaft 37 carrying atype wheel e5 'i A sleeve30 (Fig. 3) pivotal and slidable said pinion, and-also carries an index wheel 47 on the .spindle provided with indicating letters and characters 48a corresponding to the type 39. A pointer 48 is carriedon the said carriage frame and disposed over` said indicating wheel, for selecting the type to,

be rinted. j

handle 50 extending. from the carriage frame serves for rocking the type to the platen as in Fig. 4. A forward extension 51 4of said carriage frame comprises an ,upper member 52 and a lower member 58, to which latter is pivoted an inking roller casing 55 carrying therein an inking roller 56 pressing against the type. restoring elbow lever 58 pivoted 'at its elbow part to /the carriage frame has a lon arm 59, Fig. 3; provided with an end rol er 60 bearing against a .spacing bar 6l. A spring 63 tensioned between said casing 55 and the short arm of the restoringf lever holdsthe ink roller 56 pressed againstthe type and. said end roller 60 pressed against the spac ing or escapement bar 61 thereby to move the type wheel from the platen after printing has been effected. An alining pawl 65 pivoted on the carriage frame is acted .upon

y a spring 66 tensioned between a pin 68 on the pawland said -short arm, yw ereby the pawl is caused to engage between the teeth of the ,alining wheel 41 as the type is pressed a ainst the paper, thereby to alinel the type. detent finger 67 carried onfsaid elbow lever engages the in 68 when the type Wheel is retracted, to li t the pawl from the f teeth .'to permit the type wheel to turn to select another character.

A series of rollers 70 (Figs. 6 and 7) mounted on said spacin bar 61 cooperate with a pair of relative y offset inwardly pointed type spacing teeth 71 and 72 mounted on the lower face of said upper member 52 andl snugly disposable .between said p,

Said teeth have parallel advance rollers. and rear pos1t1omng faces 73 and 74 enaging the rollers, and beveled cam faces 6 and 77 engageable with 'the rollers re" spectively to advance the carriage a half space during the forward stroke, and a half space during the back stroke of the type wheel. The forward end 77 of the tooth 71 is pointed for the easy insertion of the tooth between the rollers when the carriage is oscillated from the position of Fig. 3 to that of Fig. 4. In the position of Fig. 8, the carriage ma be easily slid toward either end of the rail or wide spacing, paragraph` ing or display work.

A line spacing paper feed ratchet 78 (Fig. 8) fast on the rear supportingl roller 27 has abrupt teeth 79 engaged by a feed pawl 8() on a line spacing lever 81 loosely mounted on the journal of said rear roller.

A spring 83 compressed between vthe tail ofsaid pawl and a socket 84 of the lever yieldably holds the pawl in engagement with the teeth. A detent pawl 85 pivo'ted4v on the main frame lprevents retrograde motion of the roller; While a stop pawl 86 engaging the advance faces of the teeth for preventing over feed, is providedwith a tail 88 engageable by a lifting finger 89 on the lever to hold the stop pawl disengaged from the ratchet as the feed pawl moves lto its most retracted position (Fi 8) and advances the ratchet a short distance, whereupon the finger 89 releases the stop pawl for engagement with the crown of the tooth ready to engage and stop the next tooth when the paper has been fed one line space, as in Fig. 9. j-

The operation of the devices very simple, and obvious from the foregoing.

- The supply roll 15 is put in place, the paper threaded up'as in Fig. 2 and started on the take-up roll 29. The carriage is then slid laterallyy to near the point where the first letter is to bewheel rotated by han thus inking the type rinted and the index 'until the character to be printed is opposite 48. The handle 50 is then forced down by hand, thus forcin the pointed end 77 (Fig. 6) between the ro 1ers 70. Continued downward movement of the handle carries the tooth 71 past the rollers and brings the camV face 77 into camming engagement with the roller 70, moving the carriage a half space just before the type is pressed to the paper. This movement brings the alining wheel 4l into engagement with the pawl 65, thus slightly rotating the type wheel, if necessary,

and ahningthe type accurately.

rllhe handle 50 is then released, and on the return stroke, the'cam face 76 is brought intocamming engagement with ,a spacing roller, thus spacing the carriage another half letter-space. rl`he above operation is repeated until a Word is spelled rlhe space between the Words is obtained either by sliding the carriage to the right without oscillatingv it, or by repeating the above described operation, except that the type is not brought into contact with the paper. f

After'the line is completed, the paper is fed a line space for the next line merely `by drawing the lever 81 toward thefoperator to the'position of Fig. 9, whereupon the end members; a platen thereon; a rail shaft mounted between said vend members above and to the rear of the platen; a sleeve pivotal and ,slidable on said shaft; a carriage frame fasten said sleeve and comprising spaced frame members one of which has upwardly radially alined bearings a horizontal shaft mounted in the mid part of the frame; a type wheel on said shaft provided with peripheral type, and comprising a bevel pinion; a spindle in the radial bearings; a bevel gear on said spindle engaging said pinion; an indicator wheel on the spindle provided with indicating letters and characters corresponding to those of the type wheel; a pointer carried on. the said carriage frame and disposed over said indicating wheel; ahandle extending from the lcarriage frame for rocking the type to the platen; and spacing means to advance /the carriage.
