4 Claims. (61. -45) v This invention relates to a phototype composing machine for photographing and reproducing lines of printed matter upon a .sheet of sensitized paper or film. More specifically, it comprises a magazine with a plurality of slides containing complete fonts with means for withdrawing a plurality of selected type characters from these fonts in alined form by the action of a keyboard so' that successive lines of composition may be reproduced photographically. Means are also provided for restoring the characters to their original position in the magazine so that they may be again used. In my present invention, while the selected lines of characters are being photographed, the controls for a second line may be selected from the keyboard and these controls will become usable upon the completion of the preceding line.

It is an object of this invention to provide a composing machine of the class described, in which variable width characters in a justified line length are used so that the justified line may be photographed. Also means are provided for reproducing successive justified lines, one above the other, on the same film.

It is another object of the present invention to obtaindifferent sizes of reproduced type from a single size type which is withdrawn from the magazine. These different sizes are obtained by suitable photographing and film displacing means, which will be more clearly described in the following specification.

It is a further object of the invention to provide a phototype composing machine with a section having a plurality of slides containing complete fonts which fonts are disposed in a side by side relationship, with a second section of slides spaced apart from the first section so that different design fonts may be used in each section. This feature will add to the utility of the machine in that the machine may be adapted for use with any design of type.

In order to carry out the purpose of the invention in the desired manner, I employ several components, such as a keyboard, selecting mech-R anism, magazine,- character assembling means f selector pin clearing means, photographing means, character restoring means, and energizing and controlling means. These component parts will be taken up in the order named and a detailed description of the parts will be made, together with certain of their functions.

Keyboard Referring more specifically to the drawings,

a the numeral Ill denotes a portion of a suitable typewriter having a platen II and type bars l2,

'tate' the dog 40 function of the master key i! will be more fully described later.

A suitable length gauge 20 is placed in any convenient position where the operator may see the amount of space the selected characters will cupy in a line. Disposed below each key bar i is a plunger 22 which actuates a valve 23, said valve having an intake air supply line 28 leading thereto for conducting compressed air. Valves 23 also have communicating therewith, conduits 24 which have branch lines 25 leading therefrom, each of said lines having a valve 26 therein. Each line 25 suppliescompresse'd air to'a suitable cylinder 2'5 which, when filled with compressed air, will move plunger 28 downwardly and rotate lever 29 and'dog 30 in a counterclockwise manner to thereby rotate ratchet 3i and the associated shaft 32. This shaft has a gear 33 thereon which meshes with rack member 34, which rack has a pointer 34a integral therewith disposed in front of scale 35. A tension spring 36 normally tends to move the pointer 34a to the right inFigure 1, and against a suitable stop 3'] which is secured to the gauge by means of screw 31a. This stop is adjustably secured to the gauge so that the length of the line may be regulated. While I have only shown two cylinders 21 and their associated parts for operating the shaft 32 and the .associated'rack 34, it is to be understood that there is one of such parts for each basic width of character. For example, the characters in the mazagine are of variable width. In a normal font the letter "i is of six units width, the letter m eighteen units with, and other characters vary between these limits. Where characters have the same width of course, the same cylinder 21 can be used for controlling the gauge placement.

. In order to hold the indicating mechanism in traveling position, a suitable stop or dog 40 is provided which can be released at the end of a line by the air which is supplied to a cylinder 42 to cause the indicating mechanismto be likewise released and returned to new line position. One end of the dog 40 is held in engaged position with a ratchet wheel 3| by means of tension spring 43. In other words, when the line has been completed, air is supplied to cylinder 42 through air line 44. This air will actuate a plunger 45 and thereby roin a clockwise manner to release the escapement mechanism, at which time the spring 36 will cause the pointer '34a to return to the stop 31.

Selecting mechanism When a key bar I5 is pressed, the 'air pressure is transmitted from valve 23 through conduit 24 to a suitable cylinder (see Figure 11). cylinder has a suitable piston 5| slidably mounted therein with a pin 52 extending from said piston.

A compression spring 53 is disposed around the pin and normally tends to force the piston to the right in Figure 11. When air is admitted into the right-hand end of cylinder 50, the pin 52 is moved to the left which, in turn, pushes a short selector pin 55 to advanced position. a plurality of pins 55 are slidably mounted in a selector plate56 and when these pins are in a normal position the ends are flush with the lefthand face of the plate. It will also be noted by referring to Figure 1 that the pins 55 are alined in vertical and horizontal rows. The pins in the vertical rows of pins are disposed so that suitable magazine slides 58 can slide downwardly in front of'them when none of the pins are projecting beyond the face of the plate 56. Whereas if one This rotate in a counter-clockwise It will be noted that of the pins 55 is actuated as shown in Figure 11 the slide 58 can only fall until the lower end thereof engages the pin.

It should be borne in mind that there are as many vertical rows of pins as there are slides 58 and the number of slides equals the maximum amount of characters desired to be used in a single line The cylinders 5b are disposed in a suitable selector bar 60 which is mounted for vertical sliding movement in frame (see Figure 1). When a line is started, this bar till is disposed directly behind the first left-hand vertical row of pins 55 after which the bar advances laterally to the right a distance equal to the distance between the row of pins, for each character that is selected on the keyboard. This movement of the selector bar 60 to the right in Figure 1 is controlled by a suitable escapement mechanism. This escapement mechanism comprises a rack 62 upon which the lower end of bracket 63 is slidably supported. This bracket 60 carries selector bar 60 and its associated parts. A double acting dog 64 is secured 'to the lower end of the bracket 63 and is adapted mitted to cylinder 66 through supply line 12 to actuate the escapement dog 64. This will allow the selector bar 60 and its associated bars to move to the right, step by step,

under the tension of a suitable torsion spring 15 which spring normally rotates spool 16 in a clockwise-manner to wind a ribbon 11 thereon, and thereby pull the escapement mechanism along words, each time a key bar is depressed, the escapehient mechanism is allowed to move from behind one vertical row of selector pins 55 to the adjacent row of selector pins. While the selector is disposed behind each row, one pin is selected the rack 62. In other out of'the row.

I When the end of the line has been reached, supplied to a cylinder 80 as' depressing cams 215 and 212 (Figure 1). The admission of air will move a rack 82 to the left in Figure l and thereby cause the spool 83 to manner and pull ribbon 84 and the selector assembly to the left, at the'same timewinding the torsion spring 15. The rack 82 is connected to the spool 83 by means of pinion 82a and shaft 83d.

' It will also be noted that there is only one cylinder 50 for every two horizontal rows or pins 65; consequently, a suitable shifting mechanism must be provided whereby the selector bar 80 can be moved up or down and thereby be positioned behind the desired row of pins. The selector bar 60 has a rod 88 extending downwardly therefrom (Figures 1 and 11), the lower end of which has a piston 89 secured thereon which fits within cylinder 90. leading from cylinder Leading to cylinder 66 is a conduit 61' .through conduit 8| by any suitable means such 90-is a conduit 9|, the other end of which is connected to valve 92, said valve having a plunger 93 projecting from the upper side thereof and contacting the lower side of shift key bar I6. Air is supplied to the valve 92 by means of conduit 94. When the shift bar I8 is depressed air is admitted into cylinder 90 and thereby causes\ the rod 88 and selector bar 60 to move upwardly to a position where the upper horizontal row of selector pins 55 will be disposed directly in front of cylinders 50. It is thus seen that by providing such a mechanism, one cylinder can serve-to actuate two horizontal rows of selector pins. This shift mechanism is comparable to the shift mechanism of an ordinary typewriter, where, as it is well known, the shift bar is actuated so as to obtain a high case letter in the alphabet or some other suitable character.

Magazine Let us assume that the selector bar 60 has been moved from leftto right as previously described to select a suitable pin from each of the various vertical rows of pins 55 in the selector plate 56; The pins will be at various elevations and when the slides 58 which have been previously described are lowered, their lower ends will rest upon their respective pin in the selector plate. The slides 58 are placed in a side by side relationship and each one of the slides has a T-shaped portion 58a integral therewith which fits into suitable grooves in magazine frame I (see Figures 1, 4,5, and In the position shown in Figure 1, all of the slides are disposed in their uppermost positions, with *their tops flush, in which case a clamp bar IOI acts as a stop gauge for the bars and holds them in elevated position. It will be noted that these bars have a plurality of notches I02 therein which are engaged by the sharpened edge of clamp bar IOI only when the slides have been lowered. In order to release the bars 58 after a line has been selected by the selecting mechanism, it is of course necessary to move the bar IOI from beneath the lower ends of slides 58. Bar IN is pivoted as at I03 and a suitable compression-spring I04 is employed for normally forcing the bar to a supporting relationship with slides 58. "The release of this bar, that is its movement to a non-supporting position, is efiected by means of plunger I05, which projects outwardly from cylinder I06, said plunger contacting one end of the bar IN. This release is eiiected when air is supplied to the cylinder I06 through conduit I0'I. The release of the bars is actually effected immediately after a complete line is set on the typewriter I0.

By referring to Figures 4, 5 and 7 it will be noted that each of the bars 58 has a plurality of transversely disposed notches I08 therein, into which character bodies I09 are adapted to slide. As seen in Figure 7 when the character bodies are in their proper position the left-hand edge of the slide 58 alineswith the left-hand face of the character body. ,Each'of the character bodies I09 has a pair of .translucent members such as I I0 and I l I with characters printed upon them. In the present showing, the character on the upper member H0 is of a light face type, Whereas the character on the lower member III is of a bold face type. Since each of the bars 58 is identical and. carries an identical set of characters it is evident that upon the release of the supporting'bar IOI after a line has been typed, all of the character carrying bars 58 will be allowed to fall until they reach their respective pins 55, which have been pushed out from the face of plate 56 as shown in Figure 11.

Upon the completion of the previous line, a

suitable transverse elevator bar II2 will be in contact with the lower ends of the character bars 58 and in such a position to support these bars as they are lowered. The bar II2 has each end thereof secured to belts II3 which are mounted on pulleys Ill, said pulleys being disposed on transverse shaft 5. The upper end of the belts II3 pass over idler pulleys such as H6 shown in Figure 11. When it is desired to return the slides into the magazine the bar H2 is moved upwardly from the position shown in Figure 1 until the lower end'of the slides 58 are properly positioned within the magazine. This means for returning the. slide is effected by means of pinion H1 which meshes with rack I I8 which rack is actuated by a cylinder H9. When air is supplied to this piston through a conduit I the rack H8 is moved towards the observer in Figure 1 to thereby cause the bar H2 to move upwardly and restore the slides 58 to the position shown in Figure 1.

After a line of characters have been selected in plate 56 and it is desired to lower the various bars 58- to the desired elevation so that the slides 58 will rest upon pins 65 and the line of selected characters will be in the proper alinement, the bar IN is released from supporting position, which will allow the lower end of the slides 58 to ride upon the transversely disposed bar H2. The weight of these sliding bars'58 will overcome friction offered by the parts of the lowering apparatus.

In Figure 8, a plurality of bars is shown in their lowered position at which time it is seen that the following characters are in alined position, viz., A CAB C. In other words, the above letters are the letters which were selected and which are desired to be later reproduced. With the above mentioned letters in alined relationship, that is, with the slides dropped to a position where they will all .be in the same horizontal line, it is of course evident that the notches I09 in the various slides will also be alined; consequently,

the characters may be pushed laterally and condensed into a line of predetermined length. This transferring operation will be subsequently described, but it might be stated that it is necessary to move this assembly of letters from the various slides in order to perform the desired reproducing work. Special attention is called to the word ,space band body I which also .fits into a notch slides is provided in this bracket so that a different type face may be used, that. is a different magazine may be moved to the position that the bars 58 are positioned in the drawings. In order to move the bars 58' to an operative position suitable screws I are provided which screws are rotatably mounted in lugs MW in opposed sides of bracket I00; The screws I30 are threadably secured in lugs I3I, said lugs I3I extending from the sides of supports I32. A knurled nut I33 is fixedly secured on the end of threaded rod I30 ifi tionary and affords a surface upon which the.

lower end of the magazine slides which are not being used, may rest.

Character assembling means The lateral movement is effected by a projection I6 1 which is secured on the end of racl: I65. This projection is adapted to move into the alined notches IE8 in the bars (see lower portion of Figure 8) and engage the right side of the alined group of characters, after which the characters are bodily pushed transversely to the left, into the groove MI. This movement is continued until the extreme left-hand character A engages the stop I li, said stop being mounted upon screw I663. This screw is adjustably mounted in the end of the rack Ifidthereby providing.

means whereby the position of the stop can be varied, so as to determine the point of starting of a line of reproduced type.-

The-energy necessary to move the rack I45 and itsassociated projection MG to the left in Figure l is supplied by a cylinder which cylinder has a vertically disposed piston provided with a rack I5I, extending therefrom and engaging a pinion I52, said pinion being integral with another pinion I lit which meshes with the rack I 65. Whenever compressed air is admitted into the cylinder ISil through a conduit hid, the projection I44 is actuated to transfer alined characters from the slides 55 into the rack Mil where they are placed in position for photographing. A compression spring I55 is disposed around the rack I45, which 'springserves to return the rack I 45 and its associated projection to normal position as shown in Figure 1, when air pressure is released from cylinder I50.

The projection I44 has an upstanding pin I58 which pin is adapted to contact the right-hand end of line length bar I59 after the alined characters have been moved to the desired position within the rack I40 (Figure 1). The distance between the stop I41 and the right-hand end of bar I59 is the length of the line, and since word space bands I25 may be compressed to variable widths the overall length of the line can be maintained constant. The line length bar I59 has a slot'lfill therein which is penetrated by screws IGI. After the characters have been pushed to the left in the above described manner they finally assume the position as shown in Figure 9 in which position they are photographically reproduced.

Selector pin clearing means 58 have been lowered as to shoe the characters, the clamping member IIlI engages the notches Ind and holds these slides in position. After that, the pins 55 which originally limited the downward movement of the slide 58, must be restored to their normal position, that is with their ends flush with the front face of the selector plate 56. In order to accomplish this result, I have provided a projectioniflb on the lower end of each slide 58. It is seen that by referring to Figures 6 and 11 that the face "of this projection 5% which is adjacent the face of selector plate 565 is beveled. Therefore, when the selector plate 595 is moved to the left in Figure 1 or away from the observer in Figure 11 the pins which originally limit the downward movement of slides will be engaged by the beveled surfaces and pushed baclrwardly into the plate so that their ends will be flush with the face. Plate is moved to the left in the manner just described by means of a suitable eccentric I62 which is mounted on shaft I68, said shaft having a lever I66 on its other end, the free end of which is connected to the upper end of plunger I65 of cylinder I66. When air is supplied to cylinder 58 through conduit It 'I, the eccentric M52 is rotated to cause the plate 56 to be pushed to the left in Figure l thereby move the selected pins 55 beneath beveled projections 58b.

It is seen that this plate has plus I St extending therefrom which are slidably mounted in brackets I65. is forced against cam I628 by means" of compre sion springs IiIl. With the pins restored to their original position, a new line can be set up by the selecting means while the preceding line is being photographed.

It is to be noted that by moving the pin plate 56 the cam surfaces pass over the pins 55 causing them to withdraw into the plates. The motion of the plate 6 to the side about two-thirds the width or the slides 58 will carry the relative positions oi the pins even beyond the cam projection 5%. Since onlytwo-thirds of the bottom of the slides {58 will be limited by the pins (as noted by the detail of 58) it can be seen that I am free to re-select the pins into stopping position, but they will not be brought bacl; into interfer ence position until the past line and the slides 58 have been withdrawn.

Photographing means As previously stated, when the alined characters are positioned as shown in Figure 9, they are ready to be photographed. Therefore, a suitable ject through a space above and a space below the bar I40. I

Leading to the light source I75- are wires I18 and I88, the wire I being secured to a suitable brush I8I which'contacts commutator I82 and also contacting the commutator is a brush I83 to which is secured wire I84. A lens assembly I85 is provided and also a suitable film or other sensltized sheet I88 is provided upon which the characters are reproduced. Since the lens may be adjusted it is evident that a reduction or an The right-hand side of plate 58 screw being loosely mounted in bracket I89.

enlargement of the type may be had upon the film. 1

The lens assembly I85 has a screw I81 threadably secured therein (Figure 1) and pin I88 penetrating it, both members I81 and I88 being secured in the bracket I89. The

- bracket I89 is pivoted as at I98. It is evident that when this bracket is pivoted about this point that both the lens assembly and the film I88 are likewise rotated. It is necessary to rotate the film and lens to the bold line position (Figure 12) when the top character bearing members III! are photographed. When it is desired to photograph the bottom character bearing members III the film and lens are rotated to dotted line position. When it is desired to vary the distance between the lens I85 and the character bearing members, it is only necessary to turn the screw I81.

The film I86 is mounted upon rollers I9I and I92, both of said rollers extending from a common bracket I93. This bracket has a screw I94 threadably secured therein, the far end of said A pin I85 is also secured in bracket I89 and this pin loosely penetrates the lower end of bracket I93. When it is desired to vary the position of the film I86 relative to the character bearing members III) and III and lens I85, it is only necessary to manipulate the screw I94.

After the line has been photographed it is desirable to move the film I85 downwardly to a new line position, so that the succeeding line can be printed in its proper order. This is effected by means of a toothed wheel 200 whose teeth penetrate perforations I86a in one edge of the film. This wheel is mounted upon shaft 2M which also carries ratchet wheel 282. An arm 203is loosely mounted on the end of shaft 29 I, which arm carries a dog 294 for engagingthe teeth in the ratchet wheel. A shield 205 is provided and this shield may be adjusted so as to determine the effectiveness of the movement of arm 283 and dog 284. For example, the farther the shield 205 is moved in a counter-clockwise manner, from position shown in Figure 1, the less effective will be the stroke of the arm 283 and the dog 284. The arm 203 is oscillated by projects from cylinder;209. Air is supplied to this cylinder through conduit 2I9 when it is necill , 10). One end of the pin with the pin.

essary to move the film to a new line position. The time of admitting the air is controlled by cam 218 and valve 212.

Character restoring means After the characters have been photographed, it is necessary to return them to their original position within their respective slides 58.

order to properly return the characters to the right in Figure 1 and to release a character at each slide 58, a suitable pin 2I5 has been slidably mounted in one end of an arm 2 I6 (Figures 1 and 2I5 is adapted to project very slightly into the slot I4I .of rack I48, and of course, when the characters are in a position to be photographed, the pin 2I5 will be disposed to the left of all of the characters. With the pin 2I5 positioned to the left of the characters, it is evident that as the pin moves to the right, all of the characters will be moved as a unit along The memberZIB has a rack 2I1 integral, therewith, said rack being engaged by the upper side of a gear 2I9. This gear has integral therewith a smaller gear 229 which meshes with a vertically disposed rack 22 I the lower end also has a the a plunger 208 which clutch face 249 222. When air is supplied to this cylinder through a conduit 223, the rack 22I is moved upwardly and, consequently, the horizontal rack 2" is moved to the right carrying therewith the pin 2I5, which pin also engages the group of characters which have been photographed and proceeds to push them to the right. A spring 225 is mounted around the rack 2I1 and normally tends to hold. the pin 2I5 in an extreme left-hand position, but it is to be understood that when the cylinder 222 is in operation, the spring 225 is compressed.

The beveled end of pin 2I5 which is nearest the observer in Figures 1 and 10, is adapted to slide against one face of a bar 230. The pin 2I5 has a compression spring 23I confined therearound, one end of said spring being contacted by the member 2I8 and its other end by a pin 232. As the assembled line of characters are being returned to the various slides 58, it is very essential that means must be provided for dropping one character in each slide; consequently, notches 230a are so positioned in the bar 230, that the end of the pin 2I5 which is nearest the observer in the drawings will fall into one of the notches and release the character bearing body members I09 or I25 in their proper slide, after which the pin again rides out of the notch, causing the end of pin 2I5 farthest from the observer to again engage the left-hand side of the next succeeding member.

It will be noted that the body members I09 and I25 have beveled cavities I09a and I250. respectively therein to allow the inward movement of the pin 2I5 to engage another character body as the end of this pin ridesout from notches 2300. in the bar 230. It is thus seen that each time a notch 23011 is reached, cally released in a bar 58 (see Figure When the characters have been restored to their respeetive slides the spring 225 returns pin 2I5 to normal position and then the slide carrying bar II2 is moved upwardly by means previously described to restore the slide bars to the magazine bracket I80.

\ Energizing and controlling means Air is supplied to the various pistons 'by a suitable compressor 240, which compressor furnishes air to the compression tank 24I from whence various-leads branch. Compressor 249 is driven by shaft 242 which shaft extends from motor 243. The motor 243 also has a pulley 244 upon which belt 245 is mounted, said belt being also mounted upon pulley 248 on shaft 241. The shaft 241 is adapted to rotate constantly.

It is seen in Figure 1 that the clutch face 248 is provided which is adapted to engage another upon cam shaft 250. A compression spring 25I tends'to force the clutch faces 248 and 249 into an engaged position. The shaft 241 has a disk 253 thereon which disk is engaged by one arm of a bell crank 254, said bell crank being pivoted as at 255 to a support 258. The other arm of the bell crank 254 has a roller thereon which is adapted to contact side cam 251 which cam is mounted on cam shaft 258. A spring 260 normally tends to holdthe roller in engagement with the side cam. After the side cam 251 has on rolled beneath the roller, the bell crank 254 is rotated in a counter-clockwise manner, which will cause the latch 28I to engage the hook 254a to latch the clutch faces 248 and 249 in a disengaged position. The parts remain in this disengaged position while the characters valves are being selected in the pin board 56, but after the line of characters has been selected, that is the pins 55 pushed outwardly beyond the face of the board, the latch 26l is released to allow the clutch faces 248 and 249 to become engaged, after which the cam shaft 256 is rotated one complete revolution. Latch 269 is released by means of a plunger 284 projecting downwardly from cylinder 2%. The air line 266 connects the cylinder 265 to valve l8.

After a line has been selected by depressing the key bars 05, the button ll is pushed in Figure 1 to thereby cause air to be admitted to cylinder for releasing the latch 2611, this will allow the cam shaft 2% to make one complete revolution to carry out all of the above enumerated functions. At the same time air is also admitted to the piston 82 through conduit dd to release the latch do and allow the indicating mechanism and to return to normal posit; n. Air is supplied to the valve ill from the tank B ll bymeans of conduits Leading from the compression is a conduit 2? l which supplies air to a plu-ality of there being a valve for each one of the cams 2"]3, illi, 2W3, and 2V9. also there is a. plunger altill for each of the valves and these valves contact the above charmerated cams. During one revolution of the cam shaft 255i, all of the cams actuate their respec tive valves to perform the functions timed relation.

Operation of the apparatus is as follows After the operator has completed the typing of a line of composition upon the keyboard, he

immediately punches the master H, which causes the clutches 2G8 and 2 39 to engage and rotate the cam shaft 2% one complete revolu tion. During this revolution, the following mechanisms act successively in the order named.

O. Clamp bar ml. is then released by another ridge on cam 2.13, so that the bars 58 can be restored to the magazine.

P. Elevator bar H2 acts under the influence of cam 219to return slides to magazine.

Q. Clamp bar H is in a position to hold a bar within the magazine, cam 213 performing this function.

R. Cam shaft 250 is then released from the driving means thus ending the cycle.

The above enumerated operations are illus trated in Figure 13 and occur in successive order, the successive steps being indicated by the letters F' to R, inclusive, in Figure 13.
