Abstract: 10,504. Dow, A., and Dow Composing Machine Co. May 6. Type, distributing. - Relates to distributing - machines of the kind described in Specification No. 26,636, A.D. 1896, in which nicked types (or matrices) are received singly in a series of carriers, presented to a series of warded channels, and automatically ejected into the proper channel. (1) Galley mechanism and means for separating the type matter into lines and the lines into single e types are shown in Figs. 1, 2, and 8. The galley 85 is provided with an adjustable aide-stick 88 clamped over a flange 89 on the galley and fitted at its free end with a spring latch to ex. tend over the shoulder 95 of the line elevator 94 and prevent the end types of the line on the shoulder 95 from falling. The elevator 94 carries up the front line into a channel formed by the elevator and a bar 100 pivoted at one end on the framing and clamped at the other end to a post 103. The type advancing in the galley is levelled by a roller 105 mounted in a recess in the bar 100. The galley follower 246 is provided with a low portion to pass under the roller 105 and is fitted with spring stops 249 for engagement with a cross-bar 251 sliding in. grooves 87 in the galley and connected by cords to weights. The cross-bar 251 is provided with handles 256 fitted with hooks 257 for engagement over pins 258 on the galley, so that the cross-bar 251 can be withdrawn over new matter placed behind the follower 246 and held while the follower is being adjusted behind the new matter. The elevator 94 is provided with a plate 260 and recess 261 for removing leads to a receptacle 259. The line follower 93 in the line channel 200 slides in guideways 92 in a bracket 91 under the action of a weight 155 and is fitted with a yielding head in the form of a finger 158 on a spring-pressed plunger 157 to obtain a quicker action. The line is advanced along the channel 200 to the typecarriers 35 and is levelled by a roller 201. As each type - carrier approaches the channel 200, fingers 206 extending across the end of the channel are moved to allow the end type to be protruded and transferred to the type-carrier, and are returned as soon as the type is removed by the carrier. The fingers 206 are on a slide 205, Figs. 2 and 41, actuated from a shaft 209 oscillated by means of a cam disk 223, Fig. 1, driven from the main shaft 3. Figs. 5 and 18 show means for reciprocating the elevator 94 and returning the line follower 93. The elevator 94 is connected by arms 150 to sliding blocks 152 engaged by crank-pins 149 on disks 148 on a shaft 106 driven from a gear-wheel 7 on the main shaft 3 through a gear-wheel 109 on a sleeve 108 loose on the shaft 106 and formed as a clutch member 113 for engagement by a sliding member 128 feathered on the shaft 106 and spring-supported in a cam 125 feathered and friction tight on the shaft. The member 128 is formed with a cam surface 141 for co-operation with a spring-projected bolt 136 to retract and positively stop the member 128 after one revolution, and a spring-projected bolt 137 prevents accidental displacement of the member 128. The bolt 136 is raised to release the member 128 by co-operation of a cam surface 147 on the bolt and a star-wheel 112 on a collar 110 feathered on the sleeve 108 and actuated by means of a fork 122 on a spring-depressed bell-crank lever 114 held up by a trip lever 117 operated by the line follower 93 and returned by a cam 121 on the shaft 106. The trip lever 117 has limited movement in a slot in the bracket 91 and is formed with a notch bevelled on the upper edge to co-operate with a bevelled edge of a notch in a spring-protected linelocking block set in the bracket 91 with one end in position to enter the line channel 200. Normally, the bevelled edges engage so that the trip lever 117 is held up and the line-locking block is retracted, but when the follower 93 strikes the lever 117, the latter is moved clear of the line-locking block, releasing both parts. The cam 121 returns the trip lever 117 above the line-locking block, and the spring of the lever 114 swings the lever 117 so that the bevels re-engage and the line-locking block is retracted. The line follower 93 is connected by a link 164 to a lever 162 pivoted at 163 and having an adjustable block-and-slot connexion with a lever 167 pivoted at 168 and provided with a cam roller co-operating with the cam 125, the connexion being such that the forward throw of the lever 162 remains constant. Over-throw of the lever 167 is prevented by stops 178, 179. 'Means is provided to hold the line follower 93 in the retracted pasition if no line has been fed by the elevator, and comprises a rack 188, Fig. 2, having endways play in the bracket 91 and engaged by a gravity pawl 192 pivoted on the follower 93 and slotted over a pin on the spring plunger 157, Fig. 1, so that if the plunger 157 is moved back by the presence of a line, the pawl 192 is freed from the rack 188, otherwise the follower 93 advances only to the limit of movement of the rack 188. (2) Type-carrier mechanism is shown in Figs. 1, 2, and 41. The type-carriers 35 are pivoted on a revolving disk 15 and have limited movement by springs 38 against stops 41, so that each carrier dwells in front of the line channel 200 while receiving the type. Each carrier comprises an arm 36 formed at the outer end with a curved heel 47 and a casing enclosed by a cover-plate 69 and slotted &c. to guide an ejector 49 and a sliding side plate 59. The type cavity is formed by a face 48 on the end of the arm 36, the inner face of the side plate 59, and the end of the ejector 49. On the cover-plate 69 is guided a casing 72 for controlling the plate 59 and the ejector 49, which are both spring-projected. The casing 72 is slotted to receive projections on the parts 49, 59, and is actuated by means of a roller 79 working in a cam-groove 81 in a fixed ring 82, and further, the roller 79 is engaged by a nose 218 on a lever 217 connected with the-shaft 209, when the fingers 206 are withdrawn, so that the plate 59 and ejector 49 are moved slightly further backwards to allow the type to enter the carrier with little friction and to allow large type to enter without coming into contact with , the ejector. In the normal position of the fingers 206, a type'is held protruded, as shown in Fig. 41, in position to engage the face 48 and arrest a type carrier, and in order to assist the spring 38 in returning the carrier against its stop 41 after receiving the type, a ring 197 loosely mounted in a groove 196 in the cover 19 of the disk 15 and connected to the disk 15 by springs 199 is provided with a series of lugs so that it is arrested by the retracted casing 72. (3) The types are carried in the carriers 35 past warded channels and are ejected into the proper channels by the ejectors 49 and forced entirely into the channels by means of cam projections 78 on the casings 72, the cam-groove 81 being plotted to advance the projections 78 so that the type is forced into its channel a distance proportionate to its thickness. The warded channels are formed by radial blocks 226, Fig. 2, and the channels are extended by walls 234 attached to springs 233 on a base-plate 230 and springs seated in slots in the blocks 226. (4) In order to reject any types which are set wrong way up, or for any other reason cannot be distributed in the machine, a nick-is provided inthe side of the type opposite to that containing the nicks for distribution, and this nick should register with a ward on the plate 59, otherwise the type will not be held squarely in the carrier and will be caught. by a projection 244 on an adjustable spring-retained pivoted plate 239, so that a passage 238 is opened for the escape of the type between the projection 244 and a projection 245 normally less than type width apart. (5) Means for stopping the machine is controlled by the typecarriers 35. The disk 15 is fitted with a spring plunger 24 for engagement with a fixed toothed ring 21 to stop the machine, but normally held retracted by a latch 29 sustained by an arm 33 of a ring 17 connected to the disk 15 by springs and provided with lugs 18 behind the type carriers, so that if the arrested typecarrierfails to move at once when struck byits lug 18, the ring 17 is stopped and the latch 29 released.
