APPARATUS FOR JUSTIFYING SET TYPE;

SPECIFICATION forming part of Letters Patent No. 645,801, dated March 20, 190( Application filed October 12, 1899. Serial No. 7%,4'22. on model.)

T 0 all whmn it may concern;

Be it known that we, HENRY JAMES SYDNEY GILBERT-STRINGER, residing at 35 Tavistock Crescent, W'estbourne Park,- London, and FREDERICK WIoKs, residing at Halfway Lodge, Esher, in the county of Surrey, England, citizens of England, have invented a certain new and useful Apparatus for J usti-.

fying SetTypes, (for which we have applied for a patent in Great Britain, dated March 15, 1899, No. 5,632,) of which the following is a specification.

Thisinvention relates to simple means of justifying types which are set by composingmachines or otherwise.

, Instead of putting in the line of types spaces of different widths or spaces forwhich others have to be substituted in justifying we employ only spaces of unit thickness or multiples of the unit and never only one space, but always more than one to allow for one or more being ejected in justifying, while still retaining an interval between the'words. The line of set types and spaces is forwarded to the j ustifying mechanism, its length in units and the number of its space groups being indicated in the usual way. The operator, guided by these indications, sets suitable gages, which determine the movements of a pusher reciprocating once for every advance of the typeline. When-it meets a type, the pusher is stopped; but when its upper part can pass over the tops of the spaces then if the gage set by the operator does not stop it it pushes out one of the space-types.

Apparatus for operating as described is arranged according to our invention, as we shall describe, referring to the accompanying drawings.

Figure 1 is a front View. Fig. 2 is a plan. Figs. 3 and 4 are respectively left and right hand end views. Fig. 5 is a section of the ejecting-blade; and Fig. 6 is a front View of the adjustable slides, shown separately from the rest of the machine,

The machine shown in the drawings is sup-- posed to be placed at the left end of any suitable type-settin g machine,within easy reach of the compositor and it has an upper type-channel a, which takes the place of the delivery-channel usually employed in composing appzaratus, surmounted by a space-indica tor As these parts are of known construction and the space-indicator is worked in the wellknown manner from the space-key of the type-setting machine, it is to be understood that no claim is made in respect of those parts a and b. A spindle 0, caused to revolve by a hand or otherwise connecting it to a revolving spindle of the setting-machine, has fixed on it an edge-cam d and a face-cam e. The cam 01, acting on a roller on a lever f, causes that lever to reciprocate, moving a feed-slide gand a feed-slide h, connected to f through a rod i and lever The cam e, acting on a roller on a lever is, in each revolution moves back-that 'is to say, to the right in Fig. 3 and to the left in Fig. 4a cross-head Z, which is urged in the opposite direction by a spring on a sliding rod m, attached to the cross-head Z. Another rod n, attached to the cross-head Z, has pivoted on it a spring-pawl 0, which when it engages the teeth of a ratchet-wheel p, as will hereinafter be described, causes that v wheel to turn tooth by tooth, and a pinion g,

fixed on the axis of 19, also to turn. This pinion gears with rack-teeth on a slide 1', which has a projecting rib 4 and is fitted to slide along a fixed V-guide s, and in a recess on the upper side of the slide r there is another slide t, having also a projecting'rib 5. From the rear end of the sliding rod m projects a blade to, the lower part of which is of a thickness somewhat less than that of a unit spacetype, while its upper part which projects farther is nearly the thickness of two unit spacetypes.

A type-channelv has a slot cut through its sides for the passage of the blade at through it. The blade to is of such height that when there is a character-type facing it in the channel o the upper projecting part of the blade is stopped by the upper part of the type; but 7 when there are two spaces facing it in the channel the upper part of the blade .canpass over the tops of these, which are lower than a character-type, and the lower thin part of the blade can push thesecond space-type out through the opposite slot. A number of figured keys w are arranged to act on vertical sliding rods 00, which are urged downward by springs; On a horizontal rod y, fixed below the type-channel a, is fitted a slide ,2, having an index projecting up from it, pointing to graduations on a gage 1, which can be adjusted to various lengths of line and fixed by screws 2.

The apparatus is operated as follows: The compositor working the type-setting machine goes on until he sees that the types, (which are delivered into the channel a and are fed forward one by one by the reciprocating feeder 7b,) acting on a pin projecting up from the slide e, have moved that slide to the left until its index is somewhat beyond the zero of the gage 1. He'then knows that the composed line is longer than it should be by as many units as indicated on the gage. He also knows, by looking at the indicator 1), that in composing the line the space-key has made a certain number of strokes, or, in other words, that there are in the composed line so many groups of spaces between words, each group consisting of two space-types of unit thickness. He therefore knows that from this line must be removed as many unit space-types as the number indicated on the gage 1. If these space-types were all re badly justified.

and the gage shows that the length of the line is in excess by three units, the operator subtracting three from seven would know that of the seven groups four would have to be left each with both its units in it, and in order to give uniformity to the line he would determine to leave the two next the ends of the line untouched and to extract the three units from the three middle spaces. would therefore depress first the key 3 and pull forward the upper slide t, depressinga springbutton at its end, so as to stop against the rod :craised by the key 3. Then releasing the button of tand depressing key 2, he would pull forward the lower slide 1' until it was stopped by the rod of the key 2. ator having thus set the slides 25 and 1' moves the gage z and the indicator 1) back to their zero positions and goes on to compose another line.

pusher it they advance the previous line, for the justification of which he has made preparation. As each character or space type reaches the chute 6 at the left end of the channel a it drops into the channel 1; in front of the pusher g, which is reciprocating in unison with the pusher h. The types are thus advanced along the channel v. As the spindle c revolves, causing the cross-head Z, and with it the rods m and n, to reciprocate, the forward movement due to the spring on m is stopped by the upper part of the blade 10 The oper As the types of this line descend and are moved along the channel a by the meeting character-types in the channel y; but when the first pair of spaces present themselves the upper part of a can pass over them, the rods m and '12 making a longer forward stroke; but they are stopped by a tappet 3, projecting down from the rod at, meeting a rib 4E, projecting up from the slide 1'. The stroke, however, made by the rod 02. in this case is sufficient to move the wheel 19 one tooth around, and thereby to move the slide 1' a distance equivalent to one of the intervals between the key-rods 00. When the next pair of spaces present themselves, the same action takes place, the slide rbeing thus moved over another interval of the rods 00. As it had in the first place been moved over two intervals to the rightand has been moved back two to the left, the end of the rib at is now'in such a position that it is clear of the tappet 3, and therefore when the next pair of spaces present themselves to the blade to the rod on makes its full stroke, the lower part of the blade to ejecting the right-hand unit of the space. This is repeated when the next two pairs of spaces present themselves; but then the upper slide t, having moved with the lower slide throughthe three intervals at which it had been set, has been brought to such a'position that its projecting rib 5 forms a stop to the tappet 3 in the same way as the rib of the lower slide, and consequently when the next two pairs of spaces present themselves there is no ejection of their units.

In other cases where the number of spaces and units of excess length in the line vary the operator has to exercise his judgment as to which spaceshe should select for ejection.

If, for instance, there were five spaces and two units of excess length, he might eject from the second and third or from the third and fourth spaces. In this case he would stop the upper. slide i by the rod or key 2,

thus determining that two spaces have to undergo ejection, and he would stopthe slide '2' by the rod of key 1, in which case the second and third spaces would be reduced, or he would stop it by the rod of key 2, in which case the third and fourth spaces would be reduced. Y

Having thus described the nature of this invention and the best means we know of carrying the same into practical effect, we
