JOHN A. ERKSON, OF PRATTSVILLE, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 538,902, dated May 7, 1895. Application filed July 19,1894. S i l no. 518,005. dramas.)
To all whom it may concern:
Be it known that I, JOHN A. ERKSON, a citizen of the United States of America, residing at Prattsville, in the county of Greene and State of New York, have invented certain new and useful Improvements in Linotype-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, and to letters of refer ence marked thereon, which form a part of this specification. 7
This invention relates to improvements in linotype machines, the object of the same being to provide a series of movable type-bars with adjustable types and means for adjnsting the types, moving them in alignment and taking an impression from the line so formed;
and the invention consists in the construction and combination of the parts, as will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a side view of the machine, partly in section. Fig. 2 is a plan view of a part of the machine. Fig. 3 is a front view of one end of the inachine, the keyboard and push-bars being removed. Fig. A is a side elevation of the upper part of one of the standards which support the impression-cylinder. Fig. 5 is a detail view of the apertured plates which guide the.
upper ends of the push-bars. Fig. 6 is a detail sectional view through one of the typebars and types carried thereby, and Fig. 7 is an end elevation of the traveling carriage.
A designates the frame of the machine which is suitably constructed to support a keyboard at its forward end, and is provided on each side near its rear end with an upright or standard A between which the line of type is formed and upon which are mounted the devices for taking an impression from the type.
Extending transversely across the lower part of the frame A and journaled in the side pieces thereof is a shaft B upon which is loosely pivoted a series of arms 0, and to the upper ends of these arms the type-bars O are rigidly secured at one end, the other end of said type-bars normally resting between the uprights A, the arms 0 being limited in their downward movement by a bracket a extending from the frame A. The type-bars 0' each consist of a curved bar having a longitudinal row of recesses c in which are located adjustable types D, the side walls c of the recesses being inclined inwardly from bottom to top,
, and the types being wedge-shaped and split at their lower ends so that when they are forced upwardly in the recesses they will be wedged therein and held projected by frictional contact. The characters 01 are formed on the upper ends of the types and the bifurcated lower ends d cl extend below the lower edge of the bars to provide for adjusting said types. \Vhen the type-bars are in their normal position the types therein are located immediately over push-bars E which are pivoted the corresponding type in its recess in the I type-bar and wedge it therein, for the purpose hereinafter set forth.
The upper ends of the push bars E are guided by fiat apertured bars F (Fig. 5)
throughwhich said push-bars are passed, spaces being left between the bars to provide for the passage of the arms 0 which support the type-bars when said type-bars are moved as hereinafter described. The bars F are joined to each other at their upper ends and are rigidly secured to the uprights A, extending rearwardly therefrom, as shown in Fig. 1. r
In order to provide a compact keyboard and a compact arrangement of key-levers each alphabet offinger-keys is arranged in a zigzag manner as shown in Fig. 2. and the corresponding key-levers are arranged in banks of three each positioned one bank above the other as shown in Fig. 1, the key'levers being pivoted upon rods secured at each end in brackets a depending from each side of the frame which supports the keyboard.
G designates a carriage which moves over the upper edges of the type-bars C and is provided with a shaft upon which is mounted a roller G the said shaft being connected at its ends to bell-crank levers g to the ends of the forward members of which is attached a cross-bar G while to the ends of the upper members are pivoted arms H by means of which the carriage is moved. The arms 1-1 are rigidly connected at their lower ends to the shaft B, and from this shaft extends an arm I? connected to the foot-lever I by a link i, so that by depressing the foot-lever the shaft will be rocked and propel the carriage. The cross-bar G is forced down upon the upper edges of the type-bars when the carriage is moved forward and will engage the types which have been projected beyond the upper edges of the type-bars and move them on a line between the uprights A so that an i1npression can be taken therefrom as hereinafter described. To bring the types and typebars to their normal position the foot-lever I- is permitted to raise a slight distance and the backward movement of the arms II will turn the bell-crank levers which lift the crossbar G and permit the projected types to pass beneath the same, and said types will be depressed in passing under the roller G as the type-bars fall back by gravity to their normal position.
K K designate a series of space-bars which are located between the uprights A upon a rod a which passes through slots therein, the lower ends of said space bar-s being connected to finger-keys K pivoted on a rod a These space-bars are adapted to beprojected between the type bars at intervals to form spaces between the words of the line of type, and therefore there are as many space-bars as type-bars, and the operator after spelling out a word on the key-board depresses aspacebar on a line with thelast letter depressed so as to move a space between that letter and the first letter in the nextword.
L designates a cross-bar which is adapted to be moved up under theline of type so that said type can rest thereon while the impression is being taken. This cross bar is provided with a longitudinal bore or rectangular recess Z therein through which a rod 0, extending between the uprights A passes, and the ends of the cross-bar L rest upon slides M which slide upon lugs a formed on the uprights. The slides M are connected by a bar M and are provided with upwardly inclined surfaces m upon which the depending portions of the cross-bar L ridewhen the said slides are moved inwardly by the operator pushing upon the connecting-bar M.
The device for taking an impression from the-line of type consists of a cylinder'N which is journaled in the upper endsof sliding bars 0 attached to the uprightsA'. These bars are attached to the uprights by means of bolts a which pass through slots 0 therein,and the lower ends of said bars are connected to footlevers P which are pivoted at their rear ends to the frame of the machine and are connected at their forward ends by a bar P. Upon the cylinder N is wrapped a sheet of papicrmach and when the foot-lever P is depressed the cylinder will be brought down upon the line of type to receive an impression in the papier mach, the depth of the impression being regulated by the length of the slots 0 in the sliding bars. When the impression has been taken the cylinder is returned to its normal position by a helical spring 0 which is connected at one end to a projection 0 extending from the sliding-bar and at its other end to an apertured bracket (1 on the upright. Upon the shaft of the cylinder N is keyed a ratchet-wl'ieel N with which engages a springactnated dog at for preventing back ward rotation of the cylinder, and to the upper end of the upright A is secured a spring pawl R which engages the teeth of the ratchet-wheel when the cylinder is depressed and turns the cylinder one tooth when it moves up to its normal position, thus presenting a new surfaceto receive theimpression from the next line of type formed between the uprights.
The sheet of papier-mach by this means receives the impression of one line after another, and when it is filled is removed and may be used to make a stereotype plate therefrom.
In operation the operator to form a line of type between the uprights A beneath the impression cylinder N depresses the fingerkeys (2' for the letters in the line commencing at the first alphabet on the left for the first letter, the second alphabet for the second letter, and so on, the push-bars being arranged with respect to the keyboard so that a pushbar in each series will project a type in the type-bar correspondingwith the alphabet on the keyboard--a space-key being depressed after each word to locate a space-bar between the type-bars. When the operator has de' pressed the proper number of keys he moves the carriage Gover the type-bars by depressing the lever I and as the carriage travels toward the uprights A the crossbar G thereof engages the adjusted types and moves the type-barsto' bringsaid adjusted types on a line beneath the cylinder N. The cross-bar L is then moved up against the under side of the typesby means of the slides M and the lever P is depressed which forces the cylinder N down upon the line of type to receive an impression in the papier mach wrapped thereon. When pressure is released from the foot-lever P the cylinder will be returned to its normal position by the spring 0 and the spring pawl R being in engagement with the ratchet-wheel N will turn the cylinder so as to present a new surface at its lower portion. The operator now allows the lever I to rise a shortdistancewhich moves the arinsI-I rearwardly turning the bell-crank levers of the carriage and lifting the cross-bar G. The type-bars will then fall back to their normal IlO position by gravity and in doing so the adjusted types passing under the roller C} will be depressed. The carriage is now permitted to move to the lower ends of the type-bars and the parts are then in position to form another line.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
