AUTOMATIC PUMP-LOCK AND DEAD-LINE KILLER. FOR MONOTYPE-MACHINES.

Specification of Letters Patent.

Application filed April 26, 1910.

Patented Nov. 10, 1914. Serial No. 557,659.

To all whom it may concern:

Be it known that 1, JAMES W. PYLE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Automatic Pump Lock and Dead Line Killer for Monotype-Machines, of which the following is a full, clear and exact description. 1

This invention relates to certain improvements in that form of monotype casting machine commonly known as the Lanston, and relates more particularly to the controlling of-the pump and the galley trip rod. In the operation ofuthe Lanston machines as now manufactured, it often happens that the keyboard operator makes a mistake in a line and discovers the mistake before completing the line. It is then necessary for him to complete the line with Xs or any other character and justify the line. He then begins again and writes theline as he desires to have it. When the perforated strip goes to the casting machine, the end of the strip which was perforated last enters the casting machine first and the good line,

as well as the spoiled line, is cast. It is then necessary for the operator of the cast ing machine to pick out the entire spoiled line and throw away the type. If he does not do this, the galley-proof will show the good line as well as the spoiled line and unless the spoiled line is noticed by the proof-reader, it will eventually appear in the paper.

The object of my invention is to avoid the necessity for completing a line after the key-board operator discovers he has made a mistake and to avoid the necessity .for east ing the spoiled line. By means of my improvement timeis saved at the keyboard and at the casting machine, and the necessity for picking out and throwingaway spoiled or dead lines will be avoided. In order to secure this object, I provide means whereby the justification wedge lever which formerly gave the galley trip rod its longer stroke, will give said trip rod its shorter stroke, and whereby the justification wedge lever which gave the galley trip rodits shorter will give it its longer stroke. I also provide means for locking the galley trip rod against return movement after its shorter stroke, and until it is given its longer stroke, so that the pump will remain locked and no type will be cast while the galley trip rod remains at the end of its shorter stroke.

Reference is to be had to the accompanymg drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures and in which I'have illustrated a portion of a monotype machine having my improvement applied thereto. I

Figure 1 is a vertical section through a portion of a machine and illustrating the galley trip rod and, pump trip tube and the mechanism foroperatingthe same; Fig. 2 is a vertical section through a portion of the bed of the machine, showing'my retaining pawl applied thereto; Fig. 3 is atransverse-section on the line 33 of ig. 2; Fig. 4 is a side elevation similarto a portion of Fig. 1 but showing the galley trip rod at the end of-its longer stroke; v Fig. '5 is a top plan View of thegalleytrip rod in its normal position; Fig. 6 is a view similar to Fig. 5, but showing the galley trip rod at the end of its shorter stroke; Fig. 7 is a view similar toFigs. ,5 and 6, but showing the galley trip rodat the end of its longerstroke; and Fig. 8 is 'a'portion ofarecord strip perforated for use with my improved attachment. I I. 1 I One form jof monotype casing machineto which my invention may be appliedis partly illustrated in Fig. 8 of the patent to Bancroft, No. 674,374, granted May 21, 1901. In this form there is employed a galley trip rod 8Dv mounted within suitable guides'and movable longitudinally. Adjacent one end of this galley trip rodis the trip lever 5F, mounted to swing upon the trip lever fulcrum screw 46F. The end of the trip lever is disposed in the path of the galley trip rod and it carries a plurality of set screws, by

means of which the normal position and the time of contact with the galley trip/rod may be controlled. The opposite end of the K trip lever serves for controlling the line hook, as is well understood by those familiar with this typefof machine. The galley trip rod at its opposite end, is rigidly conneoted to the galley trip rod member 9D, to

which is mounted the rock lever 9D This rock lever'is pivoted intermediate its ends upon a fulcrum pin 9D and swings in a horizontal plane. .Pivotally mounted above the rock lever 9D are two justification f wedge levers 13D and. 14D,.each having a depending portion adjacent its corresponding end of said rock lever. Each justification wedge lever is pivotally' connected to a justification wedge lever arm rod 15D the I ing pin lever 16E. Adjacent the pivotal support of the two justification wedge levers is the air pin block 3D, within which are the air pins 11). Pivotally supported a'djacent each air pin is a bell crank 4D, one end of which is in engagement with its corresponding air pin and the other end of which serves to swing its corresponding rod 15D into or out of engagement with the centering pin lever. As a justification hole in the record strip passes the air outlet, air is permitted to pass to the corresponding pin 1D and the corresponding rod 15D is swung into engagement with the centering pin lever 16E. The upward movement of the latter raises the corresponding justific'ationwedge lever and the depending end of the latter engages with the corresponding end of the rock lever 9D to swing the latter. The rock lever is prevented from swinging on its pivot any great distance as'the opposite end strikes the other wedge lever, and the further swinging of the rock lever causes a bodily movement of the rock lever and a corresponding longitudinal movement of the galley trip rod 81). I

Substantially parallel to the galley trip rod 81) is a pump trip tube 49D, slidable within suitable guides. Ihis pump trip tube has a collar -ft9D thereon, which is normally out of engagement with a pump latch 33H (see dotted lines in Fig. 1) but which may be moved into engagement with the when thepump trip tube is moved lengthwise to the required distance. For moving this pump trip tube a lever 48D is pivoted to a portion of the frame of the machine, and has its lower end adjacent the rear end of the pump trip tube. The depending portion of thegalley trip rod arm. 9D engages with this lever LSD intermediate the ends of the latter, so that as the trip rod 8D is moved lengthwise, the pump trip tube will be moved lengthwise in the same direction to move the collar LQD from the position s'hownin dotted lines at least to the position shown in solid lines thereby locking the pump out of action.

All of the structure so far described was in use prior to my invention and is here explained only to facilitate a clear understanding of m invention. The operation of these parts and without my invention being applied thereto, is substantially as follows: l/Vlien the rod 15D is moved into position to operate the justification wedge lever 13D, thelatter'engages with the end of the galley trip rod rock lever 9D and the galley trip rod is given a forward stroke due to the engagement of the rock lever with the other wedge lever. When the other rod 15D is moved into operative position, the justification wedge MD is operated and the galley trip rod is given a forward stroke. The lengths of the strokes differ and the stroke produced by the justification wedge lever 13D is longer than the stroke produced by the justification wedge lever 14D. The forward movement by the justification wedge lever 14D, that is, the shorter stroke, operates to lockthe pump by the engagement of the collar 49D with the pump latch 331-1 The longer stroke produced by the justification wedge lever 13]) not only locks the pump but also operates the trip lever 45F.

One feature of my invention is the means for giving the galley trip rod its longer ;stroke upon the operation of the justification wedge lever 141) instead of by the jusl tification wedge lever 13]). In order to accomplish this, I provide the rear end of the galley trip rod with a hook X This hook has an eye through which the galley trip rod extends and it is locked rigid in respect ,to said galley trip rod bysuitable adjust- ;able lock nuts X forming an adjustable stop for the trip rod.

The hook extends into engagement along the upper surface of the galley trip rod arm 91) and the upturned or hook end is in the path of the justification wedge lever 14D. Thus, when said justiiication wedge lever is moved into [engagement with the rod lever 9D the 'movement of the latter about its fulcrum pin is limited by coming into contact with the hook X and the lever is caused to move forwardly bodily with the galley trip rod. latter to lock the pump against operation A second feature of my invention is the means'employed for locking the galley trip rod forwardly at the end of its short stroke and preventing its return until after it has performed its long stroke. This mechanism includes apost X which is rigidly. secured to the galley trip rod at its forward end and extends outwardly laterally therefrom. This post may move into or out of a recess X in the frame of the machine, and at the outer end of the post is a pawl X This pawl is free to swing in a vertical plane and is normally drawn down to a limiting position by a spring X Rigidly secured to the bed of the machine adjacent the outer end of the pawl, is a stud X having upwardlyextending side branches X between which the pawl X extends. The pawl has a depending lug X on its under side and two oppositely=disposed projections X extending outwardly upon opposite sides thereof. The stud carries a vertically-movable pin X normally pressed upwardly by a coil spring X and into the path of the de pending lug X. The two side branches X have inwardly-directed cam lugs X, as

shown particularly in Fig. 2, and beneath which the projections X may travel. The stud X is held in position by a nut X while the pin X islimited in its movement by a combined guide andlock at the lower end of the stud. As shown, the lower end of the stud is provided with a transverse slot X and the pin X has two lock nuts ment of the pin under theinfluence of the also serve as stops.

spring, and thus these guiding branches The operation of the mechanism is substantially as follows: The parts are normally in the positions indicated in Fig. 5,

that is, the free end of the pawl rests upon the upper end of the pin X and the two justification wedge levers 13D and 14D are out of engagement with the rock lever 91). Upon the operation of the justification wedge lever 13D, which is the first lever to operate in the normal running of the machine, the parts are moved to the position shown in Figs. 1 and 6, that is, the galley trip rod is given its shorter stroke and this stroke forces'the projection X of the pawl X against the pressure of the pin X and past said pin so that the pawl and pin interlock preventing the galley trip rod returning. At the same time projections X are brought beneath the cam lugs X so that the pawl cannot swing upwardly. It is thus evident that the galley trip rod is positively locked against return movement, and as the galley trip rod cannot return, the pump trip tube 49D cannot return and the pump is locked against operation but the galley trip has not been operated by this shorter stroke. Upon the operation of the justification wedge lever 141), the parts are moved to the position indicated in Fig. 7, that is, the galley trip rod is given its longer stroke by reason of the engagement of the rock lever 9D with the hook X and the projections X will be carried beyond the farther side of the camlugs X Thepin X raises the pawl to such a position that as the galley trip rod returns the projec tions X will ride up over the upper surface of the cam lugs X and the galley trip.

rod can freely return to the position indicated in Fig. 1.

By means of my improved mechanism, the

keyboard operator when he finds that any portion of a line has been incorrectly recorded on the perforated strip and he does not want this defective line to be cast on the casting machine, can prevent this casting by depressing any of the justification the opening 0 is reached.

keyson the lowerjustification key row on the keyboard. After operating such key he re-records the line as it should be in its proper shape and properly justifies it by the operation of the two justification keys. When the perforated strip is fed to the cast ing machine, it travels in the reverse direction from the direction of travel'during the perforating operation. Thus, when the portion of the paper upon which the incorrectly recorded line is found, reaches the air open-- ings, the opening produced by the key of the lower key row on the keyboard, admits air to operate the justification wedge lever 13D, and this gives the galley trip rod its short stroke. The galley trip rod is locked by my improved mechanism, and the pump is also looked against operation. As the paper continues to pass through the machine the pump will remain locked until an opening appears in the paper which was produced by a key of the upper key row on the keyboard, which will give the galley trip rod its longer stroke and release the same and re lease the pump trip tube For instance,'in forming the record strip shown in Fig. 8, the openings would be formed in order, beginning at the upper end and going to the lower end. The openings a and Z) would'be produced in the justifying of the previous line, not shown, and the openings 0 and d would be produced in justifying theline extending over the center portion of the' 1 strip shown. After justifying this line, the operator begins the next line and in recording it, he may make a mistake by the s'trik ing of the wrong key or otherwise, and he would then punch the hole'e. The striking of the key which punches the hole 6, would reverse the keyboard and put itin normal position ready to begin the line over again.

In feeding thestrip to the machine, the lower end of the strip reaches the air open.- ings before the upper end, and as the air flowing through the opening a locks the pump, the latter will not be released until Having thus described my invention, I claim as new and desire to secure by Letters Patent:
