- Application filed 0ctoberi26, 1926. Serial No.- 144,272. 1
This invention relates to typographical machines of the general class disclosed in Letters Patent of the United States, No. 436,532, wherein circulating matrices are released from a magazine in predetermined order and then composed in a line, the line then transferred into a vertically movable first elevator or matrix-supporting memher which presents it to the mold, whereupon the mold is filled with molten metal to cast a type-bearing slug against the matrices, and the matrices thereafter returned through a distributing mechanism to the magazine.
In the operation of machines of this character, the composedv line of matrices is presented to the mold in accurate and predetermined relation, and if the intended operating relationship or alignment between the mold and the composed matrices is inadvertently or otherwise impaired, then the mold would collide with the matrix-supporting member and damage the machine and cause a faulty delivery or squirt of the molten metal. I
An objectof this invention is to provide means in typographical machines, "of the class known underthe trademark names Intertype or .Linotype, for automatically stopping the operation of the machine when the composed line of matrices is improperly aligned, or if there is a misplaced matrix or other extraneous object lodged between the mold and the composed line of matrices or thefirst elevator.
lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention. herein disclosed may be made within'the scope of what is claimed without departing from the spirit of the invention, or sacrificing any advantage thereof.
The invention has been illustrated in its preferred embodiment in accompanying drawings, wherein:
Fig. 1 is afragmentary vertical sectional view taken through a line casting machine, showing the invention applied thereto; I
Fig. 2 is a similar view, but depicting allot/116i Operating phase of the invention;
I 3 is a fragmentary detail View of the usual clutch operating mechanism;
Fig. 4: is a perspective'view of the invention per se; j i
Fig. 5 is a fragmentary detail view of the safety device as it is attached to the moldslide; and
Fig. 6 is a similar view to F ig, 1, but depicting the safety device as detached from the mold disk. i
Referring to the drawings, in which similar numerals refer to similar parts throughout, there is shown the usual main frame 10 in which the mold slide 11 is slidably mounted. The mold disk 12 is journaled to the mold slide, as indicated at 13, and the usual molds 1d are secured to the'front or outer face'of this disk. i
In order that the matrices may .be' properly alignedwith the mold, they are as-.
sembled in jaws 15 carried by the first ele- 'vator 16, which is mountedfor vertical sliding motion; This elevator '16 is positively elevated during the operation of the machine by operating components, not here disclosed, and it descends by force of gravity. The height at whichthe descent of the first elevator 16 is stopped is determined by the set screw 17 and an alignment stop bar 18, which baris slidably mounted in the cap 19 0f the vise frame 20. Stop pins 21 extend upwardly from the upper faceof the bar 18, and when the bar 18 is sov positioned that a selected pin 21 is in vertical alignment or registration with theset screw 17, the face of the set screw engages the stop pin 21 and arrests the descent of the first elevator, so that the assembled matrices are positioned in correct' alignment for accurate presentation. of the mold; This phase of device is well understood in the art and is disclosed in U. S. Letters Patent No. 1,439,586.
If the sliding alignment stop. bar 18 should be inadvertently set to permit the-first elevator 16 to descend to a lower level, and
the mold disk were positioned to present a 'la-rgeor so -called head letter mold to the matrices, then the mold would collide with the jaw 15 of the first elevator 16, or with the matrices, and thereby damage the machine. In order to obviate the possibility of injury to the machine, in event of the erroneous setting of the alignment stop bar 18, or if a misplaced matrix or other object should fall between'the mold and the first elevator jaw, or between the mold and matrices, I have provided the following safety means:
The usual hand lever is fulcrumed intermediate its ends to a bracket of the machine by means of a stud 26, and the lower or inner end of the lever 25 is pivotally secured to the upper end of the lever or member 27, which may be termed the mold slide lever, by means of a pin 28. A roller 29 is operatively secured to the lever 27 in termediate its ends, and this roller is received within the arcuate recess or notch 30 formed in the rear portion of the mold slide 11. There is provided a depending lever or member 31, which may be termed the cam lever, and this lever is fulcrumed to the lever 27 by means of a pin 32 at a point intermediate the upper terminal or lever 27 and the roller 29. A roller 33 is operatively secured to the cam lever 31 at a point intermediate the ends of this lever, which rolleris operatively received within the cam groove 3e oi. the usual mold cam 35. An arm 36 is pivotally secured to the lower end of the lever 27, as indicated at 37,tand the lower end of this arm is bifurcated to straddle the pin 38, which is rigidly secured relative to the machine frame. A second arm 11 is pivotally secured to the lower end of the lever 31, as indicated at 42', and extends downwardly to a point immediately adjacent the arm 43 of the usual bell crank lever or clutch operating member 4A, which is fulcrumed to the machine frame, as indicated at 15. Another arm 46 of the bell crank 4 cooperates with the collar 47 carried by the clutch shaft 48 to operate the usual machine clutch, which operation is common and well understood by those skilled in the art, and is clearly disclosed-in Figure 1 of United States Patent 661,386, granted November 6, 1900 to J'. R. Rogers. The arms 36 and41 are operatively connected, through the instrumentality of a lint 50,
which link has its opposite ends 51' and 52 pivotally secured to the arms 36 and 4-1 at points intermediate the terminals of these arms andadjacent their pivotal connections 37 and 42. d
' The depending lever or member 31 is provided with a transversely-extending recess 53,in which a plunger 54 is slidably mounted. This plunger is pressed by a helical spring 55 into engagement with the lever 27 at a point adjacent the roller 29, thereby normally urging the lever 31 to move about its fulcrum away from the lower portion of the lever 27. The upper or fulcrum porion of the lever 31 is bifurcated to straddle the lever 27, and a stopplate or strap 56 is secured to the front edges of these furcations and cooperate withthe lever 27 in a manner to be hereinafter disclosed.
movement of levers 27 and 31 the lower end of the arm 36 is held against movement by the pin 38, and inasmuch as the armlfll is operatively secured to the arm 36 by means of the link 50, it will work in approximate, parallelism with the arm 36' and consequently maintain the lower end of the arm 41 in constant'relationr to'the clutch crank arm 43 during the normal operation-ofthe levers. However, if the first elevator alignment stop bar 18 should be'erroneously set, thereby permitting the vfirst elevator to, de-. scend to the lower level, as shown in Fig, 2, while the mold diskis positioned to present a high cap or head letter mold to the matrices, then, as the mold disk'moves forwardly, the mold will collide with the rear jaw of the. first elevator, asshown. When this occurs the spring'55 will yield and permit the depending lever 31 to move forwardly without imparting further for ward movement to the lever 27. As soon as the lever 31 moves forwardly relative to the lever 27 the lower end of the arm 41 moves rearwardly and engages the arm 43 of the bell crank, thereby disengaging the usual clutch members 60 from the cooperating band 61 and stopping the operation of the machine so that no injury is caused to the matrices or to the machine. f 5 Again, if a misplaced matrix or others traneous object should be inadvertently po--; sitioned in'the normal path of travel of the mold, or be lodged between the mold and the first elevator or the lineof matrices, then the presence of such matrix or extraneous object would check the forward movement of the mold disk beforeit had'reached its normal stopping point and thereby operate the de-v scribed safety device and eflect the stoppage of the machine. I In machines. of this character it is frequently desirable to move ,the mold disk in dependentlyof its driving cams or associate ill) loo
mechanism, and in this construction this detaehment is brought about by merely moving the handle 25 downwardly, in theusual way, and this downward movement of the handle 25 causes the entire safety device'comprising the lever 27, depending lever 31, arms 36 and 41, and link 50 to be raised, thereby withdrawing the roller 29 from its receiving or cooperating recess 30, so that the mold slide may be moved at will independently of the lever .27. WVlieii the safety device has been detached from the mold slideyas described, the lever 27 is limited inits movement away from the lever 31 by means of the strap-56, andthisstrap also engages the.
lever.27 and moves it rearwardly when the i'oi' automatically engaging and operating the clutch operating means to stop the operationot' the machine when the normal move ment of the mold slide is interrupted. I
