Similar parts are designated by the same ref erence characters in the several figures.

The present invention, in its preferred embodiment, is shown in the accompanying drawings as applied to a typographical machine of the well known class hereinbefore referred to, 1 representing the usual assembling elevator which receives matrices and spacebands delivered from their respective places of storage in the machine as by manipulation of the keyboard of the machine in the usual manner, 2 represents the usual reciprocatory line delivery carriage thefingers'of which receive the matrix line from the assembling elevator when the latter is lifted, as usual, the line delivery carriage being movable toward the left in its guides 3 to carry the matrix line through the usual delivery channel 4 into a channel formed between the front and rear jaws 5 and 6 carried on the upper end 'of the line transporter or usual so-called' first elevator 7 when the latter occupies its normalor line receiving level in alinement with the delivery channel 4, the inner sides of the jaws 5 and 6 of the transporter having rails 8 and 9 on which the lugs on the upper ends of the matrices and spacebands rest whereby they are suspended in the transporter or elevator. The line transporter '7 is slidable vertically in guides 10 on a vise frame 11 which constitutes a part of the frame of the machine, as usual, and, as usual in machines of this class, the line transporter, after receiving a line, is lowered to the casting level to introduce the line between the right hand and left hand jaws 12 and 13 of a vise which serves to clamp the line endwise and hold it in casting position in front of a mold in which a type bar or slug is cast in the usual and wellknown manner against the matrix line, after which the line transporter is lifted to an upper level as shown in Fig. 1 where a 'reciprocatory line transfer slide 14 operating in a guide 15 in the machine frame and carrying a finger 16 operates to remove the line from the line transporter to p the usual transfer channel 1'7 from which the matrices are removed and conveyed to the matrix distributor and'the spacebands used in the line are returned to their usual place of storage, as in the usual and well-known manner. After removal of the line from the line transporter, the latter descends, in the usual manner to its normal or line receiving position.-

The right hand vise jaw 12 is retained in its normal open or line receiving position by a latch 18 which may be pivoted at 19 on the top of the vise frame 11 and engageable with a notch 119 in the upper side of saidjaw when the latter is in its normal or line receiving position, this latch having an arm 20 which lies in'the path of the end of one of the jaws of the line transporter andengageable thereby, as the latter approaches its lower or casting level whereby the latch is actuated to release the jaw 12, and this'jaw, which is slidable inthe vise frame 11, is movable inwardly or toward the left hand jaw 13 to close against short matrix lines or lines shorter than the line measure for which the machine is set, the jaw 12 being thus closed by suitable means as for example by a jaw closing arm 21 pivoted on the machine frame 22 and operated at ap propriate intervals from a suitable moving part of the machine as disclosed in my prior application Ser. No. 612,349 filed May 19, 1932, the

lower end of this arm being operatively connected by a link 23 to a slidable bar 24, the latter being connected to the movable right hand jaw 12 and acting to move this jaw inwardly or toward the jaw 13 after the line transporter has descended to its casting level and has introduced the matrix line between the vise jaws, and to return the jaw 12 .to its normal line receiving position after a cast has been made. The left hand jaw 13, which is usually adjustable in machines of this class for full lines of differentline measures, may be provided with any suitable adjusting means for this purpose, such for example as the jaw setting device 25 which conforms substantially with that shown and disclosed in U. S. Letters Patent No. 1,108,758 granted August 25, 1914.

The improved line stop provided by the present invention comprises preferably a pair of parallel bars 31 which are connected at their outer ends by a cross member 32 and slidable longitudinally in guiding grooves 33 formed in the inner sides of the jaws 5 and 6 of the line transporter," these bars of the line stop having only a slight friction in said grooves in order to offer minimum resistance tothe closing movement of the right hand vise jaw 12 when such jaw moves inwardly from its normal line receiving position shown in Figure 3 toward the jaw 13 to confine the line of matrices M which is shorter than the distance between the jaws 12 and 13 for which the machine is set in order to quad out such short matrix line. The stop rests against the first or end matrix in the line when the latter is lowered into position between the vise jaws and the closing movement of the right hand jaw 12 shifts the short matrix line toward the left until it closes against the left hand jaw 13, and during such shifting movement of the matrix line toward the left, the line stop moves with the line into the position shown in Figure 4.

Since the closing movement of the jaw 12 and the consequent shift of the matrix line against the jaw 13 is sudden and the shifting movement of the line is" arrested suddenly by the engagement of the matrix line with the jaw 13, the line stop, under the propelling influence of the shifting matrix line and by reason of its slight friction in its guiding grooves, would overthrow or ment with the jaw 13, thus leaving the first or end matrix in the line free to become dislodged from its compact position against adjacent matrices when the matrix line is lifted from between'the vise jaws, incident to the usual upward movement of the line transporter after the cast, unless means were provided to prevent such overthrow of the line stop. The means provided by the present invention for preventing such overthrow of the line stop comprises a suitable abutment on one of the vise jaws, such as the vise jaw 13, against which the line stop may rest when driven toward that jaw by the line when shifted underv the influence of the movable vise jaw. In the preferred construction shown, one of the slide bars 31, preferably the front one,

. of the line stop has its inner end bent or turned inwardlytoward the jaw 13 to form a prong or hook34 at the inner or matrix line engaging end of the line stop, and the jaw 13 is provided adjacent to its line engaging face with a vertical recess 35 into which the prong or hook 34 may enter, this recess forming a vertical shoulder '36 which serves as an abutment against which the prong or hook 34 may rest. By this construction, when the line of matrices M is shifted endwise in the transporter under the influence of the closing movement of the jaw 12, the line stop shifted by, the line of matrices will be stopped by the engagement of the prong or hook 34-there on with the shoulder or abutment 36 on the vjaw 13, and overthrow of the line stop will betherebyv prevented, the line stop however being retained in the position to which it has been moved by the line so that it will stand against the first or end matrix in the line until the line ofmatrices is removed from the line transporter, the line stop thereby serving effectively to prevent dislodgment of the end matrix or matrices in the line, due to vibration of the machine and the stopping of the line transporter at its upper position and also serving to prevent dislodgment of such matrix or matrices in the line when the machine is set to permit the transporter-tore turn the same matrix line to casting position for a recast therefrom. When the matrix line is removed from the line transporter by the line transfer slide 14 and the line engaging finger 16-thereon, the line stop is returned to its extreme right hand position ready to be advanced again to the left by the next incoming line, and the line stop may be automatically returned to its extreme right hand position by the line transferring movement of the line transferslide 14 which may be provided for this purpose with a dog 37 arranged to act upon a lug 38, which may be extended upwardly from one of .the slide bars of the line stop, substantially as shown in Figure 1.

The operation of the machine, provided with the improved line .stop hereinbefore described, is as followsz-Assuming the line transporter occupies its normal line receiving position with respectto the line deliverychannel 4 and the line stop 30-occupies its right hand position tov which it was brought by the operation of the transfer slide 14 incidental to the removal of a line from the transporter as shown in Fig. 1, the delivery carriage 3 operates in the usual and well known manner to introduce a line of matricesand spacebands into the right. hand end of-the channel formed between the jaws 5 and 6: of the'transporter, the first or end matrix at the forward end of the line engaging the right hand end of the line stop and advancing it more or less toward the left, according to the length of the line. While the line stop rests in this position against the forward end of the line and is retained in this position by the frictional engagement of the slide bars 31 of the line stop in its guiding grooves 33, the transporter descends in the usual and well known way to lower the line to the casting level, the right hand end of. the line descending at the inner face of the right hand jaw 12, which is then held in its normal open or line receiving position by the latch 18, and the line stop remain-, ing in engagement with the left-hand or forward end of the line, as shown in Fig. 3. As the trans.- porter approaches the.limit of its descent, one of the jaws thereon engages the arm 20 of the latch 18 and swings the same from its jaw holding position shown in Fig. 1, to its jaw releasing position shown in Fig. 2, the consequent release of the right hand jaw permitting the jaw operating arm 21, which is then set into operation,-to move the right hand jaw 12 inwardly or toward the left hand jaw 13, moving with it the matrix line until the forward or left hand end thereof strikes the inner face of the left handjaw, and such movement of the matrix line shifts or ad- .as shown in Figs. 4 and 5.

very freely or with very slight friction and the line is advanced very suddenly by the movable jaw and its advance is arrested abruptlyupon striking the left hand jaw. "After the-vise jaws have been operated to clamp, the line and the casting mechanism has operated to cast a-type bar or slug, in the usual and well known manner, the transporter rises and lifts the matrix line from between the-vise jaws and elevates it to the upper levelwhere the usual transfer slide 14 operates in the well known manner to remove the line from the transporter to'ithe" usual transfer channel 17 from which the matrices areconveyed in the'usual manner to the'usual matrix distributor and the s'pacebands are returned to'their usual place of storage in the machine, and during the line removing operation of the transferslide 14, the dog 3'7 thereon engages the upwardly projecting lug 38 on the line stop and returns the latter to its normal right hand position ready to meet the next incoming line, as shown in Fig. 1, the transporter, after the transfer of the line therefrom, descending in the usual manner to its normal line receiving position. I

During the lifting of the matrix line from casting position by the ascent of the line transporter, the hook or abutment 34 011 the line stop will disengage from the left hand jaw 13 by upward movement in the vertical recess 35 therein, but the line stop will remain-in engagementwith the forward or left hand end of the line, it being maintained in such position by 'its frictional engagement in its guiding grooves,and the line stop will thus servetdeifectively prevent squabbling or other displacement of the end matrix or matrices at theleft handend of the line suspended in the line transporter, due to the usual vibration. of the machine or other causes, while the line is being elevated to the transfer level, -and also while the line transporter is operated to again lower the line to casting position, as is sometimes done, to make a recast from the same line.

7 Setting of the left hand or adjustable vise jaw 13 in different'positions for different line measures will correspondingly set the abutment shouljder 36 thereon, thereby automatically determining the limit of movement of the line stop when advanced by the matrix line, to accord with the position occupied by the adjustable jaw.

It will be apparent from the foregoing, that the present invention provides a line stop for the line transporter or usual first elevator of a typographi- "cal machine, which is freely movable *in' both directions in-the line receiving channel of the transporter, so that it does not appreciably resist the movement of the line under the closing action of the movable vise jaw, as in quadding out short matrix lines, but which is positively controlled against overthrowing. The improved line stop therefore is maintained in the desired position of contact with the end matrix of the line and, during subsequent movement of the line away from the vise jaws, the tendency of the end matrices to become dislodged is thereby inhibited.

By constructing and arranging the line stop so that it abuts against the left hand jaw, which is usually the adjustable jaw in the machine, the position into which the line stop is moved each time by the line will be determined automatically according to the setting of this jaw, and by providing the abutments on the front slide bar of the line stop and the front side of the vise jaw with which it cooperates, interference with the rear or casting face of the jaw which closes the front of the mold, is avoided. The mounting of the line stop and its abutment between the front and rear jaws of the transporter conveniently accommodates these parts compactly in the channel thereof in which the matrix lines move.
