20 Claims.

This invention relates to typographical casting machines, such as linotype machines of the general organization represented in United States patent to O. Mergenthaler No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to ap per in print, and then composed in line in an assembler, the composed line transferred from the assembler through an intermediate or delivery channel into a vertically movable transporter or first elevator which presents the line to the face of a slotted mold, the mold filled with molten metal to form a slug against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

In the commercial machines, the matrices are of standard form and dimensions and are commonly provided in their casting edges with two superposed characters ranging in size from 5 pt. to a maximum of 14 pt. The letter characters on the individual matrices are usually alike, the upper one being roman and the lower one italic, and the matrices are composed at one or the other of two different levels to bring either the roman or the italic characters into casting position. After composition, the matrices are maintained at their respective levels by means ofrails which support them by their projecting ears during their circulation through the machine from the time of composition until after the casting operation. In the assembler, the matrices are supported by their lower projecting ears on up- 5 per and lower rails, but in theintermediate channel during the line transfer and when the line is in the first elevator, those matrices standing at the lower level are sustained by their upper projecting ears on a pair of fixed upper rails,while those standing at the upper level are supported by their lower projecting ears on a lower single rail. The lower rail in the first elevator is retractable and, after the casting operation and upon the ascent of the first elevator tothe upper transfer position, the retractable rail is moved forwardly from beneath the matrices standing at the upper level, in order to permit them .to drop to the lower level preparatory .to the transfer of the line onto the second elevator bar. The retractable rail is controlled by cam surfaces formed on a fixed overhead bracket, which constitutes part of the machine framework and just clears the top of the first elevator when the latter has been arrested at its upper transfer level.

In recent years, there has been: an increasing demand for larger faces and, in'attempting to meet-this demand, insofar as two-letter matrices are concerned, many serious'difiiculties have presented themselves. Thus, the distance between the top of the lower character. to the top of the 5 upper character (characters inverted) of a stand} ard two-letter matrix is the same throughout the various fonts and, in order to increase this distance' for characters above 14 pt., without dis- .turbing the location of the upper characterso 10 that the latter character may still register as usual with the mold slot, it is necessary to utilize part of the regular space between the lower pro jecting ear and the top of the lower character. Consequently, when these two-letter matrices 5, are formed with characters above 14 pt., they must be supported in the first elevator at a correspondingly higher level to bring their lower characters into registration with the mold slot. Ordinarily, the space between the lower projecting ear and the routing notch for the lower character is seven-thirty-seconds of an inch, and it has been found that this space may be reduced to three-thirty-seconds of an inch, thereby give ing four-thirty-seconds of an inch additional character space. This means that when such additional character space isfully utilized, the matrices (which will hereafter be referred to as special matrices) will have to be supported in the first elevator at four-thirty-seconds of an inch above the normal upper level.

In order to permit the special matrices to be thus supported,, the present improvements provide, in addition to the customary auxiliary rail, which supports the regular matrices at the upper level, a supplementary auxiliary rail arranged immediately above the auxiliary rail and which supports the special matrices at the upper level in like manner. In the normal position of the parts, this rail stands retracted, so that the regular matrices which have previously been composed in the assembler at the upper level, can be delivered onto the auxiliary rail in the usual way. When it is desired to use the machine with the special matrices, however, and to position these latter at the upper level, the supplementary auxiiiaryj rail is adjusted rearwardly to an active position, whereinit overlies the usual auxiliary rail and, when thus positioned, it will support the special matrices in the transporter at the upper level, with the lower edge of the lower routing notch in register with the datum line of the mold, which is the same for the special matrices as for the regular matrices.

After the casting operation, the transporter is raised to the upper transfer position, wherein the composed line of matrices is transferred to the second elevator for distribution in theusual way. Before the matrices can be transferred to the second elevator however, they must. be

dropped to the lower level, and this is effected in the case of the regular matrices, as previously stated, by retracting the auxiliary rail. As to the special matrices, these are dropped to the lower level by the retraction of. the supplementary auxiliary rail, which is brought about, in the present instance, by the forward movement of the auxiliary rail operating in the usual way.

When it is desired to cast from the lower characters on the special matrices, they are, likejthe regular. matrices, assembled on the upper rail in the assembler andtransferred through the delivery channel on the lower rail provided therein.

In orderthat they may be delivered onto the supplementaryauxiliary rail in the line transporter, however, the lower rail with which the delivery channel is provided is pivotally mounted at its right end adjacent the assembler elevator, so that it may at its left end be adjusted from its normal posit-ion in registry with the auxiliary rail to a higher position in registry with the supplementary auxiliary rail. When thus adjusted, it is plain that the special matrices will be properly delivered to the transporter.

M'eans are provided onthe first elevator for ad- -justing the supplementary aux liary rail to active position when desired and simultaneously therewith to locate the adjustable rail in the line delivery channel in registry with the supplementary auxiliary rail; so 'that'a'c-tually th e operator need concern himself'with but one adjustment;

In one embodiment of the invention, the pivot minim-the line delivery channel registers with the supplementary auxiliary rail in -the'line transporteronly when the latter is in its active position and when the line transporter is at its nor- "rn'al or line receiving. level. In another embodi- As {still another feature, the line transporter is provided with 'a. fixed rail formed with a depend- ;ing tongue adapted to engage in notches formed in the upper faces of the lower-proje'ctingears of the special matrices when the latterare assembled .at'the upp'er level, in order to prevent such matrices from being displaced from the transporter duringthe receding action of the mold after the casting operation.

The special matrices K (see Fig. 11) are similar to the regular matrices in most respects, that is, they 'are of standard form and dimensions and provided"with 'an upper pair of projecting ears X and ?aflo'wer pair of projecting ears X In their oasting edges, the matrices X are'formed -with t'wo superposed characters X and X but these-special matrices differ from the regular matri'ces in that"the characters range in siZe throughout the various matrix fonts from 14 pt. up to; say, 18 ptpinst'ead of from 5 pt. to l4 pt., as in the case "of the regular matrices. In addition,

pose to be hereinafter described. In the normal operation of the machine, th

- composed line of matrices is transferred, as usual,

to the'vertically movable first elevator or trans- I supported by the auxiliary rail, if they be the special matrices (Fig. '3). Upon receipt of the "their upper surfaces with notches X for a pur- 1 -a, and those composed at the upper level will v be supported by their lowerprojecting ears on b an auxiliary-retractable rail B (Fig. 2), if they be the regular matrices, or -on a supplementary auxiliary rail B located immediately above and line, the first elevator descends until it banks upon a vise frame C, and in this way positions the line in front of a mold D between a pair of line clamping jaws (not shown) which are slidably mounted in guideways formed in the vise frame.

The mold (Fig. 3) comprises as usual a body portion D a cap portion D and a pair of intermediate liners (not shown), the cap and body portions forming the upper and lower side walls of the mold slot, and the two liners the end walls thereof. The body portion of the mold also presents a pair of upper and lowerfalining ribs d and d respectively, which are positioned directly over and in engaging relation with the lower projecting ears of the matrices when the mold carrier is advanced to force the mold against the matrix line for the casting of the slug. In this connection, it may be mentioned that, due to the higher level at which the special matrices must be supported in the first elevator to bring their lower characters into. casting position, the upper alining rib d on the mold (which is intended only for the special matrices) is made proportionately thinner than the corresponding rib on the regular mold used for the regular matrices.

After the casting operation and the mold D recedes, the first elevator A is raised to the upper transfer position (Fig. 4) where the matrices are caused to assume a common level and the line is then shifted horizontally by a transfer slide onto the second elevator bar (likewise not shown) which carries the line upwardly to the distributing mechanism.

As best shown in Figs. 1 and 2, the first elevator A includes a long vertical body portion, which is slidably mounted in the vise frame C, and the improved head portion which comprises as usual, front and rear side walls A and A and the intermediate connecting block A (Figs. 2 and 3) arranged at one end of the elevator head. One of the fixed rails a is formed integral with the rear side wall A while the other is presented at the upper edge of a bar A extending longitudinally of the head portion and screwed to the front side wall A of the elevator head. The bar A in its lower edge is recessed as at a and the upper face of the recess presents a depending tongue or lip a that extends into the notches X formed in the lower ears of the special matrices when the latter are assembled at the upper level (see Fig. 3). The engagement of the tongue 11 in the notches of the matrices prevents the latter from being displaced from their proper positions in the elevator head upon the recession of the mold after a casting opera-' tion.

When the regular matrices (see Fig. 2) are assembled at the upper level, they are supported on the auxiliary retractable rail B supported on a ledge A positioned beneath the front wall A of the head portion and held in spaced relation therewith by depending portions A formed on said front wall (see Fig. '7). The auxiliary rail B is recessed at its opposite ends as at b, in order to cooperate with a pair of small levers A pivotally mounted adjacent their centers in the front wall A of the head portion. These levers at their lower ends are formed with nose portions a that engage in the recesses 22 just alluded to, and are urged in a direction (counterclockwise) to maintain the auxiliary rail in its active position by a. pair of springs A arranged one at each side of the first elevator and having an anchorage at their front ends in said elevator. The springs are connected at their rear extremities-in eyes a with which the levers A are respectively provided. As just stated, the auxiliary rail B is normally held in its active position and, when the regular matrices are supported at the lower level by the engagement of their upper ears with the fixed rails a, the lower ears of said matrices stand beneath the auxiliary rail, whereas, when the regular matrices are at the upper level, they are supported on the auxiliary rail by the engagement of their front lower ears on that portion of the auxiliary rail that projects beyond the rear face of the front side wall'A (see Fig. 2).

Before the regular matrices, which are supported at the upper level, can be transferred to the second elevator fordistribution, they must, as previously stated, be dropped to the lower level in the transporter, and this is brought about by the retraction of the auxiliary rail B, which is effected when the transporter arrives at its upper transfer level. For this purpose, the levers A are formed at their upper ends with cam surf-aces a that engage bearing pieces E fixed in the bracket E that overlies the first elevator and which constitutes part of the machine frame. As

. the levers engage the members E, they are cammed in a direction (clockwise) to retract the auxiliary rail B against the tension of the springs A whereupon the matrices will drop to the lower level as shown in Fig. 4. As the line transporter A descends to its normal position, the levers A are released by the bearing pieces E, Whereupon the spring-actuated auxiliary rail is allowed to return to its normal active position.

The supplementary auxiliary rail B which supports the special matrices at the upper level, is formed in its bottom surface witha recess B that fits over a raised portion B of the auxiliary rail, but the recess 13 is somewhat wider than said raised portion so as to allow for a certain amount of relative movement between the two rails for a purpose hereinafter set forth. Unlike the auxiliary rail, the supplementary auxiliary rail is normally maintained in a forward or retracted position (Fig. 2) in order to stand out of the way of the regular matrices when the latter are supported at the upper level on the auxiliary rail, but when the special matrices are used, the supplementary auxiliary rail is moved rearwardly to the position shown in Fig. 3, whereina supporting ledge is presented for the support of the special matrices at the upper level by means of their lower projecting ears X The difference in width between the recess B in the bottom of the supplementary auxiliary rail and the raised portion B of the auxiliary rail is such that the supplementary auxiliary rail can be adjusted from its inactive to its active position without altering the position of the auxiliary rail.

The supplementary auxiliary rail B is adjusted from itsinactive to its active position by a pair of slide members F and F arranged at the top of the first elevator A and which are settable as a unit. The upper slide member F (see Figs. 3, 5 and 6) is tongued and grooved into a pair of spaced parallel retaining members G and G screwed to the first elevator at the top and is formed in its bottom face and near the front with a recess F into which there projects a raised portion F formed on the bottom slide. The slides are each formed at their forward ends with upwardly projecting fingers F and F one fitting within the other, so as to facilitate the adjustment of the slides as a unit. The normal'pos'ition of the slides, i. e., the position corresponding to the retracted position of the supplementary auxiliary rail 13, is illustrated in Figs. 2 and 5, and this is determined by thebanking of a lug F formed on the top slide against an adjustable stop G 'formed in a cross piece G screwed to the slide retaining members G and G The rearward position of the slides, i. e., the position corresponding to the rearward or active position of thesupplementary auxiliary rail, is determined by the banking of the lug F against a second adjustable stop G likewise threaded into a cross member G similar to the cross member G but spaced somewhat to the rear thereof. The lower slide F is held in either of its positions of adjustment by a spring-pressed detent G fthat engages in one or another of a pair of recesses g and g formed in the bottomsurface of said lower slide, the detent being housed in a hole drilled in the first elevator for the purpose. Not only does thedetent G hold the lower slide F in its different positions of adjustment, but actually it also holds the upper slide F, when both slides are in the forward or normal position, it being noted that under such conditions, the recess g in the lower slide registers with a recess 9/ in the upper slide, and as the recess g is large and extends through the lower slide, the detent;

- G: will be enabled to cooperate with the recess 9 to hold the upper slide in place. In order further 'to' insure the simultaneous adjustment of, the slides F and E, the slide F is equipped with a pin f, having a head portion ,f projecting into an enlongated slot Rand which will engage the bottom slide F at the rear end of the slot to move it rearwardly along with the top slide, in the event the operator grasps only the latter in making the adjustment. 7

When the slides F and F are adjusted from the position shown in Fig. 2'to that shown in Fig. 3, the setting of the supplementary auxiliary rail 13' to active position will be effected through mechanism which includes a pair of rocker arms H pinned at the opposite ends of a rock shaft. H

.journalled in the overhanging portion of the elevator A and which are formed at their upper ends with bifurcated portions H that straddle the flattened ends of a transverse-rod H journalled at its center in a bearing formed at the rear end of the top slide F. ;The rocker armsH "are connected at their lower ends by means of socket joints to the forward ends of a pair of connecting rods H which in turn are connected at their rear ends by similar joints to a pair of levers I-I arranged adjacent to and pivotally mounted on the same pivot rods as the levers A' which effect the retraction'of the regular auxiliary rail 3..

' iary rail B and it may be noted here that the supplementary auxiliary rail is slotted in the vicinity of the levers A in order that the latter may pass through the rail and cooperate with the regular auxiliary rail in the manner hereinbefore set forth. 7

According to the'foregoing arrangement, the adjustment of the slides F and F rearwardly (see Fig. 3) will ellect a forward movement of the links H which in turnwill actuate the levers H in a direction (counterclockwise) to move the supplementary auxiliary rail B rearwardly or into its active position, wherein it will support the special matrices X at the upper level.

As in the case of the regular matrices, the

., delivery channel 'J matrices are composed at the lower level, they will means which effect the retraction of the regular auxiliary rail. As a matter of fact, when the supplementary auxiliary rail is in its active position (see Fig. 3), the raised portion 13 of th'e auxiliary rail banks against the front face of the recess B in the bottom of the supplementary auxiliary rail, so that,.as the' levers A are cammed' rearwardly upon the arrival of the line transporter at its upper transfer level, the supple-v mentary rail B will be moved forwardly or retracted along with the regular auxiliary rail B. The retraction of the supplementary rail turns the levers H in a clockwisedirection against the force exerted by compression springs H associated one with each of said levers, and which seat in recesses formed in the front elevator wall A and bank against lateral extensions H formed at the upperends of the levers H This movement of the levers H is permitted by reason of the fact that the top slide F, under such conditions, V

is allowed to move forwardly with respect to the bottom slide F (see Fig. 4), the slot being long enough to permit this. movement. descent of the elevator A from its upper line transfer position, the springs 1-1 will act upon the levers H to turn them in a counterclockwise direction again to locate the supplementary auxiliary slide B in its active position to receive the next located in normal position. The force exerted by V the springs H is not suflicient to overcome the restraining elfect of the detent.

The matrices are assembled in line in an as- 5 sembler elevator I, where they are composed on one or another of a pair of rails, depending upon whether they are to be transferred to the line transporter A at the upper or lower level. From' the assembler elevator, they pass through the line and here again, if the be supported in the delivery channel on fixed rails J (Figs; 7 and 8) by their upper ears,

whereas if they are composed at the upper level, they are supported by their lower ears on a grooved rail J with which the delivery channel is provided. This is true both forthe; special matrices, as well as for the regular matrices. In

accordance with the present invention however, this grooved rail J is pivotally mounted at its right end (the entrance end of the delivery channel) on a pin J mounted in the delivery channel and adjustably secured in place by a pair of nuts J? threaded on said pin at its outer end (see Fig. 5). According to the arrangement, the rail J may be adjusted so as to locate its left end, i. e., where the matrices pass from the delivery channel to the line transporter, into register either with the auxiliary rail B or the supple- Upon the ao'odooo mentary auxiliary rail B so that, depending upon whether the regular or special matrices are in use, they will be transferred to the auxiliary rail or the supplementary auxiliary rail, respectively.

The movable rail J 2 being grooved, the lower wall of the groove will present a bearing surface for the matrices as they pass through the delivery channel, the upper Wall acting merely as a guide to insure the proper entryof the matrices into the line transporter. V

The pivoted rail .1 is supportedat its left end (see Figs. '7, 8, 9, and 10) by an angular shaped lever J the vertical arm of which is pivotally secured at its upper end to a fixed portion of the delivery channel as at J and the horizontal arm of which is connected. to the rail by a pin and slot connection J When the angular shaped lever J hangs freely, the rail J under the influence of gravity, will assume a horizontal position (Fig. 8) in register with the auxiliary rail B in the line transporter. However, when the angular shaped lever J is swung to the right (see Fig. 7) ,the rail J will be swung upwardly and located in a position in register with the supplementary auxiliary rail B (Fig. 7)

The swinging of the lever J and consequently the pivotal movementof the rail J is effected automatically, and for this purpose the lever J is formed on its left edge with a protrusion J adapted to cooperate with the supplementary auxiliary rail B When the latter rail is in its retracted position (Fig. 9), a recess b formed in the right end thereof will be in alinement with the protrusion J on the lever J and the depth of this recess is such that the lever is free to assume its normal position wherein the rail J will register with the auxiliary rail B. However, when the supplementary auxiliary rail B is adjusted to its active position in the manner hereinbefore set forth, a bevelled portion 1) on the rail B located at the front end of said recess b will cooperate with the protrusion J on the lever (Fig. 10), camming the latter to the right, and consequently effecting the upward movement of the rail J to bring it into register with the supplementary auxiliary rail B The protrusion J 3 is formed with inclined upper and lower faces, as well as rounded-off frontand rear faces, the upper and lower inclined faces allowing the first elevator A to move between its upper transfer and its lower casting levels without interference when the supplementary auxiliary rail is in its active position, and the front and rear rounded-off faces permitting the vise frame (which, as is well known is pivotally mounted) to be swung downwardly and returned to normal position. To facilitate this movement of the vise frame, the supplementary rail B is provided at its right end and in its rear edge with a shoe b bevelled in its front and rear faces, the front face acting to cam the lever J out of the way when the vise frame is swung downwardly, and the rear bevelled face acting upon the lever in like manner when the vise frame is restored to normal position.

At the entrance end of the first elevator jaw, there is provided, as usual, a small spring pawl K (Fig. 8) that is sprung outwardly by the incoming line of matrices to allow the line to pass through and which springs back again into position after the line has entered the transporter, to prevent the last matrices from falling out during the movements of the first elevator. In the improved machine, an additional spring pawl K is provided, located just above the regular pawl K and which cooperates with the special matrices X in like manner when they are positioned at the upper level.

It will be understood, of course, that a composed line may consist of special matrices assembled at the upper level, as well as special matrices assembled at the lower level, just as in the case of the regular matrices.

In Figs. 12 to 18, there is illustrated another embodiment of the invention, wherein the rail J in the intermediate delivery channel is maintained in its set position, irrespective of the position of the first elevator. The devices for adjusting the supplementary auxiliary rail B fromac tive to inactive position in this embodiment are the same in all respects as those in the embodiment hereinbefore described. .The difference lies in the mechanism for adjusting the pivoted rail J 7 According to this embodiment of the invention, the rail J is adjusted from its lower position (Figs. 12, 13 and 16), wherein it registers with the auxiliary rail B into its upper position, where-, in it registers with the supplementary auxiliary rail B (Figs. 14:, 15 and 17) throughthe medium of a bell crank lever L which includes a vertical arm L pinned at the outer end of a short stub shaft L journalled in the front wall of the delivery channel and a horizontal arm L fixed at the rear end of said shaft and which is mounted in a recess J with which said front wall is equipped.

The horizontal arm L is formed at its left end with a bifurcated portion Zthat straddles a pin J provided on rail J the arrangement being such that, as the bell crank lever L is moved in a clockwise direction, it will adjust the rail J from its lower position shown in Fig. 16, to its upper position shown in Fig. 17; whereas, when it is moved in the opposite direction, the reverse positioning of the rail takes place. The bell crank lever L is moved into its different positions of adjustment by a horizontal slide M tongued and grooved in the front Wall of the delivery channel and which is formed with an elongated slot M into which there projects a pin L provided at the upper end of the vertical arm L of said bell crank lever. When the slide M is moved from its normal position (Fig. 12) to the right (Fig. 14), it will through the medium of a spring M fastened to the bell crank lever L and anchored in said slide,

swing the bell crank lever to the right until it is arrested by the banking of the pivoted rail J against an overlying stop J fixed in the delivery channel front wall, in which position of the parts the rail will register with the sup-plementary auxiliary rail B As the slide M is thus adjusted to the right, it releases a spring-pressed detent M housed in the delivery channel wall, allowing it to move forwardly into the path of a boss L formed on the rear face of the lever arm L thus holding the lever L against turning to the left and disturbing the setting of the rail J Normally, the detent M is held in its retracted position out of the path of the boss L by the slide M, the rear face of which engages a pin m rising. from the detent at the top, but when the slide is moved to the right, a recess m formed therein is brought into register with the pin, thus allowing a limited forward movement of the detent M for the purpose just mentioned.

When the bell crank lever L is brought to rest by the banking of the rail J 2 against the stop J there is an overthrow movement of the slideM, which is allowed by virtue of the slotted conneccrank lever.

tion M between the slide and lever, and this overs throw or excess movement is utilized during the return movement of the slide to the left to effect the retraction of the detent M to release the bell As shown in Fig. 14, the'recess m which receives the pin m on the detent is formed with a wedge surface, so that, as the slide M is moved toward the left, the pin will be forced inwardly and thus effect the retraction 'of the detent. Thereafter, the slide at the right end'of the slot M will contact with the pin L in the bell crank lever and its further movement will rotate the bell crank L tothe left, thereby returning the rail J to its, lower ornormal position, which position incidentally is determined by an underlying stop J similar to the stop J At this point, it may be stated that both of the stops J and J as well as the boss L on the bell crank lever, are in the form of eccentrics to give a limited range of adjustment so as accurately to locate the parts. It might also be mentioned that the slide M is held in its different positions of adjustment by a spring pressed detent m which engages in one or another of a pair of recesses m (see Figs. 12 and'l4) formed in the rear face of the slide.

' The adjustment of the slideM is effected automatically with the setting of the supplementary auxiliary rail B and the mechanism for this purpose includes a slide member N carried by the first elevator head. The. member N includes a shoe portion N at the right tongued and grooved into the first elevator jaw (Figs.,12, Band 18) which cooperates with a headed pin N fixed in and formed in its rear edge with two spaced recesses N and N one of which N (that at the right) normally receives a forwardly projecting finger m with which the slide M is provided, an

intermediate portion N connected to the shoe N and a'plate N connected to the intermediate portion N and .provided with anundercut slot N the elevator headat the bottom, the pin and slot connection serving" to guide the member N in its adjusting movements. The slide member N is adjusted from the top adjusting slide F, and for this purpose it is'connected Withsaid slide by a horizontal arm N formed at its opposite ends withbifurcated portions n and n one of which end portions n straddles a pin n projecting downwardly from the slide F at its rear end, and the other of which end portions n engages the flattened sides of a reduced portion n at the upper end of a vertical shaft N journalled in the elevator head. At the lower end of the shaft N ,'there is pinned a fore-and-aft arm N which is connected at its rear end to the plate N According to the foregoing arrangement, the slide F will,'when it is movedrearwardly to effect the adjustment of the supplementary auxiliary rail B to active position, rotate the shaft N in,

N to the right to effect the raising of the rail J in the line delivery channel, all in the manner previ-, ously described. .This adjustment, of course, must be effected when the first elevator is-in the line receiving position, since only at this time-is there any active cooperation between the slide M in the delivery channel and its actuating slide N in the first elevator. The adjustment of the rail J is maintained until it is again adjusted to normal position by the outward manual adjustment of the slide F to effect the retraction of the supplementary slide B 'Here again, the adjustment can only take place when the first elevator is in .its line receiving position. It will be noted that; the connection between the slides M and N is such that their cooperating portions can freely pass each other during the movement of the first elevator, without interference. Should the adjusting slide F be moved inwardly when the first elevator is in a. position other than the line receiving posi-- tion, or, say, when the vise frame is open, and the adjustment not corrected before the elevator is returned to its line receiving position, or the vise frame closed, the operation of the machine will not cause breakage of theparts, since, under such conditions, the second recess N at the leftin the inpreferred form, and obviously, many variations.

and modifications may be made therein which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not limited to any specific form or embodiment, ex-. cept insofar as such limitations are specified in the appendedclaims.
