MOLD-ACTUATING- MECHANISM FOR TYPE-MACHINES.

To all whom it may concern:

Be it known that I, FRANK Trimaran PIER- i'ox'r, a citizen of the United States, temporarily residing at Horley, county of Surrey, llngland. have invented a certain new and useful Improvement in Mold-Actuating fvlcchanism for Type-Machines; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to that class of type casting machines wherein the mold is equipped with a divided mold-blade the sections whereof are independently movable for the production of low body type, and it has for its objectto improve the mold and simplify and render more certain the actuating mechanism controlling the relative 1 positions or adjustments of the mold-blade l sections, as hereinafter described, the novel features being pointed out in the claims. i

In the accompanying drawings illustratl ing a preferred form of embodiment, Figi ure 1 is a side elevation of a portion of a i type casting machine with the improvedi actuating mechanism applied thereto, a pori tion of the latter being in section on the line 1-1, of Fig. 4. Fig. 2 is atop plan view l and Fig. 8 is a right hand side elevation of the devices, Fig. 1. Fig. st is a top plan l view, partly in section, showing the mold l equipment. Fig. 5 is an enlarged sectional l view of the hold taken on line 2-2, of Fig. 1. Fig. 6 is a perspective view of the l mold-blade sections detached and separated. 1

Like letters of reference in the several figures indicate the same parts.

As illustrated, the improvements althougl equally applicable to other forms, are spe cially designed for use in connection with the type casting machine of Patent No. i 625,998, dated May 30, 1899, whereof X is i a portion of the bridge supporting the ceni tering pin (not shown) and die-case O. l The type mold is preferably like that of 1 Patent No. 752,81 l, dated Feb. 23, 190A, of i which A represents the frame or base plate, A the side blocks, and A the cross-block, and the divided mold-blade with which it is equipped is similar to that of a companion i application, Serial No. 397,409, filed Octo- 1 ber 14, 1907, of which B is the body or main l Specification of Letters Patent.

section and C the overlying r cut-off section provided with a web or plate a extending along one side of the body section within Instead, however, of providing the main section B with a rear extension for the cross-pin, and the cut-off section C with a vertical extension for the attachment of its actuating mechanism, both sections are formed of the same length over all so that when their rear ends are in the same vertical plane their front or casting faces will be in alinement. The main blade B is also furnished in its rear portion with an opening B in which is fitted a shouldered portion B of an actuating block or head B the latter riding in a seat formed in a fixed member E and provided with a rear extension B preferably in alinement with the mold-blade channel, for the reception of the actuating and adjusting mechanism of the casting machine proper. As illustrated said extension B is provided with an orifice B for the reception of the usual cross pin. The cut-off section G is in like manner provided with an opening 0 in which is fitted the shouldered portion of a block C hen the sections B, C, are assembled with blocks B and C in position, as indicated in Figs. 4 and 5, said blocks are held from lateral displacement by the engagement of their outer faces with the walls of a groove or channel formed in member E afliXed to or formed integral with the rear flange of base plate A, which flange is also preferably cut away as shown for the accommodation of head B Block C with its shouldered portion fitted to and filling the opening C in cut-off section C is formed with a transverse orifice provided with opposite beveled surfaces C C for the reception of the correspond ingly beveled surfaces of oppositely disposed bolts D D arranged to reciprocate longitudinally in a direction transverse to the mold-blade sections.

Bolt 13* is mounted in bearings in fixed member E and when advanced to enter the orifice in block C its beveled end engages the beveled surface 0 and operates by its wedging action to advance the cut-off section O against cross-block A thereby closing the end of the mold-cavity when a short body type is desired. Bolt D is mounted upon and takes its bearing in block B and enters the orifice in block C on the opposite side from bolt D and 'it engages beveled surface C in a manner to retract the cut-oil section C and seat its rear end against the gaging surface B of head B thus holding the two mold-blade sections with their casting faces in alineinent, which is the position they assume when full body or character type are desired. The projection and seating of bolt D while restraining movement of the cut-off section C, does not interfere with the movement of the body section B, which latter is free to respond to the regular adjusting devices applied to head B and. the withdrawal of bolt D and engagement of bolt D with block C has the effect of locking both mold-blade sections upon the head B for simultaneous adjustment, said head B providing an ample bearing for bolt D as well as a shoulder or gage B for alining the casting faces of the two sections. The front stop for the mold-blade sections is with a hardened block E detachably applied to the rear flange of bed plate A in position to be engaged by block C when the mold blade sections or either of them are advanced into contact with the face of cross-block A thus permitting shorter mold-blade sections to be employed and avoiding the presence of the usual front stop opening.

It is the intention that bolts D D should alternately engage block 0-, to which end they are connected to a member D supported to reciprocate transversely of the mold-blade sections in bearings formed between fixed member E and base plate A. This member D is furnished with upwardly extending cheek pieces D D on opposite sides of blocks 13 and CE. The cheek piece D is provided with a socket for the reception of the threaded end of bolt D while cheek piece D is provided with a groove D in which is received a flange or collar D on bolt D The groove D is in parallel with the mold-blade channel, to permit independent lateral movement of bolt D the latter being supported in and moving with block B seated in the body section B.

A spring F is applied to member D in a manner to normally project bolt D into engagement with its seat in block C and at the same time retract bolt D' thereby causing bolt sections B, C, to be locked upon head B This is the position for casting full body or character type. \Vhen short body type or quads are desired, it is only necessary that member D shall be advanced against the tension of its spring F, to withdraw bolt D and engage bolt D advancing responds to the dimension adjusting devices.

The actuating mechanism for automatic ally advancing member D whenever a low quad or space is called for includes as its thereby and locking cut off section C and releasing body section. B so that it alone principal, elements a motor device arranged to act upon. said member D in opposition to or suspending the action of said. motor device; tripping devices for said restraining or suspending means operating to release or energize the motor device and means for returning or restoring the energy of said 1notor device.

In the preferred form of embodiment illustrated the motor device is represented by a plunger G supported in guides on a bracket R the latter detachably secured to the bridge X or other suitable part of the casing machine frame; a motor spring H interposed between the bracket and an adjustable head G and a lever K pivoted at K and having one arm in position to engage a projecting portion D of member D and the other arm coupled by a link K to plunger G. The arrangement is such that the superior tension of motor spring H, if uin'estrained, will overcome retracting spring F and shift member D in a direction to en gage bolt D and disengage bolt l The restraining or suspending means for the motor device is represented by a latch J pivoted at J to the bracket P in position to engage a shoulder J on plunger G, and thereby prevent movement of said plunger in a direction to actuate member D, said latch J being advanced by suitable means to engage shoulder J as by a spring L interposed between the bracket and a shoulder on red L, the latter pivotally connected to said latch. The tripping device for rendering the motor active is represented by a shaft I? mounted in bearings on bracket P and provided with an arm M coupled to rod L, and one or more arms N in position to be engaged by die case O when tl e latter is brought to the position or positions assigned to low quads or spaces. The motor restoring means is represented by a lever P pivoted at P on the bracket with one arm I in position to engage plunger G in a direc tion to compress its motor spring and restore latch J, the other arm of said lever eXtending above and in position to be engaged by a moving part of the casting machine, such as the centering pin lever B.

The operation is as follows :As is well i known the matrix carrier or die-case O is {movable in two directions in a horizontal plane to bring its various matrices succes- J sively into position opposite the mold, and l l when moved into position to cast spaces it contacts with one of the arms l thereby rocking shaft N in the direction indicated by the arrow in Fig. 3. The effect of this is to I withdraw latch J from shoulder J thereby releasing plunger G which is immediately I driven upward by spring H and causes the advance of member D against the pressure l of its retracting spring F. Bolt D is thereits retracting spring; means for restraining I by withdrawn from and bolt D into engagement with block C whereby the cut-off section C is advanced to close the mold. This advance of the cut-off section C takes place during the first part of the descent of centering pin lever B while the adjusting devices are operating to position the body section B, and is completed before the selected matrix is seated upon the mold. The cast having been made, upon the rise of lever R, incident to the withdrawal of the matrix from the mold, lever P is engaged to return plunger G into position to reengage latch J, thereby not only restoring the power of motor spring H but positively withdrawing connecting lever K so that member D, responding to its spring, is automatically shifted back to normal position, with the two mold-blade sections locked in position on head B If the next succeeding type called for is a full body or character type the shifting of the die case incident to the selection of the matrix permits latch J to engage shoulder J so that upon the next descent of lever It the action of motor spring it will be suspended, and the two moldblade sections being locked to block B with their casting faces in alinement will be moved in unison by the adjusting devices connected to said block.
