TYPE-CASTING MOLD.

SPECIFICATION forming part of Letters Patent No. 405,419, dated June 18, 1889 Application filed September 7, 1888- Scrial No. 284,792. (N0 model.)

To all whom it may concern.-

Be it known that I, HENRY KLEMM, a subject of the Emperor of Germany, residing at arefully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to devices for easting inortised type and freeing them from the mold. The drawings represent the familiar form of mold with my improvements embodied therein.

Figure l is aplan, the up per member of the mold being broken away, showing the lower member in an ordinary position. Fig. 2 is a similar plan showing the parts in the position caused by the opening of the mold, and showing the type just ejected. Fig. 3 is a side elevation of the mold in the same position shown in Fig. 2, but showing the upper member of the mold also and being partly sectional to show the features pertaining to myinvention,

section being made at 3 3 on Fig. 2. Fig. at

is a detail plan of the lower mold with the parts above the bottom plate of the body removed and showing a modified form of the type-ej ecting arm.

A is the base-frame.

A A are brackets to the end of which the arm B, which carries the upper end of the mold, is pivoted in the usual manner.

0 is the back plate of the lower member of the mold.

D is the carriage.

M is the jetrblock pertaining to the lower member of the mold.

N is'the type.

For convenience of reference, the side of the mold on which the jet-block is located will be called the jet side, and the opposite side at which the face of the type is formed will be The body comprises the bottom plate E, the top plate E and the core E gwhich are secured together and to the carriage D in the usual manner. To the rear end of the back plate 0 there is secured the bracket F, on the upper end of which the plate G rests, being kept in position and guided in the motion hereinafter described by the bolt H, which passes down through the slot g in said plate and is screwed into the bracket F.

To the rear edge of the plate G on the under the armI extending in the plane of the lower plate E of the body, said plate being cut away on the face side to allow the finger c' of the arm I to extend through or past it to its for ward edge. The arm J is provided with the finger 7 at the forward end, which extends through the j et-block to the forward edge or face of the same. To the block B, in which the arm B which carries the upper member 13 of the mold is secured, there is pivoted the arm P on the face side. The bolt 19, which forms the pivot, is arranged to bind the arm P quite firmly against the block, so that the arm will not turn readily upon its pivot, but will stand in whatever position it may be placed about the same. The forward end of the arm P, when the said arm is turned on its pivot to the position shown in Fig. 3, abuts against the arm K. To the bed A there is secured the spring L,which stands up in front of the arm K and tends to resist forward movement of the said arm and the parts connected with it, and to retract them after such movement. The arm P is provided with the handle P ,which projects out past the bracket A and is in convenient position to be grasped to swing the arm P out of position for en gaging the arm K.

The operation of this device is as follows: The type having been cast in the usual manner, the core E projecting into and forming the mortise n in the type, when the mold is opened for the purpose of permittin g the type to be discharged, the arm P, standing 1n position to collide with the arm K, engages that arm as the upper member of the mold swings up, the forward end 1) of the arm P moving forward as the upper member of the mold rises, and in that motion sliding the plate G and both of the arms I and J forward. The arm I, by means of its finger 7;, pushes out the type at the face end by its engagement with the edge of the lower wing n of the type below the mortise a, while the arm J by its finger j pushes out the jet end of the type by its engagement behind the jet N. The position of the pivot 19 of the arm P with respect to the pivot b of the upper member of the mold is calculated so that the motion which the mold has in opening is sufficient to move the parts I and J forward a distance as much as the projection of the core E that is to say, the depth of the mortise nso that when the mold is opened fully the type is fully relieved from the core.

Obviously the arm I may be of any width at the end of its finger i, where it impinges on the type to eject it, and it might be constructed, as illustrated in Fig. 4, so that the entire forward edge of the lower plate E of the body should be constituted of the movable part corresponding to the arm I and its finger i, and in that case it would be preferable also to follow the construction shown in said figure by providing two branches I I, joined at the forward end by the portion which constitutes the forward edge of the bot tom plate, one arm passing each side of the screws which bind the parts of the body together, and being fastened to the plate G, one on each side of the bolt H. In case such structure is adopted, the arm J may be dispensed with and the type ejected or relieved from the core solely by means of the part I. In the form illustrated in Figs. 1, 2, and 3 I find it desirable to limit the retraction of the fingers c' and j, so that their ends shall be ,respectively in the plane of the forward edge of the lower plat-e E and the plane of the vertical face of the jet when the type is being cast; and this I accomplish by making the recess e in the lower plate, and providing the finger t with the tooth z" projecting into that recess and having all necessary play longitudinally therein, the recess and tooth, however, being so located that when the rear edge of the tooth z" is stopped against the rear end of the recess e the forward ends of the fingerz' is flush with the forward edge of the plate E, and the end of the finger j is flush with the vertical face of the j et-block.

When it is desired to open the mold by throwing the upper member entirely over, or for any purpose to throw it farther over than it could be opened when the arm P was in position to engage the arm K, said arm 'may be thrown up to the dotted position shown in Fig. 3, when it will not impede the opening of the mold.

I claim 1. In a mold for casting type, in combination with the fixed member of the mold, and a bar reciprocating therein having its forward end constituting part of the type-body-forming face of the mold, an arm actuated by the arm which carries the oscillating member of the mold and actuating said reciprocating bar, substantially as and for the purpose set forth.

2. In a mold for casting :type, in combination with the fixed member of the mold, and a bar reciprocating therein having its forward end constituting part of the type-bodyforming face of the mold, an arm actuated by the arm which carries the oscillating member of the mold and actuating said reciprocating bar, and a spring reacting against the bar to resist its forward thrust, substantially as set forth.

3. In a mold for casting type, in combination with the fixed member of the mold, and a bar reciprocating therein having its forward end constituting part of the type-body-forming face of the mold, an arm connected to the arm which carries the oscillating member of the mold and engaging the reciprocating bar, the connection of said arm to the oscillating member being such as to permit mot-ion of the arm thereat, whereby itmay be moved aside at will to prevent its engagement with the reciprocating bar, substantially as set forth.

4. In a mold for casting mortised type, in combination with the carriage and body secured thereon having a fixed core, and a reciprocating bar underneath the core having its forward end constituting part of the typebody-forming face of the mold, an arm actuated by the arm which carries the upper member of the mold and actuating the reciprocating bar, and a spring reacting against the bar to resist its forward thrust, substantially as and for the purpose set forth.

5. In combination with the carriage and the body having the fixed core, the reciprocating bars I and J, the former lying underneath the core, the latter projecting through the vertical wall of the j et-block, said reciprocating bars being rigidly united at the rear end, and a laterally-projecting arm K, rigid with them both, the arm P, actuated by the arm which carries the upper member of the mold and contacting the arm K, and a spring L, reacting against said arm on the opposite side from the contact of the lever P, substantially as and for the purpose set forth.

In testimony whereof I hereunto set my hand, in the presence of two witnesses, at Chicago this 30th day of August, 1888.

' HENRY KLEMM.
