1'0 (all, w/wm 'II'I nuty concern:

Be it known that I, SYLVESTER J. SENNETT, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Automatic Type-Casting Machines, of which the following is a specification.

My invention relates to automatic typecasting machines.

The object of my invention is to provide a machine of a simple, efficient, and durable construction by means of which type may be not only rapidly and perfectly cast. but also finished by removing the sprue neck or jet and grooving or finishing the sprue or neck end of the type and also nicking the type with one, two, three, or morenicks, as may be desired.

My invention consists in the means I employ to practically accomplish this object or result, as shown in the accompanying drawings, forming a part of this specification.

The machine embodying my invention comprises in cooperative combination a melting pot or vessel for holding the molten typemetal, a discharge nipple or nozzle for the molten metal, a valve-chamber having a valve or choker, a piston-chamber and piston for forcing the molten metal through the valvechamber and nozzle into the mold, a lower or bottom mold member having a smooth upper face and mounted on a reciprocating moldholder to bring the same into close contact with the opposing upper mold members when the same are brought into registry therewith, laterally swinging or movable upper mold members mounted on a laterally-rocking carrier, a reciprocating plunger or blade adapted to slide between and swing laterally with said laterally-swinging mold members and constituting the upper side or face of the mold and serving also by its reciprocating movement to extract or eject the type after it is cast from the upper members of the mold, a matrix and matrix-holder constituting the face end of the mold and adapted to be moved snugly against the end faces of the upper and lower members of the mold, a guide to receive and guide the cast type as they are discharged from the upper members of the mold when the same are moved or swung into registry with said guide, a neck or jet remover or device for breaking off or removing the sprue or neck from the cast type, a knife or grooving-tool for finishing or grooving the neck or sprue end of the type as the type are forced down the guide by said reciprocating plunger 0r ejector-blade, one or more rotating nicking In said drawings, Figure 1 is a plan viewof an automatic type casting and finishing machine embodying my invention. Fig. 2 is a vertical cross-section on line 2 2 of Fig. 1. Fig. 3 is a detail elevation showing the laterally swinging or rocking mold-carrier in its inclined position and other parts in vertical section on line 3 3 of Fig. 1. Fig. at is a detail cross-section on line 4 4 of Fig. 3. Fig. 5 is a detail section on line 5 5 of Fig. 4. Fig. 6 is a vertical section on line 6 6 of Fig. 2. Fig. 7 is a detail front view of the type-nicking mechanism. Fig. 8 is a detail cross-section on line 8 8 of Fig. 6. Fig. 9 is a detail view of a type-holding device hereinafter described. Fig. 10 is a perspective view of the finished type, and Fig. 11 is a partial vertical section on line 11 11 of Fig. 2. Fig. 12 is a section on line 12 12 of Fig. i.

In the drawings, A is the frame of the ma chine, the same being of any suitable form or construction adapted to support the other parts. B is the casting or melting pot for holding the type-metal, and B is the heater for heating the casting-pot.

The casting-pot B is provided with a piston-chamber b, in which reciprocates a piston O, by which the molten type-metal is forced out of the pot into the mold at intervals, as required. The casting-pot B is also provided with a valve-chamber b and a dischargenozzle B preferably projecting horizontally. The valve-chamber I) communicates by a duct or passage 5 with the molten metal in the upper portion of the pot B. This duct or passage is closed at intervals as required by a valve 6 commonly called a choker, engaging the valve-seat 6*. The valve-chamber b also communicates with the piston-chamber 7) by an inclined duct or assa e 72 The valvestem 7) of the valve 5 is also furnished with upper parts or members FF, which form the sides of the mold; a reciprocating plunger or blade G, which reciprocates between the side parts or members F F of the mold and moves or swings laterallywith them and the lower edge of which forms the top face of the mold; a movable or reciprocating matrix H, bearing the letter or character of the type and which forms the end face of the mold, and an end plate E, which is interposed between the mold and the nozzle or nipple B and which has a fine bore or orifice e, registering with the discharge-orifice of the nozzle B and which is provided with a tapering or conical countersink e', which fits and regulateson the tapering or conical end of the nozzle B The two side parts or members F F of the mold are mounted upon a laterally swinging or rocking mold-carrier F, which operates to swing or move the mold members F F and Gr and matrix H first somewhat to one side into position to register with the lower or bottom mold member D of the mold. Then said bottom mold memberD is reciprocated slightly upward to make snug tight close contact with the mold members F F, and then the matrix mold member H is moved or recipro:

cated toward the mold members F F and D to snugly close the end of the mold preparatory to receiving the metal therein. After the molten metal has been forced into the mold by operation of the piston and chokervalve in the pot B the mold member 'D is by its reciprocating movement slightly withdrawn from the .mold members FF, and then i the mold-carrier F swings or moves back laterally to bring the side mold members F F and the reciprocating plunger orblade G into registry with the type-receiving guide K, into which the cast type is discharged by the downward sliding or reciprocating movement of the blade or plunger G, which then takes place. As the type are forced down one after another into the guide K by the plunger G the sprue jet or neck as of the type is broken off the type X by the neck or' jet remover or device M, the same having an inclinedface m, and which is secured to thetype guide K.

N is the finishing or grooving tool for'the jet or sprue end of the type, the same preferably consisting of a stationary grooving tool or knife secured to the type-guide K in position to engage and groove the sprue or jetv end of thetype as the type are forced along the guide one after another by the plunger or ejector-blade G. l

P P are rotary nicking tools or cutters for cutting one or more nicks m in the body-face of the type as the type are forced along the guideK by the plunger or ejector-blade Gr. These nicking-tools are secured on a rotary shaft 39, journaled in suitable bearings j), attached to the guide K, the guide having aslot or opening I; to receive the nicking-tools.

One or more nicking-tools P are secured on the shaft 7), according as one or more nicks 00' are desired in the type.

The required movements may be communicated to the several moving operative parts or devices of my machine by any suitablemotion giving or connecting mechanism, the preferred means for the purpose being illustrated in the drawings.

The piston C is operated or reciprocated as required by means of acam 0' on the main driving-shaft or cam-shaft R, which engages a roller 0 on the bent lever 0, which is pivoted to the frame at c and which'is adjustably connected to thepiston-stem C of the piston (J by a screw-threaded clamp The cam r operates to raise the piston, and it is returned by a quick movement by a spring 0 interposed between the screw-threaded adjustable collar 0* on the piston-stem C and a shoulder C on a bracket C, attached to the frame.

The

valves

6 and 72 or their valve-stem I) is operated or reciprocated as required and in proper time as required by a cam r on the counter-shaft R, which engages a roller 6 .carried on a lever 7), secured to a rock-shaft 6 having an arm I), which engages the valve-' stem 6. The cam r operates to move the valve-ste1n in one direction the direction to seat the valve Z2 on the valve-seat b and it is moved in the opposite direction by a spring 6 connected to the bracket 6 attached to the frame.

The plate E of the mold is supported in position by studs E, connected to the pot B or other stationary portion of the frame.

The bottom or lower part or member D of the mold or its holder D is reciprocated slightly up and down as required to close the same snugly against the side members F Fof the mold by a cam r on the cam-shaft R, which engages a roller {Z on a lever 6Z pivoted at d to the frame and having arms 6Z6 engaging a cross-pin d fitting in a slot (Z in the frame and engaging a spring (Z bearing against the head al of the stem d of the mold-holder D. A further spring d", interposed between the head cZ and a shoulder (Z on the frame, serves to retract'the mold D and holder D. The spring cl", interposed between the cross-pinsal and the stem of the mold, gives a yielding pressure or movement to the mold D against the opposing side molds F F.

The side molds F F are adjustably secured to their laterally movable or swinging carrier F by set-screws f, which pass through slots f in the side molds F, so that the side molds can be set closer together or farther apart, as may be required in casting type of different sizes. In casting type of different sizes or dimensions or thicknesses laterally plungers or extractor-blades Gr of corresponding thicknesses are substituted. The mold-carrier F is moved or rocked laterally as required to bring it into registry'with the guide K and with the bottom mold D by means of a cam r on the cam-shaft R, which engages a roller 7" on the bent lever fiwhich is secured to the rock-shaft f, to which the rocking carrier F is also secured. The lower arm f of the bent lever f"is connected to a spring f, which is attached to the frame and which serves to move the rocking carrier F in the direction opposite to that to which it is moved by the cam r The plunger or extractor-blade Gr is preferably furnished with an integral head g, having a slot 9, and to enable the machine to be quickly and readily set for casting type of different letters, characters of the same font and which require the mold to be of different depths for each different letter and the plunger or extractor-blade Gr to be stopped or held in difierent positions for each particular letter being cast, I provide the machine with a type-set finger or stop G, adjustably secured in position by a set-screw g and adjustingscrew By interposing a type or templet of the desired thickness between the stop or finger G and the plate g of the carrier F the stop or finger G may be quickly adjusted, so that the plunger G will be held in the right position by the stop during the casting operation for casting the particular type desired. The plunger or extractor-blade G is held in its retracted or casting position with the shoulder g of the head g abutting snugly against the type-set stop or finger G by means of springs 9, connected thereto at one end and at the other end to dowel-pins g secured in the carrier F. The plunger or extractorblade G is operated or moved downward to push the cast type out of the side molds F F into the guide K by means of a cam 1 011 the cam-shaft R engaging a roller g on the leverv 9", (see Fig. 3,) pivoted to the frame at 7 and engaging at its outer end a movable rod 9 in the guide and which is provided with an adjustable screw-headed nut that engages a lever g, pivoted to the frame at g and which engages the stem G of the plunger G. The lever g is held under tension by a spring 9 The matrix H or its holder H is given its slight horizontally reciprocating movement asv required at proper intervals to close the matrix snuglyagainst the mold by a cam 2" on the cam-shaft R engaging a roller IL on the arm 72, of the rock-shaft if, the arm it of which engages the stem b" of the matrixholder H. The rock-shaft 72 has a further arm if, connected to a spring 71 for holding the lever or its roller it against the face of the cam r. The rock-shaft k is journaled on the stationary frame of the machine. The matrix-holder stem h is surrounded by a spring b bearing at one end against a collar h on the stem if and at the opposite end against the adjusting-block H on the carrier F and serves to retract the matrix and its holder. The matrix-holder H is adjustably secured in position vertically by an adjustable block H having a threaded stud H and adjusting-nut H, and by the set-screws H".

H" is a guide for the matrix-holder, the same being adjustably secured to the block H by set-screws H The shaft p of the nicking wheels or tools P is rotated continuously by means of a pulley 9' on the driving-shaft R and a belt 11 engaging a pulley p on the nicking-tool shaft 1).

The type-guide K has a yielding back plate K, supported by springs K so that the typeguide K will exert a frictional pressure against the type as they move down the guide. To press or hold the type properly against the sprue or jet finishing tool N, the guide K is furnished with a holding-finger S, pivoted to the guide K at s and held in position to engage the type by a spring S, and thus hold or push the cast type end wise against the spruefinishing tool N as the type is pushed down the guide past said tool.

The matrix H is held in the matrix-holder H and in proper registry with the other parts of the mold by a clamp-pin 725, which enters a registering hole or cavity 71. in the matrix. This clamp-pin is furnished with a collar 71, which bears against the upper side of the matrix. The clamping and registering pin it is mounted in a swinging bracket or arm 71 attached to the matrix-holder H, by a pin or bolt it. A spring It, interposed between the collar It and the swinging arm or bracket lb, presses the pin it" downward against the matrix. and thus holds the m atrix'snu'gly in place in the matrix-holder. A spring 71, (see Fig. 5,) attached to an arm 71 on the swinging arm 78?, serves to hold or push thematrix lengthwise against the end shoulder it of the matrix-holder, thus holding the matrix in position in this direction. pin It is provided with a knob or handle/t to enable this spring-held pin to be readily lifted when changing matrices when casting type of different letters.

The casting-pot B is mounted on a slide or carrier B traveling on guides A on the main frame and furnished with a screw 13* for slid- -ing the casting-pot to and from the mold.

This enables the hot casting-pot to be readily.

The matrix-holding sprue neck or jet &

separated from the mold and other mechanism when the machine is not in operation.

The operation is as follows: The mold-carrier F is first moved to bring the side molds F F and the molds Gr and H into registry with the bottom mold D. The bottom mold D is then moved slightly upward to close the same againstthe side molds F 'F, and the matrix H is moved horizontally to bring the same snugly against the mold members F F and .l). The valve-stem b is then reciprocated to close the valve against its valve-seat 1" and open the discharge-orifice of the nozzle. The piston C is then operated to force the molten typemetal through the valve-chamber and discharge-nozzle into the now closed mold. After a brief pause to allow the metal to set, provided for by the cams, the bottom mold D then moves downward slightly to separate it from the cast type and molds F F, and then the mold-carrier F swings or moves laterally into registry with the type-guide K, when the plunger or extractor-blade G is moved downward and pushes the cast type out of the molds F F into the guide K. As the cast type are forced down the guide one after another by the plunger or extractor-blade G, each successive type operating to push those forward ahead of it, the cast type engages the sprue-remover device N, thus breaking ofi the As the cast type further advances along .the guide K its sprue or jet end engages the neck-finishing tool N, which grooves or finishes the neck end of the type. As the type are further advanced along the guide K by the plunger or extractor-blade Gr they engage the rotating nicking-wheels B, one or more of which are employed, according to the number of nicks m desired in the type. After passing the nicking-wheels and being nicked the finished type are discharged from the machine through the curved lower end (not shown) of the guide K into'the customary receiving-stick.
