SPECIFIGATION forming part of Letters Patent No. 510,288, dated December 5, 1893.

Application filed March 9, 1891.` Serial No. 384,303. (No model.)

To all whom t mag/concern.-

Be it known that I, HERMANN S. POPP, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Type-Casting Mahines, of which the following is a specificaion.

The object of my invention is to construct a type casting machine in which the several 1o parts are simplified and which can be readily adjusted to cast different sized type and to obtain correct alignment, as fully described hereinafter.

In the accompanying drawingsz-Figue 1A, is a side view of a one half of myimproved type casting machine showing the casting parts. Fig. 1B, is a side view of the other half of my improved type casting machine showing the mechanism for rubbing and 2o dressing the type. Fig. 2, is a plan view of the part shown in Fig. 1A, the matrix being moved away from the mold, the cast type being pressed out of the mold. Fig. 3, is a plan view of the portion shown in Fig. 1A, showing z5 the matrix in a position against the mold ready for casting. Fig. 4, is a section on the line 1 2 Fig. 3. Fig. 5, is a sectional plan view on the line 3 4, Fig. 11. Figs. 6 and 7, are detailed views. Figs. 8 and 9, are plan 3o and side views of modifications of the adjusting mechanism of the plunger. Fig. 10, is an elevation, partly in section, of a portion of the machine drawn on an enlarged scale. Fig. 11, is a sectional View on the line 5 6,

l Fig. 5; and Fig. 12, is a sectional view on an enlarged scale on the line 7 8, Fig. 3.

This invention relates to certain improvements in the machine patented by me October 22, 1889, No. 413,550, and in said patent 4o will be found mechanism identical with portions shown in this machine, as, for instance, the vertical sliding side of the mold and the mechanism connected therewith.

Referring in the first instance to Figs. 1A,

1B, A is the frame or table mounted on a suitable base A this table carrying the mechanism for casting, feeding. and rubbing the type.

B is the mold secured to the table A by bolts b, and B is an adjustable screw for 5o steadying the parts thereof and holding them in proper relation to each other. The melting pot C has a nipple c-projectinginto a cavity in an apron or shield c', said cavity being in line with that portion of the mold in which the type is cast. D is a table on which the cast type are pushed one by one by the reciprocation of the ejector plunger G. The side bar E of the mold has a verticalreciproeating movement and is drawn down after the type has been cast, as clearly shown in my patent above referred to, and this side bar has a beveled edge e which strikes against l the inclined face e on the table D when it is forced up into a position for forming one -side of the mold, the side bar being forced against the mold and forming a tight joint therewith. The top of this bar E is flat and acts as a bridge to carry the type from the mold to the table D, as more clearly shown in Fig. l0, which represents a face view of a 7o part of the machine with the front plate removed and the bar E in its lowest position. The barE is reciprocated through the medium of a lever EY pivoted at e2 to a bracket E2 on the base of the machine, one arm of the lever lE being provided with a screw bolt E3, which carries and forms a slide for a ball fitting within a socket in the bar F., while the other arm of the lever carries a roller e3 adapted to be acted upon by a cam F on the cam shaft F, this cam being so shaped as to reciprocate the bar E at the proper time to close and open the mold. Immediately beneath the bar E is an adjusting screw E4, which limits the downward movement of the bar.

The mold B is preferably provided with pipes B3, through which a circulation of water or air is kept up, as illustrated in Fig. 3, and guided in this portion of the'mold is an ejector plunger G, which when in its normal 9o position, forms the side of the mold opposite to that formed by the bar E, but when it is forced forward it ejects the type cast from the mold and transfers it onto the table D, said ejector being suitably grooved to accom- 95 modate itself to the ribs formed in the mold, Fig. 4. This plunger G is attached to a slide G by a binding screw g, which passes through a slotin the plunger and enters a screw threaded orifice inthe carriage. On the under side IOO of the carriage is an arm G2 carrying an adjustable bearing block .g on which 1s a roller.

On the cam shaft F is a cam F2 which acts upon the block gand forces the carriage and plunger forward. A spring Gr3 on a pin G4 returns the carriage to its normal position, but in order to make the return positive I pivot a bell crank lever G5 to the pivot pin e2 and provide the upper arm with a set screw g2 which rests against the arm G2. The other arm of the lever is acted upon by the cam F2. lVhen the cam F2 strikes the lever G5 it forces the carriage back to a position hard against the stop Il. The stop H is in the present instance in the form of a screw threaded in a block H mounted on a plate H2 pivoted at 7L and held in place bya screw bolt h. At one side of the screw II is a slide Il3 adapted to ways in the block II and having a projection which engages with the screw head so that the slide will move with the screw. In this slide H3 is a gage screw h2 between which and an adjustable gage h2 is inserted the gage block to set the gage of the mold, the screw and gage being adjustable to take up for wear. The gage may be made as shown in Figs. S and 9, in which the gage I-I is a plain bar having a head h4 between which and the block ll is placed the gage block of the size of the type to be cast. The clamp screws h5 are used in this instance to hold the gage H in position. The head of the gage is in the form of a set screw so that it can be adjusted when the plunger or the die wears. Pivoted at rf is the matrix lever I carrying at its outer end the head I on which is mounted the matrix as. This lever has a vibrating movement toward and from the mold.

Iivoted to a stud j on the frame A is a lever J. One end of this lever carries a roller j', Fig. 4, adapted to a beveled lug 7'2 on the lever E. The opposite end of the lever J passes up back of the matrix lever I and as the lever E is raised it forces the upper end of the lever J in, which acting upon the matrix lever presses its matrix hard against the mold. I preferably place a spring platej3 on the lever I against which the lever J presses. The lever I is forced from the mold by a spring J inserted between the mold carrier and the lever. rl`he rearward movement of the lever J is limited by a latch plate J2 on the table A, which can be moved to one side when it is necessary to move the matrix lever I ont away from the die when it is necessary to change the matrix or for repairs.

On the table A is a spring plate jt, Fig. 12, which tends to lift the matrix lever as it closes the mold so that it will press up hard against the lip l1 on the mold to make an accurate lit and I prefer to place a lip b2 below the head of the matrix lever I so as to prevent it from dropping, a spring b3 being inserted between the two, aiding the spring jl in keeping the matrix head I' up as shown more clearly in Fig. 11. The matrix head I is swiveled to a post I2 extending' from the lever I and a set screw t" binds the head on the post at any position required. A screw t2 extends into a threaded orifice in the end of the post l2 and rests against a plate or washer A spring i4 is inserted between the Washer and the post so that the head I can be moved along the post and set by the set screw t. The matrix carrier Is is swiveled to the head I by a pin and can be adjusted to any po` sition and set by a screw t, Figs. I and Il. The matrix is clamped to the carrier by a clamp block 7s carried by a screw bolt 7c adapted to an orifice in the carrier, it being secured thereto by a screw 7a2. A nut k2 on the bolt k rests against the carrierso that on turning the nut this clam p block can be drawn tightly against the matrix and hold it Iirmly, as clearly shown in Fig. 5. The matrix is adjusted vertically by a screw 7a4, the head of which presses against the top of the matrix, the spring b3 extending under the lnatrxi carrier I3 tending to lift it. I preferably mount the post I2 on a movable plate I4 pivoted to the lever I by a pin 755, and secure it also by a set screw 7o adapted to a slot in the plate. I prefer to use an adjusting screw la? so `that the operator can accurately adjust the plate. Thus the matrix `carried by the head can be adj usted to the mold universally by the above described devices.

As the type is projected from the mold by the plunger G, it is guided by a plate d at the rear of the table D, so that the `face isalways kept in proper line until the tail of the type is cut oil?. The plate can be on the upper portion as shown in Fig. 6, or onthe lower portion, as shown in Fig. 7. the table D is rounded and the type turns as it is fed from the table D, to the table D. A pivoted arm cl2 presses against the type as they travel around the curve CZ', a spring cl2 pressing against the arm always keeping the arm against the type, but readily yielding when the passage is choked preventing the breaking of parts of the machine. The type is fed from the curve past the rubbingknives L, three in the present instance on each side of the type way, by a plunger M vertically adjustable in a carriage M connected to and operated by a horizontally movable bar M2; the carriage can be thrown out of gear with the bar by moving a clutch pin m, Fig. 1B. The bar M2 is connected at its opposite end to a link M3 pivoted to the fixed portion of the machine at m. The link M3 is acted upon by a cam F3 on the cam shaft F so that the bar and its plunger will have a reciprocating motion. The length of the throw of the cam is sufficient to carry the type past the three rubbing cutters at once, making a cleaner cut type than heretofore.

At the end of the table Dis acurved guide formed of opposite side plates d4 held in piace by springs (Z5, one on either side of the guide and a curved top plate d6 being used in place of the spring arm d2 on the rst slide, if desired. In passing over this slide the type is turned and drops onto a table D2, but the type on this table are preferably fed only the IOO The end d' of i IOS IIO

length of the Ytype past the dressing cutters N. The bar M2 strikes the plungerN when it nears the end of its stroke pushing itforward the necessary distance. The plunger is returned by a spring n.

At the back of the machine is a spring P shown by dotted lines in Fig. 1Bwhich returns the carriage M and bar M2, to their first position ready to be again pushed forward by the cam F?.

The plunger M can be readily raised or lowered according to the thickness of type, by unscrewing 'the set screw m2, lifting the plunger and binding it in itsraised position by the set screw. The set' screwtextends atthe rear of the machine and acts in the present instance, as the bearing for the spring P. At the end of the upper portion of the last guideway is secured a brush Q which serves to clean the type as they pass from the machine.
