Y rYroGnA'rnIcAL oAs'rmo MACHINE-- Application filed- August 31 Be it known that I, SUNKER ABAJ BIsEY,

I I a subject of the King ofGreat Britain, and v machine, Figs.

a resident of New ork city, county and State of New York, have invented certain new and useful Improvements in Typographical Casting Machines, of which the following is a specification. a

My present invention is a machine-for casting leads, rules or slugs of typogra'phi-. cal matter and differs from machines ofthe-- prior artprincipally in that the leads, rules 'or otherm'atter are produ-ced inv fini shed form or a continuous, asdistinguished from an intermittent casting operation. This means greater speed and uniformity of product, as well as many other advantages which will appear as the specification proceeds.

In the accompanying drawings illustrating various embodiments of the invention,

Fig. l is a broken side elevation of the with the .mold shown in section. 2 and 3 are end views of the mold with the cast product issuing from the mold shown in section. I g

Figs. 4 and 5 are sectional views of screw and, gear types of pumps for thermetal. Fig. '6 is a part sectional end view of the machine. v r 3 Fig. 7 is a part sectional plan view.

I Fig. 8 is a cross sectional view on sub stantially the plane of line 8-8 of Fig. 7.

Figs. '9 and 10 are plan views of forms of 1 continuous mold sides.

The mold, as best shown inFig 1, con sists of upper and lower relatively adjustable mold blocks 11 and 12, .and aninner side wall member 13 having a back' or rear wall. 14 provided with a nozzle passage 15 for flowing the molten metal into the-space thus defined (Fig.

The outer 51 e of 'thismold channelimay be closed by a relativelyfixed wall such as I have shown at 16 in Fig. 2. For casting leads this side wall member will have an angular extension .17 projecting in between the top and bottom blocks 11 and 12,150 reduce the width of the cast product, which latter is indicated at 18. This outer side wall member may be removable and adjustably' held in place as by, means of secur ing screws 19 engaged in seats provided therefor in the bottom mold block.

The upper mold block is' shown as ad; justcd to vary the thickness of the casting by means of a nut 20 (Fig. 1) engagedon a v the over the nozzle.

"screw stem fast to the upper mold block;

said nut being rotatably held between the top of the framing 22in which this upper block slides and a bridgeor abutment 23. With this construction it will befseen that upon turning the nut 20 the upper mold block will be shifted-vertically toward and away from the lower relatively-fixed lower block soas to vary channel.

, The upper and lower blocks are shown as provided at their ex'it' ends with tapered extensions24 and 25 forming lips for guiding the solidified product to the .drawing out mechanism. .This drawing out mechanism consists in the present disclosure of upper and lower the height of the mold sets of conveyor" chains 26 and 27 carried by sprockets 28,- -28 and .29, 29. These upper and lower sets of chains are connected to travel in unison as b'y'connecting their supporting shafts 30,. 31: atone end with suitable gearing 32. v

The cast product is gripped between the cross bars or plates 33 of the lower conveyor and the universally adjustable spring pressed cups 34 Qf the upper conveyor. The

cross bars of the lower chains are shown ';.S guided and supported during the active period of theiroperation by having their ends engaged in suitable uides of the supporting framing (Fig.6 and are further shown as recessed at 36 to take the head of typographicalmatter cast with an overhang.-

In casting type bars or other matter with an overhang such as shown at 37 in Fig. 3 the outer side of the mold channel is'closed by a-plate 3 8 grooved or channeled at, 39'

to provirde the chamber 'ang.

This mold side is a guidejO so that it may slide along with for the metal of shown as supported in the'casting.- This sliding feature is further a series of threepistons 45 operating in cylinders 46, said pistons being connected at their upper ends at 47 with links 48 pivoted' at 49, said being reciprocated from connecting rods connected by the cams the mold chamber filled during the operation of the machine. The pump pistons are shown equipped with inlets 52 and with I check valves 53 as is common in this art and in addition there are shown check valves 54 to prevent the operation-of one pump exerting back pressure or suction on the other pumps. 1 I Other forms of continuous feed pump mechanism may be employed such as the screw type of pump shown at 55 in Fig. 4 or the gear type of pump illustrated at 56 in Fig.5, the main requirement bein" that the pum) mechanism shall be of sue a nature as to keep the mold chamber continuously filled with metal while the casting is solidifying and ward end of the chamber.

The flow to" the mold chamber is controlled in the illustration by a gate valve 57 (Fig. 1) sliding in front of the supply nozzle and having a port 58 for registry there: with. This gate is shown as operated by 21 pivoted lever 59. When the gate is brought down to shut off the flow of metal, the

'sprue in the port 58 is automatically knocked out by a tappet 60 carried by the bell crank 61 and operated by a slide 62 engaged at its upper end at 63 by the gate handle 59, toward the end of its downward movement. The parts areso timed that'the tappet will not be operated until the port has been brought down into registry with the tappet, in which event the ejected metal I will fall through a discharge opening 64.

In Fig. 9 I have illustrated an endless chain 65 carrying matrix side sections 66, matching end to end to form a continuously moving closure for the open outer side of the. mold. These mold sections are held pressed"- against the side of the lnold by rollers 67 traversing a guide 68.

' In Fig-i101 have shown how a continuous band 69 may be employed as a movable matrix wall, said band bemg held up to a mold closing position by supporting rollers Y The cast product as it is withdrawn from the mold maybe automatic-ally cut in predetermined lengths by a knife 71 slidably mounted in guides 72 on the upper chains and adapted to cooperate with guides 73 on the lower chains.

This knife is normally retracted by a spring 74 and is forced down into the cutting position shown in Fig. 1 by a pivoted lever 75 connected with the stem of the knife and carrying a roll 76 riding over a cam 77 on the supporting frame.

The cut sections ejected from the ma chine may'be stacked on a suitable supportpassing out of the for ing shelf or table 78 at the discharge end of the machine.

If it is desired to cut the cast sections in shorter'lengths this may be done by means of a lever 79 pivoted at the side of the machine at 80 and carrying a knife 81 to cooperate with the relatively stationary blade so as to drop the cut section thereon down so the slug just cut engages the top of the rear slug and the front faceof the packer 88 carried by an arm 89 dependent from the knife lever. On the rear stroke of packer 88 the slug drops between the packer and the rear slug. The cut sections are this automatically packed in a galley at 90. The hook 86 has a trip arm 91 engaging an abutment 92 soas to be automatically released t -wapredetermined point in the up stroke of the'knife handle.

As an aid to the cutting of the strips in the desiredlengths, I have shown a gage 93 on the shelf 83 against which the ends of the strip may be placed. .Tliis gage is adjustable for different lengths and a scale may be provided to assist in the adjustment of the same.

My invention, it will beseen, makes it possible to produce leads, rules and slugs of typo raphical matter" in finished form and ready for instant use, rapidly and by a continuous casting operation. These castings, furthermore, are free of any inherent lines of weaknesssuch as are naturally present where fused joints are relied on to connect successively cast sections; The pressure employed in filling the mold chamber and keeping it filled during the casting operations is of great advantage in that it consolidates the metal, forming uniform closegrained castings, assists in ejecting the cast pro-duct and prevents the drawing out mechanism from attenuating or otherwise weakening the castings.

To assist in a quick but not too-rapid metal end thereof by air gaps Eli and the upper and lower mold-blocksmay be watersetting? of the'nietal', the exit side of the mold is" preferably is'olatxl from the hotdrawing the cast product from the fexit end all) of the mold.
