Be it known that I, JOSEPH Noonnox, a citizen-ot` the United States, and a resident of Cheviot, Hamilton county, State of Ohio, have invented a certain new and useful Apparatus for Backing Up Electrotypes; and

I do declare the followingto be a` clear, full, -and exact description ofthe invention, at-

tention being called to the two sheets of drawings, which accompany this application and'form a part thereof.

This invention relates to amachine for backing-up Lelectrolytically produced printmolten condition, is poured into the pan,

. stantially a 'soldering connection, formed ing-faces for printing type-matter, illustrations etc.y These faces, Jthe result of the. electrotype-process`,-are metallic shells, cop-- vper being generally used, which on accountof theirI limited thickness require strengthening vto render them available for use in printing'. This isdone by what is called backin these shells with a back formed yof metal for which a suitable alloy or so-called typemetal is' vgenerallyused. The usual procedure for `formingA this backing 4is by placing the metal-shells face' down upon the 'bottom of'a flat' pan, after which the metal to be used i01- backinfgithem, it being in generally by means of a hand-ladle, and

floated over theback ofthe shell, so as to closely adjust itselfl against the same` and 'to vtill into the many recesses which-make up the type-face. The pans are of a depth to permit them to receive suicient vof this metal to, vcause formation of -backing of ,proper thickness, this thickness 'being ap- .proximatelyione v`fourth of anmch more and this metal whereby it is backed, 'is subsoldering j oint, and prelimianalogons to -a by. deoxidizing and luxing gans, plan their edges and mounted upon wooden bases after which they are ready for use inthe printing press.

The subject of this invention concerns an'.

In connection there are means providedior supplying heat necessary to apply, the required tinning to the back of the shells and to prepare for 'luxing the backing metal,

.Further there are means-to discharge molten -ing in -diferent positions; Fig. 4, is a side- Y.

metal into each pan and 1n proper quantity i to float over the back f theshells to suflicient depth to make backing of proper thickness, this` discharge being `by preference automatic and under .adjustable control. l

Finally there are means to apply a cooling medium jto cool .the metal with sufficient rapidityto permit removal from the pans of the backed shells and replacing of other` movement of the carrier.y

' shells to be backed without interrupting the.

The carrier-consists of -a circular frame A, supported for rotation in'v a ,horizont-.1 position at the -upper end of a standard 10,

and of brackets a, which in desirable num-v .bers extend radially from the periphery ot TheseH brackets serve' for supporting the pans B, which receive the shells C to be backedand the metal used, for A. the purpose. The carrier-frame with the.

this frame.

brackets `is rotatedby suitable means at a moderate speed appropriate for operation. These rotating lmeans consist of an internal gear 11, provided on frame Ay and engaged by suitable motive lpower as Afor instance by an electric motor '14 and by vsuitable intera pinion 12 at the upper end of'an up-f .right shaft 13. This latter is actuated by v im l l metal may be -remelted after having been venient transmitting gears arranged to ob? tain proper speed. The discharge of the molten metal is timed so as to* occur only While a pan passes in proper position to receive it. The quantityV discharged at that time is of course so -apportioned that/the metal rises above the shells sufficiently to iproducebacking of the desired thickness.`

The same quantity is released at each discharge inasmuch as the pans are all of the same size irrespective of any variation in the size of the type-shells, the' sizeof the pans being so asto be capable of receiving the largest shells which may be made. No'4` Waste results however because the surplus cut off" even with the edges of the shells When the resultant type-plates are trimmed to size.l

In order to.l obtain the necessary quantum yof metal in the 'limitedjtime-during which discharge is available, metal is released simultaneously from a number of.openings above a pan. They advantage of a discharge of this character as against one from a single, but larger, outlet is that it prevents buckling of the shells, or curling up -at their edges, Which, Wouldiresult from (the limited t contact ,ofl a concentrated discharge. of

' ladle isused. AForfsuch purpose I provide y metal, an objectionable eifeotconnected With the fpouring of the. metal when the handa discharge-head D, which hasa number of outlets d' arranged in a line substantially radial to the carrier, the length of the'row of outlets being arranged with respect to the length, radially considered, of the pans, and

Vthe row being so' positioned as to be, above the path of the pans and entirely within the same. See Fig. 5. y f

Discharge from the head is controlledlby controlling the supply thereto and is ob-` tained bymeans of a lvalve 15. `This valve i might be actuated manually, but by pref-l erence it is actuated by means operating automaticallyA and inA a manner that discharge' of metal starts as soon as a pan 'has passed fairly below the dischargelhead and is caused to stop again before the same pan 'has passed yout from below the dischargehead. Inasmuch as variation in the Weight fof the 4bodyxof molten metal lying back of the discharge-head has a tendency to modify discharge from this latter quantitatively .and in fa-manner affecting the thickness of the baclnfng to be produced, it is desirable to-arrange for the maintenance of a con-- stant body ofmolteu metal from which ythe s. discharge-head is supplied. For this reason and instead of connecting thev discharge-V head directly' to the melting-pot E, I 'conf nect it to an interposed pot 'F, which receivesthe metal in molten condition from the meltin .-pot and holds it in readiness for supplying the discharge-head. A Acon-I conditions and arrangements,

duit e connects the meltng-pot-wth this supply-pot and a constant body of metal is maintained in this latter by means of an automatically actuated valve 17 Which controls passage through conduit e. This providesa-lso metal Iclear of dross Whichl latter remains in pot E. The actuation ofvalve V1'? is preferably by means of a ball-float 18 vvvhich .rises and falls with the level of the metal in pot F and by-f'its obvious connec- .tionv and operation actuates valve 17 infthe desired manner.`

G indicates a suitable furnace forisupplying heat below melting-pot E.

Valve 15 is actuated to cause flow of metal from the discharge-headinto the pans which pass below it, by cams 19, Which move With the carrier, one being provided for each pan.

. These'cams pass under and lift a rod 21 and an arm 22' connected to it toy which valve 15 is connected by a stem 23; Prompt closingnaction of the valve is had by means of a Weight 24:. Its position Within the pot Which contains vthe molten metal prevents possible interference lby congealed metal. Rod21y is sustained by a braced bracket 25 on which it moves. Removal from pans B of the shells, after they have been backed, can of course not occur until the metal has congealed to a consistency sufficiently rigid to permit this to be-done. A

The placing ofshells to be backed must occur sov far in adyance beforeV reaching the discharge-head as to permit application of" heat necessary for tinning them, which tinning must have been completed before the shells arrive below, the. discharge-head Where they receive the backing metal. i The location of thesepoints Where the shells are' handled in this manner depends on special determined by the size of the carrier, the number Aof pans.A carri'ed thereby and the speed For present purposes and conditions itis assumed that' the removal of the. ybacked lshells from vthe otherY shells to point approximately opposite thedischargehead. These shells, while passing from this point and before reaching the discharge Yhead, are .tinned on their before stated, to prepare't m for receiving the backing-metal'.

In this case the shellsfare first acid-treated and the tin in convenient shape, as for in stance foil, is placed. Heat is applied in suitable form, to cause melting of the tin. This is Vdone by burners positioned below the pans and accompanying them for part of their travel. is complete as they pass under the discharge-head of the'pouring-device where they receive the backingmetal. The discharge of this metal is effected by ycams 19 which act upon valve '15 in the manner described. At that time the burners which have moved with the pans slip back and the burner under that particular pan which is receiving metal does not further follow it. Passed beyond the discharge-head, the backed shells are subjected to an air-blast, to permit their removal in due time. The proper quantity of metal is discharged each time into each pan and this discharge is under perfect control as to time and quantity by actuation accordingly of valve 15 which admits the metal to the discharge-` head. 'Such actuation is obtained by positioning cams 19 correspondingly and by arf ranging their length and height upon which i as when ,dipping andV pouring the metal factors the lift of valve 15 and the duration of its opening depends. Various expediencies for exact adjustment of this control suggesttliemselves readily. The interposi tion of supply-pot F, between the discharge-head and the melting-pot insures clean metal, free from dross which remains in the melting-pot where it floats to the top. As a result, spongy plates are avoided and clean casts are obtained of solid metal free from cavities and bubbles.

The work of the tender is not as onerous with. the hand-ladle, since he handles no molten metal at all and his position is remote from the furnace and from the pouring-device where the metal is the hottest. Having described my invention, I claim as new l.
