11o/all fir-'Icom vit may concern:
Beit known that I, WiLLrAM 'W. `DUNN,ot the city-mul' county of Sun FranciscqState of California, have invented certain new and useful Improve.
jznents "in linchinesfor lMaking Typeg and I do hereby declare that the following is a full and exact descriptionof the saine, reference being had to the accompanying drawing and to the letters marked thereon. 4
'My'inrention relates to that class oi' machines for casting type which is provided with devices for breaking olf the superfluous metal and dressing the type, a,ndf consists` in certain details of construction which will, hereinafter .more fully appear.
In the annexed drawingliigure 1, `sheet 1, is a perspective -view oi' a nmchine embodying my invention; r
Figures 2, 3,.,4,5, ando, sheet 2, and
Figures l, 8, 9, and 10, shcetl, are details. i Lilie letters refer-:to like parts irreach ofthe figures. .Y
The melting-pot u. is heated by a furnace, not shown.in-thefdrawing,and v v i The'cavity b is kept continually supplied with molten metal. l v
The plunger c hasaiverticalreciprocating inotion imparted to it by suitable machinery, not shown.
1 l This plunger is shown in its highest position in iig.
2', ,sheet` 2, in which position the cylinder or well rl grill ll with metal through the passa-gcc. Thefectioualarea of thelpluuger is such, and its lengt-h "cf `stroke `so adjusted, that iudcscending it 'will displace -justenough metalto formone type, and force itout through thepassage f up' through passage g, raising the cylindrical ,valve hand discharging through the nipple t to the carrieror spider j andthe mold. v Y. r
v--\Vhcn,the plunger chegins-its upward stroke thc valve h will -beimmediately forced downward by the spring o closing the passage to the nipple.` Increasing the length-ot' the-.strokryof the plunger will compensate.for4 leakage around orimperiect illmg-'of-the plunger' or valve. f f ",'To prevent thc excessive heating `oihthomold a screcl-r, 1.', is provided, bctween'which audvthe. ineltf ing-pot :urair passage shouldi he made. l l
lhe'nioldonmntrix consist-s of three picccs, lV mn,
2 and 3, all orv cil-her nl'- whichcan hezreadilyfrcniovedor-cxclnuiged at will inordor to molddficrent forms-of type. g l Y y. I lffiheffrcc' i'ignlu-r sp: 'c'rnrlormcd by the pieces l and nz, i closed at its outer eudby the rocking piece ledig. 2, @upon .whichthc matrix 'for the letter orl char- Sterf is loi-mcd;- and a scparate-V rocking piece, n, shnldhr provided' for cach character or lettci;
The molten metal flowing from the nipple fills not only the mold out the opening in` passage 78, fig. 4, in Ythe end of the arm ot the carrier or lspider j, and
forrns between the spider and Athe typen gate of 111176132171.
'v lAs' soon as the casting is thus performed the vmold is opened and the type released'by means o f the f'ollowing devices, the motions of whicliare'derived from the eccentric q', fig. l;
Y First, the .upper part L of the'inold is raised up out of the way andreturned to itspositiou by means of the hinged plate 1', to which is attache-d the swivelbox nut s, tig .1, in which is4 secured by ineansof the `drop-catch t, the h orizontalarm u.
The arlnu is secured by means of the sliding' arm fi: and screw 'w to a vertical rod a: therod :l: is -con nected by means of the swivel-piu y tothecam c, fig. 1.
motion throughthe intervening mechanism to the upper piece l of the mold, said calu, .d being hinged at l, and receiving'its' motioufroma pin, 2, on the extremity 'of the rock-shaft arm 3, g. 4.
able lever 10 act-ing` onf-an. arm, 11, attached to thespring 12."
vBoth the rock-shaft and the lever 1Q areoperated by the sliding-cam plate, 13, g.,1, and the cam-plate 1 3 is iinpelled by the rod 14, connected with the adjustable rock-shaft arm' 15 of shaft 4.
As soon as the type is released from themold, it is carried lover byy the spiderj anddeposited on the type lan'dingor cutter-plate 16, grasped` or held in a 'l proper position by the foot 17 and forced through between cutter 18 and breaker 30, and cutter-platcl .'hy t-he type-slice 19 onto the cutter hed-plate 20,
lg.7. L The required i-'eciprocating, inotioiris-imparted to thc' slice by means of theguide-platel 21,. counectv ing-rod 22, roclishaft 23, arms 2-1`and 25, 'con'` necting-rod 26 lever 27, connecting-rml 28,'and crank-29. l i A y: f"
.,.lhe.typclai1ding or-cutter-plate 16 is rigidly sel cured to the bed-plate 20, and is'- providedtvith l'L- agonal cutter 3l, that plane and trim or sha1-fe the underside `of the. type as it passes over theni,wl1i le the cutter-*18trirnsthc top. v
Breaker 30 separates the gate-from the. type; thc gate being still retained iu the spider-arm is carried 1 )ating the throw of the lever 40.
secured to a angc on theA shaftl 33, consequently the shaft 33 is rotated one-sixth of arevolution each time that a type is cast by means of the ratchet- .wheel 34, stop-wheel 35, stop-pawl 36, and pawl-arms and pawls 37 and 38, connecting-rod 39, lever 40, and
eccentric v41.
The"rod of eccentric v4l is Aconnected to lever 40 b means of'a )in secured in a slot 4.2 in the le'ver.
.l w A .s i
rlhe slotted connection 1s for the purpose of regulhe plate or mold-seat 42, carrying the matrix and -the machinery connected'with the eccentric q', is
hinged and secured and adjusted by the screws 43 and set or binding-screws 45- to a vertical plate drmly attached to or forming a part o f the moving or sliding bed 44.
-The sliding bed 44 is forced toward the meltingpot by the cam 45 and roller 63, and toward the cam 45 by a suitable spring; said roller' and spring are so constructed and adjusted that whe" the moldis being filled the face ofv the mold will press the arm of the carrier tight against the nipple and prevent leakage of metal, and afterthe mold is filled separate the .metal from the end of the nipple by moving both the carrier and the mold away from the nipple. .ForI the better adjustment oi' the motion of the moving-bed a set-nut, 46, is` provided.
For the purpose of imparting the required corresponding motion to the spider an end-long motion is given tothe shaft 33 by means of the collars 4-7 and 48 betweenwhich works anarm, '49, rigidly attached to the .moving-bed, figs. 10 and 1.
'.l`o`the moving-bed is also attached another stout arm, 50, at=the extremityof which is a set-screw, 5l, that provides a support forthe extremity of the arms of the carrier during the operation of the punch 32 in driving out the gates, fig.
The foot 17 `is operated by means' of the cam 52,l
the lever 53, rod- 54, `lever 55,-.spriug 56, and adj-usted by means 'of a set-screw proiecting through the plate 57.
The cutter-bed plate 20 is position to the top of the frame 58.
Frame 58 is secured to the principal frame of the machine by the set-screws 59, and adjusting-screws 60, 'andslot 62, in such a manner as to be readily adjusted in regard to height, and according to the thickness of the type.
The box-nut s, iig. 1,is swiveled for the Vpurpose of obtaining a direct and even pressure for causing the face or parts of the-mold to come squarely togoth er.
' lThe entier 18 is secured to the holder 64and is raised or lowered to conform to typeoffdiii'erent thickness by the slidingr of the holders on the pillar or rodG, adjusted and .secured by the screws 66,' thc .pitch of that part of screw 66 .that works in the top` plate of the vholder-being dii'crent from the pitchl of the part working in the pillar or rod (i5.
The melting-pot may be leveled, tilted, oradj usted by means of the adjusting-screws 67 and the holdingdown screws 6 8.
The .required horizontal motion is imparted Ato thc punch or needle 32by the eccentric 69, eccentric-rod 70, cani 71, pin 7 2, guide-frame 73, sliding-plate 74, and clamp 75,'ligj5.
The office of thc foot- 17 is very important in holding the. 'type firmly down -ou the type-landing, and preventing it from being turned or tilted over by the cutter 18 or being thrown out of place by .the leverage of the gate over the breakers 30.
-The operation of the slice yin bearing uniformly on secured in an inclined` man the type throughout its length and-forcing said type laterally thnough the cutter, prevents the possibilit;`
of bending oninjuring said type during` theftrimming,
'to all the'moving parts.
The. holes or recess 78 in the extremities of the arms of the carrier, or spider'j, are tapered, having Y their largest end toward the mold.
These holes are thus tapered in order to prevent: the gate .from being drawn through them toward the nipple, and -thus breaking the gate off of the type while the type is still in the mold.
The screen 7a is an important de vice, for the reason that without it the lnold would become so heated by the radiation from the melting-pot that the metal wpnld not have time to chill in them unless the casting was proceeded with much more slowly than is necessary with my invention. s Y
'.lhe adjusting-screws 67am particularly required to adjust the height o f the nipple to the center of `the holes 7S, in the carrier j,.aiter the meltingpot has become expanded by heat, of course, the screws 67 maybe placed in the forward lugs `of the melt` ing-pot it' desired, or wedges' may be used in their stead. y
rlhe nipple i, foot 17, and punch 32, are equidistant from each other and from the center line of the shaft 33, their distancev from the` center line of the shaft being just equal to the distance of the center of is, if only three arms are used'.- the shaft should make one-third ci' a revolution for each type that is cast; or, if nine arms are used,.one-untl 1 of a revvhinging, securing, or 'adjusting the mold-seat 42 to a v bed by the screws 43 and 45.
' Neither do Iv claim, broadly, operating the machin ery connected with thc casting of type by a revolving shaft, nor the employment of the cam 45 and roller (i3 for the purpose of causing the matrix or mold to approach and recedc from `the nipple i; but
lVhat .I do claim asnewin machines. for making type, and desire to secure by Letters-Patent, is-' l. The eccentrics q', and rod q, arm 5, rock-shaft fi, adjustable arm 15, rod 14, cam-plate 13rock shaft G, arms 7 and S, setfserews 9, adjustable lever 10, and spring l2, combined and arranged substantially as described, and for the purpose set forth.
2. lh'e cutter 18 in combination with the holder 64, pillar 65, and screw 66. A The punch 32 in combination withthe arm 50 and secscrew 51, substantially as and for the pur- `pose set forth.
4. lhearrangeinent of the eccentric 69, rod. 70, cam 71, piu 7 2, 'guide-frame 7 3, sliding-plate 7 4, and clamp .75, when employed in connection. with the punch 32, as described.
5. The presser-foot 17, in combination with lever In testimony whereof I havehereunto set my hand 55, having the adjusting-plate 57 and spring'56, as `a.nd seal. l shown and described. l
6. The combination of the frame 58, the cutter-bed plate 20, cutter 18,bi'ea.ker 307 and cutter-plate or Witnesses: lgype landing 16, with the foot 17 and type-Slicer 19, CALEB T. Fn', when the parts are arranged as described for thepur- O. W; M. SMITH. pose setrforth.
