' (o1 .'22-so) I 7 Claims. -:'Ih.ls invention relates more-particula y t om ara-tus for chargi-ng a melting not used on tvpes t ingmachines and our object is to devise simple apparatus of "this nature which may be manufa tur d ch aply. w ich may be r adily-a ta hed to -existing ma hin s, which will be automa ic. in op rationand w ich may be easily adjus ed to vary the'amountied.
The invention is fill'l-Y-idBSCll'bfidi fiHd illustralifld, ay of xam le. in theaccomuanyin drawiug'in which.
Figure lzis-a longitudinal section, partly in side elevation oi -ou invention appl ed towa machin having a tiltable melting pot;
Figure a plan view thereof; and Fi e-8 a cross-se tion ion the. line, 3-3 in Figure :1.
' --In the drawing like numerals of reference ind cate eorrespon ingpa ts in t e different figures.
.1 is a tiltable melting pot of a typesetting machineof ordinary construction and operation.
' l he Pot is pivoted at 2 on the frame 3 or the machine and is oscillated thereon to discharge netal through the channel 4 to type forming molds, not shown. The-means for imparting oscillatory movement to the pot is not shown since various means of doing-so are well known in the art. The usual plunger 5 andcylinder or well ien ure the discharge of the metalto said molds. and the usual manner. Means,for feeding used slugs 1 automatically to the p t to replenish the supply of metal therein are provided andsuch .means comprise a stationary guide 8 secured to W- e t part ofthe viramat of the typesetting machine. The gui has sides 9 which are securedtogetherat each end. in spaced relationship Pay-cro s bars 10. Aired I3 is slidably mounted in-open bearings l2 formed in upwardly extending portion ll so that the rod may bereciprocatedtherein relative to the guide and may --.be readily removed tromthe bearings. Atollower l4 .slidably mounted on the rod IScarI-ies a pawl which enga esserrations or ratchet teeth =16 fo med, on "the .rod whereby a movement vin one direction or the od will. cause a orr sp n movement of the. :Iollower. I
To reduce lost :motion between the rod and the followen'a, plurality-oi nawls I5 of different lengths are employed so that one of the pawls will be positioned for early engagement by one of the teeth 16.
Usually the used slugs 1 are carried in galleys I! each having an open end so that the slugs may be pushed therethrough to discharge them therefrom. The guide Bis adapted to receive a roller :11 and isrrovided withasetscrew L8 to ecu e theeallcy in .position- If efollower d4 enga es the slu s 1 atamoint rem te from the op n end of the alley and is zhrovided -with a cramping member .19 tor crampin en agement with the bot om or the galley to loci; the rollower from return movement awhenthe rod :13 is returned to its initial position. Thus the :rod impa ts an ntermittent movement n the feedine direction only to he iollower. Moreover. the teeth It extend along e rod '3 tea p in whereby the follower isintermitten ly 'moved on y a sujfliei n di tance to discharge all the slugs in the galley. Wh n thispoint is r ached,
the pot is tilted .to discharge :a portion of its contents, to engage a detent, or .a hook 2i pivotally connected with a collar 22 which is secured to the end of the rod l3 and is.longitudinally adjustable thereon. The stroke of the rod 1.3 and thusof .the follower l4 may be varied relativeto that .of the shoulder .by shifting .the acol1ar22 and thus the-detentll relativetothe shoulder whereby the lostmotion may be varied. v.Therod 13 may be returned toits initial'position by any suitable. means such as-one or more. springs 23 secured to th rod and .to any suitable stationary part such as the adjacent upwardly extending portions of theguide 8. Anysuitable stopmeans may be provided-to limit the return movement of the vrod .to (maintain the desired setting-of the detent 2| relative to the. shoulder 20 on the next tilting aotionof the pot l. Such stop means may comprisea sleeve 33 adjustably secured to the rod 13 for engaging the said portions, 1 I.
To stop themoperation of the feeding means, the drive connection 20, 2| between the pot I and rod l3 may be automaticallydisconnected. The detent 2| .carriesra shoe .oran'anti-frictionroller 24 which normally runs on a surface 25,,suitably secured to or formed :on vthe. bracket 32 behindthe .shoulder zflt A lever 25 pivoted at 21 at the end of the surface 25 has one end pivotally connected with the spindle 28 of a float 29. The spindle 28 is slidable in a bearing 30 secured to said pot. When the level of the metal'in the pot rises or lowers the float will lift and fall thus rocking the lever. The free end of the lever 26 is inclined at 3| and normally the inclined end 3| is positioned above the roller 24. However, when the metal in the pot reaches a predetermined level the float 29 will rise to swing the inclined end 3| into the path of the roller 24 and cause it to run up the incline 3| and along the lever 26. The detent 2| is thus moved to an inoperative position relative to the shoulder 20. The rod l3 and the follower l4 are thus not moved whereby additional slugs will not be fed to the pot l until the level of the metal therein drops sufiiciently to cause the lever 26 to be moved out of the path of the roller 24. When this occurs the feeding means will again'resume its function.
What we claim as our invention is:
ment thereof relative to that of the shoulder the rod; and cramping means carried by the follower for engaging thegalley to resist movement with the rod during its return stroke.
