This invention' relates AtoA finishing devices for castings, and has for its main object and feature to iinish a casting' ot the character that may be produced by the machine shown in application Ser. No. 5%05481, tiled March 2, 1922, and the present application is a division of said application Sei", No. tiener. y
In the accompanyinp,` drawings the invention is disclosed lin" one concrete and are! Jerred form in which:
Fig. l is afront elevation of a finishing device embodying one form of the inventlOll;
Fig. 2 is a vertical section of the parts shown iir Fig. l, substantially midway of the device on the plane of line 2-2 ot Fig. l.
Fig. 3 is a vievv similar to Fig. l but with one of the clamping` members and knives removed.
Figi l is a vievv similar to Fig. 5l but with parts broken away and in section and with castings in position.
Fig. 5 is a viewv somewhat similar to Fig. 2, bat partly in elevation, and partly in section with castings in position.
Figi. 6 is a' horizontal sectional view showing' the device in plan.
Fig. 7 is a view in elevation of a casting betore it is subjected' tothe finishing operation.
The casting to be acted upon is shown in Fig. 7 Where it Will be observed that casting 1la has an overcast or sprue 111" which is substantially in the termV ot a T-shaped head and by means ot Vwhich it is sustained by support)a located on either side oi a stationary knife 6'0". The casting` may obviously be placed onthisv support by hand but. as it is desirable to avoid a .separate handling, said casting is preferably carried automatically from the mold and deposited on said support in the manner described in said application Ser. No'. 546,481?.
Reference numeral Se md'eates a inor'fablfe knife mounted on a horizontally movable supporting` slide 65 moving in ggii'id'eivays 'termed in brackets GG carried by the trame. Looking at the m'ova'ble knife in plan it Will be noted that it is disposed at a slight angle to the stationary knife so that a shearing); cut Will be imparted` to the Iinetal.' rlSlie )lane or these knives is coincident with the line that separates the overcast or sprue ffl" serial no. *xsone-1".
trom the cast 1la proper so that the 'iT-head 55 is severed trom the main part of the casting. The movable kn'iie may receive its motion -from any suitable source such as by means ot rook arms 13 that extend through openings 67 in the supportinp,` slide. For the purpose oi2 holding the casting lirinl'y While the trimming or cutting operation takes place, l provide a yielding vise or clamp consisting of a clamping` plate 73 carried by a pair of push rods 74 slidingly mounted in bearings termed oir the underside ot sliding support G5, Suijroundingl each rod is an expansion spring T5. Facingthis clamping plate is an abutment plate 76 yieldingly held by springs 77 in a' posit-ion slightly in advance ot the cutting edge of the iined knife. llVh'en sliding` support 65 advances, springs i5 are thereby compressed and, these springs being stronger than springs 77, the backing plate ot the clamp is moved against solid cross traine F. lfhen sliding support 65' is nffithdravvn the movable clamp 73 is likewise Withdrawn and springs 77 will then` push back plate 76 inward' thereby stripping; the cast from the stationary knife and allowin?,z said cast to slide do'rvn between the clamping plates to'v support 80'.
The cuttingv elements just described are spaced some distance' from the lower' end ot the casting 1'no'l'c,`tli`ere being;y an openingin the framework at that point that opens on nielti'i'ig pot A. Overcast 1lb when held on siip'port 59 is therefore slightly above said melting pot. This arrangement is made for the purpose of permittii'ig the severed overcast or sprue il to be expelled or ejected into the melting pot. The means for accomplishing this are as follows: 68 indicate tivo rods, entendi through mevable knife blade 6e, and carried by txvo arms 69 mounted on a small rock shaft 70 movably carried in bearings on the underside et supporting' slide Rods 68 are surrounded by springs 68a' and are bent down." at their outer ends to coi'ilorm to the ann-le ot the 100 knife and are 'flat and somewhat flexible as show'vn. 7l indicates a projection on shaft 70 `for engagement with pinTQ on the side frames. liis supporting slide G5 advances, to sever the inetalspii-oject-ion 71 engages pin 72 just prior to the time the overcast is out oil, thereby tilting arms G9 so that when the overcast is severed, said rock` arn'isy 69' will make a quick forward motion and kick the overcast l1b into the melting pot. Springs 682l retract the ejector on the. return movement of the slide.
Support 8O on which the cast proper 11'"- 'drops may conveniently be in the formv of two members spaced transversely of the mas chine on which slide upright supports 8l.
78 indicate packer arms pivotally supported on red 79 and actuated from shaft 46 by means of the yoke 78a carried at the lower end of packer arms 78. As has previously `been described shaft 46 is carried by rocker upper end of which has extensions resting on theI support, means 'for removing the upper end of the casting including the exten sions to free it from said support, a second support, below the rst one, on which the casting' is delivered in an upright position after its upper end has been removed, andL a packer for moving the linished castings facewise while in an upright posit-ion.
2. A casting finishing mechanism including: a support for sustaining"v a casting the upper end of which has extensions resting on the support, a clamp below said support for clasping the main portion of the easting, knives for shearing ofi the top of the casting including the extensions while the main portion is clamped, and means for stripping' the main portion of the casting from the knives.
3. A casting finishing mechanism including: a support for sustaining a casting the .upper end of which has extensions. resting on the support, a clamp below said support for clasping the main portion of the casting', knives for shearing oli' the top of the casting' including' the extensions while ythe Vmain portion is clamped, and an ejector for ejecting the top of the casting from the inishing mechanism. j
4. A casting inishing' mechanism including: a support for sustaining a casting` the upper end of which has extensions resting on the support, a clamp belowsaid support 'for clasping the main portion of the casting, knives for shearing oil the top of the casting including the extensions while the main portion is clamped, an ejector for ejecting the top of the casting from the finishing mechanism, and means for stripping the main portieri of the casting from the knives. i
5. A casting finishing mechanism including: a support for sustaining a casting the Lipper' end of which has extensions resting on the support, a clamp below said support for clasping' the main portion of the casting, knives for shearing oli the top of the casting including the extensions while the main portion is clamped, a second support, below the clamp, in which the casting' is delivered in an upright position after it is released from the clamp, and a packer for moving' the finished castings Vfacewisewhile in an upright position.
6.,A casting finishing mechanism including: a support for sustaining' a casting the upper end of which has extensions resting on the support, a clamp below said support for clasping the main portion of the casting, knives for shearing off the top of the casting including' the extensions while the main portion is clamped, mean's for stripping the main portion of the casting from the knives, a second support, below the clamp, on which the casting is delivered in an upright position after it is released from the clamp, and a packer for moving the finished castings facewise while inv an upright position.
7. A casting' finishing' mechanism including: a support for sustaining a casting the upper end of which has extensions resting on the support. a clamp below said support forclasping the main portion of the casting, knives for shearing oli the top of the casting, including the extensions while the main portion is clamped, an ejector for ejecting Athe `top Lof the casting' from the iinishing mechanism, Aa second support, below the clamp, on which the castingis delivered in an upright position after it is released from the clamp, and-,a packer for moving the vfinished castings facewisewhile 4in an upright posit-ion.
