To all whom it may concern."

Be it known that I, VVILLIAM S. llns'ron, a sident of Chicago, county of Cook,; and State of Illinois, have invented certain new and useful Improvements in Casting Apparatus, of

to provide an arrangement of the molds on a traveling and preferably rotating carrier. together with improved-means for automatically opening and closing the molds and discharging the castings; 'to provide an. im-

. proved arrangement whereby the closing ofthe molds operatesto form aniininterrupted trough along which the molten metal may run from mold to mold while the latter are filling; to provide improvement-sinthecon-. struction of the working faces t themold and to provide improved automatic means for securing inserts andfthe lik'e' ifthemold cavity; I Y

The invention'consists in thefeatures or construction, combinations and arrangements of parts hereinafter set forth, .illus trated in the accompanying drawings and more particularly pointed out'in the appended claims. i

A series of traveling molds are-mounted upon a suitable .carrier or wheel frame that is preferably built up of structural steel. In the form shown, the carrier or wheel. frame comprises a central hub 1 jo urnaled upon a short upright spindle or shaft 2, a series of radial frames comprising upperand lower angle bars 3connected by brace bars 4-.

the ends of the radial members or spokes of the Wheel frame, are secured upper and lower circular angle bars 5 The spindle 2 is mounted upon a pedestal 6 so that the wheel frame may rotate in an approximately hori- A row of'anti-iriction; balls 7 v(see Fig. 2) are interposed between suitable bearing members .8 and 9 secured-tortltihub .1 of the wheel frame and to'the upper end of the pedestal 6. 3

. Rotation is imparted to wheelframe .or mold carrier preferablybyineans of an annular rack 10 secured to thelower radial angiebarsii and a pinion '11 mounted upon a vertical drive shaft 12 and meshing with the teeth of the'rack 10. The drive shaft; 12 is mounted upon a suitable beariIIglS carried by the pedestal 6 and may be driven by any suitable application of power. l

The series .oi" two-pair molds, each comprising a section 14 and a section 1.5 are carried uponthe periphery of the wheel frame or mold carrier, and preferably between a series of supports or plates 16 secured in radial position to the upper and lower rims or circular angle bars 5 of the wheel trains or mold carrier. H

' For convenience in making rfepairssnd the like, each mold is preferably"mountedupon the wheel frame or carrier Independent oi the other 'molds and in such manner that itfinay readily be moved. For this purpose, the

outer, or what may be termcdthe movalde section 15 of each mold, is carried iip'on the I inner mold section, as hereinafter described,

and the latter is ren-iovably fitted between two ofthe adjacent radial supports or plates 16. For this. purpose,'theksinjpoits 16 are T-shapedattheir inner edgesor provided vided on opposite sides near their inner edges, with vertical ribs 18, all as clearly shown in Fig. 1. The inner or fixed section 14 of each mold (see Fig. 8) is shaped to "snugly between two adjacent radial supporting plates, its inner face abuts against the flanges 17 or T shaped edges of the plates and the sides of the mold section 14 are provided with vertical grooves engaging the ribs 18. The outer mold sections 15 are also shaped to fit snugly between the radial plates or supports 16 in closed position and the upper portions of both the inner and outer mold sections are enlarged laterally so as to extend over the upper edges of the supports or plates 16 to, tie central radial line of the supports, as further shown in Fig.

1. In this way the upper portions of the inner mold sections 14 a mt one against the other and the upper portions of the outer mold sections 15 abut in a similar manner when in closed position. The upper portion of the inner mold sections 1.4,are also off-set so as to overlap the outer edge of the wheel frame, as indicated in Fig. 2. In this manner, the molds are rigidly and securely held in. position upon the carrier but may be readily slid in vertical direction to osition on the carrier or as readily remove there from for repairs, renewals and the like.

Each of the inner mold sections 14 is provided at its lower end with a downwardly and outwardly projecting part 19 which carries the swinging support for the outer mold section. This swinging support or lever 20 is preferably formed of two members which extend on opposite sides of the projection 19 and are connected thereto by a transverse pivotbolt 21. The upper ends of the members of the swinging support or.

lever 20 extend outside of a pair of rearwardly projecting lugs 22 (see Figs. 5 and S) and are pivotally connected thereto by a transverse bolt 23. The lower ends of the members of the swinging support or lever 20 are secured to a counter-weight 24 which tends to hold the movable mold section 15 in closed position. supports or levers 20 for opening and closing the molds is controlled preferably by means of a cam track 25 carried on a series of pedestals 26 (see Figs. 2, 3, 4 and 11.) and which engages a series of rollers 27 on the swinging supports or lovers 20. Each lever 20 1s pr0vided-with a roller 27 suitably journaled upon a block or mount secured between the members of the swinging lever (see Figs. 2 and 5). The movement of the mold section 15 also controlled by a bent link or swinging support 29, the inner forked. end of which is pivoted to a stud 3O screw threaded into the lower end of the inner or fixed mold section 1%. The outer or upper end of the link 29 at the outer end is flattened and extends between the .mold section 1.5 to and. from tho mdld st ripheral surfaces of the rollers.

The movement of the sitiou which is shown in Fig. 2.

sensor lugs 22 on the outer mold section and is pivotally connected thereto by a cross pin or bolt 31. By reference to Figs. 2, 3, t and 11, it will be observed that the shift of the supporting lever 20 upon its pivot 21 moves the ion 14 to open and close the mold while the link or swinging support 29 operates to partially rotate the mold section 15 upon the pin 2? so that the mold section may be inverted (shown in Fig. 3) to discharge the casting and so that the mold sect-ion is also brought back accurately to position to close the mold. as shown in Fig. 2. In addition to the cum track 25, a second. cam track 2! is also prelerably provided upon the uprights or supports 26 that is arranged to engage a series of rollers 31;, one of which is journalod hetween a pair of lugs projecting laterally from the upper portion of each outer mold section 15.

In one complete revolution of the machine, the outer mold section 15 of each mold is opened and closed changing from the position shown in Fig. 2 to that shown in Fig. 3. then back to the position shown in Fig. 4 and finally back again to the closed position shown inFig. 2. This movement is effected by the stationary cam tracks 25 and 32 which are bent and twisted so that their working faces are arranged in dill'erent planes, to form proper tread surfaces for the

rollers

27 and 33 on the swinging supports 20 and on the movable mold sections 15. That is to say, the surfaces of the cam tracks are in all positions parallel with the axis and pe- A single cam track for shifting the swinging supports 20 might be suflicient, but as stated a second cam track 32 is preferably provided for as sisting in the controlling movement of the outer or movable mold sections 15 upon the pivot pin 23. With the arrangement shown, the cam track 32 operates to close the mold while the cam track 25 operates to open the same so that by using two cam tracks, the outer mold sections 15 are positively shifted in opposite directions and to open and closed positions. The outer sectionof each mold is opened to its full extent at the point indicated by the line 33 in Fig. 10 and at this time the mold section is in the position shown in Fig. 3. As the machine is rotated in the direction ofthe arrow shown in Fig. 10, the

cam track 32 is brought to bear upon the roller 33 of the outer mold section 15 and shifts the mold section first to the position shown in Fig. 4 and finally at a point indicated by the line 2-2 in Fig. 10, the outer mold section is brought fully to its closed po- The mold sections remain closed during a pm-tion ol' the revolution of the machine (in the form shown the molds are held closed through slightly over a quarter of a revolution) and when the mold is so closed. the cam track 25 is out of bent away into the shape indicated in Fig.-10.'

The cam track 32 might be depended on to hold the mold. sections 15 in closed position, but preferably other additional. means are provided to positively hold the mold sections m closed position. For this purpose; a series offiat springs ,35 (see Figs. 2 and 11) are secured to the upper edges of the radial supports or plates 16 and these springs are provided in their outer ends with shoulders or offsets 36. As the mold sections 15 are swung to closed position the laterally offset upper, portions thereof pass over the spring catches or latches 35 until the shoulders 36 on the spring latches engage the outer faces of the mold sections, as shown in Fig. 2, at the right hand side of Fig. 11. and in Fig. 5, to hold the mold sections together. As stated, the cam track 25 in the closed position of the molds, is not in engagement with the rollers -27 on the swinging supports or levers 20, so that theeounter-weight on the latter may freely eXti -t its pre'ssurcto assist inholding the molds in closed position and-to insure that the bottoms of the mold/sections willbe smlgly held in engagement. A pair of set screws 37 are provided on the outer face of each mold section 15 near its lower edge (see Figs. 2 and 5) and agamst which the members of the swinging support 20 bear when in closed osition to force the bottom parts of the mo d in closed contact.

When the mold-reaches a point a. in Fig. 10, it is necessary to release the latch 35 and for this purpose a lug or strap 38 is secured to the under side of the cam track 32- at this point. At the position a (see Fig. 10) the cam track 32 begins to curve away from the machine (see dotted lines in Fig. 2) so that the lug 38 is in position to depress the spring catches 35 and release the mold sections 15. At the same time the cam track 25. (see dotted lines the machine so that the molds maybe readily removed for repairs, renewals or the like without interrupting thcoperationpf thcmachine.

While the improved machine may be adapted to manufacture avariety of cast metal articles, the molds illustrated in the drawings are designed for the manufacture of railway brake shoes, and particularly that class of shoes provided withpreformed retaining, lugs and inserts of wrought iron or steel, and some of the features of the invention relate to means for holding the lug and the steel or iron insert or back in position in the mold during the cas'ting operation. I

In Fig. 3 the brake shoe is shown as just discharged from the mold and the retaining lug and back reinforcement of wrought ironor steel are shown, the latter by dotted lines. The lug and b ack are shown in full lines and held in position in the mold in Figs. 2 and 4.

The device for holding the lug and reinforcement or insert preferably comprises apair of jaws 39 arranged-within a cavity 40 in the back of the mold section 15 between the lugs '22- thereon. These jaws are ivotally mounted upon the cross bolt 23 am are providedat their ends with fingers or teeth 41' and 42 which engage the opening in the retaining lug of the insert. The jaws are provided with outwardly extending arms 43 which arearranged on each side of the flattened head or end of the link 29 and are provided with elongatedslots 44 -enga'gimgz; ec-

centric lugs 45 fixed to the head or end of the i I The shift of the' link 29 and of the eccentrics 45 fixed thereto r'elatively'to the arms 43 of the jaws as the mold section 15 3 moves from the position shown in Fig. 2 to that shown in Fig. 3, moves the jaws from the closed position shown in Fig. 2 to the open position shown in Fig. 3, while the reopen to permit the placing of the retaining lug, and wrought metal back in position. 3

The adjacent parts of the upper portions of the mold sections 14 and 15' are cut away to form a pouring trough or groove 46 cxteiu ling along or parallel to the parting lines of the mold. sections when the latter are in closed ()ne wall of the trougl'i is formed on the fixed mold sections 14 and the other 'on the movable mold sections 15 and since, as

stated, the upper portions of the mold sectionsrare in contact when in closed position, the trough extends continuously across all of the closed molds. The sections are preferably formed of cast iron and those portions of their surface which form the trough so are ,,-.preierelf ly providedwith o lining 4.7 of re ljrcctory materiel held in niece by wrought motel plates 48 detaehahly secured to the 5,,1nold sections by screws or the like, as indiceted in Fig. 1-. Extending from the bottmn oi" the trough 46 and in the parting line hetween the sections, are gates 4-9 which lead to the mold cavities. The portion of the man chine at the right hand side of Fig. 10 is slightly elevated so that-when the motel is poured into the trough at e point b, it will tend toilow through the trough in at dircction opposite to the movement ofthe me.- chine. The trough serves to guide the molten motel from mold to mold so thettwo or more of the molds, depending; upon the amount of elevation ol' the machine, may he filling at the some time. Referring to Fig. 1-0, the operation of the machine may he brieiiy described as Follows: The machine and the series of molds are moved. continuously in the direction indi-- outed by the arrow. tions arrive at the point 4i--4-, the inserts are put in place, as shown in Fig. 4. The mold sections are then gradually brought to the closed position shown in Fig. 2. As the molds a. )preaoh' and pass the point 6, they are filled with molten metal from a suitable spout or ladle, sll'surplus metal after each mold is filled fiowing on through the trench 46 which extends continuously over all of 11 1c closed molds into the next succeei'ling molds. .35 By the time the molds reach the point a the l castings are set and the molds are open to discharge the finished castings at the point 3-8. The molds then pass on to the point 4 4 where they are again provided. with in- 40 serts and lugs for the next series of castings.

The bodies of each of the

mold sections

14 and 15 are made of cast iron. The working faces, that is the surfaces exposed to the sction. of the molten metal inc be formed in tl1e cast iron body. Prelereh y however, the mold cavity is provided with so lining of wrought iron or steel or an alloy of iron that has a. considerably higher fusion point than the cost iron of the body of the mold section. if the mold cavity were formed in the cast iron body of the sections, the labor incidental to planing and fitting of the sections would have to be repeated each time the mold was discarded because burned or otherwise dsmaged, whereas a renewable lining of sheet iron or steel may be formed at smell cost.

'As stated the particular molds illustrn-ted are designed for the manufacture of hrske shoes and, as shown in Figs. 2, 7 8 and 9, the outer mold section 15 which forms the heck of the brake shoe, is provided with a. liu log 50 oi substantially uniform thickness.

formed between the p M molds, gates 49 and the vents 56, 57and 58' grooves, as stated, are at the top of the mold cavity and are so shallow that they chill the iron whenitreaches and enters them, thereby avoiding any material flow of the molten metal through the vent or vents to the BX- terior. If desired or necessary, half-round grooves or vents 58 (see Figs. 5 and 7) may be formed in the sides of the mold section and which extend horizontally from the back of themold section to the upper ends .of the passag'gesi 56. When the vent openings or groovesSS are-employed the lower ends of the vent passages 56 may be closed.

The casting of metal articles in metallic molds causes "the articles to be more or less chilled in. accordance with the properties of the metal employed. In someinstances it is preferable that the cast iron should be chilled little as possible, as for instance, in the larger portion of the working face of a brake shoe. To avoid such chilling the mold section 14, which forms the wearing-face of the shoe, is'provided with inserts 59 (see Figs. 2, 6 and 8) of non-chilling material, such as graphite or clay,-.or a mixture of the two. These inserts are preferably held in plap c' against displacement bya plate 60 ofsheet iron or steel, set into a recess in'the back of the mold section 14. This plate, when the m'oldis in position [see 8), abuts against the flanges 17 or the radial supports or plates l6 and is securely held in place. Where the moltedmetal comes in contact with these/ inserts it is verymuch less chilled thagyivhere it comes in contact with the iron surfaces of the mold. "By a suitable arrangementof the non-chilling inserts 59, such for example shown in Fig. 6, a brake shoe is made w 'ch will present a wearing face made up of ehilled'and non-chilled portions. I

It should be noted that the pouring trough upper sections of the are all formed at parting nes of the mold sectionsso that they open and; close with the sections and rapidly clear themselves of molten metal. In. this way. they will not be- I come clogged by chilled metal and, if. they do, can be reacily cleared. It should be further noted. that the mmable mold sections open outwardly or away from the center of the movablh frame or carrier, so that the upper portions of the movable mold sections may-be arranged to abut to form the pouring trough 46 when the sections of the moldare closed. If the movable mo'ld sections op enedinwardly they could not be provided with portions arranged to abut when shown asparticularly designed for the manug iacture of brake shoes, that it may be employed for casting other articles and that numerous modifications may be made in the details Tse't forth-without departure from the essentials ofthe invention.
