MACHINE FOR CASTING COLUMN RULES.

Application filed November 27, 1920. Serial No. 426,707.

Teal/Z whom it may concern:

Be it known that I, HARRY C. GAMMETER, a citizen. of the United tatcs, residing at Cleveland Heights, in the county of -Cuya hoga and State of Uhio, have invented a certain new and useful Emprorement. in Machines for Casting Column Rules, of which the following is a full, clear, and

exact description, reference 'beinghad to.

the accompanying drawings.

This invention relates to metal casting machines,and particularly to such machines which are adapted to cast column rules such as aroused in printing machine's.

One of the specific objects of the invention is to provide a machine in which curved articles such as columnrules may be cast.

An additional object of the invention is to provide a casting machine having certain of' 1 the mold members fixed and others movable, and wherein the movable membersserve to open the mold and e ect the casting.

Another object of the invention is to pro-v vide means for gripping a casting which has been ejected from the mold cavity, and for moving the grippedcasting1 A further object of the invention is to provide suitable means to cast a column drawings wherein Fig. 1 is a top plan view of a casting machine constructed according to my invention; F 1g. 2 1S aside elevation;

Fig. 15 is asection taken on two lines, the

portion to the left of A being on line 7'7, Fig. 3, and to the portion on the right on line 15 15 same figure. Fig. 16 is an ele-, vation of the casting end of the machine.

Referring to the drawing by reference characters, I have shownat 10 a standard, having a table 11 at its upper end. Carried on the tablel have shown-a pair .of spacedbrackets 12, which are adapted to carry suitable bearings for a shaft '14. This shaft 1% may be driven by a belt 17 on astep a jack shaft carrying the gear 16 which meshes with the pinion 15 tight on the shaft change of speed may be obtained. Such devices are well known in the art and will pulley 13 belted to a pulley 19 splined on i '14. By shifting the pulley, 19 and belting it to another portion of the pulley 13 a not be further described here, it being. sufticlent to state that the shaft 14; is to be driven at itsproper effective speedprovide means for operating the device'- slowly I may provide suitable means-shown a hand wheel 18, mounted on one end of;

the shaft 14-. v

Carried on the table; adjacentthe brackets 12 I may provide legs 20, which.

are adapted to support a, metal potx-21,

which is shown as provided with suitable heating means 22, such as a gas burner,

which serves *to maintain the contained pot 21 is shown in detail in Fig.11, wherein the basin adapted to contain the molten metal isprovided with a. port 25 communie metal at the proper temperature. The metal I eating with a chamber-26 in the wall of the basin. This chamber 26 is shown as cominun'icatingwith a nozzle 27 whichmay be V a cup like member having an aperture 28 therein. The aperture of-the nozzle 27 is adapted to align with the matrix as will be presently described.

In order that the supply of metal to the nozzle 27 may be properly regulated, I may provide a valve comprising a stem 30, having thereon a pointed end 31 which is adapted in one position to close the aperture 28 in the nozzle. The stem is also provided. with a closure for the port 25, which closure may comprise a coned member 35, as shown. The valve stem may be suitably supported adjacent the aperture and also have bearing ina lug 36 carried on a protuberance 37 on the basin. 2

I have shown a chamber 38' in the protuberance 37, which chamber is in communication thru a channel 39 with. the valve chamber 26. The upper end of the chamber 38.is adapted to receive a plunger or piston 40. shown as a cylindrical member having a pair of spaced collars 41 thereon. This plunger may be normally urged upwardly by means, such as a spring 42, carried on a bracket 44 on the pot 21. This bracket also provides. a bearing'for the upper end of the plunger 40. 2 To afford proper motion for the plunger 40, I have shown the shaft 14 as provided with a cam which is adapted to co-operate with a cam roller 51, the latter being carried on a lever '52, shown as pivoted at 53, on one of the legs 20 (Fig. 9). The lever 52 may be. provided with a pair of spaced lugs 54, which areadapted to receive between them a link 55, which may comprise. a pair of threaded

members

56 and 57. Pivoted to the rod 57, as at 58, I have shown a rocker arm 59, fulcrumed. intermediate its ends. at 60 to the pot 21, which is adapted to be secured at its other end to the plunger 40.

In order that reciprocating motion may be given to the valve member 30 I may provide on the shaft 14 a suitable cam 65, hav- 7 ing a cam surface 66 thereon, which is adaptedto coact with a roller 68, shown as carried by a bell crank 70. The bell crank 70 is shown as pivoted at 72 to a leg 20 of the metal pot 21 (Fig. 10). 'The arm 7 4 of'the bellv crank 70 may be adjustably connected at 7 5 with one end of a lever 7 6 which is shown as fulcrumed at 7 8 to the pot 21. The other end of the lever 7 6 is attached to a rod carrie on the valve member 30. The operation of ejecting a charge of'molten metal from the nozzle will now be described. We will assume that the partsare in the position shown inFig. 11; the plunger is beginning its downward motion. and the valve stem is at rest, and that the cavity 26, chamber 38 and connecting channel 39 are filled with molten metal. The shaft 14 rotates the cams 50 and 65 to give motion to passes thru the port and into the chamber This done, the valve stem moves to close the port 25, after which the operation .is repeated.

Carried on the table 11, I have shown a pairof lugs 100 adapted to receive arod 101, the latter being adapted to pivotally mount a supporting frame 102, which may be a casting. This frame 102 is shown as having a pair of spaced arms 104 near its upper end, which are adapted. to receive an axle 105. A table 106 is mounted on the axle 105. i This table comprises the horizontal portion 107 stepped up at 108, and from this latter portion a vertical back portion- 7 109 extends. I have shown a flanged curved plate 110 secured to the horizontal portion 107 and to the back 109 of the table by screws 113. This plate may be-provided at one end with a verticallmember 111. A pair of

guide plates

112 and 114 are secured upon the face of the vertical member 111 by means of screws 77. The vertical member andv the plates before mentioned have a rectangular upper portion 79 as shown in Fig. 8, while the lower part thereof flares outwardly as at 79 heinner one. of the two platesis provided, as shown in Fig, 4, with a depression 118, which is adapted.v to receive a matrix slide 115, the latter being shown as provided with a lug 116, which engages a tapering gib 120. The slide thus has vertical movement between the

plates

112 and 114. The lower edge of the plates 112 and.1-14, the slide 115 and the lower face of the plate 111 are, all

curved to correspond to the curvature of the.

article to be cast. The matrix slide may f have a suitable cavity C in its lower face corresponding to the shape of the articleto be cast. In the drawings I have shown the cavity C as a character die adapted to make a column rule. I

The means for actuating theslide will now be described. A pair of spaced lugs 125 carried on the frame member102 are shown as provided with means to pivotally mount a Y-shaped link 126', the Y'of the link being 0 arranged to straddle the drive shaft 14. The 7 arms of the link 126 are provided with

cam rollers

127 and 128, which are adapted to coact with cami surfaces mounted on the drive shaft 14. One'of the arms of the Y-meinber 132 extends beyond the other and is slotted as shown 317-133 for 129 and 130v a purpose to be later described. Mounted on the vertical member 111 I show a bracket 140 and pivoted thereon at 141 is a bell crank 143, one end of which has slidable engagement with the slot in the arm 132. The other end of the bell crank may be provided. with suitable adjustable bearing 144 for a projection 146 carried by the slide 116.

It will thus be seen from Fig. 2that as the drive shaft 14 rotates the cams 129 and 130, the link 126 will have movement about its pivot and will rock'the lower arm 143 of the bell crank tov the right and left, thus causing the upper arm of the bell crank to have an up and down motion and conse quently causing the slide 115 to have a similar motion,

The inner plate 114 be provided adj acent the lower end thereof with a channel 150, the latter corresponding in outline to, and being arranged adjacent, the, lower end of the slide 115. This channel is adapted to have communication thru hose members 155 and 156 (see Fig. 16) with a source of water, whereby the plate 114. the slide, and adjacent portions may be cooled.

Between a portion of the table 106 and the curvct plate 110, I slidably mount a curved plate 160, which is shown as held in place by gibs 161162, which may be prevented from moving by a set screw 163. The plate 160 in one position extends beneath the slide 116.

In order that reciprocating movement may be given to the curved plate, I may provide a suitable bell crank 170, (see Fig. 8)'

shown as pivoted to the horizontal portion of the table 108, at 171. On end of the bell crankmay carry an eye bolt 172 which is connected at its end to a, bar 173 on the slide 160. The connection may be adjustably made by a pair of coned washers and nuts 134. The portion 175 of the bell crank is shown as provided with a cam roller 176,

which is adapted to coact with the cam surface 177, the latter being shown as carried on a spur gear 178, driven thru a suitable mechanism, shown as a gear 179 driven thru bevel gear 180 (see Fig. 2) the latter being driven by second bevel gear 181 keyed on the main drive shaft 14. i

From the description it will be Seen that as the shaft 14 rotates, the plate 160 will be moved back and forth beneath the slide 115. The plate 110 may carry an L-shaped memher 183. which is adapted to have contact withthe projection 113 when the latter is at one extreme position. 7 Since the curvature of the upper face of the plate 160 corresponds to the curvature of the

plates

112, 114, and to the slide 116' these four members form a mouldingcavity. djacent the curved plate 160 I have shown a curved plate 196 which may be the frame by screws 99.

l have shown a plate 190 abutting the this recess a'block 202 is mounted.

'ecured to front face of the plate 160 (Fig. 7). I This plate is secured in position by a pair of rods 191, the ends of which are threaded, to re- 99 and bear against springs 1 7 (Fig. 7), the latter in turn bearing upon plungers198 which are connected thru'pins 199 with a gripper 200.

As will be noted the upper end of the block 190 is recessed as shown at 201, and in block may have a notch 203, forming a shoulder 204, adjacent its upper edge. The block 202 is adapted to move up and down and is normally urged upward by springs 205. The shoulder of the block 202 is adapted to engage the gripper 200 carried on the plunger 198, and thus be prevented from being moved upwardly by the springs.

To afford movement of the gripper 200, I may employ a trigger 207 pivoted at 208 to The bars 192 This a pair of lugs 209 carried by the slide 160.

The trigger is shown as having a tooth 210 at its upper end which coacts with a notch 211 in the grrppena spring 212 serves to normally urgethe top of the gripper toward the casting. The frame 196 is notched as at 230 (Fig. 14) to receive the lugs 209 and at A the base of thenotched portion 1 secure a bar 214 which may be held to the plate 196 by a screw 215. This bar may be provided with an adjustable stop member 216. The operation of the mechanism just described is as follows: W hen the slide 160 moves to the right of the position shown in Fig. 6, the

spring 212 acting thru the trigger serves to I hold the gripper against the casting. After the slide 116is elevated and as the l101'lZG11 tal. slide 160 moves to the left .in said figure it carries the trigger with it until thelower portion of the-latter engages the stop memrod and is normally held in this posiher 216, and causes the slide 200 to be moved tion by a bolt 220, pivoted at 221 to the upper portion of the mold supporting member. This bolt is adaptedto enter a slot 222, in a lug 223 on the pot 21. IA suitable nut 224 may be used to firmly hold the parts in position. r I

'VVhen, for any purpose, it is desired to have access to thenozzle of the metal pot, or to the parts comprising the mold cavity, or for other purposes, the nut 224 is removed, after which the entire table 106 and the parts upon it are swung upon the rod; 105. As this is done the projection on the] best shown in Fig. 8. Upon the gear wheel 179 I provide a tooth 227 which is adapted, during each revolution of the gears, to fit the notch 226. In order that the parts may be properlypositioned when the casting mechanism is returned to operative position it is only necessary to see that the tooth 227 fits the notch 226 and thus all danger of improper synchronism is obviated.

F lhe operation of the device is as follows Assuming that the parts are in the position shown in Fig. 2 and that the .mold cavity is empty, movement of the plunger -l causes a charge of material to be ejected into the mold cavity C. The hot metal runs down a cavity C, which is closed at its extremity by the plate 230, the plunger is adjusted to cause the proper amount of material, to form a column rule to be ejected, and, as soon as this amount is discharged, the valve closes, the plate 280 being yieldably held in position by the spring 230 to permit the escape of air from the molding chamber. As soon as this is done the lower sliding member 160 is moved to the right by the bell crank 170, lac-ting;

thru the gears 178, 179, in Fig. 6, until its front face aligns with the face of the plate 114;. As soon as this occurs the bell crank 14:8, operated thru the link 126, moves the slide 116 downward and this slide carries 'the cast column rule with it.

The plate 230 is swung about its pivot point 230 by the movement ot the slide 116, when the" slide is'moving downward. The column rule impinges on and depresses the e ector 202; The e ector being depressed a suiticient amount to clear the shoulder on the gripper 200. the latter moves to gripping position. his is shown in Fig. 6, where itwill. be noted that the casting is gripped between the face of the mold member. and he'gripper. As soon as the gripper has become operative the plate 116 is elevated,

leaving the casting held by the gripper. The lower mold plate now moves to the left carrying the casting with it. The spring pressure exerted on the gripper 200 is suilicient to prevent the casting from being pulled upward between the slide and the mold member 160. After the mold member 160 is moved to the'le'ft a sufficient distance the trigger 207, which. has engage ment withthe gripper, strikes the adjustable member 216 which causes the trigger to move the gripper from operative position. This done the'ejector 202 is forced up by the spring 205 and the casting is consequently thrown out. another charge 01" metal is forced into the mold cavity and. the operation repeated. Water circulating thru the channel 150 serves to keep the parts at the proper temperature.
