CASTING APPARATUS.

Application filed May 4, 1916.

2' '0 all iii/101R iii mflfl/COhCGTn .Be it known that 1, JOHN in-son BROWN, Jr., a citizen of the Unit-edStates,xresiding in Philadelphia, Pennsyivania, have in vented certain Improvements in (lasting Apparatus, of which the following a specification.

My invention relates to certain details of construction not claimed in a companion and copending application filed January 8, 1910, Serial No. 537,076, (patented May 21, 1912, No. 1,027,316),

The main object of the present invention is to provide means for applying weights to the molds of a casting machine.

A further object of the invention is to so construct the mechanism that the weights Will be removed from the molds prior to the flasks. I

The invention relates further to details of construction of the mechanism, as will be fully described hereafter, reference'heing had to the accompanying drawings, in which Y Figure 1, is a diagrammatic sectional view of a continuous casting apparatus, such as illustrated in the above mentioned patent, showing my improvement 2, is 11 diais a diiigranimatic pers 7Ct.i\-L-; view illustrating the location ofthe endless chain t flask rings with the supporting conveyor and en endless chain of fiask weights; Fig. t, is a view in elevation of one end of the casting appa ratus, snowing the means ror applying the weights to the flasks; Fig. 4*, is a similar view of the opposite end of the apparatus. showing the means of removing the weights from the flasks; Fig. 5, on end View looking in the direction of the nrrow C, Fig. 4;

with wheels 6 which travel on rails l, shown clearly in Figs. 8 and 9. These trucks travel only in a. vertical plane and in the direction indicated by the arrow, Fig. 1, and the sole object of this conveyor is to-support the flasks when filled with sand and during the process of casting.

8 ise horizontal conveyor, one run ofwhich travels. over the vertically arranged conveyor 1. These two conveyers are driven at the same speed and travel in unison. The horizontal conveyor 8 is made up of a series of flask carrying rings 9, Fig 11, connected together at one edge by links 10; the links being free to swivel, as clearly indicated in said Fig. ll, so that-tl1'ey will readily pass around the curves ateich end and will no coinniodetethemselves to any unevenness in the supporting tracks. The flask carrying rings do not not until after the mold is poured and r the bottom board is dropped prior to the discharge of the send and castings, then the flask drops onto the carrying ring and is sup tiorted by said ring until its return to the molding machine. 7

The conveyor 1 passes around sprocket wheels 11 and 12; 11 in the present instance l-cing the driving wheel; and the conveyor 8 g asses around sprocket wheels 13 and 14, and 13 in this instance is the driving wheel. The two driving wheels may be connected I together in any suitable manner so that the two conveyers will travel together in unison. The flask 15, illustrated in Fig. 14., 18

made .with the cope 1(3 and drag 17, and

rest directly above the rings but clear of the rings when the flasks are carried by the trucks 2, but as soon as the truck is moved away then the flasks drop and the lugs 21 rest directly upon the rings 9.

The rings J of the horizontal conveyor have wheels which travel on rails 23, as shown in Figs. 8 and 9. These rails are in the form of angles and the upright portions of the angle rails act as guides to hold the rings laterally in osition and on each end of each ring, as illustrated in Fig. 11, are wheels 24, which rest against the rails 23.

25 is the molding machine which, in the present instance, is within the loop of the conveyor 8 and located at one end of the apparatus, This molding machine may be of any construction desired. The flasks are tilled by the use of this molding machine and placed in the rings to he carried to the pouring point. In fact, in some instances, the molds may be made by hand, if desired, without departing from the essential features of the invention.

inorder to properly hold the sand within the mold during the pouring operation, I pro ide weights 26 which rest directly upon the sand of the mold, and in each weight is an opening 2? directly in line with the pouring opening of the mold, so that when the conveyer reaches the ladle 20 arid is stopped, the opening in the Weight and the pouring opening will aline with the mouth of the ladle, so that the metal can be properly poured into the mold. The weight prevents the upward displacement of the sand dur' ing the pouring operation, insuring accurasy in the castings.

n order to properly place the weights on the mold, I connect them together, forming an endless chain of weights 26, which pass around a driven sprocket wheel 29. At the opposite end is a guide 30 around which the enchained weights pass.

31, 31 are guide rails for supporting the weights after they pass over the center of the sprocket wheel 29 and on the outside of each of these rails and running parallel with them for a certain distance are rails 32, and it will he noticed, in referring to Figs. 7 and 10, that each weight is carried by axles 33 and 34, and on the rear axle 33 are single grooved wheels 35 which tra el only on the rails 31, whereas on the forward axles 34 are double grooved wheels 36 which travel on both rails 31 and 32. The axles are connected together by loose links 37. The links in the present instance are arranged in sets of three, so that the weights will independently accommodate themselves to the rails and to the flasks and, when the weights rest upon the sand within the flasks, there is no tendency of the weights to move, as any movement of the weig ts would be liable to destroy the molds.

it will he noticed that the rails 31 and 32 are so arranged that when the point 00, Fig. 41* is reached the weights begin to travel in aline parallel with the flask, the rail 32- lifting the forward end of the weight owing to the fact that the wheels 36 travel on the rails 32 and are oi the rails 31. From the point a: to the point y the weights gradually settle upon the sand and when the weights contact with the sand, as at 1 they are carried by the sand and not hy the wheels, so that there is no disturbing of the sand of the mold as the weights are applied to the sand. This is essential, as it will be understood that the elements of the apparatus are moving intermittently in unison and any disturbing of the sand will be liable to ruin the mold.

It will be noticed that, when the weights are on the sand of the flasks, the weights are loosely connected one with the other and the links drop a trifle out of line, as illustrated at a, Fig. l. This slack is taken up again as soon as the weight leaves the flask on the return run, due to the fact that the pitch of the sprocket wheel 29 is greater than the pitch of either of the sprocket wheels 11 or 13.

The rails 31 connect with the rails 37 of the guide 30, as illustrated in Fig. 4 and running parallel with this rail for a certain distance is a rail 38 which connects with a supporting rail'39 for supporting the return run of the weights, Fig. 1. i

In order to prevent accidents due to the overpouring of the metal in the mold when the weight is parted from the flask, I provide anelect-ric knife switch 40 having an arm 41, which is located directly under the traveling weights, so that any projection hanging from the weights would strike the switch and throw it out of the contacts 42, and, as this switch is connected electrically with the power mechanism of the entire apparatus, it would immediately out off the power and stop the entire mechanism, as in some instances the metal may overflow to such an extent as to connect the sprue with the n eight, and, consequently, when the weight is lifted oil the mold, it would simply pull the casting out of the sand hut this casting would strike the arm 41, above described, andwould immediately. stop the mechine before any damage was incurred.
