CHILL-MOLD APPARATUS.

SPECIFICATION forming part of Letters Patent No. 390,355, dated October 2, 1888.

Application filed February 18, 1888. Serial No. 261,481. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM FAWOELT, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Chill-Mold Apparatus for Casting Sash-\Veightaofwhich the following is a full, clear, and exact description.

My invention is an improvement in the class of apparatus for casting saslrweights or other articles in which the molds are chilled by water. In my apparatus the hollow sectional molds are arranged in a rotary frame about a hollow axle having water supply and exit pipes suitably attached.

The construction and combination of parts embodying the invention are as hereinafter described and claimed.

Reference is to be had to theaccompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the device. Fig. 2 is a front elevation. Fig. 3 is a vertical section on line at x of Fig. 2, and Fig. 4 is a vertical section on line 11g of Fig.

In carrying out the invention I provide a mold having a water chamber or jacket surrounding the impression bed or mold proper, as will be hereinafter more particularly described.

In further carrying out the invention two spaced disks, 10, are mounted upon a hollow shaft, 11, which disks are preferably provided with radial arms 12, corresponding in number to the number of molds 13 to be employed. The shaftll is divided centrally into two sections by a partition, 14, and each section is provided with aseries of circumferential aper tures,15,near the outer ends, two apertures be ing provided for each mold. The disks and shafts are preferably made integral, and the shaft is thickest outside the-disks Where the disk is apertured. The said shaft is journaled in any suitable standard, 16, and provided at one end with a gear, 17, driven from a mutilated gear, 18, as illustrated in Fig. 1.

The molds 13 are made in two preferably rectangular sections,19 and 20, containing any desired or convenient number of impressions 21. Each section is hollow and of a length greater than the length of the sashweight to phragm, 22, extending from the bottom to a point near the top, as shown in Figs. 3 and 4.

The section 20,0r that section which is lowest when the molds are to be poured, projects beyond the section 19. It is curved upwardly upon the under face, as shown at 23 in Fig. 3, the gate 21 being produced in the upper surface of the extension, adistance from the outer edge, whereby, in pouring, the ladle may be rested upon the shelf 25 so formed.

The sections of the molds are pivoted to the disks at opposite ends, the section 19 being pivoted to the arms 12 at the upper end and the section 20 at thelower end, whereby, when actuated, they will open in opposite directions and in parallel lines,as illustrated in the lower portion of Fig. 3.

A water-supply pipe, 26, is loosely entered into one end of the hollow shaft, and an exitpipe, 27, at the opposite end, the shaft being provided at each end with a suitable stuffing box, 28, as shown in Fig. 4.

From the various apertures in the shaft a pipe, 29,which is preferably tlexible,(but may be made in sections connected byjoints that allow the required mo vcment,) is projected upward through the shell and carried through a slot in the disk, one pipe upon each side, into each section of the molds upon opposite sides of the diaphragm. Thus as the molds are revolved a circulation of the water is. obtained around the impression, causing the casts to quickly cool.

Inorder to automatically open and close the molds at the proper time,circular plates 30 are pivoted to the sides of the device, one plate opposite each mold upon both sides. The plates 30 are provided with an eccentric-slot, 31, above and below the center, in which slot pins 32 and 33 respectively travel, one pin being integral with each section of the mold,and when said sections are closed the pins occupy corresponding positions in the slots, shown in Fig. 1.

The circular slotted plates 30 are each provided with a rod, 31, projecting from the pcriphery, and an arm, 35, integral with or attached to the outer side removed from said rod,which'arms, as shown in Fig. 1,cxtend beyond the periphery, preferably in a curved line.

At each side of the machine,adjarent to the forward ends of the supporting-standards,are lugs or blocks 36, having rearwardlyinclined faces, and from the rear of the standards, at about their centers, are inwardly-projecting horizontal bars 37, which are secured thereto or made integral therewith.

In operation the water is turned on and the shaft rotated with an intermittent motion. The said motion is obtained by means of the mutilated gear, which is so toothed that at each revolution of the same the teeth will engage thegear upon the shaft long enough only to move each mold a distance forward equal to about the distance intervening them at the outer ends. brought to an upwardly-inclined position,with the section 20 lowermost, the ladle is rested upon the lip thereof and the metal poured in. By this time the gears again engage and the filled mold passes downward with aslow movement, the next mold coming to position to be filled and stoppin The intermittent movement of the mold-carriers permits the circulating water to rapidly cool the casting and the molds, so that the metal is thoroughly chilled when cast and comparatively cool when delivered. Upon the continued movement of the filled mold the peripheral bars of the slotted plates engage the base blocks, whereupon the plates are partially revolved, and the mold-sections, by reason of the connection between them and. the plates, are separated and the castings allowed to drop through the aperture in the base into any suitable receptacle. Upon the upward passage of the mold the side arms of the slotted plates are brought into contact with the stops upon the standards, and the sections closed by said contact and the reverse revolution of the plates.

It is to be understood that I do not limit myself to the particular form of mold herein set forth, as the mold may be differently constructed and arranged without departing from the spirit of my invention.

Having thus described my inventiomwhat I. claim as new, and desire to secure by Letters Patent, :is-

1. The combination, with a rotary frame, of hollow sectional molds, one of the sections being pivoted at its outer end and the other at its inner end to said frame, water supply and exit pipes leading into said sections, a hollow When one of the molds has been shaft carrying said frame, and supply and exit pipes connecting with the shaft, substantially as described.

2. The combination, with a hollow axle divided into two compartments and having openings through its sides, and a frame secured to said axle, of hollow sectional molds, each section being oppositely pivoted to the frame,and one of the sections having a curved lip on its outer end, and water supply and exit pipes leading into said sections and communicating with side openings in the axle, substantially as described.

3. The combination, with a hollow axle divided into two compartments, a frame secured to said axle and hollow sectional molds pivoted in said frame, of water supply and exit pipes connecting with the compartments of the axle entering into and projecting from each mold-section and revolving with the shaft and molds, substantially as shown and described.

4. The combination, with a rotary frame, of hollow sectional molds pivoted in said frame, divided into connecting apartments, and water supply and exit pipes leading into and from the respective compartments of each section and revolving with the molds, substantially as shown and described.

5. The combination, with a revolving frame and sectional molds having each section oppo sitely pivoted in the frame, of plates pivoted upon the frame provided with eccentric-slots at opposite sides of the center, pins projecting from the mold-sections traveling in said slots, and means for alternately rocking the plates in adverse directions, as and for the purpose specified.

6. The combination, witha revolving frame, sectional hollow molds having each section oppositely pivoted upon the frame, water supply and exit pipes entering into and projecting from each section, and revolving therewith, of plates pivoted upon the frame provided with eccentric-slots at opposite sides of the center, pins projecting from the mold-sections traveling in said slots, and means, substantially as described, for alternately rocking the plates in adverse directions, substantially as and for the purposes specified.
