Specification of Letters Patent.

Patented Aug. 8, 1911.

Application filed May 6, 1903. Serial No. 155,869.

To all whom it' may concern.'

Be it known that I, CHARLES MILLS, a citi- Zen of the United States, residing at Newton Upper Falls, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Molding-Machines, of which the following is a specification.

My invention relates to molding machines and has for its object to provide a new and improved machine of this description.

My invention is illustrated in the accompanying drawings, wherein- Figure l is an end view of a machine embodying my invention showing the pattern in outline and the flask broken away; Fig. 2 is a side view of the same the pattern and flask being omitted; Fig. 3 is a section on line 3 3, Fig. 2; Fig. l is a section on line 4 4, Fig. 2; Fig. 5 is a section on line 5-5, Fig. 2; Fig. 6 is a vertical sectional view through the stripping plate, flask and pattern.

Like letters refer to like parts throughout the several gures;

Referring now to the drawings, wherein I have shown one form of my invention, I provide two side pieces A and B, each of a single piece and extending from the stripping plate C to the floor. Between the side pieces and rigidly attached thereto is a stationary piece or frame D, upon which is mounted the shaft D1. This part D may be connected to the side pieces A and B in any desired way, as by means of the bolts D2. The side pieces A and B are connected at the bottom by means of the rods or bolts A1. These rods are supplied with screwthreads and adjusting nuts, so that the position of the side pieces may be adjusted. These side pieces and the piece D and the rods A1 form what may be termed the main frame of the machine. The side pieces A and B are provided on their inner faces with guides A2 and B2 (see Fig. 2), which project therefrom and form guide-ways on the side pieces. Within the main frame is a movable or sliding frame, consisting of the bottom frame G, the pattern plate E, the pattern plate supporting pieces El and the rods F attached to the pattern plate supporting pieces at one end and adjustably attached to the bottom frame G at the other end. The pattern plate supporting pieces support the pattern plate and are provided with guides E2, which engage the guideways in the side pieces of the main frame (see Fig. 5). This bottom frame G is provided with holes at the corners, through which the rods F pass, and is provided with guides G1, which coperate with the guideways on the side pieces A and B formed by the projections A2 and B2. The shaft D1 is provided with two cranks G4, one near each side of the main frame, and a pin Gs extends through these two cranks connecting them together. A shaft G2 is mounted in the bottom frame G and a connecting piece G3 has one end `connected to said shaft and the other to the cranks G2, said connecting piece filling the space between the two cranks. This construction gives a gearing which occupies substantially the wholevof the space between the sides of the frame, and thus provides extended bearing surfaces to take up the Ythrust or shock produced by ramming the sand in the flask. The rods F are each adjustably connected to the bottom frame G in any desired manner, so that said frame may be moved up and down therealong to secure the correct adjustment of t-he height of the movable frame in the construction and assembling of the machine and for taking up the wear which may occur in the use of the machine. By means of these rods, each of the corners of the inner frame are separately adjustable, rendering it possible to easily build a machine which will be absolutely accurate. One machine may be adapted for draws of various lengths by simply changing the height of the main frame piece D and the length of the cranks G4 in a corresponding manner.

The stool plate D3 is connected to the stationary frame piece D and is formed so as not to interfere with the movement of the movable inner frame, t-he sliding pattern plate rails passing by the stool plate in descending. This stool plate acts to support any stools that may be necessary when a pattern requiring stools is used.

The guides A2 and B2 and the inner faces of the side pieces A and B are finished throughout their entire length, so that the main frame piece D may be raised or lowered in adjusting the machine to adapt it to the conditions presented, or the movable frame drawn, and yet be provided with proper guide-ways and locating parts.

In Fig. l I have shown a simple form of pattern E4 in position on the pattern plate E, and a stool supported on the stool plate D3. It is of course evident that any desired form of pattern can be used, and I have shown a simple form for purposes of illustration. In Fig. 6 I have shown the parts in position, including the flask EG.

In assembling the machine, the side pieces A and B are set up and fastened together by the rods A1 and the main frame piece D. The inner frame is then assembled and placed in position and connected with the main frai'ne by the connecting piece and the parts adjusted in the desired manner.

It will be noted that the upper and lower ends of the movable inner frame are provided at each corner with guides, which engage the guides on the main frame and that the adjustable rods F passing through holes in the stationary part D form additional intermediate guides between said upper and lower guides. The guides A2 and B2 at each. corner are preferably made integral with said frame and extend substantially along the entire length thereof and in addition to serving as guideways top and bottom for the movable inner frame act also as surfaces for accurately locating the parts of the stationary frame.

In the operation of the device the parts are moved so that the pattern plate is in the position illustrated in Fig. 2, that is, up close to the stripping plate. The flask is then placed in position and the sand rammed about the pattern. The pattern is then withdrawn from the flask by the operator moving the handle, so as to rotate the shaft D1. This shaft, through the agency of the cranks G, the connecting piece G3, and the shaft G2, moves the pattern plate and pattern downwardly, as the shaft G2 is connected with the bottom frame piece G fastened to the pattern plate frame. The pattern is then withdrawn from the flask.

By means of this construction, I am enabled to provide a simple, rigid machine, having large and extended bearing surfaces for all movable parts, which may be quickly and easily and accurately adjusted, and a machine that may be easily manufactured and easily assembled. It will further be noted that this machine will take a long stool plate.

I have described in detail a particular construction embodying my invention, but it is of course evident that tlie parts may be varied to suit varying conditions and such variations will readily suggest themselves to those versed in the art.

In the operation of the device the iiask is placed in position and the pattern plate moved up to its top position. The sand is then rammed into the flask. The shaft l)1 is then rotated so as to move the pattern,

pattern plate and associated parts to withdraw the pattern from the sand.

I claim:
