Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed September 23, 1910. Serial No. 583,415.

To all whom it'may concern:

l3e it known that 1,.JQHN T. S'roNEr, a 011312811 of the United States, residing at Cleveland, in the county of Guyahoga and State of Oh o, have mventeda certain ne\v use of a stripping plate.-

" "Reference should be had to the acc'om--' panying' drawingsforming a part' of this drawn.

application in which Figure 1 is'a top plan view of the molding machine; Fig. 2 is a side elevation with certain parts in section; Fig.3 is an end machine with the top .portion removed; Fig. 5 is an endelevation' of the showing in Fig. 4:; Fig. 6 is a side elevation of the machine in position -to jar the mold; and 'Fig. 7 is a side elevation of the machine in position just after the patterns have been The base 1 is provide'd'wit-h end pieces 2 which support upright side pieces?) and 4.

These side pieces assume the general shape shown in Fig. -3, although other shapes may be employed with-equal facility. Upon-the base 1 an anvil 5"i"s supported which is for the purpose of receiving the impact when the platform carrying the moldis allowed .to drop. This anvil "may'be 'form'ed inte- .gral with the base, as shown, or if desired,

} maybe separately constructed and attached thereto. The anvil 5'is provided-with a central opening through which extends a fluid pressure cylinder 6, and this cylinder 15 secured to the anvil 5 in any desired manner,- one form being. shown in Fig. 2. A sliding eelrmember 7 surroundstheoylinder and 'is'prowith the flange 8 at the low r. end

thereof, which normally rests upon the an v11 5. It will be understood that the cylinder 6 and the sliding member 7 are fitted to each other so as to permit an easy slide between the members and yet not allow'any loose play. i y

The cylinder 6 is provided with a packmg rmg 9 near the upper end thereofiwhich is for the purpose of preventing the escape of air through such space as may exist between the cylinder and the sliding member. Near the lower end of this cylinder a port 10 is provided which is connected with a suitable source of fluid under pressure by niezirlis of a flexible tube, such as indicated a mission of fluid to the cylinder form no part of this invention, and as forms of valves suitable for this purpose are common, further description is not believed to be necessary. The cylinder fi is -also provided With exhaust ports 'l2'which are situatedit short distanoe'above the lower endfIof-th'e cylinder, and these ports are normally kept closed by the sliding member 7. Then, however, the sliding member 7' is raised due to the admission of a fluid within the cylinder, to such a point so as to uncover the ports 12, then the fluid within the cylinder will be permitted to pass out of the ports 12 which will'in turn destroy it-he pressure which has heretofore held the .sliding memher in elevated position, and the sliding member will thereby be permitted to drop of its own gravity and impact against the anvil 5. As'soon as the sliding member has reached its lowest position, the fluid which is still {being admitted through'the port-10 will'againcreate a pressur'e to' raise tjhe'sliding member 7, and again the fluid-will be permitted to'exhaust through'the ports l2.

The admission :'port 10 and the-outlet ports 12 are so arranged that this up and down movement of the sliding member 7 takes place with-great rapidity and amounts to a vibration.

At its upper end, the member 7 supports a platform 13 which is connected with .or integral. with the sliding member 7. This pl'atforniextends to the side pieces?) and 4.

.To the ends of the platform 13, rods are fixed, one of which'is'shown at 14, and doat its lower end'is provided with an ad; j'ustable collar 15 for a purpose to be la described.

wpends through the end member 3. This rod In the upper end of the cylinderfi is a cup shaped piston 16 which is of slightly larger external diameter than the internal 1 diameter of the cylinder, the cylinder 6 bea close but working fit.

ing sufficiently enlarged at that portion where the member 16 is placed, to provide an opening to accommodate the pistonwith The piston rests upon shoulders 17 which are formed in the interior surface of the cylinder. -When the fluid is admitted to the port and creates a pressure within the interior of the cylinder, the piston 16 is raised and contacts with the platform 13, which, as before described, is either integral or attached to the sliding member 7, and thereby the platform is raised.

For the purpose of raising the platform and holding the same without vibratory movement, a port 18 is provided inthe sliding member 7, and this port is connected extends. As before stated, this member 15'- is adjustable so that the extent of movement of the platform 13 may be regulated. The fluid control for this portion of the machine will be arranged with a valve which when turned in certain directions will permit the air to exhaust from this portion of the machine through the same tube 19..

At the end portions of the platform 13 are uprights 20 and 21, the same being s cured to the platform in any, suitable manner. Attheir upper ends, these uprights are formed with journals which accommo

date stub shafts

22 and 23, each of which shafts is provided with an arm 24 and. 24

that supports a platform 24. Through the upright 21 there extends a pin 25, which cooperates with a depression 26 formed in the stub shaft 23 to hold the platform 24 from swinging. provided with a depression 27 arranged upon the shaft directly opposite the-depression 26 and is for the purpose of holding the platform from movement. when the same is swung to its upper position, as in dicated in Fig. 3. A plate 28 which carries the patterns 29 is supported upon the platform 24 in any desired manner and this plate is provided with plates 30, to which are removably secured clamping members 31, as indicated in Figs. 2 and 3. The flask is p a ed p n the plate 28 and the clamp This shaft 26 is likewise ing members; are arranged tohold the flask upon the plate, as indicated in Fig. 3.

When the flask is 'first placed upon the plate 28, themachine vand its parts occupy the positionsubstantially as shown in Fig.-

2. The sand is then placed within the flask and the fluid is admitted'through the port l0,-and exhausted through the ports 12, in a manner as heretofore explained, which vibration causes the sand to pack around the patterns and the mold is thus formed. When the mold isxcompletely "formed, a' board is placed over the-top of the mold, as indicated at32, in Fig. 3, and-is held in place by the clamps. The mold is then raised and the pin 25 is withdrawn; the platform 24 is-rolled over and-the pin 25 allowed to seat itself in the openin 27 in the shaft 26, whereby the mold will e held in its inverted position, as shown in'Fig. 3.

The mold is next lowered until the flask rests upon the

sides

3 and 4. The clamps 31 may then be released and the air ad mitted through the pipe 19 to the upper side of the piston 16, whereupon the plat form 24 and the patterns will be raised away from the mold. The mold may then be withdrawn; the platform 24 returnedto its original position, and the operation again repeated.

, For certain operations, it may be de sirable to dispense with the turning over mechanism, and when such is the case, the

uprights

20 and 21 are removed, together with all the mechanism which they carry. The patterns 29 and the plate 28 to which they are secured are then mounted upon the platform 13 but. are usually shimmed up from this platform by means of a block, such' as shown at 32, for the purpose of providing clearance, as will be hereinafter described. In such a construction, patterns, together with the plate 28. to which they are secured, form a part which is movable with the platform 13. The

end pieces

3 and 4 are connected by side pieces 3- and 4 which members upon their inner sides are formed with ribs 33. Sliding members 34 and 35 are provided in their ends with slots which are of proper size to cooperate with the flanges 33, and these members are adapted to slide so that they may be moved from the center to the ends of themachine. The flask will be secured upon the plate 28 in the same manner as heretofore indicated,.'120

and will be filled with sand and vibrated in the manner heretofore explained. After the mold is completed, the platform 13 will be raised by admitting air to the port 18- and then the members 34 and 35 will he slid" in;

wardly from the ends until they underlie the edges of the flask, whereupon the clamps will be removed and the platform 13 re turned to its original position. In this manner, the patterns Will be removed fromr w weaves the mold and thereafter the mold may itself be taken away.
