To all whom it may concern Be it known that we, ALEXANDER ROBERT- -soN, LUTHE S RESSER, and LHAnnY E.

WHEELER, citizens of the United States,

all residing'at Alliance, in'the county of Stark and; State of Ohio, havejointly 1n- .vented certainv new and useful Improvements in Flask Shake Outs,-'of which the relates to Shaking the sand out of foundry 'Lflasks.

following is a specification. The present invention relates to flask shakeouts.

More particularly shaking means the present invention suitable for Shakers for this p'urposehave been provided in the past but'are open to objections various reasons, among which it may noted that certain prior .shakers havein- 'volved handling of relatively heavy parts.

An object of the present invention s to provide a flask shakeout which may be stationarily mounted, which occupies a m n mum of space in a .shop,'and which simplifies the matter of'applyin'g a flask thereto and removing said flaskthe'refrom' A further object is. to provide. a; flask shakeou't of simple construction which'will be very eflicient in service.

' A further object is to provide a flask shakeout which cushionsthe shock relative -to the foundation but permits a very efli- 'cient shaking of the flask or other device I being treated.

dicated by the" arrows 1'-1 of Figure 2;

Figure 2 is a top plan ,view of thestructure shown in Figure 1; and

Figure 3 is a-sectional view taken along the plane indicated by the arrows 3-3 of Figure 2.

The numerals 11 indicate frame mem bars, which may take the form of I-beams. Said frame members may be supported by any suitable foundation, as indicated by the numerals -22, which should permit ready access to the region beneath the frame-members l.1. Connected between the i frame which mayf'be riveted to the frame; memmembers 1- 1-are the-two cross ties 3--3,

bers 1'1.. to provide a sturdy structure." 7 Mounted upon the cross ties 3-+3 are a .plu-

rality of brackets 4.- l providedjwith upstanding pms 55 Said pins '5 5 are preferably located at; the four corners of a rectangle and serve as supportin'g mem I bersfor the springs 66,.

The numerals .7-7' indicate bars, each having head portions 88.at its two ends, :which head portions are provided "with recesses 9'9 for receiving the upper extremities of the pins 5- 5. Said bars 7-j- 7 rest upon the' upper extremities of the springs 6-6, the lower extremities of said springs 66"seating upon outstanding portions of.

the I brackets Each of the bars 77 has an enlarged portion 10 intermediate of its length, which enlarged portions provide housings for vibrators 11. {The details of the vibrators do not constitute the present invention and need not be disclosed in detail inasmuch as .vibrators suitable for the purpose may be" purchased ,in the open market. It may be stated briefly, however, that each vibrator includes a plunger 12 housed within a cylinder 13, which cylinder 13 is held within 5 the enlarged portion 10 by any preferred mean-s. Straps 14-'14 are indicated for this purpose, which straps may be bolted orriveted to the bars 7-7., 'Each of the cylinders 13-13 is'provided at its ends with a hardened steel plate 15 for receiving the blow 'of 'the'corresponding plunger 12. Each of the vibrators 11 is provided with" an air inlet '16, it being understood that the pressure-of the air'is controlled in any preferred way. (not illustrated) for causing the plunger-- 12 to have a rapid reciprocatory movement; whereby to strike hammer blows against-the plates 15 -15.] The bars77 present a horizontal surface 4 upon which the flask 17 may be placed.

'It will be clear that a violent shaking 'motion can be transmitted to said bars by the rapid hammer blows struck by the lunger 12 against the plates 15-15 in the vibrators v11. The violent shaking of the barsf-77 is communicated directly to the flask 17, the'efl'ect of this shaking being the more marked by reason of the fact that the bars -77 A are resiliently mounted upon the springs 6-6. A dancing motion is communicated toxthe flask, causing the sand to shake out more effectively than if the springs 6 are not provideds Not only isthe advantage attained that the sand is shaken out more eflecti-vely, but the further advantage is attained that, ,due to the cushioned mountstroke.

means carried by -means adapted to communicate 'a blow to ing Ot-the Tbars 7*.7, the framemembers 1'-1 are protected against the violent shaking communicated to "the bars 77. The matter of maintaining fonndations is there fore greatly simplified. ,I

-Inasmuch as the 'shdkeout illustrated is mounted upon a permanent foundatiomand i nasmuch as there is no necessity for lifting said shakeout; it isnot necessary tq-provide a crane for lifting an )artof.sai'dshakeoutf" e yl Lifting means need be provided of only suflicient' size to handle the flasks.

Though a preferred embodiment of ,th present-invention has been described in detail, it will be clear that many modifications will occur to 'tlTose' 'skilled in the art. Itis intended to cover all 'within the scope of the appended claims. We claim:

I 1. A flask shakeoufizomprising relatively carrying rigid supporting means, [flask means, resilient means between said supporting means and said flask carrying means, and reciprocatingblow communicating said flask. carrying said flask carrying means at each end of its 2. A flask-shakeout comprising supporting -me ans, a flask supporting member, resilient means between said supportmg'means and said member, a cylin er carried by said member,

' said cylinder adapted tocommunicate a stroke.

ties between said supporting members,

modifications falling of spaced bars,

and a reciprocableplunger within said member at each end of its- 3. A'flask shakeout including a pair of "spaced supporting members, a pair of cross upstanding pins carried by said cross ties, springs upon said pins, and a pair of spaced bars having recesses adjacent to their ends fol-receiving"said pins, said bars being supported by said sprlngs,

said bars being provided intermediate of their length with vibra'iory means for communicating hammer blows to said bars", ing a 'substamtially for receivinga member to be shaken.

5. A flask shakeout comprising a relativesaid spaced bars presently stationary supporting member, a flask supporting member, resilient means for sup.

porting said latter mentio'riedmember o'n horizontal upper surface said first mentioned member, and blow communicating means housed within said flask supporting member and adapted to, communi'cate a blOWr to said flask supporting member at each end of its stroke.. v

6. A flaskshakeout 'includinga pair of spaced supporting members, a pan ofcross ties between said supporting members, a pair resilient means between said spaced bars and said 'cross ties, said bars being provided intermediate with vib atory means for communicatnig hammer b ows'to said bars.
