At u@ tween the front and back of the box, is a thetime ice is purchased it may be placed in .main lever, one ol" its ends being fulcrumed receptacle 22, as shown in Fig. 1, and its weight may be ascertained by reference to the index. The bottom of theI receptacle is provided with a drain pipe Q7, and water from melted ice may be discharged withinf pipe 28, these parts, however, being so disposed that pipe 27 will not' make contact with pipe 28 to interfere with the operation of weighing.

At 29 is indicated an angular' flange dis-l posed at the lower part and mounted up on the upright walls of receptacle 2Q, to provide a container or drain for the condensed moisture which may form on the outer sur tace of said walls, and the water from this source may pass into the receptacle through port e,

It will be noted that the receptacle 22 is normally disposed adjacent to the upright Walls of the boX, and may be conveniently removed and replaced, this being of advantage for sanitary reasons, and on account of the construction as described, a passageway it is provided which extends entirely around said receptacle to permit a 'ree circulation of air. tlso on account ot' the provision ot disk Q6 and its mounting, and the mounting of the secondary levers 25 thereon, the receptacle 2:2 is supported to advantage. It may haile'a slight vertical movement during the operation et weighing the ice, but it may 'notl have a sidewise swinging movement at any time.

Since attachments for weighing ice, as described, would be oit no practical-.advantage unless the weight thereof could be accurately determined, and since a continued strain of the spring would tend to injure or weaken it, means are provided tor preventing any strain or tension of the spring while the lid is closed. rthis may consist, in part, ot a cam 30 which may be mounted upon wall 7 by means of the pivot-pin 3l which is disposed below lever l2 adjacent to aperture llt. Mounted upon wall 7 is a rock lever 32. Upon one otlthe arms of the rock lever is pivotally mounted one end of a li-nk the opposite end of this link being pivotally mounted upon the cam. Upon the other arm of the rock lever is pivotally mounted one end of the link 3ft, its opposite end being pivotally mounted upon bracketl 85, said bracket being mounted upon the lid 10 of the ice boX. The parts are so arranged that when the lid is raised the cam may have a rotatable movement, substantially,'of 180 degrees so that it will not engage lever 12, and the weight of receptacle Q2 and its contents will cause said lever to swing downwardly in aperture 1i subject to the resistance of spring 20at which time said weight may be determined by the index a. A downward swinging movement of the lid, howev'er, will cause reverse movern'ents of the arms ot the rock lever, to that'last described, 4and the` rotatable movement of the cam will cause its periphery to engage lever 12 and will cause the lever to swing upwardly. '.lhe upward swinging movement of said lever will cause rod l5) to move upwardly to terminate the` tension of the spring, and. lever l2 will be in engagement with the cam at all times except when the lid is completely raised. Means are provided tending to prevent the lid from closing and to maintain it in an upright position until manually closed. For this purpose the pivotal mounting for the rock lever consists of the thumb screw 36 in engagement with said rock lever and with block 37, as best shown in Fig. l. By an adjustment ot the thumb screw a pressure ot said screw against the rock lever may be made sulticient in degree to prevent t-he lid from swinging downward from accidental causes, but the lid may be closed by manually grasping it and swinging it downwardly against the force of said pressure.

Means are provided for causing a closure of the aperture it of wall 7 within which lever l2 moves, to thereby prevent an undue `melting of ice. This aperture must be ol: ample size to permit the movements of' link 12 without binding or undue l'riction and a ,closure of'said aperture is therefore necessary. By reference to Fig. 3 it will be seen that the, operation of the rock lever 32 will. cause the cam to be disposed in its lowernost position when the lid l0 is raised, and the operationot these parts is such that when the lid is swung downward or closed, the cuni will be elevated to the position shown by the dotted, circular line; and 'by these means, which operate antonmiically, a closure will be made ot substantially all ot the area ot the aperture, except the space occu` pied by the lever, and this closure ot the aperture will continue while the lid l() remains closed.

lllhile I have described construction iu detail, it has been for the purpose ol clearly explaining one embodiment of the invention, and it will be understood that I may make certain changes in form, size, proportion and minor details, within. the scope of the appended claims.

l/Vhat I claim and desire to secure by lietters Patent is,-

'1. ln weighing attaclnncnts tor an ice box, the combination of a main lever disposed transversely of and fulcrumed in the box, a spring supported by the box and connected with said main lever; a disk provided with a projection and supported by the main lever; a plurality of secondary levers lulcrumcd in the box and supported by the disk, a recoptacle mounted on the secondary levers for 1.25

the tension of the spring.

for causing a tension of the spring; an index adapted to be actuated by a movement ofthe main lever; alcam mounted on the box; and an arrangement of links connected with the cam and said lid for moving the cam into engagement with the main lever by one of the movements of the lid for terminating 3. In combination with an ice box having an apertured wall and a movable lid, a main lever traversing the aperture of said wall. and fulcrumed in the box, as ring supported by the box and connecte with saldxnain lever; a receptacle supported by lsaid main 'lever for causing a tension of the spring; an index adapted to be actuated by p a movement of the main lever; a cam mounted on the box; an arrangement of links connected with the cam and said lid for causing a rotatable movement of the cam by a movement of the lid, the operation being that said movementof the cam will cause a closure of a part of said aperture and will cause a. movement of the main lever for terminating lthe tension of said spring. 4. vIn combination Wlth an ice box having an apertured Wall and a movable lid, a lever disposed in said aperture and fulcrumed in the box, a spring supported by the box and connected With the lever, a receptacle supported by the lever for causing a tension of the spring, and a cam adapted to be actuated by a movementof the lid for making a closure of a part of the aperture of said wall and for terminating the tension of the spring.

In testimony whereof I have affixed my signature in presence of tvvo Witnesses.
