Mom) RAM Application filed February 21, 1925. Serial No. 10,855'.'

Tov aZZ whom z't'mciz cancer n. Be it known that'I, JOHN BrNDEn, a citizen of the United States, and resldent of -New Hyde Park, in the county of Queens and State of New York, have invented certain new and useful Improvements in Mold Frames, of which the following is a specifi cation.

The present inventionrelates to improvements' in'inold-frames, and more partlcularly to a frame which is adapted to hold tubular filled molds, while the same are being carried through a baking oven. The molds, for which the frame is adapted, are particularly used in the production of art1- licial cork rods, the tubes packed with compositioncorkbeing mounted on the frame end the latter conveyed'through a baking oven, whereby the binding material, with which the cork granules is treated before the same is packed into '13l18 tubes, is coagulated or set, in a manner well known in the art. v

The mam ob ect of the lnvention is to provide a molcbframe which permits of convenientinsertlon of the tubular molds 111tO- and of an easy removal ofthe same from the frame, means being provided on the frame, .in. the form of studs, which serve for holding the molds in spaced relation and also for closing the ends thereof, to properly confine the material in the molds while being carried through the baking oven.

With these and other objects in View,

which will more fully appear as the nature of the invention is better understood, the

same consists in the combination, arrange ment and construction of parts hereinafter described, pointed out in the appended Figure 1 is a front elevation of a moldframe constructed in accordance with the present invention, with a plurality of molds member to side member of the frame, it

in position thereon; and Fig. 2 is a section taken on line.22 of Fig. 1. p i The mold-frame is rectangular in configuration and comprises two side members 10 and 11, which are connected by a lower end' member 12 and an upper end member13. The members 10, 11 and 12 are,-preferably, made of angle-iron, the end member 13 being a fiat stripof, a somewhat heavier gage. and bent into substantially U-shape, its legs 14 abutting against theside memberslO and 11. Immediately below the end member 13 there is fixed to the same a metal strip 15, which extends from side being disposed in theplane ofthe flange 16 o't'the cud member 12, as clearly shown in Fig. 2 of the drawings. and on the metalstrip 15 are mounted equidistantly spaced pins 17 and 18, respectively, the said pins extending at right angles to theeflange 16 and strip 15. The pins 17 are in registering positions with the pins 18, adjacent pins of each set being disposed at a distance from each other to permit of the insertion therebetween of a tubular mold 19. v

. To the flange 20 of the end member 12 is attached in any suitable manner a bar 21,- and to this barare riveted or otherwise secured studs 22, projecting above the bar 21, the arrangement being such that one stud is disposed between each two adjoining pins v 17. These studs are of a diameter to snugly fit into-an end of the tubes 19, securely closing the same. In alignment with the studs 22 is formed in the end member 13 a row of holes 23, through each end of the same projecting a stud 24, having a reduced end 25. These reduced ends are disposed below the end member 13 and fit snugly into the tubes 19. The studs 24 are fixed to a bar 26, disposed above the end member 18. This bar is provided in its upper face with" two notches 27, into each of which fits a disk 28, the two disks being eccentrically keyed or otherwise attached to asp indle 29. This spindle is journaled in bearings 30 on the legsl of the end member 13 and provided with a handle 31. Each disk is provided with a peripheral rim 32, in engagement with a lug 33 on the bar 26. Each 1 disk forms thus a double-acting cam, the

On the flange 16- 2 against the bar 26, while its inner face acts against the lug 33. It is obvious, therefore, that, when the spindle 29 is turned in one direction, the inner cam faces of the disks, in co-operation with the lugs 33, will cause the bar 26 and the studs carried thereby to 7 move upwards, while, when the said spindle is moved in the other direction, the outer cam faces of the disks act against the bar 26 and cause the same with the lugs thereon to move downwards.

The operation of this device is as follows: If it is intended to mount filled tubes on the mold frame, first the spindle 29 is turned in the direction to move the bar 26 away from the end member 13, that is to say, toward the said spindle, as far as the construction will permit. The operator places then each tube into the frame by slipping the lower end thereof over a stud 22, and dropping the upper end of the same between two pins .18 on the metal strip 15. After the required amount of tubes has been positioned upon the frame, the operator turns the spindle 29, to cause the reduced ends 25 of the lugs 24 on the bar 26 to enter the upper ends of the tubes positioned on the frame. The cam faces on the disks 28 are so designed that when the bar 26 is in its lowermost position, that is to say, when the reduced ends of the studs thereon are disposed within the tubes 19, the said bar is locked against movement. The frames, with the tubes thereon, are then placed onto a conveyor, carrying the same through a baking oven.

It is obvious that, when the tubes are filled with the cork material, the ends of the said tubes must be left empty, so that the studs on the frame will easily fit thereinto. These studs form covers for the tube, confining the cork material therein. The studs also constitute spacing means for the tubes.

lVhat I claim is 1. A frame for tubular molds comprising two side members connected by two end members, a row of fixed equidistantly spaced studs on one of said end members, a row of studs in alignment with said first-mentioned row movable on the other one of said end members toward and away from said row of fixed studs, and means carried by said. frame co-operating with said movable studs for causing the same, at will, to move simultaneously toward said fixed studs or simultaneously away therefrom.

2. A frame for tubular molds comprising two side members connected by two end men'ibers, a row of fixed equidistantly spaced studs on one of said end members, the other one of said end members being provided with a row of holes in alignment with said studs, abar movable on said frame, studs on said bar slidable in the holes in one of said end members, and means carried by said frame co-operating with said bar for causing the latter, at will, to move toward or away from said fixed studs.

prising a row of pins on each of said end members, the pins of one row being in alignment with those of the other row, the pins of each row being disposed between the respective studs.

Signed at New York, in the county of Kings and State of New York, this 20th day of January, A. D. 1925.
