To all whom it may concern:

Be it known that 1, JOHN H.13onrnn, a subject of the King of Great Britain, and a resident of the city of Bellingham, in the county of Whatcom and State of Washington, have invented certain new and useful Improvements in Molding-Machines, of which the following is a specification.

My invention relates to apparatus for packing sand or similar material about patterns in molds and aims primarily to provide an apparatus of this character wherein the packing member is mounted for operation in a novel manner.

' Further, the invention resides in the provision of novel means for supporting the mold in a manner insuring of the sand being more firmly and uniformly packed by the packing member.

' With the above and other objects in View to be referred to as my description pro gresses my invention resides in the features of construction, arrangements and combinations of parts hereinafter described and succinctly defined in my annexed claims.

Referring to the accompanying drawings wherein like numerals of reference indicate like parts throughout: Figure 1 is a side elevation of the machine, parts being broken away. Fig. 2 is a top plan thereofwith portions broken away. Fig. 3 is an end elevation, aportion of the packing member or roll being broken away, and Fig. 4 is a vertical cross section taken on line H of Fig. 2.

Referring to the drawings by numerals ofreference, 1 indicates the packing mem ber or roll, the same being formed of annular sections arranged end to end and rotatably mounted on a shaft 2 mounted on a carrier 3 and having its projecting end porguide ways 4 of standards 5.

The bores of the component sections of roll 1' are of greater diameter than shaft 2, by which construction. the several roll sections arefreeof the shaft and one another for limited relative movement, thereby enabling the same to have their weight'so imposed on the sand as to insure a more perfect packing action.

Standards 5 arefixedto a base or bed 6, conveniently supported by legs 7, and have their upper end portions unitedby a cross beam 8, on which latter I journal a drum 9 which drum is connected by a flexible con- 1 nection, or cable 10 to carrier 3.

Fixed to the shaft of drum 9 is a worm wheel 11 with which meshes a worm 12, fixed to a drive shaft 13, journaled in stands 14:, and provided with a fixed sprocket wheel 15 and a normally loose pulley 16, which latter is adapted to be driven by a belt, not shown.

Reference numeral 17 indicates a clutch part splined to shaft 13 and adapted to be moved by a suitable lever, as 18, into and out of engagement with a clutch part 17 of pulley 16.

Reference numeral 19 indicates a hand wheel, journaled on a stub shaft of one of the standards 5, and provided with a sprocket wheel 20, taking over which and said sprocket wheel 15, is a chain 21.

With clutch parts 17 and 17 engaged, pulley 16 transmits power to shaft 13 to elevate roll 1, and when the latter is sufficiently elevated and the clutch opened, it will be held by worm wheel 11 and worm 12 against accidental lowering in its adjusted position which can be varied in a downward direction manually through operation of hand wheel 19. I

Reference numeral 22 indicates an endless conveyer on which a mold, as 23, is placed and fed beneath roll 1.

Conveyer 22 which conveniently comprises a plurality of endless belts arranged side by side and taking over broad sprocket wheels on drive and driven shafts 24c and 25 respectively, has its upper run extending over and slightly elevated from bed or base 6. At a point directly beneath roll 1, bed or base 6118 cut out, as at '6, and through this cut-out an idler roller 26 projects sufficiently above the bed or base to support the upper run of the conveyer and prevent un due friction between the latter and bed or base 6 incident to the passage of mold 23 beneath roll 1 during the packing operation.

Drive shaft 21 is provided with a friction wheel 27 adapted to be driven by a friction driver 28 fixed to a shaft 29, provided with a pulley 30 over which a belt, not shown, takes. Shaft 29 is ournaled in a slide bearing 30 which is conveniently guided in a guide way 31, provided on the under face of bed or base 6, and connected by a link 32 with a bell crank lever 33 which in turn is connected by a link 34 with a treadle 35.

In operation, following the placement of the mold 23 on conveyer 22, roll 1 is lowered into operative position for packing, through proper manipulation of hand wheel 19, fol lowing which, the operator applies his foot to treadle 35 to advance and hold driver 28 against friction wheel 27.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States of Amerv ica, is

1. In apparatus of the character described, means for support-ing a mold substantially horizontally, a vertical guide means, and a sand packing roll supported for rotation and guided in said guide means for movement toward and from said first scribed, means for supporting a mold, a

shaft, means supporting said shaft at the side of said first means, and a roll on said shaft having a bore of relatively greater diameter than that of the shaft whereby it is free of the latter for independent movement in a direction away from said first means.

3. In apparatus of the character described, means for supporting a mold, a carrier guided for movement toward and from said first means, fiexible'means connected with said carrier for elevating the same, a shaft on said carrier, a packing roll mounted on said shaft, said roll being composed of a pluralityof annular sections arranged end to end and havingbores of relatively greater diameter than that of said shaft, whereby they are free of one another and said shaft for relative movement in a direction away from said first means.

4. In apparatus of the character described, means forsupporting a mold, a vertically arranged guide projecting above said 1Tl6t1l1S,'{L packing roll, a carrier for said roll slidably engaged with said guide, a drum, a flexible connection between said drum and said carrier, and means for driving said drum comprising a worm and worm wheel in mesh.

5. In apparatus of the character described, means for supporting a mold, a vertically arranged guide projecting above said means, a packing roll, a carrier for V said roll slidably engaged with said guide,

scribed, means for supporting a mold, a sand packing roll supported for movement toward and from said. means, and a shaft extending through said roll and rotatably supporting the same, the bore of said roll being of relatively greater diameter than that of the shaft whereby it is free of the latter for relative movement toward and from said means. I
