MOLDING-MACHINE.

My invention relates to apparatus for packing sand or similar material about patterns in molds, and has for one of its objectsto provide a construction of this character embodying a rotatable packing member which is mounted for operation in a novel manner.

Other objects will be set forth as my description progresses, and those features of construction, arrangements and combinations of parts on which I desire protection, succinctly defined inmy-anneXed claims.

Referring to the accompanying drawing, 1

wherein likenumerals of reference indicate like parts throughout: Figure 1 is a top plan. Fig. 2 is an end elevation with parts broken away, and Fig. 3 is a vertical longitudinal section.

Referring to the drawing by numerals of reference 1 indicates the packing roll or cylinder, the same being journaled in a frame 2 which is suspended by flexible connection 3, consisting of a short length of chain, from a carrier 4 which is provided with roller 5 engaged on a track 6. Frame 2 is provided with forwardly projecting side extensions 2' to which is secured a handle 7, which latter can be grasped by the operator to advance and retract the roll 1, carrier at moving on track 6 to permit of this, as is apparent. Flexible connection 3 is provided with end hooks 3 which are i normally engaged in eyes of the carrier 4 and frame 2, as clearly shown in Fig. 2. Through the provision of flexible connection3, the pressing roll is permitted to have a slight upward movementwhen brought into engagement with the sand, and the roll at such time will have its full weight imposed on such material. Track 6 constitutes a horizontal extension of a vertical support 8 which latter is mounted for vertical and rotary adjustment in a guide 9.

In the present embodiment of my invention, I aim to provide a construction which is portable, the same comprising a truck 10 having supporting wheels 11 and Specification of Letters Patent.

conveniently provided with stand 12 for the mold 13. Guide 9 is fixed to truck 10 and spaced from stand 12 longitudinally of the truck. The support 8 extends through guide 9 and the body or bed of truck 10 and has its lower end engaged 011 a bearing 14, consisting of a roller journaled in the free end of an arm 15, fixed to a horizontal rock shaft 16, j ournaled in depending bearings of truck 10. Rock shaft 16 isprovided with an operating handle or lever 17, through the medium of which said shaft and arm thereof can be swung to effect vertical adjustment of support 8. For holding lever 17 in its adjusted position, I provide the same with a latch 18, adapted for engagement with a rack 19 fixed to a truck 10. Latch 18 is connected by a link 20 to an operating han die 21.

-In the operation of my apparatus, track 6 is first lowered to enable roll 1 being advanced to pack the sand in drag or bottom section of mold 13, following which and after the cope is applied, track 6 is elevated, and roll 1 again advanced.

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

1. In apparatus of the character described, means for supporting a mold, a

packing roll for operation on a mold supported on said means, a frame in which said roll is journaled, an elevated track, a carrier on said track, and a connection secured to said carrier and to said frame, said connection being flexible whereby the roll can move upwardly independently of the carrier through resistance of the material being pressed during a packing operation and be suspended thereby when it is removed from the mold.

2. In apparatus of the character described, means for supporting a mold, a packing roll for operation on a mold supported on. said means, an elevated track, a carrier on said track, and a flexible connect ing means depending from said carrier and supporting said roll, whereby the latter is free of said carrier for relative upward movement during a pressing operation.

3. In apparatus of the character described, means for supporting a mold, a roll for packing the sand in said mold, a

track, means supporting said roll from said track for movement across the face of the mold, and means carrying said track for vertical adjustment.

4;.In apparatus of the character described, a track, means supporting said track for vertical and rotary adjustment, a carrier supported for movement on said track, a packing roll suspended from said carrier, and means for supporting a mold for operation thereon by said roll.

5. In apparatus of the character described, a truck, a horizontal track, means supporting said track for vertical and rotary adjustment, means on said truck beneath said track for supporting the mold, and a sand packing roll suspended from said track for movement over and crosswise of said last named means.

6. In apparatus of the character de scribed, a vertical support, means supporting said support for vertical and rotary adjustments, a track carried by and projecting from the side of said support, a packing roll, means carrying said roll mounted on said track, means for supporting a mold, and means for vertically adjusting said vertical support.

I11 PP ratus ofthe character de scribed, a substantially horizontal track, a vertically disposed support, a truck, means on said truck rotatably receiving said support, a packing roll, means on said track carrying said roll, a lever having the lower end of said vertical support seated thereon,

packing roll for operation on a'mold supported on said means, an elevated substan tially horizontally disposed track, means supporting said track for horizontal adjustment With respectto said first means, a carrier on said track, and a connection secured to said carrier for supporting said roll, said connection being flexible whereby the roll can move upwardly independently of the carrier during a packing operation.
