CHARLES G. ELMORE,

0F JACKSON, MICHIGAN.

MACIIINE FOR MAKING TILE AND THE LIKE.

'QSBAAS.

To all whom it may concem:

Be it known that 1, CHARLES G. ELMORE, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented a certain new and useful Improvement in Machines for li iaking Tile and the Like, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

lily invention relates to machines for making tile and similar articles.

Prominent objects of the invention are to provide a simple, practical and effective machine for making such articles, to arrange for the easy and ready operation and control of the same, to assure a high degree of ei'liciency in the use of material and operatioii of the machine, and to accomplish the foregoing and other desirable results in a simple and expeditious manner.

In the accompanying drawings, Figure 1 is a mixed perspective and sectional view of the said machine, the section being taken upon a vertical plane erected upon line a a, Fig. 1. Fig. 2 is a perspective view of plate K with the upper core L attached thereto. Fig. 3 is a perspective view of the tile jacket F. Fig. 4 is a sectional view of ring or collar D taken on a vertical plane erected on the line a a, Fig. 1. Fig. 5 is a side elevation of the machine showing parts in dis charging position.

The machine which I have shown in the drawings for carrying out my invention is provided with a base B, from which arises the perpendicular standard A, having a flange 1 extending longitudinally of the front side and having a slanting topportion to which is bolted the bowl-shaped ring or collar 2, while just below upon the perpendicular port-ion of said flange is bolted the double ring or collar 3. From the lower portion of the double ring or collar 3 and upon either side of the machine the guiderods 0 extend perpendicularly downward to the base B, having both ends thereof rigidly attached in the position represented. The parts described thus provide a rigid framework forming supports and guideways for the various operating parts of the machine, which include a tamper and feed device 19- 21, an annular chamber, having a fixed upper portion and a movable lower Specification of Letters Patent.

- portion, means for actuating the movable lower portion, and a cut-off M.

The ring or collar D, Figs. 1, 4c and 5, fits loosely and slidably about the core E, forming a floor for the annular chamber, hereinafter described, and is provided with a flange upon its upper surface, Fig. 1, to support and retain the jacket F, Figs. 1 and 8. The said ring or collar D is also provided with an offset 4, Figs. 1, 4t and 5, which is conveniently shaped and bored to form a guide by which it is mounted for slidable attachment upon the guide-rods C. The said offset 4 is also conveniently shaped to provide a pivotal attachment for the con necting-rod G. Said oflset 4 as arranged for guide and pivotal attachment described is duplicated upon the opposite side of said ring D.

The core E is a hollow cylinder closed at the top, of suitable dimensions, being slightly larger at the bottom where it is provided with a flange 5, said flange being provided with a plurality of offsets 6 6, from each of which arises a rod or bar 7 7 These rods or bars support the ring or collar 8 at their top, thus forming a rigid frame or cage 5 8, in the center of which is the core E. The said cage 5-8 is provided with the oflsets 9 upon the ring 8 and oflset 10 upon the flange 5, both of said offsets being in duplicate and conveniently shaped and bored to form guides to engage the duplicate guide-rods C upon either side of the machine, thus providing a rigid and suitable carriage for the vertical reciprocation of the core E. Said offsets on ring 8 are supplementary guides for use in larger machines and may be omitted, together with ring 8 and the supporting rods 7 in smaller machines.

To maintain the cage 5 8 with the core E, also the ring or collar D with the jacket F, in their proper position and relation both at rest and in reciprocation upon the guiderods 0, the connecting rods G and H are pivot-ally attached at their lower ends to the offsets 4. and 10 respectively, while the upper end of the connecting-rod H is similarly attached to the upper end of the arm 11, and the upper end of the connectingrod G is also similarly attached to the arm 11 near the shaft 12. Upon the opposite side of the machine is a precisely similar arrangement, except that the arm upon the opposite end of the shaft 12 is elongated above the upper attachment of the longer connecting-rod H, forming the lever 13,,both arm 11 and lever 13 being keyed to the shaft 12. To reach its upper or normal position the lever 13 passes somewhat beyond the center of rotation and comes to rest at stable equilibrium upon the offset 14 upon the ring or collar 2, thus maintaining the core E, the

cage 5S, the ring or collar D, the jacket F firmly in their upper or normal position.

The arrangement of the above parts is such that while in their upper or normal position, the jacket F being supported upon 15 the ring or collar D within the flange thereon, Fig. 4, the top of the said jacket F is confined within the lower portion of the double ring or collar 3, and the core E is supported within the said jacket F, is con- 2 centric therewith, and being of somewhat less diameter and of equal height, an annular chamber or tilemold is formed, of which the ring or collar D is the floor.

. Further, the arrangement of the above parts is such that when the lever 13 is rotated for ward and downward to its lower position Fig. 5, the ring or collar D is actuated downward by the connecting rod G; while the cage 58, with the core E is actuated much furtherdownward by the connecting rods H bringing the top of the core E approximately to the plane of the bottom of the jacket F. In this manner, the jacket is disengaged, may be removed and another substituted.

The bowl-shaped ring or collar 2, bolted to thetop of the standard A, is provided with a plurality of horizontal off-sets 16 16, extending around the inner circumfer- 40 ence near the top thereof. It is also provided with the adjustable stop 26. The ring or collar 15 is adapted to support the hopper I, to fit loosely within and rest upon the top of ring or collar 2 without being in contact with plate K. The double ring or collar 8 is arranged for guides and attachment of the cut-off M, rigidly supports the jacket J and the guide rods C, and detachably supports the'jacket F. a The plate K is saucer-shaped, having a flat bottom and provided with a horizontal flange extending outwardly from the top thereof by which it is rotatably supported upon the offsets 16 uponthe inner surface of the ring or collar 2. It is also provided with two offsets or stops 25 arranged to interfere with the adjustable stop 26 in the ring or collar 2 in such a manner as to limit the rotation of plate K and the tamper and feed device 1921 to the length of the tamping irons 19. The plate K is provided with a flat bottom, which also constitutes the floor of the hopper I without being in contact with the sides thereof. On the under side of said bottom is a circular flange concentric with and substantially equal in diameter to the core E below. Upon said circular flange is rigidly attached a hollow cylinder or upper core L, concentric with and substantially equal in .diameter to the core E. Said cylinder is conveniently constructed of thm metal, extends downward and terminates slightly above the cut-ofl M.

J is an upper jacket conveniently constructed of thin metal, is concentric with the upper core L, is rigidly attached at the top, within the ring or collar 2, and at the bottom within the upper portion of the double ring or collar 3, the upper core L and the core E being equal in diameter and the jacket J being equal or greater in diameter than the jacket F, and all being concentric about the same vertical axis. A supplemental annular chamber or upward extension of the tile-mold is formed of equal or greater diameter than the said tile-mold thus providing for the efficient operation of the tamper and feed device 1921 and aflording, in connection with the slots 17, Fig. 2, a passage from the hopper I to the tile-mold. Platel Kjs also'provided with one or more slots 0' out away portions 17, Fig. 2, curved in conformity to the annular chamber below and arranged to form one or more passages or; openings from the hopper I to the said annular chamber for the passage of material and also to accommodate the tamper and feed device. hereinafter described.

The tamper and feed device consists of one or more curved tamping-irons 19, altcrnating with an equal number of vertical rows or ranks of horizontal curved feed-ha rs 20, all supported upon one or more perpendicular rods 18, forming a rigid cylindrical framework conforming to the annular chalnher .in which they operate, said rods 18 being somewhat longer than the combined height of the entire annular chamber and hopper and having a handle 21 attached to the upper ends as shown in Fig. 1.

The cut-off M consists of a disk having a handle and is conveniently pivoted between the upper and lower portions of double ring or collar 3 in such a manner that when the tamping device 1921 .is raised above it, the said cut-oft may be swung backward, passing entirely through between the upper and lower parts of said ring or collar 3, also between the upper core L and the main core E, thus forming a partition dividing the annular chamber into upper and lower portions. In'this position, it forms a floor for the upper annular chamber upon which may rest the contents thereof, including the tamping device 19-21.

Fig. 3 represents the jacket F in its opened or relaxed condition. It is conveniently constructed of a sheet of somewhat elastic metal rolled .into the form of a pipe or hollow cylinder of proper dimensions to fit the 130 supporting rings D and 3. A strip of metal 22, Fig. 3, is doubled upon itself at one edge and riveted to one edge of thejacket F, extending longitudinally of its outer surface so-as to form a recess to receive and retain the other edge thereof. One or more short springs 23 are riveted transversely of one edge, projecting somewhat beyond, the free end of said spring, being turned outward and perforated with a hole to engage a pin 24 in the opposite edge when closed. When the spring is actuated to release the pin, the jacket opens. The lower end of the said jacket is turned inwardly, forming a narrow ledge or support for the tile or other article, when the same is being removed from the machine. Said edge or support may be notched or cut, in order that the jacket may retain its elasticity. A suitable number of jackets may be provided so that the tiles or other articles may be formed therein and so retained until hardened.

The operation of the device is as follows: The parts of the machine being in position as represented, the hopper I is filled with a suitable mixture, from which the tile or other article is to be formed, such as cement, sand and water. The tamper and feed device 19-21 is raised, and then together with plate K is rotated horizontally as far as the stops 25 and 26 will permit. It is then actuated forcibly downward, then raised and rotated .in the other direction as far as said stops will permit, then actuated downward as before. At each downward reciprocation of the tamper and feed device 19-21, a portion of the mixture is carried from the hopper I, by the curved feed-bars 20 through the curved slots 17, Fig. 2, and precipitated through the upper annular chamber into the lower annular chamber or tile-mold between the tamping irons 19. As the length of the said tamping irons, the space between them, and the distance the tamper and feed device 1921 is rotated are equal, the material deposited between the tamping irons at one downward reciprocation is tamped at the next. The above described operation is repeated until the annular chamber is filled above the cut-off M with compressed material. The said cut-off M is then actuated backward between the above described upper and lower annular chambers, leaving the completed tile in the lower annular chamber or tile mold, while the contents of the up per annular chamber, together with the tamper and feed device 1921 is supported upon the said cut-off M. The lever 13 1s 1 then rotated forward and downward actuating arm 11 in unison therewith, thus actuating the connecting rods H, which in turn ac .tuate the cage 5-S and the core E down ward. At the same time, connecting rods G are actuated, which in turn actuate ring D, and the jacket containing the tile downward a much less distance. When the lever 13 reaches its lowest position Fig. 5, the core has been extracted from the tile, and the cage 58 is below the jacket F, while the said jacket is disengaged from the retaining ring 3, thus allowing the free removal of the jacket and its contents. Another jacket is substituted, the lever 13 is rotated upward, bringing the core E, the ring D, and the jacket F to their upper or normal position, where they are firmly maintained. The operation may then be repeated.

It will be understood that changes and modifications may be made in the machine herein set forth without departing from the spirit of my invention.
