Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed January 27. 1905. Serial No. 242,917.

To a/ZZ whom it may concern:

Be it known that I, ALLEN GLENN, a citizen of the United States, residing at Scranton, in the county of Greene and State of Iowa, have invented a new and useful Tile-Holding Machine, of which the following is a specification.

The present invention relates particularly to improvements in means for manufacturing cement or concrete tiles; and the principal object is to provide a novel machine of this character by means of which such tiles may be successfully produced with rapidity and at comparatively small expense. Another object is to provide a machine in which tiles of different diameters can be manufactured, the necessary changes and adj ustments to the machine being capable of convenient and ready accomplishment.

An embodiment of the invention which is at the present time considered a preferable one is illustrated in the accompanying drawings and is described in the following specification. The claims hereto appended will indicate, however, that the invention is not limited to this particular embodiment.

In the drawings, Figure 1 is a perspective view of the machine. Fig. 2 is a longitudinal sectional view through portions of the same. Fig. 3 is a detail horizontal sectional view, on an enlarged scale, through the tamper-operating means. Fig. 4 is a detail perspective view, on an enlarged scale, of the mutilated gear.

Similar reference-numerals designate corresponding parts in all the figures of the drawlngs.

In the embodiment illustrated a supporting-frame is employed, comprising suitable upright standards 4, mounted on a base 5. Journaled on this base at one side of the supporting-frame is an upright spindle 6, carrying at its upper end a mold-supporting table 7, the stem projecting through the table, as shown at S, and constituting a centeringpin, as hereinafter described. A drive-shaft 9, journaled on the standards 4 between the ends thereof, is adapted to be driven by any suitable source of poweras, for instance, manually through the medium of a handlecrank 10 or from a motor, the belt from which operates upon suitable loose and tight pulleys 11. Secured to this motor-shaft is a sprocket-wheel 12, connected to another has a central opening to receive the centeringpin 8. This base-plate carries an upstanding ring or annular flange 19 concentric to the pin and constituting a guide or keeper for the inner and outer walls 20 and 21 of the mold, thus being collapsible. It is to be observed these walls being constructed of sections, and that the inner wall 20 projects considerably above the outer wall and may be provided with a cap 22, having a central journal-stem 23 projecting upwardly from the same. A swinging journal-bracket 24 has a box 25 at its outer end, that receives the journal-pin.

For the purpose of feeding the cement or concrete to the mold a hopper 26 is employed, mounted above the mold-supporting table and having a suitably-hinged spout 27, that directs the material into the open top of the mold. Within this hopper is located an upright rotatable shaft 28, having agitatorfingers 29, said shaft carrying at its upper end a gear 30 in mesh with a gear 31, carried by a counter-shaft 32, journaled in the supportingframe. The shaft 32 is driven from another counter-shaft 33 through the medium of sprocket-wheels 34 and a sprocket-chain 35, and the shaft 33 receives its movement from the drive-shaft. To this end the said drive shaft is provided with a sprocketwheel 36, loosely journaled thereon and adapted to be connected thereto by a clutch 37, which clutch is operated by means of a hand-lever 38, and the sprocket-wheel 36 is connected to a sprocket-wheel 39 on the shaft 33 by means of a sprocket-chain 40.

Tamping mechanism coacts with the mold supporting table and the mold carried thereby, this mechanism consisting of averticallyreciprocating tamper-bar 41, mounted in a vertical guide 42, that is adjustably mounted on the supporting-frame by means of connecting-bars 43, extending transversely of said frame and secured thereto by suitable fasteners 44, passing through slots 45 in the bars 43. The upper portion of the tamperbar 41 has a rack 46, with which meshes a mulilated gear, (designated as a whole by the reference-numeral 47 which gear is ad ustably mounted on the end of the shaft 33. The gear, as shown, preferably comprises a body 48, on which are slidably mounted teeth-segments 49, the same being urged outwardly by springs 50, located behind said teeth. The teeth of these segments are arranged to mesh with the rack 46 of the tamper-bar. The said tamper-bar may also be movable laterally toward and from the gear, and for this purpose a guide-bar 51 is located against the side of the tamper-bar opposite the rack, the guide-bar being borne against by springs 52, which thus urge the rack toward the gearwheel.

Journaled in an ear 53 on one of the standards 4 of the supporting-frame is a bracket 54, having a handle 55 at one end and an outstanding arm 56 at its other end, which arm carries at its free terminal a finishing-scraper 57, that is adapted to be placed upon the open upper end of the mold. The bracket furthermore carries a depending leg 58, to the lower end of which is secured a brush 59, that operates upon the base-plate 18 about the bottom of the mold.

The operation of the machine can be briefly outlined, as follows The assembled mold hav ing been placed upon the table and the material having been inserted into the hopper upon operating the drive-shaft the table, and consequently the mold, will be rotated,while the said material will be fed into the mold. The rotating mutilated gear will intermittently elevate the tamper and permit it to descend upon the material in the mold, and as said tamper is raised accordingly as the mold fills the gear-wheel will continue to cooperate with the rack or with different portions thereof. Should the ends of the teeth on the gear wheel strike the ends of the teeth on the rack, either the rack or the teeth-segments of the wheel will yield suiiiciently to permit their relative movement until the teeth of one properly interfit with the teeth of the other, and thus all danger of breakage is avoided. When the mold is properlyfilled, the clutch 37- is operated to disconnect the sprocket-wheel 36 from the drive-shaft, thus stopping the tamper and the feed of the material. The table still continues to rotate, however, and consequently the finishing-scraper will properly act upon the upper end of the article in the mold, while the brush will remove any surplus material that falls upon the base. Now it is well known that tiles made of cement or concrete must stand in the molds a considerable time in order to set. In this structure therefore the mold may be bodily removed, the bracket 54 being swung out of the way and the j ournal-bracket 24 being disengaged from the cap, whereupon the base, with the mold-wall supported thereon, is lifted from the table and a new mold placed in position. The structure is then ready for continued op eration. If it is desired to make tiles of different diameter, all that becomes necessary is to provide molds of the proper size and to adjust the tamper toward or from the axis of rotation of the table. This is easily accomplished by adjusting the guide 42 with respect to the supporting-frame, and consequently with relation to the axis of rotation of the table. This will carry the tamper nearer to or farther away from the said axis of rotation, as will be apparent. The same longitudinal bracket can be employed, as it will assume a nearly horizontal position, being carried by the tamper-guide, and consequently adjustable therewith. While in this particular embodiment both the teeth-segments and the rack with which the same cooperate are shown as yieldingly urged toward each other, it is possible that either may be employed to secure the proper coaction between the teeth. It will thus be seen that a simple machine is provided, whereby tiles of different diameters can be expeditiously manufactured at com.- paratively small cost.

From the foregoing it is thought thatthe construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
