. antifriction-wheel 32, mounted on a stud extending from the adjustable arm 30, which latter has a slotted opening and thumbscrew 31 workin therethrough to adjustably connect said arm to the upper end of the lever 33, which is medially ivoted on a stud 34, extendin from the upright 35. The lower end of said l ever 33 is pivoted on a stud 41, attached to the rear end' of a horizontal shifting bar. 40,- the inner side of whosefront end is provided with a ba'ckwardlybent.projection or tooth 61. A supporting-block. 54

' is placed between the front ends of the l pngi distances from the center of t tudinal timbers 42 and 62, so as to be a su1t-' able distance anterior to the fronflupright frame, and on this block rests a bearing i within which the vertical stub-axle 148 of a horiz'ohtal wheel (shown inFig. ,5 is rotatable. This wheel has diverging-spoke'sfii),

attached to arim'50'. Cross-pieces 52 com nect the spokes 69 equidistantly from. the

centerof the wheel and at their nuddlecplq lts b'ejgrthe upper ends-of the downwar y-iiiQ- iected pins 53. The spaces between the .s okes are, filled by removablesegmental made of a shape somewhat resembling thatof a bell, having an up )er central threaded opening to receive the t ireaded lower end 77 o the shaft 5 below the fillet 75. The lower edge of said former-head is beveled from the outside inward, that s ace of the outer surface .extendin upwar for a short distance beyond and a ove the said bevel being the shape of a fiatring with vertical edge. Just below the top horizontal surface of the former-head is another beveled surface, and the surface between the upper bevel and the fiat ring periphery is gradually increased in a developing swell from its upper to lower edges. Di'ametrically 0p osite each other are de ressions 78 and 79 in the outer swell,

one e ge of each depression on the'following side being abrupt and sharp and having the deeper portion of the depression excavated up to its line. From thence to the leading edge of the depression the hollowing diminishes to the vanishing-point, and the uses of these depressions in the former-head will be hereinafter explained full The mold for ti e sections is shown on a larger scale in Figs. 6 and 7. It consists of a cylindrical casing, preferably of an elastic material, as metal, in a thin plate bent to the j ace of the inclose required inner diameter and havi its vertical edges 7'0 7lgfianged out so as to ie parallel and in contact with each other when fastened' to ether. The flange is provided with stu s 76, which lie in a position to coincide with and passthrou'gh openings in the adjacent flange 71. The fastening means is represented bya clip73, pivoted on a stud 72, attached to the flange 71, and which is turned over to'hold the flanges together by means of the handle 74. We have shown in Fig. 6 the corrugations 45 around the casin 46, whose function it is to strengthen an stiffen the thin casing and also toform such A rejections and 'de ressions in the outer surf tile as to prevent the tile from becoming displ ced from the casing when being removed from-the machine to the place of deposit.

o The machine is operated in the following manner When the drive-wheel 18 has been put-in revolution through the use of any suitable source of power, the'rnovement of the worm-gear 64 63 causes the cam 26, also the camson the double cam-wheel 27, to revolve, on

The shaft 17 also putsin' motion thebevel- .gears 3 2, the latter rotating the vertical shaft 5 by means of the key 4 in the groove 57. The dotted lines in Fig. 1 now showthe rela- 1 tive positions of the parts of the machine in the moment when the former-head is about to start upward to form the tile Within the mold-casin 46. The full lines show the positions of t e same arts when the tile as been formed and the ormer-headhal's arrived at its'highest point of'upward movement.

When the former-head 1 1S in'fts' i'iowermos't.

position within the mold-casingfl'fi, h'quantity of cement sull'icicnt in amount to constitute one section of tile maybe de osite'cl within the 0 )en upper end of the mo d-casin ,so as to fail down between the interior su ace of the mold-casing and'the exterior i periphery of the former-head to the uppersur ace of the segmental plate 67.- The machine. is then put in motion, with a consequent rotation ofthe former-head 1, the movement of the cam 26 causing the lever "19,to gradually lift said former-head, thus giving it an upward spiral motion throughout the len th 0 the casing.

As the former head l spira 1y ascends its dey pressions 78 and 79 grasp and pull around with them a considerable portionof the ce- Y ment or concrete material, the effeotbeingto draw such material down within the space between the inner surface of the mold' c'asing 46 and the fiat zone of the former-herald. The consolidation thereby effected is enhanced and perfected by reason of the spiral rotatory movement and rubbin pressure of'the fl'alf' zone of the former-head. The actionof'thi-s fiat zone in its spiral upward movement is similar to that of the rubbing pressing movement of a masons trowel when applyin soft plaster to it wall. The progressive ru bing said last-named means and said pivoted table, and means for rotating and reciprocating said plunger, and for actuating said carliar-rotating means, and for raising said table out of engagement With said molds.

6. In a device of the type setforth, a rotatable mold-carrier, means whereby said carrier may be rotated, molds on the carrier, a plunger operating in the molds, a pivoted table for engaging the up er ends of said molds, means for retaining t e table in predetermined position, means for raising said table, means for operating said carrier-i otating means, and means for simultaneously rotating and reciprocating said plunger and for operating said table-raisingmeans, and said carrier-rotating means.

7. In a device of the type set forth, a rotatable carrier, with molds thereon, means for rotating said carrier, .a pivoted lever connected to said means, a plvoted table for engagement with said mold, a lever connected to said table for raising and lowering the same, aplunger, a pivoted lever connected to said plunger, -a shaft, cams on said shaft for operating said lever of the carrier-rotating means, said lever of the table, and said lever of the plun er, and means connected to the plunger an to the said shaft for rotating each of the same in syn'chronism.
