UNITED STATES PATENT orrrcn JOHN H. STEWART AND JOHN M. SCHENK, OF WATERLOO, IOWA, ASSIGNOBS TO CEMENT TILE MACHINERY COMPANY, OF WATERLQO, IOWA.
romvinannnn Eon SEWER-PIPE MACHINES.
Specification of Letters Patent.
Patented Apr. 4, 1916.
To all whom it may concern Be it known that we, J OHN H, STEWART and JOHN M. Sena-n11, citizens of the United States of America, and residents of later- 100, Blackhawk county, Iowa, have invented certain new and useful Improvements in Former-Heads for Sewer-Pipe Machines, of which the following is a specification.
Our invention relates to improvements in former-heads for sewer-pipe machines, and the object of our improvementis to furnish a rotatable or spirally movable former-head adapted to work within a mold-casing, and equipped with forming means for the bell or outwardlyoffset part of the pipe section to be shaped from cement or concrete in said casing, the forming means for the bell part,
being so linked and connected to the'other parts of the former-head as to be recessive or-protrusive to take them out 0% or into their radii of action without interference. This object we have accomplished by the mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawings, in which,
Figure 1 is a vertical axial section of a sewer-pipe mold casingandof our improved former-head as operative therein, with parts broken away. Fig. 2 is a horizontal section of said parts, taken on the line a?; of Fig. 1, and looking in the direction of the arrow.
Similar numerals of reference denote corresponding parts throughout the several views.
This invention is an improvement upon our device applied for under application Serial Number 817,208.
The numeral 15 denotes a hollow cylindrical mold-casing,-provided with'an. ex-' panded bell head at its lower end, within which may be formed a sewer-pipe of 0on crete, to be formed by included mechanism as hereinafter described. Said mold-casing rests coaxially upon the hollow cylindrical base-block 17, whichv latter forms part of the revolving carriage of a tile machine, not shown. A. pallet 14: of annular form is seated within the expanded portion of said casing 15, and flanged to close the lower end thereof, the pallet having offset part extending first upwardly and then inwardly to fit about a cylindrical former-head 1 movable spirally and vertically therethrough,
and mounted on the lower end of a shaft 2. The space between the upright part of the outer parts are in line vertically with the.
circumferential periphery of the formerhead 1. Said sleeve 4 has oppositely projecting integral lugs 8 located intermediately between the projections 3 and orificed transversely to receive the pivot bolts 7 on which are mounted the pairs of arms -9,10, 7
the latter being connected at their outer ends after being brought convergently together by means of the pivot bolts 11. q
The numeral 16 denotes rods whose lower parts are bent laterally at an angle to their main parts and pivotedat the said angles to thepintles; 11. The laterally directed parts 12 of said bars 16 are bent downwardly and rearwardly relative to the direction of rotation of said former-head at 13 as shown, to
extend downwardly into. the space between the upright part; of the pallet 14 and the expanded part of said mold casing 15. The upwardly directed parts 16 are pivotally' connected at their upper extremities to lugs- 19 depending from a collar 18 which is slidably non-rotatably mounted on the shaft2.
Thenumeral 22 denotes a lever, one end of whichispivotally. and adjustably mounted; at 25 on a fixed bracket or arm 26. Said] arm is slotted atf23 to receive a pin24i projecting from a collar 21 rotatably mounted upon S1eeve 18. I
When the lever; 22 is raised or lowered, it shifts up and down the sleeve 18 with the pivotally connected rods 16 to swing up or down the arms. 10 to thus act upon the trowelingparts 1213 in either elevating them, as indicated by the dotted lines in Fig. 1, to positionslocatedentirely within the outer limit of action of the rotary former-head 1, or to drop said troweling parts to project into the annular interspace'v around the pallet 1d. The working positionsof the troweling parts. 12.-13' are indir catedin said Fig. 1 by full lines. When thus projected down into said annular interspace, said troweling parts act in packing by rubbing the concrete thereinto and against the end closure flange of said pallet to form the outwardly flanged bell of the sewer pipe. The troweling action of the down-turned parts 13 of the arms 12 is facilitated on account of their being directed obliquely rearwardly relative to the direction of rotation of said former-head 1. Then the lever 22 is used to swing up the arms 10 and withdraw the said troweling parts, as heretofore described, the former-head 1 with its fixed troweling surfaces 5 moves up spirally to the casing 13 and forms the cylindrical part of the pipe. Any desired means may be used for actuating the former-head 1 to form the pipe within said mold.
Having described our invention, whatwe claim as new, and desire to secure by Letters Patent, is:
1. In combination, a mold-casing having one end expanded in diameter, a pallet closing the expanded end having a raised inner concentric part spaced from the inner wall of said expanded part, and a packing tool within said casing movable into and out of the space between said expanded part and the raised part of the pallet and rotatable therein to pack concrete within said space to form a bell-shaped mouth on a tile formed in said casing.
2. In combination, a mold-casing for hollow tile having one end expanded in diameter, a pallet closing the expanded end of said pallet and having an internal raised wall spaced from the expanded part of said casing to provide an annular end trough therebetween, and a packing arm mounted pivotally within the casing, movable into and out of said end trough to pack thematerial upon the pallet to compress and consolidate the material at the terminal edge of the bell-shaped end of the tile formed in said casing. 7
8. In combination, a cylindrical mold-casing having a bell-shaped end, an annular pallet closing said bell-shaped end and having a raised inner wall extended concentrically into said bell-shaped end, a cylindrical former-head movable rotatably and longitudinally through said pallet and casing, and a bent arm connected to said former-head, movable into the space between said bellshaped end and the raised wall of said pallet and adapted to be retracted from said space above said former-head to lie within the outer limits of said head.
4. In combination, a cylindrical mold-casing, an annular pallet adapted to removably close one end of said casing, a rotatable cylindrical former-head movable longitudi nally through said casing, and an arm mov" ably connected to said former-head and movable toward the end of the casing closed by said pallet to pack materials against the closure part of the pallet, said arm being adapted to be retracted into the casing space above said former-head within its outer limits.
5. In combination, a stationary cylindrical 7 mold-casing having a bell-shaped end, an'
annular pallet fitted over said bell-shaped end, a rotatable former-head movable longitudinally through said pallet fittingly and through said casing spaced concentrically from the inner wall thereof, and a downwardly bent arm movably connected to the top of said former-head and adaptedjto swing out and down into the bell-shaped end of the casing to pack materials against the end-closure part of the pallet.
6. In combination, a mold-casing with a flaringend, an annular pallet seated in the elevated to be withdrawn entirely within the limit of action of the circumferential periphery of said former-head when raised, an upwardly-directed bar integral with the second-mentioned arm, and means for moving said bar up and down to rock said first-mentioned arm vertically.
7. In combination, a hollow mold-casing,
means for partially closing one end of said casing adapted, in coaction with the inner wall of the casing, to provide a trough-within and about said'end, opening into the casing in the direction of its length, and a troweling-tool within said casing, movable into or out of said trough and adapted to be propelled within and along it to trowel material deposited within the trough to 7 form a tile-end therein.
