SPECIFICATION forming part of Letters Patent No. 506,557, dated October 10, 1893.
Application filed May 31, 1893.
To all whom it may concern:
Be it known that 1, JOSEPH SHARPE, of the city of Paterson, in the county of Passaic and State of.New Jersey, have invented certain new and useful Improvements in Machines for Making Pipes of Cement, Clay, or Similar Substances, of which the following is a specification.
This invention relates to a new and improved machine of simple construction for making pipes with a socket at one end, from clay, cement, composition or any substance of which drawings like letters of reference indiand others shown in section.
cate like parts, Figure 1 is a side elevation of the improved machine for making pipes from clay, cement, 850., parts being broken away Fig. 2 is a plan view of the cutting device. Fig. 3 is a horizontal section through the bottom of mold.
' the cutting device.
Fig. 4 is a side view of the outer mold and of In the drawingsA is a cy to the lower end of which the funnel shaped" ortapering bottom section -B is bolted, which in turn has a mold C- bolted to its bottom edge by means of boltspassed through lugs projecting from the top of said mold O, into the side of the section B- near the bottom edge thereof. The inner diameter of the mold O is equal to the outer diameter of the socket to be formed on "one end of the pipe to be produced. The mold C is bolted to the section B in such a manner that a horizontal annular slot D- is formed between the top edge of the mold C and the bottom edge of the section B. Through this slot the cutting off wire E is passed and the ends of this wire pass through two side pieces F- at opposite ends of the section .-B, and the wire can be drawn taut by nuts F screwed on the ends of the wire and resting against the outer edges of the side pieces -F-. The side pieces F- are connected by two semi-circular handlelindrical mold,
I engage with the recesses Q'.
Serial No. 476,052. (No model.)
bands or hoops G as shown in Fig. 2. The side pieces F are suspended by means of arms H from rods J- mounted to slide in sleeves K- bolted to the sides of the section B at the top thereof, and these guide sleeves K have longitudinal bottom slots through which the arms H can slide or pass. The section -B contains an auger shaped or screw presser M mounted centrally therein between an inner mold M and the outer mold B which presser, extending downward to the narrow opening between the inner and outer molds, revolves around the conical center mold M The exterior bottom diameter of the center mold M is equal to the bore or inner diameter of the pipe to be made and the inner diameter of the bottom B' of the mold -B is equal to the exterior diameter of the pipe to be made. The top of the bottom mold -O is rounded on the inside to conform to the desired shape of the exterior of the socket to be made on one end'of the pipe. 'A plat form N, with a center pin N, is at tached to a suitable rod or shaft which operates vertically.
On the top of the platform N- and centered on pin N' is an adjustable mold or core P for forming the interior of the socket or flange onone end of the pipe to be produced, said core or mold having a top piece Q provided with two opposite recesses Q for receiving the lugs R projecting inwardly from the bottom of the center mold M*. A foot lever -U' pivoted to the frame I supportingthe entire device is connected by a rod .U"- with a lever -W pivoted at -'W":zand having its other end so constructedasto" grip the pin S' which passes through the-:v'ierticalurod or shaft for forcing the platform which holds the adjustable core mold 'P' upinto the socket mold C until the lugs R The platform is raised by the hand until pin S, shown at the lower end of the vertical rod, can be engaged by the outer end of .lever W, upon which the parts are forced or pressed'into operative engagement for the purpose of causing the adjustable core mold -P to rotate with the inner mold -M which is secured to the shaft V-, whereby the cement or other material is forced out into the mold C over the core -P and a socket is thereby formed on one end of the pipe to be produced. The screw-presser M revolving forces the cement or clay composition down into the space between the inside of the mold O- and the exterior surface of the core or mold P thlfs shaping the socket of the pipe. The downward pressure on the platform increases when said space is filled and the socket is formed and the operator who has his foot on the lever -U notices this increased pressure and removes his foot and the clay or other material of cement composition, for example, is forced through the ring shaped slot between the bottom of the center mold M and the ring or bottom portion -B. of the outer mold B- thereby pressing the platform N' and the core P downward, and in so doing a pipe is formed the inner diameter of which is equal to the exterior bottom diameter of the center mold M and theexterior diameter of which is equal to the inner diameter of the ring portion B. The adjustable core mold P- ceases to rotate with the center mold M as soon as it is'lowered a sufficient distance for the recesses -Q to become detached or released from the lug R-. The platform gradually descends as the pipe is formed and when the pipe has the desired length it is cut off by moving the cutting of wireE across the bottom of the section B'. The cutting ofi Wire remains in this position until thenext pipe is formed which is in turn out off by moving the cutting off wire back again, ands'o on. When the completepipe is removed, the platform is raised and another socket and pipe formed. M
