UNITED STATES PATENT OEEICE.
JOHN E. EARLE, OF NEIV HAVEN, CONNECTICUT, ASSIGNCR TO J. P. LINDSAY, OF SAME PLACE.
IMPROVEMENT IN MACHINES FOR -MAKING `CEMENT PIPE.
Specification forming part of Letters Patent No. 49,827, dated September 5, 1865.
To all whom 'it may concern:
Be it known that I, JOHN E. EARLE, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Machines for Making Cement Pipe; and I do hereby declare the following to be full, clear, and exact description of the same, when taken in connection with the accompanying drawings and the letters ot' reference marked thereon, and which said drawings constitute part of this specification, and represent, in
Figure l, a side view, and in Fig. 2 a vertical central section.
In the manufacture of cement pipe the core and case formingthe liask have heretofore been ixed, and the stock placed around the core and pressed or tamped down. Owing to the narrow space around the core (between the core and case) the operation of lling and tamping is attended with considerable difficult-y.
The object ot' my invention is to overcome this difficulty, and consists in the arran gement and construction of the core so that it may be lowered to the bottom of the flask and gradually raised as the flask is iilled, thus giving the entire diameter of the case for the convenience ofthe workman.
To enable others skilled in the art to make and use my invention, Iwill proceed to fully describe the same as illustrated in the accompanyin g drawings.
A is the case, of any known construction, set upon a base, B.
a is a ring set within the iiask to forni one end of the pipe, and may be of any approved form.
C is the core. It is a cylinder ofthe diameter of the interior ofthe pipe to be made.
D is a scre\v-rod, and may be raised or low ered by turning the wheelfnut E accordingly. To this said rod the core C is secured by a pin, d, or in any other manner, so as to be easily detached.
When beginning to fill the .iiask the core should be down, as Fig. 2, and gradually raised as the iiask is filled, and when filled the core will stand in the position denoted in red; then the rod D may be detached from the core and the upper end of the pipe formed in the usual manner, and when the pipe is completed the core may be drawn out by means of the screwrod or i'orced down, at the pleasure of the operator.
It' thoughtbetter, the core maybe raised from the bottom instead of the top, as described.
I am aware that the core has been drawn from the flask after the pipe is finished, as in the patent of Henry Knight, May 3l, 1864; but in that, as in all other cases, the core is stationary and stands at its full height in the ilask while the pipe is being formed, causing a difficulty which is fully overcome by my invention. Therefore I do not claim raising the core from the flask after the pipe is formed 5 but Vhat I do claim as new and useful, and desire to secure by Letters Patent, is-
Raisin g the core in the flask during the process of filling, and only as fast as theiiask becomes filled, so that the top of the core is always down in the iiask at or near the point of filling, substantially as and for the purpose specilied.
JOHN E. EARLE.
