' MACHINE FOR LINING Vi/ATER OR OTHER PlPES,

SPECIFICATION forming part of Letters Patent No. 274,138, dated March 20, 1883,.

Application filed November 10, 1882. (No model.)

To all whom it may concern: 7

Be it known that l, GALEN W PEARSONS, a citizen of the United States, residing at Kansas City, in the county of Jackson and. State i 'ing drawings, in which- Figure 1 is'a vertical elevation, broken to show indefinite height; Fig. 2, a plan of the top of the machine, and Fig. 3 a plan of the bottom after-the removal of the pipe.

Similar letters refer to similar parts throughout the several views.

The box A A and the posts BB B B constitute the frame-work of the machine. In-the top of the box is an opening corresponding in the size of its lining 0 0 tothe finished interior diameter of the pipe. The'lining 0 O is elastic, being slightly drawn back by the screwspp pp, working in the nuts Q Q Q Q, or their equivalent, to allow the insertion of the plunger-guard H, and afterward adjusted to it. The guard H, which is attached to the plunger G, is made of canvas or other textile material kept in form by coiled wire or other equivalent device. The plunger G is of wood or hollow metal, so as not to cool the melted material resting upon it. It is provided with guides I to keep it central.

0 Uis the pipe. f

1) D is a spout attached to'a frame, E E E, sliding upon the posts B B B B, the spout forming a'giiide to the top of the pipe, and also, by the raised guard F, a guide to the lift ing-rod K, the spout being for the purpose of carrying 011' surplus material, and for thepurpose of preventing accumulation of such material by cooling may be heated by steam or otherwise, as most convenient. The rod K fastens to the plunger-guide I by a clutch. Whenraised to the top of the pipe the guide, striking the gum d F, lifts the spout and frame off the pipe, thus permitting its removal.

N is a water-pipe entering the box A A. It

is continued by a hose hung to the plunger G for the purpose of maintaining a circulation of cool water in the upper part of thepipe C C as the plunger G rises.

M is a flexible hose, permitting the water to obtain a uniform pressure upon the bottom of the plunger G. The end of this hose is attached to the cross-bar L of the rod K and rises with it, either by Water-pressure alone or in part, as may be desired. 7

The action of the device is as follows: The plunger Gbeing placed in the position shown in the drawings, the pipe 0 is placed in position, the upper frame and spout being lowered upon it, holding it down and in place. The rod K isnow lowered, and, engaging with the plunger-guide I, is ready for lifting the plunger G, with its follower H. Molten asphaltum or other material in sufficient quantity to line the pipe is now poured into it, the box A A being full of water, between which and the molten material the flexible ring 0 O'forms a partition. Water being now admitted by the pipe N, overflows through the hose M, as the plunger G and its guard H are lifted in whole or in part by its pressure. The molten material flowing outside of the plunger G is held in place by the guard H, which, being of textile material and wet, does not adhere to it,

but cools it sutliciently to keep it in place, the

water rising and filling the pipe, completing thecoolingprocess. Whentheplungerreaches the top of the pipe tbe surplus material flows of)" by the spout D, and its further rise, lifting the spout audits framework, permits water to overflow the pipe without coming in contact i with the molten material and releases the pipe for repetition of the process with others.

I am aware that the lining of pipe with plas tic material is common, and that a plunger similar to the plunger G is used for the purpose. I therefore 'make no claim to the plun ger G. Neither do 1 claim the particular shape or arrangement of partsof the machine.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The method herein described of lining pipes with a material which will harden when coldythe same consisting in applying the material to the inside of the pipe, with a former or plunger working inside of said pipe, and
