MACHINE FOR PACKING PIPE-JOINTS.

Specification of Letters Patent.

Application filed. April 22, 1909.

Patented Feb. 1, 191m.

Serial No. 491,568.

To all whom it may concern:

Be it known that I, CARROLL E. MILLER, J12, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in lVIachines for Packing Pipe-Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for packing pipe joints, and more particularly to machines adapted to pack the joints of cast iron pipes, such as water mains, gas mains, etc., and its object is to provide a device that is quickly and easily applied and operated, and to provide the same with various new and useful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure 1 is a plan view of a device embodying my invention as it appears in use; Fig. 2 a side elevation of the same with a part of the pipe 1 broken away; and, Fig. 3 an end elevation of the same as in Fig. 1.

Like numbers refer to like parts in all of the figures.

1 and 2 represent the adjacent ends of two connected cast iron pipes of the usual construction, the pipe 1 having an enlarged end 1 to receive the end of the pipe 2 and spaced apart therefrom to receive the packing 12 which is usually of lead or other soft metal, but may be of any suitable material.

3 represents a divided band adapted to surround the pipe 1 and engage the enlargement 1*, and 6 another divided band adapted to slide upon the pipe 2 and enter the chamber formed to contain the packing and force the latter into place. Each of these bands is preferably divided at opposite sides and detachably connected by intermeshing lugs 4: having alined openings therethrough in which openings are inserted removable pins 5, whereby the ends of the bands are secured to each other and may be readily applied to the pipes or detached therefrom by removing the said pins.

Attached to the opposite sides of the band 8 are arms 7 which extend outside of the enlargement 1 and parallel with and at opposite sides of the pipe 2 a suitable distance, to which arms 7 is detachably pivoted a bifurcated lever 8 by means of removable pivot pins 10, adjustable in holes 11, in the lever 8, and in the arms 7 to adjust the leverage and to accommodate the device to the amount of packing used. The lever 8 is connected to the band 6 to move the same on the pipe 2 by means of connecting rods 9 pivoted to opposite sides of the band at one end and to the ends of the lever 8 at the other end, the pins 10 also being preferably removable for convenience in using the machine.

From the foregoing description, the operation of my device is quite obvious. The band 6, sliding on the pipe 2, will enter the annular chamber between the end of the pipe 2 and the enlargement 1 and engage the packing and thus force the same to place by operation of the lever 8.

The device can be applied to pipes after the same have been assembled by removing the pins 5, placing the bands in place on the pipes, and again inserting the same in place.

What I claim is 1. A device for packing pipe joints, comprising a band adapted to be fixed on a pipe, a second band adapted to slide on a pipe and enter a packing space between the pipes, and a lever pivotally connected to the bands to move the last named band.

2. A device for packing pipe joints, comprising a band adapted to be fixed 011 a pipe, a second hand adapted to slide on a pipe and enter a packing space between the pipes, arms on the fixed band, a bifurcated lever pivoted to the arms, and rods connecting the lever and the movable band.

3. A device for packing pipe joints, comprising a divided band adapted to be placed around a pipe and fixed thereon, a second divided band adapted to be placed around a pipe and slide thereon, and also adapted to enter a packing space between the pipes, arms attached to the respective parts of the first named band and embracing the other band, a bifurcated lever adjustably pivoted to the arms, and rods connecting said lever and the movable band.

4. A device for packing pipe joints, comprising two bands divided at opposite sides and detachably connected by intermeshing lugs and pins removably inserted in the lugs, one of said bands adapted to slide on a pipe and enter a packing space between two pipes, and a lever connected to said bands to reciprocate the movable band.

5. A device for packing pipe joints, comprising two bands divided at opposite sides and connected by interineshing lugs and removable pins in said lugs, one of said bands adapted to be fixed on a pipe and the other adapted to slide on a pipe and enter a packing space between two pipes, arms attached to one of the bands and extending at opposite sides of the pipes and the other band and having a series of holes near their free ends, a bifurcated lever having a series of holes in each arm, removable pivot pins ad- 15 justable in said holes in the arms and lever, and connecting rods pivoted to the lever and movable band at their respective ends.

In testimony whereof I aflix my signature in presence of two witnesses.
