DEVICE FOR LIFTING- TUBES, TILES, AND THE LIKE.

Specification of Letters Patent.

Application filed November 11, 1911.

Patented May 14,1912.

Serial No. 659,871.

To all whom 225 may concern.

Be it known that I, FRANK L. VVA'rsoN, a citizen of the United States, residing at lVomer, in the county of Smith and State of Kansas, have invented certain new and useful Improvements in Devices for Lifting Tubes, Tiles, and the Like, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to new and useful improvements in the class of devices known as tube clamps and more particularly to a device adapted for use in lifting tubes or tiles of any character, and my object is to provide a device of this character which may be readily inserted within a tube or pipe engaged with the lower edge thereof and raised to correspondingly raise the pipe.

A further object of the invention resides in providing a device having a plurality of arms or hook members adapted to engage the tube or pipe, and a still further object resides in providing means in connection with said arms for the expansion and contract-ion of the same.

Still another object of the invention re sides in providing a device which is extremely simple and durable in construction, inexpensive to manufacture, and one which is very efficient and useful in operation.

With these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application, Figure 1 is a side elevation of the device. Fig. 2 is a top plan view thereof.

In carrying out my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a collar of any desired size having formed thereon a plurality of ears 2 arranged in pairs, there being preferably three sets of the same, and pivoted between each pair of ears 2, is an arm 3, the lower or free end of which has formed thereon, a lug or the like 1, whereby said arms 3 may be termed hook members or the like. The collar 1 has secured thereto at diametrically opposite points thereon, the ends of a rope or cable 5, whereby the device may be raised and lowered, and disposed between the arms 3, is a substantially cone-shaped follower or the like 6 which comprises a lower ring or band 7, a plurality of spokes or the like 8 and a head piece 9. These parts 7, 8 and 9 are all formed integral, the same outlining, as stated above, a substantially cone-shaped member, and formed on the ring or band 7, is a plurality of cars 10 arranged in pairs through which the respective arms 3 are dis posed. Bolt-s 11 extend through the pairs of ears 10, thereby forming guide members of the ears for said arms, and it will be seen that the follower 6 is adapted to be raised and lowered on the arms 3. In order to provide for this raising and lowering of the follower, an eye bolt 12 is swivelly arranged in the head portion 9 of the follower and has engaged therewith, an additional rope or cable 13 which extends through the collar 1, and from this construction, it will be seen that the follower may be readily raised and lowered with respect to the collar 1 by means of the cable 13 and the complete device raised or lowered by means of the cable 5.

In operation, should it be desired to re move, or rather lift, a tube, tile or casing such as is used in wells, the complete device is inserted within the tube, tile or casing, as the case may be, and in so inserting this device, the operator first allows the follower 6 to extend to its lowermost position so as to contract the lower ends of the arms 3. The contraction of the arms will permit the device to enter the tube or the like, and the same is then allowed to extend to a point below said tube, whereupon the follower 6 is drawn upwardly by means of the cable 13 which will expand the arms 3 to allow the lug or hook portions 4 at the free ends thereof to extend beyond the outer periphery of said tube, and when the arms have been expanded in this position, the device is then drawn upwardly by means of the cable 5. The lug or book portions 4 of the arms will then engage the lower peripheral edge of the tubing and as the device is being drawn upwardly by pulling simultaneously upon the cables 5 and 13, it will be seen that the pipe will not alone be drawaupwardly, but that the arms will be retalned in their effective positions. When the pipe or tube has been raised, the cable 13 is released to allow the follower to be moved to its lowermost position, which will contract the lower ends of the arms to permit the release of the portions 4: from their engagement with said tube, whereupon the complete device may be readily removed from the tube or pipe.

From the foregoing description, it will be seen that I have provided a simple, in expensive and eflicient means for accomplishing the objects of the invention, but while the elements herein shown and de scribed are well adapted to serve the functions set forth, it is perfectly obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

What I claim is 1. A device of the class described, com.- prising a head member, a plurality of arms pivoted thereto and provided with laterally extending portions at their free ends, a follower of cone-shaped design disposed between said arms, guiding means carried on said follower engaging said arms to permit of the sliding movement of said follower thereon, suspension means for the head member, and means to raise and lower said follower.

2. A device of the class described, comprising a collar, a plurality of arms pivoted thereto and said arms being provided with hook members at the free ends thereof, a cone-shaped follower disposed between said arms, said follower having guiding means thereon through which said arms slidably extend, suspension means for the collar and parts carried thereby, and additional means extending through said collar for raising and lowering said follower with respectto the collar.

3. A device of the class described, comprising a collar, a plurality of arms having one of their ends pivotally secured to said collar, the free ends of said arms being provided with laterally extending hook portions, a cone-shaped follower disposed between said arms, said follower being provided with a plurality of guiding members through which said arms extend, suspension means for said collar and parts carried thereby, and a flexible connection swivelly engaged with through said collar to raise and lower the follower with respect to the collar.

4:. A device of the class described, comprising a collar, a plurality of arms having one of their ends pivoted thereto, the free ends of said arms beingprovided with laterally extending hook portions, a coneshaped follower disposed between said arms, said follower being provided with a plurality of ears arranged in pairs through which said arms extend, bolts extending through each pair of ears to retain the arms I between said ears, a flexible connection swivelly engaged wlth sald follower and extending through said collar to raise and lower the follower and correspondingly expand and contractsaid arms, and suspension 1 means for the collar and parts carried thereby.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
