LVITW'ESS. LYVEJV'TUR.
BIj www HIS .dTTORJVEl WILLIAM TRIPPE, or HOLSTEIN; MISSOURI.-
CLAMBING-TOOL.
To all whom it may concern:
Be it known that i, WILLIAM TRIPPE, a citizen or" the United States, residing at Holstein, county of Warren, and State of e Missouri, have invented a new and useful Clamping-Tool, of which the following is a specification.
This invention relates to clamping tools.l n boring wells and the like a part of the boring mechanism or tube sometimes becomes detached from the operating mechanism which is above the groundso that it is often exceedingly difcult and frequently impossible to withdraw or remove the detached part from the well or the like. Devices have been provided for the purpose of engaging and Vwithdrawing the detached part from the well but such devices have been unsuccessful to a large extent, for the reasontliat it is diflicult and in many instances impossible to engage such devlces with the detached parts in the well with sufhcient firmness or rigidity to hold and 1withdraw the detached part from the well.
purposes are cumbersome andV expensive and too easily damaged.y
The object of my present invention is to provide an improved clamping tool to. serve the purposes mentioned and which' is not subject to the objections stated; so that when the device is lowered into the well it will with certainty efiect firm and rigid engagement with the detached part of the boring mechanism or machine and will hold such enga ement. when the tool Ais withdrawn, there y withdrawin the detached part from thewell so that the oring may be'continued 4in the saine well. 40 In the accompanying drawings, Figure 1 is a side elevation of my l-nnroved clamping tool in position in which it is about to be engaged with a section of tube or pipe.
Fig. 2 is a vertical sectional view illus trating the gripping devices -engaging the tube or pipe. Fig. 3 is a cross sectional view illustrating \the positions of the gripping elements be- 50 fore they have effected rigid and firm engagement with the tube or pipe.
Fig. 4 is a similar view illustrating the gripping elements in firm engagement with the tube or pipe.
As illustrated the device includes a sleeve Specification of Letters Patent.
Moreover, the devices now in use :for such Patented May 7, 1918.
Application led December 24, 1917. Serial No. 208,540.
1 which is Haring toward its lower end.
,The sleeve'l is in connection with a frame Vcomprising thetwo side arms 2 which are connected at their upper extremities with a ring or loop 3 with which the supporting cable 4 may be connected.
'The sleeve l is provided with a number of I and rigid grip will be effected` in order to l enable the gripping tool to retain its connection with the tube or pipe and withdraw the saine from the well. Each of the cam disks has a projection 9, which projections are arranged to engage or contact with the sleeve 1 above and below the ends of the slots 5 in which the cam disks operate. yThus each cam vdisk is permitted to turn about half of a` revolution, the extent of turning movement of the cam disks being limited by the projections 9.
In operation when any part of the boring mechanism in the well has become detached or broken from the operating mechanism, the ipping tool being in connection with a su ciently strong cable is lowered into the well until the upper end of the detached part of the boring mechanism .is received or extended into the sleeve 1. As the sleeve is lowered around the broken or detached part of the boring mechanism the teeth or ser'- rations on the cam disks 7 contact therewith,
but do not effect firm or rigid engagement with the detached part until the sleeve has lowered a sufficient',v distance to receive the upper portion of said detached part. It can readily be ascertained whether the gripping toolhas been lowered far enough, simply by pulling on the cable; because if the upper portion of the broken or detached part is Within the sleeve 1 any upward movement of said sleeve will cause the cam disks 7 to turn toward the positions illustrated in4 Fig. 2 and firmly grip the broken part as shown. This gri ping engagement is firmly positive and rigi so that by winding u the cable the detached or broken part o the boring mechanism will be withdrawn from the well after which the well may be bored Aet 'to a greater depth if desired, or finished Without leaving therein the broken part of the boring machine. v
A gripping tool of this construction is very strong and maybe economically manuactured. It entirely dispenses With the use of springs and similar objectionable actuating devices for effecting engagementivith the broken part in the Well. My "invention utilizes as the gripping elements the strong cam disks strongly supported so that when the gripping engagement is e'ected it is rigid and unyielding.
It Will be apparent that the number of the cam disks may be varied and that there may be various other modifications Without departure from the principle and nature of the invention.
l/Vhat l claim is 1. A clamping tool of the character described, comprising a sleeve arranged to encircle a detached part of a boring machine, and having slots near one end thereof, an eccentric cam disk supported in each of said slots, and a projection on each of said cam disks arranged to engage against the sleeve at the lower end of the slot When the cam disk is in that position which it occupies when the portion thereof having the shorter radius is toward the axis of the sleeve and arranged to vengage against the sleeve above the slot to limit turning movemetff the cam disk.
2. A clamping tool of the character de scribed, comprising a sleeve arranged to encircle a detached part of a boring machine and having slots near one end thereof, an eccentric cam disk supported for turning movement in each of said slots from a position in which the portion having the shorter radius is toward the axis of the sleeve to a position in whichy the portion having a larger radius is toward the axis of the sleeve, and a projection on each of said cam disks arranged to engage against the sleeve at the upper end of the slot to limit turning movement of the cam disk when the portion of the cam disk having the longer radius is toward the axis of the sleeve.
3. A clamping tool of the character described, comprising a sleeve arranged to encircle a detached part of a boring machine, andhaving slots near one end thereof, an eccentric cam disk supported in each of said slots in such position that the portion having the shorter radius extends inwardly beyond the plane of the inner surface of the sleeve, a projection on each of said cam disks arranged to engage against the sleeve at the lower end of the slot 4When the cam disk is in that position Which it occupies when the portion thereof having the shorter radius is toward .the axis of the sleeve and arranged to engage against the sleeve above the slot to limit turning movement of the cam disk, and serrations on the peripheries ofthe cam disks arranged to engage the detached part ot the boring machine With pressure increasing according to the increase in power applied to the clamping tool and the resistance of the detached part.
