ROPE-CUTTER.

SPEGFICATION forming part of Letters Patent No. 745,523, dated December 1, 1903'.

v Application dled September 23, 1903. Serial No. 174,266\ (No model.)

.To nel?,l whom it may concern:

Be it known that I, THOMAS C. ROGERS, a residentof Sistersville,in the county of Tyler and State of West Virginia, have invented a 5 new and useful Improvement in Rope-Cut'- ters; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to rope-cutters, and has special reference to such a device as 1o would be used in connection with the drilling of Artesian wells where a wire rope is used in such drilling.

The object of my invention is to provide a cheap, simple,and edective rope-cutter which x 5 will insure the placing of a portion of the wire or other rope insuch a position that it will be out or severed in a rapid and easy manner and at the same time permit the device to be easily and quickly connected zo around and Withdrawn from the rope.

My invention consists, generally stated, in the novel arrangement, construction, and combination of parts, as hereinafter more specically set forth and described, and par- 2 5 ticularly pointed out in the claims. Y

T0 enable others skilled in the art to which my invention appertains to construct and use Y my improved rope-cutter, I will describe the same more fully, referring to the accompany- 5o ing drawings, inrwhich- Figure 1 is a sectional view of an Artesian well, showing the wire rope thereon and my improved cutter around the same. Fig. 2 is an enlarged vertical section of the cutter in 35 position for operating upon the rope. Fig. 3

is a top view of the cutter. Fig. 4 is a crosssection of the same on the line 4 4, Fig. 2; and Fig. 5 is an inverted cross-section on the line 4 4, Fig. 2, showing a face or bottom view of 4o the knife employed.

Like letters or symbols of reference herein indicate like parts in each of the figures of the drawings.

As illustrated in the drawings, A represents 45 the well, and within which is the wire rope 1, which passes through the opening 2in the rope-socket 3, and such socket is connected at its lower end to the drilling bit or tool. (Not shown.) The upper face 4 of the rope-socket 5o 3 is provided with the curved recess 5 within the same around the opening 2 therein, and extending around the upper end 6 of the socket 3 is the head 7, which is provided with the hollow portion or chamber 8 therein, having its bottom 9 outwardly daring through 55 the side wall 10 and at the lower end 9' of said head, as at 11. At one side of head 7 is the slot 11, which extends the full length ofthe said head and through the side wall 10 thereof for the passage of the wire rope 1 through 6e the same from the' rope-socket 3, and such rope being heid within said slot 11 by means of the clamp 12, which ie secured upon the upper end face 13 of said head 7, over and around the said slot, by the bolts 13 and is pro- 6 5 vided with the curved seat 14 therein, iitting around said rope l. The upper end of said head 7 is provided with the inwardly-projecting portion or flange 15 above the chamber S, through which extends and is secured there- 7o in by its screw-threads 16 the cutter-bar 16, which is provided with the-outwardlyextending flange 1G thereon for resting against the flange 15, and below which isrthe knife or cutting face 17. This cutting face 17 is of l75 circular shape and is formed of the angular or inclined inner and outer faces 18 18', respectively, which terminate in the apex or point to form the cutting face 17, and extending into the cutter-bar 16 from the inclined 8o inner face 18 is thecurved hollow portion 20.

A tool member 21 is connected at its lower end 23 to the screw-threads 16 on the cutterbar 16, extending through the head 7, and

such member 21 can be more firmly secured 85 and held in place by means of the pin 23 passing through the end 23 and bar 16. The member 2l is connected by the upper end 22 thereof to another tool member 24, and, if desired, other members can be connected in like 9o manner above the member 24.

The use and operation of myim proved ropecutter are as follows: When it is desired to sever or cut the wire rope 1 within the well A for any purpose, the clamp 12 is opened by 95 removing one of the bolts'13 and the rope 1, placed within the slot 11 of the head 7, after which the clamp 12 can be replaced upon said head by screwing down said bolt, which will hold the rope in place in the seat 14 of said roo clamp, so that it will pass through the same and through the slot 11 and chamber 8 of said head. After this is accomplished the tool member 2l can be connected to the screwthreads 16 on the cutter-bar 16 and the member 24 connected to the end 22 of said member 21 by its socket 24, after which the head 7, with the cutter-bar 16 therein and tool members attached thereto, can be dropped into the well A and lowered therein along the wire rope 1. The momentum acquired by the lowering and dropping of the head 7, bar 16, and members connected thereto, as well as the Weight of the same, will cause the rope 1 to be curved or bent outwardlyfrom the ropesocket 3 as such head approaches in close proximity to said socket 3, and when the lower. end 9 of said head comes adjacent to the upper end 6 of said socket the flared end 11 on said lower end 9 will be drawn over and around said socket 3 by coming in contact with the upper end 6 thereof. As said head 7v thus drops and is drawn around the upper end 6 of said rope-socket 3 said socket will be centered in the well. The upper end thereof will pass into the chamber Sfof said head, which will cause the wire rope 1 to be bent t0 a sufficient angle, as at l', so that the cutting edge 19von the cutting-face 17 of the bar 16 will engage the bent angular portion 1 of said rope 1 and cut or sever said rope at this point during the further lowering or dropping of said head 7. As the wire rope 1 is thus severed or cut the end of the said rope above the rope-socket 3 will be contained with the recess 5 on the top face 4 of said socket and the curved hollow portion 2O within the cutterbar 16, above the cu tting-face 17 thereof, during the continued dropping or lowering of said head 7, and further dropping of said head will be prevented by the containing of end of said rope within the recess 5 and hollow portion 2O or by the cutting edge 19 coming in contact with 'the upper face 4 of the rope-socket 3. In case the rope 1 is not cut or severed by the first dropping of the cutterbar 16 against the bent portion 1 of said rope the head 7 can be raised and dropped again or repeatedly to accomplish the severing or cutting of the rope, and after said rope is severed the portion of the same within the-head 7 and above the portion within the socket 3, together with said head, cutter-bar 16, and attached tool member, can be raised from Within the well.

It will thus be seen that my improved ropecutter will bend the wire rope used in Artesian wells for drilling purposes to an angular position, so as to enable the cutter-bar to sever the same when the tools are lost within the well and fishing is required or when other- Wise needed, and at the lowest possible point within the well, as well as at the closest point of the rope-socket.

The device is strong and durable and con` tains few parts to get out of order, being so arranged as to enable the cutter-bar to be removed easily and quickly for the insertion of a new one in case of injury or breakage and for the sharpening of the same when desired.

It will be evident that my improved ropecutter can be used for the severing of welldrilling ropes formed of other materials than wire as Well as being adapted for use in places other than Artesian wells, and that various changes. in the construct-ion, design, and arrangement of the various parts of the same maybe resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
