TWISTING-TOOL.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed March 31, 1920. Serial No. 370,233.

T 0 all whom it may concern:

Be it known that 1., JOHN SCHNEIDER, a citizen of the United States, and a resident of Elizabeth, in the county of Union and State of New Jersey, have invented a new and Improved Twisting-Tool, of which the following is a full, clear, and exact ClGSCI-1P tion.

This invention relates to splicing and twisting'tools, and more particularly relates to improvements in tools generally used for splicing wires or strands, such as electrical transmission lines.

An object of the invention is to produce a new and improved twisting tool having special facilities for rendering the tool can pable of use on splicing work where varlous-sized splicin sleeves and strands are necessarily employed. And it is also an object to produce a tool having improved and convenient clamping means for mounting the device on parts to be twisted.

Furthermore, it is an additional object to produce an improved twistingtool which is capable of being quickly mountedin working and twisting position on wires to be formed into a spliced joint, andalso which will be convenient and easy to remove therefrom after the twisting of the wires has been completed.

While I am aware that twisting tools have heretofore been made and used, what I claim for my invention is the improved adaptability of a twisting tool of this character which may be used on splicing sleeves and wires of various sizes so as to avoid equipping and encumbering linemen with a multiplicity of twisting tools. The particular facility with which my tool is mounted upon the work and removed therefrom without the necessity of taking the tool apart is another feature of my invention-which I claim as new and within the scope of this invention. I

Having the above principal objects in view, the invention has relation to the construction and arrangement of tool parts, an example of which is set forth in the claims defining this invention, described in the following specification, and illustrated in the accompanying drawings, wherein Figure 1! ShOWS a splicing s eeve and stranded wires or cables contained in the sleeve made ready to be acted on by the tool, and Fig. 2 shows the splicing sleeves wlth the wires therein in finally twisted and completed shape to produce a spliced joint.

Fig. 3 is a sectional view taken on the line 33 of Fig. l, and Fig. i is a view taken on the sectional line iri of Fig. 2.. These vlews are exhibited in the drawing to more comprehensively disclose the utility of a twisting tool.

Fig. 5 shows the twisting tool in side ele vation, and Fig. dis a view of the tool shown from a direction right angular to the position of Fig. 5.

Fig. 7 is another side elevation of the ool, with the handles thereof broken away, to show a position of the parts reversed as compared to the other views of the tool, whereby a twisting socketor opening is obtained for use on line work where large and heavy splices are made.

Fig. 8 is a fragmentary View of the twisting head of the tool to show elongated openings in the twisting heads for the purpose of rendering the tool convenient in the application to and removal from the work.

In presenting a'more comprehensive disclosure of the invention, there is shown in the drawings a handle bar 10 having a head 11. The head is provided with holes therethrough for the reception of clamp bolts. The bar is made with a number of semioval'depressions or socket ovals 12 in the opposite faces or surfaces of the bar, and these depressions are rounded off on each outer edge to impress a gradual winding and twisting force against the splicing sleeve used in making joints. The handle of the bar may bemade any appropriate length and size, and the head is preferably made rectangular in cross section to accommodate the holes forthe clamp bolts and the depressions 12. The above description covers the general design and construction of one of the tool parts, and it is noteworthy that the twisting tool in completed form is a simple combination of two of the aforesaid tool parts.

A pair of tool parts are placed together with the head ends 11 and depressions 12 in registry, whereupon the clamp bolts are inserted through the elongated openings 16 to anchor the parts together. A handle nut 14: is threaded to screw upon the clamp bolts 15, and thereby securely anchor the tool parts together. When the two similar tool parts are anchored together, the resulting device provides a twisting tool of convenient size and having appropriate length to produce sufiicient leverage to wind up or twist the splicing sleeves.

A feature of the tool relates to the elongated openings made in the head, one of the openings 16 of which is made by slotting the outer end of one head 11; while the other tool part is provided with a similar opening 19 which is somewhat longer than the slot 16. A clamping bolt 15 is confined in the registering slots 16 and 19, and when tightened up with the handle nut 14, remains in anchored position to hold the two 7 heads 11 together. However, by loosening the handle nut 14, the bolt 15 may be slipped out of registry with the slot 16, whereupon the two heads 11 may be pivoted upon the other clamp bolt. This action opens up the tool and permits the work, previously clamped therebetween, to be removed from the socket ovals 12. This arrangement of the clamp bolt 15 with the openings 16 and 19 made in the adjacent tool heads 11 greatly expedites the use of the tool in that workmen do not have to removethe two clamp bolts 15 which hold the twisting tool together.

Another feature of the twisting tool resides in the particular design and construction of the semi-oval depressions 12 made in opposite faces of each tool head. It is practical to provide a plurality of socket ovals or sleeve sockets 12 in the tool, inasmuch as one tool may then be used for a number of different-sized splicing sleeves. It is to 'be understood that in practice, any size of socket ovals or sleeve sockets 12 may be formed in the head of the tool. pleted socket oval is defined by the juncture of the two semi-ovals made in the adjacent tool heads 11.

In Fig. 5, the adjustment of the two tool heads is such as to make the smaller sleeve sockets fall within the center of the head, whereby the twisting tool is made ready for use in connection with small and lightweight splicing sleeves; while in Fig. 7, the reverse adjustment of the tool is shown, which adapts thetool for use on large and heavy splicing sleeves. The tool is changed from one position tothe other by removing the handle nuts 14 and reassembling the tool in reverse position. 7 r

To those skilled in the art, suchas linemen, the use of the tool is apparent; but in its application, it is to be noted that the two ends 17 of wires to be spliced are slipped into position within a spliced sleeve or tube A com-.

18. The proper sleeve oval is then selected and a tool mounted in position on each end of the straight splicing sleeve 18. A lineman or mechanic mans each. tool and subjects them to opposite rotation, whereupon the splicing sleeve 18 is given a number of turns to produce a twisted spliced joint, as shown in Fig. 2.

The use of this tool is convenient and effective and facilitates the formation of positive and well-formed spliced joints.

Having thus described my invention, I desire to claim and secure by Letters Patent:

1. A twisting tool having separable heads to engage a splicing sleeve and wire strands to be joined, and having a pair of clamping bolts to hold the heads together; said tool being formed with an elongated opening for the purpose of permitting one of the clamp ing bolts to be shifted out of registry with one of the heads to facilitate the application and removal of a twisting tool from the work, and a plurality of various-sized semioval shaped depressions'made in the separable heads whereby socket ovals of selected size can be formed to adapt; the tool for use on splicing sleeves of various sizes.

2. A tool for twisting a sleeved electric wire joint comprisinga pair of sections, each section being formedwith a handle and a head, each head being formed with sleeve receiving notches on diametrically opposite faces, a bolt extending through. the bolt receiving openings of said head for pivotally connecting the heads together, onev of said heads being provided with a slot in one end and the other of said heads being provided with a notch in one end, said slot and said notch being substantially alined when the tool is in operativeposition, and a clamping bolt extending through said alined notch and slot.

3. A tool for twisting a sleeved electric wire oint comprising a pair of sections, each section being formed with a head having sleeve receiving notches, on diametrically opposite sides in one end of one of said heads, and a bolt receiving notch in one end of the other head, means for pivoting said heads together so. that certain of said sleeve receiving notcheswill register, and a clamping bolt extending through said'slot and'said notchwhereby the elamping'bolts may be said notch and said slot being of substantially the same length and reglstering when the sleeves are in operative position, means for pivotally connecting said sleeves together, and a clamping bolt extending through said slot and said notch for clamping the heads together, said bolt being movable bodily along said slot and notch in a direction longitudinally of the heads so as to become disengaged from the head carrying the notch whereby the heads may be swung to an open position.
