Jan I931. ALLEN LATCH SHAGKLE *Filed on'ia, 8. 1927 INVENTOR.
Patented Jan. 6,1931
- UNITED STATES EDGAR ALLEN, or WIcIirrA FALLS; LATCH snAcxLE I I Application filed October 8,1927.
This invention relates to new and useful improvements in a latch shackle.
One object of the invention is to provide a connecting shackle of the character de- 5 scribed whereby a traveling block bail,b a1ler bail, and the like, may be connected to a rope or cable socket in such manner that'the connected parts will not come into contact, or become injured when the line, carrying said rope socket, is permitted to slack, or from other causes.
Another object of the invention is to provide a shackle of the character described,
which is very strong and durable and which has no projecting parts to hang, or become broken in going into or coming out of the well bore, when the shackle is used in well drilling 0 erations.
A urther feature of the invention is to provide a novel form of latch, or latching tool, whereby the shackle may be readlly connectcd to and disconnected from the cable socket.
With the above and other objects inview this invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, where- Figure 1 shows an elevational view, partly in section, of one form of the shackle.
Figure 2 shows an edge view of a connectinv link employed.
a igure 3 shows an end view of said link.
Figure 4 showsan elevational view of a slightly modified form of the shackle, partly in section and Figure 5 shows a side view of a connecting link employed in this form.
Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the body of the shackle which is formed with the end eyes 2, 2, one to receive the cable socket latch having the eye 3, and-the other to receive the bail 4, of a traveling block, bailer, or the like. The main body of the shackle is of a general elliptical form and between the eyes 2, 2, is
2 Serial no. 225,096. a v r v. thickened inwardly. One side of the shackle 1s removable." In the form'shown in- Figure '1 this removable part comprises a bar 5 whose ends are formed with mortises 6, 6 dovetailed in torm' in which the correspondi-n'glyf shaped tenons 7 7, ofthe abutting parts of the'bo'dy 1 interlock and these interlocking parts are furthersecured together by means of the bolts 8, 8, which are fitted-inwardly through them and whose heads are counter sunk in said bar. The inner ends of these bolts are threadedto receive; the nuts-9, 9, which are also countersunk into the corresponding tenons 7 to the end that the shackle will have no unnecessary projections to cause theshackle' to hang, when in use. The bar 5 has the inwardly extending spaced clamp flanges 10, 10, which embrace the relatively flat inwardly extending tongue 11, into which the inwardly thickened portion of the body 1 is formed. 1 The outer sides ofthe clamp flanges 10, are substantially flush with the-outer side of the adjacent partsof the body-1 to give-the shackle asmooth outside contour and a set screw 12, is fitted through said clamp flanges and tongue withits head countersunk into one of said flangesand its other end threaded into the other clamp flange.
In the form shown in Fi has the dovetailed end mortlses 6' 6 adapted to receive, and. interlock with, the corresponding end tenons 7 7, into which the adjacent parts of the shackle body 1 is formed. These interlocking parts are further secured together by means of setscrews re 4 the bar 5' 8, 8 which are fitted inwardly therethrough and whose heads are countersunk into the bar 5 and whose inner ends are threaded through the tenons 7' 7'.
The bar 5' is thickened inwardly and said through said body 1' and said tenon 107.
This type of shackle also has a comparative:
ly smooth exterior surface.
By the use of the type of shackle hereinabove described the connected parts will be kept apart and will be better protected and consequentlywill not be so subject to wear "or injury." a
While I have shown what I now consider lithe preferred forms of the device it is obvious that mechanical changes and adaptations maybe made. within the scopeofthe app fc a m t a What I claim is 10 "1. A shackle of general elliptical form,
- having end eyes and forinedof-separable complemental parts, one part comprisinga removable side bar whose ends are formed V with mortises, said bar also having, inwardly 15 extending spaced clamp flangesintermediate its-ends-a'nd havinga slot between them,the' other complemental; part having ftenons which fit into said mortises and also having a wide,- relatively flat, inwardly extending m tongue fitted into said slot between said clamp-flanges, bolts securing said tenons in said mortises and a set screw-securing said tongue between said clamp flanges. Y 1
*2. A shackle having end eyes and formed ofsepara-bleicomplemental parts, one part scomprisingna removable side bar and the other partq-liaving-facing, spaced ends, said bar andthe adj acent ends of said other complemental part being formed one with tenons and-the other with'niortises adapted to receive said tenons, means passing through said-'intermeshing parts to, secure said bar in=p1ace said bar and. the other complemental part beingeachextended inwardly and one being formed with-camp flanges, spaced apart to form a slot'between them and the other'with wide, flat, tongue which 'fits in saidseat between said flanges and a securing means passing: through said qflanges and I tongue to secure them together.
