This invention relates to improvements in line tightening devices and pertains particularly to a device designed for tighteningguy wires and all other types of wires or lines which connect two 5 bodies together. a 1

The primary object of the present invention is to provide a line tightener which is of simple design and inexpensive to manufacture and which may be easily rrianipula'ted to draw a line into tight condition and secure it in such condition.

Another object of the invention is to provide a wire: line tightener having novel means for assembly on or about the line to be tightened and having novelmeans for securing the assembled parts together after the tightening process has been completed'.

A still further object of the invention is to provide a novel two-part wire line tightener having novel means for actuating it, which means openates to prevent the separation of the parts until the desired degree of line tension has been obtained and certain securing elements have been appliedxfor holding the partspermanently t'o gether. Still another object of theinventionis to pro vide meansfor coupling a guy 'wirewith a ground anchor andfor drawing and securing'the guywirje tightbetween the ground anchor and the body towhich itis attached.

The invention will be best understood from a consideration of the following detailed descrip tion taken in connection with: the accompanying drawingsformin'g part of this specification, with the understanding, however, that the invention is not" confined to any strict conformity with the showing of the drawings but may be i changed or modified so long assuch changes-or modifications markno material departure from the salient features of the invention as expressedin the an- 40 pended claims',

Referring to the drawings wherein like numeral-sof reference designate corresponding parts throughout the s'evera l" views, the numeral 1 indicatesgenerally one form of the device embodying the present invention. In this form of the invention, there are'provided the two disk members 2 and 3, each of which has formed integrally therewith and upon one face the cen trally located nut 4'. In the opposite face of eachof the disksfro'in the nuts 4, there is formed the pair of circular recesses of countersunkopenings 5, the edges of Which-merge, as is illustrated in Figure 2'; Passing througheach disk and through the nut 4 thereof from each of the rec'e'ss'es 5 is a passageor aperturefi and secured inone of the'se apertures ofeach disk is one re duced endortrumiibnt which forms an integral end extension ofa flanged spool 8, the flange of the spool being" positioned in the recess. A similar trunnion is formed at the opposite end of each spool'and is freely insertible into and removable from theeth'er aperture 6 of the opposed plate; Each of the plates, therefore, carries a spool and removably'receives a trunnion of thesp'ool or the other plate. i

The flangesof the spools 8 are located in the recesses-5 of the' plate's so that the out out central area of each spool coincidesii'n width with the dlstancebetween the two plates when the Smears in assembled-[relation and the area between th'e SpoOlsisof-SufliCient si'ze to receive the line or cablewhich'ifs tobe tightened up by the device] I In order tin-facilitate the ready assembling of the plates and spools, a" portion of the flange of each spool is cut away; as indicated. at 9, so that after assembly, the" cable will be snugly held between-thespool si- The'se out" out portions 9' of the spools are each in opposedrelatio'n to the flange of the other spoolas will be readily seen upon an inspection of Figure 1. w

Each of the plates 2 anjd 3 is p'rovided with a series of apertures 10" about and adjacent its edge, for the reception of bolts 11 after the devicehas been manipulated ii -the manner hereinafter described to efiectthe tightening of a wire-line; I yrua eemtio of the device is efiected by meanest the two-jawed wrench which is in'- dicated generally by the numeral 12 and which comprises the handle portion 13 and the bifurcated ends 14, each of which terminates in the open jaw 15. The space between the furcations 14 of the wrench is sufficient to snugly receive the two disks 2 and 3 when the latter have been assembled, so that each of the jaws 15 may engage with the nut 4.

In the operation of the tightener, the same is assembled on the wiresuch as that indicated by the numeral 16 by bringing the disks 2 and 3 together from opposite sides of the wire so as to insert the free end of each spool 8 into an aperture of the opposite disk and thus locate the wire in the space between the spools.-The wrench is then applied in the manner described and manipulated to rotate the disks so that the wire line or cable will be wound 'up'about the two spools. After the desired degree of tightness has been attained, the bolts 11 are inserted in the appropriate apertures 10 to connect between the disks at the peripheries thereof and to extend across opposite sides of the line. These bolts prevent the separation of the disks and also, because of the fact that the wire line extends across them, prevents the line from becoming unwound from the spools. Y

It will be observed that in the process of winding up the line, the furcations 14 of the wrench prevent the separation of the disks 2 and 3, and this duty is passedonto the bolts 11 after the wrench has been removed. H i

In Figures 5 and 6, there is illustrated a modified form of the tightener just described in which the parts are integral. 1 In this form, it is necessary that the wire, which isto be tightened, be threaded through the tightener before it is connected between the bodies which. it is to join together. In this form of the invention, the disks 17 are joined by the two spaced bodies 18, the area 19 between whichis formed in cross section to snugly receive a cable and the outer surfaces of these bodies are transversely rounded, as indicated at 20, so as to form together a circular bearing surface-on which the wire line or cable may be wound up. u

The outer faces of the disk 17 have the nuts 21 integral therewith for the reception of the jaws of the wrench 12 and the disks adjacent their peripheries are provided with the plurality of openings 22 for the reception of connecting or coupling bolts such as those illustrated in connection with form 1, to hold the line after it has been wound up.

In Figures '7, 8 and 9, there is illustrated the form of the invention designed. for tightly connecting a guy wire with a ground anchor, In this form, the wind up device is indicated generally by the numeral 23, and comprises a solid hub 24 about which are formed the disks 25.

These disks 25 are provided with the peripheral series of apertures 26 and the hub is provided with a central transverse aperture 27 in which the end of the guy wire is inserted and where it is securely held by the binding screw 28 which is tapped into the opening formed from one end and axially of the hub.

The hub 24 is circular in cross section and has its ends received in the rings 29 of a pair of links 30. These links are connected at their outer ends by a bolt 31, which also passes through the apertured end or yoke portion 32 of the ground anchor 33. This yoke end 32 of the ground anchor is disposed between the links 30, as illustrated. Intermediate its ends, the links 30 are provided with the short longitudinally extending slots 34 which are positioned to aline with the apertures 26 of the disks 25 so as to receive the securing or looking bolt 35 when the desired degree of guy wire tension has been attained.

The wrench member designed for rotating the take-up device 23 is indicated as a whole by the numeral 36, and comprises a handle 37 and the bifurcated end 38, the portions of which are bent or arcuately formed to coincide with the curve of the hub 24. The bifurcated end of the wrench 36 straddles the disks 25 so that the curved portions thereof will rest against the rounded surface of the hub, and a bolt 39 is then passed through apertures in the furcations and through the apertures 26 of the disks so that the rotation V of the disks may be then effected by pulling upon the wrench handle 37. After the proper degree of tension is attained, the bolt 35 is extended through the apertures 34 of the links and the apertures 25 of thedisks which are ,in proper position, so as to lock the links and the disks together and prevent unwinding of the'cable.

It will be apparent that in the tightening of the cable, which is here indicated by the numeral 40, the hub 24 of the tightener willturn in the rings 29 of the links.

From the foregoing, it will be readily apparent that devices as herein described are of a relatively simple character and may, therefore, be inexi pensively manufactured and at the same time, they are so designed as to withstand the heaviest strains which might be imposed upon devices designed for the purpose described.
