Application filed September 9,1914. Serial a... 860,922.

To all whom/it may concern: I 1 7 Be it known that I, ANsLEY BARNES, a citizen of the United States, residing at Waterville, in the county of Kennebec and State of Maine, have invented new and useful Improvements in Gable-Tighteners, of which the following is a specification.

This invention relates to cable tighteners, and it has particular reference to an improved device by means of which cables and Wires such as the guy wires of telegraph and telephone poles and the like may be quickly tightened and placed under high tension without the use of the ropes and tackle ordinarily employed for this purpose.

A further object of the invention is to produce a tool of simple and improved construction for the purposes set forth which may be readily collapsed and packed in small compass for carriage from place to place.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,-Figure 1 is a side elevation of a tool constructed in accordance with the invention. Fig. 2 is a sectional detail view taken on the line 22 in Fig. 1. Fig. 3 is a sectional detail view taken on the line 33 in Fig. 1.

Corresponding parts in the several figures are denoted by like characters of reference.

. The body of the improved tool consists of a strip 15 of steel or other suitable material having at one end a longitudinal slot 17. Pivoted on a bolt 18 which slidably engages the slot 17 is a bar 19, one end of which is bifurcated to produce ears or lugs 20 through which the bolt or pivot member 18 extends, the bifurcated end of the bar 19 being placed astride the body member 15. The top edge of the latter is provided with ratchet teeth 21 that are engaged by a pawl teeth. The

- 22 pivoted between the ears 20 on a bolt or pivot member 23. A spring 2 1 is arranged to engage the pawl 22 and to sustain the latter in engaging or non-engaging position with respect engaging position being indicated in dotted lines in Fig. 1 of the drawing; the pawl being provided with two flat faces 25 and 26, substantially at right angles to each other, either of which may be engaged by the spring. The bar 19 is provided in its under edge with a plurality of teeth 27 and with notches or recesses 28 intermediate said bolt or pivot member 18 supports a link or clevis 29.

A bifurcated lever 30 is fulcrumed on a pin or bolt 31 that extends through the body member 15 intermediate the slot 17 and the hook 16. The limbs of the lever 30 are connected by 'a transverse pin 32 adapted to engage the recesses 28 between the teeth 27' of the bar 19.

In operation, the cable or guy wire that is to be stretched is connected directly or by grip devices of well known construction with the hook 16, the link or clevis 29 being made fast to some fixed point, after which, by rocking or manipulating the lever 30, the bolt 18 carrying the bar 19 will be gradually drawn along the slot 17, the pawl 22 engaging the teeth 21 to prevent retrograde movement until the desired tension has been attained, after which the cable that has been tightened is made fast in the customary manner. The parts may then be disassembled by releasing the pawl 22 from engagement with the teeth 21.

Having thus described the invention what is claimed as new, is

V 1. In a device of the class described, a body member having a hook at one end, a longitudinal slot at the other end, and a toothed upper edge, a member slidably engaging the slot, a bar pivotally engaging the slidable member, a spring actuated pawl pivoted on the bar and engaging the toothed edge of the body member, and a lever fulcrumed on the body member intermediate the hooked end and the slot and having means engaging the bar to impart a step by step movement thereto.

2. In a device of the class described, a body member having a hook at one end and a longitudinal slot at the other end, a bolt slidable in the longitudinal slot, a bar having a bifurcated end straddling the body to the ratchet teeth 21, the nonmember and forming ears that are pivoted with recesses intermediate said teeth to be on the bolt, a spring actuated pawl pivoted engaged by said pin. 10 between the ears and engaging the toothed In testimony whereof I afiix my signature edge of the body member, a bifurcated lever V in presence of two witnesses.
