18 Claims.

This invention relates to improvements in the end-block for a hatch tent of the character illustrated and described in my pending application for Letters Patent of the United States led August 10, 1936, Ser.,No 95,112, which character of tent, more especially, is one having a ridge slot accommodating the travel of the fall-line in the load-handling movement of the same, the slot having a cable extending as a liner along its side margins and at the rear terminus of the slot being clamped to the end-block.

As its principal object the present invention aims to perfect the end-block, particularly in the manner of attaching the cable thereto, such as to preclude a. crimping of the cable as the same is flexed laterally under the pressure influence of the fall line.

It is a further and a particular object to provide an end-block which, through its advanced design and an elimination of abrupt bends in the flexed cable, minimizes wear on the fall line.

It is a still further and a particular object, considering the blocks added function of a coupling to connect a suspension line to the cable and also to the reinforcing ropes of the tent, to provide certain advancements serving to augment the coupling function by accommodating the attachment of guy ropes for localizing the tent in relation to the hatch,

Other objects and advantages, with the foregoing, will appear in the course of the following description and claims.

The invention consists in the novel construction and in the adaptation and combination of parts of which a preferred embodiment is illustrated in the drawings and which is hereinafter described and claimed.

In said drawings:

`Figure 1 is atop plan view of an end-block constructed in accordance with the present invention and illustrating, fragmentarily, in the manner of their attachment to the block, the slotreinforcing cable, the multiple ropes which reinforce the tent, and the guy and stay lines which extend laterally and rearwardly 'from the block.

Fig. 2 is a transverse vertical sec-tion on line 2-2 of Fig. 1.

Fig. 3 is a side elevation of the block with the several rigging ropes applied, excepting only the guy lines which are deleted for clarity in illus@ tration. Comparing this view with Fig. 1 it will be noted thatthe suspension line, likewise for clarity in illustration, is deleted from the latter view. l

' Figs. 4 and 5 are enlarged transverse vertical sections taken, respectively, on lines 4--4 and s-s of Fie. 1.

Considering the tent proper (not illustrated), it may be here stated that the same is or may be comprised of a triangular back wall and tetragonal inclined side walls which, at the top or apex of the tent, are spaced apart to produce ay longitudinally extending ridge slot. A cable lines the marginal edges of the slot and is seized at spaced intervals of its length by clamps to connect the same with, the tent walls. In the preferred application, these wear strips for the slot are provided by a single length of cable which at its mid-length is turned about and clamped to the end-block. In the drawings my improved end-block is indicated generally by the numeral I0, and the cable by 6. As general practice in rigging the tent a suspension line, indicated by .1, and a plurality of tent ropes, as 8 and 9, connect with the end-block, the tent ropes lying interiorly of the tent walls and leading from the block to the lower rear and to the lower front corners of the tent. While of no moment to the `present improvements and therefore not illustrated, the forward ends of the cable terminate `at or proximate to the forward limits of the tent whereat the same connect with clews or the like, the clews being suspended from a boom arm of the vessel and additionally connecting with tent ropes which are carried along the forward edge of each side wall to the lower front corners.

The end-block l0, as with the block illustrated and described in my prior application, is of U- shaped plan coniiguration to form a throat describing a continuation of the ridge slot, and fitting in the closed end of this throat is a sheave Il functioning to prevent chang of the fall line (not shown) as the latter is carried to the rear-end limits of the block. At the forward or admission Vend of the throat, my present block is characterized by lead-in shoes |2--l 3 hingedly connecting, as at I4, with the block proper and having a curvilinear divergency, one shoe as respects the other, sufcient to carry the free ends laterally beyond the normal planes occupied by the cable. These curving free ends ofthe shoes @are furCate, producing cable seats which conmovement through the instrumentality of saddling the same for slippage with bolt-clips I6, one of these clips being applied over the cable in proximity of the root end of a shoe and being complemented, on the shoe itself, by one or more clips. The cable clamps, which is to say the caps I5, are employed in pairs and joined by an integral strap ll acting as a -bridle to receive a shacklel', these shackles, one at each side of the bloclconnecting with guy 'ropes I9 'which extend laterally and are secured to deck cleats for holding the block against side movement Further characterizing my block and projected rearwardly therefrom above the bight of the cable is an integral extensionV 20 tted with: shackles Ill-22. The former yof `these shackles connects with the eye of the suspension line 1,' which said line carries through a boom-carried pulley block and thence to a deck cleat, and the other shackle 22 functions to engage a back stay 23 acting complementary to the guy ropes I9 in that it holds the block against forwardV movement. Also formed at the rear end of the block as an integral part of the same, but lying below the cable-receiving groove, are laterally spaced ears Z-25 through which is passed a transverse bolt .21, this bolt acting to engagethe terminal loops of thetent-reinforcing ropes 8 and 9.

It is believed that the described end-block will be clearly understood withoutfurther reference to its employment on a hatch tent, particularly so considering that theV handling of cargo through the ridge slot of a tent of the character described is now common practice.

I intend, in the interpretation of the language used, that the hereto annexed claims be given a scope commensurate with the degree to which my improvements are a functional advance in` the art.
