As. shown, `this ridge-pole is extended .longitudinally and centrally of the body and consists of a plurality of sections lwhich are collapsible or extensibly I by disconnecting the ropes 36 from the‘cleats 3l so as to release the side and end naps 33 and 34 y for movement from. the positions in which they Vare tied down andheld against the sides and 60 back of the body and the nap 34 may be folded Vor thrown forwardlywith the Vback end of the tarpaulin so as to lay thereon, such as forwardly of the rear cross bow 42.

These cables as well as the cables forming the guides 52 may be three-sixteenth inch cables or otherwise. One end of each cable is extended around a vertically journaled guide pulley ‘ll in the rear of each winch and then horizontal outwardly under a horizontally jour naled guide pulley l2 suitably supported by the body or frame substantially beneath the hollow sides i3 and then upwardly through the latter between the inner and outer walls thereof, through suitable holes 'i3 provided in the side frames lil. These cables are then extended horizontally over guide pulleys lfîl and then horizontal rearwardly to the rear corner posts or other suitable vertical frame members, where they are extended around guide pulleys ‘l5 and then upwardly near the rear end of the body over guide pulleys ‘le supported beneath the roof 24 constituting the solid or per manent portion of the roof of the vehicle body. During this movement, the cables will freely slide through the bows and this will also be the case i when the top is closed or extended rearwardly to cover the open top of the body. To do this, it is simply necessary to turn the crank and shaft to the right or in the opposite direction to oppositely wind and unwind cables so as to pullrearwardly on the rear cross bow which will successively space the cross bows and extend the cover to the rear of the body in the reverse order from that in which said parts move when the top is opened as heretofore explained. When so extended, the tarpaulin may be tieddown by drawing the llaps 33 and 3e together and tightly over the top of the body by the ropes S53 and anchored to the cleats 3l' so as to positively retain the tarpaulin on the top rails Iâ rearwardly of the rear cross tight whereby the body is maintained weather bow when extended and to which the end of the cable is anchored as by suitable take upV means 20 tight to protectV the contents thereof. Obviously when the tarpaulin or cover is opened and closed consisting oi a turnbucklecor eyebolt ll bolted in the manner described, it will move along the through the rear cross bow and held by a nut guide members or cables 52 at the sides of the threaded thereon for adjustment so that any slack body by being slidably connected therewith and in the cable may betaken up to maintain the held down during such movements to retain its cables taut. The other ends of the cables are smooth condition-to facilitate same by reason of extended forwardly of the Winches around verti the loops or snaps 54 engaging the guide members cally journaled guide pulleys ’i8 also journaled in or cables 52 at such points beneath the side flaps the frame beneath the flooring and then out or overhanging portions 33.- The extensible ridge lâ* beneath the hollow sides i3 of the body.- from 30 pole will automatically collapse or telescope when the top is opened to be similarly extended when which points, the cables are extended vertically the top is closed by reason of the sections thereof npwardly over guide pulleys 8b also mounted being connected at their Yrear ends to certain of on the top rails is. Fromthispoint, thecables the cross bows in the manner described, and will extend rearwardly through the cross bows ¿l2 beneath the top or tarpaulin Sii and preferably 35 also help to support and sustain the tarpaulin Vinstead of permitting the same to drop down at in the space within the brackets or end members i the center beneath the cross bows either in open 63 between the top portions ¿l5 and the rollers or closed position and also facilitate draining of upon which they may rest and move freelyV wardly under horizontally journaled guide >pulleys w. i the rotation of the rollers. The rear ex tremities of these end portions of the cables are connected to the rear cross bow in the same man the top or roof of the body. Aside from the per manent orY solid roofy portion 2li, the device may be economically produced and applied initially to trailer or other truck bodies, or to those hereto fore constructed for modiñcation in accordance ner the opposite ends by take up devices con sistine of adjustableeyebolts or turnbuckles ex tended irom the opposite sides or faces of said cross bow but for the same purpose, namely to take up slack in the cables and maintain the with the present invention. same taut. As will be noted from Figs. 1, 3, 6 and '7 of the drawings, the'pulleys ‘l5 and 89 are lo cated beyond but adjacent to the'ends of the top and bottom of the body at the back and the While any suitable means may be employed for fastening the rear doors 253, the fastener or bolt ing means 22 is shown engaging keepers at the doors terminate at the top below the rear or tail angle bars or rails @d and may serve as means for ñap 3A beneath which and at the top of the body limiting the movements of the cross bows and cover ofthe top to4 extended or collapsed posi tions. in operating the device, the crank E3 is applied to the end @l of the shaft Gil and by turn is provided, anchored by means of removable pins 82 at the ends engaging interñtting hinge loops or eyes 63 carried by the endsof the header and ing the crank and shaft to`th'e left as seen in Fig. 3, the cables l@ which extend over the top rails and tracks and onto the Winches iidfrorn the guido pulleys le, are wound on the winches while the other portions leading over the guide pulleys li are unwound, thus moving the rear cross bow di: forwardly until it engages the next cross bow forwardly thereof and then the next cross bow and so on until all of the cross bows have been moved forwardly to the rear cross bow or trans verse bar 25a of the roof 24 to collapsed position so as to uncover the top of the body. The top is thus opened and will result in the tarpaulin being drawn to the forward portion of the open top oi the body and the portions oi the tarpaulin be tween the ribs will close in bellows-like fashion and~ drop in folds over the ridge-pole As the cro ‘news move forwardly, the section Ei‘Z of the ridge-pole will move into tubular section äil and these two telescoped sectionswill then move into the housing section 51 which is held stationary at the back a solidv or one piece rear header 8i the rear ends of the sides at the rear corner posts d so that when the rear or tail nap 345 is raised or the top is open, a pin may be removed from either end of the rear header so that it may be swung open horizontally on its hinge or pivot to either side so that the entire back of the body is open and unobstructed when the doors are opened. Of course, since the doors 20 do not extend as high as the lower edge of the rear or tail nap all, the doors may be opened at any time by unbolt ing the fastener 2 l, withoutdisturbing the rear or tail nap. y While ïV have illustrated and described the pre ferred form of construction for carrying my in vention into eífect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth but desire to avail myself of such Varia tions and modifications as come `within the scope of the appended claims. 2,406,737 10 9 Having thus described my invention, what I cables, a transverse shaft suitably journaled ad jacent the bottom of the body, drums on said shaft on which said cables are wound in opposite directions and means for turning the shaft to cover and uncover the body. an open top, sides extending to the top of the 4.
