My invention relates to hand railings, guard. railings, fences, balustrades, and the like, and more particularly to demountable devices of this type which are adapted to'be readily assembled and set in place for use. I

With the foregoing in view, an object of my invention is to provide an improved device of the class described. 1

A further object is to provide an improved device of the class described which includes means for readily detachably connecting a rail to a pair of posts.

A further object is to provide novel connections between the top rail and the posts and novel connections between the lower rail and the' osts.

A further object is to provide an improved device of the class described which includes an improved baluster or picket for connecting a top and a lower rail. I

A further object is to provide an improved device of the class described, including upper and lower rails, and which comprises an improved baluster or picket together with novel, means for connecting the same between the upper and lower rails.

A further object is to provide an improved baluster or picket comprising a pair of sections, and/or an improved rail comprising a pair of sections, and novel means for connecting the sections together. l

Other objects-and advantages reside in, the particular structure of the invention, combination 7Claims. (01. 256-121) and arrangement'of the several parts thereof, and

will be readily understood by those skilled in the art upon reference to the attached drawing in with the following specification,

connection wherein the invention is shown, described and claimed.

of Figure 5, parts being broken away and shown in longi- Referring specifically to the drawing, wherein like reference characters have been used throughout the several views to designate like parts, and

referring first to the form of invention of Figures 1 to 6, inclusive, l0 designates generally a guard railing according to the invention which includes a pluralityof spaced vertical posts H of any suitable cross-section mounted in any suitable manner in or on any suitable surface. The upper ends of the posts have adapter collars l2 secured thereto for mounting the leg 13 of a T-coupling 14. The runner of the T-coupling M has externally-threaded free ends Hi, the threads of which are similar. Top rails I 6 extend between the free ends of the runners of the T- couplings in aligned end-to-end relation. The top rails l6 have externally-threaded free-ends l'l. As clearly shown in Figure 4, the threaded ends l5 for the runner of the T-coupling M are substantially twice as long as the threaded portion ll on the, free end of each rail [6. As shown, the threads are right-hand threads, but, of course, could be left-hand threads if desired. As clearly seen in Figure 4, the sleeves l8 are at least as long as the combined lengths of the threads l5 and ll of the adjacent ends of the top rail l6 and the runner of the T-coupling [4. Likewise, it should be noted that the bore of sleeve I8 is internally threaded for a major portion of its length, as indicated at l9. In the embodiment shown, thelength of the threaded bore [9 is substantially two-thirds the length of the combined length of the threads ll and I5 when the ends of the top rail and the runner are abutting. Obviously, if the free ends of the rail and runner are slightly separated, the relation of length of the threaded bore 19 will be increased as necessary. .The remainder of the length of the bore of the sleeve I8 is formed to provide an enlarged, unthreaded counterbore 20 which is slidable not only relative to the threaded ends I5 of the cou plings I4, but also relative to the unthreaded portion ofsuch couplings. To connect a top rail [6 in place, when the opposed ends of the runners of adjacent T-couplings I4 are aligned, the sleeve I8 is applied to one threaded end H) of a runner and threaded thereon until the threaded end of the sleeve isflush with the free end of the runner, as clearly shown at the right in Figure 4. Thereafter, an end of the rail 16 is brought into abutment with the corresponding end of the runner of the T-coupling l4 and the sleeve threaded onto the threads I! of the runner to provide a firm threaded coupling. The back threading of the sleeve 18 on the runner is permitted beyond the inner ends of the threads l5 by the counterbore 20 of the sleeve. At the same time, and as clearly shown at the left in Figure 4, when the sleeve is threaded onto the threads I8 of the rail I6, the counterbore 2 overlies and conceals the inner ends of the threads I5. Without such counterbores 2D, the threads I would of necessity have to be of much greater length and a portion thereof would be exposed when the sleeves were threaded onto the threads ll of the rails.

As clearly shown at the right in Figure 1, where the adjacent ends of the T-couplings are aligned on inclined planes, special T-couplings 2I and 22. are provided. Thus, the adjacent or right-hand runner of the T-coupling 2I is downwardly in-e clined at a proper angle of inclination. to, be aligned with the upwardly-inclined adjacent runner of the T-coupling 22. Likewise, when the railing must turn a corner, the T- coupling 22 may be provided with a runner or runners directed at a proper horizontal angle to the remaining runner or arm.

The structure so far described may be used alone as a hand rail without additional lower rails.-

H'owever, ifused as a guard railing, l? prefer'to'.

have one or more loWer rai1s,-nOw to be described.

Referring nowto Figures 2 and 3, it noted that eachpcst II has secured thereto a plue rality of vertically-spacedbosses- 23 in down? wardly-spaced relation to the upper: ends of the posts. Each bossZ'S' is secured to its post i -in any suitable or well known manner. 23' is provided with opposite side surfaces 21, Figure 3, which in the instanceshown are flat, parallel surfaces. rected is secured to the front face of eachbcss 2'3 and is provided with a laterally-elongated hook cavity. Thus, the cavity 27" includes a vertical rear surface 28 comprisingthe forward" face of the boss 23 and a forwardcavity Z-B'below the bill'of the hook. Entrancetothecavity 27 ispro-- vided by; anupper slot 30 for'an eye now to be described.

Where the invention is applied to a fence, either a rail fence or a picket fence, where projections above, the toprail are desired*,' bosses23=- and hooks 25 ma be substituted fo th'e couplings aforesaid and rails'now to be-describedmay' ends of the sideplates or ears 33. Each eye 32 has. the opposite end"thereo-fformed to provide a socket. 36 which is internall threaded for threadedly. engaging the threaded free ends 37 and; 38. of the lower. rails 3 I. In this connection, it should be noted'that the internalthreads of thesocketsstfi arecomplementary to the threaded ends 3-]. and. 3Iand that thev threads 3'! are right.- hand threads, while the threadsfiil are left-hand threads. Thus, each rail'ajl functions asaturnbuckle. in a-well knownmanner. Try-apply lower rail; 31' between adjacent posts I I, the sockets 36 of the eyes. 32, areconnected. to the. opposite ends of the-rail by; partially threading the ame thereon. One-cross-piece 3.5 is'now seatedin one hook 26 against the. rear surface 28.v The crosspiece on; theopposite. eye 32'is.now appliedto. the hook. Z-tomthe opposite post I I, Toproperly Each boss A hookwhich is upwardly di Each side plate 33- is con-- nected by a cross-piece 35' inwardly of the free 4 apply it, it may be necessar to lengthen or shorten the distance between the adjacent eyes by turning the rail 3! relative to such eyes. With both cross-pieces 35 seated in the opposed hooks 26, the rail 3| is twisted in a direction to cause the eyes 32 to move toward each other, whereby to seat the cross-piece 35 in the hook recesses 7. .9, whereby the rail is tensioned into position between the posts II. A reversal of this performance loosens: the lower rail 3i and permits it to be separated from the adjacent posts I I. Relative rotation is prevented by ears 33.

Referring now to Figure '7, the structure there disclosed conforms in certain features to that of the preferred form of the invention, in that it includes a pair of spaced posts I I I having T-couplings Msecured to the upper ends thereof. Top rails H6 are secured between the T-couplings I4 inthemanner previously described b the sleeves I8. In like manner, a lower rail S SI is secured between the postsw I M by: hooks fcrmed on the bosses 23 thereof; However, in: this formofiithe invention, the top rail H6? is provided witha plurality of depending hamsters-5U, the upper ends.

to tighten the connection between the sockets:

in a-manner previously-described. Thestuds 5'1 and balusters 5B are so disposed as to substantially abut in end-to-end aligned relation when the lower ra-il- I3I is rotated so as'to dispose the studs 5i vertically. Such adjacent ends of the studs and hamsters are externally threaded with like threads and are connected'together by sleeves I I 3 corresponding tothe sleeves I-3"previous1y' described. That is to say, one of the free ends of eachpair of adjacent studs and balustersis provided with a longerseriesof: threads than the other, whereby the sleeve may be retracted t'o lie with the sleeves II=8 secured in place, both the top rail H6 and the bottom rail I3l-' are secured against rotation andaga-inst accidental displacement. If desired, the bottomraili3I may be provided with depending studs 52 of a length to just clear the surface of the ground, but thesestuds may be omitted, if desired.

As previously mentioned, the Figure 7' form of the'invention maybe modified by'the substitution. of rails I31 and hooks 26" for the top'rail I16 and couplings M. Also, instead. of balusters 553, pickets of similar structuremay be substituted to. include upper ends projectin'gabovethe top rail. Likewise, ornamental upward projections may be. addedto the tops of theposts I'll.

While I have shown and described what are now considered to be the preferred embodiments of the inventiongit is tobe. understood that the same is susceptible of other. forms. and expressions. Consequently, I do. not limit. myself to the precise structuresshown. and described here.- inabove except as hereinafter claimed.
