ADJUSTABLE SUPPORTS PROVIDING UNIVERSAL MOVEMENT Filed May 17, 1951 2 Sheets-Sheet 2 J 51 INVENTOR. HARRY F. LIVINGSTON A TTORNEY United States Patent ADJUSTABLE SUPPORTS PROVIDING UNIVERSAL MOVEMENT Harry F. Livingston, New York, N. Y. Application May 17, 1951, Serial No. 226,821
Claims. (Cl. 248-278) This invention relates to adjustable supports providing universal movement and, in particular, to such supports wherein the movement is subject to tension.
In applicants prior Patent No. 2,278,356 dated March 31, 1942, entitled Mounting for Electrical Connectors, there were disclosed manners of mounting electrical connectors for universal movement and for imposing control upon that movement. Experience has shown that the construction of said patent was effective to the extent expected of it. Under certain conditions, however, a more effective construction is needed.
One of those conditions is where relatively heavy objects or lighting fixtures, are to be supported. Another is where small smooth movements of the support elements are to be made even though the tensioning means is exerting substantial resistance. Further conditions and improvements are to further protect an electrical conduit by eliminating sharp bends in it and keeping it from being acted upon or worn by the tensioning means. Also, a more effective application of the tensioning force is provided for along with an increase in and'a facilitating of the adjustability of the tensioning means.
It is, accordingly, a principal object of this invention to provide improved, universally operable, connector mountings.
Another object is to provide such mountings with improved tensioning means therefor.
Another object is to provide more effective adjustability of the tensioning means for such mountings.
A further object is to provide for increased variation in the tension control imposed on such mountings.
A still further object is to provide for even movement of the elements of such mountings regardless of the tension applied thereto.
Further and more detailed objects will in part be ob-' vious and in part be pointed out as the description of the invention, taken in conjunction with the accompanying drawing proceeds.
in that drawing:
Figure 1 is a side elevation of a mounting in accord ance with the invention carried by a wall bracket and showing in dotted lines the manner in which it supports a light socket.
Figure 2 is a front elevation thereof with the dotted line showing of the socket omitted. 1
Figure 3 is a top plan view of the mounting as shown Figure 8 is a sectional, partly exploded view, of the tensioning and pivoting element adjacent the head of the lamp in Figure 7, and
Figure 9 is a horizontal section taken on line 9-9 of Figure 8 and looking in the direction of the arrows.
The support or mounting device of my invention, as illustrated in Figures 1 through 6, is shown as carried by a wall by means of the carrying arm 1, having a tongue 2 received in the slotted holder 3. The arm 1 opens out into a yoke 4 whose arms embrace the barrel meinber 5 and are secured thereto by means of the screws 6. The interior surface 7 of the yoke fits the exterior of the member 5, so that when therscrews 6are in place, the barrel and the rest of the support extending from it will be firmly mounted in desired position.
The barrel member 5 as here shown is formed as a section of apiece of pipe whose lower end is screwthreaded, as shown at 8, to receive the screw threaded 'cap 9. The outer surface of that cap is knurled, or otherwise roughened, at 10 to enhance the gripping of it for turning. The bottom 11 of the cap 9, as shown in Figure 4, is centrally perforated, as shown'at 12, in order to enable an electric conduit to be passed up therethrough.
The upper portion of the barrel member 5 is screw threaded at 13 for reception within a screw threaded bushing 14, whose upper end is flanged outwardly at 15. Part of the circumference of the screw threaded portion 13 of the barrel 5 extending down from the top of that barrel is removed in order to provide opposed stop shoulders 16, a little more than 180 apart. Thus, when the barrel 5 is screwed intothe bushing 14 to desired extent and the screw 17 is inserted through the wall of the bushing 14 to project inwardly thereof, the relative rotative movement of the barrel 5 and bushing 14 about their common axes will be limited to the extent shown by the arrows A-A in Figure 3.
A head 18, in the form of a cylinder with a closed upper end 19, is seated on the flange 15 by means of its flange 20 which mates therewith. These fianges'are suitably secured together by some'means such as the screws 21, preferably inserted up from the underside of the flange 15. The flange 15 is recessed downwardly at 22 adjacent its inner edge to provide a seat for a plate 23. This plate is of proper thickness to be clamped in place on the seat 22 when thefianges 15 and 20 are secured together, inasmuch as a portion of the flange 20 will then overlie a peripheral portion of the plate 23.
' The plate 23 is provided with a center threaded opening therein for the reception of a screw threaded nipple 24. This nipple, as shown, is locked in place by means of a nut 25 engaging an extending portion of the nipple in Figure 1, with part of one of the elements partly broken away to expose the interior section thereof.
Figure 4 is a vertical section, taken on line 4-4 of Figure 3, of the left hand element of the Figure 3mounting with portions of that element broken away to show the interior thereof.
Figure 5 is a horizontal section taken on line 5-5 and drawn down tightly against the upper surface of the plate 23. Furthermore, the nipple 24, as seen in Figure 4, extends part way down into the'barrel 5 with that extending part being surrounded by-several of the upper coils of a tensioning spring 26. The spring 26 extends throughout the height of the barrel 5 having its upper end engaging the undersurface of the plate 23 and its lower end engaging the innersurface of the caphead 11 around the opening 12 therethrough.
From the foregoing, it will be apparent that, when this element is assembled, turning of the head 18 can be effected throughout an angle of due to the threaded engagement of the upper end of the barrel 5 with the interior of the bushing 14. It will also be apparent that turning action beyond 180 is precluded by the engagement of the inward extending portion 27 of the screw 17 with the stop shoulders 16 on the barrel 5. It will further be apparent that the desired tension to be imposed upon that turning action, once the proper spring is selected, can be effected by compressing 26, either by means of the position of the cap 9 on the bushing 14, or both, on the barrel 5. Obviously, a spring of suitable strength would be chosen and when that is done, the range of variation in the action thereof can be substantial. Further, since both ends of the spring seat against substantially flat surfaces, the resistance to turning even though substantial will be even and smooth throughout. Finally, it is to be noted that should the support be used for a housing for an electrical conduit, such can be passed up through the opening 12, through the spring 26, and through the nipple 24 without any injury to the same regardless of the turning action.
smooth action will be provided even though tension in suflicient extent to maintain a heavy element in desired position is applied. It is further to be noted that the bases 39 of the cylindrical pockets 37 isolate the springs 40 from any possible engagement with an electrical conduit passing through the element from the pipe 28 into the pipe 44. Thus, there is nothing to work on or chafe the conduit. Instead, it is protected from any such action.
In the assembly of this tensioning and connector element, it is first necessary to seat the sleeve 36 within the collar 41 and center it therewithin, so that the threaded This protection of an electrical conduit is further effected by the provision of a chamber of substantial size within the head 18. Thus, the conduit can follow a full smooth curve as it comes out of the nipple 24 and turns at a 90 angle to enter the pipe 28.
The pipe 28 is screw threadedly received in an opening in the cylindrical side wall of the head 18 and is clamped in place in that opening by a nut 29 engaged with the portion of the pipe extending within the chamber of the head. The portion of the pipe extending out beyond the head 18 has a screw threaded collar 30 applied thereover and turned up so that its inner end 31 engages the outer surface of the head 18. The collar 30 has a center knurled portion 32 to facilitate the turning of it and extends in symmetrical portions on either side of that center portion. Further, the collar 30 not only serves as a clamp and to provide an ornamental exterior but also serves as a joining element should the pipe 28 be made up of separate sections. This latter would normally be the case and the inner section would terminate at a position, such as 33, leaving the outer section of the pipe 28 somewhat spaced therefrom to facilitate the necessary adjustment for takeup when the parts are assembled. In any event, whether the pipe 28 is made up of one piece, or several, it will be apparent that it, along with the collar 30, not only serves as an element of the support, but, if desired, also serves as a protective housing for an electrical conduit.
The extending end of the pipe 28 is threadedly received in a center section 35 of a sleeve 36. This sleeve is of generally cylindrical form and has identical cylindrical pockets 37 extending into the ends thereof. Each of these pockets has a side wall 38 and a base 39 for the engagement of the inner end of a spring 40. The center section 35 of the sleeve extends throughout only a small portion of the circumference of the sleeve, as can be readily seen from the showings in Figures 3 and 6.
A collar 41 is seated over the sleeve 36 in rotatable relation with respect thereto, and, like the sleeve 36, is generally cylindrical in shape. The ends of the collar 41, besides having their inner surfaces in a slidable fit with the outer surface of the side walls 38, also have their exterior surfaces screw threaded as seen at 42. The intermediate joining section 43 between the ends 42 extends only part way round the circumference of the collar and receives an extending pipe, or other mounting member 44, within the body thereof. This pipe, or other member, is preferably permanently secured to and in an opening in the joining portion 43. V
Identical cap members 46' are screw threadedly engaged with the threads of the collar end portions 42. This threaded interengagement of the members extends for several threads unless the cap is practically unscrewed. The base 47 of the cap provides a smooth surface for engaging the outer end of the spring and the spring selected will, of course, be of proper strength so that when one is employed at each end of the element, adequate tensioning of the movement of the collar carrying the outlet 44 with respect to the sleeve mounted on the inlet 28 can be provided. It is also to be understood that the seating of the springs in their pockets and the tensioning of them in this manner with their ends engaging proper receiving flat surfaces, assures that an even,
perforation for the reception of the pipe 28 comes in the circumferentially removed section of the collar 41. When this is done, the pipe 28 is threaded into the opening provided for it in the engaging section 35, and the first step of the assembly is complete. Following this, the springs 40 are seated in the pockets 37 and the caps 46 are engaged with the ends 42 of the collar, and are turned down evenly until the right tension is reached. If an electrical conduit is passed through the pipe 28, and through the center of the sleeve and collar and out through the pipe 44, it will be obvious from the removed circumferential sections indicated, that a substantial swinging action of the collar on the sleeve can be effected without injury to such conduit. That swinging action, as indicated by the arrows BB in Figure 1, can readily be throughout an angle of before either of the opposite stop edges 48 of the center section 43 comes into engagement with the pipe 28.
The applicability of the construction of the invention to such as a table lamp is illustrated in Figures 7, 8, and 9. Here, a base, generally indicated at 50, is of the type normally used when the lamp would be mounted on a table. Obviously, however, the lamp could be extended to stand on a floor, or on any other surface desired. The construction here contemplated is that where the main upright member for the lamp is a pipe. As shown at 51 in Figure 8, this pipe would normally be enclosed within a tubular housing, generally indicated at 52, provided principally for the ornamental effect produced. This housing, whether made of one piece, or assembled of separate pieces such as 53, 54, and 55, is seated over the pipe 51 and is held in place and in assembled relation by being clamped between the upper surface of the base 5t), and the nut or washer 56 immediately beneath the screw cap 57. The bottom end of the pipe 51 would be threadedly received in a suitable nut, or fitting, within the base 50, as well known in the art.
The cap 57 like the cap 9 is screw threadedly received at 58 on the lower end of a barrel member 59. The cap 57 differs, however, from the cap 9 in the respect that its base 60 has the aperture 61 therethrough screw threaded for the threaded reception of the upper end 62 of the pipe 51. This threaded portion of the pipe also receives the nut 56, heretofore referred to, which nut engages the upper end of the tubular housing 52, whereby that housing is clamped between the upper surface of the base 50 and the under surface of the nut 56. The barrel 59 has its upper end screw threaded at 63 and such end, like that of the barrel 5 in Figure 4, has a portion of its periphery removed in order to provide stop shoulders 64. The end 63 is screw threadedly received within the bushing 65, whose flange 66 is mated with and receives the flange 67 of the cylindrical head 68, substantially the same as that shown at 18 in Figures 1-4. Here, however, the flange 66 includes a base across the end of the bushing 65, instead of using a plate as at 23 in Figure 4. The base portion of the flange 66 has a screw threaded opening at its center for the reception of the screw.
threaded nipple 69, which latter preferably extends through the flange 66 and is locked in place by means of the flat nut 70.
A spring 71, like the spring 26, is received within the barrel 59 and compressed between the under surface of the flange 66 and the inner surface of the base of the cap 57. Like the form of Figures 1-4, theselection of a spring 71 of suitable strength, and the adjustment of the compression of the same controls the resistance applied against the turning of the head 68 with respect to the pipe 51 and the base 50. This structure differs from that of Figures 1-4, however, in the respect that the cap 57 cannot be turned as readily to vary the compression of the spring 71' as can the cap 9 in varying the compression of the spring 26. In fact, the preferred condition would be to set the cap 57 up tight on the barrel 59 to make sure that any turning actionwere limited to that of the head 68, with respect to the barrel 59, otherwise, the lamp might become loose-jointed and, accordingly, undesirable. Thus adjustment of the compression of the spring would be made solely by backing 'up the stop screw 72 and turning the head 68'with respect tothe barrel 59. When the bushing has been screwed up or down far enough, the screw 72 is reinserted and the range of turning movement of the head 68 is again limited to 180.
Like the form of Figures 1-4, the form of Figures 7-9 is provided with a large chambered head 68, so that an electrical conduit passed up through the pipe 51, through the nipple 69 and turned at right angles to pass out through the pipe 73 will have freedom of movement within the head 68. Thus, the wear or chafing of an electrical conduit within the head 68 will be kept at a minimum in spite of the turning, or adjusting of the head 68 with respect to the barrel-59.
The pipe 73 is received within the side wallof the head 68, in the screw threaded opening 74. Besides being threaded into this opening, the pipe is locked in place therein by a threaded nut element 75 and the pipe 73 likewise receives screw threaded collar elements, such as 76, like the collar elements 30 of Figure 4. In other words, again the threaded collar element 76 may be in one piece, or several pieces and the extentof the whole assembly or of the one-piece construction, may be determined by such factors as the length to be taken care of and the purpose to be served, such as the joining of separate pipe elements as against overlying a continuous pipe element.
The collar element 76 is here shown as terminated in another knurled nut element 77 prior to engagement of the pipe therewithin with the other adjustable element of the support here shown at 78. This element 78 is in every respect the same as that shown at the right hand side of Figure 3, and in the exploded view of Figure 6. Thus, reference is made to the showing of those figures for the details of element 78. a
The pipe such as 4 which extends from the element 78 in this instance carries a conventional light socket 79 to which is applied a reflector 80; It is believed to be apparent that the light emanating from the source within the reflector 80 can be directed throughout with respect to the horizontal axis of the element '78 and throughout another 180 with respect to the vertical axis of the head 68. All such movement, as previously fully described, is subjected to resistance by spring action of such a nature as to insure that a position once set will be maintained, though enabling the setting of the position throughout a substantial range to be effected with ease and uniformity. Also, adequate provision is made for effective adjustment of that resisting action whenever that may be desired.
Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
