SPECIFICATION forming part of Letters Patent No. 771,219, dated October 4, 1904.
Application filed September 10, 1902. Serial No. 122,863. (No model.)
To aZZ whom, it may concern:
Be it known that I, ARTHUR J. ADAMS, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Extension-Gas-Bracket Supports, of which the following is a specification.
My invention relates to improvements in means for supporting an adjustable or extension gas bracket or fixture, whereby the latter may be easily and quickly adjusted at different heights, and when adjusted will be securely held in place.
One of the objects of my improvements is to provide a device of this character that will take the weight of the bracket from its joints or couplings, thereby preventing great wear on the latter and consequent leakage.
A further object is to so construct the device that the locking of the bracket in its adjusted positions will be instantaneous and positive, thus preventing any slippage. I have also had in mind the importance of a construction that would be sightly as well as secure and durable.
With these and other objects of general utility and economy of manufacture in view I have designed the device shown in the accompanying drawings, in which Figure 1 shows in elevation an extensible gas-bracket equipped with my adjusting and holding mechanism. Fig. 2 is an elevation of the adjusting and holding means, taken at right angles with the view of Fig. 1. Fig. 3 is a detail of the clamping device which forms a part of my invention. Fig. 4 shows the part illustrated in Fig. 2 with the gas-bracket extended the full limit. Fig. 5 is a detail of amoolified form of clamp; and Fig. 6 is a view, partly in plan and partly in section, of the parts shown in Fig. 5.
Referring to the drawings in detail, A represents a branch pipe of a stationary gas-fixture, near the outer end of which is the usual stop-cock a, and to the extreme end of which is secured a valve-socket E, adapted to receive a conical valve of ordinary construction. The
socket is formed with an extension 6, which is internally bored and threaded and has its upper end flattened to aflord a broad bearingsurface for the holding-bracket D, which is secured to the socket by a bolt 6 which passes through a suitable hole in the bracket and into the threaded bore of the extension 6.
The bracket D is preferably formed from sheet metal of sufficient thickness to afford a firm support for the parts which are attached thereto. It has a flat horizontal portion d, which rests upon and is secured directly to the socket e, as described, and is formed with a downwardly-depending portion (Z the lower end of which is bent up at right angles to form an extension d, which is parallel with the top portion of the bracket and extends in the same direction from the part (Z In the portion (Z is cut a small hole (Z to receive the shank of the tripper (Z and through the top of the bracket and the extension cl are cut round holes d, which register with each other and receive the bracket-holding rod B. Secured to the inner end of the tripper is a collard, the diameter of which is materially larger than that of the rod B,which it surrounds at a point midway between the top of the bracket and the extension 6Z so that there may be interposed between the collar and said rod two clamping-plates (Z which are fitted to the rod B, as shown in Fig. 4, and are adapted to clamp and to release said rod as the tripper is operated.
The supporting-rod B is provided at its upper end with a knob or button 5 and is-secured at its lower end to the branch 0" of the valve-socket O. This rod, in connection with the bracket D, supports the weight of the jointed bracket F and the burner, chimney, and shade attached thereto and accommodates itself to the various adjustments of the gasbracket by sliding vertically in the openings d in the bracket D, when the clamping-plates d are released. The plates (Z are slightly wedge-shaped, the cross-diameter of their upper part being greater than the bore of the ring d thus preventing the plates from slipping through the ring (Z when the rod is moved downwardly When the rod is pushed up, the weight of the plates overcomes the frictional contact with the rod, thus preventing the plates from being pushed out of the collar.
The bracket F is connected with the pipe A by pipes 0 c and sockets U, 0 c, and E, all of which are of well-known construction and adapted to effect gas-tight joints and permit the movement of the pipes in adjusting the bracket.
To facilitate pulling down the tripper, I secure to its outer end a chain Gr, which terminates in a ring which will hang within easy reach. The construction of the clamp is such that so long as the outer end of the tripper is down the rod will slide freely in the clampingplates; but as soon as the tripper is released the friction between the plates and the rod will cause the latter to bind in a manner that will be readily understood, and thus lock the rod against further movement until the tripper is again pulled down. This same function or manner of operating applies to the form of tripper illustrated in Figs. 5 and 6, though the construction of the latter is somewhat different from that shown in Fig. 4. In the modified form the inner end of the tripper is secured to a plate d", from which extends a small lug which fits loosely in a hole in the center of a semicylindrical plate (Z placed in frictional contact with the rod B. Vhen the plate d is at right angles to the plate (F, it presses the latter against the rod; but when tilted from its horizontal position the frictional contact will be lessened, all in a manner well understood.
Various other forms of tripping and clamping means may be devised which embody the essential features shown and described in my invention, and I therefore do not wish to be limited to the particular constructions herein illustrated; but
What I claim, and desire to obtain by Letters Patent, is-
1. In a device of the character stated, jointed v gas-pipes connected with the gas-fixture, and means for adjustably supporting said pipes consisting of a rod pivoted on one of the pipes, a bracket removably secured to the fixture and having alined opening in which said rod is slidably arranged and means for holding said rod in its adjusted position, said means consisting of plates frictionally embracing the rod, and a tripper adapted to move said plates to release said rod.
2. In an adjustable support for extensible gas-brackets, a plate secured to the gas-fixture and extending at right angles therefrom, and provided with perforated flanges, a rod secured at one end to the outer branch of the extensible bracket and slidably fitting the perforations in the plate, a tripper pivotally supported in said plate and having a collar embracing said rod, and frictionplates interposed between said collar and the rod, substantially in the manner and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
