ADJUSTABLE SUPPORT.
SPECIFICATION forming part of Letters Patent No. 779,453, dated January 10, 1905.
Application fil June 24, 1904. Serial No. 213,974.
To all whom, it may concern.
Be it known that I, OTIS C. WHITE, a citizen of the United States, residing at WVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Adjustable Support, of which the following is a specification.
This invention relates to an adjustable support which has been especially designed for incandescent electriclamps, but which can also be used for other purposes.
The especial objects of this invention are to provide a supporting-strap for fastening the support to a desk or similar fixture without scratching or marring the woodwork and to provide a flexible frictional joint for carrying a rod or pipe section, so that the same can be turned or adjusted to any desired position and will remain in the position to which it is set.
To these ends this invention consists of the fastening-strap and of the adjustable joint-as articles of manufacture and of the combinations of parts therein, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.
In the accompanying two sheets of drawings, Figure 1 is a side view illustrating the use of an adjustable support constructed according to this invention forcarrying an incandescent electric lamp. Fig. 2 is a detail view of the fastening for the adjustable strap. Fig. 3 is a detail view of the adjustable footpiece, adapting the fastening-strap to desktops or boards of different thickness. Fig. 3 is a view showing in perspective the several parts which cooperate to form a joint according to this invention. Fig. 5 is a sectional view of the complete joint, and Figs. 6 and 7 are detail perspective views illustrating a modified construction to be hereinafter referred to.
The fastening-strap which I preferably employ for an adjustable support constructed according to this invention comprises two sheet-metal strap-pieces, one of the strappieces being provided with ratchetteeth,while ,the otherstrap-piece carries an operatinghandle and locking-pawl cooperating therewith. The strap-pieces are provided at their ends with hooks for engaging the sides of a desk-top or other board.
The flexible joint of an adjustable support constructed according to this invention is mounted upon a pin which is preferably arranged vertically. In the preferred construction of this flexible joint I employ two bearing-cones which fit onto the pin. The bearing-cones are held in place by clamp-pieces. Each of the clamp-pieces is provided with two clamping-jaws. One set of clamping-jaws engage the bearing-cones, and the other set of clamping-jaws engage the rod or pipe section. The clamp-pieces are fastened together by a screw, and in the completed joint the rod or pipe section can be turned or swiveled in one set of clamping-jaws, the clamp-pieces will pivot or turn on the bearing-cones, and the bearing-cones can be rotated upon the pin. The frictions of all these several adjustments are controlled from a single clamping-screw, and in order to adjust the joint for supporting heavy weights it is simply necessary to tighten the nut on the clamping-screw, while when light weights are to be supported the nut can be left comparatively loose, permitting easier adjustments.
Referring to the accompanying drawings and in detail, the fastening-strap comprises sheet- metal pieces 10 and 11. The sheetmetal piece 10 is provided at its end with a hook and has ratchet-teeth on its upper side, as shown in Fig. 2. The ratchet-teeth of the sheet-metal piece 11 may be formed in any usual way. In the construction illustrated the ratchet-teeth are formed by slots or recesses cut into the surface of the sheet-metal piece 10. Fastened near the end of the other sheetmetal piece, 11, is a stirrup 12,pivotal1y supported in which is an operating-handle 14, carrying a pawl 15 for engaging the ratchetteeth. The sheet-metal piece 11 is preferably provided at its opposite end with an adjustable hook-piece. v
As shown in Fig. 3, the end of the sheetmetal piece 11 is bent down and is provided with a vertical corrugation having a perforation concentric therewith. Fitting inside of the turned-down end of the piece 11 and held in place by lips 18 is an adjustable hook 17, having a tongue 19, which runs up and down in the corrugations 16 and which is tapped out to receive the adjusting-screw 20, which extends down through the perforation in the piece 11. By turning the screw 20 the adjustable hook 17 can be raised or lowered for use on boards, desk-tops, or other fixtures of different thickness.
Fastened in the sheet-metal piece 11, preferably by being headed through a number of reinforcing-plates, is a pin 21, upon which the adjustable joint is carried. The parts of the adjustable joint are most clearly illustrated in Fig. &. As shown in this figure, the pin 21 is provided with an enlargement 22, at each side of which are reduced bearings. Fitting on the pin are bearing-cones 23, which are provided with cored-out sockets for receiving the enlargement 22 of the pin, so that the bearing-cones will be held from vertical displacement when clamped onto the pin. Cooperating with the bearing-cones are clamppieces 24 and 25. Each of the clamp-pieces is provided with two sets of clamp-jaws. One set ofclamp-jaws, 26,engage the bearing-cones 23, while the other set of clamp-jaws, 27, receive the rod or pipe section 28, as shown in Fig. 1. To fasten the joint and regulate the friction of the several adjustments thereof,
I provide a single clamping-screw 29, having a square section for engaging a correspondingshaped socket in the clamping-piece 24:. At the other end the fastening-screw 29 is provided with a washer 30, which is preferably slightly arched or bent to form a springwasher, and threaded onto the screw 29 is a hand-wheel 31. In the completed joint the parts are assembled as shown in Fig. 5, and in the completed joint the rod or pipe section can be turned in the clamping-jaws 27, the clamp-pieces can be turned upon the bearingcones 23, and the bearing-cones can be turned upon the pivot-pin, the friction of all these several adjustments being regulated by the single clamp-screw and its hand-wheel.
The rod or pipe section 28, as illustrated in Fig. 1, may be connected by an elbow to support a lamp-socket L or may be used for supporting any other article which it is desired to support in a variety of adjusted positions.
In some cases in addition to the swiveling of the rod or pipe section 28 in the clampjaws 27 a slipping or telescopic adjustment of the rod or pipe section through the jaws 27 may be desired, and when this is the case I preferably employ the construction illustrated in Figs. 6 and 7 that is to say, I inclose within the clamp-jaws 27 a four-arm spring 32, as shown in Fig. 6, the ends of two of the arms engaging sockets 33 to hold the spring from displacement, while the body portion or center of the spring may be engaged by a setscrew 34:. (Shown in Fig. 7.) By adjusting the set-screw 34 I secure an adjustable springpressure upon the rod or pipe section 28, permitting the same to slide longitudinally through the clamping-jaws in addition to turning or swiveling therein.
In the special construction which I have herein illustrated I have shown the bearingcones 23 having surfaces or frustums of ordinary right-line cones, although the bearingsurfaces of the cones may, if desired, be somewhat curved or conoidial in form or may even approximate sections of spherical surfaces, and while I have herein illustrated the pivotpin of my improved joint carried by a special fastening-strap it is to be understood that this pivot-pin may be attached to or extend out from any other base, fixture, or support, so far as the application of the adjustable joint thereto is concerned.
I am aware that numerous changes may be made in practicing my invention by those who are skilled in the art and that certain features of my invention may be used in different combinations and in different relations without departing from the scope of my invention as expressed in the claims. I do not wish, therefore, to be limited to the constructions I have herein shown and described; but
hat I do claim, and desire to secure by Letters Patent of the United States, is-
