UNITED STATES PATENT OFFICE.

ANTONY P. BUXTON, OF MERIDEN, CONNECTICUT, ASSIGNOR TO THE BRAD- LEY & HUBBARD MANUFACTURING COMPANY, OF SAME PLACE.

HANGING LAMP.

SPECIFICATION forming part of Letters Patent No. 336,035, dated February 9, 1886.

Application filed April 20, 1885.

To all whom it may concern:

Be it known that I, ANTONY P. B'UXTON, of Meriden, in the county of New Haven and State of Connecticut, have invented new Improvements in Hanging Lamps; and Ido here by declare the following, when taken in con nection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a side view of the hanger, showing the rosette in section; Fig. 2, a top view showing the body in partial section with the loop in its down or folded position; Fig. 3, a transverse section through the body, showing a side view of the loop in its up position; Fig. 4, a transverse section through the bend or bearing point of the loop.

Thisinvention relates to an improvements in the hanger by which lamps are suspended, particularly applicable to that class in which pulleys are arranged in the hanger, over which chains or cords extend from the lamp to a weight, so that the lamp itself may be made adjustable to different elevations. In many of this class of lamps a central rigid rod is employed, to the upper end of which the hanger is secured, the lamp below being attached to a tubular rod arranged telescopically over the rod, which extends down from the hanger, and so that in adjusting the lamp to different elevations the tubular rod works up and down on the rod from the hanger as a guide. The hanger is provided with a loop, by which it may be hung upon a hook in the ceiling. This loop projects upward from the hanger, and increases the length of the fixture to that extent. Compactness of packages in transportation is very desirable on account of freightcharges. As usually constructed the hanger is substantially hidden by a rosette, as indicated in Fig. 1. The extension of the hanging loop upward adds materially to the size of the package over what it would he were the loop not present. Again, the loop as it hangs up on the hook takes but a very short bearing thereon, substantially a point, and hence permits the fixture to swing under a very slight 5o impulse.

The objects of my invention are to construct Serial No. 162,745. (No model.)

the hanger so that it may be brought into a more compact form than with the usual rigid loop, and also to make the engagement between the loop and suspending-hook of such a nature that the easy swinging of the fixture is avoided; and the invention consists in the construction as hereinafter described, and more particularly recited in the claims.

A represents the body of the hanger, and is 6c shown as arranged for two cords or chains. It therefore carries two pulleys, B. At the center of the body is an upward projection, C. The loop is of U or V shape, the two legs D D of which are each constructed with a trunnion, a, arranged in corresponding seats in the upwardly-extending portion C of the body, and upon which trunnion the loop may be turned from its up position seen in Fig. 3 to a down or horizontal position, as indicated in yo broken lines, same figure, and also seen in the down position, Fig. 2. At the same end one or both of the legs are constructed with a transverse projection, b. The inner surface of these extensions 1) are rounded, as seen in Fig. l. The adjacent surface of the projection C is constructed with correspondingly-shaped recesses d, and so that when the loop is applied in its up position the projections 12 will enter the recesses d, and there be held under the natural. elasticity of the two arms D D of the loop, it being understood that the tendency of this elasticity is to cause the legs to approach each other.

As the loop is turned from the vertical po sition seen in Fig. 1 or Fig. 3 the projections b act as cams in the recesses 01 on the hanger and force the legs up, so as to permit them topass out of the recesses. Then the movement of the loop may be continued until it reaches 0 its horizontal position. (Seen in Fig. 2, and in brokenlines, Fig. \Vhen again the loop is raised, the projections b will swing into the recesses d and hold the loop in the up position-that is, in the proper position for applying to the suspending-hook.

The projections b, with their corresponding recesses, are desirable to support the loop in its vertical position; but they may be omitted and the loop depend upon frictional contact of its trunnions for such support.

In order to give the loopa firm support upon the hook, I construct it with a transverse projection, e, on each side at its apex, as seen in Fig. 4. These projections are curved upon the under side and grooved, so as to form a segment-shaped groove or seat to rest upon the hook. The curve and groove should corrcspond to the shape of the hook, as indicated in broken lines, Fig. 4. This givesa longbearing for the loop upon the hook. It cannot swing to the right and left from the position seen in Fig. 4 without the loop rubbing or sliding upon the surface of the hook, which it 'cannot well do, owing to the great friction there will be upon it. In the transverse direction it cannot swing,because ofthe curved bearing which the loop has upon the hook; hence the loop while being suspended by the common chandelier-hook makes a firni and strong connection with that hook, so as to substantially avoid the tendency of the chandelier or lamp to swing under a slight impulse. This'construction of loop to give theincreased or supporting bearing upon the hook may be applied to lamp or chandelier hangers generally. I therefore do not wish to be understood as limiting this part of my invention to a hanger in which theloop is adapted to be turned from its vertical into a horizontal plane.

By constructing the loop to be turned as I have described it materially contracts the extent of the hanger, and correspondingly reduces the size of the package which contains it, and if made from cast-iron, as such parts usually are, the turned-down position of the loop leaves it less liable to breakage or injury in packing and transportation than when in fixed vertical position.

I claim 1. In a lamp-hanger, the body constructed with bearings to receive corresponding trunnions on the loop with one or more transverse recesses, (I, combined with a loop, D, constructed with trunnions adapted to work in said bearings, and with a transverse projection, b, corresponding to and adapted to engage said recess in the body, substantially as and for the purpose described.

2. In a lamp-hanger, the loop on the hanger and by which the hanger is suspended, the saidloop constructed with a transverse projection, e, on each side at its apex and at right angles to the plane of the loop, the said projections curved upward upon their under side, and the under curved surface constructed with a concave groove at right angles to the plane of the loop and so as to form a concave segment-shaped groove at the apex of the loop, substantially as described.
