SUSPENSION-HOOK FOR CHANDELIERS.

SPECIFICATION forming part of Letters Patent No. 250,611, dated July 3, 1883. Application filed April 14, 1883. (No model.)

- To all whom it may concern Be it known that 1, WILLIAM E. HAMMOND,

of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Suspension-Hooks for Chandeliers; and I do hereby declare that the followingis a full, clear, and exact descrip tion thereof, reference being had to the accompanying drawings, making part of this appli cation. My invention relates to certain new and useful-improvements in suspension-hooks, such as are adapted to be and are used in ceilings to effeet the suspension of lamp-fixtures, &c. Heretofore such contrivances have been constructed in a variety of ways adapted to permit the easy insertion within the suspension-hook of an eye or ring of any article to be suspended therefrom, and at the same time not permit the easy removal of said eye or ring from the said hook, the object of having suspensionhooks adapted to operate in this way being, as is well understood, to prevent the casual disengagement from the hook of any fixture suspended therefrom which may have to be cleaned and handled, and in the course of do ing which it may be lifted. Most of these automatic suspension-hooks, or, more properly speaking, safety-hooks, as constructed heretofore, have been more or less complicated.

The purpose of my invention is to provide for use a safety suspension-hook which, while it shall be capable of having readily suspended Y or hung thereon any device which itmay' be desired to hang up, and of preventing any accidental disengagement-of the suspended fixture from the hook, shall be exceedingly simple in its construction, economical of manufacture, and neat in its appearance; and to thesemain ends my invention consists in a suspension-hook provided with a simple pendant which is so shaped and arranged that its lowermost edge or end shall hang relatively to the opening of the suspension-hook in a manner such that the ingress or introduction through the usual opening of the hook of any ring-like or other device to be suspended in the hook will simply swing to one side the said pendent device, so that the entering ring-like device of the article to be suspended will pass by the pendant and settle itself in the lowermost portion of the hook, as usual, while at the same time any upward movement of the device of the suspended article, after the pendant shall have resumed its normal position, will operate to force the pendant either dead againstits axis of vibration or against its axis and at the same time slightly toward the opening of the hook, so that it will be impossible for the suspended device to become disengaged from the hook by any such upward movement of the ring-like suspended devices.

To enable those skilled in the art to which my invention relates to make and use the same,

I will now proceed to more fully describe the construction and operation of my improved suspension-hook, referring by letters of reference to the accompanying drawings, making part of this specification, and in which Figure 1 is an elevation or side view of a suspension-hook made according to my invention. Fig. 2 is asimilar View, showing amodified form of hook, made, however, upon the same principle of construction and embodying substantially the same mode of operation. Fig. 7 5 3 is a View similar to Fig. l of the same form of hook therein shown, but illustrating the operation of the pendent device, the latter being represented as swung to one side or forced to one side by the insertion of the ring-like 8o device or eye of some article adapted to be suspended within the hook.

In the several figures the same part will be found designated by the same letter of reference. 8 5

A is the hook, made preferably of the pattern shown, but which may be of any desired design, and which is adapted to be secured and fastened to the ceiling or other place from which the article and lampfixture are intended to be 0 suspended.

Within the hook-like devices A there is pivoted (in this instance about centrally) a pendent and cam-like device, 12, the size and shape of which are such, as shown, that when in its nor 9 5 mal position said swinging device 1) comes almost in contact, at one'of its lowermost corners, with the inner edge or portion of the end 0 of the hook. The function and effect of the suspended device I) will be best understood by 2 280.,6lll

reference to Fig. 3 of the drawings, in which I have shown said device swung to one side, where it is held by the introduction into the throat of the hook Act the ring-like device 0 of the lamp or other fixture designed to be suspended by the hook, and it will be understood that when said device 0 shall have been fully entered and shall have assumed its natural and proper position in the hook A, as rep resented by the dotted lines in Fig. 3, said pendent device I) will by gravity swing back into its normal position seen at Fig. 1., and that then any casual lifting of the fixture suspended by the ring 0 will operate to push up ward on the device I), and simply crowd it against its axis, while any such upward movement of the device (I, combined with any lateral motion in the direction of the opening of A, will operate to not only force the device I) against its dead-center or axis of motion, but will also tend to rock itself, at its lower portion, toward the throat A, which tendency will only operate to wedge the device I) more sccurely between the upper portion of the device c and its own axis, thus insuring a deadlock of the parts in contact and effectually preventing any escape of the device 0 from the hook A.

In the form of hook shown at Fig. 2, and the relative arrangement there shown of the pendent device (I, the latter is pivoted at or near the root of the hook C, but operates, it will be seen, in substantially the same manner as the pendent device I), (shown in conjunction with that form of hook seen at A in Figs. 1 and 3.)

It will be understood that in a contrivance made as shown and described, the structure is exceedingly simple and not liable to derange ment, is positive in its operations, and can be very cheaply manufactured of various designs or pat-terns, according to the taste and wishes of the manufacturer.

Having so fully explained the nature of my invention that those skilled in the art can make and use my improved safety suspensionhook, what I claim as new, and desire to sccure by Letters Patent, is

A safety suspension-hook composed of a suitable hooklike device or casting, A, adapt ed to be secured. to the ceiling or other place in which it may be desired to use such hooks, and provided with a frcely-swinging pendant or device, substantially such as shown and described, and which is adapted to swing to one side when the device to be suspended shall be passed into the hook and downward toward the bottom thereof, and which operates with a tendency to swing toward the hook-opening by contact with its lower curved surface of the device suspended in the hook whenever the said device may be lifted or moved in a dime tion such as might, in the absence of said pendant, permit its escape fromv the hook, all substantially as specified.

In testimony whereof I have hereunto set my hand and seal this 10th day of April, 1883.
