AUTOMATIC HANGER.

Specification of Letters Patent.

Serial No. 637,572.

To all whom it may concern:

Be it known that I, AMZIE A. TEETS, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Automatic Hangers, of which the following is a specification.

My invention relates to an improved form of hanger or carrier which can be automatically locked in position or automatically released at the will of the operator.

In the accompanying drawings which I will presently describe I have shown my invention applied as a hanger for an electric arc lamp but it is obvious, as will clearly appear as this description proceeds that my invention may be utilized for and is applicable to many other useful purposes.

In said drawings in which the same reference sign denotes similar parts: Figure 1, is a central longitudinal section of the device embodying my invention. Fig. 2, is a crosssection thereof taken on the line 2, 2, and looking in the direction of the arrows. Fig. 3, is a top plan view of the lower member of the device. Fig. 4, is an enlarged central longitudinal section of the device and showing the two halves detached and in their released position. Fig. 5, is a detail view in section.

Referring to the drawings my improved device is composed of two separable members, an upper member 1, and a lower member 2, which are adapted to be locked together or separated from one another as will hereinafter appear. The upper member 1, is of substantially cylindrical shape having a centrally arranged downwardly depending offset or Hange 3, and the lower member 2, is provided with a recess 4, adapted to receive the depending flange 3, when the two members of my device are in their locked position, as particularly shown in Fig. 1. The upper member 1, is provided with a central opening 5, which extends vertically through the flange 3, and above this opening 5, and in line therewith a recess 6 is provided preferably of greater diameter than the opening 5. A tube 7 is mounted in the opening 5, and firmly screwed in place therein as indicated at 8, Fig. 4; exteriorly arranged on this tube and on opposite sides thereof a flat spring 9, is xedly secured as by a screw 10, which passes through Vthe lower end of said spring and engages the tube 7. The free end of each spring 9, is respectively provided with an inwardly projecting tongue 11, and these tongues are adapted to enter the tube 5, through lateral slots 12, therein.

13 designates a tubular stem which extends upwardly through a central opening 14, in the member 2; a yoke 15, having a ring-shaped top 16, is movably mounted on the exterior of the stem 13, as by screws 17, which respectively engage an elongated lateral slot 18, extending through the stem and into the upper end of a tube 26, by means of which the tube 26, and the stem 13 are united together; the upper end of the stem is provided with a tubular cap 19, which is preferably in the shape of the frustum of a cone and is removably secured to the stem 13; the lower part of this cone is of greater diameter than the stem 13, thus forming a shoulder 21; before the cap 19, is applied to the stem 13, a loose ring 22 is slipped over the outer end of the stem and normally rests on the ring shaped top 16, of the yoke 15. After the cap 19 has been applied and secured in place, the ring 22 moves upwardly and downwardly in the space 23 between the shoulder 21, and the ring-shaped top 16 of the yoke 15, as my device is operated as I will presently describe. As shown the stem 13, is preferably secured to the member 2, by means of the nut 24, although it will be understood that any appropriate attaching means may be employed. The cap 19 is provided with a reduced shank 20, exteriorly screw-threaded and adapted to engage interior screw threads of the stem 13, as indicated particularly in Fig. 4; by this means and the screw 25, the cap 19, is firmly secured in place.

lA tube 26 preferably terminating at its outer end in a T 27 is inserted in the stem 13, from the lower end thereof, and this tube 26 is secured to the stem 13, by means of the screws 17 which passv through the elongated slots 18, in the stem 13. A spring 30, is coiled around the stem 13, and confined thereon in the space between the shoulder 3l, formed by the inner end of the shank 20, and the shoulder 32, formed by the upper end of the tube 26. A cable 33, has one end fastened to an eye ring 34, on the lower end of the tube 26, the free end of this. cable passing through the T 27, thence upwardly through tube 26, stem 13, tube 7, and thence to the usual over-head pulley.

My device is shown in the drawings as being utilized as a hanger for an electric arc lamp 35, which is secured to the T 27, as by a bolt 36. Then used for this purpose the under faces of the member 1, will be provided with a series of contacts 37, and the upper faces of the member 2, with a series of contacts 38, which as shown in Fig. 3, 1 prefer to make in the form of spring contacts so as to compensate for any slight separation of the two members 1 and 2, after they have been engaged in the locked position shown in Fig. 1, and thus insure a closed circuit through my device and thence to the arc lamp carried by it. 1n this connection it is to be understood that my device will be just as efficient as a hanger for incandescent clusters as it will be for arc lamps.

The operation of my device is as follows Vhen the parts are engaged as shown in Fig. 1, the tongues 11, of the springs 9, enter the slots 12, in the tube 7, and bear firmly against the underside of the shoulder 21, of the cone-shaped cap 19 of the stem 13, thus locking the members 1 and 2 together. 1f the cable 33, is now pulled upwardly the tube 26, will move upwardly in the stem 13, carrying the yoke 15, and its ring-shaped top 16, upwardly, the latter forcing the loose ring 22, up and into engagement with the tongues 11 of the spring 9, and forcing them outwardly and out of engagement with the shoulder 21, of the cap 19, thus releasing the parts. (See particularly Fig. 5.) 1t is to be noted that the inner ends of the tongues 11, are of tapering form so as to facilitate the quick outward movement of the springs 9, and their tongues 11, by means of the ring 22. As the tube 26, moves upwardly under the impulse of the pull on the cable 33, it compresses and tensions the spring 30, and the instant the pull on the cable 33, is released t-he spring 30, expands forcing the stem 13, and tube 26, downwardly and separating the members 1 and 2. The member 2 and the arc lamp or other object carried by it can thus be lowered in the usual manner. To unite the members 1 and 2, and engage them in the locked position shown in Fig. 1, it is only necessary to pull downwardly on the cable 33, whereupon the stem 13, will enter the tube 7, passing upwardly therein until its cone-shaped head seats inself as shown in Fig. 1, and the tongues 11, of the spring 9, automatically engage the shoulder 21.

A hanger embodying the characteristic features of my invention may be used as the supporting carrier for any object which it is desired to raise and lower and support at any predetermined point.

My device can be economically manufacf tured, and in practice will be found certain, reliable and efiicient for the purposes described.
