Specification of Letters Patent.

Application led April 2, 1909.

Patented Dec. 28, 1909. Serial No. 487,377.

To all whom it may concern:

.Be it known thatjI, HERBERT J. HINDS, a citizen of the United States, and a resident of I-Iillyard, in the county of Spokane and State of lVashington, have invented a new and Improved Adjustable Hanger for Lights, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide novel details of construction for an adjustable hanger, that is particularly well adapted for the suspension of a lamp or the like from an overhead support, and enable the vertical adjustment of th-e light at a desired height.

The invention consists in the novel construction and combination of parts, as is hereinafter described and denned in the appended claims. j j

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the improvement applied to the adjustable suspension of a lamp from the ceiling of a room; Fig. 2 is an enlarged longitudinal sectional view of the improved lam hanger, taken through the center thereo Fig. 3 is a transverse sectional view of the hanger reel, taken substantially on the line 4 4 inl Fig 2, parts being shown somewhat changed in adjustment from that shown in said ligure; Fig. 4 is a transverse sectional view of novel details, substantially on the line 1 /l in Fig. 2, seen-in the direction of 'the arrows m2, r2 in said view; Fig. 5 is a transverse sectional view of details, taken substantially on the line 5--5 in Fig. 2, seen in the direction of the arrows m3, w3 in said view; and Fig. 6 is a transverse sectional view, substantially on the line 6-6 in Fig. 2, seen in the direction of the arrows m5, 005 in said ligure.

The improvement is well adapted for the suspension and vertical adjustment of a pendent electric lamp, wherein a iiexible connection is employed that is an insulated electrical conductor, which is the preferred service for the improved hanger device.

In the drawings that represent one example of my invention, 10 indicates a suitable flexible connection that is pendent from an overhead support such as a ceiling A, a lamp 11 of any preferred construction hanging from the lower end of said flexible connection or cord 10.

The improved hanger device embodies a cylindrical reel 12, whereon the cord 10 is secured intermediately of its ends, and it will be seen that a rotary movement of the reel will wrap the connection 10 upon said reel and shorten it, thereby elevating the lamp 11, a downward pull on the cord l() serving to lower the lamp, as is more fully explained in the following specific description.

The body of the reel 12 consists of a cylindrical block of a suitable diameter and length, having at each end a cylindrical wall 12a formed or secured thereon, which walls provide lateral extensions of the peripheral surface of the reel, and affords twochambers a, b, one at each side of the body 12. Centrally in the reel body 12, a longitudinal perforation c is formed, wherein a shaft `13 is loosely inserted and projects through the lateral chambers a, Z).

On the ends of the cylindrical extensions 12a, two similar flanges l2b are concentrically secured, said circularly-edged flanges being dished on their inner sides, thus disposing their edges parallel and near to each other, as is shown in Fig. 2. A recess d is formed in the body 12 of the reel, said recess having parallel side walls anda proper depth, the bottom wall d thereof having an undulating form, as is clearly shown in Fig. 5. In the recess d, a clamping block 12C is loosely litted, the peripheral surface of which is curved, having the same radius as that of the main peripheral surface of the body 12, said clamping block being removably secured in the recess d by a clamping bolt e.

In thechamber a, shownat the left in Fig. 2, and also appearing in Fig. 6, a helical plate spring lil is introduced and secured at one end f upon the shaft 13, the outer end of said coiled spring being attached upon the inner surface of the deining wall 12a of said chamber a, as shown at g in Figs. 2and 6. In the opposite chamber o, a plurality of preferably equally-spaced segmental abutment blocks l1, are secured or formed, these blocks projecting from the inner surface of the circular defining wall 12a of the chamber and upon each block Iz, an inwardly-projecting lug /z is formed or secured, as shown in Figs. 2, 3, and 4 of the drawings. If the abutment blocks Ii are separate formations, each may be secured upon the peripheral wall of the chamber Z9 by a screw z', as shown clearly in Fig. 3.

In the chamber b, upon the central shaft 13, one end of an arm 15 is secured as shown at in Figs. 2, 3, 4, said arm at its remaining end being pivoted upon one end of a pawl Z, as shown at m. The length of the pawl Z is so proportioned, that its free end will be disposed near to the inner surface of the peripheral wall of the chamber Z) when the arm 15 and pawl Z thereon are disposed between the adjacent ends of two of the abutment blocks it, as is shown in Fig. 4. There is a short stud n projected laterally from the pawl Z where it is hinged upon the arm 15, and between said stud and the point of attachment of the arm on the shaft 13, a spring o is extended, and has its ends respectively attached thereto.

It will be noted that the pull of the spring will hold the arin and pawl in alinement when relatively positioned as shown in Fig. 4, but if the reel block is turned in the direction of the arrow w in Fig. 4, the pawl will be impinged upon the end of the abutment block ZL at the right side thereof, and be rocked from the depending position shown in said view into the inclined adjustment in diclated in Fig. 3.

In connecting the cord 10 with the reel vblock 12, the clamping block 12c is removed and the cord is embedded in the recess fZ;

` the block 12c is now seated on the portion of the cord thatoccupies the recess and is thereon clamped by replacement of the screw bolt e. Preferably the cord is engaged with the reel body near the center of length of said cord, so that one portion thereof extends downward and the other portion upward therefrom. The ends of the shaft 13, which project beyond the flanges 12b, are squared as at p for engagement with socket formations ]0 on a guard frame 16'. The guard frame in the present construction thereof, is formed of two heavy wire members that at their centers have the socket boxes p secured thereon and are thence extended oppositely, the end portions thereof being bent toward the cord 10 and coiled loosely around said cord, as is indicated at r in Fig. 2. It will be seen that the cord 10, when pendent from an overhead support, will be guided toward the reel body by the end portions r of the frame 1G, so that the upperl and lower portions of the flexible connection will be adapted to wrap evenly upon the reel body 12 first and then upon the lateral extensions 12a thereof.

In the present construction of the device, the reel body 19. and lateral extensions 12a thereof, must be rotated in the direction of the arrow in Fig. 6 to coil the spring 14 i tui-n the body 12 -so as to threw the pawl Z into the inclined position shown in Fig. 3. The free Vend of the pawl Z is caused by the tension of the spring 14, to engage with a lug Zt on the abutment block h, over which the toe of the pawl has slid, which engagement will hold the spring from uncoiling and the lamp 11 suspended from the ceiling in lowered condition. To release the cord, a slight pull thereon will correspondingly further wind the spring so as to dispose the pawl Z iirst in the position indicated in Fig. 4, releasing the spring so that it will uncoil somewhat and wrap the cord upon the re'el body. Upon checking the wrapping of the cord by grasping it t-ightly after it has been shortened a desired degree, the pawl Z will again interlock with the lug Zi on the Aabutment block the pawl has been engaged with, or either of the other lugs it may be nearest to, and thus the lamp will be held stationary at a desired height.

lVhile the preferred use for the improved hanger is the controlled suspension of an electric lamp, it is obvious that it may also be employed for hanging another type of lamp, and be equally as serviceable.

Slight changes may be made in the constructive details of the improvement within the scope of the invention; as for example, sheet metal may be substituted in 'the ceristruction of the guard frame 16, which may partly or entirely inclose the lia-nger mechanism; further, the lugs ZL may be placed on the opposite end of the abutment blocks 7L and the spring reversed in position, which will adapt the device to wrap the two portions of the cord oppositely on the reel block.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
