vSWING FOR ELECTRIC-LIGHT OR TELEPHONE BRACKETS.

SPECIFICATION forming part of Letters Patent No. 567,550, dated September 8, 1896. Application filed November l5, 1895. Serial No. 569,065. (No model.)

To (MZ A117mm it may concern:

Be it known that I, ALBERT PETEREIT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Swings for ElectricLight or Telephone Brackets and Similar Devices, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, in which- Figure l is a side elevation, with parts broken away, showing construction in section. Fig. 2 1s a side elevation of the male nipple. Fig.

is a side elevation of the female split nipple. Fig, 4 is an end view of the same. Fig. 5 is a sectional view of the lock-nut. Fig. 6 is a top or plain view of the telephone-transmitter bracket.

The object oi' my invention is to furnish. a swing which maybe adj usted to revolve easily, with increased resistance, or one which may be set or locked in any positive predetermined position and the lever or handle removed to prevent a novice or one not familiar with the device from tampering with it and getting.

it out of order. W hen swinging brackets of ordinary construction are placed on partitions, desks, or other places which are not ri gid and susceptible to vibration,the bracket is liable to be moved accidentally, and some means must be provided for quickly locking and unlocking it, and such means is provided by this invention, which makes the bracket movable or stationary, as may be required or desired, at will.

In the accompanying drawings, A is a back plate into which the socket-support B is secured.

C designates a Vhollow externally double compressible screw-threaded nipple which secures a quick adjustment. The nipple is slotted,as shown in Figs. 3 and et, at a, and has a clear smooth beveled edge Z) at the top. This nipple is secured to the support B and is encircled by a lock-nut or compressor G,thread ed internally part of the way up to correspond with the double screw-threads on the nipple upon which it screws. It may be provided with one or more handles C2. This lock-nut has a smooth beveled portion near its upper edge on the inside to correspond with and inversely to the bevel on the top of the nipple, as shown at c.

E designates a male nipple forming the b'alance of the swing, slightly tapering,its largest diameter being at the bottom. This tapered end fits into the upper end of the nipple C and has a shoulder which rests on the upper end of the nipple C. A tube F is fitted into the side or top of the male nipple E, and when the end nozzle or other finishing-piece is secured to the free end of the tube the bracket is completed. 1When the lock-nut is quite loose,the joint will revolve freely,but cannot be accidentally displaced. Then it is desired to have it remain in any position in which it is left, the lock should be slightly tightened, which is done by screwing the lock-nut C' down slightlyon the threaded nipple C. The upper end of the nipple C will be closed by reason of its'beingpeveled at the top and coming' into contact` with a corresponding bevel on the top at the inside of the lock-nut, and the slots will enable the parts to be brought together-,Creatin g friction on the tapered sides of the section E, which cannot then be lifted out or removed, and when the lock-nut is tightenedstill more the friction is so great that the joint ceasesr to rotate and will stay in any position in which it may be left. YVhen it is desired to leave the bracket .in a iiXed position permanently and the proper friction to make the joint swing nicely has been obtained by the adjustment of the lock-nut, the handle or handles may be unscrewed and removed, as the screw-threads which are shown at G will permit, and then the lock-nut cannot be moved except by tools or by replacing the handles.

It will be readily understood that this invention is adaptedto be used with vrequal facility in transmitter-brackets for telephones. The swing and locking device operate equally as well in either a vertical or horizontal position.

It may be readily and easily wired by taking out the tube and swinging the part E and drawing the wire through, leaving sufficient wire free to pass down into and through the IOO back plate. 'Vlhe section 'E is then put vin place and the leek-nut tighte1'1ed and the braeket adjusted. as desired.

IIaving described the objects, uses, and advantages otf my invention, what I believe to be new, and desire toseeure by Letters latent otl the United States, and what l therefore claim, is-

l. As animprovement in swings li'oreleetrie lights and telephones, a joint, consisting ort.' a slotted hollow main seotion or soeket; Vin oombination with a renmvable section adapted to be supported in the tirst section7 one ot' said seetions provided with a shoulder forming a bearing-surfaee,tor supporting the second seetion vertically, and a Compressor t'or eompressing the slotted. nipple around and upon the seetion which is secured Vwithin the lower seetion, substantially as deseribed.

A main support provided with athreaded slotted nipple tapered at one end, in eombination with a lock-nut eorresijiondingly and inversely tapered on the inside and adapted to compress the slotted nipple to lock the tixture in place with a straight-sided, non-serewthreaded removable seetion or iixture provided with a shoulder abutting against the outer end ot:- the slotted nipple and. being depressed at a point below the shoulder and within the plane ot' a line drawn from the outer periphery oli' the shoulder to the outer periphery oli' the movable seetion below the said depression, and adapted to iit revolubly within the slotted support, and adapted to be revolved an unlimited number oi times in one direction and in the same `horizontal plane, said removable seetion fitting snugly against the inner wall of the slotted section below and smaller than the inner diameter of the slotted section at and near the top oi' the split section., substantially as described.

I3. As an improvement in swings :l'or eleetrie lights and telephones, a main supiriort; in i eo111bination with a slotted nipple, tapereill at its upper end and a lockamt eorrespondingly ltapered on the inside and encircling the slet ted nipple and a supplemental plug, having a shoulder whieh :rests on the top ot' the slotted nipple, the supplemental plug extending into the slotted nipple7 substant'iallyr as and for the purposes speeilied.

-;I-. As an improvement in swings t'oreleetrie lights and telephones, a main support provided `with a coinl'iressible nipple having a break in its outer end and screw-threaded exteriorly; `in Combination with a lock-nut adapted to embrace said nipple and to eompress it at its outer end by being turned upon it and a tapered supplemental nipple, having a shoulder which rests on the eompressible nipple, adapted to support the trans111itter or light arm, substantially as described.

Asanimlrnovement inswingingsupports lor eleet ric lights and telephones, a main support, externally threaded and provided with a split ni pple, the upper outerportion oi which is smooth and inwardly tapered and an i11- teriorly-tl1readed lock-nut having a smooth tapered surface, adapted to engage and cont press thel s111ooth tapered sections oi the split nipple7 for lessening thediameter ot" the nipple to look the arm olf the swinging supportV at any desired point and against aeeidental displaeement at all times; .in combination with a second section whose outer eireinni'erenee at the top is less than the inner normal eireumt'erence of the split section, leaving a space between them, said second section adapted to [it snugly within the split nipple, below the top, substantially as described.

In testimony whereof I at'tix my signature in the presence of two witnesses.
