To all whom t may concern.'

Be it known that I, FRED MAEQUART, citizen of the United States, residing at Sandusky, in the county oli-ErieandfState of Ohio, have invented certain new and useful Improvements in Adjustable Revolving Display-Racks, of which the follow-ing isla specification.

This invention relates to display racks of that type suspended from ceilings and eX- tensible to permit the rack to be raised or lowered, by means of telescoping tubular sections, and has particular reference to the means for supporting the lower section or tube in vertically adjusted position, said means including a wedge lock, acting to hold a tape which supports the adjustable section of the hanger, the lock being manipulated by means of a knob at the lower end of the rack. The rack is also supported in such manner that it can be rotated.

In the accompanying drawings,

Figure 1 is a side elevation of the rack.

Fig. 2 is a central vertical section Ot' the ceiling bracket, containing the ball bearing on which the rack rotates.

Fig. 3 is a top plan of the bracket.

Fig. 4: is a longitudinal section showing the locking devices.

Fig. 5 is a similar section at a right angle to Fig. 4.

Fig. 6 is a cross section on the line 6 6 of Fig. 5.

Secured to the ceiling 7 is a tubular bracket 8 having, on the inside, a number of lugs 9. 10 is a tube forming the upper section of the hanger, and this projects at its upper end into the bracket 8, and has xed thereto upper and lower rings 12 and 11, between which iits a ring plate 13, races being formed in the rings 12 and 13 for the balls 1d. The ring plate 13 has lugs 15 projecting outwardly to engagement with the lugs 9, to which they are iiXed by pins 16. The rings 11 and 12 prevent any vertical movement of the tube 10, which however can rotate on the ball bearing, the weight being supported by the fixed ring plate 13.

A lower tube 17 telescopes over the upper tube 10, and secured to the tube 17 are one or more brackets 18 with arms 19 upon which the articles to be displayed are placed.

An endless steel tape 20 is attached to the tube 10 near the lower end thereof, conveniently by means of a boss 30 which confines a link 31 connecting the ends of the tape, which passes through slots 32 in the boss, the slots being too narrow topermit the passage Off-the link. This steel tape yormsthe connection between the tube sections 10 and 17 and supportsfthe latter in adjusted position. The tape is bent `or looped vover a locking or wedgey block 21 at l its lower end, and over an upper roller 23,

the block and roller being mounted between the side bars 22 of a frame, the bars being spaced apart by pins 27 which have rollers 26 thereon to guide the tape. The .trame is located within the tubes and is movable up and down therein. The block 21 is pivoted near its upper or narrow end, to the side bars of the frame, by means of a pin 28, and in order to limit the lateral motion of the locking block aV pin or rivet 29 extends between the side bars and through a hole 30 in the block somewhat larger than the pin. A knob 37 is secured to the lower ends of the side bars 24 by means of a rivet 32. l/Vithin the lower end of the tube 17 is a iixed collar or plate 33 having a central square opening 34. This collar is located or extends around the block 21, in such position that the tape may be gripped between the edge of the collar and the sides of the locking block, to hold the parts at adjustment.

In operation, the weight on the tube 17 causes the edge of the collar 34 to grip the taperagainst the block 21, thus supporting or holding the tube 17 in adjusted position. To release the tube the knob 37 is given a slight jerk or pull downwardly, thereby releasing the grip on the tape 20, and the tube can then be raised or lowered, the tape running ree over the block 21 and the roller 23. To stop the movement, the knob 31 is given a quick push upwardly, to again clamp the tape between the block and the collar. The tubes can be easily rotated on the ball bearing as desired. The action ot the adjusting devices is practically noiseless, and the use of counterweights is unnecessary. The slight shift of the frame 22 and tape 20 in the action of locking or releasing the tape is permitted by the loose connection of the tape to the tube 10 aorded by the elongated boss 30, in which the link 31 is slidable to a limited extent. The invention is not limited to the special form shown but is capable of various embodiments.

What I claim as new is:

1. In a hanger, the combination of upper and lower telescoping tubes a tape connected to the upper tube, a frame within the tubes, over which the tape runs, and releasable means to grip the tape between the frame and the lower tube.

2. In a hanger, the combination of telescoping upper and lower tubes, the lower tube having an inner collar, a tape connected to the upper tube, a frame adjustable within the tubes and over which the tape passes, and a wedge block carried by the frame, the tape passing between the block and the collar, and the frame being adjustable to grip the tape between said block and collar.

3. In a hanger, the combination of upper and lower telescoping tubes, a tape con nected to the upper tube, a frame movable within the-tubes and provided with a handle projecting at the lower end of the lower tube, and a wedge block pivoted to the frame and around which the tape passes, the frame being adjustable to lock the tape between the block and the Vinside of the lower tube.

In testimony whereof, I d0 aflix my signature in presence of two witnesses.
