SPECIFICATION forming part of Letters Patent No. 417,608, dated becember 17, 1889.

Application ined August 2, 1889. serial No. 319,551. (No model.)

To @ZZ whom it 17m/y con/cern.-

Beit known that I, NEWTON H. TRAVER, of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Oarpet-Display Rack, of which the following is a full, clear, and exact description.

My invention relates 'to an improvement in display-racks for carpets, oil-cloth, shadecloth, ctc., in salesrooms, and has for its object to provide a device of simple and durable construction to which the material may be attached in rolls drawn from the device in lengths as required for display or sale and automatically rewound When'desired.

A further object of the invention is to provide a means whereby less floor-room will be required for the display of the goods, and wherein the rolls will require handling but once, and also wherein a maximum amount of vertical space may be utilized.

The invention consists in the novel construction and combination. of the several parts of the device, as will be hereinafter fully set forth, and pointed out in the claims. Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a frontelevation of the device. Fig. 2 is a horizontal section through the supporting-beams, the device being shown in plan view. Fig. 3 is a side elevation. Figs. 4 and 5 are detail views of the rewinding mechanism, and Figs. 6 and`7 are detail perspective views of portions of the brackets. Fig. 8 is a plan'view of a slightly-modified form of the device. Fig. 9 is a vertical Section through the rewinding mechanism of the same. Fig. 10 is a side elevation of the rewinding mechanism,I and Fig. 11 is a side elevation of one bracket detached.

The standards 10, adapted to support the device, are preferably made in girder shape or of I-bars provided with ratchet-notches 11 upon one face in the edges of their iianges, the 'said standards being introduced at the Ybase into short sockets 12, secured to the fioor and into long sockets 13, attached to the ceiling, whereby the standards may be readily adjusted to rooms of varied or varying heights. The standards are arranged at suitable distances apart and in horizontal alignment, and upon the fianges of each ,Standard a bracket is held to slide, two brackets 14 and 15 forming a portion of each device. The brackets are essentially alike in construction, each bracket comprising a body portion a, having an outwardlyextending arm o. integral with the lower end, the upper portion a2 being considerably wider than the surface immediately above the arm. lAt top and bottom of the rear edge of the body an essentially L-shaped lug 16 is cast, extending inwardly and vertically beyond the edges, and a perpendicular rib 17 is formed upon the inner end of the arm a', and in the upper portion of the body an opening 18 is produced, surrounded at the bottom and sides by an essentially U-shaped flange 19, having inclined inner faces, the inner perpendicular member whereof is in a vertical plane with the arm-rib 17. (See Figs. 3 and 6.)

The inner surface of the bracket-bodies between the lugs 16, the rib 17, and aligning member of the U-ange 19 is adapted to slide upon the outer face of the standard-fianges,

and when in this position they are held to place by the lugs 16 contacting with the inner faces of the standard-flangesat the rear, and a key 20, introduced into the bracketopening 18, contacts with the corresponding face of the standard-flange at the front, or that portion of the fianges containing the notches 11, as shown in, Fig. 3. The key 20 is illustrated in detail in Fig. 7, and comprises a body l?, of suitable shape to slide over the opening 18 into the U-iiange 19,and when in this position it is wedged to place, an offset b ,integral with the lower end, fitting over the fiange, and a rearwardly-extending finger bzrcontacting with the notched standardflanges, as aforesaid. The lugs 16 are first made to contact with the standards, and then the key is inserted.

It is obvious from the foregoing description that the brackets may be expeditiously and conveniently detached from the standards whenever desirable by removing the key. The brackets are locked to the standards at various points in the height of thc latter by pawls 21, weighted at their forward ends, one of which pawls is pivoted upon the lower por- IOO tion of the section a2 of each bracket immediatelybencath the U-fiange 19, as shown in Fig. 3, and enters the notches ll of the standards. The weighted ends of the pawls serve to retain the inner ends in normal engagement with the standards and also afford a handle for disengaging the pawls.

In the upper edges of the section d2 of the left-hand bracket l5 a recess 22 is produced, which recess is adapted for the reception of one end of a reel-shaft 23, the bearing for this end of the shaft being completed by pivoting to the inner face of the bracket a locklever 24, recessed in that portion of the lower edge spanning the recess 22, as shown in Fig. l2. The lock-leveris limited in itsdownward movement by a stirrup 25, integral with the bracket, and is normally retained in contact with said stirrup by a spring 2G, as shown in Fig. l, which spring also acts as a brake to prevent the revolution of the reel-shaft unless the same is properly revolved. The bracket it differs only from the bracket l5 in that the lever 2l and s1irrup 25 are omitted, and the body projection a2 is higher and provided with a circular opening for the reception of the reel-shaft, and a rear projec tion ai" is integral with the top of the body, as shown in Fig. 23. The reel-shaft 23, journaled in the brackets, is provided at the lefthand end with two or more annular grooves 27, adapted to receive the lock-lever, whereby the shaft ymay be shifted from Lright to left, and vice versa, and held in the shifted position.

Upon the shaft 23, between the brackets at the right-hand end, a spur-wheel 2S is secu red, and at each side of the center a disk 29 is adjustably mounted upon the shaft, provided with a series of pins 30 upon the inner face, between which disks the roll of carpet, oilcloth, or other material is held, the pins entering between the folds.

Upon a spindle secured to the inner face of the right-hand bracket as a drum 32 is loosely lnounted, containinga coil-spring 3.3, as shown in Fig. 5, one end of which spring is attached to the spindle and the other end to the inner peripheral face of the drum. Upon the outer edge of the periphery of the saiddrum a series of teeth 34 are formed, adapted to mesh with the spur-wheel 2S of the reel-shaft, and upon the outer face of the drum a pawl 35 is pivoted, having projected from opposite sides of its head horns 36, as shown in Figs. 4 and 5, adapted to be engaged by a strap-spring 37.

Upon the inner face of the rear projection c3 of the bracket ll an arc-shaped projection 3S is formed, the concave edge being upward, and upon this edge a series of ratchet-teeth 39 are produced, as shown in dotted lines, Fig. 3, and in section, Fig. 5. The pawl 35 of the drum during a portion of the revolution of the latter contacts with the ratchetteeth.

The operation is as follows: lVhen the carpet is drawn downward to unroll the same,

the pawl being in the normal position illustrated in Fig. 3, the drum is, by meshing with the reel-shaft gear 2S, forwardly revolved, thereby winding up thespring, and as the pawl approaches the ratchet-teeth 3*.) it is thrown in position to contact with said teeth, as illustrated in Fig. l', by the spring 37 acting upon one of the horns, whereby, while so contacting, if the reel-shaft ceases to revolve the drum will be locked in position. It the drum continues to revolve until the pawl passes the toothed arc 38, the spring 37, press` ing forward against the upper horn 36,1estores the pawl to its normal position, whereby, if the hold upon the carpet is released at this point, the expansion of the drum-spring 33 acts to turn the drum rearward, the pawl offering no resistance, as shown in Fig. 5. This latter movement of the drum rcwinds the carpet lupon the roll. It is necessary to guide the carpet in rewinding, and to that end aguide-shaft 40 is journaled upon the arms a of the brackets and provided with a movable sleeve l1, which sleeve is brought in alignment with one of the disks 29, preferably the right-hand one.

Two or more devices may bc placed upon each set of standards, one above the other, and the device is so proportioned that when the brackets contact with the door a roll of carpet having the reel-shaft inserted may be placed in position without beinglifted. After one roll has been placed in the device the latter is elevated as high as desired, and the next device is attached to the standards, dsc. If an upper roll is sold before the lowerone, the brackets of the upper devices are removed, tlie lower rolls elevated, and the brackets again attached to the standards at the bottom.

The form of device illustrated in Fig. 8 is especially adapted for oil-cloth and similar goods which do not require to be drawn off the roll in such lengths and which do require considerable power appliedto rewind. In this construction the drum is mounted upon a sleeve .tl, through which the reel-shaft passes, which sleeve is a portion of the bracket, as shown in Fig. 9, and a clutch-section 42 is formed upon the inner face of the drum for contact with a similar section 43 upon the hub of the spur-wheel 28, and the arc-ratchet projection 3S is produced upon the forward extension a2 of the bracket, as shown in Fig. l0 of the drawings.

If found desirable, the bracket 1l may be constructed in every instance with the sleeve 41 and an arc-shaped projection upon the inner face of both the front and rear extensions c2 and c3, in order that the device may be used interchangeably for carpets and oil-cloth or similar material by removing the drum from front to rear, and vice versa.

When it is desired to unroll quite a length of material, a sale having been made, for instance, in either construction shown the drum may be thrown out of gear with the reel-shaft IOC IIO

by raising the lock-lever 24, sliding the reelshaft to the left, and carrying the lever over out of the groove 27. YVhen shifting the shaft, in order that it may not be carried too far to the left and thereby draw the righthand end from its bearing, anangle-arm b4 is formed upon one of the keys, which limits the shifting movementJ of the shaft by contacting therewith. This angle-arm may also be utilized as a handle to facilitate the removal of the keys.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patentl. In a display rack for carpets and similar goods, the combination, with standards and brackets heldto slide upon said standards, of a reel-shaft journaled in the brackets and a spring-controlled drum connected with said shaft, substantially 'as described.
