DISPLAY RACK.

Application filed April 20, 1923. Serial No. 633,465.

My invention relates to a display rack, and more particularly to a display rack adapted to be employed in connection with chenilles carpets, canvas and goods of a similar character.

The chief object of my invention is to provide an improved display rack in which goods of the character described may be the character described in whichmeans are provided for preventing rotation of the roll carrying members 111 one direction, in

the opposite direction, and in both irections; which comprises mean forguiding the goods so that compact rolls of aligned layers of the goods may be obtained, and which comprises brake means for controlling the speed of rotation of the rolls so that the inertia of the rotating roll will not cause more goods to be unrolled than is desired.

Other objects of my invention will become apparent as the detail description progresses, reference being had to the accompanying drawings, wherein Fig. 1 is aperspective view of an improved display rack embodying the novel features of my invention. v

Fig. 1% is aisectiongtalien on line i k-14 Similar characters of reference designate similar parts throughout the several views.

Referring to Fig. 1, the reference characters 10 and l O designate two frame menibers or standards, which are employed to support and carry a plurality of tubes 11, upon which goods such as chenilles and broadlooin carpets r ay be rolled in com pactform. The standard 10 comprises a pair of inclined leg members 12 and a cross brace 13. Each of the leg members 12 is provided with a foot 14 so proportioiied'that the standard may remain in upright position without securing it-to the floor means of bolts or. other fastening means. However, I provide a plurality of ape/r tured bosses 15. in each of the feet 14, and if so desired, the feet may be secured to the floor byni'eans of bolts passed through the bosses. The standard 10 comprises leg members 12, a cross brace 13 and feet lat of identical construction with the similarly desard 10 comprises a bearing bracket 16rigidly secured to the standard 10 bybolts 17. A plurality of anti-friction rollers 18 rotatably journalled in the bearing bracket 16 are adapted to rotatably journal one end of the particular tube 11 associated with the particular bearing bracket 16. To prevent accidental displacement of the tubes relativeto'the bearing brackets 16 each of the bearing brackets is provided with a yoke 19 detachably secured to the bearing bracket by means of machine screws 20. The antifriction bearings rotatably journaling the tubes 11 upon the standard 10 comprise a plurality of bearing blocks 21 rigidly secured to the standard 10 by bolts 22 (Figs.v 1, 2, 3 and 43). Each bearing block 21 has a central bore 23 adapted to receive the outerrace 24 of a combined thrust and radial ball bearing 25, the inner race 26 of the ball bearing having driving engagement with a stud shaft 27. The stud shaft 27 is rigidly secured to and in one end of one of the tubes 11 by means of a pair of collars 28 and pins 29, the axes of the stud shaft 27 and its associated tube 11 being coincident (Fig. 4-). The outer end of each stud shaft 27 is squared as at 30 to fit the socket 31 of the crank lever 32, which may be applied to any one of the stud shafts 27 to rotate that stud shaft and its associated tube 11 to roll or unroll goods upon or from the tube.

. A ratchet 33 is rigidlv secured to each of the stud shafts 27 by means of a set screw 34, the ratchets 33 being disposed adjacent the outer faces of the bearing blocks 21. A pawl 35 is provided for each'of the ratchets 33, each pawl 35 being slidably mounted in one of a plurality of lugs 36 formed integrally with the bearing blocks 21. Each pawl 35 is provided with a hand piece 37, a cylindrical portion 38, a shoulder 39, and a beveled surface 40. The cylindrical. portions 38 of the pawls 35 are adapted to fitsnugly in squared apertures 41formed in the lugs 36, the shoulders 39 being adapted to rest upon the upper surfaces 42 of the lugs 36 or in slots'43, one of which is formed in' each of the bearing blocks 21 (Figs. 2, 3, 6 and 7). A cotter pin 44 is provided for each of the pawls 35 to prevent withdrawal of the pawls from the lugs and subsequent loss thereof.

Referring now to Figs. 2 and 3, it will be noted that the pawl 35 has its shoulder 39 resting upon the right hand portion of the surface 42 (Fig. 2), and that it will lock the tube 11 against rotation in a coun ter clockwise direction (Fig. but will permit the tube 11 to be rotated in a clockwise direction (Fig. 3). It is also apparent that if the shoulder 39 of the pawl 35 be shifted to rest upon the left hand portion (Fig. 2) of'the surface 42, the pawl 35 will prevent rotation of the tube 11 in a-clockwise direction (Fig. but that the beveled surface 40 of the pawl will permit the tube 11 to be rotated in a counter clockwise direction (Fig. Also, if the shoulder 39 be shifted to rest upon the forwardly extending portion of the surface 42, the beveled edge 40 of the pawl 35 will not be in a position to cooperate with the ratchet 33. The cylindrical portion 38 of the pawl will then look the'ratchet 33, stud shaft 27 and tube 11 against rotation in either direction. The pawl 35 maybe removed from engagement with the ratchet 33 by placing the shoulder 39 in the slot 43 which is formed in the bear ing bracket 21. When the pawl 35 is so withclamp 45 and the cylindrical surface of the.

tube 11. The screw 46 may then be tightened until the clamp 45 securely holds the article in place. When one edge of acarpet or the like has been secured to a tube 11 by means of the clamps 45,.the tube 11 may be rotated through the medium of the crank lever 32 and the carpet wound compactly about the tube 11. The tube 11 may then be locked against rotation by means of its associated ratchet and pawl 35.

To guide the carpet when it is Wound upon one of the tubes 11', and so as to form a compact roll havingaligned layers, each of the tubes 11 is provided with a pair of guard wheels 47, a guard wheel 47 being disposed adjacent each end of the tube 11. Each of the guard wheels 47 is adjustably and frictionally secured to its associated tube 11, the guard wheel being constructed of two separable, identical halves, as shown in Figs. 1, 3 and 12. The separable halves of each guard wheel 47 are secured to each other by bolts 48 which pass through split spokes 49 of the guard wheel at points ad-' jacent the split hub 50 of the guard wheel. Each split hub 50 of the guard wheels 47 comprises a plurality of contact points 51 which are adapted to frictionally engage the outer cylindrical surface of the associated tube 11 when the two halves of the guard wheel are drawn together by means of the bolts 48. It is readily understood that any one of the guard wheels may be adjusted longitudinally of its tube 11 by relieving the tension upon the bolts 43 and sliding the guard wheel to a new position. The guard wheel may then be clamped in its new position by means of the bolts 48.

In the devicewhich I have shown in the drawings, I prefer to use the guard wheels 47 adjacent the standard lO-as means, together with brake shoes 53, for controlling the speed at which the tubes 11 rotate when the carpets or other goods are being withdrawn from the tubes 11. I have learned that the weight of the material which is being,

withdrawn from a roll of goods is sufficient to cause the roll and its associated tube 11 to spin. Therefore, I have provided the brake shoes 53, having fabricated linings 54, which may be brought into frictional engagement with the guard wheels adjacent the standard10. As shown in Fig. 1 the brake shoes 53, which are associated with those tubes 11 having ends journaled in bearings on the inclined leg members 12 r and also with the uppermost tube 11, are

arranged in pairs. The brake shoe 53 which controls that tube 11 having one of its ends journaled in a bearing on the cross brace 13 is pivotally secured to a lever 55. The lever 55 is rigidly secure? toa shaft rotatably journaled in a bearing 57 secured to the cross brace 13 bymeans of bolts 58. The shaft 56 is disposed parallel to the tubes 11 and has its outer end squared as at 59 to receive the socket 31 of the crank lever 32, which may be employed to operate the brake means as well as to rotate the several tubes 11.. I

Of the brake shoes which are arranged in pairs, each brake shoe of a pair is pivotally secured to a lever 60 by one of a plurality of pins 61 (Fig. 3). Each of the levers 60 is rigidly secured to the inner end of a shaft 62 ro-tatably journaled in a bearing 63. each bearing 63 being secured to one of the inclined legs 12 by bolts 64: 64. The outer end of each of the shafts 62 is squared to receive the socket 31 of the crank lever 32, and by means of the crank levereither one of eachpair of brake shoes 53 maybe brought into frictional eng? nnent with its associated guard. wheel 47. 1 v

Vhile I have shown the brake shoes engaging certain of the guard wheels 17, it is apparent that if it weredesirable to move these guard wheels toward the center of the tubes for guiding goods upon the tubes, ad

ditional guard wheels of identical construction could be placed upon'th-e tubes in alignment with the brake shoes to permit opera tion thereof. 7

In the operation of the device, one edge of a carpet or the like is secured to one of the tubes 11 by means of the clamps 45 in the manner aforesaid. By use of the crank lever 32 the operator may then rotate the tube 11 until the carpet is wound upon the tube in a compact roll, the guard wheels 47 serving to keep the side edges of the carpet in alignment with the roll. When the car pet or the like is to be displayed or removed from the tube 11, the crank lever 32 is associated with the particular brake shoe 53 controlling the tube 11 upon which the carpet or the like is wound. Then as the carpet is being withdrawn from the tube 11, the operator may check the speed of rotation of the tube 11 by varying the pressure with which the brake shoe 53 engages one of the guard wheels 17 carried by the tube. The carpet may be rewound upon the tube by placing the crank lever 32 upon the squared end 30 of the stud shaft 27 carried by the tube 11 the operator simply rotating the tube 11 in a proper direction. Of course the pawl 35 may be employed to lock the tube 11 against rotation in both directions when the display rack or that. particular tube 11 is not in use, and to lock the tube against rotation in one] or another direction when a certain length of goods has been withdrawn from the roll and it is desired to prevent further rotation of the tube.

In Figs. 13 and 14- I have shown a modilied form of hearin which may, be employed to rotatably journal the carpet carrying tubes. As shown, a tube 11 having a clamp 45 adjustably secured to the tube by a machine screw 46 has one end rotatably journaled in a bearing 21. The bearing 21 is rigidly secured to a standard 10 by bolts 22 Rigidly secured to the outer end of the tube 11 which projectsbeyond the bearing 21, is a ratchet 33 adapted to cooperate with a pawl 35 pivotally secured to the hearing 21 by a pin 35. The free end of the pawl 35" is bifurcated to provide two teeth 35 and 35 hen the pawl 35 isin the position shown in full lines in Fig. 14. the tooth 35 is adapted to engage the ratchet 33, and to prevent rotation of the tube 11 in a counter clockwise direction (Fig. 14),

.but to permit rotation of the tube 11 in a clockwise direction (Fig. 1 1). If the pawl 35 is shifted to occupy the'position shown by dotted lines in Fig 1 1 the tooth will engage, the ratchet 33'? and prevent rotation ofthe tube 11* in a clockwise direction (Fig.

1 1) and permit rotation of the tube 11' in a counter clockwise direction: (Fig: 1%).

A. collar llfis rigidlysecuredupon the tube 11? by a set. screw 1 1 the collar being disposed adjacent the inner face of the bearing 21*. The collar 11 and the ratchet 33 cooperate tohold the tube 11" against longitudinal displacement relative to the hearing 21 A longitudinal groove 21 is formed in the inner cylindrical bearing surface of the bearing 21. Disposed in the groove 21 and. slidably journaled therein is a brake shoe 53 having a fabricated lining 54 adapted to frictionally engage the outer cylindrical surface of the tube 11*. The force with which the brake shoe 53 and its lining 54c engage the tube 11 may be; regulated by means of a pin 53" threaded into the bearing 21 and adapted to engage the brake shoe 53. A handle 53fis secured upon the outer end of the threaded pin 53 so that the operator I claim:
