2 A vstill further object of my invention is |to show a magazine retainer or holder which is made up of four walls and a bottom element and which may be readily assembled or knocked down for transportation purposes;
Other objects, and ancillary advantages inherent in my invention will lbecome apparent from an examination of the accompanying drawings, bearing lfurther elucida- .tion in the ensuing description, wherein like symbols are used to designate like parts, and in which;

. sold in knocked down position to occupy a minimum of transportation space and involve a minimum of expense, and which may be readily set up by the purchaser when brought to the destination where the article is to be ernployed.
Fig. 9 is a cross-sectional view taken substantially on the lines 9-9 of Fig. 81 Y Fig. l0 is a perspective view4 of a magazine rack manufactured in accordance with the practices expounded by my invention and has certain portions thereof broken away and enlarged in order to more clearly deline the specific elementalstructure thereof.
Fig. 11 is a transverse cross-sectional view 4showing how my invention may be employed for manufacturing tubular structures. p
Fig. 12 is a fragmentary view showing how my invenytion may be employed for manufacturing tubular structures which have an outer smooth perimetral contour or configuration.
Fig. 13 is a slightly modified form ofl my invention showing how it may be employed forf the production of tubular or pipelike structures having an offset tooth e11- gaging means cooperating with resilient lip means to releasably engage opposite edges of a quadrilateral resulting in the Aformation of a smooth outer perimetral conguration.
Referring to Figs l, 2 and 3, the preferred form of my invention is, generally, designated 14, and consistsof two sheet like elements 15 and 17, one ofthe elements, namely 15, being providedV with `an angular ilange 16 which cooperates to forma locking space with the angle iron element19, shown as havinga multiplicity of right angularly relatedledges 21 terminating in, substantially, right angular locking lips 22. Theelement 19,is spot welded toV the element 15l at 20, Aas indicated, or it maybe secured by rivets or otherIiiushf fastening means. The element 17 is provided with a hem-like portion 18 folded over on itself in order to provide the locking edge 23 which is engageable by the locking lips 22 and which, are regularly 'spaced as indicated alt 24. It is to be noted that'the con- -tinesV between the angular portion 16 and the locking Aledges 21 is, substantially, of the same dimension as the thickness of the element 17 and the hem portion 18 cornbined.
Y Thus the elements 17 and 15 may be snapped out of engagement to be transported in knocked down position or may be readily snapped into engagement by forcing the rounded beaded edge 18 to assume a position between the locking lips 22 and the angular portion 16. p
TheV modification indicated in Fig. 4 is, generally, designatedl 25, and it indicates how the element 17 is pro- Avided with its hem portion 18 whereas the element 15 is provided with the angular portion 16 andthe locking 'means in this instance 26 is spot welded at 27 and consists of a continuous ledge 28 having a continuous lock- Ving lip 29 to engage the locking edge 23 on the hem portion 17S. VThe unit will afford greater rigidity and may be utilized for heavy duty construction. Fig. 5 shows a slightly modiied form of my invention kdesignated 80 consisting of an element 81 having the angular portion 82 whereas the mating element 83 is provided with double hem portions 84 and 85 so as to provide the beaded engaging edge 86 to be releasably engageable by the locking lips 22 of the element 19 so that the locking lips 22 may be employed to releasably retain the beaded edge 861. Fig. 6 is similar to the construction Vindicated in Figs. l, 2 and 3 with the exception that the hem section 18 `is odset as shown at 87 so as to provide a flush exterior `between the angular portion 16 and the element 88.
Fig. 7 indicates wood or other thicker materials designated 34 and 35 the modilication being, generally, designated 29' wherein an angle iron element having angular `portions30 and 31 is secured to the element 35 by means of screws 32 and 33 furnishing an extension between which is conlined the element 34 land which has secured 'thereto a cooperative locking element 36 having ahem Aportion 37 and having the clearance hole 39 so as to permit a screw 42 to fasten the same to the element 34 by means of the countersunk opening in the element 36. 'Resilient locking means 41 is secured by screw 42 to Y element in proper distance so as to permit the confines of the composite elements 34 and 36 to be releasably engaged by the locking lips 44 of the ledges 43 of the element`41. The hem portion 37 thus furnishes the locking edge 38 which is releasably -engageable by the re- Vvsilient locking lips 44. j
Modicationsfor the manufacture or production of tubular or pipe-like structures is indicated in Figs, 1l, l2 `and 13. In Fig. ll it will be noted that the tubular structure, generally, Vdesignated 45 has opposite ends 46 and ,52 thereof secured in offset relationship by means of a lockingr edge 54 on the hem portion 53 whereas the element-47 which is spot welded at 49 near the end 48 is provided with an offset ledge portion 50 providing the locking lip 51 which releasably engages the locking edge k54 on the hem-like structure on end 52. r In'order to provide a smooth perimetral or outer configuration to a tubular structure it may be made as indicated in Fig. l2 wherein the end 52 cooperating with the v end 48 when brought about in meeting relationship releasably secures those two ends by means of an offset portion 55 which secures the hem-like portion 56 on the end 52, whereas the element 47 with the offset ledge 50 and the locking lips 51 resiliently andl releasably'retains the locking edge 57 on the hem 56 confined by the resilientflocking lips 51. The modification indicated in Fig. 13 shows an oset tooth portion 58 on the endv 52 forming a locking tube which is releasably engageable by the locking lips 51 of element 47.1 v
Yrelated locking flange portion, and angle .and in parallel relationship to said locking An example of the practical utility of my invention is incorporated in a magazine rack illustrated in Figs. 8, 9 and l0. Referring to Fig. 8 which is an exploded View it will be noted that the ends 60 and 61 are provided with the element 77 secured so as to permit the ledges 78 to be suitably spaced from the angular portion 76` and further extending to form locking lips 79 which will engage the hem portion 75 on the side wall 62. The` side walls 62 and 63 are ,provided with reinforced hems 74 and 75 which tend to reinforce the wall structure, generally, and are provided with continuously curled oppo= site edges '66 and 65 which form the handles of the maga zine rack, whereas the rolled or curled portions 67 and 68 provide the legs or resting supports for the magazine rack.
it will also be noted that the walls 62 and 63 inter;
rrnediately and closely adjacent to the foot or support portions 67 and 68 are provided with folded over: beaded portions 69 which are engageable by the prongs 71 offset with respect to the ledge `portions 70 on the bottom ele- `ment 64. `This modified form of my invention generally,
designated 59 therefore can be sold in knockeddown arrangement consuming very little space so that purchasers who customarily would buy these items in knocked down arrangement in crowded business localities may carry them home conveniently on a train without having to carry the bulk which would have to be carried if the item were not of knocked down construction and occupying the space volumetrically indicated in Fig. l0.
ln assembling the unit the bent beaded formations 69 are assembled with the bottom 64 thus assembling the side walls 62 and 63 with the bottom 64. The end walls 61 and 60 are then snappedtinto assemblyvand as indicated are made of ornate configuration so as to provide also an attractive design to the magazine rack being reinforced at 72 and 73 for strengthening the product.
The arcuately extending edges at the top and bottom Aof the end walls 60 and 61 thus have the province of `furnishing an abutment for the edges of the bottom element 641 and conceal the same from View providing a finished or artistic construction simultaneously providing additional rigidity thereto.
also be employed astindicated in oneof the modiiied forms illustrated. Other modifications and changes in the materials and in the structural details may also be Amade provided they are within the scope of the appended Yclaims and without departure from the spirit of the in- ;Vention.
