Referring now to Fig. 19,28 indicates generally a gluing device whereby suitable adhesive may be applied to a marginal por- I tion of the blank 25. As shown, the blank 25 may comprise two

arcuate edges

30 and 31 and two substantially

straight edges

32 and 33. The edge 33 maybe inserted in a slot 34 formed in the gluing device 28, a stop 35 being provided to insure that the adhesive will be; confined to the proper place upon the blank. The gluing device 28 preferably comprises a container 36 adapted to hold a supply of theadhesive. Pivotally mounted in the container are aplurality of levers, one of which is shown at 37. Secured to the free ends of the levers 37 is a bar 38. A hand lever 40 fixed with re spect to the levers 37 may be employed to bring the bar 38 from the position wherein it is disposed in the adhesive to a position Fig. 17 is a plan view of apparatus for wherein it engages the marginal portion of terial' or the like, but it is to be under-,,

from a description of the apparatus where the embossing or coloring can be done at the invention relates to-a method of and applying adhesive to the blank shown in I Fig.18 is a. section taken on line 18.-18

the blank adjacent the edge 33, when this edge is insertedin the slot 34. Obviously, the adhesive can be quickly and easily applied to the blank.

In Figs. 17 and 18, I have shown a gluing device 42 for applying adhesive to the blank 26. The blank 26 is preferably formed with arcuate edges 43 and 44 and converg ng straight edges 45 and 46, a notch 47 being provided between the arcuate edge 43 and the straight edge 45. In practising the improved method, adhesive is preferably applied along the marginal surfaces which are formed by the arcuate edge 43 and the straight edge 46. The gluing device 42 preferably comprises a housing 48.for holding a supply of adhesive. Projecting upwardly from the bottom wall of the housing 48 is a taper pin 49. The housing 48 is provided with a top plate 50 having a circular opening 51, the opening 51 being disposed concentrically with respect to the taper pin 49 and being of a diameter slightly greater than the diameter of the blank 26. A plate 53 secured to the upper surface of the plate 50 is provided with a substantially circular extension 54 having a central circular opening 55 to accommodate the taper pin 49, the opening 55 having a diameter less than that of the opening 51. A slot 56 extends from the outer edge of the circular extension 54 to the opening 55. Disposed in the housing 48 is a bar 58 comprising an arcuate portion 59 and a straight portion 60. The bar 58 is mounted upon a perforate plate 61 which is suspended from pins 63 secured to a plurality of bars 64 which are in turn secured to a U-shaped rod 65 slidably journaled in lugs 66, the lugs 66 being formed upon the housing 48. The U-shaped rod 65 engages a slot 67 formed in the 'free end of a lever 68 which is secured to a shaft 69 pivotally mounted in bearing blocks 70 secured to the under surface of the housing 48. Rigidly secured to the shaft 69 is a hand lever 71 which may be manipulated to cause the lever 68 to raise and lower the U-shaped rod 65, which will, in turn, raise and lower the bar-58 through the medium of the pins 63 and the bar 64. It will be readily understood that the bar 58 may be brought from a positionwherein it is disposed in the adhesive to a position wherein it lies between the cover plate 50 and the circular extension 54, the straight portion 60 being adapted to enter theslot 56. Hinged to the housing 48 is a circular plate 73 having a handle 74 whereby the late may be brought into a position wherein it covers the circular o ening 51 and the circular extension 54. n practising the improved method the blank 26 is centered upon the taper pin 49 and arranged so that the edge 46 is aligned with the slot 56. The circular-plate, 73 is then brought into the position wherein it is shown in Fig. 18 to press the blank 26 against the circular extension 54. The bar 58 is then brought into engagement with the under surface of the blank 26 to apply adhesive thereto, a relatively narrow band of adhesive being applied adjacent the straight edge 46 and the arcuate edge 43. I

Referring now to Figs. 7 to 11, inclusive,

'75 is a base plate upon which are mounted a plurality of

mold members

76 and 77. The

mold member 77 is fixed to and spaced from the base plate 75 by a plurality of bars 78. The mold member 76 is hinged to the base plate 75, as indicated at 79, and may be swung into and out of the position wherein it is shown in Fig. 9. As shown, the

mold members

76 and 77 comprise frustro-conical walls 80 and 81, respectively, the upper end of the mold member 77 being substantially closed by a frustro-conical wall 82 from which a centering pin or lug 83 projects. A burner 85 mounted upon the base plate 7 5 and disposed within the periphery of the mold member 77 may be supplied with any suitable fuel through a conduit 87 arranged in the base plate. Fixed to the upper surface of the base plate 75 are rails 89 upon which ride the wheels 90 of a truck 91. Secured to the truck 91 and projecting upwardly therefrom are bars 92 which at their upper ends support a cross bar 93. Threaded through the cross bar 93 is avertically disposed rod 94'having a hand wheel 95 secured to its upper end. Suspended from the rod 94 is a mold member 97 having a frustroconical surface 98 which conforms to the frustro-conical wall 82 of the mold member 77. The mold member 97 is rotatably secured to the rod 94, the rod being provided with a head 99 engageable by a plate 100 which is fixed to the mold member 97 by screws 101. The truck 91 may be moved from the position wherein it is shown in Fig. 7 to a position wherein the mold member 97 will be spaced in a horizontal direc tion from the

mold members

76 and 77.

Pivotally secured-to the base plate 75 is threaded therethrough. Secured to the outer end of the rod 104 is a lever 105. A head 107 swiveled upon the inner end of the rod 104 may be brou ht into pressing engagement with a reinforcing bar 108 secured to the outer surface of the mold member 76. The U-shaped member 103 may be swung into the position wherein it is shown in dotted lines in Fig. 8.

After the adhesive has been applied to the blank 25 in the manner described above, the blank is wrapped around the mold member 77, the mold member 76 being first swung out of the position wherein it is shown in Fig. 8 and the truck 91 being moved to the right end (Fig. 8) of the base plate 75. Themold member 77 is so designed that when the blank 25 is positioned thereon the

edges

32 and 33 will overlap so that the inner surface of the blank adjacent the edge 32 will engage the adhesive applied adjacent the edge 33. The blank 25 is so placed upon the mold member 77 that the seam formed by the overlapping edges of the blank will be aligned with the reinforcing bar 108 when the mold member 76 is returned to the position wherein it is shown in Fig. 8. After the mold member 76 has been returned to this posi tion the U-shaped bar 103 is returned to the position wherein it is shown in full lines in Fig. 8, in which position, it is supported by a plurality of bars 110 Secured to the base plate 7 5. The lever 105 is then manipulated to cause the head 107 to exert pressure upon the bar 108 which will, in turn, subject the seam formed by the

edges

42 and 43 to the pressure. As shown in Fig. 10, the inner surface of the mold member 76 is preferably dished or relieved, as indicated at 111, beneath the bar 108. This portion of the mold member 76 yields when pressure is applied thereto through the medium of the bar 108 so that all portions of the seam are subjected to the pressure. In practice the inner surface of the mold member 76 need only be dished or relieved a few thousandths of an inch. Of course, the mold member 76 maintains the blank 25 in its proper position upon the mold member 77 while pressure is being applied to the seam. Simultaneously with the application of pressure to the scam, the blank is subjected to heat by means of the burner 85. v v

In the next ste of the improved method, the marginal portion of the blank projecting above the mold member 77 is turned inwardly to provide a flange 113 which is indicated in dotted lines in Fig. 3. The blank 26 is then positioned upon the flange 113, adhesive being first applied to the edges 43 and 46 of this blank. This step of the improved meshod is best illustrated in Figs. 4, 9 an 11.

In Figs. 9 and 11, the blank 26 is shown with its marginal edge43 aligned with the outer edge of the flange 113, the blank 26 being held in a position wherein the edge 45 overlaps the edge 46 to form a seam. It will be readily understood that the notch 47 is provided to reduce the number of layers of material .to a minimum at one point. The blank 26 is centered by a pin or lug 83. After the blank 26 has been properly positioned with respect to the blank 25 the truck 91 is moved into the position wherein it is shown in Fig. 9 and the hand wheel 95 is manipulated to bring the frustro-conical surface 98 of the mold member 97' in pressing engagement with the upper surface of the blank 26. The blank 26 is subjected to this pressure and to the heat of the burner 85 until the adhesive sets. The article so The apparatus formed-from the

blanks

25 and 26 is then removed from the moldmembers 76'and 77 and is placed in apparatus whereby ahead is formed blank 25.

the formed blank 25' comprises a base plate 115 .upon which is mounted a holder 116 havmg a frustro conical a erture 117 conformin to the shape of the ormed blank 25 (Fig. 13 Secured to the base plate 115 and concentrically disposed in the aperture 117 is a plate 118 adapted to support the formed blank 26 when the article formed by means of the mold members 76 and .77 is placed in for forming the bead u'pon 1 formedv adjacent the largest diameter of the,

the aperture 117 in the manner illustrated in F1g. 13. As shown, the formed article will project above the holder 116 so that its upper circular edge will be disposed in alignment with arcuate grooves 120 formed in a pair of arcuate levers 121 which are ivotally secured to the base plate 115 by a bolt 122, the free end of the levers 121 being provided with handles 124 whereby the levers may be swung into and out of the positions wherein they are shown in Fig. 12. Projecting upwardly from the base plate 115 and centrally disposed with respect to the'aperture 117 is a pin 125 having a portion 126 of reduced diameter. Rotatably journaled upon the portion 126 is a bracket member 127 which carries a pin 128 pivotally securing a lever 129 to the bracket member, the longitudinal axis of the pin 128 being disposed at right angles to the longitudinal axis of the pin 125. Rotatably journaled upon the lever 129 is a wheel 130 which may be rolled around the inner surface of the formed blank 25 to expand the marginal portion 30 thereof into the annular grooves 120. This forms a bead 132. As shown in Figs. 12 and 13, a latch member 133 pivotally secured to one of the arcuate levers 121 may be employed to lock the levers in the positions wherein they are shown in Fig. 12. After the bead 132 has been formed, the levers 121 are swung out 7 of the positions wherein they are shown in Fig. 12 and the bracket member 127 together with the lever 129 and the wheel are removed from the holder 116. A metal ring 135 is then pressed into the bead 132, suitable adhesive substance being first applied to thering (Fig. 14). A rubber band 136 or the equivalent is then slipped over the bead 132 to hold it in position upon the ring until the adhesive has set.

To prevent distortion of the formed article when the bead 132 is being produced and to hold the formed article against displacement relative to the holder 116, I preferably provide a weight- 138 adapted to be inserted into the formed blank 25to hold it in engagement with the frustro-conical surface of the 'aperture 117. The weight 138 is preferably prm vided with a plurality of eyes 140 or the In Fig. 15 I have shown a tool which may be employed in connection with some of the apparatus' shown in Figs. 12 and 13 to se-- cure a metallic collarto the formed article. The late 118 is provided with a recess 142 which accommodates. a metallic collar 143, the metallic collar 143 being preferably placed in the recess 142 before the formed article is placed in the holder 116. After the bracket member 127 has been, removed from the portion 126 of thepin 125, the marginal portion adjacent the ed e 44 of the formed blank 26 is pressed into t e collar to provide an annular flange 144. An annulus or rin 145 preferably formed of paper or any other suitable fibrous material is then placed upon a cicular boss 146 formed upon a tool 147. The tool 147 is then employed to force or press the ring 145 into the annular flange 144 in the manner illustrated in Fig. 15, the tool being then removed to leave the ring 145 within the annular flan e. The boss 146 and the. ring 145 expand t e collar 143 slightly when forced into it. Then when the boss is withdrawn from the collar, the collar springs back into its normal shape and the rin 145 is compressed to secure the flange 144 tween it and the collar. The collar provides means whereby the shade may be readily mounted upon any suitable support (not shown). My copending apphcation Serial No. 43,293, filed July 13, 1925, is particularly directed to a lamp shade having a collar secured thereto as above described.
