Abstract: 21,079. Thompson, W. P., [Mound City Paint and Colour Co., and Boardman, H.]. Oct. 17 Bending; glueing; wood substitutes.-Strips of thin wood, especially lumber waste, are utilized to form wood substitute, from which articles such as mosaic fabric, railroad ties, boards, water tanks, water spouts, book-cases, packages, buckets, barrels, kegs, conduits, piping and tubing of all kinds, telegraph poles, fencing and other kinds of posts, wash-tubs, boxes, &c. can be manufactured. The ends and edges of the material are chamfered or skived to lap over the ends or edges of adjacent pieces as shown in Fig. 15, in which there is a straight portion A and a bevelled part B, the skived parts being treated with adhesives and the joint compacted by pressure. In a modification, the laminations may be produced by spirally winding on a former drum alternately from opposite ends and in opposite directions continuous strips of this built-up veneer, which are chamfered on one side on their lower edges to overlap the upper chamfered edge on the other side of the next wind. One or more thicknesses of material may be used, passed together or separately over the drum, each thickness being attached to the next by adhesive and the grain of the pieces being in different directions. The prepared material is placed on a belt 4, travelling over a table 3, and is passed between a cylindrical or other former 5, a feed-roller, and compressor rollers. The former is keyed to the shaft 11, which is inserted at one end in bearings swinging on a vertical pivot and is held at the other end in a box 13 on a support 14, which is pivoted at 15 and retained normally by a groove and pivoted catch 16. At each end of the former drum are a pair of frames 20, 22, slotted to receive springs 54, Fig. 9, which press on the upper walls 55 of the slot and on blocks 56, formed with plates 57, having shoulders to catch on flanges 59. Screw bolts 60 passing through the blocks 56 are used to support the compressor rollers 23, and are adjusted by bolts 62. Adjustably connected by slots 41, 42 and bolts 43 to the front and rear frames 20 are brackets 24, which are united through a slot-andbolt connexion to arms 25, pivoted at 26 and connected by a link 28 with an arm 30, which is fixed to a shaft 31 and is provided with cams 32. The cams are used to adjust in guides 34 the feedroller 40 through a block 33, a projection on which is encircled by a spring 35 also encircling a projection from the roller bearing. The frames 22 are connected by similarly adjustable brackets 48 to vertical arms 89. The two groups of compressor rollers are held together and exert pressure on the former drum, by the pull on a bar 8 2 of hooks 80, connected to vertical arms pivoted at 90, by a bell-crank lever operated by hand or through a connecting-rod and spring-link 87 by depression of a lever. At the same time, the arms 89 force the frames 22 into contact with the former drum, the take-up being held by a dog 91 and ratchet 92. The former drum 5, which is made collapsible and is kept in shape by disks 67, 68, 69, Fig. 5, is in two parts and the cylinder is completed by a T- piece 65, Fig. 6, kept from falling outwards by pivoted buttons 66 and being disengaged by having at one end of its web a bevel and at the other a bevel notch. The shaft 72 is operated by a crank 73 and actuates the half-sections 63, 64 to move on hinges composed of straps 74, pivoted to the disks 67, 69 by bolts 75 passing through enlarged openings in the end plates 77. The machine is operated by power cr by a lever arm 93, a spring- pressed trigger to prevent recoil of the former being drawn out of engagement with a ratchet wheel by. a pivoted hand-grasp.
