Abstract: 222,227. Fermor, H. C. G. Ellis-. July 2, 1923. Machines for making casks &c.-Cylindrical casks of veneer, plywood, cardboard or other sheet material, arranged either in staves which may overlap or in sheets are formed by rotating hoops or like members supported in coaxial spaced relationship and feeding to the outside the material of which the wall is to be made, such material being nailed to the hoop or like members. Exterior binding hoop elements are preferably fed and nailed at the same time. To make a cask, two inner end hoops are supported on rollers d<6> and d<10> of a series of rollers d<6> - - d'o, Figs. 1, 2 and 5, which are adjustable towards and from an axis d<15> to suit casks of different sizes. These loops are further supported by anvils e<1> and e<5> of a series of anvils e<1> - - e<5>, Fig. 6. The material of the cask wall is fed by driven rollers h<2> over these rollers and anvils, the rollers d<6> &c. being rotated by their contact with the material, and the hoops and layers being secured by nails as the material passes over the anvils, the nails being driven by hand or by a suitable machine of known type. Such nailing machine may consist for example of a hopper j rocked by a rod j<3> and from which nails pass through conduits j<4> to nailing chucks k - - k<4> on each of which two lines of nails are driven by nammers m operated by springs m<2> and cam mechanism S, m<3>. In order that the rollers h<2> may be adjusted to correspond with the adjustment of the rollers d<6> to d<9>, they are mounted on arms h connected by crass-heads g<7> which are movable by rotation of shafts g<3> from a handle g<4>, links h<3> constraining the movement of the rollers h<2> into the appropriate path. A resilient contact between the rollers h<2> and the material of the cask wall is ensured by the construction of arm h shown in Fig. 7 and by mounting the part b<1> of the frame which carries the rollers movably about an axis o. Additional adjustable guide plates, rails or rollers may be provided. Simultaneous adjustment of the nailing chuchs k - - k<4> in casks of different sizes may be effected by connecting them by racks and pinions as shown in Fig. 8, so that movement of a handle k<14> only is necessary to effect the adjustment. The anvils e - - e<4> and the rollers d<6> - - d<10> may be made adjustable in a similar way. The end hoop of the cask is supported by a heading disc f<2>, Figs. 14 and 15, mounted on a bracket f. the hoop engaging rollers f<13> and an anvil f<4> adjustable to and from the centre by the rotation of an axle f<11> by means of bevel wheels f', f<8>, such adjustment causing the hub itself to move upwards towards a fixed bracket f<3> by the rotation of the uppermost of a set of screws f<7>. The head may be held on a spike f<17> on a plate f<15> held floated by springs f<16>. Additional guiding means for the material of the cask wall may be provided between the rollers h<2> and the anvils in the form of plates, rails, or rollers. Power is supplied to the various parts from a driven shaft o by the mechanism shown in Fig. 2.
