MACHINE FOR FORMING VENEER DRUMS.

SPECIFICATION forming part of Letters Patent No. 360,344, dated March 29, 1887.

Application filed September 16, 1886. Serial X0. $3,654. (No model.)

To all whom it may concern:

Be it known that we, WILsoN GODFREY and GEORGE \V. HALSTEAD, both of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Forming Veneer Drums, of whichthe following is a full, clear, and exact description.

The object of our invention is to facilitate the manufacture of the so called veneer drums, which are subsequently provided with heads to form packages used principally for various kinds of dry groceries.

These drums are usually made threeply of three sheets of veneer glued together, the grain of the central sheet crossing the grain of the two other sheets, so the drum will not split or crack; and our process is first to glue the three sheets of veneer together and then turn them over a former and unite the edges;

. and in our process we compress the sheets of veneer upon the former while the glue is moist, and thus cause the sheets to be perfectl y united in the act or operation of bending them to cylindrical form, so that when the glue sets and becomes dry the sheets will not cleave apart at any portion of the drum, and the machine is constructed to enable the lapped edges of the sheets, when turned to form a cylinder, to be clamped firmly by a suitable clamping device, and then withdrawn from the iblllllng-Cylillder, ready to receive the heads and hoops to complete the package.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. Figure 1 is a plan view of the forming-cylinder, showing the passage formed therein to receive the clamping device, a part of the oylinder being broken away to show the flange at the ends, and this figure shows also a part of the table at the end or edge of which theformingcylinder is held. Fig. 2 is an end view of the same, showing the sheets of veneer placed upon the table and one edge attached to the forming-cylinder, and the latter given a one'quarter turn from the position shown in Fig. 1. Fig. 3 is a similar view showing a clamp applied to the cylinder for holding the veneer firmly thereon.

Fig. 4. is alsoasimilar view showing the weighted arm or compressing device for compressing the sheets ot'veneer upon the formingcylinder. Fig. 5 is an end elevation showingthe forming-cylinderturned to lap the edges of the veneer and two clamps applied for holding the veneer, the compressing device being shown upon the veneer in full lines and elevated in dotted lines. Fig. 6 is a. broken end elevation showingthe clamping device applied to the lapped edges or joint of the drum, ready to remove the same from the forl'ning-cylinder. Fig. 7 is an end View of the veneer drum with clamping-bars attached and removed from the forming-cylinder, and provided with a false head inserted in the drum to prevent warping. Fig. 8 is a longitudinal sectional elevation of the drum and clamping device removed from the forming-cylinder. Fig. 9 is a sectional front elevation of the forming-cylinder, showing the clampingbar L secured upon the veneer and to the end flanges, a, of the said forming-cylinder.

A represents the formingcylinder. This is formed at its ends with the flanges a, and has the longitudinal passage A formed in it, and is secured upon the crank-shaft B, which is journaled in bearings formed in and upon the supports B B, adjacent to the table 0. The longitudinal passage A in the forming-cylinder is made dovetailed to receive the clamp ing-bar D, and to hold it when shoved endwise into said passage against any material outward movement away from the axis of the cylinder.

In the recess A is pivoted the frame E, for holding the ends of the sheets F of veneer at the outset of forming the drum. The frame E consists ofthe two side pieces, 6 e, pivoted to the ends of the cylinder A and the cross rod e, secured in the outer ends of the side pieces, 6 e. The side pieces, 0 c, are hinged at the bottom of the recess A,and are of such length as to hold the bar e slightly beyond the circle or curve described by the periphery of the forming-cylinder, so that the ends of the veneer may be placed under it, as shown in the drawings. A slot, 0, is formed in the bottom of the recess A, to receive the rod e, so that the whole frame E may be turned down below the bottom of the passage A, as shown in Figs. 2

and 3, so that said frameiwill not interfere with the clan1ping-bar D"when shoved endwise into the recess A.

The clamping-bar D is made to fit the recess A with beveled side edges, and is slightly rounded at its outer surface to correspond with the radius of the cylinder A, and is formed with a notch, a, at each end to retain the headed bolts (1, passed through the outer clamping-bar, D. (Shown in Figs. 6, 7, and 8.) The outer clamping-bar, D, is provided with the screw cl, and when united to the barD by the bolts d d an intermediate bar, D, is placed between the bars D D upon the ends of the veneer F, so that when the screw (1 is turned down the said bars D D will clamp tightly upon the ends of the veneer.

G represents the device or arm for pressing the sheets of veneer upon each other and upon the forming-cylinder A, so that they will be glued together at all points, and will accurately take the form of the cylinder as the same is slowly turned by the crank B. The arm G is hinged at g to a suitable support, H, so that it may be raised by a rope andpulleys, J J, or other means, to a position above the forming-cylinder, as shown in dotted lines in Fig. 5, or lowered to rest upon the formingcylinder, as shownin full lines in Figs. 4 and 5. The arm G is of considerable weight, and it is provided with the heavy roller G, which runs uponflthe veneer, and a brake, G", is arranged to be pressed by screws K, against the roller G, so'that the friction of the roller G upon the veneer may be regulated, and so that the roller may be made to wholly slide upon the veneer, if desired.

In forming a three-ply drum three sheets of veneer are coated properly with glue, and placed together upon the table 0 with the edge of the middle sheet drawn back a short distance from the edge of the bottom sheet, and the edge of the outer sheet drawn back from the middle sheet, and the edges adjacent to the cylinder A are placed under the cross-bar c of the frame E, the said frame having been previously turned to radial po sition, as shown in Figs. 2, 3, and 4. The cylinder A will then be turned by the crank B ashort distance to curve somewhat the edges of the'sheets of veneer, as shown in Fig. 2. Then a clamp, L, is applied to the veneer and drum, the same being held by hook-screwslat the ends of the clamp engaging with the flanges a at the ends of the cylinder. This clamp L being applied, the arm G is lowered upon the veneer, as shown in Fig. 4. Then the cylinder A is turned by crank B nearly a complete revolution, which causes the veneer to be wrapped completely around the cylinder and the sheets to be compressed snugly together. At this time one edge of the sheets of veneer will be held by the clamp L, while the other edge will be held by the weight of the compressing device G. Then another clamp, L, is applied to 'the cylinder and veneer, the same being held by hooked bolts Z, applied to the flanges a, of the cylinder, as shown in Fig. 5. The two clamps L L being thus applied to hold the edges of the veneer to the cylinder A, the arm G will be raised off from the veneerand the frame E turned down into the recess 0, as shown in dotted lines in Figs. 5 and 6, and then the clampbar D will be shoved endwise into the recess A. The opposite edges of the several sheets of veneer will then be properly lapped upon each other to form the joint, and then the clamp-bars D D will be applied and the screw d turned down to firmly secure the lapped edges of the veneer,aii d then,finally,the clamps L Lwill be removed, and the drum and clamps D D D" drawn off together from the formingcylinder for further treatment (to receive the heads, hoops, &c.,) to form the drum into a complete package. In this mannerthe drums may be very expeditiously made and the joint easily formed and secured, and the sheets of.

veneer being compressed make the package very strong and durable.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The forming-cylinder A, formed with a recess, A,and provided with a retaining-frame, E, composed of side pieces and a cross-piece, the side pieces being hinged at the bottom of the recess, in combination with the clamping bar D, substantially as described.

2. The forming-cylinder A, formed with the recess A, in combination with the bar D and the outer bars, D .D bolts (7, and screw (1', substantially as described.

3. The cylindrical former A and devices for clamping and holding the veneer thereto, in combination with the compressing device G, hinged to a suitable support and provided with a roller, G, and brake G arranged to be ap plied to the roller, substantially as and forthe purposes described.
