IMPROVEMENTINMACHINES FOR FORMING HAT-FRAMES.

Specification formingpari of Letters Patent No. 143,814, dated October 21, 1873; application filed V a April 12, 1 73.

To all whom it may concern Be. it known that we, BIAGIO ERTOLA and ANGELO OAsELLI, of the city, county, and State of New York, have invented a new and useful Improvement in Machine'for Forming Hat-Frames, of which the following is a specification:

Figure 1, Sheet 1, is a vertical section of our improved machine. Fig. 2, Sheet 1, is a front view of the same, partly in section, to show the construction. Fig. 3, Sheet 2, is a top view of the same.

Similar letters of reference indicate corre-' Our invention has for its object to furnish an improved machine for forming hat-bodies, which shall be simple in construction, effective in operation, and convenient in use, enabling the work to be done with a less number of workmen than is possible when the ordinary devices are used. The invention consists in the spirally-grooved vertical shaft, the pin, the foot-lever, and the spring, in combination with the circular table, for receiving and rotating the lower form or mold; in the combination of the upper circular table, the short shaft, the

top cross-bar, the rods, the lower cross-bar, the

. with the frame-work of a machine for forming hat-frames; and in the combination of a pivoted knife with the operating parts of a machine for' forming hat-frames, as hereinafter fully described.

A represents the frame-work of the machine. 13 is a vertical shaft, the lower end of which is pivoted to a cross-bar of the frame A, and its upper end revolves in bearings in the table Q of the machine. The middle part of the shaft B has a spiral groove or slot formed in it to receive a pin, 1), connected with the lever E, the inner end of which is pivoted to a crossbar of the frame A, and its outer end projects so that it may be conveniently operated by the workman with his foot to revolve'the shaft 13.

The lever E is raised, turning the shaft B back to its former position, by a spring, F, one end radial slots formed in it to receive the bolts by which the lower formor mold H is secured to said table. I is the upper form or mold, which is secured to the circular table J bybolts, said bolts passing through radial slots formed in the said table J. The table J is rigidly attached to a short shaft, K, which passes up through a hole in the cross-bar L, and has a groove formed around its upper end to receive a hook or latch, 71, pivoted to the cross-bar L, so that the said form I may be raised by and with said cross-bar L. To the ends of the cross-bar L are attached the upper ends of two rods, M, which pass down vertically through holes in the side parts of the frame A, and their lower ends are attached to the ends of the cross-bar N. The cross-bar N has a hole formed through its center, through which the shaft B passes. The cross-bar N is connected with the foot-lever O by a hook, P, or other convenient means, so that the operator can bring the upper mold I down upon the lower mold H to form the hat by pressing down the lever O with his foot. The upper mold I is raised by the action of the springs Q, the lower ends of which are attached to a cross-bar of the frame A, and their upper ends are attached to the rear ends of the levers It. The levers It are attached to a cross-bar, S, the ends of which are pivoted to the side parts of the frame A. The forward ends of the levers R are connected with the cross -bar N by hooks T, or other convenient means. U is the material from which the hatframes are formed, and which is wound upon a rod or shaft, V, which is passed through holes in the rear ends of the arms W rigidly attached to the lower rear part of the frame A. X is a frame, the lower ends of the side bars of which are pivoted to the arms \V. In a socket in the upper part of the frame X is placed a water-vessel, Y, with the discharge-opening, in the bottom of which is connected a pipe, Z, having a number of small op enin gs formed in its lower part, through which the water from the vessel. Y escapes to the sponges A in sufficient quantity to keep said sponges so wet as to dampen the material U sufliciently. The sponges A are placed upon a wire or rod, B, which is passed through holes in the side bars of the frame X in such a position that the sponges A may dampen the material sufliciently as it is unwound from the rod or shaft V. The material U passes up along the rear side of the frame A, and between. two rubber rollers, O, by the action of which the material is made of uniform dampness. The upper roller is held down upon the material with. any desired pressure by set-screws l), which pass through the top of the part of the frame A, in which the bearings of said rollers 0 work. The forward ends of the set-screw- D rest against the half-bearings of the upper roller 0. E isa knife, having an edge upon each side, and the shank F of which is pivoted to the upper end of the shaft B, just below the circular table G, so that when the desired amount of material has been drawn through the rollers G the knife E may be swung around in one or the other direction to cut it off, so that it may be properly manipulated while upon the forms or molds. The knife E is attached to its shank l3" adjustably, so that it may be moved out or in, as a larger or smaller piece of the material is to be cut off.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The grooved -or slotted vertical shaft 13, D pin D, foot-lever E, and spring F, in combina-- tion with the circular table G for folding and rotating the lower form or mold H, substantially as herein shown and. described.

2, The combination of the circular table J, short shaft K, cross-bar L, rods M, cross-bar N, foot-lever O, springs Q, and levers R, with the table Gr, grooved or slotted shaft B, pin D, foot-lever E, and spring F, for applying the pressure while allowing the molds or forms to be rotated together, substantially as herein Witnesses;
