MACHINE FOR RCUNDING HAT-BODIES.

SPECIFICATION forming part of Letters Patent No. 557,896, dated April '7, 1896.

Application filed August Z, 1895- To all 10700720 it 777/[LZ/ concern.-

Be it known that I, AUGUSTUS C. SAXTON, a citizen of the United States, residing at Bethel, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Rounding Hat-Bodies; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to produce a machine for rounding hat-bodies which shall be simple and inexpensive to build, will insure a perfectly neat and uniform quality of work, and which shall, moreover, have a capacity greatly in excess of any other machine heretofore built for this class of work. )Vith these ends in view I have devised the novel machine of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to designate the several parts.

Figure 1 is a plan view of the machine complete; Fig. 2, an elevation thereof; Fig. 3, an end view, the cone being removed; and Fig. i is a detail sectional view of the cutter and upper feed-roller.

1 denotes the frame of the machine, which may be of ordinary or any preferred construction.

2 denotes a shaftsuitably journaled in the frame, to which power is applied by a belt (not shown) running over a belt-pulley 3. At the inner end of this shaft is a roller 4, which Iterm the lower feed-roller and which also serves as the lower cutting-roller.

5 denotes a shaft one end of which is jour naled in the frame in such a manner as to rocki. 8., to permit a slight upward and downward movement of the opposite end of the shaft for the purpose of adjustment, (see dotted lines, Fig. 2,) said opposite end being journaled in a sleeve 6, having a threaded shank 7, which is adjustably secured in the framework by upper and lower adjusting nuts 8. Near the inner end of shaft 5 is a cutter 9, the edge of which laps past the edge of roller 4, on the inner side, as clearly shown in Fig. 3.

10 denotes the upper feed-roller, which is provided with a central opening 11, through Serial No. 560,432. (No model.)

which the shaft passes loosely, the inner face of the roller lying in contact with the face of the cutter, as clearly shown in Fig. 4. The outer end of the shaft is threaded and the cutter is turned up tight against a shoulder 12. Roller 10 is held in position by a washer 13, against which a spring 14 bears, the tension of said spring being adjustable by means of a socket-nut l5,which engages the threaded end of the shaft and receives and holds the spring securely. (See Fig. 4.) The cutter is held closely in contact with roller 4 by means of a spring 16, one end of which presses against a collar 17 on shaft 5, the other end bearing against the framework, the action of said spring being to force the shaft toward the left. Motion is communicated from one shaft to the other by means of a gear-wheel 18 on shaft 2, which engages a corresponding gear-wheel 19 on shaft 5.

The hat-body to be operated upon is carried by a cone 20, having a short shaft 21, which engages a socket 22 in a carriage 23. The cone is preferably journaled at such an angle to the frame as to place the upper side thereof in line with the engaging surfaces of the feed-rollers, as is clearly shown in Fig. 2. The carriage is adjusted in or out relatively to the cutter to regulate the length of the rounded bodies by means of pinion 24, (see dotted lines, Fig. 2,) which engages a rack 25 on the carriage, and whose shaft 26 is provided with a hand-wheel 27 for convenience in operation. This hand-wheel is provided on its face with a scale 28, which corresponds with a scale 29 on a plate 30, which is secured to the carriage and moves in a guide 31 on the frame. The hand-wheel is locked in position at suitable adjustmentsfor instance, at adjustments of one-fourth of an inch-by means of a spring-bolt 32, which is socketed in an extension from the frame and is adapted to engage recess 33 in the hand-wheel. (See dotted lines, Fig. 2, also Fig. 3.) It will be seen that the adjustment is very convenient and practically instantaneous in changing from one length of hat-body to another, either of the scales showing at all times to just what length the bodies are being rounded or trimmed.

It will of course be understood that the special design of the framework and of the carriage is not of the essence of my invention. I preferably, however, design and organize the machine substantially as shown in the drawings. It is of course necessary that the carriage be provided with a rack orits equivalent and that the parts be so constructed that the carriage will move easily in the framework, but without lost motion. I therefore form the rack upon a bar 34, which slides in a corresponding socket in the frame, and also support the carriage at the top by means of a plate 30 and guide 31.

The reason my present machine will do better work and more work than other machines heretofore used for this purpose is owing to the fact that the feed is such that the work is self-holding-that is to say, the hatbodies are acted upon by the feed-rollers in such a manner that they are drawn toward the cutter until after the cut is made, all tendency of the hat-body to run out being avoided, and instead of a tendency to run out the hat-body is drawn inward toward the cutter. In order to accomplish this result, I journal the cone obliquely to the vertical plane of the machine and inclining in the direction from which the hat-body is fed, (see Figs. 1 and 3,) and also journal said cone obliquely to the horizontal plane of the machine-that is, oblique to the central line of the machine,as viewedin the horizontal plane, and inclining upward. (See Fig. 2.) The effect of this arrangement of the cone relatively to the cutters will be clearly understood from Fig. 1. It will be apparent that just as soon as the edge of the hat-body is placed between the feed-rollers the action of said rollers will be to draw the edge of the hat-body inward toward the cutter, which action continues until after the edge has passed the point at which the cutting action takes place.

The feeding action is as follows: It will be noticed (see Figs. 3 and 4) that the feed-rollers and the cutter are of equal diameter, and, furthermore, that the distance between the centers of the shafts is less than the diameters of either of said rollers or the cutter. It will also be noticed that the cutter laps past the lower feed-roller and that the upper feedroller, which is in peripheral engagement with the lower feed-roller, is provided with an enlarged central opening, through which the shaft passes loosely. The result of this construction is that in use the upper feed-roller is carried forward by the lower rolleras far as the central opening will permit, (see Fig. 3,) so that the hold of the rollers upon the hatbody is forward of the point at which the cutting action takes place. This insures a perfectly-even feed and renders it impossible for the hat-body to buckle or double in the machine.

Having thus described my invention, I claim 1. In a machine of the character described, the combination with suitable feed-rollers and a cutter, of a carriage, and a cone journaled in the frame obliquely.

2. I11 a machine for rounding hat-bodies the combination with suitable feed-rollers and a cutter, of a cone journaled in the frame obliquely to the vertical plane of the machine and inclining in the direct-ion from which the hat-body is fed, and obliquely to the horizontal plane of the machine and inclining upward so that in use the hat-body is drawn toward the cutter, and tendency to run out is avoided.

In a machine of the character described the combination with a cone journaled in the frame obliquely both to the vertical and the horizontal planes of the machine, of shaft 2 carrying the lower feed-roller 4, shaft 5 carrying a cutter which laps past the edge of feedroller it, upper feed-roller 10 having a central opening through which shaft 5 passes loosely,

a washer, spring and socket-nut by which the disk is held in operative position and suitable means for imparting rotation to said shafts as and for the purpose set forth.

4:. In a machine of the character described, the combination with the cone, of shaft 2 carrying lower feed-roller 1, and shaft 5 carrying upper feed-roller 10 and cutter 9, one end of said shaft being journaled in the frame and adapted to rock in the vertical plane, and the other end being j ournaled in a sleeve having a threaded shank 6 which passes loosely through the frame and is adjustable by means of nuts 8 engaging the opposite sides of ,the frame.

5. In a machine of the character described, the combination with the cone, of shaft 2 carrying lower feed-roller 4:, shaft 5 carrying a cutter the face of which is adapted to bear against the side of feed-rollei land an adj ustable collar 17, upper feed-roller 10 having a central opening through which shaft 5 passes loosely, suitable means for retaining the upper feed-roller in position and a spring 16 one end of which bears against the frame the other against collar 17 whereby the cutter is retained in operative position.

6. The combination with feed-rollers and a cutter, of a suitable frame, a carriage-having a rack and a socket 22, a cone having a shank adapted to engage the socket, shaft 26 carrying a pinion engaging the rack and a handwheel 27 having a scale on its face to deter mine the adjustment of the cone relative to the cutter, and recesses 33, and a spring-bolt to engage the recesses to lock the carriage at any adjustment.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUSTUS G. SAXTON.
