As soon as the pin 0 comes oppobelt-pulley e transmits power through a belt site its recess in the frame it will move longitudinally out of engagement with that one of the pins e with which it was previously engaged. Hence it will no longer be in condition to derive motion from the driving-belt pulley 6 and will, moreover, be stopped by engagement with the frame A.

E is a lever fulcrumed to the cross-piece or bed a of the machine-frame. At one end it is bent to extend into the recess which is provided in the machine-frame for the reception of the pin c". This end is moved outwardly away from the recess by aspring e as far as it is permitted to move by a stop-pin 6 which is inserted in the cross-piece or bed a. The other end of thislever is provided with a handle and extends into a position convenient for the operator of the machine. \V hen this lever is oscillated against the resistance of the spring 6, it may be made to force the pin 0 out of its recess in the machine-frame A and into the path of one of the pins 6.

The advantage of providing a number of pins 0 is so that the driving-pulley e may more readily engage with the bevel gearwheel a. Ayielding connection between the pins 6 and the driving-belt pulley c is advantageous, because if the lever E should force the pin 0 toward the driving-belt pulley (2 when one of the pins e happens to be opposite said pin 0 breakage will be obviated by the longitudinal yielding of the pin c and after that the next pin e will engage with the pin a. J designates a hold-down having a bodypiece which has a swiveling connection with a vertically-movable slide K, and having combined with it outwardly-movable arms, which coact with the segmental pieces of the hat holder. The slide K can be depressed by a treadle L, connected with a lever G by means of a cord g, passing around guide-pulleys g 9 g g". The lever G is slotted at the free end to connect with a pin projecting from the slide K. A counter-balance may be combined with the slide K. When a hat is put in a holder, the hold-down is depressed by means of the treadle to secure it therein.

D D designate cutters, which are employed to trim the hatbrim. They are shown as supported in a frame D, which is aflixed to a slide D, that is fitted to a slide D, so as to be adjustable toward and from the center of the hat-holder. The slide D is in turn fitted to a slide D, so as to be adjustable relatively thereto toward and from the center of the hatholder. Ascrew (Z clamps the slides D D together, and a screw d serves to clamp the slides D" D together.

The cutters are shown as mounted upon rotary shafts, the upper of which is normally elevated by springs d from the other, but is, when the cutters are to operate, depressed by a lever D which is swung downward by the lever G, and in its descent causes a gearwheel d affixed to the shaft of the cutter D to engage with a gear-wheel d, with which the shaft of the lower cutter D is provided. The upper cutter will then derive rotary movement from the shaft of the lower cutter.

The shaft of the lower cutter is driven by a belt (Z from the shaft F, which is journaled in the machine-frame.

The slide D has a horizontally-extending portion and a downwardly-extending portion. The horizontally -extending portion is provided on the under side with rollers (Z which are fitted to studs extending from lugs formed with the slide, and travel along rails or shoulders (Z with which the machine-frame is provided. The do Wnwardly-extending portion of the slide D is preferably provided with a roller d which bears against a cam H. This cam may advantageously be made of wood. It is mounted upon a shaft I, which is arranged in line with the shaft 0 and derives rotary motion from the latter.

The cam II is to have the same outlinc'as that to which the brims of hat-bodies are to be trimmed, although it need not be of the same size as the edge of the brims when trimmed. As this cam rotates it moves the slide D, and consequently the slides D D and cutter-carrying frame D, relatively to the center of the hat-holder. As shown, it only moves these parts outwardly, and a spring D which, as here shown, acts against the slide D moves them inwardly. This spring, as shown, at one end surrounds a pin that projects outwardly from the horizontal portion of the slide D and extends into a pocket (1 with which the machine-frame is provided. The spring bears against a plate, which is attached toa screw (Z that is longitudinally adjustable in the pocket. Hence by manipulating this screw the tension of the spring may be varied. The pocket, as here shown, is made integral with a bracket which is fastened to the machine-frame.

Obviously different hat-bodies will require cams H of different shape, and owing to this I provide for readily substituting one such cam for another. A simple way of affording this provision consists in constructing the upper end of the shaft I to interlock with the lower end of the shaft 0 and so supporting the shaft I that it may be moved vertically to disengage it from and re-engage it with the shaft 0. The shaft I has its upper end made polygonal, and the shaft 0 is provided with a socket capable of engaging with the polygonal end of the shaft 1. This socket is not in the present instance formed in the shaft 0, but consists of a collar 0, which is attached to the shaft 0. This collar is shown as fastened to the shaft 0 indirectly by being secured through the agency of screws to the gearwheel 0, which is secured to the said shaft.

The shaft I is supported in a bearing 1', which is provided in a cross-piece of the machine-frame, and at the lower extremity has a step bearing in a sleeve 1 that is pivotally connected by a pin twitha lever I This lever I is fulcrumed by a pin 7; to a bracket t secured to a cross-piece of the machineframe. Between the ends it is slitted or bifurcated to embrace the sleeve 1 and this portion is connected by the pin i to said sleeve. The other end of the lever I has a handle, whereby it may be swung up and down to raise and lower the shaft I. This end of the lever may, by a slight lateral movement, be engaged with and disengaged from a hook a, which is fastened to the machine frame. When the lever is engaged with this hook, it will support the shaftI in a position to maintain engagement with the shaft 0. After the disengagement of the lever from the hook the lever may be lowered to disengage the shaft I from the shaft 0. After this the cam H may be lifted off the polygonal end of the shaft I with which it interlocks, and it may be replaced by a different cam, after which the shaft I will be elevated again to engage with the shaft 0.

M designates a chalk holder. As here shown, it consists of a lever fulcrumed by a pin on to a stationary partof the machineframe and having a socket on, which holds a piece of chalk. By oscillating the lever the chalk may be brought in contact with the under side of the brim of a hat-body. The socket for the chalk has preferably combined with it a screw m which may serve to cause the chalk to project more or less. Normally the lever of the chalk-holder rests upon a stop-pin m The socket m of the chalk-holder is shown as formed with a plate m which has a sliding connection with the lever M. In this way the chalk may be adjusted to act on the brim nearer to or farther from the crown. If the cross-pin m were elevated a little, so as to move the lever M into a horizontal position, the sliding section m could be moved lengthwiseto mark upon the lower end of the under side of the brim without any operation of the lever M. In this case the lever would have to be shortened at the end which is the nearer to the hat-holder, so as to allow of the adj ustment of the chalk beyond the circumference of the brim.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-
