My invention relatesto the class of machines used for felting hat-bodies, which is usually done after the hardening7 of the bodies; and it consists in improved means for moving the swinging frame and determining its play; in

details of the construction of the rollers; inthe adjustable weight and means for moving and holding it; in the rollercove,rs; in thcjournal boxes and bearings; in the stopping mechanism that dctermines the amount of rolling a given roll of hatbodics shall receive; in the counting mechanism that forms part of the stop mechanism, and in details of the construction and combination of the several parts, as more particularlyhereinafter described and claimed.

In the accompanying drawings,the letter A denotes the main or stationary frame of the machine; A', the table, fast to and projecting from the front of the frame, and on which the hat-bodies are prepared for the machine felting; B, the tank, secured to the frame from side to side below the rollers, for holding hot water or other suitable liquid for use in felting; C, the swinging frame, pivoted to the horizontal shaft C, that is supported in bearings in the upper part of the rear of the frame A; D, the top roller, fast on the shaft d', that is journaled in bearings across the front of the swinging frame parallel to and over the lower rollers, E and E. Y

rIhc treadle F is pivoted to the lower part of the frame with a foot-board, f, extending from side to side below the table. The inner ends of the side levers, j", of the treadle are united by the rods f to the swinging frame C, the parts being so arranged that by pushing down upon the foot-board f the frame C will be raised and the roller D lifted away from the lower rollers. The lowerlimit ofthe swinging play of the upper roller, D, is determined by means of the brace r/. that in the form shown in Fig. 2 is composed ofthe tubular part g', pivoted to the cross-bar on the treadle-frame and extending upward, the rod g, pivoted to the lower side of the table A and extending into the tube g. The upper and, threaded part, y, of the rod bears a nut, g4, with a hand-wheel, g, and the lower surface of this nut rests against the upper end of the tube g. NVhen the treadle is pushed downward, the tube gf slides freely on the rod g2, and as soon as the pressure is removed the treadle rises again until the upper end of the tube strikes the lower end of the nut.

In addition to the weight of the swinging frame C and the roller D, an arm, cl, fast to IOO the frame and projecting from it over the roller D bears the sliding weight c3. This weight is held upon the armby a dovet-ailed groove in its lower face, and has a vertical socket, in which is a loose block, c, and this socket is traversed horizontally by the shaft c?, that bears a handle, es, in convenient position within the reach of the operator. The inner end of this shaft is threaded and takes into a threaded socket in the weight, and it bears a cam, c", directly over the block c, so that by the rotation of the shaft the block may be clamped upon the arm c?. The pressure upon the roller D may be adjusted by sliding this weight c3 to any position along the arm c?.

The rollers D, E, and E are borne on shafts that turn in peculiar bearings in the supporting.- frame, and they may be of any desired shape as to periphery. Each roller is preferably made up .of two semi-cylindrical pieces of wood, 4grooved out along the center of their flat surfaces and held upon the shaft with these faces in contact by means of a cast metal cap, h, having inward-projecting flanges h', that take into transverse grooves h3 across the ends of these wooden roller-sections. This method of clamping the roller-sections together prevents them from becoming loose and turning on the shaft. The working-surface of the rollers may be corrugated or iluted either by cutting awaythe substance of the wood or by nailing on lagging or by being covered .with

, the corrugated face-plates h* in the forlnsshown in Figs. 14 to 17. Y

Each of the shafts or journals of the main rollers turns at each end in an improved box or bearing, I, that is self-adjusting. In this bearing (see Figs. 1-0 and 1l) the frame or hanger branches or forks, and has on the inner face of one of the branches ashallow socket that is dished or shaped like a segment of a sphere, and in this a correspondingly-curved surface, 2, of the box ilits and moves. In the other branch of the frame and opposite this socket is a mortise, 113, in which a block, it, is so fitted as to be movable to and from the box. Its under surface is hollowed and ts upon the rounded surface i5 on the box.

I n the mortise and back of the block i* is a plug, i6, that extends through the end wall of the mortise, and bears a iiange within it that lprevents it from passing through this wall.

A bolt, il, passes centrally through a threaded socket in the plug, takes against the back of the block, and bears a jam-nut, by means of `which it is held firmly when the requisite grasp upon the bearing that will yet allow of its swinging to conform to the alignment of the shaft has been obtained.

The shafts bearing the several rollers in this machine are driven by belts from a countershaftand by belts orint-ermeshing gear-wheels, so that the rollers turn in one direction (denoted by the overlying arrows) and a roll of hat-bodies placed between the vrollers will be subjected to a felting operation.

After the process termed hardening the hat-bodies are still of such delicate texture and the fibers of fur so slightly knitted togetherthat great care in handlingis required. A sufficient number of such bodies is rolled up in a cloth, and this roll is placed between the rollers of the machine, and,in order to prebodies from becoming felted together, they have to be opened out and folded in a different place after a limited amount of rolling. The result of such a felting together of the sides of a body is a streak that ruins it, and such an occurrence is prevented in my machine by the stop mechanism.

The stop mechanism-*The shaft e2 of the roller E extends beyond the side of the frame of themachine, (see Figs. l and 2,) and bears a loose pulley, c3, that is held against endwise play by a collar or nut fast to the outer end of the shaft, and the body e* of the clutch e5 4 fast to the same shaft on the opposite side of the pulley-hub. Between these latter parts the shaft bears a rotary disk, e, with an eX- tended arm or dog, el, that projects between the arms of the pulley, and it is held against the 'arm e by the spring e9, that breaks the shock of the engaging action of this form of clutch, which is positive. The sleeve el0 is fitted outside of the body part e of the clutch, and has a sliding motion on it, bearing the bolts c12 by means of pins cl3. (See Fig. l.) The bolts move in sockets in the clutch-body and are projected through openings in i ts front wall by the springs en. When these bolts engage in sockets in the dog,the shaft et is turned with the pulley and the parts are disengaged by the inner end of the lever lc', that, under certain conditions hereinafter'described, is so lifted against a cam on the sleeve by the spring el5 ais to slide it endwise away from the hub, so as to withdraw the pins and release the pulley. The lever 7c is pivoted in a vertical position to the frame near the clutch, is pushed toward it by the spring 7a4, and it bears a roller inthe path' of the cam el, that is formed on the face of the clutch-body, and the lever 7c is pivotaliy suspended from its lower end. The latter hangs in a horizontal position with the arm k2, Aextending under the clutch-body, and the arm lf3, curved over the ratchet-wheel l in theopposite direction and adapted to engage the teeth of the wheel. This ratchet-wheel Z and a gear-wheel, l', placed next to it, both 'turn freely on the short shaft that projects from the frame of the machine, but interlocking parts on each wheel limit their relative rotation. The ratchet-wheel is turned toward the pawl by means of a weight suspended from a cord wound about a part of the wheel, (see Fig. 2,) and a segment, l2, of the wheel is cut aw-ay, so thatthe lever on the presentation of this part will drop inward toward the axis of the wheel. The lever k is swung forl vent the opposite sides of any one of the hatl Y IOO IFS

ward as the cam on the clutch-body strikes it v in each rotation of the main shaft, and it causes the pawl to turn the ratchet-wheel over a distance equal to one tooth, and as soon as the cam has passed, the lever and the pawl are forced back by the spring kt, the lever swinging clear of the ratchet-wheel, while the arm 7c3 of the lever, which rests on the wider part of the face ofthe ratchet-wheel, prevents the latter from turning back. This operation is repeated at each rotation of the main shaft until all of the wider part of the face of the ratchet-wheel (which part ends at Zi) has been carried past the end of the arm ks. vVhen this point is reached, the spring forces up the end l. of the lever and unlocks the clutch. The sliding` rack mis borne in supports on the frame, and itsteeth are in mesh with those of the gear-wheel Z', in such position with relation to the engaging-lugs on the gear-wheel and ratchet-wheel that the scale m on the side of the rack in connection with an index will indicate the number of teeth the lever will engage before it drops off the wheel and operates the clutch to release the driving-puh ley as described. As soon as this pulley is released the rollers stop turning, and, by means of the treadle, the swinging frame and upper roller are lifted so that the roll of hat-bodies may be removed and refolded or another roll inserted. rlhe rod f2 bears the lifter oathat is adjustable along the rod, and a lug, L5, projects from the side of the arm k in the path of the upper end of this lifter, so that it is struck by it as the rod is raised in lifting the swinging frame. The pawl is thus tilted and the ratchet-wheel returned toits starting position by the weight and cord.

In Figs. 14 and l5 the ratchet-wheel is shown,

on an enlargedseale in side and edge view. The wider part of the edge denoted by l, on which the end of the arm k rests, does not extend so far as that part of the ratchet marked 2, upon which the operatingpawl K works, while the upper part of the section 2 is cut away to the point The result is that when the device is set to make the maximum number of revolutions given on the rack, the operating-pawl I( strikes on the rst tooth beyond the said depression; butif the rack is set farther out than the maximum number, the operating-pawl will strike idly on the section ot' t-he ratehetwheel where there are no teeth and the motion of the rollers will be continuons.

An alternate device for stopping the rollers of the machine is illustrated in Figs. 18, 19, and 20, and in this latter form I use a fast and loose pulley and a beltshifter, o, that is operated by the movement of the lever 7a. This belt-shifting device is substituted for the clutch, which is not used in this form. The other parts and their operation are substantially the same as in the form already described.V In the latter form the bent lever o is pivoted to the frame ofthe machine with the shorter arm, o2, slotted to receive aprojeeting pin on the outer e'nd of the lever k', and the longer arm extending upward and slotted to receive a pin projecting from the sliding shifter-rod o3. This latter is supported in a socket in a bracket fast to the frame of the machine, and bears the ordinary pins, o", adapted to engage the opposite sides of the belt. lhe sprlng of, seated in a recess in the shifter-rod, is arranged to hold the latter, so that the belt will be thrown over onto the loose pulley as soon as the level| It" is freed from the ratchet and its outer end lowered.

An equivalent means of preventing the rollers from acting on a roll of hat-bodies is shown in Figs. 21. and 22, and the object ot' this device is to slide one of the lower rolls away from the others at the end of a predetermined number of revolutions, and thus let the roll of hat-bodies drop between the rollers. The clutch is not used in this latter form, but the ratchet-wheel, pawls, and counting meehanism remain substantially the same. rIlle bearingp of one of the lower rollers (as the front) is supported on aslide that moves horizontally on the frame, and this bearing isheld with the roller in position to operate on the hat-bodies by the hook on the upper side of the lever c',that engages a lng on the bearingblock. This block is also connected to the rod j by the lever 1- and toggle r', the lever being pivoted to the frame ofthe machine and connected to the block by a pin on the latter, that takes into a slot, r2, in the upper end of the lever. The spring r is connected to the frame and to the lower end of the lever r in such position that as soon as the dropping of the lever 7n' releases the bearingblock it is slid outward by the lever and spring. This movement of the block separates the rollers and allows the roll ot' hat-bodies to drop through onto ashelf or into a receptacle. The block and roller are returned by an upward movement of the rod, as before. This automatic separation of the rollers may evidently be accomplished by swinging instead of sliding the roller, and it is not material whether one or both of the rollers are moved so long as a sufficient open ing between their peripheries is made for the passage of the roll of hat-bodies.
