others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide a simple and inexpensive automatic machine for wetting hat bodies while on the cone.

It is well understood by those familiar with the art of bat manufacturing that after the bodies have been formed by blowing'fur upon a cone the next operation is the Wetting or as it is commonly called sinking of the bodies in a tank of water, which felts the fur sufficiently to permit the bodies .to be removed from the cone. This operation is usually performed by hand with the assistance of more or less crude mechanical apparatus. It has not however, so far' as we are aware been performed automatically. The objectionsto the ordinary method arethe slowness with which it is necessarily performed and the consequent expense of the operation, and furthermore that unless it is performed with great care the air within the cone is forced.

through the top of the body so rapidly as to frequently make holes in the bodies and thereby ruin them. Our novel machine performs the entire operation of wetting the bodies automatically, the bodies being lowered at a regular and positive speed without regard to the weight of the cone and in stantly raised again into position to be removed, all danger of injuring the bodies being wholly 'doneaway with. With these ends in view we have devised the novel mechanism which We will now describe referring by numbers to the accompanying drawings forming part of this specification, in which- Figure 1 is an elevation of our novel machine complete; Fig. 1, a detail sectional view on an enlarged scale on the line 5 s in. Figs. 1 and 1"; Fig. 1 a detail sectional view on the line w win Fig. 1*,looking toward the left; Fig. 2, an elevation on an enlarged scale of the clutch mechanism; Fig. 3, a section on the line a a: in Fig. 2 looking toward the left, the position of the parts in- Figs. 1, 2 and 3 corresponding; Figal, a view similar to Fig. 3 showing the reverse I position of the parts; Fig. 5, a section on the line y y in Fig. 4, and Fig. 6 is a section on the line 2 z in Fig. 1 looking down.

as on a cone 2 just as it comes from the forming machine. The cone and body are placed upon a suitable open support 3 carried by rods 4 which are connected by means of a cross piece 5 to a rope 6 passing over a grooved pulley 7 fixed toa shaft 8 journaled ii. suitable bearings 9 depending from the ceiling or supported by any suitable framework.

10 denotes a tank partially filledwith water and 11 guides secured to the top ofthe tank 1 denotes a hat body which is represented through which rods 4. pass so that the support and the cone and body thereon are held steady while being raised and lowered. Motion is imparted to the shaft by means of a belt, not shown, passing over a belt pulley 12 carried by a sleeve 13 which turns freely on the shaft.

14 is a pinion on sleeve 13 which meshes with a pinion 15,0n a short shaft 16 suitably journaled in proximity to shaft 8 and-carrying at its other end a pinion 17 which meshes I with an internal gear wheel 18 on a sleeve 19 which turns freely on shaft 8 and is also provided with a clutch member 20. The function of pinions 14,15,17 and the internal gear and is provided with an outwardly extending pin 25 and with a screw stud 26 the functions of which will presently be more fully explained.

27 is'an angle pin which extends outward IOO from sleeve 22 and then inward at an angle and is adapted to engage pin 25 on the loose collar as will presently be fully explained.

28 is a rigid depending arm which curves partially about sleeve 22 and is provided with an oblique slot 29 through which screw stud 26 passes.

30 denotes an anti-friction roller carried by the stud which engages the slot to insure perfect freedom of movement. The roller is preferably retained in operative position by means of a spring 31 which bearsagainsta washer 32 and against the head of the screw stud. See Figs. 4 and 5.

denotesa shaftjournaled in proximity to shaft 8 and carrying asprocket wheel 41 and a pinion 42. Motion is communicated to this shaft by means of a sprocket chain 43 passing over a sprocket wheel 44 on shaft 8 and over sprocket wheel 41. Pinion 42 meshes with a gear wheel 45 which is mounted on shaft 8 but is free to turn thereon and has formed integral therewith a ratchet 46 which lies within a socket 47 in a hub 48 rigidly fixed to shaft 8, as by a spline 49. Within socket 47 are pawls 50 which engage the ratchet and are held in contact therewith by springs 51.

36 is a collar on hub 48 having in its periphery a notch 52 which is adapted to be engaged by a swinging latch 37 as clearly shown in Figil to lock shaft 8, support 3, &c., at their normal position, that is, the raised position of the support.

38 denotes a cord which is connected with the swinging latch, passes over a pulley 39 and hangs down in position to be readily grasped by the operator when it is desired to release the shaft, support, &c., as in immersing a hat body on a cone, aswill presently be fully explained.

As a modification of the construction just described shaft 8 may be extended at the end opposite to that which carries pulley 12, see dotted lines Fig. 1, and provided with a pulley 33 to which a rope 34 is connected said rope having attached thereto a counter weight Rope 34 is wound in the opposite direction onpulley 33 from that in which rope 6 is wound on pulley 7 and the weight is suitably graduated soas to nearly butnot quite overcome the weight of the support and rods carried by rope 6 with the addition thereto of a cone. WVhen the downward movement of the cone, support, 850., takes place rope 34 is wound on pulley 33 and the counter weight is raised. The upward movement of the support, cone and hat body is produced in the the counter weight is at its highest position as is clearly shown in dotted lines in said figure.

The operation is as follows: It should be understood that while the machine is in use no faster.

belt pulley 12, pinions 14, 15 and 17, internal gear wheel 18, sprocket wheels 41 and 44, pinion 42, and gear wheel 45 are always in motion. Figs. 1, 2 and 3 show the parts in their normal position. Having placed a cone with a hat body thereon on support 3 as shown in Fig. l, the operator pulls cord 38 and removes the swinging latch from the notch in collar 36 which releases shaft 8 and permits the support with the cone thereon to sink into the tank, rope 6 unwinding from pulley 7 as the cone moves downward. When the movement just described commences angle pin 27 on sleeve 22 will be in the position shown in Figs. 2 and 3, and the shaft and sleeve will be rotated in the direction indicated by the arrow in Fig. 3 the loose collar remaining stationary until an instant later "as will be more fully explained. As soon as the shaft is released the natural tendency, owing to the weight of the support, cone, 650., is for the shaft to turn rapidly so that the immersion of the cone and body unless checked would take place so quickly as to force the airunder the hat body through the body itself to its serious injury. Except at just the times when the support, cone, &c., are being raised or lowered collar 36 is held stationary as already described and ratchet 46 is rotating the pawls slipping over the teeth of the ratchet. The instant however, that the collar is released the shaft commences to rotate and the support, cone, &c., commence to move downward. The pawls now engage the ratchet and the collar becomes the driving power. As the natural speed of the collar, shaft, &c., owing to the weight of the support and cone is greater than the speed of gear wheel 45, the ratchet, &c., which always rotate at a uniform speed, as already explained, and can move It will be understood, however, that it will be impossible for collar 36 to rotate any faster than it can drive the ratchet, gear wheel 45 and the parts operating in connection therewith all of which parts are constantly retained at their normal rate of speed by the driving belt, not shown, which passes over pulley 12. We thus insure that without regard to the weight of the cone, the support, cone andhat body will always sink at a uniform rate of speed which is made slow enough so that it will be impossible to force the air under the hat body through the body itself. Turning now to Figs. 2 to 5 inclusive, at the time the downward movement of the support, cone, &c., commences angle pin 27 is in the position shown in full lines in Fig. 3. Starting from this position said pin travels away from pin 25 making an entire revolution and engaging pin 25 on the opposite side as indicated by dotted lines in Fig. 3. As soon as this engagement takes place pin 25 is carried forward and with it of course loose collar 24 and screw stud 26. The rotary movement of the collar on the sleeve causes the roller and the screw stud to travel in oblique slot 29 in arm 28. 'As the arm is rigid it of course follows that the rotation of the collar must cause both collar and sleeve to slide on the shaft from the position shown in Fig. 2 to approximately that shown in Fig. 5, that is, to a position in which the clutch members engage. The instant this engagement takes place the downward movement of the cone and body stops and the up-' ward movement commences instantly. It will of course be understood that the rotation of the shaft during the downward movement of the support and cone just described rotates clutch member 21 in the opposite direction from The instant the engagement of the that in which it-has been moving and rope 6 is quickly wound on pulley 7 which raises the support, cone, &c., from the immersed position, see dotted lines Fig. 1, to the position in which the parts are shown in full, lines in said figure thus completing the operation and leavingthe cone and hat body in position to be removed and the support in position to receive another cone and hat body.

At the instant this position is reached latch 37 will pass into notch 52 in collar 36, thereby locking the parts at their normalposition as shown in Fig. l, in which position they remain until the operator again releases collar 36 by disengaging the latch from notch 52.

It will be seen that the entire operation of the machine both'in immersing and raising a hat andin locking the parts in their normalposition is automatic.

Having thus described our invention, we
