HAT-POUNCING MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 447,787, dated March 10, 1891.

Application filed May 29, 1889. Serial No. 312,539. (No model.)

To all whom it may concern:

Be it known that we, SAMUEL T. NEWMAN, of Danbury, in the county of Fairfield and State of Connecticut, and EDWIN O. OAKLEY, of Bethel, in the said county and State, have invented a certain new and useful Improveof the machine. Fig. 3 is a plan or top view.

Fig. i is an end view. Fig. 5 is an end view of the machine, looking from the opposite direction, certain parts being omitted. Fig. 6 is a vertical transverse section taken at the plane of the dotted line 00 00, Fig. 1, and looking in the direction indicated by the arrow at the end of this line. Fig. 7 is a horizontal section taken at the plane of the dotted line y y, Fig. 1, and looking upwardly, as indicated by the arrow at the end of this line. Fig. 8 is a sectional view of a pouncing-pad and certain parts with which it is combined. Fig. 9 is a side view of the pad as seen from a plane at right angles to that of Fig. 8. Fig. 10 is a sectional side view of a reversible pad. Fig. ll'is a view of a pad and the parts which support it. Fig. 12 is a View of another pad and the parts which support it. Figs. 11 and 12 are views taken from the side of the machine which is represented in Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

A designates the bed-piece of the machine. It may be made of metal or other suitable material and secured to a table or any other suitable support.

13 designates the driving-shaft of the machine. It is provided with a fast pulley b and a loose pulley b for receiving a belt used to transmit motion to the shaft. This belt may be shifted from the fast pulley to the The weight 0 serves to rock the shaft, so that it will swing the belt-shifter O in a direction to shift the belt onto the loose pulley. There is affixed to the rock-shaft C a handle or arm 0 whereby the shaft may be rocked and the belt-shifter swung so as to shift the beltonto the fixed pulley b to effect the rotation of the shaft 13. After the belt-shifter has been manipulated to shift the belt ontothe fixed pulley, it will be mainta ned in that position automatically by a mechanism devised for this purpose. lVe will defer a description of this mechanism for the present, as it will conduce to clearness to first describe some other parts.

The shaft B has affixed to it a balancewheel B, which has the additional function of a hand-wheel, which may-be grasped by the operator to adjust the shaft. At the forward end the shaft B is provided with a chuck D, which may be made of any approved type adapted to secure to the shaft a block E for sustaining a hat. In addition to the ordinary chuck we provide a positive lock between the block and the shaft B. This lock consists of an arm D bolted to the shaft and entering a hole in the rear of the block E. This insures the proper centering of the block upon the shaft.

Theblock E is intended to sustain ahat. While the hat is upon the block it will rotate with the block and the shaft B. During this rotation it will be subjected'to the actionof the pouneing-pads, of which we have shown 5 two G H. These pads may be of any desirable construction-as, for instance, they may motion, in conjunction with the rotary motion of the hat, enables the pads to operate upon all portions of the crown of the hat from the center of the tip right up to the brim.

The pad G has a shank g of tubular construction. In it is fitted a block g, which conforms to the shank as a piston conforms to a cylinder, so that the one is incapable of any movement except a longitudinal movement relatively to the other. The tubular shank has in it two opposite longitudinal slots Through these slots and through the block 9 passes a cylindric extension 9 of a lever g". A cross-pin passing through the extremity of the cylindric extension beyond the tubular shank of the pad secures the shank to the lever g. Obviouslythe pad may swing relatively to the lever g. This we have illustrated by dotted lines in Fig. 9.

In the tubular shank of the pad, between the body of the pad and the block g, is a spiral spring 9 which serves to force the pad against the hat. The lever g is fulcrumed between its ends by the pin g to a block g. The le- 2 5 ver swings upon its fulcrum to adapt the pad to its work. A spring 9 is attached to the outer end of the lever for the purpose of forcing the inner end downwardly toward the hat. At the upper end the spring is connected to a hook having a screw-shank. A nut combined with the screw-shank serves to adjustthe hook to vary the tension of the spring. This nut bears upon a bracket 9 secured to the block 9 The block 9 is secured to an arm g, which is made in the form of a cylindric shaft, although it differs from a shaft in that it has no rotary movement. This arm g is supported by a reciprocating slider I.

The pad H has a tubular shank h like the tubular shank g of the pad G. This tubular shank is slotted longitudinally like thetubular shank g. A pin h passes through the slots and through a block resembling the block g, arranged within the shank h. This pin it is at one end ailixed to a bar 7v. A cross-pin may be passed through the other end to retain the tubular shank upon the pin 70. The pad H can swing upon the bar h and a spring arranged within this tubular shank and combined therewith and with the block in the shank in the same manner that the spring 9 is combined withthe pad G and its block serves to force the pad 1-1 against the hat. The bar 7t" is supported by two arms 7L5 it. The arm 71. is rigidly secured to a sleeve h whichis supported upon the arm g and is free to rotate oroscillate around the latter. A spring 7L8, coiled around the arm g, bears upon the outer portion of the arm 7L5 and serves to press it toward the hat. This spring is shown as having the end portions coiled around the arm g and the middleportion bent into U form or V form, to straddle the arm 7r. The extremities of the spring are of course secured to the arm g. The arm 7:. is pivotally connected at the upper end by a pin h to the arm 71?. It has at about the middle of its length a longitudinal slot h Through this passes a thumb-screw h. This screw h also passes through the bar 7r at one end and at the other has a nut. By means of this screw and nut the bar 704 may be clamped in diiferent positions to the arm h. The upper end of the bar extends through a slot in the arm 7r. It. is secured within this slot by a screw h having a head on one end and a nut on the other. There are a number of holes in the arm 7L5, through which the screw h may bepassed to secure the bar 71; to this arm at different points in the length of the latter. There are also a number of holes in the bar it to enable the screws h h to be passed through it at dilferent points in its length. The connection of the bar It" to the arm g by means of the arms 7L5 and 7t enables the pad II to be adjusted and held in dilterent positions for operation upon the hat.

We have already explained that the arm is secured to a slider I. As this slider reciprocates, the pads travel over the hat, and in order to do this they swing at diiterent angles, being always free to yield, and yet held in contact with the hat by the action of the springs, which are combined with them.

The slider I is reciprocated by means of a wrist-pin t', aflixed to a worm-wheel I. This worm-wheelis supported upon a stud 2", erected upon a horizontally-extending part of the portion a" of the frame A. Motion is imparted to this worm-wheel by a worm B on the shaft B. A connecting-rod I extends be tween the wrist-pin 2'- and a pin i on the slider.

The slider I is composed of two sections i i The lower section 71 travels along shears or ways i on a bracket 2''", erected on the bedpiece A. The section 1 has a tongue-piece i,which fits in a groove in the section 2' To the tongue-piece 2' is secured a screw, which extends upwardly through the slot in the section i A nut i engages with the screw and bears upon the top of the section 2'. 3y means of this nut and the screw the tonguepiece 2' of the section i may be clamped to the section i The pin 1' is secured to the section 1. The arm 9 is secured to the section i". The movement imparted to the sec tion by the wrist-pin t' is of course always the same unless the connecting-rod is moved nearer to or farther from the ccnterot' wormgear and the amount of reciprocating motion imparted to the section '2? and the arm 1 and the appurtenances of the latter is also invariable unless changed, as mentioned above; but, owing to the fact that the section rmaybe adjusted lengthwise of the section i the reciprocating motion of the section 2', thea-rm g", and the appurtenances of the latter may occur at a different point relatively to the block E.

"We have already explained that the beltshifter after having been shifted to move the IIO belt onto the fixed pulley will be maintained automaticallyin such position. IVe will now describe the mechanism for this purpose.

J designates a slider-bar. It slides horizontally in bearings j, which are secured to the frame A. This bar has a lateral projection, here shown as made in the form of a screw-stud j, passing through a longitudinal slot 7' with which the bar is provided. The rock-shaft 0, having the arm 0 of the beltshifter affixed to it, has also affixed to it an arm C extending transversely to the arm 0, and approximately-in the direction of the length of the shaft 13. \Vhen the belt-shifter is adjusted to move the belt onto the fixed pulley b, the slider-bar J is adjusted by hand, so as to bring its stud j under that part of the arm 0 which is near the rock-shaft. The stud j will then support the arm 0 and hold the belt-shifter in position to maintain the belt upon the fixed pulley. cannot move while the stud j remains under the arm 0 The slider-bar J is, however, during the operation of the machine moved longitudinally to'carry its stud j beyond the arm 0 When the stud j has been moved beyond the arm 0 the weight C will oscillate the rock-shaft, and thereby swing the belt-shifter in such direction as to cause it to move the belt from the fixed pulley onto the loose pulley. The slider-bar is moved longitudinally by means of a pawl K, pivotally c0nnected to the lower end of a lever K, which is fulcrumed between its ends to the frame A.

To the upper end of this lever is connected a spring K This spring oscillates the lever in such direction as to cause the pawl to travel backwardly along a series of ratchet-teeth, with which the upper edge of the slider-bar J is provided. On the under side of the wormwheel I is a downward projection 2' having an outer curved or cam face. WVhen the camface contacts with the upper end of the lever K, it oscillates the lever in such direction that the pawl K will move the slider-bar J a distance equal to the length of one of the ratchet-teeth on the top of the bar. The slider-bar J will therefore be moved the distance of ratchet-tooth at each rotation of the worm-wheel. By connecting the screw-stud j with the slider-bar J in the manner described provision is aiforded for adjusting the position of this stud relatively to that portion of the slider-bar which is provided with the ratchet-teeth. This adjustment affords provision for varying the time that the stud will support the arm 0 and hence the time that the belt-shifter will maintain the belt upon the fixed pulley. The machine may therefore be adapted to pouncing different kinds of hats for the different periods which may be requisite. The pin 76, which connects the pawl K with the lever K, is rigidly affixed to the pawl, but passes loosely through the lever. The web of the frame A is provided Through this The belt-shifter hole the pin 7c passes. At the extremity of this pin it has affixed to it a handle This handle is near to the handle whereby the rock-shaft O. is oscillated. Hence the pawl may be disengaged from the ratchet-teeth of the slider-bar on the side of the machine at which the rock-shaft is operated.
