FRANK J. MURPHY, OF DANBURY, CONNECTICUT, ASSIGNOR OF ONE-HALF TO ANTHONY M. BUNDLE, OF SAME PLACE.

MACHINE FOR STlFFENING HAT-CROWNS.

SPECIFICATION forming part of Letters Patent No. 519,195, dated May 1, 1894. Application filed September 29,1893. Serial No. 486,780. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANKJ. MURPHY, a citizen of the UnitedStates, residing at Danbury, inthe county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Stiffening Hat-Crowns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othhas for its object to simplify and improve the construction and operation of the machine, the special purpose being by improvements in the details of construction to increase the product of the machine, the work being done just as well as heretofore, but the construction being such as to enable the operator to handle the hats more rapidly and to avoid loss of time between the finishing of the 0peration upon one hat and the commencement of the operation upon the next hat.

With these eudsin view I have devised the scale taken on the line x a: in Figs. 2 and 5 .illustrating the clutch mechanism and also the mechanism for operating the expansible cone; Fig. 4 a section on the line y y in Fig. 3 looking down; Fig. 5 a section on the line a z in Figs. 3 and .4; Fig. 6 an elevation corresponding with Figs. 3 and 5 the point of view being opposed to that in Fig. 3and from the right in Fig. 5; Fig. 7 an enlarged sectional view of one of the parts or arms of the 1 expansible cone showing .the mechanism for.

' clamping the hat body on the cone, and Fig.

8 is a plan View corresponding with Fig. 7.

1 denotes the bed of the machine which is supported by suitable legs 2, and is provided 5 5 shown as provided with two belt pulleys so I as to provide for different speeds for different classes of work. Motion is imparted to the carriage by means of a connecting rod 10 one end of which is pivoted to the tcarriage the other being adj ustably connected to gear wheel 5 so that theextent of movement of the carriage may be regulated at will.

11 and 12 denote respectively rear and front boxes in which shaft 8 is journaled. The rear boxiis provided with an arm 13 which is pivoted to a bracket 14 on a cross piece 15 between therear legs. Box 12 is provided with an arm 16 having a slot 17 and at its upper end a book 18. Abolt 19 passes through slot 17 and through a bracket attached to a cross piece between the legs the same as at the other end of the machine.

20 is aspring one end of which is connected to the under side of the bed the other being connected to hook 18 upon box 12.

21 is a foot lever pivoted to a bracket 22, and 23 is a link connecting the foot lever to box 12. i i 1 i The parts just described all appear in Fig.

1 in dotted. lines and are fully described in or. the said Patent No. 426,135. v

The operation is precisely as in the former patent. Spring 20 acts to hold the worm. in engagement with gear wheel 5 so that the carriage iscaused to reciprocate continuously 5 until its movement is stopped by the operator pressing down upon the foot lever and disconnecting theworm from the gear wheel.

24 denotes a spindle which is mounted in boxes 25 on standards 26 extending upward :00 from turning plate 27 which is secured to the -.carriage by a bolt 28.

29, see dotted lines Fig. 2, denotes anti-friction rollers upon which plate 27 rests and turns freely.

The cone used in my present machine is practically identical with the cone which forms the subject of my said former patent,

the lower end of which ispivoted to the turn- This lever is provided ing plate as at 33. with an enlargement 34 having an opening through which the slide passes, the connection of the lever to the slide being by means of screws 35 and 36 which engage a ring 37 lying in an annular recess in the slide. This I slide is secured to the spindle so as to turn which the shaft is journaled, and 43 a tank for the stiffening material. This tank is provided with a solid trunnion 44 and a hollow trunnion 45, the former engaging a box 46 and the latter engaging a box 47 which also receives a pipe 48 which is in line with the hollow trunnion, and the other end of which passes into hollow shaft 40 which turns freely thereon.

49 denotes a stop cock in pipe 48 for the purpose of cutting off the flow of stifiening material to the brush.

The tank is retained in upright position by, means of a set screw 50 in box 46 which engages solid trunnion 44. Should it be desired at any time to empty the tank of its contents, as for example for cleaning or for changing the quality of the stiffening material, this set screw is loosened which permits the tank to be turned on its trunnions and the contents Boxes 46 and 47 are carried by emptied out. standards 51 which are themselves supported by an extension 52 from the bed of the machine. The operating lever is locked in any required position after the cone has been expanded within a hat body by means of a special form of catch which I have devised for this machine, it being essential that the cone be locked rigidly in the expanded position and at the same time that the locking mechanism be so constructed that it will work smoothly and easily, and all danger of slipping in use shall be avoided.

53 denotes a plate which is secured to one of the standards 25 and is provided with a slot 54 and a rack 55.

56 and 57 denote upper and lower arms swung toward the sizing brush.

which are pivoted to the lever. The lower arm is provided with a lug or tooth 58 which engages the rack, the lug being held in engagement with the rack by means of a spring 59 which lies in a socket 62 in the upperarm and bears against the lower arm.

I 60 denotes arms which extend downward from arm 56 passing on oppositesides of arm 57 and the rack and between which is pivoted a roller 61 which engages slot 54.

63 is a hand piece which is pivoted to operating lever 32. A link 64 connects one arm of this lever with lower arm 57. In the present instance I have shown the link as passing through a slot in the upper arm.

The operation of the catch as a whole will be clearly understood from Fig. 3'in connection withFig. 1. The operator moves lever 32 forward as far as may be necessary to expand the cone to the required size. As the lever is moved forward lug 50 will move over the ratchet and will lock the lever against backward movement in any position in which it may be placed. To contract or collapse the cone the operator lifts the lug from the rack by means of the hand piece which leaves the operating lever free to be moved backward.

In order to insure that each hat body while upon the cone shall be operated upon evenly by the stiffening brush so that the bodies will be stiffened uniformly without regard to their size and the consequent expansion of the cone, I provide a stop 65, in the present instance a roller carried by plate 66 which is itself bolted to any suitable portion of the machine, said stop being adapted to' be engaged by an adj ustable guide plate 67 each time the turning plate, spindle, cone, &c., are This guide plate is pivoted to the forward end of the turning plate as at 68, see Fig. 4, and is provided at its rear end with an oblique slot 69. This slot is engaged by the lower end of a stud 70 which has formed integral with it a guide rod 71. The stud is provided with an anti-friction roller 72 which lies in the slot in the guide plate, the stud itself moving in a slot 73 in a plate 74 one end of which is bolted to the turning plate, the other end extending upward and over the end of the guide plate. Stud 70 is pivoted to enlargement 34 of the operating lever by means of screw 36,, see Fig. 5, which passes through the stud and through the enlargement of the operating lever, and the inner end of which engages ring 37. Guide rod 71 moves in a suitable support or guide 75 carried by a bracket 76 which is bolted to one of the standards 26. It will be seen that the guide plate is adjusted simultaneously with the cone so that each time the turning plate, cone, &c., are swung into operative position the cone must necessarily assume the proper posit-ion relative to the stiffening brush to insure that the entire length of the body be operated upon.

The hat bodies are retained upon the cone by a special form of clamp which I have de-- Any number of thesei clamps may be used, although I find in prac-j vised for this machine.

tice that two which I place directly opposite each other on the cone are quite sufficient.

77 denotes the clamping arm which is in shape an angle arm and is pivoted in ears 78 at the end of the piece or arm of the cone to which it is attached, see Figs. 7 andS. A spring 79 recessed in the end of the piece or arm of the cone acts against the inner side of the clamping arm to hold it in operative position. In order that the clamp may be adapted to all sizes of hat bodies I provide a dicated by 87.

operator lifts the long armof lever 83 which moves the short arm carrying roller 86 in clamping plate 80 which is adj ustably secured to the clamping arm by means of a screw 81 which passes through a slot 82 in the arm.

Theclamp is operated by meansof an angle lever 83which ispivoted between ears 84: upon the back of the clamping ar1n. One arm of this lever passes through a slot 85 in theclamping arm and is provided at its lower end with a roller 86 which bears upon the piece or arm of thecoue. The construction of the clamp will be clearly understood from Fig. 7. .It will be seen that in the normal position of the parts the angle lever is inactive and spring 79 acts to press theclam ping plate down upon the brim of the hat which is in- To release the hat brim the ward and lifts the clamping plate against the power of the spring. A stop 88 is pro vided to limit the movement of the short arm of the angle lever in lifting the clamping plate. The stop is placed in the exact posilion required to retain the clamping arm and clamping plate in the raised position that the short arm back past the center which will permit the spring to act to press the clamp ing platedown upon the hat brim.

Spindle 24 and the cone are driven by means of a belt 90, see Fig. 2, which 1 passes over a drum 89 which is itself loose upon the spindle. One end of the drum is provided with a tapering socket 91 adapted to receive a sliding cone 92 which is held against rotation on the spindle by means of a spline 93, but is free to move longitudinally thereon. of the incline of the cone, see Fig. 3, is an annular groove in which lies a ring 94.

95 denotes a lever which is provided with an enlargement 96 having an opening to receive the cone. Screws 97 pass through the enlargement of lever 95 and engage the ring. Thislever is pivoted to a bracket 98 extending from one of the standards26,and is con-V nected by means of a link 99 to an operating lever 100 which isitself pivoted tothe turning plate, see Fig. 4. A stop screw 101 isprovided in this lever which engages a stump 102 to limit the movement of the operating Back lever so that the cone cannot be-forced hard into the socket, it being simply necessary that the cone should engage the socket with sufficient friction to carry the spindle and cone. Said lever 100 is the main operating lever by which the operator swings the turning plate, spindle, cone, 850., into operative position and holds the hat body in contact with the stiffening brush and by which he re- 7 turns the parts to their normal position after each hat body has been operated upon.

103 denotes a wheel journaled on a stud 104 l which extends outward from the side of the bed. A rope 105 passes partially around this wheel and has at its lower end a weight 106.

On the inner side of this wheel is a hub 107 to which a chain or rope 108 is connected, the other end of said chain being connected to a hook 109 on the carriage. As shown in Figs. 1 and 2 it will be seen that the carriage,

spindle, cone, &c., are moving forward, that is toward the right. It is obvious that as this movement of the carriage takes place the weight will act to turn the wheelandconse quently to wind the chain upon hub 107. When the parts are in the position shown, the operator by means of lever 100 moves the sliding cone into engagement with the socket in the drum which necessarily imparts .rotation tothe spindle and the cone carrying the hat body, and by further movement of said lever, stop screw 101 being in contact with the stump, swings the turning plate, spindle and cone to the position shown in dotted lines in Fig. 2. The hat body on the cone is then in position to be operated upon by the stiffening brush, the operator holding the cone and hat body in this position by means of said lever 100, while the cone moves forward in ICC contact with the brush. As soon as the stififening operation is completed the operator using only said lever 100, moves the turning plate, spindle and cone back to their normal position and also disengages the sliding cone from its socket so that rotation of the spindle and cone ceases instantly. During the backward movement of the carriage, turning plate,

850., the operator removes the hat body that has been stiffened and places another hat body thereon, it being simply necessary to manipulate the two clamps as already described to release one hat body and secure another in position. By the time the backward movement of the carriage and parts carried thereby is finished the new hat body will be ready tobe operated upon. It will be apparent from Fig. 1 that while the carriage has been moving backward, that is toward the left, a portion of rope 105 will have been wound uponwheel 103 and the weight will have been lifted. When the parts are in this positiomin order to avoid loss of time, and so that the stiffening operation upon a new hatmay be commenced instantly the operator presses down upon the foot lever 21 and disengages worm7 from the gear wheel. This leaves the carriage free to be drawn forward by the weight, which the instant the gear wheel is released winds the chain upon hub 107 and draws the carriage. forward so that the hat body upon the cone may be swung into position to be acted upon by the stiffening brush. I thus make a great saving of time, as the carriage, spindle, cone, 850., will move instantly from the extreme retracted position into the position in which they are shown in Figs. 1 and 2. In practice a suitable support, for example abracket 110 as shown in the drawings, is provided for the weight to rest upon at the extreme of its downward movement, that is to say the rope is given just the required length so that at the instant the weight comes in contact with the support and the forward movement of the carriage is stopped, the carriage, spindle and cone will have been placed in sucha position that the cone may be swung inward and will place the tip of the hat body in position to be acted upon by the'stiffening brush as the carriage is moved forward by the worm and gear wheel, it being of course understood that the operator removes his foot from foot lever 21 gear wheel, of wheel 103 having a hub 107, a; chain connected to the carriage and to said hub, aweight, a rope connected to said weight and passing partially around the wheel, and

a support for the weight whereby the forward movement of the carriage is limited said parts being so arranged that when the carriage is moved backward the rope is wound on the wheel and the weight lifted, and when thedriving mechanism is disconnected from the gear wheel the weight will act to draw the carriage forward independently of the gear.
