MACHINE FOR DIPPING HATS.

SPECIFICATION forming part of Letters Patent No. 549,684, dated November 12, 1895.

Application filed March 29, 1895. Serial No. 543,688. (No model.)

, T aZZ, whom it may concern.-

Be it known that I, CHARLES S. PEOK, a citizen of the United States, residing at Danbury,

in the county of Fairfield and State of Con necticut, have invented certain new and useful Improvements in Machines for Dipping Hats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the class of machines for dipping hats whichis illustrated and de scribed in my pending application for Letters Patent,SerialNo.525,238,filed October 8,1894, and has for its general object to still further simplify and cheapen their construction and to improvetheir mode of operation in use, the special object of my present machine being to provide a construction especially adapted to certain classes of work'as, for example, in the manufacture of bonnets or fine hats in which it is desirable to have the upward movement of the carrier, cone, and hat-body take place at the greatest practicable speed. In order to accomplish the desired result I have devised a machine in which the downward movement of the carrier is produced by mechanism which is automatically disconnected from the driving mechanism at the end of the downward movement, permitting the upward movement to be performed very quickly by means of a weight, automatic mechanism being provided as in mysaid former application referred to for determining the length of time during which the body shall remain sub merged. My invention furthermore relates to vari ous improvements in the details of construc-.

tion which I will now proceed to describe, and then specifically point out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the machine complete, with the exception that the bracket which carries the operating-rod is in section; Fig. 2, an enlarged detailed perspective, partially in section ,ill ustrating the sleeve at the outer end of the main shaft which carries the dipping-wheel, a stop, and one of the elliptical gears; Fig. 3, a section on the line 02.00 in Fig. 1, looking toward the right; Fig. 4, a detail perspective, on an of the automatic mechanism which determines the length of time the body shall remain submerged; Fig. 5, a detail elevation, partially in section, of the mechanism illustrated in'FigJeL; Fig. 6,a section, on an enlarged scale, on the lllle flj 'y in Figs. 1 and 3, looking up; Fig. 7, a section on the line 2 z in Figs. 1 and 6, looking toward the right; and Fig. 8 is a section on the line 3 s in Figs. 1 and 6,

also looking toward the right, shaft 23, however, having made a half rotation and the dipping mechanism been disconnected, Figs. 6, 7, and 8 illustrating the construction and op eration of the mechanism for connecting and disconnecting shaft 23 and the dipping mechanism.

1 denotes a frame which may be of any ordinary or preferred construction and is usually adapted for attachment to the ceiling or to overhead beams. It may, however, if preferred, be supported by standards. (Not shown.) Power is applied to drive the machine by a belt 2 running over a cone-pulley3 and passing through a belt-shifter 4. of ordinary construction.

5 denotes a shifting-lever which is provided with a latch 6, adapted to engage notches in a plate 7 to lock the belt-shifter and belt in operative position.

The use of a cone-pulley enables-me to increase and decrease the speed of the machine by simply moving the shifting-lever in either direction, as may be required. The conepulley is carried by a shaft 8, which is suitably journaled in the frame, and is, in fact, the main shaft of the machine.

9 denotes a pinion and 10 a spiral gear on shaft 8.v vThe opposite end of shaft 8 is reduced, as at 11, and carries a sleeve 12, which has formed integral with it a stop 13.

14 denotes an elliptical gear, whose hub 15 is rigidly secured to the sleeve as, for example, by a setscrewe-as shown in Fig. 2. Outside of the elliptical gear is the dippingwheel 16, whose hub 17 is also rigidly secured to the sleeve. The dipping-wheel may or may not be a sprocket-wheel, as shown in the drawlngs. V

18 denotes a sprocket-chain, which is secured at one place to the periphery of the dipping-wheel, as at 19 in Fig. 3. At one end enlarged scale, illustrating the construction of the chain (a rope or cord may of course be substituted, if preferred) I attach a weight and atthe other end I attach the usual car rier 21, upon. which the cones, with hat-bodies thereon, are placed for submersion in the tank, which is indicated by 22, the cone be- :ing indicated by b, and a hat-body thereto by c.

23 denotes a shaft, which is suitably journaled on the frame, in the present instance, above shaft 8.

2% denotes a large gear-wheel having a hub 25, which turns freely on shaft This gearwheel meshes with pinion 9, and is always turning when the machine is in use. The inner face of gear-wheel 2st is provided with crown teeth 20, which are adapted to be engaged by a lug 27 on a sliding block 28, carried by an arm 90, which is rigidly secured to shaft 23. I have shown this block as provided with ribs 32, which move in ways at the sides of a recess 30 in the arm and as moved forward by a spring 31, socketed in the recess below the block. (See Fig. 0.) Upon the outer face of the block is a rigid latch 33, which is adapted to engage a lever ill, pivoted to an arm 35, depending from a block 36, which is rigidly secured to or cast integral with a bracket 37, (see Fig. (3,) the latter being rigidly bolted to the frame, as shown in Fig. 1, in which the bracket ap pears in section. The special shape of this lever is, of course, not of the essence of my invention, the essential requirements being a surface 38 for engagement by latch 33, a notch 39, adapted to engage a pin 10, projecting outward from the block, a notch l1 and a surface l2, both of which are adapted to be engaged by a stump l3, which lies in a slot ii in block 30, said stump projecting outward from a block 45, which is adapted to slide in a recess 4:6 in block 36, said block l5 being normally held at the raised position by a spring -l7, soeketed in recess it; below the block. (See Fig. 7.)

l8 denotes a rod connected to block 45, which 1 term the operating-rod. This rod passes down through spring 47 and through block 36, and has attached thereto, in the present instance, acord 40 for convenience in operation.

\Vhen it is desired to dip a hat-bod 3 the operator is simply required to pull upon the operating rod or the cord, and from this instant the operation of the machine in lowering a hat-body into the tank, retaining it submerged for any required length of time, which is determined by adjustment, and raising the cone and hat-body, is wholly automatic, as will presently be fully explained.

The normal position of the parts just described is shown in Fig. 7. When the operator pulls down upon the cord, he moves block downward far enough to permit spring 31 to move sliding block 28 forward, and places lugs 27 in engagement with crown-teeth 26 on the large gear-wheel latch 33 at the sametime moving lever 31. forward until stump l3 lies in notch -l-1. The aetualengaged position of the lug with the crown-teeth is not shown in the drawings, but will be readily understood from Fig. 5 and from Fig. 1, it being obvious from. Fig. (5 that the forward movement of the lug will place it in engagement with the crown-tooth at the top, and 1 showing a position in which the engaging lug registers with a space between two crown-teeth from which position it would simply move forward toward the point of view in order to be in engagement with the teeth.

It will be noticed in Fig. 7 that notch 41 and stump 4.35 are both rounded, so that the instant latch 33 has passed off from lever 34 spring l7 will. raise block 45, and stump 43 will pass out of notch l1 and will move the lever back to the position in which it is shown in said figure, the backward movement of the lever being stopped by pin it), as clear] y shown. The parts remain. in this position until shaft 23 is started again bya pull upon the operating-cord.

denotes an arm similar in construction to arm 2!) and likewise rididly attached. to shaft 23. In the presentinstanee I have shown these two arms as formed integral with a sleeve 51, which is keyed or otherwise secured. to shaft 2 3. 52 denotes a cam on this sleeve, the purpose of which will. pressently be fully explained. Arm 50 is provided with a recess 53, which receives a sliding block 54:, having ribs 55 engaging ways at the sides of the recess, and which is moved forward by a spring 56, soekcted in the recess below the block. Block 54: is likewise provided with. a lug 57 and a rigid latch 58, the functions of which will n'esentlybe fully explained.

59 denotes a sleeve on shaft 225, which is adapted to turn freely thereon and has formed integral therewith or rigidly secured thereto an arm 60, provided. with a lug (31., which is adapted to be engaged by lug 57 on sliding block 5;. The sleeve itself is journaled in a bearing on. the frame, this end of the shaft being as a matter of fact journaled in the sleeve. The bearing is indicated by 62. At the outer end of the sleeve is an elliptical gear 623, whose hub (it is rigidly secured to the sleeve -as, for example, by a set-screw. This gear meshes with elliptical gear 14, car- .ried by sleeve 12, which itself rotates on the main shaft,designated as S,the dipping-wheel, as already stated, moving with this gear.

The operation of this portion of my invention is as follows: The instant that lu 27 on sliding block 28 becomes engaged with the crown-teeth of the large gear-wheel, motion is imparted by means of arm 29 to shaft 23, sleeve 51, and arm 50. Lug 57 on slidingblock 5i now engages lug 61 on arm and carries sleeve 59, and with it elliptical. gear 63, forward with it against the power of the weight, the effect of which is to lower the carrier and with it the cone and hat-bodyinto body shallmove downward with a gradually on the rod being limited by a pin 68.

effect of the engagement of latch 33.with cam retarded movement. By the term retarded I mean that the downward movement commences at the maximum speed and gradually grows slower to the end of the movement, so that there shall be no danger whatever of forcing the air within the body through it violently, so as to rupture or injure the body.

'In Figs. 1 and 3 the parts are shown at the normal positionthat is, with the carrier at the raised position and having a cone and hat-body thereon. It will be noticed that at the starting-point the long radius of elliptical gear 63, which is the driving-gear, registers with the. short radius of elliptical gear 14,,whichis the driven gear, and that as the movement proceeds thev operative radius of the driving-gear will constantly grow shorter and the operative radius of the driven gear will constantly grow longer, thus producing a constantly-retarded movement of the driven gear and driven shaft and with it, of course, the dipping-wheel and carrier. At the instant the carrier reaches the lowered position in the tank, the movement is stopped in the manner I will now describe.

IVhen the carrier is in this position, arms 29, 50, and will be at the position shown in dotted lines in Fig. 6, (see also Fig. 3,)

which shows thedotted position of arm 60,

and also of stop 13 on sleeve 12. At this instant latch 33 on sliding block 28 will have engaged a cam on a sliding collar 66 on a rod 67, the respective ends of which are rigidly securedin the frame, as indicated in Fig. 1, the downward movement of collar 66 The 65 will be to force the latch and with it the sliding block and engaging lug backward, as clearly indicated by dotted lines in Fig. 6, and will move said lug out of engagement with the crown-teeth on the large gear-wheel, thus instantly stopping the rotation of shaft 23, in which position the carrier with the cone and hat-body thereon will be wholly submerged. The carrier, cone, and hat-body will remain in this position until they are raised in a manner I shall presently describe, and shaft 23 and arms 29 and 50 will remain stationary until lug 27, on sliding-block 28, is again placed in engagement with the crown-teeth on the large gear-wheel, as will be fully explained. In order to insure that shaft 23 will be locked in position instantly when it has completed each half-rotation, I ordinarily provide suitable stop mechanism, which as a whole I have indicated by A in Fig. 1. The stop mechanism I'preferably use consists of a plate 73 at the end of shaft 23, which is provided on opposite sides with notches (not ShOWIl) c-Lu.

adapted to be engaged bya roller (not shown) carried by an arm 74., which in the present instance is pivoted on shaft 8. The roller is held in engagement with the periphery of the cam and is forced into the notches by a spring (not shown) carried by a bracket 75, rigidly secured to the frame. I have not deemed the stop mechanism to require explanation in detail, for the reason that stop mechanism is not essential, and if used any stop mechanism will serve the purpose, although I preferably use the stop mechanism illustrated and described in my said former application referred to.

As already stated, the parts are shown at the normal position in Figs. 1 and 3. Stop 13, which is fixed to sleeve 12, which also carries the dipping-wheel, now rests against a cushion 95, carried by a bracket 96, bolted to the frame. At the completion of the half-rotation of shaft 23, just described, stop 13 will be in the positionindicated by dotted lines in Fig. 3, and arm 60, carried by shaft 23,will also be in the position indicated by dotted lines in said figure. As arm 60 approaches the extreme of its movement in this direction, it engages a starting device 97, in the present instance a plunger, the lower end of which is s'ocketed in a block 98, carried by a bracket 99, bolted to the frame. A spring 100, lying under the plunger, acts to move it to the raised position. This starting device may or may not be used. I find it desirable, however, when stopping mechanism-such, for example, as the mechanism I have indicated by Ais used to lock shaft 23 in position at the end of each half'rotation to use a spring or a spring-actuated plunger to start arm 60 on its return movement when it is released, as I shall presently describe. It will be understood that arm 60 presses the plunger down against the power of the spring, and that when the arm is released the resiliency of the spring will act to start the arm quicklyon the return movement.

Turning now to Fig. 4, but referring also to Figs. 3 to 8, inclusive, I will describe the manner in which the carrier with the cone.

and hat-body thereon are returned to the normal position, and also the manner in which shaft 23 is again connected with the large gear-wheel and carried forward thereby and again disconnected therefrom at the end of the second half-rotation, the parts being then again at the normal position and ready to receive another cone and hat-body to be dipped.

69 denotes a cam on a sliding collar '7 0 on a rod 71, the respective ends of which are secured in the frame, as indicated in Fig. 1, the downward movement of collar 70 on the rod being limited by a pin 72. This cam is adapted to be engaged by latch 58 on sliding block 54,

as I shall presently explain.

76 denotes a rod, the respective ends of which are rigidly secured in the frame, and 77 ablock adapted to slide thereon. 79 denotes a screw-shaft, the ends of which are l l V A. I

journaled in hubs 86, themselves rigidly secured to the frame.

81 is a collar on the screw-shaft, which bears against the upper hub to prevent upward movement of the shaft, and 82 is a spiral gear on said shaft, which rests upon the lower hub and meshes with spiral gear 10 on shaft 8, by which the screw is kept continually in rotation when the machine is in use. The spiral gear on screw-shaft 79 is shown only in dotted lines in Fig. 1, the entire construction, however, being fully illustrated and described in my said former application referred to. At the outer end of block 77 is a recess 83, through which screw-shaft 79 passes, but without e011- tact therewith. Pivoted in this recess is a lever 84, which carries a block 85, the face of which is threaded to correspond with the thread of the screw-shaft. A spring 86 acts to hold the threaded block normally out of engagement with the thread of the screwshaft, as indicated in Fig. 1. (See also Figs. 5 and '7.) At the completion of the half-rotation of shaft 23 the back of lever 8% will be engaged by cam 52 on shaft 23, and block 85 will be forced forward thereby against the power of the spring and placed in engagement with the thread of the screw-shaft. The normal position of the cam relatively to the lever is indicated by dotted lines in Fig. 7. The operative position of block 85 is not shown, it being deemed unnecessary to describe this portion of the mechanism in detail for the reason that it is fully illustrated and described in my said former application referred to. It is suflieient to say that at the completion of each half-rotation of shaft 23 and the parts carried thereby cam 52 will force lever 84 inward and will place the threaded block in engagement with the thread of the screw-shaft. As the screw-shaft is continually in rotation, it is obvious that when the threaded block is in engagement therewith the rotation of said shaft in. the direction indicated by arrows in Figs. l and 5 will raise block 77 on red 76, by which it is carried.

87 denotes a lug projecting outward from block 77 and which is engaged by a rod 88, a portion of which is threaded. At the lower end of this rod is a hand-wheel 89 for convenience in operation. 90 denotes collars on said rod, which are secured thereto in any suitable manner and which retain between them a collar 91, not secured to the rod, said collar 91 carrying a yoke 92, which partially incloses rod 76. It will be obvious that rotation of rod 88 will raise or lower said rod through the engagement of the thread thereon. with lug 87 on block 77, and will consequently raise yoke 92 relatively to the block. Sliding collar 66 is provided with an arm 93, having an opening through which rod 76 passes freely, and sliding collar 70 is provided with an arm 9i, also having an opening through which rod 7 6 passes freely.

The operation of this portion of the machin 0 is as follows: \Vhen the rotation of shaft 23 causes cam 52 to engage lever 84 and place the threaded block in engagement with the screw-shaft, block 7 7 and with it rod 88 and yoke 92 will be moved upward thereby, said yoke first engaging arm 94 on sliding collar 70 and raising said arm and with it the collar and cam 69. As the cam is moved upward, it engages latch 58, (see dotted lines Fig. 6, also Fig. 8,) and moves sliding block 5i and with it lug 57 backward again st the power of the spring. In Fig. 6 1 have shown in dotted lines the position of lug 57 when moved. backward, the lug being shown as moved inward past lug 61 on arm 60, thus releasing the arm. The instant the arm is released weight 20 will act to return the dipping-wheel, carrier, &e., to the normal position. This return movement of the carrier takes place very quickly, as the in.- stant the release takes place the starting device acts upon arm to start it forward, and the weight is made suflieiently heavy to more than overcome the weight of the carrier and cone. Just before the end of the upward movement is reached the weight comes in con tact with a stop (not shown) as, for example, the floor which stops the action of the weight upon the d ipping-wheel. An instantlater the upward movement of the carrier is stopped by the engagement of stop 13 with cushion 95. After the release of arm 60, through. the engagementof latch 58 with cam 66, yoke 92 will continue to move upward, carrying collar 70 and arm 94:, until the latter engages arm 63 on sliding collar 66 and carries said arm and with it collar 66 and cam upward also. This movement raises cam 65 out of engagement with latch and permits lug 27, on sliding block 28, to again engage the crownteeth 011 the large gear-wheel, thus again communicating motion to shaft 23. The instant shaft 23 commences to move again cam 52 on said shaft passes out of engagement with lever Si and spring 86 moves the threaded block out of engagement with the screw-shaft. This, of course, releases block 77 and permits it to drop down on red 76 until it is stopped by arm 93 on sliding collar 66. It will be readily understood from the description already given that until eam 69 on. sliding collar 70 is raised suiliciently to disengage lug 57 from lug 61 the hat-body, which has been lowered into the tank, will remain submerged. The length of time that the body remains submerged will depend, of course, upon the adjustment of yoke 92, which is carried by red 88, it being apparent that if said yoke is raised high enough, so that it will. engage arm Dian instant after latch is moved back by cam 65 and engaging-1w 27 thrown out of en gagement with the crown-teeth, the upward movement of the hat-body will commence immediately, and that just as long a period of submersion as may be required can be obtained by rotating rod 88 and moving yoke 92 down.- ward, where it will remain until readjusted,

it being, of course, understood that collars 9O rotate with the rod, so that the rod turns freely in collar 91, which carries the yoke.

It will be noticed in Fig. 5 that in the normal position of the parts there is a little space between arms 94 and 93. This space is not essential, although in practice I preferably place these arms a short distance apart on rod 7 6, so that a brief period of time will elapse after the release of arm 60, during which time arm will return to its normal position and the carrier, cone, and hat-body will be raised before the second half-rotation of shaft 23 will commence. During the time that elapses after the carrier has reached its normal position, and before the second halfrotation of shaft 23 is completed, the operator removes the cone and hat-body from the carrier and places another thereon ready to be dipped, thus effecting a great saving in time and allowing the cones with the hatbodies thereon to be handled much faster than has heretofore been possible, the upward movement being almost instantaneous, and the entire operation of dipping a hat consuming but little time in excess of the time required for the downward movement and the time during which the body remains submerged. The movement of shaft 23, which commences the instant engaging-1n g 27 passes the second time into engagement with the crown-teeth on the large gear-wheel, will continue until the second half-rotation of this shaft is completed and latch 33 has engaged surface 38 on lever 34: and been moved backward, thereby carrying the engaging-lug out of engagement with the crown-teeth, as will be clearly understood from Figs. 6 and '7, (which see in connection with Fig. 1,) and stopping the machine the instant the second half-rotation is completed, the carrier with the cone and hat-body thereon being now at the raised position, as has already been fully explained.

It is believed that the operation of the machine as a whole will be clearly understood from the description of the several mechanisms. A general description of the operation is therefore not thought to be required, it being sufficient to say that having started the machine by a pull upon the operating-cord the first half-rotation of shaft 23 is automatically stopped by the engagement of latch 33 with cam 65,which disconnects the shaft from the large gear-wheel. This half-rotation of the shaft will have lowered the carrier and with it a cone and hat-body into the tank in the present instance with a retarded movementthe sleeve carrying the dipping-wheel being connected by gears with an arm 60, journaled on shaft 23, and said arm being connected to the shaft by a lug 57, which engages lug 61. on sliding block 54, which also carries latch 58. At a predetermined time cam 69 is movedupward by yoke 92 and engages latch 58,forcing the block backward and disengaging arms 60 from the shaft. The weight now returns the dipping-wheel and carrier to the normal position, the upward movement of the carrier being stopped by the engagement of stop 13 with cushion 95, the length of time that the hat-body on the cone remains submerged being determined by the adj ustment of the yoke on the rod by which it is carried. The second half-rotation of shaft 23 is automatically stopped by the engagement of latch 33 with lever 34:, which again disconnects shaft 23 from the large gearwheel. The parts are now at the normal position. All the operator is required to do to dip a hat-body is to place a cone with a body thereon on the carrier and pull the operatingcord, the entire operation of dipping being automatic.
