HAT-BLOCKING MACHINE.

SPECIFICATION formingpart of LettersPaten't N o. 724,404, dated March 31, 1903.

Application filed August 12, 1902. Serial No. 119,446. (No model.)

To (LM whom, z'tvmty concern-f Be it known that I, ARTHUR B. WARING, a citizen of the United States of America, and a resident of Yonkers, county of Westchester, and State of New York, have invented certain new and useful Improvementsin Hat- Blocking Machines, of which the following` is a specification.

The present invention relates to hat-blocking machines. -Until now hats have been blocked in the rough while wet,then dried and pounced. Although when the hats are blocked in the rough they are lnanipulated so as to produce as near as possible the desired shape and size, the shrinking of the hat-body during this process of drying makes the hats very irregular in shape and size. To produce the actual final shape and size, the-hat-body is generally held in steam by the workman, pulled by hand over a wooden block, and the crown and brim ironed and flattened. There are no machines which do this work satisfactorily. The process is difficult and laborious.

The objects of my. invention are to do away with practically all of the hand labor now-re sorted to in shaping the crown and ironing the brim ofthe hat and to do the work in a superior manner, to provide a machine several of which may be operated by one person, thus enabling a much greater output per operator than heretofore, and generally to provide a machine whichis efticient and reliable for blocking in the finishing-room felt hats to their final desired shape and size.

Some of the characteristic features of my invention are.that a heated hat-block is used in combination with heated brim clamps, thus shaping the crown and flatteningand ironing the brim to the desired iinalshape and size in one operation;-that the upper and lower brim-clamps are both furnished with steam-chests; that the hat-block is adjustable and thatthe whole hat may be steamed automatically during the operation of the machine; that one of the brim-clamps is cushioned or spring-pressed, and the whole general makeup of the machine and coperating parts is such that the method of blocking hats by hand is well imitated in all its steps and done in a rapid and superior manner.

My invention consists of certain features of construction and combinations of parts to be hereinafter described and then pointed out in the claims.

In the accompanying six sheets of drawings, which illustrate one embodiment of form, structure, and combination of which the parts of the invention are susceptible, Figure 1 is a front elevation ofahat-blocking machine, showing my invention, the machine being at rest or in receptive condition.

Fig. 2 is a side elevation as viewed from the right of Fig. l. Figs. 3, 4, and 5 are detail views showing the steam-controlling devices, Fig. 3 showing the same in side View, steam being supplied, Fig. 4 showing the same in side view, steam being shut off and 'theupper clamp permitted to rise without acting on the steam-valve, and Fig. 5 showing the same partsin plan, the valve-actuator or shoe being omitted. Fig. 6 is a vertical. central section cf the machine, parts innelevation. Fig. '7 is an enlarged under side view of the hatblock. Fig. 8 is a detail vertical section, parts broken away, showing the means for adjusting the hat-block. Fig. 9 is an enlarged transverse section on line IX IX, Fig. 8. Fig. 10 is a section similar to Fig. 6, in which the brim-clamps are shown closed and. the hatblock raised as in blocking a hat. va horizontal section through the steam-chest Fig. 11 is same parts, in which the position topwhich the same are moved to start the machine is shown. Fig. 15 is a perspective view ofvsame in the position in which the clutch is disconnected and the machine is' blocking at re'st. Fig. 16

is a detail perspective View showing only parts of the clutch-operating mechanism in position in which the clutch has been again thrown to release the hat; and Fig. 17 is a detail view of the clutch, showing'it open in'full lines and IOO steam-pipe 35.

from shaft 4 by a pinion 8 and a gear-wheel 9, so that shafts 2 4 5 have a rate ot' speed greater the one over the other in the order named.

Fixed at the upper part of the trame 1 is a steam-chest 10, having a hat-brim clamp l1,Y the clamp 11 being preferably formed by the upper surface of the steam-chest. The upperv brim-clamp 12 is preferably for-med by the lower surface ot' an upper steam-chest 13, which is mounted on the upper ends of supporting-slides 14 in the form of squared rods,

whichV move in suitableguides 15116 at the sides of the frame l, so as to clamp the hatbrim between the brim-clamps 11 12 or to release the brim therefrom. To this end the slides 14 of the upper brim-clamp and steam.- chest are connected by links 17 with oscillatory levers 18, pivoted at 19, the said levers being oscillated by means of tappets 20, fixed on the shaft 5. The upward movement of the upper brim-clamp is accomplished by the outer end of the tappets 2O bearing against the lower edges of the levers 18, while the downward movement thereof is accomplished by the weight of the steamchest and attached fparts, the final pressure being obtained by the bearing of the tappets on straightbearing-pieces 22, joined adjustably to the stirrups hy set-'screws 23, which pass through slots (not shown) in'V the stirrups. This final pressure quickly compresses helical springs 24, which are located on the rounded upper ends of the slides 14 and are confined between nuts 25 and ears 26 on the upper steam-chest and brim-clamp, said ears guiding the slides loosely and permitting the same to move down farther after the upper brimclamp has been clamped upon the lower brimclamp. In this way a cushioned or springpressed upper brim-clamp is provided, so that vthe pressure will not be hard and unyielding, while at the same time the said brimclamp will always clamp down upon hat-brims .of various thicknesses.

Each brim-clamp as well as steam-chest is provided with acentral opening 27 28, respectively, to receive a hat-block, such as 29, which forms a male member, while the brimclamps form two female members. A horizontal section ot' the upper steam-chest is shown in Fig. 11, from which it will be seen` that the same has a transverse partition 30 at one side, on one side of which is connected at inlet steam-pipe 3l, while at the other side an outlet steam-pipe 32-is connected. The lower steam-chest 10 has a similar partition 33, an inlet steam-pipe 34,y and an outlet Both the upper and lower brim-clamps are thus heated.

The brim-clamps are equipped with flat templets 36 37, respectively, templet 37 being simply laid upon or fastened to the lower brim-clamp and templet 36 having studs 38, which pass through the upper steam-chest and receiveat their upper ends thumb-nuts 39, whereby the templet 36 is firmly secured to the brim-clamp l2. Various sizes of templets are provided for use with the machine, which sizes accord with a like number of head-sizes of hat-blocks.

Hat-block 29 is supported on a plate or table 40, which is connected for adjustment with reciprocating rod 41,that moves in guides 42 of the frame 1, and has a fixed sleeve 43, to which isl pivoted one end ot each of two links 44, the opposite ends of which are pivoted to the forked end of a lever 45, pivoted at 46. The lever 45 is oscillated by a tappet '47 on the shaft 5 to elevate the hat-block,

which lowers by gravity, as do the upper brim-clamp and steam-chest also. The hatblock 29 is shown in Fig. 7 provided with a cross-piece 48, having concentric with its centering-hole 49 two edge notches or recesses 50, which are engaged by headed studs 51 on the block-plate 40 when a short turn is imparted to the hat-block, thereby locking the hatblock in place. The hat-block is hollow, so as to form a chamber 52, it beingin the form of a metallic shell having the proper contour for the hat-crown. It is .made Vhollow not only for lightness, but mainly to receive a suitable amount of heat and to retain the same in its' chamber 52, to which end an an-V nular perforated burner 53 is located under the plate 40, it being supported adjustably thereon by clips 54, which are screwed like nuts onto screw-threaded pins 55 on the under side of the said plate. A gas-supply pipe 56 leads to the, burner.

In Figs. 8 and 9 the means for raising and lowering the block-plate 40, so that the block will normally protrude more or less above the lower brim-clamp 1l, is-shown. This Vmeans consists of a screw-spindle 57, formed as an extension of the block-centering pin 58 and which screws into the upper end of a cap-like adjusting-nut 59, that its over the hollow upper end of the slide-rod 41 and has tapped thereinto conning-screws 60, the ends of which protrude into an annular groove 61 in the upper end of the slide-rod and prevent the longitudinal movement or" the adjustingnut 59, while permitting the same to turn. The turning of the adjusting-nut 59 is done by a hand-wheel 62, the hub of which is secured to a portion of the nut by a set-screw 63. To compel the spindle 57 to move longitudinally without turning, the same is provided With A a longitudinal groove 64, into which protrudes the .end of a guide-screw 65, which is countersunk in the hollow upper end ot the slide-rod 41. The screw 65 precludes the turning of the spindle; but as the latter may move longitudinally theturning of the nut acts to feed the spindle up or down, as the ,case may be.

Prior to the closing of the upper brim-clam p `and the entrance of the hat-block thereinto the hat is steamed. For this purpose a perforated steaming-ring 66 is mounted on suitable hangers67 on the underside of the steamchest 10, steam being supplied thereto by a IOO ITO

'valve-controlled supply-pipe 68. The valve 69 works against a valve-seat (indicated in dotted lines in Fig. 5) and its spindle 70 is engaged by an actuating-arm 71, pivoted to a bracket 72 at one end and at the other end Vcarrying a pivoted gravity-dog 73, the free end of which is located in the path of a pressure-shoe 74, fixed to a slide 14 and extending upwardly alongside it. In raised position of the upper brim-clamp the free end of the dog extends into a recess or cut-out 75 in the shoe 74, and when the said clamp is being lowered the dog, not being free to yield in downward direction, is engaged,as shown in Fig. 3, so as to press on and open the valve 69, and steam is then supplied to the hat on the hat-block through the opening in the lower clamp. When the shoe passes below the dog, the pressure on the valve is removed and the valve closes. During the upward movement of the upper brim-clamp the shoe 74 strikes the dog and simply swings it on its pivot without action onthe valve, as shown in Fig. 4.

Mechanism for throwing the clutch into and out of action for starting and automatically stopping the machine will now be described. This mechanism is shown more or less in most of the views; but it is shown in detail in Figs. 13to 17, inclusive, the mechanism used with the machine being, however, only a matterof choice, although the illustrated mechanismis of my invention.

Pulley 3 is loose and has a toothed clutch member 76, which may be engaged bya shiftable clutch member 77 in well-known manner. The shiftable clutch member 77 has an annular groove which receives the inner ends of pins 7S, projecting from the yoke 79 of a lever 80, pivoted to the frame 1 of the machine and which has pin-and-slot connection at 81 with a crank-arm S2 on a rock-shaft 83, journaled in suitable hangers on the machineframe. The lever 80 is separated a short distance away from the crank-arm, so as to permit of the longitudinal shifting of the rockshaft for the purpose to be stated hereinafter. A hand-lever S4, pivoted to the front of the frame 1 at 85, at its forked lower end 86 enters the groove of a grooved sleeve 87 of the rockshaft, which with a fixed sleeve 8S on the opposite side of the lug 89 on the frame 1 form stops in striking the lug to limit the inward and outward movements of the rockshaft bythe movement of the hand-lever. The shaft S3 may rock, its rocking in one direction being caused by a spring 90 or its equivalent and in the other direction .by conprojecting upwardly in the plane of a lug 95 on .the shaft 83.

The lug 95 has two shoulders 96 97, formed by a notch 98, the width of which is approximately the distance that the contacts 91 92 are laterally removed from each other in a direction parallel with the rock-shaft S3, so that in the normal unshifted position of the rock-shaft the shouldered parts of the l-ug will lie vertically above the contacts 91 92 in the path of movement of the contacts.

The operation of the machine and of the illustrated mechanism which may be used to operate it is as follows: Steam is let into the steam-chests 10 13 to heat the brim-clamps, and hat-block is. heated from burner 53. A

hat to be blocked is now slipped over the part of the hat-block which projects above the brim-clamp to facilitate centralization, the brim being moved down, so as to rest on the lower brim-clamp or plate. The operator then shifts the hand-lever 84 against the action of its spring, thereby releasing the lu'g 95 from the contact 91 and allowing the spring 90 to rock the shaft 83, so that the parts are moved from the position shown in Fig. 13 to that shown in Fig. 14 and the clutch memv bers are engaged, thereby starting the machine. The movable heated brim-clamp 12 now moves under gravity toward the heated brim-clamp 11. Before the brim-clamp 12 comes to a stop steam is let on automatically by the operation of the valve 69 from the shoe 74, so that the hat is steamed in the machine. The hat-brim is then clamped or pressed by the movable brim-clamp 12; but just before the final squeezing or ironing pressure effected by the action of the tappets 2O on the bearing-piece 22 the movable brim-clamp is moved slightly away from and then upon the hat-brim by the action of the cam projections 99 on the said tappets upon the levers 18. This sudden release of pressure and the aircirculating space formed between the movable brim-clamp and the hat-brim permit any steam remaining in the hat-brim to escape before the final pressure, as just stated, is imparted to the hat-brim. The escaping of the steam allows the brim to dry, so that when taken from the machine after final pressing it is not apt to warp, Vand being thoroughly dried out is in perfect condition to finish. As soon as the hat-brim is clamped the tappets'47 operate on the levers 4to move the heated hat-block into the hat-crown, and during this movement of the hat-block the ends of the tappets 47 move into recesses 100 in the said lever, thus interrupting the pushing movement, and then suddenly the hatblock is pushed completely into the hat-crown by the action of the tappet on the cam projection lOl on the same lever. Thus the hat-block is not pushed'directl y fullinto the hat-crown,

. but intervals are produced, so that the crown IOO TIO

10 and the clutch members will be automatically disengaged by the striking of the shouldeil portion 96 of the lug 95 by the contact 92, as shown in Fig. 15. The machine being thus brought to rest the hat is kept therein under the action of heat for a sufficient length of time to assure that the same is properly blocked and all creases and Wrinklessmoothed out. Having been blocked, the hat is ready to be removed, so that another may be placed in the machine. For this purpose the operator again operates the handle 84 to shift the shouldered portion 96 of the lug 95 oi the contact 92, which permits the spring 90 to rock the shaft 83, as shown in Fig. 16, and again engage the clutch members. The machine .being started, the hat-block-is automatically lowered and the movable brim-clamp automatically raised, and at the completion of these movements the contact 91 strikes the shouldered portion 97 of the lug 95, as shown in Fig. 13, and automatically stops the machine. The blocked hat may now be removed and another hat to be blocked placed in position. The machine operates automatically to block the hat and to release the same after it is blocked.

It will be seen from the foregoing that the machine herein described is a power-driven hat-blocking machine, in which are combined means operated by hand for connecting the machine with the driving power, bri m-clamps, means operating automatically after the machine has been connected with the driving power for closing the clamps, a hat-block, means operating automatically after the clamps are closed for bringing the hat-block into the blocking position, and means operating automatically after the clamps have been closed and the hat block has been broughtinto blocking position for disconnecting the machine from the power, leaving the clamps closed and the block in blocking position, means operated by hand for again connecting the machine with the driving power, means operating automatically after the machine has been so again connected for opening the clamps and removing the block from the blocking position, and means operating automatically after the clamps have been so opened and the block removed from blocking position .for again disconnecting the machine from the driving power.

Since the operation of blocking requires some time and the operator is called upon to do nothing but place a hat in position and throw a lever, he can start one machine and leaving it to operate automatically go to another, then to another, thus starting four or five machines before it is necessary for him to return to the first machine to take the blocked hat out of the machine and put another in its place. 4
