HAT-FORMING MACHINE.

Specification of Letters Patent.

Patented Apr. 24, 1917-.

To all whom z't'may concern:

Be it known that I, JOHN S. BUCKMAN, a citizen of the United States, residing at Elmhurst, county of Queens, Long Island, State of New York, have invented certain new and useful Improvements in Hat-Forming Machines, of which the following is a specification.

This invention relates to hat-forming machines, and'more particularly to machines used for pressing and permanently setting cloth and buckram crowns, brims and tips used in making up hats.

In operating hat-forming machines of the construction now largely used in the trade, two operatives are required to place the ma terial between the Lipper and lower dies and to properly stretch and hold it so that the dies will smoothly shape the material.

The main object of this invention is to provide a hat-forming machine with means for holding one side of the material in proper relation to the pressing dies, in order that the material may be lproperly placed and stretched smoothly over the lower die by a single operative.

A further object of the invention is to provide a hat-pressing and forming machine in which the material to be pressed may be properly stretched and held, and the press operated by a. single operative.

A further object of the invention is the provision of an attachment for holding the material at one side of the press, which is capable of adjustment to adapt it for use in connection with forming dies of various sizes and shapes.

Another important object of the invention is to provide an attachment for the purpose set forth, which may be applied to the standard forms of hat pressing machines without altering or mutilating existing ma` chines, and which maybe readily attached and removed. i

In the drawings, Figure l is a side elevation of a well-known form of hat pressing machine equipped with the material holding attachment, the dies and gripping jaws being shown in their normal open position;

Fig. 2 a side elevation partly in section,

showing the relative positions of the parts during the pressing operation;

Fig. 3 a rear elevation with the parts in the position shown in Fig. 2;

Fig. 4 a detail front elevation of the material holding attachment, the parts being shown in the position assumed just before the dies come together; and

FiO. 5 a top plan View of the attachment.

Re erring to the various parts by numerals, l designates the frame of the machine which, of course, may be of any suitable construction. A table or bed plate 2 is rigidly mounted in the frame, and a blocking die '3 is rigidly supported upon a suitable pedestal at the center of the table. The blocking die is provided with an annular shoulder 4, the shaping part 5 of the die extending upwardly from said shoulder, as clearly shown in Figs. l and 2. This shaping portion of the die may be of any desired contour.

The upper die or presser ring 6 depends from, and is rigidly connected with a vertically reciprocable cross-head or spider 7, directly above the blocking die 3. The cross-head 7 is carried by two vertically reciprocable rods 8, said rods being connected at their lower ends to a cross-head 9 mounted in the frame of the machine, below the table 2. Connected to the lower crosshead 9 is a treadle mechanism l0, operated by the treadle 1l to bring the presser ring down upon the blocking die 3, suitable springs connecting said treadle mechanism with the frame for returning the parts to their normal position and lifting the presser ring above the blocking die. A. latch 13 ad" justably mounted'on a rod 14 connected to the frame of the machine is provided, for the purpose of locking the treadle in its lowermost position during the pressing operation. All the parts heretofore described are of well-known construction.

EXtending transversely of the machine at a point back of the blocking die 3, is a rectangular frame comprising a bottom plate l5, side plates 16 and a top cross bar 17 rigidly connected together. This frame may be made in the form of an integral casting mally yieldably held at the limit if desired, and it is detachably and adjustably mounted on the table 2. I prefer to connect the frame to the table by means of U-clamps 18, one end of the clamps being passed through openings 19 in the side plates 16 of the frame. This enables the frame to be readily attached to standard forms of pressing machines without the necessity of altering or mutilating the machines, and also provides a simple means for quickly adjusting the frame on the plate 2 to properly position it with respect to dies of various shapes and sizes.

A yieldable cloth-gripping jaw or plate 20 is slidably mounted in the frame, the jaw being vertically reciprocable and guided by a pair of vertical rods 21 secured at each side of the frame. r1`he jaw 20 is normally held at the top of the guide frame by light coiled springs 22 surrounding the guide rods, stops 23 being provided at the top of the frame to limit the upward movement of the jaw. A stop rod 24 extends across the frame,y with its ends passing through apertures in the side plates 16, and this stop rod is adapted toy limit the downward movement of the jaw 20 for a purpose hereafter' described. A series of apertures is preferably provided in each side plate in order that the position of the stop rod in the frame may be varied as conditions may require.

Mounted upon the top of the rearwardly extending arm 7a of the cross-head 7 is a plate or cross bar 25, extending transversely of the machine above the guide frame in which the jaw 2O is mounted. This cross bar 25 is adjustable back and forth along the arm 7?, and is also capable of lateral adjustment, being connected to the arm 7ZL by a bolt 26 passing thro-ugh a slot 27 in the cross bar 25 and through the usual slot 28 extending longitudinally of the arm 7a. Means is thus provided for adjusting the bar 25 to correspond with the adjusted position of the guide frame.

Suspended from the bar 25 by a pair of guide rods 29 at a point .above the cloth grippingjaw 20,isa second cloth gripping j aw 30. The guide rods 29 pass freely through apertures in the bar 25, and have cotter pins passedthrough apertures in their upper ends, to limit the downward movement of the jaw 30 with respect to the cross bar 25. A series of apertures is preferably provided at the upper end of each rod in order that the positions of the Cotter pins may be varied to adjust the jaw 30 vertically with relation to the dies. Obviously, any suitable means other than cotter pins may be employed for restraining the downward movement of the guide rods. The upper jaw 30 is norof its downward movement, at a point directly above the jaw 20, as clearly shown in Fig. 1, by means of heavy coiled springs 31 surrounding the guide rods 29. A pair of depending guide rods 32 are rigidly connected to the upper jaw 30 and extend downwardly through guide openings in the lower j aw 20. These rods 32 are of suf- .n

ficient length to extend through the jaw 20 when the jaws are their normal open position, and serve to maintain the jaws in their proper relative positions, one directly above the other.

n the operation of the device, after the dies have been properly heated, the material to be shaped is passed between the dies from the front of the machine, and its rear edge laid upon the upper face of the jaw 20. The operati-ve then grasps one corner of the front edge of the goods in either hand and presses down upon the treadle 11 with his foot. This causes the upper cross-head 7 to move downwardly, carrying with it the presser ring 6 and upper jaw 30, until the

jaws

20 and 30 come together and grip the cloth along its rear edge. A further downward movement of the treadle causes the cross-head to further lower the presser ring 6, and since the springs 31 are heavier than the springs 22 the upper jaw also continues to move downwardly and forces the lower jaw downwardly, as shown in Fig. 4. 1n the position of the jaws shown in Fig. 1l the cloth is substantially on a line with the top of the blocking die 3, and in position to be smoothly and tightly stretched over the die 3 by the operative pulling on the corners of the front edge of the goods. Further depression of the treadle brings the clamped jaws against the stop rod 24, and further downward movement of the aws is prevented. Further downward move-y ment of the cross-head 7 and presser ring (5 in response to depression of the treadle is permitted, however, the cross-head com-v pressing the springs 31 and moving downward until the parts assume Athe position shown in Figs. 2 and 3, with the dies in pressing position. WV hen the treadle is released the usual treadle springs and springs 22 and 31 return the parts to the position shown in Fig. 1.

An important feature of the invention is the provision of means at the back of the press for gripping the rear edge of the goods, the gripping means being adapted to carry the rear edge of the cloth down past the plane of the crowned portion of the stationary blocking vdie in advance of the movable presser ring. This enables a single operative standing at the front of the machine to smoothly stretch the material by grasping the corners of the front edge of the fabric in each hand and pulling thereon as the fabric is carried down over the stationary blocking die in advance of the presser ring, when the foot-operated lll@ treadle is depressed by the operative. The advantages of hand smoothing and stretching of the goods are thus secured, while but a single operative is required to operate the machine and stretch the material over the blocking die.

Another important feature of the invention is the provision of a cloth gripping attachment capable of adjustment to adapt it for use in connection with different forms and sizes of dies. It will also be observed that. the device may be readily attached to the standard types of hat-forming machines without altering` or mutilating the machines.
